Controller of novel human body backup protection rope

Abstract

The invention discloses a controller of a novel human body backup protection rope. The controller comprises a supporting frame, a fixed pulley, a movable pulley and a hook, wherein the supporting frame is formed by locking two side baffles and two screw rods through nuts; the fixed pulley can freely slide in a waist-shaped slide groove in the middle of the supporting frame; two springs are arranged on two sides of the supporting frame; one end of each spring is connected to the screw rod on which the hook is arranged, and the other end of the spring is connected to the movable pulley. By using the controller of the human body backup protection rope, a twisting phenomenon of the protection rope and the controller can be well avoided; moreover, when emergent high-altitude falling occurs, the springs are pulled apart by the protection rope to drag the movable pulley to get close to the fixed pulley, and due to extrusion between the pulleys and friction of the protection rope, a braking effect is achieved, so that psychological burden of working personnel is reduced, manpower and material resources are reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a protection device, in particular to a novel personal backup protection rope controller. Background technique [0002] In the transmission network operation, when the electrician uses the ladder to enter the electric field, in order to prevent falling from high altitude during the process of climbing the ladder and getting off the ladder, we will set up a personal backup protection rope on the person. At present, we use a U-shaped The ring is used as a fulcrum on the ground. When workers working at heights are working, many people on the ground pull the backup protection rope through the U-shaped ring. This method is time-consuming and laborious, and there is no emergency braking function. When the U-shaped ring is in use, there is no guidance for the rope, so the phenomenon that the rope rotates left and right on the U-shaped ring often appears, which reduces the safety. work efficiency. Contents of the invention [0003]...
