[0024] Reference Figure 1 , 2As shown, the platform vehicle of the utility model, which is convenient for operating the outer surface of the driver's room of a rail transit vehicle, comprises: a main frame 1, universal wheels 2, track wheels 3, a working platform 4, a guardrail 5 and an anti-dropping clamp 6; the main frame 1 is a rectangular frame, and the main frame 1 serves as a supporting frame of the platform vehicle; the universal wheels 2 are arranged in four numbers, and the universal wheels 2 are connected to the lower end surface of the main frame 1, and the universal wheels 2 are used for moving the main frame 1; the track wheels 3 are arranged in four numbers, and the track wheels 3 are connected to the lower end surface of the main frame 1, and the track wheels 3 are connected to the lower end surface of the main frame 1. The track wheel 3 is arranged on the maintenance track, and the track wheel 3 can move along the maintenance track; the working platform 4 is fixedly arranged on the upper end surface of the main frame 1, and the working platform 4 adopts a 3mm aluminum patterned plate; the guardrail 5 is connected to the upper end surface of the main frame 1, and the guardrail 5 is arranged around the working platform 4; the anti-slip clamp 6 is arranged as at least one, and the anti-slip clamp 6 is arranged on the lower end of the main frame 1, the anti-slip clamp 6 is clamped to the maintenance track, and the anti-slip clamp 6 is used to connect the main frame 1 with the maintenance track.

[0025] By setting the universal wheel 2 and the track wheel 3, this platform vehicle is suitable for flat ground and rail surface. The universal wheel 2 is used for movement on flat ground, and the track wheel 3 is used for movement on the maintenance track to ensure the safety of operation. The horizontal position of the universal wheel 2 is lower than the track wheel 3, so that when the platform vehicle is pushed on flat ground, the track wheel 3 is suspended in the air. When the platform is placed in a maintenance tunnel, the track wheel 3 is placed on the maintenance track, and the universal wheel 2 is suspended above the tunnel.

[0026] In the above structure, a step support frame 7 is provided on one of the side walls of the main frame 1 , and a boarding step 8 is provided on the step support frame 7 . The boarding step 8 is used for workers to go to the working platform 4 .

[0027] In the above structure, the guardrails 5 are provided in three pieces, and the guardrails 5 are provided in a "U" shape, and the boarding steps 8 and the three guardrails 5 are respectively located on four sides of the main frame 1. The three sides of the working platform 4 are guardrails 5, and one side is reserved for working on the electric passenger car.

[0028] In the above structure, a fixing sleeve 11 is provided on the outer wall of the main frame 1, and the fixing sleeve 11 is cylindrical. The cylindrical rod of the guardrail 5 is arranged in the fixing sleeve 11, and the guardrail 5 and the fixing sleeve 11 are connected by fasteners.

[0029] In the above structure, the lower end of the main frame 1 is provided with an anti-dropout clip placement box 12, and the anti-dropout clip placement box 12 is used to store the anti-dropout clip 6. When the platform vehicle is moved, the anti-dropout clip 6 can be placed in the anti-dropout clip placement box 12 to avoid the anti-dropout clip 6 being placed randomly.

[0030] In the above structure, an annular groove 31 is provided on the outer circumference of the track wheel 3, and the annular groove 31 is used to limit the track wheel 3 on the inspection track.

The fixing plate 1 63 and the fixing plate 2 64 are respectively connected to the two ends of the opening of the V-shaped connecting plate 62. The stud 65 is threadedly connected to the fixing plate 1 63. The knob 66 ​​is connected to one end of the stud 65. The end of the fixing plate 2 64 away from the V-shaped connecting plate 62 is provided with a hook 67. The end of the stud 65 located between the fixing plate 1 63 and the fixing plate 2 64 is provided with a wear-resistant sheet 68. The working principle of the anti-slip clamp 6 is as follows: initially, the knob 66 ​​is rotated to move the stud 65 away from the fixing plate 2 64, and the platform vehicle is moved to the designated working position, and is inserted into the inspection track from the opening position between the hook 67 (the hook 67 is arranged toward the side of the fixing plate 1 63) and the fixing plate 1 63, and then the knob 66 ​​is rotated to move the stud 65 toward the side of the fixing plate 2 64 until the fixing plate 1 63 and the wear-resistant sheet 68 are stably released from the inspection track. At this time, the anti-slip clamp 6 is connected to the inspection track, and the platform vehicle is connected to the inspection track, which facilitates the fixation of the platform device during operation and improves its stability.

[0032] The main frame 1 of the above structure is made of SUS304 stainless steel, and is welded by a number of square tubes and round tubes. The weight of the main frame 1 is limited to 40kg, and it can also carry a load of 150kg. The bottom of the main frame 1 is reserved with locking screw holes, and the screws are standard parts, which are easy to replace at any time to avoid waste of resources caused by recasting.

[0033] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods.
