Abstract
Description
Technical Field
[0001] This utility model relates to the field of road construction technology, and in particular to a quick-installation paver heating device bracket. Background Technology
[0002] In modern road construction, asphalt pavement is widely used due to its advantages such as smoothness, comfort, and short construction period. However, due to the complexity of the construction process, such as phased construction and limitations on equipment operating range, cold joints inevitably occur in asphalt pavement. These are joints formed between newly laid asphalt mixture and previously laid sections that have cooled and hardened. The existence of cold joints directly affects the overall performance and service life of the pavement. Therefore, efficient and reliable cold joint treatment technology has become one of the key aspects of asphalt pavement construction.
[0003] Currently, common cold joint treatment technologies for asphalt pavements include traditional manual heating and some simple mechanically assisted heating. Manual heating mainly uses tools such as flame guns and infrared heating plates to heat the cold joint area manually, softening the old asphalt before laying the new material. Mechanically assisted heating typically involves installing heating devices independently on the paver, performing a secondary heating treatment on the cold joint after the paver has completed paving. Both methods are based on the principle of heat conduction, using an external heat source to increase the temperature at the cold joint and promote the bonding between the old and new asphalt.
[0004] However, traditional cold joint treatment methods have significant drawbacks. Manual heating is greatly affected by human operation, and the heating temperature and time are difficult to control precisely. This can easily lead to poor adhesion between the old and new asphalt materials at the cold joint due to large temperature differences. Under vehicle loads and environmental factors, the joint area is prone to cracking and water seepage, which seriously affects the smoothness and durability of the pavement and significantly shortens its service life. Mechanically assisted heating, on the other hand, is difficult to achieve synchronous operation because the equipment is separate from the paver, resulting in low construction efficiency and high equipment costs, leading to poor economic benefits and hindering large-scale promotion and application.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figures 1-3 The present invention provides an embodiment of a quick-install paver heating device bracket, including a mounting plate 1, a limit component provided on the outer wall of the mounting plate 1, and a heating component provided on the outer wall of the mounting plate 1;
[0027] The heating assembly includes a heating nozzle 11, which sprays high-temperature gas onto the asphalt cold joint to soften the old asphalt and promote the fusion of the new and old asphalt. The heating nozzle 11 is located on the outer wall of the mounting plate 1. A gas tank 6 is located above the mounting plate 1, and the gas is transported from the gas tank 6 to the high-frequency heating coil 16. A fuel delivery pipe 9 is fixedly connected to the output end of the gas tank 6. A switch valve 8 is located on the outer wall of the gas tank 6. A high-frequency heating coil 16 is fixedly connected to one end of the fuel delivery pipe 9. A support block 4 is fixedly connected to the outer wall of the mounting plate 1. A heat-conducting cylinder 10 is fixedly connected to the outer wall of the support block 4. Utilizing the high thermal conductivity of aluminum, the heat of the heating wire 15 is quickly transferred to the internal high-frequency heating coil 16, enhancing the gas heating efficiency. A heating wire 15 is installed in the interlayer of the heat-conducting cylinder 10. A fuel delivery pipe 14 is fixedly connected to one end of the high-frequency heating coil 16. A regulating valve 13 is located on the upper side of the outer wall of the fuel delivery pipe 14. A pressure gauge 12 is located on the lower side of the outer wall of the fuel delivery pipe 14.
[0028] Specifically, the switch valve 8 on the gas cylinder 6 is opened, and the gas enters the high-frequency heating coil 16 through the fuel delivery pipe 1 9. The high-frequency heating coil 16 is located inside the aluminum heat-conducting cylinder 10. Due to the good thermal conductivity of aluminum, the heat generated by the heating wire 15 is quickly transferred to the heat-conducting cylinder 10, thereby heating the gas inside the high-frequency heating coil 16. The heated gas then flows through the fuel delivery pipe 2 14, and the flow rate is controlled by the regulating valve 13. The pressure gauge 12 displays the pressure in real time, and finally the asphalt cold joint is heated through the heating nozzle 11.
[0029] Reference Figures 1-5 The limiting component includes a semi-circular plate 7, which fits against the outer wall of the gas tank 6. The spring force of the spring 18 provides lateral clamping force to prevent the gas tank 6 from shaking. The semi-circular plate 7 is set on the outer wall of the mounting plate 1. A limiting platform 5 is fixedly connected to the upper surface of the mounting plate 1 to initially position the gas tank 6 and limit its lateral movement. A sliding column 17 is fixedly connected to the inner wall of the mounting plate 1. A spring 18 is sleeved on the outer wall of the sliding column 17. A connecting plate 19 is slidably connected to the outer wall of the sliding column 17. Connecting blocks 2 are provided on both sides of the outer wall of the mounting plate 1. Fixing bolts 3 are threadedly connected to the inner wall of the connecting blocks 2. The mounting plate 1 is used to install on the rear of the paver. At the plate, fixing bolt 3 is used to fix the mounting plate 1. One end of spring 18 is fixedly connected to the inner wall of mounting plate 1. The other end of sliding column 17 is fixedly connected to the outer wall of connecting plate 19. The outer wall of connecting plate 19 is fixedly connected to the inner wall of semi-arc plate 7. The outer wall of gas tank 6 is slidably connected to the inner wall of limiting platform 5. One end of fuel delivery pipe 14 is fixedly connected to the other end of heating nozzle 11. Fuel delivery pipe 14 is used to deliver fuel. High frequency heating coil 16 is set on the inner wall of heat conduction cylinder 10. Heat conduction cylinder 10 is made of aluminum. The outer wall of gas tank 6 is slidably connected to the inner wall of semi-arc plate 7. Semi-arc plate 7 is used to limit the gas tank 6.
[0030] Specifically, the mounting plate 1 is fixed to the rear plate of the paver by the connecting block 2 and the fixing bolt 3. The gas cylinder 6 is placed into the limiting platform 5. The compression of the semi-arc plate 7 causes the connecting plate 19 to slide on the sliding column 17, compressing the spring 18. The elastic force of the spring 18 causes the semi-arc plate 7 to lock the gas cylinder 6.
[0031] Working principle: When a quick-install paver heating device bracket is needed, the switch valve 8 on the gas tank 6 is opened. The gas passes through the fuel delivery pipe 19 and the high-frequency heating coil 16. The high-frequency heating coil 16 is set inside the heat-conducting cylinder 10. The heat-conducting cylinder 10 is made of aluminum, which has good thermal conductivity, allowing the heating wire 15 to quickly heat the inside of the heat-conducting cylinder 10. The heating wire 15 in the heat-conducting cylinder 10 heats the heat-conducting cylinder 10. The heat-conducting cylinder 10 is made of aluminum, which has good thermal conductivity, allowing the heating wire 15 to quickly heat the inside of the heat-conducting cylinder 10, thereby heating the gas in the high-frequency heating coil 16. The heated gas passes through the fuel delivery pipe 2 14. The gas flow rate can be controlled by the regulating valve 13. The pressure gauge 12 displays the pressure in the pipeline in real time. Finally, the gas is delivered to the heating nozzle 11, which heats the asphalt cold joint.
[0032] In addition, the mounting plate 1 is fixed to the rear plate of the paver by the connecting block 2 and the fixing bolt 3. The gas cylinder 6 is placed inside the limiting platform 5. The semi-circular plate 7 limits the gas cylinder 6. When the gas cylinder 6 is put in, the semi-circular plate 7 is squeezed to drive the connecting plate 19 to slide on the sliding column 17, compressing the spring 18. The elastic force of the spring 18 is used to make the semi-circular plate 7 tightly hold the gas cylinder 6, so as to achieve a stable installation.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
