Description

Technical Field

[0001] The utility model relates to the technical field of plugging holes of smelting furnaces, and particularly relates to a hole plugging device for aluminum alloy production. Background Art

[0002] In the process of aluminum alloy casting, the shaft casting speed is fast and the aluminum liquid flow rate is large. For a fixed smelting furnace, manual flow control is adopted, and the flow rate of aluminum liquid is not stable, which is easy to produce slag, resulting in the quality of round bars not being guaranteed at a high level. At the same time, when a major leakage accident occurs in the fixed smelting furnace or high-temperature melt overflows in the chute or other melt channels during the casting process, personnel cannot approach the fixed smelting furnace to carry out the hole plugging work, and the high-temperature melt cannot be effectively cut off. At present, most smelting furnaces use mechanical equipment (hole plugging devices) to carry out the hole plugging work.

[0003] One end of the hole plugging rod has a plug for plugging the melt outlet of the smelting furnace. One end of the plug is connected to a rod body, and the end of the rod body is connected to a counterweight for balancing the plug. There is a through connection hole on the rod body, and a connection clamp passes through the connection hole to connect the hole plugging rod and the driving part. Since some high-temperature melt will adhere to the smelting furnace, reducing the hole plugging efficiency, it is often necessary to change the position of the hole plugging rod to make it closer to the eyelet to meet the hole plugging requirements. When changing the position of the hole plugging rod, since the force exerted by the hole plugging rod on the smelting furnace also becomes larger, and the connection clamp is only connected to the hole plugging rod through a single rod, it is easy for the connection clamp to break in the connection hole, causing the hole plugging rod to fall off, which not only affects the work efficiency but also easily causes safety accidents. Summary of the Utility Model

[0004] Aiming at the technical problems existing in the background art, the purpose of the utility model is to provide a hole plugging device for aluminum alloy production, which increases the connection strength between the connection clamp and the hole plugging rod and prevents failures at the connection position.

[0005] To achieve the above purpose, the technical solution provided by the utility model is as follows:

[0006] A hole plugging device for aluminum alloy production includes a hole plugging rod, a driving part, and a connection clamp connecting the hole plugging rod and the driving part. A plurality of connection holes are provided on the hole plugging rod, a support block is provided on the connection clamp, rotating blocks are rotatably provided on both sides of the support block, a connecting rod is detachably provided on the rotating block, the connecting rod is connected to the connection hole, a limiting groove is provided below the rotating block, and a limiting plate extending into the limiting groove is provided at the lower end of the support block for restricting the rotation of the rotating block so that it is parallel to the support block and connected to one end of the hole plugging rod.

[0007] Preferably, a bolt is provided on the support block, the bolt passes through the support block and the connection clamp, and a nut is provided in cooperation with the bolt.

[0008] Preferably, rotating grooves are provided at both ends of the support block, and support rods are arranged in the rotating grooves.

[0009] Preferably, a connecting plate is provided at one end of the rotating block, and the connecting plate extends into the rotating groove and is rotatably connected to the support rod.

[0010] Preferably, through holes are provided on the rotating block, and the distance between the through holes and the bolts is the same as the distance between two adjacent connecting holes.

[0011] Preferably, a rotating shaft is arranged inside the connecting rod, and an arc-shaped retaining piece is rotatably connected to the rotating shaft.

[0012] Preferably, a groove I and a groove II are provided on the circumferential surface of the connecting rod, and both ends of the arc-shaped retaining piece extend out of the groove I and the groove II respectively.

[0013] The utility model has the following advantages and beneficial effects:

[0014] First, in the utility model, the rotating block is rotatably connected to both ends of the support block. When the bolt and the connecting rod are both connected in the connecting hole, the bottom end of the rotating block supports on the limiting plate. When the connecting clamp is in a relatively forward or backward position of the plugging rod, only the bolt and one of the connecting rods can be connected to the plugging rod. At this time, one of the connecting rods can be taken out, and the rotating block is rotated so that the connecting clamp can adapt to various connecting positions.

[0015] Second, in the utility model, the arc-shaped retaining piece can rotate inside the connecting rod. When the groove I extends into the rotating block, most of the arc-shaped retaining piece extends out of the groove II and is located at the bottom of the plugging rod, preventing wear of the bolt connection and the separation of the plugging rod from the connecting clamp. This method is convenient for disassembly and also strengthens the connection between the plugging rod and the connecting clamp.

[0016] Third, in the utility model, the structure is simple, the operation is convenient, and it is convenient to connect the plugging rod. Brief Description of the Drawings

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0028] Embodiment

[0029] As Figure 1-8 shown, a plugging device for aluminum alloy production includes a plugging rod 1, a driving member, and a connecting press clamp 2 that connects the plugging rod 1 and the driving member. A plug head 101, a rod body 102, and a counterweight 103 are provided at one end of the plugging rod 1. A plurality of connection holes 104 are provided on the plugging rod 1. The connecting press clamp 2 passes through the connection holes 104 and is connected to the plugging rod 1. The driving member drives the plugging rod 1 to move, realizing the work of plugging the melting furnace.

[0030] As Figure 1 、2 As shown in Figures 3, 7, and 8, the connecting clamp 2 is a prior art. One end of the connecting clamp 2 is fixedly connected to the driving member. Hold the grip end of the connecting clamp 2, and rotate the grip to fix the protruding end of the connecting clamp 2. A support block 3 is provided on the connecting clamp 2. A bolt 4 is provided on the support block 3. The bolt 4 passes through the support block 3 and the connecting clamp 2. The bolt 4 is provided with a nut in cooperation. When the connecting clamp 2 is connected to the plugging rod 1, the bolt 4 passes through one of the connecting holes 104, and a nut is connected to the bottom of the bolt 4 to connect the plugging rod 1 and the connecting clamp 2.

[0031] As Figure 1-8 As shown in the figure, rotating grooves 31 are provided at both ends of the support block 3. A support rod 32 is provided in the rotating grooves 31. Rotating blocks 5 are rotatably provided on both sides of the support block 3. One end of the rotating block 5 is provided with a connecting plate 51. The connecting plate 51 extends into the rotating groove 31 and is rotatably connected to the support rod 32 and rotates around the support rod 32. A connecting rod 6 is detachably provided on the rotating block 5. The connecting rod 6 is connected to the connecting hole 104. A limiting groove 52 is provided below the rotating block 5. A limiting plate 33 extending into the limiting groove 52 is provided at the lower end of the support block 3, which is used to limit the rotating block 5 to only rotate towards the end away from the plugging rod 1, so that it is parallel to the support block 3 and connected to one end of the plugging rod 1.

[0032] As Figure 1-8 As shown in the figure, a through hole 53 is provided on the rotating block 5. The distance between the through hole 53 and the bolt 4 is the same as the distance between two adjacent connecting holes 104. A rotating shaft 7 is rotatably connected to the inside of the connecting rod 6. An arc-shaped blocking piece 71 is rotatably connected to the rotating shaft 7. Groove I 61 and groove II 62 are provided on the circumferential surface of the connecting rod 6. Both ends of the arc-shaped blocking piece 71 respectively extend out from the groove I 61 and the groove II 62. When the connecting rod 6 needs to be inserted into the through hole 53, block the groove II 62 so that most of the arc-shaped blocking piece 71 extends out from the groove I 61, and put the connecting rod 6 into the through hole 53. At this time, the rotating block 5 is located between the groove I 61 and the groove II 62. When the connecting rod 6 needs to be connected to the plugging rod 1, repeat the above operation. The connecting rod 6 extends into the connecting hole 104 so that the plugging rod 1 is located between the groove I 61 and the groove II 62, and press the connecting rod 6 downward. The rotating block 5 blocks the groove I 61. At this time, most of the arc-shaped blocking piece 71 extends out from the groove I 61. When the bolt 4 is worn, the plugging rod 1 is separated from the connecting clamp 2, and the arc-shaped blocking piece 71 can support the lower end of the plugging rod 1. This method can connect the connecting clamp 2 and the plugging rod 1 through the connecting rod 6 and the bolt 4, which can not only strengthen the connection strength between each other, but also has simple operation.

[0033] As Figure 1-8As shown, when the connecting clamp 2 is located at the front or rear position of the blind hole plugging rod 1, and when the bolt 4 passes through the connecting hole 104 and there is only one connecting hole 104 on one side of the bolt 4, the connecting rod 6 on one side is removed, and the rotating block 5 is rotated to bend it on one side of the supporting block 3. On the original basis, an additional connecting rod 6 is added to increase the connection strength between the connecting clamp 2 and the blind hole plugging rod 1, and it can also prevent the connecting clamp 2 and the counterweight 103 from interfering with each other and affecting the connection quality.

[0034] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
