Description

Technical Field

[0001] The utility model belongs to the technical field of highway construction equipment and relates to a water spraying device for a road roller. Background Art

[0002] A road roller, also known as a soil compactor, is a type of road construction equipment, available in two types: steel-wheeled and tire-type. Specified as road equipment within the construction machinery category, road rollers are widely used for fill and compaction operations on large-scale projects such as highways, railways, airport runways, dams, and stadiums. They can compact sandy, semi-cohesive, and cohesive soils, stabilized roadbed soils, and asphalt concrete pavement layers. Using the force of the machine itself, rollers are suitable for various compaction operations, achieving permanent deformation and densification of the compacted layer.

[0003] When a single steel wheel vibratory roller is rolling asphalt pavement, it is necessary to spray water on the surface of the steel wheel to prevent the asphalt mixture from sticking to the steel wheel and damaging the smoothness of the road surface. In addition, the asphalt mixture adhering to the steel wheel will rub and collide with the scraper of the roller and damage the scraper. Therefore, during use, it is necessary to spray water on the surface of the steel wheel of the roller to cool it down to prevent adhesion. Currently, a water spray pipe is installed above the steel wheel of the roller to spray water on the surface of the steel wheel for cooling, but this method is close to water cooling and the cooling effect is not good.

[0018] The utility model is described in detail below with reference to the accompanying drawings:

[0019] like Figure 1 and 2As shown, a water spraying device for a road roller comprises a road roller body 1, a steel wheel 2 is provided on the road roller body 1, and the road roller body 1 adopts the existing conventional single-steel wheel road roller body, and a horizontally arranged water spraying pipe 3 is provided on one side of the steel wheel 2 along the axial direction of the steel wheel 2. The water spraying pipe 3 is used to spray water onto the surface of the steel wheel 2, and the water spraying pipe 3 is a stainless steel pipe with blocked ends. Specifically, a connecting frame 4 is provided on the road roller body 1, and the water spraying pipe 3 is fixed on the connecting frame 4. A water supply pipe 5 is connected to the middle part of the water spraying pipe 3, and the water supply pipe 5 is connected to a water tank 6 for storing cooling water. The water tank 6 is fixed on the road roller body 1, and a water pump 7 and a water supply valve 8 are provided on the water supply pipe 5. The cooling water in the water tank 6 can be input into the water spraying pipe 3 through the water supply pipe 5 through the water pump 7. A plurality of water outlet pipes 9 are connected to the water spraying pipe 3 along the length direction of the water spraying pipe 3. Cooling water can be sprayed onto the surface of the steel wheel 2 through the water outlet pipe 9. A horizontally arranged jet pipe 10 is provided on one side of the water spray pipe 3 along the axial direction of the steel wheel 2. The jet pipe 10 is a stainless steel pipe with both ends blocked. The jet pipe 10 is fixedly mounted on the connecting frame 4. A plurality of air outlet pipes 11 corresponding to the water outlet pipe 9 are provided on the jet pipe 10. The air outlet pipe 11 has a flat rectangular structure. The flat rectangular structure can increase the blowing area. An angle of 15-30 degrees is formed between the air outlet pipe 11 and the water outlet pipe 9. The gas ejected from the air outlet pipe 11 can increase the speed at which the cooling water is ejected from the water outlet pipe 9, and at the same time, the surface of the steel wheel 2 can be air-cooled, thereby effectively improving the cooling effect. At the same time, some impurities adhering to the steel wheel 2 can also be removed. The jet pipe 10 is connected to the air supply pipe 12, and the air supply pipe 12 is connected to the air compressor 13. The air compressor 13 is fixed to the roller body 1.

[0020] In order to timely understand the water level in the water tank 6, a water level sensor 14 is provided on the water tank 6. The water level in the water tank 6 can be detected by the water level sensor 14 to prevent the roller from continuing to run when there is no water in the water tank 6, causing asphalt to stick to the steel wheel 2 and affecting the road rolling effect.

[0021] The usage of this utility model is as follows:

[0022] When the roller body 1 is rolling the road, the water pump 7 and the water valve 8 are turned on, and the air compressor 13 is turned on at the same time. The cooling water in the water tank 6 is input into the water spray pipe 3 through the water pipe 5 under the action of the water pump 7, and finally sprayed out through the water outlet pipe 9. At the same time, the air compressor 13 transports gas to the jet pipe 10 through the air pipe 12, and finally sprays the gas through the outlet pipe 11. The sprayed gas can increase the speed of the cooling water sprayed from the corresponding water outlet pipe 9. The accelerated cooling water is sprayed onto the surface of the steel wheel 2 to cool the steel wheel. Since the cooling water spray speed is fast, the cooling effect can be improved. The gas sprayed through the outlet pipe 11 can also cool the surface of the steel wheel 2, further improving the cooling effect, effectively reducing the temperature of the steel wheel 2, and preventing asphalt from sticking. At the same time, it can also remove some impurities adhering to the steel wheel 2, thereby improving the rolling effect.
