Belt breakage catching device of belt type conveyor

Abstract

The invention discloses a belt breakage catching device of a belt type conveyor. The belt breakage catching device comprises a control host, a belt breakage detection device and multiple catching substations. The control host and the catching substations are connected through communication lines. The control host is further connected with the belt breakage detection device. The catching substations are evenly arranged on the belt type conveyor at equal intervals. When a belt breakage accident happens, a sensor detects a belt breakage signal, the control host issues a catching instruction to each catching substation, control units are connected with electromagnetic valves after the catching substations receive the instruction, air enters air cylinders through air inlets, piston rods of the air cylinders stretch out, lower gate segment air cylinder piston rods drive sliding blocks to move forwards along guide rails, guide rods connected to knuckle bearings are pushed, and then the sliding blocks in the perpendicular direction are pushed to move upwards to be in fit with upper gate segments of upper catching mechanisms. According to the belt breakage catching device, a belt breakage catching device of a coal mine belt type conveyor is unreasonable in solved, the structure is simple, testing and overhaul are convenient, and the equipment manufacturing cost is low.

Description

technical field [0001] The invention relates to a broken belt arresting device of a belt conveyor, which belongs to the technical field of conveyor belt protection. It is especially suitable for broken belt protection of inclined belt conveyors used in metallurgical mines, coal mines, port terminals and power plants. Background technique [0002] Belt conveyors are used in many fields. When a broken belt occurs on a belt conveyor, especially an inclined, long-belt, or large-capacity belt conveyor, it will cause long-term production stoppages and huge economic losses, even machine crashes. , the consequences are extremely serious. [0003] At present, there are many kinds of broken belt arresting devices for belt conveyors, but there are still the following problems: when catching the brake belt, some use line contact, the braking force is small, the braking force is concentrated, and it is easy to damage the belt; Contact, the arresting force reaches a large moment, and it...

Problems solved by technology

[0002] Belt conveyors are used in many fields. When a broken belt occurs on a belt conveyor, especially an inclined, long-belt, or large-capacity belt conveyor, it will cause long-term production stoppages and huge economic losses, even machine crashes. , the consequences are extremely serious

[0003] At present, there are many kinds of broken belt arresting devices for belt conveyors, but there are still the following problems: when catching the brake belt, some use line contact, the braking force is small, the braking force is concentrated, and it is easy to damage the belt; Contact, the arresting force reaches a large moment, and it is easy to damage the belt; existing similar products mainly use purely mechanical structures to solve these problems, but due to the harsh working environment of the broken belt catcher, the purely mechanical structure is often stuck due to rust If there is a failure due to mechanical action defects or other reasons, the problem of capture failure is prone to occur in the case of unmanned monitoring, thus affecting the working stability of the broken belt catcher
