Abstract
A triangular hook for leads comprises a left rod and a right rod which are connected with each other through a hinge. Pay-off pulleys are arranged on the left rod and the right rod respectively, and a left lead screw and a right lead screw are hinged to the lower portions of the left rod and the right rod respectively and are connected with each other through an adjusting nut. According to the technical scheme, the leads are not easily damaged by the aid of the pay-off pulleys, potential safety hazards caused by easiness in damaging leads in maintenance at present are eliminated, the distance between the left rod and the right rod can be adjusted, the distance of the triangular hook can be adjusted, and the triangular hook is quite convenient to use.
Description
Technical field
The utility model relates to a kind of power circuit service kit, is used to lift the horizontal double bundle conductor triangle hook of lead when particularly relating to a kind of required level of service double bundle conductor.
Background technology
At present, the double bundle conductor of employing level transmits electric power during a lot of high-tension line, on changing straight line pole or tower, when insulator, adjustment suspension clamp, installation accessories, needs to promote lead by triangle hook.The triangle that the structural formula of the triangle hook that uses at present adopts round steel to make is fixed with cleaner respectively on leg-of-mutton two angles, because the cleaner cross section is less, easily lead is caused damage, has potential safety hazard.
Summary of the invention
The purpose of the utility model provides a kind of lead triangle hook of not fragile lead.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The utility model comprises left bar and the right bar that is connected through hinge, on left bar and right bar, pulley block is set respectively, and the bottom of described left bar and right bar hinged left screw mandrel of difference and right screw mandrel, and left screw mandrel is connected through adjusting nut with right screw mandrel.
Top at said left bar and right bar is provided with draw ring.
Adopt the utility model of technique scheme, adopt pulley block, make that lead is difficult for being damaged, lead easy damaged when having solved present maintenance and the potential safety hazard that causes; But also can adjust the spacing between left bar and the right bar, and promptly can adjust the line-spacing of triangle hook, very easy to use.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
Embodiment
As shown in Figure 1, the utility model comprises the left bar 1 and right bar 2 that is connected through hinge 5, on left bar 1 and right bar 2, pulley block 3 is set respectively; 4; Owing to the effect of pulley block, lead can not receive bigger axial force, so can guarantee not easy damaged of lead like this.
In addition, hinged respectively left screw mandrel 7 in the bottom of left bar 1 and right bar 2 and right screw mandrel 8 in the utility model, left screw mandrel 7 is connected through adjusting nut 9 with right screw mandrel 8, thereby can regulate the spacing between left bar and the right bar, promptly can adjust the line-spacing of triangle hook.
In addition, can also draw ring 6 be set, use with convenient on the top of left bar 1 and right bar 2.
During use, according to the line-spacing of horizontal double bundle conductor, rotation adjusting nut 9 makes the line-spacing of triangle hook identical with the line-spacing of lead, has so just reduced the distortion of lead when promoting lead, the problem of having carried the triangle hook of different spacing when having reduced maintenance simultaneously.
Claims (2)
1. lead triangle hook; It comprises left bar (1) and the right bar (2) that is connected through hinge (5); On left bar (1) and right bar (2), pulley block (3 is set respectively; 4), and the bottom of described left bar (1) and right bar (2) difference hinged left screw mandrel (7) and right screw mandrel (8), left screw mandrel (7) is connected through adjusting nut (9) with right screw mandrel (8).
2. lead triangle hook according to claim 1 is characterized in that: the top at said left bar (1) and right bar (2) is provided with draw ring (6).
