The roller mounting seat 34 extends out from the inner wall side of the rotating cylinder 33, and a plurality of rollers 42 are mounted inside the roller mounting seat 34. The rollers 42 are cylindrical or conical, and the rollers 42 contact the steps 43 of the flange end to form a snap-fit ​​structure, so that the threaded end 31 and the flange end 32 are connected together. The rollers 42 are high-strength bearing rollers, which can withstand the large static load generated by the pipeline pressure. The self-tightening filler 35 and the first sealing ring 36 are installed at the connection between the inner wall of the threaded end 31 and the flange end 32 for sealing; The second sealing ring 37 is used for dustproof sealing between the rotating cylinder 33 and the fixed cover plate 41; the third sealing ring 38 is used for dustproof sealing between the rotating cylinder 33 and the left side of the threaded end 31, and the fourth sealing ring 39 is used for dustproof sealing on the right side; the fifth sealing ring 40 is used for dustproof sealing between the rotating cylinder 33 and the right side of the flange end 32; The first oil port 44 and the second oil port 45 are formed on the side of the rotating cylinder 33.

[0049] When using a new high-pressure hose winch of this embodiment, in specific use, first, the driving mechanism is started to provide rotational power for the drum 2. The drum 2, as the main load-bearing and transmission component of the hose 59, its rotation will drive the high-pressure pipe 3 and the hose 59 connected to the rotary joint 5 to perform winding or releasing operations. The design of the rotary joint 5 ensures the smooth transition of the hose 59 on the drum 2 and at the same time prevents the hose 59 from being twisted or damaged during the winding or releasing process. During the winding or releasing process of the hose 59, the first pipe arranging device 6 and the second pipe arranging device 7 play a key role. Specifically, the first pipe arranging device 6 is arranged vertically, and the second pipe arranging device 7 is arranged horizontally. The first pipe arranging device 6 is used for laying the hose 59 in the marine environment, and the second pipe arranging device 7 is used for laying the hose 59 on land; the adjusting assembly can change the longitudinal position and the lateral position of the first pipe arranging device 6, so as to ensure that the hose 59 can be precisely arranged according to the operation requirements, thereby solving the technical problem that when the hose winch used in the prior art adapts to the high requirements of the marine environment, it is often difficult to take into account the flexible application in the land environment and there are limitations in the scope of application.

[0050] The first pipe arranging device 6 of the present invention is arranged vertically, and the second pipe arranging device 7 is arranged horizontally, so that there are two pipe arranging modes. The newly added horizontal pipe arranging mode can be used for pipe arrangement on land.

[0052] When the winch is used for pipe laying on land, a pipe-carrying trolley 57 needs to be installed on the ground. There are third rollers 58 on the left and right sides where the pipe-carrying trolley 57 contacts the hose 59, and fourth rollers 60 are installed at the bottom, reducing the wear caused by the friction between the hose 59 and the ground. The fourth rollers 60 at the bottom of the pipe-carrying trolley 57 are equipped with locking devices, which can ensure that the pipe-carrying trolley does not move during pipe laying; The structure used by the rotary joint 5 makes it not easy to generate eccentricity during rotation, and the drum 2 runs more stably, thereby prolonging the service life of the sealing packing and reducing the maintenance cost.
