Description
Technical Field
The invention belongs to the technical field of cleaning conveyer belts of belt conveyors, and particularly relates to an intelligent belt cleaning device with a plurality of sensors integrated for mines.
Background
The belt conveyor is the main equipment of coal mine transportation, for example main transportation system, tunnel excavation and coal preparation factory etc. because its laying distance is long, and operating time is of a specified duration, and the transportation volume is big, and a part of coal of transportation often can glue on the conveyer belt working face, causes the conveyer belt off tracking, increases the running resistance of conveyer belt, accelerates the wearing and tearing of conveyer belt, therefore needs to clean the conveyer belt surface when belt conveyor is worked. Usually the belt sweeper is mostly arranged at the belt head. Because of the limitation of the head space of the belt conveyor and the function of the traditional cleaner, materials are adhered to the belt, and the cleaning effect is not ideal. In the operation process of the belt conveyor, the dust pollution of the whole belt conveyor gallery is serious due to belt jumping in the return section, and the safety production and the personnel health are influenced; meanwhile, the dust concentration between the driving room and the tensioning room is easily increased when coal is carried on the working surface and the non-working surface of the belt, when the water quantity of the coal is large, coal accumulation at the tensioning roller is easily caused, the cleaning difficulty is large, and the belt deviation and even belt tearing phenomena are easily caused when the carrying quantity is too large, so that great potential safety hazards exist.
The pretightning force form of sweeper that uses on the existing market is mostly gravity type and spring, and its volume of gravity type is great, and the spring is along with the wearing and tearing of scraper blade, and the pretightning force can reduce gradually, otherwise cleans the effect variation. Due to the fact that installation space is limited in the underground face of the mine, and due to the fact that the sweeper is different in installation position, the tensioning force spring is difficult to adjust, labor intensity of workers is increased, and safety is reduced. In chinese patent publication No. CN103787054A, a hydraulic constant-torque heavy-section sweeper for a belt conveyor is proposed, specifically, a sweeping block assembly is connected with a rotating mechanism, the rotating mechanism is connected with a piston rod of a hydraulic cylinder through a connecting rod, and a piston cavity of the hydraulic cylinder is connected with an energy accumulator through a rubber tube for compensating the pressure of the piston cavity. In the invention, the hydraulic cylinder is connected with the energy accumulator through the rubber tube to form a hydraulic system, and actually, an oil-gas spring is formed. The hydro-pneumatic spring has a nonlinear displacement force relationship, and the output force characteristic changes along with the movement of the oil cylinder, the change of the gas state in the energy accumulator, the change of the environmental temperature and the like, so that the constant pressing force of the cleaning block and the adhesive tape cannot be ensured. In chinese patent publication No. CN106144505BA, a sweeper with an automatic pre-tightening force compensation function is proposed, which is implemented by adding a set of hydraulic system and electrical system, and this way can achieve the constant pre-tightening force of the sweeper, only can achieve the automatic compensation function, and cannot identify materials on the belt.
