Technical Field
[0001] The utility model relates to the technical field of RH impregnated pipe production, in particular to a placement device for RH impregnated pipe ring bricks. Background Art
[0002] RH refining furnace is a smelting equipment in the hot processing industry. It is mostly used for final deoxidation and alloying of molten steel in ferrous metallurgy. It has a wide application market in the metallurgical field. The immersion tube is an important component of the RH refining furnace. The RH immersion tube is composed of ring bricks, self-flowing materials, steel bladder and castable materials from the inside to the outside.
[0003] During casting, the ring bricks that have been ground and bonded need to be placed inside the steel bladder. Since the distance between the ring bricks and the steel bladder is between 20 and 30 mm, it is difficult to put the ring bricks into the steel bladder after the commonly used outer clamping tools clamp the outer side of the ring bricks. Therefore, the ring bricks are fixed and placed in the steel bladder by a crane and a rope. However, the rope is wrapped around the outside of the steel bladder, which is not only easy to slip off, but also very troublesome to untie after the ring bricks are placed. It is time-consuming and labor-intensive, affecting work efficiency. Summary of the invention

DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments (for the convenience of description and understanding, the following is a schematic diagram of the present invention). Figure 2 Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.
[0017] See also Figure 1-3The utility model provides a technical solution: a device for placing RH impregnation tube ring bricks, comprising a suspension rod 1, a suspension ring 2 is arranged at the upper end of the suspension rod 1, the suspension ring 2 is connected to a hook on a crane, a support mechanism 3 for supporting the bottom of the ring brick is arranged at the lower end of the suspension rod 1, the support mechanism 3 comprises a support block 31, a first electric push rod 33, a first fixed block 32, a second fixed block 35 and a support plate 36, the support block 31 is fixed to the lower end of the outer side surface of the suspension rod 1, the interior of the support block 31 is a cavity, the support plate 36 is located in the support block 31 and can move laterally in the support block 31 A strip hole 34 is provided at the upper end of the support block 31, and the second fixing block 35 is fixed to one end of the upper surface of the support plate 36. The second fixing block 35 passes through the strip hole 34. The first fixing block 32 is provided on the upper surface of the support block 31. The first electric push rod 33 is provided between the first fixing block 32 and the second fixing block 35. The telescopic end of the first electric push rod 33 is connected to the second fixing block 35. The extension and retraction of the support plate 36 are controlled by the first electric push rod 33 to realize the support and detachment of the ring brick, which is convenient for workers to operate. The support plate 36 does not exceed 10mm outside the ring brick.
[0018] In order to improve the support stability of the ring bricks, the number of the support mechanisms 3 is four, and the four support mechanisms 3 are evenly distributed on the outer side surface of the lower end of the suspension rod 1.
[0019] Furthermore, in order to facilitate the detachment of the support plate 36 and to prevent the ring bricks from suddenly falling and causing certain damage after the support plate 36 detaches from the support for the ring bricks, four guiding mechanisms 4 are symmetrically arranged on the outer side of the suspension rod 1. The four guiding mechanisms 4 are arranged in two layers, each layer has two guiding mechanisms 4 and are symmetrically arranged on the outer side of the suspension rod 1. The guiding mechanisms 4 are located above the supporting mechanism 3. The guiding mechanisms 4 include a second electric push rod 41, a U-shaped frame 42 and a guide wheel 43. The second electric push rod 41 is fixed to the outer side of the suspension rod 1, and the U-shaped frame 42 is connected to the telescopic end of the second electric push rod 41. The guide wheel 43 is located in the U-shaped frame 42, and the two end surfaces of the guide wheel 43 are rotatably connected to the U-shaped frame 42 through a pin shaft. Before the support plate 36 is retracted, the guide wheel 43 is controlled by the second electric push rod 41 to extend and contact the inner wall of the ring brick and provide appropriate pressure. After the support plate 36 is retracted, it slowly slides down under the gravity of the ring brick itself.
[0020] The input ends of the first electric push rod 33 and the second electric push rod 41 are both electrically connected to the output end of the external control switch.
[0021] In order to facilitate the installation of the second electric push rod 41 , the contact surface between the fixed end of the second electric push rod 41 and the suspension rod 1 is a plane 44 .
[0022] In order to increase the friction between the guide wheel 43 and the inner wall of the ring brick so that the ring brick can fall slowly, the outer side surface of the guide wheel 43 is covered with rubber.
[0023] When in use: it is connected to the lifting ring 1 through the crane hook, the lifting rod 2 is located in the ring brick, and the supporting mechanism 3 is located below the ring brick. At this time, the first electric push rod 33 is started, and the support plate 36 is extended. At this time, the support plate 36 is located directly below the lower end surface of the ring brick. The crane raises the lifting rod 1, and the four support plates 36 hold up the ring brick. Then the crane moves to the top of the steel sleeve and lowers the ring brick into the steel sleeve. When the support block 31 is about to contact the mold base, the second electric push rod 41 is started to make the guide wheel 43 extend and contact the inner wall of the ring brick to provide a certain friction force. Then the first electric push rod 33 is retracted to retract the support plate 36. Under the action of gravity, the ring brick slowly falls along the guide wheel 43 to the mold base, completing the placement process of the ring brick.
[0024] The utility model can quickly place the ring bricks into the steel sleeve, reduce the labor intensity of workers and improve work efficiency; by arranging the guide wheel 43, it is convenient to buffer the ring bricks when they fall, avoid damage to the ring bricks, and improve the convenience of use.
