A transport device and method for using cylindrical parts

Abstract

A conveying device and method for cylindrical parts are disclosed, comprising an inlet section, a receiving section, and a take-out section connected in sequence, each cylindrical in shape. The take-out section is connected to a cover plate. In application, the high-speed moving cylindrical part first enters the inlet section, creating an annular slit flow phenomenon, i.e., a pressure difference exists between the two ends of the cylindrical part, which brakes the part. If the cylindrical part brakes in the inlet or receiving section, high-pressure liquid is discharged from the end of the receiving section closest to the take-out section. This high-pressure liquid then carries the cylindrical part into the take-out section, where the cover plate is opened to remove it. The conveying process requires no other parts to reverse, resulting in high conveying efficiency. The braking position of the cylindrical part can be adjusted by discharging liquid, ensuring the part ultimately reaches the take-out cavity, thus improving the conveying effect. Therefore, this design offers high conveying efficiency and is effective for conveying cylindrical parts.

[0001] This invention relates to a transportation device, belonging to the field of underwater transportation parts, and particularly to a transportation device and method for using cylindrical parts. Background Technology

[0002] There is often a need to transport goods underwater. To ensure the effectiveness of the transport, various devices are used to transport goods.

[0003] Chinese patent application number 202311342230.1, filed on October 17, 2023, discloses a pipeline and transportation method for transporting marine minerals. The pipeline includes a fixed box connected to a conveying pipe and an inlet pipe. A conveying mechanism is installed inside the conveying pipe, comprising conveying grooves evenly distributed on the inner wall of the pipe. This conveying mechanism enables the transport of minerals and allows movement within the pipeline, including climbing and descending, thus facilitating reciprocating transport. A pushing mechanism is also included to push a conveying tray and a conveying cylinder into the pipeline for easy transport. The conveying tray and cylinder can be cyclically supplied, positioning them at appropriate locations to facilitate the addition of minerals. While this design achieves the effect of transporting goods via a pipeline, it still has the following drawbacks:

[0004] In this design, the conveying mechanism needs to climb and descend back and forth in the conveying pipeline to carry out transportation, that is, the conveying mechanism needs to perform a back-and-forth motion, so it takes a long time and the conveying efficiency is low.

[0005] The information disclosed in this background section is intended only to enhance understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to overcome the defects and problems of low conveying efficiency in the prior art, and to provide a conveying device and method for cylindrical parts with high conveying efficiency.

[0007] To achieve the above objectives, the technical solution of the present invention is:

[0008] A transport device suitable for cylindrical parts, the device comprising an entry section, a receiving section and an extraction section;

[0009] The middle part of the receiving section is a receiving cavity, which is cylindrical. One end of the receiving cavity is connected to one end of the entering cavity of the entering section, which is also cylindrical. The end of the receiving section away from the entering cavity is connected to one end of the taking-out cavity of the taking-out section, which is cylindrical. The other end of the taking-out section is detachably connected to the cover plate.

[0010] A drain valve is provided at the end of the receiving section away from the inlet cavity. The drain valve includes a drain valve core, and the movement stroke of the drain valve core is to rotate within the drain valve.

[0011] The top of the drain valve core is connected to one end of the drain valve stem, and the other end of the drain valve stem extends out of the drain valve and is connected to one end of the drain handle.

[0012] An inlet ball valve is provided at one end of the inlet section, and the middle part of the inlet ball valve includes an inlet valve core. The movement stroke of the inlet valve core is to rotate within the inlet ball valve.

[0013] The top of the inlet valve core is connected to one end of the inlet valve stem, and the other end of the inlet valve stem extends out from the top of the inlet ball valve and is connected to one end of the inlet handle.

[0014] An entry switch is provided at the end of the receiving section near the entry section, and an exit switch is provided at the end of the receiving section near the exit section.

[0015] The entry switch is a metal sensor, and the exit switch is a metal sensor.

[0016] The entry switch is a Hall sensor or a capacitive sensor, and the exit switch is a Hall sensor or a capacitive sensor.

[0017] The receiving section includes multiple pipes connected in sequence, with flanges of two adjacent pipes facing each other and the flanges connected by fixing screws. A sealing ring is sandwiched between the flanges of two adjacent pipes.

[0018] The receiving section is connected to a vertically upward exhaust pipe at one end near the taking section. One end of the exhaust pipe is connected to one end of the receiving cavity, and an exhaust valve is provided on the exhaust pipe.

[0019] The exhaust valve includes an exhaust port with the opening facing upwards, and the exhaust port is detachably connected to an exhaust cover.

[0020] A method of using a transport device suitable for cylindrical parts, the method comprising the following steps:

[0021] Step 1: First connect the cover plate to the extraction section, then introduce liquid into the inlet chamber, receiving chamber, and extraction chamber to ensure that the inlet chamber, receiving chamber, and extraction chamber are all filled with the specified hydraulic pressure;

[0022] Step 2: The cylindrical part moving at a certain speed first enters the inlet cavity. At this time, the outer surface of the cylindrical part and the inner surface of the inlet cavity form an annular gap. Therefore, the liquid will form an annular gap flow phenomenon. The liquid at the front end of the cylindrical part will generate greater pressure, while the liquid at the rear end of the cylindrical part will have less pressure. This pressure difference causes the cylindrical part to gradually stop moving, thereby achieving the braking effect on the cylindrical part.

[0023] Step 3: Includes any one or a combination of the following:

[0024] If the cylindrical part is located in the inlet or receiving cavity when it is braked: the liquid is discharged from the end of the receiving section that is close to the take-out section. At this time, the high-pressure liquid moves towards the take-out section, and the cylindrical part moves towards the take-out section under the drive of the high-pressure liquid. After the high-pressure liquid is discharged, the cylindrical part is braked in the take-out cavity.

[0025] If the cylindrical part is located in the extraction cavity when braked: remove the cover plate and then remove the cylindrical part from the extraction cavity.

[0026] Step 4: Repeat steps 2 and 3 in sequence until all cylindrical parts have been transported.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. In this invention, a transport device and method for cylindrical parts are disclosed. The device includes an entry section, a receiving section, and a take-out section. The middle part of the receiving section is a receiving cavity. One end of the receiving cavity is connected to the entry cavity of the entry section, and the other end of the receiving section is connected to the take-out cavity of the take-out section. A drain valve is provided on the receiving end. A cover plate is detachably connected to the other end of the take-out section. In application, the entry cavity, receiving cavity, and take-out cavity are first filled with liquid at a specified pressure. Then, the cylindrical part is moved into the entry cavity at a certain speed, i.e., there is relative motion between the cylindrical part and the entry cavity. Furthermore, an annular gap is formed between the outer surface of the cylindrical part and the inner surface of the inlet cavity, resulting in an annular gap flow phenomenon. This phenomenon causes higher pressure at the front end of the cylindrical part and lower pressure at the rear end, causing the cylindrical part to gradually stop moving. If the cylindrical part is braked in the inlet or receiving cavity, and then the drain valve discharges liquid, the high-pressure liquid will drive the cylindrical part towards the drain valve, thus eventually braking in the removal cavity. If the cylindrical part brakes in the removal cavity, the cover plate can be removed, allowing the cylindrical part to be removed from the removal cavity. The advantages of this invention also include:

[0029] Firstly, the high-speed cylindrical parts can be transported within the inlet, receiving, and retrieval cavities without requiring the parts to turn back, thus resulting in higher transport efficiency compared to existing technologies. Furthermore, once the inlet, receiving, and retrieval sections are manufactured, they can be used for a long period of time, enabling the long-term transport of cylindrical parts.

[0030] Secondly: The cylindrical part is braked by the annular gap flow phenomenon. Then, the braking position of the cylindrical part is observed. If the cylindrical part is braked in the inlet or receiving cavity, the high-pressure liquid is discharged through the drain valve. Therefore, the high-pressure liquid moves the cylindrical part towards the receiving cavity, and then the cylindrical part is braked in the receiving cavity. If the cylindrical part is braked in the receiving cavity, the cover plate can be opened and the cylindrical part can be directly removed. The cylindrical part is braked by the pressure difference generated by the annular gap flow phenomenon. Therefore, the braking process does not depend on other parts, which makes the size of the device smaller.

[0031] Thirdly: The final braking position of the cylindrical part can be adjusted by the drain valve, so that the cylindrical part finally reaches the extraction cavity, thus ensuring the transportation effect of the cylindrical part.

[0032] Therefore, the present invention has high conveying efficiency and good conveying effect for cylindrical parts.

[0033] 2. In the present invention, a transport device and method for cylindrical parts, an entry ball valve is provided at one end of the entry section, and an entry valve core is provided inside the entry ball valve. The top of the entry valve core is connected in sequence to the entry valve stem and the entry handle. In application, the entry handle is rotated first, and then the entry handle drives the entry valve stem and the entry valve core to rotate in sequence. The entry valve core can be rotated to communicate with or not communicate with the entry cavity, thus achieving the effect of opening and closing the entry cavity. The entry cavity can be opened and closed by rotating the entry handle, so it is easy to operate. Moreover, compared with other opening and closing components, the entry ball valve is smaller in size, so it can make efficient use of space. Therefore, the present invention is easy to operate.

[0034] 3. In the present invention, a transport device and method for cylindrical parts, an entry switch is provided at the end of the receiving section near the entry section, and an exit switch is provided at the end of the receiving section near the exit section. During application, if both the entry and exit switches detect the cylindrical part, it indicates that the cylindrical part is braked within the exit cavity. If the entry switch detects the cylindrical part but the exit switch does not, it indicates that the cylindrical part is braked within both the entry and receiving cavities. In this case, the drain valve needs to be used to discharge liquid to brake the cylindrical part within the exit cavity. The braking position of the cylindrical part can be detected by the entry and exit switches, thereby coordinating with the drain valve to discharge liquid and brake the cylindrical part within the exit cavity. Therefore, the parts of the present invention have good compatibility.

[0035] 4. In the present invention, a transport device and method for cylindrical parts, the receiving section comprises multiple interconnected pipes with flanges facing each other between adjacent pipes. The flanges are connected by fixing screws, and a sealing ring is sandwiched between the flanges. In application, the number of pipes can be set as needed, i.e., the length of the receiving section is adjustable, thus the present invention has a high degree of customization. The flanges are sealed by the sealing ring, resulting in good sealing performance. Stable liquid pressure is maintained within the pipes, which is beneficial for achieving stable movement of the cylindrical parts. Therefore, the present invention provides stable movement.

[0036] 5. In the present invention, a transport device and method for cylindrical parts, an exhaust pipe is provided at one end of the receiving section near the taking section. The exhaust pipe is provided with an exhaust port and an exhaust cover. In application, the exhaust cover is first removed, and then liquid is introduced into the inlet chamber, the receiving chamber, and the taking chamber. During this process, the gas in the inlet chamber, the receiving chamber, and the taking chamber is discharged from the exhaust port. After the gas is discharged, the exhaust cover is then connected to the exhaust port to prevent liquid leakage from the exhaust port. Therefore, the exhaust effect of the present invention is better.

One end of the receiving cavity 21 is connected to one end of the entering cavity 11 of the entering section 1, which is also cylindrical. The end of the receiving section 2 away from the entering cavity 11 is connected to one end of the taking-out cavity 31 of the taking-out section 3, which is cylindrical. The other end of the taking-out section 3 is detachably connected to the cover plate 5.

[0054] A drain valve 4 is provided at the end of the receiving section 21 away from the inlet cavity 11. The drain valve 4 includes a drain valve core 41, and the movement stroke of the drain valve core 41 is to rotate within the drain valve 4.

[0055] The top of the drain valve core 41 is connected to one end of the drain valve stem 42, and the other end of the drain valve stem 42 extends out of the drain valve 4 and is connected to one end of the drain handle 43.

[0056] An inlet ball valve 12 is provided at one end of the inlet section 3. The middle part of the inlet ball valve 12 includes an inlet valve core 121. The movement stroke of the inlet valve core 121 is to rotate within the inlet ball valve 12.

[0057] The top of the inlet valve core 121 is connected to one end of the inlet valve stem 122, and the other end of the inlet valve stem 122 extends out of the top of the inlet ball valve 12 and is connected to one end of the inlet handle 123.

[0058] An entry switch 22 is provided on the end of the receiving section 2 near the entry section 1, and an exit switch 23 is provided on the end of the receiving section 2 near the exit section 3.

[0059] The entry switch 22 is a metal sensor, and the exit switch 23 is a metal sensor.

[0060] The entry switch 22 is a Hall sensor or a capacitive sensor, and the exit switch 23 is a Hall sensor or a capacitive sensor.

[0061] The receiving section 2 includes multiple pipes 24 connected in sequence. The flanges 25 of two adjacent pipes 24 face each other and are connected by fixing screws 26. A sealing ring 27 is sandwiched between the flanges 25 of two adjacent pipes 24.

[0062] The receiving section 2 is connected to a vertically upward exhaust pipe 6 at one end near the taking section 3. One end of the exhaust pipe 6 is connected to one end of the receiving cavity 21. An exhaust valve 61 is provided on the exhaust pipe 6.

[0063] The exhaust valve 61 includes an exhaust port 62, the opening of which faces upward, and an exhaust cover 63 is detachably connected to the exhaust port 62.

[0064] A method of using a transport device suitable for cylindrical parts, the method comprising the following steps:

[0065] Step 1: First connect the cover plate 5 to the extraction section 3, then introduce liquid into the inlet chamber 11, the receiving chamber 21, and the extraction chamber 31 so that the inlet chamber 11, the receiving chamber 21, and the extraction chamber 31 are all filled with the specified hydraulic pressure;

[0066] Step 2: The cylindrical part 7, which moves at a certain speed, first enters the inlet cavity 11. At this time, the outer surface of the cylindrical part 7 and the inner surface of the inlet cavity 11 form an annular gap 71. Therefore, the liquid will form an annular gap flow phenomenon. The liquid at the front end of the cylindrical part 7 will generate a larger pressure, while the liquid at the rear end of the cylindrical part 7 will have a smaller pressure. This pressure difference causes the cylindrical part 7 to gradually stop moving, thereby achieving the braking effect on the cylindrical part 7.

[0067] Step 3: Includes any one or a combination of the following:

[0068] If the cylindrical part 7 is located in the inlet cavity 11 or the receiving cavity 21 when it is braked: the receiving section 2 is close to the end of the take-out section 3 to discharge liquid. At this time, the high-pressure liquid moves towards the take-out section 3, and the cylindrical part 7 moves towards the take-out section 3 under the drive of the high-pressure liquid. After the high-pressure liquid is discharged, the cylindrical part 7 is braked in the take-out cavity 31.

[0069] If the cylindrical part 7 is located in the extraction cavity 31 when it is braked: remove the cover plate 5 and then remove the cylindrical part 7 from the extraction cavity 31.

[0070] Step 4: Repeat steps 2 and 3 in sequence until all cylindrical parts 7 have been transported.

[0071] The following are supplementary descriptions of the present invention:

[0072] The annular gap flow phenomenon described in this invention refers to the fluid flow phenomenon in the gap formed between two annular objects. It can be caused by the relative motion of the annular objects, by the pressure difference, or both. There is relative motion between the outer surface of the cylindrical part 7 and the receiving cavity 21 or the taking cavity 31, and an annular gap 71 is formed between the outer surface of the cylindrical part 7 and the receiving cavity 21 or the taking cavity 31, thus generating an annular gap flow phenomenon. At this time, a pressure difference will be generated on both sides of the cylindrical part 7 to brake the cylindrical part 7. Annular gap flow has wide applications in hydraulic systems, mechanical lubrication, and mine ventilation.

[0073] Example 1:

[0074] Please see Figure 1 — Figure 13 A transport device suitable for cylindrical parts is disclosed. The device includes an entry section 1, a receiving section 2, and a take-out section 3. The middle part of the receiving section 2 is a receiving cavity 21, which is cylindrical. One end of the receiving cavity 21 is connected to one end of the entry cavity 11 of the entry section 1, which is also cylindrical. The end of the receiving section 2 away from the entry cavity 11 is connected to one end of the take-out cavity 31 of the take-out section 3, which is also cylindrical. The other end of the take-out section 3 is detachably connected to a cover plate 5. A drain valve 4 is provided at the end of the receiving section 21 away from the entry cavity 11. The drain valve 4 includes a drain valve core 41, which rotates within the drain valve 4. The top of the drain valve core 41 is connected to one end of a drain valve rod 42, and the other end of the drain valve rod 42 extends out of the drain valve 4 and is connected to one end of a drain handle 43.

[0075] A method of using a transport device suitable for cylindrical parts, the method comprising the following steps:

[0076] Step 1: First connect the cover plate 5 to the extraction section 3, then introduce liquid into the inlet chamber 11, the receiving chamber 21, and the extraction chamber 31 so that the inlet chamber 11, the receiving chamber 21, and the extraction chamber 31 are all filled with the specified hydraulic pressure;

[0077] Step 2: The cylindrical part 7, which moves at a certain speed, first enters the inlet cavity 11. At this time, the outer surface of the cylindrical part 7 and the inner surface of the inlet cavity 11 form an annular gap 71. Therefore, the liquid will form an annular gap flow phenomenon. The liquid at the front end of the cylindrical part 7 will generate a larger pressure, while the liquid at the rear end of the cylindrical part 7 will have a smaller pressure. This pressure difference causes the cylindrical part 7 to gradually stop moving, thereby achieving the braking effect on the cylindrical part 7.

[0078] Step 3: Includes any one or a combination of the following:

[0079] If the cylindrical part 7 is located in the inlet cavity 11 or the receiving cavity 21 when it is braked: the receiving section 2 is close to the end of the take-out section 3 to discharge liquid. At this time, the high-pressure liquid moves towards the take-out section 3, and the cylindrical part 7 moves towards the take-out section 3 under the drive of the high-pressure liquid. After the high-pressure liquid is discharged, the cylindrical part 7 is braked in the take-out cavity 31.

[0080] If the cylindrical part 7 is located in the extraction cavity 31 when it is braked: remove the cover plate 5 and then remove the cylindrical part 7 from the extraction cavity 31.

[0081] Step 4: Repeat steps 2 and 3 in sequence until all cylindrical parts 7 have been transported.

[0082] Example 2:

[0083] The basic content is the same as in Example 1, except that:

[0084] Please see Figure 1 — Figure 10 The entry section 3 is provided with an entry ball valve 12 at one end. The middle part of the entry ball valve 12 includes an entry valve core 121. The movement stroke of the entry valve core 121 is to rotate within the entry ball valve 12. The top of the entry valve core 121 is connected to one end of the entry valve stem 122. The other end of the entry valve stem 122 extends out of the top of the entry ball valve 12 and is connected to one end of the entry handle 123.

[0085] In application, when transporting cylindrical part 7, rotate the entry handle 123, which in turn drives the entry valve stem 122 to rotate. Then, the entry valve stem 122 drives the entry valve core 121 to rotate, so that the cavity inside the entry valve core 121 is connected to one end of the entry cavity 11, thus opening the entry cavity 11. When closing the entry cavity 11, rotate the entry handle 123, which in turn drives the entry valve stem 122 to rotate. Then, the entry valve stem 122 drives the entry valve core 121 to rotate, thus disconnecting the cavity inside the entry valve core 121 from the entry cavity 11.

[0086] Example 3:

[0087] The basic content is the same as in Example 1, except that:

[0088] Please see Figure 1 — Figure 9 An entry switch 22 is provided at the end of the receiving section 2 near the entry section 1, and an exit switch 23 is provided at the end of the receiving section 2 near the exit section 3. The entry switch 22 is a metal sensor, and the exit switch 23 is a metal sensor. The entry switch 22 is a Hall effect sensor or a capacitive sensor, and the exit switch 23 is a Hall effect sensor or a capacitive sensor.

[0089] In application, if the entry switch 22 does not detect the cylindrical part 7, the cylindrical part 7 has not yet entered the entry cavity 11; if the entry switch 22 detects the cylindrical part 7, the cylindrical part 7 has entered the entry cavity 11; if the removal switch 23 does not detect the cylindrical part 7, the cylindrical part 7 is braked in the receiving cavity 21 or the entry cavity 11. At this time, the cylindrical part 7 needs to be moved to the removal cavity 31, so the drain valve 4 discharges the liquid. Therefore, the high-pressure liquid will drive the cylindrical part 7 to move into the removal cavity 31; if the removal switch 23 detects the cylindrical part 7, the cylindrical part 7 is braked in the removal cavity 31. Then, the cover plate 5 can be opened to remove the cylindrical part 7.

[0090] Example 4:

[0091] The basic content is the same as in Example 1, except that:

[0092] Please see Figure 1 — Figure 13 The receiving section 2 includes multiple pipes 24 connected in sequence. The flanges 25 of two adjacent pipes 24 face each other and are connected by fixing screws 26. A sealing ring 27 is sandwiched between the flanges 25 of two adjacent pipes 24.

[0093] In application, multiple pipes 24 are connected sequentially so that the flanges 25 of adjacent pipes 24 are facing each other. Then, fixing screws 26 are inserted sequentially into the threaded holes of the flanges 25 to fix the two flanges 25, thereby achieving the effect of fixing the two adjacent pipes 24. A sealing ring 27 is sandwiched between adjacent flanges 25 to seal and prevent liquid leakage between the flanges 25. The number, diameter and other parameters of the pipes 24 can be set as needed.

[0094] Example 5:

[0095] The basic content is the same as in Example 1, except that:

[0096] Please see Figure 1 — Figure 13 The receiving section 2 is connected to a vertically upward exhaust pipe 6 at one end near the taking section 3. One end of the exhaust pipe 6 is connected to one end of the receiving cavity 21. An exhaust valve 61 is provided on the exhaust pipe 6. The exhaust valve 61 includes an exhaust port 62, the opening of which faces upward. An exhaust cover 63 is detachably connected to the exhaust port 62.

[0097] In application, before introducing liquid into the inlet chamber 11, receiving chamber 21, and take-out chamber 31, first connect the cover plate 5 to the take-out section 3, then open the exhaust cover 63 to connect the exhaust port 62 to the outside. Then, introduce liquid into the inlet chamber 11, receiving chamber 21, and take-out chamber 31. At this time, the gas in the inlet chamber 11, receiving chamber 21, and take-out chamber 31 flows upward along the exhaust pipe 6 and the exhaust port 62. After the gas in the inlet chamber 11, receiving chamber 21, and take-out chamber 31 is exhausted, connect the exhaust cover 63 to the exhaust port 62 to close the exhaust port 62. Then, continue to introduce liquid into the inlet chamber 11, receiving chamber 21, and take-out chamber 31 until the liquid reaches the specified pressure.
