Special automatic vibration reduction and absorption working platform for high-altitude operation car

Abstract

The invention discloses a special automatic vibration reduction and absorption working platform for a high-altitude operation car. The working platform comprises a floating platform, an outer frame, avertical vibration reducer set, a linear bearing, a horizontal vibration reducer set and two connecting beams, wherein the floating platform is embedded in the outer frame, and is fixedly connected with the linear bearing through the vertical vibration reducer set; the linear bearing and a transverse shaft on the outer frame form a slide pair; and the horizontal vibration reducer set is fixed between a linear bearing connecting beam and the outer frame. Through the arrangement of the floating platform which is independent and free of mutual noninterference in the vertical and left-right directions and can reduce and absorb vibration, the vibration transfer between the floating platform and a cantilever crane is effectively inhibited, the vibration amplitude and the vibration speed of theworking platform are reduced, the stability and the safety of the working platform in a working state of the high-altitude operation car are improved, and the improvement of the working efficiency isfacilitated.

Description

technical field [0001] The invention relates to an automatic vibration-reducing vibration-absorbing working platform dedicated to aerial work vehicles, which belongs to the technical field of engineering machinery. Background technique [0002] Aerial work vehicle is a kind of special engineering machinery for carrying people, equipment, etc. for aerial work. It is widely used in fields such as electric power, fire protection, municipal administration, gardens, communications, transportation, and advertising. Its working platform is located at the end of the boom system and directly carries personnel and equipment. It is an important device for the realization of the function of the aerial work vehicle. [0003] When the boom of the aerial work vehicle reaches a certain working height, its stiffness decreases and its flexibility increases. At this time, factors such as mechanical inertia, hydraulic shock, and external disturbances will cause the boom to generate large-scale...

Problems solved by technology

However, this method can only suppress the vibration in the secondary direction, but cannot take into account multiple directions, and it is difficult to produce vibrations in the up, down, left and right directions that are easy to occur and have amplitudes

In fact, even if this elastic damping element is simply reused in multiple directions according to this scheme, it will cause interference in the movement of the working platform in multiple directions, and the vibration damping and damping functions in multiple directions cannot be exerted.
