AI Technical Summary

Technical Problem

The existing belt conveyor has different tension under no-load and heavy-load conditions, which causes the weight of the belt pulley to swing from side to side, resulting in belt misalignment and slippage. Moreover, the existing misalignment adjustment device is not effective.

Method used

The belt conveyor uses a belt conveyor with a waist wheel weight trolley, including a moving trolley mechanism and a fixed guide rail frame. The tension is adjusted by changing the height of the waist wheel weight, and the movement of the guide wheel is restricted by the rectangular moving trolley body and the channel steel structure guide rail frame to ensure constant tension.

Benefits of technology

It achieves constant tension under both no-load and full-load conditions, avoiding accidents such as belt breakage, slippage, and scratches, and improving equipment operation stability and transportation efficiency.

Abstract

This utility model relates to a belt conveyor's waist wheel weight trolley, including a downward conveyor belt, two fixed pulleys, a redirecting roller, a waist wheel weight, and a steel structure fixed frame. Its key feature is that it further includes a moving trolley mechanism and a fixed guide rail frame. The moving trolley mechanism includes a guide wheel frame and moving guide wheels. The guide wheel frame is a rectangular moving trolley body composed of a transverse frame and a longitudinal frame perpendicularly connected to the transverse frame. An upper fixed frame and a lower fixed frame are fixed parallel to each other within the rectangular moving trolley body. Moving guide wheels are located at the four corners of the longitudinal frame. The fixed guide rail frame is a channel steel structure fixed guide rail frame. The two flanges of the channel steel structure fixed guide rail frame are correspondingly fastened to the outer sides of the moving guide wheels fixed to the rectangular moving trolley body, forming a guide rail frame, allowing the moving guide wheels to roll in contact with the guide wheel frame. Its advantages are: effectively reducing belt damage caused by belt misalignment and increasing the utilization rate of the conveyor belt.
