Sectional steel flat support device Rotary arm drive chain tensioner

Abstract

The invention discloses a rotating arm transmission chain tensioning device for a profile steel flat supporting device. The rotating arm transmission chain tensioning device for the profile steel flat supporting device comprises a tensioning wheel, a tensioning wheel fixing shaft and an adjusting rod. The rotating arm transmission chain tensioning device for the profile steel flat supporting device is characterized in that one end of the tensioning wheel fixing shaft extends out of one separating plate and is screwed with a lock nut through threads, strip holes allowing the tensioning wheel fixing shaft to be moved and adjusted up and down are correspondingly formed in the two separating plates where the tensioning wheel fixing shaft is located, a vertically arranged threaded through hole is formed in the middle of the tensioning wheel fixing shaft, the adjusting rod is vertically arranged between the two separating plates, external threads are arranged in the middle of the adjusting rod, the adjusting rod is screwed and matched in the threaded through hole in the middle of the tensioning wheel fixing shaft, the upper end and the lower end of the adjusting rod extend out of the upper side face position and the lower side position of the two corresponding separating plates respectively, and the upper end and the lower end of the adjusting rod are fixed to limiting pieces which butt against and are limited on the upper side face and the lower side face of the two corresponding separating plates respectively. The rotating arm transmission chain tensioning device for the profile steel flat supporting device has the advantages of being simple and compact in structure, fast, convenient and stable in adjusting, long in service life, good in stability and the like.

Description

technical field [0001] The invention relates to a flat support device for a row of profiled steel stands, in particular to a tensioning device for a transmission chain of a rotating arm of the profiled steel flat support device. Background technique [0002] Rows of profiled steel rack flat supporting device, a device used to transfer steel between rows of racks. Existing pinto devices such as figure 1 As shown, it includes a supporting rotary table 1 and a tray 2. A rotating arm is connected between the lower part of the tray 2 and the upper part of the supporting rotating table 1. The rotating arm is composed of two strip-shaped partitions 3 arranged vertically at intervals. A transmission chain 4 is arranged for power transmission between the supporting rotary table and the lower part of the pallet, and a tensioning mechanism for tensioning the transmission chain is also provided on the rotating arm. For the existing tensioning mechanism, see figure 1 and figure 2 , i...

AI Technical Summary

Problems solved by technology

[0003] This existing structure is relatively simple and easy to implement, but because the tensioning wheel is cantilevered on one side of the partition, the compactness and stability are very poor. After the adjustment bolts are tightened, the sprocket will tilt on one side and run for a period of time. Afterwards, it will gradually become loose, and the purpose of locking the chain cannot be achieved.
