Embodiment Construction

[0017] Refer to attached Figure 1~6 The aluminum wire tensioner includes a main body 1, a handle 2 and an inner tapered sleeve 3. The main body 1 has two semicircular bodies, and the two semicircular bodies are respectively provided with hinges 4 on both sides, which are hinged by hinges 4 and hinge pins 5. In one body, bosses 9 are provided at both ends of the main body 1 to enhance the strength of the main body 1. Protruding posts 6 are respectively provided on both sides of the rear of the main body 1, and screw rods 10 are installed for installing the handle 7. The main body 1 is provided with inner Cone hole 13, the inner taper hole taper α is 2-4 °.

[0018] The main body 1 is cast from alloy steel. The inner taper sleeve 3 is composed of two semicircular taper sleeves. The middle part of the inner taper sleeve 3 has an inner hole 14 for passing through and holding the wire 8. The outer taper sleeve 3 is provided with an outer tapered surface 15, and the outer tapered ...

Abstract

The invention discloses an aluminum wire tightener which relates to a wire stringing construction tool and can be used in a gap-type wire stringing construction. The aluminum wire tightener comprises: a main body, a handgrip and an inner cone sleeve. The main body possesses two-semicircle simplified bodies which are hinged into one body through a hinge. Protruding columns are respectively arranged on two sides of a rear part of the main body and a screw rod is installed so as to install the handgrip. The main body is provided with an inner taper hole. An inner cone sleeve is formed by two semicircle taper sleeves. A central section of the inner taper sleeve is provided with an inner hole. A male cone is arranged out of the inner cone sleeve. The male cone is matched with the inner taper hole arranged in the main body. The handgrip is sleeved on the screw rod which is located on the rear part of the main body and is fixed through a nut. The aluminum wire tightener is designed aiming at a special structure of a gap-type wire and a low sag characteristic of the wire. The design is reasonable and the structure is simple. The invention discloses a gap-type wire thread jamming and tightener. The tightener possesses the inner cone sleeve which can gradually clamp the wire as an increasing tension along a traction direction. During the stringing and the construction, the wire can be clamped and tensioned effectively. And there is no harm to a wire aluminum layer.

Description

technical field [0001] The aluminum wire tensioner of the invention relates to a wire stringing tool, which is applied to the wire stringing construction of gap type wires. Background technique [0002] Due to 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 wiring construction, it will cause irreversible damage to the conductor layer. In view of the above reasons, there is a need for an aluminum wire tensioner that does not damage the wires. Contents of the invention [0003] The object of the present invention is to provide an aluminum wire tensioner aimed at the above deficiencies, which is designed for the special structure of the gap type wire and the low sag characteristic of the wire. The aluminum layer does no harm. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] The aluminum wire tens...
