Pallet fork bracket assembly for engineering machine

Abstract

The invention discloses a pallet fork bracket assembly for an engineering machine. The pallet fork bracket assembly for the engineering machine comprises a bracket, a pallet fork and a bracket base plate welded to the lower portion of the bracket, wherein the upper portion of the bracket and the upper portion of the pallet fork are connected through a first hinge pin, an installation plate is arranged on the lower portion of the pallet fork, the installation plate is located above the bracket base plate, the installation plate and the bracket base plate are connected through a limiting device, and the position of the pallet fork is limited by the limiting device. The pallet fork bracket assembly for the engineering machine is simple in structure and low in cost of maintenance and using, the defects of an existing structure are eliminated from the design, the gap between an existing pallet fork and an existing bracket base plate is removed, shakes are eliminated, the phenomenon that the back side of a pallet fork cracks never happen again, the pallet fork will not rotate around the hinge pin in the working process, and therefore, the working stability and reliability are better, and the efficiency is higher.

Description

technical field [0001] The invention relates to a fork loader, in particular to a fork bracket assembly for engineering machinery. Background technique [0002] During the process of shoveling stones with the forklift, the user often uses the fork to move the stone. When putting down the stone, the user needs to reverse the car and pull the fork out from under the stone. Swing will occur. In the above common working conditions, the fork will rotate around the bracket pin, that is, shaking, and the shaking is accompanied by every working cycle. [0003] The limit structure of the existing pallet fork is as follows: Figure 14 to Figure 16 As shown, an L-shaped hook plate 9 is welded on the back of the pallet fork 2, and the L-shaped hook plate 9 hooks the step welded on the support plate 10 on the bracket to prevent the pallet fork 2 from rotating with the second pin shaft as the axis, that is, Form limit to pallet fork 2. Since the working materials of construction machine...

AI Technical Summary

Problems solved by technology

[0004] 1. There is a gap between the L-shaped hook plate 9 on the back of the fork 2 and the bracket support plate 10. The fork shakes during walking and operation. When the whole machine vibrates greatly, objects may fall. cause danger

[0005] 2. Area A of the L-shaped hook plate 9 on the back of the fork is prone to cracking

Due to the complicated working conditions, when the fork 2 was inserted, it was found that the rock could not move, and I wanted to recover the fork. When driving in reverse, the A area on the rear side is easy to crack

[0006] 3. When the whole machine is bumpy, due to the heavy weight, it will shake together with the fork 2, and the A area of ​​the L-shaped hook plate is easy to crack, causing the driver to worry about potential safety accidents at any time
