Description
Technical field
The present invention relates to drill collar quasi-instrument technical field, more particularly to a kind of locking device of drill collar quasi-instrument.
Background technology
Oil instrument needs to turn on drill collar, the circuit in drill collar quasi-instrument, is in communication with the outside by drill collar end, therefore
A kind of clamping tool is needed, fast clamp drill collar end, realizes reliable be electrically connected.
Existing clamping device includes quoit, locking head and bearing pin, but easily loosens, and influences being electrically connected for drill collar
It is logical.
The content of the invention
The brief overview on the present invention is given below, to provide the basic reason on certain aspects of the invention
Solution.It should be appreciated that this general introduction is not the exhaustive general introduction on the present invention.It is not intended to determine the key of the present invention
Or pith, nor is it intended to limit the scope of the present invention.Its purpose only provides some concepts in simplified form, with
This is as the preamble in greater detail discussed later.
To solve the above problems, the present invention proposes a kind of locking device of drill collar quasi-instrument.
A kind of locking device of drill collar quasi-instrument, including quoit, bearing pin and the quick locking head being equipped with, the gold
Wave groove being machined with category circle, the gap change between the quoit and drill collar is compensated during for locking.
The locking device of drill collar quasi-instrument provided by the invention, it is simple in construction, effectively improve drill collar quasi-instrument locking can
By property.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is a kind of structural representation of embodiment of locking device of drill collar quasi-instrument provided by the invention.
Fig. 2 is that Fig. 1 attempts along cuing open for line A-A.
Fig. 3 is the enlarged drawing of I parts in Fig. 1.
Embodiment
Illustrate embodiments of the invention with reference to the accompanying drawings.Retouched in the accompanying drawing of the present invention or a kind of embodiment
The element and feature that the element and feature stated can be shown in one or more other accompanying drawings or embodiment are combined.
It should be noted that in order to understand purpose, eliminated in accompanying drawing and explanation known to unrelated to the invention, those of ordinary skill in the art
Part and processing expression and description.
With reference to figure 1 and Fig. 2, the present embodiment provides a kind of locking device of drill collar quasi-instrument, including the metal being equipped with
Circle 1, bearing pin 2 and quick locking first 3, wave groove 4 is machined with quoit, compensate between quoit 1 and drill collar 5 during for locking
Gap changes.
Further, wave groove 4 can be in the optional position on quoit, such as wave groove position and quick locking
The line of first 3 position is straight line, so can uniformly compensate the gap change between quoit 1 and drill collar 5.
As a preferred embodiment, the number of wave groove is 2-10.
The locking device of drill collar quasi-instrument provided by the invention, it is simple in construction, effectively improve drill collar quasi-instrument locking can
By property.
Although the present invention and its advantage is described in detail it should be appreciated that without departing from by appended claim
