Description

Technical Field

[0001] The present invention relates to the technical field of pavement construction, and specifically relates to a leveling device for concrete pavement construction. Background Art

[0002] During the process of road construction, the flatness of the road surface is crucial for a road, because the flatness of the road surface directly affects the comfort and safety of driving.

[0003] In the prior art, the leveling of the road surface needs to be carried out by using a leveling device. The road surface leveling device refers to a device that ensures the road surface is relatively flat during the renovation process. Generally, it is used for the renovation of the road surface and has the characteristics of durability, convenience, and easy operation.

[0004] However, traditional concrete pavement leveling devices mostly use a combination of a leveling shovel and a leveling roller to修整 the road surface. However, due to their height being mostly manually positioned, the leveling accuracy is reduced. Moreover, the mud shoveled out during leveling is easy to accumulate and jam the device. At the same time, the mud on the leveling roller cannot be cleaned and utilized during the leveling process, and it is even more difficult to clean after it hardens. Summary of the Invention

[0005] The purpose of the present invention is to provide a leveling device for concrete pavement construction to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A leveling device for concrete pavement construction, including a gantry. A hydraulic rod is installed on the top of the gantry, and the bottom end of the piston rod of the hydraulic rod is fixed to the top of the leveling mechanism. A laser signal receiver is fixed to the top of the gantry. The laser signal receiver cooperates with a laser level, and the laser level is fixed to the top end of the positioning mechanism.

[0007] Preferably, the gantry is in a "C"-shaped frame structure. A pull rod and a controller are fixed to the surface of the gantry, and traveling wheels are rotatably connected to the surfaces of two parallel side plates of the gantry.

[0008] Preferably, the piston rod of the hydraulic rod penetrates through the top plate of the gantry. The leveling mechanism is located between two parallel side plates of the gantry. There are two groups of hydraulic rods, and the two groups of hydraulic rods are symmetrically distributed with respect to the laser signal receiver.

[0009] Preferably, the leveling mechanism includes a leveling shovel, a leveling roller, a moving seat, a limiting slider, a transmission shaft, a feeding blade, a driving motor, a feeding port, a scraping plate, and a positioning shaft. The leveling shovel is in a right-angled trapezoidal frame structure. A suspension frame is fixed to the outer wall of the leveling shovel. The suspension frame is in a "C"-shaped rod structure. The suspension frame movably penetrates through the leveling roller.

[0010] Preferably, both ends of the movable seat are integrally formed with limiting sliders, the limiting sliders are slidably connected in limiting slide grooves, and the limiting slide grooves are provided on the side panels of the gantry.

The base is fixed to the bottom surface of the rod sleeve, the ground nail is fixed to the bottom surface of the base, the telescopic rod is movably inserted in the rod sleeve, the outer wall of the rod sleeve is threaded with a positioning knob, the positioning knob passes through the rod sleeve and clamps the telescopic rod, the mounting seat is fixed to the top end of the telescopic rod, and the laser level is fixed to the top surface of the mounting seat.

[0013] Preferably, a mounting frame is fixed on the surface of the scraper, and two reserved grooves are symmetrically provided on the surface of the mounting frame. Electric telescopic rods are fixed in the two reserved grooves. A traction plate is fixed to the piston rod of the electric telescopic rod. A limiting slide groove is provided on the surface of the traction plate. The limiting slide groove slides along the limiting rail. The limiting rail is an "L"-shaped plate structure, and the limiting rail is fixed to the surface of the scraper.

[0014] Preferably, the surface of the traction plate facing the scraper is provided with multiple groups of mounting grooves, a knocking handle is movably inserted inside the mounting groove, the surface of the knocking handle facing the scraper is an arc-shaped curved surface, and an elastic support plate is fixed between the knocking handle and the mounting groove, the elastic support plate is a "U" plate-shaped structure, and a rubber connecting block is fixed between the elastic support plate and the mounting groove.

When a large error occurs, the hydraulic rod is driven to extend and retract to achieve the purpose of high-precision adjustment. The mud is leveled by a leveling shovel, and excess mud enters the leveling shovel. The driving motor drives the feed blade to rotate and discharge the mud forward, which can effectively prevent the mud from accumulating and jamming the device. After leveling, the mud is flattened by the rotation of the leveling roller, thereby improving the leveling efficiency. The mud attached to the leveling roller is scraped off by the scraper and enters the leveling roller for collection. BRIEF DESCRIPTION OF THE DRAWINGS
