[0002] High-pressure hoses are used for mine hydraulic supports, oil field development, engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and mechanized and automated hydraulic systems in various industrial sectors to transport petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel, lubricating oil) and water-based liquids (such as emulsions, oil-water emulsions, water) with a certain pressure and temperature and liquid transmission pipelines. High-pressure oil pipes are mainly divided into high-pressure steel wire braided oil pipes and high-pressure steel wire wound oil pipes according to the manufacturing process.

[0003] Existing high-pressure hoses are usually flange-jointed when in use, and multiple bolts need to be rotated and fixed one by one during flange jointing, which not only wastes time and effort for workers, but also leads to low efficiency during jointing.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0022] See also Figures 1 to 5 The utility model provides a high-pressure hose for oil mining, which includes a pipe body 1, and connecting flanges 2 are fixedly installed at both ends of the pipe body 1, and each of the connecting flanges 2 is provided with a plurality of annularly distributed threaded through holes 2a, and the threaded through holes 2a corresponding to the two connecting flanges 2 are coaxially arranged, and any one of the connecting flanges 2 is provided with a docking assembly 3, and the docking assembly 3 includes a screw 31 and an inner gear ring 33, and the screw 31 is provided with a plurality of screws, and the plurality of screws 31 are respectively inserted into the connecting flanges 2 The threaded through hole 2a is opened and threadedly connected with the threaded through hole 2a, and a gear 32 is fixedly installed on each of the screw rods 31, and the internal gear ring 33 is meshed and connected with each gear 32. A plurality of annularly distributed protective components 4 are arranged between the two connecting flanges 2, and the protective components 4 include a steel wire 41, and the two ends of the steel wire 41 are respectively fixedly embedded on the opposite disk surfaces of the two connecting flanges 2, and a plurality of rotatably connected and equidistantly distributed rubber sleeves 42 are installed on the steel wire 41, and a gap is left between the rubber sleeve 42 and the outer tube surface of the tube body 1.

[0023] It should be noted that: when the pipe body 1 of the high-pressure rubber hose is connected, the connecting flange 2 with the docking assembly 3 installed on the pipe body 1 is docked with the connecting flange 2 on the other pipe body 1 without the docking assembly 3, and the threaded through holes 2a on the two connecting flanges 2 are kept coaxially arranged. After completion, the inner gear ring 33 is rotated. Since the inner gear ring 33 is meshed and connected with the gears 32 on each screw rod 31, the inner gear ring 33 can drive each screw rod 31 to be synchronously screwed along the threaded through hole 2a, so that each screw rod 31 is threadedly fixedly connected with the connecting flange 2 on the docking pipe body 1. The two high-pressure rubber hoses can be quickly fixed through the docking assembly 3, which greatly improves the work efficiency. At the same time, since each The gears 32 on each screw rod 31 are meshed and connected with the inner gear ring 33, so that when the high-pressure hose vibrates and causes a certain screw rod 31 to reverse, the screw rod 31 with the reverse tendency is restricted by the remaining screw rods 31, thereby greatly reducing the reverse driving force of the screw rod 31 with the reverse tendency; since a steel wire 41 is provided on the outside of the high-pressure hose, and a rubber sleeve 42 is rotatably connected to the steel wire 41, when a falling object falls on the tube body 1, the steel wire 41 and the rubber sleeve 42 can reduce the impact force of the falling object on the tube body 1, and the falling object can quickly roll down along the rubber sleeve 42, and at the same time, the rubber sleeve 42 will be driven to rotate after being hit, further increasing the falling speed of the falling object.

[0024] The end faces of the gear 32 are fixedly engaged with the limit plates 321, and the inner gear ring 33 is located on the gear 32 between the two limit plates 321, thereby avoiding the hidden danger of the inner gear ring 33 slipping off the gear 32 due to side sliding;

[0025] A knob ring 34 is fixedly mounted on the inner gear ring 33 to facilitate the staff to rotate the inner gear ring 33;

[0026] Among them, an insertion groove 2b is provided on the connecting flange 2 at one end of the tube body 1, and an elastic rubber tube 21 is fixedly embedded on the connecting flange 2 at the other end of the tube body 1, and the elastic rubber tube 21 is interference fit with the insertion groove 2b. When the two tube bodies 1 are docked, the elastic rubber tube 21 is inserted into the insertion groove 2b provided on the connecting flange 2 on the adjacent tube body 1. Since the elastic rubber tube 21 is interference fit with the insertion groove 2b, the sealing of the connection between the two high-pressure rubber hoses is greatly improved.

[0027] The working principle of the high-pressure hose for oil mining provided by the utility model is as follows:

[0028] When connecting the pipe body 1 of the high-pressure rubber hose, the connecting flange 2 with the docking assembly 3 installed on the pipe body 1 is docked with the connecting flange 2 on the other pipe body 1 without the docking assembly 3, and the threaded through holes 2a on the two connecting flanges 2 are kept coaxially arranged. After completion, the inner gear ring 33 is rotated. Since the inner gear ring 33 is meshed and connected with the gears 32 on each screw rod 31, the inner gear ring 33 can drive each screw rod 31 to be synchronously screwed along the threaded through hole 2a. Therefore, each screw rod 31 is threadedly fixedly connected with the connecting flange 2 on the docking pipe body 1. The two high-pressure rubber hoses can be quickly fixed through the docking assembly 3, which greatly improves the work efficiency. At the same time, since each screw rod 3 The gears 32 on 1 are all meshed and connected with the inner gear ring 33, so that when the high-pressure hose vibrates and causes a certain screw 31 to reverse, the screw 31 with the reverse tendency is restricted by the remaining screws 31, so the reverse driving force of the screw 31 with the reverse tendency is greatly reduced. Since a steel wire 41 is arranged on the outside of the high-pressure hose, and a rubber sleeve 42 is rotatably connected to the steel wire 41, when a falling object falls on the pipe body 1, the steel wire 41 and the rubber sleeve 42 can reduce the impact force of the falling object on the pipe body 1, and the falling object can roll down quickly along the rubber sleeve 42, and the rubber sleeve 42 will also be driven to rotate after being hit, further improving the falling speed of the falling object.
