Belt conveyor protection device for coal mine

Abstract

The invention belongs to the technical field of conveyor protection devices and particularly relates to a belt conveyor protection device for a coal mine. The belt conveyor protection device for the coal mine comprises a core mine intrinsic safety type programmable logic controller and a signal detection unit connected with the programmable logic controller. The signal detection unit comprises sensors and amplified phones. The sensors comprise the coal piling sensor, the mine smoke sensor, the speed detection sensor, the mine temperature sensor, the mine belt deviation sensor and the mine intrinsic safety type longitudinal tear sensor. The amplified phones comprise the mine intrinsic safety type sudden stop amplified phone, the mine intrinsic safety type pull rope sudden stop amplified phone A and the mine intrinsic safety type pull rope sudden stop amplified phone B. The belt conveyor protection device for the coal mine has the advantages that programming can be conducted on site, the number of input / output points can be increased, work is reliable, operation is convenient, expansion is flexible, the design is flexible, protective functions are complete, display information is abundant, and control interlocking and protection functions of related devices can be achieved reliably and conveniently.

Description

Technical field [0001] The invention belongs to the technical field of conveyor protection devices, and specifically relates to a belt conveyor protection device for coal mines. Background technique [0002] The working environment of belt conveyors used in coal mines is harsh, complicated and dangerous. The entire equipment has a huge work flow line. When a fault occurs, the maintenance workload is large. The linkage adjustment is time-consuming and labor-intensive. It requires real-time monitoring of the status of the entire equipment's many operating parts. Respond to potential failure factors in a timely manner, so that the various components of the equipment can operate normally. This requires dedicated connection with a large number of temperature, smoke, deviation sensors, solenoid valves, vacuum switches and other protection devices for live action equipment Real-time detection and protection are carried out to ensure the normal operation of the equipment. Each sensor mon...

Problems solved by technology

[0002] The working environment of belt conveyors used in coal mines is harsh, complicated and dangerous. The entire equipment has a huge working assembly line, and the maintenance workload is large when a fault occurs. The linkage adjustment is time-consuming and labor-intensive. It is necessary to monitor the status of many operating parts of the entire equipment in real time. Respond to potential failure factors in a timely manner so that the various components of the equipment can operate normally and coordinately. For this, special connections are required to protect devices with a large number of sensors for temperature, smoke, and deviation, solenoid valves, and vacuum switches. Real-time detection and protection are carried out to ensure the normal operation of the equipment. Each sensor monitors the various components of the conveyor in time. When a fault occurs, the sensor will send the detected signal to the host of the protection device. Corresponding to the alarm, generally the existing belt conveyor protection devices for coal mines have a single detection and control method, the overall fixation of the device has no expandable flexibility, the interlocking functionality is not strong, and the operation is inconvenient, which has certain limitations in use
