Specific embodiment

With reference to the accompanying drawing, specific embodiment of the utility model is described in further detail:

Embodiment one

As shown in Figure 1, as shown in Figure 1, trees distance-measuring device hanged hook under trolley wire to line, including support arm and Interior clamping device, the support arm include cross bar 1, and cross bar 1 is horizontally disposed, and 1 both ends of cross bar are separately installed with the first torsional spring hinge Chain 2 and the second torsional spring hinge 3, hinged first strip 6 of the first torsional spring hinge 2, hinged second strip 5 of the second torsional spring hinge 3；It is described Cross bar 1, the first strip 6, the second strip 5 be located in same vertical plane, and the first strip 6, the second strip 5 are located at cross bar 1 Downside；First strip 6, the second strip 5 lower end be respectively equipped with hanging hole；First strip 6, the second strip 5, cross bar 1 Half frame of the elasticity an of half opening is surrounded, the opening width of nature lower half frame is less than 1 length of cross bar, and Fig. 1 is half frame Be open the state being softened.

Interior clamping device is equipped in half frame, the interior clamping device includes the reed reed an of flexible arc 4, the cambered surface of 4 evagination of reed is towards cross bar 1, and the cambered surface of indent towards the opening of half frame, consolidate by one end of the reed 4 It is scheduled on the inside of the second strip 5, the inner wall sliding contact of the other end and the first strip 6；Reed 4 and the second strip 5, the first strip 6, cross bar 1 is in same vertical plane；The side of 4 indent of reed is equipped with multiple squeezing rollers 9, the squeezing roller 9 Axis it is horizontally disposed and vertical with the vertical plane where reed 4 and cross bar 1, multiple squeezing rollers 9 along reed 4 uniformly point Cloth.

When use, as shown in Figure 1, both sides strut respectively outward by the first strip 6, the second strip 5, reed 4 The other end is contacted with the inner wall of the first strip 6 always under the elastic force of itself.When half frame opening open, then reed 4 also by Release is opened, and by open 4 sets of reed on trolley wire, is then unclamped the first strip 6, the second strip 5, is utilized the first torsional spring The elastic force of hinge 2 and the second torsional spring hinge 3 mutually draws close the lower end of the first strip 6, the second strip 5, while the first strip 6, Second strip 5 squeezes reed 4 and collapses, and the elastic force of the first torsional spring hinge 2 and the second torsional spring hinge 3 needs obviously than the bullet of reed 4 Power is big.It is stuck on trolley wire using multiple squeezing rollers 9 in reed 4.Then measuring instrument is hung over into the first strip 6, In the lower end hanging hole of two strips 5.

In order to protect the external protection of cable, the axis of the squeezing roller 9 is fixed on reed 4 by spring 10, institute The spring 10 stated is mounted in the cambered surface of 4 indent of reed in spoke-like.10 one end connecting bushing of spring, axle sleeve is actively set on crowded The shaft end portion of pressing roller 9.

Embodiment two

As shown in Fig. 2, the stabilization in order to keep hook, does not overturn on aerial cable, needs that decentralization will be linked up with, because This, on the basis of example 1, hinged first extension bar 8 of hanging hole of first strip 6, second strip 5 The lower end of hinged second extension bar 7 of hanging hole, first extension bar 8 and the second extension bar 7 is respectively equipped with lower hanging hole.Measuring instrument Device is hung on lower hanging hole.And the first extension bar 8 and 7 lower end of the second extension bar can close up, and be fixedly connected, also not with anti-canting It can be fallen from cable.When installation, the first extension bar 8 and the second extension bar 7 can be collapsed respectively to the first strip 6, At second strip, 5 position.

General overhead line has certain sag, thus electric wire be not it is horizontal, to prevent hook from sliding along cable, therefore Need to increase the frictional force of contact surface.As shown in figure 3, the contact for increase with cable is close, can be slided on cable to prevent hook Dynamic, the wheel face of the squeezing roller 9 is equipped with multiple parallel annular lines, axis of the annular lines perpendicular to squeezing roller 9.
