Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical special transport vehicles, in particular to a pure electric unmanned slag transport vehicle. Background Art

[0002] As one of the nation's pillar industries, the development of the metallurgical industry is directly linked to the nation's economic strength and industrial level. The large amount of residual slag produced during the smelting process is discharged from the smelting furnace. Slag tanks are required to transport the steel and copper slag to slag yards or processing plants for subsequent comprehensive recycling and reuse. The transportation and processing of steel and copper slag is a crucial step in this process.

[0003] With the continuous development of transportation vehicle technology and the country's requirements for metallurgical enterprises to advocate "carbon peak and carbon neutrality", tank trucks in trackless transportation have become the main transportation equipment for domestic metallurgical slag transportation. However, with the advancement of science and technology and the rise of intelligent manufacturing, traditional tank trucks have many integrated functions, complex structures, and require human drivers. They can no longer meet the high efficiency and high quality needs of modern metallurgical enterprises. For the metallurgical industry, the copper slag field is relatively closed and easier to implement unmanned operation. Against this technical background, copper smelting enterprises proposed to establish a smart slag field, which includes the realization of unmanned metallurgical slag transportation methods. However, the relevant technologies for unmanned metallurgical slag transportation are not mature enough at this stage, and some technologies still need to be verified in practice. For example, China's invention patent application CN 117681987 A discloses an unmanned slag pot transporter, in which a lifting cylinder is installed at the rear end of the frame. When the lifting cylinder is shortened, the height of the rear end of the frame is lowered, so that the slag pot seat at the rear end of the frame moves horizontally to below the slag pot ear axis; when the lifting cylinder is extended, the height of the rear end of the frame is increased, so that the slag pot seat lifts the slag pot off the ground, and cooperates with the horizontal movement of the frame to realize unmanned carrying, transporting and unloading of the slag pot. However, the lifting cylinder is located at the rear end of the frame, which increases the length of the entire vehicle, and there is a lack of protection measures for the external cylinder. The force application positions of the slag pot and the lifting cylinder on the frame are offset, which makes the force state of the frame unreasonable. Utility Model Content

[0008] In one embodiment, slag pot trunnions are provided on both sides of the slag pot, and the slag pot supporting portion on the bearing seat is a U-shaped groove with an upward opening for accommodating the slag pot trunnions.

[0009] Preferably, the bottom of the U-shaped groove is arc-shaped, and the front and rear sides of the U-shaped groove are respectively a front stop and a rear stop.

[0010] Furthermore, when the oil cylinder contracts and drives the rear end of the side arm to tilt downward, the rear stop is lower than the bottom edge of the slag pot ear axis, and the front stop is higher than the axis of the slag pot ear axis.

[0011] In one embodiment, a contact sensor is provided in the slag pot support portion, and the contact sensor is connected to the electronic control system.

[0014] In one embodiment, escalators are provided on both sides of the front end of the frame.

[0015] The utility model has the following beneficial effects: in the pure electric unmanned slag transport vehicle of the utility model, the oil cylinder connected between the rear end of the side arm and the middle part of the lower longitudinal beam is located on the outside of the bearing seat and is hinged at the bottom of the side arm. Therefore, compared with the prior art, the pure electric unmanned slag transport vehicle of the utility model is shorter in length, has a compact overall structure, light weight and low manufacturing cost; the side arm and the bearing seat isolate the oil cylinder from the slag pot, which can protect the oil cylinder; and the hinge point of the oil cylinder on the side arm is located directly below the slag pot support part, and the oil cylinder supports the frame directly below the slag pot, which can offset the forces exerted on the frame by the two.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0042] In addition, in the description of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0043] like Figure 1 The utility model provides a pure electric unmanned slag transport vehicle for transporting slag tanks 7, including a vehicle frame 1 and a hood 8 fixed above the vehicle frame 1, the hood 8 is provided with a heat dissipation structure, the vehicle frame 1 is provided with a motor, a battery and an electronic control system, and the motor, battery and electronic control system are arranged in the hood 8, escalators 9 are provided on both sides of the front end of the vehicle frame 1, and also includes a vehicle body radar and a camera (not shown in the figure) connected to the electronic control system to realize unmanned driving to complete the tank transportation and loading and unloading functions. The pure electric unmanned slag transport vehicle also includes a front axle 2 and two rear axles 3, wherein the front axle 2 is connected to the bottom of the front end of the vehicle frame 1, serving as the drive axle of the slag transport vehicle, and is connected to the steering system; the rear end of the vehicle frame 1 includes two side arms 11 located on the left and right sides of the slag transport vehicle, and a accommodating groove 113 with an opening facing backward is formed between the two side arms 11 (see Figure 2 ), used to place the slag pot 7. A first hinge seat 111 is provided at the bottom front end of each side arm 11. The first hinge seat 111 is hinged to the front end of a lower longitudinal beam 5, and the rear end of the lower longitudinal beam 5 is connected to a rear axle 3. A cylinder 6 is connected between the rear end of the side arm 11 and the middle part of the lower longitudinal beam 5. The cylinder 6 is in a basically vertical state. Specifically, a second hinge seat 112 is provided at the bottom rear end of the side arm 11. The upper end of the cylinder 6 is hinged to the second hinge seat 112, and the lower end of the cylinder 6 is hinged to the middle part of the lower longitudinal beam 5. When the cylinder 6 is extended or retracted, it can drive the rear ends of the two side arms 11 to tilt downward or lift upward at the same time, realizing the function of carrying and unloading the pot.

[0044] Furthermore, if Figure 3 and Figure 4 , slag pot ear shafts 71 are provided on both sides of the slag pot 7, and a bearing seat 4 is provided at the rear end of the two side arms 11. A slag pot support part 41 is provided on the bearing seat 4 to support the slag pot 7. The oil cylinder 6 is located on the outside of the bearing seat 4 and is hinged to the bottom of the side arm 11, that is, the oil cylinder 6 is located in a semi-enclosed space formed by the bearing seat 4 and the rear end of the side arm 11 of the slag transport vehicle, which plays a certain protective role for the oil cylinder 6. At the same time, the hinge point 114 of the oil cylinder 6 on the side arm 11 is located just below the slag pot support part 41. This arrangement makes the forces exerted by the slag pot 7 and the oil cylinder 6 on the frame 1 offset each other at the same position, which can reduce the design requirements for the bearing strength of the frame 1. It can also make the overall structure of the slag transport vehicle more compact and lighter in weight; the slag pot support portion 41 on the bearing seat 4 is a U-shaped groove with an opening upward for accommodating the slag pot ear shaft 71, and the bottom of the U-shaped groove is arc-shaped. The front and rear sides of the U-shaped groove are respectively a front stop 42 and a rear stop 43. A contact sensor is provided on the inner surface of the front stop 42 of the slag pot support portion 41, and the contact sensor is connected to the electronic control system. When the oil cylinder 6 contracts and drives the rear end of the side arm 11 to tilt downward, the rear stop 43 is lower than the bottom edge of the slag pot ear shaft 71, and at the same time, the front stop 42 is higher than the axis of the slag pot ear shaft 71, so that the slag pot ear shaft 71 can smoothly enter the slag pot support portion 41 when reversing.

[0045] The present invention is further described below with reference to a specific embodiment:

[0046] like Figure 1The frame 1 of the slag truck of the present invention serves as the main skeleton of the slag truck, bearing weight and connecting components above and below the frame 1. A motor, battery, and electronic control system are installed above the front end of the frame 1. The motor provides the power source for the oil cylinder 6, steering system, brakes, etc., and the battery provides electricity for the entire slag truck, which is green and environmentally friendly. The electronic control system controls the operating status of the entire vehicle. The body radar and camera connected to the electronic control system assist in realizing the pure electric drive of the slag truck and unmanned tank transportation, loading, and unloading. For example, millimeter-wave radars are installed on both sides of the slag truck body to detect obstacles on both sides, promptly detecting and preventing collisions between the two sides. A laser radar and millimeter-wave radar are installed in the front of the slag truck body to detect obstacles in front, and a camera is installed to provide vision and assist in identification to ensure the stable and safe operation of the slag truck.

[0047] like Figures 1 to 3 The hood 8 is fixed above the frame 1, and heat dissipation holes are provided on the outer wall of the hood 8 for sufficient heat dissipation of electrical components such as the motor, battery and electronic control system inside it. At the same time, the hood 8 also plays a role in protecting the motor, battery and electronic control system; an escalator 9 is arranged on each side of the left and right sides of the front of the frame 1 of the slag truck, which can facilitate maintenance personnel to repair parts on the slag truck; the front axle 2 serves as the drive axle of the slag truck and is connected to the steering system of the slag truck, and the front axle 2 can be arranged in different quantities according to the load requirements. For example, one drive axle is generally chosen for small tonnage loads, and two drive axles are coaxially arranged for large tonnage loads. At the same time, a corresponding steering system is selected according to the number of drive axles.

[0048] like Figure 4 When the pure electric unmanned slag transport vehicle of the present invention carries the slag pot 7, the slag pot 7 is placed on the ground in advance, and the slag transport vehicle reverses and approaches the slag pot 7. The camera at the rear of the slag transport vehicle assists in identifying the situation behind the slag transport vehicle. When the body radar at the rear of the slag transport vehicle detects that there is a certain distance between the supporting seat 4 and the slag pot 7 to be transported, the electronic control system controls the oil cylinder 6 to retract, driving the rear end of the side arm 11 to tilt downward until the inclination angle of the side arm 11 reaches the set value, and controls the oil cylinder 6 to stop retracting. At this time, the rear stopper 43 of the supporting seat 4 is lower than the bottom edge of the slag pot ear shaft 71. The slag transport vehicle continues to reverse, and the slag pot 7 smoothly enters the accommodating groove 113 between the two side arms 11, and the slag pot ear shaft When the slag pot 71 reaches above the slag pot support 41, the slag pot trunnion 71 will not pass over the front stop 42 because the front stop 42 is higher than the axis of the slag pot trunnion 71. When the slag pot trunnion 71 contacts the contact sensor provided on the inner surface of the front stop 42, the contact sensor transmits a signal to the electronic control system, which in turn transmits a signal to the control valve of the oil cylinder 6, causing the oil cylinder 6 to extend and lift the rear ends of the two side arms 11 of the slag transport vehicle to a horizontal position, thereby lifting the slag pot 7 off the ground. At this time, the slag pot trunnion 71 is located in the slag pot support 41, completing the slag pot carrying. The slag transport vehicle then transports the slag pot 7.

[0049] Upon reaching the transfer destination and stopping, when the slag tank needs to be unloaded, the oil cylinder 6 retracts, driving the rear end of the side arm 11 to tilt downward. After the bottom of the slag tank 7 touches the ground, the oil cylinder 6 further retracts to lower the rear stop 43 below the bottom edge of the slag tank trunnion 71. The slag tank 7 is then started forward, and the slag tank 7 is smoothly lowered to the ground. The slag tank 7 is then driven away, and the unloading is completed. The oil cylinder 6 then extends, restoring the vehicle frame 1 to a horizontal state.

[0050] Combine Figure 3 and Figure 4 The cam 71 of the present invention is fixed on the support frame 11, and the support frame 11 is provided with an upper end portion 72 of the support frame 11, so that the cam 71 of the present invention can be fixed on the support frame 11, and the support frame 11 is provided with an upper end portion 72 of the support frame 11.

[0051] 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.
