Damping protection device for mechanical equipment

Abstract

The invention discloses a damping protection device for the mechanical equipment. The damping protection device for the mechanical equipment comprises a supporting plate, wherein a plurality of groups of guide sliding rods are symmetrically and glidingly inserted and arranged onto the supporting plate; and a protection plate and a synchronous plate are jointly and fixedly installed at the upper ends and the lower ends of the plurality of groups of guide sliding rods; an air cylinder sliding block is slidably installed on the section, located above the supporting plate, of each group of the guide sliding rods; detection cylinders are symmetrically and fixedly installed on the supporting plate; and the upper end of each detection cylinder slidably penetrates through an air cylinder sliding block and is slidably provided with a supporting rod in an inserted mode; and the upper end of each supporting rod extends to the position above the protection plate and is provided with an assembling plate. The vibration amplitude change is detected, the force opposite to the vibration direction is provided, and the elastic force of a damping spring is changed, so that the vibration amplitude of the mechanical equipment is reduced, i.e., the active damping function is achieved; and the adjustable active protection function is achieved through contact detection on the vibration amplitude, and the influence of strenuous vibration on the mechanical equipment is reduced.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a shock absorbing protection device for mechanical equipment. Background technique [0002] Existing shock protection devices for mechanical equipment usually use spring or hydraulic passive shock absorption, that is, through the elastic characteristics of the spring or the compression characteristics of the hydraulic fluid, the vibration is converted into internal energy storage and release, but the spring or hydraulic passive When energy storage is used for shock absorption, displacement will occur, that is, the larger the vibration amplitude, the greater the displacement distance. The larger vibration amplitude will affect the working status of mechanical equipment, causing vibration damage to mechanical equipment, and there are many factors in mechanical equipment. When the vibration amplitude increases, it cannot protect and stop the mechanical equipment in time. Conten...
