Staggered automatic deviation-rectifying device for belt conveyor

Abstract

A staggered automatic deviation-rectifying device for a belt conveyor comprises a power portion, execution portions, a bottom frame, staggered carrier rollers, a rotatable bracket, a supporting bottom frame, a connecting rod mechanism bottom frame, a connecting rod mechanism, a load limiting device, a stop roller, rotating shafts and a middle frame longitudinal beam. The power portion comprises the stop roller and the connecting rod mechanism, the stop roller is connected with one end of the connecting rod mechanism through the load limiting device, the other end of the connecting rod mechanism is connected with the rotatable bracket through a hinge joint, the execution portions are arranged on two sides of the rotatable bracket in a staggered manner through four equal-diameter staggered carrier rollers, and the connecting rod mechanism and the rotatable bracket are fixed onto the connecting rod mechanism bottom frame through the rotating shafts. When a conveying belt deviates, thrust of the stop roller is directly converted into deflecting force of the bracket, and the device is sensitive and reliable in action, large in deviation adjusting amplitude, high in deviation-rectifying capacity, simple and reliable in structure, good in rigidity, smooth in operation, low in running noise and applied to the field of bulk materials.

Description

technical field [0001] The invention relates to a staggered automatic deviation correction device for a belt conveyor in the field of bulk material conveying equipment. Background technique [0002] At present, the bulk material belt conveyor is carried by the idler group to support the conveyor belt to carry the material to complete the conveying work. According to different purposes, the idler group can be divided into various forms such as ordinary bearing, transition, buffer, and self-aligning. When the conveyor is running, the deviation of the conveyor belt may be caused by equipment manufacturing errors, installation errors, eccentric material loading, poor tension distribution of the conveyor belt joints, damage to the idlers, deformation of the frame, cross wind, etc. In order to prevent and correct the deviation of the conveyor belt, in addition to adjusting the position of the fixed equipment, it is generally necessary to set up a special self-aligning idler group...

AI Technical Summary

Problems solved by technology

However, the mechanical type has problems such as excessive wear of the conveyor belt, low deviation correction ability, and the hydraulic type has problems such as complex equipment, low life and high cost, and the actual application effect is not ideal.
