Description

TECHNICAL FIELD

[0001] The present disclosure belongs to the technical field of engineering machinery, and particularly relates to a mine dump truck auxiliary frame and a mine dump truck. BACKGROUND

[0002] The statements herein merely provide background technology related to the present disclosure, and do not necessarily constitute prior art.

[0003] The mine dump truck is a heavy transport device used in mine operation, and the power system (radiator assembly and power assembly) is the power source of the whole vehicle. A common installation mode is that the radiator assembly is fixed on the main frame, the power assembly (engine and generator) is first fixed to the auxiliary frame offline, and then the auxiliary frame is fixed to the main frame. However, the assembly process is complicated, and when the power system is maintained, the upper platform and cab of the vehicle need to be disassembled, and then the power assembly is lifted from the top, which is inconvenient for maintenance. In addition, the radiator assembly and the power assembly are connected to the main frame through different rubber pads, and the radiator assembly and the power assembly are relatively moved when the power system is running, which causes the problem of interference between the engine fan and the radiator air duct. CONTENT OF THE UTILITY MODEL

[0004] The purpose of the present disclosure is to provide a mine dump truck auxiliary frame and a mine dump truck, which can at least solve one of the above technical problems.

[0005] To achieve the above purpose, one or more embodiments of the present disclosure provide a mine dump truck auxiliary frame, which comprises two frame longitudinal beams arranged in parallel and spaced apart, the frame longitudinal beams are symmetrically arranged and comprise a first bending part, a second bending part and a third bending part; the first bending parts of the frame longitudinal beams are connected by a first cross beam, the second bending parts are connected by a second cross beam, and the third bending parts are connected by a third cross beam.

[0006] Further, the first bending part and the third bending part are arranged in parallel.

[0007] Further, the top surface of the first bending part is provided with a radiator assembly mounting seat.

[0008] Further, the top surface of the third bending part close to the second bending part is provided with an engine mounting seat, and the top surface of the third bending part away from the second bending part is provided with a generator mounting seat.

[0009] Further, the bending angle between the first bending part and the second bending part is equal to the bending angle between the second bending part and the third bending part.

[0010] Further, the engine mounting seat and the generator mounting seat are each provided with a fixing seat connected to the main frame.

[0011] Furthermore, a fixing plate is provided between the engine mounting base and the generator mounting base and the fixed base.

[0012] Furthermore, a pad is also provided on the third bend, and the pad is disposed between the engine mounting base and the generator mounting base.

[0013] Furthermore, a connecting block is provided at the bottom of the longitudinal beam of the frame.

[0014] Another aspect of this disclosure provides a mining dump truck, which includes the mining dump truck subframe described above.

[0015] The beneficial effects of one or more of the above technical solutions are as follows:

[0016] This disclosure effectively avoids the mismatch in damping frequencies between the radiator and engine when the vehicle is in motion, as the radiator assembly, engine, and generator are mounted on the same subframe and then on the main frame. This prevents collisions between the engine fan and the radiator shroud caused by the radiator assembly, engine, and generator being mounted on the same subframe and then on the main frame. Furthermore, it reduces the clearance between the shroud and the fan blades, increases the airflow through the radiator, and improves cooling capacity. Attached Figure Description

Detailed Implementation

[0022] like Figures 1-2 As shown, this embodiment provides a mining dump truck subframe and a mining dump truck, including two parallel and spaced longitudinal beams 1. The longitudinal beams 1 are symmetrically arranged and include a first bending portion 2, a second bending portion 3 and a third bending portion 4.

[0023] Specifically, the first bending part 2 and the third bending part 4 of the frame longitudinal beam 1 are arranged in parallel; the entire auxiliary frame can evenly disperse the pressure when stressed, thereby improving the load-carrying capacity; in addition, the bending angle between the first bending part 2 and the second bending part 3 is equal to the bending angle between the second bending part 3 and the third bending part 4.

[0024] The first bending part 2 of the frame longitudinal beam 1 is connected by the first cross beam 11, the second bending part 3 is connected by the second cross beam 12, and the third bending part 4 is connected by the third cross beam 13, thereby ensuring the stability and load-carrying capacity of the structure and improving the driving stability and safety of the vehicle.

[0025] The top surface of the first bending part 2 is provided with a radiator assembly mounting seat 5, which ensures that the radiator can be stably fixed in place; the top surface of the third bending part 4 near the second bending part 3 is provided with an engine mounting seat 6, so as to reliably fix the engine in place; the top surface away from the second bending part 3 is provided with a generator mounting seat 7, which ensures that the generator can be stably installed in the designated position, and then the radiator assembly and the power assembly (engine + generator) can be installed in the same auxiliary frame and then installed on the main frame, so that the key components can be arranged in the corresponding positions in an orderly manner, thereby ensuring the normal operation and efficient heat dissipation of the entire system.

[0026] At the same time, the radiator and the engine are jointly installed on an auxiliary frame, and a damping pad is arranged between the radiator core and the radiator frame to isolate the vibration of the engine from being transmitted to the radiator.

[0027] At the same time, because the radiator and the engine are jointly installed on an auxiliary frame, a damping pad is specially arranged between the radiator core and the radiator frame to isolate the vibration generated by the engine during operation and prevent the vibration from being transmitted to the radiator, thereby effectively prolonging the service life of the radiator and avoiding unnecessary damage to the radiator.

[0028] As shown in Figure 1 the engine mounting seat 6 and the generator mounting seat 7 are each provided with a fixing seat 9 connected to the main frame. The fixing seat 9 ensures that the auxiliary frame can be firmly fixed on the main frame. A fixing plate 10 is arranged between the engine mounting seat 6 and the generator mounting seat 7 and the fixing seat 9 to enhance the connection strength between the engine mounting seat 6 and the generator mounting seat 7 and the fixing seat 9.

[0029] A pad 8 is arranged between the engine mounting seat 6 and the generator mounting seat 7 on the top surface of the third bending part 4, which can provide additional support for the position where the engine and the generator are connected and can also absorb vibration, thereby ensuring the stability and reliability of the entire system.

[0030] The bottom of the frame longitudinal beam 1 is provided with a connecting block 14 for connecting with a protection plate on a bottom plate to protect the bottom of the bottom shell and the generator.

[0031] The embodiment also provides a mine self-unloading vehicle comprising the mine self-unloading vehicle auxiliary frame.

[0032] The working principle of the utility model is as follows:

[0033] The radiator assembly, the engine and the generator are installed on the same auxiliary frame, and then the auxiliary frame is integrally installed on the main frame. Avoiding the problem that the shock absorbing frequencies of the radiator and the engine are inconsistent because the radiator and the engine are installed on the main frame and the auxiliary frame respectively during the movement of the whole vehicle, the distance between the air guide cover of the radiator and the fan of the engine can be reduced and adjusted through the auxiliary frame, so that the fan can pass through the radiator more smoothly, thereby improving the air volume of the fan passing through the radiator. The engine can be effectively cooled, thereby improving the cooling capacity of the whole cooling system.

[0034] Although the specific embodiments of the present disclosure are described above in combination with the drawings, the present disclosure is not limited to the scope of the specific embodiments, and those skilled in the art should understand that various modifications or changes made on the basis of the technical solutions of the present disclosure without creative labor are still within the protection scope of the present disclosure.
