it should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
The working principle is as follows: when the device is used, the leg cover 102a and the waist belt 101 are respectively installed at the required positions, and the latch 107 is pressed into the groove 108a inside the cartridge 108 (installation is completed), and at this time, the latch 107 and the horizontal plate 106b are simultaneously moved downward.
When the fixture block 107 moves downwards, firstly, the end of the fixture block 107 is chamfered, at this time, the fixture block 107 pushes the push plate 301 to start moving outwards, the roller 301b arranged on the surface of the push plate at this time rolls at the bottom of the groove 108a, and the distance between the push plates 301 at this time starts increasing along with the outward movement of the push plate 301, so that the extrusion spring 303 at this time starts to compress, until the protrusion 301a on the surface of the push plate 301 moves to the surface of the connecting post 106a, at this time, the protrusion 301a is reset through the extrusion spring 303, and the fixing effect on the fixture block 107 is completed.
And when the horizontal plate 106b moves downwards, the horizontal plate 106b drives the second slider 213 to slide downwards along the sliding groove 213a, the first slider 211 at this time is pushed to move outwards by the second connecting rod 212, the boss 206 at this time is pushed to move by the first connecting rod 210, the boss 206 moves along the guide rail 206b at this time, the driven rack 209a connected by the second limiting rod 206a moves at this time, the surface of the driven rack 209a is also meshed with the driving gear 209, but the positioning rod 209b connected by the driven rack 209a is inserted into the protrusion 301 (the initial positioning rod 209b is not inside the protrusion 301 a), and the positioning rod 209b is always located outside the protrusion 301 due to the arrangement of the return spring 204, and the return spring 204 is not influenced by external force, and moves automatically after the clamping is finished.
When the safety belt needs to be unlocked, the transmission shaft 205 is rotated through the knob 201 at the moment, the worm 207 connected to the tail end of the transmission shaft 205 starts to move, the worm 207 is provided with the worm wheel 208 in a meshed mode on the surface to rotate, the driving gear 209 is arranged in a coaxial connection mode at the center of the worm wheel 208, the driving gear 209 starts to rotate at the moment, the driven rack 209a arranged on the surface of the driving gear 209 in a meshed mode starts to move towards two sides at the moment, the positioning rod 209b at the moment is further driven to move, the distance between the protrusions 301a at the moment is changed through the positioning rod 209b, the fixture block 107 can be detached at the moment, and the safety belt is convenient to wear.
When the safety belt is used, as the safety belt is provided with the loss acceleration, the laser and the ultrasonic distance measuring equipment, the safety belt is controlled by the embedded CPU. When the system detects that the calculation is more than 2 meters from the starting surface, the use 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 again, and reminding is carried out at intervals of 2 minutes. After the height of the safety belt exceeds 2 meters, the backup safety rope is used for the first time, the system enters transposition monitoring, if the safety belt and the backup safety rope are opened simultaneously in subsequent operation, the system carries out voice prompt and transmits information to a background. And in the rod descending process, the system is closed after the detection distance is less than 1.5 meters. When the operator works over 2 meters, the system detects the acceleration of 0.5 meter/second and keeps the acceleration for over 3 seconds, and sends a signal for starting an emergency plan to the background.
