Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building engineering, and more particularly to a telescopic arm rod hanging basket construction device and a construction method. BACKGROUND

[0002] In the construction of high-rise and super high-rise building outer walls, curtain wall installation, cleaning and maintenance, etc., a hanging basket system suspended from the top of the building is often used. The cantilever arm rod of the traditional hanging basket system is of fixed length structure, and its working radius is determined at the time of installation.

[0003] When the construction is carried out to the part of the building facade with advancing and retreating changes, such as encountering obstacles such as balconies, sunshields, facade modeling, etc. or needing to work inside the cavity, the existing fixed length arm rod cannot meet the new working surface requirements. Therefore, the construction personnel must lower the hanging basket to the ground or platform, disconnect the hanging basket from the lifting mechanism, manually disassemble the cantilever arm rod system in the air, replace the arm rod of different lengths, and then reinstall, fix and debug the whole system.

[0004] This process not only takes a long time (usually 2 to 3 hours of interruption for a single adjustment), but more seriously, the workers are in a high-risk environment when disassembling and installing the arm rod, which is one of the major safety hazards. At the same time, frequent disassembly and assembly operations are also prone to wear and fatigue of the connecting parts (such as bolts and pins), further reducing the overall reliability of the system.

[0005] Therefore, how to provide a hanging basket construction device that can adjust the horizontal working position of the hanging basket in real time and safely without interrupting the work is a problem that needs to be solved by those skilled in the art. SUMMARY

[0006] Therefore, the present application provides a telescopic arm rod hanging basket construction device and a construction method, which aims to solve the above technical problems.

[0007] In order to achieve the above purpose, the present application adopts the following technical solutions:

[0008] A telescopic arm rod hanging basket construction device, comprising an upper structure body, and at least one suspension system installed on the upper structure body, the suspension system comprising:

[0009] a support bracket, the bottom end of the support bracket being fixed to the top surface of the upper structure body;

[0010] a fixed arm rod, the fixed arm rod being vertically fixed to the top end of the support bracket;

[0011] A telescopic driving assembly, which comprises a driving mechanism mounted at one end of the fixed arm rod and a telescopic arm rod in transmission connection with the driving mechanism, the telescopic arm rod extending along the axial direction of the fixed arm rod;

[0012] A lifting mechanism, one end of which is mounted on the basket and the other end is fixedly connected with the telescopic arm rod;

[0013] The driving mechanism can drive the telescopic arm rod to extend or retract relative to the fixed arm rod to drive the basket to adjust the horizontal working position.

[0014] Through the above technical scheme, the telescopic arm rod is directly driven by the driving mechanism to extend or retract, and the stepless, dynamic and real-time adjustment of the horizontal working position of the basket is realized. The cumbersome process of lowering the basket to the ground, disassembling, replacing the arm rod and reassembling and debugging in the traditional method is avoided, and the work efficiency is improved. One set of basket device can flexibly adapt to complex and changeable building facade (such as concave-convex, setback, modeling, etc.), and the universality and utilization rate of the equipment are significantly improved.

[0015] Preferably, in the above telescopic arm rod basket construction device, an anti-overturning stability assembly is further included, the anti-overturning stability assembly comprises a support rod and a constraint cable, the bottom end of the support rod is fixed on the upper surface of the fixed arm rod, and the two ends of the constraint cable are fixed on the two ends of the fixed arm rod, and the middle part of the constraint cable is wound around the top end of the support rod. The component forms a stable internal force balance system through the support rod and the constraint cable, effectively transmits the moment generated by the cantilever structure back to the main structure, prevents the whole device from being unstable and overturning, provides crucial stability guarantee for the core power telescopic function, and enables the telescopic action to be safe and stable even under full load or strong wind conditions, thereby improving the rigidity and reliability of the whole system.

[0016] Preferably, in the above telescopic arm rod basket construction device, a pulley is mounted at the top end of the support rod, and the middle part of the constraint cable is wound around the pulley, and the two ends of the constraint cable are fixed on the two ends of the fixed arm rod, respectively. By setting the pulley at the top end of the support rod, the sliding friction between the constraint cable and the support rod is changed into rolling friction, the wear of the cable during the telescopic process is reduced, the strength of the cable is prevented from being reduced and damaged due to friction, the rolling friction makes the force transmission more smooth, the energy loss is reduced, the instantaneity and effectiveness of the anti-overturning effect are ensured, and the operation of the whole system is more efficient and stable.

[0017] Preferably, in the telescopic arm pole hanging basket construction device, an anchoring assembly is further included, the anchoring assembly includes a lower main body structure and an anchoring cable, the lower main body structure is located below the upper main body structure, one end of the anchoring cable is fixedly connected with the lower main body structure, and the other end is fixedly connected with the fixed arm pole away from one end of the telescopic arm pole. A separate vertical load transmission path is established, most of the weight of the hanging basket, load and lifting mechanism is directly anchored to the lower stable foundation, instead of being borne by the top suspension system, the vertical bending moment and shear force borne by the support bracket and the fixed arm pole are reduced, the top structure mainly bears the torque and horizontal force, the stress distribution of the overall structure is optimized, and the overall stability, safety and carrying capacity of the device are improved.

The anchoring plate serves as a firm transition member and provides a reliable and durable connection point for the anchoring cable. It can effectively disperse the large concentrated stress brought by the cable and prevent damage such as crushing and cracking of the lower main body structure (such as a concrete floor).

[0019] Preferably, in the telescopic arm pole hanging basket construction device, the driving mechanism is a linear driving mechanism.

[0020] Preferably, in the telescopic arm pole hanging basket construction device, the linear driving mechanism is an electric driving mechanism, a hydraulic driving mechanism or a pneumatic driving mechanism.

[0021] Preferably, in the telescopic arm pole hanging basket construction device, the number of suspension systems is two, the two suspension systems are symmetrically arranged on the upper structure main body, and the driving mechanisms of the two suspension systems operate synchronously. The use of double suspension systems arranged symmetrically and operating synchronously can smoothly and evenly hang the hanging basket from two points, effectively overcoming the problems of unbalanced load, twisting and shaking that may be caused by a single system; at the same time, it ensures that the hanging basket always maintains a horizontal posture during horizontal telescoping, significantly improves the stability, safety and operation positioning accuracy of the operation, and is particularly suitable for large, wide or heavy load hanging basket operation scenarios.

[0025] Wherein, the step S1 and the step S2 are adjusted according to the construction requirement, the step S1 can be directly completed in the air under the condition of the basket load, without needing to be lowered to the ground or unloaded.

[0026] Preferably, in the construction method of the telescopic arm rod basket construction device, in the step S1, the driving mechanism is controlled to operate in a wireless remote control mode. Through the wireless remote control mode, the operator can complete all adjustment operations in a safe area such as the ground or the building interior, completely avoiding the risk of operating the equipment in a shaking high-altitude basket or a dangerous edge position, realizing man-machine separation and intrinsic safety.
