Adjustable forklift door frame

Abstract

The invention discloses an adjustable forklift door frame. The door frame comprises a motor tank, a gear box and a movable ring, wherein threads meshed with a threaded outer rod is formed in the outersurface of a threaded inner rod; a through hole runs through the threaded outer rod; the other end of the threaded inner rod is connected with a baffle; the other side of the baffle is connected withan outer door frame; the surface of a movable rod is sleeved with the movable ring; the gear box is fixedly arranged on the surface of the upper end of an L-shaped rack; two supporting rods are respectively arranged on bottom bulge of the gear box; bearings are embedded on the surfaces of the supporting rods; and forks are arranged on left and right sides of the threaded rods, and spacing blocksare arranged at left and right ends of the threaded rods. Compared with a conventional fork which requires manual movement to change width, the fork has the advantages that mechanical transmission ismore convenient, and the work intensity of labors is reduced; a slide block is additionally arranged at the bottom of the fork and can move on a slide groove to achieve a certain spacing effect, so that the phenomenon that the fork cannot be moved can be prevented; and the movable ring is designed to detach the gear box.

Description

technical field [0001] The invention relates to the technical field of forklift accessories, in particular to an adjustable forklift mast. Background technique [0002] Forklift is an industrial handling vehicle, which refers to various wheeled handling vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. The International Organization for Standardization is called an industrial vehicle. It is often used for the transportation of large objects in storage. It is usually driven by a fuel engine or a battery. It is composed of frame, fork frame, fork, sprocket, chain, lifting cylinder and tilting cylinder. [0003] And now there are many forklift masts on the market, but the forks of most forklift masts are moved manually to realize the change of width, which not only makes the work efficiency low, but also makes the labor intensity of the staff Multiplied, and once the forklift mast is installed, it is generally difficult to dis...

Problems solved by technology

[0003] And now there are many forklift masts on the market, but the forks of most forklift masts are moved manually to realize the change of width, which not only makes the work efficiency low, but also makes the labor intensity of the staff Multiplied, and once the forklift mast is installed, it is generally difficult to disassemble, making maintenance even more inconvenient
