8th, guide rail 9, rotating shaft 10, stay-bolt 11.
Embodiment：As Figure 1-4, the present embodiment is appeared posture in high precision more particularly to a kind of for miniature steel push pipe
Sub-controlling unit, the sub-controlling unit includes the spacing top iron 1 set gradually along the bearing of trend of guide rail 9 and planer-type is embraced
Hoop 6, by the setting of two above position-limit mechanism, realize that steel push pipe 8 is limited during jacking of being appeared to steel push pipe 8 to be produced
Rotation and attitude misalignment, it is ensured that high-precision gesture stability of appearing.
As shown in Figure 1, 2, 3, spacing top iron 1 is installed on the rail 9, and under the pushing tow of jack, spacing top iron 1 can incite somebody to action
Jacking force is acted on the end face of steel push pipe 8, and then promotes it to move on the rail 9.Distinguish in the bottom surface both sides of spacing top iron 1
It is provided with limit card slot 3 and is realized by bolt 5 and is fixed, the installation site of limit card slot 3 corresponds to the set location of guide rail 9,
It is slidably matched so as to be formed between guide rail 9, wherein, the plane free clearance between limit card slot 3 and guide rail 9 is 5mm, elevation
Free clearance is 1mm, and plane and the displacement on elevation occurs so as to limit spacing top iron 1；Set on the pushing tow face of spacing top iron 1
It is equipped with two limits and turns round blocks 2, at the same time, on the inner tubal wall by pushing tow end of steel push pipe 8 be provided with two is adapted therewith
Corresponding limit turns round part（Not shown in figure）, i.e., the limit torsion part on steel push pipe 8 and the limit on spacing top iron 1 turn round the set location phase of block 2
Mutually it is adapted to and forms mutually limit and turn round, so as to avoids the generation of steel push pipe 8 rotation during spacing top iron 1 is to the pushing tow of steel push pipe 8；
Certainly, in the case where being based on limit and turning round anti-rotational purpose, single limit can also be only set to turn round block on the pushing tow face of spacing top iron 1
2, at the same time, in steel push pipe 8 by one stopper slot of pushing tow end set（Not shown in figure）, it is spacing during pushing tow
Push up in the stopper slot of the end of the limit torsion insertion steel of block 2 push pipe 8 on iron 1 so as to form rotary stopper.In order to realize spacing top iron 1
Quick handling installation, welds at the top of it and is provided with multiple hangers 4.
As shown in Figure 3,4, planer-type anchor ear 6 constructs in arched door formula, and steel push pipe 8 passes through, mainly by lower base 6a
And top vault 6b is combined；Lower base 6a is divided into the both sides of guide rail 9 and is fixed on same foundation plate with track 9
On, lower base 6a main body uses 10# channel-section steels；Top vault 6b semicirculars in shape construction, and reversible is arranged on bottom base
On seat 6a, so as to form arched door shape in closed state, reversible installation herein refers to：Top vault 6b right side lower end
It is made up of and is hinged rotating shaft 10 between portion and lower base 6a right side upper end, and top vault 6b left side bottom is with
Portion pedestal 6a left side upper end is made up of stay-bolt 11 and bolted；In order to realize the control for posture of being appeared to steel push pipe 8,
The three sets of limited roller radially set devices 7, i.e., the installation axle of each limited roller device 7 are uniformly installed on the vault 6b of top
Line points to the centre point of steel push pipe 8, wherein a set of in vertically arranged, two sets are symmetrical arranged by line of symmetry of vertical axis in addition,
Interval angle between three is 45 °.
As shown in Figure 3,4, limited roller device 7 be specifically by spacing screw mandrel 7a, spring mechanism 7b and roller 7c successively
It is formed by connecting, wherein, spacing screw mandrel 7a sets and is fixed thereon through top vault 6b, consequently facilitating workmen passes through
Spacing screw mandrel 7a exposed parts are adjusted；The outside wall surface that roller 7c is close to steel push pipe 8 is set, specific using φ's 100
Nylon wheel；Spring mechanism 7b is arranged between spacing screw mandrel 7a and roller 7c, to provide 10mm Free Compression amount, it is ensured that rolling
Wheel 7c can be close in the outside wall surface of steel push pipe 8 all the time.
As Figure 1-4, it is applied to miniature steel push pipe in the present embodiment in high precision to appear the sub-controlling unit of posture
Specific works method comprises the following steps：
（1）Steel push pipe 8 is lifted on guide rail 9, will be closed afterwards in the top vault 6b upsets opened as shown in Figure 4 under state
Close on lower base 6a, and adjusted by stay-bolt 11 and fasten and bolt locking；
（2）Three sets of limited roller devices 7 on regulation top vault 6b are tightened respectively, by tightening spacing screw mandrel 7a, so that
The roller 7c for obtaining its leading section is close to the outside wall surface of steel push pipe 8, so as to limit the attitude misalignment of steel push pipe 8；It should be noted that
The Free Compression amount 10mm that spring mechanism 7b is provided provides certain screen resilience, so as to be tightened certain under error still
It is old to ensure that roller 7c is close in the outside wall surface of steel push pipe 8；
（3）Afterwards, spacing top iron 1 is lifted to guide rail 9 through its hanger 4, i.e. the rearward end of steel push pipe 8, and by spacing top iron 1
On limit card slot 3 with the clamping of guide rail 9 form be slidably matched；Using jack pushing tow spacing top iron 1, so that spacing top iron 1
On limit turn round the limit of block 2 and the rearward end of steel push pipe 8 and turn round part or stopper slot forms limit torsion matches；
（4）Under jack effect, spacing top iron 1 continues pushing tow steel push pipe 8 and appeared, and the limit on spacing top iron 1, which turns round part 2, prevents steel
Push pipe 8 rotates, and the posture of appearing of each set limited roller device 7 control steel nail pipe 8 on planer-type anchor ear 6, prevents
Deviation；
（5）When spacing top iron 1 is needed by planer-type anchor ear 6, the stay-bolt 11 in the left side of planer-type anchor ear 6 can be beaten
Open, dug top vault 6b to the right using the rotating shaft 10 on right side, so as to allow spacing top iron 1 to pass through；Treat that spacing top iron 1 is logical
Later, top vault 6b is overturn and closed；
（6）After completing to appear, same digs top vault 6b, the lifting of the tube coupling of steel push pipe 8 is carried out, when steel push pipe 8
Tube coupling on the rail 9 after rigging out, the stay-bolt 11 in the left side of planer-type anchor ear 6 is relocked, and by the three of top
Cover spacing screw mandrel 7a to tighten, restart jacking.
