Working principle: in use, the device is first installed with the leg cuffs 102a and the waist belt 101 in the desired positions, respectively, and the latch 107 is pressed into the recess 108a in the cartridge 108 (complete installation), and at this time the latch 107 and the cross plate 106b are simultaneously moved downward.
When the clamping block 107 moves downwards, firstly, the end of the clamping block 107 is subjected to chamfering treatment, at this time, the clamping block 107 pushes the push plate 301 at this time to start to move outwards, the roller 301b arranged on the surface at this time rolls on the bottom of the groove 108a, and along with the outward movement of the push plate 301, the distance between the push plates 301 at this time starts to become larger, and the compression spring 303 at this time is brought to start to compress until the protrusion 301a on the surface of the push plate 301 moves to the surface of the connecting column 106a at this time, the protrusion 301a is reset through the compression spring 303, and the fixing action on the clamping block 107 is completed.
And when the cross plate 106b moves downwards, the cross plate 106b drives the second slider 213 to slide downwards along the chute 213a, finally, the first slider 211 is pushed by the second connecting rod 212 to start moving outwards, and finally, the boss 206 is pushed by the first connecting rod 210 to move, and the boss 206 moves along the guide rail 206b, and the driven rack 209a connected by the second limiting rod 206a moves, and the surface of the driven rack 209a is meshed with the driving gear 209, but the positioning rod 209b connected with the driven rack 209a is inserted into the boss 301 (the initial position positioning rod 209b is not in the boss 301 a), and due to the reset spring 204, the reset spring 204 is not influenced by external force, the positioning rod 209b is always located outside the boss 301, and moves automatically after the clamping is completed.
When the safety belt is required to be unlocked, the transmission shaft 205 is rotated through the knob 201 at this moment, the worm 207 connected with the tail end of the transmission shaft 205 starts to move, the worm 207 surface is meshed with the worm wheel 208 to rotate, the driving gear 209 starts to rotate because the driving gear 209 is coaxially connected with the center position of the worm wheel 208, the driven rack 209a meshed with the surface of the driving gear 209 starts to move to two sides at this moment, the positioning rod 209b at this moment is driven to move, the spacing between the protrusions 301a at this moment is changed by the positioning rod 209b, and the clamping block 107 can be detached at this moment, so that the safety belt is convenient to wear.
In use, the safety belt is provided with the loss acceleration, laser and ultrasonic ranging equipment, and is controlled by the embedded CPU. When the system detects that the calculated distance exceeds 2 meters, the service condition of the safety belt is actively checked, if the safety belt is not closed, a voice prompt is sent out to prompt the height, and violation information is transmitted to the background. When the height reaches 5 meters, detection reminding is carried out once again, and reminding is carried out at intervals of 2 minutes. After the height exceeds 2 meters, the backup safety rope is used for the first time, the system enters the transposition monitoring, and in the subsequent operation, for example, the safety belt and the backup safety rope are simultaneously opened, the system carries out voice prompt and transmits information to the background. In the process of pole setting, the system is closed after the detection distance is smaller than 1.5 meters. When the operator works more than 2 meters, the system detects the acceleration of 0.5 meter/second and keeps the acceleration for more than 3 seconds, and sends a starting emergency plan signal to the background.
