Description

A kind of multi-functional selector that automatically resets

Technical field:

The utility model relates to a kind of corer control device for the oil well logging coring operation, belongs to the petroleum well logging technology class.

Background technology:

Coring operation is the important step in the oil well logging operation process, the core component in the corer that uses when selector is coring operation, and corer is finished gearshift function by selector.At present, on-the-spot normally used corer selector has machinery and electronics two large classes.The machinery selector can be divided into step-by-step movement and rotary two classes of motor: the step-by-step movement selector is to carve 36 contact points at the disk of a copper clad laminate system, disk is fixed, contact with 36 contacts respectively after the idler axle rotation, idler axle is driven by electromagnetic relay, every energising once, the actuating of relay once, angle of axle rotation, selector just changes a gear, and the mandrel of this selector is fixing too tight, the relay band is motionless, fixing too pine then axle is easily skidded, and the card shelves occur, when axle when rotating, because shelves or the not first-class problem of contact very easily appear connecting in the angle accumulated error; The rotary selector of motor is 36 contacts of nonmetallic ring embedding an annular, each contact is with also having a gear contact on the angle, when electric machine rotation, gauge outfit has indication on contact position ground, be designated as zero in noncontact point position, determine whether stopping gearshift by seeing the gauge outfit indication, this kind selector can only be used for manually control, be not suitable for automatic control, and this kind selector can not make up.Electronic selector is to utilize electronic signal control controllable silicon to realize break-make, and controllable silicon is electronic product, might be bad, if the direct conducting of controllable silicon, very easily an ignition point is logical more than two or two, easily causes security incident.

The utility model content:

The multi-functional selector that automatically resets that the purpose of this utility model is to provide a kind of one-time success rate of can increasing work efficiency and core, gets rid of unsafe factor.

The purpose of this utility model is to realize like this.This kind selector is comprised of 26 core aviation plugs, ignition transformer, skeleton, control circuit, gearshift assembly, 45 core sockets, its structure assembled relation is as follows: the skeleton upper and lower end is respectively equipped with 26 core aviation plugs and 45 core sockets, the skeleton lower inside is provided with the gearshift assembly, and its top is provided with ignition transformer and control circuit; Aviation plug links to each other with each parts in the skeleton by higher temperature line, the 1-36 core access gearshift assembly of 45 core plugs, and 41,42,43,44 cores connect respectively 1,2,6,7 cores of 26 core aviation plugs, 45 core Access Control circuits; Wiring point on the gearshift assembly is connected with ignition transformer with control circuit by higher temperature line, and control circuit links to each other with 26 core aviation plugs by higher temperature line.Wherein, the gearshift assembly is comprised of electric rotating machine, motor fixing seat, turning cylinder, contact stationary magazine creel, conducting rod, spring, rotating shaft base, and its assembling mode is as follows: conducting rod and spring are packed in each eyelet of turning cylinder, use the pressing plate pressing spring; Turning cylinder is inserted in the stationary magazine creel of contact, adjust the position of turning cylinder, load onto rotating shaft base; Electric rotating machine is installed on the motor fixing seat, then motor fixing seat is inserted the contact stationary magazine creel, and fixed after adjusting the position.Control circuit is comprised of the many cable hearts and electronic devices and components, and its operating principle is as follows: the 2# cable heart provides power supply for control circuit, through D ₀By C ₁, D ₁, C ₂, C ₃Voltage regulation filtering, the working power of generation+8V is Vcc.When the 2# cable heart began to power, Vcc was through C ₇And R ₇Produce one by high level to low level change procedure, after IC5F, IC5F, IC5D shaping, export one by the triggering signal of low level to high level by 8 pin of IC5D, this triggering signal is input to 3 pin of IC3A, at this moment 1 pin of FC3A output high level, high level is input to 3 pin of IC4A, and high level of 1 pin output of IC4A is through R _9-1Take rear drive as metal-oxide-semiconductor N ₂Conducting, at this moment motor M ₁Rotate, after first grade of turning cylinder conducting rod contact, signal of gearshift assembly output resets IC3A, and namely 1 pin of IC3A is output as zero, and at this moment motor stops operating, and this process is the process of automatically reseting.After first igniting finished, come a negative pulse on the 2# cable core, after undersuing process IC1 and the R3, send into the IC2A4 pin, at this moment 6 pin of IC2A produce a positive pulse, and positive pulse width is by R ₄, C ₅Determine.The positive pulse of IC2A6 pin is sent into 11 pin of IC3B, and at this moment 13 pin of IC3B are output as high level, and high level is through IC4C and R _6-1Rear drive N ₁Conducting, electric machine rotation, when the conducting rod of turning cylinder was connected second gear, the gearshift assembly produced a signal, made high level of 1 pin output of IC6, behind this high level process IC5B and the IC5C, be input to 12 pin of IC2B, make positive pulse of 10 pin output of IC2B, this positive pulse makes the 13 pin output of IC3B become low level, thereby make the N1 cut-off, motor stops operating.With this cycling, until after the conducting rod on the turning cylinder connected 0 grade, gearshift assembly output signal made low level of 8 pin output of IC4B, thereby controls a top corer job through IC5A and IC4B, this corer quits work.The gearshift assembly course of work is as follows: when electrical power, the driven by motor turning cylinder rotates, and turning cylinder band moving conductive rod contacts with each contact on the stationary magazine creel of contact, thereby finishes gearshift; The 12V AC power is received on each contact of igniting gear through 2 conducting rods on the some fire ring, thereby finishes igniting; Gear shows to encircle by two conducting rods to be received respectively on each contact of gear demonstration, finishes gear and shows; Signal on the signal source is received gearshift through each conducting rod and is stopped contact, gearshift control contact, resets and select on the rifle control contact, and these signals are delivered in the control circuit, finish gearshift control.

The utility model organically combines digital circuit and mechanical device, make it the control function of existing electronic selector, the safety factor that mechanical selector is arranged again, branched selector can also be concatenated into simultaneously together and use, it is compared with old-fashioned selector and has the following advantages: 1. have combination function, can branched selector serial connection use; 2. has the gear Presentation Function; 3. has the cartridge bag test function; 4. control is simple, can manually control also and can automatically control; 5. the debugging maintenance is convenient, does not need special installation and instrument; 6. circuit is simple and reliable, and anti-seismic performance is good.
