Bottom plate is orthogonal to be vertically arranged on roller support.
It is further characterized by,
The idler wheel that is vertically arranged includes two, and the both sides that idler wheel is located at the horizontal idler wheel respectively are vertically arranged described in two；
The angle bracket is the simple rack of shaped steel welding, including transverse slat, riser, one end of the transverse slat and the riser
One end vertical welding, the other end of the other end of the transverse slat and the riser is welded with is in respectively with the transverse slat, riser
The inclined plate of certain angle connection, the bottom plate bottom end of the modular turning rolls is fixedly installed on the top end face of the inclined plate；
Kidney slot is provided on the bottom end end face for being vertically arranged roller support, the roller support that is vertically arranged passes through the waist by screw
Type hole is mutually fixed with the bottom plate.
Above structure using the present invention, the setting of angle bracket can ensure the angle accurate positioning of eccentric orfice；Angle
At least three modular turning rolls on stent is installed, ensure that annular header can be reliably placed on turning rolls, carry significantly
High security reliability；Idler wheel is vertically arranged mounted on being vertically arranged on roller support, easily front and rear can be adjusted by being vertically arranged roller support
Section is vertically arranged the position of idler wheel, and so as to meet the requirement for adapting to different-diameter annular header, versatility is good, is well positioned to meet
Actual production uses.
Further, angle bracket is the simple rack of shaped steel welding, including transverse slat, riser, inclined plate using
Convenient disassembly afterwards can reduce place occupancy；
Further, it is vertically arranged the setting of kidney slot on the end face of roller support bottom end and can further facilitate and be vertically arranged roller support position
It adjusts, makes installation and adjustment simple and convenient.

Specific embodiment
As shown in Figures 1 to 8, a kind of annular header eccentric orfice adjustable drilling stage apparatus, including being welded by shaped steel
The angle bracket 1 formed, angle bracket 1 include transverse slat, riser, one end of transverse slat and one end vertical welding of riser, transverse slat
The other end of the other end and riser is welded with the inclined plate being connect at an angle with transverse slat, riser respectively, in the present embodiment tiltedly
Angle between plate and the transverse slat is 30 degree, and 21 bottom end of bottom plate of modular turning rolls 2 is fixedly installed in the top end of inclined plate
On face；At least three modular turning rolls 2 on angle bracket 1 is installed, 5 modular turning rolls 2 are installed in the present embodiment,
Modular turning rolls 2 includes the horizontal idler wheel 22 being fixed on bottom plate 21 and two groups are vertically arranged idler wheel 23, the horizontal horizontal peace of idler wheel 22
Top centre position loaded on bottom plate, two are vertically arranged idler wheel 23 and are arranged symmetrically respectively positioned at the both sides of horizontal idler wheel 22, are vertically arranged rolling
Wheel 23 is fixedly installed in and bottom plate 21 is orthogonal is vertically arranged on roller support 24, is vertically arranged on the bottom end end face of roller support 24 and is opened
There is kidney slot 25, be vertically arranged roller support 24 and fixed by screw across waist-shaped hole 25 with 21 phase of bottom plate.
Its concrete operating principle is as described below：Apply the present invention to the annular header in boiler manfacturing installation and partially
During the drilling use in heart hole, easy angle bracket 1 first is welded with shaped steel, ensures that angle is accurate, then in angle bracket 1
Upper installation modular turning rolls 2, according to the size of annular header diameter, the installation site of general determining module formula idler wheel 2, then hang
Fill annular header 3；Meanwhile adjust and be vertically arranged roller support 24, it is made to have preferable support limit to act on to annular header 3, is ensured
Annular header 3 can be freely rotated on modular turning rolls 2, while annular header does not occur and turns the danger fallen partially.Pass through
Horizontal idler wheel 22 and two groups of rollings for being vertically arranged idler wheel 23 can realize hand-turning during annular header drilling, by adjusting idler wheel
The position of idler wheel is vertically arranged in frame, the use of different-diameter annular header can be met.
In drill process, position is punched downwards perpendicular to annular header at puncher B shown in Fig. 1, annular collection
Case can rely on its own gravity or external fixation device to be fixed on angle bracket 1, to prevent annular header in drill process from sending out
Raw movement, angle bracket 1 can ensure that the eccentric orifice angle drilled out in puncher boring procedure is accurate, and two groups are vertically arranged idler wheel 23 and need
Mounted on the inside of annular header 3, modular turning rolls 2 was both played a supporting role at this, ensured that annular header 3 can be in module
It is freely rotated on formula turning rolls 2, and can ensure that the danger for turning to fall partially does not occur in rotation process for annular header 3, meanwhile,
It can be collided at 3 inside of annular header to avoid being generated when lifting annular header 3,3 convenience of guarantee lifting annular header,
Safety.
