The fixed braces 1 that is provided with of one end of safety rope 2, and the other end penetrates from installation pipe 5 and links to each other with stopper 13 is fixed.

The working process of the embodiment: before using, a worker wears the harness 1 on the body firstly, because the worker needs to hang the hook 3 of the safety rope 2 at a position higher than the top of the head of a human body before working, if the loop is not powered off or the grounding wire is not hung well to cause excess pressure on a power failure line, when the worker hangs the safety rope 2 at the hanging point 3 after reaching the working position, the coil on the solenoid 7 in the buffer device generates induction current after being close to an electric field around the lead, the induction current enters the controller 15 from the coil, the controller 15 controls the indicator lamp 20 to flash after receiving a current signal fed back by the coil of the solenoid 7, the buzzer 21 rings to prompt the worker that the loop is not powered off or has excess pressure, the worker stably hangs the hook 3 by sliding down the safety buckle 18 after dealing with the problem of the excess pressure of the loop, and then slides up the safety buckle 18, the safety buckle 18 is used for locking the opening position of the hook 3, the hook 3 is prevented from loosening and falling off due to shaking of workers in the using process, when the worker carelessly falls in the working process after the hook 3 is hung, firstly the safety rope 2 can drag the limiting block 13 to slide in the mounting pipe 5, the first sliding block 17 on the limiting block 13 can simultaneously slide in the sliding groove 6, the limiting spring 9 is firstly stretched in the sliding process of the limiting block 13, the first sliding block 17 can slide to be in contact with the second sliding block 19 after the limiting spring 9 is stretched, then the second sliding block 19 can be pushed to move, the connected support 10 can be driven to slide downwards along the mounting pipe 5 when the second sliding block 19, the guide wheel 11 can move in the solenoid 7 through the steel cable 12 when the support 10 slides, and when the buffer magnet 8 moves, the solenoid 7 does not move due to dragging, therefore, the wire wound on the solenoid 7 cuts the magnetic field around the buffer magnet 8, so as to generate a current in the side coil in the solenoid 7, and when the current is generated in the coil of the solenoid 7, a magnetic field is generated in the solenoid 7, the magnetic field generated by the solenoid 7 can block the movement of the buffer magnet 8 in the solenoid 7, so as to offset the impact force transmitted by the safety rope 2 to the stopper 13, thereby reducing the instant impact force on the safety rope 2, preventing the safety rope 2 from being broken due to the instant impact, preventing the injury to the body of a worker due to an excessive impact force, and transmitting the current generated by the solenoid 7 to the connected controller 15, wherein the controller 15 uses a single chip microcomputer as a control core to perform signal processing and output control, as an example, the single chip microcomputer may be of the type STM32F103ZGT6, and the controller 15 is activated after receiving a current signal transmitted by the solenoid 7, the electric energy provided by the storage battery 16 sends rescue signals to the surroundings, and simultaneously the buzzer 21 rings, the indicator light 20 flickers to warn nearby workers, so that the falling workers can be rescued quickly.

It should be noted that after the bracket 10 completely pulls the buffer magnet 8 from one end of the solenoid 7 to the other end through the steel cable 12, it indicates that the buffer device has reached the limit state, at this time, the second slider 19 on the bracket 10 will slide to the limit position of the sliding slot 6 and be held by the sliding slot 6, and the first slider 17 on the stopper 13 will be held by the second slider 19, so as to prevent the stopper 13 and the safety rope 2 thereof from sliding out of the installation pipe 5 to cause an accident.

The working states of the indicator light and the buzzer described in the embodiment include two conditions, the first condition is that the indicator light flickers and the buzzer rings when the safety belt practical personnel do not fall, and the condition is that a warning is sent to a safety belt user again to indicate that residual pressure still exists in a working area or a loop is not powered off; the second situation is when the safety belt user appears falling, because the safety belt user can be hung in half empty by the safety belt this moment, hardly saves oneself, and the staff in order to indicate around rescues when pilot lamp scintillation and bee calling organ ring this moment.

Finally, the above embodiments are only used 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 to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the scope of the claims of the present invention.
