[0044] The slab continuous casting machine segment replacement device described in the utility model can be used to replace multiple segment 11 at the arc cooling section A of the slab continuous casting machine. The segment 12 to be replaced, which is pre-placed on the transfer table 22, is hoisted to the segment base 10 by a replacement vehicle 30 that can slide on the replacement vehicle frame 20. The above operation is performed multiple times until the installation of all the segment 11 is completed.

[0047] Firstly, the slab continuous casting machine has a connected arc cooling section A and a straight section B. The slab produced by casting can enter the arc cooling section A and the straight section B in sequence and can be cooled in the arc cooling section A.

[0048] The utility model only relates to the replacement of the fan-shaped segment 11 in the arc-shaped cooling segment A, and the structure of the straight segment B is not further introduced here. A fan-shaped segment base 10 is provided at the arc-shaped cooling segment A, and the fan-shaped segment base 10 is an arc-shaped support member as a whole, and its inner side surface is an arc-shaped surface.

The arc channels in the plurality of sector segments 11 installed adjacent to each other in sequence on the sector segment base 10 are connected in sequence, thereby forming a quarter-circle arc channel in the arc cooling section A of the slab continuous casting machine.

[0050] Furthermore, the replacement frame 20 is a support frame erected above the arc-shaped cooling section A and the straight section B, which is mainly composed of columns and track beams connected to form a frame structure as a whole, and is framed on the outside of the arc-shaped cooling section A and the straight section B.

[0051] The replacement frame 20 is provided with a first guide rail 21 extending along the conveying direction of the straight section B, and one end of the first guide rail 21 can cover the arc cooling section A. The end of the replacement frame 20 away from the arc cooling section A is provided with a transfer table 22, and the transfer table 22 can place the sector 12 to be replaced.

[0052] The replacement vehicle 30 slidably arranged on the first guide rail 21 can slide along the first guide rail 21, and then move between the turntable 22 and the arc-shaped cooling section A, so as to move the sector segment 12 to be replaced from the turntable 22 to the arc-shaped cooling section A, and then install the sector segment 12 to be replaced on the sector base 10.

[0054] The structure and technical effects of the preferred implementation of the slab continuous casting machine sector replacement device of the utility model will be further described below.

[0055] According to one embodiment of the present utility model, Figure 1 As shown, the slab continuous casting machine sector segment replacement device also includes: a plurality of second guide rails 41, which are respectively arranged at the installation positions of the plurality of sector segments 11 on the sector segment base 10, and the second guide rails 41 extend along the radial direction of the arc-shaped cooling segment A, and the plurality of second guide rails 41 can be radially docked with the swing arm 31 on the replacement vehicle 30.

[0056] In this embodiment, the cooperation between the second guide rail 41 and the swing arm 31 can facilitate the segment 12 to be replaced to be clamped into the relative position in the segment base 10; when the replacement vehicle 30 drives the segment 12 to be replaced suspended thereon to move to the top of the segment base 10, the swing arm 31 is rotated to drive the segment 12 to be replaced to rotate around the rotation axis until the swing arm 31 docks with the second guide rail 41 at the installation position, at which time, the hook 32 on the replacement vehicle 30 is released, and the segment 12 to be replaced can slide along the swing arm 31 and the second guide rail 41 to the relative position on the segment base 10. For the installation operation at different positions in the segment base 10, it is only necessary to control the rotation angle of the swing arm 31 to dock with the second guide rail 41 at different angles, thereby realizing the installation of multiple segments 12 to be replaced.

[0057] Specifically, Figure 2 As shown, a guide rail frame 40 is provided on the segment base 10, and a second guide rail 41 is fixed on the guide rail frame 40; the guide rail frame 40 is used to support the second guide rail 41, enhance its structural strength, and prevent the second guide rail 41 from being deformed due to the load generated by the segment 12 to be replaced. A second guide rail 41 extending in the radial direction is provided at the corresponding position of each positioning seat 14 of the segment base 10, and multiple second guide rails 41 all point to the center position of the arc cooling segment A; when the replacement vehicle 30 is located above the segment base 10, the rotation axis of its swing arm 31 coincides with the above center position, so that the swing arm 31 can be radially docked with all the second guide rails 41 during the rotation process.

[0058] According to one embodiment of the present utility model, Figure 1 As shown, the side of the segment 12 to be replaced is provided with a guide wheel 13, and when the swing arm 31 and the second guide rail 41 are connected, the segment 12 to be replaced hung on the hook 32 slides along the second guide rail 41 to the segment base 10 and is installed in place. The guide wheel 13 provided on the side of the segment 12 to be replaced can facilitate its sliding on the second guide rail 41 and the swing arm 31, so that it can smoothly slide into the segment base 10 and be installed in place in the unhooked state.

[0059] Preferably, a second guide rail 41 is provided on both sides of the installation position of each segment 11 on the segment base 10, and a guide wheel 13 is provided on both sides of the segment 12 to be replaced. The second guide rail 41 and the guide wheel 13 are provided on both sides of the segment 12 to be replaced, so that the force of the segment 12 to be replaced is balanced during the sliding process, and the position deviation thereof is avoided, which requires manual adjustment by the operator.

[0060] According to one embodiment of the present utility model, Figure 2 As shown, a driving member 50 for driving the driving roller 15 in the sector segment 11 to rotate is provided above the second guide rail 41. After the sector segment 12 to be replaced is clamped into the positioning seat 14, the driving member 50 is drivingly connected to the sector segment 12 to be replaced. The driving member 50 is used to provide power to the driving roller 15 in the sector segment 11, so as to achieve continuous pulling with the slab, so that it can stably pass through the arc-shaped cooling section A for cooling.

[0061] According to one embodiment of the present utility model, Figure 2 As shown, steam exhaust pipes 51 are provided on both sides of the sector base 10; the steam exhaust pipes 51 are mainly used to exhaust the steam generated by the cooling of the slab to outside the factory.

[0062] According to one embodiment of the utility model, the slab continuous casting machine segment replacement device further includes a crane for hoisting the to-be-replaced segment 12 onto the turntable 22; the crane may be an overhead crane in a workshop. The to-be-replaced segment 12 is pre-hoisted by the crane and placed on the turntable 22. Since the positioning and installation process of the replacement segment 11 is realized by the replacement vehicle 30, the to-be-replaced segment 12 placed on the turntable 22 does not have corresponding angle and posture requirements, so the hoisting and installation process is relatively simple.
