Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of pitch pouring joint device, concretely relates to a portable concrete pavement contraction joint pitch pouring joint device. BACKGROUND

[0002] In concrete pavement maintenance, pitch pouring joint construction of contraction joint is a key process, which is directly related to the service life and driving safety of road. However, the traditional construction method, especially the method of relying on old leak pot to burn pitch, has gradually shown its limitations. The old leak pot not only has complex operation and low efficiency, but also has obvious technical defects in the process of pitch pouring.

[0003] The old leak pot is difficult to accurately control the flow and temperature of pitch, which directly leads to different depths of pitch when pouring into the contraction joint of pavement, and it is difficult to achieve the expected filling effect. Some areas may have gaps due to insufficient pitch, and these gaps may become channels for water penetration in the future, accelerating the damage of the pavement. INVENTION CONTENTS

[0026] Example 1

[0027] like Figs. 1-2 As shown, this embodiment provides a portable concrete pavement shrinkage joint asphalt sealing device, comprising a support walking mechanism 1, an asphalt container 2, an output pipe 3, an asphalt guide 4, and a cleaning component 5.

[0028] The support walking mechanism 1 comprises a support frame 11 and walking members 12 installed on both sides of the support frame 11. The walking members 12 are rollers.

[0029] The asphalt container 2 is installed on the support member. The asphalt container 2 has a sandwich space. A heating member is arranged in the sandwich space. The heating member adopts heating elements such as electric heating wires, electric heating plates, and electric heating tubes. Through heating treatment, the asphalt is changed into a liquid state, thereby significantly improving its fluidity; this enables the asphalt to penetrate deeper into the cracks, ensuring the compactness and integrity of the crack filling.

[0030] An output pipe 3 is arranged at the bottom end of the asphalt container 2, and the output pipe 3 is in communication with the inside of the asphalt container 2. The output pipe 3 is used to output the heated asphalt.

[0031] An asphalt guide 4 is installed on the support frame 11 below the output pipe 3. The asphalt guide 4 is arranged to guide the asphalt flowing out of the output pipe 3 to flow into the shrinkage joint to be treated.

[0032] The asphalt guide 4 can accurately guide the asphalt flowing out of the output pipe 3 to flow into the shrinkage joint to be treated; this design ensures that the asphalt can be accurately delivered to the location that needs to be repaired, avoiding waste and misoperation of the asphalt.

[0033] The design of the asphalt guide 4 enables the asphalt to flow into the shrinkage joint along a predetermined path, avoiding deviation or splashing of the asphalt during the flow process, enhancing the accuracy of construction, and ensuring the repair quality.

[0034] A cleaning member 5 is arranged on one side of the asphalt guide 4 and close to the inclination of the asphalt guide 4. The cleaning member 5 is arranged to clean the shrinkage joint. When the support frame 11 is pushed to walk, the cleaning frame is arranged in front along the walking direction, and the cleaning member 5 can clean the debris and residues in the shrinkage joint in advance; this helps to prevent the blockage of the shrinkage joint and ensures that the asphalt can flow into and fill the cracks smoothly.

[0035] Further, the inner wall of the bottom of the asphalt guide 4 is provided with a guide surface. The asphalt flows on the guide surface. The width of the guide surface gradually decreases along the flow direction of the asphalt.

[0036] The gradually narrowing guide surface along the flow direction of the asphalt can guide the asphalt to flow more smoothly into the shrinkage joint to be treated, ensuring that the asphalt can flow along a predetermined path, improving the accuracy and efficiency of construction.

[0037] The design of the guide surface enables the asphalt to flow accurately into the shrinkage joint, avoiding splashing and waste of the asphalt during the flow process; this not only reduces the construction cost, but also helps to protect the construction environment and reduce the impact on the environment.

[0038] Further, the asphalt container 2 further comprises a stirring element 6 and a drive motor 7. The stirring element 6 is installed inside the asphalt container 2. The output end of the drive motor 7 is connected to the stirring element 6. The drive motor 7 drives the stirring element 6 to rotate. The rotating stirring element 6 stirs the asphalt during the filling process, ensuring that the asphalt remains uniform in the asphalt container 2; this helps to avoid problems such as asphalt stratification, sedimentation or uneven solidification, thereby improving the use effect of the asphalt.

[0039] Further, the asphalt container 2 is provided with a heat preservation layer on the outer wall. The heat preservation layer effectively controls the temperature in the asphalt container 2, preventing heat loss; this helps to keep the asphalt within the appropriate working temperature range, improving construction efficiency and quality.

[0040] Further, the guide surface is inclined at a predetermined angle, and the predetermined angle is in the range of 7°~11°. The inclined guide surface can guide the asphalt to flow along the inclined surface, reducing the flow resistance; this design helps to speed up the flow speed of the asphalt, improving the filling efficiency.

[0041] The inclined guide surface can reduce the accumulation and blockage of asphalt during the flow process. This helps to ensure that the asphalt can flow smoothly into the cracks, improving the repair quality.

[0042] Further, one side of the support frame 11 is provided with a pull rod 9, which facilitates the operator to push the support frame 11.

[0043] Further, the valve switch 8 is provided for controlling the flow of asphalt. The provision of the valve switch 8 allows the operator to adjust the flow of asphalt as needed; this is particularly important when carrying out road repair or crack filling work, as different work scenarios may require different amounts of asphalt. Through the valve switch 8, the flow of asphalt can be easily adjusted, ensuring the accuracy and efficiency of the work.
