Broken chain monitoring and protecting system for scraper conveyor

Abstract

A broken chain monitoring and protecting system for a scraper conveyor comprises a machine head infrared sensor, a machine tail infrared sensor, a motor, a current transformer, a magnetic starter, an electric parameter collection module, a machine head controller, a machine tail data transmission module, a monitoring host, a horizontal chain ring, a vertical chain ring, a support, an air chamber, air holes, a base, an anti-explosion infrared sensor, a sealing cover, glass, an air channel sealing sleeve, an air inflow nozzle, an air way, a starting button and a shutdown button. The magnetic starter is connected to the motor through the current transformer. The current transformer is also connected to the electric parameter collection module. The electric parameter collection module is connected to the machine head controller. The starting button and the shutdown button are connected to the machine head controller. The base is arranged at one end of the anti-explosion infrared sensor. A protective sleeve is arranged on the outer wall of the anti-explosion infrared sensor. The air chamber is connected to the other end of the anti-explosion infrared sensor through the glass. The sealing cover is arranged on the side wall of the air chamber. The broken chain monitoring and protecting system is simple in overall structure, good in stability and high in reliability.

Description

technical field [0001] The invention relates to a monitoring and protection system for a scraper conveyor, in particular to a chain-breaking monitoring and protection system for a scraper conveyor. Background technique [0002] The scraper conveyor is mainly used in other places such as mining face or trough. It has the advantages of low body, small space occupation, horizontal and vertical bending, and high structural strength. Due to its special structure and good adaptability to harsh working environments, the scraper conveyor is currently the only coal transportation equipment in coal mining face in my country. The scraper chain is the traction component of the scraper conveyor. During the working process, due to the continuous action of dynamic and static loads, the scraper chain will gradually deform, and the distance between the chain links will continue to increase. After a period of use, the chain will relax, such as Failure to adjust in time may easily lead to cha...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art, change the defect that the current scraper conveyor does not have a chain protection device, solve the current situation that the scraper conveyor often has broken chains during operation, and provide a scraper conveyor The machine broken chain monitoring and protection system, without making large-scale changes to the structure and operation mode of the existing scraper conveyor, through the installation of special sensors to monitor the operating current of the driving motor of the scraper conveyor and the temperature of the traction chain of the scraper conveyor, The monitoring of the temperature rise rate can grasp the force of the traction chain and the load capacity of the traction chain in real time during the operation of the scraper conveyor. When the traction force is too large or the chain load capacity drops to the critical point of load, the scraper conveyor is controlled to stop and Send an alarm to notify inspection and maintenance, so as to avoid the occurrence of broken chain faults
