Endless rope continuous tractor double-rope horizontal hydraulic tensioning device

Abstract

The invention discloses an endless rope continuous tractor double-rope horizontal hydraulic tensioning device. The device comprises a rack. A main rope outgoing and winding pulley, a main rope ingoing and winding pulley and a main rope tensioning pulley are arranged on the rack. A main rope tensioning pulley is mounted between the main rope outgoing and winding pulley and the main rope ingoing and winding pulley. The main rope outgoing and winding pulley and the main rope ingoing and winding pulley are mounted on the rack. An auxiliary rope outgoing and winding pulley, an auxiliary rope ingoing and winding pulley and an auxiliary rope tensioning pulley are mounted below the main rope tensioning pulley. The auxiliary rope tensioning pulley is mounted between the auxiliary rope outgoing and winding pulley and the auxiliary rope ingoing and winding pulley. The device has following beneficial effects that the horizontal hydraulic tensioning device is simple in structure, wide in applicability to roadways and applicable to the conditions of short roadways; a horizontal mounting mode is adopted, installation, debugging and maintenance are more convenient, and the failure rate is low; by means of the horizontal mounting mode, the number of buckling points of steel wire ropes is little, winding and oversize buckling are avoided, the probability of wire fracture of the steel wire rope is reduced, and the service life of the steel wire ropes is prolonged greatly; by means of the horizontal mounting mode, the tensioning speed of the steel wire ropes is high, and the efficiency is high.

Description

technical field [0001] The invention relates to a tensioning device of an endless rope continuous tractor. Background technique [0002] As a kind of mining rail transportation equipment, endless rope continuous tractor has more advantages than winches in long-distance and large-tonnage underground transportation, and has been widely used. In order to ensure the normal operation of the continuous traction of the endless rope, the steel wire rope in the system must have a certain initial tension. Generally, a wire rope tensioning device is installed to meet the sufficient initial tension of the steel wire rope. At present, there are several types of wire rope tensioning devices for endless rope continuous tractors in the market: three-wheel heavy hammer tensioning device, five-wheel heavy hammer tensioning device, tail wheel hydraulic tensioning device and vertical tensioning device derived from heavy hammer tensioning device. Type hydraulic tensioning device, that is to rep...

AI Technical Summary

Problems solved by technology

The vertical hydraulic tensioning device overcomes the shortcomings of the heavy hammer tensioning device such as bulky size, heavy weight, and low tensioning effect, but it has an irreversible disadvantage, that is, because the hydraulic cylinder occupies a large space in the height direction, it requires a lot of manufacturing. High matching tension frame, which not only causes inconvenience to normal maintenance, but also requires high height of the roadway installed, resulting in limited installation and use, and cannot be installed in lower roadways
