Abstract

A pin shaft mounting device suitable for a small space and a using method are disclosed. The device comprises a pin shaft bracket arranged between a left lug plate and a right lug plate, a pin shaft is placed on the pin shaft bracket, a plurality of lug seat holes used for mounting a hydraulic oil cylinder are formed in the pin shaft bracket, and a guide rod of the hydraulic oil cylinder is connected with a pin pulling bolt at the end of the pin shaft. The device further comprises a lifting chain used for lifting the pin shaft. According to the pin shaft mounting device suitable for the small space and the using method, the hydraulic oil cylinder lever is connected with the pin pulling bolt at the end of the pin shaft, the cylinder body end of the hydraulic oil cylinder is connected with the support, when the hydraulic oil cylinder guide rod stretches out, thrust is transmitted to the pin pulling bolt, the pin pulling bolt pushes the pin shaft, friction force of a lug hole and the pin shaft is overcome for pin shaft mounting, by means of the hydraulic principle, the problems of small-space and large-thrust installation and disassembly of the pin shaft are solved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a pin shaft installation device suitable for small spaces and a method for using it. Background technique [0002] Pin shaft connection is a commonly used connection method in mechanical equipment. It has the advantages of simple structure, convenient installation and disassembly, and convenient maintenance of equipment. For example, when we install a tower crane, the connection between the standard section and the standard section, and the connection between the boom and the boom are all connected by pin shafts. The limitation of the pin shaft connection is more obvious. However, due to the limited space of the pin shaft connection, the traditional installation method can no longer meet the installation and disassembly of the pin shaft. For example, use a copper rod or a copper hammer to smash the end of the pin shaft to install and disassemble the pin shaft, or ...
