Abstract
The utility model provides a logging winch collector ring, which is used for logging winch vehicles in the process of petroleum exploration and exploitation. The utility model comprises a base (1), wherein, a main shaft (3) is arranged in the base, a shield ring (12) is installed outside the main shaft, a garland (13) is arranged on the shield ring, a carbon brush (17) is arranged outside the garland, the garland is connected with the binding post (15) at the upper part of the main shaft by a conducting wire, and a protecting cover (10) is also arranged on the base. The collector ring is capable of switching the signals on a logging cable to a fixed logging device while the logging cable is rotating. The utility model has the advantages of small contact resistance of the carbon brush, dustproof, waterproof and damp-proof properties and long service life.
Description
The utility model provides on the logging winch in a kind of oil exploration, the exploitation, is used for the signal of telecommunication with logging cable and is transferred to equipment on the logger.
In the well logging process, the signal of telecommunication on the logging cable in rotating need be transferred on the outside logger, the equipment of finishing this task is called collecting ring.Existing collecting ring complex structure, dustproof, waterproof, moisture effect are poor, and application life is short, often maintenance, changes the accuracy that collecting ring directly influences normally the carrying out of logging operation and the result that logs well.
The purpose of this utility model provides a kind of improved logging winch collecting ring, to improve its application life.
The utility model is to realize like this, on this collecting ring, base is arranged, main shaft is installed in the base, and the main shaft middle part is equipped with the garland axle sleeve, and the garland axle sleeve is equipped with shading ring outward, garland is installed on the shading ring, the carbon brush that is fixed on the carbon brush support contacts with garland, and the prap that is installed on the patchboard of main shaft upper end links to each other with each garland by lead respectively, distinguishes porose on the hole seat on base and the base, also porose respectively in the middle of joint and the main shaft, also have guard shield on the base.
Adopt the collecting ring of said structure, the carbon brush contact resistance is little, dustproof, waterproof, protection against the tide, long service life.
Below in conjunction with description of drawings concrete structure of the present utility model and operating principle.
Fig. 1 is the sectional view of the utility model structure.Fig. 2 is its A-A sectional drawing.Fig. 3 is its B-B sectional drawing.
As shown in drawings, base (1) is arranged on the logging winch collecting ring of the utility model, by bearing (8) main shaft (3) is installed in the base, the main shaft bottom is fixed with joint (2), the main shaft middle part is equipped with garland axle sleeve (11), the garland axle sleeve is equipped with shading ring (12) outward, garland (13) is installed on the shading ring, the carbon brush (17) that is fixed on the carbon brush support (25) contacts with garland, be fixed with guide card (16) on the carbon brush, the prap (15) that is installed on the patchboard (14) of main shaft upper end links to each other with each garland by lead respectively, hole seat (6) on base and the base is gone up porose (5) and hole (7) respectively, in the middle of joint and the main shaft also porose respectively (23), hole (19) also is equipped with guard shield (10) on the base.
Gland (22) and gland (21) are arranged respectively on the main shaft (3) on bearing (8) both sides, sealing ring (4), sealing ring (20) are arranged respectively in the gland.Entering of mud, moisture content etc. be can prevent like this, dustproof, the waterproof effect of application life of bearing and whole collecting ring and well logging result's accuracy improved.
During use, logging cable enters in the collecting ring by hole (23), (19) in the middle of joint (2) and the main shaft (3), and the end on the logging cable is stuck on the cable block (18), and each the end of a thread of logging cable is connected on each prap.Also have cable to enter in the collecting ring by the hole on base (1) and the hole seat (6) in addition, each the end of a thread of this cable is connected on respectively on each guide card (16) that is fixed together with carbon brush.
Because each prap and each garland link together, therefore, the signal of telecommunication on the logging cable that is rotating with main shaft is just through prap, lead, garland, be sent on the carbon brush that contacts, rubs with garland, guide card on carbon brush is sent on the cable in the hole of base, hole seat again, deliver on the various loggers through cable again, finish that the signal of telecommunication on the logging cable in rotating is transferred to task on the logger.
Joint is fixed together by screw (24) and drilling rod, and main shaft rotates with drilling rod, and each garland, shading ring and patchboard, prap rotate with main shaft.
Carbon brush tightly is attached on the garland by carbon brush support (25) and extension spring (26).Can reduce the carbon brush contact resistance like this.
Back-up ring (9) can be arranged between bearing.
Claims (2)
1, the logging winch collecting ring, it is characterized in that, it has base (1), by bearing (8) main shaft (3) is installed in the base, the main shaft bottom is fixed with joint (2), the main shaft middle part is equipped with garland axle sleeve (11), the garland axle sleeve is equipped with shading ring (12) outward, garland (13) is installed on the shading ring, the carbon brush (17) that is fixed on the carbon brush support (25) contacts with garland, be fixed with guide card (16) on the carbon brush, the prap (15) that is installed on the patchboard (14) of main shaft upper end links to each other with each garland by lead respectively, hole seat (6) on base and the base is gone up porose (5) and hole (7) respectively, on joint and the main shaft between also porose respectively (23), (19), guard shield (10) also is installed on the base.
2, logging winch collecting ring as claimed in claim 1 is characterized in that, gland (22) and gland (21) are arranged respectively on the main shaft (3) on described bearing (8) both sides, and sealing ring (4), sealing ring (20) are arranged respectively in the gland.
