Detailed ways

The present invention is not limited by the following examples, and specific implementation methods can be determined according to the technical solutions of the present invention and actual conditions.

In the present invention, for the convenience of description, the description of the relative positional relationship of each component is described according to the layout of the accompanying drawing 1 of the specification. The layout direction of the graph is determined.

Below in conjunction with embodiment and accompanying drawing, the present invention will be further described:

As shown in Figures 1 and 2, the ratchet wrench for high-voltage transmission lines includes a two-way ratchet wrench, a fixed splint 1, a splint seat 2 and an insulating rod 3; the two-way ratchet wrench includes a handle 4 and a ratchet sleeve 5 fixed together , one end of the ratchet sleeve 5 is installed with a matching inner hexagonal sleeve 7, the fixed splint 1 is in the shape of a "V" with an upward opening, and the end of the handle 4 away from the ratchet sleeve 5 is rotatably mounted on the fixed splint through the pin shaft 6 1, and the axis of the pin shaft 6 is parallel to the axis of the ratchet sleeve 5, and the lower end of the fixed splint 1 is fixed with a splint seat 2 and an insulating rod 3 in sequence. The axis of the pin shaft 6 is parallel to the axis of the ratchet sleeve 5. When the insulating rod 3 is pushed and pulled to install or remove bolts and nuts, the ratchet sleeve 5 rotates evenly, so that the push-pull force is converted into the twisting of the bolts and nuts by the two-way ratchet wrench. The efficiency of force is maximized, reducing the labor intensity of operators when working at heights; the installation direction of the insulating rod 3 can be perpendicular to the axis of the pin shaft 6, so that it is more labor-saving for the operator to push and pull the insulating rod 3 when mounting and unloading bolts and nuts on the tower; During operation, the insulating rod 3 of different lengths can be replaced according to the voltage of the high-voltage line to ensure the personal safety of the operator; the inner hexagonal sleeve 7 and the ratchet sleeve 5 are for single-rotation power transmission; the inner hexagonal sleeve 7 can be used with twelve angles Hole sleeve instead.

According to actual needs, the above-mentioned ratchet wrench for high-voltage transmission lines can be further optimized or/and improved:

As shown in accompanying drawings 1 and 2, the two-way ratchet wrench also includes a reversing member 8; The two-way ratchet wrench is an existing known technology, and the effective rotation direction of the two-way ratchet wrench can be changed by the toggle of the reversing member 8; the labor intensity of the operators working at heights can be reduced.

As shown in accompanying drawing 1, the pin shaft 6 is a fully threaded bolt, the upper end of the fixed splint 1 is provided with a threaded hole matching the bolt thread, the handle 4 is provided with a through hole 9 larger than the major diameter of the bolt thread, and the bolt passes through the threaded hole and the through hole 9. The hole 9 installs the clamping plate 1 and the handle 4 together. The loading and unloading of the fixed splint 1 and the handle 4 is faster and more reliable like this; the threaded section of the fully threaded bolt in contact with the handle 4 can be polished into an optical axis, which can reduce the friction when the two-way ratchet wrench rotates and improve efficiency.

As shown in accompanying drawing 1, the bottom of splint seat 2 is cylindrical and is provided with external threads, and the top of insulating rod 3 is provided with internal thread grooves, and the bottom of splint seat 2 and the top of insulating rod 3 are fixedly installed together by threads. It is quicker and more convenient when changing insulating rod 3 like this.

The above technical features constitute the best embodiment of the present invention, which has strong adaptability and best implementation effect, and non-essential technical features can be increased or decreased according to actual needs to meet the needs of different situations.

The use process of the preferred embodiment of the present invention:

During operation, the operator boards the pole tower, holds the insulating rod 3 to operate, puts the inner hexagonal sleeve 7 on the bolts and nuts to be tightened or loosened, and pushes and pulls the insulating rod 3 to fasten or loosen. When fastening is required, place the reversing member 8 in the effective rotation direction in a clockwise state, push and pull the insulating rod 3, and only the clockwise rotation of the ratchet sleeve 5 will transmit power to the inner hexagonal sleeve 7 for fastening the bolts and nuts , while the counterclockwise rotation of the ratchet sleeve 5 will not transmit power to the inner hexagonal sleeve 7, and the inner hexagonal sleeve 7 will not rotate; when it needs to be loosened, put the reversing member 8 in the counterclockwise state where the effective rotation direction is , push and pull the insulating rod 3, only the counterclockwise rotation of the ratchet sleeve 5 will transmit power to the inner hexagonal sleeve 7 for loosening bolts and nuts, while the clockwise rotation of the ratchet sleeve 5 will not transmit power to the inner hexagonal sleeve Barrel 7, hexagon socket socket 7 keeps not turning. Operators can avoid power outages by performing low-potential operations. The invention is easy to operate and portable, saves a lot of manpower and material resources, avoids power loss, improves work efficiency, and brings intuitive economic benefits. Safe and reliable operation.
