Description

Technical Field

[0001] The utility model relates to the technical field of test tooling, in particular to a high-pressure pipeline anti-loosening structure. Background Art

[0002] The hydraulic system provides the power source for the hydraulic external work, and is composed of a power station, oil pipes, etc. The power station consists of a protective cover, a diesel engine, a fuel tank, a valve group, an oil pump, a circulating cooling part, a filtration system, etc. In the foundation construction of offshore wind power installation, it is necessary to drive the steel pile into the seabed through a pile driver. After the steel pile is completely in the water, a pile driver needs to be put on the top. The pile driver hammers down through the pile driver to make the steel pile continue to sink to the designed height. The pile hammer is lifted and loosened by pressurizing the hydraulic oil through the hydraulic system. The hydraulic oil is transported to the inside of the pile hammer through the oil pipe. The inside of the pipe needs to withstand a high oil pressure of 220 bar, so the pile hammer and the hydraulic system need to be connected through a high-pressure oil pipe. At present, the high-pressure oil pipes are connected by threads to prevent the leakage of high-pressure oil, but the high-pressure oil pipes will wear and loosen during use, and there is a high risk of "collapse" during the pressurization process. When the hydraulic system is in long-term pressurized use, the interface of the high-pressure oil pipe is always under high pressure and there is also a risk of loosening. There is 200 bar pressure oil in the high-pressure oil pipe. Once it sprays out, the high-pressure oil pipe will swing and injure nearby people. Utility Model Content

[0023] See also Figure 1 and Figure 2 The technical solution of the utility model is described in detail below in conjunction with specific embodiments:

[0024] An embodiment of the utility model provides a high-pressure pipeline anti-loosening structure, including a first connecting unit and a second connecting unit, the first connecting unit includes a first socket 1 and a second socket 2; the second connecting unit includes a connecting rod 3, one end of the connecting rod 3 is fixedly connected to the first socket 1, and the other end of the connecting rod 3 is fixedly connected to the second socket 2; wherein the first socket 1 and the second socket 2 are respectively sleeved on the connecting head 41 of the adjacent high-pressure pipeline 4.

[0025] Therefore, the utility model connects the first socket 1 and the second socket 2 through the connecting rod 3, and the first socket 1 and the second socket 2 are respectively connected to the adjacent high-pressure pipelines 4. Therefore, on the basis of the connection of the connecting heads 41 of the adjacent high-pressure pipelines 4, a connecting structure arranged outside the high-pressure pipelines 4 is added, so that the connection of the adjacent high-pressure pipelines 4 is more firm and reliable. At the same time, when the joints of the adjacent high-pressure pipelines 4 are loose, the connecting rod 3 still plays a connecting role, and the strength of the connecting rod 3 is relatively large. When the internal pressure of the high-pressure pipeline 4 reaches 220 bar, even if the joints of the high-pressure pipeline 4 are loose, the two ends of the connecting rod 3 can still "pull" the high-pressure pipeline 4 through the first socket 1 and the second socket 2 to prevent the high-pressure pipeline 4 from "breaking" and swinging to injure people.

[0026] In one embodiment of the utility model, the first sleeve connector 1 and the second sleeve connector 2 both include a collar portion 11 and a locking portion 12. The collar portion 11 is an elastic member with a diameter of 70 mm to 100 mm, which is sleeved outside the high-pressure pipeline 4 and is tightly fixed to the high-pressure pipeline 4 through the locking portion 12. The elastic collar portion 11 can be adapted to high-pressure pipelines 4 of different diameters. After adaptation, the diameter of the collar portion 11 is fixed by the locking portion 12 so that it is tightly sleeved on the high-pressure pipeline 4.

[0027] In one embodiment of the utility model, the first sleeve 1 and the second sleeve 2 are respectively provided with a connecting protrusion 13, each connecting protrusion 13 is provided with a threaded hole, and a pair of threaded holes on the first sleeve 1 and the second sleeve 2 are coaxially provided and arranged parallel to the axial direction of the high-pressure pipeline 4. The connecting rod 3 is provided with threads, and the two ends of the connecting rod 3 respectively penetrate the threaded holes of the corresponding connecting protrusions 13 and are threadedly connected. The connecting rods 3 corresponding to the side of the pair of connecting protrusions 13 on the first sleeve 1 and the second sleeve 2 that are away from each other are respectively provided with a limiting nut 31. The limiting nut 31 is threadedly connected to the connecting rod 3 to prevent the connecting rod and the connecting protrusion 13 from loosening.

[0028] In one embodiment of the utility model, the first sleeve 1 and the second sleeve 2 are clamps. A connecting protrusion 13 is provided on the locking portion of each clamp, and the connecting protrusion 13 is protruded in a direction away from the collar portion 11 of the clamp. Anti-skid grooves 111 or anti-skid rubber pads are evenly provided on the inner side wall of the collar portion 11 of each clamp to prevent the clamp from sliding relative to the high-pressure pipeline 4.

[0029] In one embodiment of the present invention, the connectors 41 of adjacent high-pressure pipelines 4 are locked and connected by connecting nuts 42. The connectors 41 of adjacent high-pressure pipelines 4 are provided with limiting platforms 43 on both sides of the connecting nuts 42, respectively, for limiting the axial sliding of the first sleeve 1 and the second sleeve 2 to approach each other.

[0030] In summary, when the high-pressure pipeline 4, especially the high-pressure pipeline 4 of the hydraulic system, is in use, when the pressure in the pipe reaches 220 bar, the joint of the high-pressure pipeline 4 "breaks open" and swings out, causing danger and even casualties. The joints of adjacent high-pressure pipelines 4 are locked and connected by connecting nuts 42 to form a connector 41. The connector 41 is provided with a high-pressure pipeline anti-loosening structure of the utility model, which can solve the problem of the joint of the high-pressure pipeline 4 "breaking open" and swinging out. Specifically, the first socket 1 and the second socket 2 are respectively sleeved on the connector 41 of the adjacent high-pressure pipeline 4, and according to the diameter of the high-pressure pipeline 4, the diameter of the ring part 11 is adjusted to adapt to the diameter of the corresponding high-pressure pipeline 4, and then the ring part 11 is locked and fixed by the locking part 12 so that it is tightly sleeved outside the high-pressure pipeline 4. The connecting rod 3 passes through a pair of connecting protrusions 13 on the first sleeve 1 and the second sleeve 2 in sequence, and is connected by threaded fit, and finally, a limiting nut 31 is respectively provided on the connecting rod 3 corresponding to the ends of the pair of connecting protrusions 13 that are away from each other. The installation of the high-pressure pipeline anti-loosening structure on the connector 41 of the adjacent high-pressure pipeline 4 is completed, so that when the adjacent high-pressure pipeline 4 is connected through the connector 41, the axial connection is further reinforced by the connecting rod 3, which not only ensures the strength of the connection, but also when the connector 41 of the adjacent high-pressure pipeline 4 is loosened, the connecting rod 3 plays the role of "pulling" the high-pressure pipeline 4 to prevent the high-pressure pipeline 4 from "breaking open" and swinging to injure people. Ensure the safety of the operation.

[0031] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
