Abstract
Description
Technical Field
[0001] The invention relates to an oil pipe disassembly and assembly tool, in particular to a disassembly and assembly tool for high-pressure oil pipes. Background Art
[0002] In special circumstances, in order to meet functional requirements, the pipe interfaces at both ends of the oil pipe are arranged in reverse horizontally, but the oil pipe cannot be removed at this time. Especially when double-walled high-pressure oil pipes are used, the oil pipes are very rigid and have no elastic space. Existing disassembly and assembly tools cannot complete the disassembly and assembly smoothly, such as the return oil pipe disassembly and assembly tool disclosed in patent publication number CN206605426U, which includes a sleeve and a rotating arm. An axial through opening is provided on the side wall of the sleeve, allowing the return oil pipe to be laterally inserted into the sleeve. The shape of the inner wall of the sleeve corresponds to the shape of the locking nut of the return oil pipe, allowing the sleeve to be sleeved onto the locking nut. One end of the rotating arm is connected to one end of the sleeve, and the rotating arm is arranged to extend along the axial direction of the sleeve, driving the sleeve to rotate to rotate the locking nut for disassembly and assembly. Therefore, it is necessary to make the high-pressure oil pipe into an "Ω" oil pipe and use special tools to disassemble and assemble the oil pipe. Summary of the Invention
[0003] The object of the present invention is to provide a high-pressure oil pipe disassembly and assembly tool, which can stably and easily disassemble and assemble the "Ω" high-pressure oil pipe.
[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is: a high-pressure oil pipe disassembly and assembly tool, comprising an "Ω"-shaped high-pressure oil pipe, a U-shaped tube, and an external hexagonal round rod disassembly component, wherein the two U-shaped tubes are respectively sleeved on both sides of the "Ω"-shaped high-pressure oil pipe, and the two U-shaped tubes are connected by two external hexagonal round rod disassembly components, and the two U-shaped tubes are respectively connected to the left and right ends of the external hexagonal round rod disassembly components by threads.
[0005] Furthermore, the two U-shaped tubes are respectively threaded with left-handed and right-handed threads at the ends to form a U-shaped round rod with left-handed threads at both ends and a U-shaped round rod with right-handed threads at both ends.
[0006] Furthermore, two ends of the external hexagonal round rod disassembly component are respectively provided with left-hand and right-hand threads.
[0007] Furthermore, a small semicircular plate is welded inside the bottom of the U-shaped tube to support the straight section of the high-pressure oil pipe.
[0008] Furthermore, the arc surface of the semicircular small plate is adapted to the outer circular surface of the “Ω”-shaped high-pressure oil pipe.
[0009] Furthermore, the “Ω”-shaped high-pressure oil pipe is narrow at the top and wide at the bottom, and the entire high-pressure oil pipe has space for elastic deformation.
[0010] Furthermore, during disassembly and assembly, the two U-shaped tubes are respectively sleeved on both sides of the "Ω"-shaped high-pressure oil pipe, and two external hexagonal round rod disassembly parts are used to connect the U-shaped tube with left-handed threads at both ends and the U-shaped tube with right-handed threads at both ends through left and right threads.
[0011] Furthermore, when the external hexagonal round rod is screwed to disassemble the component, the threads at both ends are screwed into the U-shaped tube with left-hand threads and the U-shaped tube with right-hand threads, pressing the two ends of the "Ω"-shaped high-pressure oil pipe inward, causing the "Ω"-shaped high-pressure oil pipe to elastically deform inward, thereby meeting the requirements of disassembly and assembly of the high-pressure oil pipe.
[0012] The beneficial effects of the present invention are:
[0013] When pipe joints are placed at both ends, the high-pressure fuel pipe cannot be tightened or unscrewed. By shaping the high-pressure fuel pipe into an "Ω" shape, narrow at the top and wide at the bottom, the entire pipe will have room for elastic deformation. The high-pressure fuel pipe disassembly and assembly tool of the present invention can then be used to reliably and easily disassemble and assemble the "Ω"-shaped high-pressure fuel pipe.

[0016] Figure 3 This is a schematic diagram of the hexagonal round bar disassembly part. DETAILED DESCRIPTION
[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0018] like Figures 1 to 3 As shown, the high-pressure fuel pipe disassembly and assembly tool of the present invention cannot tighten or unscrew the high-pressure fuel pipe when the pipe joints are arranged at both ends. First, the high-pressure fuel pipe is formed into the following "Ω" shape: the "Ω"-shaped high-pressure fuel pipe 101 is narrow at the top and wide at the bottom. This will allow space for elastic deformation of the entire fuel pipe.
[0019] This disassembly and assembly tool comprises a U-shaped tube, a semicircular plate 4, and a hexagonal rod disassembly tool 1. The ends of the two U-shaped tubes are respectively tapped with left-hand and right-hand threads to form a U-shaped rod 2 with left-hand threads at both ends, and a U-shaped rod 3 with right-hand threads at both ends. The hexagonal rod disassembly tool 1 has left-hand and right-hand threads at both ends, respectively. A semicircular plate 4 is welded to the bottom of the U-shaped tube to support the straight section of the high-pressure oil pipe.
[0020] A semicircular plate 4 is welded to a U-shaped round rod 2 with left-handed threads at both ends and a U-shaped round rod 3 with right-handed threads at both ends.
[0021] During assembly and disassembly, a U-shaped round rod 2 with left-hand threads at both ends and a U-shaped round rod 3 with right-hand threads at both ends are respectively sleeved onto the two sides of the "Ω"-shaped high-pressure oil pipe 101. Then, an external hexagonal round rod disassembly member 1 is used to connect the U-shaped round rod 2 with left-hand threads and the U-shaped round rod 3 with right-hand threads at both ends via the left and right threads. When the external hexagonal round rod disassembly member 1 is tightened, the threads at both ends are screwed into the U-shaped round rod 2 with left-hand threads and the U-shaped round rod 3 with right-hand threads at both ends, pressing the two ends of the "Ω"-shaped high-pressure oil pipe 101 inward. This satisfies the assembly and disassembly requirements of the high-pressure oil pipe.
