Abstract
The invention discloses a wire lifting support for a power transmission line. The support comprises two pairs of hoops, two support columns, an upper layer wire cross-arm and a lower layer wire cross-arm, wherein the hoops are fixedly connected to a tower. The opposite hoops are arranged at the bottoms of the support columns, and the support columns are arranged at the top of the tower in a sleeving manner through the hoops. The upper layer wire cross-arm and the lower layer wire cross-arm are obliquely arranged on the support columns. The upper end of the lower layer wire cross-arm and the middle position of the lower portion of the upper layer wire cross-arm are connected through a reinforcing plate. The bottom of the lower end of the lower layer wire cross-arm is provided with an insulator hanging ring. The bottoms of the two ends of the upper layer wire cross-arm are respectively provided with an insulator hanging ring. The wire lifting support for the power transmission line and the tower are integrally connected, the upper layer cross-arm and the lower layer cross-arm are obliquely arranged, the space is fully utilized, wires are lifted to the position above the top of the tower, the line cross and span distance is increased, the equipment investment is reduced, and a wire cross-arm arrangement problem of a special tower whose height is limited can be solved.
Description
Technical field
The present invention relates to electric force pole tower technical field, is a kind of transmission line wire lifting bracket specifically.
Background technology
Cause former crossing elimination to cross over distance because construction road surface raises or newly-built circuit passes through old wire below original transmission line wire and do not meet safety code requirement, often adopt the method changing high shaft tower to improve wires cross for this reason and cross over distance, increase power off time like this, increase the weight of the cost of overhaul, cause a large amount of waste and loss.
Summary of the invention
For solving the problem, the object of this invention is to provide a kind of transmission line wire lifting bracket, under the prerequisite not changing shaft tower, solving former crossing elimination and crossing over the not enough problem of distance, reducing power off time, reduce the cost of overhaul.
The present invention for achieving the above object, a kind of transmission line wire lifting bracket, comprise the two pairs of anchor ears be fixedly connected with shaft tower, two support columns, topping wire cross-arm and lower layer conductor cross-arm, the bottom of described support column arranges relative anchor ear respectively, support column is made to be enclosed within the top of shaft tower by anchor ear, described support column is obliquely installed respectively topping wire cross-arm and lower layer conductor cross-arm, the upper end of described lower layer conductor cross-arm is connected by stiffener with the centre position of the latter half of topping wire cross-arm, the lower end base of described lower layer conductor cross-arm arranges insulator link, bottom the two ends of described topping wire cross-arm, insulator link is set respectively.
As preferred technical scheme, Bending Processing is done at described topping wire cross-arm top, and Bending Processing sections transverse is in shaft tower, and the two ends insulator link of described topping wire cross-arm is respectively used to phase and limit phase conductor in suspension.
As preferred technical scheme, described stiffener is parallel with topping wire cross-arm, and stiffener does bending process, and bending part is consistent with lower layer conductor cross-arm incline direction.
Owing to adopting above technical scheme, the invention has the advantages that: when occupying few shaft tower length, transmission line wire lifting bracket of the present invention and shaft tower connect as one, and upper and lower two-layer cross-arm tilts to install, and makes full use of space resources, more than lifting wire to head of mast, improve crossing elimination and cross over distance, decrease equipment investment, and for limiting the special shaft tower of tower height, solve the Layout Problem of its wire cross-arm.
Accompanying drawing explanation
Now the present invention will be further described by reference to the accompanying drawings.
Fig. 1 is structural representation of the present invention.
