Description

Technical Field

[0001] The utility model relates to the field of electric power construction, in particular to a cable spacing retaining frame for electric power construction. Background Art

[0002] In order to prevent the adjacent cables in the air from contacting each other in the wind or to maintain the distance between the cables in some specific cases, the existing cable retainer includes a base frame, a clamping part at both ends of the base frame and an adjustment component. The clamping part includes a fixed claw and a movable claw that guides the movement. The adjustment component includes a rod-shaped part and a trapezoidal plug provided at the front end of the rod-shaped part. The guide part of the movable claw is an inclined surface. The trapezoidal plug pushes the guide inclined surface to move and then pushes the movable claw to approach the fixed claw. There are two existing ways to push the rod-shaped part to move. One is a threaded rod in the rod-shaped part, which is screwed on the base frame. The threaded rod is rotated by a tool to make the trapezoidal plug rise or fall. In this way, for aerial cables in a vibrating environment, the threaded rod is easy to loosen from the threaded hole, resulting in failure to maintain the cable spacing. In addition, screwing the threaded rod in the air is very time-consuming and laborious. The other is that multiple retaining frames are connected to form a closed shape, the tail of the rod-shaped part is an arc plate, and a fixed cylinder is arranged in the closed multiple retaining frames, and then the closed multiple retaining frames are pre-tightened to reduce the area enclosed by the closed shape, so that the fixed cylinder presses the arc plate until the movable claw and the fixed claw clamp the cable. This method introduces a fixed cylinder, which is very unfavorable for high-altitude operation. At the same time, hanging the fixed cylinder at high altitude greatly affects the appearance and increases the equipment cost.

The trapezoidal plug cooperates with the inner ends of the two guide plates. The push rod is guided and plugged into the base frame along the thickness direction of the base frame. The positioning mechanism includes a fixed plate 6 fixed to the bottom of the base frame and a gear 3 rotatably set on the fixed plate. The lower part of the push rod is a rack meshing with the gear. A sleeve 5 is radially welded to the side of the gear. The side of the gear has a plug-in hole. A plurality of positioning holes 4 coaxially distributed with the gear are provided on the fixed plate. A self-locking pin 7 positions and fixes the gear through the plug-in hole and the positioning hole.

[0019] When using the cable spacing retainer for power construction of this embodiment, two cables are placed between the fixed claw and the movable claw of the clamping part, a screwdriver is inserted into the sleeve as a lever arm, and the gear is rotated counterclockwise so that the trapezoidal plug of the push rod presses against the inclined surface of the inner end of the guide plate, thereby pushing the guide plate to move along the guide rail, so that the movable claw gradually clamps the cable on the fixed claw, and then, the self-locking pin is passed through the plug hole and the corresponding positioning hole to fix the gear. The self-locking pin locking method is suitable for vibration environment and the movable claw will not loosen.

[0020] In other embodiments, Figure 1-3 As shown, the lateral side of the fixed claw 13 has a guide hole structure, the guide hole includes a circular hole 12 and a gap 10 connecting a part of the circular hole with the outer arc surface of the fixed claw, and a limiting groove 11 connected with the gap is arranged on the outer arc surface of the fixed claw along the circumferential direction, and the limiting groove is a trapezoidal groove, and one end of the I-shaped connecting rod 17 is inserted into the guide hole along the lateral side of the fixed claw and hingedly arranged with the guide hole.
