Abstract

The invention discloses a rapid pin disassembling and assembling mechanism, a disassembling and assembling tool and a disassembling and assembling method in the field of pins. The rapid pin disassembling and assembling mechanism comprises a first base body, a second base body and a pin; the pin is assembled in pin holes of the first base body and the second base body; and one side of a connecting plate is connected with the pin through a first bolt, and the other side of the connecting plate is connected with the first base body through a second bolt. According to the mechanism, the tool and the method, a hydraulic cylinder of the assembling and disassembling tool pushes the pin to act to complete assembling, and rapid pin assembling and disassembling are achieved through the special structural form and mutual size matching of the pin, a limiting plate and the assembling and disassembling tool.

Description

technical field [0001] The invention belongs to the technical field of pin shafts, and in particular relates to a quick disassembly and assembly pin shaft mechanism, a disassembly tool and a disassembly method. Background technique [0002] At present, the main connection methods used in the assembly of construction machinery are bolt connection and pin connection. The pin connection is mostly used for the connection of large load-bearing structural parts such as working arms and hydraulic cylinders, such as excavators, scrapers and other construction machinery products. . During the installation and disassembly of conventional pin connections, different types of tools and special tooling are required for different structural components, and most of them are carried out in the workshop. If it is disassembled outdoors, there are many inconveniences, and it is even difficult to realize pin assembly. At present, natural disasters occur frequently in our country. For disasters...
