Description

Technical Field

[0001] The invention belongs to the technical field of connecting passages between climbing frames and tower cranes, and in particular is a modular quick-assembly structure of a tower crane passage based on the construction of a climbing frame for a high-rise building. Background Art

[0002] In the construction of high-rise buildings, tower cranes are important vertical transportation equipment, and the reasonable construction of their passages is crucial to the construction progress and safety. However, there are many problems with the existing tower crane passages: 1. The traditional on-site assembly method is cumbersome: the traditional tower crane channel is usually assembled on the construction site, and each component needs to be installed and debugged one by one, which consumes a lot of time and manpower. In addition, when assembling the tower crane channel on site, it is necessary to frequently use the tower crane for lifting, which makes the tower crane occupied for a long time and cannot efficiently serve other construction links.

[0003] 2. Difficulty in real-time monitoring: Traditional tower crane channels lack real-time monitoring methods for structural status during use.

[0004] Therefore, how to effectively solve the above-mentioned defects is a technical problem that needs to be solved urgently.

[0005] It should be particularly noted that the above technical information is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as admitting or implying in any form that the above technical information constitutes the prior art already known to those skilled in the art. Summary of the invention

[0006] In view of the deficiencies in the above-mentioned background technology, the present invention proposes a modular quick-assembly structure of a tower crane channel based on high-rise building climbing frame construction to solve the problems of low construction efficiency, great safety hazards and lack of intelligent monitoring existing in the prior art.

[0007] The technical solution of this application is: The modular quick-assembly structure of the tower crane channel based on the high-rise building climbing frame construction includes a detachable and connected channel standardized unit module, and the channel standardized unit module is connected to the intelligent monitoring system. The intelligent monitoring system includes stress sensors, inclinometers, and early warning modules that are all connected to the construction management platform.

[0008] Furthermore, the channel standardization unit module includes a channel support keel connected by an intelligent connection structure, the channel support keel is detachably connected to the guardrail, and an adjustable support structure is provided in the channel standardization unit module.

[0009] Furthermore, the adjustable support structure includes a telescopic rod for supporting dynamic adaptation of the channel width and an angle adjustment mechanism for adjusting the inclination angle of the channel.

[0010] Further, the intelligent connection structure includes a plug - type connector and a snap - type positioning guide groove self - locking device, and the snap - type positioning guide groove self - locking device includes a spring - driven snap and a redundant safety bolt.

[0011] Further, anti - slip grilles and anti - fall nets are provided on the channel support keel.

[0012] Further, the guardrail is foldable. After the guardrail is unfolded, it forms a closed channel protection structure, and the guardrail works together with the anti - slip grilles and the anti - fall nets.

[0013] Further, the stress sensors are arranged at the key nodes of the channel to monitor the stress change of the structure in real time. The stress sensors adopt high - precision patch - type resistance strain gauges with an accuracy of ±0.1%, and transmit the data to the construction management platform in real time.

[0014] Further, the inclinometer selects a MEMS three - axis inclinometer with a measuring range of ±30° and a resolution of 0.01°.

[0015] Further, when the data monitored by the stress sensors exceeds the preset threshold or the inclination detected by the inclinometer exceeds the preset threshold, the warning module immediately triggers an audible and visual alarm and sends a text message to the management personnel at the same time.

[0016] Further, the construction management platform supports BIM model pre - assembly simulation and RFID tag tracking module status.

[0017] The specific beneficial effects of the present invention include: 1. The construction efficiency is improved. By pre - fabricating standardized unit modules in the factory and only requiring quick assembly on site, the on - site construction time is greatly reduced. Compared with the traditional method, the construction time of a single - layer channel is shortened from several hours originally to within 30 minutes by 2 - 3 people, and the installation time is shortened by about 70%, significantly improving the construction efficiency.

[0018] 2. The application of the intelligent interface system enables quick and accurate module docking, reduces the adjustment time caused by docking errors, and further improves the assembly speed. At the same time, since the on - site construction time is reduced, the occupancy time of the tower crane is also correspondingly reduced by about 50%, enabling the tower crane to serve other construction links more efficiently and accelerating the overall construction progress.

[0019] 3. The safety performance during the use of the channel is enhanced. The design of the multiple protection structures enables the wind - resistance grade of the tower crane channel to reach level 12, and the bearing capacity ≥1.5 tons per square meter. Compared with the traditional channel structure, both the wind - resistance ability and the bearing capacity have been greatly improved. This effectively improves the stability of the channel in bad weather and under heavy loads, and reduces the risk of safety accidents caused by structural damage.

[0020] 4. The comprehensive application of protective facilities such as anti-slip gratings, anti-fall nets, and folding guardrails provides all-round safety protection for construction workers. The anti-slip gratings effectively reduce the risk of construction workers slipping; the anti-fall nets can reliably intercept the fall of people and objects; while forming a closed protection space, the folding guardrails have sufficient strength and stability. The combined effect of these measures reduces the accident rate by more than 90% compared with traditional structures, providing strong protection for the lives of construction workers.

[0021] 5. It can improve the versatility and adaptability of the passage. The universal interfaces reserved at the connection nodes enable this tower crane passage to be compatible with the installation requirements of attached climbing frames, cantilevered climbing frames, and mainstream tower crane brands. Regardless of the type of climbing frame and tower crane used at the construction site, the tower crane passage of the present invention can be conveniently installed and used without complex modification and adjustment, greatly improving the versatility and application scope of the product, and reducing the construction cost and difficulty.

[0022] 6. The adjustable support system can support the dynamic adaptation of the passage width (0.8 - 1.5 meters) and height (3 - 5 meters), as well as the adjustment of the tilt angle of ±15°. This enables the tower crane passage to flexibly adjust its own size and angle according to the structural characteristics of different buildings, the installation deviation of the climbing frame, and the actual use requirements, better adapting to various complex construction environments and improving the adaptability and flexibility of the product.

[0023] 7. It realizes intelligent management. The intelligent monitoring system can real-time monitor the stress and tilt angle data of the passage by embedding stress sensors and inclinometers at key nodes, and transmit these data to the construction management platform. Managers can understand the status of the passage at any time through the platform and promptly discover potential safety hazards. The setting of the warning module can quickly issue an alarm when the monitored data exceeds the preset threshold, notify relevant personnel to take measures, realizing the timely warning and handling of safety hazards and effectively avoiding the occurrence of safety accidents.

[0024] 8. The BIM model pre-assembly simulation and RFID tag tracking module status functions supported by the construction management platform realize the digital management of the entire life cycle of the tower crane passage from design, installation to use and maintenance. The BIM model pre-assembly simulation helps to optimize the construction plan and improve the installation quality; the RFID tag tracking facilitates the management and maintenance of the module, reasonably arranges the use and replacement of the module, and improves the service life and management efficiency of the equipment.

[0033] Technologies, methods, and devices known to those of ordinary skill in the relevant fields may not be discussed in detail, but where appropriate, the corresponding technologies, methods, and devices should be regarded as part of the specification.

[0034] The modular quick - installation structure of the tower crane passage based on the high - rise building climbing frame construction includes detachably connected standardized unit modules of the passage. The standardized unit modules of the passage are connected to an intelligent monitoring system, and the intelligent monitoring system includes a stress sensor, an inclinometer, and a warning module, all of which are connected to the construction management platform.

[0035] On the basis of the above - mentioned implementation manner, as a preferred implementation manner, the standardized unit module of the passage includes passage support keels connected through an intelligent connection structure. The passage support keels are detachably connected to the guardrail, and an adjustable support structure is provided in the standardized unit module of the passage.

[0036] Specifically, the passage support keel is the main load - bearing structure of the tower crane passage and is made of high - strength aluminum alloy or composite steel. High - strength aluminum alloy has the advantages of light weight, high strength, and corrosion resistance; composite steel combines the advantages of different materials and can meet different usage requirements while ensuring strength. The weight of a single module is controlled within ≤200 kg, which is convenient for tower crane hoisting and on - site installation operations.

[0037] The guardrail adopts a folding design. After unfolding, its height is ≥ 1.2 meters, which can provide reliable protection for construction workers and prevent people from falling. After closing, the volume is reduced by 60%, which is convenient for saving space during transportation and storage, and reducing transportation costs and storage space requirements. The material and structure of the guardrail are carefully selected and designed, with sufficient strength and stability to withstand certain external force impacts.

[0038] On the basis of the above embodiments, as a preferred embodiment, the adjustable support structure includes a telescopic rod for supporting the dynamic adaptation of the channel width and an angle adjustment mechanism for adjusting the inclination angle of the channel.

[0039] Specifically, the telescopic rod built into the module is used to support the dynamic adaptation of the channel width, and its working range is 0.8 - 1.5 meters. The telescopic rod adopts an advanced mechanical or hydraulic drive structure, with good telescopic performance and load-bearing capacity. During the construction process, the channel width can be conveniently adjusted according to actual needs to adapt to different building structures and construction requirements. The angle adjustment mechanism realizes ±15° inclination angle adjustment through worm and worm gear transmission. Worm and worm gear transmission has the advantages of large transmission ratio, compact structure, good self-locking performance, etc., and can accurately adjust the inclination angle of the channel. When the climbing frame has a certain inclination or installation deviation, the channel can be adjusted in time through the angle adjustment mechanism to ensure good connection and normal use between the channel and the climbing frame, improving the adaptability and stability of the structure.

[0040] On the basis of the above embodiments, as a preferred embodiment, the intelligent connection structure includes a plug-in connector and a snap-in positioning guide groove self-locking device, and the snap-in positioning guide groove self-locking device includes a spring-driven snap and a redundant safety bolt.

[0041] Specifically, the modules are quickly docked through the plug-in connector. The plug-in connector is made of high-strength materials, with good wear resistance and fatigue resistance. Its design dimensions are precise, and it can quickly fix the module position after insertion, ensuring the stability of the connection. The snap-in positioning guide groove used in conjunction with the plug-in connector can provide accurate positioning for the plug, ensuring that the module docking error is controlled within a range of less than 2 millimeters. The structure of the snap-in positioning guide groove is ingeniously designed, which can not only guide the plug to accurately insert, but also provide a certain clamping force after the plug is inserted, enhancing the reliability of the connection.

[0042] The self-locking device set at the interface is a key part of the intelligent interface system. The self-locking device includes a spring-driven buckle and a redundant safety bolt, which requires double unlocking operations. After the bolt is inserted in place, the spring-driven buckle can automatically lock to prevent the bolt from loosening; the redundant safety bolt provides additional safety protection. It can only be unlocked when specific operations (press the buckle first and then rotate the safety bolt) are performed simultaneously, effectively avoiding module separation caused by accidental collisions or other reasons, and ensuring the safety and stability of the tower crane passage during use.

[0043] Based on the above implementation, as a preferred implementation, anti-slip gratings and anti-fall nets are provided on the channel support keel. The anti-slip gratings integrated on both sides of the channel have a special anti-slip treatment on their surfaces, such as diamond patterns or matte treatments, to increase friction, and the friction coefficient is ≥0.6. The aperture of the anti-slip gratings is ≤10mm, which can effectively prevent construction workers from slipping and avoid small tools or sundries from falling. Its material is strong and durable, and can withstand various abrasions and pressures during construction. The anti-fall net is made of high-density polyethylene woven net, and the mesh size is ≤20mm, with high strength and toughness, and the tensile strength is ≥50kN / m. The anti-fall net is installed on both sides of the channel, which can effectively intercept the fall of personnel and objects, providing an important safety line for construction workers.

[0044] Based on the above implementation, as a preferred implementation, the guardrail is foldable. After the guardrail is unfolded, it forms a closed channel protection structure, and the guardrail acts together with the anti-slip gratings and the anti-fall nets. The foldable guardrail forms a closed channel protection structure after unfolding, and acts together with the anti-slip gratings and anti-fall nets to further improve the safety of the channel. Its wind resistance rating reaches level 12, and it can withstand strong wind forces, still ensuring the safety of construction workers in strong wind weather. The design of the foldable guardrail also considers the operation convenience of construction workers, and is convenient for unfolding and closing operations without affecting use.

[0045] Based on the above implementation, as a preferred implementation, the stress sensors are set at the key nodes of the channel to monitor the stress change of the structure in real time. The stress sensors use high-precision patch-type resistance strain gauges with an accuracy of ±0.1%, and transmit the data to the construction management platform in real time. By analyzing these data, problems such as stress concentration or overload of the structure can be detected in time, and measures can be taken in advance to avoid structural damage and safety accidents.

[0046] On the basis of the above embodiments, as a preferred embodiment, the inclinometer is selected as a MEMS triaxial inclinometer sensor with a measuring range of ±30° and a resolution of 0.01°. It can monitor the inclination angle of the channel in real time. When the channel shows abnormal inclination, it will timely feedback the data to the construction management platform. This is of great significance for timely discovering the inclination problem of the channel during use and preventing safety accidents caused by excessive inclination.

[0047] On the basis of the above embodiments, as a preferred embodiment, the early warning module in the intelligent monitoring system is an important link to ensure safety. When the data monitored by the stress sensor exceeds the preset threshold (such as stress ≥ 80% of the design value), or when the inclinometer detects abnormal inclination (>5°), the early warning module will immediately trigger an audible and visual alarm and send a text message to the management personnel at the same time. The audible and visual alarm can timely remind the construction personnel to pay attention to safety on site, while the text message notification ensures that the management personnel can obtain the abnormal information immediately no matter where they are, and make decisions and arrange treatment measures in time.

[0048] On the basis of the above embodiments, as a preferred embodiment, the construction management platform supports the pre-assembly simulation of the BIM model and the status tracking of the RFID tag module. The construction management platform is the core of the entire intelligent monitoring system. It can not only receive the real-time monitoring data from the stress sensor and the inclinometer, but also support the pre-assembly simulation of the BIM model and the status tracking of the RFID tag module. Through the pre-assembly simulation of the BIM model, the assembly process of the tower crane channel can be virtually simulated before construction, and possible problems such as interference between modules and unreasonable installation sequence can be discovered in advance and optimized and adjusted, so as to improve the efficiency and accuracy of on-site installation. By using the RFID tag to track the module status, information such as the usage times, maintenance records, and location of each module can be understood in real time, realizing the digital management of the entire life cycle of the module. This helps to reasonably arrange the usage and maintenance plans of the modules, timely replace the modules that are about to reach the service life or are damaged, and ensure the overall safety and reliability of the tower crane channel.

[0049] The details not elaborated in the present invention are all well-known conventional technical means in the art.

[0050] The above content shows and describes the basic principles, main features and the beneficial effects of the present invention. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
