Anti-collision early warning device and method for top beam of hydraulic support and roller of coal mining machine

Abstract

The invention provides an anti-collision early warning device and method for a top beam of a hydraulic support and a roller of a coal mining machine. The early warning device comprises a movable monitoring early warning device and a laser receiving device. The mobile monitoring and early warning device mainly comprises a bearing box, a rotary laser range finder, a reference seat, a first hinge lug plate, a walking supporting plate, a walking wheel, a supporting wheel, a wheel shaft, a data storage module, a calculation module, a control module and an early warning module. The laser receiving device mainly comprises a fixing plate and a laser receiving module; the movable monitoring and early warning device is provided with four walking wheels and four supporting wheels, the movable monitoring and early warning device is placed on the cable trough, when the walking wheels make contact with a side plate of the cable trough, the walking wheels can roll on the side plate of the cable trough to drive the movable monitoring and early warning device to move, and when the cable trough inclines, the walking wheels can roll on the side plate of the cable trough to drive the movable monitoring and early warning device to move. The supporting wheels are in contact with the side plates of the cable trough, so that the mobile monitoring and early warning device can move smoothly. By adopting the anti-collision early warning device and method for the hydraulic support top beam and the coal mining machine roller, interference detection and early warning of the roller and the hydraulic support top beam in the coal cutting process of the coal mining machine can be achieved, and the anti-collision early warning device and method have the advantages of being easy to operate, high in adaptability, high in precision and the like.

Description

technical field [0001] The invention belongs to the field of intelligent mining of coal mining face, and in particular relates to an anti-collision early warning device and anti-collision monitoring which are suitable for the hydraulic support top beam and the shearer drum in the coal mining process of the coal mining face during the coal cutting process Early warning method. Background technique [0002] With the rapid advancement of the fourth industrial revolution, the new generation of information technology such as 5G, big data, and the Internet of Things has been integrated with the mining technology of the working face, which has greatly improved the mining efficiency and safety level of the working face. According to incomplete statistics, by the end of 2020, the number of intelligent mining working faces in my country has reached 494, and the number of coal mining working faces has been reduced, safety increased, and efficiency improved. However, some intelligent mi...
