Description

Technical Field

[0001] This invention relates to the technical field of smelting production equipment, and more specifically, to an automatic feeding vehicle and its feeding system for a smelting furnace. Background Technology

[0002] In traditional smelting production processes, the weighing of materials often needs to be done separately using other weighing equipment before being added to the charging vehicle, and then the weighed material is transferred to the charging vehicle. However, this method may result in material falling during the transfer process, causing the actual weight of the material added to the charging vehicle to differ from the weight detected by the weighing machine, leading to low accuracy in the detection. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an automatic feeding car and its feeding system for a smelting furnace. The feeding car can directly obtain the weight of the material in the hopper device, thereby ensuring that the actual weight of the material in the hopper device is consistent with the detected weight data, and improving the accuracy of the detected material weight.

[0007] The hopper device is capable of moving up and down in the height direction of the vehicle body, and has a first station and a second station spaced apart in the height direction of the vehicle body; wherein, the hopper device at the first station is detached from the weight detection device, and the hopper device at the second station is placed on the weight detection device.

[0008] A first lifting device is connected between the vehicle body and the hopper device, and the first lifting device is configured to drive the hopper device to lift.

[0009] In some embodiments, the hopper device is vertically connected to the vehicle body;

[0010] The weight detection device is located at the bottom of the hopper device and can be raised and lowered in the height direction of the vehicle body. It has a third station and a fourth station spaced apart in the height direction of the vehicle body. The hopper device at the third station is detached from the weight detection device, and the weight detection device at the fourth station is supported by the hopper device.

[0011] A second lifting device is connected between the weight detection device and the vehicle body, and the second lifting device is configured to drive the weight detection device to lift.

[0012] In some embodiments, the hopper device includes:

[0013] The hopper body is used to load materials; the hopper body includes a first end and a second end disposed opposite to each other, and the first end is provided with a discharge port;

[0014] Mounting bracket, which is capable of being raised and lowered in the height direction of the vehicle body; the first end is rotatably connected to the mounting bracket;

[0015] A drive unit is connected between the hopper body and the mounting frame; the drive unit is configured to drive the hopper body to rotate.

[0016] In some embodiments, the driving device is a telescopic rod, the length of which is changeable; one end of the telescopic rod in its length direction is rotatably connected to the mounting frame, and the other end of the telescopic rod in its length direction is rotatably connected to the second end.

[0017] In some embodiments, the mounting bracket includes:

[0018] Multiple first longitudinal beams are spaced apart in the width direction of the vehicle body;

[0019] Multiple first crossbeams are spaced apart along the length of the vehicle body and connected to multiple first longitudinal beams.

[0020] In some embodiments, there are multiple weight detection devices, and the multiple detection devices form multiple weight detection device groups;

[0021] Multiple weight detection device groups are spaced apart along the length of the vehicle body; each weight detection device group includes at least two weight detection devices, and the at least two weight detection devices are spaced apart along the width of the vehicle body.

[0022] In some embodiments, the vehicle body includes a first portion and a second portion connected sequentially in its length direction; the weight detection device and the hopper device are both disposed in the first portion;

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] The automatic feeding cart 10 for a smelting furnace according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0045] The automatic feeding cart 10 for a smelting furnace according to an embodiment of the present invention includes a cart body 100, a weight detection device 110, and a hopper device 200.

[0046] A weight detection device 110 is disposed on the vehicle body 100. A hopper device 200 is disposed on the vehicle body 100, and at least one of the weight detection device 110 and the hopper device 200 is movable relative to the vehicle body 100. That is, the weight detection device 110 is movable relative to the vehicle body 100; or the hopper device 200 is movable relative to the vehicle body 100.

[0047] The hopper device 200 and the weight detection device 110 are configured to have a feeding state and a weighing state. In the feeding state, the hopper device 200 is detached from the weight detection device 110, and in the weighing state, the hopper device 200 is placed on the weight detection device 110 so that the weight detection device 110 detects the weight of the hopper device 200. Since at least one of the weight detection device 110 and the hopper device 200 is movable relative to the vehicle body 100, the hopper device 200 in the feeding state is detached from the weight detection device 110, and the hopper device 200 corresponds to and is placed on the weight detection device 110.

[0048] The specific implementation process of the automatic feeding vehicle 10 for a smelting furnace according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0049] During material feeding, the feeding cart 10 in this embodiment switches to the feeding state, connecting the hopper device 200 with the weight detection device 110. After the feeding cart 10 is in the feeding state, material is fed into the hopper device 200. After feeding is completed, the feeding cart 10 switches to the weighing state, placing the hopper device 200 on the weight detection device 110 to obtain the weight of the material.

[0050] Compared with related technologies, the automatic feeding cart 10 for a smelting furnace in this embodiment of the invention has a hopper device 200 and a weight detection device 110 mounted on its body 100, and at least one of the weight detection device 110 and the hopper device 200 is movable relative to the body 100. After material is added to the hopper device 200 of the feeding cart 10, the feeding cart 10 can switch to a weighing state to directly obtain the weight of the material in the hopper device 200 using the weight detection device 110, thereby ensuring that the actual weight of the material in the hopper device 200 is consistent with the detected weight data, so that the operator or the feeding control system can adjust the weight of the material in the hopper device 200 according to the detected weight data. Especially when the actual weight of the material in the hopper device 200 is higher or lower than the planned material weight, the operator or the feeding control system can adjust the amount of material in the hopper in a timely manner according to the weight data of the material in the hopper device 200.

[0051] Furthermore, before feeding material into the feeding vehicle 10, the feeding vehicle 10 can switch to the feeding state, so that the hopper device 200 is disengaged from the weight detection device 110. This is to prevent the impact load during feeding from being transmitted to the weight detection device 110 when material is added to the hopper device 200, since the hopper device 200 is not in contact with the weight detection device 110, thus avoiding damage to the weight detection device 110 and ensuring the detection accuracy of the weight detection device 110.

[0052] To make this application easier to understand, the following describes the automatic feeding vehicle 10 for a smelting furnace according to an embodiment of the present invention, taking the length direction of the vehicle body 100 as consistent with the front-to-back direction, the height direction of the vehicle body 100 as consistent with the up-down direction, and the width direction of the vehicle body 100 as consistent with the left-to-right direction.

[0053] In some embodiments, such as Figures 1-4As shown, the hopper device 200 is positioned on top of the weight detection device 110. The hopper device 200 is capable of vertical movement and has a first station and a second station spaced apart vertically. The hopper device 200 at the first station is detached from the weight detection device 110, while the hopper device 200 at the second station is placed on top of the weight detection device 110; that is, the first station of the hopper device 200 is above the second station. When the hopper device 200 is raised to the first station, both the hopper device 200 and the weight detection device 110 are in a feeding state; when the hopper device 200 is raised to the second station, both are in a weighing state. A first lifting device 300 connects the vehicle body 100 and the hopper device 200, and the first lifting device 300 is configured to drive the hopper device 200 to move up and down. The first lifting device 300 is used to move the hopper device 200 between the first and second workstations, thereby enabling the hopper device 200 and the weight detection device 110 to switch between weighing and feeding states. Furthermore, because the hopper device 200 moves vertically, the overall size of the vehicle body 100 is smaller, reducing the floor space and manufacturing costs.

[0054] Specifically, such as Figures 1-4 As shown, the hopper device 200 includes a hopper body 210, a mounting frame 220, and a drive device 230. The hopper body 210 is used to load materials. The hopper body 210 includes a first end 211 and a second end 213 disposed opposite to each other. The first end 211 is provided with a discharge port 212. The mounting frame 220 can be raised and lowered in the height direction of the vehicle body 100. The first end 211 is rotatably connected to the mounting frame 220. The drive device 230 is connected between the hopper body 210 and the mounting frame 220. The drive device 230 is configured to drive the hopper body 210 to rotate. That is, during unloading, the drive device 230 can drive the hopper body 210 to rotate, causing the hopper body 210 to tilt, that is, the discharge port 212 tilts downward, thereby performing the unloading operation.

[0055] Furthermore, a cover plate is also provided at the discharge port 212. The cover plate is opened when discharging material and closed under other operating conditions.

[0056] In some embodiments, such as Figure 1 As shown, the drive device 230 is a telescopic rod with a variable length. One end of the telescopic rod is rotatably connected to the mounting frame 220 along its length, and the other end is rotatably connected to the second end 213. Thus, the extension and contraction of the telescopic rod drives the hopper body 210 to rotate. The structure is simple and the manufacturing cost is low.

[0057] Alternatively, the telescopic rod can be a hydraulic cylinder.

[0058] In some embodiments, such as Figure 7 As shown, the mounting frame 220 includes multiple first longitudinal beams 221 and multiple first transverse beams 222. The multiple first longitudinal beams 221 are spaced apart in the width direction of the vehicle body 100, and the multiple first transverse beams 222 are spaced apart in the length direction of the vehicle body 100 and connected to the multiple first longitudinal beams 221. In other words, the mounting frame 220 is a frame structure, which ensures high structural stability of the mounting frame 220 while also reducing its weight, thereby reducing the load on the power unit of the feeding vehicle 10 in this embodiment and saving energy and operating costs.

[0059] In other embodiments, the hopper device 200 is vertically connected to the vehicle body 100, the weight detection device 110 is located at the bottom of the hopper device 200, and the weight detection device 110 is vertically movable in the height direction of the vehicle body 100, and has a third station and a fourth station spaced apart in the height direction of the vehicle body 100. The hopper device 200 at the third station is detached from the weight detection device 110, while the weight detection device 110 at the fourth station is supported by the hopper device 200. A second lifting device (not shown) is connected between the weight detection device 110 and the vehicle body 100, and the second lifting device is configured to drive the weight detection device 110 to move up and down.

[0060] In other words, when the weight detection device 110 is raised to the third position, the hopper device 200 and the weight detection device 110 are in the feeding state; when the weight detection device 110 is raised to the fourth position, the hopper device 200 and the weight detection device 110 are in the weighing state. Thus, the second lifting device is used to move the hopper device 200 up and down between the third and fourth positions, thereby realizing the switching between the weighing state and the feeding state of the hopper device 200 and the weight detection device 110.

[0061] Optionally, the second lifting device can be a hydraulic cylinder, with the extension and retraction direction of the hydraulic cylinder being consistent with the up and down direction. The weight detection device 110 is mounted on the hydraulic cylinder so that the hydraulic cylinder drives the weight detection device 110 to move up and down.

[0062] In some embodiments, such as Figure 5As shown, there are multiple weight detection devices 110, forming multiple groups of weight detection devices 110. These groups are spaced apart in the front-to-back direction; each group includes at least two weight detection devices 110, which are spaced apart in the left-to-right direction. In other words, by evenly distributing the multiple weight detection devices 110 on the vehicle body 100, they can simultaneously detect the material in the hopper device 200. This not only ensures the accuracy of the detection data but also, if the data detected by one of the multiple weight detection devices 110 differs significantly from the data detected by the other weight detection devices 110, that weight detection device 110 may be malfunctioning, facilitating timely troubleshooting by operators or the control system.

[0063] Optionally, the weight detection device 110 can be a pressure sensor.

[0064] In some embodiments, such as Figure 1 and Figure 2 As shown, the vehicle body 100 includes a first part 201 and a second part 202 connected sequentially in the front-to-back direction. A weight detection device 110 and a hopper device 200 are both disposed on the weight detection device 110, and a counterweight structure 120 is disposed on the second part 202. It is understood that, since the material loaded in the hopper device 200 is relatively heavy, in order to improve the stability of the feeding vehicle 10 in this embodiment during operation, the hopper device 200 and the counterweight structure 120 are respectively disposed on the first part 201 and the second part 202 to make the weight of the feeding vehicle 10 more even.

[0065] In some embodiments, such as Figure 1 and Figure 5 As shown, the vehicle body 100 includes a first support rib 130, a second support rib 140, and a plurality of second crossbeams 150. The second support ribs 140 and the first support ribs 130 are spaced apart in the left-right direction of the vehicle body 100, and the plurality of second crossbeams 150 connect the first support ribs 130 and the second support ribs 140. This design ensures high structural strength of the vehicle body 100 while reducing structural redundancy, lowering its weight, and reducing manufacturing costs.

[0066] Furthermore, such as Figures 3-5As shown, the portion of the first support rib 130 corresponding to the first part 201 is the first support segment 131. The dimension of the first support segment 131 in the vertical direction decreases in the direction away from the second part 202, that is, the height of the first support segment 131 gradually decreases in the forward direction. This forms a stable triangular structure at the front of the vehicle body 100, improving the stability of the vehicle body 100 and reducing structural redundancy and the overall weight of the vehicle body 100. Similarly, the portion of the second support rib 140 corresponding to the first part 201 is the second support segment 141. The dimension of the second support segment 141 in the vertical direction decreases in the direction away from the second part 202, also improving the stability of the vehicle body 100 and reducing structural redundancy and the overall weight of the vehicle body 100.

[0067] In some embodiments, such as Figure 5 and Figure 6 As shown, the automatic feeding cart 10 for a smelting furnace in this embodiment of the invention further includes a drive assembly 400, which provides power to the feeding cart 10 and is disposed in the second part 202. Thus, the hopper device 200 is disposed in the first part 201, and the drive assembly 400 and counterweight structure 120 are disposed in the second part 202, to further improve the weight uniformity of the feeding cart 10, thereby giving the feeding cart 10 of this embodiment better operational stability.

[0068] In some embodiments, such as Figure 5 and Figure 6 As shown, the drive assembly 400 includes a motor 410, a reducer 420, a drive wheel assembly 430, and a universal coupling 440. The reducer 420 is coupled to the output end of the motor 410. The drive wheel assembly 430 includes a drive wheel body 431 and a rotating shaft 432 for driving the drive wheel body 431 to rotate. The rotating shaft 432 is connected to the drive wheel. The universal coupling 440 is connected between the output shaft of the reducer 420 and the rotating shaft 432. That is, through the cooperation of the reducer 420 and the motor 410, the motor 410 drives the output shaft of the reducer 420 to rotate. The output shaft of the reducer 420 then sequentially drives the universal coupling 440, the rotating shaft 432, and the drive wheel body 431 to rotate, thereby causing the drive wheel body 431 to move the feeding cart 10 in this embodiment.

[0069] In the automatic feeding cart 10 for smelting furnace of this embodiment, the output shaft of the reducer 420 is connected to the rotating shaft 432 of the drive wheel through a universal coupling 440. The universal coupling 440 compensates for the error caused by the misalignment of the center lines of the output shaft of the reducer 420 and the input shaft of the drive wheel, thereby preventing damage to the reducer 420 and extending its service life. Therefore, it ensures that the feeding cart 10 of this embodiment can operate normally and continuously.

[0070] Furthermore, such as Figure 5 and Figure 6 As shown, the drive assembly 400 also includes a torque limiter 450, which is connected between the universal coupling 440 and the shaft 432. The additional connection of the torque limiter 450 between the universal coupling 440 and the shaft 432 allows for the limitation of external input torque, preventing excessive torque and protecting the maximum input torque of the reducer 420.

[0071] In some embodiments, the output end of the motor 410 is connected to the input end of the reducer 420 via a belt, so that the power output by the motor 410 is transmitted to the reducer 420 by means of the belt.

[0072] In some embodiments, such as Figures 1-2 As shown, the counterweight structure 120 is a cover, and it is disposed on top of the drive assembly 400. Therefore, the counterweight structure 120 not only optimizes the weight distribution in this embodiment, but also serves as a shell structure covering the drive assembly 400, providing protection for it.

[0073] Specifically, the counterweight structure 120 includes a top plate, a first side plate, and a second side plate. The first side plate and the second side plate are spaced apart in the left-right direction, and the tops of the first side plate and the second side plate are connected to the top plate.

[0074] Optionally, the counterweight structure 120 is made of iron.

[0075] In some embodiments, such as Figure 7 As shown, a buffer device 223 is provided on the mounting frame 220, and the buffer device 223 is located between the mounting frame 220 and the hopper body 210. That is, the automatic feeding cart 10 for a smelting furnace in this embodiment of the invention is provided with a mounting frame 220, and a rotatable hopper body 210 is provided on the mounting frame 220. When the hopper body 210 rotates, it tilts, allowing material to be discharged from the discharge port 212 of the hopper body 210. Furthermore, the buffer device 223 is provided on the mounting frame 220, and is located between the mounting frame 220 and the hopper body 210. Therefore, when material is added to the hopper body 210, the buffer device 223 can buffer the impact load generated by material falling into the hopper body 210, preventing the impact load from directly acting on the cart body 100, thereby extending the service life of the cart body 100.

[0076] Specifically, there are multiple buffer devices 223, forming multiple groups of buffer devices 223. These groups of buffer devices 223 are spaced apart in the front-rear direction. Each buffer device 223 includes at least two buffer devices 223, which are spaced apart in the left-right direction. This ensures that the multiple buffer devices 223 are evenly distributed on the mounting bracket 220, allowing them to evenly buffer the vehicle body 100.

[0077] In some embodiments, the buffer device 223 is a buffer airbag, which can buffer the vehicle body 100. It has a simple structure and low manufacturing cost.

[0078] The feeding system of this invention includes a feeding module and a feeding cart 10, the feeding module having a discharge port. The feeding cart 10 is any of the feeding carts described above, and the discharge device of the feeding cart 10 corresponds to the discharge port.

[0079] The feeding system of this invention includes a feeding vehicle 10 with a hopper device 200 and a weight detection device 110 mounted on its body 100. At least one of the weight detection device 110 and the hopper device 200 is movable relative to the body 100. After material is added to the hopper device 200 of the feeding vehicle 10, the feeding vehicle 10 can switch to a weighing state to directly obtain the weight of the material in the hopper device 200 using the weight detection device 110. This ensures that the actual weight of the material in the hopper device 200 matches the detected weight data, allowing the operator or the feeding control system to adjust the weight of the material in the hopper device 200 based on the detected weight data. Especially when the actual weight of the material in the hopper device 200 is higher or lower than the planned material weight, the operator or the feeding control system can promptly adjust the amount of material in the hopper based on the weight data.

[0080] Furthermore, before feeding material into the feeding vehicle 10, the feeding vehicle 10 can switch to the feeding state, so that the hopper device 200 is disengaged from the weight detection device 110. This is to prevent the impact load during feeding from being transmitted to the weight detection device 110 when material is added to the hopper device 200, since the hopper device 200 is not in contact with the weight detection device 110, thus avoiding damage to the weight detection device 110 and ensuring the detection accuracy of the weight detection device 110.

[0081] In some embodiments, the feeding module can be a feeding hopper, a metallurgical crane, a belt conveyor, or other feeding equipment.

[0082] In some embodiments, the feeding cart 10 is equipped with a distance measuring module, which is used to detect the distance between the discharge port and the feeding module. This allows the operator or control system to determine whether the feeding cart 10 has moved into position based on the distance data detected by the distance measuring module.

[0083] Alternatively, the ranging module can be a laser ranging sensor, an ultrasonic ranging sensor, or other types of ranging sensors.

[0084] The automatic feeding car 10 for a smelting furnace and its feeding system provided by the present invention have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
