Longitudinal tearing protection device for coal conveying belt

Abstract

The invention discloses a longitudinal tearing protection device for a coal conveying belt. The longitudinal tearing protection device comprises: a coal conveying rack, wherein a first connecting rod is fixedly connected to the upper end of the coal conveying rack, a rolling roller is mounted on the first connecting rod, a coal conveying belt is mounted on the rolling roller, a second connecting rod is arranged on the coal conveying rack in a penetrating manner, an aluminum turning plate is fixedly connected to the outer wall of the second connecting rod, and a fixed bearing abutting against the outer wall of the coal conveying rack is connected to the second connecting rod in a threaded mode; a protection assembly, wherein the protection assembly comprises a proximity switch fixedly connected to the inner wall of the coal conveying rack. The problems that a transmission belt is mostly used for conveying materials and serves as a unique channel for unloading coal entering a factory, operation safety is very important, if the transmission belt is punctured by a sharp object, coal conveying equipment loses preparation, great pressure is brought to coal conveying operation, in case that equipment in each equipment link breaks down, output of a generator set is directly reduced, and even the generator set is forced to stop, so that the safety production is seriously influenced, and heavy economic loss is caused.

Description

technical field [0001] The invention relates to the technical field of transfer vehicles, in particular to a longitudinal tear protection device for a coal conveyor belt. Background technique [0002] The transmission belt is mostly used for material transportation. The total length of the No. 1 belt of the coal handling system of Huaneng Anyuan Power Plant is 640 meters. As the only channel for entering coal and unloading coal, the operation safety is of great importance. The entire belt was cut by the broken dumper unloading hopper activated coal feeder adjustment rod. The repair period was nearly ten days, and the material cost for the belt replacement alone was nearly 500,000 yuan. It also caused a sharp drop in coal inventory and endangered power generation. The operation of the unit is safe. For this reason, we propose a longitudinal tear protection device for the coal conveyor belt. Contents of the invention [0003] The purpose of the present invention is to provi...
