Three-gantry system

Abstract

The invention discloses a three-gantry system which comprises an outer gantry, a middle gantry, an inner gantry and a fork, wherein first oil cylinders are arranged on the two sides of the outer gantry; the vertical motion of the middle gantry is driven by the ascending and descending of first stretching rods of the first oil cylinders; the inner gantry is driven to vertically move by a first chain arranged on the middle gantry, so that the fork vertically moves following the inner gantry; a second oil cylinder is arranged in the middle position of the inner gantry along the length direction; and the fork can be driven to vertically move by the ascending and descending of a second stretching rod of the second oil cylinder through a second chain. The three-gantry system provided by the invention can cause an article placed on the fork to ascend and descend by virtue of the driving of a hydraulic system, such as the oil cylinder, so that the carrying for the article is realized, the working efficiency is high, the use cost is low and the requirements of enterprise production and development are met.

Description

technical field [0001] The invention relates to a transport tool, in particular to a tripod system. Background technique [0002] Enterprises often need to move some items to a high place, and generally use manual operations to move up some small and miscellaneous items, but this method of handling is not efficient, and the labor cost is relatively high, which is not conducive to the enterprise At the same time, large-scale handling tools such as forklifts are generally used to transport large items. This type of handling requires a large space around the items being transported, which has certain limitations. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to propose a tripod system. [0004] The technical solution of the present invention is achieved as follows: a three-door frame system includes an outer door frame, a middle door frame, an inner door frame and a cargo fork; the upper part of t...
