CN201556888U - Half tension tensioner - Google Patents

Abstract

The utility model discloses a semi-tension type compensator which comprises a support (1), crossing grooves (2), a brake pad (3) and a pulley (4), wherein a row of crossing grooves (2) are arranged below the support (1); and the brake pad (3) and the pulley (4) are respectively arranged at two inner side edges of the crossing grooves (2), facing to each other. When a cable spans a barrier, the semi-tension type compensator is arranged in front of the barrier, and a lead passes through the crossing grooves (2) and is positioned between the brake pad (3) and the pulley (4). The semi-tension type compensator has simple structure, convenient operation, fast construction speed and adjustable tension; the spanned object is steady; and the safety of despooling workers is greatly improved.

Description

Half tension tensioner

technical field

The utility model relates to an auxiliary tool for electric facilities, in particular to a semi-tension type elastic device.

Background technique

As we all know, in the line construction, payout is the most basic work, tension payout technology is a common technology, especially used in high-voltage power lines. During the unwinding process, the wire may have to cross some obstacles. Before the wire crosses the obstacle, in order to avoid damage to the wire or damage to the object to be crossed, it is necessary to use an elastic device to assist the crossing, and the tension of the elastic device should not be too large. Otherwise, it is easy to cause the objects to be overturned, and the construction safety cannot be guaranteed.

Contents of the invention

The purpose of the utility model is to provide a half-tension tensioner with adjustable tension, enhanced operational stability, and guaranteed construction safety.

The technical solution of the utility model is: the elastic device includes a bracket, a crossing groove, a brake pad and a pulley, a row of crossing grooves is installed under the bracket, and brake pads and pulleys are respectively installed on the two inner sides of the crossing groove.

In the semi-tension type elastic device of the present utility model, a group of pulleys arranged in a line are installed on the inner side of the crossing groove.

When the cable crosses the obstacle, install this half-tension tensioner in front of the obstacle, and let the wire go through the crossing slot between the brake pad and the pulley.

The utility model has the following advantages: 1. The structure is simple, the operation is convenient, and the construction speed is fast; 2. The tension is adjustable, the objects to be spanned are stable, and the safety of the pay-off personnel is greatly improved.

Detailed ways

As shown in Figure 1, the tensioner includes a bracket 1, a crossing groove 2, a brake pad 3 and a pulley 4, a row of crossing grooves 2 is installed under the bracket 1, and brake pads 3 are respectively installed on the two inner sides of the crossing groove 2 facing each other. and pulley 4.

In the semi-tension type elastic device of the present utility model, a group of pulleys 4 arranged in a line are installed on the inner side of the crossing groove 2 .

When the cable crosses an obstacle, install the semi-tension type tensioner before the obstacle, and allow the wire to pass through the crossing groove 2 and be located between the brake pad 3 and the pulley 4.

Claims (2)

1. A semi-tension tensioner, characterized in that the tensioner includes a bracket (1), a crossing groove (2), a brake pad (3) and a pulley (4), and a row of crossing grooves is installed under the bracket (1) (2), the two inner sides of the crossing groove (2) are oppositely installed with brake pads (3) and pulleys (4). 2. The semi-tension tensioner according to claim 1, characterized in that: a set of pulleys (4) arranged in line are installed on the inner side of the crossing groove (2).
