[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 A subway vehicle maintenance platform includes a support frame 1, a working platform 2 fixedly mounted on the top of the support frame 1, and guardrails 3 fixedly mounted on all four sides of the working platform 2. An installation slot 4 is provided inside one side of the guardrail 3, and a storage structure 5 is fixedly mounted inside the installation slot 4. The storage structure 5 includes a fixing plate 51, which is fixedly connected to the guardrail 3. Two support rods 52 are fixedly mounted on one side of the outer surface of the fixing plate 51, and a grooved plate 53 is fixedly mounted on the other side of the support rods 52. Five hinge plates 54 are provided on one side of 53. A hinge member 55 is hingedly installed at the connection of the five hinge plates 54. Two of the hinge plates 54 are hingedly connected to the groove plate 53. Oxford cloth 510 is fixedly installed below the five hinge plates 54. A support plate 56 is fixedly installed on the top of the groove plate 53 and the farthest hinge plate 54. A threaded rod 57 is installed in the internal thread of one support plate 56. A handle 58 is fixedly installed at the end of the threaded rod 57. A limit rod 59 is movably installed inside the other support plate 56.

[0024] Please see Figures 1-2 The threaded rod 57 is rotatably connected to the corresponding support plate 56, and the limiting rod 59 is fixedly connected to the corresponding support plate 56. A ladder 6 is fixedly installed on one side of the outer surface of the support frame 1, and the ladder 6 is fixedly connected to the guardrail 3. Four sets of reinforcing ribs 7 are fixedly installed inside the support frame 1. Four casters 9 are installed at the bottom of the support frame 1, and the four casters 9 can be locked.

[0025] The reinforcing ribs 7 provide overall support and reinforcement to the support frame 1, improving the stability of the device. The guardrail 3 below the guardrail prevents other parts from falling off the work platform 2.

[0026] Please see Figures 2-5 An adsorption structure 8 is fixedly installed on both sides of the inner wall of the support frame 1. The two adsorption structures 8 include a fixing frame 81. The two fixing frames 81 are fixed to the inner wall of the support frame 1 by bolts. A negative pressure generator 82 is fixedly installed on the top of the two fixing frames 81. A negative pressure suction cup 83 is installed on one side of the two negative pressure generators 82, and the two negative pressure suction cups 83 penetrate the support frame 1.

[0027] During the use of the device, by aligning the guardrail 3 with the vehicle body from the opening side and bringing it close, the two negative pressure suction cups 83 come into contact with the vehicle body. Then, the two negative pressure generators 82 are activated, which creates negative pressure inside the negative pressure suction cups 83 to attract the vehicle body, thereby making the support frame 1 initially stable. The stability of the device can be greatly improved by locking the four casters 9.

[0028] Working principle: When a subway vehicle maintenance platform is in use, under normal conditions, the five hinged plates 54 are hinged together, and the Oxford cloth 510 is naturally folded, thus not occupying external space. When using the device, first align the guardrail 3 with the car body from the opening side and bring it close, so that the two negative pressure suction cups 83 contact the car body. Then, activate the two negative pressure generators 82 to create negative pressure inside the negative pressure suction cups 83, thereby adsorbing the car body, thus making the support frame 1 initially stable. Locking the four universal wheels 9 can greatly improve the stability of the device. Then, the operator rotates the handle 58 to make the threaded rod 57 rotate inside the support plate 56 and drive the hinged plates 54 connected to it to move. At the same time, with the support of the limit rod 59 on the side, the five hinged plates 54 can be opened to form a rectangular container, and the Oxford cloth 510 at the bottom unfolds with it. In this way, the operator's maintenance tools can be placed on the top of the Oxford cloth 510 without occupying the effective operating area of ​​the platform, avoiding the risk of tripping or collision when the personnel move.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
