Embodiment
Pipeline construction has directly to lift long tube at the top of piping shaft and is sent into well in the prior art, but required lifting is set
Standby big, implementation cost is very high.And when pipe well internal riser is installed such as tower crane has been removed, then transport and manage using plug-in elevator, it is high
Building is built typically per floor FFL between 3-4.5 rice, including basement, and elevator size is corresponding to per layer height, because of elevator
Size limitation needs to cut off homogeneous tube.Existing pipeline be generally it is six meters long, pipe cutting per segment length be 3 meters, it is necessary to by this
A little pipelines deliver to each floor respectively could prepare to weld, and transport amount is big.Because the duct section after cutting is more, Welder in well
Make quite heavy, and space is small in pipe well, pipeline is more, welds narrow conduit welding under space and welding dead angle be present.
The present invention is intended to provide a kind of reduce transport, reduce weld job, the scheme of complete solder.There is provided for this present invention
Large diameter pipe pipe fitting method in a kind of pipe well, its step are：
1) first pipeline is transported into pipe well from one layer of ground (the also referred to as first floor) oblique traction, is erected at pipe well bottom.
2) second pipeline is transported into pipe well from one layer of ground oblique traction, second pipe diameter overlays to bore
On a piece pipeline.
3) from pipe well entrance side setting welding gun, welding gun align with tube seam a bit, rotating pipe carries out pipeline butt weldering
Connect.
4) pipeline is transported into pipe well successively by above-mentioned steps, and bore counterpart footpath stacks and is sitting on a pipeline, rotation
Pipeline simultaneously carries out synchronous welding.
5) finally, the pipeline for welding completion is done fixed in well.
The mentality of designing of this method is：By whole pipelines successively from the first floor, i.e. pipe well is transported on one layer of ground, with small-sized lifting
Be lifted into relevant position after equipment oblique traction to pipe well, because oblique space is big, can for 6 meters of homogeneous tube pipeline by,
Pipeline hop count is reduced, reduces the workload of welding；And rifle is welded in welding can not cause to weld dead angle around management movement, we
Devising corresponding construction makes pipeline rotate the position for deacclimatizing welding gun, makes interface week circle complete solder.
To realize the above method, the present invention provides large-diameter pipeline installation equipment in a kind of pipe well, includes and be installed on pipe
Raising cord 3 on the rotating base 4 of bottom, the electric lifting device 2 being installed at the top of pipe well and electric lifting device, institute
State rotating base 4 and be provided with roller groove 42 including bottom plate 41, bottom plate 41, the roller group of radial arrangement is installed in roller groove 42
43；Cover plate 44 is placed with roller group 43, with being connected with torsion gear in the affixed integral instrumentation tubes 46 of cover plate 44, instrumentation tubes 46
45；The side of 41 upper idler wheel channel of bottom plate 42 is provided with motor 47, and the top of motor 47 is provided with travelling gear 48, and travelling gear 48 is with reversing tooth
The engagement of wheel 45.
As the improvement of the said equipment, the rotating ring 5 being sleeved in the middle part of pipeline is also add, the rotating ring 5 includes set
Pipe 51, the inner side of sleeve pipe 51 are provided with axially arranged some rollers 52.
The specifically used method of this equipment is：
1) rotating base is installed two layers located underground of pipe well bottom, and debugs and finish, installed at the top of pipe well electronic
Raising cord on lifting device and electric lifting device.
2) pipe well is transported from the first floor with first pipeline of raising cord oblique traction, is sitting in the instrumentation tubes of rotating base and welds
Connect firmly.
3) second pipeline is transported into pipe well from the first floor, second pipe diameter is overlayed to bore on first pipeline.
4) from pipe well entrance side setting welding gun, welding gun align with tube seam a bit, rotating pipe carries out pipeline butt weldering
Connect.
5) untill carrying out the top layer for being soldered to building of other pipelines by above-mentioned 2 to 4 step flow.
6) pipeline for welding completion is done fixed in well.
Because pipe well is not only high but also long in high building, when pipeline welding to high level, can with installation rotating ring temporarily on pipeline, one
The stable pipeline of aspect, on the one hand reduces rotation friction.Rotating ring is installed on pipeline every three layers, until the pipeline all welds
Removed after mouth welding.
Because the duct length in pipe well is typically up to more than 30m, ensure that the perpendicularity of pipeline must be by design requirement pipe
Road support is installed in place.
This equipment is relatively specific for tower crane and removed, after pipe well has bound.Electric lifting device 2 is installed on pipe well roof
Guide rail 1.The track 1 is made up of I-steel.Track 1 can be directly anchored on pipe well roof, and one end is fixed on pipe well side wall
On, the curved other end that turn 90 degrees stretches out pipe well side port.Such structure can make the Hoisting Position of lifting device cover pipe well comprehensively.
After this method, pipeline directly can enter in pipe well from the first floor, and the problem of avoiding Pipe Cutting, it is unnecessary to reduce
Welding job amount, improve operating efficiency.Welding dead angle is eliminated by the method for rotating pipe simultaneously, improves welding speed
Degree and quality.
