Problems solved by technology

The traditional pole holding is far from being able to meet the construction and construction requirements of UHV lines.
[0003] The traditional double rocker arm swing pole can only meet the construction of iron towers with lower voltage levels, and it is difficult to meet the construction of UHV line iron towers; the traditional double rocker arm swing relies on manual rotation, and the construction of UHV line iron towers is limited by the site terrain. It is almost impossible to realize manual rotation; the traditional double rocker arm rotation holding pole structure has a single function and does not have various control functions

Embodiment Construction

[0025] Such as Figures 1 to 10 As shown, the double rocker arm electric control rotary pole of the present invention includes a main pole section 1 , a mast 2 , a rocker arm 3 and a pole holding operation platform 4 .

[0026] The main rod section 1 is vertically arranged, and it includes a combined lower base 11 , a hydraulic lifting frame 12 , a main column 13 , an anti-twist waist ring 14 and an electric rotary hinge seat 15 . Among them, in this embodiment, the main pole section adopts a 1-meter-square structure, and the 2-meter section is used. The main material and oblique material are all 16Mn, which can be connected to form rocker poles of different heights.

[0027] The combined lower base 11 is fixed on the bottom surface, and its periphery is evenly provided with a plurality of steering blocks 111, wherein the combined lower base 11 is connected and fixed with the external iron tower 5 through the steering blocks 111 equipped with steel wire ropes.

[0028] The hy...

Abstract

The invention relates to a double-rocker-arm electric control rotation derrick which comprises a vertically-arranged main rod section, a mast, a derrick operation platform and at least one pair of rocker arms. The main rod section comprises a combination type lower base, a hydraulic lifting support, a main column and an electric rotation hinge base. The electric rotation hinge base is controlled by the derrick operation platform to conduct rotation and comprises a supporting frame, a hinge base body, a rotation bearing fluted disc, a motor, a reduction box and a rotation bearing base; angle transducers are arranged on the root portions of the pair of rocker arms and provided with anti-abrasion rope structures to be hinged to a connecting arm of the electric rotation hinge base; the derrick operation platform comprises a control cabinet, a monitoring display screen, a speed controller and a display limitation alarm device. The double-rocker-arm electric control rotation derrick is simple and reasonable in structural design, easy and convenient to assemble and apply and capable of achieving integrated operation such as electric control, detection, monitoring and alarming, the construction safety and the construction reliability are improved, the assemblage construction requirements of extra-high voltage line iron towers can be met, and the labor efficiency can be improved.

Description

technical field [0001] The invention relates to the field of transmission line construction of electric power transmission and transformation projects, in particular to a double rocker arm electric control rotary holding pole. Background technique [0002] With the continuous development of national power construction, UHV transmission lines have been continuously constructed and operated. The traditional pole holding is far from being able to meet the construction and construction of UHV lines. [0003] The traditional double rocker arm swing pole can only meet the construction of iron towers with lower voltage levels, and it is difficult to meet the construction of UHV line iron towers; the traditional double rocker arm swing relies on manual rotation, and the construction of UHV line iron towers is limited by the site terrain. It is almost impossible to realize manual rotation; the traditional double rocker arm rotation holding pole structure has a single function and do...
