Abstract

The invention provides a single-action arm ground lifting pole with a flowing water counterweight system, which comprises a lifting pole foundation, a jacking sleeve frame, a tower body, a rotary assembly and a lifting pole head that are arranged sequentially from the bottom up, wherein the rotary assembly is provided with a lifting arm and a balance arm. The lifting pole is characterized in that the rotary assembly and the balance arm are provided with the flowing water counterweight system; the flowing water counterweight system comprises hydraulic pushers, small water tanks and a counterweight water tank; the hydraulic pushers and the small water tanks are arranged on the rotary assembly; the counterweight water tank is arranged at the tail of the balance arm; and the small water tanks are connected with the counterweight water tank via water pipes. Compared with the prior art, the stress condition of the single-action arm ground lifting pole with the flowing water counterweight system can be improved, the lifting capacity of the lifting pole is improved, or the sectional dimension and weight of a pole body are decreased under the same lifting capacity, and the single-action arm ground lifting pole better meets erection requirements of an ultra-high voltage transmission line iron tower.

Description

technical field

[0001] The invention relates to a single boom landing pole, in particular to a single boom landing pole with a flowing water counterweight system. Background technique

[0002] The holding pole is an important special lifting equipment in the construction of the tower of the transmission line project. With the increase of the voltage level of the transmission line, the weight and height of the transmission tower continue to increase, and the difficulty of the construction of the tower increases accordingly. The construction of the conventional lifting equipment is difficult and the work efficiency is low. Therefore, the design and optimization of large-scale landing poles is an important research content of construction design.

[0003] The single boom landing pole SXD50 is based on the construction tower crane, aiming at the characteristics and requirements of the construction of the UHV transmission line tower, drawing on the advantages of the double flat ...
