Description
Technical Field
[0001] The utility model relates to the technical field of anti-falling for aerial work, and in particular to an anti-falling structure for an aerial work platform. Background Art
[0002] When working at height, in order to prevent the high-altitude workers from falling due to the sudden collapse of the high-altitude work platform, safety ropes are generally used to protect the high-altitude workers from falling. However, the safety ropes currently used for fall protection do not have corresponding sensing warning structures, and cannot force high-altitude workers to use safety ropes when working at height. Therefore, when high-altitude workers perform high-altitude work without using safety ropes, sensing warnings cannot be achieved, resulting in high-altitude workers performing high-altitude work without protection, which poses a safety hazard.

After sensing that a person has stepped into the area, the second human infrared sensor is used to achieve cooperative sensing to sense whether the current person is wearing a full-body safety strap. In addition, the present application uses a high-decibel buzzer warning. When it is detected that the current person is not wearing a full-body safety strapper, a long-term high-decibel buzzer warning is achieved through the buzzer, thereby forcing the current person to wear a full-body safety strapper before performing high-altitude work, so as to ensure the safety of their high-altitude construction and ensure that the present application can play a corresponding high-altitude fall prevention role.

Setting: the front end surface of the anti-fall matching block 1 is welded with two limiting support blocks 103 with a rectangular bar structure in a left-right symmetrical shape, and the front end surfaces of the two limiting support blocks 103 are jointly welded with a baffle 104 with a rectangular plate structure. The setting of the baffle 104 can prevent the slider 202 from sliding out of the limiting support block 103; the rear end of the full-body safety strap 2 is fixedly connected with two connecting belts 201 in a left-right symmetrical shape, and the tops of the two connecting belts 201 are fixedly installed with a slider 202 with a rectangular frame structure, and the two sliders 202 are respectively slidably plugged into the two limiting support blocks 103; the top surface of the anti-fall matching block 1 is fixedly installed with a bottom mounting plate 105 by bolts, and a top mounting plate 107 with a mounting hole is provided directly above the bottom mounting plate 105, and the bottom end surface of the top mounting plate 107 and the top surface of the bottom mounting plate 105 are welded together by two connecting plates 106 that are symmetrically distributed on the left and right.
[0024] In this embodiment, a buzzer 101 and a power switch 102 are installed on the right end face of the anti-fall matching block 1, and the buzzer 101 and the power switch 102 are electrically connected to the microcontroller 1012; a timing module 1010 is also provided inside the anti-fall matching block 1, and the timing value of the timing module 1010 is five seconds; when the first human infrared sensor 109 senses a human infrared signal, the first human infrared sensor 109 feedback signal is given to the microcontroller 1012, and the microcontroller 1012 controls the timing module 1010 and the second human infrared sensor 203 to start; when the timing value of the timing module 1010 is reached, the timing module 1010 feedback signal is given to the microcontroller 1012, and the microcontroller 1012 controls the buzzer 101 to start; when the second human infrared sensor 203 senses a human infrared signal, the second human infrared sensor 203 feedback signal is given to the microcontroller 1012, and the microcontroller 1012 controls the buzzer 101 to turn off.
[0025] The working principle of this embodiment is as follows:
[0026] Screws and other fasteners are inserted through the mounting holes on the top mounting plate 107 and fixedly connected to the top surface of the building to achieve high-altitude fixed installation of the anti-fall matching block 1. The sensing matching groove 108 is facing the aerial work platform, and the limit support bar 103 is located above the aerial work platform.
[0027] Press the power switch 102 to start the application. When the aerial worker enters the aerial work platform area, the first human infrared sensor 109 will sense the infrared signal of the aerial worker. The first human infrared sensor 109 will give a feedback signal to the microcontroller 1012. The microcontroller 1012 controls the timing module 1010 and the second human infrared sensor 203 to start. If the aerial worker who enters the aerial work platform area is not wearing the full-body safety harness 2, when the five-second timing value of the timing module 1010 is reached, the timing module 1010 will give a feedback signal. The signal is given to the microcontroller 1012, which controls the buzzer 101 to start, and the high-decibel buzzer 101 is used to warn the current high-altitude worker. When the high-altitude worker wears the full-body safety harness 2, the second human infrared sensor 203 fixedly installed on the rear side of the inner end of the full-body safety harness 2 will sense the infrared signal of the high-altitude worker. The second human infrared sensor 203 will give a feedback signal to the microcontroller 1012, and the microcontroller 1012 will control the buzzer 101 to turn off, so as to stop the high-decibel buzzer warning.
[0028] When a high-altitude worker walks around the aerial work platform area wearing the full-body safety harness 2, the connecting belt 201 will drive the slider 202 to move back and forth along the limit support strip 103, thereby ensuring that it will not cause any obstruction to the high-altitude worker's aerial work. When the aerial work platform tilts or falls due to loose installation, the mutual connection and support between the full-body safety harness 2, the connecting belt 201, the slider 202 and the limit support strip 103 can prevent the high-altitude worker from falling and ensure his life safety.
