Field maintenance method for coating layer of material taking machine head part roller

Abstract

The invention provides a field maintenance method for a coating layer of a material taking machine head part roller. The field maintenance method comprises the following steps that whether the returndistance of the head part roller meets the requirement for sectional coating or not is judged; the position and the operation space of a conveying belt are pre-adjusted; the conveying belt is slowly pulled out of a carrier roller frame along the vertical direction of the belt conveyor, and the head part roller is exposed to be close to one half of a barrel body; cold vulcanization packaging is carried out on the exposed part of the head part roller, and static curing is carried out after the head part roller is completed; the residual part of the head part roller is subjected to cold vulcanization and coating, the joint of the coated rubber layer is treated, and static curing is completed. The field maintenance method for the coating layer of the material taking machine head part roller, through the pre-adjustment of the conveying belt, the segmented coating of the head part roller and the joint processing of the coating layer, so that the segmented coating of the rubber layer of the head part roller can be realized, and the field maintenance method has the characteristics of no damage to the conveying belt, convenience in operation and good rubber coating effect.

Description

technical field [0001] The invention belongs to the field of port engineering machinery, and in particular relates to an on-site maintenance method for the rubber coating layer of the head drum of a reclaimer. Background technique [0002] In order to reduce the weight of the whole machine, improve safety, and facilitate the adjustment of the tensioning device, the tensioning mechanism of the boom conveyor belt of the reclaimer mostly adopts a hydraulic tensioning device, adjust the position of the head roller to meet the tensioning pressure requirements, and then the screw device Mechanical lockout to prevent insufficient tension due to pressure release in the hydraulic system. In order to avoid collision between the boom head roller and the material pile during the reclaiming operation, the distance between the head roller and the head guide groove should not be too large after the head roller is tensioned in place, which leads to the maintenance and replacement of the hea...

AI Technical Summary

Problems solved by technology

[0004] The difficulty of on-site maintenance of the rubber coating layer of the head drum of the reclaimer also lies in the small tensioning stroke of the boom conveyor belt, and the small maintenance space between the conveyor belt and the drum after the tensioning device is released. Under the existing technical conditions, according to The traditional encapsulation process is very difficult to implement, and there is an urgent need for a new method for on-site encapsulation of the head drum of the reclaimer
