[0002] During the maintenance work of a hydropower station, taking the gate of the lock chamber as an example, there are two movable pulleys or two fixed pulleys. When the two pulleys are to be repaired, two separate maintenance platforms need to be configured. There is no connection between the platforms. The maintenance personnel need to climb down from one platform and then climb onto another platform. In addition, the height of the platform is relatively high, which leads to low efficiency and safety hazards. Therefore, realizing the connection between the two platforms is the most effective way to improve the maintenance work.

[0003] The current method is to directly build panels between two maintenance platforms as an aisle, which makes the aisle too simple and cannot guarantee the safety of people walking on the aisle. When a fixed-structure aisle is installed on the maintenance platform, the entire platform cannot be hoisted and installed in place due to on-site environmental factors. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a connecting corridor between maintenance platforms, which can ensure the safe and stable connection between two maintenance platforms, facilitate the installation and removal of the platforms, and improve the efficiency of maintenance operations.

[0006] An aisle panel is arranged on the top surface of the middle aisle truss, and telescopic fence bodies are arranged on both sides above the aisle panel.

[0007] In a preferred solution, a roller guide groove frame is respectively provided on both sides of the platform truss, and a roller is respectively provided on both sides of one end of the platform truss, and the roller is located in the roller guide groove frame.

[0008] In a preferred solution, an electric push rod is installed and fixed in one end of the middle aisle truss away from the platform truss, and the push rod part of the electric push rod extends laterally to the end of the platform truss away from the middle aisle truss and is fixed.

[0009] In a preferred solution, truss bottom butt plugs are provided on the bottom surfaces of the butt ends of the two middle aisle trusses. The truss bottom butt plugs are tooth-shaped structures. The two sets of truss bottom butt plugs are staggered and inserted into each other's gaps to form a connection.

[0010] In a preferred solution, the aisle panels on the two middle aisle trusses are provided with aisle panel docking slots on the docking ends, the aisle panel docking slots are tooth-shaped structures, and the two groups of aisle panel docking slots are staggered and inserted into each other's gaps to form a connection.

[0011] In a preferred solution, the telescopic fence body on the aisle panel includes a plurality of fence uprights, and the lower ends of the fence uprights are provided with moving wheels, and the moving wheels can roll on the aisle panel;

[0012] The fence upright pole at one end is connected and fixed to the end of the platform truss, and the fence upright pole at the other end is fixedly connected to one end of the middle aisle truss.

[0013] The utility model provides a connecting corridor between maintenance platforms, which has the following beneficial effects by adopting the above structure:

[0014] (1) The retractable middle aisle can achieve a stable connection between the two maintenance platforms after they are installed, and effectively protect the aisle, shortening the time for personnel to move between platforms and improving maintenance work efficiency;
