Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0031] The main control for stage machinery braking is usually a motor or hydraulic system. When a larger braking force is required, some auxiliary buffer devices will be used.

[0032] Specifically, such as Figures 1-3 As shown in Embodiment 1, a novel stage machinery buffer device includes multiple vertically arranged upper and lower guide rails 1, on which stage moving parts 2 are slidably installed, and multiple buffer devices are arranged between the bottom of the stage moving parts 2 and the stage floor.

[0033] Specifically, in this embodiment, the upper and lower guide rails 1 are sliding guide rails. The sliding guide rail includes a vertically installed guide rail seat. A vertical groove is opened in the guide rail seat. The groove can be a dovetail groove, a T-shaped groove, or other structures. A slider is slidably connected in the groove. The slider is fixedly connected to the stage moving part 2 so that the stage moving part 2 can slide up and down along the guide rail.

[0034] The stage floor is fixed with a steel structure and / or a pre-embedded structure 16, which is a steel structure plate pre-embedded in the ground.

[0035] A static component connecting seat 15 is installed on the steel structure and / or the embedded structure 16. The static component connecting seat 15 is a frame-shaped steel structure seat.

[0036] A permanent magnet 14 is fixed to the top of the stationary component connector 15. The fixing methods are as follows: embedded installation, a groove is cut in the platform, the magnet is embedded and then filled with silicone or potting compound, which can both fix it and prevent shock. Fixing with a clamp is also possible, using a non-magnetic metal (aluminum, copper) or plastic clamp to fix the magnet by lateral pressure, avoiding direct contact with magnetic field sensitive areas. Adhesive fixing is also possible, using epoxy resin or acrylic structural adhesive. The permanent magnet 14 is a perforated strong magnet. Threaded holes are made in the stationary component connector 15 and the moving component connector 13, and then the permanent magnet 14 is installed on the stationary component connector 15 and the moving component connector 13 by tightening bolts.

[0037] A moving part connecting seat 13 is installed at the bottom of the moving part 2 of the stage. The moving part connecting seat 13 and the stationary part connecting seat 15 have the same structure. They are both rectangular frame steel structures. In this embodiment, they are fixedly connected by welding.

[0038] A permanent magnet 14 is installed at the bottom of the moving part connector 13, and the moving part connector 13 is positioned directly opposite the stationary part connector 15. The permanent magnets 14 of the moving part connector 13 and the stationary part connector 15 are arranged with the same pole facing each other to provide repulsive force.

[0039] The stage floor surface is provided with a decorative surface 3, and the decorative surface 3 at the static component connecting seat 15 is provided with a groove to reduce the thickness of the decorative surface 3 at the top of the static component connecting seat 15.

[0040] Specifically, in this embodiment, decorative surface 3 is a ceramic floor.

[0041] The permanent magnet is smaller than the size of the stationary component connector 15 and the moving component connector 13.

[0042] like Figures 4-5 As shown, in Embodiment 2, the difference from Embodiment 1 is that a spring seat 8 is fixed inside the stage floor. The spring seat 8 includes a bottom plate 5, a cylindrical body 6 is fixed on the bottom plate 5, a limit ring 10 is fixed on the top of the cylindrical body 6, a spring 8 is fixed inside the cylindrical body 6, and a pressure cap 9 is fixed on the top of the spring 8. The pressure cap 9 is a cylindrical body 6, and the pressure cap 9 is upside down on the top of the spring 8, with the circular wall of the pressure cap 9 in contact with the inner wall of the cylindrical body 6.

[0043] The size of the pressure cap 9 is adapted to the inner diameter of the cylindrical body 6. The bottom of the stage moving part 2 is equipped with a pin 4. The size of the pin 4 is adapted to the hole diameter of the limiting ring 10. The pin 4 is directly opposite the inner hole of the limiting ring 10.

[0044] The top of the pressure cap 9 is fixed with a boss 11. The size of the boss 11 is adapted to the inner diameter of the limiting ring 10. When the pin 4 is not pressed down, the pressure cap 9 moves upward under the elastic force of the spring 8. At this time, the top of the pressure cap 9 contacts the limiting ring 10, and the boss 11 extends into the middle through hole of the limiting ring 10. The surface of the boss 11 is flush with the top of the limiting ring 10. The same pattern as the decorative surface 3 is printed on the surface of the limiting ring 10 and the boss 11 to maintain the integrity of the decorative surface 3.

[0045] The cylindrical body 6 is provided with multiple reinforcing plates 7 on its side. The reinforcing plates 7 are trapezoidal plates that are narrower at the top and wider at the bottom to enhance the stability between the cylindrical body 6 and the bottom plate 5.

[0046] The latch 4 and the movable part connecting seat 13 are both mounted on the load bearing structure 12 of the movable stage part 2, so that the load in the buffering process can be shared to the load bearing structure 12, and in the embodiment, the load bearing structure 12 of the movable stage part 2 is a steel structure framework of the movable stage part 2, and the sliding block is fixedly connected with the steel structure framework.
