Description

Technical Field

[0001] The utility model relates to the field of truck bottom compartment heating, in particular to a bottom compartment heating system for a mining dump truck. Background Art

[0002] A mining dump truck is a heavy-duty dump truck used in off-road environments. It has the characteristics of heavy load capacity and short haul distance and is specially used for transporting bulk materials in open-pit mines.

[0003] The body heating system of the wide-body dump truck for mining is discharged from the engine exhaust pipe through the frame channel steel on both sides of the bottom body. The heating area is only at the edges of both sides of the bottom body, and can only heat a local area, which accounts for a small proportion of the overall area of the bottom of the car body. In winter, when mining trucks transport materials, due to the high moisture content and severe cold weather, the materials are frozen and stuck to the bottom of the car body, and the materials cannot be smoothly unloaded in the spoil yard. Hydraulic excavators are needed to assist in excavating the frozen and sticky materials in the car body. The side walls of the car body are not heated, and there is also a phenomenon of sticking materials on the side walls, which poses a safety hazard and low material transportation efficiency. It is urgent to achieve full heating of the bottom and side walls of the car body to completely solve the problem of frozen and sticky materials. Utility Model Content

[0022] See also Figures 1 to 4The utility model provides a technical solution: a bottom compartment heating system for a mining dump truck, comprising a truck body 1 and a truck compartment 2, characterized in that: the truck compartment 2 is rotatably connected to the rear side of the truck body 1 through a lifting cylinder, the truck compartment 2 comprises a top compartment 3 and a vehicle beam 4, the vehicle beam 4 is fixedly connected to the bottom end of the top compartment 3, the vehicle beam 4 comprises a longitudinal main channel steel 41, a transverse main channel steel 42, a steering exhaust pipe 43, an exhaust hole 44 and a smoke exhaust hole 45, the longitudinal main channel steel 41 is provided with five groups, the transverse main channel steel 42 is provided with several groups, the longitudinal main channel steel 41 and the transverse main channel steel 42 are both hollow structures, the longitudinal main channel steel 41 and the transverse main channel steel 42 are staggered and penetrate each other, the front end of the longitudinal main channel steel 41 is provided with an opening, the steering exhaust pipe 43 is rotatably connected in the opening, the exhaust hole 44 designed to be penetrated is provided at the tail end of the longitudinal main channel steel 41, and the smoke exhaust hole 45 is provided at the tail ends of the two groups of longitudinal main channel steels 41 on both sides of the middle;

[0023] The truck compartment 2 expands the contact area between the compartment and the high-temperature exhaust gas, ensuring that the heat generated by the high-temperature exhaust gas can more evenly and fully cover the inner wall of the compartment, effectively reducing the temperature difference between the stripped material and the compartment. This improvement not only significantly reduces the adhesion between the material and the compartment, but also makes it easier for the material to be discharged smoothly from the compartment, significantly improving the discharge efficiency and operation continuity. At the same time, the smoothness of the transportation process is enhanced, reducing the time delay caused by cleaning the sticking material, and further improving the overall transportation efficiency and the execution of the production plan;

[0024] The top compartment 3 includes a top compartment body 31, a first manganese steel plate 32, a second manganese steel plate 33, a third manganese steel plate 34 and square heat-conducting air holes 35. The first manganese steel plate 32, the second manganese steel plate 33 and the third manganese steel plate 34 are welded and fixed to the inner wall of the top compartment body 31. The first manganese steel plate 32 and the second manganese steel plate 33 are provided in two groups and are symmetrically arranged at the bottom of the top compartment body 31. The third manganese steel plate 34 is provided in four groups and is symmetrically arranged on the side wall of the top compartment body 31. The square heat-conducting air holes 35 are provided in five groups and are evenly arranged on the surface of the second manganese steel plate 33.

[0025] When in use, the first manganese steel plate 32, the second manganese steel plate 33 and the third manganese steel plate 34 are combined to form a smooth structure on the inner wall of the top compartment body 31;

[0026] The steering exhaust pipe 43 includes an exhaust pipe body 431, a reversing joint 432, and a first air inlet 433. The reversing joint 432 is fixedly connected to one end of the exhaust pipe body 431. The first air inlet 433 is provided at the other end of the exhaust pipe body 431. The transverse main channel steel 42 is provided with a second air inlet corresponding to the reversing joint 432.

[0027] The engine of the truck body 1 is located at the front side of the truck body 1. When used in winter, the high-temperature exhaust gas discharged from the engine exhaust pipe enters the longitudinal main channel steel 41 and the transverse main channel steel 42 through the first air inlet 433 and is heated synchronously. The longitudinal main channel steel 41 and the transverse main channel steel 42 conduct the heat upward to the bottom of the top compartment body 31, thereby heating the cargo inside the top compartment body 31.

[0028] When used in winter, the steering exhaust pipe 43 is rotated so that the reversing joint 432 is connected to the second air inlet, so that the high-temperature exhaust gas can enter the longitudinal main channel steel 41 and the transverse main channel steel 42 through the first air inlet 433. When used in summer, the steering exhaust pipe 43 is rotated downward so that the reversing joint 432 faces the ground, and the high-temperature exhaust gas is directly discharged to the ground without the need to heat the car body.

[0029] Each set of square heat-conducting air holes 35 is welded with a manganese steel plate block;

[0030] During use, gas welding is used to cut square heat-conducting holes 35 on the surface of the second manganese steel plate 33, and the welding gun is inserted into the longitudinal main channel steel 41 at the bottom to cut the internal blockage. In this way, the high-temperature exhaust gas can be exhausted to the tail along the longitudinal main channel steel 41, and the exhaust hole 44 at the tail end of the longitudinal main channel steel 41 is used to discharge the high-temperature exhaust gas to realize air circulation. Similarly, the smoke exhaust hole 45 can discharge the smoke entering the longitudinal main channel steel 41 and the transverse main channel steel 42 to the outside, realizing the circulation of smoke inside the longitudinal main channel steel 41 and the transverse main channel steel 42.
