The operation and maintenance personnel pull the unlocked safety rope back to the hand and climb next time, and the remote unlocking is carried out alternately in sequence.

The high falling prevention device for high altitude operation provided by the invention comprises three operations, namely locking operation, manual unlocking operation and remote unlocking operation.

1. The locking operation steps and principle are as follows:

step 1: the lock tongue 14 is inserted into the lock catch bin 12 by bypassing the object to be fixed;

step 2: the lock button 3 is pressed. The locking button moves inwards, the gear 17 is driven to rotate through the rack on the locking button, and the gear rotates to enable the safety rope fixing handle 6 to move downwards. When the locking button 3 moves inwards, the inclined plane of the head part of the locking button pushes up the unlocking button 2 upwards, the locking spring 20 is in a compressed state, the inclined plane penetrates through the unlocking button to enable the groove of the locking button 3 to be clamped into the unlocking button 2, and the locking spring 20 is restored to a self-owned state.

And 3, connecting the lock pin slideway 21 with the safety rope fixing handle 6, moving downwards along with the safety rope fixing handle in the step 2, and pushing the lock pin 13 out under the action of the inclined plane of the lock pin slideway 21. The thin rod on the reset baffle 18 is inserted into the round hole shaft of the safety rope fixing handle 6, the reset spring 19 is fixed outside the reset baffle 18, the spring is in a free state, the reset baffle 18 is fixed on the U-shaped grab handle, and when the safety rope fixing handle moves downwards, the reset spring 19 is compressed.

And 4, pushing out the lock pin 13 and then inserting the lock pin into a round hole of the lock tongue 14, thereby completing the operation of locking and fixing. After locking, the return spring 19 is in a compressed state, and the unlocking spring 20 is in a self-contained state.

2. The manual unlocking operation steps and principles are as follows:

step 1: the release button 2 is manually pushed upward, so that the release button 2 is moved upward and the unlocking spring 20 is in a compressed state.

Step 2: because the return spring 19 is in a compressed state after locking, after the unlocking button 2 moves upwards, the groove of the locking button 3 is not blocked by the unlocking button 2, the return spring 19 starts to restore to a free state and bounces upwards, and the safety rope fixing handle 6 is pushed to move on line at the moment. The fixed handle 6 of safety rope upwards removes and drives gear 17 and rotate, and gear 17 rotates and drives locking button 3 and outwards removes, and locking button 3 top removes 2 inboards of releasing the lock button.

And 3, step 3: the safety line fixing handle 6 moves upwards, the lock pin slideway 21 connected with the safety line fixing handle moves upwards, the upper inclined surface of the safety line fixing handle moves upwards to press the lock pin 13 inwards, and therefore the lock pin 13 is retracted into the U-shaped grab handle.

And 4, step 4: after the lock pin 13 is retracted, the lock catch 14 is separated from the lock catch bin 12 by pulling the safety rope by hand through the action of external force, thereby completing the unlocking operation.

And 5: when the release button is released, the latch slide 21 returns to the free state, and the release button 2 moves downward to return to the state before locking.

3. The remote unlocking operation steps and principles are as follows:

the device ensures that the controller power button 9 is pressed before use while the controller indicator light 11 is not red. Wherein controller pilot lamp 11 divide into green and red, and controller pilot lamp 11 divide into green and indicate that the intelligent control mode is opened, and controller pilot lamp 11 divide into red and indicate that the intelligent control mode is not opened.

Step 1: after one of the safety ropes is fixed on an object, after an operator climbs for a certain distance, the other safety rope is fixed on the object according to the locking operation, and then the controller unlocking button 10 is pressed.

Step 2: the main control chip on the controller circuit board 16 sends out an unlocking instruction through low-power wireless radio frequency.

And step 3: the first fixed high drop prevention device receives the unlocking instruction, the controller circuit board 16 processes the unlocking instruction, and drives the electronic switch on the circuit board to electrify the electromagnet 5 for 100ms.

And 4, step 4: the electromagnet 5 is designed by adopting a push-pull electromagnet principle, and after being electrified, an electromagnet iron core 5-2 moves upwards under the action of a magnetic field, and an electromagnet spring 5-3 is compressed.

And 5: the iron core of the electromagnet 5 is accelerated to the bottom of the unlocking button 2, and the iron core impacts the bottom of the unlocking button 2 under the action of impact force, so that the bottom of the unlocking button 2 moves upwards.

Step 6: the release button 2 is moved upward and the unlocking spring 20 is in a compressed state.

And 7: because the return spring 19 is in a compressed state after locking, after the unlocking button 2 moves upwards, the groove of the locking button 3 is not blocked by the unlocking button 2, the return spring 19 starts to restore to a free state and bounces upwards, and the safety rope fixing handle 6 is pushed to move on line at the moment. The fixed handle 6 of safety rope upwards removes and drives gear 17 and rotate, and gear 17 rotates and drives locking button 3 and outwards removes, and locking button 3 top removes 2 inboards of releasing the lock button.

And step 8: the electromagnet 5 is electrified for a time pole section (generally between 50 and 200 ms), and after the electromagnet iron core 5-2 finishes impacting, the state before electrification is recovered under the action of the electromagnet spring 5-3. The latch release button 2 is released from the force, and the latch slide 21 returns to the free state, so that the latch release button 2 moves downward to return to the state before locking.

And step 9: the safety line fixing handle 6 is moved upwards, the locking pin slideway 21 connected with the safety line fixing handle is moved upwards, the upper inclined surface of the safety line fixing handle is moved upwards to press the locking pin 13 inwards, and therefore the locking pin 13 is retracted into the U-shaped grab handle 1.

Step 10: after the lock pin 13 is retracted, the lock catch 14 is separated from the lock catch bin 12 by external force through pulling the safety rope by hand, thereby completing the remote unlocking operation.

Compared with the prior art, the novel high-altitude operation high-fall prevention device disclosed by the invention can be used for remotely unlocking through the unlocking buttons on the two safety protection ropes. After pressing the release button on a safety protection rope hasp promptly, the hasp of another safety protection rope can be opened automatically to do not need to go down to remove fixedly when climbing in-process is fixed in turn, the physical demands of the operating personnel climbing in-process that has significantly reduced has practiced thrift the time of climbing. The safety protection rope is simple in operation steps, small, exquisite and portable, has the same weight as the existing safety protection rope, and does not additionally increase the counter weight of operation and maintenance personnel. The invention adopts a mutual exclusion unlocking mode, transmits data through low-power-consumption wireless communication, and adopts components and chips which are low-power-consumption components, thereby ensuring more than 4000 times of unlocking control and meeting the requirement of daily operation. The high-fall prevention device provided by the invention keeps manual unlocking, and can ensure that the fixation is manually released like the currently used safety protection rope under the condition that the battery is not electrified.
