Description

Technical Field

[0001] This utility model relates to the field of insulating tools, specifically an insulating tool with a safety rope. Background Technology

[0002] Insulating tools are a type of safety tool specifically designed for live-line work or electrical maintenance. Their core feature is to block the current path through special materials and structural design, protecting operators from electric shock. Insulating tools with safety ropes are a type of composite safety equipment that has both insulation protection and anti-drop functions. They are mainly used in high-risk scenarios such as power maintenance and communication tower work.

[0003] Existing power maintenance procedures, especially in high-risk electrical contact environments, typically require one worker to operate the equipment while another worker follows behind, using a grab bar extension to secure the operator around their waist. This allows for quick repositioning and disconnection from the power source in case of emergencies, improving worker safety. However, because workers wear heavy insulated clothing, they are prone to slipping the grab bar due to tension, which can delay rescue efforts. Therefore, we provide an insulated tool with a safety rope. Utility Model Content

[0004] The purpose of this invention is to provide an insulating tool with a safety rope to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An insulated tool with a safety rope, comprising: A grab bar assembly, and a safety rope storage assembly disposed inside the grab bar assembly for releasing the safety rope; The gripper assembly includes: A gripping bar, one end of which is fixedly connected to an extension rod for extending the operating distance, and the end of the extension rod away from the gripping bar is fixedly connected to a gripping hook for looping around the waist of the operator; The safety rope storage assembly includes: A safety rope, one end of which is fixedly connected to a fixing strap, and the other end of which is internally fitted with a fixing rod.

[0006] Preferably, the end of the gripping rod away from the extension rod has an internal movable groove extending along the length of the gripping rod. A movable block is slidably disposed in the movable groove. Slider blocks are symmetrically fixed on both sides of the movable block. The inner wall of the movable groove has a sliding groove corresponding to the position of the slider, which slides and engages with the slider. The extension direction of the sliding groove is consistent with that of the movable groove.

[0007] Preferably, a limiting spring is fixedly connected to the side of the movable block near the inside of the grab rod, and the end of the limiting spring away from the movable block is fixedly connected to the inner wall of the movable groove. When the limiting spring is in its natural state, it can drive the movable block to return to the inside of the movable groove.

[0008] Preferably, the side of the movable block away from the limiting spring is fixedly connected to the safety rope via a fixing strap, and the fixing rod extends out of the end of the safety rope away from the fixing strap and is fixedly connected to the inner wall of the movable groove near the end of the grab bar, so as to prevent the safety rope from being completely retracted into the movable groove.

[0009] Preferably, a first threaded groove is provided on the outer side of the end of the gripper rod away from the extension rod. A movable cover is detachably fitted on the outer side of the first threaded groove. A second threaded groove is provided on the inner side of the movable cover, which is threadedly engaged with the first threaded groove. A connecting band is movably connected to the outer side of the movable cover by a movable pin. The end of the connecting band away from the movable cover is fixedly connected to the outer wall of the gripper rod to prevent the movable cover from being lost after disassembly.

[0010] Preferably, the extension rod is fixedly connected to the grab rod and the grab hook by welding or high-strength bolts.

[0014] The working principle and beneficial effects of this utility model are as follows: Before operation, the safety rope can be pulled out from the movable slot and put on the wrist. Even if wearing heavy insulating clothing reduces hand dexterity or causes slippage due to tension during operation, the safety rope can prevent the grip bar from slipping out of the hand. This ensures that in case of an emergency, the operator in front can be pulled away from the power source in time through the grab hook, guaranteeing the first rescue time.

[0015] After the operation is completed, the safety rope is released. The force of the limit spring returning to its original position can pull the movable block to slide along the slide groove to the inside of the movable groove. Then, the fixed belt drives the safety rope to automatically return to the movable groove. The fixed rod can prevent the safety rope from being completely retracted, avoiding difficulty in retrieving it next time. At the same time, after the movable cover is closed, it can protect the safety rope from dust and impurities, extending its service life.
