Specifically, the hollow horizontal frame body 1 is a shell structure with a hollow interior and openings at both ends, and it is arranged horizontally, that is, as Figure 2 shown, the opening arrangement direction is vertically arranged, that is, the front and rear sides are open, and the left and right ends are closed, and it can be used to connect other components such as a trailing device (not shown in the figure) and / or a base cross beam 20. Among them, the hollow part serves as the hollow installation space. As Figure 1As shown, the overall equipment for rotating and hoisting the rolling mill housing may be provided with four support bases 10, and the four support bases 10 may be arranged at the four corners to support the four support columns 6 respectively; moreover, the four support bases 10 are connected by four base cross beams 20 to form an integral base support body by enclosing. In this embodiment, the trailing device may be arranged on the left or right side of the left two support bases 10 and connected to the two support bases 10 respectively, so that the integral base support body moves along the track under the action of the trailing device, and then drives the support column to move. The four support columns 6 can support and fix the rolling mill housing, so as to realize the hoisting and rotation of the supported rolling mill housing through the hoisting and rotation of the support columns 6 and the integral base support body. Among them, several pairs of track limit blocks 7 are provided at the bottom of the hollow horizontal frame body 1 for being clamped on both sides of the track to guide the sliding of the hollow horizontal frame body 1 along the track; in this embodiment, three pairs of track limit blocks 7 are taken as an example for illustration, as Figure 6 shown, the three pairs of track limit blocks 7 are arranged in a straight line at the bottom of the hollow horizontal frame body 1; preferably, as Figure 5 and Figure 7 shown, chamfers can be provided at the bottom end of the track limit block 7 and the bottom end of the side of the hollow horizontal frame body 1 to control the offset range when the hollow horizontal frame body 1 moves horizontally and ensure that the hollow horizontal frame body 1 will not get stuck on the track. Among them, the distance between the two track limit blocks 7 in each pair of track limit blocks 7 is greater than the width of the track, for example, 12 mm larger than the track width, to ensure smooth sliding.

[0030] At least two transversely extending rib plates 2 arranged at intervals are provided inside the hollow horizontal frame body 1. The transversely extending rib plates 2 are arranged along the length direction of the hollow horizontal frame body 1, and each transversely extending rib plate 2 has a concave structure, and an upper support column support layer is formed by enclosing between the transversely extending rib plate 2 and the top wall of the hollow horizontal frame body 1. Specifically, in this embodiment, three transversely extending rib plates 2 are taken as an example for illustration. The three transversely extending rib plates 2 are arranged side by side and at intervals along the width direction of the hollow horizontal frame body 1 (such as the vertical direction shown in Figure 9 and Figure 10 to ensure the stability of the support for the corresponding components. Each transversely extending rib plate 2 is vertically arranged inside the hollow horizontal frame body 1, and the top end and the bottom end are respectively connected to the inner top wall and the inner bottom wall of the hollow horizontal frame body 1; moreover, the transversely extending rib plate 2 can be of a concave structure, and both ends are connected from the bottom wall of the hollow horizontal frame body 1 to the top wall of the hollow horizontal frame body 1, so that there is a certain installation space in the middle of the top of the hollow horizontal frame body 1, that is, the upper support column support layer, that is, the middle part supports the column support assembly 3.
