Carrier roller replacing vehicle under working state of belt conveyor

Abstract

The invention relates to a carrier roller replacing trolley under the working state of a belt conveyor. The carrier roller replacing vehicle comprises a chassis, a turntable, a supporting seat, guide columns, supporting arms, a manipulator, a standby carrier roller rotating disc and a standby carrier roller. The chassis comprises an operation table, a crawler walking device, a hydraulic system and the like. The supporting seat bears all replacement mechanisms. Each supporting arm comprises a carrier roller support, a carrier roller, a supporting sliding rail, a hydraulic motor and the like. The manipulator comprises a hydraulic cylinder, a clamping device, a hydraulic motor and the like. The standby carrier roller rotating disc comprises a rotating disc, a rotating disc support, a servo motor and the like. When the carrier roller replacing vehicle runs to the damaged carrier roller, the supporting arms extend into the two sides of the damaged carrier roller and support a conveying belt after rotating so that the damaged carrier roller can be separated from the conveying belt, and the manipulator extends into the damaged carrier roller to clamp out the damaged carrier roller, convey the damaged carrier roller to the standby carrier roller rotating disc, take down the standby carrier roller and return to the damaged position for replacement. According to the carrier roller replacing vehicle under the working state of the belt conveyor, the damaged carrier roller can be replaced in the working state of the belt conveyor, and energy losses caused by starting and stopping of a large conveyor are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of replacing idler rollers of conveyors, in particular to an idler roller replacement vehicle in the working state of a belt conveyor. Background technique [0002] Belt conveyor is an important material transmission equipment in fully mechanized mining equipment. The belt conveyor used in coal mine has the characteristics of large transportation volume, complex working environment, strong carrying capacity and long transportation distance. The idler roller is an important part of the belt conveyor, which can support the conveyor belt and the material. The number of long-distance conveyor idler rollers is huge, and the inset resistance between the conveyor belt and the idler and the wear resistance between the conveyor belt and the material will cause transportation resistance. , when the idler roller is damaged, it will further increase the conveying resistance of the conveyor, resulting in serious wear of ...

The idler roller is an important part of the belt conveyor, which can support the conveyor belt and the material. The number of long-distance conveyor idler rollers is huge, and the inset resistance between the conveyor belt and the idler and the wear resistance between the conveyor belt and the material will cause transportation resistance. , when the idler roller is damaged, it will further increase the conveying resistance of the conveyor, resulting in serious wear of the conveyor belt and seriously affecting the transmission efficiency of the conveyor. At this time, it is necessary to replace the damaged idler roller. However, the shutdown of the long-distance conveyor requires the shutdown of the entire fully mechanized mining system, resulting in huge economic and work efficiency losses.
