[0004] The disadvantage of the side baffle 4' with the above structure is that the side baffle 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, so it is necessary to configure this side baffle The screed of the board has low reliability and narrow application range

Embodiment Construction
[0024] The present invention will be further described below in conjunction with accompanying drawing.
[0025] Such as figure 2 As shown, a paver side baffle lifting device includes a hook 2 welded on the baffle 1, a number of sliding sleeves 4 installed on the bracket 6, and a wire rope 5 wound on the sliding sleeve 4, One end of the wire rope 5 is equipped with a chain 3, the hook 2 is hung on the chain 3, and also includes a support box, a threaded rod 21 and a slide block 10, the threaded rod 21 is installed in the support box, and the threaded rod 21 is provided with a limiting structure to limit the screw thread The axial movement of the rod can simultaneously make the threaded rod rotate around its own axis in the support box. The slider 10 is sleeved on the threaded rod 21 through a threaded connection, and the other end of the steel wire rope 5 is connected to the slider 10 .
[0026] The device can drive the slider 10 to move up and down by rotating the threaded r...

The invention discloses a side baffle lifting device for a paver. The side baffle lifting device comprises a hook (2) welded on a baffle (1), a plurality of sliding sleeves (4) arranged on a bracket (6) and a steel wire rope (5) connected to the sliding sleeves (4) by winding, wherein a chain (3) is arranged at one end of the steel wire rope (5), and the hook (2) is hung on the chain (3); the side baffle lifting device further comprises a supporting box body, a threaded rod (21) and a sliding block (10), wherein the threaded rod (21) is arranged in the supporting box body, and provided with a limiting structure for limiting the axial movement of the threaded rod and enabling the threaded rod to rotate around self axis in the supporting box body at the same time; the sliding block (10) sleeves the threaded rod (21) by threaded connection; and the other end of the steel wire rope (5) is connected to the sliding block (10). The side baffle lifting device can realize quick and smooth lifting of a side baffle to meet the paving requirements of different widths and different thicknesses, and is simple and convenient in operation.
Description
technical field [0001] The invention relates to a lifting device for a paver side retaining plate, which belongs to the technical field of paver. Background technique [0002] 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. [0003] The screed side baffle structure often used in the prior art is as follows: figure 1 As shown, the front baffle 2' is fixed on the box body 1', the fixed plate 3' is fixed on the front baffle 2', the side baffle 4' is fixedly connected with the sliding plate 5', and the sliding plate 5' is installed on the fixed plate 3' in the chute to realize the smooth movement of the side baffle 4'. By turnin...
