Two kinds of drilling rods can be used in cooperation with the drilling bucket in an interchangeable mode.
Description
Technical field
The utility model relates to a kind of drilling bucket square toes, relates to specifically a kind of multifunctional rotary excavating driller drilling bucket square toes, belongs to rotary drilling rig technical field.
Background technology
In rotary drilling rig when work, is transmitted the moment of torsion of drilling rig power plant output and plus-pressure to rotary drilling digger by drilling rod, then by rotary drilling digger, cuts ground realization and creeps into.And the square toes of drilling rod and drilling bucket are realized the transmission of moment of torsion by matched in clearance, by under add pressure surface laminating transmit plus-pressure, by bearing pin fixed delivery pulling force.The drilling rod using on domestic market mainly contains two kinds of square toes specifications, is respectively precious high kelly bar and domestic kelly bar, and the rotary drilling digger of answering in contrast also exists two kinds of specifications, is respectively precious high drill with ferrule bucket and domestic drill with ferrule bucket.Two kinds of drilling rods are used in conjunction with the drilling bucket of dimension respectively, can not realize exchange.
Utility model content
Problem to be solved in the utility model is in order to overcome the above-mentioned defect of traditional rotary drilling digger, and a kind of multifunctional rotary excavating driller drilling bucket square toes that can be respectively used in conjunction with multiple drilling rod are provided.
In order to address the above problem, the utility model by the following technical solutions:
Use drilling bucket square toes, comprise drilling bucket body, the inside of described drilling bucket body has the drilling rod connection chamber that can peg graft with drilling rod, and the bottom of described drilling rod connection chamber is provided with mounting base; Position near mounting base top on described drilling bucket body is provided with two coaxial second time installing hole and two first time coaxial installing holes, and the distance of the axis of two second time installing holes or two axis of first time installing hole and the upper surface of mounting base is 90 ± 0.5mm; Position near second time installing hole top on described drilling bucket body is provided with installing hole on coaxial two second, and the center to center distance of installing hole and second time installing hole is 100 ± 0.5mm on second; Position near first time installing hole top on described drilling bucket body is provided with installing hole on coaxial two first, and the distance of the axis of installing hole and the upper surface of mounting base is 270 ± 0.5mm on two first.
Below the further optimization of the utility model to such scheme:
On second, the axis of the axis of installing hole and second time installing hole be arranged in parallel.
Further optimize: the upper surface of described mounting base is 460mm apart from the distance of drilling bucket body upper end.
Further optimize: second time installing hole and first time mounting hole site are in same level, and the axis of the axis of two second time installing holes and two first time installing holes is decussation setting.
When the high kelly bar of the supporting treasured of this drilling bucket, bottom second on installing hole and first time installing hole can normally assemble two bearing pins and use.When supporting domestic kelly bar uses, can be at the thick steel plate of the upside pad dress 120mm of square toes base plate, on top newly increase two first, installing hole can be used in conjunction with domestic kelly bar, has realized drilling bucket and two kinds of interchangeable being used in conjunction with of drilling rod.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model embodiment;
Accompanying drawing 2 is that A-A in accompanying drawing 1 is to sectional view.
In figure: 1-drilling bucket body; 2-mounting base; Installing hole on 3-first; First time installing hole of 31-; Installing hole on 4-second; Second time installing hole of 41-; 5-drilling rod connection chamber.
The specific embodiment
Embodiment, as shown in Figure 1 and Figure 2, a kind of multifunctional rotary excavating driller drilling bucket square toes, comprise drilling bucket body 1, and the inside of described drilling bucket body 1 has the drilling rod connection chamber 5 that can peg graft with drilling rod, and the bottom of described drilling rod connection chamber 5 is provided with mounting base 2; The upper surface of described mounting base 2 is 460mm apart from the distance H of drilling bucket body 1 upper end.
Position near mounting base 2 tops on described drilling bucket body 1 is provided with two coaxial second time installing hole 41 and two first time coaxial installing holes 31, second time installing hole 41 and first time installing hole 31 are positioned in same level, and the axis of the axis of two second time installing holes 41 and two first time installing holes 31 is decussation setting.
The distance A of the axis of the axis of two second time installing holes 41 or two first time installing holes 31 and the upper surface of mounting base 2 is 90 ± 0.5mm.
On described drilling bucket body 1, near the position of second time installing hole 41 top, being provided with on coaxial two second the axis of installing hole 4 and the axis of second time installing hole 41 on installing hole 4, the second be arranged in parallel.
