Based on the embodiment in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] The following will combine Figure 1 to describe the mine car tipping device of the utility model.

[0024] As Figure 1 shown, in the embodiment of the utility model, the mine car tipping device comprises: frame body 1, first telescopic piece 2, clamping plate 3 and second telescopic piece 4. The first telescopic piece 2 is rotationally connected with the frame body 1, the clamping plate 3 is connected with the first telescopic piece 2, and the first telescopic piece 2 can drive the clamping plate 3 to move when being elongated to be connected with the edge of the bucket 200 of the mine car 100. The second telescopic piece 4 is connected with the first telescopic piece 2, and the second telescopic piece 4 can drive the first telescopic piece 2 and the clamping plate 3 to rotate when being telescoped to overturn the bucket 200.

[0025] Specifically, the mine car 100 travels along the track, the bucket 200 is placed on the mine car 100, and the bucket 200 is filled with coal. The frame body 1 is arranged at a dumping point. When the mine car 100 travels to the vicinity of the frame body 1, the first telescopic member 2 is elongated to drive the clamping plate 3 to move, and the clamping plate 3 is clamped with the edge of the bucket 200. The second telescopic member 4 can be directly connected with the first telescopic member 2, or connected with the first telescopic member 2 through other connecting members. When the second telescopic member 4 is telescoped, the first telescopic member 2 and the clamping plate 3 are driven to rotate, and the clamping plate 3 is turned over when rotating to overturn the bucket 200.

[0026] In the embodiment, the first telescopic member 2 and the second telescopic member 4 can be oil cylinders, air cylinders or electric cylinders. The cylinder body of the first telescopic member 2 is rotationally connected with the frame body 1, and the telescopic rod of the first telescopic member 2 is connected with the clamping plate 3. The telescopic rod of the second telescopic member 4 is connected with the cylinder body of the first telescopic member 2, and the second telescopic member 4 can drive the cylinder body of the first telescopic member 2 to rotate when telescoping. Further, according to different installation positions of the second telescopic member 4, the second telescopic member 4 can drive the first telescopic member 2 to rotate when elongating, or can drive the first telescopic member 2 to rotate when contracting.

[0027] The mine car tipping device provided by the embodiment of the utility model can clamp the bucket when the mine car travels to the dumping point, and automatically overturn the bucket to dump the coal, without the need of multiple people to overturn the bucket, so that the labor cost is reduced, and the safety of operation is improved.

[0028] As shown in the drawings, Figure 1 In the embodiment of the utility model, the first end of the clamping plate 3 is connected with the first telescopic member 2, and the second end of the clamping plate 3 is provided with a groove 31, which can be clamped with the edge of the bucket 200 when the first telescopic member 2 is elongated.

[0029] As shown in the drawings, Figure 1 In the embodiment of the utility model, the mine car tipping device further comprises a proximity switch 5 and a sensing block 6. The proximity switch 5 is arranged on the frame body 1, and the sensing block 6 is arranged on the mine car 100. When the mine car 100 travels to the position where the sensing block 6 is opposite to the proximity switch 5, the proximity switch 5 sends an alarm, and the operator starts the first telescopic member 2 to elongate, so that the clamping plate 3 is clamped with the bucket 200.

[0030] Further, the first telescopic member 2 can also be automatically elongated. Specifically, the mine car tipping device further comprises a controller. When the sensing block 6 is opposite to the proximity switch 5, the proximity switch 5 sends a first signal to the controller, and the controller controls the first telescopic member 2 to elongate after receiving the first signal, so that the clamping plate 3 is clamped with the edge of the bucket 200.

[0031] The operator can observe by naked eyes that after the clamping plate 3 is clamped with the bucket 200, the second telescopic piece 4 is started. When the second telescopic piece 4 is telescoped, the clamping plate 3 is driven to rotate, and then the bucket 200 is overturned. Alternatively, in order to reduce the labor intensity of the operator, the mine car tipping device further comprises a laser range finder. The laser range finder is arranged on the clamping plate 3, and the laser range finder is used for detecting the distance between the clamping plate 3 and the bucket 200. When the clamping plate 3 is clamped with the bucket 200, the laser range finder sends an alarm, the operator starts the second telescopic piece 4, and the second telescopic piece 4 is telescoped to drive the clamping plate 3 to rotate.

[0032] Further, the laser range finder can also send a second signal to the controller when the clamping plate 3 is clamped with the bucket 200, and the controller controls the second telescopic piece 4 to telescope after receiving the second signal, thereby driving the clamping plate 3 to rotate.

[0033] In this way, automatic tipping can be realized, and the whole tipping process does not need manual participation. When the inductive block 6 is opposite to the proximity switch 5, the first telescopic piece 2 is elongated to drive the clamping plate 3 to move. When the clamping plate 3 is clamped with the bucket 200, the second telescopic piece 4 is telescoped to drive the clamping plate 3 to rotate, and then the bucket 200 is overturned.

[0034] In the above embodiment, the laser range finder is used for detecting the distance between the end of the clamping plate 3 and the edge of the bucket 200. When the distance between the two is equal to 0, it indicates that the clamping plate 3 is in abutment with the edge of the bucket 200. At this time, the laser range finder sends a second signal to the controller. In actual operation, the controller controlling the second telescopic piece 4 to telescope can be set as delay control, that is, after the controller receives the second signal sent by the laser range finder, the second telescopic piece 4 is controlled to telescope after several seconds, so that the first telescopic piece 2 can continue to drive the clamping plate 3 to move, increase the clamping amount of the clamping plate 3 and the bucket 200, and improve the firmness of the clamping of the two, and then drive the clamping plate 3 to rotate, so as to avoid that the clamping amount is too small, the clamping plate 3 is separated from the bucket 200 when rotating, and thus the bucket 200 cannot be overturned.

[0035] As shown in FIG. 1, Figure 1 In the embodiment of the utility model, the mine car tipping device further comprises a traction rope 7, and two ends of the traction rope 7 are connected with the first telescopic piece 2 and the second telescopic piece 4 respectively. Specifically, the connection between the first telescopic piece 2 and the second telescopic piece 4 can be realized through the traction rope 7. When the second telescopic piece 4 is telescoped, the traction rope 7 is driven to move, and then the first telescopic piece 2 is driven to rotate.
