Description

Technical Field

[0001] This invention relates to the field of road construction technology, and more specifically, to an asphalt paving device for road construction. Background Technology

[0002] Asphalt pavement refers to various types of pavement constructed by mixing road asphalt materials into mineral materials. Asphalt binder improves the ability of paving aggregates to resist damage to the pavement from traffic and natural factors, making the pavement smooth, dust-free, impermeable, and durable. Therefore, asphalt pavement is one of the most widely used high-grade pavements in road construction. The asphalt structural layer of asphalt pavement itself belongs to the category of flexible pavement, but its base layer can also be made of rigid cement concrete or semi-rigid hydraulic materials in addition to flexible materials. Asphalt paving equipment is required to lay asphalt during the construction of asphalt pavement.

[0003] Existing asphalt paving equipment used in road construction may experience engine failures, vibrations, automatic leveling failures, and hydraulic system failures during use. Overheating of the hydraulic system is one such failure, often caused by a covering on the radiator surface, which reduces the heat dissipation rate. To maintain the normal function of the hydraulic system, when the hydraulic system overheats, the asphalt paving equipment is usually shut down and the radiator is disassembled for cleaning. This not only delays the project progress but is also quite cumbersome. Therefore, there is an urgent need to design a new asphalt paving equipment for road construction. Summary of the Invention

[0024] Working principle: First, the asphalt paving machine 1 performs asphalt paving operations on the road. Then, the hydraulic oil in the hydraulic system inside the drive body 11 enters the sealing buffer groove 53, sealing notch 52, and central column cavity 405 through the inlet oil pipe 32, fixed cavity seat 31, and upstream oil pipe 33. It then passes through the channel formed by the corresponding central flat pipe 411, heat-dissipating pipe 409, left flat cavity 412, and right flat cavity 413, and enters the annular channel 406. Next, the hydraulic oil inside the annular channel 406 passes through the fluid passage 408, buffer disc cavity 407, downstream oil pipe 36, and positioning cavity seat 34, and is discharged into the hydraulic oil tank through the outlet oil pipe 35. Afterward, the heat in the hydraulic oil is transferred to the frame arm 403, heat-dissipating pipe 409, and heat-dissipating threaded plate 410 through heat conduction. Then, the frame arm 403... The heat pipe 409 and the centrally located flat tube 411 release heat into the air, achieving the initial heat dissipation effect. Next, the central control panel 14 detects the temperature of the hydraulic oil in the hydraulic system. When the hydraulic oil temperature exceeds the preset value inside the central control panel 14, the central control panel 14 controls the drive fan 27 to operate. Then, external air flows under the drive of the drive fan 27, passing through the filter screen 26. The filter screen 26 then filters the air, reducing the content of particulate matter and oil contaminants, thus slowing down the rate at which particulate matter and oil contaminants cover the heat dissipation component 4. Afterward, the air passes through the right air duct 613 and blows over the surface of the frame arm 403, the heat pipe 409, and the heat-dissipating threaded fins 410. Finally, the air is absorbed by the frame arm 403 and the heat pipe 409. The heat from the heat-dissipating threaded plate 410 raises its own temperature. Air then passes through the left air duct 612 and exits through the ventilation hole 29, achieving a second cooling effect. After running for a period of time, when the hydraulic oil temperature is still higher than the preset value inside the central control panel 14, the central control panel 14 controls the drive motor 38 to run. The drive motor 38 then rotates the drive wheel 39, which in turn rotates the cooling assembly 4 slowly via the drive belt 30. The area corresponding to the drive fan 27 continuously changes, and the heat-dissipating pipe 409, the central flat pipe 411, the left flat cavity 412, and the right flat cavity 413, all containing hydraulic oil, rotate to the lower side of the frame column 404. Then, the sealing piston column 51 blocks the corresponding end of the central flat pipe 411. Afterwards, the hydraulic oil inside the heat pipe 409, left flat cavity 412, and right flat cavity 413 on the lower side of the structural column 404 stops flowing. This is to increase the time the hydraulic oil stays inside the heat pipe 409, left flat cavity 412, and right flat cavity 413, thus extending the heat dissipation time and increasing the heat dissipation effect. Then, the central control panel 14 controls the booster pump 705 to run at low power. Next, the booster pump 705 draws flushing water through the clean water pipe 708 and the solenoid three-way valve 706, and pumps it into the front arc flat tube 711 and the rear arc flat tube 712 through the output pipe 709 and the branch pipe 710. Then, under the action of hydraulic pressure, the flushing water is sprayed onto the surface of the structural arm 403, heat pipe 409, heat-dissipating threaded plate 410, and rotating fly disc 401 through the cleaning head 713.The surfaces of the frame arm 403, heat pipe 409, heat-dissipating threaded plate 410, and rotating disc 401 are wetted. The water absorbs heat from these components and evaporates naturally, achieving a third heat dissipation effect. Next, the wetted components are aligned with the drive fan 27. The flowing air further accelerates the evaporation of water from these components, achieving a fourth heat dissipation effect. This excellent heat dissipation ensures the asphalt paving equipment can operate continuously in hot summer environments, enhancing its applicability. Okay, in this process, the heat in the air on the right side of the heat dissipation component 4 is transferred to the temperature sensing bulb 608 and temperature sensing bend 607 inside the right air duct 613, and the heat in the air on the left side of the heat dissipation component 4 is transferred to the temperature sensing bulb 608 and temperature sensing bend 607 inside the left air duct 612. Then, the temperature-sensing gas 609 inside the temperature sensing bend 607 and temperature sensing bulb 608 expands thermally and applies a thrust to the sealed piston 611. Because the temperature of the air on the left side of the heat dissipation component 4 is higher, the force on the sealed piston 611 on the left side of the displacement slide 605 is greater than the force on the other sealed piston 611. Then, the sealed piston 611 on the left side of the displacement slide 605 moves the displacement slide 605 to the right through the linkage rod 610. After that, the displacement slide 605... The contact spring 606 slides to the right on the bottom surface of the resistor strip 618, causing the length of the resistor strip 618 connected to the circuit to gradually shorten. Then, the current value through the resistor strip 618 gradually increases. Next, the displacement slide 605 moves to the right via its right-side linkage rod 610, causing another sealed piston 611 to move to the right. This pressurizes the temperature-sensing gas 609 inside the temperature-sensing bend 607 at the right end of the mounting plate 602, increasing the gas pressure until the gas pressure inside both temperature-sensing bends 607 is the same. At this point, the central control panel 14 records the current value through the resistor strip 618. However, as usage time increases, particles, oil, and other debris will accumulate on the temperature-sensing gas 609 and linkage rod 610, causing them to... As the heat dissipation effect gradually deteriorates, the hydraulic oil temperature becomes too high, while the temperature difference between the air on the left and right sides of the heat dissipation component 4 decreases. Then, the temperature-sensing gas 609 inside the temperature-sensing bend 607 at the left end of the mounting plate 602 cools down, its volume shrinks, and its pressure decreases. Consequently, the sealed piston 611 experiences a reduced force to the right. Then, under the pressure difference, the temperature-sensing gas 609 inside the temperature-sensing bend 607 on the right side of the mounting plate 602 exerts a leftward thrust on the sealed piston 611. This sealed piston 611 then moves to the left via the linkage rod 610, which in turn moves the displacement slide 605 to the left. The displacement slide 605 then moves the contact spring 606 to the left, increasing the length of the resistor strip 618 connected to the circuit. Consequently, the current flowing through the resistor strip 618 decreases.Then, the displacement slide 605 moves to the left via the linkage rod 610 at its left end, causing the sealed piston 611 on its left side to compress the corresponding temperature-sensing gas 609 until the pressure of the two temperature-sensing gases 609 is the same. Next, the central control panel 14 calculates the average current value of the original current value and the recorded current value. Then, when the current through the resistor bar 618 is less than the average current, the central control panel 14 controls the heat dissipation assembly 4 to rotate slowly. Simultaneously, the central control panel 14 controls the electromagnetic three-way valve 706 to activate. Then, the booster pump 705 is disconnected from the clean water pipe 708, while simultaneously connecting to the cleaning pipe 707. Next, the cleaning fluid, driven by the booster pump 705, is sprayed from the cleaning head 713 onto the heat dissipation assembly 4. The cleaning fluid then interacts with the covering material on the surface of the heat dissipation assembly 4, achieving a cleaning effect. Then, the central control panel 14 controls the solenoid three-way valve 706 to activate again. Next, the clean water pipe 708 connects to the booster pump 705, and the booster pump 705 disconnects from the cleaning pipe 707. The central control panel 14 then controls the booster pump 705 to operate at high power. Driven by the booster pump 705, the flushing water impacts the surfaces of the heat pipe 409, heat pipe threaded plate 410, frame arm 403, and rotating fly disc 401 through the cleaning head 713, washing away the cleaning fluid. The flushing wastewater is then discharged from the discharge hole 24 under the guidance of the guide slope 23. At the end of the flushing process, in high-temperature environments, the central control panel 14 controls the booster pump 705 to operate at low power; in lower-temperature environments, the central control panel 14 will control the booster pump 705 to shut down. This completes the automatic cleaning process.
