Problems solved by technology

[0003] Due to the complex environment in the mine, occasionally falling stones or other sundries will get stuck between the balance rope and the guide wheel, which will cause a false phenomenon of "balance rope jumping". , It will also cause the balance rope and the anti-jump rod to be stuck, thereby affecting the normal operation of the lifting system, and may cause accidents and cause unnecessary losses. In addition, the maintenance of this kind of balance rope stuck is time-consuming and laborious. very inconvenient

Embodiment 1

[0058] The flexible cable adaptive guide wheel of this embodiment includes,

[0059] The guide wheel main body 1 has guide wheel side plates 10 formed on both sides thereof;

[0060] Guide wheel support 2, it is connected with guide wheel main body 1 by guide wheel axle 20;

[0061] The anti-job-hopping rod 3 is connected to the guide wheel bracket 2 at its end, and the anti-job-hopping rod 3 is horizontal to the guide wheel shaft 20 and placed in front of the guide wheel main body 1;

[0062] Also includes:

[0063] Liner 4, which surrounds the wheel surface of the guide wheel main body 1, the distance between the liner 4 and the axis of the guide wheel main body 1 is variable;

[0064] The distance from the outer edge of the guide wheel support 2 to the axis of the guide wheel main body 1 is greater than the maximum distance from the outer edge of the pad 4 to the axis of the guide wheel main body 1 .

[0065] In the existing guide wheel structure, the guide wheel main bo...

Embodiment 2

[0068] The cable adaptive guide wheel of this embodiment is further improved on the basis of embodiment 1, and further includes an elastic mechanism 5 through which the pad 4 is connected to the wheel surface of the guide wheel main body 1 .

[0069] The variable function of the distance between the liner 4 and the axis center of the guide wheel main body 1 is realized by the elastic mechanism 5. The elastic mechanism 5 described in this application includes but is not limited to structures such as rubber, springs, and dampers with deformation recovery properties. Realize that the liner 4 moves toward the axis of the guide wheel main body 1 after being stressed, and the member that restores the position of the liner 4 after releasing the force can be used as the elastic mechanism 5 to connect the liner 4 with the wheel surface of the guide wheel main body 1.

Embodiment 3

[0071] The flexible cable adaptive guide wheel of this embodiment is further improved on the basis of embodiment 2. The elastic mechanism 5 is an annular honeycomb rubber structure, which is formed around the wheel surface of the guide wheel main body 1, and the liner 4 The ring is connected to the outer edge of the annular honeycomb rubber structure.

[0072] This embodiment shows a structural form of the elastic mechanism 5, such as figure 2 As shown, the elastic mechanism 5 is annular rubber, which is sleeved on the wheel surface of the guide wheel main body 1. The interior of the annular rubber is honeycomb-shaped, and the gasket 4 is fixed on the outer edge surface of the annular rubber. When debris falls into the balance rope When it is in the guide wheel, during the movement of the balance rope, the debris acts on the liner 4 in contact with it, and the force on the liner 4 makes the ring-shaped rubber part connected to it deform, so that the liner 4 moves closer to th...

Abstract

The invention discloses a cable self-adaptive guide wheel and a guide method thereof, belonging to the technical field of mine hoisting. The guide wheel includes: the guide wheel main body, with guide wheel side plates formed on both sides; the guide wheel bracket, which is connected to the guide wheel main body through the guide wheel shaft; The wheel shaft is horizontal and placed in front of the main body of the guide wheel; it also includes a liner, which surrounds the wheel surface of the main body of the guide wheel, and the distance between the liner and the axis of the main body of the guide wheel is variable; the outer edge of the guide wheel bracket to the axis of the main body of the guide wheel The distance is greater than the maximum distance from the outer edge of the liner to the axis of the main body of the guide wheel. The guide wheel of the present invention improves the structure of the balance rope guide wheel, and when debris falls into it, the distance from the liner to the main axis of the guide wheel changes, so that there is enough clearance between the balance rope and the anti-jump bar to allow the balance rope to work normally. Pass to ensure the smooth operation of the lifting system.

Description

technical field [0001] The invention belongs to the technical field of mine hoisting, and more specifically relates to a cable self-adaptive guide wheel and a guide method thereof. Background technique [0002] In mine hoisting systems, mining elevators and other hoisting systems, there are multiple balance ropes at the bottom of the hoisting container to ensure the smooth operation of the entire hoisting system. An adaptive balance rope guide system is installed at the bottom of the system. In this system, in order to prevent the balance rope from jumping, an anti-jump bar is often installed under the balance rope guide wheel to ensure the safe operation of the system. [0003] Due to the complex environment in the mine, occasionally falling stones or other sundries will get stuck between the balance rope and the guide wheel, which will cause a false phenomenon of "balance rope jumping". , It will also cause the balance rope and the anti-jump rod to be stuck, thereby affec...
