Description

Technical Field

[0001] The invention relates to the technical field of rail vehicles, and in particular to a hoisting tool used for turning over a frame of a rail engineering vehicle. Background Art

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

[0003] At present, during the assembly and processing of rail vehicles, a flipping device is needed to flip the rail vehicle frame for assembly and maintenance.

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

[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. Summary of the invention

[0006] The invention provides a hoisting tool for turning over a frame of a rail engineering vehicle, which solves the problems of reducing the service life of a steel wire rope and posing potential safety hazards.

[0007] In order to solve the above technical problems, the present invention provides a hoisting tool for turning over a frame of a railway engineering vehicle, comprising:

[0008] Rib;

[0009] A bent plate, the bent plate being arranged on the inner side surface of the rib plate;

[0010] A pin shaft, wherein the pin shaft is arranged inside the bent plate;

[0011] A cotter pin, the cotter pin being arranged inside one end of the pin shaft;

[0012] The latch is arranged inside the rib plate, the outer side surface of the latch is sleeved with a shackle, and the outer side surface of the shackle is sleeved with a wire rope.

[0013] Preferably, the cotter pin is arranged on the top of the bent plate.

[0014] Preferably, the outer side surface of the pin is threadedly connected with a nut, and the nut is arranged on one side of the shackle.

[0015] Preferably, a positioning groove is provided inside the bent plate, and a positioning plate is fixedly mounted on one side of the rib plate close to the bent plate.

[0016] Preferably, the positioning plate is clamped to the inner side of the positioning groove.

[0017] Preferably, side panels are fixedly mounted on both sides of the top and bottom of the rib plate, and positioning screws are arranged inside the side panels.

[0018] Preferably, one end of the positioning screw is threadedly connected to the inside of the bent plate.

[0019] Compared with the related art, the hoisting tool for turning over the frame of a rail engineering vehicle provided by the present invention has the following beneficial effects:

[0020] The present invention provides a lifting tool for flipping a frame of a rail engineering vehicle. The lifting tool cooperates with each other through structures such as a rib plate, a latch, a nut, a cotter pin, a bent plate, a pin shaft, a shackle and a wire rope. When in use, the bent plate is sleeved on the outer side surface of the frame, and the pin shaft is inserted into the interior of the bent plate. Then, the cotter pin is inserted into the interior of the pin shaft, so that the bent plate is limited to the outer side surface of the frame. Then, the wire rope is inserted into the interior of the shackle and connected to the overhead crane. In this way, it is possible to avoid directly sleeved the wire rope on the outer side surface of the frame, thereby avoiding direct friction between the wire rope and the frame, which not only increases the service life of the wire rope, but also increases safety.

[0043] Second embodiment

[0044] Please refer to Figure 4 and Figure 5 Based on the first embodiment of the present application, a lifting tool for turning over the frame of a railway engineering vehicle is provided. The second embodiment of the present application proposes another lifting tool for turning over the frame of a railway engineering vehicle. The second embodiment is only 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 opened 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 clamped on the inner side surface of the positioning groove 71 .

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

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

[0049] When installing between the rib plate 1 and the bent plate 3 , the positioning plate 7 is first inserted 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 a lifting tool for turning over a frame of a rail engineering vehicle provided by the present invention 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 connection 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, disassemble the bent plate 3 and the rib plate 1, and then replace the damaged parts, 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 inside 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 position between the replaced rib plate 1 and the bent plate 3.

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

[0054] By cooperating with each other through the positioning plate 7, the positioning groove 71, the side plate 8 and the 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.

[0055] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
