Description

Technical Field

[0001] The invention relates to the technical field of metallurgical casting, and in particular to an anti-skid lifting device for metallurgical casting. Background Art

[0002] Metallurgical casting is an important branch of metal processing. In the metallurgical casting industry, metal materials are extracted from ores and processed into components of various shapes and sizes, among which lifting devices play a vital role. In the metallurgical casting process, lifting devices are used more frequently. Raw materials such as ore, scrap steel, coke, limestone, etc. need to be lifted into blast furnaces, converters or other smelting equipment for processing. When the cast blanks or preliminarily processed parts are completed, they need to be lifted and transferred to the next processing link or storage area. When lifting heavy objects, the lifting device is prone to slipping due to the influence of the gravity of the material, making it difficult to lift the heavy objects. Therefore, anti-skid is one of the key technologies to ensure production safety and efficiency.

[0003] In the existing patent CN213833273U, an anti-skid bucket elevator for metallurgical casting is involved, including a base, a universal wheel, and a drive motor; the universal wheel is installed on the bottom of the base by threaded connection, and the drive motor is fixedly installed on the top of the base by bolts; the bracket is installed on both sides above the base, and the bottom of the bracket is connected to the base by welding; the column is installed between the bracket and the base, and the bottom of the column is connected to the base by welding, and the top of the column is connected to the bracket by welding; the application improves the anti-skid bucket elevator for metallurgical casting, with reasonable structural design, strong wrapping, small gaps between friction plates, increased contact area with the conveyor belt, increased friction, improved anti-skid effect, convenient installation and disassembly, and easy replacement.

DETAILED DESCRIPTION

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0033] Embodiment 1:

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8, Fig. 9 and Fig.10 As shown, a metallurgical casting anti-skid lifting device of the present invention comprises a lifting frame 1, a lifting mechanism 2 for transporting metallurgical materials is arranged on the lifting frame 1, a driven component 3 connected to the lifting mechanism 2 is arranged on the lifting frame 1, and a detection component 4 for detecting the skidding of the lifting mechanism 2 is arranged on the driven component 3;

[0035] A transmission component 5 is provided on the lifting frame 1, and a connecting component 6 for controlling the connection between the driven component 3 and the transmission component 5 is provided at the output end of the driven component 3, and the connecting component 6 and the detection component 4 are both electrically connected to the control system;

[0036] An adjusting component 7 is arranged on the transmission component 5, and a tensioning component 8 for adjusting the tension of the lifting mechanism 2 is arranged on the lifting frame 1. The operation of the transmission component 5 forces the adjusting component 7 to adjust the tensioning component 8 to automatically adjust the tension of the lifting mechanism 2, thereby realizing an automatic anti-skid function.

[0037] Working principle: The metallurgical materials are transported to a high place by using the lifting mechanism 2 and the lifting frame 1. Since the metallurgical materials have a certain weight, when the lifting mechanism 2 slips, it is necessary to use the tensioning component 8 to adjust it, adjust the adjusting component 7 to a reasonable state, and energize the adjusting component 7 so that the adjusting component 7 acts on the tensioning component 8, thereby causing the tensioning component 8 to tighten the lifting mechanism 2; during the action of the lifting mechanism 2, when the device operates normally, the driven component 3 moves synchronously with the lifting mechanism 2, so that the detection component 4 detects that the lifting mechanism 2 operates normally. At this time, no action is required, and the tensioning component 8 cooperates with the lifting mechanism 2 to continuously transport materials according to the original tensioning state; when the lifting mechanism 2 slips, the detection component 4 detects that the device is operating abnormally. At this time, the detection component 4 transmits data to the control system, and the control system forces the connecting component 6 to act, so that the driven component 3 is connected to the transmission component 5 to form a whole. When the driven component 3 moves, the transmission component 5 moves, and the transmission component 5 drives the adjusting component 7 to move. The adjusting component 7 adjusts Reduce its own resistance value to increase the current. When the current increases, the tensioning component 8 is forced to adjust the tension of the lifting mechanism 2, so that the tension of the lifting mechanism 2 is tightened, forcing the lifting mechanism 2 to work normally. At this time, the detection component 4 detects that the lifting mechanism 2 is working normally, and the control system controls the connection component 6 to disconnect, so that the driven component 3 is disconnected from the transmission component 5, and the lifting mechanism 2 resumes normal operation, completes automatic adjustment of the tension, and realizes the automatic anti-skid function. During the operation of the lifting mechanism 2, continuous power is guaranteed to ensure that the device continuously transports materials. In summary, a metallurgical casting anti-skid lifting device of the present invention can realize dynamic adjustment of the device without stopping the device when the device slips, and automatically completes the adjustment of the tension, thereby realizing the automatic anti-skid function and achieving the purpose of continuous feeding operation, improving the flexibility of the device, improving the conveying efficiency of the device, improving the feeding progress, saving time, and reducing production costs. At the same time, it ensures that the adjustment component 7 maintains a state, forcing the tensioning component 8 to continue to maintain a tensioned state to ensure the normal operation of the lifting mechanism 2.

[0046] like Figure 2 , Figure 4 and Figure 7 As shown, a metallurgical casting anti-skid lifting device of the present invention, the tensioning assembly 8 also includes a slide bar 806 arranged on the support plate 802, the slide bar 806 slides through the support plate 802, the end of the slide bar 806 is provided with a magnet block 807 adapted to the electromagnet 804, the end of the slide bar 806 is provided with a baffle plate 808, a spring 809 sleeved on the slide bar 806 is provided between the baffle plate 808 and the support plate 802, the baffle plate 808 is provided with a T-block 8010, the conveyor belt 204 is provided with a T-shaped slide rail 8011 along the conveying direction of the conveyor belt 204, and the T-block 8010 slides on the T-shaped slide rail 8011.

[0047] like Figure 6 and Fig.10 As shown, a metallurgical casting anti-skid lifting device of the present invention is provided with a limiting component 9 for limiting the toothed belt 301 on the fixed plate 302, the limiting component 9 includes a rotating shaft 901 connected to the fixed plate 302 by a bearing, a limiting wheel 902 is fixedly sleeved on the rotating shaft 901, and the limiting wheel 902 contacts the toothed belt 301 to limit the position of the toothed belt 301, so that the toothed belt 301 is meshed with the rotating gear 304.

[0048] Working principle: When conveying metallurgical materials, the metallurgical materials are placed in the containing box 205. At this time, a continuous material feeding device can be used to continuously feed the metallurgical materials into the containing box 205, and the motor 201 is started. The output shaft of the motor 201 rotates to drive the shaft 202 to rotate, and the shaft 202 rotates to drive the two rollers 203 to rotate. At this time, the conveyor belt 204 rotates to convey, driving the containing box 205 to continuously convey, forcing the containing box 205 to continuously collect metallurgical materials and continuously release metallurgical materials;

[0049] Under normal circumstances, the rotation of the conveyor belt 204 drives the toothed belt 301 to rotate, and the toothed belt 301 forces the rotating gear 304 to rotate. During the rotation of the toothed belt 301, the position of the toothed belt 301 is limited by the rotating shaft 901 and the limiting wheel 902, so that the toothed belt 301 is always engaged with the rotating gear 304, and the rotating gear 304 drives the rotating rod 303 to rotate. At this time, the rotating rod 303 drives the signal wheel 403 to rotate, and the wheel speed sensor 402 detects the normal rotation of the signal wheel 403. The wheel speed sensor 402 transmits data to the control system, and the control system analyzes the data and issues instructions. Under normal circumstances, the speed data of the control system is in a uniform motion state, and the connecting component 6 does not work at this time;

[0050] When the conveyor belt 204 starts to slip, the conveyor belt 204 and the roller 203 may slip due to insufficient tension of the conveyor belt 204. When the conveyor belt 204 and the roller 203 slip, the conveyor belt 204 may have an abnormal speed. When the wheel speed sensor 402 detects the abnormal speed, it transmits it to the control system, and the control system analyzes the data and issues instructions in time.

[0051] The control system controls the electric push rod 602 to start. Under the action of the fixed block 601, the output end of the electric push rod 602 drives the support frame 603 to move, and the support frame 603 drives the slip ring 604 to move, forcing the friction sleeve 605 to slide on the rotating rod 303. Since both the inner and outer sides of the friction sleeve 605 have a friction effect, when the friction sleeve 605 contacts the sleeve 502, due to the frustum of the friction sleeve 605, the sleeve 502 squeezes the friction sleeve 605, so that the friction sleeve 605 and the rotating rod 303 and the sleeve 502 are in close contact until the rotating rod 303, the friction sleeve 605 and the sleeve 502 are integrated. When the rotating rod 303 rotates, the rotating rod 303 drives the sleeve 502 to rotate. At this time, it is necessary to explain that when slipping, under the action of the conveyor belt 204 and other components, the rotating rod 303 will rotate continuously. When adjusting, it is adjusted according to the rotating rod 303 when rotating. When the rotating rod 303 does not rotate, it is not adjusted. Therefore, the device is adjusted when it just starts to slip.

[0052] The sleeve 502 drives the transmission gear 503 to rotate. Under the action of the adjustment component 7, the transmission gear 503 drives the spur rack 504 to move. The spur rack 504 drives the adjustment rod 703 to move linearly. Under the action of the adjustment plate 701, the adjustment rod 703 drives the conductive block 704 to move. The conductive block 704 contacts different positions of the resistor bar 702, so that the resistance value of the resistor bar 702 added to the circuit is reduced, resulting in an increase in the current of the circuit. The circuit forms a path. The power supply is connected to the contact head 2 706. The current passes through the resistor bar 702 and is transmitted to the contact head 1 705. After passing through the contact head 3 805 and the conductive rod 803, the current returns to the power supply to form a current path.

[0053] As the current in the circuit increases, the attraction of the electromagnet 804 on the conductive rod 803 increases, and the ability of the electromagnet 804 to attract the magnet block 807 increases. Under the action of the support plate 802, the magnet block 807 drives the slide bar 806 to slide, so that the magnet block 807 is close to the electromagnet 804. At this time, the spring 809 is compressed, and the slide bar 806 drives the baffle 808 to move. The baffle 808 drives the T-block 8010 to move toward the electromagnet 804, so that the T-block 8010 tightens the conveyor belt 204. The magnet blocks 807 are symmetrically arranged so that the conveyor belts 204 on both sides are tightened synchronously, thereby adjusting the tension of the conveyor belt 204. During the conveying process of the conveyor belt 204, since the conveyor belt 204 rotates around the roller 203, the T-shaped slide rail 8011 runs around the T-block 8010. When the electromagnet 804 is adjusted, the T-block 8010 is at a determined position.

[0054] After tightening the tension of the conveyor belt 204, when the wheel speed sensor 402 detects that the speed is normal, the control system issues a command to reversely start the electric push rod 602. Under the action of the fixed block 601, the output end of the electric push rod 602 drives the support frame 603 to move in the opposite direction, and the support frame 603 drives the slip ring 604 to move, forcing the friction sleeve 605 to slide in the opposite direction on the rotating rod 303, so that the friction sleeve 605 is separated from the sleeve 502. At this time, the adjustment component 7, the tensioning component 8 and the transmission component 5 do not move, the device returns to normal, and the conveyor belt 204 continues to transport metallurgical materials. When the material transportation is completed, the tension of the conveyor belt 204 is adjusted or repaired and replaced, and the device is restored to its original position;

[0055] The setting of the lifting mechanism 2 is convenient for driving the accommodating box 205 to rotate, thereby realizing the function of conveying metallurgical materials, so that the metallurgical materials are transported from a low place to a high place, and at the same time, the power of the conveyor belt 204 is provided, so that the conveyor belt 204 is continuously conveyed, and the anti-skid device uses the transmission power of the conveyor belt 204; the setting of the driven component 3 can drive the rotation of the conveyor belt 204, so that the rotation of the conveyor belt 204 drives the rotating rod 303 and the rotating gear 304 to rotate, thereby realizing the force transmission effect, thereby realizing the detection of the conveyor belt 204 and the adjustment of the tension of the conveyor belt 204; the setting of the detection component 4 is convenient for detecting the rotation speed of the rotating rod 303, Thereby, the speed detection of the conveyor belt 204 is realized. When the speed is abnormal, it indicates that the conveyor belt 204 is abnormal. When the speed keeps uniform motion, it indicates that the transmission between the conveyor belt 204 and the roller 203 is normal. The setting of the transmission component 5 transmits the force of the rotating rod 303 to the spur rack 504 and the adjusting rod 703, converting the circular motion into a linear motion, realizing the regulating effect of the regulating component 7, and cooperating with the connecting component 6 for dynamic connection. The setting of the regulating component 7 can adjust the resistance value of the resistor bar 702, thereby adjusting the magnitude of the current in the circuit, thereby increasing the magnetism of the electromagnet 804, and facilitating the control of the attraction of the electromagnet 804 to the magnet block 807. The setting of the adjusting rod 703 can transmit the movement of the spur rack 504, so as to adjust the position of the conductive block 704 on the resistor bar 702, so as to adjust the resistance value; the setting of the connecting component 6 can connect the rotating rod 303 and the sleeve 502 together, so as to realize the synchronous rotation of the sleeve 502 with the rotating rod 303, so as to realize the adjustment of the device, and at the same time, the rotating rod 303 can be separated from the sleeve 502, so that the sleeve 502 does not rotate with the rotating rod 303, thereby improving the flexibility of the device, making the device form the characteristics of dynamic adjustment, and improving the characteristics of continuous operation of the device; the setting of the tensioning component 8 can enable the electromagnet 804 to generate a strong attraction, so as to exert a strong attraction on the magnet block 80 7 is attracted, so that the magnet block 807 is in motion, and the tension of the conveyor belt 204 is adjusted. The setting of the T-block 8010 and the T-slide rail 8011 can realize the connection between the baffle plate 808 and the conveyor belt 204.
