[0029] Continue to refer Figure 1 and Figure 2 It can be seen that a counterweight 3 that can move up and down is provided on one side of the vertical section 21 , and the counterweight 3 is connected to a cylinder 5 via a steel wire rope 4 , wherein the steel wire rope 4 is arranged along the bracket 2 and placed on two fixed pulleys 25 .

[0030] The utility model is also provided with a first driving mechanism 6 for driving the counterweight 3 to move up and down. The first driving mechanism 6 can be further referred to in the specific arrangement. Figure 1 and Figure 2 ,according to Figure 1 and Figure 2 It can be seen that the first driving mechanism 6 includes a slide groove 61 vertically opened on one side of the vertical section 21, the slide groove 61 is slidably connected to a slider 62, and one end of the slider 62 located outside the slide groove 61 is fixedly connected to the counterweight 3; continue to refer to Figure 1 and Figure 2 The vertical section 21 is located at the top of the slide groove 61 and is fixedly connected to a horizontal bearing seat 66. The bearing seat 66 is rotatably connected to a vertically arranged threaded rod 63 through a second bearing. The top of the threaded rod 63 is fixedly connected to the inner ring of the second bearing, and the bottom end of the threaded rod 63 passes downward through the slider 62 and is threadedly connected to the slider 62.

[0031] In order to facilitate the rotation of the threaded rod 63 in the present invention, reference can be made to Figure 3 ,according to Figure 3 It can be seen that the bottom end of the threaded rod 63 is fixedly sleeved with a first gear 64, and the vertical section 21 is fixedly sleeved with a second gear 65 meshing with the first gear 64 at a position corresponding to the first gear 64. By driving the second gear 65 to rotate, the bracket 2 can be rotated, and the second gear 65 can drive the first gear 64 and the threaded rod 63 to rotate at the same time. The rotating threaded rod 63 drives the slider 62 to drive the counterweight 3 to move up and down along the slide slot 61, thereby moving the cylinder 5 up and down; continue to refer to Figure 3 It can be seen that a first bearing 11 is provided on the base 1 , and the bottom of the vertical section 21 is fixedly connected to the inner ring of the first bearing 11 .

The second driving mechanism 7 includes a first driving motor 71 . A driving gear 72 meshing with the second gear 65 is fixedly sleeved on the output shaft of the first driving motor 71 .

[0033] The working principle of the cylinder 5 moving bracket 2 for hot repairing the steel ladle is as follows: when the cylinder 5 is not in use, the driving gear 72 can be rotated by the first driving motor 71, and the rotating driving gear 72 rotates the second gear 65 and the bracket 2, and the rotating bracket 2 can rotate the cylinder 5 to one side of the steel ladle, so as to facilitate the movement of the steel ladle; the second gear 65 can drive the first gear 64 and the threaded rod 63 to rotate while rotating, and the rotating threaded rod 63 drives the slider 62 to drive the counterweight 3 to move downward along the slide 61, so as to move the cylinder 5 upward. Therefore, while the bracket 2 rotates, the cylinder 5 moves upward, so that the cylinder 5 is away from the steel ladle, which is convenient for the subsequent movement of the steel ladle.

[0034] When it is necessary to use the cylinder 5 to close the water outlet slider of the ladle, the first driving motor 71 causes the driving gear 72 to rotate in the opposite direction, and the reversely rotating driving gear 72 causes the second gear 65 and the bracket 2 to rotate in the opposite direction until the cylinder 5 and the water outlet mechanism of the ladle are located on the same vertical plane; the second gear 65 can drive the first gear 64 and the threaded rod 63 to rotate in the opposite direction while rotating in the opposite direction, and the reversely rotating threaded rod 63 causes the slider 62 to drive the counterweight 3 to move upward along the slide groove 61, thereby causing the cylinder 5 to move downward, and when the cylinder 5 moves to the same vertical plane as the water outlet mechanism of the ladle, the cylinder 5 just contacts the water outlet mechanism of the ladle, and then the cylinder 5 is installed on the water outlet mechanism, so that the water outlet slider of the ladle can be closed conveniently by the cylinder 5.

Thus, while the bracket 2 rotates, the cylinder 5 moves upward, so that the cylinder 5 is away from the ladle, which is convenient for the subsequent movement of the ladle.

[0038] When it is necessary to use the cylinder 5 to close the water outlet slider of the ladle, the second drive motor causes the second drive gear 72 to rotate in the opposite direction, and the second pulley rotating in the opposite direction causes the first pulley, the second gear 65 and the bracket 2 to rotate in the opposite direction until the cylinder 5 and the water outlet mechanism of the ladle are located on the same vertical plane; the second gear 65 can drive the first gear 64 and the threaded rod 63 to rotate in the opposite direction while rotating in the opposite direction, and the threaded rod 63 rotating in the opposite direction causes the slider 62 to drive the counterweight 3 to move upward along the slide groove 61, thereby moving the cylinder 5 downward, and when the cylinder 5 moves to the same vertical plane as the water outlet mechanism of the ladle, the cylinder 5 just contacts the water outlet mechanism of the ladle, and then the cylinder 5 is installed on the water outlet mechanism, so that the water outlet slider of the ladle can be closed by the cylinder 5.
