Description

Technical Field

[0001] This utility model belongs to the technical field of equipment and devices for building new roads and repairing or constructing existing roads, specifically relating to the components of a high-viscosity emulsified asphalt spraying truck. Background Technology

[0002] Thickened and fibrous slurry seal coats are mainly used to treat road surface defects such as reduced friction, cracks, and ruts, in order to improve the anti-skid and waterproof performance of the road surface, improve the smoothness of the road surface and driving comfort, thereby achieving the effect of "rejuvenating the old".

[0003] The tack-bonded micro-surfacing layer involves spraying a tack coat before applying the fiber micro-surfacing layer, followed by the fiber micro-surfacing application. It combines the advantages of both tack coat and micro-surfacing technologies, employing a specialized emulsified asphalt bonding layer technology and equipped with an emulsified asphalt spraying device. This creates a super-strong bonding layer on the old pavement, simultaneously bonding with the fiber-infused micro-surfacing mixture to form an asphalt binder bonding layer with a three-dimensional network structure. This significantly improves the adhesion between the new and old pavement layers, as well as the anti-skid and waterproof properties of the new pavement, thereby extending the pavement's service life and greatly enhancing its overall performance.

[0004] During construction, the high-viscosity emulsified asphalt spraying frame is a specialized device for conveying and spraying tack coat oil. The spraying width of the tack coat oil must be adjusted according to the paving width. The width adjustment needs to be flexible and convenient, and the spraying must be uniform and the spraying volume must be precisely controlled; otherwise, the construction effect will be seriously affected. The original tack coat oil spraying device was difficult to adjust left and right, the spraying volume was not easy to control, the appearance was not protected, and the whole device was easily contaminated.

[0005] The existing spraying frames of viscous and fiber-reinforced slurry seal trucks, fiber-reinforced slurry seal trucks, and emulsified asphalt spraying trucks are not suitable for spraying high-viscosity emulsified asphalt.

[0006] To address the aforementioned technical problems, the inventor of this utility model has designed a high-viscosity emulsified asphalt spraying vehicle. One pressing technical issue that needs to be addressed is providing a spraying frame suitable for spraying high-viscosity emulsified asphalt. Summary of the Invention

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a high-viscosity emulsified asphalt spraying frame that is reasonably designed, simple in structure, has high construction effect and good stability.

[0008] The technical solution adopted to solve the above-mentioned technical problems is as follows: Two sliding tracks are arranged on the left and right sides of the nozzle frame; the cylinders of two lifting cylinders are connected to the nozzle frame, and the piston rods are connected to the high-viscosity emulsified asphalt spraying truck; the nozzle frame is equipped with an oil inlet pipe and an oil return pipe connected to the high-viscosity emulsified asphalt tank on the high-viscosity emulsified asphalt spraying truck; nozzles are arranged in the front row and the rear row on the nozzle frame, and the nozzles are connected to the oil inlet pipe and the oil return pipe; two sliding tracks are arranged on the left and right sides of the nozzle frame, with one track... A rack is provided on the upper part of the fixed bracket; a hydraulic motor is provided on the upper surface of the fixed bracket. The oil inlet of the hydraulic motor is connected to the hydraulic pump on the high-viscosity emulsified asphalt spraying truck through the oil inlet pipe, and the oil return pipe is connected to the hydraulic oil tank on the high-viscosity emulsified asphalt spraying truck. A gear that meshes with the rack is provided on the power output shaft of the hydraulic motor. A pulley block is provided on the upper surface of the fixed bracket and a pulley block is provided on the lower surface. The fixed bracket is placed on two slides, which are located between the pulley blocks on the upper surface and the pulley blocks on the lower surface.

[0009] The present invention has 6 to 12 nozzles arranged in the front row and 6 to 12 nozzles arranged in the rear row on the nozzle frame.

[0010] The present invention preferably has 9 nozzles arranged in the front row and 9 nozzles arranged in the rear row on the nozzle frame.

[0011] This utility model has three sets of pulleys on the front and three on the back of the fixed bracket, with two pulleys installed in each set.

[0012] This invention utilizes a power unit mounted on a fixed support, with front and rear nozzles mounted on the nozzle frame. The power unit drives the nozzle frame to move left and right, increasing the width of the high-viscosity emulsified asphalt spraying. A lifting cylinder is employed to adjust the height of the nozzles on the nozzle frame relative to the road surface, thus adjusting the uniformity of the high-viscosity emulsified asphalt spraying. This invention adjusts the width and uniformity of the high-viscosity emulsified asphalt spraying according to different road widths, improving construction efficiency and reducing construction costs. It can be widely applied in construction projects such as ordinary slurry seal, modified slurry seal, micro-surfacing, fiber-reinforced slurry seal, fiber micro-surfacing, and tackified / fiber-reinforced micro-surfacing.
