The invention provides a movable tower crane for electric tower assembling. The movable tower crane for electric tower assembling comprises a movable chassis and a telescopic arm mechanism, wherein a crawler-type walking mechanism is arranged on the lower portion of the movable chassis, the telescopic arm mechanism comprises a plurality of layers of sleeve rods, and the outermost-layer rod body of the plurality of layers of sleeve rods is connected with the upper portion of the movable chassis through a parallelogram mechanism and a supporting oil cylinder; a rocker arm is connected to the top end of the innermost-layer rod body of the plurality of layers of sleeve rods; and a hoisting winch is arranged on the outermost-layer rod body, a hoisting steel wire rope is wound on the hoisting winch, and the end part of the hoisting steel wire rope bypasses a first pulley at the top of the rocker arm and is connected with a hoisting hook. The movable tower crane for electric tower assembling adopts modular design, is simple to assemble and manufacture, has mountain walking capacity, is convenient to operate in areas with complex terrains, occupies less space after a telescopic arm retreats, and is convenient to transport; and a supporting leg oil cylinder is arranged at the bottom of the telescopic arm, so that the stability of the telescopic arm in a construction process is ensured.
Description
technical field [0001] The invention relates to a tower crane, in particular to a mobile tower crane used for erecting electric towers. Background technique [0002] The transmission line project has many points and a wide area, and the labor investment in the construction is large, the research and development and investment of construction machinery are insufficient, and there is a lack of high-efficiency and specialized construction machinery. In recent years, a large number of excellent construction machinery manufacturing enterprises have emerged in China, which has promoted the improvement of construction mechanization level. For the construction industry of transmission line engineering iron tower assembly, it is urgent to apply efficient and professional construction machinery to carry out mechanized construction. The labor intensity of the operators is high, the efficiency is low, the construction period is long, the operation is highly dangerous, and some construc...
