Description

Technical Field

[0001] This invention relates to the field of ladle technology, specifically to a sand-adding device that reduces the consumption of diversion sand and improves the ladle self-opening rate. Background Technology

[0002] A ladle, also known as a steel ladle or furnace ladle, is a container used to hold molten steel during the steelmaking process. Ladles are typically composed of refractory materials and structural steel, possessing properties such as high temperature resistance, corrosion resistance, and wear resistance. They are used to receive molten iron from a blast furnace or electric furnace and, through a series of smelting and tempering processes, ultimately produce molten steel that meets the required standards. The design and manufacture of a ladle must consider multiple factors, such as the temperature, chemical composition, oxide content, and fluidity of the molten steel.

[0003] The ladle self-opening rate has always been an important factor related to production safety and smooth operation. Due to the waste of diversion sand caused by manual throwing and uneven coverage, the ladle self-opening rate is poor. Furthermore, there are a series of safety hazards such as backfire and burns when manually burning oxygen. Therefore, in order to address the above problems, we need to propose a sand adding device that reduces diversion sand consumption and improves the ladle self-opening rate. Summary of the Invention

[0004] The purpose of this invention is to provide a sand-adding device that reduces the consumption of diversion sand and increases the self-opening rate of the ladle, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sand-adding device for reducing the consumption of diversion sand and improving the self-opening rate of the ladle, comprising a base plate, with four legs fixedly connected to the top of the base plate, an operating platform fixedly connected between the tops of the four legs, a climbing ladder provided on the right side of the bottom of the operating platform, a connecting frame fixedly connected to the top of the operating platform, auxiliary wheels fixedly connected to the front and rear sides of the top two sides of the connecting frame, a traction rope movably connected between the surfaces of two auxiliary wheels, a counterweight fixedly connected to the bottom left side of the traction rope extending to the bottom of the operating platform, a connecting plate fixedly connected to the bottom right side of the traction rope, a long-tube sand-adding funnel fixedly connected to the inner cavity of the connecting plate, a limit shell fixedly connected to the top of the base plate, an auxiliary component provided on the front side of the top of the base plate, the auxiliary component including a motor and an auxiliary rope, and a ladle mechanism provided on the right side of the operating platform.

[0007] Preferably, a retaining ring is fitted on the surface of the connecting seat, and the bottom of the retaining ring is fixedly connected to the traction plate.

[0008] Preferably, the bottom of the motor is fixedly connected to the base plate, the output end of the motor is fixedly connected to a transmission rod, the rear side of the transmission rod passes through the inner cavity of the limiting shell and is fixedly connected to a take-up roller, the surface of the take-up roller is wound and connected to an auxiliary rope, the left side of the auxiliary rope passes through the outer side of the limiting shell and is fixedly connected to an auxiliary shell, and the inner cavity of the auxiliary shell is movably connected to a counterweight.

[0009] Preferably, a traction wheel is movably connected to the surface of the auxiliary rope, and the top of the traction wheel is fixedly connected to the operating platform.

[0010] Preferably, a retaining block is fixedly connected to both sides of the motor, and the bottom of the retaining block is fixedly connected to the base plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention involves hoisting the ladle body to the sand-filling position after hot repairs are completed. Operators lower the long-tube sand-filling funnel. When adjusting the funnel's position, a counterweight can raise its height. To lower the funnel, the motor's output drives an auxiliary rope on the winding roller via a transmission rod. This rope pulls the counterweight inside the auxiliary housing upwards, causing the funnel to lower itself by its own weight. When the funnel reaches the nozzle, bagged guide sand is added and filled. Once the nozzle is full, forming a mushroom shape, sand filling stops. The funnel is then lifted, and the ladle body is hoisted off the operating platform for standby. This effectively reduces guide sand waste and saves costs. Simultaneously, it increases the self-opening rate during ladle turnover, reduces the labor intensity of continuous casting workers, and minimizes safety hazards associated with oxygen combustion during casting operations.

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.

[0024] Please see Figure 1-5As shown, a sand-adding device for reducing sand consumption and improving ladle self-opening rate includes a base plate 1. Support legs 2 are fixedly connected to the four corners of the top of the base plate 1. An operating platform 3 is fixedly connected between the tops of the four support legs 2. A climbing ladder 10 is provided on the right side of the bottom of the operating platform 3. A connecting frame 4 is fixedly connected to the top of the operating platform 3. Auxiliary wheels 5 are fixedly connected to the front and rear sides of the top two sides of the connecting frame 4. A traction rope 6 is movably connected between the surfaces of the two auxiliary wheels 5. The bottom left side of the traction rope 6 extends through to the bottom of the operating platform 3 and is fixedly connected to a counterweight 7. A connecting plate 11 is fixedly connected to the bottom right side of the traction rope 6. A long-tube sand-adding funnel 12 is fixedly connected to the inner cavity of the connecting plate 11. A limiting shell 8 is fixedly connected to the top of the base plate 1. An auxiliary component 9 is provided on the front side of the top of the base plate 1. The auxiliary component 9 includes a motor 901 and an auxiliary rope 904. A ladle mechanism is provided on the right side of the operating platform 3.

[0025] refer to Figure 1 , Figure 2 and Figure 5 As shown, the ladle mechanism includes a ladle body 14, with the end of a long tube sand funnel 12 inserted into the inner cavity of the ladle body 14. Three lifting ropes 15 are provided on the top of the ladle body 14, and a traction plate 16 is fixedly connected between the tops of the three lifting ropes 15. A connecting seat 17 is fixedly connected to the top of the traction plate 16, and a steel rope 19 is fixed to the top of the connecting seat 17. A retaining ring 18 is sleeved on the surface of the connecting seat 17, and the bottom of the retaining ring 18 is fixedly connected to the traction plate 16.

[0026] It should be noted that when the workers transfer the ladle body 14, the three lifting ropes 15 (two long and one short) can lift the ladle body 14 at an inclined angle, which makes it convenient for the workers to fill the diversion sand. The traction plate 16, together with the steel rope 19, can facilitate the workers to transfer the ladle body 14. The fixing ring 18 plays the role of positioning the connecting seat 17 on the traction plate 16.

[0027] refer to Figure 1 , Figure 3 and Figure 4 As shown, the bottom of the motor 901 is fixedly connected to the base plate 1. The output end of the motor 901 is fixedly connected to the transmission rod 902. The rear side of the transmission rod 902 passes through the inner cavity of the limiting shell 8 and is fixedly connected to the winding roller 903. The surface of the winding roller 903 is wound and connected to the auxiliary rope 904. The left side of the auxiliary rope 904 passes through the outer side of the limiting shell 8 and is fixedly connected to the auxiliary shell 906. The inner cavity of the auxiliary shell 906 is movably connected to the counterweight 7. The surface of the auxiliary rope 904 is movably connected to the traction wheel 905. The top of the traction wheel 905 is fixedly connected to the operating platform 3. Both sides of the motor 901 are fixedly connected to the retaining block 907. The bottom of the retaining block 907 is fixedly connected to the base plate 1.

[0028] It should be noted that: First, the output end of the motor 901 drives the auxiliary rope 904 on the surface of the take-up roller 903 to wind up through the transmission rod 902. At this time, the auxiliary rope 904 will pull the counterweight 7 in the auxiliary shell 906 upward inside the traction wheel 905. At this time, the long tube sand funnel 12 at the other end of the traction rope 6 will adjust its position by its own weight, thereby assisting the long tube sand funnel 12 in adjusting its position. By setting the traction wheel 905, the traction wheel 905 is movably connected to the counterweight 7, which plays a role in guiding the traction direction of the auxiliary rope 904. By setting the fixing block 907, the fixing block 907 is fixedly connected to the base plate 1, which plays a role in positioning and protecting the motor 901.

[0029] refer to Figure 1 , Figure 3 and Figure 5 As shown, slide rods 13 are movably connected to the front and rear sides of the inner cavity of the connecting plate 11. The bottom of the slide rods 13 is fixedly connected to the operating platform 3. A positioning ring 20 is sleeved on the bottom of the surface of the slide rods 13. The bottom of the positioning ring 20 is fixedly connected to the operating platform 3. A fixed seat 21 is fixedly connected to the bottom of the surface of the support leg 2. The bottom of the fixed seat 21 is fixedly connected to the base plate 1. Reinforcing plates 22 are fixedly connected to both sides of the limiting shell 8. The bottom of the reinforcing plate 22 is fixedly connected to the base plate 1.

[0030] It should be noted that: by setting up the slide rod 13, which is fixedly connected to the operating platform 3, it serves to limit the long tube sand funnel 12 inside the connecting plate 11; by setting up the positioning ring 20, which is fixedly connected to the operating platform 3, it serves to position the slide rod 13; by setting up the fixed seat 21, which is fixedly connected to the base plate 1, it serves to fix the support leg 2; and by setting up the reinforcing plate 22, which is fixedly connected to the base plate 1, it serves to position the limiting shell 8.

[0031] Working principle: After the ladle body 14 is hot-repaired, it is hoisted to the sand-filling position. The operator lowers the long-tube sand-filling funnel 12. When adjusting the position of the long-tube sand-filling funnel 12, the counterweight 7, in conjunction with the traction rope 6, can raise the height of the long-tube sand-filling funnel 12 through the connecting plate 11. When it is necessary to lower the position of the long-tube sand-filling funnel 12, the motor 901 is turned on. The output end of the motor 901 drives the auxiliary rope 904 on the surface of the winding roller 903 to wind up through the transmission rod 902. At this time, the auxiliary rope 904 will pull the counterweight 7 in the auxiliary shell 906 upward inside the traction wheel 905. At this time, the long-tube sand-filling funnel 12 at the other end of the traction rope 6 will be filled with sand. By adjusting its position using its own weight, when the position of the long-tube sand-adding funnel 12 is adjusted to the nozzle, the pre-cut bagged guide sand is lifted into the long-tube sand-adding funnel 12. The guide sand flows into the nozzle through the long tube at the front end of the long-tube sand-adding funnel 12. After the guide sand fills the nozzle and forms a mushroom head shape, the sand addition is stopped, and the remaining bagged guide sand is removed for later use. The long-tube sand-adding funnel 12 is then lifted, and the supervisor directs the ladle body 14 to be lifted off the operating platform 3 and put into standby. This effectively reduces the waste of guide sand and saves costs. At the same time, it increases the self-opening rate during the ladle turnover process, reduces the labor intensity of continuous casting workers, and reduces a series of safety hazards caused by oxygen burning during the start-up operation.
