Intelligent coal mine support

Abstract

The invention relates to an intelligent coal mine support, which comprises a supporting plate, the supporting plate is installed with a connecting plate in a hinging manner, the connecting plate is connected with a shielding beam, the shielding beam is installed with a top beam in the hinging manner, the supporting plate is provided with a No.1 hydraulic cylinder connected with the top beam in thehinging manner, the top beam is connected with a supporting device which prevents the top beam from being overload rotating, a reinforcing device for increasing the bearing capacity of the top beam is also installed on the top beam; and the No.1 hydraulic cylinder, the supporting device and the reinforcing device are connected with a controller. The intelligent coal mine support can support the top beam through the cooperation of a check rod and a ratchet wheel to prevent the underground collapse caused by the overturn of the top beam; the intelligent coal mine support can enhance the jackingforce of a No. 2 hydraulic cylinder through the cooperation of the reinforcing rod and a U-shaped plate to prevent the collapse of the No. 2 hydraulic cylinder caused by the overturn of the top beamduring the supporting process; the intelligent coal mine support can drive a chain wheel to rotate to release a pendulum rod quickly through a chain, and meanwhile a No. 3 hydraulic cylinder drives asupport rod to support the top beam to prevent the overload collapse of the top beam so as to gain 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...

[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 needed to solve the above problems
