Hydraulic pulsation vertical vibration isolation device

Abstract

The invention relates to a hydraulic pulse-type vertical shock isolating device, which comprises installation base plates, a hydraulic shock isolating unit and supporting springs. The hydraulic pulse-type vertical shock isolating device is characterized in that the hydraulic shock isolating unit and the supporting springs are installed between two installation base plates which are arranged in parallel, the hydraulic shock isolating unit comprises an upper base, a lower base, an upper hydraulic cylinder, a lower hydraulic cylinder and a hydraulic control system, the hydraulic control system consists of a hydraulic source, an oil compensating loop and a shock isolating loop, the upper base and the lower base are arranged in parallel, the cylinder body of the upper hydraulic cylinder is fixed with the upper base, the cylinder body of the lower hydraulic cylinder is fixed with the lower base, piston rods of the upper hydraulic cylinder and the lower hydraulic cylinder are relatively connected together, the cylinder bodies of the upper hydraulic cylinder and the lower hydraulic cylinder are serially connected with each other through the hydraulic control system, and a hydraulic cylinder connecting plate is fixedly arranged between the piston rods of the upper hydraulic cylinder and the lower hydraulic cylinder. The hydraulic pulse-type vertical shock isolating device has the advantages of large damping force, flexible arrangement, quick response, convenience in installation, debugging and maintenance and compact structure, and has supporting and shock isolating dual functions.

Description

technical field [0001] The invention belongs to the field of vibration control of civil engineering structures and the technical field of shock isolation, and relates to a pulsating hydraulic vertical shock isolation device. With vertical stiffness and shock isolation damping force, it can assist in supporting structures and reduce the vibration response of structures during earthquakes, thus playing the role of shock isolation. It is suitable for vertical isolation of industrial and civil buildings, bridge engineering and large-scale and precision mechanical equipment. Background technique [0002] Seismic isolation technology is the most widely used and most mature researched structural vibration control scheme. Seismic isolation technology has relevant content in the building seismic design codes of various countries. At present, most of the seismic isolation technologies generally can only realize the effect of horizontal seismic isolation, and there are relatively few ...
