Description

Technical Field

[0001] The utility model relates to the technical field of blast furnace cast iron, in particular to a blast furnace cooling wall sleeve removal device. Background Art

[0002] The cooling stave is a type of cooler commonly used in blast furnaces. According to its material, it can be divided into cast iron cooling stave, copper cooling stave, steel cooling stave and steel-copper composite cooling stave.

[0003] At present, the existing cooling wall sleeve (such as patent number: CN217459475U) discloses a blast furnace cast steel cooling wall structure, which can facilitate the installation of cooling vertical pipes and connecting pipes on the surface of cooling horizontal pipes through multiple No. 1 threaded sealing grooves, No. 1 threaded sleeves, No. 2 threaded sealing grooves and No. 2 threaded sleeves, so that the multiple cooling horizontal pipes are connected through connecting heads, so that the cooling pipes inside the blast furnace can be easily replaced or repaired, avoiding the cooling pipes from being fixed and affecting the use of the blast furnace cooling wall.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems: the sleeve is connected to the cooling wall by a threaded connection. When the sleeve is fixed, the sleeve is clamped by a clamp and twisted to one side to disassemble the sleeve. However, the surface of the sleeve is relatively smooth. When the clamp is clamped under force, the friction between the inner side of the clamp and the surface of the sleeve is insufficient, which can easily cause slippage and affect the disassembly progress of the sleeve.

[0027] The embodiment of the present application provides a blast furnace cooling wall sleeve removal device, which effectively solves the problem that when the sleeve is fixed, the sleeve is clamped by a clamp and twisted to one side to remove the sleeve. However, the surface of the sleeve is relatively smooth. When the clamp is clamped and subjected to force, the friction between the inner side of the clamp and the surface of the sleeve is insufficient, which can easily cause slippage, affecting the disassembly progress of the sleeve. The fixing plate is allowed to slide on the top of the thrust rod, so that the thrust rod drives the clamp to move downward for more space, which is convenient for subsequent clamping of the sleeve body. By rotating the threaded rod, the two clamps squeeze the surface of the clamped sleeve body, and by rotating the thrust rod, the thrust rod drives the sleeve body to rotate, and the top of the connector is inserted through the latch teeth and the positioning block. By increasing the connection between the thrust rod and the sleeve body, slippage between the thrust rod and the sleeve body is prevented when the thrust rod is rotated.

[0028] Example

[0029] The technical solution in the embodiment of the present application effectively solves the problem that when the sleeve is fixed, the sleeve is disassembled by twisting it to one side by clamping the sleeve with a clamp. However, the surface of the sleeve is relatively smooth. When the clamp is clamped and subjected to force, the friction between the inner side of the clamp and the surface of the sleeve is insufficient, and it is easy to slip, which affects the disassembly progress of the sleeve. The overall idea is as follows:

[0030] In view of the problems existing in the prior art, the utility model provides a blast furnace cooling stave sleeve removal device, which comprises a thrust rod 1 and a sleeve body 11, a connector 12 is fixedly installed at the top end of the sleeve body 11, a fixing plate 13 is slidably installed at the top end of the thrust rod 1, a positioning block 15 is fixedly installed at the side end of the fixing plate 13, and two clamps 16 are slidably installed at the side end of the thrust rod 1 located below the positioning block 15, and by increasing the connection between the thrust rod 1 and the sleeve body 11, the thrust rod 1 is prevented from slipping with the sleeve body 11 when the thrust rod 1 is rotated;

[0031] The lower half of the positioning block 15 fits with the socket at the top of the connector 12, and the connection between the sleeve body 11 and the thrust rod 1 is increased. Two reset rods 14 are fixedly installed at the bottom end of the fixing plate 13, and the two reset rods 14 apply a downward pulling force to the fixing plate 13. A groove 17 is opened at the top of the thrust rod 1, and the end of the reset rod 14 is fixed inside the groove 17, and one end of the fixing plate 13 is pulled to move inside the groove 17. At least two latch teeth 22 are fixedly installed inside each clamp 16, and a fixing block 21 is fixedly installed on the outside of each clamp 16, so that the multiple latch teeth 22 squeeze the surface of the sleeve body 11, connect the thrust rod 1 with the sleeve body 11, and quickly fix the thrust rod 1;

[0032] The latch teeth 22 are subjected to the thrust of the clamp 16 and squeeze the surface of the sleeve body 11. The same threaded rod 24 is rotatably installed inside the two fixed blocks 21. A guide rod 19 is fixedly installed on the side end of each fixed block 21. The threaded rod 24 is rotated to allow the two fixed blocks 21 to move relative to each other. Two fixed frames 18 are fixedly installed on the side ends of the thrust rod 1. The two fixed frames 18 are staggered and fixed at the side ends of the thrust rod 1, and each fixed frame 18 is matched with the guide rod 19, so that the fixed plate 13 slides on the top end of the thrust rod 1, so that the thrust rod 1 drives the clamp 16 to move downward to create more space.

[0033] Working principle:

[0034] The first step is to move the thrust rod 1 when using it, so that the thrust rod 1 drives the two clamps 16 to move to the side end of the sleeve body 11, and the threaded rod 24 is rotated to rotate the threaded rod 24 inside the two fixed blocks 21, and the interior of the two fixed blocks 21 is provided with threads, but the threads inside the two fixed blocks 21 are designed in opposite directions, so that the threaded rod 24 is rotated to allow the two fixed blocks 21 to move to one end of each other, and the fixed block 21 drives the guide rod 19 to slide inside the fixed frame 18, and the guide rod 19 plays a role in stabilizing and guiding the fixed block 21, and at the same time, the spacing between the two clamps 16 is enlarged, and the sleeve body 11 is clamped between the two clamps 16, and the threaded rod 24 is rotated to allow the two fixed blocks 21 to slide against each other, and the spacing between the two clamps 16 is reduced, and at the same time, the two clamps 16 drive the clamping teeth 22 to move toward the surface of the sleeve body 11, so that a plurality of clamping teeth 22 squeeze the surface of the sleeve body 11, and the thrust rod 1 is connected to the sleeve body 11.

[0035] In the second step, the thrust rod 1 is fixed before the surface of the sleeve body 11, and the thrust rod 1 is moved so that the thrust rod 1 is at the upper end of the sleeve body 11. The thrust rod 1 is moved so that the thrust rod 1 is rotated at the top end of the sleeve body 11, and the positioning block 15 is aligned with the top end of the connector 12. The thrust rod 1 is pushed so that the sleeve body 11 drives the positioning block 15 to insert into the top end of the connector 12. At the same time, the thrust rod 1 is continued to be pushed so that the sleeve body 11 applies a reverse thrust to the positioning block 15, and the fixing plate 13 slides at the top end of the thrust rod 1. At the same time, the end of the fixing plate 13 slides inside the groove 17, and two reset rods 14 are fixedly installed at the end of the fixing plate 13. The two reset rods 14 connect the groove 17, and the fixing plate 13 The two reset rods 14 are stretched to allow the reset rods 14 to retract after being stressed, and at the same time, the two reset rods 14 pull the fixing plate 13 in opposite directions, so that the fixing plate 13 plays the role of connecting the thrust rod 1 and the sleeve body 11, and the fixing plate 13 is allowed to slide on the top end of the thrust rod 1, so that the thrust rod 1 drives the clamp 16 to move downward more space, which is convenient for the subsequent clamping of the sleeve body 11, and by rotating the threaded rod 24, the two clamps 16 squeeze and clamp the surface of the sleeve body 11, and by rotating the thrust rod 1, the thrust rod 1 drives the sleeve body 11 to rotate, and the top end of the connector 12 is inserted through the latch teeth 22 and the positioning block 15, and by increasing the connection between the thrust rod 1 and the sleeve body 11, slipping between the thrust rod 1 and the sleeve body 11 is prevented when the thrust rod 1 is rotated.

[0036] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
