Abstract

A belt breakage hydraulic protection apparatus for a belt conveyor comprises multiple belt breakage hydraulic protection apparatuses equipped on the belt conveyor, corresponding multiple sensors, a control system composed of a terminal programmable controller and multiple sub-station PLC programmable controllers via advanced communication modules, and multiple hydraulic pump stations, wherein the electric control system can acquire and judge the belt breakage signals in time and send out instructions without resulting in mistaken braking actions, the actuating mechanism of the belt breakage hydraulic protection apparatus employs the oil pumps of hydraulic pump stations and multiple airbag type accumulators to transport high pressure oil to a pull-push oil cylinder, a rotary cylinder and a lifting cylinder, the cylinders drive a top-rising beam below the upper belt to rotate and an up-pressing beam above the upper belt to move up and down to press the broken upper belt; the lifting cylinder lift a lifting beam to move up and down to press the broken lower belt. The top-rising, up-pressing beam and lifting beam have a case type structure, and friction plates are disposed between the beams and the belt contact surface to get big brake force and obvious brake effect, so that the conveyor will not generate loading stop phenomenon and abrade the belt.

Description

technical field

[0001] The invention relates to the technical field of a belt conveyor, in particular to hydraulic protection equipment for belt breakage of a belt conveyor with a large inclination angle. Background technique

[0002] At present, most of the belt conveyors are not equipped with a broken belt arresting protection device. Usually, the belt is checked manually. Due to the harsh operating environment of the mine, maintenance is very inconvenient. The conveying distance of the belt conveyor is long, especially when conveying at a large inclination angle. Once the belt is suddenly broken during the conveying process, if the belt cannot be braked in the shortest time to force the belt to stop sliding, its destructive power is unprecedented and will damage the equipment. And serious personal injury, the loss is huge.

[0003] With the rapid development of the national economy, safe production and civilized production have been paid more a...
