As shown in the figure, Figure 1 The PPH pipeline locking tool provided by the embodiment, the PPH pipeline 100 is inserted into the pipeline joint 200, the PPH pipeline locking tool comprises a rack 1, a supporting piece 2, a pressure device 3 and a fusion device (not shown in the figure), the supporting piece 2 is placed on the rack 1, the supporting piece 2 has a clamping part for clamping the outer wall of the PPH pipeline 100 and an abutting part 25 for abutting the end face of the end of the PPH pipeline away from the pipeline joint 200, the pressure device 3 is fixedly connected to the rack 1, the pressure device 3 can apply pressure to the end face of the pipeline joint 200, and the fusion device can heat the PPH pipeline 100 and the pipeline joint 200.
[0034] The PPH pipeline locking tool in the embodiment can support the outer wall of the PPH pipeline 100 and abut the end face of the end of the PPH pipeline 100 away from the pipeline joint 200 after the PPH pipeline 100 is inserted into the pipeline joint 200 through the clamping part and the abutting part 25 of the supporting piece 2, the staff holds the supporting piece 2 so that the PPH pipeline 100 and the pipeline joint 200 are heated by the fusion device, the pressure device 3 applies pressure to the end face of the pipeline joint 200 to realize the connection and locking of the PPH pipeline 100 and the pipeline joint 200, the perpendicularity of the PPH pipeline 100 and the pipeline joint 200 is ensured, and the staff is prevented from being scalded.
[0035] As shown in the figure, Figure 1 The clamping part is an arc-shaped clamping surface, the arc-shaped clamping surface surrounds to form a clamping space for clamping the outer wall of the PPH pipeline 100, the arc-shaped clamping surface can be fitted with the outer wall of the PPH pipeline 100, so that the supporting piece 2 can more stably clamp the PPH pipeline 100, the PPH pipeline 100 is prevented from moving in the radial direction when the pressure device 3 applies pressure to the end face of the pipeline joint 200, and the perpendicularity of the PPH pipeline 100 and the pipeline joint 200 in the connection and locking is ensured.
[0036] Preferably, the different specifications of PPH pipelines 100 have different outer diameters, and all need to be connected and locked with the pipeline joint 200 to be normally used. In order to make the PPH pipeline locking tool applicable to PPH pipelines 100 of various specifications, the PPH pipeline locking tool comprises at least two supporting members 2, the arc-shaped clamping surfaces of each supporting member 2 are different in curvature, and one of the supporting members 2 is placed on the rack 1, so that one set of PPH pipeline locking tool can be used for PPH pipelines 100 of different specifications, thereby improving the versatility of the PPH pipeline locking tool. It should be noted that the number of supporting members 2 is not limited, and can be 2, 3, 4, or even more, as long as the arc-shaped clamping surface of the supporting member 2 is in close contact with the outer wall of the PPH pipeline 100. It can be understood that one supporting member 2 can only be applicable to one outer diameter specification of PPH pipeline 100.
[0037] As shown in FIG. 1, the PPH pipeline locking tool comprises a rack 1 and a supporting member 2, the supporting member 2 is fixedly connected to the rack 1, and the supporting member 2 has an arc-shaped clamping surface, the arc-shaped clamping surface is formed on the side surface of the supporting member 2 facing the outer wall of the PPH pipeline 100, and the arc-shaped clamping surface is in close contact with the outer wall of the PPH pipeline 100. Figure 1 As shown in FIG. 1, the PPH pipeline locking tool comprises a rack 1 and a supporting member 2, the supporting member 2 is fixedly connected to the rack 1, and the supporting member 2 has an arc-shaped clamping surface, the arc-shaped clamping surface is formed on the side surface of the supporting member 2 facing the outer wall of the PPH pipeline 100, and the arc-shaped clamping surface is in close contact with the outer wall of the PPH pipeline 100.
[0038] In some embodiments, the PPH pipeline locking tool further comprises a locking member 4, the locking member 4 is fixedly connected to the supporting member 2 and can adjust the distance between the first hoop portion 22 and the second hoop portion 23 to adjust the size of the clamping space, so that the first hoop portion 22 and the second hoop portion 23 can clamp the PPH pipeline 100, thereby preventing rotation in the axial direction when the pressure device 3 applies pressure to the end surface of the pipeline joint 200, thereby ensuring the perpendicularity of the PPH pipeline 100 and the pipeline joint 200. Specifically, the first hoop portion 22 has a second fixed hole, the second hoop portion 23 has a second connecting hole, the locking member 4 is a bolt, the bolt passes through the second connecting hole and is connected with the second fixed hole, so that the bolt can be screwed to make the first hoop portion 22 and the second hoop portion 23 locally deform and approach each other, thereby adjusting the size of the clamping space to clamp the PPH pipeline 100.
[0039] Figure 2This diagram shows a cross-sectional view of the PPH pipe locking fixture provided in this embodiment. When the pressure device 3 applies pressure to the end face of the pipe connector 200, if the support member 2 is placed directly on the frame 1, uneven force on the end face of the pipe connector 200 may cause the support member 2 to tip over, resulting in the PPH pipe 100 and the pipe connector 200 failing to properly connect and lock. To solve the above technical problem, such as... Figures 1 to 2 As shown, the support member 2 also has a first connecting hole 24, and the frame 1 has a first fixing hole 11 corresponding to the first connecting hole 24. A locking element passes through the first connecting hole 24 and engages with the first fixing hole 11 to fix the support member 2 to the frame 1. This ensures that even when the end face of the pipe connector 200 is subjected to uneven force, the PPH pipe 100 and the pipe connector 200 can still be locked normally. Specifically, the locking element is a bolt, which passes through the first connecting hole 24 and engages with the first fixing hole 11 to fix the support member 2 to the frame 1.
[0040] Continue as Figures 1 to 2 As shown, the pressure device 3 includes a driver 31 and a pressure plate 32. The output end of the driver 31 is fixedly connected to the pressure plate 32. The pressure plate 32 faces the end face of the pipe connector 200. The driver 31 can drive the pressure plate 32 to move and press against the end face of the pipe connector 200, thereby applying pressure to the end face of the pipe connector 200 to achieve locking between the PPH pipe 100 and the pipe connector 200. Specifically, the driver 31 can be a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder, which is not limited here, as long as it can drive the pressure plate 32 to move linearly and press against the end face of the pipe connector 200.
[0041] In some embodiments, the driver 31 includes a mounting bracket 311, a pressing member 312, and an operating member 313. The mounting bracket 311 is fixedly connected to the frame 1, the pressing member 312 is slidably connected to the mounting bracket 311, one end of the pressing member 312 is fixedly connected to the pressure plate 32, and the operating member 313 is fixedly connected to the pressing member 312. The operating member 313 is used to drive the pressing member 312 to move the pressure plate 32 and press against the end face of the pipe connector 200, so that the operator can manually lock the PPH pipe 100 and the pipe connector 200, simplifying the structure of the PPH pipe 100 locking fixture. Specifically, the operating member 313 is a first connecting rod, and the pressing members 312 are all sliders. A rocker-slider mechanism is formed between the first connecting rod and the sliders, so that the first connecting rod can be rotated to move the sliders and drive the pressure plate 32 to move to press against the end face of the pipe connector 200.
[0042] In actual use of the PPH pipe 100, the PPH pipe 100 can be connected with another PPH pipe 100 as a main pipe by fusion, and the end of the PPH pipe 100 needs to be cut into a connecting pipe end 101 in the form of a line of intersection, so that the PPH pipe 100 can be connected with another PPH pipe 100 by fusion with less PPH material, thereby reducing the fusion time of the main pipe and the branch pipe and improving the fusion effect. When the PPH pipe 100 is connected with the pipe joint 200 at one end and is fused with another PPH pipe 100 at the other end, if the abutting portion 25 abuts against the connecting pipe end 101 when the PPH pipe 100 is connected with the pipe joint 200, the connecting pipe end 101 is easily damaged by external force, and more PPH material needs to be fused to realize the fusion of the main pipe and the branch pipe. To solve the above technical problems, the abutting portion 25 is provided with a profiling surface 251 matched with the outer contour of the connecting pipe end 101, and when the pressure device 3 applies pressure to the end face of the pipe joint 200, the connecting pipe end 101 abuts against the profiling surface 251, so that the pressure borne by the connecting pipe end 101 is uniformly distributed to the profiling surface 251, and the deformation of the connecting pipe end 101 is prevented. Figures 1 to 2
[0043] The embodiment also provides a PPH pipe locking method based on the PPH pipe locking tool.
[0044] The PPH pipe 100 is inserted into the pipe joint 200, the outer wall of the pipe joint 200 is placed in the clamping space of the support 2, the support 2 clamps the pipe joint 200, the fusion device heats the PPH pipe 100 and the pipe joint 200, the support 2 is placed on the rack 1, and the pressure device 3 applies pressure to the end face of the pipe joint 200 to realize the butt locking of the PPH pipe 100 and the pipe joint 200.
