[0038] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0039] like Figures 1 to 3 As shown in the illustration, this embodiment provides an aerial docking device for suspended scaffolds used in curtain wall construction. This device is designed to address the problem of suspended scaffold platforms being unable to be assembled and docked on the ground during curtain wall construction. Due to the complex structure of curtain walls, limitations imposed by safety passage ceilings and construction elevator railings at construction sites, suspended scaffolds often cannot be assembled and docked on the ground, posing safety hazards as they are suspended in the air. This device utilizes the structural characteristics of curtain walls to design an aerial docking system, ensuring the safe docking of the suspended scaffold after installation and use. The aerial docking device can be used for personnel transport and material transport, meeting the needs of construction operations.

[0040] The aerial docking device for curtain wall construction includes a horizontal support frame 1, an inclined support beam 2, a horizontal support platform 3, and a guardrail 4. The horizontal support frame 1 is fixed to the wall 5 of the building and can optionally be set at a position above the second floor to ensure that the suspended platform of the scaffold can be safely docked. Being above the second floor avoids interfering with ground operations and, given the relatively low height, facilitates the transport of materials.

[0041] In this embodiment, the bottom of the horizontal support frame 1 is connected to multiple inclined support beams 2. The inclined support beams 2 are fixed to the building structure by fixing plates and expansion bolts to ensure the stability of the entire device. A guardrail 4 is installed on the horizontal support platform 3. The height of the guardrail 4 is higher than that of the suspended platform of the basket to prevent the basket from accidentally slipping when it is stopped.

[0042] As a specific example of this embodiment, the horizontal support frame 1 can be composed of multiple horizontal support beams 6 arranged side by side. The horizontal support beams 6 are connected to longitudinal support beams 7 by welding, forming a stable frame structure. The horizontal support frame 1 is firmly fixed to the wall of the building, positioned above the second floor. At the bottom of the horizontal support frame 1, multiple diagonal support beams 2 are connected to enhance overall stability. A horizontal support platform 3 is installed on the horizontal support frame 1. The cross-sectional area of ​​the horizontal support platform 3 is larger than the cross-sectional area of ​​the suspended platform, ensuring stable placement of the suspended platform. The first end of the diagonal support beam 2 is connected to a fixing plate with multiple fixing holes. The fixing plate is fixed to the building structure by cooperating with expansion bolts. The second end of the diagonal support beam 2 is connected to the horizontal support frame 1 by welding, ensuring a strong connection.

[0043] In this embodiment, the guardrail 4 is installed around the horizontal support platform 3 and consists of multiple evenly distributed posts 8. Horizontal angle steel 9 is welded between the posts 8. A color steel kick plate 10 is also installed at the bottom of the guardrail 4. The color steel kick plate 10, installed at the bottom of the guardrail 4, can prevent debris from falling from the edge of the horizontal support platform 3, serving both a protective and warning function. This reduces safety accidents caused by falling debris at the construction site and reminds workers to pay attention to the edge area.

[0044] In this embodiment, the height of guardrail 4 is higher than the height of the suspended platform, ensuring safety from all angles when the suspended platform is docked. If necessary, color steel plates can be installed on the entire guardrail for additional protection.

[0045] One end of the transverse support beam 6 of the horizontal support frame 1 is connected to a connecting plate, which is fixed to the wall by expansion bolts, further enhancing the connection stability between the horizontal support frame 1 and the wall. The other end of the transverse support beam 6 is connected to a longitudinal angle steel, which is attached to the bottom of the horizontal support platform 3 and located at the end position, providing additional support force to the horizontal support platform 3 and preventing deformation of the horizontal support platform 3 under stress. This improves the stability and load-bearing capacity of the entire device.

[0046] In this embodiment, the installation position of the horizontal support frame 1 on the building wall can be determined according to the building structure and the requirements of the suspended platform, and a suitable position above the second floor can be selected. The installation holes for the expansion bolts are marked on the wall, and holes are drilled using an electric drill. The fixing plate of the inclined support beam 2 is fixed to the building wall using expansion bolts, ensuring that the fixing plate is securely installed. According to the design requirements, the transverse support beam 6 and the longitudinal support beam 7 are welded and assembled into the frame structure of the horizontal support frame 1.

[0047] The assembled horizontal support frame 1 is connected to the second end of the inclined support beam 2 by welding. At the same time, the connecting plate of the horizontal support frame 1 is fixed to the wall with expansion bolts to complete the installation of the horizontal support frame 1.

[0048] Based on the dimensions of the horizontal support frame 1, fabricate a horizontal support platform 3 of appropriate size. Install the horizontal support platform 3 onto the horizontal support frame 1, ensuring a secure installation. This can be done by welding or bolting.

[0049] Mark the installation positions of the posts 8 around the horizontal support platform 3. Install and fix the posts 8 according to the marked positions, which can be done by welding or bolting to the horizontal support platform 3. Weld horizontal angle steel 9 between the posts 8 to form a complete guardrail 4 structure. Install color steel kick plate 10 at the bottom of the guardrail 4 and fix it with bolts or rivets.

[0050] The longitudinal angle steel is installed at the end of the bottom of the horizontal support platform 3 and is firmly connected to the transverse support beam 6, which can be done by welding.

[0051] In this embodiment, the horizontal and vertical support beams can be made of channel steel to meet the strength requirements of the horizontal support frame for supporting the suspended platform. For example, No. 8 or No. 10 channel steel can be used, with the channel steel specifications determined according to actual load-bearing requirements. The diagonal support beams can be made of angle steel, such as No. 5 angle steel, to provide effective diagonal support for the horizontal support frame. The horizontal support platform can be made of steel plate, with a thickness of 3-5mm, to ensure sufficient strength and load-bearing capacity. The guardrail posts can be made of steel pipe, such as steel pipe with a diameter of 40mm or 50mm. The horizontal angle steel can be No. 4 angle steel, used to connect the posts and enhance the overall stability of the guardrail. The color steel kick plate is made of color steel plate.

[0052] In this embodiment, a control box is installed in the aerial docking device of the suspended platform for high-altitude operations in curtain wall construction. The control box can be installed on the guardrail or in other locations. The control box mainly contains a microcontroller and operational amplifier control circuits.

[0053] The microcontroller and the suspended platform position sensor are electrically connected via wires. The suspended platform position sensor can detect the position status of the suspended platform. When the suspended platform successfully lands on the horizontal support platform, the suspended platform position sensor generates a sensing signal and quickly transmits this signal to the connected microcontroller. After receiving the sensing signal, the microcontroller establishes an electrical connection with the audible and visual alarm through an operational amplifier circuit, controlling the audible and visual alarm to issue an alarm prompt.

[0054] An external power switch is installed on the control box to control the power supply to the entire control box. When construction personnel need to start the control box, they simply turn on the power switch; when the device is not in use or is undergoing maintenance, the power switch is turned off. The control box is also equipped with a battery, which continuously supplies power to the various electronic components inside the control box, ensuring its normal operation.

[0055] In terms of component selection, the STM32F103C8T6 microcontroller can be used. Based on the ARM Cortex-M3 core, it has abundant peripheral resources, such as multiple general-purpose timers, serial communication interfaces, SPI interfaces, etc., which can meet complex control requirements, and it has a fast operating speed and strong processing power.

[0056] Different types of suspended platform position sensors are available. The LJ12A3-4-Z / BX proximity switch sensor is an inductive proximity switch that generates a sensing signal by detecting changes in the distance between a metal object and the sensor. When the suspended platform approaches the horizontal support, the proximity switch sensor can quickly detect the position of the suspended platform, featuring fast response and high reliability.

[0057] like Figure 4 As shown, this embodiment provides a specific form of the operational amplifier control circuit, which specifically includes: resistors R1, R2, R3, and R4, capacitor C1, diodes D1, D2, and D3, transistors Q1 and Q2, and relay J1.

[0058] Resistor R1 limits the current flowing into the base of transistor Q1, preventing damage due to excessive current. Resistors R3 and R2 work together to determine the base voltage of transistor Q2; additionally, they limit current when diode D2 is conducting. Diode D2 can be an LED, providing an illuminating indicator. Capacitor C1 acts as a filter, removing high-frequency interference signals from the power supply, thus ensuring more stable operation of relay J1.

[0059] Diode D1 protects transistor Q1. When transistor Q1 is cut off, it prevents damage from the back electromotive force generated by inductive loads such as relay J1. Transistor Q1 acts as a signal amplification and control element, controlling its own conduction and cutoff according to the magnitude of the input signal, thereby controlling the operation of subsequent circuits. Transistor Q2 acts as a power amplifier, amplifying the control signal from transistor Q1 to drive relay J1. The normally open contact of relay J1 is connected to the audible and visual alarm.

[0060] When the operational amplifier control circuit receives a signal, the signal is applied to the base of transistor Q1 through resistor R1. When the input signal reaches a certain voltage, transistor Q1 turns on. After the collector voltage of transistor Q1 decreases, if the conduction condition of diode D2 is met, diode D2 turns on. Current flows through resistor R3 to diode D2, causing a voltage drop across resistor R3. This voltage drop across resistor R3 provides a suitable voltage to the base of transistor Q2. When this voltage exceeds the conduction voltage of transistor Q2, transistor Q2 turns on. After transistor Q2 turns on, the power supply powers relay J1 through transistor Q2 and resistor R4, causing relay J1 to energize, thus triggering the audible and visual alarm.

[0061] When the input signal disappears or decreases to a certain level, transistor Q1 is cut off, diode D2 is cut off, transistor Q2 is also cut off, relay J1 is de-energized and released, and the audible and visual alarm stops.
