Description
Technical field
The present invention relates to hydraulic support foundation processing methods, more particularly, to hydraulic support foundation entirety bore hole and centering side
Method.
Background technology
Hydraulic support is the works for controlling coal working face mine pressure, mainly by hydraulic cylinder（It is column, very heavy
Top）, load assembly（Pedestal, caving shield, top beam, front and rear connecting rods etc.）, push unit, control system and other auxiliary devices
Composition.Hydraulic support foundation is connected by front and rear connecting rods with caving shield.When hydraulic support supporting height and supporting intensity compared with
Gao Shi, to meet matching requirements and overall stability, the hinge hole concentricity being hinged with front and rear connecting rods on pedestal must satisfy
No more than 0.5mm, assembled process is added to cannot be satisfied requirement by pre- bore hole at this time, it is necessary to carry out whole bore hole.
With the needs that the development of coal mineral industries and medium-thickness seam are exploited, high working face hydraulic support is increasingly by joyous
It meets, while the record of supporting height and supporting intensity constantly refreshes.But with the continuous increasing of supporting height and supporting intensity
Add, the structural member that hydraulic support needs is also more and more huger, the case where especially pedestal will appear superelevation, is more than equipment sometimes
Normal process ability, will be unable to be processed using traditional processing method.And it purchases new process equipment and needs to spend greatly
The fund of amount, it is up to a million easily, greatly increase business burden.
To solve the above problems, being attempted to the base plate plane of hydraulic support foundation upward, be inverted in bidirectional boring machine work
Make on platform, centering is carried out on the basis of the bottom plate lower plane of pedestal.But since the upper surface of pedestal has compared with multi-step, do not have
Centering plane is needed first to lie against pedestal on face plate, be drawn on the basis of the bottom plate of pedestal before allowing for bore hole in this way
Line, then pedestal back-off is positioned on bidirectional boring machine workbench, it could start to carry out centering by scribing line, cause centering operation numerous
It is trivial, take considerable time with energy and centering precision it is not high.
Invention content
Present invention aims at provide convenient, the accurate hydraulic support foundation entirety bore hole of one kind and aligning method.
To achieve the above object, the present invention takes following technical proposals：
Hydraulic support foundation entirety bore hole aligning method of the present invention, carries out as steps described below：
Before the first step, pedestal and the outer main reinforcement assembly of the pedestal both sides are welded, first respectively with this in each outer main reinforcement
Processing technology hole on the basis of main reinforcement bottom surface and front end face, the fabrication hole are located at two that the main reinforcement is hinged with front and rear connecting rods
Pre- bore hole center vertical line intersection position；
Two outer main reinforcement assembly are welded on pedestal both sides by second step by design requirement, and unsplit bedplate is made；
After being spaced apart two cushion blocks on bidirectional boring machine workbench, the unsplit bedplate is tipped upside down on described in two for third step
On cushion block；
4th step, to unsplit bedplate centering, make bidirectional boring machine both sides boring bar front end holding screw that can stretch into unsplit bedplate
Outside both sides in main reinforcement in corresponding fabrication hole, boring cutter adjustment bidirectional boring machine coordinate system is then loaded onto, two institutes to be processed are observed
State pre- bore hole, two pre- bore holes to be processed made to adjust to there is allowance to be considered as centering, by unsplit bedplate with it is two-sided
Boring table is fixed, you can is started the pre- bore hole to be processed to two and is carried out Boring operation.
Side positioning device is provided on the cushion block, the side positioning device is to be welded on determining for cushion block side vertically upward
Position plate, offers screw hole on the positioning plate, adjusting bolt is bolted in the screw hole.
The present invention not only solves the high insufficient problem of bidirectional boring machine boring, while on the basis of base end face, ensure that bottom
Precision of the pitch-row of pre- bore hole during overall processing in main reinforcement, eliminates and carries out the numerous of centering operation by scribing line outside seat both sides
It is trivial, greatly improve 30% or more production efficiency.
Description of the drawings
Fig. 1 is the schematic diagram to hydraulic support foundation entirety bore hole centering according to the method for the present invention.
Fig. 2 is the schematic diagram that unsplit bedplate of the present invention tips upside down on cushion block.
Specific implementation mode
As shown in Figure 1, 2, the hydraulic support foundation entirety bore hole aligning method, carries out as steps described below：
Respectively there are one outer main reinforcements 1,2 for the first step, hydraulic support foundation both sides, before the assembled welding of outer main reinforcement 1,2 of pedestal and both sides,
First in each outer main reinforcement respectively by the main reinforcement bottom surface 3 and front end face 4 on the basis of processing technology hole 5, fabrication hole 5 is located at the main reinforcement
The center vertical line 8 for the two pre- bore holes 6,7 being hinged with front and rear connecting rods, 9 intersection positions, fabrication hole 5 are used for auxiliary when overall processing
Help centering, therefore, the diameter of fabrication hole 5, according to processing when boring cutter with knife bar can gap pass through；
Two outer main reinforcements 1,2 assembly are welded on pedestal both sides by second step by design requirement, and unsplit bedplate is made；
Unsplit bedplate after being spaced apart two cushion blocks 11,12 on bidirectional boring machine workbench 10, is tipped upside down on two pads by third step
On block 11,12, ensure that boring height can meet the processing request of boring machine after being buckled to；
4th step, to unsplit bedplate centering, make bidirectional boring machine both sides boring cutter knife bar front end holding screw that can stretch into integral bottom
In the outer main reinforcement in seat both sides in corresponding fabrication hole 5, then load onto boring cutter adjustment bidirectional boring machine coordinate system, observe two it is to be processed
Pre- bore hole 6,7 makes two pre- bore holes 6,7 to be processed adjust to there is allowance to be considered as centering, by unsplit bedplate with
Bidirectional boring machine workbench 10 is fixed, you can is started the pre- bore hole 6,7 to be processed to two and is carried out bore hole finishing operations.
When to unsplit bedplate centering, by using mechanic jacks tune between bidirectional boring machine workbench 10 and unsplit bedplate
Whole height simultaneously increases parallels realization on cushion block 11,12；Meanwhile adjusting the side positioning device on cushion block 11, i.e.,：By adjusting fixed
Adjusting bolt 14 on the plate 13 of position, makes bidirectional boring machine both sides boring cutter knife bar front end holding screw that can stretch into fabrication hole 5 i.e.
It can.
