Description

Technical Field

[0001] The utility model relates to the technical field of overhead lines, in particular to an electric lifting auxiliary hook for overhead line operators. Background Art

[0002] Overhead lines refer to a method of power transmission in which power, communication and other lines are erected above overhead poles or towers instead of being buried underground. It is one of the most common methods of power transmission and distribution. When using overhead lines, it is necessary to balance their cost advantages with safety, environmental and other factors, and take appropriate management and protection measures.

[0003] Existing related technologies often have the following defects: aerial work itself carries a high safety risk, especially in the power industry, where falls from heights and electric shock accidents are common safety hazards. Hooks are important lifting and fixing tools in aerial work, and their safety and reliability are directly related to the life safety of operators. With the rapid development of power facility construction, the amount of aerial work continues to increase, which puts higher requirements on work efficiency.

[0004] Therefore, the utility model provides an electric lifting auxiliary hook for overhead line operators. Utility Model Content

[0005] Based on the technical solution provided, we will describe in detail the hook device of this portable aerial work lifting device, which is specially designed to improve the safety of aerial work and integrates advanced automatic locking technology to ensure the safety of operators and equipment during aerial work.

The movable locking rod is connected to the movable locking block and is used to control the state of the movable locking block. The movable locking block is manually opened or closed, and is manually opened so that the V-block can be inserted to play a guiding role. When the drone drives the V-block to move upward through the ladder, due to gravity, the hook lock is in an open state, and the V-block drives the movable locking block to slide out upward. The rope threading hole is used for threading the insulating rope. The hook lock is rotatably connected to the hook body, and the hook lock is used to be subjected to an upward force when the rope is hung.

[0007] Preferably, the limit shaft is rotatably installed inside the movable locking block to limit the rotation range of the movable locking rod to prevent the movable locking rod from falling off due to excessive rotation range.

[0008] Preferably, the ball screw is inserted into the interior of the movable locking block and can rotate freely according to the movable locking rod. When rotated to the correct position, the ball screw head automatically pops out and snaps into the groove to control the position of the movable locking rod.

[0009] Preferably, the movable shaft is installed inside the movable locking block, and the movable locking rod rotates through the movable shaft, thereby reducing friction resistance, improving device flexibility, and reducing mechanical loss.

[0010] Preferably, the slide rail is installed on the inner side of the hook body, and the slide rail is the moving track of the movable locking rod. This device is provided to reduce friction so that the movable locking rod can run on the correct track.

[0020] Reference Figure 1-4 As shown, the utility model provides a technical solution: an electric lifting auxiliary hook for overhead line workers, including a hook body 1, a hook body 1, a movable locking rod 2, a rope threading hole 3, a hook lock 4, a limit shaft 5, a ball screw 6, a movable shaft 7, a slide rail 8, a V-block 9 and a movable locking block 10.

[0021] The following is a detailed description of its overall specific settings and functions.

[0022] In this embodiment: the hook body 1 is an important carrier connecting the various parts of the entire hook, and the functions of each part are presented based on the hook body 1.

[0023] Active locking rod 2: This device is connected to the active locking block 10 and controls the state of the active locking block 10. The active locking block 10 is manually opened or closed, and is manually opened so that the V-shaped block 9 can be inserted, which plays a guiding role. When the drone drives the V-shaped block 9 to move upward through the ladder, due to gravity, the hook lock 4 is in an open state, and the V-shaped block 9 drives the active locking block 10 to slide upward.

[0024] Rope threading hole 3: Mainly used to facilitate the threading of the insulating rope. The setting of the rope threading hole is conducive to the quick and stable connection between the hook and the device on the insulating rope, thereby improving the safety of high-altitude operations.

[0025] Hook lock 4: When the rope is hooked in and subjected to an upward force, the hook lock 4 is automatically locked to prevent the rope from accidentally falling off and improve the safety of the operation.

[0026] Limiting shaft 5: used to limit the rotation range of the movable locking rod 2 to prevent the movable locking rod 2 from falling off due to excessive rotation range, thereby reducing safety hazards.

[0027] The ball screw 6 can be freely rotated according to the movable locking rod 2. When it is rotated to the correct position, the head of the ball screw 6 automatically pops out and fits into the groove to control the position of the movable locking rod 2.

[0028] Active shaft 7: The active locking rod 2 rotates through the active shaft 7, which reduces friction resistance, improves device flexibility, and reduces mechanical loss.

[0029] Slide rail 8: The moving track of the movable locking rod 2. This device is provided to reduce friction so that the movable locking rod 2 can run on the correct track.

[0030] V-block 9: connects the hook and the ladder, the ladder is connected to a drone, and the drone drives the hook to the designated position.

[0031] Active locking block 10: the core component of the device. When the active locking block 10 is not driven to slide out by the V-shaped block 9, the hook lock 4 is in a locked state and cannot be opened because the side of the active locking block 10 is in close contact with one end of the hook lock 4. The hook lock 4 can only be opened after the active locking block 10 slides out.

[0032] Working principle: when in idle state, the movable locking rod 2 and the hook lock buckle 4 are in a closed state. When working, the movable locking rod 2 is pushed, and the movable locking rod 2 rotates to the appropriate position, and the ball screw 6 pops out and fixes it. The V-block 9 is inserted into the groove of the movable locking block 10. The drone is connected through the V-block 9. When the drone drives the device to lift, the movable locking block 10 is pulled upward due to gravity, and the hook lock buckle 4 automatically opens. The drone drives the device to mount the hook on the wire, and the drone evacuates with the V-block 9. At this time, under the action of force, the movable locking rod 2 and the hook lock buckle 4 are both in a closed state, and the movable locking block 10 is automatically locked. The utility model improves the safety of operation and prevents falling from heights. The hook is usually equipped with an automatic locking safety device to ensure that it will not accidentally fall off during lifting or fixing, thereby effectively preventing falling from heights. The occurrence of accidents has improved work efficiency. The perfect combination of hooks and drones has facilitated the operation of high-altitude workers, reduced the difficulty of work, improved work efficiency, and had strong carrying capacity. The hooks made of high-strength and lightweight alloy materials not only ensured sufficient carrying capacity, but also were light in weight and easy to operate, making high-altitude operations more convenient and reducing the risks of personnel operation. The combined use of hooks and drones can reduce the direct operation of workers at high altitudes, thereby reducing safety risks caused by improper operation or negligence, and simplifying the operating steps. The reasonable design and application of hooks can help simplify the steps and processes of high-altitude operations, making operations easier and more efficient. By introducing new technologies, the convenience and safety of the hooks are improved, and the hooks are cleverly combined with drones to expand the scope of use of the hooks.
