Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The gangue turning equipment shown in attached figures 1 to 5 comprises an expansion link 1, a gangue turning rope 2 and a guide pulley block, wherein the expansion link 1 is fixed on a support 4 and driven to expand and contract by a driving device 5. The telescopic rod 1 can be a hydraulic oil cylinder and is driven to stretch by hydraulic pressure. The axial direction of the telescopic rod 1 is vertical to the direction of a track 7 where a gangue truck 6 is located, and the front end of the telescopic rod 1 is provided with a driven pulley 8; the telescopic direction and the concrete extending or shortening of the telescopic rod 1 are not fixed, and the reversing gangue truck 6 is related to the connection relationship between the gangue reversing rope 2 and the pulley, and the drawing 1 is only one of the embodiments. One end of the waste rock turning rope 2 is fixed on the support 4, the other end of the waste rock turning rope 2 is sequentially connected with the driven pulley 8 and the guide pulley block in a sliding manner, the other end of the waste rock turning rope penetrates through the bottom of the waste rock car 6 and is fixedly connected to the waste rock bucket 6 through the hook claw 9 to be away from one side of the telescopic rod 1, and the hook claw 9 is specifically hooked at the edge of the opening of the waste rock bucket. The telescopic rod 1 moves telescopically, and the gangue hopper is driven to overturn through the gangue turning rope 2.

The hook claw 9 is in an inverted U shape, a spherical groove 10 is formed in the tail end of the hook claw 9, and a notch of the spherical groove 10 faces the inner side of the hook claw 9; still include turning block 11, turning block 11 is including integrative laminating board 12 and the connection ball 13 that sets up, turning block 11 passes through connect ball 13 with ball type groove 10 space normal running fit. When the hook claw 9 hooks the mouth of a hopper of a waste hopper, because the waste hopper is arc, the point contact is made between the hook claw 9 and the waste hopper, the mutual friction is small, the unhooking phenomenon easily occurs, and the rotating block 11 arranged by space rotation can enable the waste hopper to incline, the attaching plate 12 always pushes against the inner side of the waste hopper, so that the hook claw 9 and the waste hopper are in surface contact by point contact thixotropy, the friction is increased, and the unhooking is prevented.

The inner side of the bent section of the U-shaped claw 9 is provided with a plurality of clamping grooves 18, so that the claw 9 is clamped with the edge of the hopper opening of the gangue hopper, the surface of the attaching plate 12 is rough, and the safety performance of the claw 9 is further improved.

The gangue dumping rope 2 is connected with at least two hooks 9, once the single hook 9 is unhooked, the gangue truck swings to injure gangue dumping workers, and the plurality of hooks 9 are not easy to unhook simultaneously to cause accidents.

One side of the track 7, which is close to the telescopic rod 1, is an inner side, and one side of the track 7, which is far away from the telescopic rod 1, is an outer side; guide pulley block includes first leading wheel 14 and second leading wheel 15, first leading wheel 14 sets up the below of telescopic link 1 is the horizontal direction with the direction of the cash rope 2 that turns over on the telescopic link 1, second leading wheel 15 sets up between two rails of track 7, and be close to the outside of track 7 will penetrate cash car 6 vehicle bottom from the outside track and turn over cash rope 2 and upwards lead to cash fill mouth department again.

A sleeve 16 is also arranged between the first guide wheel 14 and the second guide wheel 15. Because the environment situation that turns over the waste rock scene is more abominable, turns over waste rock rope 2 and directly exposes in the environment very easily just by wearing and tearing, reduces the life that turns over waste rock rope 2, also buries down the potential safety hazard, the sleeve pipe 16 cover is established turn over the waste rock rope 2 outside, can reduce the wearing and tearing that turn over waste rock rope 2 and receive, sleeve pipe 16 is provided with a plurality of observation grooves 17 along the axial direction of body, is convenient for observe the actual use condition who turns over waste rock rope 2.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
