Engineering machinery accessory disassembling and assembling tool

Abstract

The invention provides an engineering machinery accessory disassembling and assembling tool, and relates to the technical field of disassembling and assembling tools. The engineering machinery accessory disassembling and assembling tool comprises a support and a cylindrical piece. A penetrating hole is formed in the support, and the cylindrical piece can penetrate through the penetrating hole andcan move in the penetrating hole in the axial direction of the penetrating hole. The support is used for supporting the cylindrical piece so that one end of the cylindrical piece can abut against oneend of a pin shaft between an engineering machinery accessory and engineering machinery. According to the tool, the technical problems that in the prior art, in the process of replacing the engineering machinery accessory, when a copper bar is held by hand to knock out the pin shaft between the accessory and the engineering machinery, labor is wasted, and danger is prone to being caused to workersare solved.

Description

technical field [0001] The invention relates to the technical field of assembly and disassembly tools, in particular to a disassembly and assembly tool for engineering machinery attachments. Background technique [0002] Excavator is a common construction machine, which can be seen in various scenes such as infrastructure construction, earthquake relief, flood fighting and rescue. The working environment of the excavator is very harsh and complex, so the bucket, breaker and other attachments of the excavator are easily damaged. In order not to affect the normal use of the excavator, it is necessary to replace the damaged attachments. [0003] The attachments of construction machinery such as excavators are usually connected together by pins and lugs. Since excavators and other construction machinery have been operating under severe and complicated working conditions, the pin shaft between the attachment and the excavator is easy to wear and collide, and the friction between...

Problems solved by technology

[0005] The purpose of the present invention is to provide a tool for disassembling and installing construction machinery attachments, so as to alleviate the problem in the prior art that when replacing construction machinery attachments, it is usually necessary to first hold the copper rod to align the copper rod with the pin shaft, and then use one or Several people hold the copper rod in their hands, and another person hits the copper rod with a heavy hammer to knock out the pin between the attachment and the construction machinery, then install the new attachment, and then knock the new pin into the new attachment. However, when the pin shaft between the attachment and the construction machinery is knocked out with a hand-held copper rod, it is not only laborious but also likely to cause danger to the staff.
