Abstract

The invention discloses an engineering machinery shock absorber and a shock absorption method thereof, and belongs to the field of engineering machinery. The engineering machinery shock absorber comprises a base; the upper end of the base is fixedly connected with a buffer sleeve; the inner top of the buffer sleeve is provided with a shock absorption sliding rod slidably connected with the buffer sleeve in a sleeved mode; the shock absorption sliding rod is elastically connected with the inner bottom of the buffer sleeve through a shock absorption spring; the upper end of the shock absorption sliding rod is fixedly connected with a supporting plate; aplurality of circumferentially distributed exhaust ports are arranged on the outer wall of the lower end of the buffer sleeve; an upper circular ring corresponding to the exhaust ports is rotatably connected to the inner wall of a heat dissipation groove; a plurality of circumferentially distributed through holes and a blind hole are arranged on the outer wall of the upper circular ring; a self-cleaning mechanism matched with multiple dustproof nets is arranged in the heat dissipation groove; and a circulating heat dissipation mechanism connected with the self-cleaning mechanism is arranged in the inner wall of the shock absorption sliding rod. According to a shock absorption device provided by the invention, heat dissipation of the shock absorption device can be achieved while mechanical equipment is damped, and the situation of shock absorption failures is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an engineering machinery shock absorber and a shock absorbing method thereof. Background technique [0002] Construction machinery is an important part of the equipment industry. In a nutshell, all the mechanical equipment necessary for comprehensive mechanized construction projects required for earthwork construction projects, road surface construction and maintenance, mobile lifting and loading and unloading operations, and various construction projects are called construction machinery. [0003] In the construction of construction machinery, shock absorbers can effectively buffer the vibration of machinery. At present, the widely used shock absorber is spring shock absorber. The spring generates a lot of heat after working for a long time, and it is prone to shock absorption failure, which affects the shock absorption effect of mechanical equipment, and the serv...
