Mine vehicle-mounted hydraulic winch

Abstract

The invention belongs to the technical field of traction equipment, and particularly relates to a mine vehicle-mounted hydraulic winch, which is matched with a mine auxiliary transporting vehicle and aims at solving the problems of the existing hydraulic winch. The mine vehicle-mounted hydraulic winch comprises a planetary speed reducer, a chain mechanism, a brake, a hydraulic motor assembly and a circular chain, wherein the planetary speed reducer, the chain mechanism, the brake and the hydraulic motor assembly are sequentially connected to form a sealed structure, and the brake is provided with disc springs and adopt the multi-disc spring dry brake and counterbalance valve brake double-action type. The mine vehicle-mounted hydraulic winch has the advantages that the mine vehicle-mounted hydraulic winch is especially suitable for auxiliary transporting equipment in coal mine wells; the structure is compact, the traction force is large, the brake is safe and reliable, and the working efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of traction equipment, and in particular relates to a mine vehicle-mounted hydraulic winch used in conjunction with mine auxiliary transport vehicles. Background technique [0002] A hydraulic winch is a winch that uses a hydraulic motor to drive the drum directly or through a gearbox. [0003] The hydraulic winch has the characteristics of lifting and traction. It is commonly used in ships, ports, construction, mining, metallurgy and other industries. As a mechanical equipment for auxiliary transportation, this kind of winch needs an independent pump station hydraulic system to provide power. Most of them adopt the drum-wound steel wire rope structure, which has simple structure, inflexible operation mode, fixed use location, and inconvenient transportation of materials or mechanical equipment; thirdly, the underground working environment is relatively harsh, and external pollution or impact can easily caus...

Problems solved by technology

[0003] The hydraulic winch has the characteristics of lifting and traction. It is commonly used in ships, ports, construction, mining, metallurgy and other industries. As a mechanical equipment for auxiliary transportation, this kind of winch needs an independent pump station hydraulic system to provide power. Most of them adopt the drum-wound steel wire rope structure, which has simple structure, inflexible operation mode, fixed use location, and inconvenient transportation of materials or mechanical equipment; thirdly, the underground working environment is relatively harsh, and external pollution or impact can easily cause damage to the winch , which affects production efficiency; and the existing winch is generally an open structure with a large volume, which brings a lot of inconvenience to underground use

If it is to be used on vehicles, there is no suitable product in China. Because there are often accelerations or sudden brakes during the transportation of heavy objects on the vehicle, this puts forward very strict requirements on the braking effect of the winch, so that it can withstand more Large shock and vibration, to avoid the danger of winch brake failure
