Personal safety appliance for preventing falling in whole process of climbing pole for line repair

Abstract

The invention discloses a personal safety appliance for preventing falling in the whole process of climbing a pole for line repair. The personal safety appliance comprises a c-shaped falling prevention hook 2 with a limit function, a c-shaped opening sealing hook 3, a trapezoid spring 1 and a safe rope connecting pile, wherein left baffles 4 are inwards arranged at the front and the back of the left side of the c-shaped falling prevention hook 2 with a limit function; right baffles 5 are inwards arranged at the front and the back of the right side of the c-shaped falling prevention hook 2 with a limit function; the c-shaped opening sealing hook 3 is sleeved in the left and right baffles of the c-shaped falling prevention hook 2 with a limit function; the trapezoid spring 1 is arranged between the upper end of the c-shaped falling prevention hook 2 with a limit function and the top of the c-shaped opening sealing hook 3. According to the personal safety appliance, the opening and closing of the hooks can be realized through spring linkage by using the two superimposed c-shaped hooks, an operator climbing the pole up and down is prevented from falling from the altitude, the occurrence of falling from the pole due to slippery hand grabbing can be effective avoided, the operator is enabled to be always reliably hung on clinch nails, the safety in the climbing process can be ensured, and the personal safety appliance is a personal light-weight low-cost and efficient falling prevention appliance which is developed according to action principles and loading features of a human body in the pole climbing process.
