[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3This embodiment provides a technical solution: a lifting device for hot online lifting of float glass tin bath, including a top cover 1, a steel ruler 7 is provided on the side of the top cover 1, a galvanized pipe 5 is provided between the steel rulers 7, a hook 6 is provided at the end of the galvanized pipe 5 away from the top cover 1, a plumb bob 12 is suspended on the hook 6, and a grid paper 4 is provided under the plumb bob 12.

[0020] like Figure 1-3 As shown, when lifting the top cover, it is connected to the trolley via the suspension screw 11, and then the plumb bob 12 is suspended on the hook 6. Graph paper 4 is set on the lower side of the plumb bob 12, and a level instrument is set up in the high temperature, medium temperature and low temperature areas on both sides of the top cover 1. The steel ruler 7 on the top cover 1 is observed through the level instrument. During the lifting process, the steel ruler 7 moves upward. By observing the difference between the crosshair on the level instrument and the scale line on the steel ruler 7 before and after the lifting, the lifting height of the top cover 1 is calculated. When lifting the top cover 1, the rotating frame 10 is rotated. The rotating frame 10 rotates 1 / 12 turn each time, so that the top cover 1 is lifted upward by 0.58mm. The four rotating frames 10 on the upper side of the top cover 1 rotate once, so that the top cover 1 can be lifted upward stably as a whole, ensuring the accuracy and stability of the lifting. If the top cover 1 shifts horizontally during the lifting process, the position of the plumb bob 12 corresponding to the lower graph paper will change, and the horizontal displacement of the plumb bob 12 can be observed.

[0021] The top cover 1 has threaded rods 9 at the four corners of its upper side, and a scale plate 8 is fitted on the threaded rods 9.

[0022] A rotating frame 10 is threadedly connected to the threaded rod 9, and a suspension screw 11 is threaded through the upper part of the rotating frame 10.

[0023] A side seal 2 is provided on the lower side of the top cover 1, and a bottom shell 3 is provided on the lower side of the side seal 2.

[0024] The galvanized pipe 5 is welded to the top cover 1, the top cover 1 is hinged to the threaded rod 9, and the dial 8 is fixedly connected to the threaded rod 9.

[0025] The rotating frame 10 is connected to the suspension screw 11 by a thread, and the steel ruler 7 is fixedly connected to the top cover 1. The steel ruler 7 measures a length of 300mm.

[0026] The working principle of the lifting device for hot online lifting of float glass tin bath provided by this utility model is as follows: Figures 1-3As shown, when lifting the top cover, it is connected to the trolley via the suspension screw 11. Then, the plumb bob 12 is suspended on the hook 6. Graph paper 4 is placed under the plumb bob 12. Level instruments are set up in the high-temperature, medium-temperature, and low-temperature areas on both sides of the top cover 1. The steel ruler 7 on the top cover 1 is observed through the level instruments. During the lifting process, the steel ruler 7 moves upward. By observing the difference between the crosshair on the level instrument and the scale line on the steel ruler 7 before and after the lifting, the lifting height of the top cover 1 is calculated. When lifting the top cover 1, the rotating frame 10 is rotated. Each rotation of the rotating frame 10 is 1 / 12 of a turn, corresponding to a 30-degree rotation on the scale 8. This allows for precise control and adjustment of the rotation of the rotating frame 10, resulting in the top cover 1 being raised by 0.58mm. The four rotating frames 10 on the upper side of the top cover 1 rotate at one time, allowing the top cover 1 to be raised stably as a whole, ensuring the accuracy and stability of the lifting. If the top cover 1 shifts horizontally during the lifting process, the position of the plumb bob 12 corresponding to the grid paper on the lower side will change, thus allowing the horizontal displacement of the plumb bob 12 to be observed.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
