Abstract

The invention provides a pin assembling and dissembling device, which comprises a gantry, a support and a hydraulic cylinder. The support is connected below the gantry and provided with a lifting portion used for lifting a pin, and the hydraulic cylinder is fixedly connected to the gantry and is provided with a piston which is retractably connected with the pin in a driving manner. The pin assembling and disassembling device has the advantages that assembling and disassembling of the pin are integrated, stable transmission is realized by using power of a pump station, and the pin assembling and disassembling device is compact in structure, fine in universality and applicable to assembling and dissembling of various pins of cranes.

Description

technical field [0001] The invention relates to the fields of mechanical engineering and cranes, in particular to a pin loading and unloading device. Background technique [0002] In the prior art, when the main arm pin shaft of a crane is installed, the pin shaft is manually placed in the pin hole, the pin shaft is connected with a rope, and then the pin shaft is knocked into the pin hole by knocking. [0003] figure 1 A crane pin assembly device in the prior art is shown in . figure 1 Among them, when installing the pin shaft 22 of the part to be installed 21, the pin shaft 22 is hung up with a rope 23, and the part to be installed is loaded into by manual knocking. [0004] The disadvantages of the prior art include: (1) manual disassembly and assembly is time-consuming, labor-intensive, and inefficient; (2) there are hammer marks on the end surface of the pin shaft, which affects the appearance quality; (3) aerial work has potential safety hazards. Contents of the in...
