Description

Technical Field

[0001] The utility model relates to the technical field of bottom plates of dump trucks, in particular to a bottom plate heating structure of a wide-body dump truck. Background Art

[0002] With the increasing size of mining machinery, the demand for wide-body dump trucks is growing in mining areas, particularly open-pit mines. As excavator tonnage continues to increase, their bucket capacity is also increasing. Bucket widths have now surpassed those of standard dump trucks, significantly impacting operational efficiency in mining areas. Therefore, widening dump trucks has become the simplest and most effective way to address these requirements. Currently, wide-body dump trucks have reached a width of 3 meters, allowing the excavator bucket to easily load slag, earth, and rock into the cargo compartment, significantly improving mining efficiency and equipment usability.

[0003] Currently, most wide-body dump trucks sold in northern China utilize exhaust gas recirculation heating technology. This technology channels a portion of the engine's exhaust gas through the cargo box floor, where it is heated before being discharged from the rear of the vehicle, making it beneficial for operations in colder northern regions. However, the exhaust gas currently flows from both sides of the cargo box floor toward the center, where it is then discharged from the center longitudinal beam to the rear. This setup requires exhaust to be accessible through all crossbeams below the desired heating zone, increasing the requirements for cargo box manufacturing and making the floor difficult to fabricate. Utility Model Content

[0004] In view of the defects in the prior art, the utility model provides a floor heating structure for a wide-body dump truck to solve the problem that the current cargo box heating by exhaust gas circulation has high requirements on the cargo box manufacturing process and the floor processing is difficult.

[0005] The utility model provides a wide-body dump truck bottom plate heating structure, comprising:

[0006] base plate;

[0007] A longitudinal beam is arranged at intervals on the bottom of the base plate, and a first conducting hole is opened at the front end of the longitudinal beam;

[0008] A front beam is provided at the bottom of the base plate, and the front beam is connected to the first conducting hole;

[0009] Cross beams are arranged at intervals on the bottom of the base plate, and the cross beams and the longitudinal beams are arranged crosswise;

[0011] The rear beam is arranged at the bottom of the base plate, the rear ends of the rear beam and the longitudinal beam are communicated, and exhaust ports are arranged at intervals on the rear beam.

[0012] It can be seen from the above technical solution that the utility model provides a wide-body dump truck floor heating structure, which is connected to the exhaust gas through the air intake, and then the exhaust gas is connected to multiple longitudinal beams from the front beam to achieve floor heating, and finally discharged from the exhaust port on the rear beam. The exhaust gas is directly guided out through the longitudinal beam from the front end to the rear end of the floor, which improves the heating efficiency and reduces the difficulty of floor processing.

[0013] Optionally, a plurality of second conducting holes communicating with the longitudinal beams are provided on the rear beam.

[0014] Optionally, the exhaust port includes a first exhaust port and a second exhaust port, wherein the first exhaust port is arranged at the midpoint of the rear beam, and the second exhaust port is symmetrically arranged at both ends of the rear beam. The first exhaust port and the second exhaust port are arranged in a balanced manner to ensure balanced exhaust of the rear beam.

[0015] Optionally, both ends of the rear beam are provided with cover plates, the cover plates are tilted, and the second exhaust port is provided on the cover plates. The second exhaust port facilitates exhaust gas to be discharged from both sides of the vehicle.

[0016] Optionally, the crossbeam and the longitudinal beam are arranged perpendicularly, and triangular reinforcement ribs are provided between the crossbeam and the longitudinal beam, with the triangular reinforcement ribs provided at the intersection of the crossbeam and the longitudinal beam. The perpendicular arrangement of the crossbeam and the longitudinal beam can enhance the bonding strength between the two beams, and the triangular reinforcement ribs further enhance the structural strength, thereby increasing the load-bearing capacity of the dump truck.

[0017] Optionally, there are an odd number of longitudinal beams, one of which connects the midpoint of the front beam and the rear beam, and the remaining longitudinal beams are symmetrically arranged based on the line connecting the midpoints of the front beam and the rear beam, thereby ensuring balanced heating on both sides of the bottom plate.

[0018] Optionally, the connecting plate is arranged between two adjacent longitudinal beams located on the outside. The connecting plate is arranged between two adjacent longitudinal beams located on the outside to facilitate the exhaust port to communicate with the exhaust gas.

[0019] By adopting the above technical solution, this application has the following technical effects:

[0020] The utility model provides a floor heating structure for a wide-body dump truck. The exhaust gas is introduced through an air inlet, and then the exhaust gas is connected to multiple longitudinal beams from the front beam to achieve floor heating. Finally, the exhaust gas is discharged from the exhaust port on the rear beam. The exhaust gas is directly guided through the longitudinal beams from the front end to the rear end of the floor, thereby improving the heating efficiency and reducing the difficulty of floor processing.
