[0001] The utility model belongs to the technical field of metallurgical special transport vehicles, and particularly relates to a pure electric transport vehicle. Background Art

[0002] Slag treatment is a crucial component of current smelting technology. There are two main slag cooling methods in China. One is the gantry crane + rail trolley model, where slag ladles are densely arranged, resulting in high land utilization. However, this model suffers from significant drawbacks, such as high track laying costs and difficult maintenance. Few domestic copper smelters use this method and equipment. The other is the use of tank trucks for transportation, where single-row slag ladles are arranged at intervals to leave space for tank trucks to pass through. This method has low land utilization but flexible equipment maintenance.

[0003] With the need for increased smelter capacity and rising land costs, the second method needs to be upgraded. The main approach is to reduce the space reserved for tank trucks and use the reserved space for more slag bags.

[0046] Figure 2 The three-dimensional structure of the transport vehicle of the utility model Figure 2 In the following description, Figure 2As a directional reference, the length direction of the frame 1 is defined as the front-to-back direction, and the driving wheel 10 is located in front of the driven wheel 702; the width direction of the frame 1 is defined as the left-to-right direction, and the power supply system 9 is located on the right side of the front frame; the height direction of the frame 1 is defined as the up-down direction, and the connecting arm 102 is located above the rear support bridge 7.

[0047] like Figure 1-3 As shown, the present application provides a pure electric transport vehicle, including a frame 1 and a power supply system 9. The power supply system 9 is used to provide power support for the transport vehicle to ensure the normal operation of various equipment on the transport vehicle. The frame 1 is an integral structure. Compared with the segmented structure connected by connectors used in the prior art, the integral structure can effectively shorten the length of the transport vehicle. A protective portion 2 is provided on the frame 1. The protective portion 2 divides the frame 1 into a front frame and a rear frame, which is convenient for dividing different functional areas and can avoid the high heat influence of smelting waste slag, thereby forming an effective protection for the driver and various components on the front frame.

[0048] A cab 5 is located atop the front frame. Inside the cab 5 are a steerable seat 501, a first steering wheel 502 located in front of the seat 501, a control console 504 located in front of the seat 501, and a second steering wheel 503 located behind the seat 501. The truck of this application features bidirectional driving. To move forward, the driver faces the first steering wheel 502 and operates it. To move backward, the driver rotates the seat 501 to face the second steering wheel 503 and operates it. To facilitate viewing of the surroundings, the cab 5 has transparent sections on both the front and rear sides. Furthermore, the protective section 2 is provided with a window 202. The transparent section on the front of the cab 5 allows the driver to observe the situation in front of the truck, while the transparent section and window 202 on the rear of the cab 5 allow the driver to observe the rear frame and surroundings, enhancing operational safety and convenience. Specifically, the transparent section is a glass window, and the window 202 is a blind. When the transport truck is driving forward, the shutter is closed; when the transport truck is driving backward, the shutter is opened to provide an effective field of vision for the driver. Those skilled in the art can also replace the window 202 with a glass window according to actual needs.

[0049] Several drive axles are installed at the bottom of the front frame. Each drive axle includes a drive motor and two drive wheels 10 at each end. A power supply system 9 supplies power to the drive motors, which rotate the drive wheels 10, causing the transporter to move. Those skilled in the art can select the number of drive axles installed at the bottom of the front frame based on load requirements. For low-tonnage loads, one drive axle is typically installed per axis, while for high-tonnage loads, two drive axles are typically installed per axis. Drive axles are known in the art and will not be discussed further here.

[0050] like Figure 2 and Figure 4As shown, the rear frame is U-shaped, with a connecting arm 102 at each end for forking the slag pot 11. Each end is hinged to a rear support bridge 7, located below the connecting arm 102. A lifting cylinder 8 is also hinged between the rear frame and each rear support bridge 7. The lifting cylinder 8 is used to drive the connecting arm 102 and the frame 1 up and down. Specifically, the rear support bridge 7 is a driven bridge, which includes a braking device and interconnected lower longitudinal beams 701 and driven wheels 702. It has a large supporting capacity and also meets the braking requirements of the transport vehicle. The driven wheels 702 rotate synchronously with the driving wheels 10, providing a stable driving base for the transport vehicle. The front end of the lower longitudinal beam 701 is hinged to the rear frame, and the rear end is hinged to the lifting cylinder 8. When the lifting cylinder 8 is in operation, the frame 1 can produce a certain angle change relative to the ground to adapt to different working requirements.

[0051] like Figure 4 As shown, the working principle of the utility model is as follows:

[0052] An arc-shaped groove is provided on the connecting arm 102, the front side of the arc-shaped groove extends upward to limit the ear axis of the slag pot 11, and the rear side of the arc-shaped groove is provided with a smooth inclined surface to guide the ear axis of the slag pot 11 to slide into the arc-shaped groove.

[0053] When the transport truck carries the slag pot, the driver operates the second steering wheel 503 and controls the lifting cylinder 8 through the operating console 504 to lower the connecting arm 102 and the rear frame. The angle between the frame 1 and the ground is 6° to 7°, which facilitates the ear axis of the slag pot 11 to enter the arc groove of the connecting arm 102.

[0054] After the tank is carried, the driver controls the lifting cylinder 8 through the operating console 504 to raise the connecting arm 102, so that the frame 1 is parallel to the ground and the slag pot 11 is away from the ground. Then the driver operates the first steering wheel 502, and the transport truck moves forward to start transporting the tank.

[0055] When the transport truck unloads the tank, the driver operates the second steering wheel 503 and controls the lifting cylinder 8 through the operating console 504 to lower the connecting arm 102 and the rear frame. The angle between the frame 1 and the ground is 6° to 7°. The slag pot 11 is placed on the ground, and its ear shaft can be detached from the arc groove of the connecting arm 102.

[0056] like Figure 1-3 As shown, in a specific embodiment of the present invention, the power supply system 9 is arranged on the front frame, which is the existing technology, including batteries, battery thermal management systems, high-voltage junction boxes, controllers, pipelines, frames and other components, and is responsible for providing dynamic power for the entire transport vehicle. It can be isolated from the rear frame under the protection of the protective part 2 to avoid it being affected by the slag pot 11, ensuring that the power supply system 9 can operate stably and efficiently.

[0057] Preferably, the protective portion 2 is an L-shaped sunroof comprising interconnected vertical partitions and a horizontal roof. The vertical partitions divide the vehicle frame 1 into a front frame and a rear frame, with windows 202 provided on the vertical partitions. The horizontal roof has an opening and an upper cover 201 covering the opening. The opening allows the hoisted power supply system 9 to pass through, facilitating installation of the power supply system 9 on the front frame. The upper cover 201 protects the cab and other components below the opening from external factors such as dust and moisture.

[0058] Preferably, a rear guard plate 101 is provided at the bottom of the connection between the front frame and the rear frame, and a lower guard plate 4 is provided at the bottom of the front frame. The rear guard plate 101 and the lower guard plate 4 work together to effectively protect the various components under the front frame from external impacts (such as mud, water, and gravel), scratches, and the influence of harsh environments. This helps to maintain the structural integrity and safety of the frame 1. In addition, a plurality of lights 401 are provided on the lower guard plate 4, and the lights 401 can provide functions such as lighting and warning. Specifically, two lights 401 are provided in the present application. A guardrail 3 and a ladder 6 are also provided on the front frame. The guardrail 3 is used to ensure the safety of operators outside the cab 5 during the operation of the transport vehicle and prevent accidental falls; and the ladder 6 provides a convenient way to get on and off the frame 1.

[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
