Quick disassembly and assembly device for heavy-duty vehicle track

Abstract

The invention discloses a quick disassembly and assembly device for a heavy-duty vehicle track. A sleeve disassembling screw corresponding to an end coupling fixing screw is sleeved on an output shaft of a doubling spanner; and a pull claw bracket only provided with an internal thread is screwed on a hydraulic cylinder, one end of each of two pull claws is connected to the pull claw bracket, and the other ends of the pull claws are connected by using threads through a pull block with a proper size respectively and arranged on a track end coupling; and during working, a thin ejection rod fixed on an ejection piston rod provided with the hydraulic cylinder is ejected from a screw hole of the end coupling, and then the rear end of the hydraulic cylinder is shaken to add hydraulic oil into an ejection cylinder so as to push the ejection piston rod to advance and eject a blocking pressure block on the end coupling. The other pull claw bracket only provided with an internal thread is screwed on a hydraulic cylinder, one end of each of two pull claws is connected to the pull claw bracket, and the other ends of the pull claws are connected by using threads through a connecting pull plate with a proper size respectively; and during working, the ejection end provided with hydraulic cylinder is ejected on two shaft pins of the track through two symmetrical ejection rods, the connecting pull plate is inserted into a gap between two track plates, two ends of the connecting pull plate are connected to the two pull claws through bolts, and then the rear end of the hydraulic cylinder is shaken to add hydraulic oil into the ejection cylinder so as to push the ejection piston rod to advance and fulfill the purpose of pulling out the end coupling.

Description

technical field [0001] The invention relates to a dismounting and installing device for track maintenance, especially capable of playing an important role in the repair and maintenance of heavy-duty vehicle tracks. The same content has applied for a utility model patent. Background technique [0002] At present, there is no special tool for the removal of heavy-duty equipment tracks. The disassembly of the end coupler is basically by knocking or destructive cutting, which is time-consuming and laborious, and is restricted by various conditions such as site, equipment, and energy. Even if the end coupler is removed , Track shoes and other components have also been damaged to varying degrees, especially in the repair and maintenance of the tracks of amphibious heavy-duty vehicles soaked in corrosive liquids such as seawater. Contents of the invention [0003] In order to overcome the deficiency that existing tools cannot quickly remove the crawler end coupling without damag...
