A kind of top drive cable for well drilling connector
Technical field
Technical field more particularly to a kind of top drive cable for well drilling connector the present invention relates to cable fitting.
Background technology
At present, the drilling well used on oil field generally includes three parts with top drive system, is provided on ground respectively
Ontology and top drive cable are driven in electric-controlled house, the top on derrick.
Top drive cable is divided into as power cable and controls cable two parts, and power cable is used for transmitting power, controls cable
For transmitting signal.Since transmission range is longer, for the ease of installing and transporting, power cable is according to the position for using middle place
It puts, generally requires and be divided into three sections, respectively move about cable, derrick cable and land cable, and signal cable is then divided into two sections.Top
Drive ontology needs reciprocal up and down motion on derrick during the work time, and the one end for the cable that moves about can also follow top to drive ontology fortune
It is dynamic, therefore the cable that moves about, especially the travelling cable near top drive ontology, it can be disconnected because of motion intense, influence work
The reliability of work.
And it due to the Type-Inconsistencies of every section of cable both ends plug, needs to turn back and forth when installing cable, makes cable two
The connector at end matches and then completes installation.And not only very long but also space is little for hoistway installation route, when connecing for cable both ends
When inconsistent, need to exchange cable back and forth.So that in cable resettlement and installation process, being susceptible to setup error causes to return
Work, and then influence working efficiency.
Invention content
The invention is intended to provide a kind of top drive cable for well drilling connector, to solve when drilling well is installed with cable since connector is taken

The principle of this programme is:When cable needs to combine, two cable connectors are arbitrarily chosen.When two cable connectors
During coupling, the guide end of two cable connectors is opposite one by one.Then female connector is slided toward identical direction, at this time one of electricity
The pin end of cable joint stretches out, and the female connector of another cable connector stretches out.Then the pin end of stretching and female connector are plugged together
Get up,.Then the pin end of stretching is rotated so that the lead of pin end is inserted into the pilot hole of female connector.At this point, lead
It is connected with the conducting wire in pilot hole, to realize the coupling of two cables.Finally start position-limit mechanism, the public affairs of stretching are consolidated with this
Connector and female connector are allowed to complete coupling.
The advantages of this programme, is:1st, this programme can be rotated further by pin end and realize arbitrarily by sliding female connector or pin end
The coupling of two cable connectors realizes coupling without specific two cable connectors.Therefore, using the connector hoistway that
Under severe and narrow environment, it is avoided that the unnecessary work such as thread-changing when connector is misfitted.And then the connector can reduce well
The working strength of road staff improves working efficiency.2nd, position-limit mechanism can be passed through after two cable connector couplings in this programme
The relative displacement of the two is limited, therefore, ontology is driven when top drive cable is driven to move up and down in top, and position-limit mechanism is avoided that two electricity
The possibility that cable disconnects, and then improve the reliability of top drive cable work.3rd, the female connector cross section in this programme be triangle, three
The area being had more at a angle at pin end circular cross-section is larger, and increase staff slides focusing surface during cable connector so that
Artificial personnel's more convenient operation, it is easier to.
Further, a kind of top drive cable for well drilling connector according to claim 1, the structure of the position-limit mechanism with
The internal structure for pressing ball pen is identical, and component corresponding with pen core is abutting bar in the position-limit mechanism, the abutting bar
Free end is in contact with pin end.This position-limit mechanism realizes that pushing against bar stretches into stretching, facilitates control so that this connects by pressing
Head operates convenient reliable.
Further, the pin end is equipped with the annular groove stretched into for pushing against bar with pushing against bar contact position.It is straight with pushing against bar
It connects compared with the technology that the smooth outer wall of pin end offsets to realize limiting, this programme is further limited when two connectors couple
Relative displacement so that two connectors combine more firm, and then improve the functional reliability of the connector.
Further, two guide ends adjacent in four guide ends installation lead, another two guide end installation pilot hole.
Compared with two guide ends installation lead laterally or longitudinally, this programme makes two cable connector phase couplings in rotation cable connector
During conjunction, without rotating 90 degree, only rotating 45 degree can complete to plug together.The angle of rotation becomes smaller so that connector drives cable to turn round
The angle turned ensures that cable will not be twisted off without too big, and Elongated cable wire uses duration, and then plays saving fortune
The effect of row cost.
Further, the female connector inner wall is to be equipped at intervals with four limited blocks with 45 degree.45 degree of spaced limited blocks,
Blindness is rotated such that lead is combined with pilot hole when avoiding two connectors from being coupled, with the side of limited block limitation rotation
Position so that be more convenient during using the connector.
