The invention has the advantages of scientific structure, reasonable design, reliable installation, smooth operation, wide lifting range and high operating efficiency, and is suitable for single-side lifting or simultaneous double-side lifting of ultra-high voltage (UHV) transmission line steel angle high towers or tubular towers.
Description
Technical field
The invention belongs to power domain, relate to the upright used pole of iron tower of group of UHV transmission line construction, 360 ° of rotations of the two rocking arms of backguy pole in especially a kind of inner suspension.
Background technology
The iron tower group cube formula of extra-high voltage has nothing in common with each other both at home and abroad at present, send the history of five more than ten years of power transformation industry and the accumulation of construction experience and the group tower mode of the constituent parts that precipitation makes to have nothing in common with each other, but generally speaking nothing more than the pole that several forms such as outer floated, the exceedingly high formula of interior backguy inner suspension formula, external cable inner suspension formula, external cable, exceedingly high rocker arm, inner suspension external cable rocker arm and rocking arm be rotary are arranged, and the tower that constituent parts is accustomed to according to own difference on the basis of these several poles, the difference of type improve again and develop.
The common issue with that the pole of existing several forms exists is: guy structure form in suspending is owing to limited by landform, and it is bigger to cause the external cable pole to take up an area of; The rocking arm pole is played hanging piece can not draw outward and can only vertically lift by crane because landform limits, moreover must bigger skew can not be arranged in the vertical lower end of arm by a hanging piece; And owing to be subjected to the restriction of complex-terrain, Zu Zhuan quilt plays the place that tower crane spare can only be assembled in permission sometimes.
By retrieval, the following several pieces of publication documents close have been found: 1, a kind of circular pipe type inner suspended holding pole (CN101545329) with present patent application, connect to form in turn through bolt by suspension base, hypomere, straightway, epimere and knuckle arm assembly, straightway is connected to form through bolt by a plurality of standard paragraphs again, straightway, epimere and hypomere all mainly are welded by pipe, it have in light weight, mechanical property good, be convenient to the advantage of assembly and disassembly.2, a kind of inner suspension combined type pole (CN201161866), comprise the body of rod, boom hoisting, girdle ring and suspension base, it is characterized in that the body of rod is made up of a main rod body 2 and the secondary body of rod 4, connect by a cross articulated mounting 3 that girdle ring 6 is positioned at the top of the secondary body of rod between the two.The main rod body of this combined type pole can be rotated about 20 ° angle respectively around X-axis, Y-axis in the hinged place, can regulate the inclination angle with four faces of iron tower arbitrarily, has been convenient to the tower crane material; Improved the pole force-bearing situation, eliminated pole flexural deformation and stress, the impossible horizontal torsion of pole can lift by crane heavier object; The manufacturing cost and the overall weight of pole have been reduced.
The pole of above-mentioned two kinds of forms all can not possess the dual suspension as present patent application, the structure of two rocking arms.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of safe and reliable and have 360 ° of rotations of the two rocking arms of backguy pole in the inner suspension of inner suspension, two rocker structures.
The present invention solves its technical problem and is achieved through the following technical solutions:
360 ° of rotations of the two rocking arms of backguy pole comprises principal post, rocking arm, lifting pulley system, rocking arm pulley system in a kind of inner suspension, and the lower end of principal post is the suspension base, is fixed with the pocket rope on the suspension base, is fixed with stay cord on principal post, it is characterized in that:
(1) adopts turntable bearing coaxial 360 ° of rotations mutually between coaxial installation one mast on the principal post top, this mast and main shaft;
(2) be hinged with rocking arm in the mast bottom by the left and right mirror image symmetry of rocking arm free bearing, the two ends downside of each rocking arm all is equipped with the lifting pulley system;
(3) in the upper end of mast pulley base is installed, all be symmetrically installed with a rocking arm pulley on the distolateral top of each rocking arm, this rocking arm pulley and the rocking arm idle pulley of installing in mirror image symmetry on the pulley base, the guide wheel of in principal post, installing, the common rocking arm pulley system of forming of rocking arm fluctuating rope.
And, described lifting pulley system by lifting rope, play Hanging roller and the lifting driven pulley constitutes, play the two ends downside that Hanging roller and follow-up pulley are installed in each rocking arm, all lift weight at the lifting end of lifting rope.
Advantage of the present invention and beneficial effect are:
1, this pole has adopted the anti-turntable bearing of axially shearing, and makes the bilateral rocking arm to rotate on 360 ° of planes, thereby has enlarged the scope of lifting by crane the thing assembling, has solved because tower spare cooperates difficulty with suspension centre problem is organized in the landform restriction in advance.
2, the bilateral rocking arm of this pole can be according to instructions for use to the elevation angle adjustment that rises and falls, and by the rocking arm rope control that rises and falls, not only can realize can also realizing the bilateral operation to by the adjustment of lifting thing to centre distance, has improved operating efficiency.
3, scientific structure of the present invention, reasonable in design, to install reliably, operate steadily, the lifting scopes of 360 ° of rotations of the two rocking arms of backguy pole are bigger in the inner suspension, the operating efficiency height is applicable to that the one-sided lifting or the bilateral of UHV transmission line angle steel high tower or cast tower lifts by crane simultaneously.
