Description

TECHNICAL FIELD

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

[0002] The statements herein are provided only to complement the background of the present disclosure and are not necessarily prior art.

[0003] The mine dump truck is a heavy-duty transport equipment specially designed for mine operation. With the continuous increase of its tonnage, the power and displacement of the engine also increase. In order to meet the power demand of these large mine dump trucks, many large displacement engines use dual turbocharging technology to improve the air intake efficiency. This dual turbocharging technology usually needs to be used with two air cleaners to ensure that the engine can inhale sufficient air and maintain good working condition. However, the design of this dual turbocharging air intake system often leads to a very complex air inlet pipeline. The complex pipeline is not only difficult to be reasonably laid out, but also occupies more time in the assembly process. This not only increases the production cost, but also may affect the production efficiency of the mine dump truck. CONTENT OF THE UTILITY MODEL

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

[0006] Further, one end of the three-way pipeline connected with the air inlet pipeline is an air inlet end, and one end of the three-way pipeline connected with the turbine chamber air inlets is an air outlet end.

[0007] Further, the turbine chamber air inlets include a turbine chamber first air inlet and a turbine chamber second air inlet, the turbine chamber first air inlet is close to the fan side of the engine, and the turbine chamber second air inlet is away from the fan side of the engine.

[0008] Further, the pipeline part of the three-way pipeline connected with the turbine chamber air inlets is symmetrically arranged, so as to ensure that the air intake resistance in the three-way pipeline and the turbine chamber air inlets is consistent.

[0009] Further, the air inlet pipeline adopts a rubber hose, and the three-way pipeline adopts a rigid pipeline.

[0010] Further, the air filter outlet and the air inlet of the three-way pipeline are connected to the air inlet pipeline through a clamp.

[0011] Further, the air filter outlet and the air inlet of the three-way pipeline are connected to the air inlet pipeline through a clamp.

[0014] Another aspect of the embodiment of the present disclosure provides a mine dump truck, which comprises the mine dump truck air inlet pipeline described above.

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

[0016] The present disclosure uses a symmetrical layout of the three-way pipeline to connect a single air filter with two groups of turbine chamber air inlets on the top of the engine. This ensures that the two turbine chamber air inlets can obtain equal air inlet resistance, and by increasing the flow of the single air filter, the system originally requiring two air filters can now meet the demand with only one air filter, realizing the replacement of the double air filter system. In addition, the connection pipeline using a single air filter is not only shorter in length than the pipeline of a double air filter, but also has a reduced number of interfaces. This not only simplifies the complexity of the system, but also reduces the potential risk of air leakage, thereby improving the reliability and stability of the entire system.

[0021] AsFigure 1 The embodiment shown provides a mine dump truck air inlet pipeline and a mine dump truck.

[0022] The air filter 1 is used for filtering and purifying air, and the side surface is provided with an air filter outlet 5. The top of the engine 2 is provided with two groups of turbine chamber air inlets, the air filter outlet 5 is connected with the turbine chamber air inlets through an air inlet pipeline 3, the air inlet pipeline 3 and the two groups of turbine chamber air inlets are connected through a three-way pipeline 4, and the pipeline length of the air inlet end of the three-way pipeline 4 is less than the pipeline length of the air outlet end of the three-way pipeline 4.

[0023] The turbine chamber air inlets include a turbine chamber first air inlet 6 and a turbine chamber second air inlet 7.

[0024] Specifically, one end of the three-way pipeline 4 connected with the air inlet pipeline 3 is an air inlet end, and one end of the three-way pipeline 4 connected with the turbine chamber air inlets is an air outlet end. The pipeline part of the three-way pipeline 4 connected with the turbine chamber air inlets is symmetrically arranged, so that the air inlet resistance in the three-way pipeline 4 and the turbine chamber air inlets is consistent, and the operation of the whole air inlet system is more smooth and efficient.

[0025] The air inlet pipeline 3 adopts a rubber hose, and the three-way pipeline 4 adopts a rigid pipeline. In terms of connection, double clamps are used to realize the connection between the air inlet pipeline 3 and the air filter outlet 1 and the air inlet of the three-way pipeline 4, so as to ensure the sealing performance of the connection part.

[0026] The air outlet end of the three-way pipeline 4 and the two groups of turbine chamber air inlets are connected through quick connectors. Sealing rings are arranged between the quick connectors and the air outlet end of the three-way pipeline 4 and the two groups of turbine chamber air inlets, so as to ensure the sealing performance of the connection part. The air filter outlet 1 and the air inlet of the three-way pipeline 4 are also provided with sealing rings connected with the air inlet pipeline 3.

[0027] The embodiment also provides a mine dump truck, which comprises the mine dump truck air inlet pipeline.

[0028] The working principle of the utility model is as follows:

[0029] By using the symmetrical layout of three-way pipeline, the single air filter 1 is connected with two groups of turbine chamber air inlet on the top of the engine 2, and the flow of the single air filter 1 is improved, so that the system originally needing two air filters 1 can now meet the demand with only one air filter 1, realizing the replacement of the double air filter system, and the air inlet resistance of the two groups of turbine chamber air inlets on the engine 3 is equal; and the length of the connecting air pipeline 3 using the single air filter 1 is shorter than that of the double air filter pipeline, and the number of interfaces is also reduced, reducing the potential air leakage problem of the pipeline connection.
