Description
Technical field
The utility model relates to boring grabs, specially water-cooling wall annular header boring grab.
Background technique
Coal is the superior resources of our province, accounts for the 22.6% of National Resources reserves.Wherein " three high " (high-sulfur, high ash, high ash
Fusing point) colm accounts for 30% or more of the whole province's coal resources total amount.The world that the Jin Hualu of our company production represents industry technology is high
Degree, the technology have the advantages that coal slurry gasifier stabilization, reliable, it may have good excellent of water wall gasifier coal adaptability
Gesture is particularly suitable for high-sulfur, high ash, high ash melting point " three high " coal gasification.The technology coal scope of application is wider, can consume big
Measure colm.The main member of Shanxi China furnace core water-cooling wall is exactly annular header, and structure is ring pipe, endless tube inner ring surface arrangement
There are many counterbores not of uniform size.Limited by existing equipment technical conditions, process annular header inner ring surface counterbore difficulty compared with
Greatly, it is difficult to ensure that the verticality and position precision of counterbore and inner ring surface.Therefore, designing one kind being capable of clamping water-cooling wall annular header
Fixture, guarantee processing inner ring surface on counterbore machining accuracy be very it is necessary to.
Summary of the invention
The utility model, which solves existing fixture at present, not can guarantee the counterbore position essence of water-cooling wall annular header inner ring surface
The problem of degree and verticality, provide a kind of water-cooling wall annular header boring grab.
The utility model is achieved through the following technical solutions：Water-cooling wall annular header boring grab, including rectangle
Bottom plate has two pieces of slide plates along baseplate width direction parallel support on the bottom plate, the slide plate both ends respectively with the long side of bottom plate
It is connected by clamp, for clamp lower part buckle in the guide groove of base plate long side lower surface, clamp top is screwed with stop screw；Two
Slide plate upper surface described in block is vertically fixed two pieces of support plates parallel with lower surface of base plate guide groove, the support plate bottom respectively
It is fixed with stiffener plate between slide plate, support rollers, the support roller on two pieces of slide plates are supported by between the support plate top
Sub- axis is in same level and is parallel to each other, and the support plate edge on the outside of two support rollers is fixed with the horizontal drawing of support plate
Muscle, is screwed with fishbolt between two support rollers in the support plate of inside, the fishbolt is towards one between support plate
End is fixed with clamping cushion block；The support base being fixed in the middle part of the plate upper surface between two pieces of slide plates.It is parallel on bottom plate
Two pieces of slide plates are provided with, two pieces of slide plates can be slided along guide groove, the distance between plate supported on both sides be adjusted, to adapt to different-diameter
Water-cooling wall annular header, stop screw be used for fixed glides position.Support rollers between two pieces of parallel support plates are used for
Water-cooling wall annular header outer rim is supported, and facilitates annular header to roll and adjusts bore position.Support plate girt, stiffener plate
For fixed support plate, guarantee parallel therebetween.Fishbolt end fixes to clamp cushion block, for clamping annular header, prevents
Annular header glances off and roll displacement when only drilling.Support base is used to support annular header.
The utility model has the following advantages that：1, structure is simple, cost of manufacture is cheap；2, support plate and fishbolt are common
Limit guarantees that inner ring surface borehole accuracy is high；3, facilitate and adjust to adapt to the water-cooling wall annular header of different size drilling demand.

Specific embodiment
Water-cooling wall annular header boring grab, the bottom plate 1 including rectangle are parallel along 1 width direction of bottom plate on the bottom plate 1
Two pieces of slide plates 2 are supported by, 2 both ends of slide plate are connect with the long side of bottom plate 1 by clamp 3 respectively, the 3 lower part buckle of clamp
In the guide groove of 1 long side lower surface of bottom plate, clamp top is screwed with stop screw 4；Two pieces of 2 upper surfaces of slide plate are vertical solid respectively
Surely there are two pieces of support plates 5 parallel with 1 lower surface guide groove of bottom plate, be fixed with reinforcing rib between 5 bottom of support plate and slide plate 2
Plate 6 is supported by support rollers 7 between 5 top of support plate, and 7 axis of support rollers on two pieces of slide plates 2 is in same level
Interior and be parallel to each other, 5 edge of support plate in two 7 outsides of support rollers is fixed with support plate girt 8, two support rollers 7
Between inside support plate 5 on be screwed with fishbolt 9, the fishbolt 9 is fixed with clamping towards one end between support plate 5
Cushion block 10；1 upper surface middle part of bottom plate is fixed with the support base 11 between two pieces of slide plates 2.
In use, water-cooling wall annular header is put into vertically between support plate 5, annular header lower support is in support base 11
On, the stop screw 4 on the clamp 3 of side is first tightened, the slide plate 2 of the other side is translated, it is ensured that the support rollers 7 in support plate 5
It is respectively supported in annular header outer rim, tightens the stop screw 4 on the clamp 3 of the fixed other side, it then will be in support plate 5
Fishbolt 9 is fixed annular header together with 10 precession of cushion block is clamped, and perforating device is pushed into annular header inner ring surface,
Face inner ring surface is punched, and after drilling to a hole location, is unclamped fishbolt 9 and is clamped cushion block 10, by annular header
Rotate by a certain angle around own axes, then tighten fishbolt 9, next hole location carry out drilling operation, and so on until
Inner ring surface drilling finishes.
