Description

Technical Field

[0001] This utility model relates to the technical field of mining dump trucks, and in particular to an exhaust conversion device and a mining dump truck. Background Technology

[0002] Mining dump trucks, due to their large load capacity, long continuous working hours, and complex and harsh working environments (such as high altitude, mud, and rugged mountain roads), place extremely high demands on the reliability and functional compatibility of vehicle components. Especially in the frigid northern regions (such as Xinjiang and Inner Mongolia), where winter temperatures often drop below -30°C, the cargo box floor is prone to material freezing due to the lack of a heat source, leading to difficulties in unloading. Therefore, there is a need for cargo box floor heating, requiring both lower exhaust (muffler) and upper exhaust (floor heating) to be considered simultaneously.

[0003] Currently, non-4-engine models require a separate aftertreatment assembly. To achieve upper and lower exhaust functions, the muffler welding assembly and the three-way converter welding assembly need to be replaced frequently, which is cumbersome. Utility Model Content

[0004] This application provides an exhaust conversion device to solve the technical problem of cumbersome operation caused by the need to replace the muffler welding assembly and the three-way converter welding assembly when switching between upper and lower exhaust systems. This application also discloses a mining dump truck that uses the aforementioned exhaust conversion device.

[0005] The first aspect of this application provides an exhaust gas conversion device, comprising:

[0006] The three-way converter welding assembly has port one, port two and port three, wherein port three is connected to the post-processor assembly;

[0007] The first pipe has one end for connection to the port.

[0008] A first connector is used to detachably connect the first pipe to the port.

[0009] The second pipe has one end connected to the cargo box and the other end connected to the second port.

[0010] The second connector is used to detachably connect the second pipe to the second port.

[0011] The shielding member closes port one via the first connector or port two via the second connector.

[0012] The beneficial effects of the above embodiments are as follows: by configuring the first connector and the second connector, it is convenient to connect and disconnect the first pipe, the second pipe and the three-way converter welding assembly respectively. By configuring the shielding component to close the port at the disconnection position, the function of gas upward or downward discharge can be realized. This structure is low in cost and easy to operate.

[0013] Based on the above embodiments, the embodiments of this application can be further improved as follows:

[0014] In one embodiment of this application: the three-way converter welding assembly includes: a housing, a connecting pipe, and a connecting plate. The housing has port one and port three. The connecting pipe is connected to the housing, forming port three. The connecting plate is connected to the top of the housing and is also connected to the upper end of the connecting pipe. The beneficial effect of this step is that the connecting pipe is adapted to the cargo box's warm air inlet, and the connecting plate improves the stability of the connecting pipe connection.

[0015] In one embodiment of this application: the welded assembly of the three-way converter further includes a reinforcing rib; a mounting plate extends upward from the housing, the mounting plate is used for connection with the vehicle frame, and the reinforcing rib is disposed between the mounting plate and the housing. The beneficial effect of this step is that the reinforcing rib improves the structural strength of the welded assembly of the three-way converter.

[0016] The second aspect of this application provides a mining dump truck, including the exhaust conversion device described above. Attached Figure Description

[0026] Example 1

[0027] An exhaust conversion device, such as Figure 1-5 As shown, it includes: a three-way converter welding assembly 1, a first pipe 2, a first connector 3, a second pipe 4, a second connector 5, and a shielding component 6. The three-way converter welding assembly 1 has a first port 101, a second port 102, and a third port 103. The third port 103 is connected to the post-processor assembly 7. One end of the first pipe 2 is used to connect to the first port 101. The first connector 3 is used to detachably connect the first pipe 2 to the first port 101. One end of the second pipe 4 is connected to the cargo box, and the other end is used to connect to the second port 102. The second connector 5 is used to detachably connect the second pipe 4 to the second port 102. The shielding component 6 closes the first port 101 through the first connector 3 or closes the second port 102 through the second connector 5.

[0028] Among them, such as Figure 3As shown, the three-way converter welding assembly 1 includes: a housing 104, a connecting pipe 105, and a connecting plate 106. The housing 104 has the first port 101 and the third port 103. The connecting pipe 105 is connected to the upper end of the housing 104 and forms the third port 103. The connecting plate 106 is connected to the upper part of the housing 104 and is also connected to the upper end of the connecting pipe 105. The connection plate 106 improves the stability of the connection of the connecting pipe 105.

[0029] Among them, such as Figure 3 As shown, the housing 104 has a square structure. The housing 104 is equipped with a port 3 103 facing the after-processor assembly 7. The port 3 103 is fixedly connected to the port extending from the after-processor assembly 7 through a third connector. The side of the housing 104 is equipped with a port 101. The port 101 is connected to the first pipe 2. The other end of the first pipe 2 is directly connected to the atmosphere, which is used to directly discharge the processed gas of the after-processor assembly 7 into the atmosphere. The first pipe 2 is detachably connected to the vehicle frame through a bracket or pipe clamp.

[0030] Among them, such as Figure 3 As shown, the three-way converter welding assembly 1 further includes a reinforcing rib 107. The housing 104 extends upward to form a mounting plate, which is used to connect with the vehicle frame. The reinforcing rib 107 is disposed between the mounting plate and the housing 104, thereby improving the structural strength of the three-way converter welding assembly 1.

[0031] Among them, such as Figure 3 As shown, the mounting plate is bolted to the frame. The connecting plate 106 has a U-shaped bending structure and is connected to the mounting plate. The two sides of the connecting plate 106 are connected to the upper two sides of the connecting tube 105, and the lower end of the connecting tube 105 is connected to the housing 104.

[0032] Among them, such as Figure 1 As shown, the first pipe 2 is made of steel pipe, and the second pipe 4 is made of telescopic flexible pipe.

[0033] Among them, such as Figure 3 , 4 As shown, the shielding component 6 is a cover plate, which is directly placed on the flange of port 101 or port 202, and then fixed together with the flange of the corresponding port 101 or port 202 through the first connector 3 or the second connector 5, thereby sealing port 101 or port 202.

[0034] Among them, such as Figure 5 As shown, the first connecting piece 3, the second connecting piece 5, and the third connecting piece all use clamps. Clamps are easy to install and remove, so they are used in exhaust conversion devices to facilitate operators to switch between upper and lower exhaust.

[0035] When using this exhaust conversion device, for downward exhaust (i.e., the gas processed by the aftertreatment assembly 7 is directly discharged into the atmosphere), disconnect the lower end of the second pipe 4 from port 102, seal port 102 with the shielding piece 6, and connect port 101 to the first pipe 2. For upward exhaust (i.e., transferring the hot gas discharged from the aftertreatment assembly 7 to the cargo box floor for heating), disconnect port 101 from the first pipe 2, remove the shielding piece 6 and install it at port 101, and connect port 102 to the second pipe 4. This exhaust conversion device avoids the cumbersome operation associated with replacing the muffler welding assembly and the three-way converter welding assembly 1, greatly improving the product's ease of use.
