Abstract
The invention provides a lifting oil cylinder of an empty container forklift. The lifting oil cylinder comprises a cylinder body, a piston rod, a piston assembly, a first guide part, a second guide part and a fixing part, wherein the piston rod is movably arranged in an installation cavity in the axial direction of the cylinder body, one end of the piston rod extends out of the installation cavity, and a rod cavity extending along the axial direction of the piston rod is defined in the piston rod; the piston assembly is arranged in the installation cavity and is connected with the other end of the piston rod, and a piston cavity which extends along the axial direction of the piston assembly and penetrates through the rod cavity is defined in the piston assembly; the first guide part is formed into an annular part, and the first guide part is arranged in the installation cavity and sleeves one end of the piston rod; the second guide part is formed into an annular part, the second guide part is arranged in the installation cavity, and the second guide part is adjacent to the first guide part and arranged on the piston rod in a sleeving mode; and the fixing part is formed into an annular part, and at least a part of the fixing part abuts against the first guide part and the cylinder body and is connected with the outer wall surface of the cylinder body. The lifting oil cylinder for the empty container forklift is simple in structure, raw materials are saved, and the lifting oil cylinder is convenient to install and locate.
Description
technical field [0001] The invention relates to the technical field of oil cylinders, in particular to an empty truck lifting oil cylinder. Background technique [0002] The specifications of the lifting cylinders currently used by empty container stackers are almost all cylinder diameters of 125mm, rod diameters of 110mm, operating pressure of 23MPa, and lifting capacity of about 20T. This structure meets the needs of general port equipment manufacturers. However, in some cases, it is necessary to increase the lifting capacity of the lifting cylinder, thereby improving the lifting capacity of the entire vehicle, but the operating pressure cannot be increased. The only solution is to increase the diameter of the rod. With the increase of the diameter of the rod, the structure of the original empty box car must be redesigned. Contents of the invention [0003] In view of this, the present invention provides an empty container truck lifting oil cylinder, which has a simple ...
