[0028] Please refer to Figures 1-4, the present utility model provides a technical solution:

[0029] A convenient jacking device for pressure pipelines, including a moving box 1. A hydraulic cylinder 2 is installed on the lower wall inside the moving box 1. An adjusting mechanism 3 is installed at the output end of the hydraulic cylinder 2. The upper end of the adjusting mechanism 3 is fixedly connected to a connecting seat 4. The upper end of the connecting seat 4 is fixedly connected to a limiting cylinder 5. A supporting pad 6 is fixedly connected to the lower wall inside the limiting cylinder 5. Limiting mechanisms 7 are installed on the upper left side and upper right side of the outer surface of the limiting cylinder 5. A control panel 8 is arranged at the front end of the moving box 1. A push handle 9 is fixedly connected to the right end of the moving box 1. Universal wheels 10 are installed at the four corners of the lower end of the moving box 1.

[0030] In this embodiment, the adjusting mechanism 3 includes an adjusting seat 31. An adjusting groove 32 is opened at the upper end of the adjusting seat 31. An activity groove 33 is opened at the upper part of the inner wall of the adjusting groove 32. A motor 34 is installed at the left part of the lower groove wall of the adjusting groove 32. The output end of the motor 34 is installed with a rotating rod 35. The upper end of the rotating rod 35 is fixedly connected to a driving gear 36. The right part of the outer surface of the driving gear 36 is meshed and connected with a driven gear 37. The upper end of the driven gear 37 is fixedly connected to an adjusting disc 38 through a rotating column. An activity ring 39 is fixedly connected to the outer surface of the adjusting disc 38. The lower end of the adjusting seat 31 is fixedly connected to the hydraulic cylinder 2. The lower end of the driven gear 37 is movably connected to the lower groove wall of the adjusting groove 32 through a rotating column and a bearing. The upper end of the adjusting disc 38 is fixedly connected to the connecting seat 4, and the outer surface of the adjusting disc 38 does not contact the inner wall of the adjusting groove 32. The activity ring 39 is movably connected to the activity groove 33.

[0031] Through the above solution: Start the motor 34. The motor 34 drives the rotating rod 35 to rotate. The rotating rod 35 drives the driving gear 36 to rotate. The driving gear 36 drives the driven gear 37 to rotate. The driven gear 37 drives the adjusting disc 38 to rotate through a rotating column. The adjusting disc 38 drives the limiting cylinder 5 to rotate through the connecting seat 4, so that the pressure pipeline in the limiting cylinder 5 can be conveniently adjusted in angle for jacking and docking installation, and the accurate connection between pressure pipelines can be realized more quickly, reducing the installation time and labor cost. Moreover, through precise angle adjustment, it helps to better ensure the sealing effect at the pipeline connection and reduce the leakage risk.

[0032] In this embodiment, the limiting mechanism 7 includes a cylinder 71. A limiting plate 72 is installed at the output end of the cylinder 71. A limiting pad 73 is fixedly connected to the lower wall inside the limiting plate 72. The cylinder 71 is installed on the upper part of the outer surface of the limiting cylinder 5, and the limiting plate 72 is located inside the limiting cylinder 5.

[0033] Through the above solution: Place the pressure pipeline to be butt - joint installed inside the limiting cylinder 5, support the lower part of the pressure pipeline through the supporting pad 6, start two cylinders 71, and the two cylinders 71 respectively push the two limiting plates 72 to move downward, so that the two limiting pads 73 are closely attached to the upper part of the pressure pipeline. The pressure pipeline can be limited inside the limiting cylinder 5 through the two limiting plates 72, which is convenient for the butt - joint installation of the pressure pipeline, can improve the stability of the pressure pipeline during butt - joint installation, and can be applied to the butt - joint installation of pressure pipelines with different diameters.

[0034] It should be noted that the present utility model is a convenient jacking device for pressure pipelines. During use, when it is necessary to butt - joint and install a pressure pipeline, first place the pressure pipeline inside the limiting cylinder 5, use the supporting pad 6 to support the lower part of the pipeline. Subsequently, by starting two cylinders 71, the two cylinders 71 will push the corresponding limiting plates 72 to move downward until the two limiting pads 73 are closely attached to the upper part of the pressure pipeline. In this way, the two limiting plates 72 work together to firmly limit the pressure pipeline inside the limiting cylinder 5, ensuring the stability during the butt - joint installation of the pressure pipeline, and being able to adapt to pressure pipelines with different diameters for jacking and butt - joint installation. Once the pipeline is firmly limited, the hydraulic cylinder 2 will be started to jack the pipeline to the required position. At the same time, the motor 34 starts to work, driving the rotating rod 35 to rotate. The rotation of the rotating rod 35 will drive the driving gear 36 to rotate, and then through the meshing between gears, the driven gear 37 will also start to rotate. The driven gear 37 drives the adjusting disc 38 to rotate further through the rotating column connected to it. The rotation of the adjusting disc 38 will drive the limiting cylinder 5 connected to it to rotate, thereby realizing the angle adjustment of the pressure pipeline. This not only improves the efficiency and accuracy of the butt - joint installation of the pressure pipeline, reduces the time and labor costs required for installation, but also through precise angle adjustment, helps to ensure the sealing effect at the pipeline connection, reducing the risk of leakage. The entire convenient jacking device for pressure pipelines is simple to operate, safe and reliable, providing great convenience for the butt - joint installation of pressure pipelines.
