Jiande anti-theft door installation

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 motor runs normally, the installer lifts the safety door, assembles other parts 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 door body of the safety door to a proper position, and welds four limit bottom plates according to the set distance from the rail surface. Step 6: Test and adjust. After the installation of all parts of the security door is completed, the installer should carry out trial operation and adjust the motor resistance and switch position to ensure normal use.
