Abstract
Description
Technical Field
[0001] This utility model belongs to the field of high-altitude operation technology, specifically an alarm device for high-altitude operation suspended platforms. Background Technology
[0002] In construction engineering, suspended platforms for high-altitude operations are generally used as work platforms for exterior facade construction. Therefore, their safety requirements are high. According to relevant requirements, operations should be stopped when the gust wind speed at the working location of the suspended platform exceeds 8.3 m / s (equivalent to a level 5 wind) or when encountering severe weather such as heavy rain, fog, or snow.
[0003] In the field of safety protection for suspended platforms for high-altitude operations, existing alarm devices mainly rely on a single sensor (such as weight or limit switch) for simple threshold alarms, which cannot comprehensively judge the coupled risks of multiple factors such as tilt, wind speed, and wire rope health. Therefore, we propose an alarm device for suspended platforms for high-altitude operations. Utility Model Content
[0004] To address the problems raised in the background art, this utility model provides the following technical solution: an alarm device for a suspended platform for high-altitude operations, comprising a suspended platform body, the suspended platform body having a suspension bracket connected to a steel wire rope, an alarm being installed on the suspended platform body, a weight sensor being installed at the bottom of the suspended platform body, an angle sensor being installed at the bottom of the suspended platform body, the suspended platform body having a fence, the fence being connected to the suspension bracket, one side of the fence having an entrance for workers, and the other side of the fence having a bracket with an anemometer installed on the bracket, and a control panel being installed on the bracket, the control panel being electrically connected to the alarm, weight sensor, angle sensor, and anemometer.
[0005] Preferably, there are four weight sensors, which are symmetrically distributed at the four corners of the bottom of the suspended platform. The four-corner distribution can calculate the load eccentricity, solving the problem that traditional single-point measurement cannot detect uneven load and preventing the risk of overturning due to uneven load.
[0006] Preferably, the tilt sensor is located at the center of the bottom of the suspended platform body. The center position is least affected by mechanical vibration interference, resulting in more stable data. Combined with the weight sensors at the four corners, the relationship between tilt and off-center loading can be cross-verified.
[0007] Preferably, the alarm is an audible and visual alarm, which has a buzzer and an LED light to enhance the warning effect in high-altitude environments. The LED flashes red and blue, i.e., red indicates an emergency and blue indicates a warning.
[0008] Preferably, the suspension brackets are located on both sides of the suspended platform body, and a safety lock is provided at the connection between the suspension brackets and the wire rope. A limit switch is provided on the side of the safety lock. Integrating the limit switch into the side of the safety lock reduces the mechanical complexity of separate installation and provides double protection.
[0009] Preferably, the control panel has a backup battery module to maintain system operation when the main power is interrupted, solving the problem that traditional devices fail when power is cut off and ensuring the continuous operation of the alarm function.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] During operation, the weight sensor monitors the load values at each support point in real time. The control panel determines overload and off-center load conditions by calculating the total load and load distribution deviation. The tilt sensor, installed at the geometric center of the bottom of the suspended platform, uses a dynamic filtering algorithm to eliminate mechanical vibration interference and accurately measures the X / Y axial tilt angle of the suspended platform. An anemometer mounted on an extended bracket collects ambient wind speed data in real time using ultrasonic wind measurement principles. The bracket height is adjustable to ensure that the measurement is not obstructed by the suspended platform structure. The limit switch located on the side of the safety lock detects the limit position of the suspended platform's travel through the Hall effect. The control panel receives data from all sensors, makes intelligent judgments, and controls alarm and protection actions. By combining data such as weight, tilt angle, wind speed, and limit switches, the overall safety status is determined. For example, if there is a high wind speed and a large tilt angle, even if there is no overload, it is still judged as a high risk. A blue light flashes during a first-level warning, and a red light flashes during a second-level warning, accompanied by a long beeping buzzer. The motor power is automatically cut off, the safety lock is activated, and the wire rope is locked to prevent further movement. This achieves precise monitoring of the load status and balance of the suspended platform, solving the shortcomings of traditional devices that can only detect a single parameter and reducing the accident rate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0017] Depend on Figure 1-2 The present invention includes a suspended basket body 1, which has a suspension bracket 2 connected to a steel wire rope. An alarm 8 is installed on the suspended basket body 1, a weight sensor 3 is installed at the bottom of the suspended basket body 1, and an angle sensor 4 is installed at the bottom of the suspended basket body 1. The suspended basket body 1 has a fence connected to the suspension bracket 2. One side of the fence has an entrance for workers to pass through, and the other side of the fence has a bracket 5. An anemometer 6 is installed on the bracket 5, and a control panel 7 is installed on the bracket 5. The control panel 7 is electrically connected to the alarm 8, the weight sensor 3, the angle sensor 4, and the anemometer 6.
[0018] There are four weight sensors 3, which are symmetrically distributed at the four corners of the bottom of the suspended basket body 1. The distribution at the four corners can calculate the load eccentricity. If the overload on one side is 30%, an alarm will be triggered, which solves the problem that traditional single-point measurement cannot detect the load eccentricity and prevents the risk of overturning due to uneven load.
[0019] The tilt sensor 4 is located at the bottom center of the suspended platform body 1. The center position is least affected by mechanical vibration interference, and the data is more stable. Combined with the four corner weight sensors, the relationship between tilt and off-center load can be cross-verified. For example, emergency braking is required when the tilt angle is >5° and the load on one side is >25%.
[0020] Alarm 8 is an audible and visual alarm. Alarm 8 has a buzzer and an LED light to enhance the warning effect in high-altitude environments. The LED flashes red and blue, that is, red indicates an emergency and blue indicates a warning.
[0021] The suspension bracket 2 is installed on both sides of the suspended platform body 1. A safety lock 9 is installed at the connection between the suspension bracket 2 and the wire rope. A limit switch 10 is installed on the side of the safety lock 9. The limit switch 10 is integrated into the side of the safety lock 9 to reduce the mechanical complexity of separate installation and provide double protection.
[0022] Control panel 7 has a backup battery module to maintain system operation when the main power is interrupted, solving the problem of traditional devices failing when power is lost and ensuring continuous alarm function.
[0023] Working principle: During operation, the weight sensor 3 monitors the load values at each support point in real time. The control panel 7 determines overload and off-center load conditions by calculating the total load and load distribution deviation. The tilt sensor 4, installed at the geometric center of the bottom of the suspended platform, uses a dynamic filtering algorithm to eliminate mechanical vibration interference and accurately measures the X / Y axial tilt angle of the suspended platform. The anemometer 6, installed through the extended bracket 5, uses ultrasonic wind measurement to collect ambient wind speed data in real time. The bracket height is adjustable to ensure that the measurement is not obstructed by the suspended platform structure. The limit switch 10, located on the side of the safety lock 9, detects the limit position of the suspended platform's travel through the Hall effect. The control panel 7 receives data from all sensors, makes intelligent judgments, and controls alarm and protection actions. It integrates data such as weight, tilt angle, wind speed, and limit switches to determine the overall safety status. For example, when the wind speed is high and the tilt angle is large, even if there is no overload, it is still judged as a high risk. When the first level warning is a minor danger, the blue light flashes. When the second level warning is a serious danger, the red light flashes and a buzzer sounds continuously. It automatically cuts off the motor power, activates the safety lock, and locks the wire rope to prevent further movement. It realizes precise monitoring of the load status and balance of the suspended platform, solves the defect of traditional devices that can only detect a single parameter, and reduces the accident rate.
