Deviation rectifying device of gravity tensioning mechanism and machining method of deviation rectifying device

Abstract

The gravity tensioning mechanism deviation rectifying device comprises a gravity tensioning roller, locking assemblies are arranged on the two sides of the gravity tensioning roller, sliding assemblies are arranged at the upper ends and the lower ends of the locking assemblies, and sliding rails are slidably connected to the sides, away from the gravity tensioning roller, of the two locking assemblies through the sliding assemblies; the locking assembly comprises a vertical locking rod installed on one side of the gravity tensioning roller through a fixing shaft and fixing bases installed on the surfaces of the upper end and the lower end of the vertical locking rod, and adjusting mechanisms are installed on shells of the fixing bases. The sliding assembly comprises a fixing block installed in the fixing base, a pulley base installed on the surface of the side, away from the fixing base, of the fixing block, and a horizontal wheel rotationally connected with the pulley base through a rotating shaft. The gravity tensioning roller deviation rectifying device can perform deviation rectifying work on the gravity tensioning roller, has the protection effects of preventing a gravity tensioning mechanism from falling off a track, preventing a belt from being abraded and the like, reduces impact on coal conveying equipment due to the fact that the gravity tensioning mechanism is separated from the track and the like, and improves use efficiency.

Description

technical field [0001] The invention mainly relates to the technical field of conveyor belts, in particular to a gravity tensioning mechanism correction device and a processing method thereof. Background technique [0002] During the operation of the conveyor belt in thermal power plants, coal mines and other conveying industries, the gravity tensioning mechanism at the tail of the conveyor belt is under uneven force, which causes the gravity tensioning mechanism and the track to shift, causing the gravity tensioning mechanism to fall off the track and the conveyor belt to deviate and wear the belt , coal and other accidents. [0003] Due to various reasons, such as the gravity tensioning mechanism is affected by equipment aging factors, maintenance process factors, human factors, environmental factors, technical level and management level, etc., there are still unsatisfactory places, especially as the generator set load operation hours increase. Constantly increasing, the ...

Problems solved by technology

[0002] During the operation of conveyor belts in thermal power plants, coal mines and other conveying industries, the gravity tensioning mechanism at the tail of the conveyor belt is under uneven force, resulting in displacement between the gravity tensioning mechanism and the track, causing the gravity tensioning mechanism to fall off the track and the conveyor belt to deviate and wear the belt , coal spilling and other accidents

[0003] Due to various reasons, such as the gravity tensioning mechanism is affected by equipment aging factors, maintenance process factors, human factors, environmental factors, technical level and management level, etc., there are still unsatisfactory places, especially with the increase in the operating hours of the generator set load. Increasingly, the gravity tensioning mechanism of the coal handling system of the thermal power plant falls off the road, which causes equipment outage events to occur frequently

[0004] In order to prevent the gravity tensioning mechanism from falling off the track, it can only be manually adjusted every time. Usually, a hand chain hoist is used to force the deviation. In this way, the driving roller and the driven roller do not have an appropriate amount of loose edge tension, which will easily cause the conveyor belt to slip; There are safety hazards such as lack of compensation length, which will affect the reliable operation of equipment. Technical research will be carried out for the above-mentioned phenomena such as the gravity tensioning mechanism of the coal conveying system of thermal power plants, so as to improve the effect of equipment management
