Dredging robot for coal conveying system

Abstract

The invention discloses a dredging robot for a coal conveying system, and belongs to the field of coal conveying. The invention provides a coal drop pipe dredging robot which is high in flexibility and good in operation effect. According to the technical scheme, the dredging robot for the coal conveying system comprises a robot body and a tool bit assembly, wherein the robot body is a mechanical arm with at least two shafts; a tool bit assembly is fixed to the tail end of the mechanical arm; the tool bit assembly comprises a telescopic piece and a tool bit; one end of the telescopic piece is connected with the tail end of the mechanical arm; and the tool bit is fixed to the other end of the telescopic piece.

Description

technical field [0001] The invention is a dredging robot for a coal conveying system, which belongs to the field of coal conveying. Background technique [0002] Coal-fired thermal power plants need to quantitatively transport pulverized coal or coal slime to the boiler for combustion through conveyor belts and coal falling pipes. [0003] When coal slime is used as fuel, the moisture in the coal slime accounts for 16% of the total mass. Therefore, in the coal transportation system, the coal outlet of the coal transportation trestle will often be blocked, and in severe cases, the coal slime will overflow. Greatly affect production safety and efficiency. [0004] In addition, the coal drop pipe is a square structure, and the internal angle is 90 degrees dead angle, which is easy to form adhesion and block coal at the dead angle position; some coal drop pipes are installed with three-way baffles, and the three-way baffles are easy to Deformation or limited position is not i...

Problems solved by technology

Therefore, in the coal transportation system, the coal outlet of the coal transportation trestle will often be blocked, and in severe cases, the coal slime will overflow. Greatly affect production safety and efficiency

[0004] In addition, the coal drop pipe is a square structure, and the internal angle is 90 degrees dead angle, which is easy to form adhesion and block coal at the dead angle position; some coal drop pipes are installed with three-way baffles, and the three-way baffles are easy to Deformation or limited position is not in place, so that it will form a certain gap and cause coal blocking; and the coal falling pipe will be equipped with its wear-resistant plate when the impact is severe. Under long-term operation, it is easy to make the wear-resistant plate warp, reduce the flow area, and cause the coal falling pipe to be blocked

[0005] At present, the coal blocking phenomenon is prone to occur mainly on the inclined slope facing the belt and the inclined slope of the three-way partition in the coal falling pipe

Among them, the rotary scraper has been installed on the inclined slope facing the belt, and the blockage problem has been basically solved. However, the coal blockage inside the coal drop pipe cannot be solved quickly. Once the above problems occur, it must be shut down for maintenance, which will seriously affect the normal operation of the equipment.
