[0024] The present patent application is further described below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1-5As shown, a high-pressure hose hanging device includes a fixing platform 1 welded to the platform deck and a clamp 5 located on the outside of the platform, the clamp 5 includes a first tube body 51 and a second tube body 52, the first tube body 51 and the second tube body 52 together form a cylindrical structure, the first tube body 51 is welded to the fixing platform 1, two groups of first pin shaft orifice plates 53 are symmetrically provided on the outer wall of the first tube body 51, and two second pin shaft orifice plates 54 are correspondingly provided on the outer wall of the second tube body 52, the first pin shaft orifice plates 53 and the corresponding second pin shaft orifice plates 54 are connected into a whole by a pin shaft 6, and the flange joint 2 of the high-pressure hose 7 is clamped in the cylindrical structure.

[0026] In the above technical solution, if Figure 1 As shown, the high-pressure hose suspension device consists of a fixing platform 1 and a clamp 5. The fixing platform 1 is welded on the platform deck to fix the suspension device on the platform. Figure 2 As shown, the clamp 5 is composed of a first tube body 51 and a second tube body 52. ​​The first tube body 51 and the second tube body 52 are connected to form a cylindrical structure by a first pin hole plate 53, a second pin hole plate 54, and a pin 6. The cylindrical structure is used to fasten the flange joint 2 of the high-pressure hose 7. During use, the fixing platform 1 is first welded to the platform deck, and one side of the first tube body 51 and the second tube body 52 are connected together by the pin 6. At this time, the first tube body 51 and the second tube body 52 are in a hinged state. Then, the high-pressure hose 7 is hoisted and lowered. After the flange joint 2 of the high-pressure hose 7 is lowered into place, the first tube body 51 and the second tube body 52 are closed and the other sides of the first tube body 51 and the second tube body 52 are connected together by the pin 6. This clamps the flange joint 2 of the high-pressure hose 7 within the cylindrical structure, thereby suspending and fixing the high-pressure hose 7. The clamp 5 of the present invention achieves rapid fixing and suspension of the high-pressure hose 7, has a simple structure, and is easy to install and remove.

[0027] In another technical solution, Figure 2 As shown, the fixed platform 1 includes a symmetrically arranged top plate 11 and a bottom plate 12, and the top plate 11 and the bottom plate 12 are fixedly connected to the outer side wall of the first tube body 51. The top plate 11 and the bottom plate 12 are connected into a whole through multiple side plates 13, and multiple side plates 13 are symmetrically arranged on both sides of the top plate 11 and the bottom plate 12. A reinforced rectangular tube 14 is welded in the cavity formed by the top plate 11, the bottom plate 12 and the side plates 13; and a lifting ear 15 is welded on the top plate 11.

[0028] In this technical solution, the operating environment of the offshore platform is harsh and the weight of the hose is very heavy. When operating on the offshore platform, a strong impact force and violent shaking will be generated on the suspension device, which may cause fatigue fracture of the suspension device. Therefore, the present invention welds a reinforced rectangular tube 14 in the cavity structure formed by the top plate 11, the bottom plate 12, and the side plate 13 to improve the overall strength of the fixed platform 1 and avoid fatigue fracture of the suspension device affecting the platform operation. The lifting lug 15 is used to lift the fixed platform 1 to the position to be welded.

[0029] In another technical solution, Figure 3 As shown, a clamping plate 21 is integrally formed on the outer wall of the flange joint 2 , and the clamping plate 21 is horizontally arranged. The length of the clamping plate 21 is greater than the inner diameter of the clamp 5 .

[0030] In the present technical solution, the clamping plate 21 can facilitate the tightening operation of the high-pressure hose 7. Specifically: when hoisting and lowering the high-pressure hose 7, when the clamping plate 21 contacts the first tube body 51 or the second tube body 52, it means that the high-pressure hose 7 is lowered into place, thereby reminding the staff to close the first tube body 51 and the second tube body 52. ​​After the first tube body 51 and the second tube body 52 are closed, since the length of the clamping plate 21 is larger than the inner diameter of the cylindrical structure, the high-pressure hose 7 can be located in the cylindrical structure through the clamping plate 21 to ensure the stability of the position of the high-pressure hose 7 during the tightening operation and prevent the high-pressure hose 7 from slipping into the sea. At the same time, since the clamping plate 21 is set horizontally, the horizontality of the high-pressure hose 7 during tightening can also be ensured, thereby ensuring the tightening effect.

[0031] In another technical solution, the flange end of the flange joint 2 is connected to a rotating movable joint 3, and the rotating movable joint 3 includes a flange direct joint 31 connected to the flange end and a flange bent joint 32 rotatably connected to the flange direct joint 31, and a flange lifting ear 33 is provided on the top surface of the flange bent joint 32.

[0032] In this technical solution, during offshore operations, the high-pressure hose 7 needs to be connected to the pipeline on the operating platform through a connector. If the connector is fixed to the flange joint 2 of the high-pressure hose 7, when the high-pressure hose 7 is seated in the clamp 5, if it twists, the connector will rotate, causing the docking port of the connector to face the outside of the platform, thereby affecting the connection between the connector and the pipeline. In addition, since the high-pressure hose 7 is extremely heavy, if it is adjusted on site, the safety risk is high. Therefore, if Figure 4As shown, the present invention provides a rotating movable joint 3 on the flange joint 2. If the high-pressure hose 7 twists, after the high-pressure hose 7 is fixed, the flange elbow joint 32 can be rotated so that the docking port of the flange elbow joint 32 faces the inside of the platform, facilitating the connection of the high-pressure hose 7 to the high-pressure pipeline. During use, the rotating movable joint 3 can be first connected to the flange joint 2 of the high-pressure hose 7, and then the entire high-pressure hose 7 can be hoisted into the clamp 5 via the flange lifting lug 33 to secure and suspend the high-pressure hose 7. The flange straight joint 31 and the flange elbow 32 are connected by steel balls to achieve the rotation effect.

[0033] In another technical solution, a telescopic bracket 4 is vertically installed on the top plate 11 .

[0034] In this technical solution, if Figure 1 As shown, the telescopic bracket 4 is used to support the high-pressure pipeline and adjust the height of the pipeline, which facilitates the docking operation between the high-pressure pipeline and the flange elbow 32. The telescopic bracket 4 consists of a telescopic part and a support plate. The support plate is fixed to the top of the telescopic part. The telescopic part of this application can be a screw with threads at both ends, one end is positively buckled and the other end is reversed. When rotating, the height above is adjusted. The support plate is an arc-shaped plate with the opening direction vertically upward. The arc-shaped plate can improve the stability of the telescopic bracket 4 when supporting the high-pressure pipeline.

[0035] In another technical solution, Figure 2 As shown, a tray 55 is welded to the outer side wall of the second tube body 52 away from the first tube body 51 , and the tray 55 horizontally extends out of the flange joint 31 .

[0036] In this technical solution, the tray 55 is used to collect parts that fall due to loosening during the operation to prevent the parts from falling into the sea.

[0037] In another technical solution, a rectangular limit block 61 is welded to one end of the pin shaft 6, and a safety pin hole is opened at the other end of the pin shaft 6, and a safety pin 62 is arranged in the safety pin hole.

[0038] In this technical solution, if Figure 5 As shown, the rectangular limit block 61 and the safety pin 62 are used to limit the two ends of the pin shaft 6, so that the pin shaft 6 is locked on the first pin shaft hole plate 53 and the second pin shaft hole plate 54 and is not easy to fall off.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
