Description

Technical Field

[0001] The present application relates to the technical field of road construction, and in particular to a hot asphalt spraying device for curbstones. Background Art

[0002] Curbstones are marker stones placed between the road surface and other structures. They are commonly found at the edge of the central dividing strip of a highway, the right edge of a lane, or the outer edge of a shoulder. During the construction process, the junction between the curbstone and the road surface needs to be sprayed with hot asphalt to better connect the two and enhance its waterproof performance.

[0003] Conventionally, when hot asphalt is sprayed, construction workers hold a spray nozzle to spray. This method has higher technical requirements for construction workers. It is not easy to maintain a straight line during the spraying process. In addition, the hot asphalt splashes everywhere, causing pollution to the environment and easily splashing onto construction workers, which is very dangerous. Utility Model Content

[0005] A hot asphalt spraying device for curbstones comprises a frame, one side of the frame is provided with a spray hood fixed thereto, the frame is also provided with an oil pipe, the output end of the oil pipe is located in the spray hood, and the input end of the oil pipe is connected to a hose.

[0006] As a preferred embodiment of the hot asphalt spraying device for curbstones in the utility model, the frame includes a transverse frame and a longitudinal frame. The bottom of the transverse frame is connected to the directional wheel through a lifting screw rod. The longitudinal frame is arranged in the movement direction of the transverse frame, and its bottom is fixedly connected to one side of the top of the transverse frame.

[0007] As a preferred embodiment of the hot asphalt spraying device for curbstones in the utility model, an auxiliary component is provided on the transverse frame, which includes a sleeve, which is fixedly connected to the transverse frame and arranged perpendicular to the movement direction of the transverse frame. A through hole is provided on one side of the sleeve, and a connecting block fixedly connected to the sleeve is provided at the through hole. A threaded hole is provided at a position corresponding to the through hole, and a screw is provided in the threaded hole to be screwed and connected thereto; an insertion rod is sleeved in the sleeve, and a universal wheel is provided at one end of the insertion rod.

[0008] As a preferred embodiment of the hot asphalt spraying device for curbstones of the utility model, the longitudinal frame is provided with a handle.

[0009] As a preferred embodiment of the hot asphalt spraying device for curbstones in the utility model, the spray hood includes a hood body, one end of the hood body is fixedly connected to the transverse frame, and the other end of the hood body is provided with a felt detachably connected thereto.

[0010] As a preferred embodiment of the hot asphalt spraying device for curbstones of the utility model, the oil pipe is provided with a spray switch.

[0011] Beneficial effects of the utility model:

[0012] The utility model connects the oil pipe with the spray pipe, and uses a frame to fix the oil pipe and the spraying position thereof. Construction workers can carry out spraying operations by pushing the frame along the curb, thereby reducing the technical requirements for hot asphalt spraying operations. At the same time, a spray hood arranged above the oil pipe limits the hot asphalt splashed during the spraying process within the spray hood, thereby effectively avoiding the splashing of hot asphalt.

[0030] Example

[0031] This embodiment provides a hot asphalt spraying device for curbstones, such as Figure 1 As shown, the frame 1 includes a frame 1, a spray hood 2 fixedly connected to the frame 1 near the curb is provided, and an oil pipe 3 is also provided on the frame 1, the output end of the oil pipe 3 is located in the spray hood 2, and the input end is connected to the hose. When in use, the frame 1 moves along the curb, and hot asphalt is sprayed on the curb through the oil pipe 3, and the spray hood 2 intercepts the hot asphalt splashed during the spraying process so that it falls within the range of the spray hood 2.

[0032] like Figure 2 to Figure 3 As shown, the frame 1 includes a transverse frame 11 and a longitudinal frame 12. The bottom of the transverse frame 11 is connected to the directional wheel 4 through a lifting screw. The lifting screw is used to adjust the distance between the transverse frame 11 and the ground to adapt to different spraying heights. The longitudinal frame 12 is arranged in the movement direction of the transverse frame 11, and its bottom is fixed to one side of the top of the transverse frame 11.

[0033] The transverse frame 11 is provided with an auxiliary component 5, at least one of which is provided, and includes a sleeve 51, which is fixedly connected to the transverse frame 11 and arranged perpendicular to the movement direction of the transverse frame 11, and a through hole is provided on one side of the sleeve 51, and a connecting block 52 fixedly connected to the sleeve 51 is provided at the through hole, and a threaded hole is provided at a position corresponding to the through hole of the connecting block 52, and a screw 53 is provided in the threaded hole to be screwed and connected thereto; an insert rod 54 is sleeved in the sleeve 51, and a universal wheel 55 is provided at one end of the insert rod 54. The fixed position of the insert rod 54 can be adjusted by adjusting the screw 53, so as to adjust the spacing between the side of the positioning device and the curb.

[0035] In this embodiment, the spray hood 2 includes a hood body 21, one end of the hood body 21 is fixedly connected to the transverse frame 11, and the other end thereof is provided with a felt 22 detachably connected thereto. By adjusting the felt 22, the positioning device can be adapted to spraying at different intervals. At the same time, most of the hot asphalt splashed during the spraying process falls into the felt 22. When cleaning is required, the felt 22 can be directly replaced, which is convenient and quick.

[0036] The oil pipe 3 is L-shaped as a whole and is made of stainless steel, ensuring that the equipment has excellent corrosion resistance and durability and can maintain a stable working state for a long time. Its output end is connected to the transverse frame 11 by a wire tie, and its input end is provided with a nozzle, and the output end is connected to the longitudinal frame 12 by a wire tie. The oil pipe 3 is also provided with a spray switch, which is used to control parameters such as spraying flow, pressure and speed to achieve a more precise spraying effect.

[0037] When in use, the frame 1 is used to support the entire device, the directional wheels 4 and the universal wheels 55 are used to realize the movement and positioning of the device, the lifting screw can flexibly adjust the spraying height, the spray hood 2 and the nozzle are used to realize the precise spraying of hot asphalt and prevent the occurrence of splashing, thereby improving the construction quality and efficiency.

[0038] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
