Description

Technical Field

[0001] This utility model relates to the field of high-altitude work equipment technology, and in particular to a high-altitude work rope slack hook. Background Technology

[0002] Aerial work rope slack hooks are devices specifically designed for aerial work to ensure the safety of workers. These devices are typically designed to be both robust and lightweight, making them easy to carry and use. The main function of aerial work rope slack hooks is to provide safety assurance. They allow workers to connect to a fixed point via a safety rope when needed to prevent accidental falls. At the same time, the metal buckle design ensures a secure connection between the safety rope and the fixed point, further enhancing safety.

[0003] To this end, China has applied for patent number CN2190186Y, which discloses a high-altitude operation rope easing hook for a suspended work seat. It has a horseshoe-shaped hook body with a rope groove on the back of the hook body, a rope hole at one end, a rope turning port and a fixed pulley at the other end, and is equipped with a protective rope ring and inner and outer rope stop rings. It is used to replace the rope knot combination to realize the easing and lowering operation of the suspended work seat. It is simple, flexible, safe and reliable, and easy to learn and understand.

[0004] Modern high-altitude work rope slack hooks can basically meet people's needs, but some problems still exist, as detailed below:

[0005] 1. The problem of the self-locking of the slack hook for high-altitude work ropes: In order to facilitate operation during high-altitude work, it is sometimes necessary to stop in mid-air. At the same time, if the operator loses balance in the air or falls accidentally, an emergency stop is required for adjustment. The slack hook for high-altitude work ropes cannot lock the rope and stop the operation.

[0006] 2. The problem of difficulty in suspending and connecting the slack hook of the high-altitude operation rope: When performing high-altitude operations, it is necessary to connect the slack hook to other structures, such as the safety rope on the user. The slack hook of the high-altitude operation rope is difficult to connect to other components and ropes quickly, and the operation requires the use of traditional knots, which is complicated. Utility Model Content

[0007] The purpose of this utility model is to provide a high-altitude work rope slack hook to solve the defects of existing high-altitude work rope slack hooks that are difficult to self-lock and difficult to suspend and connect.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-altitude operation rope slack hook, including a shell;

[0009] The housing has a control structure installed inside, and a handle is fixed to the top of the housing. The handle has a through hole.

[0010] The grip has a self-locking structure installed inside. The self-locking structure includes a moving part, a connecting rod, a pressing plate, a first spring, and a pointed cone. The moving part is installed inside the grip, and a connecting rod is fixed to one side of the moving part.

[0011] A pressing plate is fixed to one side of the connecting rod, a first spring is installed on the outside of the connecting rod, and a connecting structure is installed at the bottom of the outer casing.

[0012] When using, first pass the rope through the through hole, then go counterclockwise around one side of the second pulley and lock it into the second slot, then go clockwise around the other side of the first pulley and lock it into the first slot. Hold it with your hand. The safety rope worn by the user can be fastened in the connecting ring and locked with the limit rod to prevent it from falling off. When falling, hold the handle and press the pressure plate inward. When you release your hand, the pointed cone will be inserted into the rope to lock it in place.

[0013] Furthermore, the control structure includes a first rotating shaft, a first pulley, a first slot, a second rotating shaft, a second pulley, and a second slot. The first rotating shaft is fixed to the bottom inside the housing, and the first pulley is installed on the outside of the first rotating shaft. The first slot is formed on the outside of the first pulley. The second rotating shaft is installed at the top inside the housing, and the second pulley is installed on the outside of the second rotating shaft. The second slot is formed on the outside of the second pulley. This structure can reduce rope wear and ensure smooth rope operation.

[0014] Furthermore, the first spring is helical in shape, allowing it to be stretched and compressed.

[0015] Furthermore, the first spring and the moving part form an elastic connection, which facilitates the repositioning of the moving part.

[0016] Furthermore, a pointed cone is fixed to one side inside the movable component. The pointed cones are arranged at equal intervals on one side inside the movable component, and their tips can extend into the inside of the wire hole to fix the rope inside the wire hole.

[0017] Furthermore, the connecting structure includes a rotating rod, a limiting block, a connecting ring, a sliding groove, a limiting rod, a second spring, and a toggle block. The rotating rod is installed at the bottom of the outer casing, a limiting block is welded to the top of the rotating rod, a connecting ring is welded to the bottom of the rotating rod, a sliding groove is formed inside one side of the connecting ring, a limiting rod is installed inside the sliding groove, a second spring is fixed to the top of the limiting rod, and a toggle block is welded to one side of the top of the limiting rod, which can be used to connect other ropes.

[0018] Furthermore, the outer diameter of the limiting rod is smaller than the inner diameter of the sliding groove, and the limiting rod and the sliding groove form a sliding structure, allowing the limiting rod to rise and fall, which facilitates suspension and prevents it from falling off.

[0019] This utility model provides a high-altitude work rope slack hook, which has the following advantages: The control structure inside the outer shell of this high-altitude work rope slack hook can reduce rope wear and balance tension in multiple directions, ensuring the smooth operation of the rope. A self-locking structure is installed inside the handle to fix the rope and prevent the rope from slipping quickly, causing the user to lose balance or fall. The press-slide-release lock design allows the user to easily free their hands to perform other operations when the rope stops, making it more convenient to use. The connection structure at the bottom of the outer shell facilitates connection and prevents the ropes from tangling, avoiding safety hazards.

[0020] By installing a sliding movable part inside the handle, and connecting it to the pressing plate via a connecting rod on one side of the movable part, the pointed cone extends into the cable hole to fix the rope inside the cable hole. By compressing the first spring, the pointed cone can be pushed away from the rope via the connecting rod and the movable part, making it easier for the user to descend. After stopping the pressing, the first spring returns to its original state, and the movable part can be reset, thereby achieving the purpose of self-locking of the high-altitude operation rope slack hook.

[0021] By installing a rotatable rotating rod at the bottom of the outer casing, the limiting block can prevent the rotating rod from falling off the bottom of the outer casing. Lifting the actuating block can cause the limiting rod to slide in the sliding groove and squeeze the second spring. After suspension, releasing the actuating block will cause the second spring to return to its original shape and push the limiting rod to lock into the sliding groove, preventing the rope suspended in the connecting ring from falling off. This achieves the purpose of facilitating the suspension connection of the high-altitude operation rope slack hook. Attached Figure Description
