Downwards transportation belt machine anti-sliding damping system for coal mine

Abstract

The invention discloses a downwards transportation belt machine anti-sliding damping system for a coal mine, and belongs to sealing-tape machine auxiliary anti-sliding machinery. The system comprises a hydraulic control device, an electric control device and an actuating mechanism, wherein the hydraulic station of the hydraulic control device is connected with a reversible lock through a liquid inlet rubber pipe and a liquid return rubber pipe; the reversible lock is connected with a first compressing oil cylinder and a second compressing oil cylinder through the liquid inlet rubber pipe and the liquid outlet rubber pipe; an electromagnetic valve is connected among the reversible lock, the first compressing oil cylinder and the second compressing oil cylinder in parallel for controlling the opening and closing of an oil line; the oil return opening of the electromagnetic valve is connected with an oil overflow tank; the hydraulic station oil pump switch of the electric control device is positioned at an engine head for controlling the positive and negative rotation of the oil pump; a belt machine starting switch is positioned at the engine head for controlling the belt machine to start and stop; the electromagnetic valve control box is placed close to the actuating mechanism; the damping tile of the actuating mechanism is fixed on a damping tile base; a guiding device is arranged at the bottom of the damping tile base; an elastic brake is hinged to the lower parts of the two ends of the center line of the damping tile base; a fixing support is connected with a belt rack. The system has the advantages that the device is simple in structure, sensitive and swift, large in friction resistance, and reliable and quick in sliding resistance.

Description

technical field [0001] The invention relates to an auxiliary anti-skid machine for a belt conveyor, in particular to an anti-skid damping system for a belt conveyor used in coal mines. Background technique [0002] Under the condition of sudden heavy-load parking or heavy-load open-gate conveyor in coal mine, the belt conveyor is prone to slide due to the load inertia force, causing the belt to slip on the driving roller, even sliding for several meters, causing carbon dioxide If the nose (tail) of the machine is buried, it will slide for dozens of meters, causing carbon to block the roadway. In more serious cases, the belt will slide faster and faster, resulting in "speeding", causing major mechanical or personal accidents. Contents of the invention [0003] The purpose of the present invention is to provide an anti-slip damping system for belt conveyors in coal mines, which can solve the problems of the belt conveyor belt slipping under the action of load inertia force, ...
