Abstract
The utility model discloses a closed combined wiring structure of a well wall coring device, and relates to a well wall coring device. The connection of 36 ignition screws and fuses of the 36 ignition screws can be carried out in closed wire-passing holes. The structure of the closed combining and wiring structure of the well wall coring device is characterized in that long holes arranged on the portions where lug plates are assembled on the 36 ignition screws in communicating mode, and are used as the wire passing holes, and assembly holes of the ignition screws are communicated with the wire passing holes. The lug plates of 36 fuses are installed one by one, the 36 lug plates provided with the fuses and specially manufactured nuts are respectively assembled in 36 insulation sleeves, the lug plates are arranged on the upper portions of insulation sleeves, and the specially manufactured nuts are arranged on the lower portions of the insulation sleeves. The lug plate and the nut of each leading wire are fixed according to the assembling position of the 36 ignition screws and are assembled to a whole with each leading wire. Then the whole structure is arranged on the wire passing holes, the ignition screws and the nuts are screwed up in sequence, and the connection of the 36 ignition screws and the fuses are accomplished. The connection of the 36 ignition screws and the fuses in the closed wire passing holes is achieved, and the wire connecting holes do not need to be sealed any longer.
Description
Technical field
The utility model relates to a kind of well bore sidewall core taker.
Background technology
At present, 36 of the well bore sidewall core takers screw of igniting with the structure that its lead-in wire is connected is: as wiring hole, have aperture to communicate between wiring hole side processing through wires hole, through wires hole and wiring hole at position circular hole of processing of each ignite screw assembling lug plate, nut.36 lead-in wires through wires hole of packing into during assembling, every lead-in wire enters respectively corresponding wiring hole through aperture, and lead-in wire is installed after the lug plate in wiring hole and is ignited the screw nut screwing clamping, wiring hole is sealed after the connection again.During use, wiring hole has sealing hidden danger and increases difficulty of processing, raising manufacturing cost in oil well mud.
The utility model content
Seal hidden danger and difficulty of processing is large, manufacturing cost the is high problem of sealing that produce for solving ignite screw and need butted line hole after its lead-in wire is connected of well bore sidewall core taker.The utility model provides a kind of well bore sidewall core taker closed combination wiring construction, the lug plate of 36 lead-in wires, nut assemble with the screw of igniting in airtight through wires hole, the realization screw of igniting is connected with its lead-in wire, replace the wiring hole syndeton, can eliminate sealing hidden danger, reduce difficulty of processing, reduce manufacturing cost.
For achieving the above object, by the following technical solutions:
A kind of well bore sidewall core taker closed combination wiring construction is installed lug plate and the through wires holes of packing into 36 lead-in wires of 36 screws of igniting of well bore sidewall core taker, and each screw of igniting tightens together with the lug plate of nut and lead-in wire.Through wires hole is to be positioned at the airtight slotted hole that connects 36 screw assembling lug plate positions of igniting, the lug plate of every lead-in wire and the position of nut are fixed according to the rigging position of 36 screws of igniting and are dressed up an integral body with lead wire set, then the through wires hole of packing into just realizes that with nut screwing clamping 36 screws of igniting are connected with lead-in wire to the screw of igniting successively.
The beneficial effects of the utility model are:
Replace wiring hole with airtight through wires hole, eliminate wiring hole sealing hidden danger, reduce difficulty of processing and manufacturing cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the structure sectional view of the examples of implementation of utility model.
Fig. 2 is that sectional view is looked on the left side of examples of implementation.
1 well bore sidewall core taker in the drawings, the screw of 2. igniting, 3. terminal plate, 4. lead-in wire, 5. lug plate, 6. insulation sleeve, 7. special nut, 8. ply-yarn drill 9. panels, 10. screw, 11. nuts
The specific embodiment
In Fig. 1, in well bore sidewall core taker 1, at the ignite position processing elongated slot of screw 2 assembling lug plates 5 and with panel 9 welded seals, as through wires hole of perforation.
Processing special nut 7, its shape are circular and the band square key.Processing insulation sleeve 6, endoporus cornice keyway.To go between and 4 lug plates 5 are installed, lug plate 5 and the special nut 7 that then will install behind the lead-in wire 4 are assembled in insulation sleeve 6 holes, and special nut is below in the above for lug plate.
Hole at the rigging position according to the screw 2 of igniting on the terminal plate 3. and the rigging position that the insulation sleeve 6 after the assembling is aimed at the screw 2 of igniting according to special nut 7 is fixed on the terminal plate 3 with screw 10, nut 11.
Finish the lead-in wire assembling of other 35 screws of igniting with identical method, then with 36 ply-yarn drills 8 36 lead-in wires are fixed on the terminal plate 3.Namely finish the terminal plate assembling.
With the terminal plate through wires hole of packing into after the assembling, adjust the terminal plate position, make 36 special nuts aim at the screw rigging position of igniting, the pilot hole of screw of igniting communicates with through wires hole, then 36 ignite screw one by one with insulation sleeve in special nut tighten, finish 36 screws of igniting and be connected with its lead-in wire.
For clear, in Fig. 1, represent two screw lead-in wire wiring constructions of igniting.
[0018] in Fig. 2, is illustrated in after the left apparent place of well bore sidewall core taker 1 through wires hole and the 36 lead-in wire assemblings with the fastening left pseudosection of ply-yarn drill 8.
Claims (3)
1. a well bore sidewall core taker closed makes up wiring construction, 36 lead-in wires of 36 screws of igniting of well bore sidewall core taker are installed lug plate and the through wires hole of packing into, each screw of igniting tightens together with the lug plate of nut and lead-in wire, it is characterized in that: through wires hole is to be positioned at the airtight slotted hole that connects 36 screw assembling lug plate positions of igniting, the lug plate of every lead-in wire and the position of nut are fixed according to the rigging position of 36 screws of igniting and are dressed up an integral body with lead wire set, then the through wires hole of packing into just realizes that with nut screwing clamping 36 screws of igniting are connected with lead-in wire to the screw of igniting successively.
