Description

Technical Field

[0001] This utility model relates to the field of hydraulic pipeline technology, specifically to a leak-proof wind power hydraulic pipeline assembly. Background Technology

[0002] With the increasing demand for green energy in my country, wind power generation has become an important component. The proper functioning of the wind power hydraulic system is a fundamental prerequisite for ensuring the effective operation of the entire wind power system. The wind power hydraulic system primarily utilizes hydraulic oil to transmit pressure during operation. Hydraulic oil is generally transported via hydraulic pipes, and the oil supply terminals of hydraulic components typically require hydraulic pipe fittings for connection.

[0003] According to a wind power hydraulic hose assembly disclosed in the public notice (Announcement No.: CN216923581U), the above application can further improve the sealing performance of the connection between the hydraulic hose and the hydraulic connector, minimize hydraulic oil leakage, and protect the connection between the hydraulic hose and the hydraulic connector, which helps to extend the service life of the equipment.

[0004] However, in actual use, the existing hydraulic pipes and their joints usually withstand high oil pressure, but the pressure resistance at the connection is limited. This causes the soft hydraulic pipes to vibrate easily when subjected to the impact of hydraulic oil, resulting in loosening of the connection between the hydraulic pipes and their joints and causing hydraulic oil leakage. In view of this, we propose a leak-proof wind power hydraulic pipe assembly. Utility Model Content

[0005] The purpose of this utility model is to provide a leak-proof wind-electric hydraulic pipe assembly to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof pneumatic-hydraulic hose assembly, comprising a cylindrical shell, a threaded shell connected to the arc surface of the cylindrical shell, a hose fixedly installed on the side wall of the threaded shell, a fixing mechanism provided inside the threaded shell, and a promoting mechanism provided inside the threaded shell, the fixing mechanism comprising:

[0007] A connecting ring is fixedly installed on the arc surface of the cylindrical shell, a fixing ring is fixedly installed on the arc surface of the threaded shell, and a connector ring is fixedly installed at the end of the hose near the cylindrical shell.

[0008] A rubber sleeve is fixedly installed on the arc surface of the joint ring. A circular ring is provided inside the cylindrical shell, and a rubber ring is fixedly installed on the inner diameter of the circular ring.

[0009] Preferably, the promoting mechanism includes a mounting hole formed on the inner wall of the cylindrical shell, and a guide rod is fixedly mounted on the outer wall of the annulus.

[0010] Preferably, the guide rod is disposed inside the mounting hole, and the number of mounting holes is set to several, which are arranged in a circumferential array on the inner wall of the cylindrical shell.

[0011] Preferably, the end of the cylindrical shell near the threaded shell is provided with an installation groove, the shape of which is adapted to the shape of the annulus.

[0012] Preferably, the connecting ring and the fixing ring are detachably connected by bolts.

[0013] Preferably, the cylindrical shell has an external thread on the arc surface near the threaded shell, and the threaded shell has an internal thread on the inner wall near the cylindrical shell.

[0014] Preferably, the diameter of the end port of the connector ring near the shell is smaller than the end diameter of the connector ring, and the diameter of the connector ring is adapted to the diameter of the shell.

[0015] Compared with the prior art, this utility model provides a leak-proof wind-electric hydraulic pipe assembly, which has the following beneficial effects:

[0016] 1. This leak-proof wind-electric hydraulic hose assembly has a fixing mechanism that connects the threaded shell on the hose to the cylinder shell. The cylinder shell and the threaded shell can then be fixed a second time with bolts to ensure the stability of the joint. Next, the rubber sleeve on the joint ring is inserted into the inside of the ring, and the protrusion on the rubber sleeve squeezes the rubber ring to ensure the seal between the joint ring and the inside of the cylinder shell, thus forming a seal and ensuring the sealing performance at the joint. This prevents the hydraulic hose from loosening at the connection with the joint, which could cause hydraulic oil leakage.

[0017] 2. This leak-proof wind-electric hydraulic pipe assembly is equipped with a facilitating mechanism that allows the guide rod on the ring to be disassembled from the inside of the mounting hole. This, combined with the internal compression and limiting of the threaded shell, ensures the ring's fixation and facilitates replacement of the rubber ring after prolonged use due to corrosion. This also prevents the hydraulic pipe from loosening at its connection with the joint, thus preventing hydraulic oil leakage. Attached Figure Description

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a leak-proof wind-electric hydraulic pipe assembly, including a cylindrical shell 1, a threaded shell 5 connected to the arc surface of the cylindrical shell 1, a hose 2 fixedly installed on the side wall of the threaded shell 5, a fixing mechanism 3 and a promoting mechanism 4 are provided inside the threaded shell 5, and the fixing mechanism 3 includes a connecting ring 301, a fixing ring 302, a rubber sleeve 303, a circular ring 304, a rubber ring 305, and a joint ring 306.

[0024] In one embodiment of this utility model, a connecting ring 301 is fixedly installed on the arc surface of the cylindrical shell 1, a fixing ring 302 is fixedly installed on the arc surface of the threaded shell 5, a connector ring 306 is fixedly installed at one end of the hose 2 near the cylindrical shell 1, a rubber sleeve 303 is fixedly installed on the arc surface of the connector ring 306, a circular ring 304 is provided inside the cylindrical shell 1, and a rubber ring 305 is fixedly installed on the inner diameter of the circular ring 304.

[0025] In addition, the promoting mechanism 4 includes a mounting hole 401, which is formed on the inner wall of the shell 1. A guide rod 402 is fixedly mounted on the outer wall of the ring 304. The guide rod 402 is disposed inside the mounting hole 401. The number of mounting holes 401 is set to a plurality of them, which are arranged in a circumferential array on the inner wall of the shell 1.

[0026] In this embodiment of the invention, a mounting groove is provided at one end of the cylindrical shell 1 near the threaded shell 5, and the shape of the mounting groove is adapted to the shape of the ring 304. The connecting ring 301 and the fixing ring 302 are detachably connected by bolts. An external thread is provided on the arc surface of the cylindrical shell 1 near the threaded shell 5, and an internal thread is provided on the inner wall of the threaded shell 5 near the cylindrical shell 1. The diameter of the connector ring 306 at one end near the cylindrical shell 1 is smaller than the end diameter of the connector ring 306, and the diameter of the connector ring 306 is adapted to the diameter of the cylindrical shell 1. The arc surface of the rubber sleeve 303 is provided with several protruding rings, so that the rubber sleeve 303 compresses the rubber ring 305 to form a seal.

[0027] In this utility model, during use, the threaded shell 5 on the hose 2 is threadedly connected to the cylindrical shell 1. Then, the cylindrical shell 1 and the threaded shell 5 are fixed a second time with bolts to ensure the stability of the joint. Next, the rubber sleeve 303 on the joint ring 306 is inserted into the inside of the ring 304, so that the protrusion on the rubber sleeve 303 squeezes the rubber ring 305 to ensure the seal between the joint ring 306 and the inside of the cylindrical shell 1, forming a seal and thus ensuring the sealing performance at the joint, thereby preventing the hydraulic pipe from loosening at its joint connection and causing hydraulic oil leakage.

[0028] Furthermore, the guide rod 402 on the ring 304 can be removed from the inside of the mounting hole 401 and used in conjunction with the internal compression limit of the threaded shell 5 to ensure the fixation of the ring 304. This facilitates the replacement of the rubber ring 305 after long-term use due to corrosion, and prevents the hydraulic pipe from loosening at its connection with the connector, thus preventing hydraulic oil leakage.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
