Abstract

The utility model discloses a guide rail type adjustable centering disc for a coal bed gas drilling machine, wherein a centering disc body is arranged in a guide rail in horizontal arrangement, the guide rail is fixedly connected onto a machine frame of a drilling table of the drilling machine, and a regulating device used for tightly pressing the centering disc body is arranged on the machine frame of the drilling machine. When the centering disc adopting the guide rail structure is adopted, the centering disc and a top driving device can be enabled to be vertical to one line, the clamping incapability by a clamp slip caused by drilling rod inclination is avoided, the centering difficulty of a well frame and the drilling table is reduced, and the assembly efficiency is improved.

Description

The guide tracked adjustable centering disk of a kind of coal bed gas drilling machine
Technical field
The utility model patent relates to the technical field of coal bed gas drilling machine rig tool, and specifically top-drive device and rig floor well head regulate the guide tracked adjustable centering disk of a kind of coal bed gas drilling machine of centering.
Background technology
Before drilling well, first ship type base, rig floor to be put and put in place, then rig is left on ship type base, derrick telescoping again, fixing and top-drive device and rig floor pithead position adjusted derrick and rig floor, make top-drive device and centering disk be straight line position, guarantee straight line.This just requires drill truck will reach assigned address, and all around is all suitable, and practical operation is very difficult; Top-drive device and centering disk need position in alignment, guarantee straight line, and because the geological conditions such as drive on top, tire pressure, rig load all have impact to it, therefore can cause cannot centering, unusual trouble in practical operation, and efficiency of assembling is low.
Summary of the invention
The purpose of this utility model is to provide the guide tracked adjustable centering disk of a kind of coal bed gas drilling machine, this centering disk acts on drilling floor surface, derrick drops on drilling floor surface well head, can realize horizontal cross regulates, guarantee on a top-drive device line vertical with centering disk, and do not affect table top other operation and the structural strength of centering disk.
For achieving the above object, technical solutions of the utility model are: the guide tracked adjustable centering disk of a kind of coal bed gas drilling machine, comprise centering disk body, it is characterized in that: described centering disk body is arranged in horizontally disposed guide rail, described guide rail is fixedly connected in drill floor frame, and borer frame is provided with for compressing the adjusting device of centering disk body.
Technique scheme middle guide is mainly used in the strength of bearing mobile centering disk body and the core of feeling relieved be should bear, and can be along the position of guide rail direction lateral adjustments centering disk body.Adjusting bolt, be mainly used in by spanner centering disk left and right fine setting, and pin and do not allow it slide, realized the distance adjustment of centering disk body, and can locate.Beneficial effect of the present invention is:
1, adopt the centering disk of this guide rail structure, can guarantee a centering disk line vertical with top-drive device, keep away drilling rod and inclination, slips adds to be held incessantly.
2, reduce the difficulty of derrick and rig floor centering, improve efficiency of assembling.
3, bolt adjustment structure regulates guide rail centering disk less to its structure influence degree.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
The specific embodiment
The guide tracked adjustable centering disk of a kind of coal bed gas drilling machine as shown in Figure 1, 2, there is centering disk body 3, described centering disk body is arranged in the guide rail 1 of horizontally set, described guide rail is fixedly connected on borer frame 4, borer frame is provided with for compressing the adjusting device 2 of centering disk body, described adjusting device is a hold-down bolt, and hold-down bolt screws on borer frame, and it compresses end and heads on centering disk body 3.
