Description

Technical Field

[0001] This utility model relates to the technical field of smelting furnace material feeding carts, specifically a smelting furnace material feeding cart. Background Technology

[0002] After the material is charged into the furnace, it accumulates and piles up inside. A material-shifting cart is needed to move the material to prevent it from piling up and affecting the smelting effect. At the same time, when smelting metal, the material-shifting cart is needed to adjust the material level and furnace conditions to ensure uniform material distribution inside the furnace, expand the reaction zone, eliminate floating material, and break up slag, thereby preventing crusting and surface flames, and keeping the electric furnace in good operating condition.

[0003] When the material feeding car is feeding material, the angle of the forklift frame is adjusted, and the material feeding mechanism is moved up and down by the forklift frame to adjust and move the material feeding mechanism. However, during the stripping process, the material feeding mechanism is restricted by the furnace opening of the smelting furnace, which limits the vertical movement distance of the material feeding mechanism. This makes it impossible to process the material in the furnace deeply, affecting the effects of feeding material, removing floating material and crushing slag. Therefore, a smelting furnace material feeding car is proposed to solve this technical defect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a smelting furnace feeding car.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a smelting furnace material feeding trolley, including a pair of hydraulic push rods on the right side of the forklift body, a mast between the push rods of the hydraulic push rods, the bottom of the mast being hinged to the forklift body, a mounting seat on the mast, and a material feeding rod on the right side of the mounting seat;

[0006] It also includes dialing blocks;

[0007] The right side of the material-pulling rod is connected to an L-shaped connecting rod, and the other end of the L-shaped connecting rod is detachably connected to a telescopic rod, which is detachably connected to the material-pulling block.

[0008] The left end of the lever is provided with a steel wire rope that passes through the telescopic rod, the L-shaped connecting rod and the lever in sequence, and the steel wire rope passes through to the outside of the lever.

[0009] The mounting base is equipped with a winding assembly for winding and unwinding the steel wire rope.

[0010] The above technical solution involves using a forklift to move the mounting base, material-shifting rod, and material-shifting block through the furnace opening, allowing the material-shifting block to rise into the smelting furnace. A hydraulic push rod rotates the gantry to adjust the angle, and the gantry moves the material-shifting block up and down. This adjustment, combined with the forklift's movement, allows the material-shifting block to process the material inside the furnace. To overcome the limitation on the vertical movement distance of the material-shifting block caused by the furnace opening, a winding assembly is used to wind and unwind the steel wire rope. During unwinding, the weight of the material-shifting block and the extension / retraction of the telescopic rod cause the material-shifting block to move downwards, increasing the downward distance and ensuring sufficient material-shifting processing inside the furnace. This improves the effectiveness of material-shifting, eliminating floating material and crushing slag, and ensures efficient material feeding and shifting.

[0011] After the material is moved, the wire rope is wound up, the traction block is reset, and the telescopic rod retracts synchronously.

[0012] As a preferred technical solution of this utility model, the winding assembly includes heat insulation plates symmetrically distributed at the front and rear of the upper end of the mounting base. A drive motor is provided on the surface of the rear heat insulation plate. A rotating shaft that rotates with the surface of the other heat insulation plate is provided at the output shaft of the drive motor. A winding reel is provided concentrically outside the rotating shaft. The other end of the steel wire rope is wound and fixed to the outside of the winding reel.

[0013] Using the above technical solution, the heat insulation plate isolates the heat conduction to the drive motor and the rotating shaft. The drive motor drives the winding reel on the rotating shaft to rotate in both directions, thereby realizing the winding and unwinding of the steel wire rope and ensuring that the steel wire rope pulls the lever block.

[0014] As a preferred embodiment of this utility model, there is a gap between the winding reel and the mounting base, and the size of the gap is smaller than the diameter of the steel wire rope.

[0015] By adopting the above technical solution, it is ensured that the wire rope is prevented from separating from the winding reel when the winding reel is winding and unwinding.

[0016] As a preferred technical solution of this utility model, the telescopic rod is composed of multiple hollow cylinders that are slidably connected to each other. The diameter and inner diameter of the hollow cylinders gradually decrease from top to bottom. The hollow cylinders are not separated from each other. The topmost hollow cylinder and the bottommost hollow cylinder are respectively connected to the L-shaped connecting rod and the lever.

[0017] By adopting the above technical solution, the sliding connection between the hollow cylinders enables the telescopic rod to extend and retract.

[0018] As a preferred technical solution of this utility model, the material feeding rod is detachably provided with a heat insulation seat on the outside, and a magnetic outer cylinder is provided at the lower end of the heat insulation seat. A piston disc slides inside the magnetic outer cylinder. The piston disc is provided with multiple mounting slots on the outside. A stainless steel spring is provided in the mounting slot. An electromagnet block is provided at the other end of the stainless steel spring. The electromagnet block contacts the magnetic outer cylinder. A heat insulation rod is provided on the right side of the piston disc, passing through to the right side of the magnetic outer cylinder. A hinged connecting rod is hinged to the other end of the heat insulation rod and rotates between them.

[0019] As a preferred embodiment of this utility model, when the heat insulation rod is moved to the far right, the telescopic rod is in a fully extended state.

[0020] Using the above technical solution, during the up-and-down movement of the push block and the extension and retraction of the telescopic rod, the extension and retraction of the telescopic rod drives the hinged connecting rod to rotate. When the hinged connecting rod rotates, it drives the piston disc on the heat insulation rod to move inside the magnetic outer cylinder. The extension and retraction of the stainless steel spring ensures that the electromagnet block always fits against the magnetic outer cylinder when the piston disc moves. After the push block movement adjustment is completed, the electromagnet block is energized to attract and fix the magnetic outer cylinder, thereby fixing the push block after movement adjustment and preventing the push block from moving during material feeding.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] 1. This smelting furnace material-dispensing trolley uses a forklift to move the mounting base, dispensing rod, and dispensing block through the furnace opening, allowing the dispensing block to rise into the smelting furnace. A hydraulic push rod rotates the gantry to adjust the angle, and the gantry moves the dispensing block up and down, thus adjusting the movement of the forklift to dispensing material into the furnace. To overcome the limitation on the vertical movement distance of the dispensing block caused by the furnace opening, a winding assembly is used to wind and unwind the steel wire rope. During unwinding, the dispensing block moves downward under its own weight and the extension / retraction of the telescopic rod, increasing the downward distance to ensure sufficient material dispensing within the furnace. This improves the effectiveness of dispensing to remove floating material and crush slag, and ensures efficient material feeding and dispensing.

[0023] 2. In this smelting furnace material feeding car, during the up-and-down movement of the feeding block and the extension and retraction of the telescopic rod, the extension and retraction of the telescopic rod drives the hinged connecting rod to rotate. When the hinged connecting rod rotates, it drives the piston disc on the heat insulation rod to move inside the magnetic outer cylinder. The extension and retraction of the stainless steel spring ensures that the electromagnet block always adheres to the magnetic outer cylinder when the piston disc moves. After the feeding block movement adjustment is completed, the electromagnet block is energized to attract and fix the magnetic outer cylinder, thereby fixing the feeding block after movement adjustment and preventing the feeding block from moving during material feeding.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1 to 4 This embodiment of a smelting furnace material feeding trolley includes a forklift body 1. A pair of hydraulic push rods 2 are hinged and rotated on the right side of the forklift body 1. A mast 3 is hinged between the push rods of the hydraulic push rods 2. The bottom of the mast 3 is hinged to the right side of the forklift body 1. A mounting seat 4 slides on the mast 3. A hydraulic cylinder is mounted on the mast 3. The push rod of the hydraulic cylinder is fixed to the mounting seat 4 and pushes it to move up and down. A feeding rod 5 is fixedly connected to the right side of the mounting seat 4. In addition, a feeding block 6 is also included. An L-shaped connecting rod 7 is connected to the right side of the feeding rod 5. The other end of the L-shaped connecting rod 7 is detachably connected to a telescopic rod 8 by bolts. The telescopic rod 8 and the feeding block 6 are detachably connected by bolts. A steel wire rope 9 is fixed to the left end of the feeding block 6, passing through the telescopic rod 8, the L-shaped connecting rod 7 and the feeding rod 5 in sequence. The steel wire rope 9 passes through to the outside of the upper end of the feeding rod 5. A winding assembly for winding and unwinding the steel wire rope 9 is provided on the mounting seat 4.

[0031] The winding assembly includes heat insulation plates 10 that are symmetrically distributed front and back on the upper surface of the mounting base 4. The heat insulation plates 10 are made of high-temperature resistant heat insulation materials, such as ceramic fiber boards. Their function is to isolate heat conduction to the drive motor 11 and the rotating shaft 12, and protect the equipment from high temperature.

[0032] A drive motor 11 is fixed on the rear surface of the rear heat insulation plate 10. The drive motor 11 is a motor with good high temperature resistance and stable operation, such as a three-phase asynchronous motor. The output shaft of the drive motor 11 is fixed with a rotating shaft 12 that rotates circumferentially with the inner surface of another heat insulation plate 10 through a coupling. The rotating shaft 12 is made of high-strength alloy steel to ensure that it can withstand a large torque.

[0033] A take-up reel 13 is fixed to the outside of the rotating shaft 12 at the same center. There is a gap between the take-up reel 13 and the mounting base 4. The size of the gap is smaller than the diameter of the wire rope 9. This ensures that the wire rope 9 does not separate from the take-up reel 13 when it is winding and unwinding. The other end of the wire rope 9 is wrapped and fixed to the outside of the take-up reel 13. The drive motor 11 drives the take-up reel 13 on the rotating shaft 12 to rotate in both directions, thereby realizing the winding and unwinding of the wire rope 9.

[0034] The telescopic rod 8 is composed of multiple hollow cylinders that slide and connect with each other. In this application, the number of hollow cylinders is not less than four. The hollow cylinders are made of high-strength stainless steel. The diameter and inner diameter of the hollow cylinders gradually decrease from top to bottom, and the hollow cylinders are not separated from each other. The top hollow cylinder and the bottom hollow cylinder are connected to the L-shaped connecting rod 7 and the lever 6, respectively. This structure realizes the telescopic function of the telescopic rod 8.

[0035] The material feeding rod 5 is detachably fixed to a heat insulation seat 14 by bolts. The heat insulation seat 14 is also made of high-temperature resistant heat insulation material, such as ceramic fiber, to reduce the impact of heat on the material feeding rod 5. A magnetic outer cylinder 15 is provided at the lower end of the heat insulation seat 14. The magnetic outer cylinder 15 is made of a magnetic metal material, such as a ferromagnetic alloy.

[0036] A piston disc 16 slides inside the magnetic outer cylinder 15. The diameter of the piston disc 16 is equal to the inner diameter of the magnetic outer cylinder 15. Multiple annularly distributed mounting slots 19 are provided on the outside of the piston disc 16. In this application, the number of mounting slots 19 is not less than three. A stainless steel spring 20 is fixed inside the mounting slot 19. The stainless steel spring 20 has good elasticity and corrosion resistance. An electromagnet block 21 is fixed to the other end of the stainless steel spring 20. The electromagnet block 21 is made of a strong magnetic electromagnet material and is in contact with the magnetic outer cylinder 15.

[0037] A heat insulation rod 17 is fixed to the right side of the piston disc 16, extending through to the outside of the right side of the magnetic outer cylinder 15. The heat insulation rod 17 is made of high-temperature resistant heat insulation material, such as ceramic fiber. The other end of the heat insulation rod 17 is hinged to the telescopic rod 8 with a hinged connecting rod 18. The hinged connecting rod 18 is made of high-strength alloy steel to ensure the stability of its connection. When the heat insulation rod 17 moves to the far right, the telescopic rod 8 is in a fully extended state.

[0038] The control system of this smelting furnace material feeding car mainly consists of a control module, a drive motor control circuit, and an electromagnet control circuit.

[0039] Control Module: The control module adopts a programmable logic controller (PLC), which has powerful logic control capabilities and stability. The control module receives instruction signals from the operator and controls the drive motor 11 and the electromagnet block 21 according to the preset program.

[0040] Drive motor control circuit: The drive motor control circuit is connected to the control module. According to the instructions issued by the control module, it controls the forward and reverse rotation and speed of the drive motor 11. When it is necessary to wind up the wire rope 9, the control module issues an instruction to make the drive motor 11 rotate forward, driving the winding reel 13 to wind up the wire rope 9, and the traction block 6 resets. When it is necessary to release the wire rope 9, the control module issues an instruction to make the drive motor 11 rotate in reverse, releasing the wire rope 9, and causing the block 6 to move down under the action of gravity.

[0041] Electromagnet control circuit: The electromagnet control circuit is also connected to the control module. After the adjustment of the moving block 6 is completed, the control module sends a command to energize the electromagnet block 21. The electromagnet block 21 generates magnetism and attracts and fixes the magnetic outer cylinder 15, thereby fixing the moving block 6 after adjustment and preventing the moving block 6 from moving when feeding materials.

[0042] Specific usage steps,

[0043] Preparation: The operator drives the forklift body 1 to the vicinity of the smelting furnace opening and ensures that the material transfer vehicle is in a stable state.

[0044] Entering the furnace: The forklift body 1 drives the mounting base 4, the material-pulling rod 5 and the material-pulling block 6 to move through the furnace opening, so that the material-pulling block 6 is raised into the smelting furnace.

[0045] Angle and vertical movement adjustment: The hydraulic push rod 2 drives the gantry 3 to rotate and adjust the angle. At the same time, the gantry 3 drives the lever 6 to move up and down and adjust the approximate position of the lever 6 in the furnace.

[0046] Extending the downward movement distance: When it is necessary to extend the downward movement distance of the lever 6, the control module issues a command to reverse the drive motor 11, and the winding assembly loosens the steel wire rope 9. Under the gravity of the lever 6 and the extension and retraction of the telescopic rod 8, the lever 6 moves downward. At the same time, the extension and retraction of the telescopic rod 8 drives the hinged connecting rod 18 to rotate. When the hinged connecting rod 18 rotates, it drives the piston disc 16 on the heat insulation rod 17 to move inside the magnetic outer cylinder 15. The extension and retraction of the stainless steel spring 20 ensures that the electromagnet block 21 always fits against the magnetic outer cylinder 15 when the piston disc 16 moves.

[0047] Fixed position of the toggle block: After the toggle block 6 has been moved and adjusted, the control module sends a command to energize the electromagnet block 21, and the electromagnet block 21 attracts and fixes the magnetic outer cylinder 15, thus fixing the toggle block 6 after it has been moved and adjusted.

[0048] Material feeding: The operator controls the forklift body 1 to move so that the feeding block 6 feeds the material in the furnace, so as to fully eliminate floating material and crush molten slag.

[0049] Reset: After the material feeding is completed, the control module sends a command to make the drive motor 11 rotate forward, the winding assembly winds up the steel wire rope 9, the traction block 6 resets, and the telescopic rod 8 retracts synchronously.

[0050] Beneficial effects

[0051] Extending the material feeding distance: By winding and unwinding the wire rope 9 using the set winding assembly, when unwinding the wire rope 9, the gravity of the shifting block 6 and the telescopic action of the telescopic rod 8 are used to enable the shifting block 6 to move down a greater distance, overcoming the limitation of the furnace mouth on the vertical movement distance of the material feeding mechanism, ensuring that the material in the furnace is fully fed, improving the effect of eliminating floating material and crushing slag, and ensuring the effect of feeding and feeding.

[0052] Fixed position of the toggle block: During the up-and-down movement of the toggle block 6 and the extension and retraction of the telescopic rod 8, the extension and retraction of the telescopic rod 8 drives the hinged connecting rod 18 to rotate, which in turn drives the piston disc 16 on the heat insulation rod 17 to move inside the magnetic outer cylinder 15. The extension and retraction of the stainless steel spring 20 ensures that the electromagnet block 21 always adheres to the magnetic outer cylinder 15 when the piston disc 16 moves. After the toggle block 6 has been moved and adjusted, the electromagnet block 21 is energized to attract and fix the magnetic outer cylinder 15, thus achieving fixation after the toggle block 6 has been moved and adjusting, avoiding the movement of the toggle block 6 during material feeding, and improving the stability and accuracy of material feeding.

[0053] When the stainless steel spring 20 is in the extended state, the electromagnet block 21 is higher than the surface of the piston disc 16, and the electromagnet block 21 and the piston disc 16 are not separated.

[0054] In summary, the material feeding car of this smelting furnace has a reasonable structure and ingenious design, which can effectively solve the problems existing in the current technology and has high practical value and promotion significance.
