Description

Technical Field

[0001] The utility model relates to the technical field of slag stopper plugging, in particular to a cantilever rod clamping and positioning structure for a slag stopper plugging device. Background Art

[0002] The converter steelmaking plants in the steel industry have been using slag plug placing devices for more than 20 years. The corresponding process has a good effect on improving the quality of molten steel and is low-cost. However, in the preparation method for installing the slag plug on the slag plug placing device, the manual lifting and insertion method has been adopted. The automatic loading slag plug technology equipment is blank. Under the current trend of large-scale main steelmaking equipment, automation, informatization, and intelligent requirements of placing devices, and increasingly perfect occupational health and safety environment requirements, it is necessary to upgrade the slag blocking process technology equipment.

[0003] The existing slag blocking steel-making process is only equipped with a placing device for the slag blocking plug placing process, but the corresponding equipment is not configured in the slag blocking plug loading link. Since the slag blocking plug loading process adopts a manual lifting and insertion method, in addition to the configuration of the loading personnel, it is also necessary to configure operators on the placing device. Not only is the degree of automation of the whole process low, but there is a lack of information data collection. It also requires higher labor costs. For smaller tonnage converters equipped with slag blocking plug placing devices, under the condition of manual lifting and insertion of the slag blocking plug, since the dead weight of the slag blocking plug exceeds the ergonomic forearm bending and the lifting condition of about 150N, the loading process can be barely completed by lifting the slag blocking plug against the abdomen. With the development of large-scale converters and the increase in the diameter of the converter tapping port, the dead weight of the slag blocking plug is generally more than 25kg. From the perspective of occupational health requirements, it is no longer suitable to adopt the manual lifting and insertion operation method. Utility Model Content

[0006] The clamping mechanism includes an adjustment component and a fixing component. The adjustment component includes a base plate fixed to the upper surface of the column. A base and an angle cylinder are fixed to the left side of the upper surface of the base plate, and a buffer pad is fixed to the right side of the upper surface of the base plate. A pin is fixed to the output shaft of the angle cylinder, and a support shaft is rotatably connected to the outer surface of the pin. A support is fixed to the upper surface of the base.

[0007] Furthermore, the fixing assembly includes an upper cover fixed to the upper surface of the support, a first bearing is fixed inside the upper cover, a second bearing is fixed inside the support, a pressure arm is fixed on the outer surface of the support shaft, a first proximity switch is fixed on the left side of the support, and a second proximity switch is fixed on the back side of the support.

[0008] Furthermore, the cantilever rod body abuts against the upper surface of the buffer pad, and the upper surface of the cantilever rod body abuts against the lower surface of the pressure arm.

[0009] Furthermore, the base is U-shaped, and the support shaft is slidably connected to the inside of the first bearing and the second bearing.

[0010] Furthermore, the support is a cylindrical structure, the upper part of the support is a structure that cooperates with the upper cover, the lower part of the support is a boss hole structure, and a hole is opened within a 90° range in the middle of the side wall of the support.

Through the clamping mechanism, before the cantilever rod body is rotated to the loading position, the piston rod of the angular cylinder is in the highest position of 0°, and the pressure arm is in the highest position of 0° parallel to the axis of the cantilever rod body at the loading position. The second proximity switch confirms, so that the cantilever rod body is rotated to the loading position. The first proximity switch receives a signal, the piston rod of the angular cylinder starts the retraction process, and the pressure arm continuously rotates 90° to realize the pressing action. When the pressure arm arrives, it stops and the cantilever rod body is clamped and positioned. The fixation is convenient and the fixing effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

The adjusting component includes a base plate 313 fixed to the upper surface of the column 1, and a base 309 and a rotation cylinder 311 are fixed to the left side of the upper surface of the base plate 313. A buffer pad 312 is fixed to the right side of the upper surface of the base plate 313 for placing the cantilever rod body 4. A pin 310 is fixed to the output shaft of the rotation cylinder 311, and the outer surface of the pin 310 is rotatably connected to the support shaft 304, which is driven to rotate by the rotation cylinder 311. A support 301 is fixed to the upper surface of the base 309.

[0023] The fixing assembly includes an upper cover 302 fixed to the upper surface of the support 301, a first bearing 303 is fixed inside the upper cover 302, a second bearing 306 is fixed inside the support 301, a pressure arm 305 is fixed on the outer surface of the support shaft 304 for fixing the cantilever rod body 4, a first proximity switch 307 is fixed on the left side of the support 301, and a second proximity switch 308 is fixed on the back side of the support 301 for detecting the position of the support shaft 304.

[0024] Among them, the cantilever rod body 4 is abutted against the upper surface of the buffer pad 312, and the upper surface of the cantilever rod body 4 is abutted against the lower surface of the pressure arm 305. The cantilever rod body 4 is clamped by the cooperation of the buffer pad 312 and the pressure arm 305. The base 309 is U-shaped, and the support shaft 304 is slidably connected to the inside of the first bearing 303 and the second bearing 306, thereby increasing the stability of the support shaft 304 when moving.

[0025] In addition, the support 301 is a cylindrical structure, the upper part of the support 301 is a structure that cooperates with the upper cover 302, the lower part of the support 301 is a boss hole structure, and a hole is opened within a 90° range in the middle of the side wall of the support 301 to facilitate the pressure arm 305 to clamp and fix the cantilever rod body 4, the first bearing 303 is an F-type with a flange, and the support shaft 304 is a stepped shaft with a flange in the middle and a fork structure at the bottom.

[0026] In addition, the pressure arm 305 is a combined welded structure of a cylinder with a flange and a cantilever. The center of the cylinder of the pressure arm 305 is for the support shaft 304 to pass through, and the support shaft 304 cooperates with the upper flange to facilitate the movement of the support shaft 304. The clamping part corresponding to the pressure arm 305 is milled with a half-moon shaped groove structure corresponding to the diameter of the cantilever rod body 4. The pressure arm 305 and the support shaft 304 are connected by screws. The pressure arm 305 and the support shaft 304 are integrated into one and inserted into the support 301. The upper cover 302 is installed on the upper part of the support 301 and fixed with screws. The pressure arm 305 and the support shaft 304 after being integrated can rotate 90° and move up and down within a certain range in the support 301.

[0027] It should be noted that the angular cylinder 311 has a compound motion function of 90° rotation and a certain range of up and down motion. The head of the piston rod of the angular cylinder 311 is a flat head structure, which is connected to the fork pin at the bottom of the support shaft 304 through the pin 310. The bottom of the angular cylinder 311 is bolted to the base 309. When the piston rod of the angular cylinder 311 is fully extended, the pressure arm 305 connected to the piston rod is at the highest position of 0°. When the piston rod of the angular cylinder 311 extends a stroke, the pressure arm 305 rotates to the 90° position, and the piston rod continues to extend. The pressure arm 305 remains at the 90° position but its height decreases.

[0028] The buffer pad 312 is installed on the bottom plate 313 by bolt connection, and is used to support the cantilever rod body 4 of the slag stopper delivery device rotated to the filling position.

The second proximity switch 308 confirms, so that the cantilever rod body 4 rotates to the loading position, and the first proximity switch 307 receives a signal, and the piston rod of the angular cylinder 311 starts the retraction process, and the pressing arm 305 continuously rotates 90° to realize the pressing action. When the pressing arm 305 arrives, it stops and the cantilever rod body 4 is clamped and positioned.

[0030] The working principle of the above embodiment is:

[0031] Before the cantilever rod body 4 of the slag stop plug delivery device rotates to the loading position, the piston rod of the angular cylinder 311 is at the highest position of 0°, and the pressure arm 305 is at the highest position of 0° parallel to the axis of the cantilever rod body 4 at the loading position. The second proximity switch 308 on the support 301 confirms that the cantilever rod body 4 of the slag stop plug delivery device rotates to the loading position, and the first proximity switch 307 receives a sensing signal, and the piston rod of the angular cylinder 311 starts the retraction process. At this time, the pressure arm 305 continuously rotates 90° to realize the pressing action. When the pressure arm 305 arrives, it stops and cooperates with the buffer pad 312 to clamp and position the cantilever rod body 4.
