Description
Technical Field
The utility model relates to a transport vehicle assembly, in particular to a vehicle ladder and a low-flat transport vehicle thereof.
Background
The vehicle ladder is a key part of a low-flat transport vehicle and plays a role in the up-and-down of a transported engineering vehicle. When transportation starts, the crawling ladder is placed on the ground, the transported engineering vehicle is driven by a driver to climb onto the low flat plate vehicle from the ground, the low flat plate vehicle transports the engineering vehicle form after the crawling ladder is lifted, the crawling ladder is placed after the transported engineering vehicle is transported to a destination, and the transported engineering vehicle is driven by the driver to climb onto the ground from the low flat plate vehicle.
The existing ladder stand component is mainly formed by welding parts such as ladder stand longitudinal beams, cross beams and the like. As shown in fig. 1 and 2, the conventional vertical ladder beam is formed by welding an arc-shaped front sealing plate, a longitudinal beam upper wing plate, a web plate, a lower wing plate and a reinforcing vertical rib, and the cross section of the conventional vertical ladder beam is similar to a groined shape, is similar to a box girder structure, and has more welding surfaces. The box-type beam structure needs to be assembled and welded one by one when the wing plates and the abdomen are assembled and welded, and the production efficiency is low. Four welding seams are long, and the labor intensity of workers is high.
In order to solve the above problems, people are always seeking an ideal technical solution.
SUMMERY OF THE UTILITY MODEL
In order to achieve the purpose, the utility model adopts the technical scheme that: a vehicle ladder stand comprises a plurality of ladder stand longitudinal beams, wherein two adjacent ladder stand longitudinal beams are connected through a plurality of cross beams, one end of each ladder stand longitudinal beam is provided with a turning shaft mounting hole, and a turning shaft penetrates through the turning shaft mounting holes; a spring fixing beam is also arranged between the ladder stand longitudinal beams;
the ladder stand longitudinal beam comprises a U-shaped stamping part, one end of the U-shaped stamping part is connected with an arc front sealing plate, an upper wing plate of the longitudinal beam is welded to the top of the U-shaped stamping part, and two ends of the cross beam are fixed to two side walls of two adjacent U-shaped stamping parts respectively.
Based on the above, the turnover shaft mounting hole is formed in the arc-shaped front sealing plate.
Based on the above, many crossbeams all with the cat ladder longeron sets up perpendicularly.
Based on the above, the length of the turnover shaft is greater than that of the cross beam.
The utility model also provides a low flat transport vehicle which comprises a low flat transport vehicle frame, wherein the vehicle ladder stand is arranged at the tail part of the low flat transport vehicle frame.
Compared with the prior art, the vehicle ladder stand has substantive characteristics and progress, and particularly, the vehicle ladder stand provided by the utility model has the advantages that the existing welding structural part is replaced by the stamping structural part, the stamping forming can be directly carried out on a die after the cutting and blanking are finished, so that a flat plate is stamped into a U-shaped part, and then the U-shaped part is welded with the cover plate and the front sealing plate. The box type structure is changed into a mode of adding the cover plate to the U-shaped piece, the welding seam is reduced by half, and the production efficiency is improved.
Furthermore, because the U-shaped part belongs to an integrally formed structure, the internal welding stress is less, reinforcing vertical bars in the existing structure can be omitted, the material is saved, and the weight is reduced. Furthermore, the low flat plate transport vehicle provided with the vehicle ladder stand has the advantages of novel structure, smooth appearance, smooth external transition and high operation safety.
