Precision can also be equipped with laser guidance device, obliquity sensor.In order to increase stability, pedestal can also be set.
Upper and lower clamp assemblies main body is a platform member in this embodiment, has in platform hook and steel column is allowed to wear
The first, second through-hole crossed, and for the first, second clamping element of clamp or release steel column, clamping element can use liquid
Clamping device is pressed, set-up mode, which can be, to be directly anchored in upper and lower two platform members,
Adjusting component includes multiple straight-line motion mechanisms and rotating mechanism, straight-line motion mechanism can be hydraulic cylinder,
Electric cylinder, electric pushrod or ball-screw etc..Rotating mechanism can be using universal spherical joint, cross universal hinge or hinge etc..It has
The set-up mode of body is, upper and lower clamp assemblies pass through respectively to be rotatably connected in the push rod of the oil cylinder of hydraulic cylinder and solid
On fixed end, it is hydraulic have sympathetic clamp assemblies or lower clamp assemblies can be pushed to move in a straight line.Electric cylinder, electric pushrod are set
Set that mode is similar, the set-up mode of ball-screw is that upper and lower clamp assemblies are separately positioned on the traveling nut on screw rod and screw rod
On, it moves along a straight line.The movable both ends of universal spherical joint, cross universal hinge or hinge are separately positioned on corresponding upper and lower clamping
On component and straight-line motion mechanism, there are two the freedom degrees relatively rotated for two components that rotating device allows to connect.Straight line fortune
Motivation structure is connect by rotating mechanism with upper and lower clamp assemblies, and upper and lower clamp assemblies are in the movement side where straight-line motion mechanism

To the adjustment of all angles, and it is further, it can be set to 2,4,5 are even more.
It is constructed using the above-mentioned vertical underthrust constructing device of steel column high-precision, Specific construction principle are as follows: using super
Retarded concrete construction lower support stake, to ensure that steel column has certain adjusting leeway and construction after reaching design buried depth
Space, later utilize above-mentioned apparatus, using on steel column laser guidance device and above-mentioned apparatus as fulcrum, pass through Three Degree Of Freedom
The internal hydraulic pressure clamper of underthrust construction machinery carries out the adjusting of depth, center and verticality, wants to reach design
It asks.
Construction procedure includes:
A) preparation of construction；
B) drilling machine is removed in pour stake body by concrete completion, clears up aperture；
C) installation of Three Degree Of Freedom underthrust machinery tune, positioning, leveling；
D) steel column is hung in；
E) upper mounting plate clamps steel column, and lower platform releasing orientation is pushed by linear motion device and carried out vertical
Degree adjustment；

One pile for one column proposes high requirement to verticality as permanent structural column.One pile for one column top steel column
Verticality require to reach 1/2000, in order to ensure the insertion depth of steel column in one pile for one column construction, center and vertical
Degree meets design requirement, need to accomplish claimed below:
1) fixation of laser guidance device and steel column must be close, secured.
2) present apparatus decomposes lifting, accomplishes that base center, the Clamping Center of upper and lower clamp assemblies and pile center's deviation are little
In 1 cm, and ensure the stability of straightening frame.
3) after steel column is inserted under guide hydraulic clamping device under, different location installs sensing with steel column
Device, sensor must not be placed on same section or same straight line, more accurately to reflect the verticality of steel column.
4) after steel column lifts up into the present apparatus, start the underthrust construction that steel column is carried out with upper mounting plate internal clampers.It is logical
It crosses after setting basic parameter, equipment can carry out insertion automatically and verticality adjusts work.
5) verticality for the obliquity sensor monitoring steel column that the monitoring of equipment overall process is mounted on steel column, if hung down
Straight degree is maintained within coarse adjustment range, and equipment only repeats circulation and is downwardly into work, if the verticality reading read
More than the coarse adjustment range limiting value of setting, after the insertion circulation currently carried out terminates, equipment automatically switches to vertical adjustment mode,
The closed-loop automatic control of verticality is realized by the progressive error of three electric cylinders of process control.
6) control for carrying out insertion depth in steel column down process by the scale on shaft, is adjusted subsequent in place
It is continuous that projected depth in lower support stake will be inserted under steel column, and after inspection center position, verticality are qualified to steel column into
Row is fixed.
