[0002] The maintenance of guide pulleys for winch-type gate hoists needs to be carried out at high altitudes. Currently, the conventional method is to lower a suspended platform, but the stability of the work platform cannot be guaranteed during the process. Therefore, maintenance work is more often carried out by erecting scaffolding. Since the maintenance location is high above the ground, erecting scaffolding from the ground up has the problems of high cost and long construction period, which greatly affects the efficiency of maintenance work on guide pulleys for winch-type gate hoists. Summary of the Invention

The pressure plate is pressed and set on the top surface of the support beam. Both ends of the pressure plate are also set in U-shaped positioning parts.

[0009] In a preferred embodiment, the top surfaces of both ends of the pressure plate are flush with the top surfaces of the U-shaped positioning parts. A first pressure plate fixing plate is installed on both ends of the pressure plate. The first pressure plate fixing plate is "Z" shaped. The upper horizontal part of the first pressure plate fixing plate presses against the top surface of the end of the pressure plate. The lower horizontal part of the first pressure plate fixing plate is provided with threaded holes. Anchor bolts are installed in the threaded holes to connect and fix the lower horizontal part of the first pressure plate fixing plate to the ground.

[0010] In a preferred embodiment, the bottom surface of the pedal is provided with a clamp with a central angle exceeding 180°, and the clamp is securely fastened to the bottom crossbar.
