Description

Technical Field

[0001] This utility model relates to the field of rotary slip ring technology, specifically to a multi-channel pneumatic-electrohydraulic rotary slip ring. Background Technology

[0002] A rotary slip ring is a key electromechanical component used to transfer electrical energy, signals, or fluid media between rotating and stationary parts, enabling electrical or fluid connections during continuous rotational motion. Its core function is to solve problems such as wire entanglement, signal interruption, or fluid leakage during rotation.

[0003] Currently, multi-channel rotary slip rings, especially those for gas, electro-hydraulic applications, use seals to seal adjacent channels. Since rotary slip rings generally do not use transparent materials due to material properties and applications, after prolonged use, if the seals of adjacent channels fail, causing leakage between adjacent channels, such as gas to liquid leakage, it is impossible to directly observe and judge through the rotary slip ring. It can only be detected from the output end of the slip ring. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A multi-channel pneumatic-hydraulic rotary slip ring includes a sliding base and a sliding sleeve that are nested together. The sliding base and the sliding sleeve have three corresponding channels. Sealing components are installed on both sides of each channel in the sliding base and the sliding sleeve. Multiple microholes with equal spacing are opened on the sliding sleeve at the middle position corresponding to the sealing components.

[0006] Furthermore, the slide block is pre-set with a first channel one, a second channel one, and a third channel one, and the sliding sleeve is pre-set with a first channel two, a second channel two, and a third channel two corresponding to the first channel one, the second channel one, and the third channel one. The first, second, and third channels, a total of three channels, can be used as channels for gas, electro, and hydraulic systems. If needed, additional channels can be added to increase the number of any channel in the gas, electro, and hydraulic systems.

[0007] Furthermore, the outer side of the slide block is pre-set with three diameter reduction zones from left to right: a first diameter reduction zone, a second diameter reduction zone, and a third diameter reduction zone. The outer diameter of the slide block decreases sequentially at these three locations. A first channel is located between the upper left end of the slide block and the first diameter reduction zone; a second channel is located between the middle left end of the slide block and the third diameter reduction zone; and a third channel is located between the lower left end of the slide block and the second diameter reduction zone. The diameter reduction zones create a stepped surface structure on the slide block that decreases sequentially from left to right. Consequently, the interior of the sleeve connected to the slide block also has a stepped shape. This stepped structure extends the distance between adjacent channels, firstly reducing the risk of leakage by increasing the length, and secondly, the seal is located on the side of the diameter reduction zone. When the slide block and the sleeve are connected, the seal can be pressed against the seal to provide a better seal. Moreover, the side position of the seal facilitates installation.

[0008] Furthermore, an annular groove 1 is pre-set at the position corresponding to the first diameter reduction area, an annular groove 2 is pre-set at the position corresponding to the second diameter reduction area, and an annular groove 3 is pre-set at the position corresponding to the third diameter reduction area. The sides of the first, second, and third diameter reduction areas abut against the inner wall of the slide sleeve at their respective positions. The first channel 2, the second channel 2, and the third channel 2 are located on the slide sleeve at the positions corresponding to the annular grooves 1, 2, and 3. The annular grooves ensure that the three channels remain connected even when the slide sleeve rotates.

[0009] Furthermore, a sleeve is fixed at the middle position of the right end of the slide block. The slide sleeve and the slide block are rotatably supported by a support bearing. The support bearing includes a first bearing and a second bearing. The second bearing is installed between the outer side of the sleeve and the inner side of the corresponding slide sleeve. The first bearing is installed between the inner left end of the slide sleeve and the outer side of the corresponding slide block. An annular cover plate is installed between the slide block and the slide sleeve on the left side of the first bearing, and an annular cover plate is installed between the slide block and the slide sleeve on the right side of the second bearing. The support bearing ensures the stable rotation of the slide sleeve relative to the slide block, while providing a good and stable fixing environment for the seal.

[0010] Furthermore, a sealing assembly is provided between the slide block and the sliding sleeve. The sealing assembly includes seal one, seal two, seal three, and seal four. Seal one is installed on the slide block between the first channel one and the bearing one, and seal one abuts against the inner wall of the sliding sleeve at the corresponding position. Seal two is installed on the side of the reduced diameter area one of the first channel one on the slide block, and seal two abuts against the inner wall of the sliding sleeve at the corresponding position. Seal three is installed on the side of the reduced diameter area two of the third channel one on the slide block, and seal three abuts against the inner wall of the sliding sleeve at the corresponding position. Seal four is installed on the sleeve between the second channel one and the bearing two, and seal four abuts against the inner wall of the sliding sleeve at the corresponding position. The four seals seal both sides of the three channels and between adjacent channels. Different types of seals can be used for each position as needed.

[0011] Furthermore, on the left end of the slide block, corresponding to the positions of the first channel one, the second channel one, and the third channel one, a first channel connecting pipe one, a second channel connecting pipe one, and a third channel connecting pipe one are fixed respectively. On the sliding sleeve, corresponding to the positions of the first channel two, the second channel two, and the third channel two, a first channel connecting pipe two, a second channel connecting pipe two, and a third channel connecting pipe two are fixed respectively. Transparent cover rings are fixed to the outer side of the sliding sleeve at the micro-hole positions of sealing element one, sealing element two, sealing element three, and sealing element four. The connecting pipes ensure that the connected pipeline can be stably fixed to the slide block and the sliding sleeve. At the same time, the transparent cover rings are used to externally seal the micro-holes at the liquid channel positions, preventing excessive leakage to the sliding sleeve surface and causing large-area contamination in case of liquid leakage.

[0012] Furthermore, a carbon brush groove is formed in the sliding sleeve of the annular groove three, corresponding to the position of the second channel two. A brush assembly, including a carbon brush, is installed in the carbon brush groove and the position of the annular groove three. An insulating ring is installed in the annular groove three and is fixed to the corresponding sliding seat. The inner and outer sides of the insulating ring are grooved, and an outer copper ring and an inner copper ring are respectively installed in the inner and outer grooves. The outer and inner copper rings are fixedly connected by multiple copper pillars. The carbon brush abuts against the corresponding outer copper ring. An insulating coating is applied to the outer side of the carbon brush at a position offset from the outer copper ring. An insulating sleeve one passes through the second channel one of the sliding seat, and an insulating sleeve two passes through the second channel two of the sliding sleeve. The combination of the carbon brush and the copper ring maintains continuous circuit continuity, and the insulating sleeve combined with the insulating ring improves insulation performance.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides microholes at each sealing component location that connect to the outside of the sliding sleeve. When the sealing component fails and causes leakage, the leaking gas and liquid can simultaneously enter the microholes as they pass through the sealing component, allowing for effective observation from the outside of the sliding sleeve. This enables a quick and simple way to determine whether a leak has occurred.

[0015] 2. The trapezoidal fit between the slide block and the slide sleeve in this utility model increases the distance between adjacent channels. Combined with the sealing element, this improves the overall sealing performance. At the same time, the sealing element is located on the trapezoidal side, which facilitates the installation of the sealing element.

[0016] 3. In this utility model, a bearing is provided between the slide block and the slide sleeve to facilitate the rotation of the slide sleeve. At the same time, the annular cover plate can protect the bearing, reduce the entry of dust and other foreign objects, maintain the smooth rotation of the slide sleeve, and thus avoid leakage caused by excessive local wear of the sealant due to the eccentric rotation of the slide sleeve or slide block.

[0017] 4. The use of insulating sleeves and insulating rings in this invention to protect the circuit path can improve the insulation performance of the slip ring and reduce the risk of leakage. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] This application provides a multi-channel pneumatic-hydraulic rotary slip ring, mainly addressing the problem that current multi-channel rotary slip rings use seals between adjacent channels, but leakage in adjacent channels due to seal failure cannot be directly observed. The application provides the following technical solution, which will be discussed in conjunction with... Figures 1-7Please provide a detailed explanation:

[0028] A multi-channel pneumatic-hydraulic rotary slip ring includes a slide block 1 and a sliding sleeve 2. The outer side of the slide block 1 is provided with a first diameter reduction zone 14, a second diameter reduction zone 15, and a third diameter reduction zone 16 from left to right. The outer diameter of the slide block 1 at the positions of the first diameter reduction zone 14, the second diameter reduction zone 15, and the third diameter reduction zone 16 decreases sequentially. A first channel 11 is provided between the upper left end of the slide block 1 and the first diameter reduction zone 14. A second channel 12 is provided between the middle left end of the slide block 1 and the third diameter reduction zone 16. A third channel 13 is provided between the lower left end of the slide block 1 and the second diameter reduction zone 15.

[0029] An annular groove 24 is pre-set in the sliding sleeve 2 at the position corresponding to the first diameter reduction area 14, an annular groove 25 is pre-set in the sliding sleeve 2 at the position corresponding to the second diameter reduction area 15, and an annular groove 26 is pre-set in the sliding sleeve 2 at the position corresponding to the third diameter reduction area 16. The sliding seat 1 and the sliding sleeve 2 are sleeved together. The sides of the first diameter reduction area 14, the second diameter reduction area 15, and the third diameter reduction area 16 abut against the inner wall of the sliding sleeve 2 at the corresponding positions. The sliding sleeve 2 is provided with a first channel 21, a second channel 22, and a third channel 23 at the positions corresponding to the first annular groove 24, the second annular groove 25, and the third annular groove 26, respectively. The first channel 11 and the first channel 21, the second channel 12 and the second channel 22, and the third channel 13 and the third channel 23 are connected by the annular groove 24, the annular groove 25, and the annular groove 26, respectively.

[0030] A sleeve 213 is fixed at the middle position of the right end of the slide block 1. The slide block 2 and the slide block 1 are rotatably supported by a support bearing 4. The support bearing 4 includes a first bearing 41 and a second bearing 42. The second bearing 42 is installed between the outer side of the sleeve 213 and the inner side of the corresponding slide block 2. The first bearing 41 is installed between the inner left end of the slide block 2 and the outer side of the corresponding slide block 1. An annular cover plate 43 is installed between the slide block 1 and the slide block 2 on the left side of the first bearing 41. An annular cover plate 44 is installed between the slide block 1 and the slide block 2 on the right side of the second bearing 42.

[0031] A sealing assembly 3 is provided between the slide block 1 and the slide sleeve 2. The sealing assembly 3 includes a first seal 31, a second seal 32, a third seal 33, and a fourth seal 34. The first seal 31 is installed on the slide block 1 between the first channel 11 and the bearing 41, and the first seal 31 abuts against the inner wall of the slide sleeve 2 at the corresponding position. The second seal 32 is installed on the side of the reduced diameter area 14 of the first channel 11 on the slide block 1, and the second seal 32 abuts against the inner wall of the slide sleeve 2 at the corresponding position. The third seal 33 is installed on the side of the reduced diameter area 15 of the third channel 13 on the slide block 1, and the third seal 33 abuts against the inner wall of the slide sleeve 2 at the corresponding position. The fourth seal 34 is installed on the sleeve 213 between the second channel 12 and the bearing 42, and the fourth seal 34 abuts against the inner wall of the slide sleeve 2 at the corresponding position.

[0032] Multiple microholes 210 with equal spacing are provided on the sliding sleeve 2 at the middle positions corresponding to the first seal 31, the second seal 32, the third seal 33 and the fourth seal 34.

[0033] The first channel 11 and the first channel 2 12 work together, the second channel 12 and the second channel 2 22 work together, and the third channel 1 13 and the third channel 2 23 work together to form three passages, which can be supplied with gas, electricity and hydraulic connections respectively. Each passage is separated and sealed on both sides by a seal. When the seal at a certain position fails and a leak occurs, the leaking gas or liquid will enter the micropore 210 simultaneously when passing through the seal at that position. The liquid can flow to the outer surface of the sliding sleeve 2 through the micropore 210, so the liquid leak can be directly observed with the naked eye. When the gas is discharged through the micropore 210, it can produce the sound of gas being released. It can also be probed by approaching the micropore 210, and the gas leak can also be observed. This allows workers to directly observe whether the internal seal has failed and caused a leak from the slip ring position.

[0034] In some embodiments, the left end of the slide block 1 is fixed with a first channel connecting pipe 17, a second channel connecting pipe 18, and a third channel connecting pipe 19 corresponding to the positions of the first channel 11, the second channel 12, and the third channel 13, respectively. The slide sleeve 2 is fixed with a first channel connecting pipe 27, a second channel connecting pipe 28, and a third channel connecting pipe 29 corresponding to the positions of the first channel 21, the second channel 22, and the third channel 23, respectively. The outside of the slide sleeve 2 is fixed with a transparent cover ring 211 corresponding to the positions of the micropores 210 of the seal 31, the seal 32, the seal 33, and the seal 4 34.

[0035] The connecting pipes of each channel are designed to facilitate connection with the slide block 1 and the slide sleeve 2, thereby forming a convenient gas-liquid-electric transport. The three channels can decide which channel is used to transport gas, liquid or other substances as needed. At the same time, the transparent cover ring 211 can prevent the leaked liquid from continuing to flow out, keeping it at a level that can be observed by the naked eye of the worker, avoiding significant soiling of the surface of the slide sleeve 2. Meanwhile, to ensure the visibility of the gas passage, the transparent cover ring 211 is not provided at the position of the micro-hole 210 of the gas passage.

[0036] In some embodiments, a carbon brush groove 212 is provided in the sliding sleeve 2 of the annular groove 26 corresponding to the position of the second channel 22. A brush assembly 5 is installed in the carbon brush groove 212 and the position of the annular groove 26. The brush assembly 5 includes a carbon brush 51, which is installed in the carbon brush groove 212. An insulating ring 52 is installed in the annular groove 26 and is fixedly fitted onto the sliding seat 1 at the corresponding position. The inner and outer sides of the insulating ring 52 are grooved. An outer copper ring 53 and an inner copper ring 54 are respectively installed in the inner and outer grooves. The outer copper ring 53 and the inner copper ring 54 are fixedly connected by multiple copper pillars 55. The carbon brush 51 abuts against the outer copper ring 53 at the corresponding position. An insulating coating is provided on the outer side of the carbon brush 51 that is offset from the outer copper ring 53. An insulating sleeve 56 passes through the second channel 12 of the sliding seat 1, and an insulating sleeve 57 passes through the second channel 22 of the sliding sleeve 2.

[0037] When the circuit is running, the two wires are passed through insulating sleeve 1 56 and insulating sleeve 2 57 respectively and fixed to the inner copper ring 54 and carbon brush 51 to form an electric slip ring structure, which can ensure circuit continuity. Insulating sleeve 1 56, insulating sleeve 2 57 and insulating ring 52 can insulate and isolate the wires and copper rings to prevent leakage.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
