A protective control device for a conveyor in a coal mine

Abstract

The invention discloses a protection and control device for a conveyor used in coal mines, which comprises two sets of upper support frames and two sets of lower support frames. A first support mounting plate is fixedly connected between the two sets of upper support frames. The first support The lower end of the installation plate is provided with a first cleaning module, and a second cleaning module is arranged between the two sets of upper support frames on one side of the first support installation plate, and is located between the two sets of upper support frames below the second cleaning module. A third cleaning module is also provided. In the protection and control device for a conveyor used in coal mines according to the present invention, the first cleaning module is used in conjunction with the first scraper plate and the second scraper plate to scrape off the large coal slag in two times, which can effectively clean and avoid If the conveyor belt is damaged, the cleaning slats on the second cleaning module can go deep into the concave part of the conveyor belt for cleaning, and the third cleaning module can be used in conjunction with the water spray module to scrub the surface of the conveyor belt, making the cleaning more clean and convenient use.

Description

technical field [0001] The invention relates to the technical field of coal mine conveyors, in particular to a protection and control device for coal mine conveyors. Background technique [0002] In coal mines, belt conveyors are used in coal mines to transport the raw coal mined from the coal mining face to the elevator and then use the elevator to lift the raw coal to the ground. Large, high efficiency, easy automation and other advantages, it has become the main transportation equipment of China's coal mine underground raw coal transportation system. Many coal mines are developing in the direction of "coal transportation belt". This development trend has been recognized by the world. During the process of transporting coal, faults such as running deviation, slipping, broken belt, and longitudinal tearing of the belt conveyor often occur. The above-mentioned faults of the belt conveyor used in coal mines will not only affect the raw coal transportation and coal mining oper...

[0002] In coal mines, belt conveyors are used in coal mines to transport the raw coal mined from the coal mining face to the elevator and then use the elevator to lift the raw coal to the ground. Large, high efficiency, easy automation and other advantages, it has become the main transportation equipment of China's coal mine underground raw coal transportation system. Many coal mines are developing in the direction of "coal transportation belt". This development trend has been recognized by the world. During the process of transporting coal, faults such as running deviation, slipping, broken belt, and longitudinal tearing of the belt conveyor often occur. The above-mentioned faults of the belt conveyor used in coal mines will not only affect the raw coal transportation and coal mining operations in the coal mine, and sometimes cause Causing major safety accidents, timely discovering and preventing the above-mentioned failures of belt conveyors used in coal mines during work is an extremely important task in underground coal mining operations in coal mines. Most of the failures of the conveyor belt are caused by damage to the conveyor belt. The damage is due to the fact that the conveyor belt has not been cleaned for a long time, so that the conveyor belt is stained with a lot of coal slag, which increases the load of the conveyor belt. Therefore, it is necessary to regularly clean the conveyor belt and protect the coal mine conveyor. Therefore, a coal mine conveyor protection is required. control device;

[0003] Most of the existing protection and control devices for coal mine conveyors use a cleaning mechanism to clean the cinders adhering to the surface of the conveyor belt. Due to the long-term use of the conveyor belt, large and small depressions will appear on the surface of the conveyor belt, but the scraper set on the cleaning mechanism It is impossible to clean the sunken parts, which is prone to incomplete cleaning, and the cleaning effect is not ideal, which brings inconvenience to the actual use. Therefore, we propose a protective control device for coal mine conveyors
