Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of channel docking, in particular to a channel joint. BACKGROUND

[0002] During channel transportation, it is often necessary to disassemble or replace the channel, especially when the length of the channel needs to be adjusted or repaired. Traditional channel connection methods mostly use flange connection or threaded connection, which has the problem of low disassembly and assembly efficiency in actual application.

[0003] At present, most quick connectors use a male connector and a female connector nested structure. The male connector has a convex top clamping block on the outer wall, and the female connector has a ring-shaped groove on the inner wall. The male and female connectors are axially locked by mechanical rotation interlocking of the clamping block and the groove. However, the nested structure of the male and female connectors is suitable for channels with small shaft diameters. For channels or pipelines with large shaft diameters, large rotating devices need to be used, which increases the cost and reduces the efficiency of docking. Therefore, how to facilitate channel docking and improve the efficiency of channel docking is a technical problem that needs to be solved by those skilled in the art. SUMMARY

[0004] The problem solved by the present application is how to facilitate channel docking and improve the efficiency of channel docking.

[0005] To solve the above problems, the present application provides a channel joint, comprising: a meshing worm gear and a worm; a lead screw sleeve arranged in the inner hole of the worm gear, the outer side wall of the lead screw sleeve being threadedly connected with the inner side wall of the worm gear, so that the lead screw sleeve can move along the axial direction of the worm gear; a first sleeve arranged at the first end of the lead screw sleeve, the first sleeve being in communication with the lead screw sleeve, and the first sleeve being used for sealingly communicating with a first channel; a first housing surrounding at least the second end of the lead screw sleeve, and being used for sealingly communicating with a second channel.

[0006] Optionally, a plurality of guide blocks are arranged on the outer side wall of the second end of the lead screw sleeve, and the guide blocks are arranged along the circumferential direction of the lead screw sleeve. The inner side wall of the first housing is provided with a plurality of guide grooves corresponding to the guide blocks, and the guide grooves extend along the axial direction of the first housing. The guide blocks are arranged in the corresponding guide grooves.

[0007] Optionally, the channel joint further comprises a second housing surrounding at least the first end of the lead screw sleeve, the worm gear and the worm. The second housing is provided with a first through hole, the extension direction of the first through hole being perpendicular to the axial direction of the worm gear, and the worm being arranged in the first through hole.

[0008] Optionally, the channel connector further includes a bearing disposed between the second housing and the worm gear, so that the worm gear can rotate relative to the second housing.

[0009] Optionally, the outer surface of the second housing includes a first plane corresponding to the first through hole.

[0010] Optionally, the second housing further surrounds the end of the first sleeve near the lead screw sleeve; wherein the orthographic projection of the end of the first sleeve away from the lead screw sleeve along the axial direction of the second housing overlaps with the end face of the second housing away from the first housing.

[0011] Optionally, a sealing ring is provided on the end face of the first sleeve away from the lead screw sleeve.

[0012] Optionally, a first groove is provided on the end face of the first sleeve away from the lead screw sleeve, and the sealing ring is disposed in the first groove; wherein, in the uncompressed state of the sealing ring, the thickness of the sealing ring along the axial direction of the first sleeve is greater than the depth of the first groove.

[0013] Optionally, the first sleeve has an annular protrusion on the end face away from the lead screw sleeve, and the annular protrusion is located on the side of the sealing ring away from the center of the first sleeve.

[0014] Optionally, a displacement sensor is provided on the outer wall of the first sleeve, the displacement sensor being used to correspond to the end face of the first channel near the first sleeve.

[0015] The beneficial effects of this invention are as follows: The channel connector includes a meshing worm gear and worm, a lead screw sleeve, a first sleeve, and a first housing. The outer wall of the lead screw sleeve is threadedly engaged with the inner wall of the worm gear, allowing the lead screw sleeve to move axially along the worm gear. The first sleeve is located at the first end of the lead screw sleeve and is used to abut against and seal with the first channel. The first housing at least surrounds the second end of the lead screw sleeve and is used to seal with the second channel. The two ends of the channel connector connect the first channel and the second channel. Before docking, the gate valves on the first channel and / or the second channel are closed to ensure that the internal environment of the channel is isolated from the external environment. The second channel directly connects to the first channel. A housing is connected, and the relative position of the first channel and the first housing is adjusted to keep the first channel and the second channel coaxially aligned. Then, by rotating the worm gear, the worm wheel rotates circumferentially, which drives the lead screw sleeve to move axially along the worm wheel, thereby driving the first sleeve to move axially along the worm wheel. The first sleeve moves away from the worm wheel to abut and seal with the first channel, realizing the connection between the first channel and the second channel. After the connection is completed, the gate valve on the first channel and / or the second channel is opened, which realizes the connection between the first channel and the second channel, which facilitates the connection of the channels and improves the connection efficiency of the channels.

[0021] It should be noted that the terms "a" and "a plurality of" used in this invention are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0022] During channel transportation, channels often need to be disassembled or replaced, especially when adjusting channel length or performing maintenance. Traditional channel connection methods mostly use flange or threaded connections, which suffer from low disassembly and assembly efficiency in practical applications. Currently, most quick-connect fittings adopt a nested male and female connector structure. The male connector has a raised locking block on its outer wall, and the female connector has an annular groove on its inner wall. Axial locking is achieved through mechanical rotational interlocking of the locking block and the groove. However, the nested male and female connector structure is suitable for channels with small shaft diameters. For channels or pipelines with larger shaft diameters, this structure requires large rotating devices, resulting in higher docking costs and lower docking efficiency. Therefore, how to facilitate channel docking and improve channel docking efficiency is a technical problem that urgently needs to be solved by those skilled in the art.

[0023] To address the problems existing in the aforementioned related technologies, the present invention provides a channel connector 10, combined with... Figures 1 to 5 As shown, a channel connector 10 includes a meshing worm gear 21 and worm 22, a lead screw sleeve 30, a first sleeve 40, and a first housing 50. The lead screw sleeve 30 passes through the inner hole of the worm gear 21, and the outer side wall of the lead screw sleeve 30 is threadedly engaged with the inner side wall of the worm gear 21, so that the lead screw sleeve 30 can move axially along the worm gear 21. The first sleeve 40 is disposed at the first end D1 of the lead screw sleeve 30, and the first sleeve 40 is connected to the lead screw sleeve 30. The first sleeve 40 is used to abut against and seal with the first channel 11. The first housing 50 at least surrounds the second end D2 of the lead screw sleeve 30 and is used to seal with the second channel 12.

[0024] Please refer to the details. Figure 1 , Figure 3 , Figure 4The channel connector 10 connects the first channel 11 and the second channel 12 at both ends. Before docking, the gate valve 13 on the first channel 11 and / or the second channel 12 is closed to ensure that the internal environment of the channel is isolated from the external environment. The second channel 12 is directly connected to the first housing 50. The relative position of the first channel 11 and the first housing 50 is adjusted so that the first channel 11 and the second channel 12 are coaxially aligned. Then, by rotating the worm gear 22, the worm wheel 21 is rotated circumferentially, which drives the screw sleeve 30 to move axially along the worm wheel 21, thereby driving the first sleeve 40 to move axially along the worm wheel 21. The first sleeve 40 moves towards the side away from the worm wheel 21 to abut against the first channel 11 and seal the connection, thus realizing the connection between the first channel 11 and the second channel 12. After docking, the gate valve 13 on the first channel 11 and / or the second channel 12 is opened, which realizes the connection between the first channel 11 and the second channel 12, which facilitates the docking connection of the channels and improves the docking efficiency of the channels.

[0025] Meanwhile, the transmission engagement between the worm gear 21 and the worm 22 has a self-locking characteristic, which can maintain the current position stability without external force. The worm will not drive the worm 22 to rotate, and the sealing between the channels can be guaranteed even when the motor is powered off, preventing leakage accidents and thus ensuring the reliability of the connection.

[0026] Understandably, please refer to the details. Figure 1 , Figure 3 , Figure 4 The lead screw sleeve 30 and the first sleeve 40 are hollow along their axial direction to facilitate the smooth passage of the medium. The medium can be a substance in different forms, such as gas, liquid, or powder, and is not specifically limited here. During the docking process, the relative position of the first channel 11 and the first outer shell 50 is adjusted so that the first channel 11 and the second channel 12 are coaxially aligned. Then, the worm gear 22 can be rotated in the forward direction to drive the worm wheel 21 to rotate, thereby causing the lead screw sleeve 30 to move away from the worm wheel 21 along its axial direction. This, in turn, drives the first sleeve 40 to move synchronously until the first sleeve 40 is tightly fitted with the end face of the first channel 11. Rotation of the worm gear 22 is then stopped, at which point a sealed connection is formed between the first sleeve 40 and the first channel 11, ensuring that no leakage occurs during the transmission of the medium. After the sealed connection is completed, the worm gear 22 can be rotated in the reverse direction to partially retract the lead screw sleeve 30 and the first sleeve 40 for disassembly and reconnection. Here, forward rotation and reverse rotation refer to the rotation of the worm gear 22 in different directions. The specific direction can be set according to the actual assembly requirements. For example, clockwise rotation is forward and counterclockwise rotation is reverse. No specific limitation is made here.

[0027] In some embodiments, please refer to the following for details. Figure 2The second end D2 of the lead screw sleeve 30 has a plurality of guide blocks 31 on its outer side wall, and the plurality of guide blocks 31 are arranged circumferentially along the lead screw sleeve 30. The inner side wall of the first housing 50 has a plurality of guide grooves 51 corresponding to the plurality of guide blocks 31, and the guide grooves 51 extend axially along the first housing 50. The guide blocks 31 are disposed in the corresponding guide grooves 51. The guide blocks 31 are disposed in the guide grooves 51 and the guide grooves 51 extend axially along the first housing 50, which can restrict the circumferential rotational freedom of the lead screw sleeve 30, ensuring that the lead screw sleeve 30 can only move axially with the rotation of the worm gear 21, avoiding deflection or rotation of the lead screw sleeve 30 during axial movement, ensuring the coaxiality of the first sleeve 40 and the first channel 11 when they are docked, preventing docking misalignment caused by the rotation of the lead screw sleeve 30, and improving docking accuracy and connection stability. Multiple guide blocks 31 are evenly distributed around the lead screw sleeve 30, and cooperate with multiple corresponding guide grooves 51 to make the lead screw sleeve 30 more evenly stressed during axial movement, avoid jamming or tilting caused by unilateral stress, ensure smooth movement, and further improve the stability and efficiency of the docking process.

[0028] In some embodiments, please refer to the following for details. Figure 1 , Figure 3 , Figure 4 The channel connector 10 further includes a second housing 60, which at least surrounds the first end D1 of the lead screw sleeve 30, the worm gear 21, and the worm 22; wherein the second housing 60 is provided with a first through hole 61, the extension direction of the first through hole 61 is perpendicular to the axial direction of the worm gear 21, and the worm 22 passes through the first through hole 61. The second outer shell 60 encloses the first end D1 of the lead screw sleeve 30, the worm gear 21, and the worm 22, forming a closed protective space. This effectively prevents external dust, impurities, and liquids from entering the transmission area, avoiding impurities from affecting the meshing accuracy of the worm gear 21 and worm 22 or the smoothness of the lead screw sleeve 30's movement, thus extending the device's maintenance cycle and service life. The first through hole 61 is set in a direction perpendicular to the axial direction of the worm gear 21 and allows the worm 22 to pass through, ensuring a suitable and correct meshing angle between the worm 22 and the worm gear 21, guaranteeing transmission efficiency. The first through hole 61 provides a stable installation position for the worm 22, preventing axial or radial displacement of the worm 22 during transmission, ensuring the stability and accuracy of the transmission.

[0029] For details, please refer to [link / reference]. Figure 3 The second outer casing 60 is connected to the end of the first outer casing 50.

[0030] In some embodiments, please refer to the following for details. Figure 4The channel connector 10 also includes a bearing 71 disposed between the second housing 60 and the worm gear 21, allowing the worm gear 21 to rotate relative to the second housing 60. The bearing 71, positioned between the second housing 60 and the worm gear 21, converts the sliding friction between the worm gear 21 and the second housing 60 into rolling friction, significantly reducing the frictional force during the rotation of the worm gear 21. This makes it easier and less strenuous for the worm 22 to drive the worm gear 21, further reducing the driving force required for docking. The bearing 71 provides precise radial and axial positioning for the rotation of the worm gear 21, reducing radial runout or axial movement during rotation, ensuring the thread fit accuracy between the worm gear 21 and the lead screw sleeve 30, ensuring the smoothness and accuracy of the axial movement of the lead screw sleeve 30, and improving docking accuracy.

[0031] For details, please refer to [link / reference]. Figure 4 The channel connector 10 also includes a bearing sleeve 72 for fixing the bearing 71. The bearing sleeve 72 is fixed on the second housing 60 to press and position the outer ring of the bearing 71, ensuring that the bearing 71 will not move axially or radially during operation, thereby further improving the stability and accuracy of the worm gear 21 rotation.

[0032] In some embodiments, please refer to the following for details. Figure 3 The outer surface of the second housing 60 includes a first plane 62 corresponding to the first through hole 61. The first plane 62, corresponding to the first through hole 61, provides a flat mounting reference surface for the drive assembly of the worm gear 22, such as a motor. The drive assembly can be directly fixed to the first plane 62 by bolts or other connecting parts, ensuring that the output shaft of the drive device is coaxial with the worm gear 22, avoiding transmission eccentricity caused by the tilt of the mounting surface, improving transmission efficiency, and reducing additional stress and component wear.

[0033] Specifically, the channel connector 10 further includes a drive assembly, which includes a drive member and a connector. The drive member is fixedly connected to one end of the worm gear 22 via the connector to provide a stable and reliable driving force input. The drive assembly is disposed at the first plane 62 of the second housing 60, and the output shaft of the drive member is coaxial with the worm gear 22 to ensure the accuracy and stability of the transmission.

[0034] In some embodiments, please refer to the following for details. Figure 1 , Figure 3 , Figure 4The second outer shell 60 also surrounds the end of the first sleeve 40 near the lead screw sleeve 30; wherein, the orthographic projection of the end of the first sleeve 40 away from the lead screw sleeve 30 along the axial direction of the second outer shell 60 overlaps with the end face of the second outer shell 60 away from the first outer shell 50. The second outer shell 60 surrounds the end of the first sleeve 40, forming a protective barrier for the connection between the first sleeve 40 and the lead screw sleeve 30, preventing structural damage caused by external objects colliding with the connection during the docking process; the orthographic projection of the end of the first sleeve 40 away from the lead screw sleeve 30 along the axial direction overlaps with the end face of the second outer shell 60, meaning that throughout the entire process of the first sleeve 40 moving towards the first channel 11, the portion of the first sleeve 40 near the lead screw sleeve 30 is always surrounded by the second outer shell 60, while the portion away extends outward to increase the contact area between the first sleeve 40 and the first channel 11, thereby improving the sealing performance between the first sleeve 40 and the first channel 11, ensuring a good sealing effect under high pressure or high vibration environments, and preventing media leakage.

[0035] In some embodiments, please refer to the following for details. Figure 4 A sealing ring 80 is provided on the end face of the first sleeve 40 away from the lead screw sleeve 30. The sealing ring 80 can be an elastic component, such as rubber or silicone. When the first sleeve 40 abuts against the first channel 11, the sealing ring 80 is compressed and fills the tiny gap between the end faces, achieving a reliable seal between the first sleeve 40 and the first channel 11. This prevents leakage of the medium in the channel or the entry of external impurities into the channel, ensuring the cleanliness and pressure stability of the environment inside the channel. It is particularly suitable for working conditions requiring strict sealing, such as high pressure or corrosive environments. The sealing ring 80 on the end face is easy to replace, requiring only the removal of the sealing ring 80 to replace the sealing component. For certain specific situations, especially in high-radiation media environments, the sealing ring 80 can be quickly replaced, reducing the risk of maintenance personnel coming into contact with harmful media.

[0036] In some embodiments, please refer to the following for details. Figure 4The first sleeve 40 has a first groove 41 on its end face away from the lead screw sleeve 30, and the sealing ring 80 is disposed in the first groove 41. When the sealing ring 80 is not compressed, its thickness along the axial direction of the first sleeve 40 is greater than the depth of the first groove 41. The first groove 41 provides a fixed installation position for the sealing ring 80, preventing it from shifting or falling off during the mating process due to compression or friction, ensuring that the sealing ring 80 is always in the correct sealing position and guaranteeing the stability of the sealing effect. When the sealing ring 80 is not compressed, its thickness is greater than the depth of the first groove 41. During mating, the sealing ring 80 is fully compressed, and the portion protruding from the first groove 41 is deformed by compression, which enhances the tightness of the fit between the sealing ring 80 and the end face of the first channel 11, improving the sealing performance. Simultaneously, it can compensate for processing errors or minor deformations of the two mating surfaces, ensuring reliable sealing even with slight dimensional deviations.

[0037] It is understood that the first groove 41 is an annular groove.

[0038] In some embodiments, please refer to the following for details. Figure 4 The first sleeve 40 has an annular protrusion 42 on its end face away from the lead screw sleeve 30. The annular protrusion 42 is located on the side of the sealing ring 80 away from the center of the first sleeve 40. The annular protrusion 42 surrounds the outer side of the sealing ring 80. During the docking process between the first sleeve 40 and the first channel 11, the annular protrusion 42 can first contact the end face of the first channel 11, playing a pre-positioning role. This ensures that the sealing ring 80 can be accurately aligned with the sealing area of ​​the first channel 11, avoiding misalignment of the sealing ring 80 due to docking misalignment and guaranteeing the sealing effect. The annular protrusion 42 is higher than the end face of the first sleeve 40, which can prevent external dust, liquid, and other impurities from entering the area where the sealing ring 80 is located, protecting the sealing ring 80 from contamination or damage and extending its service life.

[0039] For details, please refer to [link / reference]. Figure 4 The end face of the first sleeve 40 away from the lead screw sleeve 30 has an annular mounting plane 43, which is parallel to the end face of the first channel 11. The mounting plane 43 is located on the side of the first groove 41 away from the annular protrusion 42, so as to mate with the sealing structure 14 on the end face of the first channel 11. The mounting plane 43 fits tightly with the sealing structure 14 on the end face of the first channel 11, ensuring that the sealing ring 80 is uniformly stressed under compression, further improving the sealing reliability.

[0040] In some embodiments, please refer to the following for details. Figure 4A displacement sensor 90 is provided on the outer wall of the first sleeve 40. The displacement sensor 90 corresponds to the end face of the first channel 11 near the first sleeve 40. The displacement sensor 90 can detect the distance between the end face of the first sleeve 40 and the end face of the first channel 11 in real time. When the first sleeve 40 moves towards the first channel 11, the sensor feeds back the position signal to the control system, realizing precise monitoring of the docking process and avoiding component damage caused by excessive movement, such as the sealing ring 80 being over-compressed and failing, or poor sealing caused by insufficient movement.

[0041] Specifically, the displacement sensor 90 can be a laser displacement sensor 90 or a trigger-type displacement sensor 90. Different types of sensors are selected according to actual needs to adapt to the working environment. The laser displacement sensor 90 has the advantage of non-contact measurement and is suitable for high-precision docking scenarios, and can monitor micron-level displacement changes in real time. The trigger-type displacement sensor 90, on the other hand, triggers a signal through physical contact. When the first sleeve 40 contacts the end face of the first channel 11 or reaches a predetermined compression amount, it outputs a signal. Through the feedback control of the displacement sensor 90, automated docking operations can be realized, improving assembly efficiency and reliability.

[0042] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
