[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] like Figure 1 to Figure 7 As shown, a bogie maintenance work platform for a straddle-type monorail train includes an operation support frame 100, wherein the operation support frame 100 includes a first platform frame 1 and a second platform frame 2, wherein:

[0030] The first platform frame 1 includes a first frame body 11, a first universal wheel 12, a first platform board 13, a first guardrail 14 and a side up-and-down staircase 15. A plurality of the first universal wheels 12 are installed at the lower end of the first frame body 11. The first platform board 13 is horizontally installed on the first frame body 11 and supported by the first frame body 11. Preferably, the first frame body 11 is a frame structure. Such a frame structure is simple to manufacture and has high strength. It can be formed by welding metal profiles. The first guardrail 14 is vertically installed on the first platform board 13 and supported by the first platform board 13. The first guardrail 14 can effectively protect the operator and prevent the operator from falling from the first platform board 13. The side up-and-down staircase 15 is installed on the first frame body 11 so that the operator can go up and down the first platform board 13. The bottom end of the side up-and-down staircase 15 is also installed with a plurality of the first universal wheels 12. Then, the first frame body 11 and the side up-and-down staircase 15 can be moved to the desired site through the first universal wheels 12.

[0031] The second platform frame 2 is provided with two, each of which includes a second frame body 21, a second universal wheel 22, a second platform board 23 and a second guardrail 24. A plurality of the second universal wheels 22 are installed at the lower end of the second frame body 21. The second frame body 21 may be moved to a desired site through the second universal wheels 22. Preferably, the second frame body 21 is also a frame structure. The second platform board 23 is horizontally installed on the second frame body 21 and supported by the second frame body 21. The operator can go up and down the stairs 15 from the side to the first platform board 13, and then walk from the first platform board 13 to the second platform board 23. The second guardrail 24 is vertically installed on the first platform board 13 and supported by the second platform board 23 to effectively protect the operator.

[0032] Each of the second platform frames 2 is hinged to one end of the first platform plate 13 through a supporting hinge shaft 3, and each of the second platform frames 2 is located below the first platform plate 13, so that each second platform plate 23 can be rotated to the bottom of the first platform plate 13 and retracted, or extend out of the first platform plate 13 and cooperate with the first platform plate 13 to form a U shape to surround the bogie. When maintenance is needed, the maintenance work platform can surround the bogie, and the operating personnel can inspect the bogie from multiple directions.

[0033] Furthermore, two work support frames 100 are provided, which are unfolded into a U shape and arranged relative to each other to surround the bogie in a U shape, so that operators can inspect the bogie from four directions, thereby improving the inspection efficiency.

[0034] Furthermore, the two work support frames 100 are detachably connected together by means of a latch 4, so that the two work support frames 100 can be fixed during maintenance, and the two work support frames 100 can be separated after maintenance and the second platform frame 2 can be folded up, thereby saving space.

[0035] Furthermore, each of the first universal wheels 12 is provided with a universal wheel brake device, and each of the second universal wheels 22 is provided with a universal wheel brake device, so that after the maintenance work platform is moved to the desired position, it can be braked by the universal wheel brake device, and it also helps to maintain the stability of the maintenance work platform.

[0036] The bogies on the train are unloaded and placed on the movable maintenance track beam, waiting to be removed for maintenance. After receiving the maintenance operation command, one of the operation support frames 100 is moved to the set position through the first universal wheel 12 and the second universal wheel 22. The two second platform frames 2 use the support hinge shaft 3 as the fulcrum and are each rotated 90° through the second universal wheel 22 to make the operation support frame 100 U-shaped. The universal wheel brake device locks the first universal wheel 12 and the second universal wheel 22 and waits for the maintenance track beam and the bogie on it to move to the operation support frame 100. Then the bogie is moved out to the side of one of the operation support frames 100 through the maintenance track beam (a mobile trolley or the like can be used to move the maintenance track beam and its bogie);

[0037] After that, another work support frame 100 is also moved to the other side of the bogie through the first universal wheel 12 and the second universal wheel 22. The two second platform frames 2 of the work support frame 100 use the supporting hinge shaft 3 as the fulcrum, and are each rotated 90° to form a U shape through the second universal wheel 22, pushing the second platform frame 2 closer to the bogie. After the two second platform frames 2 of the two work support frames 100 are close, the pin 4 is inserted into the jack on the outside of the two second platform frames 2, and the universal wheel braking device locks the universal wheel. At this time, the two work support frames 100 are combined and connected to form a mouth shape to surround the bogie, and the maintenance work platform is fixed. The operator climbs onto the maintenance work platform through the side up and down stairs 15 to perform maintenance work on the bogie.

[0038] After the inspection and maintenance work is completed, the latch 4 is pulled out, the universal wheel brake device releases the universal wheel, one of the work support frames 100 moves sideways away from the bogie, and the two second platform frames 2 rotate and close to be stored in the first platform frame 1;

[0039] Then another working support frame 100 leaves the maintenance area, and the bogie moves into the gap of the fixed track beam used for train running through the maintenance track beam. The two second platform frames 2 of the working support frame 100 are also rotated and closed into the first platform frame 1, leaving the working area to wait for the maintenance of the next bogie.

[0040] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
