[0002] Railcars are the main means of transportation for railway equipment maintenance, overhaul, infrastructure and other construction departments to carry out their tasks. Railcars are divided into heavy and light types. Those that can be evacuated from the line by passengers at any time are called light railcars; those that cannot be evacuated from the line by passengers at any time are called heavy railcars.

[0003] Currently, when assembling and processing rail cars, a flipping device is needed to flip the rail car frame for assembly and maintenance.

[0004] Existing flipping devices mostly use steel wire ropes to connect the frame. When the frame flips, two overhead cranes lift the steel wire ropes, and the steel wire ropes are directly wrapped around the frame. Due to the sharp corners of the frame steel structure, the steel wire ropes may be cut, affecting the service life of the steel wire ropes and posing a major safety hazard.

[0005] Therefore, it is necessary to provide a lifting tool for turning over the frame of a rail engineering vehicle to solve the above technical problems. Utility Model Content

[0044] Please refer to Figure 4 and Figure 5 Based on the first embodiment of this application, which provides a lifting fixture for flipping a railway construction vehicle frame, the second embodiment of this application provides another lifting fixture for flipping a railway construction vehicle frame. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0045] Specifically, the second embodiment of the present application provides a lifting fixture for flipping the frame of a rail engineering vehicle. The difference is that, in the lifting fixture for flipping the frame of a rail engineering vehicle, a positioning groove 71 is provided inside the bent plate 3, and a positioning plate 7 is fixedly installed on one side of the rib plate 1 close to the bent plate 3.

[0046] The positioning plate 7 is engaged with the inner side surface of the positioning groove 71 .

[0047] Side panels 8 are fixedly mounted on both sides of the top and bottom of the rib plate 1 , and positioning screws 81 are provided inside the side panels 8 .

[0048] One end of the positioning screw 81 is threadedly connected to the interior of the bent plate 3 .

[0049] When installing between the rib plate 1 and the bent plate 3 , first insert the positioning plate 7 into the inner side of the positioning groove 71 , so that the rib plate 1 and the bent plate 3 can be limited.

[0050] The working principle of the lifting tool for turning over the frame of a railway engineering vehicle provided by the utility model is as follows:

[0051] When one of the rib plate 1 or the bent plate 31 is damaged during use, the user can rotate the positioning screw 81 to make one end of the positioning screw 81 come out from the internal thread of the bent plate 3, and then move the rib plate 1 to the side away from the bent plate 3, so that the positioning plate 7 moves out from the inner side of the positioning groove 71, and then disassemble the bent plate 3 and the rib plate 1, and then replace the damaged part, and then assemble the new parts;

[0052] During assembly, first insert the positioning plate 7 into the inner side of the positioning groove 71 to limit the position between the bent plate 3 and the rib plate 1, then rotate the positioning screw 81 so that the positioning screw 81 is threadedly connected to the inside of the side plate 8, and one end of the positioning screw 81 is threadedly connected to the inside of the bent plate 3, thereby limiting the installation between the replaced rib plate 1 and the bent plate 3.

[0053] Compared with the related art, the lifting tool for turning over the frame of a railway engineering vehicle provided by the present invention has the following beneficial effects:

[0054] By cooperating with each other through the positioning plate 7, positioning groove 71, side plate 8 and positioning screw 81, when in use, the positioning screw 81 is rotated inside the side plate 8, so that one end of the positioning screw 81 is threadedly connected inside the bent plate 3. In this way, the rib plate 1 and the bent plate 3 can be disassembled, and the damaged bent plate 3 or rib plate 1 can be replaced separately, thereby reducing the cost of use.
