Description

Technical Field

[0001] The present invention relates to the technical field of high-altitude fall prevention evaluation, and in particular to a safety protection evaluation method and system based on a high-altitude fall prevention device. Background Art

[0002] At present, in high-altitude operations in many industries such as power laying and construction, a reliable fall prevention system is usually set up to ensure the safety of workers in high-altitude operations. Therefore, it is necessary to ensure the safety protection performance of the fall prevention system.

[0003] The existing fall arrest system usually includes steel wire rope or braided rope, pulley, brake and safety belt. The fall arrester is fixedly installed on the building or structure. When the worker falls, the braided rope or steel wire rope is pressed against the gear on the fall arrester to increase the anti-fall friction force, thereby realizing rapid braking of the fall arrester and preventing the worker from continuing to fall. However, in actual use, workers often simply check whether the appearance of the fall arrester is damaged or manually pull the steel wire rope and the fall arrester a few times to see if the brake can be applied, and then use it directly. The instantaneous pulling force generated when the worker actually falls is much greater than the braking force detected by a simple test before the operation. The simple test results are difficult to prevent the actual fall. There is room for further optimization of the actual safety protection detection of high-altitude fall arrest devices.

[0056] The present application is further described in detail below in conjunction with the accompanying drawings.

[0057] In one embodiment, if Figure 1 As shown, the present application discloses a safety protection evaluation method based on a high-altitude fall prevention device, which specifically includes the following steps:

[0058] S10: Obtain the personnel weight and construction height of each high-altitude operation, set the evaluation simulation weight of the high-altitude fall prevention device to the current personnel weight to perform a fall simulation, and obtain a simulated braking distance corresponding to the current personnel weight.

[0059] Specifically, before performing high-altitude operations, the operators manually input data such as the operator's weight and construction height, and set the evaluation simulation weight of the high-altitude fall protection device to the current weight of the operator to perform a fall simulation. The length of the safety rope when the operator reaches a stationary state after falling is used to obtain the simulated braking distance corresponding to the current weight of the operator.

[0063] S102: Evaluate the remaining service life of the high-altitude fall prevention device based on the wear attenuation coefficient, and when the remaining service life reaches a preset replacement value, promptly replace the high-altitude fall prevention device that has reached the preset service life.

[0064] Specifically, the remaining service life of the high-altitude fall prevention device, that is, the effective remaining number of fall prevention times, is evaluated based on the wear attenuation coefficient. When the wear attenuation coefficient reaches a preset attenuation value, it means that the remaining service life has reached a preset replacement value. The high-altitude fall prevention device that has reached the preset service life should be replaced in a timely manner.

[0065] S20: comparing the simulated braking distance with the initial braking distance of the high-altitude fall prevention device, analyzing the wear of the braking components of the high-altitude fall prevention device according to the braking comparison result, and obtaining wear analysis data.

[0066] Specifically, Figure 3 As shown, step S20 includes:

[0067] S201: Calculate the braking distance difference between the simulated braking distance and the initial braking distance of the high-altitude fall prevention device, compare the braking distance difference with a preset safe braking distance, and obtain a safe braking comparison result.

[0068] Specifically, the braking distance difference is obtained by subtracting the initial braking distance from the simulated braking distance, and the braking distance difference is compared with the preset safe braking distance, that is, the difference between the braking distance difference and the preset safe braking distance is calculated as the safe braking comparison result.

[0069] S202: When the safety braking comparison result exceeds a preset safety threshold, infrared scanning is performed on the high-altitude anti-fall device to obtain an internal infrared image of the high-altitude anti-fall device.

[0070] Specifically, when the safety braking comparison difference exceeds a preset safety threshold, an infrared scan is performed on the high-altitude anti-fall device through a preset infrared probe to obtain an internal infrared image of the high-altitude anti-fall device.

[0072] Specifically, a comparison is performed between the internal infrared image and the initial infrared image of the high-altitude fall prevention device, and positions where there are differences in infrared spectrum values ​​are marked. The wear conditions of the brake components of the high-altitude fall prevention device are obtained based on the positions of the marked image points, such as the specific positions of the brakes, and the wear analysis data of the high-altitude fall prevention device are obtained.

[0073] S30: Analyze the optimal buffer length of the protective rope of the high-altitude fall protection device based on the wear analysis data, and calculate the instantaneous braking acceleration during the fall based on the optimal buffer length and the test simulation weight.

The wear sliding distance in this embodiment is equal to the difference between the simulated braking distance under the current wear state and the last simulated braking distance.

[0077] S302: Calculate the length of the protective rope of the high-altitude fall prevention device according to the operation requirements, superimpose the wear and sliding distance with the length of the protective rope, and obtain the optimal buffer length of the protective rope that meets the current operation requirements.

[0078] Specifically, the protection distance requirement for the corresponding working height is calculated according to the different requirements of high-altitude operations, and then the corresponding protection rope length is set according to the protection distance requirement. The wear and sliding distance is superimposed on the protection rope length to obtain the optimal buffer length of the protection rope that meets the current working requirements.

[0079] S303: According to the optimal buffer length and the test simulation weight, the instantaneous braking acceleration during the fall is calculated by formula (3), and formula (3) is as follows:

[0081] Among them, a 瞬 Indicates the instantaneous braking acceleration when falling, S 佳 Indicates the optimal buffer length of the protective rope, t 坠 Indicates the fall time corresponding to the optimal buffer length, F 坠 It represents the force exerted by the test simulation weight in free fall within the optimal buffer length, and m represents the test simulation weight corresponding to the weight of the person.

[0082] S40: Analyze the protective safety performance of the high-altitude fall prevention device in the current wear state at the current construction height according to the instantaneous braking acceleration, and obtain safety protection evaluation data that matches the high-altitude fall prevention device with the current high-altitude operation.

[0083] Specifically, step S40 includes:

[0088]

[0089] Among them, H 施 Indicates the current construction height, h 楼 Indicates the floor height of the current construction building, n indicates the number of floors below the current construction location, S 安 Indicates the safe distance for falling.

[0090] S403: Perform distance comparison processing on the instant braking distance and the fall safety distance, analyze the protection safety performance at the current construction height according to the distance comparison result, and obtain safety protection evaluation data matching the current high-altitude operation.

[0091] Specifically, a distance comparison process is performed between the instantaneous braking distance and the fall safety distance, such as calculating the difference between the instantaneous braking distance and the fall safety distance, and analyzing the safety protection performance at the current construction height based on the calculated difference. For example, when the instantaneous braking distance is less than the fall safety distance, the current safety protection performance is better; when the instantaneous braking distance is close to the fall safety distance, the current safety protection performance is worse, thereby obtaining safety protection evaluation data that matches the current high-altitude operation.
