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.

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 precision instruments and equipment have a very high impact on the cushioning and shock absorption of goods during transportation. requirements, the longitudinal and lateral acceleration numerical indicators of the semi-trailer and precision instruments and equipment are all limited in detail, and it is difficult for the common traction pin traction semi-trailer of the prior art to meet this requirement; the third is the suspension of the transport semi-trailer of the prior art. Generally, the design is only a simple single shock-absorbing suspension system, which has very limited shock absorption, balance and buffering effects, and cannot effectively slow down the shaking and impact caused by bumps when the load-carrying trailer encounters uneven roads during transportation. The vibration is very large, and the design of the suspension system cannot well protect the precision instruments and equipment; Fourth, there is no equipment transportation platform specially designed to protect precision instruments and equipment, and there is no active buffer control through the equipment transportation platform. The shock device has a poor buffering effect during the typical braking process of the semi-trailer, and cannot reduce the braking impulse and deceleration speed. It has a large impact and vibration on precision instruments and equipment in the driving direction. The protection of precision instruments and equipment in the horizontal direction is very limited and cannot meet the requirements at all
