An automatic tensioning device and control method for fully mechanized mining face

Abstract

The invention discloses an automatic tensioning device of a fully mechanized coal mining face and a control method of the automatic tensioning device. The automatic tensioning device comprises liquid draining mechanism, a liquid supplying mechanism, a control center and a tail executing mechanism. The tail executing mechanism is a component pushing a tail frame to move along a fixed sliding groove and is provided with a displacement monitoring device and a pressure monitoring device. The control center receives data of the displacement monitoring device and the pressure monitoring device and performs logical analysis and judgment on the basis of the data to control the tail executing mechanism to push the tail frame to slide finally. Fixed distance between a head frame and the tail frame is sustained, so that a scraper chain can be operated safely and reliably on the fixed distance, a transportation system of the fully mechanized coal mining face can be in stable and reliable service to production, service lives of related mechanical components like chains, chain wheels, gear sleeves and scrapers are simultaneously prolonged, operating performance and efficiency of the complete device are improved, and cost is lowered.

Description

technical field [0001] The invention relates to a tensioning device and a control method of a fully-mechanized mining face scraper conveyor and a transfer machine required for explosion protection, in particular to an automatic tensioning device and a control method of a fully-mechanized mining face. Background technique [0002] At present, the scraper conveyor and transfer machine in the fully mechanized mining face of the coal mine transport the produced minerals upwards to the ground storage. In terms of its system composition, it generally consists of a head frame, a tail frame, a scraper conveyor chain and other components. As time goes by, the distance between the nose frame and the tail frame will change, which will easily cause mechanical failure, reduce the service life of chains, sprockets, gear sleeves, scrapers and other components, and affect the whole machine At the same time, it will also lead to a series of very serious safety accidents, which will affect th...
