Description

Technical Field

[0001] This invention belongs to the field of engineering construction technology, and specifically relates to a fully automatic construction lifting platform system for climbing and supporting. Background Technology

[0002] In the construction of super high-rise buildings and silo structures, traditional construction hoisting platforms mostly use hydraulic jacking or wire rope traction technology, which has the following limitations: Hydraulic cylinder-driven platform jacking relies on external hydraulic pump stations and complex piping systems. Disadvantages include: hydraulic system prone to oil leaks, high maintenance costs, and poor stability due to temperature variations; manual intervention is required for positioning during jacking, resulting in low efficiency (approximately 1-2 hours per jacking cycle); limited load-bearing capacity (generally ≤50 tons), making it unsuitable for large-span silo structures. Screw-driven jacking systems (such as a certain model SC200 / 200 construction elevator): drive a screw to rotate, raising and lowering the platform along guide rails. Disadvantages include: severe wear due to sliding friction between the screw and nut, resulting in a transmission efficiency of only 60%-70%; lack of dynamic anti-fall mechanism, relying solely on mechanical brakes with slow response (≥0.5 seconds); non-modular platform structure, difficult disassembly, and inability to adapt to rapid site relocation. Traditional bracket support technology involves manually inserting brackets into pre-reserved openings in the building structure for temporary support. The extension and retraction of the brackets requires manual intervention, posing a risk of working at height; the support switching is time-consuming (approximately 30 minutes per operation), affecting the continuity of construction; the poor positioning accuracy of the brackets (error ≥ 5mm) can easily lead to stress concentration in the structure.

[0003] The aforementioned technologies generally suffer from problems such as low automation, insufficient safety, and limited efficiency, making it difficult to meet the core requirements of modern super high-rise buildings for efficient, precise, and fully automated construction platforms. Summary of the Invention

[0004] This invention aims to provide a system and method for climbing and supporting a fully automatic construction lifting platform. By using the helical pair transmission between the screw and the ball nut, friction loss can be reduced, and the platform can be raised and lowered smoothly. By adopting the bidirectional anti-fall automatic switching device, the relative movement direction between the top construction platform and the guide rail can be limited, ensuring the safety of the fully automatic construction lifting platform system for climbing and supporting.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A fully automatic construction lifting platform system for climbing and supporting includes a base support platform, a guide rail, four climbing drive devices, several automatic telescopic bracket devices, a top construction work platform, and four bidirectional automatic fall protection switching devices. The guide rail is vertically fixed in the middle of the base support platform. The guide rail has a rectangular cross-section, and its four side plates are provided with several equally spaced slots along their axial direction. The climbing drive device includes a climbing drive mechanism, a screw, and ball nuts. The climbing drive mechanism is located at the four corners of the base support platform. A guide rail channel is opened in the middle of the top construction work platform for the guide rail to pass through. Screw channels are opened at the four corners of the top construction work platform for corresponding screws to pass through. The lower end of the screw is driven by the corresponding climbing drive mechanism, and the upper end of the screw connects with the corresponding ball nuts. The four ball nuts are fixedly installed at the four corners of the top construction platform. At least two automatic extension and retraction devices for the brackets are provided on both sides of the base support platform and on both sides of the bottom of the top construction platform. The automatic extension and retraction devices for the brackets can extend to support the brackets in the reserved holes in the wall or retract to disengage the brackets from the reserved holes in the wall. Through the cooperation of the climbing drive device and the automatic extension and retraction devices for the brackets, the top construction platform and the base support platform can be alternately climbed. The two-way automatic fall protection switching devices are respectively installed on the top construction platform.

[0017] A method for using a fully automatic construction lifting platform system for climbing and supporting, employing the fully automatic construction lifting platform system for climbing and supporting as described above, the method comprising the following steps: Step 1: Switch the two-way fall protection automatic switching device to the upward mode. The top construction work platform is ready to climb. The top construction work platform can only move upward relative to the guide rail. The base support platform, as the supporting work platform, remains stationary. The brackets of the automatic telescopic brackets of the base support platform are supported in the reserved openings in the wall. Step 2: The climbing drive mechanism rotates forward, driving the top construction platform to rise 2-4cm and then stop. The automatic telescopic device of the bracket of the top construction platform retracts, allowing the bracket to detach from the reserved opening on the wall. Step 3: The climbing drive mechanism continues to rotate forward, driving the top construction platform to continue climbing; Step 4: When the top construction platform approaches the target position, the legs of the automatic extension device of the top construction platform extend outward. During the upward climbing process of the top construction platform, the legs of the automatic extension device of the top construction platform automatically extend into the reserved opening on the wall, the climbing drive mechanism stops running, so that the top construction platform is supported on the wall, and the climbing work of the top construction platform is completed. Step 5: Switch the two-way fall protection automatic switching device to downward mode. The base support platform is ready to climb. The base support platform and the guide rail can only move upward relative to the top construction work platform. Step 6: The climbing drive mechanism reverses, causing the base support platform to move upwards by 2-4cm and then stop. The brackets of the automatic extension and retraction device of the brackets of the base support platform retract, so that the brackets are no longer supported in the reserved openings in the wall. Step 7: The climbing drive mechanism reverses, causing the base support platform to continue climbing. The legs of the automatic extension and retraction device of the base support platform extend outward. During the upward climbing process of the base support platform, the legs of the automatic extension and retraction device of the base support platform automatically extend into the corresponding reserved openings on the wall. The climbing drive mechanism stops running, so that the base support platform is supported on the wall, completing the climbing work of the base support platform. Repeat steps 1 to 7 to allow the top construction platform and the base support platform to alternately climb up the wall.

[0018] As can be seen from the above-disclosed technical solutions, the beneficial effects of the present invention compared with the prior art are as follows: In summary, the present invention provides a fully automatic construction lifting platform system and method for climbing and supporting, comprising a base support platform, a guide rail, four climbing drive devices, several automatic telescopic bracket devices, a top construction work platform, and four bidirectional automatic fall protection switching devices. The climbing drive device employs a climbing drive mechanism, a screw, and ball nuts. Through the helical pair transmission between the screw and ball nuts, friction loss can be reduced, achieving smooth platform lifting and lowering (transmission efficiency ≥90%). By employing the bidirectional automatic fall protection switching devices, the relative movement direction between the top construction work platform and the guide rail can be limited, ensuring the safety of the fully automatic construction lifting platform system for climbing and supporting.

The top construction platform 5 prepares to climb. The top construction platform 5 can only move upward relative to the guide rail 2. The base support platform 1, as the supporting platform, remains stationary. The brackets of the automatic extension and retraction device 4 of the base support platform 1 are supported in the reserved openings on the wall 7. Figure 22 As shown; Step 2: The climbing drive mechanism 3 rotates forward, driving the top construction platform 5 to rise 2~4cm and then stop. The automatic telescopic device 4 of the bracket of the top construction platform retracts, causing the bracket to detach from the reserved opening on the wall 7. Step 3: The climbing drive mechanism 3 continues to rotate forward, driving the top construction platform 5 to continue climbing; Step 4: When the top construction platform 5 approaches its target position, the legs of the automatic extension device 4 of the top construction platform 5 extend outwards. During the upward climbing process of the top construction platform 5, the legs of the automatic extension device 4 automatically extend into the pre-reserved opening in the wall 7. The climbing drive mechanism 3 stops operating, allowing the top construction platform 5 to be supported on the wall 7, thus completing the climbing operation of the top construction platform 5. Figure 23 As shown; Step 5: Switch the two-way fall protection automatic switching device 6 to the downward mode, and the base support platform 1 is ready to climb. The base support platform 1 and the guide rail 2 can only move upward relative to the top construction work platform 5. Step 6: The climbing drive mechanism 3 reverses, causing the base support platform 1 to move upwards by 2-4cm and then stop. The brackets of the automatic extension and retraction device 4 of the brackets of the base support platform 1 retract, so that the brackets are no longer supported in the reserved openings on the wall 7. Step 7: The climbing drive mechanism 3 reverses, causing the base support platform 1 to continue climbing. The legs of the automatic extension and retraction device 4 of the base support platform 1 extend outwards. During the upward climbing process of the base support platform 1, the legs of the automatic extension and retraction device 4 of the base support platform 1 automatically extend into the corresponding reserved openings on the wall 7. The climbing drive mechanism 3 stops operating, allowing the base support platform 1 to be supported on the wall 7, completing the climbing operation of the base support platform 1. Figure 24 As shown; Repeat steps 1 to 7 to achieve the alternating ascent of the top construction platform 5 and the base support platform 1 along the wall 7.
