Problems solved by technology

However, due to the large number of components and large structural size, the above-mentioned pole-holding equipment has problems such as unit weight and total weight, inconvenient transportation and use on the construction site, and high cost of purchase and transportation. The hanger control wind rope and the structure size of the existing flat arm pole or tower crane are too large to be transported to the tower position and cannot be used

Embodiment Construction

[0037] The following will be described in conjunction with the accompanying drawings and specific embodiments.

[0038] Picture 1-1 An overall example of a self-balancing AM pole is shown. see Figure 1-1 to Figure 3-2 , the main pole 1 is a circular tube type inner suspension pole, and the main pole is composed of multi-section lattice sections connected by bolts, as described in Chinese patent 200910058946.2. Booms 2 are symmetrically arranged on both sides of the upper and middle positions of the main pole 1 , and a claw arm assembly 101 is installed on the top of the main pole. Two pulleys are arranged on the top of the claw arm assembly 101 . A fixed block 901 is installed on the upper right side of the main pole 1, and the first amplitude modulation pulleys 902a and 902b are symmetrically installed on the main pole 1 below the fixed block 901; the boom 2 is hinged on the main pole, and the outer end of the boom 2 The second amplitude modulation block 903a, 903b is ins...

Abstract

The invention relates to a self-balancing amplitude modulation holding pole which comprises a main holding pole, a suspension arm, a first amplitude modulation pulley, a second amplitude modulation pulley, an amplitude modulation tackle, an amplitude modulation rope and a lifting rope, wherein the suspension arm, the first amplitude modulation pulley, the second amplitude modulation pulley, the amplitude modulation tackle and the amplitude modulation rope are symmetrically arranged relatively to the main holding pole; and the stress points of the lifting rope on the amplitude modulation holding pole are symmetrical relatively to the main holding pole. Compared with the prior art, the self-balancing amplitude modulation holding pole realizes self-balancing stress of weights arranged on the two sides relatively to the holding pole, and reduces the requirement on the strength of the main holding pole and the suspension arm, thus reducing the structural size and the weight of the main holding pole and the suspension arm on the whole, and being convenient in transportation, installation and disassembly, low in cost and beneficial to popularization and application.

Description

technical field [0001] The invention belongs to the technical field of electric power construction equipment, and in particular relates to a power transmission line tower construction device. Background technique [0002] With the construction of UHV, compared with ordinary 500kV line towers, UHV line towers are taller, larger, and heavier. The construction of iron towers is very difficult, especially the hoisting radius is large. Continue to use The traditional internal suspension pole group tower has low construction efficiency and high safety risks. In order to improve efficiency and safety, many construction units have successively developed double-flat arm poles (CN200920200519.9), double-flat arm base ground poles (CN200720085113.1), double-rocker poles (CN200920114311.5), tower Construction methods such as hoisting and grouping towers by type cranes. However, due to the large number of components and large structural size, the above-mentioned pole-holding equipment ...
