Description
Technical field
The present invention relates to a kind of rotary drilling rig to press casing device, the burial and construction field for casing.
Background technology
It is at present cast-in-situ bored pile in the foundation construction stage of extra-high voltage grid construction, conventional use of foundation working process
Foundation working process, it possesses the advantages that mechanization degree is high, speed of application is fast, safe and reliable.Applied carrying out cast-in-situ bored pile
Man-hour carries out boring work commonly using rotary drilling rig, during drilling in order to prevent aperture from caving in, it is necessary to embedded diameter than hole footpath slightly
Greatly, the casing of buried depth 2-4 rice is protected, and its operating procedure is generally：First drilled before embedded casing, bore diameter is slightly less than shield
Cylinder diameter, can so make to produce frictional resistance between hole wall and casing, then casing is depressed into hole using instrument.
Typically using under casing under vibration hammer or power drill/driver when currently used rotary drilling rig is buried to casing
Casing, on the one hand there is the defects of complicated, equipment cost is high in such instrument, on the other hand due to vibration power during embedded casing
Or rotating friction force between power drill/driver and casing, casing and pressing casing device can be caused to damage.
The content of the invention
The technical problem to be solved in the invention is to provide a kind of rotary drilling rig pressing casing device, can reduce embedded shield
To the damaged condition of casing and press device during cylinder, and the structure of the present invention is simple, flexible and convenient to use.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
A kind of rotary drilling rig presses casing device, including the drilling rod being connected with rotary drilling rig, is fixedly connected in drilling rod lower end
Part, the connector lower end are provided with several by pressure arm and are fixedly connected on platen by pressure arm lower end, the platen bag
Fixed platen and rotary platen are included, is connected between rotary platen and fixed platen by needle roller, needle bearing is formed, is rotating
Platen lower surface opens up concentric ring recesses.
Further, the concentric ring recesses quantity is multiple.
Further, the pressure arm of pressing is trapezoidal.
Further, it is described trapezoidal to be at least 3 by pressure arm quantity.
Further, symmetrical four pin shaft holes, the drilling rod with rotary drilling rig on the same circumference of connector outer wall
It is fixedly connected by bearing pin.
Further, it is described to be connected by screw bolts by between pressure arm and platen.
The press device of casing is attached by the present invention with rotary digging driver drilling rod, is applied using the moment of torsion of rotary drilling rig to casing
Add a pressure, it is overcome the frictional force between soil, casing is smoothly transferred to specified location, this process due to by
Pressure device by relative turn between pressure arm and casing be present, can cause to damage to the edge of casing and by pressure arm, this hair
It is bright that further improvement has been done to press device, in by being fixedly connected with platen under pressure arm, platen include fixed platen and
Rotary platen, connected between rotary platen and fixed platen by needle roller, form needle bearing, opened up in rotary platen lower surface
Concentric ring recesses, casing is positioned in annular groove, such drilling rod is delivered to active force on press device and is converted into downwards
Pressure, eliminate the relative force of sliding friction between press device and casing, reduce the frictionally damage to both, and the present invention
Possesses the advantage such as simple in construction, detachable, flexible and convenient to use.

Embodiment
The present invention is described in further details with specific embodiment below in conjunction with the accompanying drawings：
A kind of rotary drilling rig presses casing device, as shown in Figure 1 and Figure 2, including drilling rod, connector, several by pressure arm with
And by the platen being fixedly connected under pressure arm, platen includes fixed platen and rotary platen, between rotary platen and fixed platen
Connected by needle roller, form needle bearing, concentric ring recesses are opened up in rotary platen lower surface, as shown in figure 3, platen simultaneously
The fixed relative space position by pressure arm, and stiffening device bulk strength can be played, is prevented by pressure arm stress deformation, by pressure arm
It is bolted to connection between platen, while the distribution map of built-in needle roller is as shown in Figure 4；The top of drilling rod is connected into rotary digging
Rig, the bottom of drilling rod are fixedly connected by bearing pin with connector, uniform four pin shaft holes on the same circumference of connector outer wall, are led to
Cross bearing pin the drilling rod of rotary drilling rig is connected with connector with being used cooperatively for pin shaft hole, connector lower end is fixedly connected with 4
It is trapezoidal to press pressure arm.
Operation principle：
Required according to site construction technology, stake position center is released using total powerstation, excavated casing foundation ditch with excavator, will protect
Cylinder is placed on the position of technological requirement, and the press device of casing is positioned at the top of casing, make the annular groove of press device with
The inside and outside wall of casing is tangent, is used cooperatively by bearing pin and connector outer wall upper pin hole by the drilling rod and connector of rotary drilling rig
It is connected, starts rotary drilling rig and drive drilling rod to move downward, applies one to pressing casing device using the moment of torsion of rotary drilling rig
Pressure, it is overcome the frictional force between soil, casing is smoothly transferred to specified location, in by being fixedly connected under pressure arm
Platen, platen include fixed platen and rotary platen, connected between rotary platen and fixed platen by needle roller, form rolling
Needle bearing, concentric ring recesses are opened up in rotary platen lower surface, casing is positioned in annular groove, so protected by pressing
Wound packages puts the simply downward active force being delivered at the top of casing, eliminates rotation stress, and then has both eliminated installation pressing
Relative force of sliding friction between device and casing, reduces the frictionally damage to both, can also prevent the center of casing from sending out
Raw skew, and the present invention possesses the advantage such as simple in construction, detachable, flexible and convenient to use.In order to expand the application model of the present apparatus
Enclose, multiple grooves are set on platen, so go for the construction of various sizes of casing.
