Abstract
The utility model belongs to the road surface machinery, and relates to a screed part for road surface pavers, in particular to a dual-layer screed for road surface pavers. The screed comprises a frame fixedly connected with the vehicle body of the road surface paver, a front screed and a rear screed arranged in the front part and the rear part of the frame respectively. The frame is equipped with two upright fixed baffle plates on the right side and the left side respectively, and the baffle plates are equipped with a horizontal hydraulic cylinder on the internal sides respectively. The hydraulic cylinders are so positioned as to correspond to the front screed and the rear screed respectively, and the front ends of the hydraulic pushing rods of the hydraulic cylinders are separately connected with the sides of the inner ends of the front screed and the rear screed respectively. The utility model is capable of adjusting the working width of the screed within a certain scope to fulfill the requirement for construction on different road surfaces, with the advantage of flexible and reliable actions.
Description
Technical field
The utility model belongs to pavement construction machinery, relates to a kind of screed parts of sub-base grader, the double-deck screed of particularly a kind of sub-base grader.
Background technology
The screed of sub-base grader, it mainly acts on is to guarantee that the planeness on road surface in road construction and compactness can reach construction requirement.The screed of existing sub-base grader is the single-layer type structure, and its width is fixed, and is difficult to adapt to the construction requirement on different in width road surface.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of working width conveniently to regulate, with the double-deck screed of the sub-base grader that adapts to the requirement of different in width pavement construction.
The double-deck screed of sub-base grader of the present utility model include a frame of fixedlying connected with the paver vehicle body and in frame before and after screed behind preceding screed of layout and, the frame left and right sides is two fixed dams that heavily fortified point is straight, the hydraulic cylinder of a level respectively is installed two fixed dam inboards, the position of two hydraulic cylinders is corresponding with forward and backward screed position respectively, the hydraulic push rod front end of two hydraulic cylinders is connected on the sidewall of forward and backward screed the inner, can drive front and back, the left and right telescopic moving of screed by hydraulic cylinder.In addition, be fixed with the transverse conduit of level respectively between the two side of forward and backward screed, conduit cooperates with pilot hole on the fixed dam, plays guide effect in the moving process of screed.
The utility model can be regulated the working width of screed within the specific limits, thereby can adapt to the requirement of different in width pavement construction owing to adopted the telescopic double-layer structure, and it is by Driven by Hydraulic Cylinder and catheter directed simultaneously, flexible movements, reliable.
Description of drawings
Fig. 1 is a Facad structure schematic diagram of the present utility model;
Fig. 2 is that Fig. 1 is the plan structure schematic diagram.
The specific embodiment
As shown in the figure, the double-deck screed of sub-base grader of the present utility model includes a frame 1 of fixedlying connected with the paver vehicle body, forward and backwardly in frame be furnished with screed 3 behind a preceding screed 2 and, horizontal duct 5 on two screeds cooperates with pilot hole on the frame both sides fixed dam 4, two fixed dams, 4 installed inside have hydraulic cylinder 6, and hydraulic push rod 7 front ends of hydraulic cylinder are connected on the sidewall of two screed the inners.When hydraulic push rod outwards ejects, promote the inside indentation of level under the guiding of conduit of two screeds, when hydraulic push rod moved in cylinder, it was protruding then to spur two screed levels, thereby reached the purpose of regulating screed overall work width.
Claims (2)
1, the double-deck screed of a kind of sub-base grader, include a frame of fixedlying connected (1) with the paver vehicle body, it is characterized in that: be furnished with screed (3) behind a preceding screed (2) and before and after in frame (1), the frame left and right sides is two fixed dams (4) that heavily fortified point is straight, the hydraulic cylinder (6) of a level respectively is installed two fixed dam inboards, the position of two hydraulic cylinders is corresponding with the position of forward and backward screed (2,3) respectively, and the hydraulic push rod of two hydraulic cylinders (7) front end is connected on the sidewall of forward and backward screed the inner.
2, the double-deck screed of sub-base grader according to claim 1 is characterized in that: be fixed with the conduit (5) of level between the two side of forward and backward screed (2,3) respectively, conduit (5) cooperates with pilot hole on the fixed dam (4).
