Dig out ground buried via hole the most on the ground, vertical buried set is set in ground buried via hole and fixes.
C. by speciality axle horizontal positioned, it is inserted in boss at speciality axle axle head, at speciality axle, boss
The welding position of both, selects several position and uses argon arc welding weldering to carry out pre-welding, making axle head
Flange pre-fixes with speciality axle.
D. being vertically arranged in a frame by a base bearing, the outer ring of this base bearing is fixed with frame, this main shaft
The inner ring height held is higher than outer ring height, makes the axis of base bearing and the dead in line of buried set, uses
The speciality axle pre-fixed is sling together with boss by boom hoisting, makes speciality axle through main shaft
The inner ring that holds also stretches in buried set, and boss frame is on base bearing inner ring, by speciality axle and master
The inner ring of bearing is fastened to each other.
E. utilize machine power to make speciality axle along own axis, meanwhile, utilize artificial or weldering
The equipment of connecing is subjected to, and welding electrode is in same position, speciality axle, boss all the time
After rotating some circles together, welding completes.
In step a, offering of bevel for welding groove can increase the firm degree of welding, improves weldquality.
In step b, buried set can be big steel pipe, and its length is wanted enough, it is ensured that speciality axle lower end is the lowest
In in underground pipe lower end.
In step c, pre-welding can weld several point, it is also possible to directly welds last layer, two-layer, with speciality
Axle can substantially stationary be as the criterion with boss.
In step d, boom hoisting can be any conventional boom hoistings such as driving, crane.
After completing step e, if desired also weld at the boss back side, can be by speciality axle, axle head
Flange is inverted, and primitive axis end flanges upper surface is affixed on ground or rotatable rotary table, then uses aforesaid weldering
The method that connects (notes good for the bevel for welding slot welding at the back side: if welding herein, then during welding, boom hoisting should
All the time speciality axle is hung, with overturning-preventing).
Embodiment 2: the basic structure of the present embodiment and embodiment substantially with embodiment 1, its difference
Being, as shown in Fig. 4, Fig. 5, Fig. 6, described buried set includes overlapping body, bottom sealing plate 18, described
Set body, bottom sealing plate surround one and enter axle inner chamber, described frame is provided with filler pipe 19, going out of filler pipe
Water end (W.E.) passes to into axle inner chamber.Can pour water to entering in axle inner chamber, so that speciality axle major part is in water
In, by buoyancy, thus reduce and join the stiction between shaft sleeve and base bearing, and alleviate sleeve
Power suffered by crossbearer edge, moreover it is possible to abatement speciality axle stage casing, the vibrations of hypomere, improves the auxiliary to speciality axle
Support effect.
It is provided with support floatoblast 20 in described set body, with described set, is provided with floatoblast baffle plate 21, described
Being provided with axis hole in the middle part of floatoblast baffle plate, described floatoblast baffle plate outward flange is fixed with set body inwall, described
Support floatoblast to be between floatoblast baffle plate and bottom sealing plate.
Speciality axle is the longest due to length, and it is when being vertically arranged, and is it is difficult to ensure that high perpendicularity,
A little vertical of top, will result in bottom skew theoretical centerline a lot, and speciality axle self
Stage casing has at one or to have a slight curvature also be unescapable situation at a few place.Under this premise, speciality axle exists
Under rotation status, its bottom face is also impossible to level very.Now, support is provided to speciality axle bottom
Will be in view of situations such as skew, vibrations, common planar support not only sets up difficulty, and (precision is wanted
Ask high), and effect the most limited (speciality axle bottom face is uneven, actual for point cantact support), and by
In buried set buried enter ground, bottom support need preset, at this time to amount of calculation and support member required precision
The highest, otherwise, as long as after speciality axle stretches into buried set, the most very likely occur support not in place or
The situation that supporting surface (locally) is too high, causes supporting and lost efficacy or speciality axle is applied excessive upper top power,
Thus cause speciality axle rotation process unstable.In the present embodiment, it is provided that support floatoblast, floatoblast quilt is supported
After under speciality axial compression, shape can carry out adaptive change, and laminating degree is good, and can dynamically regulate, from
And in the rotation process of speciality axle, the support that the moment keeps up, and can effective vibration-inhibition, also
Do not have and support the situations such as not in place.
Described support floatoblast is provided with inflation inlet, and inflation inlet and support are passed through in one end of a loading line 22
Floatoblast connects, and the other end of described loading line connects an inflator pump 23, and machine is located at by described inflator pump
On frame.When the support force deficiency needed, can improve, by the way of inflation, the elasticity supporting floatoblast
Restoring force, thus increase the support force to speciality axle, and, the change of this force, will not be to speciality
Axle and other structure damage, and support the deformability of floatoblast self and passively regulate adaptability the most still
So can be maintained.
Described loading line is provided with bye-pass 24, and described bye-pass one end is connected with loading line,
The other end is provided with top sealing plate 25, is provided with sliding valve core 26 in described bye-pass, and described sliding valve core can
In bye-pass slide and and bye-pass inwall between sealed to each other, described top sealing plate is provided with switch and pushes away
Lever 27, described contact slide spool upper end, switch catch bar lower end, top is stretched out in switch catch bar upper end
Shrouding is outer and just switch to inflator pump, is provided with two protection springs 28 in described bye-pass, described
Protection spring one end connects top sealing plate, and the protection spring other end connects sliding valve core, and described switch promotes
Bar is slidably connected with top sealing plate.Carry out pneumatic compression to supporting floatoblast, support force can be improved, promote and prop up
Support effect, alleviate and join shaft sleeve, the support pressure of sleeve crossbearer edge.After the blowing pressure is relatively big, now
If continuing inflation, just having and supporting the risk that floatoblast breakage is fried.In the present embodiment, when the blowing pressure is less or
Not up to during certain value, the gas in loading line pushes sliding valve core, and sliding valve core press against protection spring
Making it shrink certain distance, switch catch bar rises a segment distance, but can't touch opening of inflator pump
Close；When the blowing pressure is relatively big, after reaching certain value, switch catch bar rises to touch opening of inflator pump
Closing, inflator pump closes down, and inflation is automatically stopped, thus realizes supporting floatoblast and other buried structure
Protection, when needs are exitted, directly separates loading line with inflator pump.
