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

Abstract

The invention provides an on-site maintenance method for the rubber coating layer of the head drum of a reclaimer, which includes: judging whether the retractable distance of the head drum meets the requirements of segmented rubber coating; pre-adjusting the position of the conveyor belt and the operating space; The belt is slowly pulled out of the idler frame along the vertical direction of the belt conveyor until nearly half of the head drum is exposed; the exposed part of the head drum is subjected to cold vulcanization lagging, and after the completion of static curing; the remaining part of the head drum is cold vulcanized Lagging, handle the joints of the covering layer well, and complete the static curing. The invention is an on-site maintenance method for the rubber covering layer of the head drum of a reclaimer, through the pre-adjustment of the conveyor belt, the segmented rubber coating of the head drum and the seam treatment of the rubber layer, the head drum can be repaired The segmental lagging of the lagging layer has the characteristics of no damage to the conveyor belt, convenient operation and good lagging 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...
