[0067] The embodiment of the present invention is also implemented through the following technical solutions.

[0068] In the embodiment of the present invention, an intercepting member 500 is further included. The intercepting member 500 is arranged inside the elevator body 100 and is located at the rear side of the protective door 200.

Based on the threaded groove 505 on the outer surface of the worm 504 and the worm wheel 50 The inner thread groove 505 transmits motion through the meshing of the thread shape, so that the worm wheel 503 rotates on the outer surface of the worm 504, so that the interception rod 502 fixed on the upper end of the worm wheel 503 can rotate together, and the interception of the interception rod 502 is realized by controlling the motor B501. When the loader enters the construction elevator, the interception rod 502 performs preliminary interception on the loader. Based on the rubber pad 506 at the end of the interception rod 502, the end of the interception rod 502 is abutted against the inner wall of the construction elevator to improve the interception effect of the interception rod 502, and the descending height of the interception rod 502 is reasonably adapted to the loader to ensure that the interception rod 502 can block the front or rear side of the loader.

[0069] In addition, the design content of the falling height of the interception bar 502 is as follows:

[0070] During the design phase, the dimensions of a typical loader are measured, including length, width and height, as well as the center of gravity of the vehicle. These dimensional data are used to calculate and determine the optimal descent height of the interceptor bar 502. The center of gravity of the vehicle is calculated based on the weight distribution of the loader to ensure that the descent height of the interceptor bar 502 can cover the center of gravity of the loader so that the loader can be intercepted in time when it slides backward. Computer-aided design software or finite element analysis tools can be used to simulate the dynamic behavior of the loader in the construction elevator. By simulating the backward sliding process of the loader, the descent height of the interceptor bar 502 is observed and adjusted to ensure that it can effectively intercept the loader. Then, at the actual construction site, an actual loader is used for testing, and the height of the interceptor bar 502 is adjusted until the backward sliding of the loader can be effectively intercepted without causing damage to the loader. A height sensor is installed on the interceptor bar 502 to monitor the descent height of the interceptor bar 502 in real time. The operator adjusts the descent height of the interceptor bar 502 in the construction elevator controller 603 according to the actual size and center of gravity of the loader.

The one-way overrunning clutch is integrated inside the reducer. As a part of the reducer, it ensures that the power of the motor A202 is transmitted through the reducer to achieve the purpose of reducing the speed and increasing the torque.

[0078] According to the weight distribution of the loading truck, the conventional center of gravity position calculation formula is used to calculate its center of gravity position. The center of gravity position is the key area that the resistance member 400 needs to cover.

The position of the resistance member 400 should ensure that it can cover the center of gravity position of the loading truck. When determining the optimal position of the resistance member 400, the impact force between the loading truck and the resistance member 400 also needs to be considered, which can be calculated through dynamics, such as using the momentum theorem.

[0079] In an embodiment of the present invention, the anti-fall interception module 600 includes a loader monitoring unit 601, a construction elevator monitoring unit 602, a construction elevator controller 603, an image monitoring unit 604 and an early warning unit 605;

[0080] The loader monitoring unit 601 is used to monitor the usage status of the loader in the construction elevator;

[0081] The construction elevator monitoring unit 602 is used to monitor the operation status of the construction elevator, including the lifting speed, position, etc.;

[0082] The construction elevator controller 603 is used to control the operation of the construction elevator;

[0083] The image monitoring unit 604 uses camera video to monitor the surrounding environment of the loader and the actions of the operator, providing visual safety monitoring, and uses image recognition technology to analyze potential safety risks in the video stream, such as personnel approaching dangerous areas, improper operations, etc.;

[0084] The early warning unit 605 integrates an audible and visual alarm to issue a warning when a risk of the loader slipping backward is detected.

[0085] In the embodiment of the present invention, the loader monitoring unit 601 includes a position monitoring subunit 6011, a speed monitoring subunit 6012, a tilt monitoring subunit 6013 and a weight monitoring subunit 6014;

[0086] The position monitoring subunit 6011 uses a GPS locator to compare the initial position of the loader after entering the construction elevator, as well as the real-time position, with the preset safety area. The GPS locator is installed on the wheel or the loader;

[0087] The speed monitoring subunit 6012 is used to monitor the moving speed of the loader. The speed sensor is used to detect the real-time speed of the loader. The accelerometer is used to detect the acceleration change to determine whether the loader is decelerating or sliding backward.

[0088] The tilt monitoring subunit 6013 uses a tilt sensor to monitor the tilt angle of the loading vehicle. If the loading vehicle tilts beyond a safe angle, it indicates that there is a risk of sliding backward or rolling over. The tilt angle is compared with a preset safety threshold in real time. Once the threshold is exceeded, an alarm is triggered.

[0089] The weight monitoring subunit 6014 uses a pressure sensor to monitor the load condition of the loader to prevent overloading, which causes the vehicle stability to decrease and increases the risk of rolling back. The real-time weight data is compared with the maximum load limit of the loader and a warning is issued when the limit is exceeded.

[0090] In the embodiment of the present invention, the construction elevator controller 603 includes a receiving subunit 6031, a logic processing subunit 6032 and an execution subunit 6033;

[0091] The receiving subunit 6031 is used to receive the loading vehicle status information sent by the anti-fall interception module 600;

[0092] The logic processing subunit 6032 is used to analyze the received status information and perform logic processing according to a preset safety threshold;

[0093] The execution subunit 6033 controls the operation of the construction elevator, the protective door 200 , the resisting member 400 and the intercepting member 500 according to the instructions of the logic processing subunit 6032 .

[0094] Embodiment 2

[0095] Refer to the attached Fig. 9 As shown, an embodiment of the present invention further provides an interception method of a construction elevator anti-fall buffer interception system, comprising the following steps:

[0096] S1, install an anti-fall interception module 600 inside the construction elevator, including a sensor array and a wireless communicator, and connect it to the construction elevator controller 603, configure a receiving subunit 6031 and a logic processing subunit 6032 on the construction elevator controller 603, and ensure that they can correctly receive and process information from the anti-fall interception module 600;

[0097] S2, push the loader into the construction elevator, and the anti-fall interception module 600 monitors the placement status of the loader in real time, including parameters such as position, inclination, and load. The module sends the monitored loader status information to the construction elevator controller 603;

[0098] S3, after the loader completely enters the construction elevator, the induction plate 405 of the blocking member 400 senses the pressure, and uses the preset operation logic in the construction elevator controller 603 to control the blocking member 400 to rise and block in front of the wheels of the loader. The blocking member 400 uses the data monitored by the sensor to adjust the blocking height in real time according to the situation of the loader, and synchronously controls the protection door 200 to close. The motor A202 and the gear 203 cooperate to push the protection door 200 against the inside of the construction elevator, and the interception rod 502 descends to block the front or rear side of the loader, and is set according to the moving direction of the loader;

[0099] S4, controlling the operation of the construction elevator through the construction elevator controller 603, the construction elevator controller 603 receives the status information of the loading vehicle in real time, performs logical processing according to the preset safety rules, and presets the safety threshold of the loading vehicle status;

[0100] S5. When it is monitored that the status of the loader exceeds the safety threshold, the construction elevator controller 603 immediately takes emergency measures, such as stopping the elevator operation, sounding an alarm, etc., and simultaneously monitors the image information of the loader through the image monitoring unit 604 to check whether it is caused by staff operating errors, and makes adjustments based on the safety threshold data of the loader. For example, if the loader is too heavy and exceeds the load, resulting in the resistance member 400 being unable to withstand the loader, it is necessary to reduce the materials in the loader.
