As shown in fig. 1 to 4, the present utility model provides a technical solution: a special lifting appliance for a diesel locomotive tyre comprises the following components:

the clamping base 2 is oriented on one side towards the diesel locomotive tyre.

As shown in fig. 3, the chucking substrate 2 includes: a base plate 202 having one side facing the diesel locomotive tire; in this embodiment, the outline of the base plate 202 is square, and rounded corners are formed at the four corners, so as to avoid injuring staff when not in use. A chute 201 which is uniformly distributed on the surface of the base plate 202 and penetrates the base plate 202; and is rotationally connected with the base plate 202 and used for driving the clamping device 1 to move; in this embodiment, when the hub of the diesel locomotive is clamped, the rotating shaft 206 is generally contacted with one end of the bearing of the hub of the diesel locomotive, so that the rotating shaft 206 is smoother, and even the balls are arranged, so that the hub can still flexibly rotate when being abutted.

A rotating column 204, which is clamped with the rotating shaft 206, and is used for driving the rotating shaft 206 to rotate; in this embodiment, an engaging block 205 is disposed at an end of the rotating post 204 to be engaged with the rotating shaft 206, and a slot corresponding to the engaging block 205 is disposed at a corresponding end of the rotating shaft 206, so that the rotating post 204 can drive the rotating shaft 206 to rotate after being inserted into the rotating shaft 206. A lifting ring 203 is disposed at an end of the rotation column 204 away from the clamping device 1, for pulling the diesel locomotive tire by an external driving source through a lifting appliance. The external driving source may be a conventional crane or the like, and is connected to the suspension ring 203 after clamping.

The clamping device 1 can slide on the clamping base 2 so as to clamp the diesel locomotive tyre facing the clamping base 2 and pull out the diesel locomotive tyre in the opposite direction of the diesel locomotive under the action of external force.

As shown in fig. 2, the clamping device 1 includes: the rotating disc 103 is fixedly connected with the rotating shaft 206 at the center thereof and can rotate along with the rotation of the rotating shaft 206; in this embodiment, the rotating disc 103 also presents a square shape, and the curved bars 105 are uniformly and rotatably connected with the rotating disc 103, and each sliding groove 201 corresponds to one another, and each curved bar 105 extends along one end of the rotating disc 103 into a space surrounded by two inner side extension surfaces of the corresponding sliding groove 201; in this embodiment, the curved bars 105 are disposed exactly at the four corners of the rotating disc 103, and the curved directions of the four curved bars 105 are identical, exactly enclosing a circle around the rotating shaft 206.

The sliding blocks 104 are in one-to-one correspondence with the curved bars 105, are respectively and rotatably connected with one end of the corresponding curved bar 105 far away from the rotating disc 103, and extend to the opposite side of the rotating disc 103 through the corresponding sliding grooves 201, and are used for sliding along the sliding grooves 201. Thus, in this embodiment, when the engagement of the crank 105 and the rotating disk 103 is aligned with the slide slot 201, the slider 104 is located furthest from the center of the base disk 202, and as the rotating disk 103 rotates, the slider 104 is caused to converge toward the center and always slide along the slide slot 201.

The clamping seats 102 are in one-to-one correspondence with the sliding blocks 104, are positioned on one side of the base plate 202 facing the diesel locomotive tyre, and are fixedly connected with the corresponding sliding blocks 104; the clamping blocks 101 are in one-to-one correspondence with the clamping seats 102 and are clamped with the corresponding clamping seats 102, so as to clamp the tire of the diesel locomotive. In this embodiment, the clamping blocks 101 with corresponding sizes are replaced according to the positions of the tires of the internal combustion engine, so that the clamping blocks 101 can be stably clamped with the tires of the internal combustion engine.

And an orientation device 3 provided on the opposite side of the grip base 2 to the side of the tire of the diesel locomotive for ensuring that the grip device 1 slides in a fixed direction.

As shown in fig. 4, the orientation apparatus 3 includes: a rotating seat 303, connected to one of the sliders 104, for supporting the orienting device 3;

the slide bar 302 has one end connected to one end of the rotating base 303 and the other end connected to the base plate 202 via the connecting post 301. Since the slide bar 302 is fixed, the direction of extension and contraction is also fixed, so that the sliding direction of the corresponding slide block 104 can be limited, and the slide block 104 is prevented from falling out of the slide rail, and because of the linkage relationship between the slide blocks 104, one slide block 104 is limited, and the limiting effect on other slide blocks 104 is also achieved.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made hereto without departing from the spirit and scope of the utility model as defined by the appended embodiments and equivalents thereof.
