In this embodiment, the heating system for the carriage of the dump truck comprises a heater 1, a heating air duct formed on the carriage 7, a connecting assembly and a transition assembly.
In the present embodiment, the fuel heater 1 is used as the heater 1. Specifically, fig. 1 to 4 show the structure of the heater 1 described above.
The heater 1 includes a rectangular parallelepiped case 10, and the shape of the case 10 is not particularly limited, and may be modified by those skilled in the art according to the actual situation. Two main machines 11 for exhausting air and heating and then discharging are arranged in parallel in the shell 10. The main unit 11 uses fuel oil as fuel. The two ends of the main machine 11 are respectively an air inlet pipe 12 and an air outlet pipe 13 for air suction and discharge.
In the housing 10, a cold air partition 16 and a hot air partition 17 are respectively disposed at two ends of the main body 11. A cold air area 14 is formed between the cold air partition 16 and the shell 10, and a hot air area 15 is formed between the hot air partition 17 and the shell 10. An air inlet pipe 12 at the end part of the main machine 11 is arranged on a cold air partition plate 16 in a penetrating way, and an air outlet pipe 13 is arranged on a hot air partition plate 17 in a penetrating way. The mouth of the air inlet pipe 12 is positioned in the cold air area 14, and the mouth of the air outlet pipe 13 is positioned in the hot air area 15.
An air inlet (not shown) and an air outlet (not shown) are formed in the housing 10, the air inlet is located on the housing 10 at the position of the cold air area 14, and the air outlet is located on the housing 10 at the position of the hot air area 15. The air inlet is communicated to an air inlet pipe 12 at the end part of the host machine 11 through a cold air area 14, and the air outlet is communicated to an air outlet pipe 13 at the end part of the host machine 11 through a hot air area 15.
One end of the oil pipe 51 is communicated to the oil tank 50, and the other end is connected to the oil pump and then passes through the shell 10 to be connected to the host 11 in the shell 10. The oil pump can pump fuel into the main machine 11 to ensure the normal operation of the main machine 11.
Meanwhile, the bottom of the casing 10 is provided with an air inlet pipe 53, one end of the air inlet pipe 53 penetrates through the casing 10 and is connected to the host 11, the other end of the air inlet pipe 53 is connected with the air filter 52, and when the host 11 works, the host 11 extracts clean air through the air inlet pipe 53 and the air filter 52 to work.
The bottom parts of the two main machines 11 are connected with tail gas pipes 19, and high-temperature tail gas generated by the operation of the main machines 11 is discharged through the tail gas pipes 19. In this embodiment, it is necessary to utilize high-temperature exhaust gas generated by the operation of the main unit 11, thereby improving the heating efficiency. Thus, both tail gas pipes 19 are connected to the exhaust pipe 18. The exhaust pipe 18 is a tee having two inlets and one outlet. The two inlets are respectively communicated with two tail gas pipes 19, and the outlet passes through the shell 10 and is discharged after being utilized by a pipeline.
In the present embodiment, the heater 1 is fixed by the fixing bracket 4.
The heater 1 is provided with a connecting assembly, specifically referring to fig. 2, the connecting assembly includes an air inlet connecting pipe 30, an air outlet connecting pipe 31, a tail gas connecting pipe 34, a first buffer spring 32, a second buffer spring 35, a first connecting member 33, and a second connecting member 36.
The air inlet connecting pipe 30 is fixed on the shell 10 of the heater 1, the air inlet connecting pipe 30 is specifically arranged at the position of the air inlet, and the air inlet connecting pipe 30 is communicated with the air inlet. Similarly, the outlet connecting pipe 31 is fixed on the casing 10 of the heater 1 at the position of the outlet and is communicated with the outlet. An exhaust gas connection pipe 34 is fixed to the exhaust pipe 18 passing through the casing 10, and the exhaust gas connection pipe 34 communicates with the exhaust pipe 18.
The air inlet connecting pipe 30 and the air outlet connecting pipe 31 are both sleeved with a first connecting piece 33. The first connecting member 33 is tubular with a flange piece formed at an upper end portion. The first connecting member 33 on the air inlet connecting pipe 30 can move axially along the air inlet connecting pipe 30, and the first connecting member 33 on the air outlet connecting pipe 31 can move axially along the air outlet connecting pipe 31. The first substantially tubular connecting member 33 is less prone to deflection relative to the axial direction during movement and to become jammed.
Meanwhile, the air inlet connecting pipe 30 and the air outlet connecting pipe 31 are both sleeved with a first buffer spring 32, the first buffer spring 32 is located below the first connecting piece 33, two ends of the first buffer spring respectively abut against the heater 1 and the first connecting piece 33, and the first connecting piece 33 is elastically supported upwards.
Similarly, the tail gas connecting pipe 34 is sleeved with a second buffer spring 35 and a second connecting piece 36. The second connecting member 36 has a tubular shape with a flange piece formed at an upper end portion thereof. The second connecting member 36 is axially movable along the exhaust gas connecting pipe 34. The second generally tubular connector 36 is less prone to deflection relative to the axial direction during movement and to binding. The second buffer spring 35 is located below the second connecting member 36, and both ends thereof respectively abut against the end of the exhaust pipe 18 and the second connecting member 36, and elastically support the second connecting member 36 upward.
The transition assembly comprises a transition support 20, an air inlet transition pipe 21, an air outlet transition pipe 23 and a tail gas transition pipe 25. The transition support 20 is used for bearing the air inlet transition pipe 21, the air outlet transition pipe 23 and the tail gas transition pipe 25.
As shown in fig. 5 to 8, the oil tank 50 is fixed to the vehicle frame 6, and the heater 1 is fixed to the vehicle frame 6 via the fixing bracket 4. The connection assembly is fixed to the heater 1.
The transition support 20 is fixed to the bottom of the vehicle compartment 7. The air inlet transition pipe 21, the air outlet transition pipe 23 and the tail gas transition pipe 25 are all fixed on the transition support 20. When the carriage 7 unloads the material, the transition bracket 20 will drive the air inlet transition pipe 21, the air outlet transition pipe 23 and the tail gas transition pipe 25 to lift and lower along with the carriage 7. Therefore, the air inlet transition pipe 21, the air outlet transition pipe 23, and the tail gas transition pipe 25 need to be separated from the air inlet connection pipe 30, the air outlet connection pipe 31, and the tail gas connection pipe 34. Meanwhile, in order to ensure that the hot air and the high-temperature tail gas generated by the heater 1 can effectively circulate to the heating air duct, the arrangement positions of the air inlet transition pipe 21, the air outlet transition pipe 23 and the tail gas transition pipe 25 on the transition support 20 need to ensure that the air inlet transition pipe 21, the air outlet transition pipe 23 and the tail gas transition pipe 25 are respectively communicated with the air inlet connecting pipe 30, the air outlet connecting pipe 31 and the tail gas connecting pipe 34 when the carriage 7 is placed.
Specifically, the air inlet transition pipe 21, the air outlet transition pipe 23, and the tail gas transition pipe 25 need to be fixed on the transition support 20, and the pipe orifices are all opened downwards on the transition support 20. When the car 7 is lowered, the transition bracket 20 presses the first link 33 and the second link 36 downward. The first connecting piece 33 and the second connecting piece 36 are tightly attached to the transition support 20 under the action of the first buffer spring 32 and the second buffer spring 35, and the air inlet connecting pipe 30, the air outlet connecting pipe 31 and the tail gas connecting pipe 34 respectively extend into the air inlet transition pipe 21, the air outlet transition pipe 23 and the tail gas transition pipe 25, so that the air inlet connecting pipe 30, the air outlet connecting pipe 31 and the tail gas connecting pipe 34 are respectively communicated with the air inlet transition pipe 21, the air outlet transition pipe 23 and the tail gas transition pipe 25. At this time, through the cooperation of the transition bracket 20, the first connecting member 33, the second connecting member 36, the first buffer spring 32 and the second buffer spring 35, the effective communication between the air inlet connecting pipe 30 and the air inlet transition pipe 21, between the air outlet connecting pipe 31 and the air outlet transition pipe 23, and between the tail gas connecting pipe 34 and the tail gas transition pipe 25 can be realized.

Two first partition plates 80 are further provided between the first wind hole 70 and the second wind hole 77.
The reinforcing ribs serving as reinforcing functions usually extend from the front end of the carriage 7 to the tail end of the carriage 7, and in the embodiment, the arrangement of the heating air duct can realize effective heating without covering the whole carriage 7, and ensures that the carriage 7 has no residue and adhesion when unloading materials. Specifically, a second partition plate 81 and a third partition plate 82 are provided in the middle of the hollow second bead 72 and the fourth bead 76, respectively. At this time, the hollow pipe section between the second partition plate 81 and the first bead 71 in the second bead 72 is the second ventilation pipe. In the fourth reinforcing rib 76, a hollow pipe section between the third partition plate 82 and the first reinforcing rib 71 is a fourth ventilation pipe.
In the second bead 72, a first communication hole 73 that penetrates downward through the second bead 72 and the floor of the vehicle compartment 7 is formed on the side of the second partition plate 81 facing the first bead 71.
In the third bead 74, a second communication hole 75 is formed on the fourth partition plate on the side facing the first bead 71 so as to penetrate downward through the fourth bead 76 and the floor of the vehicle compartment 7.
A hollow third reinforcing bead 74, which is conventionally used for reinforcement, is also fixed to the bottom of the vehicle compartment 7. Both ends of the third bead 74 extend to the side edge of the vehicle compartment 7 in the width direction of the vehicle compartment 7, and the first communication hole 73 and the second communication hole 75 communicate the inside of the third bead 74 with the inside of the second bead 72 and the fourth bead 76 at both ends of the third bead 74, respectively. The third reinforcing rib 74 is the third ventilation pipe.

The exhaust gas transition pipe 25 is connected with the fifth reinforcing ribs 78, and the inside of the exhaust gas transition pipe 25 is communicated with the inside of the fifth reinforcing ribs 78.
The operation of the dump truck body heating system will be described in detail with reference to the structures shown in fig. 1 to 12.
When carriage 7 is the state of transferring, transition support 20 extrudees first connecting piece 33 and second connecting piece 36 downwards, and air-out connecting pipe 31 effectively communicates with air-out transition pipe 23, and air inlet connecting pipe 30 and air inlet transition pipe 21 effectively communicate, and tail gas connecting pipe 34 and tail gas transition pipe 25 effectively communicate.
Hot air generated by the operation of the host machine 11 in the heater 1 enters the hot air area 15 from the air outlet pipe 13, enters the air outlet connecting pipe 31 through an air outlet on the casing 10, enters the first reinforcing rib 71 through the air outlet transition pipe 23 and the first air hole 70, flows along the first reinforcing rib 71 and the second reinforcing rib 72, passes through the first communication hole 73, enters the third reinforcing rib 74, passes through the second communication hole 75, enters the fourth reinforcing rib 76, enters the first reinforcing rib 71 again, flows into the air inlet transition pipe 21 from the second air hole 77, enters the cold air area 14 in the casing 10 through the air inlet connecting pipe 30 and the air inlet, and enters the host machine 11 through the air inlet pipe 12 under the suction effect of the host machine 11 to be heated.
When the hot air flows through the heating air duct, heat exchange is performed continuously to heat the carriage 7 at the position of the heating air duct. The cooled air flow after continuous heat exchange returns to the main machine 11 to be heated again, and then the process is repeated to perform continuous circulation heating.
Meanwhile, during the operation of the main engine 11, air enters the main engine 11 through the air filter 52 and the air inlet pipe 53 for fuel oil combustion. The exhaust gas formed after the fuel in the main engine 11 is combusted is collected at the exhaust pipe 18 from the exhaust pipe 19, flows to the exhaust gas connecting pipe 34 through the exhaust pipe 18, then enters the fifth reinforcing ribs 78 through the exhaust gas transition pipe 25, and flows to the end parts of the fifth reinforcing ribs 78 along the fifth reinforcing ribs 78, and is discharged through the exhaust gas holes 79.
When flowing along the fifth strengthening ribs 78, the high-temperature exhaust gas also exchanges heat with the vehicle compartment 7 near the fifth strengthening ribs 78, thereby achieving auxiliary heating.
When the carriage 7 is lifted for unloading, the transition bracket 20 drives the air outlet transition pipe 23, the air inlet transition pipe 21 and the tail gas transition pipe 25 to be lifted synchronously, and the air outlet transition pipe 23, the air inlet transition pipe 21 and the tail gas transition pipe 25 are separated from the air outlet connecting pipe 31, the air inlet connecting pipe 30 and the tail gas connecting pipe 34 respectively. The heater 1 stops working and no air flow flows in the heating air duct.
