Description

Technical Field

[0001] This invention relates to the field of curtain wall construction technology, specifically to a curtain wall construction cable-stayed scaffold device and its usage method. Background Technology

[0002] Stone curtain walls, as an important form of modern building facade decoration, are widely used in high-rise and super high-rise buildings due to their natural texture and excellent durability. In the installation and maintenance of stone curtain walls, cable-stayed scaffolding, with its flexible structure and strong adaptability, has become an indispensable construction platform. However, the risk of collision between the scaffolding and the curtain wall has always been a problem in this field when using cable-stayed scaffolding for stone curtain wall construction. Stone itself is hard and brittle, with poor impact resistance; once impacted, it is prone to developing hidden cracks or defects, and repairs are difficult and costly.

[0003] Currently, although some buffer devices for use with cable-stayed scaffolds are disclosed in the existing technology, most of them are composed of buffer elements such as rubber pads and springs and only have a single buffer energy dissipation method. The buffering effect is relatively limited. Secondly, during continuous use, the buffer elements will gradually become fatigued or aged due to repeated impacts, resulting in performance degradation. However, the existing technology lacks corresponding detection methods to assess this performance change. Operators cannot know whether the buffer device is currently in an effective working state, nor can they determine whether it needs maintenance or replacement, making it difficult to provide data support for accurate equipment maintenance. Furthermore, the reasons for collisions between suspended platforms and stone curtain walls are varied, and may be due to improper operation by workers or environmental wind disturbances. The impacts caused by these two factors differ in frequency and force, and have different guiding significance for construction management. However, most of the existing publicly available buffer devices can only detect the occurrence of a collision, but cannot distinguish the source of the collision, making it difficult to provide data support for optimizing construction specifications and developing targeted wind protection plans. Summary of the Invention

[0004] This invention provides a cable-stayed scaffolding device for curtain wall construction and its usage method, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a curtain wall construction cable-stayed scaffold device, comprising a scaffold, a control cabinet installed inside the scaffold, and composite branch pipes detachably installed on both sides of the front end of the scaffold. Damping buffer components communicating with the space within the composite branch pipes are installed at the top and bottom of the composite branch pipes. A piston buffer assembly and a pressure detection component are fitted inside the front end of the scaffold, with the pressure detection component located outside the output structure of the piston buffer assembly. A pressure relief hole is provided at the top of the piston buffer assembly. A conduit is installed between the two composite branch pipes and the piston buffer assembly. During the anti-collision buffering process between the scaffold and the curtain wall, the output structure of the damping buffer component synchronously presses down on the air inside the assembly formed by the composite branch pipes and the conduit. After receiving the airflow impact, the piston buffer assembly releases pressure and dissipates energy while simultaneously pressing down on the pressure detection component. The pressure detection component outputs real-time impact pressure data and generates impact frequency data per unit time.

[0006] Preferably, the damping buffer component includes a buffer guide cylinder, a composite damping rod, and a first piston body. One end of the buffer guide cylinder is fixed to the corresponding end of the composite branch pipe and is spatially connected. One end of the composite damping rod and the first piston body are both snapped into the interior of the other end of the buffer guide cylinder. A linkage guide rod is installed between one end of the composite damping rod and the first piston body. A first auxiliary sleeve plate is snapped into the outside of the linkage guide rod and fixedly sleeved in the middle of the buffer guide cylinder.

The bottom of the piston cylinder is fitted with the corresponding end of the guide tube, and a support seat is installed between the front surface of the piston cylinder and the inner wall of the front end of the top of the basket. One end of the composite piston rod is fixed to the middle of the second piston body and is engaged with the inside of the piston cylinder. A second return spring is installed between the surface of the middle part of the composite piston rod and the inner wall of the top of the piston cylinder. The other end of the composite piston rod extends to the outside of the top of the piston cylinder, and the end of the other end of the composite piston rod is set as a spherical structure.

[0009] Preferably, the pressure relief hole is located on the top side wall of the piston cylinder and communicates with the internal space of the piston cylinder. A second auxiliary sleeve plate, which is fixedly fitted inside the piston cylinder, is snapped onto the outer side of the middle part of the composite piston rod. The interior of the second auxiliary sleeve plate is provided with several clearance grooves. The pressure detection component includes a pressure sensor and an auxiliary frame. The sensing surface at the bottom of the pressure sensor is in contact with the end surface of the other end of the composite piston rod. The outer side of the pressure sensor is fitted with an auxiliary frame plate installed on the top of the piston cylinder. The interior of the auxiliary frame plate is provided with several ventilation grooves.

[0010] Preferably, the control cabinet is equipped with a control module electrically connected to the pressure sensor, and an anemometer electrically connected to the control module is installed on the surface of the rear end of the control cabinet. The control module includes a microcontroller unit, a communication unit, a buzzer alarm, and a power supply.

[0011] Preferably, a through-type slide rail is provided on the front surface of the suspended platform, and a transition connection component is provided between the middle part of the composite branch pipe and the front end of the suspended platform. The transition connection component includes a guide plate fitted inside the slide rail, and two arc-shaped elastic clamps in a relative state are installed on the front surface of the guide plate. The two arc-shaped elastic clamps are fitted on the outside of the middle part of the composite branch pipe and can elastically clamp and limit the middle part of the composite branch pipe.

[0012] Preferably, the front end structure of both of the arc-shaped elastic clamps is provided with through holes, and a fastener is provided between the two through holes. The fastener includes a bolt and a nut, and one end of the bolt can be threaded through the two through holes and then connected to the nut to clamp and adjust the two arc-shaped elastic clamps. Two limiting sleeves are fixedly sleeved on the surface of the middle part of the composite branch pipe, and the surfaces of the two limiting sleeves are respectively attached to the top and bottom surfaces of the arc-shaped elastic clamps.

[0013] Preferably, the inner wall of the rear end of the slide rail is provided with slide grooves on both sides, the guide rail plate is snapped into the inside of the slide rail, and a limit component is provided between the rear end of the guide rail plate and the front end structure of the suspended basket. The limit component includes an adjusting screw and a limit nut. One end of the adjusting screw passes through the slide groove and is then threadedly connected to the limit nut.

[0014] A cable-stayed scaffolding device for curtain wall construction and its usage method include the following operating steps: S1. The control module collects the pressure data output by the pressure sensor after a single impact and records the number of times the pressure sensor outputs pressure data per unit time during the buffering and anti-collision process of the suspended platform by the combination of damping buffer component and piston buffer assembly. At the same time, the wind speed data detected by the anemometer is also transmitted to the control module. Subsequently, the control module transmits all data to the ground monitoring station through the communication unit. S2. The ground monitoring station analyzes the number of impacts per unit time, the change in pressure data per unit time, and the change in wind speed data per unit time to determine the type of impact, as detailed below. The first scenario is that if the number of impacts is frequent and the impact intensity is lower than the preset abnormal threshold within a unit of time, and the wind speed data shows that the airflow in the working environment is stable, then the abnormal cause will be judged as the construction personnel being too close to the area of ​​the suspended platform near the curtain wall during operation, and the low-speed swaying of the suspended platform due to movement causing it to impact the curtain wall. The second scenario is that if the number of impacts per unit time is low and the impact intensity is higher than the preset abnormal threshold, and the wind speed data shows that there is a gust of wind in the working environment, then the abnormal cause will be judged as the suspended scaffold being blown by the gust of wind, which will cause the suspended scaffold to impact the curtain wall at a relatively high speed. The third type is when the number of impacts per unit time is high and the impact intensity is higher than the preset abnormal threshold. If the wind speed data shows that there is a continuous gust phenomenon in the working environment, then the abnormal cause will be judged as the suspended basket being blown by the frequent gust airflow, which will cause the suspended basket to hit the curtain wall at a relatively high speed. Moreover, the sudden continuous gust is likely to be a sign of a strong wind. The ground monitoring station should immediately lower the suspended basket or direct the construction personnel to take emergency evacuation. S3. After assembling the composite branch pipe, damping buffer component, piston buffer assembly, pressure detection component and conduit into a buffer mechanism for the use of the suspended platform, conduct simulated impact experiments, collect pressure-time curves of at least 50 typical impacts, calculate the impulse of each impact, and statistically analyze the average impulse and standard deviation. S4. In actual use, after each impact, the control module transmits all relevant data to the ground monitoring station. The ground monitoring station calculates the impulse of a single real-time impact by analyzing the pressure, time and other relevant data of the single real-time impact. Then, the impulse of the single real-time impact is divided by the average impulse and multiplied by a percentage to obtain the buffer efficiency. S5. Compare the buffer efficiency during a single real-time impact with the preset threshold range, and then make a judgment. Specifically, there are three situations: First, if the buffer efficiency is greater than the preset maximum threshold, it means that the buffering performance of the buffer mechanism is normal; Second, if the buffer efficiency is less than the preset maximum threshold but greater than the preset minimum threshold, it means that the buffering performance of the buffer mechanism has decreased but is still usable, but special attention is needed; Third, if the buffer efficiency is less than the preset minimum threshold, it means that the buffering performance of the buffer mechanism has dropped to a state that cannot meet the usage requirements, and it needs to be replaced in time. S6. In the face of curved curtain walls in reality, adaptive anti-collision protection can be achieved by adjusting the spacing between the two composite branch pipes and the conduits associated with the two composite branch pipes.

[0015] The present invention has the following beneficial effects: 1. The curtain wall construction cable-stayed scaffold device, equipped with multiple damping buffer components and piston buffer assemblies, supported by related composite branch pipes, conduits, and other structures, can form a series buffering effect of damping buffer and piston pressure relief during the collision protection of the scaffold. When the scaffold impacts the curtain wall, the damping buffer components first contact and provide damping buffer protection. Subsequently, the piston buffer assembly and the damping buffer components work together to release the pressure of the damping buffer components through the exhaust port, achieving secondary buffering. This significantly improves the protection effect for the scaffold and the curtain wall. Moreover, this graded buffering method can automatically adjust the damping effect according to the magnitude of the impact energy, providing corresponding dissipation capacity for impacts of different intensities. Furthermore, the secondary buffering provides a safe installation position for the pressure detection components to be laid subsequently.

[0016] 2. The method of using the curtain wall construction cable-stayed scaffold device is to collect pressure data of each impact without interfering with the buffering operation by setting pressure detection components as an auxiliary condition. The impulse is calculated and compared with the benchmark value to obtain the buffering efficiency. When the buffering efficiency is continuously lower than the set threshold, it can be judged that the buffering performance has deteriorated or failed. This allows the operators to understand the working status of the buffering device and provides data reference for equipment maintenance.

[0017] 3. The operation method of this curtain wall construction cable-stayed scaffold device involves using a pressure detection component to monitor and output pressure data, indirectly providing feedback on the number of impacts. Furthermore, by combining and analyzing the number of impacts per unit time, the intensity of each impact, and real-time wind speed data, the source of the impact can be differentiated. Specifically, high-frequency, low-intensity impacts with low wind speeds can be identified as being caused by manual operation; low-frequency, high-intensity impacts with high wind speeds can be identified as being caused by wind disturbances. This differentiation helps analyze risk factors during construction and provides a basis for adjusting work procedures.

[0018] 4. The curtain wall construction cable-stayed scaffold device, with its two composite branch pipes further assembled through two corresponding arc-shaped elastic clamps, fasteners, slides, adjusting screws, and limit nuts, can drive the corresponding damping buffer components to move closer or further apart, or rotate and adjust the damping buffer components, thereby meeting the construction needs of different curtain wall forms and expanding the application range of the overall device.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-5A curtain wall construction cable-stayed scaffold device includes a scaffold 1, a control cabinet 2 installed inside the scaffold 1, and composite branch pipes 3 that can be detachably installed on both sides of the front end of the scaffold 1. The top and bottom of the composite branch pipes 3 are equipped with damping buffer components 4 that communicate with their own space. See Figure 10 The damping buffer component 4 includes a buffer guide cylinder 41, a composite damping rod 42, and a first piston body 43. One end of the buffer guide cylinder 41 is fixed to the corresponding end of the composite branch pipe 3 and is spatially connected. One end of the composite damping rod 42 and the first piston body 43 are both snapped into the interior of the other end of the buffer guide cylinder 41. A linkage guide rod 44 is installed between one end of the composite damping rod 42 and the first piston body 43. A first auxiliary sleeve 46 is snapped into the outside of the linkage guide rod 44 and fixedly sleeved in the middle of the buffer guide cylinder 41. A first return spring 45 is installed between the first auxiliary sleeve 46 and the end face of one end of the composite damping rod 42. Thus, when the composite damping rod 42 inside the damping buffer component 4 contacts the curtain wall and performs reverse damping and buffering displacement in conjunction with the first return spring 45, the composite damping rod 42 will also pass through the linkage guide rod 43. 4 and the first piston body 43 move synchronously, and then squeeze the air in the flow channel space after the three structures of buffer guide cylinder 41, composite branch pipe 3, and conduit 7 are combined, providing extended conditions for further buffering and energy dissipation. The other end of the composite damping rod 42 is set as a hemispherical structure, which can meet the multi-angle contact with the curtain wall while avoiding conical contact impact, thus optimizing the buffering effect. The first return spring 45 is fitted on the outer side of the surface of the first auxiliary sleeve plate 46 and rubs against the surface of the first auxiliary sleeve plate 46 during its own buffering deformation. Considering that the number of collisions in reality is not high, in order to obtain a faster energy dissipation speed during the impact buffering process, the first return spring 45 rubs against the surface of the first auxiliary sleeve plate 46 during the deformation process, and then dissipates energy through friction to accelerate the attenuation of vibration energy. See Figures 3-5 , Figures 7-9 The front end of the suspended basket 1 is fitted with a piston buffer assembly 5 and a pressure detection component 6. The pressure detection component 6 is located outside the output structure inside the piston buffer assembly 5. The top of the piston buffer assembly 5 is provided with a pressure relief hole 9. A conduit 7 is installed between the two composite branch pipes 3 and the piston buffer assembly 5. The piston buffer assembly 5 includes a piston cylinder 51, a second piston body 52, and a composite piston rod 55. The bottom of the piston cylinder 51 is fitted with the corresponding end of the guide tube 7, and a support seat is installed between the front surface of the piston cylinder 51 and the inner wall of the top front end of the basket 1. One end of the composite piston rod 55 is fixed to the middle of the second piston body 52 and is locked inside the piston cylinder 51. A second return spring 56 is installed between the surface of the middle part of the composite piston rod 55 and the inner wall of the top of the piston cylinder 51. The other end of the composite piston rod 55 extends to the outer side of the top of the piston cylinder 51, and the end of the other end of the composite piston rod 55 is set as a spherical structure to ensure good top pressure contact effect. After the piston buffer assembly 5 and the damping buffer component 4 are further combined and linked, the piston buffer assembly 5 can receive the synchronous output air pressure impact of the damping buffer component 4 and release pressure through the exhaust hole while the damping buffer component 4 completes the damping buffer, thus achieving secondary buffering. This graded buffering method can automatically adjust the damping effect according to the magnitude of the impact energy and provide corresponding dissipation capacity for impacts of different intensities. The pressure relief hole 9 is opened on the top side wall of the piston cylinder 51 and communicates with the internal space of the piston cylinder 51. The outer side of the middle part of the composite piston rod 55 is snapped with a second auxiliary sleeve 53 that is fixedly sleeved inside the piston cylinder 51. The interior of the second auxiliary sleeve 53 is provided with several clearance grooves 54. The pressure detection component 6 includes a pressure sensor 61 and an auxiliary frame 62. The sensing surface at the bottom of the pressure sensor 61 is in contact with the end surface of the other end of the composite piston rod 55. The outer side of the pressure sensor 61 is fitted with an auxiliary frame 62 installed on the top of the piston cylinder 51. The interior of the auxiliary frame 62 is provided with several ventilation grooves, thereby providing clearance space for the pressure sensor 61 to continue to be used in the future, allowing for the convection of hot and cold air between its environment and the outside, and extending the service life of the pressure sensor 61. The control cabinet 2 is equipped with a control module that is electrically connected to the pressure sensor 61, and the surface of the rear end of the control cabinet 2 is equipped with an anemometer 8 that is electrically connected to the control module. The control module includes a microcontroller unit, a communication unit, a buzzer alarm and a power supply, thereby meeting the usage requirements for remote transmission and analysis of relevant impact data. During the anti-collision buffering process between the suspended basket 1 and the curtain wall, the output structure of the damping buffer component 4 synchronously presses the air inside the assembly formed by the composite branch pipe 3 and the duct 7. After receiving the airflow impact, the piston buffer assembly 5 releases pressure and dissipates energy while simultaneously pressing the pressure detection component 6. The pressure detection component 6 outputs real-time impact pressure data and generates impact number data per unit time.

[0023] In use, the two composite branch pipes 3 are set up, and the two damping buffer components 4, two conduits 7, piston buffer assembly 5 and pressure detection component 6 connected to the two composite branch pipes 3 respectively form a buffer mechanism that can work in conjunction with the suspended platform 1. Subsequently, during the curtain wall installation work when the suspended platform 1 is supported at high altitude by the existing traction device, the four damping buffer components 4 are located between the suspended platform 1 and the curtain wall. When the suspended platform 1 hits the curtain wall due to wind or human operation error, the composite damping rod 42 inside the four damping buffer components 4 will first contact the surface of the curtain wall and perform damping and buffering displacement under the elastic traction of the corresponding first return spring 45. During the movement, the composite damping rod 42 will drive the first piston body 43 to push the air inside the buffer guide cylinder 41 through the linkage guide rod 44. Then, under the combined transition of the composite branch pipe 3 and the guide pipe 7, the airflow enters the interior of the piston cylinder 51 and pushes the second piston body 52 with upward pressure. Subsequently, the combination formed by the second piston body 52 and the composite piston rod 55 moves upward under the support of the piston cylinder 51, squeezing the air in the top of the piston cylinder 51 and causing it to be discharged from the pressure relief hole 9, thereby performing secondary buffering and energy dissipation. During the movement, the composite piston rod 55 will also press the pressure sensor 61 synchronously, which will then send the pressure data of this press to the control module. This process is repeated, and the four damping buffer components 4, together with the piston buffer assembly 5, provide double buffering and anti-collision for the suspended basket 1 in use, reducing the chance of the curtain wall being damaged and thus reducing construction costs.

[0024] Please see Figures 1-12 A through-type slide rail 10 is opened on the front surface of the suspended platform 1. A transition connection component is provided between the middle part of the composite branch pipe 3 and the front end of the suspended platform 1. The transition connection component includes a guide plate 11 fitted inside the slide rail 10. Two arc-shaped elastic clamps 12 in a relative state are installed on the front surface of the guide plate 11. The two arc-shaped elastic clamps 12 are fitted on the outside of the middle part of the composite branch pipe 3 and can elastically clamp and limit the middle part of the composite branch pipe 3. This ensures the long-term stability of the composite branch pipe 3 and its related structures when used in combination with the suspended platform 1, and also provides the composite branch pipe 3 and its related structures with an adaptive use effect in the face of different operation requirements. Both arc-shaped elastic clamps 12 have through holes at their front ends, and fasteners 13 are provided between the two through holes. The fasteners 13 include bolts and nuts. One end of the bolt can be threaded through the two through holes and then connected to the nut to clamp and adjust the two arc-shaped elastic clamps 12. This maintains the flexibility of the two arc-shaped elastic clamps 12 while ensuring the stable clamping and limiting effect of the two arc-shaped elastic clamps 12 on the composite branch pipe 3. Two limiting sleeves 17 are fixedly sleeved on the surface of the middle part of the composite branch pipe 3. The surfaces of the two limiting sleeves 17 are respectively attached to the top and bottom surfaces of the arc-shaped elastic clamps 12, providing further limiting support for the assembly and connection of the composite branch pipe 3 and the two arc-shaped elastic clamps 12.

[0025] When using it, considering the anti-collision requirements of the suspended platform 1 during the assembly of irregular curtain walls, taking the curved curtain wall with concave ends and convex middle as an example, the following adjustment operations are performed; When the suspended platform 1 is used at a high altitude, it is horizontal to the building wall. This results in a gap between the curved curtain wall (concave at both ends and convex in the middle) and the suspended platform 1, with the sides being narrower and the middle wider. Therefore, to ensure the contact and impact protection effect of the damping buffer component 4, the damping buffer components 4 associated with the two composite branch pipes 3 are adjusted to be tilted away from each other. This ensures that in the event of an impact, the damping buffer component 4 contacts the curtain wall before the suspended platform 1. Based on the operational effect of ensuring impact protection, the adjustment details are as follows: First, loosen the bolts and nuts between the two arc-shaped elastic clamps 12. Then, loosen the composite branch pipe 3 so that the composite branch pipe 3 drives the two corresponding damping buffer components 4 to rotate synchronously. The corresponding conduit 7 uses an elastic tube body, which bends and makes room during the rotation adjustment of the composite branch pipe 3 while maintaining the unobstructed passage between the conduit 7 and the composite branch pipe 3. After the damping buffer component 4 rotates and tilts to a suitable angle, reset the locking bolts and nuts so that the two arc-shaped elastic clamps 12 clamp and limit the composite branch pipe 3 again. Then, the remaining composite branch pipe 3 and its two associated damping buffer components 4 can be adjusted synchronously.

[0026] Please see Figures 1-11 , Figure 13 The slide rail 10 has grooves 14 on both sides of the inner wall at the rear end. The guide plate 11 is snapped into the inside of the slide rail 10. A limit component is provided between the rear end of the guide plate 11 and the front end structure of the suspended basket 1. The limit component includes an adjusting screw 15 and a limit nut 16. One end of the adjusting screw 15 passes through the groove 14 and is then threadedly connected to the limit nut 16.

[0027] When in use, considering another common irregular curtain wall in reality, namely a curtain wall that is concave in the middle and convex on both sides, the distance between it and the suspended platform 1 during the construction process is narrow in the middle and wide on both sides. Therefore, the above-mentioned tilt adjustment of the damping buffer component 4 is no longer sufficient to meet the anti-collision requirements, and the following adjustment is required. Tighten the corresponding limiting nuts 16 at the rear ends of the two guide rail plates 11 to temporarily move the limiting nuts 16 away from the front end structure of the suspended platform 1, thereby temporarily releasing the limiting constraint on the guide rail plates 11. Then, push the two guide rail plates 11 relative to each other, so that the two guide rail plates 11 drive their corresponding composite branch pipes 3, damping buffer components 4 and other structures to move in close proximity. During the movement of the guide rail plates 11, the slide rail 10 provides clearance space for the guide rail plates 11, and the slide groove 14 provides clearance space for the adjusting screw 15 to avoid structural interference. Correspondingly, the guide tube 7 still uses an elastic tube body to deform and make way. After the two damping buffer components 4 have moved to the appropriate position, reset and lock the limiting nuts 16, and re-limit the guide rail plates 11 after the movement and adjustment to ensure the stability of the composite branch pipes 3, damping buffer components 4 and other structures associated with the guide rail plates 11 during the anti-collision use.

[0028] A method for using a cable-stayed scaffolding device for curtain wall construction includes the following operating steps: S1. During the process of the damping buffer component 4 and the piston buffer assembly 5 buffering and anti-collision of the suspended basket 1, the control module collects the pressure data output by the pressure sensor 61 after a single buffering impact and records the number of times the pressure sensor 61 outputs pressure data per unit time. At the same time, the wind speed data detected by the anemometer 8 is also transmitted to the control module. Subsequently, the control module transmits all data to the ground monitoring station through the communication unit. The specific details are as follows: The microcontroller unit in the control module acquires the pressure data transmitted by the pressure sensor 61 to obtain the real-time pressure value. Simultaneously, wind speed data is acquired through the anemometer 8 to obtain real-time wind speed values. ; Set a trigger threshold When the pressure data transmitted by pressure sensor 61 is greater than the trigger threshold If the collision has started, the start time is recorded. The pressure changes of pressure sensor 61 are then continuously monitored, and when the pressure value returns to zero or is less than the trigger threshold... If the collision ends, the end time is recorded. The time interval corresponding to a single impact event is to ; S2. The ground monitoring station analyzes the number of impacts per unit time, the change in pressure data per unit time, and the change in wind speed data per unit time to determine the type of impact, as follows: The physical basis for impulse calculation is that impulse is the integral of force over time, directly reflecting the total change in momentum transferred during the impact. It combines the duration of the impact and the magnitude of the force, and can more accurately characterize the impact energy than a simple pressure peak. Its definition is as follows: ; Numerical calculation method: Since the microcontroller unit collects discrete sampling points, the trapezoidal rule is used for numerical integration. Let the sampling time be... The corresponding pressure value is ,in , The formula for calculating impulse is as follows: ; The above formula divides the area under the pressure curve into multiple small trapezoids, and the summation yields the total impulse. The higher the sampling frequency, the higher the integration accuracy. Therefore, after each impact event, the impulse of this impact is calculated according to the above formula and recorded. Unit time window statistics Using a fixed time window T as the unit, count the total number of impacts N and the average impact intensity within the window. ,in Let i be the impulse and the maximum impact intensity of the i-th impact within the window. The average wind speed inside the window is And the maximum wind speed is The threshold for the maximum number of impacts per unit time is set to... The minimum number of impacts per unit time threshold is set to For example, the maximum safe impact impulse that the design can withstand is The maximum safety impact threshold Set as Minimum safe impact threshold Set as The safe wind speed threshold is set to ; Logical judgment of the cause of the impact. when If this occurs, it indicates that the impact was primarily caused by improper operation by the personnel, and the ground monitoring station will issue a warning. when If this occurs, it indicates that the impact was mainly caused by a brief gust of wind in the work environment. The ground monitoring station will then remind the operators to stand firm and hold on. when This indicates that the impact factor at this time was mainly caused by frequent gusts of wind in the working environment. As frequent gusts are a precursor to strong winds, the ground monitoring station should immediately notify the operators to carry out an emergency descent or other emergency plans.

After assembling the composite branch pipe 3, damping buffer component 4, piston buffer assembly 5, pressure detection component 6 and conduit 7 into a buffer mechanism for the use of the suspended basket 1, conduct a simulated impact test, collect pressure-time curves of at least 50 typical impacts, calculate the impulse of each impact, and statistically analyze the average impulse and standard deviation. The specific settings are as follows: impulse of each impact Calculate the average impulse The formula for calculating buffer efficiency is as follows: ; Set warning threshold Fault threshold ; S4. In actual use, after each impact, the control module transmits all relevant data to the ground monitoring station. The ground monitoring station calculates the impulse of a single real-time impact by analyzing the pressure, time and other relevant data of the single real-time impact. Then, the impulse of the single real-time impact is divided by the average impulse and multiplied by a percentage to obtain the buffer efficiency. The method for calculating impulse is the same as the steps in S2 above; S5. Compare the buffer efficiency during a single real-time impact with a preset threshold range, and then make a judgment. when This indicates that the buffer mechanism is functioning normally during use; when If this continues for more than three times, it indicates that the buffering performance of the buffer mechanism has begun to decline during use. Although it can still be used, special attention is required. when If this continues for more than three times, it indicates that the buffer mechanism is no longer able to meet the anti-collision buffering requirements of item 1. The buzzer alarm will sound immediately, prompting the operator to replace the buffer mechanism in time to reduce losses. S6. In the face of curved curtain walls in reality, adaptive anti-collision protection can be achieved by adjusting the spacing between the two composite branch pipes 3 and the conduits 7 associated with the two composite branch pipes 3. The specific steps are as follows: When facing an arc-shaped curtain wall that is concave at both ends and convex in the middle, perform the following adjustments; When the suspended platform 1 is used at a high altitude, it is horizontal to the building wall. This results in a narrower side and wider center gap between the curved curtain wall (concave at both ends and convex in the middle) and the suspended platform 1. Therefore, to ensure the contact and impact protection effect of the damping buffer component 4, the damping buffer components 4 associated with the two composite branch pipes 3 are tilted away from each other. This ensures that in the event of an impact, the damping buffer component 4 contacts the curtain wall before the suspended platform 1. Based on the operational effect of ensuring impact protection, the adjustment details are as follows: First, loosen the bolts and nuts between the two arc-shaped elastic clamps 12. Then, loosen the composite branch pipe 3 so that the composite branch pipe 3 drives the two corresponding damping buffer components 4 to rotate synchronously. The corresponding conduit 7 uses an elastic tube body. During the rotation adjustment of the composite branch pipe 3, it bends to make room while maintaining the unobstructed channel between the conduit 7 and the composite branch pipe 3. After the damping buffer component 4 rotates and tilts to a suitable angle, reset the locking bolts and nuts so that the two arc-shaped elastic clamps 12 clamp and limit the composite branch pipe 3 again. Then, the remaining composite branch pipe 3 and its two associated damping buffer components 4 can be adjusted synchronously. When facing a curtain wall that is concave in the middle and convex on both sides, the distance between it and the suspended platform 1 during the construction process is narrow in the middle and wide on both sides. Therefore, the above-mentioned tilt adjustment of the damping buffer component 4 is no longer sufficient to meet the anti-collision requirements, and the following adjustment is required. Tighten the corresponding limiting nuts 16 at the rear ends of the two guide rail plates 11 to temporarily move the limiting nuts 16 away from the front end structure of the suspended platform 1, thereby temporarily releasing the limiting constraint on the guide rail plates 11. Then, push the two guide rail plates 11 relative to each other, so that the two guide rail plates 11 drive their corresponding composite branch pipes 3, damping buffer components 4 and other structures to move in close proximity. During the movement of the guide rail plates 11, the slide rail 10 provides clearance space for the guide rail plates 11, and the slide groove 14 provides clearance space for the adjusting screw 15 to avoid structural interference. Correspondingly, the guide tube 7 still uses an elastic tube body to deform and make way. After the two damping buffer components 4 have moved to the appropriate position, reset and lock the limiting nuts 16 to re-limit the guide rail plates 11 after the movement and adjustment, so as to ensure the stability of the composite branch pipes 3, damping buffer components 4 and other structures associated with the guide rail plates 11 during the anti-collision use.

10. A method of using the curtain wall construction cable-stayed scaffolding device as described in claim 6, characterized in that, The following steps are included: S1. During the process of the damping buffer component (4) and piston buffer assembly (5) buffering and anti-collision of the basket (1), the pressure data output by the pressure sensor (61) after a single buffering impact is collected by the control module, and the number of times the pressure sensor (61) outputs pressure data per unit time is recorded. At the same time, the wind speed data detected by the anemometer (8) is also transmitted to the control module. Subsequently, the control module transmits all data to the ground monitoring station through the communication unit. S2. The ground monitoring station analyzes the number of impacts per unit time, the change in pressure data per unit time, and the change in wind speed data per unit time to determine the type of impact, as detailed below. The first type is characterized by frequent impacts within a unit of time, impact intensity below the preset abnormal threshold, and wind speed data showing stable airflow in the working environment. This is judged to be caused by improper operation by construction personnel, resulting in shaking and impacts on the curtain wall. The second type is when the number of impacts per unit time is low, the impact intensity is higher than the preset abnormal threshold, and the wind speed data shows that there are gusts in the working environment, which is judged to be caused by gust airflow that impacts the curtain wall. The third type is when the number of impacts per unit time is high and the impact intensity is higher than the preset abnormal threshold. The wind speed data shows that there is a continuous gust phenomenon in the working environment. It is judged that the frequent gust airflow caused the impact on the curtain wall. The ground monitoring station should immediately lower the suspended basket (1) or direct the construction personnel to take emergency shelter. S3. After assembling the composite branch pipe (3), damping buffer component (4), piston buffer assembly (5), pressure detection component (6) and conduit (7) into a buffer mechanism for the use of the suspended basket (1), conduct simulated impact experiments, collect pressure-time curves of at least 50 typical impacts, calculate the impulse of each impact, and statistically calculate the average impulse and standard deviation. S4. In actual use, after each impact, the control module transmits all relevant data to the ground monitoring station. The ground monitoring station calculates the impulse of a single real-time impact by analyzing the pressure, time and other relevant data of the single real-time impact. Then, the impulse of the single real-time impact is divided by the average impulse and multiplied by a percentage to obtain the buffer efficiency. S5. Compare the buffer efficiency during a single real-time impact with the preset threshold range, and then make a judgment. Specifically, there are three situations: First, if the buffer efficiency is greater than the preset maximum threshold, it means that the buffering performance of the buffer mechanism is normal; Second, if the buffer efficiency is less than the preset maximum threshold but greater than the preset minimum threshold, it means that the buffering performance of the buffer mechanism has decreased but is still usable, but special attention is needed; Third, if the buffer efficiency is less than the preset minimum threshold, it means that the buffering performance of the buffer mechanism has dropped to a state that cannot meet the usage requirements, and it needs to be replaced in time. S6. In the face of curved curtain walls in reality, adaptive anti-collision protection can be achieved by adjusting the spacing between the two composite branch pipes (3) and the conduits (7) associated with the two composite branch pipes (3).
