Description

Technical Field

[0001] This utility model belongs to the field of road construction technology, specifically relating to a curbstone emulsified asphalt spraying device. Background Technology

[0002] In modern municipal engineering construction, curb stones are an important component of road facilities, and their construction quality plays a crucial role in the overall aesthetics and practicality of roads. Emulsified asphalt is widely used in curb stone construction, as it effectively enhances the adhesion between the curb stone and the road surface, improves waterproofing and anti-slip performance, and extends the service life of the curb stone.

[0003] Patent application CN202323559109.2 discloses a curbstone emulsified asphalt spraying device. A fixed frame 15 is fixedly installed above a base 1, located outside an asphalt tank 2. The fixed frame 15 and a movable plate 16 provide an assembly position for the spray head 3. The movable plate 16 is fitted above the fixed frame 15, and the spray head 3 is fixedly mounted on the movable plate 16. The height of the spray head 3 outside the base 1 can be adjusted by moving the movable plate 16. An adjusting screw 20 is movably mounted on the fixed frame 15 via a bearing. The adjusting screw 20 is threadedly connected to the movable plate 16. Guide rods symmetrically distributed on both sides of the adjusting screw 20 are fixedly installed on the fixed frame 15. When the adjusting screw 20 is rotated, the adjusting screw 20 pushes the movable plate 16 along the guide rods through its outer thread. The guide rods and the movable plate 16 are slidably connected, thus adjusting the height of the spray head 3 to meet the spraying needs of curbstones of different heights.

[0004] However, the aforementioned emulsified asphalt spraying operation for curb stones has many drawbacks. (Refer to the appendix of the aforementioned document.) Figure 1 , Figure 2 , Figure 3 and Figure 4 As can be seen, the movable plate 16 is movably inserted into the fixed part 15. When adjusting the height, the height of the spray head 3 changes. The direction of the spray head 3 is horizontal, flush with the road surface. The back of the curbstone cannot be effectively sprayed. Furthermore, because the movable plate 16 is a movable structure, the aforementioned document does not mention a corresponding precise adjustment structure, making it difficult to ensure that the spraying height is consistent each time. Therefore, it is also impossible to guarantee the consistent thickness and uniformity of the paint sprayed on the curbstone surface, easily resulting in areas that are too thick or too thin, leading to inconsistent curbstone quality. Moreover, the spraying position cannot be precisely controlled, often resulting in asphalt splattering into surrounding areas, wasting materials, polluting the environment, and requiring a large amount of subsequent cleanup work.

[0026] Example

[0027] Reference Figure 1-4 This embodiment of the present invention provides a curbstone emulsified asphalt spraying device, comprising:

[0028] The storage assembly 100 includes a bracket 101, a material bucket 102 fixedly connected to the upper end of the bracket 101, and a feeding pipe 103 encapsulated on the top of the material bucket 102. The feeding pipe 103 communicates with the inside of the material bucket 102, and a pipe cap 104 is installed on the top of the feeding pipe 103.

[0029] The spraying assembly 200 includes a material pump 201 fixedly connected to the middle position of the bracket 101, a housing 202 bolted to the end of the bracket 101, a sleeve 203 welded to the side wall of the housing 202, a support rod 204 movably inserted into the middle of the sleeve 203, a cover plate 205 fixedly connected to the end of the support rod 204, and a spray head 206 fixedly connected to the side wall of the cover plate 205. The material pump 201 inlet is connected to the material tank 102 bottom outlet through a pipe, and the material pump 201 outlet is connected to the spray head 206 through a pipe.

[0030] The support frame 101 serves as the basic support structure for the entire material storage assembly. The material hopper 102, fixedly connected to the upper end of the support frame 101, is the container for storing emulsified asphalt. A feed pipe 103 is encapsulated on the top of the material hopper 102, used to add emulsified asphalt into the hopper 102. A pipe cap 104 is installed on top of the feed pipe 103, serving a sealing and dustproof function. The cap should be closed promptly after feeding to prevent impurities from entering the hopper 102 and affecting the quality of the emulsified asphalt. The pump 201 is fixedly connected to the middle of the support frame 101. It is the power device that transports the emulsified asphalt from the material hopper 102 to the nozzle. The inlet is connected to the outlet at the bottom of the material hopper 102 via a pipe, and the outlet is connected to the nozzle 206 via a pipe, forming a complete material conveying channel. The sleeve 203 is welded to the side wall of the housing 202, providing a channel for the movement of the support rod 204. The inner diameter of the sleeve is matched with the outer diameter of the support rod 204, allowing the support rod 204 to slide flexibly within the sleeve 203. The cover plate 205 is fixedly connected to the end of the support rod 204, serving to protect the nozzle 206 and guide the spraying direction. It prevents emulsified asphalt from splashing during spraying and ensures that the delivered emulsified asphalt is evenly sprayed onto the curbstone surface. The type and specifications of the nozzle 206 are selected according to actual spraying requirements to ensure that the spraying effect meets the requirements.

[0031] Specifically, the spraying assembly 200 also includes a lifting cylinder 207 fixedly connected to the inner wall of the housing 202, with the end of the lifting cylinder 207 fixedly connected to the upper side wall of the cover plate 205.

[0032] The function of the lifting cylinder 207 is to drive the cover plate 205 and the spray head 206 to move vertically. By controlling the extension and retraction of the main shaft, the distance between the spray head 206 and the curb stone surface can be adjusted, thereby achieving the adjustment of different spray thicknesses and effects.

[0033] Furthermore, the spraying assembly 200 also includes an extension plate 208 slidably mounted on the side wall of the cover plate 205, and a translation cylinder 209 mounted on the end of the extension plate 208. The end of the translation cylinder 209 is fixedly connected to the side wall of the cover plate 205, and the spray nozzle 206 is adapted to be mounted on the side wall of the extension plate 208.

[0034] The extension plate 208 is used to further expand the spraying range of the nozzle. By sliding on the side wall of the cover plate 205, the coverage range of the nozzle 206 in the horizontal direction can be changed, thereby meeting the spraying needs of curb stones of different widths.

[0035] Furthermore, the storage assembly 100 also includes a motor 105 fixedly connected to the outer wall of the material barrel 102, and a stirring rod 106 rotatably installed inside the material barrel 102. The output end of the motor 105 is connected to the end of the stirring rod 106 via a coupling. The end of the stirring rod 106 does not contact the inner wall of the material barrel 102, and the stirring rod 106 runs below the feeding pipe 103.

[0036] The motor 105 is fixedly connected to the outer wall of the material bucket 102. It provides power to the stirring rod 106 and can stably drive the stirring rod 106 to rotate, so as to meet the requirements of emulsified asphalt mixing, prevent asphalt from settling and stratifying, and ensure the uniformity of the material.

[0037] It should be noted that the storage assembly 100 also includes a positioning seat 107 fixedly connected to the upper side wall of the bracket 101, and an electric heating tube 108 installed on the inner wall of the positioning seat 107. The positioning seat 107 is snapped onto the lower outer side wall of the material bucket 102, the electric heating tube 108 is located on the outer side wall of the material bucket 102, the positioning seat 107 has a cavity structure inside, and a liquid supply pipe is installed on the side wall of the positioning seat 107.

[0038] The positioning seat 107 is used to position and fix the material bucket 102, and also provides an installation position for the heating element 108. Its side wall is equipped with a liquid supply pipe, which can be used to introduce heating medium or coolant to regulate the temperature of the material inside the material bucket 102. The main function of the heating element 108 is to heat the emulsified asphalt inside the material bucket 102 to maintain the asphalt's fluidity. By controlling the heating power of the heating element 108, the temperature of the emulsified asphalt can be maintained within a suitable range, ensuring the smooth progress of the spraying operation.

[0039] When using emulsified asphalt for kerbstone spraying, first open the cap 104 at the top of the supply pipe 103 and add the emulsified asphalt into the bucket 102 through the supply pipe. After adding, close the cap. Start the motor 105, which drives the stirring rod 106 to rotate, stirring the emulsified asphalt in the bucket 102 to keep the material uniform. Simultaneously, if necessary, activate the heating element 108 to heat the emulsified asphalt in the bucket 102. The temperature can be assisted by the liquid supply pipe in the positioning seat 107 to ensure good asphalt fluidity. After preparation, start the material pump 201, which draws the emulsified asphalt from the bottom outlet of the bucket 102 and delivers it to the nozzle 206 through the pipe. During spraying, the movement of the lifting cylinder 207 and the translation cylinder 209 can be controlled according to the height and width of the kerbstone. The lifting cylinder 207 drives the cover plate 205 and the nozzle 206 to move vertically up and down, adjusting the distance between the nozzle and the curbstone surface; the translation cylinder 209 drives the extension plate 208 to slide on the side wall of the cover plate 205, changing the position of the nozzle in the horizontal direction, thereby achieving precise spraying of the curbstone at different positions and angles.

[0040] In summary, the mixing rod and heating device in the material storage assembly effectively prevent emulsified asphalt from settling and separating, maintaining the uniformity and flowability of the material and ensuring the stability of the spraying quality. Continuous mixing by the mixing rod ensures thorough mixing of the various components in the asphalt, preventing uneven spraying caused by settling. The heating device can control the temperature within a suitable range based on the ambient temperature and the characteristics of the asphalt, ensuring smooth flow of the asphalt during spraying and preventing it from becoming viscous and clogging pipes or nozzles due to excessively low temperatures.

[0041] The lifting and translation cylinders in the spraying assembly allow for vertical and horizontal nozzle position adjustment, accommodating curb stones of different sizes and shapes, thus improving the device's versatility and applicability. Whether the curb stone is tall or wide, adjusting the nozzle position ensures accurate spraying of emulsified asphalt to the desired area, guaranteeing satisfactory spraying results. The shroud design effectively prevents emulsified asphalt splattering, reducing material waste and environmental pollution. By collecting and guiding splattered asphalt back to the work area, material utilization is improved, and production costs are reduced.
