Belt cleaning device for belt conveyor of normal concrete pouring tunnel lining trolley

Abstract

A belt cleaning device for a belt conveyor of a normal concrete pouring tunnel lining trolley comprises a belt tensioning mechanism, a cleaning mechanism and a water tank which are mounted on a rack. The cleaning mechanism is arranged in the water tank, and the belt tensioning mechanism is matched with the cleaning mechanism to enable a belt to enter the cleaning mechanism in the water tank. The belt tensioning mechanism comprises a manual adjusting wheel, a screw rod and a tensioning wheel. The manual adjusting wheel is connected with the tensioning wheel through a lead screw, and the lead screw is in circumferential limiting connection with the rack. The manual adjusting wheel is in up-down limiting connection with the rack, and the manual adjusting wheel is in screw fit with the lead screw at the same time. The lead screw can drive the tensioning wheel to move up and down in the water tank by driving the adjusting wheel. The tensioning wheel abuts against the non-material-conveying face of the belt. The cleaning mechanism comprises a plurality of cleaning wheels which are mounted on the two sides of the tensioning wheel respectively. Brush hair is arranged on the cleaning wheels, and the tensioning wheel enables the material conveying face of the belt to always abut against the brush hair on the two cleaning wheels. The belt cleaning device for the belt conveyor of the normal concrete pouring tunnel lining trolley has the advantages that the conveying belt can be better protected, and the fault rate of the belt conveyor is lowered.

Description

technical field [0001] The invention relates to a matching device of heavy machinery, in particular to a belt cleaning device for a belt conveyor of a trolley lining trolley for normal concrete pouring. Background technique [0002] The normal concrete pouring tunnel lining trolley is a heavy machinery mainly used in water conservancy and hydropower construction. The concrete lining trolley is a special equipment that must be used in the secondary lining during the tunnel construction process, and is used for the concrete lining construction of the inner wall of the tunnel. Concrete lining trolley is an indispensable machine for secondary lining during tunnel construction. There is a trolley for normal concrete pouring tunnel lining [0003] An important part is the concrete conveyor, which usually sends the mixed concrete to the pouring cavity built by the formwork through the belt. The inventor of this patent application found that the belt conveyors of the pouri...

AI Technical Summary

Problems solved by technology

The inventor of this patent application found that the belt conveyors of the pouring distribution system of the normal concrete pouring tunnel lining trolley currently used at the construction site do not have the function of automatically cleaning the belt

The belt conveyor often drags the concrete after feeding, and the concrete has a certain viscosity and is easy to solidify. Once the concrete is attached to the belt and is not cleaned in time, it will be difficult to clean up later, which will cause serious damage to the belt conveyor. Frequent failures of belt conveyors
