Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of steelmaking continuous casting straightening machines, and mainly relates to a tool for adjusting the spacing of steelmaking continuous casting straightening machines. Background Art
[0002] The continuous casting straightening machine is a crucial piece of equipment in the steelmaking process. It is primarily used in continuous casting production lines to stretch and straighten the ingots fresh from the mold. Multiple straightening machines are typically installed, with adjacent straightening machines positioned in parallel to ensure the straightness and dimensional accuracy of the ingots, meeting the requirements for subsequent processing and use.
[0003] However, during the installation of the steelmaking continuous casting straightening machine, there will be problems with improper base installation, which may cause the machine to be offset from the adjacent steelmaking continuous casting straightening machine during operation. In addition, since the steelmaking continuous casting straightening machine operates in a high temperature and high load environment, these extreme conditions will also cause component wear or deformation, which in turn causes the steelmaking continuous casting straightening machine to be offset. The above situations will cause quality problems such as bending and deformation of the ingot, resulting in reduced ingot quality.
[0004] Currently, the offset steelmaking continuous casting straightening machine is adjusted manually using a jack. Due to the heavy weight of the jack, two people are required to work together during the adjustment. In addition, when the working stroke of the jack does not meet the use requirements, an extension rod needs to be used to increase the length of the jack, which is cumbersome and wastes manpower. Utility Model Content
[0005] The utility model provides a tool for adjusting the spacing of a straightening machine in steelmaking and continuous casting, so as to solve the problem of wasting manpower in the prior art.
[0006] In order to solve the above problems, the present invention adopts the following technical solutions:

The end of the push rod away from the fixed clamping seat is provided with a push portion for pushing the shifted straightening machine to align it with the unshifted straightening machine.
[0008] Beneficial effect: When a straightening machine is offset, the fixed clamp is clamped on the adjacent non-offset straightening machine, and the pushing part points in the direction of the offset straightening machine. The staff holds the handheld part with one hand and rotates the hexagonal nut with a wrench with the other hand to push the offset straightening machine with the pushing part to align the offset straightening machine with the non-offset straightening machine. This tool is simple to operate, light in weight, and can be operated by one person, solving the problem of waste of manpower in the existing technology.
[0009] Furthermore, the fixed clamping seat is rectangular, and is provided with a U-shaped clamping groove with a notch facing downwards for clamping the fixed clamping seat on the non-deflected tensioning and straightening machine.
[0010] Beneficial effect: The fixed clamping seat is clamped on the non-deflected straightening machine through the U-shaped clamping groove, preventing the fixed clamping seat from moving left and right when the push rod is rotated, affecting the adjustment of the straightening machine.
[0011] Furthermore, the fixed base is provided with a threaded hole extending in the left-right direction, and the push rod is provided with a circle of external threads adapted to the threaded hole.
[0012] Beneficial effects: the push rod and the fixed base are directly threaded together, which simplifies the structure and is easy to operate.

[0025] The embodiment of the tool for adjusting the spacing of the straightening machine for continuous casting of steelmaking provided by the utility model:
[0026] like Figure 1 As shown, the tool for adjusting the spacing of the straightening machine for continuous casting steelmaking includes a fixed clamping base 2 and a push rod. In this embodiment, for the convenience of description, the length direction of the fixed clamping base 2 is defined as the left-right direction, the width direction of the fixed clamping base 2 is defined as the front-back direction, and the height direction of the fixed clamping base 2 is defined as the up-down direction.
[0027] like Figure 1 and Figure 2 As shown, the fixed base 2 is rectangular and extends in a horizontal direction. The fixed base 2 is provided with a threaded hole extending in the horizontal direction. The push rod is provided with a circle of external threads that match the threaded hole. The push rod is directly threadedly connected to the fixed base 2, simplifying the structure and facilitating operation. The fixed base 2 also has a U-shaped slot 1 with a notch facing downward for securing the fixed base 2 to the undeflected straightening machine. The threaded hole is connected to the U-shaped slot 1. The fixed base 2 also has a handle 3 extending in an upward and downward direction. Since the deflected straightening machine is pushed at a relatively high height, the operator grasps the handle 3 at a certain height to push the tool to the corresponding position, which is more convenient and prevents the fixed base 2 from rotating when the push rod rotates. The handle 3 is elliptical in shape, which provides a tighter fit for the hand, preventing injury and making it more comfortable to use. In other embodiments, the handle 3 can also be shaped in other ways, such as circular, as long as it ensures a comfortable grip for the user.
[0028] like Figure 1As shown, the push rod includes a threaded section 4, a rotating section, a connecting section 6 and a pushing section connected in sequence from left to right. The external thread is located on the threaded section 4. A hexagonal nut 5 coaxial with the push rod is fixed on the rotating section. The staff can use a wrench to rotate the hexagonal nut 5 to move the push rod, which is simple to operate and saves manpower. The connecting section 6 is a light column, and a pushing part 7 is provided on the pushing section. The top of the pushing part 7 is arc-shaped to prevent the center of the pushing part 7 from deviating when the push rod rotates. The connecting section 6 connects the rotating section and the pushing section.
[0029] The working process of this utility model is as follows:
[0030] When a straightening machine is offset, the fixed clamping base 2 is clamped on the adjacent non-offset straightening machine, and the pushing part 7 points to the direction of the offset straightening machine. The staff holds the hand-held part 3 with one hand and uses a wrench to turn the hexagonal nut 5 to move the pushing rod to the right. The pushing part 7 pushes the offset straightening machine to align it with the non-offset straightening machine. This tool is simple to operate, light in weight, and can be operated by one person, solving the problem of waste of manpower in the existing technology.
