Description
Affiliated field
The utility model relates to the petroleum well logging technology field, is a kind of signal between the logging winch rotating mechanism, accurate power transmitting device of current delivery of being used for.
Background technology
In the well logging process, the signal of telecommunication that rotates on the cable need be transferred on the logger, the equipment of finishing this task is collecting ring.Traditional logging winch collecting ring complex structure, dustproof, waterproof, moisture effect are poor, and application life is short, reliability and stability are all relatively poor, influences the transmission of the signal of telecommunication.Keep being communicated with well between cable core and ground instrument, resistance is constant; Keep the good insulation performance between the insulating element, just can finish logging tasks.The well logging work progress often will be worked continuously tens hours even tens hours, and condition of work is more abominable.Often take place because of logging winch collecting ring generation problem, need repairing or change collecting ring.The performance of collecting ring directly influences normally carrying out of logging operation, influence well logging result's accuracy.The collecting ring reliability and stability have influenced the continuity of construction and constructor's labour intensity to a great extent.
Summary of the invention
The purpose of this utility model is: a kind of logging winch collecting ring is provided, makes collecting ring can finish the signal between the logging winch rotating mechanism, the transmission of electric current; Have compact conformation, shorten length, and prolong its maintenance period, improve dependability.
The technical solution adopted in the utility model is: the logging winch collecting ring is made of terminal plate, probe, precision bearing and contact ring.Axle has precision bearing to support with the two ends of terminal plate.Be with the contact ring on the axle main body, between each contact ring the felt pad insulation arranged.Insulation is paid somebody's debt and expected repayment later and will be made insulation between contact ring and the axle.The lateral surface of contact ring has annular recess.Each contact ring is all to there being a probe to be in contact with it, and probe is close in the groove of contact ring by elasticity.On the other end link plate of probe.Cover plate is by the upper end of screw at terminal plate, and axle places in the terminal plate.
The groove cross section that the contact ring adopts can be a circular arc, can be V-arrangement or rectangle.With the circular groove is best.
With the electric installation of contact loop contacts be the probe that AuNi9 makes.
Be with 8 contact rings on the axle main body, be fixed with 8 corresponding probes on the terminal plate, 8 wiring points or aperture are arranged on the terminal plate.
During work, axle rotates, and precision bearing rotates, but does not influence terminal plate.Probe all the time in the contact environmental protection hold contact condition.Between each contact ring felt pad is arranged, keep mutually insulated, also guarantee insulation with axle.The aperture that the probe correspondence is arranged on the terminal plate, probe is by aperture corresponding on the terminal plate, and corresponding connection with logging cable reaches signal transmission and current delivery in the rotation.
The contact ring is through vacuum pressure casting epoxy resin batching, processes after the hot setting moulding.The contact ring adopts the moulding of indent formula, and the surface is through gold-plated processing.Probe contacts with corresponding annular groove, transmits signal and electric current so as to the elastic pressure and the annular groove sliding-contact of probe.
The beneficial effects of the utility model: the logging winch collecting ring can be finished the signal between the logging winch rotating mechanism, the transmission of electric current.And transmit signal of telecommunication precision height, big, the stable performance of electric current; Have the advantages that compact conformation, volume are little, in light weight, the life-span is long, prolong winch collecting ring maintenance period, improve dependability.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
