Robot for maintaining parallel supporting roller of conveyor

Abstract

The invention provides a robot for maintaining a parallel supporting roller of a conveyor. The robot comprises a machine seat which can move in a conveying direction, a grasping manipulator unit whichis positioned in the centre of the machine seat and liftable opening and closing manipulators which are positioned at the two ends of the machine seat; the grasping manipulator unit is used for grasping a drum of the parallel supporting roller; the two opening and closing manipulators are used for respectively grasping two limiting shaft parts of the same parallel supporting roller; the graspingmanipulator unit comprises a rotary worktable which is positioned in the centre of the machine seat, a lifter which is fixed to the rotary worktable, an overturning device which is positioned on the lifter, and a grasping manipulator which is positioned on the overturning device; each opening and closing manipulator comprises a bottom slideway and two parallel straight arms which can be connectedto the bottom slideway in a sliding manner; and a rotating belt is arranged in each inner cavity of each of the two straight arms. According to the robot for maintaining the parallel supporting rollerof the conveyor, the replacement of the parallel supporting roller of the conveyor can be completed automatically; the maintenance efficiency can be improved; the labour intensity and the operating risk can be reduced; and the robot for maintaining the parallel supporting roller of the conveyor is positioned in the conveyor and does not occupy additional space.

Description

technical field [0001] The invention belongs to the technical field of automatic maintenance tooling, and in particular relates to a robot for maintaining parallel rollers of a conveyor. Background technique [0002] Conveyors are widely used in metallurgy, coal, coal mines, heavy industry and agricultural production. Most conveyors complete material transportation through parallel rollers and belts. They are usually used for long-distance transportation over 500 meters. Their operating conditions determine the overall efficiency of the production line. [0003] The main failure mode of the conveyor mainly occurs on the parallel rollers, mainly including the detachment of the rollers and the wear of the parallel rollers. In addition, during use, sand and dust will enter the bearings of the parallel rollers and the gap between the parallel rollers and the belt, which will accelerate the damage of the bearings and the outer surface of the parallel rollers, making the failure ...

AI Technical Summary

Problems solved by technology

Once the parallel idler fails, the staff need to carry the heavy parallel idler and walk a long distance under harsh conditions such as mountains or underground before arriving at the site for maintenance. The work efficiency is low, the operation risk is high, and the maintenance takes a long time. It will even affect the safe operation of the whole set of equipment
