Description

Technical Field

[0001] This utility model relates to the technical field of directional drilling equipment in coal mines, and in particular to a slip ring type cable conveyor. Background Technology

[0002] In directional drilling operations in coal mines, wired and wireless logging instruments are generally used. However, at certain depths, wired logging instruments outperform wireless instruments. In directional drilling, drilling mud is an essential requirement. Therefore, the water delivery device, with its unique single-action and sealing characteristics, ensures that the high-pressure hose connecting the mud pump truck does not become tangled or knotted during drill pipe rotation, while continuously delivering drilling fluid into the hole. This guarantees the power of the directional drilling tool and the mud flow required for slag and powder removal during drilling. However, if wired logging instruments are used, the water delivery device must be equipped with communication functionality. But if the cable-driven water delivery device is not properly designed, it may lead to signal instability and rapid seal failure during drill pipe rotation.

[0003] The existing solution is to use a self-compensating cable water supply device. This structure has certain defects due to the compensation of the inner core. During the rotation of the drill rod, the rotation of the inner core cannot be controlled, which leads to rapid wear of the probe. At the same time, the copper wire covered by the heat shrink tubing may become driven, causing the heat shrink tubing to fail quickly and resulting in a short circuit in the inner core, thus causing signal instability or even loss.

[0004] Therefore, it is necessary to provide a slip ring type cable-driven water supply device to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a slip ring type cable water delivery device, which solves the problem that the uncontrolled rotation of the inner core of the existing self-compensating cable water delivery device leads to rapid probe wear and heat shrink tubing failure causing short circuits in the inner core, resulting in unstable or even lost signals.

[0008] Preferably, a Gladwell ring is provided between the sealing ring and the mandrel, and a second O-ring is provided between the sealing ring and the water delivery device housing.

[0009] Preferably, a lip seal and a first O-ring are also provided between the mandrel and the water delivery device housing.

[0010] Preferably, a plurality of set screws are provided inside the other end of the outer side of the water dispenser housing.

During use, the mandrel, supported by both the deep groove ball bearing and the tapered roller bearing, remains relatively stationary as the water delivery device housing rotates with the drill rod.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] First Embodiment

[0018] Please refer to the following: Figure 1 , Figure 2 ,in, Figure 1A schematic diagram of the structure of a first embodiment of a slip ring type cable-connecting water supply device provided by this utility model; Figure 2 for Figure 1 The enlarged schematic diagram of part A is shown.

[0019] A slip ring type cable-connected water delivery device includes: a water delivery device housing 2; A support housing 4 is disposed at one end of the inner side of the water delivery device housing 2. A plastic male connector 3 is provided at one end of the support housing 4, and a plastic connector 1 is provided at one end of the plastic male connector 3. The conductor protection tube 9 has one end located inside the support housing 4. A mandrel 8 is provided on the outer side of the conductor protection tube 9. A sealing ring 5, a sealing pressure ring 6, a deep groove ball bearing 21, a bearing pressure ring 7, a self-made nut 20, and a tapered roller bearing 19 are provided on the outer side of the mandrel 8. A slip ring 13 is provided on the other end of the outer side of the conductor protection tube 9. An insulating locking nut 12 is provided on the other end of the conductor protection tube 9. Tailstock 10 is located at the other end of the outer side of the spindle 8, and a water tail bend 15 is provided at the bottom of the tailstock 10. The conductor 14 is disposed inside the conductor protection tube 9.

[0020] A third O-ring 25 is directly provided between the support housing 4 and the plastic male connector 3, a fourth O-ring 26 is provided between the plastic connector 1 and the plastic male connector 3, and an elastic retaining ring 24 is provided between the support housing 4 and the water delivery housing 2.

[0021] A Gladley ring 23 is provided between the sealing ring 5 and the mandrel 8, and a second O-ring 22 is provided between the sealing ring 5 and the water delivery housing 2.

[0022] A lip seal 16 and a first O-ring 18 are also provided between the mandrel 8 and the water delivery device housing 2.

[0023] Multiple set screws 17 are provided inside the other end of the outer side of the water delivery device housing 2.

[0024] The three main structures, namely the water delivery device housing 2, the wire conduit 9, and the slip ring 13, are integrated into a single kinematic pair, while the water delivery device spindle 8, the stator part of the slip ring 13, and the tailstock 10 are in a relatively stationary state.

[0025] The internal cable structure consists of a cable connector (taper), a wire 14, and an insulated locking nut 12. The wire 14 led out from the insulated locking nut 12 is connected to the external logging instrument receiver. The mandrel 8 and the water supply housing 2 are designed with tapered roller bearing 19, deep groove ball bearing 21, Glyd ring 23 and lip seal 16 in sequence to ensure good single-action and sealing performance between the mandrel 8 and the water supply housing 2.

[0026] The working principle of the slip ring type cable-connecting water supply device provided by this utility model is as follows: During directional drilling operations in coal mines, the plastic connector 1 is connected to the high-pressure hose of the mud pump truck, the water tail elbow 15 is connected to the drill pipe channel, the mud pump is started, and the mud passes through the plastic connector 1, the plastic male connector 3, the support shell 4, the water delivery device shell 2, and the tailstock 10 in sequence, and is finally transported to the drill pipe through the water tail elbow 15 to provide power for the directional drilling tool in the hole and to realize the functions of slag and powder removal. During this process, the drill pipe drives the water delivery device housing 2 to rotate synchronously, while the mandrel 8 remains relatively stationary (i.e., single-action) through the support of the tapered roller bearing 19 and the deep groove ball bearing 21, preventing the mandrel from rotating with the housing and causing the wire 14 to become entangled. The wire 14 is inserted into the wire protection tube 9, with one end connected to the external wired logging instrument through the slip ring 13, and the other end extending to the detection component inside the hole. The dynamic and static rings of the slip ring 13 cooperate to achieve stable signal transmission in the rotating state, replacing the traditional probe structure, avoiding wear and short circuit problems caused by uncontrolled rotation, and ensuring continuous and reliable communication signals. The third O-ring 25 between the support housing 4 and the plastic male connector 3, and the fourth O-ring 26 between the plastic connector 1 and the plastic male connector 3, prevent mud from leaking from the joint connection; the Gladley ring 23 between the sealing ring 5 and the spindle 8, the second O-ring 22 between the sealing ring 5 and the water delivery housing 2, and the lip seal 16 and the first O-ring 18 between the spindle 8 and the housing form a multi-layer sealing barrier to prevent mud from seeping into the area between the spindle 8 and the wire protection tube 9, protecting the internal cable structure; the elastic retaining ring 24 fixes the relative position of the support housing 4 and the water delivery housing 2.

[0027] Compared with related technologies, the slip ring type cable-connecting water supply device provided by this utility model has the following beneficial effects: The water delivery device housing 2, support housing 4, plastic male connector 3, plastic connector 1, wire protection tube 9, mandrel 8, sealing ring 5, sealing pressure ring 6, deep groove ball bearing 21, bearing pressure ring 7, tapered roller bearing 19, and slip ring 13 work together. During use, the mandrel 8, supported by the deep groove ball bearing 21 and tapered roller bearing 19, can remain relatively stationary when the water delivery device housing 2 rotates with the drill rod. This avoids the problem of uncontrolled rotation of the inner core in existing self-compensating cable water delivery devices and solves the problem of rapid wear of the probe caused by disordered rotation at the root. On the other hand, the wire 14 is run through the wire protection tube 9, and stable signal transmission in the rotating state is achieved through the slip ring 13. This replaces the traditional structure of heat shrink tubing covering copper wire and effectively prevents short circuits in the inner core caused by the failure of the heat shrink tubing, ensuring continuous and reliable communication signals.

[0028] Second Embodiment

[0029] Please refer to the following: Figure 3 and Figure 4 Based on the slip-ring type cable-through water supply device provided in the first embodiment of this application, the second embodiment of this application proposes another slip-ring type cable-through water supply device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0030] Specifically, the second embodiment of this application provides a slip ring type cable water supply device that differs in that it further includes a guide component 27, a plurality of locking screws 28, a plurality of mounting seats 29, and a plurality of balls 30. The guide component 27 is disposed on the outer side of the water supply device housing 2, the plurality of locking screws 28 are disposed on the outer side of the water supply device housing 2, the plurality of mounting seats 29 are disposed on the outer side of the guide component 27, and the plurality of balls 30 are evenly rolled inside the sides of the plurality of mounting seats 29.

[0031] The guide assembly 27 includes a first arc ring 271, a second arc ring 272, a snap-fit ​​groove 273, and a snap-fit ​​plate 274. The snap-fit ​​groove 273 is respectively opened at both ends of the first arc ring 271. The snap-fit ​​plate 274 is respectively fixedly installed at both ends of the second arc ring 272. The snap-fit ​​plate 274 is snapped into the inner side of the snap-fit ​​groove 273. A plurality of locking screws 28 are respectively disposed inside the first arc ring 271 and the second arc ring 272. One end of each of the plurality of locking screws 28 is threaded to the outer side of the water supply housing 2. A plurality of mounting seats 29 are respectively fixedly installed on the outer side of the first arc ring 271 and the second arc ring 272.

[0032] The snap-fit ​​plate 274 is snapped into the inner side of the snap-fit ​​groove 273. When in use, it can limit the movement between the first arc ring 271 and the second arc ring 272, and prevent displacement between the first arc ring 271 and the second arc ring 272. By using multiple ball bearings 30, the sliding connection can be converted into a rolling connection during use, reducing friction.

[0033] The working principle of the slip ring type cable-connecting water supply device provided by this utility model is as follows: When installing the guide assembly 27, the first arc ring 271 and the second arc ring 272 are attached to the outer side of the water supply housing 2, so that the snap plate 274 of the second arc ring is snapped into the snap groove 273 of the first arc ring to form a complete annular guide structure. Then, the locking screw 28 is screwed in to fix the guide assembly 27 on the water supply housing 2. During the process of the water feeder being lowered into the borehole along with the drill pipe, the ball bearings 30 inside the mounting base 29 contact the inner wall of the borehole, converting the sliding friction between the water feeder and the borehole wall into rolling friction, reducing the lowering resistance and preventing damage to the water feeder housing 2 due to friction; at the same time, the ball bearings 30 can radially limit the water feeder, preventing it from shifting or tilting in the borehole, ensuring that the mud delivery channel is aligned with the drill pipe, and avoiding mud delivery obstruction or joint leakage caused by shifting. If the guide assembly needs to be disassembled for maintenance, simply loosen the locking screw 28 and separate the first arc ring 271 and the second arc ring 272. The operation is convenient and does not affect the main structure of the water dispenser.

[0034] Compared with related technologies, the slip ring type cable-connecting water supply device provided by this utility model has the following beneficial effects: By cooperating with the guide assembly 27 and the ball bearing 30, the problem of high frictional resistance and easy deviation when the water feeder is lowered into the borehole is avoided during use, thereby reducing equipment wear and extending service life.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
