Abstract

A vibration damping device, comprising a first springy element (3), a guide rod (5) and a mass block (2); the first springy element (3) is connected to the mass block at one end, and connected to the equipment to be dampened at the other end; the guide rod (5) is connected to the equipment to be dampened at the two ends respectively; and the mass block (2) is installed on the guide rod and can reciprocate with the extension and retraction of the first springy element. Also provided is an engineering machinery comprising the damping device. With the technical solution of the present invention, the damping device occupies less space, and has a simple structure and a good damping effect in all directions.

Description

technical field [0001] The invention relates to the technical field of vibration reduction, in particular to a vibration reduction device and construction machinery equipment. Background technique [0002] The vibration of the roadheader is mainly caused by the cutting of coal and rock by the cutting head, and the vibration is relatively large. It is transmitted to the main body through the cutting arm, rotary table and other components, which affects the electronic control system and hydraulic system components installed on the main body. At the same time, it has a great impact on the comfort of the operator of the roadheader. [0003] At present, designers have only installed elastic damping elements on some key components, and have not considered the vibration reduction design of the rotary table of the roadheader, and the vibration reduction effect is limited. However, the structure of the roadheader is compact, and the space for installing the shock absorber is limited...
