Description

A kind of lifting installation method with umbellate form blast cap Large Diameter Pipeline blow-down pipe
Technical field
The present invention relates to a kind of methods of lifting Large Diameter Pipeline blow-down pipe and umbellate form blast cap.
Background technology
In gas pumping equipment of pumping station installing engineering, the specification of Large Diameter Pipeline blow-down pipe is typically that diameter phi is more than or equal to The steel pipe of 800mm installs umbellate form blast cap at the top of blow-down pipe.Made of the steel plate that umbellate form blast cap is rolls, size is big, structure It is soft.Umbellate form blast cap, need to be fixed at the top of blow-down pipe by previous construction before lifting by crane blow-down pipe.Then recycle crane that will be vented Pipe lifts installation, and previous hoisting method is to weld lifting lug directly on blow-down pipe and hang up properly steel wire rope and buckle to hang.But such umbrella Type blast cap easily deforms after being squeezed by steel wire rope Le, needs to remake blast cap after damage, extends installing engineering progress, increase work Journey expense.
Invention content
Purpose of the present invention is to overcome the shortcomings of above-mentioned prior art, providing one kind can prevent round umbellate form blast cap in lifting process It is middle to deform, to avoid the lifting installation method with umbellate form blast cap Large Diameter Pipeline blow-down pipe done over again.
The method of the present invention is:
(1)According to the blow-down pipe and umbellate form blast cap appearance and size lifted, a set of lifting apparatus is made;It includes balance to lift by crane apparatus Pipe, connection lifting lug and steel wire rope;It includes two balance drop tee Ts and two emptying drop tee Ts to connect lifting lug;Balance pipe is using seamless Steel pipe, length will be longer than the diameter of suspended object part cowl, if seamless steel pipe insufficient strength, in place can add Reinforcing rib is to ensure its intensity.
(2)Two balance drop tee Ts are attached separately to balance pipe both ends;Two emptying drop tee Ts are attached separately to blow-down pipe two Side;Steel wire rope is divided into upper and lower two sections;There are two hypomere steel wire ropes, length is identical, is connected to emptying drop tee T and homonymy Between balance drop tee T;Epimere steel wire rope is connected between two balance drop tee Ts;The length of epimere steel wire rope is more than balance pipe Length;
(3)Selection balance length of tube and emptying drop tee T installation site and hypomere rope capacity so that emptying drop tee T with Hypomere steel wire rope between homonymy balance drop tee T stretches tension, is stayed between hypomere steel wire rope and suspended object part cowl edge There is certain interval, to prevent suspended object part cowl from deforming or breaking lifting steel wire rope;
To prevent steel wire rope to be broken at lifting lug, steel wire rope protection ring and load clamp are had additional at lifting lug.Load clamp is One U-shaped part is attached separately to balance drop tee T by fixed pin shaft and is vented on drop tee T;Steel wire rope protection ring is water-drop-shaped Shape is sleeved on load clamp;Steel wire rope both ends are connected to by steel wire rope protection ring on load clamp;Connect the thick steel of lifting lug selection Plate makes, and effect is to connect upper and lower hoisting wirerope, it is desirable that has comparable intensity.
(4)Epimere steel wire rope midpoint is triggered with crane hook, crane hook is slightly lifted, upper and lower two sections of steel wire ropes It all tightens, after suspended object part balance, draws high crane hook again, suspended object part is sling and is put to required position Installation is fixed.
The method of the present invention suitable for gas pumping equipment of pumping station installing engineering to Large Diameter Pipeline(In general, caliber is equal to Or it is more than 800mm)It is vented the lifting installation of steel pipe.Advantage be it is possible to prevente effectively from deformation of umbellate form blast cap during lifting, Artificial material is saved, efficiency is improved, overcomes original common hoisting method to easily cause the deformation of umbellate form blast cap, in turn results in wind Cap do over again again fabrication and installation, take a lot of work material a series of problems, such as.

In figure:1, crane hook, 2, epimere steel wire rope, 3, balance pipe, 4, balance drop tee T, 5, cowl, 6, under Section steel wire rope, 7, blow-down pipe, 8, emptying drop tee T, 9, steel wire rope protection ring, 10, load clamp.
Specific implementation mode
Singapore dollar company of Yang Mei groups gas pumping pumping plant installs gas blow-down pipe, and the specification of installed gas blow-down pipe is: φ1020mm(Diameter)×22mm(Skin depth), it is 18 meters long, it is vertically-mounted, umbellate form blast cap is installed at the top of blow-down pipe.Umbellate form blast cap It is to be rolled using the steel plate of 6mm thickness, a diameter of 2000mm of blast cap.Using the method for the present invention lifting gas blow-down pipe once at Any deformation does not occur for work(, umbellate form blast cap, efficiently completes lifting task.Installation process is lifted by crane in specific allocation and transportation:
(1)Make a set of lifting apparatus, including balance pipe 3, connection lifting lug and steel wire rope;Connection lifting lug is hung including two balance pipes Ear 4 and two emptying drop tee Ts 8;3 length of balance pipe is longer than suspended object part cowl diameter;
(2)Two balance drop tee Ts 4 are attached separately to 3 both ends of balance pipe;Two emptying drop tee Ts 8 are attached separately to 7 liang of blow-down pipe Side;Steel wire rope is divided into upper and lower two sections;There are two hypomere steel wire ropes 6, and length is identical, is connected to emptying drop tee T 8 and homonymy Balance drop tee T 4 between;Epimere steel wire rope 2 is connected between two balance drop tee Ts 4;
(3)Being vented the installation site of drop tee T 8 will determine according to 3 length of balance pipe and the diameter calculation of cowl, under guarantee There are certain interval between section steel wire rope 6 and 5 edge of suspended object part cowl, 6 angle with horizontal plane of hypomere steel wire rope is not small In 60 °.Cowl 5 and blow-down pipe 7 are connected and fixed by the modes such as welding, riveting.
Steel wire rope protection ring 9 and load clamp 10 are had additional at lifting lug.Load clamp 10 is U-shaped part, passes through fixed pin Axis is attached separately to balance drop tee T 4 and is vented on drop tee T 8;Steel wire rope protection ring 9 is drop shape, is sleeved on load clamp 10 On;Steel wire rope both ends are connected to by steel wire rope protection ring 9 on load clamp 10;Lifting lug selection steel plate is connected to make.Hypomere It is connected by load clamp 10 between steel wire rope 6 and emptying drop tee T 8, between hypomere steel wire rope 6 and balance drop tee T 4, on It is connected by load clamp 10 between section steel wire rope 2 and balance pipe connection lifting lug 4.
(4)2 midpoint of epimere steel wire rope is triggered with crane hook 1, crane hook 1 is slightly lifted, upper and lower two sections of steel wires Rope 2,6 is all tightened, and after suspended object part balance, draws high crane hook 1 again, suspended object part is sling and is put to required It installs and fixes at position.
