Description

Technical Field

[0001] The utility model relates to the technical field of hose devices, in particular to a high-pressure hose anti-dropping locking device. Background Art

[0002] High-pressure hoses, that is, metal hoses that can withstand high pressure, are often used for the injection of high-pressure gas or liquid in oil field production. At present, high-pressure metal hoses have been used to complete carbon dioxide injection work at the production site of Luxeng Company's carbon dioxide injection work.

[0003] During the on-site production process of the oil field, in order to meet the production needs, the injection pressure of carbon dioxide during the injection process can reach more than 20 MPa. In the process of connecting and disassembling the pipeline interface with the corresponding interface on the injection wellhead or tank truck, the residual pressure in the pipeline is easy to break the hose, or the gate is opened to release the pressure after the pipeline interface thread is deflected, which will cause the high-pressure metal hose to swing around and hit the bodies of on-site workers and production equipment, causing casualties and equipment damage, and posing a major safety hazard. Therefore, the problem of fixing high-pressure hoses is a technical problem that needs to be urgently solved in current oil field production. According to the inventor's search, in order to solve this type of problem, the following comparative cases exist in the currently disclosed prior art:

[0004] The Chinese utility model patent with the publication (announcement) number: CN210165052U and the application number: CN201920911604.X discloses an anti-pull-out device for a high-pressure hose, comprising a joint core, a hose body, and a sleeve, wherein the joint core and the hose body are respectively provided with a first channel and a second channel for fluid circulation, and the sleeve is provided with a third channel for the joint core and the hose body to access, and the joint core is provided with an annular positioning boss on the side away from the hose body, and an annular abutting boss is provided on one side of the positioning boss, and an alignment groove is provided between the positioning boss and the abutting boss, and a first bite tooth is provided on the side of the joint core facing the hose body, and the hose body comprises a co-extruded outer rubber layer, a steel wire layer and an inner rubber layer, and the outer rubber layer, the steel wire layer and the inner rubber layer are arranged in sequence in the axial direction on the outer edge of the hose body, and the anti-pull-out device for the high-pressure hose has a reasonable structure, is easy to install and position, and effectively prevents pull-out, and has high practical value;

[0005] The Chinese utility model patent with the publication (announcement) number: CN218935624U and the application number: CN202320031042.6 discloses an anti-slip high-pressure hose connector, including a hose connection mechanism and an anti-slip mechanism. The utility model has a simple structure, a compact design, and is easy to use. The two high-pressure hoses are connected to the guide tubes of the sleeve and the butt pipe respectively, and then the sleeve and the butt pipe are butted together, and the locking screw is connected to the fixed seat between the sleeve and the butt pipe, and the nut is used to limit the two to prevent them from slipping due to excessive pressure, and at the same time, the elastic force of the pressure spring is used to squeeze the nut to prevent it from loosening and falling off, thereby further preventing the sleeve and the butt pipe from loosening and improving the tightness of the connection between the two. The inner wall of the sleeve is concavely provided with a limiting groove, and the limiting groove is annular in structure, and one end of the butt pipe is limited and docked in the limiting groove, and the butt pipe is limited by the limiting groove to form a concave-convex structure, which further improves the sealing degree between the sleeve and the butt pipe;

[0006] The Chinese utility model patent with the publication (announcement) number: CN216407936U and the application number CN202122482512.4 discloses a high-pressure hose anti-slip device for mining, which belongs to the technical field of accessories for mining support equipment, including an anti-slip clamp, two anti-slip clamps, a ring gasket is provided between the two anti-slip clamps, an earring is fixedly provided on the outer side of the anti-slip clamp, a round ring chain is provided on one side of the anti-slip clamp, and D-type shackles are provided at both ends of the round ring chain, and the round ring chain is movably connected to the earring through one of the D-type shackles; fixing holes are provided at both ends of the anti-slip clamp, and fasteners are provided in the fixing holes, and the fasteners fix the two anti-slip clamps together. The utility model adopts a unique fastening method, which can keep the anti-slip clamp and the round ring chain in a fastened state even in the case of strong earthquake, high temperature and high pressure, and will not cause injuries caused by the collapse of the high-pressure hose, which can effectively ensure the safety of coal miners and equipment, and ensure the normal progress of coal mining while ensuring the life safety of underground workers;

[0007] The technical solutions of the above-mentioned disclosed technologies, the technical problems to be solved and the beneficial effects produced are all different from those of the present invention, or are in different technical fields or application scenarios, but all have certain problems. By improving the hose joint to enhance stability or by using a clamp chain to provide a protective limit, such a method is still insufficient as a protective measure for the hose, and it may still cause collapse and detachment resulting in casualties. For this reason, we propose a high-pressure hose anti-detachment locking device. Utility Model Content
