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:
The present invention relates to a kind of hanging method of iron tower, corresponding hanging device also is provided simultaneously, belong to the lifting equipment technical field.
Background technology
At present, electric power circuit group vertical rod tower has crane and two kinds of methods of pole.Adopt the crane integral basis to hang the vertical rod tower, need be in the place that transportation condition allows, specification according to shaft tower, 25～150 tons of cranes of general use, line construction is often remote, and large-scale crane generally is difficult in the locality rent, and crane group vertical rod tower is had relatively high expectations to road conditions, only be adapted at the higher place construction of region of no relief ground intensity, group vertical rod tower expense is higher; Adopt existing pole group vertical rod tower not limited by road and landform, but need Work tools such as a large amount of steel cable, the rope made of hemp, coaster, cucurbit and earth anchor, pole, the every at least base of split tower erection will dig 4 shakedown holes, with the upright iron tower of integral body group is example, with upright general 20～22 people that need of pole group, needs production time 16 hours, also not including ground prepares and the ground group tower time, the group vertical rod tower time is longer, needs more operating personnel, and the construction safety dangerous point is many.
Summary of the invention
The invention provides a kind of hanging method of iron tower, its objective is that will solve existing iron tower construction method for hanging crane group vertical rod tower is subjected to condition restriction, the higher and existing pole group of group tower expense vertical rod tower needs the people to measure problems such as Work tool, ground anchor pit and operating personnel are many, efficient is low.
Technical solution of the present invention is as follows:
On the lifting work platform, be respectively equipped with derricking gear, hoisting mechanism and trailer coupling, iron tower is fixed on arm two ends in the hoisting mechanism, by derricking gear with the arm pull-up, iron tower is promoted vertically, the twisted rope that discharges derricking gear and trailer coupling is placed on iron tower on the prepackage tower seat, the lifting of iron tower is finished in installation.
Concrete hoisting equipment structure is as follows:
Lifting pedestal and boom base are set on the lifting work platform, each pedestal be provided with fixed pulley, one end of rotary suspension arm and boom base hinge-coupled, lifting rope is fixed on the front end of rotary suspension arm, and constitutes derricking gear by the fixed pulley of boom base with the lifting capstan winch; One end of hauling rope constitutes trailer coupling through the fixed pulley and the towing capstan on the lifting platform at rotary suspension arm middle part, and the other end is provided with suspension hook and the bottom of iron tower can be fixed; The lifting rope constitutes hoisting mechanism through the fixed pulley and the lifting capstan winch on fixed pulley on the boom base and the lifting work platform on rotary suspension arm top, and the other end is provided with fishhook.
Described lifting work platform bottom is provided with the rotation of rotating mechanism may command platform.
When hanging device of the present invention uses,, select lifting work platform permanent seat to be connected the jig size, prepare basic discrepancy in elevation chock with the basis according to the key dimension and the site contour of prepackage column foot; Open and height according to the iron tower root, select arm and rise and fall pole joint number and size; According to iron tower weight, size and complete equipment parameter, check the lifting condition.
The on-the-spot layout: the basis and the lifting work platform permanent seat that connect prepackage iron tower base; The lifting work platform is installed on lifting work platform permanent seat; Weight-lifting equipments such as lifting pedestal, boom base, lifting capstan winch, lifting capstan winch, towing capstan are installed on the lifting work platform; Connect arm along the iron tower bottom to the tower head direction, state is lifted by crane on the ground of seeing Fig. 1 of putting of iron tower and rotary suspension arm; Hauling rope, lifting rope, rotary suspension arm are connected with iron tower; Tighten hauling rope and lifting rope, the lifting rope fixation side is trivial dead; Start the lifting capstan winch, the pull-up rotary suspension arm is checked the stressed and device situation of each by the lifting regulation; By the weight line, iron tower is winched to basic on a line of centers; Open the fixed pulley of iron tower bottom and rotary suspension arm, iron tower is vertically dropped down onto iron tower foundation, aim at holding-down bolt, iron tower lower margin side is gone in the holding-down bolt last anchor bolt; Unclamp lifting rope, put down the weight line, rotation lifting work platform is to the iron tower side; Start winch, put down the installation that rotary suspension arm is finished iron tower.
Advantage and progressive being that the present invention has with respect to prior art: be respectively equipped with derricking gear, hoisting mechanism and trailer coupling on the lifting work platform, by lifting by crane capstan winch with the arm pull-up in the hoisting mechanism, iron tower and the lifting of arm one, the iron tower lifting is holded up, discharging lifting capstan winch and towing capstan is placed on iron tower on the prepackage tower seat, the lifting of iron tower is finished in installation.The invention solves existing iron tower construction method for hanging, crane group vertical rod tower is subjected to condition restriction, the higher and existing pole group of group tower expense vertical rod tower needs the people to measure problems such as Work tool, ground anchor pit and operating personnel are many, efficient is low.Overcome in the crane lifting iron tower leg scrape and the wayward problem of swinging, must professional driver not cooperate in the lifting.Improve work efficiency, reduced power off time.Not limited by the road landform, need not excavate cat hole, ground, scope of work is little, reduces labour intensity, reduces construction costs, and the group column efficiency can improve more than 75%.
