Specific embodiment
The utility model is described in detail in 1~4 specific embodiment with reference to the accompanying drawing:
The pedestal 3 and leading truck 4 of device noumenon are formed by I28b I-steel welding production.Pedestal 3 is rectangle plane steel framework
Frame is placed on workbench positioned at the lower part of whole device.Pedestal 3 is steady for increasing its vertical direction using expansion frame
It is qualitative.Leading truck 4 is square the three-dimensional steel-frame structure in section, is welded on 3 center of pedestal, inside uses I12.6 I-steel
Leading truck vertical bracing 7, to leading truck 4 carry out rigidity reinforcement.On the outside of 3 rectangular frame of pedestal, 4 left and right sides of leading truck,
The symmetrical triangle support frame 5 for laying I12.6 I-steel is used as diagonal brace, and pedestal 3 and leading truck 4 is integrally welded, guarantees to lead
To the rigidity and stability of frame 4 in vertical direction.It omits the every side of 4 horizontal cross-section I-steel square frame inside dimension of leading truck
Greater than 1 outer diameter of casing (5-10cm), and four right angles, up and down direction lay the leading truck of no less than 2 groups of I12.6 I-steel
Horizontal bracing 6 reinforces the structural stability of leading truck 4.Close to two water of upper/lower terminal in the middle part of four sides of leading truck 4
Prosposition is set, and is laid with two groups, each 4 32 essences bundle screw rod 2, symmetrically altogether to adjust the verticality of casing 1 Yu pedestal 3.
4 horizontal cross-section side length of leading truck is 150cm, a height of 300cm of square frame；The widened steel frame pedestal 3 in lower part is long
For the rectangle of 630cm × 208cm；Triangle support frame 5 lower part connection on the base 3, apart from leading truck 4 be 150cm at, it is right
Claim to lay diagonal brace on the side wall of leading truck 4, it is integrally welded.
When work, moving hanging basket is installed by 25T crane.Device noumenon is steadily sling with crane, is moved closer to
Stake holes is then placed on Pile Installation Platform.Positioning reinforcing is carried out to pedestal 3 using bolt, it is consolidated and is mounted on pile foundation
On operation platform.Confirm whether each component connection such as pedestal 3, leading truck 4, triangle support frame 5 is solid and reliable, is then protected
Cylinder 1 is hung.When casing 1 is hung, by two rows adjustment screw 2, verticality of the casing 1 relative to pedestal 3, casing 1 are adjusted
One section of every follow-up (about 2m), detects pile foundation pedestal 3 and the verticality of casing 1 when decentralization, and discovery deviation passes through tune in time
Whole screw rod 2 is adjusted, until casing 1 is perpendicular to pile foundation pedestal 3, and is transferred to predetermined position.
The tooling can be used as the temporary fastening device of casing spreading welding simultaneously.The locator under pile foundation construction casing
On above the casing that has descended, lift by crane spreading casing with crane, be slowly put into leading truck.Weld job face is placed on two as far as possible
Arrange the operation interval of adjustment screw, conducive to adjustment need to lengthen casing under good casing concentricity, it is correct to weld.
The above is the preferred embodiment of the utility model, not does limitation in any form to the utility model,
All contents without departing from technical solutions of the utility model, it is made by the above technical examples according to the technical essence of the present invention
The simple replacement of simple modification, equivalent variations and profile in any structure, belongs to the guarantor of technical solutions of the utility model
Protect range.
