Description

Technical Field

[0001] The invention relates to the technical field of underwater oil tree electric hydraulic crossers, in particular to a pipe bending tool used for underwater oil tree electric hydraulic crossers. Background Art

[0002] The electro-hydraulic transmitter is a key component of the underwater oil tree, used for the electrical signal transmission, hydraulic power transmission and chemical injection of the underwater oil tree.

[0003] The carrier that completes the above functions is the hydraulic pipeline of the electro-hydraulic transmitter, which connects the external environment with the inside of the electro-hydraulic transmitter so that the electro-hydraulic transmitter can work. During the operation of the electro-hydraulic transmitter, the hydraulic pipeline needs to withstand the corresponding pressure, so the hydraulic pipeline is required to have a shape that can meet reasonable pressure.

[0004] At present, workers usually use ordinary pipe bender to make initial bends on hydraulic pipes, and then use manual bending to make secondary bends to determine the shape of the pipe. However, the standardization of manual pipe bending is low, and different workers have different bending strengths and angles for hydraulic pipes. Even the same worker cannot guarantee that the hydraulic pipes have exactly the same shape every time they are bent. This will cause the hydraulic pipes produced in batches to have no uniform shape, and some of them may even not meet the standard shape, and cannot bear the pressure when conveying hydraulic signals and chemicals, posing a safety hazard. Summary of the invention

[0005] The purpose of the present invention is to provide a pipe bending tool for an underwater oil tree electro-hydraulic crosser to solve the problems existing in the above-mentioned related technologies, and to be able to perform standardized bending on hydraulic pipelines, ensure that the bent hydraulic pipelines have good pressure-bearing performance, and improve the pipe bending efficiency.

[0006] To achieve the above object, the present invention provides the following solutions: The present invention provides a pipe bending tool for an underwater oil tree electro-hydraulic crosser, comprising a pipe bending tool body, a fixing mechanism and a rotating mechanism, wherein the pipe bending tool body is a cylindrical structure, and a bending guide rail is arranged on the pipe bending tool body, and the bending guide rail spirally surrounds the pipe bending tool body; the fixing mechanism is arranged on the pipe bending tool body, and the fixing mechanism can fix the first end of the hydraulic pipeline to the bending starting end of the bending guide rail; the rotating mechanism comprises a sleeve and a rotating rod, and the sleeve is rotatably sleeved on the pipe bending tool body, The inner side of the sleeve is connected to the bending guide rail through a guide assembly, and the guide assembly can move along the bending guide rail to enable the sleeve to move and rotate along the pipe bending tool body; the rotating rod is arranged between the sleeve and the bending starting end of the bending guide rail, one end of the rotating rod is fixedly connected to the sleeve, and the other end can move along the bending guide rail through a pulley, and a bending channel for the second end of the hydraulic pipeline to penetrate is formed between the pulley and the bending guide rail, so that the hydraulic pipeline can be bent along the bending guide rail.

[0007] Preferably, the bending guide rail is a semicircular groove structure, and a semicircular groove is provided on the circumferential surface of the pulley, so that the cross-sectional size of the bending channel matches the cross-sectional size of the hydraulic pipeline.

[0008] Preferably, the guide assembly includes a round head screw, which is radially penetrated on the sleeve and is slidably connected to the bent guide rail.

[0009] Preferably, the rotating mechanism further comprises a handle, and the handle is fixed to an end of the rotating rod away from the sleeve.

[0010] Preferably, the fixing mechanism includes a fixing block and a fastening screw, the fixing block is fixed on the pipe bending tool body at a position close to the bending starting end of the bending guide rail, and a fixing channel is formed between the fixing block and the bending starting end of the bending guide rail, the fastening screw is penetrated on the fixing block along the radial direction of the fixing channel, and the fastening screw can fix the first end of the hydraulic pipeline in the fixing channel.

[0014] Compared with the related art, the present invention has achieved the following technical effects: The present invention provides a pipe bending tool for an underwater oil production tree electro-hydraulic crosser, comprising a pipe bending tool body, a fixing mechanism and a rotating mechanism. The pipe bending tool body is provided with a bending guide rail, and the rotating mechanism comprises a sleeve and a rotating rod. When in use, the first end of the hydraulic pipeline is first fixed to the bending starting end of the bending guide rail through the fixing mechanism, and then the second end of the hydraulic pipeline is inserted into the bending channel formed between the pulley of the rotating rod and the bending guide rail. Then, the rotating rod is rotated, and the sleeve is driven to rotate by the rotating rod. At the same time, the inner side of the sleeve moves along the bending guide rail through the guide assembly, so that the sleeve moves and rotates along the pipe bending tool body, and then the pulley of the rotating rod moves synchronously along the bending guide rail.
