Many people have a wrong understanding that security doors are regarded as security doors. Security door is a security door used in our home and other places, with a solid shell. Security door is an access control device for security inspection in airports, subway stations, libraries, cinemas, gymnasiums and other public places. It is usually used with other access control systems and security systems. The following Tuba Rabbit Bian Xiao introduces the installation steps of the security door.

Installation steps of safety door

Before starting the operation, the installer should prepare impact hammer, socket wrench, spirit level, wire pendant, tape measure, hammer, screwdriver, iron file, steel chisel, cutting machine, hacksaw and expansion bolt.

Step 1: Set the cardinality. The installer will weld and fix the bottom plate and the vertical beam of the middle derrick according to a certain size to ensure that the middle guide rail and the bottom plate are attached together, and the angle between them must be vertical and cannot be skewed.

Step 2: weld the guide rail. The installer welds the upper parts of the guide rails at both ends with the bottom plate, and then welds the vertical beams at both sides of the derrick. Weld is set as intermittent symmetrical weld to ensure the vertical angle of the guide rail, and pay attention to keep a proper distance from the middle guide rail.

Step 3: Install the beam. The installer hangs the beam on three guide rails to weld it with the bottom plate in a horizontal state, and pays attention to the installation direction of the beam.

Step 4: Install accessories. The installer connects the electric hoist with the beam with bolts, and then locks it. Before lifting the motor, correctly assemble the wire rope and related parts, and then connect the cable length to the control room. Lubricate pulleys, wire ropes and other parts, and keep the correct installation direction.

Step 5: Complete the installation. After the commissioning motor runs normally, the installer lifts the safety door, assembles other components together to ensure that there is no jamming or skew, checks whether the pulley rotates flexibly and whether the connector is fastened, and finally lifts the safety door to a proper position, and welds four limit bottom plates according to the set distance to the rail surface.

Step 6: Test and adjust. After all the components of the safety door are installed, the installer should carry out trial operation, adjust the position of motor resistance and switch, and ensure normal use.

Finally, Tuba Rabbit Bian Xiao has to say that the correct installation of the safety door is related to the future use process. Safety door is an important part of the access control system of indoor buildings at present. The appearance of the safety door is made of brushed stainless steel, which is very modern and beautiful. One or more passages are usually set at important entrances of buildings to help monitor the passage environment.
