Problems solved by technology

[0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a coal mine conveyor belt protection device, which is used to solve the secondary damage of the conveyor belt caused by the braking moment of the existing conveyor belt protection device; At the moment of braking, the material on the conveyor belt slides down due to inertia and blocks the roadway; the hydraulic system occupies too much space, the oil circuit is complicated, the leakage of hydraulic oil is large, and the frequent start and stop of the hydraulic pump leads to a short service life of the equipment and increases Possibility of fire caused by frequent start and stop of the hydraulic pump unit; and the technical problem that the braking time of multiple conveyor belt protection devices is not uniform

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] The coal mine conveyor belt protection device of the present invention is mainly used for coal mine conveyor belt protection. The coal mine conveyor belt protection device monitors the running state of the conveyor belt in real time through the encoder 4 or the coal blocking detection device 5 and transmits the monitoring signal to the electric control device for monitoring. After analyzing and judging, an instruction is sent to the hydraulic system 2, and the hydraulic system 2 controls the hydraulic cylinder 210 through the hydraulic pipeline to realize the action of the arresting device 1.

[0033] as attached figure 1 As shown, it includes a capture device 1, a hydraulic system 2, an electrical control device 3, an encoder 4, a coal blocking detection device 5, and a travel switch 6. Send to the electrical control equipment 3, the electrical control equipment...

Abstract

The invention discloses a coal conveyor belt protection device and a working method of the coal conveyor belt protection device. The coal conveyor belt protection device is mainly used for protecting a coal conveyor belt. The coal conveyor belt protection device is characterized in that through an encoder or a coal blocking detection device, the running state of the conveyor belt is monitored in real time and a monitoring signal is transmitted to an electric control device for analysis and judgment; and then a command sent to a hydraulic system, and the hydraulic system controls a hydraulic cylinder to achieve the action of a capturing device. The coal conveyor belt protection device and the working method mainly solve the problems that the leakage of a reversing valve of a hydraulic system of an existing conveyor belt protection device is too large, frequent-start of a hydraulic pump is caused, the energy consumption is large, the system life of the system is short, a motor is burn out easily, and an coal mine accident is caused; secondary damage to the conveyor belt is generated easily at the capturing moment, and materials slide down and block a roadway due to inertia; and an oil way is complex, and the size of a valve block is large.

Description

technical field [0001] The invention relates to a protective device for a coal mine conveyor belt, which belongs to a conveyor belt protective device leading the way in coal mine belt conveyor technology. Background technique [0002] Because of its strong transportation capacity, long transportation distance and low energy consumption, the belt conveyor has become the main underground transportation equipment. With the increase of usage, the impact of the broken belt accident of the large-scale transportation belt conveyor with a large inclination angle on mine production safety will become more and more serious. It is becoming more and more prominent that once the transport plane breaks, the economic loss and social impact will be huge. The conveyor belt and materials after the broken belt accelerates down under the action of gravity, destroying idlers, racks and cables and electrical equipment in the roadway along the way, and even injuring underground workers. Conveyor ...
