Combination wishbone truck

Abstract

The invention discloses a combined fork arm van. The combined fork arm van is mainly composed of a van body part, a lifting arm rest part and a combined fork arm part. A lifting mechanism composed of a main arm and a movable arm is installed on the van body. The combined fork arm part is composed of fork arms, fork arm sets, fork arm lifting devices, fork arm pushing devices, hanging frames and a control system. Forked carrying can be conducted no matter whether the lower sides of objects are provided with fork inserting space or not. Each fork arm is provided with the corresponding independent lifting device and pushing device. Wide chains are guided into flat sliding ways to push and pull the fork arms to go forwards and backwards. Each fork arm set is provided with the corresponding two fork arms. The two fork arm sets are installed on the van. When goods are forked, a wedge opening in the front end of each fork arm in each fork arm set is inserted into small seams of the lower edges of the carried objects to conduct upward lifting and prying so as to expand the seams, and the other fork arm in each fork arm set is inserted into the expanded seams immediately; the two fork arms in each fork arm set alternately lift the goods to be fixed, descend, go forwards and ascend; and carrying can be conducted after the fork arms are inserted into the lower sides of the goods in a penetrating manner. During unloading, the two fork arms in each fork arm set alternately lift the goods to descend and go backwards until the goods fall to a stacking position.

Description

Technical field [0001] The invention belongs to the field of trucks, especially a combined fork-arm truck. Background technique [0002] Existing bagged objects and box objects, as well as packing and bundling objects, are transported by forklifts, but there are three conditions for forklifts: 1. There must be a fork insertion space under the object. 2. The handling site must meet the necessary space for forklift trucks to enter, exit and turn around. 3. A special "grid pad" should be placed under the bag or box object so that the forklift fork can be inserted into the specific space of the "grid pad". "Grid pads" should also be frequently placed, removed, and stacked in the warehouse. However, in the vast majority of rural areas and cities, manual handling is still the main task. Bags, such as grain bags, seed bags, fruit bags, fertilizer bags, cement bags, various raw material bags, mineral bags, etc., box objects, such as cartons, wooden boxes, plastic boxes, bamboo frames,...

AI Technical Summary

Problems solved by technology

This has resulted in such a situation: First, the forklift cannot fork-load and transfer goods in the narrow aisle

Second, forklifts cannot directly fork-load bagged and box-like objects, packaged, and bundled objects that are not inserted into the fork space below.

For a long time, the handling, loading and unloading of these objects has always been carried out by workers' heavy physical labor, which is very hard, takes a long time, and the work efficiency is also very low
