Problems solved by technology
The weight of the former balance wheel increases the weight of the lifting container, and when the diameter of the balance wheel is small, the small deflection radius of the wire rope will directly affect its actual service life
The latter takes up a lot of space on the derrick, and the compensation length of the steel wire rope has certain limitations. At present, this method is often used abroad to balance the tension between the steel wire ropes.

The invention belongs to the technical field of mine hoist, in particular to a compound bevel gear balance device for tension of steel wire ropes of a three-rope winding type mine hoist. The compound bevel gear balance device comprises a housing, wherein a supporting frame is fixedly arranged in the housing; the supporting frame comprises a hollow hub; the outer surface of the hollow hub is uniformly distributed with cylinders in the radial direction; a compound balance bevel gear is separately arranged on each cylinder; and each compound balance bevel gear is composed of a large balance bevel gear and a small balance bevel gear, and the large balance bevel gear and the small balance bevel gear have the same number of teeth, and can synchronously and freely rotate around the corresponding cylinder, the large balance bevel gear is engaged with a large output bevel gear with a connecting flange, and the small balance bevel gear is engaged with a small output bevel gear with a connecting flange. The compound bevel gear balance device for tension of steel wire ropes of the three-rope winding type mine hoist has the characteristic of being mounted on a main shaft, simple in structure, convenient to maintain, free of any limitation on length compensation of three steel wire ropes, and capable of precisely balancing tension of the three steel wire ropes.
Description
technical field [0001] The invention belongs to the technical field of mine hoists, and in particular relates to a three-rope winding type mine hoist wire rope tension composite bevel gear balancing device. Background technique [0002] At present, mine hoists are mainly divided into two categories: single-rope winding hoists and multi-rope friction hoists. For single-rope winding hoists, in the process of use in deep wells and large terminal load conditions, due to the influence of large loads and the weight of the wire rope, it is often necessary to choose an excessively large diameter of the wire rope, and the diameter of the drum is correspondingly large. The steel wire rope and the diameter of the drum will bring a lot of inconvenience to manufacture and use, which limits the further use of the single-rope winding hoist in deep wells to a certain extent; It solves the problem of deep well hoisting, but because this type of hoist must add a balance tail rope during use,...
