[0043] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0044] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0045] Existing technologies mainly use integrated telescopic platforms, whose length and width are fixed and can only be retracted and extended, making it impossible to freely adjust them according to the needs of different scenarios. In addition, disassembling, assembling, and transporting integrated telescopic platforms requires a lot of manpower and time, increasing the inconvenience of use.

[0046] This application provides a detachable telescopic platform device to improve the flexibility and portability of the telescopic platform device, and to facilitate free adjustment according to the needs of different scenarios.

[0047] Please refer to Figure 1 , Figure 2 and Figure 3A detachable telescopic platform device includes: a static truss 1, fixed to the installation environment for supporting and securing the telescopic platform device; a movable truss 2, comprising multiple sets of telescopic platform assemblies movable along the telescopic direction; a drive device 3, connected to the static truss 1 and used to drive the movable truss 2 to retract into the range of the static truss 1; the telescopic platform assembly includes: a stepped platform 21; a horizontal support frame 22, horizontally arranged to support the stepped platform 21; a vertical support frame 23, the upper end of which is fixed to and supports the horizontal support frame 22; and a base support frame 2. 4. The support is horizontally set and positioned on the same side as the support crossbar 22 and the support vertical bar 23. The lower end of the support vertical bar 23 is fixed to the support base 24. Multiple moving wheel assemblies 25 are distributed at the lower end of the support base 24, and the axis of the moving wheel assembly 25 is perpendicular to the telescopic direction of the telescopic platform equipment. The support vertical bars 23 of two adjacent telescopic platform assemblies have different heights, so that the support crossbar 22, the support vertical bar 23 and the support base 24 form a storage space 26 with a lateral notch for stacking multiple telescopic platform assemblies.

[0048] In this embodiment, the static truss 1 and the moving truss 2 are designed separately. The static truss 1 is fixed to the site, while the moving truss 2 achieves telescopic movement via a drive device 3. The two are quickly connected through modular components. Specifically, the static truss 1 can be a high-strength steel frame, fixed to the ground or mounting base by anchor bolts or welding, serving as the static support foundation for the equipment. In this embodiment, the static truss 1 is configured as a stepped structure frame made of high-strength steel, providing a stable rear for the moving truss 2. The drive device 3 is fixed to the ground or mounting base, while remaining relatively fixed to the static truss 1. The drive device 3 is connected to the foremost telescopic platform assembly, and the telescopic movement of the moving truss 2 is achieved by pulling or pushing.

[0049] In this embodiment, the independent arrangement of multiple telescopic platform components, through nested telescopic platform components and stacking space formed by lateral notches, allows multiple telescopic platform components to not only be compactly nested and stored, but also to adjust the number and height of telescopic platform components according to different environments. This solves the problem that traditional fixed telescopic platforms are difficult to adapt to different site requirements, and significantly improves the flexibility and scene adaptability of the equipment.

[0050] In this embodiment, "front and rear" refers to the telescopic direction along the telescopic platform. The front end is the telescopic end of the moving truss 2, and the rear end is the fixed end where the static truss 1 is located. It should be noted that the static truss 1 and the drive device 3 in this application can adopt the corresponding structure of existing telescopic platform equipment, which will not be elaborated here.

[0051] For further details, please refer to... Figure 3 and Figure 4The telescopic platform equipment has an extended state and a retracted state. In the retracted state, multiple sets of telescopic platform components are stacked at the static truss 1. In the extended state, multiple sets of telescopic platform components are distributed in a stepped manner. In other embodiments, multiple sets of telescopic platform components at the same height can also be provided to increase the overall usable range of the telescopic platform equipment. The supporting crossbeams 22 of the telescopic platform components at the same height are fixed together by bolts to achieve synchronous movement.

[0052] Please refer to Figure 1 In this embodiment of the application, the moving truss 2 is composed of multiple sets of independently detachable telescopic platform components connected in series. The frontmost telescopic platform component is driven by the drive device 3, and the push or pull of the drive device 3 sequentially drives the rear telescopic platform components to move.

[0053] For details, please refer to Figure 3 , Figure 4 and Figure 5 The supporting crossbeam 22 includes a baffle frame 221, a baffle strip 222, and multiple support rods 223. The support rods 223 are arranged along the extension direction, and the multiple support rods 223 are distributed in parallel and fixed to the stepped platform 21. The crossbeam and the baffle frame 221 are both arranged perpendicular to the support rods 223. The baffle strip 222 is fixed to the lower end of the support rod 223 and is arranged near the rear end of the support rod 223. The baffle frame 221 is fixed to the upper end of the support rod 223 and is arranged near the rear end of the support rod 223. The baffle frame 221, the baffle strip 222, and the multiple support rods 223 together constitute the transverse frame of the supporting crossbeam 22. The baffle frame 221 and the support rods 223 are both made of lightweight aluminum alloy profiles with rectangular cross sections. The baffle strip 222 is made of inverted "U" shaped steel. The connection method is welding or bolt locking.

[0054] Please refer to Figure 2 , Figure 3 and Figure 4 The supporting frame 23 includes at least two uprights 231. The uprights 231 are made of lightweight aluminum alloy profiles with rectangular cross sections. Their upper ends are fixed to the baffle frame 221 and their lower ends are fixed to the supporting base frame 24. The connection method is welding or bolt locking.

[0055] Please refer to Figure 3 , Figure 4 and Figure 5The supporting base frame 24 cooperates with the supporting vertical frame 23, including at least two base rods 241. The base rods 241 are made of inverted "U"-shaped steel. The lower end of the supporting vertical frame 23 is fixed to the upper end of the base rods 241. The lower end of the base rods 241 is a slot in the steel. The connection method is welding or bolt locking. In this embodiment, multiple sets of supporting base frames 24 are staggered to adapt to the stacking space of the lateral gaps. Specifically, the supporting base frames 24 of the multiple telescopic platform assemblies are staggered from the outside to the inside, that is, the supporting base frame 24 corresponding to the highest telescopic platform assembly is set on the outermost side of all telescopic platform assemblies.

[0056] Please refer to Figure 3 , Figure 4 and Figure 5 A reinforcing frame 27 is provided between the supporting horizontal frame 22 and the supporting vertical frame 23. Specifically, the reinforcing frame 27 includes a diagonal support rod 271 and a horizontal rod 272. The horizontal rod 272 is fixed to the lower end of the supporting rod 223 and is set near the rear end of the supporting rod 223. The horizontal rod 272 is parallel to the baffle strip. The upper end of the diagonal support rod 271 is fixed to the horizontal rod 272, and the lower end is fixed to the vertical rod 231. The diagonal support rod 271 and the vertical rod 231 are set at a non-zero angle. Both the diagonal support rod 271 and the horizontal rod 272 are made of lightweight aluminum alloy profiles with rectangular cross sections. Their connection method is welding or bolt locking.

[0057] Please refer to Figure 3 , Figure 4 and Figure 5 The movable wheel assembly 25 includes multiple movable wheels, which are distributed along the telescopic direction and rotatably mounted in the slot at the lower end of the base rod 241 to facilitate the retraction and deployment of the telescopic platform assembly.

[0058] Please refer to Figure 3 , Figure 4 and Figure 5 Several support wheel assemblies 28 are distributed on the upper end of the support crossbeam 22. The axis of the support wheel assembly 28 is parallel to the axis of the movable wheel assembly 25, and the upper end of the support wheel assembly 28 is in rolling contact with the adjacent telescopic platform assembly. Specifically, each support rod 223 is provided with a corresponding movable wheel. The wheel frame of the movable wheel is fixed on the support rod 223, and the upper end of the movable wheel is a wheel used to support and roll along the support rod 223 at the adjacent height.

[0059] In the embodiments of this application, please refer to Figure 3 , Figure 4 and Figure 5The support wheels are specifically distributed on one side of the rear end of the baffle frame 221 and are set on the upper end face of the support rod 223 near the rear end. The stop bar 222 is set on the lower end face of the support rod 223 near the front end. When the telescopic platform assemblies of adjacent heights move relative to each other, the support wheels roll along the length direction of the upper support rod 223. The stop bar 222 is on the support rod 223 and is used to limit the movement range of the support wheels. When unfolded, it provides a limit for the telescopic platform assembly to prevent it from detaching.

[0060] Please refer to Figure 3 , Figure 4 and Figure 5 The stepped platform 21 includes mutually perpendicular support plates 211 and upright plates 212. The support plates 211 are located at the upper end of the support crossbeam 22, and the upright plates 212 are located at the front end of the support plates 211 along the telescopic direction, forming a stepped right angle with the support plates 211. A baffle frame 221 is located on the upper end face of the support rod 223 near the rear end. The upright plates 212 are located at the front end of the support rod 223 and extend downward, so that the baffle frame 221 and the upright plates 212 of the adjacent height telescopic platform assembly have an overlap section in height, thereby limiting the expansion range of the telescopic platform assembly and providing a limit for the telescopic platform assembly during expansion to prevent it from detaching. During disassembly and assembly, the telescopic platform assembly can be removed from top to bottom by raising the upper upright plate 212 above the lower baffle frame 221 to detach it.

[0061] Please refer to Figure 3 , Figure 4 and Figure 5 The telescopic platform assembly also includes a locking element 29, which is used to fix adjacent telescopic platform assemblies. Specifically, the locking element 29 includes a locking plate 291 and a latch 292. The locking plate 291 is fixed near the front end of the support base 24, and the latch 292 is rotatably mounted on the upright 231 of the support frame 23 and located near the rear end of the support base 24. The latch 292 has a slot 293 for locking the locking plate 291. The locking plate 291 extends toward the interior of the storage space 26 to block the support frame 23 of the adjacent telescopic platform assembly. When unfolded, the lower telescopic platform assembly reaches the corresponding position, the locking plate 291 blocks the continued movement of the support frame 23 of the lower telescopic platform assembly, and then the latch 292 is rotated to engage the slot 293 with the latch 292, thereby locking the adjacent telescopic platform assemblies.

[0062] It should also be noted that the lowest telescopic platform assembly can have a moving wheel assembly 25 directly installed at the lower end of the supporting crossbeam 22, serving as the frontmost stepped platform 21. Due to the modular design between the various components, and the modular design between the static truss 1 and the moving truss 2, the specific selection of the static truss, the height and quantity of the telescopic platform assembly can all be adjusted according to the site conditions.

[0063] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
