Description

Technical Field

[0001] The utility model relates to the technical field of power grids, in particular to a cable stripping device for high-altitude operations. Background Art

[0002] In the modern power transmission system, overhead transmission lines have become the core carrier for cross-regional transmission of electric energy due to their wide coverage and strong transmission capacity. These lines not only cover various densely populated areas such as cities and villages, but also cross complex geographical environments such as mountains and deserts. Their distribution shows significant dispersion and wide-area characteristics.

[0003] At the operational level, maintenance operations such as stripping and wiring overhead transmission lines are critical to ensuring the safe and stable operation of the power grid. Whether upgrading lines, connecting new equipment to the grid, or repairing damaged lines, the precise removal of the outer insulation of wires is an essential process. However, such operations within the industry are still primarily performed manually, a traditional model with significant limitations. According to power industry safety accident statistics, approximately 35% of injuries and deaths among power operation and maintenance personnel each year due to high-altitude operations are related to maintenance operations on live lines. Workers must perform operations on overhead conductors tens of meters high, facing not only the direct threat of falling but also the need to perform delicate operations in a strong electric field environment. Even wearing a full set of insulating protective equipment, it is difficult to completely avoid the risk of electric shock.

[0004] In the specific operation of cable stripping, existing technologies also have obvious shortcomings. Traditional stripping equipment generally lacks effective wire fixing devices. When workers strip wires at high altitudes, it is difficult to avoid uneven insulation stripping caused by the shaking of the wires. This operational instability may not only cause the risk of leakage, but may also damage the conductor structure due to operational errors, posing a risk of electric shock. Therefore, the development of specialized equipment that can adapt to the complex environment of high altitudes and has stable fixing and precise stripping functions has become an urgent need to improve the safety and efficiency of power operation and maintenance operations.

[0049] like Figure 1 、 2 , 3, 4, 6, 7 and 8: When the equipment is performing the stripping operation, the external vehicle equipment moves the base 1 to the appropriate position, and then the fixed clamp 8 in the fixed component "grasps" the wire. During this process, the movable mechanical arm 6 drives the fixed clamp 8 to adjust the height; when the wire falls into the fixed clamp 8, the motor drives the fixed worm 26 to rotate, and the rotation of the fixed worm 26 drives the connecting movable block 7 and the fixed clamp 8 to slide through the fixed worm gear 25 and the third double-thread screw 24, thereby achieving the fixation of the wire; when the wire between the fixed components is in a loose state, the fixed components slide to both sides respectively, thereby "straightening" the wire.

The setting of the belt ensures the synchronization of the rotation of the active rotating gear 9 and the driven rotating gear 10 on both sides; at this time, the active rotating gear 9 and the driven rotating gear 10 rotate in opposite directions; thereby achieving the opposite movement directions of the two rotating chucks 3; effectively solving the problem of difficulty in stripping operation during power grid maintenance in the prior art, and can effectively offset the stress of unidirectional rotation, thereby solving the problem of wire shaking during stripping; at the same time, it also solves the problem of wire shaking during stripping operation, and also solves the problems of low efficiency and high risk of manual maintenance.

The setting of the steel balls on the positioning clamp 16 can effectively reduce the friction force of positioning during the stripping process.
