An intelligent coal mine support

Abstract

The invention relates to an intelligent coal mine support, comprising a supporting plate, the supporting plate is hingedly installed with a connecting plate, the connecting plate is connected with a cover beam, the cover beam is hingedly installed with a top beam, and the supporting plate is hingedly installed There is a No. 1 hydraulic cylinder connected to the top beam. The top beam is connected with a supporting device to prevent the top beam from overloading and rotating. The top beam is also equipped with a reinforcement device to increase the bearing capacity of the top beam. The No. 1 hydraulic cylinder, Both the support device and the reinforcement device are connected to a controller. The invention supports the top beam through the cooperation of the non-return rod and the ratchet to prevent the top beam from turning over and causing underground landslides, endangering the safety of workers; the invention enhances the jacking force of the No. 2 hydraulic cylinder through the cooperation of the reinforcing rod and the U-shaped plate, preventing The damage to the No. 2 hydraulic cylinder causes the top beam to turn over and cause landslides; the invention drives the chain wheel to rotate and quickly releases the swing rod through the chain, and at the same time, the No. 3 hydraulic cylinder drives the support rod to support the top beam to prevent the top beam from being overloaded and collapsed, buying time for workers to escape.

Description

technical field [0001] The invention relates to the technical field of coal mine equipment, in particular to an intelligent coal mine support. Background technique [0002] With the vigorous development of the mining industry, the demand for coal mine supports has been greatly increased. The mining conditions under the mine are harsh and the environment is complex. Large-scale automated supports have become the mainstream instead of artificial wooden supports. The existing coal mine supports have single functions and cannot provide alarms when overloaded. As a result, small area landslides occur underground, endangering the safety of workers. At the same time, the concentration of dust and gas in the underground air has always been one of the important factors that endanger underground safety. The different gas concentrations in various mines cannot be fully detected and timely diluted on site to eliminate the danger. Therefore A kind of intelligent coal mine support is need...

At the same time, the concentration of dust and gas in the underground air has always been one of the important factors that endanger underground safety. The different gas concentrations in various mines cannot be fully detected and timely diluted on site to eliminate the danger. Therefore A kind of intelligent coal mine support is needed to solve the above problems
