Description

Technical Field

[0001] The present invention belongs to the field of automation, and in particular relates to an automatic hook-removing device and method for a mine auxiliary transport winch. Background Art

[0002] Wire ropes are commonly found in auxiliary transportation equipment in mines, particularly in inclined winches and hoists. For example, in the mine's surface square, a hook car, pulled by the winch's wire rope, is located above the inclined shaft. A locomotive pushes a material-carrying mine car through a ground-track switch and onto the inclined shaft track. Under current technology, the hook car is manually coupled to the mine car compartment, and then the winch's wire rope lowers the hook car and mine car, completing the material transfer from the mine's surface square. Similarly, the hook car and underground material car are lifted by the winch's wire rope. When they reach the designated location in the surface square, the locomotive runs through the ground-track switch and onto the inclined shaft track. The hook car is manually uncoupled from the mine car compartment and the mine car is coupled to the motor compartment. The locomotive then pulls the mine car off the surface switch, completing the return of the material from the mine's surface square.

[0003] As can be seen, the current manual unhooking method for winch wire rope-assisted transportation in inclined shafts involves hooking the winch wire rope to the mine car, which is inefficient and poses safety risks. The automated unhooking technology studied by numerous researchers still relies on a hook car, where the winch wire rope is fixed to the hook car and automated unhooking is performed at the connection between the hook car and the mine car. This method not only increases the cost of the hook car but also affects the winch's carrying capacity and automation. Achieving a "soft-hard" automated unhooking connection between the wire rope and the material mine is crucial and of great significance. Summary of the Invention

[0052] How to use the automatic hook removal device:

[0053] When hooking the mine car 3, the mine car 3 is moved so that the first hook 34 is inserted into the corresponding placement groove 13, and the first hook 34 should correspond to the through hole 14 in the placement groove 13. By starting the corresponding first cylinder 16 to control the corresponding hook locking tongue 17 to be inserted into the corresponding through hole 14, the first hook 34 is locked.

[0054] When unhooking the mine car 3 , it is only necessary to start the corresponding first cylinder 16 to control the corresponding hook locking tongue 17 to be pulled out from the corresponding through hole 14 , and the first hook 34 is pulled out from the corresponding placement slot 13 by moving the mine car 3 .

[0055] When hooking the second hook 7, the two brush strips 53 are controlled to move away from each other by extending the second cylinder 527, and the second hook 7 is placed between the two brush strips 53. The bristles 58 are made to touch the ground by contracting the third cylinder 56. The two brush strips 53 are controlled to move closer to each other by contracting the second cylinder 527, and the second hook 7 is gathered between the placement groove 13 and the first push plate 519. The first push plate 519 is controlled to move toward the side close to the vertical plate 515 by contracting the fourth cylinder 522. The first push plate 519 is controlled to move toward the side close to the placement groove 13 by starting the first motor 510. During the movement, the horizontal plate 516 pushes the second hook 7 to move at the same time. After the second hook 7 contacts the baffle 539, the baffle Under the obstruction of 539, the second hook 7 is shoveled in above the horizontal plate 516, and the horizontal plate 516 is lifted by starting the corresponding third cylinder 56 to be flush with the lower surface of the placement groove 13. By extending the fourth cylinder 522, under the action of the third spring 520, the first push plate 519 pushes the second hook 7 to move to the side of the placement groove 13. After the first push plate 519 enters the placement groove 13, the first rack 532 and the second rack 537 respectively engage with the two sides of the gear 535, and finally push the second hook 7 to correspond to the through hole 14 in the placement groove 13. By starting the corresponding first cylinder 16, the corresponding hook locking tongue 17 is controlled to be inserted into the corresponding through hole 14 to achieve locking of the second hook 7.

[0056] When the second hook 7 is to be unhooked, the corresponding first cylinder 16 is simply activated to control the corresponding hook locking tongue 17 to be drawn out from the corresponding through hole 14 , and the second hook 7 is drawn out from the corresponding placement groove 13 by pulling the wire rope 6 .

[0058] The brush bar 53 is controlled to rise and fall by contracting the third cylinder 56, and the brush bar 53 is controlled to swing by extending and retracting the second cylinder 527.

9. The automatic hook-removing device for a mine auxiliary transport winch according to claim 8, characterized in that: A limiting strip (531) is fixed on one side of the first push plate (519) close to the chassis (11).

10. The method for using the automatic hook-removing device for a mine auxiliary transport winch according to claim 9, characterized in that: The method of use is as follows: When hooking the mine car (3), the mine car (3) is moved so that the first hook (34) is inserted into the corresponding placement groove (13), and the first hook (34) should correspond to the through hole (14) in the placement groove (13). The corresponding first cylinder (16) is activated to control the corresponding hook locking tongue (17) to be inserted into the corresponding through hole (14), thereby achieving locking of the first hook (34); When the mine car (3) is unhooked, it is only necessary to start the corresponding first cylinder (16) to control the corresponding hook locking tongue (17) to be drawn out from the corresponding through hole (14), and the first hook (34) is drawn out from the corresponding placement groove (13) by moving the mine car (3); When the second hook (7) is hooked, the two brush strips (53) are controlled to move away from each other by extending the second cylinder (527), and the second hook (7) is placed between the two brush strips (53). The bristles (58) are made to touch the ground by contracting the third cylinder (56). The two brush strips (53) are controlled to move closer to each other by contracting the second cylinder (527), and the second hook (7) is gathered between the placement groove (13) and the first push plate (519). The first push plate (519) is controlled to move toward the side close to the vertical plate (515) by contracting the fourth cylinder (522). The first push plate (519) is controlled to move toward the side close to the placement groove (13) by starting the first motor (510). During the movement, the horizontal plate (516) pushes the second hook (7) to move at the same time. After the second hook (7) contacts the baffle (539), the baffle (5 39), the second hook (7) is shoveled into the top of the horizontal plate (516), and the horizontal plate (516) is lifted by starting the corresponding third cylinder (56) to be flush with the lower surface of the placement groove (13). By starting the extended first motor (510), under the action of the third spring (520), the first push plate (519) pushes the second hook (7) to move to one side of the placement groove (13). After the first push plate (519) enters the placement groove (13), the first rack (532) and the second rack (537) are respectively engaged with the two sides of the gear (535), and finally the second hook (7) is pushed to correspond to the through hole (14) in the placement groove (13). By starting the corresponding first cylinder (16), the corresponding hook locking tongue (17) is controlled to be inserted into the corresponding through hole (14), thereby locking the second hook (7); When the second hook (7) is to be unhooked, the corresponding first cylinder (16) is simply activated to control the corresponding hook locking tongue (17) to be drawn out from the corresponding through hole (14), and the second hook (7) is drawn out from the corresponding placement groove (13) by pulling the wire rope (6).
