Description

Technical Field

[0001] The utility model relates to the field of asphalt pavement construction, in particular to a leveling device for asphalt pavement construction. Background Art

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. During the early use of asphalt pavement, a large number of potholes will be produced, which will cause the flatness of the road surface to deteriorate. At this time, the road surface needs to be constructed to level the asphalt pavement.

[0003] In the prior art, asphalt pavement leveling is often carried out with cold asphalt as raw material. Cold asphalt, also known as cold-mix high-strength asphalt concrete, is formed by adding thermosetting resin to asphalt and adding an appropriate amount of solvent to form a semi-fluid asphalt binder. This cold asphalt not only has high strength, but also can greatly shorten the time required for leveling. When using cold asphalt to level the road surface, the cold asphalt material must first be poured into the pit, and the paving board must be installed on the bucket of the loader. The loader then drives the paving board to push through the pit to complete the leveling of the asphalt pavement. At the same time, two sets of side panels are symmetrically arranged on the surface of the paving board. The side panels can prevent the paving board from pushing over the cold asphalt material in the pit, causing the cold asphalt material to overflow from the pit from both sides of the paving board, and the distance between the two sets of side panels is adjustable to accommodate pits of various sizes.

[0004] However, when adjusting the distance between the side panels in the prior art, the positions of the two side panels need to be adjusted separately, and it is difficult to ensure that the two side panels can maintain symmetry with the middle line of the paving board as the symmetry axis.

[0009] Preferably, a shaft ring is sleeved on the shaft body of the gear shaft, one end of the shaft ring abuts against the surface of the paving board, and the other end of the shaft ring abuts against the surface of the gear.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The leveling device for asphalt pavement construction proposed by the utility model, when adjusting the distance between the two groups of front clamping plates, first loosen any one group of adjusting nuts at both ends of the two groups of adjusting bolts, and then move a group of front clamping plates corresponding to the first rack to adjust the position of the group of front clamping plates, the movement of the front clamping plates drives the bottom plate at the bottom end of the front clamping plates and the adjusting bolts in the adjusting groove to move, the movement of the bottom plate simultaneously drives the side plates and the rear clamping plates at the top end of the group of bottom plates to operate, the movement of the side plates adjusts the position of the group of side plates, and the movement of the rear clamping plates makes the first rack move in the same direction, the movement of the first rack makes the gear rotate on the gear shaft, the rotation of the gear makes the second rack move in the opposite direction of the first rack, and the movement distance of the second rack is equal to that of the first rack, the movement of the second rack makes the other group of side plates get the position adjustment in the opposite direction and the same distance, so that the leveling device for asphalt pavement construction only needs to adjust one group of side plates to adjust the other group of side plates accordingly, and can ensure that the two groups of side plates are always symmetrically distributed about the paving plate.
