Crane jib special for forklift

Abstract

The invention relates to a crane jib special for a forklift. The crane jib comprises a bracket, a cantilever and a hook, wherein the bracket consists of a base, four struts and a top plate; the base is formed by welding a left frame, a right frame, a front frame and a rear frame; the lower ends of the left front strut and the left rear strut are welded on the left frame of the base; the lower ends of the right front strut and the right rear strut are welded on the right frame of the base; the upper ends of the left front strut, the left rear strut, the right front strut and the right rear strut are converged on the top plate and welded on the bottom surface of the top plate; the cantilever consists of a square steel tube; the rear bottom end of the cantilever is welded with a joint plate; the joint plate is connected with the top plate of the bracket through a bolt fastener; the cantilever is provided with a ring; the hook is connected on the lug of the ring through a pin shaft; the left frame and the right frame of the base are sleeved on the pallet fork of the forklift; and a safety rope is arranged between the rear frame of the base and the erector of the forklift. The crane jib special for the forklift is matched with the forklift, so that the forklift has the function of hoisting goods and the loading and unloading range of the forklift is enlarged; and the crane jib is convenient to use and is safe and reliable.

Description

technical field [0001] The invention belongs to the field of loading and unloading machinery, and relates to forklifts, in particular to a special boom for forklifts. Background technique [0002] Forklift, also known as forklift, is a loading and unloading machine. It consists of a car body, forks, lifting frame, door frame, etc. It is mainly used for loading and unloading of goods, but the forks of forklifts can only lift goods, not hoist goods. For this reason, the notification number is CN201553586, and the Chinese patent titled "A Forklift Auxiliary Boom" discloses a forklift boom structure, including a bracket and a cantilever. The top of the bracket is horizontally provided with a cantilever protruding from the bracket, and the end of the cantilever is welded with a suspension ring. The forklift auxiliary boom with this structure has obvious disadvantages: the detailed analysis is as follows: [0003] First, the bracket is composed of four pillars, the left front an...

AI Technical Summary

Problems solved by technology

[0003] First, the bracket is composed of four pillars, the left front and left rear pillars are arranged in an isosceles trapezoid, and the right front and right rear pillars are also arranged in an isosceles trapezoid. The disadvantage of this arrangement is that the front and rear width of the bracket is too large, and The cantilever is horizontal, and the space under the cantilever is too narrow, which is not conducive to the lifting and loading and unloading of goods

[0004] Second, the left and right front pillars of the bracket are arranged in an isosceles trapezoid, and the left and right rear pillars are also arranged in an isosceles trapezoid. The disadvantage of this arrangement is that the left and right width of the bracket is too large, occupying two There is too much side space. When the fork moves to the left or right, the bracket is easy to touch the people and goods on both sides, which is not safe and hinders the driver's vision.

[0005] Third, the cantilever and the bracket are welded together, which is bulky and heavy, and cannot be quickly disassembled and disassembled, which is not conducive to the conversion function of the forklift, from the function of hoisting goods to the function of lifting goods

[0006] Fourth, the lifting ring is welded to the end of the cantilever, and the lifting ring cannot be adjusted forward and backward along the extension direction of the cantilever, so the center of gravity of the cargo relative to the forklift cannot be changed. Although the forklift is maneuverable and flexible, its front and rear wheelbase is relatively short. For heavy goods, the center of gravity of the goods is very forward, so the forklift is easy to lean forward and lose its balance

[0007] Fifth, the bracket base is sleeved on the fork of the forklift through flat steel pipes. There is no safety device. During the lifting and tilting process of the fork, the bracket base is easy to fall off from the fork of the forklift, which poses a greater safety hazard
