Embodiment
The present invention is further detailed explanation below in conjunction with drawings and Examples.
As shown in the figure, this squirrel cage type jumper wire spacing rod, the lead heading spacing is 300mm, being suitable for the diameter of wire scope is ￠ 22～35mm, mainly comprise framework 1 and wire clip body 2, two parts of described framework 1 symmetry are fixed together by the connecting hole on the framework 1 22, second bolt 13, second plain washer 14, the second bullet pad 15, second nut 16 and second split pin 17.Second installing hole 23 that has on first installing hole 19 that has on the framework 1 and the wire clip body 2; by first bolt 7, first nut 8, first plain washer 9, the first bullet pad 10 and first split pin 11 framework 1 along the circumferential direction is fixed together with the end of one group of wire clip body 2 respectively, first bolt, 7 upper covers have protective sleeve 12.The junction of framework 1 and wire clip body 2 is installed with rubber link stopper 18, the front end of wire clip body 2 is provided with first pin-and-hole 24, first pin-and-hole 24 is separated and is formed slot, and an end of cover plate 5 is inserted in this slot, and second pin-and-hole 26 of cover plate 5, first pin-and-hole 24 link together by joint pin 6; Wire clip body 2 and cover plate 5 are provided with the rubber blanket chamber 25 that is used to install rubber blanket 4, have on the wire clip body 2 and pin the self-locking pin-and-hole 27 that pin 3 cooperates.
Operation principle: the body that is designed to of wire clamp adds cover plate press-down type card line, and wire clamp is whole to adopt the orthodrome transition, is mellow and full hemispherical through the chuck of polishing.It is that self-lock pin connects that cover plate has the bolt rivet clasp that changes in the past, removes the loaded down with trivial details structure of bolt-through wire clamp, becomes the one-sided concealed structure of elongated pin.So both save material and alleviated weight, promoted the appearance of product again.The hinge type structure is adopted at the chuck position of wire clip body, and the lead mode of holding with a firm grip adopts the self-lock pin formula.Be lined with rubber cushion blocks in wire clip body and the cover plate wire casing,, lead produced normal pressure by compression to rubber cushion blocks.Because it is 10 times of creep compliance that the compression of rubber has compensated the creep cushion block deflection of lead, makes wire clamp can hang on to lead.Consider for the wire clamp damping capacity, rubber cushion blocks adopt Changchun applied chemistry Research Institute and with " 1 " and " 2 " rubber, except that possessing good damping performance, ageing-resistant, wear-resisting and vibration absorption ability is all very strong.Adopt high-strength bolt to be connected between wire clamp chuck and the body frame, help the replacing of chuck like this, in order to improve anticorona ability, wire clamp material employing ZL102 is through polishing.
This product framework changes the two plate cast aluminium overall structures of hexagon in the past, adopts semi-open type cast steel bracing frame, under the situation that does not increase product weight, promotes the mechanical strength of conductor spacer.Four support arms are distributed in the conductor spacer center circumferential, have effectively disperseed the pressure of lead to wire clamp, four accessory installing holes 20 are distributed in the conductor spacer circumference uniformly on it, are used for extension as the installation of weight sheet.Support arm connects an anchor ear structure down, this structure can closely cooperate with the supporter steel pipe effectively, for making anchor ear structure and supporter accurately locate, not produce slippage, the through hole that forms in the anchor ear is provided with location notch 21, can match with the positioner on the supporter.Being connected of wire clamp and framework is not that simple single two crab bolts connect, and the rigidity that can produce aluminum casting and steel-casting like this contacts, and making fatigue of materials intensity become one must not irrespective problem.We have snapped in rubber link stopper 18 at the head of framework at this movable position, and make tile produce compression when mounted, and having the bolt of changing and frame ends stressed like this is elasticity tile damping carrying.Rational plate gap, accurate spiro keyhole position, the compression of rubber, rigidity connect and change flexible contact into, and these constitute the natural, tightly thick, reasonable of joint parts.Simultaneously, wire clamp is had ± 12 ° scope of activities in the tangential direction of lead, guardwire is without any damage under external force effectively.
In addition to the implementation, the present invention can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of requirement of the present invention.
