[0002] In mine production, mine hoists are crucial pieces of equipment used to lift materials such as coal and ore, as well as personnel and equipment. The skip, as a vital load-bearing component of the hoist, directly impacts hoisting efficiency and operational safety through its operational stability. Typically, guide wheels are installed on one side of the skip during operation, allowing it to move stably along the track.

[0003] However, the guide wheels of mine hoist skips commonly suffer from runout. Runout of the guide wheels can cause many problems: on the one hand, it affects the normal operating trajectory of the skip and reduces hoisting efficiency; on the other hand, runout increases friction between the guide wheels and the track, accelerates equipment wear, and shortens the service life of the guide wheels and the track; in severe cases, it may even lead to safety accidents such as skip jamming or derailment.

[0004] Therefore, it is necessary to provide a new anti-sway device for the skip guide wheel of a mine hoist to solve the above-mentioned technical problems. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1-8 The anti-sway device for the skip guide wheel of a mine hoist includes: two drive shafts 1, with the same drive belt 2 mounted on both drive shafts 1; a connecting seat 3 is fixedly installed on the drive belt 2; a skip 4 is fixedly installed on one side of the connecting seat 3; an outer guide ring 5 is provided on one side of the drive belt 2; a first inner guide ring 7 and a second inner guide ring 8 are provided inside the outer guide ring 5; three positioning plates 6 are fixedly installed on the inner walls of the first inner guide ring 7 and the second inner guide ring 8; multiple stabilizing strips 9 are fixedly installed on one side of the first inner guide ring 7; and the outer guide ring 5 is fixedly connected to the multiple stabilizing strips 9. In actual use, the positioning plates 6 are aligned with the inner wall of the hoist casing. The outer guide ring 5, the first inner guide ring 7, and the second inner guide ring 8 are fixedly connected to form a stable connection. A connecting lever 13 is detachably installed on one side of the connecting seat 3. A guide wheel 15 is fixedly installed on the connecting lever 13. The guide wheel 15 is tangent to the inner wall of the outer guide ring 5 and also tangent to the outer walls of the first inner guide ring 7 and the second inner guide ring 8, thereby forming a guiding effect. An anti-deviation block 17 is detachably installed on one side of the guide wheel 15. The anti-deviation block 17 contacts the side of the first inner guide ring 7 and the second inner guide ring 8 that are close to each other, so that the guide wheel 15 can form a stable anti-deviation effect.

[0025] In the above method, a first slot 11 is provided on one side of the connecting seat 3, and a plug block 12 is provided inside. One side of the plug block 12 is fixedly connected to the connecting folding rod 13. A first through hole is provided on the connecting seat 3, and a second through hole is provided on the plug block 12. The first through hole and the second through hole are connected. The same fastening screw 14 is provided in the first through hole and the second through hole. A locking nut is threaded on the fastening screw 14. The top of the locking nut abuts against the bottom of the connecting seat 3, and the screw head of the fastening screw 14 abuts against the top of the connecting seat 3, thereby forming a stable installation and also achieving a detachable effect, which facilitates the replacement of the guide wheel 15 later.

[0026] In this method, in order to quickly replace the severely worn anti-deviation block 17 during subsequent use, a second slot 16 is provided on the side of the guide wheel 15 away from the connecting seat 3. One side of the anti-deviation block 17 is inserted into the second slot 16, and a groove 18 is provided on the side of the anti-deviation block 17 away from the connecting seat 3. A threaded hole is provided in the second slot 16, and a bolt 19 is provided in the groove 18. One end of the bolt 19 extends into the threaded hole and is screwed into the inner wall of the threaded hole.

[0027] In this method, in order to ensure that the anti-deviation block 17 slides smoothly without causing interference, two clearance slots 10 are provided on each of the three positioning plates 6. The anti-deviation block 17 is adapted to the clearance slots 10, and the anti-deviation block 17 can pass through the clearance slots 10 to achieve stable movement.

[0028] The working principle of the anti-sway device for the skip guide wheel of the mine hoist provided by this utility model is as follows:

[0029] In this utility model, only one set of connecting seat 3 and bucket 4 is shown. In actual use, multiple sets of connecting seat 3 and bucket 4 can be set for use.

[0030] When the drive shaft 1 rotates and drives the drive belt 2, the connecting seat 3 moves the skip 4, thus forming a lifting action;

[0031] During the movement of the skip 4, the guide wheel 15 can provide precise guidance to prevent the transmission belt 2 from causing the skip 4 to deviate. Furthermore, the guide wheel 15 itself is limited by the anti-deviation block 17, which can basically avoid the occurrence of swaying. The anti-deviation block 17 moves along a specific route in the space between the first inner guide ring 7 and the second inner guide ring 8, thereby achieving a good anti-deviation effect.

[0032] In subsequent use, when the anti-deviation block 17 is severely worn and needs to be replaced, simply unscrew the bolt 19 in the recess 18 to remove the anti-deviation block 17 directly, then insert the new anti-deviation block 17 into the second slot 16, and then tighten the bolt 19 again. Furthermore, when the guide wheel 15 is severely worn and needs to be replaced, first unscrew the anti-deviation block 17 as described above, then unscrew the fastening screw 14 from the connecting seat 3, and then directly pull out the connecting rod 13 along with the guide wheel 15. Then, insert the plug block 12 on the new connecting rod 13 into the first slot 11 and secure it with the fastening screw 14. At this time, the guide wheel 15 is also placed between the outer guide ring 5 and the first inner guide ring 7. Afterwards, reinstall the anti-deviation block 17, and it can continue to be used.

[0033] Compared with related technologies, the anti-sway device for the guide wheel of the mine hoist skip provided by this utility model has the following beneficial effects:

[0034] This utility model provides a device for preventing swaying of the guide wheel of a mine hoist skip. The outer guide ring 5, the first inner guide ring 7 and the second inner guide ring 8, and the guide wheel 15 set between the outer guide ring 5 and the first inner guide ring 7 can guide the skip 4. Then, the anti-sway block 17 set between the first inner guide ring 7 and the second inner guide ring 8 can prevent the guide wheel 15 from swaying, thereby reducing the wear on the guide wheel 15, extending its service life, and preventing dangerous situations such as derailment and jamming, thus improving the safety performance.
