AI Technical Summary
When a forklift transports items of box, the center of gravity is offset due to the different sizes of the boxes, which can easily shake on uneven roads or move the goods to one end when they stop, resulting in the problem of goods sliding down and poor stability.
A forklift lifting safety protection device is designed, adopting multiple hydraulic cylinders and connecting rod structures. The protective plate and connecting rod are moved through the expansion and contraction of the hydraulic cylinder, clamping the items and improving the stability of the items.
Through the clamping mechanism between the hydraulic cylinder and the connecting rod, the position of the protective plate and the connecting rod is adjusted according to the width of the item, improving the stability of the item and preventing the center of gravity from shifting and sliding.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of forklifts, in particular to a forklift lifting safety protection device. Background Art
[0002] As we all know, a forklift is a loading and unloading machine that can effectively combine horizontal transportation and vertical lifting. It has comprehensive functions such as loading and unloading, lifting and transportation. It has the advantages of high work efficiency, easy operation, and flexibility. It is very convenient and effective to store and load goods in the warehouse.
[0003] In real life, when a forklift is transporting box-like items placed on a pallet, the boxes placed on the pallet have different overall widths due to their different sizes. When the width is large, the center of gravity of the boxes located at the edge of the pallet is easily shifted to both sides. Therefore, during the transportation of the boxes on both sides of the pallet, the forklift is driving on an uneven road surface, which may easily cause the box body to shake, or when the forklift stops moving, the goods on the forklift frame may easily move to one end of the forklift due to inertia. The center of gravity of the goods located at the edge of the pallet will shift when moving. The shifted center of gravity of the goods may easily cause them to slide off the lifting frame. Therefore, the stabilization effect of box-like items is not very good. For this reason, a forklift lifting safety protection device is proposed. Utility Model Content
