Description
Technical Field
[0001] The utility model relates to the technical field of slag blocking plug placement, in particular to a swing bracket assembly for an automatic storage 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, manual lifting and insertion has been adopted, and the automatic filling of slag plug technology equipment has been 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-out 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 entire process low, and there is a lack of information data collection, but it also requires a relatively high labor cost. For smaller tonnage converters equipped with slag blocking plug placing devices, under the conditions of manual lifting and insertion of the slag blocking plug, the dead weight of the slag blocking plug exceeds the ergonomic lifting condition of forearm bending and a lifting force of approximately 150 Newtons. With the help of the slag blocking plug being lifted against the abdomen, the loading process can barely be completed. 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 25 kilograms. From the perspective of occupational health requirements, it is not suitable to adopt a manual lifting and insertion operation method. Therefore, the present application proposes an automatic storage device with a swing bracket assembly to solve the above problems. Utility Model Content

[0026] A plurality of sliders are fixed to the lower surface of the base plate 1, and the same slider is fixed to the lower surfaces of the plurality of sliders. The lower surface of the slider is provided with two open holes, and two guide rails 6 are respectively slidably connected inside the two open holes. The swing bracket assembly of the automatic storage device is installed on the swivel bracket for carrying the lifting bracket. The swivel bracket has a column at the center and two sets of ring-shaped welding structures at the edges. The swing bracket assembly and the swing angle positioning assembly are carried to rotate around the central axis. The lifting bracket is mainly composed of a supporting ring, a support rod, a sheath, a vertical rib plate, a welding structure constructed by a connecting plate and a supporting plate, and a buffer pad.
[0027] See also Figure 4The swing shaft assembly 2 in this embodiment includes a swing shaft body 203 cantilevered and connected between two guide rails 6. The outer side of the swing shaft body 203 is rotatably connected to a first shaft sleeve 202 through a bearing. A bearing seat 201 is fixed to the outer side of the first shaft sleeve 202. Multiple swing bracket assemblies are evenly distributed on the circumference of the rotating bracket and can rotate with the rotating bracket at the same time. The swing angle positioning assembly is installed in the middle part of the upper and lower annular structures of the rotating bracket, which is used for swing angle limit control of the guide rail 6 and as a support body of the follower. The swing angle positioning assembly includes upper and lower seat plates, positioning plates, pneumatic struts, transition joints, and screws. The swing bracket assembly allows the lifting bracket to make linear displacement in the swing bracket assembly, and the swing bracket assembly also has the function of swinging around a fixed axis.
[0028] In this example, the swing shaft body 203 is inserted between the two guide rails 6 in a cantilever manner and is connected with screws. The back side of the bearing seat 201 is fixed with multiple bolt columns by bolts. An external lifting bracket can be installed on the slide plate, and the external lifting bracket can move linearly along the guide rail 6. The tipping moment generated by the guide rail 6 in a vertical or inclined position due to the suspended installation method is balanced by the contact between the surface of the external follower roller and the plane of the positioning plate of the swing angle positioning assembly.

[0030] In this example, the top end of the angle positioning shaft body 301 is inserted into the preset holes in the middle of the two guide rails 6 and fastened by screws, and the heavy-duty cam bearing follower body 301 is perpendicular to the axis of the angle positioning shaft body 301.
[0031] See also Figure 6 The follower shaft assembly 4 in this embodiment includes a stop sleeve shaft 401 installed between the two guide rails 6 by bolts, and a drum wheel 402 with an embedded self-sliding bearing is installed on the outer side of the stop sleeve shaft 401. The bottom end of the stop sleeve shaft 401 is fixed with a locking shaft 403 through a nut washer. Due to the swing of the guide rail 6, the drum wheel and the stop arm assembly of the slag plug automatic filling device are displaced in the vertical direction at the same time. The rolling contact mechanism between the two can prevent the occurrence of sliding hard friction, and effectively improve the stability of the combined motion of the guide rail 6 rotating around the center of the slewing bracket and around the swing axis at the same time. The limit shaft 5 is installed at the bottom of the base plate 1, which is used to limit the stroke of the slide plate and prevent it from falling.

Multiple swing bracket assemblies are evenly distributed on the circumference of the rotating bracket and can rotate with the rotating bracket at the same time. The swing bracket assembly allows the lifting bracket to make linear displacement within the swing bracket assembly. The swing bracket assembly also has the function of swinging around a fixed axis. An external lifting bracket can be installed on the skateboard, and the external lifting bracket can move in a straight line along the guide rail 6, effectively improving the stability of the guide rail 6 rotating around the center of the rotating bracket and the composite motion around the swing axis at the same time.
