Description
Technical field
The utility model is related to part guiding technique field, the mast guider of more particularly to a kind of rotary drilling rig.This
Utility model further relates to a kind of include the rotary drilling rig of above-mentioned mast guider.
Background technology
Rotary drilling rig as pore-forming operation in a kind of suitable building foundation engineering construction machinery, bored concrete pile, diaphragm wall,
It is used widely in a variety of foundation constructions such as strengthening of foundation.
For rotary drilling rig, its mast assembly is its important composition structure.Specifically, as shown in Figure 1 to 11, mast
Bar assembly includes catead 03, mast 02, pressurization elevator 09, secondary elevator 08 etc., and its middle mast 02 includes from top to bottom cloth successively
Upper mast, middle mast, the lower mast put, mast 02 and guide rail 01 constitute mast guider.Operating mechanism's bag of rotary drilling rig
Elevator 04, unit head 07, arbitrary-movement articulator 05, drilling rod 06 etc. are included.Mast guider is the installation branch of drilling rod 06, unit head 07
The guiding parts of support part part and its drilling depth that works.The guide rail 01 of the left and right sides of mast 02, the work to unit head 07, arbitrary-movement articulator 05
Drilling depth play a part of to dominate to.
Catead 03 is installed on the top of mast 02, is connected during work by bolt with upper mast 02.On catead 03
Major and minor elevator pulley is lifting, declines drilling rod 06 and the important support of object lifting to change the hoisting rope direction of motion
Part.Upper mast, middle mast, lower mast are connected in sequence by bolt two-by-two.
Pressurization elevator 09 is made up of hydraulic speed reducer structure, reel, elevator bearing, two steel wire ropes etc., and pressurization elevator 09 leads to
Bolt connection is crossed on mast 02, the assembly pulley on two steel wire ropes, its steel wire rope and unit head 07 is wound on pressurization elevator 09
Winding, steel wire rope is driven by the rotating of reductor, drives rising for drilling rod 06 to pull out and pressurize to complete unit head 07, to bore
Bar 06 is smoothed out drilling.
Elevator 04 is the transition apparatus that drilling rod 06 is connected with steel wire rope, while drilling rod 06 is ensured in rotary drilling,
Steel wire rope is not by larger moment of torsion.The upper end of elevator 04 is hinged with steel wire rope, and lower end is hinged with drilling rod 06.
Wherein, unit head 07 is by hydraulic motor, reductor, headstock, buffer unit, sliding rack, connecting plate, platen group
Into.Unit head 07 provides torsion power for drilling tool, and working resistance is applied on unit head 07 through bull gear, and unit head 07 is removed and born
Outside Torsional Loading, the pressure produced also subject to pressue device.Ear mount and 02 liang of side rails of mast on the balladeur train of unit head 07
01 is slidably connected contact.
Arbitrary-movement articulator 05 is the servicing unit that drilling rod 06 works, and its one end is connected with equipped with bearing and with drilling rod 06, right
Drilling rod 06 plays revolving support；The other end is provided with guide groove, is slidably connected with 02 liang of side rails 01 of mast, is that drilling rod 06 works
Guiding parts, helps the normal work of drilling rod 06.
Drilling rod 06 is the important component that rig transmits moment of torsion and pressure to drilling tool.The one end of drilling rod 06 is hinged with elevator 04,
Through unit head 07, its other end is hinged with drilling tool.
Operationally, unit head 07 provides torsion power to rotary drilling rig for drilling tool, and unit head 07 bears torsional load effect
Outside, the pressure produced also subject to pressue device.Four ear mount on power head device balladeur train up and down everywhere with lower mast
On guide rail 01 contact.
The torsion load and vertical load being subject on unit head 07 are delivered to what is be in contact with it by the ear mount of unit head 07
On the face of guide rail 01 on lower mast.During due to rotary drilling rig operation, pressue device is applied to plus-pressure on unit head 07, now moves
The position of power first 07 can up and down be moved on lower mast.When unit head 07 is both by the plus-pressure of pressue device during operation
When again by torque resistance, the load on guide rail 01 being delivered on lower mast is the load larger period in work progress, because
Guide rail 01 is connected together with lower mast body by welding manner, and weld seam herein belongs to work weld seam, the load born
It is larger.
Traditional guide rail 01 has two kinds of U-shaped guide rail and rectangular guideway, and wherein U-shaped guide rail uses steel plate by mechanical bending
Into rectangular guideway is directly from the different in nature rectangular steel tube of cold-drawn or the different in nature rectangular steel pipe of cold-drawn according to the making of design requirement length
Into.U-shaped guide rail and rectangular guideway are all made in body production process by cold-rolling process.Because being led using cold-rolling process
The shaping bending of rail 01 corner is also easy to produce defect, and rectangular guideway is fixed welding position when being welded with mast 02, it is impossible to avoid this
Welding is carried out at bending turning, is influenceed this position easily to produce defect by welding heat affected zone and (is entered according to CEN ISO/TR 15608
Cold forming region (including adjacent surface in the range of 5 × t) is only allowed to certification in the material and EN 15085-3 of row packet
Rank is welded for CL3 structure.).
The unilateral tubaeform welding junction of self-assembling formation when rectangular guideway is welded with mast 02, easily produces during welding and does not weld
Saturating phenomenon, such a notch effect is easy to cause stress concentration, so as to reduce the fatigue resistance of weld seam.And rectangle is processed to lead
The different in nature square steel tube of cold-drawn or the different in nature rectangular steel pipe of cold-drawn that rail is used relatively are hard to keep the flexibility of steel pipe after manufacture, so
It is processed into before guide rail 01, it is necessary to smoothed to steel pipe, adds additional process, technique is complex.
Also, the firm of guide rail 01 is caused because relatively thin in its processing raw material wall thickness itself with rectangular guideway due to U-shaped guide rail
Degree, intensity are more weak, therefore contraction distortion can be larger when being welded with mast 02, are difficult to keep the straight line of the overall weldment of postwelding
Degree and flatness (linearity and planarity requirements of rotary digging driller mast 02 are all very high), cause the feature of mast guider
It is weaker, cause the service life of mast guider shorter.
Therefore, how to extend the service life of mast guider, be that those skilled in the art's technology urgently to be resolved hurrily is asked
Topic.
