Description

Technical Field

[0001] The utility model relates to the technical field of overhead lines, in particular to a tool for crossing over an overhead power line. Background Art

[0002] The laying out and removal of overhead transmission lines often involves numerous crossings and spans. Ensuring safe crossings without disrupting the normal operation of the facilities being crossed is a critical safety issue. Currently, overhead lines typically use spanning gantry installations, which is time-consuming and lacks effective positioning control during crossings, making them prone to deviation and disorganization.

[0003] According to the announcement number CN 216162306 U, a portable overhead line crossing tool is disclosed. The patent fixes the first connecting ring and the second connecting ring to the outside of the utility pole by a first bolt. The tool is easy to carry and install, and the line is protected and limited by upper and lower rollers. However, the above patent uses bolts to connect various components to the outside of the utility pole, which is time-consuming and labor-intensive, affecting the fixing efficiency of the staff. In addition, the tool can only be fixed to the outside of utility poles of the same specifications, and can only limit lines of the same specifications, making the applicability of the crossing tool poor. Utility Model Content

[0005] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0006] Preferably, the slide groove is a straight groove, the slide groove is evenly and symmetrically distributed around the center of the fixed plate, and the interior of the slide groove is slidably connected to the slide rod.

[0007] Preferably, the top of the sliding rod extends to the top of the rotating plate and is fixedly connected to the baffle, the outer side of the sliding rod is slidably connected to the outer side of the limiting groove, and the limiting groove is an arc-shaped groove.

[0008] Preferably, the worm wheel is meshingly connected to the worm, the outer side of the worm is rotatably connected to the ear plate, and the worm is fixedly connected to the bottom surface of the support frame through the ear plate.

[0009] Preferably, a plurality of evenly distributed threaded holes are provided on the side surface of the guide rail, and the moving block is connected and fixed to the threaded holes on the side surface of the guide rail by bolts.

[0010] Preferably, the interior of the rectangular groove is slidably connected to the exterior of the connecting block, and the side surface of the connecting block is slidably connected to the exterior of the guide rod via a circular through hole.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model is provided with a fixed plate, a sliding rod, a clamping plate, a rotating shaft, a rotating plate, a worm gear and a worm. The worm gear drives the worm gear to rotate, which further rotates the rotating shaft and the rotating plate, so that the limiting groove pushes the sliding rod to move inside the sliding groove, driving the clamping plate to clamp and fix the outer side of the utility pole, effectively reducing the difficulty of overall installation and disassembly, and improving the work efficiency of the operator. At the same time, the movement of the sliding rod and the clamping plate can be used to clamp and fix utility poles of different radii, thereby enhancing the applicability of the overall device.

[0013] 2. The utility model also provides a support frame, a guide rail, a moving block, a guide rod, a spring and a movable roller. The movable roller cooperates with the fixed roller below to clamp and fix the line, which plays a role in limiting the route. The threaded holes on the guide rail are used to facilitate adjustment of the position of the moving block and change of the number of moving blocks. The line is set separately through the movable roller for subsequent maintenance, and the roller is used to prevent the line from moving to the edge of the corner and causing wear.
