Abstract
A construction technology for hoisting and installing the coal bunker composed of several segments made of steel includes such steps as arranging two parallel cantilever tracks under a steel beam, laying down a track on the ground, hanging an electric pulley-type lifter to each cantilever track, manufacturing each segment of coal bunker, using a cart to transport it along the ground track to the installation position, lifting said segments one by one while welding, and installing the base of coal bunker.
Description
Technical field
The present invention relates to a kind of construction technology of hoisting steel made coal hopper on-site.
Background technology
Steel coal hopper is the device of thermal powerplant indispensability, and it is shaped as: top is that cylindrical silo bottom is the combination of conical silo.Steel coal hopper normally is installed in the C-D axle of power plant's deoxygenation bunker bay, traditional construction method of installation is to adopt crane lifting, because steel coal hopper height height, weight is big, crane often can not the Integratively hoisted in position, so generally be lifting ability according to hanging device, the steel coal hopper merogenesis is manufactured, treat that the factory building civil engineering construction is when be fit to installing the height layer of steel coal hopper, by crane the steel coal hopper of merogenesis is lifted successively and to overlay corresponding position and do working fastening, after the C-D axle framework for the treatment of the deoxygenation bunker bay binds, with manually with the steel coal hopper of merogenesis from the top down by the joint butt joint, weld in place.This construction method of installation stops the construction of agent structure and must will influence the scaffold complete removal in steel coal hopper hoisting passage and district in place when needing factory building civil engineering construction to the height layer that is fit to the installation steel coal hopper, so not only can cause the delay of civil engineering worker duration, and lifting the time needs two-shipper to lift, to guarantee the vertical lifting of member, according to each power plant's construction experience, under situation about not being affected by other factors, only Diao Zhuan duration the shortest is 35 days, and is long in time limit, cost is high.
Summary of the invention
The purpose of this invention is to provide a kind of installation duration short, cost is low, and is simple and easy to do, the construction technology of the hoisting steel made coal hopper on-site that the construction of factory building civil engineering is had no effect.
Construction technology of the present invention is as follows:
The steel roof joist lower edge that the factory building of steel coal hopper is installed in desire is provided with two parallel cantilever tracks, hangs an electric block on every track; Lay a secondary carriage walking track on the ground below the cantilever track, being provided with one on the carriage walking track can be along the track cross level travelling car; The steel coal hopper merogenesis is manufactured,, respectively each section is transported under the factory building according to the erection procedure of determining in the arrangement and method for construction by Pallet Truck, electric block along the cantilever orbital motion outside factory building, the steel coal hopper merogenesis is sling, vertical-lift, and in factory building, move, but steel coal hopper is placed on the dolly of parallel motion, dolly is by the installation site of winch running under power to steel coal hopper, by mounted jack in advance coal bunker is hung dolly, dolly withdraws from, and transfers jack steel coal hopper is placed into the installation site; Its sequence of erection is: earlier that a nethermost joint steel coal hopper is in place, and as far as possible to transferring, its top is installed can enough spaces, installs the 1st then and saves in last layer factory building ring beam, after the firm welding, carry out again the 2nd the joint, the 3rd the joint ..., the 2nd joint reciprocal installation, in installation process, behind the whole full welds of all weld seams, mention a nethermost joint with chain block again, dock, weld with a joint on it, carry out the installation of steel coal hopper seat at last.
Advantage of the present invention is: construction technology is simple and easy to do, and the installation duration is short, cost is low, and the construction of factory building civil engineering is had no effect.
Description of drawings
Fig. 1 is an installation scheme drawing of the present invention; Fig. 2 is the steel coal hopper vertical-lift scheme drawing of the K of Fig. 1 to amplification; Fig. 3 is the nethermost joint of a steel coal hopper scheme drawing in place.
The specific embodiment
Embodiment:
Present embodiment is at the newly-built 2 * 300MW unit of thermal powerplant, a specific embodiments of supporting steel coal hopper.With reference to accompanying drawing, steel roof joist lower edge at 22 meters layers of power plant's deoxygenation bunker bay C-D axle adopts track to fix two parallel cantilever tracks of being made by the 32# I-beam section 4 with girder steel lifting-point device 3, the cantilever of cantilever track 4 stretches out outside the factory building, and adopting drag-line 2 and upper strata factory building to fix, lifting altitude of suspension is 10 tons of electric blocks 1 of 30 meters on every track 4; Lay a secondary carriage walking track 6 on the ground below the cantilever track 4, being provided with one on carriage walking track 6 can be along track 6 parallel motion dolly 5; 47 tons of steel coal hopper 7 substances, making 5 periods of time-divisions manufactures respectively, by Pallet Truck according to the erection procedure of determining in the arrangement and method for construction, respectively each section is transported under the factory building, electric block 1 runs to outside the factory building along cantilever track 4, steel coal hopper 7 merogenesis are sling, vertical-lift is to 22 meters layers of the deoxygenation bunker bay C-D of power plant axle, electric block 1 moves in factory building, but steel coal hopper 7 is placed on the dolly 5 of parallel motion, dolly 5 is by the installation site of winch running under power to steel coal hopper, by mounted jack 8 in advance steel coal hopper 7 hung dolly 5, dolly 5 withdraws from, and transfers jack 8 steel coal hopper 7 is placed into the installation site; Its sequence of erection is: earlier that the 5th joint steel coal hopper is in place, and as far as possible to transferring, its top is installed can enough spaces, installs the 1st then and saves in last layer factory building ring beam, after the firm welding, carry out the installation of the 2nd joint, the 3rd joint, the 4th joint again, in installation process, behind the whole full welds of all weld seams, mention the 5th joint with chain block again, dock, weld with the 4th joint, carry out the installation of steel coal hopper seat at last.
Construction technology of the present invention and other main constructions construction mutually noninterfere, parallel line production do not take the main construction period, have accelerated construction speed greatly.
