[0002] Rail transit refers to a type of transportation vehicle or transportation system in which operating vehicles need to travel on specific tracks. During the operation and maintenance of the rail transit system, various instruments and cables need to be installed inside the operation and maintenance chassis and controlled through the operation and maintenance chassis.

[0003] For example, the utility model: "A power supply and operation and maintenance device for rail transit", with the announcement number: "CN221009629U", uses a rolling shutter-shaped opening and closing door assembly, which can be opened and closed in an inward-retracting manner without occupying external space. While saving installation space, it can provide more activity space for staff, which is suitable for various installation environments and improves flexible installation and usability. However, during the implementation of this patent, the instruments and cables are installed inside the chassis, which is not convenient for staff to take them out and maintain them, and the device lacks a wire management structure, and cannot store and organize long cables, making it easy for multiple groups of cables to entangle with each other, causing chaos inside the chassis. Therefore, the research and development of new power supply and operation and maintenance devices for rail transit has received more and more attention from researchers. Utility Model Content

[0020] like Figure 1-3 As shown, a mounting hole 19 is provided at one end of the top of the operation and maintenance chassis 1 close to the door 6, and a fixing rod 18 is installed inside the mounting hole 19, a connecting plate 20 is installed on the top of the fixing rod 18, a second fixing spring 21 is installed on the bottom of the connecting plate 20, and the end of the second fixing spring 21 away from the connecting plate 20 is connected to the operation and maintenance chassis 1, the elastic action of the second fixing spring 21 causes it to pull the connecting plate 20 to move, and the connecting plate 20 drives the fixing rod 18 to move together, and the fixing rod 18 can be inserted into the first socket 8 or the second socket 17, so that the top plate 7 can be fixed to prevent the L-shaped plate 9 from continuing to move during use, which is beneficial to improving the stability of the device.

[0021] like Figure 1 As shown, wire holes 5 are evenly arranged inside the box door 6, and cables can be passed through the wire holes 5. A handle is installed at the bottom of the box door 6 away from the end of the L-shaped plate 9 to facilitate the staff to pull the box door 6 to move.

[0022] Working principle:

[0023] When in use, the staff can first pull the connecting plate 20 upwards, the connecting plate 20 stretches the second fixing spring 21, and the connecting plate 20 drives the fixing rod 18 to move together, and the fixing rod 18 can be taken out from the second insertion hole 17, so that the fixing rod 18 can release the limit of the top plate 7, so that the top plate 7 can move;

[0024] Then the staff can pull the box door 6, and the box door 6 drives the L-shaped plate 9 to move together, so that the installation tray 3 and the L-shaped plate 9 can be taken out from the operation and maintenance chassis 1 as a whole, so that the staff can install the rail transit power supply operation and maintenance instrument on the installation tray 3 and repair the instrument;

[0025] After the L-shaped plate 9 is taken out from the operation and maintenance chassis 1, the staff loosens the connecting plate 20. At this time, the elastic action of the second fixing spring 21 causes the connecting plate 20 to move downward and reset. The connecting plate 20 drives the fixing rod 18 to move together, and the fixing rod 18 can be inserted into the first insertion hole 8. The fixing rod 18 limits the top plate 7 to prevent the top plate 7 from moving further, and the L-shaped plate 9 can be fixed to prevent the L-shaped plate 9 from moving further during use.

[0026] The staff can pass the cable through the threading hole 5 and wind the longer cable around the outside of the winding tube 4. At this time, the elastic action of the first fixing spring 16 pushes the installation rod 15 to move downward, and the installation rod 15 drives the wire pressing ring 13 to move together through the guide rod 14, so that the wire pressing ring 13 presses on the cable, and the cable can be clamped and fixed, which can prevent the cable from falling off the winding tube 4, and has the effect of storing and fixing the cable, and preventing the cables from being entangled with each other;

[0027] After the inspection is completed, the staff pulls the connecting plate 20 upwards, removes the fixed plug rod 18 from the first plug hole 8, and releases the limit of the fixed plug rod 18 on the top plate 7, so that the top plate 7 and the L-shaped plate 9 can move;

[0028] At this time, the elastic action of the reset spring 10 causes it to pull the L-shaped plate 9 to move and reset, so that the mounting bracket 3 and the L-shaped plate 9 can be re-stored into the operation and maintenance chassis 1, and the box door 6 is tightly fitted with the operation and maintenance chassis 1;

[0029] When the box door 6 fits tightly against the operation and maintenance box 1, the second socket 17 moves to a position opposite to the fixed plug rod 18, and the staff loosens the connecting plate 20. At this time, the elastic action of the second fixed spring 21 pulls the connecting plate 20 to move downward and reset, and the connecting plate 20 drives the fixed plug rod 18 to move together, and the fixed plug rod 18 can be inserted into the second socket 17. The top plate 7 can be limited by the fixed plug rod 18 to prevent the top plate 7 from continuing to move, and the L-shaped plate 9 can be fixed to prevent the L-shaped plate 9 from continuing to move during use, which is beneficial to improving the stability of the device.
