Description

Technical Field

[0001] This utility model relates to the field of converter steelmaking, specifically to a converter steelmaking charging device. Background Technology

[0002] In the converter steelmaking process, the feeding process is a key step to ensure smelting efficiency and steel quality. It is necessary to accurately deliver materials such as ferroalloys and slagging agents into the converter.

[0003] Currently, most small and medium-sized steelmaking enterprises use manual labor combined with simple lifting devices for feeding. Materials need to be manually moved to the lifting device's hopper and then hoisted by a crane to the top of the converter for dumping. This method is not only labor-intensive and inefficient, but manual control of the dumping angle can easily lead to material spillage, posing safety hazards. Some enterprises have adopted mechanical feeding devices, but existing devices generally have two shortcomings: First, insufficient automation; the material lifting and dumping actions require multi-device coordination and control, resulting in poor linkage and difficulty in adapting to the fast-paced demands of continuous steelmaking. Second, material residue easily remains on the inner wall of the feeding box, especially for highly viscous slagging agents, leading to material waste and requiring regular manual cleaning, increasing maintenance costs. Therefore, a converter steelmaking feeding device needs to be designed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a converter steelmaking charging device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a converter steelmaking charging device, comprising a base, wherein two bases are provided, a U-shaped frame is fixedly installed on the top of the base, and a first sliding groove is provided on both sides of the inner wall of the U-shaped frame, a sliding rod is slidably connected inside the first sliding groove, a rotating rod is slidably connected to one end of the sliding rod through a slot, a charging box is fixedly installed between the two rotating rods, and a counterweight is fixedly installed at the bottom of the charging box;

[0006] A limiting rod is fixedly installed on the top of the base. The top of the limiting rod passes through the slide rod and the rotating rod in sequence and extends to the outside of the slide rod. The top of the rotating rod is provided with a limiting opening that cooperates with the limiting rod. Side strips are fixedly installed on both sides of the feeding box. A stop bar that cooperates with the side strips is fixedly installed on both sides of the top of the U-shaped frame cavity. A traction mechanism is provided on the top of the U-shaped frame.

[0007] Preferably, the traction mechanism includes a servo motor fixedly connected to the top of the U-shaped frame. The output shaft of the servo motor is fixedly mounted with a rotating rod via a coupling. A cable winder is fixedly mounted on the surface of the rotating rod. A pull rope is fixedly mounted at the bottom of the cable winder. The bottom end of the pull rope passes through the U-shaped frame and extends to the inner side of the U-shaped frame. The bottom end of the pull rope is fixedly connected to the top of the slide rod.

[0008] Preferably, the rear of the feeding box is provided with a movable groove, and a movable rod is slidably connected inside the movable groove. A push plate is fixedly installed at the front end of the movable rod.

[0009] Preferably, a third sliding groove is provided on both sides of the inner cavity of the movable groove, and a second sliding groove is provided on both sides of the movable rod.

[0010] Preferably, a slider is slidably connected between the interior of the second and third slide grooves on the same side.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This converter steelmaking charging device works by pouring the required material into the charging box, then controlling the servo motor to start. The servo motor drives the rotating rod to rotate, which in turn drives the winding device to rotate. The winding device winds up the rope, causing the sliding rod to rise. The rising sliding rod then raises the charging box. Once the charging box reaches a suitable height, the device can be moved above the converter body via rollers. Then, the servo motor is started again. At this point, the charging box moves the rotating rod until it disengages from the limit rod. Simultaneously, the stop rod can contact the side bar to cause the charging box to flip forward, thus emptying the material inside.

[0014] 2. This converter steelmaking charging device, by setting a pusher plate, allows the charging box to be flipped over and then moved forward by gravity. The pusher plate can contact the inner wall of the charging box to scrape off the material adhering to the inner wall of the charging box. Attached Figure Description

[0022] Example 1

[0023] Please refer to Figure 1-5 As shown, this utility model provides a converter steelmaking charging device, including a base 1. There are two bases 1. Rollers 14 are rotatably connected to the front and rear of one side of the base 1 through bearing components. A U-shaped frame 2 is fixedly installed on the top of the base 1. A first sliding groove 3 is opened on both sides of the inner wall of the U-shaped frame 2. A sliding rod 4 is slidably connected inside the first sliding groove 3. A rotating rod 5 is slidably connected to one end of the sliding rod 4 through a slot. A charging box 6 is fixedly installed between the two rotating rods 5. A counterweight block 22 is fixedly installed at the bottom of the charging box 6.

[0024] Specifically, a limiting rod 7 is fixedly installed on the top of the base 1. The top of the limiting rod 7 passes through the slide rod 4 and the rotating rod 5 in sequence and extends to the outside of the slide rod 4. The top of the rotating rod 5 is provided with a limiting port 8 that cooperates with the limiting rod 7. Side strips 9 are fixedly installed on both sides of the feeding box 6. A stop rod 21 that cooperates with the side strips 9 is fixedly installed on both sides of the top of the U-shaped frame 2. A traction mechanism is provided on the top of the U-shaped frame 2. The traction mechanism includes a servo motor 10 fixedly connected to the top of the U-shaped frame 2. A rotating rod 11 is fixedly installed on the output shaft of the servo motor 10 through a coupling. A winding device 12 is fixedly installed on the surface of the rotating rod 11. A pull rope 13 is fixedly installed on the bottom of the winding device 12. The bottom end of the pull rope 13 passes through the U-shaped frame 2 and extends to the inside of the U-shaped frame 2. The bottom end is fixedly connected to the top of the slide rod 4. By setting the feeding box 6, the material to be added is poured into the feeding box 6, and then the servo motor 10 is started. The servo motor 10 drives the rotating rod 11 to rotate, and the rotating rod 11 drives the winding device 12 to rotate. The winding device 12 can wind up the pull rope 13. The winding of the pull rope 13 causes the slide rod 4 to rise. The rise of the slide rod 4 drives the feeding box 6 to rise. After the feeding box 6 rises to a suitable height, the device can be moved to the top of the converter body by the roller 14. Then, the servo motor 10 is started again. At this time, the feeding box 6 drives the rotating rod 5 to move until it is disengaged from the limit rod 7. At the same time, the abutment rod 21 can contact the side bar 9 to make the feeding box 6 flip forward. The forward flip of the feeding box 6 achieves the effect of pouring out the material inside.

[0025] Specifically, the rear of the feeding box 6 is provided with a movable groove 15, and a movable rod 16 is slidably connected inside the movable groove 15. A push plate 17 is fixedly installed at the front end of the movable rod 16.

A slider 20 is slidably connected between the inner sides of the second sliding groove 18 and the third sliding groove 19 on the same side. By setting the push plate 17, the push plate 17 can move forward by gravity after the feeding box 6 is flipped. The movement of the push plate 17 can achieve the effect of scraping off the material attached to the inner wall of the feeding box 6 by contacting the inner wall of the feeding box 6.

[0026] Working Principle: This utility model is a charging device for converter steelmaking. The material to be added is poured into the charging box 6, and then the servo motor 10 is started. The servo motor 10 drives the rotating rod 11 to rotate, which in turn drives the winding device 12 to rotate. The winding device 12 winds up the pull rope 13, causing the sliding rod 4 to rise. The rising of the sliding rod 4 drives the charging box 6 to rise. After the charging box 6 rises to a suitable height, the device can be moved above the converter body via rollers 14. Then, the servo motor 10 is started. At this time, the feeding box 6 drives the rotating rod 5 to move until it is disengaged from the limit rod 7. At the same time, the abutment rod 21 can contact the side strip 9 to make the feeding box 6 flip forward. The feeding box 6 flips forward to pour out the material inside. At the same time, by setting the push plate 17, the feeding box 6 can move forward by gravity after it flips. The push plate 17 can contact the inner wall of the feeding box 6 to scrape off the material attached to the inner wall of the feeding box 6.
