Abstract

The utility model relates to a wire clamping mean for damping oscillation of lines, which is characterized in that the upper part of a ship-shaped line groove (1) is transversely opened with a sliding groove (7), and at least two pin shafts (4) are penetrated through the lower part of a hanging plate (3); the line groove (1) is hung on the lower part of the hanging plate (3) by the sliding groove (7), and the upper part of the hanging plate (3) is hinged with the upper part of a pressing plate (2) by a screw bolt (5); a transverse conducting wire hole (8) is arranged between the lower end surface of the pressing plate (2) and the upper end surface of the line groove (1). The utility model can effectively reduce oscillation of the conducting wire and omits a vibration-proof hammer and an aluminum tape at the wire clamping point, and the utility model is suitable for line rods of hollow power lines of high voltage frames.

Description

Wire clamping means for damping oscillation of lines

The utility model relates to the wire clamp that uses in a kind of ultra-high-tension power transmission line.

In the prior art, electric pole is provided with porcelain vase, and wire clamp is hung below described porcelain vase, and high voltage power conductors is clamped the below of being fixed in porcelain vase by wire clamp.Because lead can be swung by the influence of wind-force, and then make the wire clamp place lead wearing and tearing and lead generation yield point occur, in order to prevent the lead swing effectively, on the lead of wire clamp both sides, be hung with stockbridge damper to eliminate the vibrations of lead, but stockbridge damper can increase the time of work high above the ground, has also increased the cost of engineering simultaneously.

The purpose of this utility model is to provide a kind of Wire clamping means for damping oscillation of lines that can eliminate vibrations automatically.

The technical solution of the utility model is: the middle part of ship shape wire casing laterally has sliding tray, at least two bearing pins pass the bottom of link plate and the bottom that described sliding tray hangs on wire casing link plate, the top of described link plate is provided with horizontal wire guide with the upper articulation of bolt and pressing plate between the upper surface of described pressing plate lower surface and wire casing.

The utility model compared with prior art has following advantage:

(1). owing to have sliding tray on the ship shape wire casing,, can eliminate the double swerve of lead so the wire casing of fixing cord can horizontally slip with respect to link plate.

(2). because wire casing is long and two ends wire casing do not have the fixing point of lead,, avoided the stressed yield point that produces of fixing point that causes owing to fixing cord in the groove of wire casing so lead can shake during play up and down.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing 1 is a structural front view of the present utility model;

Accompanying drawing 2 is the A-A direction cutaway view of accompanying drawing 1; Wherein:

[1]. wire casing; [2]. pressing plate; [3]. link plate; [4]. bearing pin; [5]. bolt; [6]. bolt; [7]. sliding tray; [8]. wire guide; [9]. the coaster fixing hole.

Embodiment: referring to accompanying drawing, the middle part of ship shape wire casing [1] laterally has sliding tray [7], and two bearing pins [4] pass the bottom of link plate [3] and the bottom that described sliding tray [7] hangs on wire casing [1] link plate [3].Described bearing pin [4] is two, and the spacing of these two bearing pins [4] is less than the length of sliding tray [7] so that the wire casing [1] of fixing cord can be slided with respect to link plate [3] when double swerve, when eliminating the lead swing at the stress at wire clamp place.The top of described link plate [3] can rotate pressing plate [2] around bolt [5] with the upper articulation of bolt [5] with pressing plate [2] for axle, the lower surface of described pressing plate [2] is to be the circular arc in the center of circle with bolt [5].When sliding when an end of lead stressed (for example lead disconnection) and with respect to wire casing [1], pressing plate [2] is promptly to a direction swing, and allow lead significantly to slide, prevent because lead disconnects, and wire clamp with lead fixed on electric pole and make electric pole be subjected to the not rupturing pulling force of direction on one side, forget about it electric pole.Be provided with horizontal wire guide [8] between the upper surface of described pressing plate [2] lower surface and wire casing [1], lead promptly pass this wire guide [8] and under the pressure of pressing plate [2] with lead fixed on wire clamp.Described link plate [3] is positioned at sliding tray [7] and locates to have coaster fixing hole [9], and being used to put on the coaster of tight lead also has a hole, and available bolt passes these two holes this wire clamp and slip car are connected to a fixed.The top of described link plate [3] is provided with the bolt [5] that is used to hang on porcelain vase.
