Description

Technical Field

[0001] This invention relates to the field of tower building machines, specifically an intelligent tower building machine and its safety protection device. Background Technology

[0002] A tower-building machine is a system used to construct tall tower structures such as television towers, communication towers, power transmission towers, and wind power towers. It is not a single machine, but a highly integrated and intelligent large-scale engineering machinery equipment combination designed to improve the efficiency, precision, and safety of tower structure construction.

[0003] In the process of building tall towers, existing tower-building machines often focus on the construction of the tower body. As the tower-building machine continues to ascend, the working height increases. Construction workers cannot freely work on the tower surface below the level of the tower-building machine. Generally, a crane is set up on the surface of the tower-building machine, and workers are lowered into a basket connected to the crane to work. This working method is too inconvenient and lacks safety protection devices, so the safety of workers cannot be guaranteed. Moreover, working in the basket below restricts the flexibility of workers, making it extremely inconvenient. Summary of the Invention

[0004] This invention provides an intelligent tower-building machine and its safety protection device, which overcomes the shortcomings described in the background art.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] An intelligent tower-building machine and its safety protection device include a tower-shaped structure and a building machine body for constructing the tower-shaped structure. The tower-shaped structure includes a tower body and prefabricated embedded steel plates set inside the tower body. The building machine body includes a support, a working platform, a climbing device, and a lifting mechanism. The support is arranged in a ring around the tower body. The working platform is set outside the tower body, and each support passes through the working platform. Multiple climbing devices are provided on the surface of the working platform near each support. The working platform is driven to rise and fall on the support by the climbing devices. Multiple inwardly extending extension platforms are provided on the side of the working platform facing the tower body. A winding motor is fixed to a second working platform by a mounting plate.

[0007] The prefabricated embedded steel plate includes a steel plate body installed inside the tower body and a working platform. The steel plate body has an I-shaped cross-section, and the two side surfaces of the steel plate body are flush with the surface of the tower body. The working platform passes through the steel plate body.

[0008] The working platform includes a main insert plate, a secondary insert plate, and a C-shaped fixing plate. The main insert plate is inserted into the steel plate body, and the secondary insert plate is connected to the main insert plate through the C-shaped fixing plate. A rectangular notch is formed between the secondary insert plate and the main insert plate to allow the lifting mechanism to pass through.

[0009] In a preferred embodiment, the lifting mechanism includes a lifting cabin and multiple winding motors. Each winding motor has a winding wheel mounted on its output shaft. Steel cables are connected to both the upper and lower ends of the lifting cabin. The steel cable at the upper end of the lifting cabin is connected to the winding wheel on the output shaft of the winding motor, while the steel cable at the lower end of the lifting cabin is connected to a tensioning wheel located at the bottom of the tower. The winding motor controls the winding wheel to wind and unwind the steel cable, thereby raising and lowering the lifting cabin, and the tensioning wheel maintains the tension of the steel cable.

[0010] In a preferred embodiment, the adjacent ends of the main insert plate and the auxiliary insert plate are provided with C-shaped openings, and the two C-shaped openings form a rectangular notch for the elevator compartment to pass through.

[0011] The auxiliary insert plate has an extension on the side near the main insert plate. The auxiliary insert plate is inserted into the main insert plate through the extension. The surfaces of the main insert plate and the auxiliary insert plate near the extension are provided with positioning holes. The upper and lower adjacent positioning holes are on the same axis. Multiple positioning holes on the same axis form a limiting hole. Each limiting hole is provided with a pin.

[0012] The C-shaped fixing plate has a C-shaped cross-section and is fastened to the connection end of the main insert plate and the auxiliary insert plate. The surface of the C-shaped fixing plate is provided with multiple insertion ports II, which correspond to the adjacent limiting holes.

[0013] In a preferred embodiment, the tower body is further provided with reinforcing bars that penetrate through the steel plate body. The main insert plate has multiple notches on the side near the reinforcing bars, and the notches are staggered from the reinforcing bars. The secondary insert plate is also staggered from the reinforcing bars.

[0014] A safety protection device for an intelligent tower-building machine, based on the aforementioned intelligent tower-building machine, is characterized in that it includes a protective device set on a prefabricated embedded steel plate. The protective device includes a baffle, a barrier, and a railing. The baffle is symmetrically arranged on both sides of the rectangular notch, while the barrier is symmetrically arranged on the surface of the auxiliary insert plate, and the two adjacent barriers on the left and right sides and the adjacent baffle are arranged in the same axial direction.

[0015] Both baffles have openings on their adjacent surfaces. One end of the railing is connected to the steel plate body, while the other end passes through the opening and the baffle adjacent to the opening in sequence.

[0016] The barrier has a U-shaped cross-section and is inserted into the sub-insertion plate through an insertion port on the surface of the sub-insertion plate.

[0017] In a preferred embodiment, a limiting plate is also inserted into the side of the barrier, the limiting plate extending into the barrier and abutting against the lower end of the opening plate.

[0018] In a preferred technical solution, the upper parts of both baffles are inclined outwards, and the lower part of the baffles is provided with multiple openings corresponding to the pins. When the C-shaped fixing plate is fixed by the pins, the pins first pass through the openings and then insert into the limiting holes.

[0019] Compared with existing technologies, this technical solution has the following advantages:

[0020] During the tower body casting stage, the main insert plate is embedded into the precast embedded steel plate in an arc-shaped steel plate body, and the auxiliary insert plate is rigidly connected to the main insert plate through a C-shaped fixing plate to form a stable outward structure. As the tower building machine body continues to rise along the support through the climbing device, it can directly move from the elevator cabin to the required working platform to perform operations such as spraying, welding, inspection or installation of auxiliary components on the outer surface of the tower body, without having to continuously rely on the suspended platform for operation.

[0035] like Figures 1 to 8 As shown, the present invention proposes an intelligent tower building machine and its safety protection device, including a tower-shaped structure 1 and a building machine body 2 for building the tower-shaped structure 1. The tower-shaped structure 1 includes a tower body 11 and a prefabricated embedded steel plate 12 disposed in the tower body 11. The building machine body 2 includes a support 21, a second working platform 22, a climbing device 23 and a lifting mechanism 26. The support 21 is arranged in a ring around the tower body 11. The second working platform 22 is disposed outside the tower body 11, and each support 21 passes through the second working platform 22. Multiple climbing devices 23 are respectively provided on the surface of the second working platform 22 near each support 21. The second working platform 22 is driven to rise and fall on the support 21 by the climbing device 23. Multiple inwardly extending extension platforms 24 are provided on the side of the second working platform 22 facing the tower body 11. The winding motor 262 is fixed to the second working platform 22 by a mounting plate 25.

[0036] As mentioned above, the steel plate body 121 is pre-embedded and fixed inside the tower body 11 during its construction. Specifically, during the concrete pouring or segmental assembly stage of the tower body 11, the bow-shaped steel plate body 121 is precisely positioned and cast or installed as a structural embedded part at a designated height position on the tower body 11. Its two side surfaces are flush with the outer surface of the tower body 11, ensuring the continuous appearance of the tower body and uniform stress. This pre-embedding method eliminates the need for additional drilling or welding of support structures during subsequent construction. The steel plate body 121, which is already integrated into the tower body, can be directly used as the installation base of the first working platform 122, providing a stable and reliable insertion and load-bearing interface for the main insertion plate 1221, thereby realizing the integrated and collaborative construction of the first working platform 122 and the tower body 11.

[0037] The prefabricated embedded steel plate 12 includes a steel plate body 121 installed inside the tower body 11 and a first working platform 122. The steel plate body 121 has an I-shaped cross-section, and the two side surfaces of the steel plate body 121 are flush with the surface of the tower body 11. The first working platform 122 passes through the steel plate body 121. The first working platform 122 includes a main insert plate 1221, a secondary insert plate 1222, and a C-shaped fixing plate 1223. The main insert plate 1221 is inserted into the steel plate body 121, and the secondary insert plate 1222 is connected to the main insert plate 1221 through the C-shaped fixing plate 1223. A rectangular notch is formed between the secondary insert plate 1222 and the main insert plate 1221 for the lifting mechanism 26 to pass through.

[0038] In this invention, the first working platform 122, as part of the tower body 11 structure, is embedded in the bow-shaped steel plate body 121 of the prefabricated embedded steel plate 12 during the tower body 11 casting stage via the main insert plate 1221. The auxiliary insert plate 1222 is rigidly connected to the main insert plate 1221 via the C-shaped fixing plate 1223, forming a stable extended structure. As the tower building machine body 2 continues to operate and rise along the support 21 via the climbing device 23, its built-in extension platform 24 can extend horizontally and precisely connect with the first working platform 122 pre-embedded in the tower body. At this time, construction personnel can directly ascend to the corresponding surface of the first working platform 122 via the lifting cabin 261 set on the second working platform 22 of the tower building machine to perform operations such as spraying, welding, inspection, or installing auxiliary components on the outer surface of the tower body, without relying on the suspended platform for operation.

[0039] Furthermore, the lifting mechanism 26 includes a lifting cabin 261 and multiple winding motors 262. Each winding motor 262 has a winding wheel mounted on its output shaft. The upper and lower ends of the lifting cabin 261 are connected to steel cables 2611. The steel cable 2611 at the upper end of the lifting cabin 261 is connected to the winding wheel on the output shaft of the winding motor 262, while the steel cable 2611 at the lower end of the lifting cabin 261 is connected to the tensioning wheel 263 located at the bottom of the tower body 11. The winding motors 262 control the winding wheel to wind and unwind the steel cable 2611, raising and lowering the lifting cabin 261, and the tensioning wheel 263 keeps the steel cable 2611 taut.

[0040] Furthermore, the adjacent ends of the main insert plate 1221 and the auxiliary insert plate 1222 are provided with C-shaped openings, and the two C-shaped openings form a rectangular notch for the elevator cabin 261 to pass through.

[0041] The auxiliary insert plate 1222 is provided with an extension 2222 on the side near the main insert plate 1221. The auxiliary insert plate 1222 is inserted into the main insert plate 1221 through the extension 2222. The surfaces of the main insert plate 1221 and the auxiliary insert plate 1222 near the extension 2222 are provided with positioning holes. The upper and lower adjacent positioning holes are on the same axis. Multiple positioning holes on the same axis form a limiting hole. Each limiting hole is provided with a pin 2232.

[0042] The C-shaped fixing plate 1223 has a C-shaped cross-section and is fastened to the connection end of the main insert plate 1221 and the auxiliary insert plate 1222. The surface of the C-shaped fixing plate 1223 is provided with a plurality of insertion holes 2231, which correspond to the adjacent limiting holes.

[0043] During the construction of tower body 11, the bow-shaped steel plate body 121 is pre-embedded at a designated height, with a pre-drilled groove inside for the main insert plate 1221 to be inserted. After the tower builder body 2 climbs to approximately this height, the construction workers precisely push the main insert plate 1221 horizontally into the inner cavity of the steel plate body 121, ensuring it is fully in place and fits snugly against the tower structure. The main insert plate 1221, as the load-bearing main body, has its position guaranteed by the pre-embedding precision, eliminating the need for on-site welding or drilling.

[0044] Subsequently, the auxiliary insert plate 1222 is aligned with the outer side of the main insert plate 1221 for mating. The auxiliary insert plate 1222 has an extension 2222 near the connecting end, which can slide into the corresponding slot of the main insert plate 1221, forming a preliminary mechanical engagement. During insertion, the positioning holes on the main insert plate 1221 and the auxiliary insert plate 1222 automatically align, forming coaxial limiting holes vertically and vertically. At this point, the installer inserts pins 2232 sequentially into each limiting hole, achieving precise positioning and shear-resistant locking of the main and auxiliary insert plates in the vertical and horizontal directions, effectively preventing relative slippage or loosening.

[0045] Finally, the C-shaped fixing plate 1223 is fastened to the connection end between the main insert plate 1221 and the auxiliary insert plate 1222 from the outside. Since the C-shaped fixing plate 1223 has an open C-shaped cross-section, it can be directly snapped into place without disassembling other components. Its covering structure further constrains the lateral displacement of the main and auxiliary insert plates and enhances the overall connection rigidity. At this point, the first working platform 122 completes rapid assembly. The resulting rectangular notch precisely avoids the passageway of the lifting cabin 261, without affecting the normal operation of the lifting mechanism 26. The entire installation process requires no high-altitude welding, bolt tightening, or large hoisting equipment; it can be completed in just three steps: insertion, pinning, and snapping, significantly improving installation efficiency and operational safety.

[0046] Furthermore, after the tower body 11 is constructed to the pre-embedded height, operators ride in the lifting cabin 261 driven by the lifting mechanism 26, precisely stopping at the elevation corresponding to the steel plate body 121. Since the main insert plate 1221 needs to be horizontally inserted into the inner cavity of the steel plate body 121, and this location is usually on the outside of the tower body with no readily available working surface, it is difficult to safely approach using traditional methods. At this time, the lifting cabin 261, as a temporary high-altitude work platform, can be stably suspended in front of the installation point, providing a safe and stable operating platform for construction personnel.

[0047] Furthermore, the tower body 11 is also equipped with reinforcing bars 111, which penetrate through the steel plate body 121. The main insert plate 1221 has multiple notches 2211 on the side near the reinforcing bars 111, with the notches 2211 offset from the reinforcing bars 111. The secondary insert plate 1222 is also offset from the reinforcing bars 111. The reinforcing bars 111 serve as the main load-bearing framework of the tower body 11, providing tensile strength and structural integrity. Their penetration through the steel plate body 121 enhances the collaborative load-bearing capacity between the embedded area and the tower body concrete. The notches and offset design on the main insert plate 1221 and the secondary insert plate 1222 effectively avoid the reinforcing bars 111, ensuring smooth installation while preventing damage to the internal load-bearing system of the tower body.

[0048] A safety protection device for an intelligent tower-building machine, based on the aforementioned intelligent tower-building machine, includes a protective device 13 installed on a prefabricated embedded steel plate 12. The protective device 13 includes a baffle 131, a barrier 132, and a railing 133. The baffle 131 is symmetrically arranged on both sides of a rectangular notch, while the barrier 132 is symmetrically arranged on the surface of the auxiliary insert plate 1222. The two adjacent barriers 132 on the left and right are arranged in the same axial direction as the adjacent baffle 131.

[0049] Both baffles 131 have openings 1311 on their adjacent surfaces. One end of the railing 133 is connected to the steel plate body 121, while the other end passes through the opening 1311 and the baffle 132 adjacent to the opening 1311. The baffle 132 has a U-shaped cross-section and is inserted into the sub-insertion plate 1222 through the insertion port 2221 provided on the surface of the sub-insertion plate 1222.

[0050] This invention significantly improves the safety of high-altitude operations by integrating a protective device 13 into a prefabricated embedded steel plate 12. The baffle 131 is symmetrically positioned on both sides of the rectangular opening, effectively shielding the gap between the passage area of ​​the lifting cabin 261 and the first working platform 122, preventing accidental falls of personnel or tools. The guardrail 132, with a U-shaped structure, is inserted into the auxiliary insert plate 1222, forming a continuous and stable lateral enclosure, preventing workers from slipping or becoming unstable while working on the outer surface of the tower. The railing 133 penetrates the opening plate 1311 of the baffle 131 and is rigidly connected to the steel plate body 121, forming an integral protective frame that not only enhances structural stability but also provides reliable handrail support. The three elements work together to achieve a fully enclosed, high-rigidity safety protection system without the need for additional temporary guardrails, effectively eliminating the risk of falls due to swaying and lack of protection in traditional suspended platform operations, and ensuring the safety of workers operating in the lower sections of the tower.

[0051] Furthermore, the protective device 13 adopts a modular plug-in and through-type fixing design, which greatly simplifies the high-altitude installation process. The guardrail 132 is directly inserted through the pre-set plug-in 2221 of the auxiliary plug plate 1222, without the need for bolt tightening or welding, realizing "plug and play".

[0052] Furthermore, a limiting plate 1321 is inserted into the side of the barrier 132, the limiting plate 1321 extends into the barrier 132 and abuts against the lower end of the opening plate 1311.

[0053] Furthermore, the upper parts of both baffles 131 are inclined outward, and the lower part of the baffles 131 is provided with multiple openings corresponding to the pins 2232. When the C-shaped fixing plate 1223 is fixed by the pins 2232, the pins 2232 first pass through the openings and then insert into the limiting holes.

[0054] The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.
