Use skills of excavator:
1, operation technology
First of all, we must confirm the surrounding situation. When rotating, pay attention to the surrounding obstacles and terrain and operate safely; When working, confirm the front and rear direction of the crawler to avoid overturning or collision; Try not to face the final heading face in the direction of excavation, otherwise it will easily damage the walking motor or hose; When working, it is necessary to ensure that the left and right tracks are in complete contact with the ground to improve the dynamic stability of the whole machine.
2. Effective mining methods
When the bucket cylinder and connecting rod, bucket cylinder and bucket arm form 90 degrees, the digging force is the largest; When the bucket teeth keep an angle of 30 degrees with the ground, the excavation force is the best, that is, the soil cutting resistance is the smallest; When digging with a stick, make sure that the angle of the stick is between 45 degrees in front and 30 degrees behind. Using boom and bucket at the same time can improve excavation efficiency.
Step 3 dig stones
Using a bucket to dig rocks will cause great damage to the machine and should be avoided as far as possible; When excavation is needed, the position of the machine body should be adjusted according to the crack direction of the rock, so that the bucket can be shoveled out smoothly for excavation; Insert the bucket teeth into the cracks in the rock, and use the digging force of the bucket arm and bucket to dig (pay attention to the sliding of the bucket teeth); Unbroken rocks should be broken before digging with a bucket.
4, slope leveling operation
When planing, put the machine flat on the ground to prevent the machine from shaking. It is very important to master the coordination of the movement of the boom and the stick and control the speed of the boom and the stick.
5. Loading operation
The machine body should be in a horizontal and stable position, otherwise it is difficult to accurately control the rotary unloading, thus prolonging the operation cycle time; When rotating at 1 80 degrees, keep a proper distance between the fuselage and the truck to prevent the tail of the fuselage from colliding with the truck; As far as possible, rotate the installation on the left side, which will broaden the field of vision and improve the operation efficiency, and at the same time correctly grasp the rotation angle and reduce the rotation time; The truck is located in the forest lower than the excavator to shorten the lifting time of the boom and have a good line of sight; Install sand and stone first, and then enlarge the stone to reduce the impact on the trunk.
6, soft area or water operation
When working in soft soil area, we should know the degree of soil looseness, and pay attention to limit the digging range of bucket to prevent accidents such as landslide and deep sinking of car body.
When working in water, pay attention to the allowable water depth range of the car body (the water surface should be lower than the center of the supporting sprocket); If the water level is high, the inside of the slewing bearing will be poorly lubricated due to the entry of water, the engine fan blades will be damaged due to the impact of water, and the circuit components will be short-circuited or open-circuited due to the entry of water.
7. Lifting operation
When using hydraulic excavator for hoisting operation, it is necessary to confirm the surrounding conditions of the hoisting site, use high-strength hooks and wire ropes, and try to use special hoisting equipment when hoisting; The operation mode should be micro-operation mode, and the action should be slow and balanced; If the length of lifting rope is appropriate, too long will make the hanging object swing greatly, which is difficult to control accurately; Adjust the position of the bucket correctly to prevent the wire rope from slipping; Construction personnel should try not to get close to the lifting objects to avoid danger caused by improper operation.
8, smooth operation method
When working, the stability of the machine can not only improve the working efficiency and prolong the life of the machine, but also ensure the safety of operation (put the machine on a flat ground); The stability of the rear drive sprocket is better than that of the front side, which can prevent the main reducer from being impacted by external force; The wheelbase of the track on the ground is always greater than the track pitch, so the stability of forward work is good, and lateral operation is avoided as far as possible; Keep the digging point close to the machine to improve the stability and excavator; If the excavation point is far away from the machine, the operation will be unstable because the center of gravity moves forward; The stability of lateral excavation is worse than that of forward excavation. If the digging point is far away from the center of the fuselage, the machine will be more unstable. Therefore, the excavation point should keep a proper distance from the center of the machine body to make the operation balanced and efficient. 9, noteworthy operation
The hydraulic cylinder is equipped with a buffer device, which can gradually release the back pressure when it is close to the end of the stroke; If the piston is subjected to impact load after reaching the end of the stroke, it will directly hit the cylinder head or cylinder bottom, which may easily cause accidents, so try to leave a gap when reaching the end of the stroke.
The rotating earth-moving operation will cause abnormal stress to the bucket and working device, which will lead to deformation, weld cracking and even pin shaft fracture. This operation should be avoided as far as possible.
Using the weight of the fuselage to excavate will cause the abnormal stress state of the slewing bearing, similarly ... >; & gt
Question 2: What are the requirements for learning excavators? Good physical fitness, accurate judgment, good hand-foot coordination and good eyesight!
Question 3: How about learning to drive an excavator now? How long will it take? If you study excavators, apprentices always do this at first. When they grow up, it takes three years to become masters. But now there are too many excavators and not enough drivers, so many of them are just learning to be masters. As long as they don't drive for 3000 hours, don't say they can! !
Question 4: How much does it cost to learn to drive an excavator? 16~25 This period is the easiest time to learn and the easiest time to accept. About 6000 excavators, studied in slow three for several months. It's been almost a month, and the real skill depends on how you learn it yourself. If you just want to learn and don't practice after passing the exam, you won't have real skills.
Question 5: How about learning to drive an excavator? I can only say that I have one more survival skill, that's all. As you said, there are more people studying now, and it is unrealistic to want to earn more. However, you cannot completely deny the existence of this industry. If you have a certain relationship in the construction industry, you can also find a relatively high-paying and relaxed job.
If you want to achieve great things, then this can only be the basis for your first entry into society.
Question 6: How long does it take to learn to drive an excavator? 10 minutes. If you learn an excavator, you will become an apprentice from the beginning. If you want to learn, you can become a hand in three years. But now there are too many excavators and not enough drivers, so many just learn how to be masters. Don't say yes as long as you don't drive for 3000 hours! !
Question 7: I just started to learn how to learn how to get along with teachers.
Question 8: How to learn excavator? Learn from the excavator master who works on the construction site first. Practice more and learn better skills; A master takes a student and teaches with heart; In the process of learning, you can also change to a master after learning well at one stage, so that students can learn more comprehensive skills. Students can go to the construction site for a few days and then pay the tuition. Tuition fees are charged according to (need to arrange work) and (need not arrange work). There are two tuition packages that don't need to arrange jobs: (two thousand Wu Bai dollars, seven thousand yuan) Package 1: (1) Suitable for students who are already proficient in excavator operation and want to learn more and do more. (2) Students who have their own employment channels. (3) Students have been on the computer for 30 hours. Tuition: [2,500 yuan] Package 2: (1) is suitable for students who have never studied excavators. (2) Students who have their own employment channels. (3) Students can operate on the computer for 200 hours (until they can learn the technology)+Recommended work tuition: [7,000 yuan] Need to arrange work with tuition package: 9,000 Wu Bai yuan package 1: (1) Suitable for students who have never studied excavators. (2) Students without employment channels. (3) The trainees have been operating on the computer for 200 hours (until they can learn the technology)+arranged work (working independently for one month)+recommended work tuition fee for the next few years: [9,000 Wu Bai dollars] The intended trainees are newly arrived and admitted after passing the five-day test (physical fitness, theoretical learning ability of excavators, and whether they are addicted to the Internet). Second, during the training period, students will take good care of themselves. Generally, you can eat and live on the construction site. 4. At present, jobs can be arranged in Chongqing, Sichuan, Zhejiang, Shanghai, Jiangsu and Anhui. The salaries of skilled teachers are: 3300-4000 yuan in Sichuan, 3500-4500 yuan in Chongqing, 3200-4000 yuan in Zhejiang, 2000-3000 yuan in Jiangsu and 2000-2600 yuan in Anhui. We can always help students arrange jobs in the above provinces. At present, there is a great demand for excavator drivers abroad (Angola, Vietnam, Cambodia, Russia and other countries in Africa). The salary is 600-800 dollars, and some countries have high technical requirements for excavators, and the salary 1000 dollars or more. If there is a place with better treatment, we will inform the trainees trained here in time. Through an example, this paper introduces the training process of excavator students: on June 3, 2007, a student came to the Shanghai demolition site. Name: Xiao Peng (pseudonym) Hometown: Yunyang County, Wanzhou District, Chongqing Age: 19 years old. He worked as a steel bar picker in a house demolition site for a year. His family thinks that there is no future for young people to work on the construction site, and it is a long-term solution to consider learning a technology. Learn what? There are many excavators in the construction site where houses are usually demolished, and the salary and environment of excavator drivers are OK (there is air conditioning in excavators, which is warm in winter and cool in summer). The key is to see if the driver who used to drive the excavator can drive the excavator himself when he meets a good opportunity. For young people, it is still promising to learn excavators. The family decided to let him learn to dig. After arriving at our construction site, he passed the tests of physical fitness, theoretical learning ability of excavators and whether he was addicted to the Internet. After passing the exam, he was arranged to practice with Master Wang (a pseudonym) who was working on the construction site. Master Wang has worked for the excavator boss for more than four years. The excavator he drives is a Shenzhen-Hong Kong 230-6 excavator with good technical level. The excavator owner and the site owner also spoke highly of him. Master Wang dug a live site, and the next time there is work on the site, there will be no other diggers to pick it up. The website owner specifically asked Master Wang to do this job. I can only trust Master Wang's technical level. Master Wang's excavator has a high technical level and is responsible for doing things. The salary given to him by the excavator boss is also 4000 yuan per month. When Master Wang's excavator digs the foundation of the house at the construction site, he teaches Xiao Peng to practice digging the foundation of the house. When the excavator was building roads in the development zone, he taught Xiao Peng to practice building roads; When excavators dig stones and load cars on the mountain, they teach Xiao Peng to practice digging stones and loading cars. After the patient teaching and painstaking study of Master Wang, the operation level of our excavator has improved rapidly. It took Xiao Peng only one month and twenty-five days to learn the excavator on the construction site and arrange the work. Xiao Peng is now excavating in Shanghai, and his specific place of work is: Shangnan, the site of Pudong World Expo ... >>
Question 9: How to learn to drive an excavator? Be careful not to panic and worry, because the excavator is a hydraulic system, which is more flexible. The handle is eight movements, in short, four movements, because they are corresponding. That's what I'm talking about. Talking too much will make you more confused. Give it a try. Good luck.
