Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a fast assembling device for a paving machine ironing board. Background Art

[0002] A paver is a road construction machine with a screed installed at the rear to make the paving material uniform and flat. When the paver is paving on roads of different widths, it is necessary to assemble the screed in time to adjust the width of the overall screed structure and ensure that the adjacent screeds are aligned up and down after assembly to ensure the flatness of the paved road surface.

[0003] For example, in the patent document with patent publication number CN214530071U, a quick connector for mechanically assembled ironing plates of paving machines is disclosed, which includes a first ironing plate and a second ironing plate, the tops of the first ironing plate and the second ironing plate are bolted with mounting plates, the tops of the mounting plates on the opposite sides are provided with grooves, a base is arranged inside the groove, and the base is slidably connected to the mounting plates, a connecting seat is bolted to the top of the base, a fixing seat is bolted to the inner wall of the groove, and the fixing seats are symmetrically distributed, hydraulic rods are bolted to the left and right sides of the connecting seat, the piston rod of the hydraulic rod is bolted to a connecting block, a connecting groove is provided inside the fixing seat, an arc groove is provided on the surface of the fixing seat, the connecting block is located inside the connecting groove and is slidably connected to the inner wall of the connecting groove, the piston rod of the hydraulic rod is slidably connected to the inner wall of the arc groove, the mounting seat is bolted to the left side of the mounting plate, a positioning groove is provided on the right side of the mounting plate, and the mounting seat is slidably connected to the inner wall of the mounting groove.

[0004] According to the existing technical documents, the quick connector can quickly assemble the ironing plate and improve the installation efficiency of the ironing plate. However, the disadvantage is that the clamping fit between the limit block and the limit groove is achieved under the action of the compression spring. However, due to the characteristics of the compression spring itself, the spring itself will not compress and move without the action of external force to drive the limit block to move out of the limit groove. At the same time, since the compression spring, the limit block and the limit groove are all arranged inside the positioning groove, there is no space that can provide external force for operation. Therefore, after the ironing plate is quickly assembled, it is difficult to disassemble it later. Secondly, the quick connector lacks an effective leveling structure, and it is difficult to ensure the vertical alignment of adjacent ironing plates after assembly.

[0005] To this end, the utility model optimizes and improves the structural leveling effect after rapid assembly of the ironing board and the subsequent rapid disassembly in the prior art, and hereby proposes a device that can achieve rapid assembly, rapid disassembly, and rapid and accurate leveling, so as to better solve the problems in the prior art.
