Abstract
Description
Technical Field
[0001] This patent relates to the field of slag-grabbing devices, specifically an automatic slag-grabbing device for blast furnace slag. Background Technology
[0002] Converter gas is an important secondary energy source for steel enterprises. Increasing the recovery rate of converter gas can not only effectively reduce the production cost of steelmaking processes and lay the foundation for achieving "negative energy" steelmaking, but also effectively reduce the total amount of pollutants emitted by steel plants, achieving clean production. Slag cranes, as important equipment for handling slag, play a crucial role in the entire post-processing stage. If slag is not removed from the slag pool in a timely manner, high-temperature water and slag will overflow, affecting the normal operation of upstream production lines.
[0003] However, existing slag-grabbing devices still have some shortcomings. For example, the angle of the slag-grabbing device is not easy to adjust relative to the position of the slag truck and the slag pile, which affects the slag transportation efficiency. Therefore, it is necessary to improve the existing technology. Utility Model Content

It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.
[0028] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This is a schematic diagram of the structure of this patent. An automatic slag-grabbing device for blast furnace slag includes two parallel movable base plates 1, each top of which is fitted with a supporting base plate 2. Each top of the supporting base plate 2 is fitted with a supporting top plate 6, and an adjusting mechanism 7 is installed between the two supporting top plates 6. The adjusting mechanism 7 includes a threaded rod 71, a bearing seat 73, an inner screw cylinder 72, and a servo motor 74. The bearing seat 73 is installed on the inner wall of one side of the supporting top plate 6; a rotating hole is opened on the side wall of the other side of the supporting top plate 6, and the rotating hole is on the same horizontal line as the bearing seat 73; one end of the threaded rod 71 is installed inside the bearing seat 73, and the other end of the threaded rod 71 is installed... Inside the rotating hole, the inner screw barrel 72 is screwed to the outside of the threaded rod 71. The servo motor 74 is mounted on the side wall of the bearing top plate 6, and the threaded rod 71 is connected to the drive end of the servo motor 74. A fixed seat 8 is installed at the bottom end of the inner screw barrel 72, and a slag-grabbing mechanism 6 is installed at the bottom end of the fixed seat 8. A slide block 15 is installed at the top of the two movable bases 1, and a slider is installed at the bottom end of the bearing base plate 2. The slider is installed inside the slide block 15. Universal wheel assemblies are installed on both sides of the bottom end of the two movable bases 1. The bearing base plate 2 is vertically installed on the upper end of the movable base plate 1, and the bearing top plate 3 is installed on the upper end of the bearing base plate 2. The slag-grabbing mechanism 3 can be adjusted left and right by adjusting the mechanism 7.
[0029] The slag grabbing mechanism 3 includes two slag grabbing buckets 14 arranged opposite to each other. A U-shaped seat 13 is installed at the top of the two slag grabbing buckets 14. A hinge shaft is installed on the inner wall of both sides of the U-shaped seat 13. One hinge shaft is connected to one slag grabbing bucket 14, and the other hinge shaft is connected to the other slag grabbing bucket 14. A servo motor 9 is installed at the bottom of the fixed seat 8. A drive screw 10 is assembled at the drive end of the servo motor 9. An inner screw plate 11 is screwed to the outside of the drive screw 10. The two slag grabbing buckets 14 can be opened and closed by the hinge shafts.
[0030] A connecting plate 12 is assembled between the inner screw plate 11 and the two slag grabbing buckets 14. The connecting plate 12 is made of elastic material.
[0031] An electric push rod 5 is installed at the top center of the bearing base plate 1. The top of the electric push rod 6 is connected to the bearing top plate 5. The lifting and lowering of the bearing top plate 2 can be adjusted by extending and retracting the electric push rod 6.
[0032] Telescopic rods 4 are installed on both sides of the top of the supporting base plate 1. The top of the telescopic rods 4 is connected to the supporting top plate 6. The telescopic rods 4 can improve the lifting stability of the supporting top plate 2.
[0033] The caster assembly includes a galvanized bracket 15 installed at the lower end of the load-bearing base plate 1. The lower inner end of the galvanized bracket 15 is fitted with a wheel hub 19 via a screw 20 and a nut 21. Both outer ends of the wheel hub 19 are fitted with tire mounting brackets 18, and tires 17 are fitted onto the outside of the tire mounting brackets 18.
[0034] The wheel hub 19 and the tire mounting bracket 18 are provided with a first screw hole 25 opposite to each other. A first bolt 26 is screwed into the first screw hole 25. By making the tire mounting bracket 18 fit on the outside of the wheel hub 19 and fastening the tire mounting bracket 18 to the wheel hub 19 with the first bolt 26, it is easy to remove the tire mounting bracket 18 from the wheel hub 19.
[0035] Both ends of the inner wall of the wheel hub 19 are provided with reserved grooves 22. The reserved grooves 22 and the tire mounting bracket 18 are provided with corresponding second screw holes 23. A second bolt 24 is screwed into the second screw hole 23. By opening the second screw hole 23 and screwing the second bolt 24 into the second screw hole 23, the installation between the wheel hub mounting bracket 8 and the wheel hub 19 is made more secure.
[0036] Both the tire mounting bracket 18 and the tire 19 are semi-circular in shape. The tire 19 is fixedly glued to the outside of the tire mounting bracket 18. When the tire 19 needs to be replaced, since the tire 19 has been damaged, it is pried off the tire mounting bracket 18 with the help of tools. The tire 19 is a polyurethane tire. Polyurethane tires have a wide range of applications and have good wear resistance and hardness, which improves the service life of the tire.
[0037] Working process and principle: In use, first, move the slag-carrying vehicle between the slag-grabbing mechanism 3 and the slag pile. Then, move the slag-grabbing mechanism 3 to the top of the slag pile by adjusting the mechanism 7. Then, control the electric push rod 5 to retract and move the slag-grabbing mechanism 3 onto the slag pile. Grab the slag by opening and closing the two slag-grabbing buckets 14. Finally, move the slag-grabbing mechanism 3 onto the hopper of the slag-carrying vehicle.
