Abstract

The invention relates to an internal-suspension internal-wire-drawing double-rocker 360-degree rotating pole which comprises a main post, rockers, lifting pulley systems and a rocker pulley system, wherein the top end of the main post is coaxially provided with a gin pole, and the gin pole and a main shaft can mutually and coaxially rotate 360 degrees by using a turntable bearing; the lower part of the gin pole is provided with the rockers in a left-right mirror symmetry mode through rocker hinged supports; the lower sides of both ends of each rocker are respectively provided with a lifting pulley system; the upper end of the gin pole is provided with a pulley seat; the upper part of the end side of each rocker is symmetrically provided with a rocker pulley; and the rocker pulleys, rocker idlers installed on the pulley seat in a mirror symmetry mode, guide pulleys installed in the main post, and rocker rising ropes constitute the rocker pulley system. 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

[0001] The invention belongs to the field of electric power, and relates to a holding pole used for assembling iron towers in the construction of UHV transmission lines, in particular to a 360° rotating holding pole with inner suspension and inner cable double rocker arms. Background technique

[0002] At present, UHV tower assembly methods are different at home and abroad. More than 50 years of history in the power transmission and transformation industry and the accumulation and precipitation of construction experience have made the tower assembly methods of each unit different, but in general it is nothing more than There are several types of holding poles, such as inner suspension type of inner cable, inner suspension type of outer cable, outer suspension type of outer cable, through sky type, through sky rocker type, inner suspension and outer cable rocker type and rocker rotating type. On the basis of several holding poles, each unit will improve and evolve ...

Embodiment Construction

[0020] The present invention will be described in further detail below through specific examples. The following examples are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by this.

[0021] An inner suspension and inner cable double rocker arm 360° rotating holding pole, including a main column 18, a rocker arm 8, a lifting pulley system, a rocker arm pulley system, and an axial shear-resistant turntable bearing 7. The lower end of the main column is a suspension base 19. Four ropes 17 are fixed on the suspension base, and four ropes 13 are fixed on the upper part of the main column. The ropes and ropes are fixed on the assembly tower.

[0022] A mast 4 is coaxially installed on the top of the main column. The mast and the main shaft are rotated coaxially with 360° with a turntable bearing. A pulley seat 1 is installed at the upper end of the mast; the lower part of the mast is mirrored on the left and right through the rock...
