Technical Field

[0001] This invention relates to the field of thin-walled hollow pier technology, and in particular to a thin-walled hollow high pier flip-type steel formwork platform system. Background Technology

[0002] Steel frame platforms, also known as work platforms or steel structure platforms, come in various structural forms and can be designed and manufactured to meet different site conditions, satisfying site requirements, functional requirements, and logistics requirements. They are widely used in modern storage. However, most steel frame platforms currently used for thin-walled hollow piers are fixed structures that cannot be folded for storage, making disassembly and assembly very troublesome and construction time-consuming. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an improved thin-walled hollow high pier flip-type steel formwork platform system in order to solve the problem that most of the steel frame platforms currently used for thin-walled hollow piers are fixed structures that cannot be folded and stored, resulting in very troublesome disassembly and assembly and long construction period.

[0004] The technical solution adopted by this invention to solve its technical problem is: a thin-walled hollow high-pier flip-type steel formwork platform system, including a top platform body, a middle platform body, and a bottom platform body. Strip-shaped side storage slots are provided on the four sides of the top platform body, middle platform body, and bottom platform body. A self-rotating climbing staircase is movably installed inside each strip-shaped side storage slot. Bottom-side translation guide rails are fixedly installed on the lower surfaces of the top platform body and middle platform body on both sides of the strip-shaped side storage slots. Electrically controlled limit control frames for adjusting the angle of the self-rotating climbing staircase are movably installed inside the bottom-side translation guide rails. Electrically controlled threaded limit tooth frames are installed on the outer walls on both sides of the self-rotating climbing staircase.

[0005] The top platform body, middle platform body, and bottom platform body are all U-shaped structure platforms, and the strip-shaped side storage slots on the top platform body, middle platform body, and bottom platform body are staggered in their longitudinal positions.

[0006] The electrically controlled limit control frame includes an electrically controlled lead screw movably mounted inside the bottom translation guide rail, an internally threaded adjusting slider slidably mounted inside the bottom translation guide rail, and a flip-limit frame movably mounted on one side of the internally threaded adjusting slider.

[0007] The self-flipping climbing staircase includes a flipping staircase frame with lateral mounting shafts at the upper and lower ends on both sides, a flipping step movably mounted inside the flipping staircase frame, an inner control device installed inside both sides of the flipping staircase frame, and a side mounting base fixed at both ends of the outer side of the flipping staircase frame.

[0008] The electrically controlled threaded limit gear frame includes a side-mounted internal gear frame with external threaded mounting rods on both sides of the upper end, an internal threaded adjusting cylinder movably mounted inside the side-mounted mounting base, and a top-mounted adjusting motor fixed to the upper end of the side-mounted mounting base for controlling the rotation of the internal threaded adjusting cylinder.

[0009] The lower surfaces of both the top platform body and the middle platform body have an integrated structural assembly frame that mates with the flip-up staircase frame. The upper surfaces of both the middle platform body and the bottom platform body have an integrated structural assembly guide rail that mates with the flip-up staircase frame. A bottom-positioned translation slider is slidably installed inside the assembly guide rail. The flip-up staircase frame is movably connected to the corresponding assembly frame via a lateral assembly shaft at the upper end. The flip-up staircase frame is slidably connected to the corresponding assembly guide rail by inserting a lateral assembly shaft at the lower end into the bottom-positioned translation slider.

[0010] The top platform body, the lower surface of the middle platform body, and the upper surface of the bottom platform body are all equipped with horizontal telescopic screw limiting mechanisms.

[0011] The inner control device includes a horizontal linkage rod movably installed inside both sides of the flip-up staircase frame, an integrated worm gear axially sleeved on the outside of the horizontal linkage rod, a turbine axially fixed on the mounting shafts on both sides of the flip-up pedal, and an external rotation adjustment mechanism installed on the side wall of the flip-up staircase frame.

[0012] The lower end of the flip-up stairwell frame has a bottom linkage control bracket that protrudes downwards.

[0013] The beneficial effects of this invention are:

[0014] (1) The thin-walled hollow high-pier flip-type steel formwork platform system of the present invention adopts an electronic control structure design, which can quickly lift and unfold, and the operation is very convenient and fast;

[0015] (2) The stackable structure design can greatly reduce the external structure when not in use, making it convenient for transportation and storage;

[0016] (3) By providing strip-shaped side storage slots with self-rotating climbing staircases installed inside on all four sides, the platform body at the bottom can be raised and lowered and limited while climbing, greatly enhancing the functional integration.

[0017] (4) By installing an electrically controlled threaded limit tooth frame for limiting the electrically controlled limit control frame on the outer walls of both sides of the self-rotating climbing staircase, the limiting ability of the self-rotating climbing staircase can be improved, the safety and stability can be greatly improved, and the loading and unloading can be convenient.

[0018] (5) The self-flipping climbing staircase is equipped with flipping steps, which can improve the space utilization in the storage state while making it easier to climb and reduce the gap between the platform bodies in different positions. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] Figure 1 , Figure 2 and Figure 3 The thin-walled hollow high-pier flip-type steel formwork platform system shown includes a top platform body 1, a middle platform body 2, and a bottom platform body 3. Strip-shaped side storage grooves 4 are provided on the four sides of the top platform body 1, middle platform body 2, and bottom platform body 3. A self-rotating climbing staircase is movably installed inside the strip-shaped side storage grooves 4. Bottom side sliding guide rails 5 are fixedly installed on the lower surfaces of the top platform body 1 and middle platform body 2 on both sides of the strip-shaped side storage grooves 4. Electrically controlled limit control frames for adjusting the angle of the self-rotating climbing staircase are movably installed inside the bottom side sliding guide rails 5. Electrically controlled threaded limit tooth frames are installed on the outer walls on both sides of the self-rotating climbing staircase.

[0026] To facilitate installation and easy access, the top platform body 1, the middle platform body 2, and the bottom platform body 3 are all U-shaped platforms, with the longitudinal strip-shaped side storage slots 4 on the top platform body 1, the middle platform body 2, and the bottom platform body 3 being staggered.

[0027] To facilitate translation adjustment, the electrically controlled limit control frame includes an electrically controlled lead screw 6 movably mounted inside the bottom translation guide rail 5, an internal thread adjustment slider 7 slidably mounted inside the bottom translation guide rail 5, and a flip limit frame 8 movably mounted on one side of the internal thread adjustment slider 7.

[0028] The electrically controlled lead screw 6 is existing technology, which drives the internal thread adjustment slider 7 to adjust inside the bottom side translation guide rail 5 by rotation.

[0029] To facilitate flipping and lifting adjustments, the self-flipping climbing staircase includes a flipping staircase frame 9 with lateral mounting shafts at the upper and lower ends on both sides, a flipping step 10 movably mounted inside the flipping staircase frame 9, an inner control device installed inside both sides of the flipping staircase frame 9, and a side mounting base 11 fixed at both ends of the outer side of the flipping staircase frame 9.

[0030] To facilitate lifting and limiting, the electrically controlled threaded limit gear frame includes a side-mounted internal gear frame 13 with external threaded mounting rods 12 on both sides of the upper end, an internal threaded adjusting cylinder 14 movably mounted inside the side mounting base 11, and a top-mounted adjusting motor 15 fixed to the upper end of the side mounting base 11 for controlling the rotation of the internal threaded adjusting cylinder 14.

[0031] The top-mounted adjusting motor 15 is existing technology. It controls the lifting and lowering of the side-mounted inner toothed frame 13 by rotating the internal threaded adjusting cylinder 14. When the side-mounted inner toothed frame 13 is raised, the position of the bottom of the tilting limit frame 8 and the lower surface of the tilting staircase frame 9 remains unchanged. At this time, the tilting limit frame 8 can drive the tilting staircase 9 to tilt. When the side-mounted inner toothed frame 13 is lowered, the tilting limit frame 8 separates from the inner bottom tooth surface of the side-mounted inner toothed frame 13. At this time, the contact surface position between the tilting limit frame 8 and the tilting staircase 9 can be adjusted.

[0032] To facilitate the upper movable assembly and the bottom sliding assembly, the lower surfaces of the top platform body 1 and the middle platform body 2 each have an integrated structural assembly frame that mates with the flip-up staircase frame 9. The upper surfaces of the middle platform body 2 and the bottom platform body 3 each have an integrated structural assembly guide rail 16 that mates with the flip-up staircase frame 9. A bottom sliding slider 17 is slidably installed inside the assembly guide rail 16. The flip-up staircase frame 9 is movably connected to the corresponding assembly frame via the upper lateral assembly shaft. The flip-up staircase frame 9 is slidably connected to the corresponding assembly guide rail 16 via the lower lateral assembly shaft inserted into the bottom sliding slider 17.

[0033] To improve structural stability, a bottom lead screw can be installed on the outside of the mounting guide rail 16. The bottom lead screw is driven to rotate by a motor of existing technology on the outside, thereby controlling the translation adjustment of the bottom sliding slider 17, thereby improving the stability of the bottom of the flip-up stairwell frame 9.

[0034] In order to cooperate with the lateral extrusion limit and maintain the stability of the inner assembly end, the lower surface of the top platform body 1, the middle platform body 2 and the upper surface of the bottom platform body 3 are all equipped with a horizontal telescopic screw limit mechanism 18.

[0035] The transverse telescopic screw limiting mechanism 18 includes an integral internal threaded fixing seat welded and fixed to the lower surface of the top platform body 1, the middle platform body 2 and the upper surface of the bottom platform body 3, and an external threaded telescopic limiting rod threaded into the internal threaded fixing seat. The external threaded telescopic limiting rod is matched with lateral limiting holes opened on the side walls of the top platform body 1, the middle platform body 2 and the bottom platform body 3, thereby improving the stability of lateral extrusion and the lateral limiting performance.

[0036] To facilitate angle adjustment, the inner control device includes a horizontal linkage rod 19 movably installed inside both sides of the flip-up staircase frame 9, an integral worm gear 20 axially sleeved on the outside of the horizontal linkage rod 19, a turbine 21 axially fixed on the mounting shafts on both sides of the flip-up pedal 10, and an external rotation adjustment mechanism 22 installed on the side wall of the flip-up staircase frame 9.

[0037] The external rotation adjustment mechanism 22 consists of a lateral control rod that meshes with the teeth at one end of the transverse linkage rod 19 and a rotary handle axially mounted on the outer end of the lateral control rod. By controlling the rotation of the rotary handle, the transverse linkage rod 19 is driven to rotate. The transverse linkage rod 19 drives the worm gear 21, which meshes with the worm gear 20, to rotate, thereby controlling the flip-type pedal 10 to flip.

[0038] To enhance the safety of the side-mounted inner toothed frame 13, the lower end of the flip-up stairwell frame 9 has a bottom linkage control bracket 23 that protrudes downwards.

[0039] The bottom linkage control bracket 23 is set around the side-mounted inner toothed frame 13, which can limit the maximum adjustment range of the side-mounted inner toothed frame 13.

[0040] This invention discloses a thin-walled hollow high-pier flip-type steel formwork platform system. It features an electrically controlled structure design, enabling rapid lifting and unfolding, making operation extremely convenient and quick. The stackable structure design allows for significant reduction in external size during off-peak hours, facilitating transportation and storage. Strip-shaped side storage slots 4, each located on one of the four side walls, provide internal installation of a self-flipping climbing staircase, ensuring lifting and limiting of the platform body at the bottom during climbing, greatly enhancing functional integration. Electrically controlled threaded limit frames, installed on the outer walls of both sides of the self-flipping climbing staircase for limiting the electrically controlled limit frame, improve the limiting capability of the self-flipping climbing staircase, significantly enhancing safety and stability while facilitating loading and unloading. The self-flipping climbing staircase is equipped with flip-type footboards 10, which improves space utilization in the stored state while facilitating climbing and reducing gaps between platform bodies at different locations.

[0041] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
