Description

Technical Field

[0001] This utility model relates to the field of smelting furnace equipment technology, and in particular to a hydraulic feeding vehicle for smelting furnaces. Background Technology

[0002] In the smelting industry, the addition of recycled materials is a crucial step in the smelting process. Currently, most smelting furnaces commonly use self-unloading tipping vibrating charging carts to add recycled materials. When the charging cart full of recycled materials arrives at the furnace opening, the furnace door first needs to be raised significantly to provide sufficient space for the charging. Then, the self-unloading hopper is tilted up in a jogging motion, and the tilt and vibration of the hopper allow the recycled materials to slowly slide into the smelting furnace. This traditional feeding method has the following drawbacks: 1. The furnace door is raised significantly, causing a large amount of heat to dissipate into the external environment, wasting energy; 2. The vibration of the self-unloading hopper not only causes wear and tear on the hopper itself but also damages the entire smelting furnace frame and other surrounding facilities. Furthermore, the vibration generates significant noise, which can harm the operator's physical and mental health over time; 3. The self-unloading hopper sometimes fails to discharge material and sometimes discharges too much, affecting the feeding process; 4. Because the self-unloading hopper can only discharge material at the furnace opening and cannot directly feed the recycled material into the furnace, the operator must manually push the material deeper into the furnace. This not only increases the operator's workload but also poses a threat to their health in high-temperature environments. The repetitive pushing action can easily lead to operator fatigue and even injury; 5. During the unloading process, recycled material is easily spilled outside the furnace. This spilled material accumulates on the feeding vehicle's tracks or the ground, affecting the vehicle's normal operation and potentially causing wheel jamming and other problems.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

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

[0037] Please see Figures 1 to 12 The diagram illustrates a preferred embodiment of a hydraulic charging vehicle for a smelting furnace. The vehicle includes a frame 2, a traveling mechanism 3, a hopper 4, a tilting plate 5, a pushing mechanism 6, and a drive assembly 7. The traveling mechanism 3 is located at the lower end of the frame 2. The hopper 4 is housed within the frame 2, and the pushing mechanism 6 is located inside the hopper 4. The tilting plate 5 is movably mounted at one end of the hopper 4, and two drive assemblies 7 are located on both sides of the hopper 4. The drive assemblies 7 drive the tilting plate 5 to rotate. In this embodiment, the pushing mechanism 6 uses a linear pushing method to push the recycled material in the hopper 4 into the furnace chamber of the smelting furnace 13. This eliminates the need to open the furnace door of the smelting furnace 13 significantly, preventing severe heat loss. This method, achieved through the cooperation of the pushing mechanism 6 and the tilting plate 5, differs from traditional self-unloading hoppers that rely on vibration and tilting for material feeding. This pushing method allows for precise control of the amount of material fed into the furnace chamber; that is, controlling the extension and retraction of the piston rod of the second cylinder 601 in the pushing mechanism 6 controls the amount of recycled material pushed in. Moreover, the use of the second hydraulic cylinder 601 enables precise control, allowing for the stable and accurate delivery of appropriate amounts of recycled material into the furnace according to the requirements of the smelting process, thus avoiding the problem of unstable material delivery in traditional methods.

[0038] In this embodiment, the flap 5 can rotate under the action of the drive assembly 7. When the flap 5 is flipped up, it can increase the one-time loading capacity of the recycled material, improving the single-time feeding efficiency of the feeding vehicle. Compared with the traditional self-unloading hopper 4, it can transport more recycled material in one loading, reducing the number of round trips of the feeding vehicle and further improving the overall feeding efficiency. When the flap 5 is flipped down, the feeding position of the recycled material in the furnace can be controlled, so that the recycled material can fall more accurately at the required position in the furnace, avoiding the accumulation of recycled material at the furnace opening, which is beneficial to subsequent smelting operations. Moreover, the drive assembly 7 includes a first hydraulic cylinder 701, which can achieve precise control. This precise control of the feeding position helps to optimize the smelting process and improve the smelting effect.

[0039] In this embodiment, the walking mechanism 3 can drive the frame 2 to move horizontally on the guide rail. See [reference needed] Figure 1 As shown, the traveling mechanism 3 at the bottom of the frame 2 contacts the upper end of the guide rail, which can drive the frame 2 to move on the guide rail.

[0040] Furthermore, as a preferred embodiment, the frame 2 includes a chassis 201 and uprights 202 disposed on the upper end of the chassis 201. The hopper 4 is disposed on the upper end of the chassis 201 and located between several uprights 202. In this embodiment, four uprights 202 are provided. The uprights 202 are bolted to the upper end of the chassis 201. The uprights 202 are connected to the first guard plates 8 on both sides of the hopper 4. The uprights 202 and the first guard plates 8 can be welded together or bolted together. The position on the hopper 4 between the two first guard plates 8 is the feeding position. Due to the inclined arrangement of the two first guard plates 8, the recycled material can slide into the interior of the hopper 4 when it comes into contact with the first guard plates 8, preventing the recycled material from spilling out. When adding recycled material into the hopper 4, an appropriate amount of recycled material can be added to prevent the recycled material from exceeding the upper surface of the hopper 4. This prevents the recycled material from spilling out when the pushing mechanism 6 pushes the material.

[0041] In this embodiment, the flap 5 is provided with side plates on both sides to prevent the recycled material from spilling out.

[0042] Furthermore, as a preferred embodiment, it also includes a flap seat 9, a rotating shaft 10, and a connecting shaft 11. Two flap seats 9 are provided on both sides of one end of the hopper 4, and a rotating shaft 10 is provided on one end of the flap 5. The two ends of the rotating shaft 10 are rotatably connected to the two flap seats 9. A connecting shaft 11 is also provided on the flap 5. The flap seats 9 and the hopper 4 can be welded together or bolted together. The flap seats 9 have mounting holes for mounting the rotating shaft 10. The end of the rotating shaft 10 is inserted into the mounting hole and can rotate within the mounting hole. The connecting shaft 11 is welded together with the flap 5. The two ends of the connecting shaft 11 extend outward from the flap 5, and an annular connecting groove is provided on the outer wall of the end of the connecting shaft 11. One end of the steel wire 704 can be installed in the connecting groove through a steel wire 704 clip. For example, one end of the steel wire 704 is wound around the connecting groove once and then fixed by the steel wire 704 clip. Alternatively, one end of the steel wire 704 can be directly welded to the connecting shaft 11.

[0043] Furthermore, as a preferred embodiment, each drive assembly 7 includes a first hydraulic cylinder 701, a wire wheel seat 702, a wire wheel 703, and a wire 704. The first hydraulic cylinder 701 and the wire wheel seat 702 are both located on the side wall of the hopper 4. The wire wheel 703 is rotatably mounted on the wire wheel seat 702. One end of the wire 704 is connected to the connecting shaft 11, and the other end of the wire 704 passes around the wire wheel 703 and is connected to the piston rod of the first hydraulic cylinder 701. The extension and retraction of the piston rod of the first hydraulic cylinder 701 can be precisely controlled. The wire wheel seat 702 is connected to the side wall of the hopper 4 by bolts, while the first hydraulic cylinder 701 is connected to the side wall of the hopper 4 via a cylinder seat, which is bolted to the side wall of the hopper 4. When the piston rod of the first hydraulic cylinder 701 retracts, it pulls the steel wire 704. The steel wire 704 pulls the flap 5 to rotate around the axis of the rotating shaft 10, causing the flap 5 to flip upwards, thus closing one end of the hopper 4. When the piston rod of the first hydraulic cylinder 701 extends, the flap 5 can rotate around the axis of the rotating shaft 10 under its own gravity, causing the material plate to flip down, opening one end of the hopper 4, thus facilitating the recovery of material into the furnace. By controlling the extension and retraction of the piston rod of the first hydraulic cylinder 701, the flipping angle of the flap 5 can be controlled. When the flap 5 flips up, at its maximum angle, the side plates on both sides of the flap 5 will abut against the steel wire wheel seat 702, providing a good limiting effect. A limit block 14 can be set on the flap 5. When the flap 5 flips down to its maximum angle, the limit block 14 will abut against the bottom wall of one end of the hopper 4, providing both limiting and support functions. In this embodiment, a round hole is provided on the piston rod of the first oil cylinder 701. The other end of the steel wire 704 can pass through the round hole and be fixed by the steel wire 704 buckle, or the other end of the steel wire 704 can be directly welded to the piston rod.

[0044] Furthermore, as a preferred embodiment, the pushing mechanism 6 includes a second hydraulic cylinder 601, a pusher plate assembly, and a second guard plate 602. One end of the second hydraulic cylinder 601 is connected to the pusher plate assembly, and the other end of the second hydraulic cylinder 601 is connected to the other end of the hopper 4. The upper end of the pusher plate assembly is provided with the second guard plate 602, and both sides of the second guard plate 602 are in contact with the two first guard plates 8. The pusher plate assembly includes an outer pusher plate 603 and an inner pusher plate 604. The inner pusher plate 604 is located inside the outer pusher plate 603. One end of the second hydraulic cylinder 601 is connected to the inner pusher plate 604. The lower ends of both the inner pusher plate 604 and the outer pusher plate 603 are provided with slots 605. A guide block 12 is provided on the lower inner wall of the hopper 4, and the guide block 12 passes through the slot 605. In this embodiment, two second hydraulic cylinders 601 are provided, arranged side by side. The inner pusher plate 604 and the outer pusher plate 603 are both rectangular. For details, please refer to [reference needed]. Figure 6 As shown, the inner push plate 604 and the outer push plate 603 are welded together. Both ends of the second hydraulic cylinder 601 are connected to the inner push plate 604 and the hopper 4 via flanges. The second guard plate 602 is inclined and cooperates with the two first guard plates 8 to facilitate the entry of recycled material into the hopper 4. The slot 605 cooperates with the guide block 12 to guide the movement of the push plate assembly. The guide block 12 is welded inside the hopper 4.

[0045] Furthermore, as a preferred embodiment, the walking mechanism 3 includes a drive shaft 301, a driven shaft 302, a motor 303, a reducer 304, a drive sprocket 305, a driven sprocket 306, a drive wheel 307, a driven wheel 308, a chain 309, a first bearing seat 310, and a second bearing seat 311. The drive shaft 301 and the driven shaft 302 are mounted on the lower end of the chassis. The two ends of the drive shaft 301 are connected to the chassis 201 through two first bearing seats 310. The two ends of shaft 302 are connected to chassis 201 via two second bearing seats 311. Two drive wheels 307 and one driven sprocket 306 are mounted on drive shaft 301, and two driven wheels 308 are mounted on driven shaft 302. Motor 303 is mounted on chassis 201 and close to drive shaft 301. The output end of motor 303 is connected to reducer 304, and the output end of reducer 304 is equipped with drive sprocket 305. Drive sprocket 305 and driven sprocket 306 are connected by chain 309. The first bearing seat 310 and the second bearing seat 311 are bolted to chassis 201. Reducer 304 is connected to the side wall of chassis 201 via bracket 314, which is bolted to chassis 201. Reducer 304 is also bolted to bracket 314. Drive wheels 307 and driven wheels 308 contact guide rails and can roll on them. Among them, the motor 303 drives the reducer 304 to rotate, the reducer 304 drives the drive sprocket 305 to rotate, the drive sprocket 305 drives the driven sprocket 306 to rotate through the chain 309, and the driven sprocket 306 drives the drive shaft 301 to rotate, which in turn drives the two drive wheels 307 to rotate, providing power for the movement of the frame 2. When the chassis 201 moves, the driven wheel 308 can drive the driven shaft 302 to rotate accordingly.

[0046] Furthermore, as a preferred embodiment, it also includes a reinforcing seat 312 and a third bearing seat 313. Two reinforcing seats 312 are provided at both ends of the chassis 201, and a third bearing seat 313 is respectively provided on each reinforcing seat 312. The drive shaft 301 and the driven shaft 302 are respectively connected to a third bearing seat 313. In this embodiment, the third bearing seat 313 is connected to the reinforcing seat 312 by bolts or direct welding, while the reinforcing seat 312 is connected to the chassis 201 by welding or bolts. The third bearing seat 313 is connected to the middle of the drive shaft 301 or the driven shaft 302, thus providing further support for the drive shaft 301 and the driven shaft 302.

[0047] In this embodiment, see Figure 2 and Figure 3As shown, a hydraulic station 15 is installed on the chassis 201. The hydraulic station 15 is connected to the first cylinder 701 and the second cylinder 601 via a hydraulic valve group, facilitating the provision of power to the first cylinder 701 and the second cylinder 601. An electrical control box 16 is installed on the side wall of the other end of the hopper 4. The electrical control box 16 contains a PLC, and a touch screen can be installed on the outer wall of the electrical control box 16. The PLC is connected to the touch screen or to an external handheld control box. The PLC is also connected to the hydraulic station 15 and the motor 303. Control signals are input through the touch screen or the external handheld control box, enabling the PLC to control the operation of the motor 303 and the hydraulic station 15. The electrical control box 16 is welded to the hopper 4 or bolted to it. The hydraulic station 15 is mounted on the chassis 201 by bolts or welded to the chassis 201.

[0048] The vibration unloading method of the traditional self-unloading hopper 4 is a major cause of equipment wear and noise. In this embodiment, the hydraulic feeding vehicle completely eliminates this vibration unloading method, employing a smooth hydraulic drive and linear pushing mechanism, thus eliminating vibration damage to the smelting furnace 13 frames and other facilities. This not only extends the equipment's service life and reduces maintenance costs but also lowers noise pollution during production, creating a healthier and more comfortable working environment for operators.

[0049] Furthermore, the rear-end pushing mechanism 6 allows for direct feeding of recycled materials into the furnace, eliminating the need for manual operation. This reduces the operator's workload in high-temperature environments, minimizes the risk of injury from prolonged repetitive pushing actions, and protects the operator's health. The operator can complete the feeding process simply by operating an external handheld control box, enhancing both safety and convenience.

[0050] In this embodiment, the feeding control of the recycled material is achieved by controlling the second oil cylinder 601. Each time, an appropriate amount of recycled material can be pushed in, so that the recycled material can accurately enter the furnace and reduce spillage caused by inaccurate feeding. Moreover, the setting of the flap 5 can better guide the recycled material into the furnace, further reducing the possibility of spillage. This ensures the stability of the feeding vehicle operation, avoids the impact of recycled material spillage on the wheel movement, and also reduces the amount of manual cleaning work, keeping the working environment clean.

[0051] In use, control signals are sent to the PLC via a touchscreen or an external handheld control box. The PLC then controls the motor 303 to work, which in turn moves the hydraulic charging cart 1 of the smelting furnace on the guide rail. This moves the hydraulic charging cart 1 of the smelting furnace to the vicinity of the furnace door of the smelting furnace 13, and then opens the furnace door of the smelting furnace 13. The PLC then controls the hydraulic station 15, which in turn controls the first oil cylinder 701 to work. This causes the flap 5 to flip down, so that the flap 5 extends at least partially into the furnace chamber. The PLC then controls the hydraulic station 15, which in turn controls the second oil cylinder 601 to work, ultimately pushing the recycled material into the furnace chamber. The amount of recycled material pushed in is controlled by controlling the extension and retraction of the piston rod of the second oil cylinder 601.

[0052] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
