Using the drilling device and the drilling rod, the operation is simple, the working efficiency is relatively greatly increased and the sliding pin type drilling rod is safer.
Description
The application is July 7 2010 applying date, application number 201020251694.3, and name is called the dividing an application of utility model application of " a kind of sliding pin type drilling rig and drilling rod ".
Technical field
The utility model relates to the drilling technique field, relates in particular to a kind of sliding pin type drilling rod.
Background technology
In current geotechnical investigation, it is commonplace to adopt three-wing bit to be rotated the drilling method that creeps into, this method normally is connected drill bit with drilling rod, by the power drive drilling rod rotation of rig, the rotation of drilling rod drive drill bit also relies on drilling rod to conduct oneself with dignity and creeps in the soil layer.In drilling process, the top of drilling rod connects the bath head, and is connected with slush pump by water pipe that slurry conveyed or water etc. lubricate, cooling fluid.The rotation of drilling rod is to drive by the rotation of the mill on the rig (driving the mill rotation by diesel engine), be inserted with two driving levers on the mill, be connected by clamper between driving lever and drilling rod, clamper is held drilling rod tightly, the ear on both sides is hooked on the driving lever, so just drives the rotation of drilling rod by the rotation of mill.The height of driving lever can not be oversize, otherwise rock when creeping into too greatly, dangerous, therefore is traditionally arranged to be about 1m.Because clamper hugs drilling rod, when each clamper drops to the mill top with drilling rod, just can not creep into again, must unclamp clamper, it is lifted to driving lever top, holding drilling rod again tightly creeps into, whole drilling process needs the repeated using clamp holder clamping---creeps into---repetitive operation of lax---lifting---clamping, the work that repeats like this has a strong impact on the probing operating efficiency, and because clamper is to be hooked on the driving lever, when clamper is positioned at the driving lever middle and upper part, produce bigger torsion in the drilling process, can produce bigger converse rotating force when relaxing after stopping boring, easily cause driving lever to eject from jack, potential safety hazard is very big.
Therefore, those skilled in the art is devoted to develop a kind of high efficiency, and the substitute of safe and practical clamper.
The utility model content
Because the above-mentioned defective of prior art, technical problem to be solved in the utility model provides a kind of high efficiency, and the substitute of safe and practical clamper.
For achieving the above object, the utility model provides a kind of sliding pin type drilling rig, comprises body; Described body is provided with and can holds the driving lever jack that driving lever is free to slide and can hold the drilling rod jack that drilling rod is free to slide; Be provided with in the described drilling rod jack the transmission of power of the described body transmission groove to the drilling rod.
Preferable, the cross section of described drilling rod jack is made of at least two sections end to end arc sections; Described arc section comprises the drilling rod arc section of corresponding drilling rod and the transmission arc section of corresponding transmission groove.
Preferable, described transmission arc section evenly is provided with on the circle of described drilling rod arc section correspondence.
Preferable, described transmission arc section is two sections.
Preferable, the cross section middle part of described body is a rectangle, two ends are the semicircle tangent with rectangle.
The utility model also provides a kind of sliding pin type drilling rod simultaneously, comprises the drilling rod body; Be wholely set drive block on the length direction of described drilling rod body.
Preferable, described drive block is and the identical cylinder of described drilling rod body length.
Preferable, described drilling rod body is provided with at least two described drive blocks.
Described drive block evenly is provided with on described drilling rod body.
The beneficial effects of the utility model are: the rig mill bores when moving, because the sliding pin type drilling rod can be free to slide, therefore, in whole drilling process, need only sliding pin type drilling rig of installation and sliding pin type drilling rod, can finish whole process creeps into, improve operating efficiency greatly, changed loaded down with trivial details workflow; And during work, sliding pin type drilling rig drops on mill driving lever jack top always naturally, and driving lever is difficult for producing bounce-back and skids off phenomenon, and working security also is improved.
Be described further below with reference to the technique effect of accompanying drawing, to understand the purpose of this utility model, feature and effect fully design of the present utility model, concrete structure and generation.

The specific embodiment
Embodiment 1: as shown in Figure 2, a kind of sliding pin type drilling rig comprises body 1, and the cross section middle part of body 1 is a rectangle, and two ends are the semicircle tangent with rectangle.
The cross section of drilling rod jack 3 is made of four sections end to end arc sections, and arc section comprises the drilling rod arc section 32 of corresponding drilling rod and the transmission arc section 33 of corresponding transmission groove 31.Wherein, drilling rod arc section 32 is oppositely arranged, and transmission arc section 33 is oppositely arranged.
As shown in Figure 3, a kind of sliding pin type drilling rod comprises drilling rod body 10, is welded with drive block 20 on the length direction of drilling rod body 10, and drive block 20 is and the identical cylinder of drilling rod body 10 length.
In the present embodiment, drilling rod body 10 long 3m, in other specific embodiment, the length of sliding pin type drilling rod can be processed as required, is generally 2～5m.
As shown in Figure 1, sliding pin type drilling rig and sliding pin type drilling rod are worked as follows:
1) put up drilling cramp 9, rig is in place, opens the turnover panel of mill 300, boring Tapper (not shown) is extend into middle the hole 310 of mill, Tapper is contacted with ground, employing is driven into method Tapper is driven in the soil layer about 0.8m, extract Tapper, the perforate success.
2) drill bit 100 is connected 200 with conventional drilling rod, drill bit 100 is extend into the hole at the bottom of.
