Precision instrument device buffering shock absorbing transport semitrailer

Abstract

The invention relates to a precision instrument device buffering and shock absorbing transport semitrailer.Through mutual cooperation and complement of three layers of buffering and shock absorbing, buffering and shockabsorbing of a precision instrument device are completed from different angles taking into account particular emphasis, a first layer of bufferingand shock absorbingpasses through a gooseneck, vertical vibration between a tractor and a gooseneck connection part of a load trailer is reduced, and the vibration in the travelingdirection between the tractor and the load trailer is also reduced; according to a second layer ofbuffering and shock absorbing, through a double shock absorbing suspension system cooperating a suspension lifting cylinder and a torsion bar spring, swaying and impact of the loadtrailer when encountering uneven road surface are retarded, and it can be ensured that the vibrationduring emergency braking is significantly reduced; and according to a thirdlayer of buffering and shock absorbing,through an active buffering mechanismof a device transportation platform, impact and vibration on the precision instrument device in the driving direction during braking of the semitrailer are reduced. The threelayers of buffering and shock absorbing protect the precision instrument device in all directions layer upon layer, and the transportation safety of precision instrument deviceiseffectively protected.

Description

technical field [0001] The invention relates to a shock-absorbing transport semi-trailer, in particular to a shock-absorbing transport semi-trailer for precision instrument equipment, belonging to the technical field of precision instrument transport vehicles. Background technique [0002] With the rapid development of high-tech industries, a large number of precision instruments and equipment have emerged. Precision instruments and equipment not only bear the important mission of supporting the latest technological progress, but also meet the needs of many industrial strategic developments. The precision instrument and equipment manufacturing industry is developing rapidly. Large-scale high-end precision equipment It is no longer limited to a few cutting-edge fields, it has gradually expanded to many fields of the national economy, and the application scale has also increased year by year.

AI Technical Summary

Problems solved by technology

[0003] Precision instruments and equipment need transport vehicles for long-distance, fast and safe transportation from the production workshop to the assembly site, and from one application site to another application site. Precision instruments and equipment have high environmental requirements during transportation, especially for transportation. However, in view of the complexity of road conditions, such as speed bumps, bumpy roads, slope roads, sudden braking and sharp turns, the transport vehicles of the prior art cannot well meet the long-distance requirements of precision instruments and equipment. Expedited Shipping Requirements

[0004] On the whole, the prior art mainly has the following defects: one, in order to adapt to the universality of long-distance transportation, the transportation of the precision instrument and equipment transport vehicle is carried out on the basis of the semi-trailer structure, but the ride comfort of the large semi-trailer of the prior art The design mainly considers the comfort of the driver, that is, the root mean square value of the weighted acceleration at the cab seat does not exceed the specified value, and does not consider the impact of vibration during long-distance transportation on precision instruments and equipment; For semi-trailers of instruments and equipment, in order to ensure that the precision instruments and equipment transported on them are not damaged due to vibration and impact during long-distance driving, the semi-trailers of preci
