AI Technical Summary

Technical Problem

The outer distance of existing guide wheels is mostly fixed or simply linearly adjusted, which makes the operation cumbersome and the structure unstable. It is easily displaced by impact and cannot ensure that the forklift can move forward or backward stably on the mechanical guide rail.

Method used

A combined structure of a guide wheel bracket, inner adjustment gasket, outer adjustment gasket and connecting bolts is adopted. By adjusting the number of inner and outer adjustment gaskets at the rear end of the guide wheel bracket and the locking bolts of the guide wheel shaft, convenient adjustment of the guide wheel height and outer distance can be achieved. Combined with the design that the central axes of the guide wheel shaft and the bottom wheel shaft do not overlap, precise adjustment of the guide wheel can be achieved.

Benefits of technology

It improves the operational convenience and structural stability of the guide wheels, ensures a high degree of matching between the guide wheels and the mechanical track, and improves the stability and operating efficiency of the forklift in narrow channels.

Abstract

The guide wheel adjusting mechanism suitable for the narrow-channel forklift comprises a guide wheel support, and the guide wheel support is fixedly connected to the bottoms of the two sides of the forklift through an inner adjusting gasket, an outer adjusting gasket and a connecting bolt; a shaft hole is vertically formed in the front end of the guide wheel support, a penetrating notch is formed in the front end of the guide wheel support in the axial direction of the shaft hole, and a threaded hole is formed in the guide wheel support. A guide wheel shaft is in threaded connection with the threaded hole through a locking bolt so as to lock the shaft hole; the bottom end of the guide wheel shaft is fixedly connected with a bottom wheel shaft, the center axis of the guide wheel shaft does not coincide with the center axis of the bottom wheel shaft, and the bottom wheel shaft is rotationally connected with a guide wheel. According to the device, the inner adjusting shim and the outer adjusting shim can be exchanged with each other, coarse adjustment of the outer side distance of the guide wheel is successfully achieved, operation convenience is improved, meanwhile, the central axis of the guide wheel shaft and the central axis of the bottom wheel shaft are not coincident, fine adjustment of the outer side distance of the guide wheel is successfully achieved, and therefore advancing or retreating of a forklift is better facilitated.
