It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application. Figs. 1-2 In order to make the purpose, technical scheme and advantages of the present application more clear, the following will be further described in detail by combining with the drawings and embodiments of the present application. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0017] The utility model discloses a tram bogie hoisting tool, including installation base plate 1, the displacement adjusting assembly of being placed in installation base plate 1 both ends, the rotatory mechanism 2 of being provided with in installation base plate 1 top, the top of rotatory mechanism 2 is provided with the lifting ring 3 for hoisting. In order to hoist more safe and stable, the end of installation base plate 1 all is provided with the lifting ring. Installation base plate 1 bottom is connected with the bogie installation component, the bogie installation component is used for connecting with the bogie, and the bogie installation component is connected with installation base plate through the installation adjusting hole 11 of being opened on installation base plate. The bogie adjusting assembly includes the telescopic link 4 of being arranged perpendicularly to installation base plate and the fastening disc 41 of being detachably arranged at the bottom of telescopic link 4, and the fastening disc 41 is screw connection with telescopic link. The diameter of fastening disc 41 is greater than the diameter of the positioning hole on the bogie. When connecting with the bogie, first, the end of telescopic link 4 is inserted into the positioning hole of the bogie, and then, the fastening disc 41 is connected with telescopic link from the bottom of the positioning hole, so that the connection of installation base plate and the bogie is realized. The installation adjusting hole 11 is provided with multiple groups, which is used for adapting the bogie of different specifications and sizes.

[0018] The adjusting assembly includes X adjusting cylinder 5 arranged at the bottom of the installation base plate, Y adjusting cylinder 6 connected below X adjusting cylinder 5, and X adjusting cylinder 5 drives Y adjusting cylinder 6 to realize displacement in X direction when X adjusting cylinder 5 works.

[0019] Specifically, X adjusting cylinder 5 is arranged at one side of the bottom of installation base plate 1, and rail 51 is arranged at the other side of installation base plate 1, a sliding block is arranged on rail 51, one end of Y adjusting cylinder 6 is arranged on the sliding block, and the other end of Y adjusting cylinder 6 is connected with X adjusting cylinder 5. When X adjusting cylinder 5 works, Y adjusting cylinder 6 realizes reciprocation on rail 51. In the embodiment, Y adjusting cylinder 6 is a bidirectional adjusting cylinder, and can also be a unidirectional adjusting cylinder, which is arranged according to actual needs.

[0020] To assist in detecting the bogie after maintenance, sensor monitoring assembly is connected to displacement adjusting assembly through connecting rod. Specifically, upper displacement offset monitoring sensor mounting bracket 61 is arranged on the cylinder seat of Y adjusting cylinder 6, and auxiliary data monitoring sensor mounting rod 8 is arranged on one side of Y adjusting cylinder 6.
