Horizontal type inclined cable-tension attenuating winch

Abstract

The invention provides a horizontal type inclined cable-tension attenuating device. A pair of master / slave capstan winches provided with a plurality turns of cable races are used, a mounting axis of the slave capstan winch is inclined by a proper angle relative to the mounting axis of the master capstan winch by using a horizontal type inclined three-section split type box supporting structure to enable a cable to be level to the cable races when passing in and out of the master capstan winch and the slave capstan winch, and therefore, the cable is prevented from being bent partially; a reduction motor and a driving shaft of the master capstan winch are directly connected and mounted so that the structure is compact; by using the friction force generated between the cable and the plurality turns of cable races of the capstan winches in the rotation process of the master capstan winch, the winding and the unwinding of the cable are driven, and the tension of the cable is gradually attenuated, and therefore, the purpose of attenuating the tension of the cable is fulfilled; with the integration of a cable tension measuring device, a manual friction emergency brake device and a safety pin device in the winch, the working safety and reliability are enhanced; and the winch is beneficial to the winding-unwinding driving of a special bearing cable.

Description

technical field [0001] The invention relates to a winch, in particular to a horizontal inclined cable tension attenuation winch based on a cable integrating load bearing, power transmission and communication. Background technique [0002] Ordinary hoists generally use steel wire ropes to lift the load, and the cables are wound on the winch in multiple layers. The winch cable drum is not only a driving device, but also a cable storage device. Due to the load on the cables, there is an extrusion force between the cables. When the cables are not tightly arranged, the upper layer cables will be embedded in the lower layer, making the cables easily damaged by extrusion. Especially when the cable is a cable or a composite cable (the load-bearing cable is combined with the cable), since the skin is made of plastic or rubber material, it is easily damaged by extrusion. Therefore, in order to improve the service life and operational reliability of the cable, it is necessary to separ...

AI Technical Summary

Problems solved by technology

The two-wheel vertical arrangement occupies a small area, but the height increases and the center of gravity increases, especially when the environment is limited. When the cable enters the rear wheel, the cable will rub against the front wheel and damage the cable

Therefore, it is a reasonable structural form for the two wheels to be arranged horizontally and obliquely, that is, to properly raise the front wheels to avoid friction between the cables and the front wheels. The front and rear wheel rope grooves are aligned, and the axis of the rear wheel must be inclined at a small angle relative to the axis of the front wheel, so that the winch box cannot adopt a split structure along the axis of the two wheels

In addition, the cable tension attenuation device is driven by the friction between the cable and the rope groove. Once the driving device (motor or hydraulic motor) fails or the braking force is insufficient when retracting or carrying the load, it will cause slippage. Therefore, in important applications (such as the objects attached to the cable are very valuable), safety protection measures must be provided and monitoring of the cable tension must be provided
