Description

Technical Field

[0001] This utility model relates to the field of asphalt transportation technology, specifically to an asphalt-insulated truck body that utilizes exhaust gas. Background Technology

[0002] In the production and transportation of asphalt, engineering vehicles are usually used for long-distance transport. During transportation, insulation cloth is typically used to cover and insulate the asphalt. However, some construction areas are far from the asphalt production site, and the asphalt is not laid immediately upon arrival at the construction area. It usually requires a long waiting period and is laid sequentially. Consequently, the temperature of the asphalt drops significantly during the long transportation waiting period, making it no longer suitable for the laying temperature. Therefore, this utility model provides an exhaust gas reuse asphalt insulation truck to solve the above-mentioned problems. Utility Model Content

[0003] The purpose of this invention is to provide an exhaust gas reuse asphalt-insulated truck body to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An exhaust gas reuse asphalt-insulated truck body includes a vehicle body, a truck bed installed at the rear end of the vehicle body, an exhaust gas box installed on the vehicle body, the interior of the exhaust gas box being connected to the exhaust gas exhaust end of the vehicle body, insulation square steel bars being installed at intervals on the side wall of the truck bed, and a connecting pipe being provided between the exhaust gas box and the insulation square steel bars, thus connecting the exhaust gas box and the insulation square steel bars through the connecting pipe.

[0005] As a further embodiment of this utility model, the connecting pipe includes a snap-fit ​​groove, which is a U-shaped groove. The snap-fit ​​groove is formed on the side wall of the exhaust box near the truck bed. A retaining ring, which is a U-shaped plate, is fixedly installed on the bottom inner side of the snap-fit ​​groove near the end of the truck bed. A connecting pipe is fixedly installed on the end of the truck bed near the exhaust box. The interior of the connecting pipe passes through the side wall of the truck bed near the exhaust box and is interconnected with the interior of the insulation square steel on both sides of the truck bed. A sealing ring is fitted on the outer wall of the connecting pipe. An adjusting spring is fixedly installed around the connecting pipe and the sealing ring at intervals.

[0006] As a further embodiment of this utility model, a transmission channel is provided between two adjacent sets of insulated square steel on both sides of the truck bed. The two ends of the transmission channel are respectively connected to the interior of the two sets of insulated square steel. Reinforcing columns are fixedly installed at intervals on the inner side of the insulated square steel corresponding to the connection position of the truck bed.

[0007] As a further embodiment of this utility model, a partition plate is fixedly installed inside the insulated square steel at the position corresponding to the rear end of the outer side of the truck bed. Two sets of fixed shafts are fixedly installed on the side of the partition plate near the exhaust gas box, and the ends of the two sets of fixed shafts away from the partition plate are respectively fixedly installed on the top and bottom ends of the inner side of the insulated square steel. Opening and closing plates are movably installed on the fixed shafts, and the ends of the two sets of opening and closing plates away from the fixed shafts are in contact with each other. A return torsion spring is provided on the inner side of the opening and closing plates.

[0008] As a further embodiment of this utility model, a baffle is provided at the front end of the opening and closing plate, and the baffle is fixedly installed on the partition plate and the inner wall of the heat-insulating square steel.

[0009] As a further embodiment of this utility model, a rotating shaft is fixedly installed at the end of the partition plate away from the closing plate, and the end of the rotating shaft away from the partition plate is fixedly installed on the inner wall of the heat-insulating square steel. A buffer plate is movably fitted on the rotating shaft, and the buffer plate can rotate on the rotating shaft. The gap area between the two sets of opening and closing plates and the buffer plate is a buffer zone.

[0010] As a further embodiment of this utility model, a temporary storage groove is provided on the inner side of the partition plate and the insulation square steel near the opening and closing plate. Temporary storage plates are fixedly installed at intervals inside the temporary storage groove. An expansion groove is provided on the side wall of the opening and closing plate corresponding to the position of the temporary storage groove. A locking block is provided inside the expansion groove. A return spring is fixedly installed at the end of the locking block away from the temporary storage groove. The end of the return spring away from the locking block is fixedly installed inside the expansion groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. When this utility model is used, the high-temperature exhaust gas generated by the vehicle engine is introduced into the heat-insulating square steel of the side wall of the truck bed, and the waste heat is directly used to insulate the asphalt in the truck bed. No additional fuel or electricity is required, which greatly improves the heat insulation effect of the asphalt in the truck bed during transportation waiting. It also realizes the recovery and utilization of waste heat and reduces heat emissions.

[0012] 2. When this utility model is in use, the truck bed is reset, the pipeline is automatically connected and sealed, and the exhaust gas can preheat the empty truck bed again. This design avoids the sudden cooling phenomenon caused by directly loading hot asphalt into a cold truck bed, protects the truck bed, and prepares it for the next transportation. It realizes intelligent insulation throughout the entire cycle from loading, transportation, unloading to return.

[0013] 3. When this utility model is used, the mechanical delay reset mechanism composed of the temporary groove, the temporary plate, the telescopic groove on the opening and closing plate, the locking block, and the reset spring ensures that the opening and closing plate will not close instantly after the exhaust is opened. Instead, the locking block needs to pass over the temporary plate to gradually reset. This process ensures that the system can fully exhaust a portion of the cooled exhaust gas to make way for the newly generated high-temperature exhaust gas, thereby continuously optimizing the system's heat preservation efficiency.

[0014] 4. When this utility model is used, the buffer zone composed of the buffer plate and the rotating shaft and the second exhaust port are spatially separated. The buffer plate does not need to be reset torsion spring and can swing to exhaust gas when the vehicle is bumpy, ensuring that the pressure of the buffer zone is released in time and avoiding excessive pressure from affecting the normal opening of the opening and closing plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figures 1-6In this embodiment of the utility model, an exhaust gas reuse asphalt insulation truck body includes a vehicle body 1, a truck bed 2 installed at the rear end of the vehicle body 1, the truck bed 2 being able to tilt and lift at the rear end of the vehicle body 1 via a hydraulic rod, an exhaust gas box 4 also being installed on the vehicle body 1, the interior of the exhaust gas box 4 being interconnected with the exhaust gas exhaust end of the vehicle body 1, insulation square steel 3 being installed at intervals on the side wall of the truck bed 2, a connecting pipe being provided between the exhaust gas box 4 and the insulation square steel 3, the exhaust gas box 4 being able to transfer the exhaust gas generated by the vehicle body 1 to the insulation square steel 3, and the insulation square steel 3 being used to insulate the material inside the truck bed 2.

[0024] The connecting pipe includes a snap-fit ​​groove 5, which is a U-shaped groove. The snap-fit ​​groove 5 is located on the side wall of the exhaust box 4 near the truck bed 2. A retaining ring 6, which is a U-shaped plate, is fixedly installed on the bottom inner side of the snap-fit ​​groove 5 near the end of the truck bed 2. A connecting pipe 7 is fixedly installed on the end of the truck bed 2 near the exhaust box 4. The interior of the connecting pipe 7 passes through the side wall of the truck bed 2 near the exhaust box 4 and is interconnected with the interior of the insulation square steel 3 on both sides of the truck bed 2. A sealing ring 8 is fitted on the outer wall of the connecting pipe 7. An adjusting spring 9 is fixedly installed around the connecting pipe 7 and the sealing ring 8 at intervals. By adjusting the spring 9, the sealing ring 8 can be elastically adjusted and moved on the side wall of the connecting pipe 7. The thickness of the sealing ring 8 is matched with the distance between the retaining ring 6 and the inner wall of the snap-fit ​​groove 5. The interior of the connecting pipe 7 passes through the corresponding position of the inner wall of the snap-fit ​​groove 5 and is interconnected with the interior of the exhaust box 4.

[0025] When the truck bed 2 is not tilted, the connecting pipe 7 on the truck bed 2 will cause the sealing ring 8 to snap into the inside of the snap-in groove 5. Under the pressure of the retaining ring 6, the sealing ring 8 will be squeezed and move away from the side of the truck bed 2, and fit tightly against the inner wall of the snap-in groove 5, thus sealing the connection between the snap-in groove 5 and the connecting pipe 7. At this time, the vehicle will generate exhaust gas during starting and driving. The exhaust gas will be transmitted to the insulated square steel 3 on the truck bed 2 through the exhaust gas box 4 and the connecting pipe 7, thus insulating the internal material of the truck bed 2. When the truck bed 2 is tilted, the end of the truck bed 2 near the exhaust gas box 4 will be lifted, thereby causing the connecting pipe 7 and the sealing ring 8 to separate from the snap-in groove 5. At this time, the ends of the snap-in groove 5 and the connecting pipe 7 that are close to each other are exposed to the air. At this time, the exhaust gas of the vehicle and the exhaust gas stored inside the insulated square steel 3 will be discharged through the snap-in groove 5 and the connecting pipe 7 respectively.

[0026] The two side walls of the truck bed 2 are provided with transmission channels 10 between the two adjacent sets of insulated square steel 3. The two ends of the transmission channels 10 are respectively connected to the interior of the two sets of insulated square steel 3. Reinforcing columns 11 are fixedly installed at intervals on the inner side of the insulated square steel 3 corresponding to the connection position of the truck bed 2. The two side walls of the truck bed 2 are reinforced by the reinforcing columns 11.

[0027] A partition plate 12 is fixedly installed inside the insulated square steel 3 at the rear end of the outer side of the truck bed 2. The partition plate 12 is rectangular and forms a rectangular channel at the rear end of the insulated square steel 3. Two sets of fixed shafts 15 are fixedly installed on the side of the partition plate 12 near the exhaust box 4. The ends of the two sets of fixed shafts 15 away from the partition plate 12 are respectively fixedly installed at the top and bottom of the inner side of the insulated square steel 3. Opening and closing plates 14 are movably installed on the fixed shafts 15. The ends of the two sets of opening and closing plates 14 away from the fixed shafts 15 are in contact with each other. The opening and closing plates 14 can rotate on the fixed shafts 15. A return torsion spring 16 is provided inside the opening and closing plates 14. The return torsion spring 16 makes the opening and closing plates 14 and the fixed shafts 15 movably connected. The return torsion spring 16 can drive the opening and closing plates 14 to return to their original position after rotation.

[0028] In the initial state, the two sets of opening and closing plates 14 are in a closed state. When the amount of waste gas stored inside the insulation square steel 3 is too large, the airflow pressure inside the insulation square steel 3 will act on the opening and closing plates 14, causing the two sets of opening and closing plates 14 to separate, thereby discharging the excess waste gas.

[0029] A baffle 13 is provided at the front end of the opening and closing plate 14. The baffle 13 is fixedly installed on the inner wall of the partition plate 12 and the heat-insulating square steel 3. The baffle 13 can prevent the opening and closing plate 14 from rotating towards the exhaust gas box 4.

[0030] A rotating shaft 18 is fixedly installed at one end of the partition plate 12 away from the closing plate 14. The other end of the rotating shaft 18 away from the partition plate 12 is fixedly installed on the inner wall of the insulated square steel 3. A buffer plate 17 is movably mounted on the rotating shaft 18. The buffer plate 17 can rotate on the rotating shaft 18. The gap area between the two sets of opening and closing plates 14 and the buffer plate 17 is a buffer zone. The buffer zone allows excess exhaust gas to be temporarily retained in the area. As exhaust gas accumulates, the pressure in the buffer zone gradually increases, which will push the buffer plate 17 to open and discharge.

[0031] Furthermore, the opening of the two sets of opening and closing plates 14 and the opening of the buffer plate 17 are completely independent, which can effectively separate the effective exhaust gas and the overflow exhaust gas, that is, the overflow exhaust gas can be discharged separately, which can reduce the occurrence of a large amount of exhaust gas overflow.

[0032] Furthermore, by buffering the overflowing exhaust gas within the buffer zone, the interference of external airflow on the effective exhaust gas inside the insulated square steel 3 can be effectively reduced.

[0033] Furthermore, the connection between the rotating shaft 18 and the buffer plate 17 is not exactly the same as that between the opening and closing plate 14 and the fixed shaft 15. The buffer plate 17 and the rotating shaft 18 lack a reset torsion spring 16 for reset adjustment. Therefore, during vehicle operation, due to bumps and inertia, the buffer plate 17 can also swing on the rotating shaft 18, thereby allowing the exhaust gas in the buffer zone to be discharged during operation. This avoids the situation where the exhaust gas pressure in the buffer zone is too high, resulting in the inability to discharge excess exhaust gas inside the insulation square steel 3 in time (i.e., when the pressure areas on both sides of the opening and closing plate 14 are the same, the opening and closing plate 14 cannot be opened, and the length of the side of the opening and closing plate 14 away from the buffer zone is too long, so the length of the buffer zone is short. Therefore, when there is a small amount of exhaust gas in the buffer zone, it can generate resistance to the opening and closing plate 14).

[0034] A temporary storage groove 19 is provided on the inner side of the partition plate 12 and the insulation square steel 3 near the opening and closing plate 14. The temporary storage groove 19 is an arc-shaped groove. The axis of the temporary storage groove 19 corresponds to the axis of the opening and closing plate 14. The temporary storage groove 19 is located in the buffer zone. A temporary storage plate 20 is fixedly installed inside the temporary storage groove 19 at intervals. A telescopic groove 21 is provided on the side wall of the opening and closing plate 14 corresponding to the position of the temporary storage groove 19. A locking block 22 is provided inside the telescopic groove 21. The end of the locking block 22 near the temporary storage groove 19 is arc-shaped. A return spring 23 is fixedly installed on the end of the locking block 22 away from the temporary storage groove 19. The end of the return spring 23 away from the locking block 22 is fixedly installed in the telescopic groove 21.

[0035] When the opening and closing plate 14 is opened under pressure, it rotates, causing the locking block 22 to move within the temporary groove 19. Depending on the pressure, the locking block 22 retracts into the telescopic groove 21 via the return spring 23, allowing the opening and closing plate 14 to be adjusted to the designated position. When the internal pressure of the insulation square steel 3 decreases, the opening and closing plate 14 does not immediately reset via the return torsion spring 16. Instead, the torque of the return torsion spring 16 causes the opening and closing plate 14 to rotate and reset, bringing the locking block 22 into contact with the temporary plate 20. The locking block 22 then retracts into the telescopic groove 21 via the return spring 23, allowing it to pass over the temporary plate 20 and gradually reset the opening and closing plate 14. This effectively discharges excess waste gas, allowing a large amount of cooled waste gas to escape, and enabling subsequent newly generated waste gas to quickly and effectively fill the gap.

[0036] The working principle of this utility model is as follows: When this utility model is in use, the material is poured into the inside of the truck bed 2, and the top of the truck bed 2 is covered with an insulation cloth. By starting the vehicle body 1, it travels to the designated location for transportation. During the travel of the vehicle body 1, the vehicle body 1 will generate exhaust gas, which is transmitted to the inside of the insulation square steel 3 on the side wall of the truck bed 2 through the exhaust gas box 4 and the connecting pipe 7. The heat of the exhaust gas is used to insulate the material inside the truck bed 2. At the same time, the excess exhaust gas will be discharged through the buffer zone. When the designated location is reached, the truck bed 2 is tilted and raised by the control of the vehicle body 1. At this time, the material inside the truck bed 2 will be poured into the designated location. At the same time, the connecting pipe 7 will separate from the buckle groove 5, so that the exhaust gas of the vehicle body 1 and the exhaust gas inside the insulation square steel 3 will be discharged through the buckle groove 5 and the connecting pipe 7 respectively. After the material is completely discharged, the vehicle body 1 controls the truck bed 2 to reset, so that the connecting pipe 7 on the truck bed 2 drives the sealing ring 8 to snap into the snap groove 5 on the exhaust box 4, so that the vehicle exhaust will continue to be transmitted into the interior of the insulated square steel 3. With the top of the truck bed 2 sealed, the interior of the truck bed 2 can be preheated and insulated when the vehicle body 1 returns to the material loading point, so as to avoid sudden cooling when the material is dumped.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
