Therefore, once an item is defined or described in one drawing, it will not be necessary to further specifically discuss and describe it in the description of the subsequent drawings.

[0023] Before understanding the present utility model, it should be clear that the roller table 2 is a commonly used conveying device in steel production. During the production process, due to the long running time of the intermediate billet on the roller table 2, the temperature drop of the intermediate billet is serious, especially at the head, tail and edges of the intermediate billet, resulting in unstable deformation or cracking at the edges during rolling, which seriously affects the metal mechanical properties of the produced steel. At the same time, it should also be clear that when the roller table 2 is under maintenance, the telescopic hydraulic cylinder 4 needs to be closed. Therefore, to prevent the closed telescopic hydraulic cylinder 4 from accidentally falling and injuring people due to other reasons such as hydraulic system leakage, component failure and misoperation, and to fully ensure the safety of maintenance staff, the present utility model provides an anti-tipping device applicable to the heat preservation cover. The anti-tipping device has been designed and evaluated by professionals, and the safety factor is greatly guaranteed.

[0024] It should also be clear that, as Figure 1 shown, the heat preservation cover 1 can heat-insulate the billet conveyed on the roller table 2 to improve the physical and chemical strength and internal tissue performance of the steel. The roller table 2 is installed on the roller table base 3, and a telescopic hydraulic cylinder 4 and a vertical plate 5 are also provided on the roller table base 3.

The heat preservation cover 1 is hinged on the vertical plate 5, and the telescopic hydraulic cylinder 4 can drive the heat preservation cover 1 to rotate around the hinge point. When the heat preservation cover 1 rotates to the first state, the heat preservation cover 1 encloses the roller table 2 to heat-insulate the billet conveyed on the roller table 2. When the heat preservation cover 1 rotates to the second state, the heat preservation cover 1 is away from the roller table 2.

[0027] As shown Figure 1 in the figure, the column 62 is a hollow square pipe, the pipe body of the square pipe is coated with paint, the connecting structure is a round-link chain 7, the connecting piece is a shackle 8, the contour shape of the shackle 8 is adapted to the round-link chain 7, and the heat preservation cover 1 can be connected and locked to the column 62 through the round-link chain 7 and the shackles 8 arranged at both ends of the round-link chain 7 to meet the requirements of quick disassembly or installation.

[0028] In the embodiment of the present utility model, the bottom plate 61 can be made of a steel plate with a thickness of 15-25 mm and is fixedly connected to the ground by expansion bolts.
