Description

Lifting device for side baffle plate of paver

technical field

The invention relates to a lifting device for a paver side retaining plate, which belongs to the technical field of paver.

Background technique

Paver is a kind of construction equipment mainly used for paving various materials on the base course and surface course of the expressway. During paving construction, according to the width of the construction road surface, it is necessary to carry out various width combinations of the screed assembly and ensure the flatness of both sides of the paving material. Install side baffles on both sides.

The screed side baffle structure often used in the prior art is shown in Figure 1, the front baffle 2' is fixed on the box body 1', the fixed plate 3' is fixed on the front baffle 2', and the side baffle 4' It is fixedly connected with the sliding plate 5', and the sliding plate 5' is installed in the chute of the fixed plate 3' to realize the smooth movement of the side baffle 4'. By turning the handle 7', the transmission screw is driven to rotate, so that the side baffle 4 'Drive the sliding plate 5' to move along the chute of the fixed plate 3' to realize the adjustment of the width.

The disadvantage of the side fence 4' with the above structure is that the side fence 4' is fixedly connected to the sliding plate 5' and then integrally connected to the front plate of the screed. The device is easily deformed; the distance between the two side baffles 4' has a maximum value, and when the width of the road surface is greater than the maximum value, the road surface outside the two side baffles 4' cannot be paved with asphalt and other substances, resulting in the above-mentioned screed The assembly and the side baffle 4' cannot adapt to the road surface; in addition, the side baffle cannot be adjusted up and down as a whole, and the outer surface of the lower part of the screed is prone to material leakage, which cannot meet the needs of paving with different thicknesses.
