Large-scale optical instrument transportation vibration protection system

Abstract

The invention provides a large-scale optical instrument transportation vibration protection system, and a protection structure form which combines a six-degree-of-freedom vibration isolation device and a four-line pendulum structure is formed. The large-scale optical instrument transportation vibration protection system comprises a vibration protection structure upper part and a vibration protection structure lower part which jointly form a transportation accompanying vibration protection structure, the vibration protection structure upper part is composed of an outer frame structure (3), a vibration isolation catenary unit (1) and a vibration isolation inhaul cable unit (5), the vibration protection structure lower part is composed of a structure base (9), a horizontal and vertical multi-dimensional vibration isolation element (8) and a rack middle connecting plate (7), the large-scale optical instrument transportation vibration protection system further comprises a turnover device and a limiting damping pad (6) which is located on the side face of the turnover device (4) in the vertical direction, the turnover device is a prefabricated part with certain rigidity and bearing capacity, a bolt hole is reserved at the bottom of the turnover device, and the turnover device can be connected with the rack middle connecting plate (7). The large-scale optical instrument transportationvibration protection system has the advantages of being low in inherent frequency, efficient in vibration isolation and high in stability, and the vibration protection problem in the transportation process of large optical instruments can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of transportation vibration protection, in particular to a large-scale optical instrument transportation vibration protection system based on a six-degree-of-freedom vibration isolation platform and a four-wire pendulum vibration isolation device. Background technique [0002] At present, in view of the fact that large-scale precision optical instruments and similar equipment are difficult to effectively remove the joint influence of road surface irregularity impact and continuous vibration in transportation, and the carrying equipment is prone to damage or destruction due to the comprehensive vibration, the generally adopted methods mainly include airbag support and The steel wire rope is fixed, but this measure is difficult to meet the vibration isolation design requirements of the equipment. In short, the defects of traditional technology mainly include the following aspects: [0003] (1) The damping cha...
