Embodiment Construction

[0017] Reference attached Figure 1~6 , The aluminum wire tensioner includes a main body 1, a handle 2 and an inner cone sleeve 3. The main body 1 has two semicircular cylinders. The two semicircular cylinders are respectively provided with hinges 4, through hinges 4, and hinge pins 5. The main body 1 is hinged into a whole body. Both ends of the main body 1 are provided with bosses 9 to enhance the strength of the main body 1. On both sides of the rear part of the main body 1 are respectively provided convex posts 6 with screws 10 for installing the handle 7, and the main body 1 is provided There is an inner taper hole 13, the taper α of the inner taper hole is 2-4°. The main body 1 is made of alloy steel casting. The inner cone sleeve 3 is composed of two semicircular cone sleeves. The inner cone sleeve 3 has an inner hole 14 in the middle for inserting and clamping the wire 8. The inner cone sleeve 3 is provided with an outer cone surface 15 which is connected to the outer ...

Abstract

The invention discloses an aluminium wire tightener, which relates to lead stringing construction tools, is applied to gap type lead stringing construction and comprises a body, a handgrip and an inner taper sleeve. The body is provided with two semicircular cylinders which are hinged into one by a hinge; two sides of the rear part of the body are provided with a convex pillar and a screw rod respectively for mounting the handgrip; and an inner taper hole is formed in the body. The inner taper sleeve consists of two semicircular taper sleeves; the middle part of the inner taper sleeve is provided with an inner hole; and the outer part of the inner taper sleeve is provided with an outer tapered face which is matched with the inner taper hole arranged in the body. The handgrip is sleeved and arranged on the screw rod on the rear part of the body and is fixed by a nut. The aluminium wire tightener is designed according to the special structure of a gap type lead and the low sag property of the lead, has a reasonable design and a simple structure, is a gap type lead clamping and tightening device, is provided with the inner taper sleeve which gradually clamps and tightens the lead with the increase of a tensile force in a tension direction, can effectively clamp and tighten the lead in the stringing construction and does not cause damages to an aluminium layer of the lead.

Description

Technical field [0001] The aluminum wire tensioner of the present invention relates to a wire stringing construction tool, which is applied to the wire stringing construction of gap type wires. Background technique [0002] Because of the special structure of the gap-type conductor and the low sag characteristics of the conductor, if the wire is tightened with ordinary construction tools during the overhead construction, it will cause irreversible damage to the conductor layer. In view of the above reasons, an aluminum wire tensioner that does not cause damage to the wire is needed. Summary of the invention [0003] The purpose of the present invention is to provide an aluminum wire tensioner for the above-mentioned shortcomings, which is designed for the special structure of gap-type conductors and the low sag characteristics of the conductors. During the wire construction, the conductors can be effectively held and aligned. The aluminum layer does not cause harm. [0004] The al...
