Description

Technical Field

[0001] The utility model relates to an installation device for a vacuum top-pouring flow guide pipe brick, belonging to the field of smelting equipment. Background Art

[0002] The flow guide pipe is a transition device between the tundish and the ingot mold for molten steel. It can collect the molten steel, ensure that the molten steel is poured into the ingot mold, and prevent the molten steel from diffusing outside the ingot mold under vacuum conditions. The flow guide pipe usually consists of a shell and an internal flow guide pipe brick. The design and material selection of the flow guide pipe will affect its erosion resistance, thermal stability, and service life, especially the refractory brick for the flow guide pipe - the flow guide pipe brick. For example, by adjusting the composition of the flow guide pipe brick, using the high strength and erosion resistance of alumina, and the high melting point and good chemical stability of zirconia, the stability and erosion resistance of the flow guide pipe brick at high temperatures can be improved. The graphite flow guide ring can avoid "nodulation" at the bottom when the molten steel flows through the flow guide pipe due to its non-wetting property with the molten steel.

[0003] It can be seen that in processes such as vacuum ingot casting, the flow guide pipe brick has an important impact on the quality of the ingot. During the construction of the flow guide pipe brick, manual handling is usually used, resulting in a large labor intensity. Moreover, the refractory material is easily knocked during handling, resulting in non-compliance with inclusion detection in the steel. Manual operation also makes the assembly of the flow guide pipe brick quite laborious.

[0004] Therefore, to solve the above problems, it is urgent to design an installation device for the flow guide pipe brick. Summary of the Invention

[0005] The utility model provides an installation device for a vacuum top-pouring flow guide pipe brick, which can complete the handling and installation of the flow guide pipe brick by mechanical hoisting, avoid damage to the flow guide pipe brick, and reduce the risk of foreign inclusions.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] An installation device for a vacuum top-pouring flow guide pipe brick includes a suspension rod, a sling support, and a gripping rod. At the middle position of the suspension rod, a plurality of sling supports are evenly installed along the circumference of the suspension rod. One gripping rod can be movably installed at the extending end of each sling support, and the bottom end of the gripping rod faces the ground;

[0008] A clamping space for clamping the flow guide pipe brick is formed between a plurality of gripping rods. The bottom end of the gripping rod bends and extends in the opposite direction of the suspension rod to form a clamping part. When hoisting the flow guide pipe brick, the gripping rod fits the inner wall of the flow guide pipe brick, and the clamping part supports the bottom end of the flow guide pipe brick;

[0009] As a further design of the utility model, the inside of the suspension rod is hollow, and a plurality of suspension ropes pass through from the top end of the suspension rod to the bottom end and extend out. The extended suspension ropes are connected to the bottom ends of the matching gripping rods;

[0010] As a further design of the present utility model, a number of guide tubes are fixed at a position near the bottom end inside the suspension rod, and the suspension ropes extend out of the bottom end of the suspension rod through the guide tubes; as a further design of the present utility model, the sling support includes a support rod and a connecting rod, the support rod is fixed on the circumference of the suspension rod, and the support rod is arranged perpendicular to the central axis of the suspension rod;

[0012] As a further design of the present utility model, the top end of the grasping rod is hinged to the extended end of the support rod;

[0013] As a further design of the present utility model, the position of the grasping rod near the bottom end is connected to the position of the suspension rod near the bottom end through a telescopic spring;

The whole structure is simple, and the movement of the diversion tube brick can be completed only by mechanically lifting the suspension rod;

[0017] 2.

Specific embodiments

[0024] Now, the present utility model will be further described in detail with reference to the accompanying drawings. In the description of this application, it should be understood that the orientation or positional relationship indicated by terms such as "left side", "right side", "upper part", "lower part", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not represent the importance of components, so it cannot be understood as a limitation to the present utility model. The specific dimensions adopted in this embodiment are only for illustrating the technical solution by way of example, and do not limit the protection scope of the present utility model.

[0025] As described in the background art, the handling and installation of the flow guide pipe brick mostly still rely on manual labor. If the refractory material is collided and damaged during manual handling, fragments will fall off and mix into the molten steel, resulting in non-compliance of the steel grade inclusion flaw detection. It is also quite laborious to assemble the flow guide pipe brick, and the labor efficiency is very low.

[0026] To solve the problems of high labor intensity caused by manual handling, non-compliance of steel inclusion flaw detection caused by bumping the refractory material, and laborious assembly, this application provides a vacuum top-pouring flow guide pipe brick installation device, including a suspension rod 1, a sling support, and a grasping rod 2. At the middle position of the suspension rod, a number of sling supports are evenly installed along the circumference of the suspension rod. The extended end of each sling support can be movably installed with a grasping rod, and the bottom end of the grasping rod faces the ground; a clamping space for clamping the flow guide pipe brick 9 is formed between several grasping rods. The bottom end of the grasping rod bends and extends in the opposite direction of the suspension rod to form a clamping part 5. When hoisting the flow guide pipe brick, the grasping rod fits the inner wall of the flow guide pipe brick, and the clamping part supports the bottom end of the flow guide pipe brick.

[0027] Figure 1 The figure shows the overall structural schematic diagram of the preferred embodiment provided by this application, which is designed with one suspension rod, three sling supports, and three matching grasping rods. After many tests and verifications, the engineers found that using three grasping rods in combination can ensure the stability of clamping the flow guide pipe brick, and at the same time ensure the lowest manufacturing cost. Preferably, Figure 2As shown in the figure, the sling support includes a support rod 3 and a connecting rod 4. The support rod is fixed on the circumference of the suspension rod, and the support rod is arranged perpendicular to the central axis of the suspension rod; one end of the connecting rod is fixed on the support rod, and the other end is fixed on the suspension rod. The connecting rod, the suspension rod and the support rod form a triangular structure, making the gripper rod more stable during hoisting.

[0028] The inside of the suspension rod is hollow, and several suspension ropes 6 pass through from the top end of the suspension rod to the bottom end and extend out. The extended suspension ropes are connected to the bottom end of the matching gripper rod. In a preferred embodiment, three suspension ropes are provided. The tops of the three suspension ropes are twisted into one strand at the top end of the suspension rod. Lifting machinery only needs to hook the twisted strand of suspension rope to implement the operation. Each suspension rope passes through the bottom end of the suspension rod and is connected to the corresponding gripper rod. This design achieves multiple effects. First, the suspension rope realizes the lifting purpose; secondly, the connection between the suspension rope and the gripper rod generates linkage. When the gripper rod moves into the flow guide pipe brick, the suspension rope is lifted upward under the action of the machinery. At this time, the connection end of the suspension rope and the gripper rod tightens, closely fitting the gripper rod and the inner wall of the flow guide pipe brick. The clamping part supports the bottom of the flow guide pipe brick and clamps the flow guide pipe brick. When the flow guide pipe brick is hoisted to the preset position in the flow guide pipe sleeve 10, the suspension rope falls downward under the action of the machinery to complete the unhooking operation, and the flow guide pipe brick is steadily lowered to complete the assembly; finally, because the suspension rope is a whole design, it can adjust the clamping position by itself to meet the actual working conditions.

[0029] Since the suspension rope is constantly adjusting to a suitable position during the hoisting process, the part extending from the bottom end of the suspension rod is easily worn by the pipe wall end of the suspension rod. Therefore, several guide pipes 7 are fixed at the position near the bottom end of the inner cavity of the suspension rod, and the suspension rope extends out of the bottom end of the suspension rod through the guide pipe; in a preferred embodiment, three guide pipes are provided to match the three suspension ropes.

[0030] During the hoisting process, not only is the suspension rope in a state of constant adjustment, but the gripper rod is also adjusting. Therefore, the top end of the gripper rod is hinged to the extended end of the support rod. At the same time, in order to avoid fine-tuning of the clamping space formed during the adjustment of the gripper rod, the position near the bottom end of the gripper rod is connected to the position near the bottom end of the suspension rod through a telescopic spring 8, and the fine-tuning purpose is achieved through the elasticity of the telescopic spring itself. Finally, as Figure 3 shown in the figure, the flow guide pipe brick is hoisted and assembled at the preset position.
