Abstract
The utility model discloses an automatic spinner for petroleum drilling, which comprises a pedestal upright assembly (1), a telescopic arm assembly (2), a big clamp assembly (3), a spinner assembly (4) and a hydraulic electric control assembly (5), wherein the spinner assembly (4) comprises an upper clamp body (4a) and a lower clamp body (4b), the automatic spinner is characterized in that a round slide track (6) and a bearing (7) are arranged between the upper clamp body (4a) and the lower clamp body (4b). According to the utility model, the round slide track and the bearing are arranged between the upper clamp body and the lower clamp body, so that the upper clamp body and the lower clamp body can be relatively rotated around the centre of an opening of the clamp body, elastic alignment and precise location can be realized, a drill rod is protected, and the operating quality is improved.
Description
Technical field
This is practical to relate to a kind of oil drilling device, and a kind of oil drilling that relates to that is specifically related to is used spinner.
Background technology
Spinner is one of visual plant in the modern drilling well, can accomplish the spinner connection work of drilling tools such as drilling rod, sleeve pipe.It extensively is matched in land, marine advanced oil-well rig, rise, in the going down process, to drilling tool (drilling rod, drill collar, sleeve pipe and various joint) go up, shackle and quick spinner operation.At present, comparatively commonly used is the traveling-type hydraulic tong.Not enough below but it exists: the one, under identical running parameter, structure is huger, and is not compact; The 2nd, tong assembly and spinner assembly center misalign in the course of the work, cause in the spinner process drilling rod is produced moment of flexure, thereby easily drilling rod is caused damage; The 3rd, in the telescopic arm traction tong assembly motion process, the orientation angle of tong and height and position are difficult to accurate assurance.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, provides a kind of improved oil drilling to use spinner, and its compact conformation can elasticity centering and accurate location.
For reaching above-mentioned purpose; The utility model is taked following technical scheme; The utility model comprises: pedestal columns assemblies, telescopic arm assembly, tong assembly, spinner assembly, hydraulic pressure electric controling assembly; The spinner assembly comprises upper clamp and lower clamp, it is characterized in that: circular slideway and bearing are installed between upper clamp and lower clamp.
The utility model is taked technique scheme, has following beneficial effect: the utility model is equipped with circular slideway and bearing between upper clamp and lower clamp, and purpose is that the satisfied lower clamp of going up can relatively rotate around the center of caliper opening.Lower clamp is static relatively, and upper clamp is done the rotation with respect to lower clamp through stretching of moment of torsion oil cylinder.One end of moment of torsion oil cylinder is connected on the lower clamp, and the other end is connected on the upper clamp.The stroke of moment of torsion oil cylinder requires to satisfy the requirement of the minimum relative rotation of going up lower clamp; After the installation site of the geometric parameter of last lower clamp and moment of torsion oil cylinder is confirmed; There are a kind of linear functional relation in the stroke of oil cylinder and the relative rotation of last lower clamp, thereby lower clamp can be relatively rotated around the center of caliper opening accurately.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.
Fig. 1 is the structure diagram of the utility model embodiment.
Fig. 2 is a spinner modular construction sketch among the utility model embodiment.
Identify among the figure: 1-pedestal columns assemblies, 2-telescopic arm assembly, 3-tong assembly, 4-spinner assembly, 4a-upper clamp, 4b-lower clamp, 5-hydraulic pressure electric controling assembly, 6-slideway, 7-bearing.
The specific embodiment
Like Fig. 1, shown in Figure 2; The utility model comprises: pedestal columns assemblies 1, telescopic arm assembly 2, tong assembly 3, spinner assembly 4, hydraulic pressure electric controling assembly 5; Spinner assembly 4 comprises upper clamp 4a and lower clamp 4b, it is characterized in that: circular slideway 6 and bearing 7 are installed between upper clamp 4a and lower clamp 4b.The bearing 7 that the utility model adopts can also adopt roller to replace.
