DETAILED DESCRIPTION
[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application. Example
[0017] like Figure 1 , Figure 2 A ground protection device for heavy-duty movable grandstand conversion and translation includes steel guard plate 4 and countersunk bolts 4.5. The steel guard plate 4 is laid according to the travel route of the multi-wheeled auxiliary pallet truck 3. Adjacent steel guard plates 4 are assembled and connected by countersunk bolts 4.5. The countersunk bolts 4.5 are embedded in the steel guard plate 4, so that the connected steel guard plates 4 form a flat surface.
[0018] The aforementioned heavy-duty movable grandstand conversion and translation ground protection device has a tongue and groove joint 4.4 on the edge of the steel guard plate 4, so that adjacent steel guard plates 4 can be overlapped through the tongue and groove joint 4.4 and connected to each other by countersunk bolts 4.5.
[0019] The aforementioned heavy-duty movable grandstand conversion and translation ground protection device has countersunk holes at the tongue and groove of the steel guard plate 4. The countersunk holes are used to install countersunk bolts 4.5. The countersunk bolts 4.5 are embedded in the countersunk holes, so that the adjacent steel guard plates 4 after connection form a flat plane.
[0020] The aforementioned ground protection device for the conversion and translation of heavy-duty movable grandstands also includes ear plates 4.1, connecting plates 4.2, and mounting bolts 4.3. The ear plates 4.1 are arranged on both sides of the steel guard plate 4 and located at the splicing point of the steel guard plate 4. The ear plates 4.1 of adjacent steel guard plates 4 are connected by the connecting plates 4.2 and the mounting bolts 4.3. Example
[0021] Example 2 demonstrates the switching between athletics and football viewing modes in a stadium's movable stands, as described in Example 1; Figure 3 :
[0022] A method for switching stadium activity stands between track and field mode and football mode:
[0023] The front support leg 1.1 of the movable grandstand 1 is placed on the pallet trolley 3. The middle support leg of the movable grandstand 1 is raised, and the steel wheel trolley 5 is installed under the outermost support leg. The steel wheel trolley 5 can move freely in the horizontal direction. When the movable grandstand 1 is moved to switch modes, the pallet trolley 3 pulls the movable grandstand 1 to the designated position, and the flat grandstand 2 is raised from the original position of the movable grandstand 1, realizing the expansion of the grandstand towards the center of the stadium, completing the conversion from track and field mode to football mode.
[0024] During the conversion process, steel guardrails 4 need to be laid along the travel route of the pallet truck 3 to protect the plastic track.
[0025] Furthermore, a method for switching between football and track and field viewing modes in a stadium's event stands:
[0026] The flat grandstand 2 is lowered, and the pallet truck 3 pulls the movable grandstand 1 back to the edge of the field. The pallet truck 3 is removed from the movable grandstand 1, the steel guard plate 4 is removed and stacked in the storage position (at this time, the ear plate 4.1 also serves as a hoisting hole), exposing the track and field track, and completing the conversion from football mode to track and field mode.
[0027] In the above process, the steel protective plate 4 needs to be segmented to facilitate transportation and installation. The width of each segment 4 is the same as or 10cm to 30cm wider than the pallet truck 3, ensuring that the pallet truck always travels within the steel protective plate area. The segment lengths of the steel protective plate 4 are 2m, 3m, or 4m, with adjustable sections at the ends of varying lengths depending on actual needs. The required thickness of the steel protective plate 4 is calculated using finite element analysis software. The segments of the steel protective plate 4 are connected by mounting bolts to prevent misalignment when the pallet truck 4 travels on it.
[0028] Furthermore, when installing the connecting plate 4.2, it is necessary to clear away debris and gravel from the ground to be laid, ensuring that the steel guard plate 4 is tightly adhered to the ground after installation. Then, place the steel guard plate 4 to be connected at the front end of the already fixed steel guard plate 4 segment, aligning the edges of the two steel guard plates 4 and ensuring there are no gaps between them. At this point, the ear plate 4.1 of the steel guard plate to be connected is also aligned with the already fixed steel guard plate 4. Next, place the connecting plate 4.2 on the outside of the ear plate 4.1 (near the edge of the steel guard plate) and tighten the four mounting bolts 4.3, ensuring there are no gaps between the ear plate 4.1 and the connecting plate 4.2. The other connecting plate is fixed in the same way. The steel guard plate connection is now complete, and the installation and connection of the next steel guard plate is continued using the same method.
[0029] Furthermore, when connecting the tongue and groove joints 4.4, care should be taken to ensure that the tongue and groove joints 4.4 of adjacent steel guard plates 4 do not conflict; this facilitates the laying and adjustment of the steel pads and guard plates to be connected. After the steel guard plates 4 to be connected are laid, the tongue and groove joints 4.4 of the steel guard plates to be connected should be aligned with the fixed steel guard plates 4, ensuring that the bolt holes of the tongue and groove joints 4.4 of the steel guard plates to be connected correspond one-to-one with the bolt holes of the fixed steel guard plates 4. Finally, the countersunk bolts 4.5 should be fully screwed into the bolt holes, ensuring that the surface of the steel guard plate 4 is basically flat and that the countersunk bolts 4.5 do not protrude significantly.
[0030] In the above process, support columns can also be set as needed. The support columns are set at the bottom of the steel guard plate 4. When there is a height difference between the steel guard plate 4 and the stadium floor, the steel guard plate 4 can be kept horizontal by setting support columns between the steel guard plate 4 and the stadium floor.
[0031] As can be seen from the above embodiments, the floor covering component proposed in this utility model can protect the plastic floor from damage caused by the operation of the mode conversion machinery during the conversion of the movable heavy-duty grandstand in the stadium between multiple modes (such as track and field mode and football mode). At the same time, it can also ensure the safety of the movable heavy-duty grandstand during the mode conversion process and improve the conversion efficiency of the grandstand.
[0032] The above are merely embodiments provided in this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
