Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, and specifically, to a highway construction roller with a line-drawing positioning function. Background Art

[0002] A roller, also known as a soil compactor, is a road construction device. Rollers belong to the category of road equipment in construction machinery and are widely used for filling and compaction operations in large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can roll sandy, semi-viscous, and viscous soils, subgrade stabilized soils, and asphalt concrete pavement layers. With the gravity of the machine itself, rollers are suitable for various compaction operations, causing permanent deformation and compaction of the compacted layer.

[0003] When the existing highway construction rollers are working, they need to rely on the naked eye to observe the positions where rolling should be carried out, and then drive the rollers to apply pressure to the road surface. However, since only the ground is observed with the naked eye and there is no line as a reference, this often causes the rollers to deviate. The deviation of the rollers will lead to uneven compaction of the road surface. Some places are over-compacted, while some places are under-compacted. This will result in inconsistent strength and stability of the road surface and is prone to quality problems such as cracks and potholes. In view of this, we propose a highway construction roller with a line-drawing positioning function. Content of the Utility Model

[0004] The purpose of the present utility model is to solve the above-mentioned drawbacks and provide a highway construction roller with a line-drawing positioning function;

[0005] To achieve the above purpose, the present utility model provides a highway construction roller with a line-drawing positioning function, including a main body bracket. Two support columns are fixedly connected to the surface of the main body bracket. A connecting pipe for transmitting pigment is provided inside the support column. The bottom of the connecting pipe is threadedly connected to an elastic telescopic pipe. The elastic telescopic pipe is located at the bottom of a protective bracket. One end of the elastic telescopic pipe away from the connecting pipe is provided with a nozzle for spraying the pigment onto the ground. Due to the setting of the elastic telescopic pipe, the distance between the nozzle and the ground can be adjusted, and the pigment inside the connecting pipe is transmitted to the nozzle through the elastic telescopic pipe and sprayed on the surface by the nozzle, thereby determining the working position and boundary of the roller.

[0006] As a further improvement of this technical solution, a water pump for transmitting pigment is provided at the end of the connecting pipe. A storage tank for carrying the pigment is provided on the surface of the water pump. Due to the setting of the water pump, the pigment inside the storage tank can enter the connecting pipe through the water pump and then be transmitted to the nozzle.

[0007] As a further improvement of this technical solution, a through hole is opened at the top of the storage tank, and a feed inlet for adding pigments is provided on the inner wall of the through hole. Since the feed inlet is opened, pigments can enter the interior of the storage tank through the feed inlet.

[0008] As a further improvement of this technical solution, a protective bracket for supporting the storage tank is provided at the top of the main body bracket, and a water pump is fixedly connected to the bottom of the inner cavity of the protective bracket.

[0009] As a further improvement of this technical solution, a rolling roller for processing the ground is provided in the inner cavity of the main body bracket, and a plurality of bumps are provided on the surface of the rolling roller to improve the uniformity and density of compaction.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] In this road construction roller with a line-drawing positioning function, the working position and boundary are determined by spraying pigments on the ground through the nozzle, avoiding the roller from deviating due to no line reference for visual observation, ensuring uniform compaction of the road surface, improving the road surface quality, and the elastic telescopic tube can adjust the distance between the nozzle and the ground, and can be flexibly adjusted according to the undulation and specific conditions of the road surface, increasing the practicability and adaptability of the device, ensuring uniform compaction of the road surface, making the road surface strength and stability consistent, reducing quality problems such as cracks and potholes, and extending the service life of the road.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment

[0022] Please refer to Figures 1 - 4 As shown, this embodiment provides a road construction roller with a line-drawing positioning function, including a main body bracket 1. When the existing road construction roller is working, it needs to rely on the naked eye to observe the position where rolling should be carried out, and then drive the roller to apply pressure to the road surface. However, since only the ground is observed with the naked eye and there is no line as a reference, this often causes the roller to deviate. The deviation of the roller will result in uneven compaction of the road surface, with some places being over-compacted and some places being under-compacted. This will make the strength and stability of the road surface inconsistent and prone to quality problems such as cracks and potholes. In view of this, we propose a road construction roller with a line-drawing positioning function. Therefore, two support columns 111 are fixedly connected to the surface of the main body bracket 1. A connecting pipe 23 for transmitting pigment is provided inside the support column 111. The bottom of the connecting pipe 23 is threadedly connected to an elastic telescopic pipe 24. The elastic telescopic pipe 24 is located at the bottom of the protection bracket 11. One end of the elastic telescopic pipe 24 away from the connecting pipe 23 is provided with a nozzle 240 for spraying the pigment onto the ground. Since the elastic telescopic pipe 24 is provided, the distance between the nozzle 240 and the ground can be adjusted, and the pigment inside the connecting pipe 23 is transmitted to the nozzle 240 through the elastic telescopic pipe 24 and sprayed on the surface by the nozzle 240, thereby determining the working position and boundary of the roller. By pulling the nozzle 240 downward, the elastic telescopic pipe 24 can be extended, and the height of the nozzle 240 from the ground can be adjusted through the extension of the elastic telescopic pipe 24, so that it can be adjusted according to the road surface conditions, increasing the practicality of the device. Since the pigment inside the connecting pipe 23 can be transmitted to the nozzle 240 through the elastic telescopic pipe 24 and then sprayed on the ground by the nozzle 240, the working position and boundary of the roller are determined.

[0023] The improvement in this embodiment lies in:

[0024] Considering that when existing road construction rollers are working, they need to rely on the naked eye to observe the positions where rolling should be carried out, and then drive the roller to apply pressure to the road surface. However, since only the ground is observed with the naked eye and there is no line as a reference, this often causes the roller to deviate from the straight path. The deviation of the roller will lead to uneven compaction of the road surface, with some places being over-compacted and some places being under-compacted. This will make the strength and stability of the road surface inconsistent and prone to quality problems such as cracks and potholes. In view of this, we propose a road construction roller with a line-drawing positioning function. Therefore, the working position and boundary are determined by spraying paint on the ground through the nozzle 240, which avoids the roller from deviating due to the lack of a line reference when observing with the naked eye, ensures uniform compaction of the road surface, improves the road surface quality, and the elastic telescopic tube 24 can adjust the distance between the nozzle 240 and the ground, and can be flexibly adjusted according to the undulation and specific conditions of the road surface, increasing the practicability and adaptability of the device, ensuring uniform compaction of the road surface, making the strength and stability of the road surface consistent, reducing quality problems such as cracks and potholes, and extending the service life of the road.

[0025] In order to enable the connecting pipe 23 to transfer the paint into the nozzle 240, therefore, a water pump 22 for transferring the paint is provided at the end of the connecting pipe 23, and a storage tank 2 for carrying the paint is provided on the surface of the water pump 22. Due to the setting of the water pump 22, the paint in the storage tank 2 can enter the connecting pipe 23 through the water pump 22 and then be transferred into the nozzle 240. Through the operation of the water pump 22, the paint in the storage tank 2 can be transferred into the connecting pipe 23 through the water pump 22.

[0026] In order to facilitate the addition of paint to the storage tank 2, therefore, a through hole is opened at the top of the storage tank 2, and a feed port 21 for adding paint is provided on the inner wall of the through hole. Due to the opening of the feed port 21, the paint can enter the storage tank 2 through the feed port 21. By pouring the paint at the opening of the feed port 21, the paint will enter the storage tank 2 through the feed port 21 at this time.

[0027] In order to enable the storage tank 2 to carry the paint, the storage tank 2 needs to be supported. Therefore, a protective bracket 11 for supporting the storage tank 2 is provided at the top of the main body bracket 1, and the water pump 22 is fixedly connected to the bottom of the inner cavity of the protective bracket 11. By providing the protective bracket 11, the storage tank 2 and the water pump 22 can be supported, enabling the storage tank 2 to carry the paint.

[0028] In order to enable the device to apply pressure to the road surface and level the ground, therefore, a rolling roller 110 for processing the ground is provided in the inner cavity of the main body bracket 1, and a plurality of bumps are provided on the surface of the rolling roller 110 to improve the uniformity and density of compaction. By installing the main body bracket 1 on the roller, the rolling roller 110 can move on the ground that needs to be flattened through the movement of the roller.

[0029] When the road construction roller with a line-drawing positioning function of the present utility model is in specific use, by installing the device on the roller, pulling the nozzle 240 downward can extend the elastic telescopic tube 24. The height between the nozzle 240 and the ground can be adjusted through the extension of the elastic telescopic tube 24. At this time, pour the pigment into the opening of the feed port 21. Then the pigment will enter the interior of the storage tank 2 through the feed port 21. Driving the water pump 22 to work can make the pigment in the storage tank 2 be transmitted through the water pump 22 into the interior of the connecting pipe 23. Since the pigment in the connecting pipe 23 can be transmitted to the nozzle 240 via the elastic telescopic tube 24 and then sprayed on the ground by the nozzle 240, the working position and boundary of the roller can be determined. By compressing the elastic telescopic tube 24 to move the nozzle 240 upward and increasing the distance from the ground, and driving the roller to move the device downward to make the rolling roller 110 contact the ground. At this time, the movement of the roller can make the rolling roller 110 move on the ground that needs to be flattened. When the roller moves, it can move according to the trajectory of the pigment sprayed by the nozzle 240.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only the preferred examples of the present utility model and are not used to limit the present utility model.
