Supporting device for tensioning structure of engineering machinery vehicle

Abstract

The invention relates to the technical field of engineering vehicles, in particular to a supporting device for a tensioning structure of an engineering machinery vehicle. The supporting structure comprises a supporting frame, a limiting block, a threaded part, a connecting rod, a straight threaded barrel, a connecting disc, a first connecting ring, a second connecting ring and pin columns; the straight threaded barrel is connected to a part needing to be tensioned through the connecting disc, accordingly, when a tensioning spring and other components need to be maintained and replaced, if thetensioning spring is in a compressed state, bolts between the first connecting ring and the second connecting ring are disassembled firstly, then a lengthened sleeve is installed on the pin columns onthe connecting rod in an inserting mode, then the connecting rod is rotated through the lengthened sleeve, thus, the length of the portion, in the straight threaded barrel, of the threaded part is shortened, therefore, the length of a connecting piece composed of the straight threaded barrel and the connecting rod is increased, and namely, the distance between the limiting block and a through hole is increased; and accordingly, the tension force of the tensioning spring is released, the situation that the tensioning spring hurts people is avoided, safety is improved, and disassembling of thetensioning spring and other components is facilitated.

Description

technical field [0001] The invention relates to a support device for an uplift structure of an engineering machinery vehicle, which belongs to the technical field of engineering vehicles. Background technique [0002] The tension spring is one of the main components in the buffer system of the vehicle tensioning assembly of Cheng Machinery. At present, the length of the connecting piece inserted in the tension spring is fixed. During the maintenance and replacement process, if the tension spring is in a compressed state, it is difficult to release it. The gravitational force of the tension spring not only increases the difficulty of disassembling the parts, but also causes the parts to collapse and injure people due to the failure of the gravitational force to be released during the forced disassembly process, posing a safety hazard. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a support ...
