Wire tightener for power equipment

Abstract

The invention discloses a wire tightener for power equipment. The wire tightener comprises a wire tightening box; second bearings are fixedly mounted on the left side and the right side of the interior of the wire tightening box; a second follow-up rod is movably mounted between the inner side walls of the two second bearings in a penetrating manner; and fixing plates are fixedly mounted on the surfaces of the left side and the right side of the top end of the wire tightening box. The fixing plates and sliding plates are connected through connecting bolts, the positions of the sliding plates on the surface of the fixing plates can be changed by adjusting the connecting bolts to be placed into first connecting screw holes in different positions, the distance between the two sliding plates is changed, and the applicability of the device is improved; metal wires with different diameters can be fixedly clamped on the surfaces of two heavy pressure rollers, so that the metal wires which are stored in or released from the wire tightening box can be subjected to heavy pressure flattening through the heavy pressure rollers, and therefore, it is guaranteed that the metal wires can be rapidly pulled out or stored. The wire tightening device is practical and suitable for wide application and popularization.

Description

technical field [0001] The invention is applicable to the field of auxiliary devices for electric equipment, and in particular relates to a wire tensioner for electric equipment. Background technique [0002] Tightening frame, also called ratchet tightening device, is used for tensioning wires in the construction of overhead line laying. The application fields of tensioning frame: construction, highway, bridge, metallurgy, mine, slope tunnel, shaft management and protection, etc. Mechanical equipment for construction works. [0003] The existing patent (publication number "CN201720846191.2") is a wire tensioner for electric equipment, including a wire tensioner, the end of the tensioner is provided with a splint, and one side of the splint is provided with a cylindrical movable Bolt, the bottom of the movable bolt is provided with a connecting shaft, the connecting shaft is embedded in the inside of the splint, the splint and the connecting shaft are movably connected throu...

AI Technical Summary

Problems solved by technology

[0004] But, still contain some problems in the above-mentioned patent: 1, because the diameter of different metal wires is different, when rotating and winding on the surface of tightening gear, the speed when receiving can be affected because of the unevenness of metal wires, and then may cause metal wires 2. Since the wire tensioner needs to manually collect the metal wire to tighten the surface of the gear when the wire tensioner receives the metal wire, it takes time and effort and affects the construction speed
