Ninth belt protecting device of heavy belt conveyer

Abstract

A ninth belt protecting device of a heavy belt conveyer comprises a tail drum and a belt as well as a primary sweeper, a secondary sweeper, an angle iron and a pull wire emergency stop switch. The primary sweeper is fixed, and abuts on the belt, and the secondary sweeper is fixed with one end of a rotating shaft type; the other end of the secondary sweeper is provided with the pull wire emergencystop switch in a binding manner, and arranged on the angle iron with 20 cm stroke; and a gap of 2-5 cm is provided between the secondary sweeper and the belt. The invention aims to provide the ninth belt protecting device of the heavy belt conveyer, with the advantages of reliable emergency stop protection action, easy maintenance, quick and reliable interception, simple design, easy machining andquick installation.

Description

technical field [0001] The invention relates to a ninth belt protection device for a powerful belt conveyor. Background technique [0002] Mine hoisting transport tear belt accident is one of the most harmful accidents. Once the tape is torn due to human error, untimely discovery or damage to the tape, in addition to causing coal sprinkling and deviation, it will also cause a broken tape and lead to personal accidents in severe cases. Therefore, the anti-tear belt protection is one of the essential safety facilities in lifting transportation. [0003] The protection installed on the belt conveyor of the main transportation system includes: coal pile protection, speed protection, deviation protection, tear protection, smoke monitoring, temperature protection and automatic sprinkler device, emergency stop and lock protection along the line, and tension drop protection. 8 types of belt protection, but these 8 types of belt protection still cannot guarantee the normal operatio...

[0003] The protection installed on the belt conveyor of the main transportation system includes: coal pile protection, speed protection, deviation protection, tear protection, smoke monitoring, temperature protection and automatic sprinkler device, emergency stop and lock protection along the line, and tension drop protection. 8 types of belt protection, but these 8 types of belt protection still cannot guarantee the normal operation of the conveyor, because the tear protection only protects when the belt is torn, and cannot prevent it. Pandao Coal Industry in 2015 There were two belt tearing accidents because the tail of the conveyor entered gangue. Although the cleaner was installed at the tail of the machine, sometimes the gangue would pass over the cleaner and enter the tail drum. Because the gangue in our mine is high in hardness, the wire rope belt would be torn cracked or broken, resulting in belt tearing accidents
