Background
The rotary floor height adjusting device is one of important components of the rotary floor, provides reliable support for the rotary floor during rotation, and ensures that the rotary floor is stable, safe, reliable and free from abnormal sound during the rotation process. At present, most of rotary floor height adjusting devices commonly used in China adopt roller type height adjusting devices.
By adopting the rotary floor height adjusting device with the structure, the mounting bolts of the roller assemblies need to be loosened during adjustment, and the adjustment of the rotary floor in the height direction is realized by increasing or decreasing the number of the adjusting pads below the ball assemblies; when the installation radius of the height adjusting device of the rotary floor is too small, the roller assembly can generate clamping stagnation and inflexible rotation when rotating. In addition, when the height of the height adjusting device of the rotary floor is too high, the derailment phenomenon of the height adjusting device can occur in the rotating process of the rotary floor. Therefore, it is necessary to design a new rotary floor height adjusting device.

Detailed Description
In order to make the objects, contents and advantages of the present invention clearer, the following detailed description of the embodiments of the present invention will be made in conjunction with the accompanying drawings and examples.
The present embodiment provides a rotary floor height adjustment device, which has a structure as shown in fig. 1, and includes an adjustment structure and an anti-derailing structure.
As shown in fig. 2, the adjustment structure includes an upper mounting sleeve 4, a locknut 5, a stud 6, and a mounting base 7. Wherein, stud 6 both ends have the external screw thread respectively, and two locknut 5 are installed respectively at stud 6's both ends, and the threaded hole of installing the lower extreme of sleeve 4 is twisted into to the one end of the stud 6 of installing locknut 5, and the threaded hole of installing the upper end of base 7 is twisted into to the other end of stud 6. When the height needs to be adjusted, the locknuts 5 on the two sides of the stud 6 are properly loosened, the outer hexagon in the middle of the stud 6 is rotated by a tool, the stud 6 can simultaneously rotate in the threaded holes in the upper mounting sleeve 4 and the mounting base 7, the adjustment in the height direction is realized, and the locknuts 5 on the two ends of the stud 6 are screwed when the height is adjusted to a proper position.
As shown in fig. 3, the derailing prevention structure includes a rotation rail 2 and a ball assembly 3. Wherein, the base welding of ball assembly 3 is at the top dead end of last installation sleeve 4, and the ball card of ball assembly 3 lower part rolls in the semicircular spacing inslot on rotating track 2, and the top welding of rotating track 2 is in the bottom of rotating floor 1. When the rotating floor 1 rotates, the rotating track 2 is driven to rotate together, and meanwhile, the balls of the ball assembly 3 rotate in the semicircular limiting grooves of the rotating track 2.
