Method and equipment for hanging iron tower

Abstract

The invention provides a hoisting method for a turricula and the device thereof. A lifting pedestal and a lazy arm pedestal are arranged on a lifting working platform. A rotary lazy arm is hinged with the lazy arm pedestal. A lifting rope and a lifting winch form a lifting mechanism through a crown block and the rotary lazy arm of the lazy arm pedestal. A pulling rope and a pulling winch form a pulling mechanism through the crown block of the rotary lazy arm. A hoisting rope and a hoisting winch form a hoisting mechanism through a hoisting block of the rotary lazy arm and a block on the lazy arm pedestal. The other end of the hoisting rope is provided with a lifting hook. The invention uses the lifting winch to lift the lazy arm in the hoisting mechanism and simultaneously lift the turricula and prick as well as release the hoisting winch and the pulling winch to arrange the turricula on a preassemble tower seat, mount and construct thereof to finish the hoisting of the turricula. The invention solves the problems that the upright stanchion tower of a crane group in existing hoisting construction method and device for turricula is restricted by conditions and has the disadvantages of higher tower composing cost, needing men for measuring instruments, a plurality of anchor block pits and operating personnel as well as low efficiency, etc.

Description

Technical field: [0001] The invention relates to a hoisting method of an iron tower, and meanwhile provides corresponding hoisting equipment, which belongs to the technical field of hoisting machinery equipment. Background technique [0002] At present, there are two methods of erecting pole towers for power lines: crane and pole holding. The use of cranes to lift the whole base of the tower needs to be carried out where traffic conditions permit. According to the specifications of the tower, a crane of 25 to 150 tons is generally used. The construction of the line is often located in a remote place. It is generally difficult to rent a large crane in the local area. The crane set up the tower It has high requirements on road conditions, and is only suitable for construction in plain areas with high ground strength, and the cost of erecting towers is relatively high; the use of current pole-holding towers is not restricted by roads and terrain, but requires a lot of steel rop...
