Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Please refer to fig. 1 to 3, the utility model discloses a cable maintenance and wire-changing device, which is suitable for hanging a maintenance cable 2 by using a fixed cable 1 as a support, wherein the cable maintenance and wire-changing device 3 comprises a hook unit 31, a fixed unit 32, a moving unit 33, and an actuating unit 34.

The fixed cable 1 is located above the maintenance cable 2, and a plurality of connecting wires are arranged between the fixed cable 1 and the maintenance cable 2 to maintain the level of the maintenance cable 2.

The hook unit 31 includes a support end hook 311 separably connected to the fixed cable 1, and a hanging end hook 312 separably connected to the maintenance cable 2, and can hook the fixed cable 1 and the maintenance cable 2, respectively. The supporting end hook 311 and the hanging end hook 312 respectively have a hooking portion 313, an extending section 314 and a free section 315, and both ends of the extending section 314 are respectively screwed with the hooking portion 313 and the free section 315 to adjust the hooking depth. And a plurality of anti-slip parts 316 arranged at intervals are arranged on the inner side surface of the hooking part 313.

The fixing unit 32 includes a fixing seat 321 connected to the supporting end hook 311, and an accommodating space 322 surrounded and limited by the fixing seat 321, wherein the accommodating space 322 is used for accommodating the actuating unit 34. The moving unit 33 includes a moving rod 331 connected to the hanging hook 312, and a moving screw 332 disposed on the surface of the moving rod 331.

The actuating unit 34 is connected to the fixing unit 32 and the moving unit 33, respectively, and controls the relative positions of the moving rod 331 and the fixed base 321. The actuating unit 34 includes a first rotating body 341 disposed in the accommodating space 322 of the fixed base 321, a first through hole 342 disposed in the first rotating body 341, a first screw 343 disposed at an inner edge of the first through hole 342, an actuator 344 for rotating the first rotating body 341, a controller 345 for controlling the rotation of the actuator 344, and an accumulator 346 for supplying power to the actuator 344. The moving screw 332 and the first screw 343 are engaged with each other so that the position of the moving rod body 331 can be changed when the first rotating body 341 is rotated.

The actuator 344 is a small motor connected to the second rotating body 347, and the outer walls of the first rotating body 341 and the second rotating body 347 are provided with a tooth structure that is engaged with each other, so that the actuator 344 controls the rotation of the first rotating body 341. In practice, bevel gears may be used as the tooth-coupled structure of the first and second

rotating bodies

341 and 347, but this should not be construed as a limitation.

When the supporting end hook 311 hooks the fixed cable 1 and the hanging end hook 312 hooks the maintenance cable 2, the hanging end hook 312 restricts the movable rod 331 from rotating, so that the first rotating body 341 cannot drive the movable rod 331 to rotate.

When the movable screw 332 and the first screw 343 are engaged with each other and the first rotating body 341 cannot drive the movable rod 331 to rotate, the rotation of the first rotating body 341 will change the telescopic position of the movable rod 331, so that the maintenance and replacement device uses the fixed cable 1 as a support to lower the old maintenance cable 2 to the ground and raise the new maintenance cable 2 to the top.

Further preferably, the accumulator 346 is a lithium battery disposed in the accommodating space 322, the controller 345 is a control button disposed on the fixed base 321, the accumulator 346 can provide electric power for rotating the actuator 344, and the controller 345 can control the direction of rotation of the actuator 344.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
