A new type of gear transmission tension balance multi-rope winding mine hoist

Abstract

The invention provides a novel gear drive tension balance multi-rope winding type mine hoist, and belongs to the technical field of mine hoists. The novel gear drive tension balance multi-rope winding type mine hoist mainly solves problems in tension balance of hoisting ropes. The novel gear drive tension balance multi-rope winding type mine hoist comprises two main shaft devices and a gear drive system which connects the two main shaft devices together, and is characterized in that the first main shaft device is connected with the second main shaft device through the gear drive system, main shaft device gear drive type tension balance devices are used for achieving the tension balance of the hoisting ropes, each main shaft device gear drive type tension balance device comprises a housing, a support frame fixedly connected with each main shaft, a left output bevel gear connected with each main shaft in sliding mode, a right output bevel gear connected with each main shaft in sliding mode, an upper balance bevel gear connected with the support frame in sliding mode and a lower balance bevel gear connected with the support frame in sliding mode, each upper balance bevel gear and each lower balance bevel gear are both meshed with each left output bevel gear and each right output bevel gear, and each housing is connected with each support frame, each left output bevel gear and each right output bevel gear in sliding mode.

Description

technical field [0001] The invention belongs to the technical field of mine hoists, and in particular relates to a novel gear transmission tension balance multi-rope winding type mine hoist. Background technique [0002] At present, domestic mining enterprises mainly use two types of mine hoists: one is the single-rope winding hoist. The diameter of the steel wire rope is often required to be very large, and the corresponding drum diameter is also required to be large, and the excessively large diameter of the steel wire rope and the excessively large drum diameter are inconvenient in the manufacture and use of the steel wire rope and the drum, which limits them to a certain extent. The use of single-rope winding hoists in deep well conditions; the other type is multi-rope friction hoists. This type of hoist solves the problem of deep well hoisting to a certain extent due to the use of multi-ropes, but due to this type of hoisting The machine must be equipped with a balance...

AI Technical Summary

Problems solved by technology

In foreign countries, the multi-rope winding hoist is used for ultra-deep well hoisting. The wire rope tension balance device mostly adopts the balance wheel directly installed on the coupling device or the sky mounted on the derrick with two interconnected hydraulic cylinder pistons. The disadvantage of the former is that the weight of the balance wheel is large, which increases the weight of the lifting container. When the diameter of the balance wheel is small, the service life of the wire rope will be affected due to the small deflection radius of the wire rope.

The latter occupies a large space in the derrick, and the compensation length of the wire rope is limited to a certain extent.
