[0001] The invention belongs to the technical field of cable tensioners, and in particular relates to an electric cable tensioner for power grid construction. Background Art

[0002] The wire tensioner, also known as the ratchet tensioner, is used to tighten the conductor during the installation of overhead lines. When in use, first loosen the wire rope or galvanized iron wire on the wire tensioner and fix it on the crossarm, clamp the conductor with wire clamps, and then turn the special wrench. Due to the anti-reversal effect of the ratchet, gradually wind the wire rope or galvanized iron wire around the ratchet drum to tighten the conductor.

[0003] The existing tensioner is to fix the wire at one end by a hook and connect the wire to the other end by a hook.

The hook at one end of the wire is placed into the wire storage housing 101 through the installation opening 111, so that the hook is inserted into the limit groove 205 at the lowest position of the winding shaft 201, and then the wire is pulled upward so that the guide enters between the two clamping plates 207 at the highest position, and then the second motor 109 is driven to drive the rotating rod 203 to rotate, and the positioning threaded rod 204 rotates to drive the moving rod 303 to move along the moving groove 211. The push ring 304 moves to drive the first limit plate 302 to move, and the moving tube 301 moves to drive the second wire clamping groove 305 to move, and the elastic reset member 306 is stretched until the moving tube 301 fits with the second retaining ring 210.

This process can realize the fixation of the hook, and then drive the first motor 106 to drive the winding shaft 201 to rotate, so that the wire is tightened. In this process The wire is tightened between the first limit plate 302 and the second limit plate 208. When the wire is completely tightened, the other end of the wire is fixed to the L-shaped connecting rod 112. This process can realize the automatic tightening of the wire. When the wire needs to be reused, the wire end of the L-shaped connecting rod 112 is untied, and then the first motor 106 is driven to rotate in the opposite direction to drive the winding shaft 201 to rotate in the opposite direction, so that the wire is released. When the wire between the first limit plate 302 and the second limit plate 208 is released, the second motor 109 is driven to rotate in the opposite direction to drive the rotating rod 203 to rotate in the opposite direction, and the positioning threaded rod 203 is locked. 04 reverse rotation drives the moving rod 303 to move reversely along the moving groove 211, pushing the ring 304 to move reversely, and under the action of the elastic reset member 306, the first limit plate 302 moves reversely, and the moving tube 301 moves reversely to drive the second wire clamping groove 305 to move reversely until the moving tube 301 returns to the initial state. During this process, the moving tube 301 continuously releases the wire in the first wire clamping groove 206. After the wire in the first wire clamping groove 206 is completely released, the hook is loosened so that the hook is released. At this time, the hook moves out of the limiting groove 205, and the automatic release of the wire can be completed at this time.
