[0007] A steam trap is arranged at one end of the receiving section away from the inlet cavity, wherein the steam trap comprises a steam trap core, and the movement stroke of the steam trap core is rotation in the steam trap; The top of the steam trap core is connected to one end of the steam trap stem, and the other end of the steam trap stem is connected to one end of the steam trap handle after extending out of the steam trap.

[0008] An entry ball valve is provided at one end of the entry section, and the middle part of the entry ball valve includes an entry valve core, and the movement stroke of the entry valve core is to rotate in the entry ball valve; 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 of the top of the inlet ball valve and is connected to one end of the inlet handle.

[0015] A method for using a transport device for cylindrical parts, the method comprising the following steps: Step 1: first connect the cover plate to the extraction section, then introduce liquid into the entry chamber, the receiving chamber, and the extraction chamber, so that the entry chamber, the receiving chamber, and the extraction chamber are all at the specified hydraulic pressure; Step 2: The cylindrical part moving at a certain speed enters the entry cavity first. At this time, an annular gap is formed between the outer surface of the cylindrical part and the inner surface of the entry cavity, so the liquid will form an annular gap flow phenomenon. A larger pressure will be generated in the liquid at the front end of the cylindrical part, and the pressure in the liquid at the rear end of the cylindrical part is smaller. The pressure difference makes the cylindrical part gradually stop moving, thereby achieving a braking effect on the cylindrical part; Step 3: Include any one or combination of the following: If the cylindrical part is located in the entry cavity or the receiving cavity when being braked: the receiving section is made to discharge liquid at one end close to the extraction section.

After the high-pressure liquid is discharged, the cylindrical part is braked in the extraction cavity; If the cylindrical part is located in the removal chamber when braking: remove the cover plate again, and then remove the cylindrical part from the removal chamber.

[0016] Step 4: Repeat steps 2 and 3 in sequence until all cylindrical parts are transported.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. In a transport device and a method for using cylindrical parts of the present invention, the device comprises an entry section, a receiving section and a removal 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 removal cavity of the removal section. A drain valve is provided on the end of the receiving section, and a cover plate is detachably connected to the other end of the removal section. When used, the entry cavity, the receiving cavity and the removal cavity are first filled with liquid, and the liquid has a specified pressure, and then the cylindrical part is moved into the entry cavity at a certain speed, that is, there is relative movement between the cylindrical part and the entry cavity. The outer surface of the cylindrical part forms an annular gap with the inner surface of the entry cavity, so an annular gap flow phenomenon will occur at this time, which makes the pressure at the front end of the cylindrical part larger and the pressure at the rear end of the cylindrical part smaller, so the cylindrical part will gradually stop moving. If the cylindrical part is braked in the entry cavity or the receiving cavity, and then the steam trap is made to discharge liquid, at this time, the high-pressure liquid will drive the cylindrical part to move toward the steam trap, so the cylindrical part will eventually brake in the removal cavity; if the cylindrical part is braked in the removal cavity, the cover plate can be removed to remove the cylindrical part from the removal cavity. The advantages of the present invention also include: First point: The high-speed moving cylindrical parts are transported in the entry cavity, receiving cavity and extraction cavity. Compared with the existing technology, there is no need for the parts to return, so the transportation efficiency is higher; and after the entry section, receiving section and extraction section are manufactured, they can be used for a long time, that is, the cylindrical parts can be transported for a long time; Second point: brake the cylindrical part through the annular gap flow phenomenon, and then observe the braking position of the cylindrical part. If the cylindrical part brakes in the entry cavity or the receiving cavity, the high-pressure liquid is discharged through the steam trap, so the high-pressure liquid drives the cylindrical part to move to the receiving cavity, and then the cylindrical part brakes in the receiving cavity; if the cylindrical part brakes in the receiving cavity, open the cover plate and directly take out the cylindrical part; the cylindrical part is braked by the pressure difference generated by the annular gap flow phenomenon, so the braking process does not depend on other parts, making the device smaller in size; The third point: The final braking position of the cylindrical parts can be adjusted through the steam trap, so that the cylindrical parts finally reach the removal chamber, which ensures the transportation effect of the cylindrical parts; Therefore, the present invention has high conveying efficiency and better transportation effect on cylindrical parts.

[0018] 2. In a transportation device and a method for using cylindrical parts of the present invention, an entry ball valve is provided at one end of the entry section, an entry valve core is provided inside the entry ball valve, and the top of the entry valve core is connected to the entry valve stem and the entry handle in sequence. When in use, 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 be connected to the entry cavity or not connected to the entry cavity, that is, to achieve the effect of opening and closing the entry cavity; by rotating the entry handle, the opening and closing of the entry cavity can be achieved, so the operation is convenient, and compared with other opening and closing components, the size of the entry ball valve is small, so it can efficiently utilize space. Therefore, the present invention is easy to operate.

[0019] 3. In a transportation device and use method suitable for cylindrical parts of the present invention, an entry switch is provided on one end of the receiving section close to the entry section, and a removal switch is provided on one end of the receiving section close to the removal section. When in use, if both the entry switch and the removal switch detect the cylindrical part, it means that the cylindrical part is braked in the removal chamber. If the entry switch detects the cylindrical part, and the removal switch does not detect the cylindrical part, it means that the cylindrical part is braked in the entry chamber and the receiving chamber. At this time, the steam trap needs to discharge liquid to brake the cylindrical part in the removal chamber. The braking position of the cylindrical part can be detected by the entry switch and the removal switch, so as to cooperate with the steam trap to discharge liquid so that the cylindrical part is braked in the removal chamber. Therefore, the parts of the present invention have good compatibility.

[0020] 4. In the transport device and use method for cylindrical parts of the present invention, the receiving section includes a plurality of connected pipe bodies, the flanges between adjacent pipe bodies are opposite, the flanges are connected by fixing screws, and a sealing ring is sandwiched between the flanges. When used, the number of pipe bodies can be set as needed, that is, the length of the receiving section can be adjusted, so the degree of personalization of the present invention is high; the flanges are sealed by sealing rings, so the sealing performance is good, and the stable liquid pressure can be maintained in the pipe body, which is conducive to achieving a stable movement effect of the cylindrical parts. Therefore, the movement effect of the present invention is stable.

[0021] 5. In the transport device and use method for cylindrical parts of the present invention, an exhaust pipe is provided on one end of the receiving section close to the taking-out section, and an exhaust port and an exhaust cover are provided on the exhaust pipe. When in use, the exhaust cover is first removed, and then liquid is introduced into the entry cavity, the receiving cavity and the taking-out cavity. During this process, the gas in the entry cavity, the receiving cavity and the taking-out cavity is discharged from the exhaust port. After the gas is exhausted, the exhaust cover is connected to the exhaust port to prevent liquid from leaking from the exhaust port. Therefore, the exhaust effect of the present invention is better.

9. A transport device for cylindrical parts according to claim 8, characterized in that: The exhaust valve (61) comprises an exhaust port (62), the opening direction of the exhaust port (62) faces upward, and the exhaust port (62) is detachably connected to an exhaust cover (63).

10. A method for using the transport device for cylindrical parts according to claim 1, characterized in that: The method comprises the following steps: The first step is to connect the cover plate (5) to the removal section (3), and then introduce liquid into the entry chamber (11), the receiving chamber (21), and the removal chamber (31) so that the entry chamber (11), the receiving chamber (21), and the removal chamber (31) are all at a specified hydraulic pressure; Step 2: The cylindrical part (7) moving at a certain speed first enters the entry cavity (11). At this time, an annular gap (71) is formed between the outer surface of the cylindrical part (7) and the inner surface of the entry cavity (11). Therefore, the liquid forms an annular gap flow phenomenon. A relatively large pressure is generated in the liquid at the front end of the cylindrical part (7), while a relatively small pressure is generated in the liquid at the rear end of the cylindrical part (7). The pressure difference causes the cylindrical part (7) to gradually stop moving, thereby achieving a braking effect on the cylindrical part (7). Step 3: Include any one or combination of the following: If the cylindrical part (7) is located in the entry chamber (11) or the receiving chamber (21) when braking: the end of the receiving section (2) close to the removal section (3) discharges liquid. At this time, the high-pressure liquid moves toward the removal section (3), and the cylindrical part (7) moves toward the removal 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 removal chamber (31); If the cylindrical component (7) is located in the removal chamber (31) during braking: removing the cover plate (5) and then removing the cylindrical component (7) from the removal chamber (31); Step 4: The second and third steps are repeated in sequence until the transportation of all cylindrical parts (7) is completed.
