Abstract
The utility model discloses an adjustable cross arm suspension string holder, which comprises a crow rod device and a cross arm clamp, wherein relative distance between screw rods is changeable. The utility model has the advantages that: the adjustable cross arm suspension string holder has a compact design and an adjusting function, can be fixed, is safe and reliable, and is suitable for linear insulator replacement on a gantry rod or a corresponding cross arm on a power transmission line.
Description
Technical field
The utility model relates to a kind of live line working Work tool, particularly a kind of adjustable cross-arm suspension string holder.
Background technology
Cross-arm is a part important in the shaft tower, and its effect is to be used for installing insulator and gold utensil, with support conductors, lightning conducter, and makes it the safe distance that keeps certain in accordance with regulations.The kind of cross-arm is a lot, and its width, each is different for size, thus we also be not quite similar changing the jig that uses on the insulator, just as changing the jig that insulator uses and the jig that uses is just different in the cross-arm place at iron tower on H-frame pole.Though the above circuit of 35kV uses iron tower more now, but because design and consideration cost problem, also exist a large amount of H-frame poles on the 35kV-220kV transmission line now, and the width of H-frame pole is again because electric pressure, the tower erection mode, tonnage, differences such as force request and being not quite similar, though therefore now also have some to be exclusively used in the jig of H-frame pole, as existing straight line card and the U type card that generally uses, its structure all is to be made of two screw mandrels and fixed cross-arm card, because the distance between two screw mandrels on the fixed cross-arm card is fixing, and because the width of H-frame pole varies, this has just caused a cross-arm suspension string holder can only be applicable to a kind of H-frame pole.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of adjustable cross-arm suspension string holder that can be applicable to multiple H-frame pole or similar shaft tower is provided.
A kind of adjustable cross-arm suspension string holder comprises lead screw device, the cross-arm card, and its structural feature is: the relative distance between the described screw mandrel is transformable.
The adjustable cross-arm suspension string holder of this structure because the relative distance between two screw mandrels is transformable, thereby can make it be applicable to the cross-arm of different in width.
The variable implementation of relative distance between the described screw mandrel has a lot, below is two kinds of forms that the applicant provides:
A kind ofly be: described cross-arm card is for changing the cross-arm card of length.
By the length of change cross-arm card, thereby make the distance between the screw mandrel that is fixed thereon realize changing.
The change of the length of described cross-arm card is by adopting two-part to constitute on the cross-arm card, be distributed with respectively on two sections cross-arm card along the axially extended hole of cross-arm card, connecting with keeper between the two cross-arm cards.
In use,, select the docking location of two sections cross-arm cards, with keeper locking, then carry out the fixing of cross-arm jig more in a conventional way then according to the length of the required cross-arm card of the width selection of cross-arm.
Another kind is: the position-adjustable of described screw mandrel on the cross-arm card.
By changing the position of screw mandrel on the cross-arm card, also can realize changing the relative distance between the screw mandrel.
Described screw mandrel is in the position adjustments of cross-arm card, by a plurality of screw mandrel fixtures is set on the cross-arm card.
By a plurality of screw mandrel fixtures is set on the cross-arm card, screw mandrel can be fixed on diverse location on the cross-arm card, thereby reaches the distance that changes between the screw mandrel, to adapt to the cross-arm of different width.
The screw mandrel fixture of described cross-arm card is a draw-in groove.
Described adjustable cross-arm suspension string holder also includes and is used for fixing whole cross-arm suspension string holder at the motionless fixture of card good position.
Described fixture is a kind of crozier, and this crozier is fixed on the cross-arm card with keeper.
In sum, the following compared to existing technology advantage of the utility model:
The design of this jig is light and handy, have regulatory function, can fix again, and is safe and reliable, is applicable to the operation of changing the straight line insulator on H-frame pole on the transmission line or the corresponding cross-arm.

Embodiment
Below in conjunction with embodiment the utility model is described in more detail.
A kind of adjustable cross-arm suspension string holder comprises lead screw device 1, cross-arm card 2.A plurality of screw mandrel fixtures 3 is set on the cross-arm card.Described screw mandrel fixture is the draw-in groove structure.Lead screw device can be fixed on the screw mandrel fixtures different on the cross-arm card.Described adjustable cross-arm suspension string holder also includes and is used for fixing whole cross-arm suspension string holder at the motionless fixture 4 of card good position.Described fixture is a kind of crozier, and this crozier is fixed on the cross-arm card with keeper.
It is same as the prior art that present embodiment is not stated part.
