Abstract
The utility model relates to a collector ring. The collector ring can be used for the transmission and conversion of electric current and electric signals on various logging trucks and perforation vehicles, and can be used on other equipment which requires the transmission and conversion of electric signals in the mine sites of geological minerals, petrol and natural gas. An existing collector ring which adopts an open assembly structure has no corrosion resistance and short service life. The utility model is characterized in that an assembly structure is changed into an entirely totally enclosed type, which means that an O-shaped seal ring is used for sealing the site where a housing is connected with an end cover and a tail cover, a gum seal ring is used for sealing the site where a rotating shaft is connected with the end cover, and a double-face sealed bearing is used as a rotating shaft supporting bearing; accordingly, the sealing reliability of the product can be enhanced, and the service life can be extended by from 8 to 12 times.
Description
The utility model is to be applicable to that the electric current of all kinds of well loggings that geological and mineral, petroleum gas, mining site use, perforator truck and signal of telecommunication transmission conversion and other need carry out the collecting ring of electric signal transmission conversion.
The present collecting ring that uses, because that material is selected is improper, sealed construction especially whether, not corrosion-resistant, useful life is very short, and rotating shaft adopts holding screw with being connected of terminal pad, connects that unreliable frequent appearance is loosening to cause the collecting ring inefficacy.
The utility model is primarily aimed at existing collecting ring weak point, to the redesign of collecting ring assembly structure, to reach the purpose that increases the service life.
The utility model project organization is:
Collecting ring, by terminal pad (1), end cap (2), left bearing (4), shell (5), double-screw bolt (6), brush fixed mount (7), bearing pedestal (8), right bearing (9), tail-hood (10), plug screw (11), plug connector (12), brush assembly (13), ring core assembly (14) constitutes, terminal pad (1) is connected with end cap (2), ring core assembly (14) and brush assembly (13) are fixed on the brush fixed mount (7), double-screw bolt (6) links into an integrated entity end cap (2) and tail-hood (10) and forms a cavity, brush fixed mount (7) be fixed in this cavity by rotating shaft and two ends by bearing (4,7) fix, plug connector (12) is fixed on the tail-hood (10) by plug screw (11), housing (5) adopts the O-ring seals sealing with end cap (2) tail-hood (10) joint, rotating shaft and end cap (2) joint adopts the sealing of colloid sealing ring, shaft support bearing (4,7) select the dual face seals bearing for use.Rotating shaft adopts 4 bolts to be connected with terminal pad (1), and locks with steel wire.
Because it is the integral sealing structure, enters collecting ring inside so can prevent corrosive liquids, thereby has prolonged useful life.
The utility model also adopts 4 stainless steel bolts to be connected rotating shaft and terminal pad, and locking with steel wire locking, has prevented the possibility because of connector loose damage collecting ring.
In addition, the used brush section configuration of the utility model is a rectangle, has reached wear-resistant, and contact area is big, allows the purpose by big electric current, voltage.
The utility model advantage is: 1, integral sealing formula structure, prolonged product useful life greatly, and through the evidence of oil reservoir logging car, the life-span is 8～12 times of non-sealed type product.2, contact performance is reliable, and volume is little, allows by electric current the magnitude of voltage height.3, connect reliably, can not become flexible.
Accompanying drawing is the utility model structural representation.
The figure number explanation:
1-terminal pad, 2-end plate, 3-sealing ring
4-left bearing, 5-shell, 6-bolt
7-brush fixed mount, 8-bearing pedestal, 9-right bearing
10-tail-hood, 11-plug screw, 12-plug connector
13-brush assembly, 14-ring core assembly
Embodiment: collecting ring mainly is made up of ring core assembly (14), brush assembly (13), brush fixed mount (7), dual face seals block bearing (4 and 7), end cap (2), tail-hood (10), shell (5), terminal pad (1) and seal (3), plug connector (12) etc., ring core assembly (14) by terminal pad and running cylinder and cylinder on cable be connected, all the other members such as brush assembly are static element, and brush assembly is connected with ground instrument by cable.
Claims (2)
1, a kind of collecting ring, by terminal pad (1), end cap (2), left bearing (4), shell (5), double-screw bolt (6), brush fixed mount (7), bearing pedestal (8), right bearing (9), tail-hood (10), plug screw (11), plug connector (12), brush assembly (13), ring core assembly (14) constitutes, terminal pad (1) is connected with end cap (2), ring core assembly (14) and brush assembly (13) are fixed on the brush fixed mount (7), double-screw bolt (6) links into an integrated entity end cap (2) and tail-hood (10) and forms a cavity, brush fixed mount (7) is fixed by rotating shaft and is positioned at this cavity and two ends by bearing (4,7) fix, plug connector (12) is fixed on the tail-hood (10) by plug screw (11), the utility model is characterised in that housing (5) and end cap (2), tail-hood (10) joint adopts the O-ring seals sealing, rotating shaft and end cap (2) joint adopts the sealing of colloid sealing ring, shaft support bearing (4,7) select the dual face seals bearing for use.
2,, it is characterized in that rotating shaft and terminal pad (1) adopt four bolts to be connected, and lock with steel wire according to the described collecting ring of claim 1.
