Endless rope speed regulation mechanical winch driving device used for mine

Abstract

The invention discloses an endless rope speed regulation mechanical winch driving device used for a mine, belonging to a mine transporting device which mainly serves as an underground roadway wire rope traction system. Equal-power double-speed electromotor speed regulation is used for replacing traditional mechanical speed regulation and variable frequency motor speed regulation. The speed regulation device of the invention adopts simultaneously float of high-velocity planet carrier and low-velocity sun gear; a high-speed internal gear and a low-speed internal gear are connected with a rollerinto a whole to realize power division, an electro hydraulic control system is combined for carrying out friction machinery soft start and remote operation control of the drive device. At working time, the invention can arbitrarily switch high speed and low speed without halting. The invention has the advantages of low cost, small noise, compact structure, convenient operation, safety and reliability.

Description

technical field [0001] The invention discloses a driving device of a mechanical winch with infinite rope speed regulation for mining, which belongs to special transportation equipment for coal mines. It is mainly used as the driving device of the steel wire rope traction system in the underground roadway. It can transport materials and equipment with the wire rope and other auxiliary equipment, and is especially suitable for long-distance traction and transportation of large-scale fully mechanized mining equipment. Background technique [0002] Existing various types of dispatching winches and transport winches generally have low traction force, which makes it difficult to transport large equipment underground; most winches adopt mechanical speed regulation, which are large in size, high in noise, and complex in structure. Although some winches use frequency conversion motors for speed regulation, but Its technical requirements are high, it is not convenient for underground ...

Problems solved by technology

[0002] Existing various types of dispatching winches and transport winches generally have low traction force, which makes it difficult to transport large equipment underground; most winches adopt mechanical speed regulation, which are large in size, high in noise, and complex in structure. Although some winches use frequency conversion motors for speed regulation, but Its technical requirements are high, it is not convenient for underground use and maintenance, and its production cost is high, so it cannot be widely used and promoted; the existing winches are almost without exception manual braking, which is labor-intensive and poor in safety and reliability.

The existing winch structure is difficult to meet the requirements of high power, miniaturization, and high safety. Due to the particularity of underground production conditions in coal mines, there are problems such as restrictions on going into the mine and difficulties in installation.
