Self-locking pre-stress buffering device

Abstract

The invention discloses a self-locking pre-stress buffering device. The self-locking pre-stress buffering device comprises a cover plate top beam arranged at the top of a cover plate, wherein a pre-tightening steel rope is arranged on the lower part of the cover plate top beam; the two ends of the pre-tightening steel rope are respectively connected with the two ends of the cover plate top beam; the pre-tightening steel rope is provided with a tensioning device; the tensioning device is used for applying a pre-stress to the cover plate top beam by pulling the pre-tightening steel rope so that the middle part of the cover plate top beam protrudes upwards. The applied pre-stress can effectively cancel out one part of weight of the cover plate so as to avoid phenomena that the cover plate top beam 1 is broken down by the weight of the cover plate and the deformation which cannot be self-recovered is caused. According to the self-locking pre-stress buffering device, a first force distribution arm and a second force distribution arm are arranged between the cover plate top beam and a cover plate bottom beam; the first force distribution arm, the second force distribution arm and the two sides of the cover plate are distributed at equal distances; the two sides of the cover plate are provided with vertical beams and the support between the cover plate top beam and the cover plate bottom beam is composed of the two vertical beams, the first force distribution arm and the second force distribution arm. The self-locking pre-stress buffering device has the advantages of applying the pre-stress to the cover plate top beam and preventing the cover plate top beam from being deformed.

Description

technical field [0001] The invention relates to the technical field of vehicle components, in particular to a buffer device applied to a vehicle cover, in particular to a self-locking prestressed buffer device. Background technique [0002] With the development of the economy, there are more and more road transport vehicles. In order to deal with the pollution caused by transport vehicles, due to the pollution on the road surface, the high-speed truck tires roll over the pollutant particles on the road surface instantly, and instantly generate high pressure. It will explode in a short time and fission to produce a large amount of fine dust, which diffuses into the air, floats for a long time and cannot fall back to the ground to pollute the air. This is PM2.5; therefore, these pollutant particles are the main cause of urban smog. In order to cure the root cause; Each transport vehicle is equipped with a roof. The top cover installed on the transport vehicle needs to have su...

AI Technical Summary

Problems solved by technology

When the top cover is opened, the top cover is removed from the roof cross beam, and without the support of the roof cross beam, the weight of the top cover will cause a lot of pressure on itself. Bend at

This situation is especially obvious if the metal roof is installed on a transport vehicle with a long trunk: when the roof falls, the stress concentrates on the upper cover beam, especially the middle part of the cover beam is the most stressed, and it is difficult to bear the cover. The weight of the board itself is easy to bend and deform downwards
