Abstract

The invention provides a torsion-resistance and shock-absorption support with natural vibration frequency adjustable. The torsion-resistance and shock-absorption support comprises a top plate, a sliding groove and two sets of elastic shock-absorption blocks, wherein a first pivoting part is downwards formed in the middle of the top plate, the sliding groove is opposite to the top plate, a second pivoting part is upwards formed in the middle of the sliding groove, and the first pivoting part is pivoted to the second pivoting part through a pivoting shaft; the shock-absorption blocks are elastically supported and slidably arranged between the top plate and the sliding groove, and the two sets of shock-absorption blocks are located on the two sides of the pivoting shaft respectively. The shock-absorption blocks play a role in vertical shock absorption, and the shock-absorption blocks are matched with the pivoting shaft to achieve the effect of torsional buffering, so that the shock-absorption performance is greatly improved; the shock-absorption blocks are arranged in the sliding groove in a sliding mode, the position of the shock-absorption blocks in the sliding groove is adjusted tochange the distance between the shock-absorption blocks and the pivoting shaft, and then the rotation rigidity of the shock-absorption support is changed. Therefore, the shock-absorption effect can be greatly improved, and the rotating rigidity and the shock-absorption performance can be adjusted according to the actual condition of transportation materials.

Description

technical field

[0001] The invention relates to the field of transportation equipment, in particular to a torsion-resistant and shock-absorbing support with adjustable natural vibration frequency. Background technique

[0002] In the transportation of boards, for example, during the transportation of prestressed double T boards, the double T boards are generally placed on two sleepers, so the double T boards are four-point load-bearing. Due to the bumpy vehicle and the double T boards are stressed at four points, The double T plate is subjected to torsion, which causes cracks at the junction of the flange and the rib beam. This phenomenon is especially serious when the flange plate is thin and the span is large.

[0003] Therefore, it is necessary to provide a solution to solve the technical problem of board body damage caused by vehicle bumps in the existing board body transportation technology. Contents of the invention

[0004] In order to solve the technical problem o...
