Description

Technical fields:

[0001] This utility model relates to the field of dump truck technology, and in particular to a novel heat-generating and heat-insulating truck body structure. Background technology:

[0002] Currently, bulk material dump trucks on the market can be used to transport water and sand as well as asphalt mixtures. In the low-temperature environment of Northeast China during winter, water and sand are prone to freezing during transportation, making unloading difficult. Asphalt mixtures are transported from the asphalt mixing plant to the construction site at an average distance of 20 to 30 kilometers. Asphalt mixtures require certain insulation of the truck bed during transportation. If the insulation of the truck bed is poor, the temperature of the asphalt mixture will drop significantly during transportation. If the temperature of the asphalt mixture is too low, it is easy to produce waste. After arriving at the construction site, some asphalt mixture cannot be used, resulting in waste. At present, there is no good solution to the above problems.

[0003] In summary, how to solve the problem of heat preservation of the carriage during transportation has become a technical challenge that urgently needs to be addressed in the industry. Utility model content:

[0004] To overcome the shortcomings of existing technologies, this utility model provides a novel heat-generating and heat-insulating carriage structure, which solves the problems of water and sand freezing and being difficult to unload during transportation, and asphalt mixtures being prone to waste during transportation, caused by the poor heat insulation effect of previous carriages.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A novel heat-generating and heat-insulating vehicle body structure includes a vehicle body. A heat-conducting oil pipe is installed inside the side wall of the vehicle body. The heat-conducting oil pipe is connected to a heat-conducting oil heating device and a circulating oil pump located outside the vehicle body. The heat-conducting oil heating device includes a power take-off (PTO) mounted on the vehicle frame. The input end of the PTO is connected to the vehicle engine, and the output end of the PTO is connected to a hydraulic oil pump. The hydraulic oil pump is connected to a hydraulic motor via a pipeline and a hydraulic valve group. The hydraulic motor is connected to a permanent magnet eddy current heater. The permanent magnet eddy current heater has a heat-conducting oil chamber. The inlet and outlet of the heat-conducting oil chamber are respectively connected to both ends of the heat-conducting oil pipe.

[0007] The side wall of the carriage is provided with an insulation layer located outside the heat-conducting oil pipe.

[0008] The heat-conducting oil pipe is also equipped with a heat-conducting oil tank.

[0009] The hydraulic motor has a permanent magnet rotor for a permanent magnet eddy current heater and a circulating oil pump installed on its output shaft. The hydraulic motor drives both the permanent magnet eddy current heater and the circulating oil pump.

[0010] The permanent magnet eddy current heater is equipped with a metal shell, and the heat-conducting oil cavity is located on the metal shell.

[0011] The present invention adopts the above solution and has the following advantages:

[0012] Power is taken from the vehicle engine via a power take-off (PTO), eliminating additional energy consumption and promoting energy conservation and environmental protection. The PTO then drives a hydraulic oil pump, which in turn drives a hydraulic motor via a hydraulic valve group. The speed of the hydraulic motor can be controlled by the hydraulic valve group. The hydraulic motor is connected to a permanent magnet eddy current heater, which drives the permanent magnet rotor of the heater to rotate, generating eddy currents and thus producing heat. This results in high heating efficiency. The permanent magnet eddy current heater has a heat-conducting oil chamber, where the heat raises the temperature of the heat-conducting oil. The hydraulic motor drives the permanent magnet eddy current heater and the circulating oil pump simultaneously, achieving synchronous drive. The structure is simple and compact, allowing the heated heat-conducting oil to flow in heat-conducting oil pipes arranged on the side wall of the truck bed. This heats or maintains the temperature of the truck bed, effectively preventing water and sand from freezing during transportation and avoiding excessive temperature drop of the asphalt mixture during transportation, thus ensuring the transportation quality of the asphalt mixture.

[0015] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0016] like Figure 1 As shown, a novel heat-generating and heat-insulating carriage structure includes a carriage 1. A heat-conducting oil pipe 2 is provided inside the side wall of the carriage 1. The heat-conducting oil pipe 2 is connected to a heat-conducting oil heating device and a circulating oil pump 3 located on the outside of the carriage 1. The heat-conducting oil heating device includes a power take-off 5 mounted on a frame 4. The input end of the power take-off 5 is connected to the automobile engine, and the output end of the power take-off 5 is connected to a hydraulic oil pump 6. The hydraulic oil pump 6 is connected to a hydraulic motor 8 through a pipeline and a hydraulic valve group 7. The hydraulic motor 8 is connected to a permanent magnet eddy current heater 9. The permanent magnet eddy current heater 9 is provided with a heat-conducting oil chamber 10. The oil inlet and oil outlet of the heat-conducting oil chamber 10 are respectively connected to the two ends of the heat-conducting oil pipe 2.

[0017] The side wall of the carriage 1 is provided with an insulation layer located outside the heat-conducting oil pipe 2. This can prevent the heat from the heat-conducting oil pipe 2 from dissipating to the outside of the carriage 1, and allow the heat to accumulate to the inside of the carriage 1, thereby improving the heat preservation and heating effect.

[0018] The heat transfer oil pipe 2 is also equipped with a heat transfer oil tank 11, which can store heat transfer oil and also add heat transfer oil through the heat transfer oil tank 11.

[0019] The permanent magnet rotor 12 of the permanent magnet eddy current heater 9 and the circulating oil pump 3 are simultaneously installed on the output shaft of the hydraulic motor 8. The hydraulic motor 8 drives the permanent magnet eddy current heater 9 and the circulating oil pump 3 at the same time. While the hydraulic motor 8 drives the permanent magnet rotor 12 to rotate, it can also drive the circulating oil pump 3 to work, so as to achieve synchronous drive.

[0020] The permanent magnet eddy current heater 9 is provided with a metal shell 13, and the heat conduction oil cavity 10 is provided on the metal shell 13. The metal shell 13 has a better heat conduction effect, which makes it easier to transfer the heat of the permanent magnet eddy current heater 9 to the heat conduction oil in the heat conduction oil cavity 10.

[0021] Working principle:

[0022] When the car engine is running, it drives the power take-off (PTO) 5 to take power, which in turn drives the hydraulic oil pump 6. The hydraulic oil pump 6 drives the hydraulic motor 8 via the hydraulic valve group 7. The speed of the hydraulic motor 8 can be controlled by the hydraulic valve group 7, thereby controlling the heating efficiency of the permanent magnet eddy current heater 9 and the circulation efficiency of the circulating oil pump 3. The hydraulic motor 8 is connected to the permanent magnet eddy current heater 9 and can drive the permanent magnet rotor 12 of the permanent magnet eddy current heater 9 to rotate and generate eddy currents, thereby generating heat. The permanent magnet eddy current heater 9 is provided with a heat-conducting oil chamber 10. After the heat is transferred through the metal shell 13, it can heat the heat-conducting oil in the heat-conducting oil chamber 10 and raise its temperature. The hydraulic motor 8 drives the permanent magnet eddy current heater 9 and the circulating oil pump 3 at the same time, achieving synchronous drive. The circulating oil pump 3 makes the heated heat-conducting oil flow in the heat-conducting oil pipe 2 arranged on the side wall of the carriage 1, thereby heating or maintaining the temperature of the carriage 1, effectively preventing water and sand from freezing during transportation, preventing excessive temperature decay of the asphalt mixture during transportation, and ensuring the transportation quality of the asphalt mixture.

[0023] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0024] Any aspects of this utility model not described in detail are known to those skilled in the art.
