8. The overhead working harness intelligent hook according to claim 1, wherein: the intelligent hook also comprises a shell and protective silica gel arranged on the surface of the shell.
9. A method for using the intelligent hook of the high-altitude operation safety belt according to any one of claims 7 to 8, which is characterized by comprising a locking method and an unlocking method of the intelligent hook; the locking method of the intelligent hook comprises the following steps:
s1: the safety belt lock head is taken by the safety belt to bypass the position needing to be fixed, including angle steel of an electric power iron tower and a safety bracket for building construction, and the safety belt lock head is inserted into the intelligent hook;
s2: moving the safety belt lock head inwards in the inner main body frame, and pushing the pull pin to move downwards by the end part of the safety belt lock head, so as to compress the pull pin spring when the pull pin moves downwards;
s3: the safety belt lock head continues to move inwards, the end part of the safety belt lock head moves through the pull pin and then pushes the sliding block to move, and the sliding block moves to compress the sliding block spring;
s4: after the limiting hole of the safety belt lock head moves to the position of the pull pin, the pull pin spring is restored to a free state, so that the pull pin returns to a position, and the intelligent hook is locked after the pull pin passes through the limiting hole on the safety belt lock head;
s5: after the intelligent hook is locked, the slider spring is in a compressed state, and meanwhile, the slider triggers the mechanical limit switch, and a processor on the circuit board judges that the intelligent hook is in a locked state.
10. The method of use of claim 9, wherein the method of unlocking the intelligent hook comprises the steps of:
t1: pairing a pair of intelligent hooks through a wireless communication module of the circuit board to realize wireless data transmission of the two intelligent hooks; after the intelligent hook is fixed by an operator, triggering remote unlocking by pressing an unlocking key on one side of the intelligent hook;
t2: after receiving a trigger signal of an unlocking key, the circuit board firstly detects the locking state of the intelligent hook, and if the intelligent hook is in a normal locking state, an unlocking instruction is sent to the other intelligent hook through the wireless module;
t3: after the other intelligent hook receives an unlocking instruction, the circuit board supplies power to the motor through the electric energy in the lithium battery by the driving circuit, and meanwhile, the motor is driven to rotate;
t4: the motor drives the eccentric wheel to rotate, the photoelectric limit switch at one side of the eccentric wheel judges whether the eccentric wheel rotates for one circle, and after the rotation is completed for one circle, the photoelectric limit switch triggers a processor on the circuit board to stop the motor from rotating, and one end of the eccentric wheel with a long radius pushes the movable plate and the pull pin to move outwards in the rotating process;
t5: the pull pin moves outwards to compress the pull pin spring, the upper end of the pull pin is separated from a limiting hole on the safety belt lock head, and the safety belt lock head moves outwards under the pushing of the slide block spring, so that the safety belt lock head is pushed out of the intelligent hook;
t6: when the intelligent hook has low electric quantity and abnormal communication or needs manual unlocking, an operator who manually unlocks the intelligent hook pulls the mechanical pull ring to move outwards, so that the pull pin is driven to move outwards, and the pull pin moves outwards to compress the pull pin spring; one end of the pull pin is separated from a limiting hole on the safety belt lock head, and the safety belt lock head outwards moves under the pushing of the sliding block spring, so that the safety belt lock head is pushed out of the intelligent hook.
