Combined fork arm of telescopic arm forklift

Abstract

The invention discloses a combined fork arm of a telescopic arm forklift. The combined fork arm is mainly composed of fork arm couplings, two fork arm sets, fork arm coupling lifting devices, fork arm coupling advancing devices, a pallet fork hanging block and a control system, wherein the two pallet forks of the telescopic arm forklift are replaced with the two fork arm sets, which are used for forking and transporting box body type and bag type objects with no space below for pallet forks to insert; each fork arm coupling is composed by connecting one fork handle with one to four fork arms; each fork arm set is composed of two fork arm couplings; each fork arm coupling is provided with an independent set of lifting device and advancing device; when to fork goods, the fork arm front end wedge of one fork arm coupling is inserted into a small gap underneath the goods firstly and pries upwards to enlarge the gap; the fork arm of the other fork arm coupling is immediately inserted into the pried and enlarged gap, and the prying and inserting processes are alternately carried out; the two fork arms are lifted alternately to hold the goods to stay still, descend, advance and ascend till the fork arms penetrate through the underneath of the goods; when to unload the goods, above the placing point of the goods, the two fork arms alternately hold the goods to stay still, descend and retreat till the goods are placed on the placing point.

Description

technical field [0001] The invention belongs to the field of telescopic forklifts, in particular to combined yokes of telescopic forklifts. Background technique [0002] Existing telescopic arm forklift lifts and carries goods, gets on and off the car, stacks and takes off goods in warehouses, transshipment of ground goods, etc., has played a great role. But existing telescopic arm forklift has a very big shortcoming that can only fork lift the object that inserts the fork space below. This is for many bags, such as grain bags, various raw material bags, melon and fruit bags, cement bags, fertilizer bags, etc., stacked together, there is no space below. Although there are grid mats for telescopic arm forklifts that are easy to fork, one layer can be placed every certain number of stacking layers, but most warehouses, especially the vast and scattered grain stations, chemical stations, cement stations, seed stations, fertilizer stations and other warehouses, often There is ...

Problems solved by technology

But the existing telescopic arm forklift has a big shortcoming that it can only fork lift objects that are inserted into the fork space.

There are also many box objects, such as cartons, wooden boxes, melon and fruit boxes, vegetable boxes, baskets, etc., which are often stacked directly layer by layer, ...
