Description

Technical Field

[0001] The utility model belongs to the technical field of grease filling for the oil storage tank of the automatic lubricating pump of a wind turbine unit, and particularly relates to a butt-joint device between an oil filling pump oil storage tank and an electric oil injector. Background Technique

[0002] Grease filling for the oil storage tank of the automatic lubricating pump of a wind turbine unit is a project that needs to be carried out during each annual maintenance. Taking the lubricating pump with the Lincoln brand model P203-8XBF-1K6-24-1A1.01 as an example, there are two oil injection holes in the pump body. One is a traditional grease gun oil injection hole, and the other is a Lincoln direct push oil gun oil injection hole. Currently, the method of injecting grease by using the direct push oil gun independently developed by the Lincoln manufacturer is generally adopted.

[0003] Due to the relatively compact structure of the wind power generating unit, affected by the installation position of the pump body and the temperature, etc., it takes time and effort during grease injection, and the efficiency is extremely low, seriously affecting the maintenance work efficiency, increasing the unit shutdown time, and affecting the unit availability. Therefore, there is room for improvement in actual use. Content of the Utility Model

[0004] The purpose of the utility model is to provide a butt-joint device between an oil filling pump oil storage tank and an electric oil injector to solve the problem of low working efficiency existing in the application of the direct push oil gun oil injection method on a wind turbine unit as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A butt-joint device between an oil filling pump oil storage tank and an electric oil injector includes a high-pressure rubber hose, with an oil injection hole adapter and a lubrication point adapter connected to both ends respectively; internal threads are provided on the inner walls of the oil injection hole adapter and the lubrication point adapter. During use, the oil injection hole adapter is connected to the direct push oil gun oil injection hole, and the lubrication point adapter is connected to the oil injector, so as to achieve the purpose of electric oil injection; a sealing assembly is provided in two groups and is respectively located inside the oil injection hole adapter and the lubrication point adapter. Through the sealing assembly, it can ensure that the oil injection hole adapter and the lubrication point adapter are hermetically connected during installation, avoiding the phenomenon of grease leakage; the sealing assembly includes a seal, which is sleeved on the end parts of the external structures, namely the direct push oil gun oil injection hole and the electric oil injector. A hole is opened in the center of the seal, and this hole is in communication with the oil injection hole adapter, the high-pressure rubber hose, and the lubrication point adapter to ensure the normal injection of lubricating grease; a connecting piece is fixed on the inner bottom end surfaces of the oil injection hole adapter and the lubrication point adapter, and this connecting piece is connected to the seal to achieve the installation of the seal and ensure normal use in the later stage.

[0006] Preferably, the seal includes a sealing collar which has a curved surface area threadedly connected to the inner walls of the oil injection hole adapter and the lubrication point adapter, and a flat surface area that fits against the inner end faces of the oil injection hole adapter and the lubrication point adapter. An integral retaining ring is provided on the inner wall of the curved surface area of the sealing collar. When the oil injection hole adapter, the lubrication point adapter are connected to the corresponding external equipment, the connector of the external equipment will be screwed into the inside of the sealing collar and abutted against the retaining ring. At this time, the retaining ring will deform, and the connection is sealed through the deformation and bending.

[0007] Preferably, the retaining ring extends obliquely towards the flat surface area of the sealing collar. This setting direction facilitates the screwing-in of the structure of the external equipment. The diameters of the sealing collars in the oil injection hole adapter and the lubrication point adapter are not equal.

[0008] Preferably, concentric ring grooves are provided on the outer surface of the flat surface area of the sealing collar, and convex rings that are snapped into the corresponding ring grooves are respectively fixed on the inner end faces of the oil injection hole adapter and the lubrication point adapter, so as to limit the position of the sealing collar and prevent displacement.

[0009] Preferably, a plurality of functional components are also sleeved on the surface of the high-pressure rubber hose. The functional component includes a sleeved component and a support component. The sleeved component is installed at both ends of the support component. The support component limits the bending angle of the high-pressure rubber hose, so that it can be better connected according to actual needs. When the functional component is not needed, it can also be easily disassembled.

[0010] Preferably, the sleeved component is a sleeve ring which has a notch. The high-pressure rubber hose is sleeved and disassembled through the notch. Two sleeve rings are provided in each group of functional components and are located at both ends of the support component.

[0011] Preferably, the support component is a plurality of metal sheets. The end faces of the metal sheets are arc-shaped and fit against the outer surface of the high-pressure rubber hose. When it is necessary to connect the high-pressure rubber hose at a specific bending angle, the metal sheets can be bent, and the metal sheets can drive the high-pressure rubber hose to maintain its shape at a specific angle. This bending method can also be applied to the daily storage of the high-pressure rubber hose.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] Through the design of the present utility model, the oil injection hole of the lubricating pump direct push oil gun is docked with the electric oil injector used in construction machinery. During use, it can not only achieve the purpose of electric oil injection, improve work efficiency, but also reduce the shutdown and maintenance time of the unit, reduce the labor intensity of personnel, and improve the deficiencies in the prior art.

[0026] A seal is sleeved on the external structure, namely the oil injection hole of the direct-push oil gun and the end of the electric oil injector. A hole is opened in the center of the seal, and this hole is in communication with the oil injection hole adapter 101, the high-pressure hose 100, and the lubrication point adapter 102 to ensure the normal injection of lubricating grease.

[0027] A connecting piece is fixed on the inner bottom end surfaces of the oil injection hole adapter 101 and the lubrication point adapter 102. The connecting piece is connected to the seal to achieve the installation of the seal and ensure normal use in the later stage.

[0028] In this embodiment, preferably, the seal includes a sealing collar 103. The sealing collar 103 has a curved surface area that is threadedly connected to the inner walls of the oil injection hole adapter 101 and the lubrication point adapter 102, and a flat surface area that fits against the inner end faces of the oil injection hole adapter 101 and the lubrication point adapter 102. An integral retaining ring 103a is provided on the inner wall of the curved surface area of the sealing collar 103.
