[0002] With the rapid urbanization in my country, high-rise buildings are becoming increasingly common, and construction elevators play a crucial role in the construction process. However, construction elevators are commonly used for transporting materials between floors on construction sites. To better promote green construction and reduce on-site carbon dioxide emissions, electric vehicles or loaders are typically used to transport materials to the construction elevator, which then transports them to the working floor. However, due to operational errors or system malfunctions, electric vehicles or loaders may roll backward, posing a significant safety risk of falling from heights. To mitigate this risk, effective intervention measures are necessary. Therefore, this paper designs a construction elevator fall prevention buffer interception system and interception method.

[0062] Example 1

[0063] See attached document Figure 1-8 As shown, the present invention provides a technical solution: a construction elevator anti-fall buffer interception system, including an elevator body 100 and a protective door 200. The protective door 200 is disposed inside the door frame 201 of the elevator body 100. The protective door 200 includes a door frame 201, a motor A202 and a gear 203. The motor A202 is disposed at the upper end of the door frame 201, and the gear 203 is disposed at the output end of the motor A202. The upper end of the door frame 201 is provided with a tooth groove 204 that meshes with the gear 203.

[0064] The movable door panel assembly 300 is disposed on the inner side of the door frame 201. The movable door panel assembly 300 includes a double-layer plate 301, a mounting frame 302 and a movable rod 303. The mounting frame 302 is embedded in the inner side of the door frame 201, and the movable rod 303 is disposed between the double-layer plate 301 and the mounting frame 302.

[0065] A stopper 400 is embedded in the inner bottom of the elevator body 100. The stopper 400 includes a fixed frame 401, a top plate 402, a movable hinge 403, a movable plate 404, a sensor plate 405, and a push rod 406. The top plate 402 and the movable plate 404 are both located inside the fixed frame 401. The movable hinge 403 is located between the fixed frame 401 and the lower end of the top plate 402. The movable plate 404 is located at the upper end of the top plate 402. The sensor plate 405 is embedded on the surface of the top plate 402. The push rod 406 is located between the bottom surface of the top plate 402 and the fixed frame 401.

[0066] The anti-fall interception module 600 is used to monitor the placement status of the loading vehicle inside the construction elevator, and wirelessly communicates with the controller of the construction elevator to report the status of the loading vehicle to the controller and control the construction elevator.

[0067] The embodiments of the present invention are also implemented through the following technical solutions.

[0068] In an embodiment of the present invention, an interceptor 500 is also included. The interceptor 500 is disposed inside the elevator body 100 and located behind the protective door 200. The interceptor 500 includes a motor B501 and an interceptor rod 502. The motor B501 is screwed to the inside of the elevator body 100. A worm gear 504 is provided at the output end of the motor B501. A worm wheel 503 is fixed at the bottom end of the interceptor rod 502. A threaded groove 505 adapted to the worm gear 504 is opened on the inner side of the worm wheel 503. A pad 506 made of rubber is fixed at the upper end of the interceptor rod 502. The worm gear 504 is rotated by controlling the worm gear 504 using the motor B501. Based on the threaded groove 505 on the outer surface of the worm gear 504 and the worm wheel 504, the interceptor 502 is rotated. The inner threaded groove 505 transmits motion through the meshing of the thread shape, enabling the worm gear 503 to rotate on the outer surface of the worm 504. This allows the intercepting rod 502, fixed at the upper end of the worm gear 503, to rotate along with it. The intercepting rod 502 is controlled by the motor B501 to achieve interception. When the loading vehicle enters the construction elevator, the intercepting rod 502 performs initial interception work on the loading vehicle. Based on the rubber pad 506 at the end of the intercepting rod 502, the end of the intercepting rod 502 abuts against the inner wall of the construction elevator, improving the interception effect of the intercepting rod 502. Furthermore, the descent height of the intercepting rod 502 is reasonably adapted to the loading vehicle to ensure that the intercepting rod 502 can block the front or rear of the loading vehicle.

[0069] In addition, the design details of the descent height of the interceptor bar 502 are as follows:

[0070] During the design phase, the dimensions of a typical loader are measured, including length, width, and height, as well as the vehicle's center of gravity. These dimensional data are used to calculate and determine the optimal lowering height of the interceptor bar 502. Based on the loader's weight distribution, the vehicle's center of gravity is calculated to ensure that the lowering height of the interceptor bar 502 covers the loader's center of gravity, enabling timely interception in case of backward slippage. Computer-aided design software or finite element analysis tools can be used to simulate the dynamic behavior of the loader within the construction elevator. By simulating the backward slippage process, the lowering height of the interceptor bar 502 is observed and adjusted to ensure its effective interception. Then, at the actual construction site, actual loader is used for testing, and the height of the interceptor bar 502 is adjusted until it effectively intercepts backward slippage without damaging the loader. A height sensor is installed on the interceptor bar 502 to monitor its lowering height in real time. Operators adjust the lowering height of the interceptor bar 502 within the construction elevator controller 603 according to the actual dimensions and center of gravity of the loader.

[0071] In an embodiment of the present invention, the upper end of motor A202 is screwed to the door frame 201 of elevator body 100, and the output end of motor A202 is driven by gear 203. A guide wheel 205 is provided at the bottom end of door frame 201, and a guide strip 206 is slidably connected to the guide wheel 205 below it. The guide strip 206 is screwed to the inner bottom surface of the construction elevator. Motor A202 is installed on door frame 201 of elevator body 100 using screws. Motor A202 controls gear 203 to rotate, and gear 203 pushes door frame 201 with toothed grooves 204 to move horizontally to close. Motor A202 is a bidirectional rotating motor. With the control logic of construction elevator controller 603 and reducer with one-way overrunning clutch, reverse rotation of gear 203 is effectively prevented from both control and structural aspects. This design ensures that one side of the door frame 201 is pressed against the inside of the construction elevator, preventing the impact of the loading vehicle shifting or sliding backward from knocking the door frame 201 open. The one-way overrunning clutch is integrated inside the reducer, serving as part of the reducer to ensure that the power of the motor A202 is transmitted through the reducer, achieving the purpose of reducing speed and increasing torque. The reducer is installed between the gear 203 and the output end of the motor A202. While the door frame 201 moves, the bottom guide wheel 205 moves above the guide bar 206, maintaining the horizontal movement of the door frame 201. A movable groove is provided on the outside of the door frame 201 of the elevator body 100. When the protective door 200 is open, the door frame 201 is positioned outside the construction elevator through the movable groove, and the outer surface of the guide bar 206 is equipped with a rubber pad, thus not affecting the loading vehicle's entry into the construction elevator.

[0072] In an embodiment of the present invention, two movable door panel assemblies 300 are provided on the inner side of the door frame 201. The mounting frame 302 is screwed to the door frame 201. The movable rod 303 has a T-shaped cross-section and is rotatably connected to the mounting frame 302. A connecting bolt 304 is provided between the movable rod 303 and the double-layer plate 301, and the two are connected by the connecting bolt 304. A pin is provided to fix the other side of the double-layer plate 301 to the door frame 201. One end of the movable rod 303 is installed on one of the door panels 3011 of the double-layer plate 301 by the connecting bolt 304. Based on the shape of the movable rod 303, the other end rotates inside the mounting frame 302 by the thread and is fixed in position by the screw, so that the double-layer plate 301 can move inside the door frame 201 and is closed by the screw and the pin when it needs to be closed.

[0073] In an embodiment of the present invention, the double-layer plate 301 includes two door panels 3011, a damping plate 3012, a spring 3013, and a piston rod 3014. A damping plate 3012 is fixed to the inner side of each of the two door panels 3011. The spring 3013 and the piston rod 3014 are disposed between the two damping plates 3012 and threadedly engaged with the damping plates 3012. The piston rod 3014 is disposed inside the spring 3013. The spring 3013 includes a small-diameter spring 3013 and a large-diameter spring 3013. Spring 3013 is placed inside the small-diameter spring 3013. Piston rod 3014 is either a pneumatic piston rod 3014 or a hydraulic piston rod 3014. Depending on the selected piston rod 3014, it is equipped with matching components such as a cylinder or a hydraulic cylinder. The door panel 3011 located on the front side is used as a buffer plate. When the loading vehicle in the construction elevator slides backward, the spring 3013 and piston rod 3014 work together to buffer the impact of the loading vehicle and reduce the risk of the door panel 3011 being knocked off.

[0074] In an embodiment of the present invention, at least four abutment members 400 are provided on the inner bottom surface of the elevator body 100, corresponding to the four wheels of the loading vehicle. The abutment members 400 are designed with a modular structure to allow customization according to the size and weight of different loading vehicles. The position of the abutment members 400 can be automatically adjusted according to the position and weight of the loading vehicle. The mounting frame 302 is screwed to the elevator body 100. The mounting frame 302 has a hollow design to facilitate the movement of the top plate 402 and the movable plate 404. The upper ends of the top plate 402 and the movable plate 404 are welded together. The movable plate 404 has an arc-shaped design to facilitate lifting and lowering. The movable plate 404 is movably connected to the mounting frame 302. A push rod 406 is provided between the push rod 406 and the top plate 402. A connecting block 407 is located at the upper end of the sensing plate 405 and is offset from the sensing plate 405. The upper end of the push rod 406 is provided with a connector 408 that is screwed to the connecting block 407. The push rod 406 is either a motor push rod 406 or an electromagnetic push rod 406. At least two push rods 406 are provided inside the mounting frame 302. One push rod 406 is connected to the top plate 402, and the other is connected to the movable plate 404, so that the top plate 402 and the movable plate 404 can support the force brought by the backward movement of the loading vehicle and resist the wheels of the loading vehicle. Sensors are provided inside the sensing plate 405, including pressure sensors, displacement sensors, etc., to monitor the pressure, displacement, position and other information of the loading vehicle.

[0075] In addition, the detailed steps for the automatic adjustment of the position of the stopper 400 are as follows:

[0076] A GPS locator is installed on the loader to monitor its position in real time. A pressure sensor is installed on the sensing plate 405 of the stopper 400 to monitor the weight of the loader and transmit the real-time data to the construction elevator controller 603. The construction elevator controller 603 receives the sensor data and calculates the optimal position of the stopper 400 based on the position and weight of the loader. According to the instructions of the control unit, the push rod 406 is controlled to adjust the position of the stopper 400. The sensor continuously monitors the position and weight of the loader and adjusts the stopper 400 in real time.

[0077] The optimal position of the stopper 400 is calculated as follows:

[0078] Based on the weight distribution of the loader, the center of gravity position is calculated using a conventional formula. The center of gravity position is the key area that the blocking component 400 needs to cover. Based on the center of gravity position of the loader, the area that the blocking component 400 needs to cover is determined. The position of the blocking component 400 should ensure that it can cover the center of gravity position of the loader. When determining the optimal position of the blocking component 400, the impact force between the loader and the blocking component 400 also needs to be considered. This force can be obtained through dynamic calculations, such as using the momentum theorem.

[0079] In an embodiment of the present invention, the fall prevention interception module 600 includes a loading vehicle 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 operating status of the construction elevator, including 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 loading vehicle and the actions of the operators, providing visual safety monitoring. It uses image recognition technology to analyze potential safety risks in the video stream, such as personnel approaching dangerous areas or improper operation.

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

[0085] In an embodiment of the present invention, the loading vehicle 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 location monitoring subunit 6011 uses a GPS locator to compare the initial position and real-time position of the loading vehicle after it enters the construction elevator with the preset safety zone. The GPS locator is installed on the wheels or on the loading vehicle.

[0087] The speed monitoring subunit 6012 is used to monitor the moving speed of the loading vehicle. It uses a speed sensor to detect the real-time speed of the loading vehicle and an accelerometer to detect changes in acceleration, in order to determine whether the loading vehicle is decelerating or rolling backward.

[0088] The tilt monitoring subunit 6013 uses a tilt sensor to monitor the tilt angle of the loader. If the loader tilts beyond the safe angle, it indicates a risk of rolling backward or overturning. 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 of the loader to prevent overloading. Overloading reduces vehicle stability and increases the risk of rolling backward. It compares the real-time weight data with the maximum load limit of the loader and issues a warning when the limit is exceeded.

[0090] In an 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 the preset security threshold.

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

[0094] Example 2

[0095] See attached document Figure 9 As shown in the figure, another embodiment of the present invention provides an interception method for a construction elevator fall prevention buffer interception system, which includes the following steps:

[0096] S1, Install a fall prevention 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 to ensure that they can correctly receive and process information from the fall prevention interception module 600.

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

[0098] S3, after the loader has fully entered the construction elevator, the sensor plate 405 of the stop 400 senses the pressure and uses the preset operation logic in the construction elevator controller 603 to control the stop 400 to rise and stop in front of the loader's wheels. The stop 400 uses the data monitored by the sensor to adjust the height of the stop in real time according to the situation of the loader, and simultaneously controls the protective door 200 to close. The motor A202 and gear 203 work together to push the protective door 200 against the inside of the construction elevator, and the intercepting bar 502 descends to stop in front of or behind the loader, depending on the direction of movement of the loader.

[0099] S4, the operation of the construction elevator is controlled by 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 the status of the loading vehicle is detected to exceed the safety threshold, the construction elevator controller 603 immediately takes emergency measures, such as stopping the elevator operation and issuing an alarm. At the same time, the image monitoring unit 604 monitors the image information of the loading vehicle to check whether it is caused by the operator's operation error. Adjustments are made according to the safety threshold data of the loading vehicle. For example, if the loading vehicle is too heavy and exceeds the load, causing the blocking part 400 to be unable to stop the loading vehicle, it is necessary to reduce the material in the loading vehicle.
