Abstract
The utility model discloses a simple drill rod clamping device. The simple drill rod clamping device comprises a device main body, wherein the device main body is a hollow cylinder; a plurality of hydraulic cylinders are fixed on the device main body along the diameter direction of the device body; and piston rods of the hydraulic cylinders are toward the circle center of the device main body. The simple drill rod clamping device has the advantage of simple structure, and raw materials of a drill rod can be clamped, so that the machining operation of the drill rod by persons is facilitated.
Description
Technical field
The utility model relates to a kind of pipe fitting cramping arrangement, relates in particular a kind of easy device that is used for drill-rod clamping.
Background technology
Drilling rod is that afterbody is with the steel pipe of a chain for binding criminals line, for connecting the rig landscape apparatus and being positioned at drilling well bottom brill mill equipment or bottom outlet device.The purposes of drilling rod is that drilling mud is transported to drill bit, and improves, reduces together with drill bit or rotate the bottom outlet device.Drilling rod must be able to bear huge interior external pressure, distortion, bending and vibration.When making oil drill rocker, the drilling rod lines need to be made, to meet the instructions for use of drilling rod on the raw material of making drilling rod.The raw material of making drilling rod are cylindrical, and drilling rod is generally all very long, and processing and fabricating is very inconvenient.
The utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of simple and easy drill-rod clamping device is provided, and this apparatus structure is simple, the drilling rod raw material can be clamped, and helps personnel to the process operation of drilling rod.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of simple and easy drill-rod clamping device, it comprises apparatus main body, and described apparatus main body is hollow cylinder, and is fixed with a plurality of hydraulic cylinders along its diametric(al) on apparatus main body, and the piston rod of described hydraulic cylinder is towards the center of circle of apparatus main body.
Be used for placing drilling rod in the hollow cylinder of apparatus main body of the present utility model, the hydraulic cylinder on device is used for drill-rod clamping, so that drilling rod is carried out process operation.
Further technical scheme is:
Preferably, include air inlet and exhaust outlet on described hydraulic cylinder, described air inlet and exhaust outlet are arranged on the end away from apparatus main body.
Hydraulic cylinder of the present utility model is used for regulating it with drill-rod clamping, when operation, closes exhaust outlet, opens air inlet, and the piston rod of hydraulic cylinder just can be with drill-rod clamping.Operation is completed, and opens exhaust outlet, closes air inlet, and the piston rod of hydraulic cylinder just can move to the direction away from drilling rod, at this moment, takes off drilling rod and gets final product.
Preferably, described hydraulic cylinder has two at least.
Preferably, the air inlet on described hydraulic cylinder is connected in same admission line, and the exhaust outlet on hydraulic cylinder is connected in same discharge duct.
The air inlet of hydraulic cylinder of the present utility model is connected in same admission line, and during with drill-rod clamping, admission line acts on air inlet simultaneously when needs, makes the piston rod of hydraulic cylinder mobile with drill-rod clamping simultaneously.The exhaust outlet of hydraulic cylinder is connected in same discharge duct, and when needs unclamped drilling rod, discharge duct acted on exhaust outlet simultaneously, makes the piston rod of hydraulic cylinder simultaneously to moving away from the drilling rod direction.
Preferably, described hydraulic cylinder is positioned on the same cross section of apparatus main body and hydraulic cylinder is symmetrically distributed with the center of circle of apparatus main body.
Hydraulic cylinder of the present utility model is positioned on the same cross section of apparatus main body, and with drill-rod clamping the time, piston rod is positioned on the same cross section of drilling rod when the piston rod of hydraulic cylinder, has guaranteed to clamp the degree of stability of bull stick.
Preferably, described apparatus main body is fixed on bracing frame.
In the middle of the operation of reality, in order to be fit to personnel's operation, apparatus main body will be positioned at certain height.Apparatus main body is fixed on bracing frame, further is fit to personnel's operation.
Compared with prior art, the beneficial effects of the utility model are:
1, apparatus main body of the present utility model is used for placing the bull stick that needs processing, and primer fluid cylinder pressure, the piston rod of hydraulic cylinder just can be regulated to coordinate bull stick is clamped, so that operating personnel are to the operation of drilling rod.
2, of the present utility model simple in structure, be convenient to make simple operation.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Label in figure is: 1, bracing frame; 2, apparatus main body; 3, air inlet; 4, exhaust outlet; 5, hydraulic cylinder.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Embodiment of the present utility model includes but not limited to the following example.
[embodiment]
A kind of simple and easy drill-rod clamping device as shown in Figure 1, it comprises apparatus main body 2, and described apparatus main body 2 is hollow cylinder, and is fixed with a plurality of hydraulic cylinders 5 along its diametric(al) on apparatus main body 2, and the piston rod of described hydraulic cylinder 5 is towards the center of circle of apparatus main body 2.
Include air inlet 3 and exhaust outlet 4 on described hydraulic cylinder 5, described air inlet 3 and exhaust outlet 4 are arranged on the end away from apparatus main body 2.
Described hydraulic cylinder 5 has two at least.
Described hydraulic cylinder 5 is positioned on the same cross section of apparatus main body 2 and hydraulic cylinder 5 is symmetrically distributed with the center of circle of apparatus main body 2.
Described apparatus main body 2 is fixed on bracing frame 1.
Be as mentioned above embodiment of the present utility model.The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
