Abstract

The invention relates to the technical field of pavement construction machinery, and discloses side tensioning devices of screeds as well as a paver. The side tensioning device of the corresponding screed comprises a main body (1), a linear unit (3) and an elastic unit (5), wherein the main body (1) is fixed on the paver; one end of the linear unit (3) is connected to the screed of the paver; andone end of the elastic unit (5) is connected to the main body (1), and the elastic unit (5) can deform under the state of receiving the traction force of the other end of the linear unit (3) and provide the biasing force for the linear unit (3) to restore the deformation direction. According to the side tensioning devices disclosed by the invention, through the deformation change of the elastic units, the positions of the screeds are balanced, and the screeds are prevented from deforming during use.

Description

technical field [0001] The invention relates to the technical field of road construction machinery, in particular to a side tensioning device of a screed and a paver. Background technique [0002] During the construction of the paver, the telescopic screed will deform backward due to the resistance of the material in front, that is, the downward direction in the figure. When the extension length of the telescopic screed is larger, the backward deformation is larger, and the construction quality will be greatly reduced. In order to prevent the backward deformation of the telescopic screed during construction, a side tensioning mechanism is provided. During the construction process, the side tensioning mechanism tightens the end of the telescopic screed through the wire rope, which can effectively prevent the telescopic screed from being deformed backwards. [0003] Such as figure 1 Shown is the structural schematic diagram of the existing paver. Sequence number 16 is body...
