Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
nullProvided by Fig. 1 to Fig. 4，This utility model includes the first cross-arm 1，The second parallel cross-arm 2 and the 3rd cross-arm 3 it is respectively equipped with above and below first cross-arm 1，First cross-arm 1、Second cross-arm 2、3rd cross-arm 3 changes from small to big from top to bottom successively，First cross-arm 1、Second cross-arm 2、The both sides of the 3rd cross-arm 3 connect through firm bar 4，Constitute the first cross-arm 1、Second cross-arm 2、3rd cross-arm 3 forms trapezoidal structure，First cross-arm 1、Second cross-arm 2、3rd cross-arm 3 is closely connected through built-in lock button respectively with firm bar 4，First cross-arm 1、Second cross-arm 2、3rd cross-arm 3 is provided with the installing hole 5 of multiple installation insulator，First cross-arm 1 is connected ring 6 and is connected to anchor ear 7，Anchor ear 7 includes two semicircle anchor ears 8 of consistency from top to bottom，Connect through multiple connecting rods 9 between two semicircle anchor ears 8，One end of semicircle anchor ear 8 is connected to bandy radian hook 10，The radian plate 11 connecting two semicircle anchor ears 8 it is provided with between radian hook 10，The other end of semicircle anchor ear 8 is connected to the cylindrical bar 13 corresponding with radian hook 10 through spring 12，The middle part of cylindrical bar 13 is cased with the cam post 14 misaligned with its center，Cam post 14 is provided with handle 15，Constitute and stretch cylindrical bar 13 through spring 12，Cylindrical bar 13 is made to be stuck in radian hook 10，And outwards press handle 15，Cam post 14 props up the structure of radian plate 10.
Between described the first cross-arm 1 and the second cross-arm 2, between the second cross-arm 2 and the 3rd cross-arm 3, it is equipped with multiple fixed mount 16.
The side of first described cross-arm the 1, second cross-arm the 2, the 3rd cross-arm 3 is provided with intilted first groove 17, peripherally multiple the second grooves 18 caved inward successively in first groove 17, one end of firm bar 4 is provided with the first protruding block 19 mated with the first groove 17, and outer the placing of the first protruding block 19 is sequentially provided with multiple the second protruding block 20 mated with the second groove 18.
The first described groove 17 and the connecting portion of the first protruding block 19 are fixed through the bolt 21 internal through it.
When this utility model uses,
This utility model links together through first cross-arm the 1, second cross-arm the 2, the 3rd 3 three cross-arms of cross-arm, and with fixing form composition trapezium structure, one is the quantity that can increase and install insulator, two be first cross-arm the 1, second cross-arm the 2, the 3rd cross-arm 3 with firm bar 4 through built-in lock button compact siro spinning technology, an entirety can be formed, so as to all linked with one another, increase stability, it is not easy to come off, it is also possible to bear bigger weight.
And when closely cooperating, bolt, screw etc. need not be used to fix, it is only necessary to the first groove 17 matches with the second protruding block 20 with first protruding block the 19, second groove 18, is then closely plugged in together, the installation to cross-arm can be completed, greatly reduce the working strength of operator.
Further, when the wire on insulator is more, heavier, in order to more consolidate its stability, can also be connected through bolt 21 with the first protruding block 19 place at the first groove 17 equally.
The connected mode of first groove the 17, first protruding block the 19, second groove the 18, second protruding block 20 can conveniently operate installation, it is no longer necessary to carry aid, because the dangerous property when climbing electric pole or steel tower, construct aloft very inconvenient, and when being fixed, it is only necessary to an anchor ear is fixed on the first cross-arm 1, it is not necessary to bind anchor ear during each cross-arm, decrease the usage quantity of anchor ear, and steadiness is also very strong.
Traditional anchor ear is that two relative arc anchor ears link together through screw, fix on utility poles, cross-arm is connected again for installing cable etc outside anchor ear, but traditional anchor ear is thinner, it is used only to fix on utility poles, when cable is heavier, especially some outdoor high-voltage cables, its heavier mass, quantity is more, anchor ear is often difficult to bear its pressure brought, after a period of time, anchor ear will come off or damage, and anchor ear is generally fixed to the top of electric pole or signal tower, it it is work high above the ground, when whether installing or keep in repair, it is required for two people to operate together, and be not easy to fix very much.
Anchor ear of the present utility model is the anchor ear of two consistencies from top to bottom, the stability of anchor ear can be increased, when installing anchor ear, will not produce to loosen and rock, two anchor ears are connected by connecting rod, increase the gravity that anchor ear bears, to be used for carrying heavier weight, and then the cable of greater number and weight can be installed.
Anchor ear is no longer necessary to screw when fixing and fixes, because electric pole is cylindrical, fixes with screw, fixing anchor ear that can not be real, and anchor ear is less with the frictional force on electric pole, so traditional anchor ear steadiness is not strong.
This utility model is when installing anchor ear, one operator is with anchor ear, two anchor ears are blocked electric pole, then cylindrical bar 13 is pulled, along with the contractility of spring 12, cylindrical bar 13 is stuck in radian hook 10, and the size of spring 12 contractility is determined by the diameter of the distance between two anchor ears and electric pole, at cylindrical bar card 13 after radian hook 10, it is possible to anchor ear is fixed on utility poles.
In order to better fix anchor ear, outwards press handle 15, handle 15 drives cam post 14, cam post 14 is tightly against radian plate 11, cylindrical bar 13 is made to be stuck in radian hook 10 inflexibly, cam post 14 is enclosed within the outside of cylindrical bar 13, but it is not concentric with cylindrical bar 13, constitute the structure of a cam, so when pressing handle 15, cam post 14 larger diameter one end will prop up radian plate 11, complete fixing cylindrical bar 13, the relative screw of such connected mode, fixing tighter, one people just can complete Operation and maintenance, and it is easy for installation, aid need not be worn, dismantle also very convenient, greatly facilitate the operation of staff.
This utility model structure is ingenious, uses an anchor ear can fix multiple cross-arm, and can install multiple insulator, increases the quantity of conducting wire, and operator is easy for installation, reduces operator's danger in work high above the ground, and anchor ear is easy to use, it is not easy to come off.
