[0002] Pipelines, especially gas pipelines, serve as the primary mode of transporting fluid fuels such as natural gas, forming a vast global transportation network and playing a vital role in the petrochemical industry and economic development. With the increasing number of gas pipelines and their extended operating time, the safe operation and accident prediction of these pipelines have garnered growing attention. In modern industrial production, the efficient operation of machinery is crucial for production efficiency and product quality. When machinery malfunctions or requires regular maintenance, precise alignment during the repair process is a key factor in ensuring the equipment's normal operation after repair.

[0003] Because existing maintenance alignment methods mostly rely on manual measurement and adjustment, they are not only inefficient but also require a high level of experience and skill from the operators, making it difficult to guarantee alignment accuracy. This can easily lead to poor equipment stability and increased failure rate after maintenance, thus failing to meet user needs. Utility Model Content

[0021] Please see Figure 1-3 ,

[0022] Example 1: A linear sliding table type mobile maintenance centering platform, including a platform base 2, universal wheels 1 evenly installed around the bottom of the platform base 2, and a tool storage compartment 3 provided at the top of the platform base 2.

[0023] A mounting platform 5 is provided on the top of the platform base 2. The mounting platform 5 is connected to the platform base 2 through a set of lifting cylinder group 4. The cylinders on the lifting cylinder group 4 are equipped with lifting handles 7. Two slide rails 6 are symmetrically arranged on both sides of the top of the mounting platform 5. Two fitter platforms 8 are symmetrically arranged on the top of the mounting platform 5. Two sliders 20 are symmetrically arranged on both sides of the bottom of the fitter platform 8. The sliders 20 are slidably locked on the slide rails 6. A front support frame 9 is provided on the top of the fitter platform 8.

[0024] A front support frame clamp 10 is provided on the top of the front support frame 9 of the equipment. Equipment 11 is provided on the top side of the fitter's platform 8. Equipment 11 is abutted by the front support frame 9 and the front support frame clamp 10 on both sides respectively. A push rod 12 is provided on the side of the mounting platform 5. Equipment 2 14 is provided on the side of Equipment 11. Equipment 2 15 is provided on the bottom side of Equipment 2 14. The bottom end of Equipment 2 15 is fixedly connected to the fitter's platform 8 through the provided equipment rear support frame 16. A ball screw assembly 18 is provided on the top of the mounting platform 5. A bench vise 19 is provided on the top of the fitter's platform 8. A directional wheel 21 is provided in the middle of the front end of the platform base 2.

[0025] The equipment 11 is fastened to the front support frame 9 and the front support frame clamp 10 by bolts.

[0026] The push rod 12 is equipped with a release handle 13, which is connected to the cylinder on the lifting cylinder group 4 via a connecting line.

[0027] Example 2: The difference between this example and Example 1 is that the rear support frame 16 of the equipment is fixedly connected to the fitter's platform 8 by bolts.

[0028] This makes it easier to assemble and disassemble the equipment rear support frame 16 and the fitter's platform 8.

[0029] Example 3: The difference between this example and Example 1 is that the ball screw assembly 18 includes connecting plates symmetrically fixed on both sides of the top center of the mounting platform 5. A bidirectional screw is rotatably connected between the two connecting plates. Two threaded sleeves are symmetrically sleeved on the bidirectional screw. The top of the threaded sleeves is fixed to the bottom of the fitter's platform 8. A handwheel 17 is connected to the end of the bidirectional screw.

[0030] This enables the ball screw assembly 18 to drive the two fitter platforms 8 to move closer to each other.

[0031] Example 4: The difference between this example and Example 1 is that the directional wheel 21 is rotatably connected to the platform base 2 through a fixed frame.

[0032] This makes it easier for the directional wheel 21 to rotate.

[0033] In this embodiment, since the existing maintenance alignment methods mostly rely on manual measurement and manual adjustment, not only is the operation inefficient, but also the operation requires a high level of experience and skill from the operators, making it difficult to guarantee alignment accuracy. This can easily lead to poor equipment operation stability and increased failure rate after maintenance, thus failing to meet the user's needs.

[0034] In summary, during actual implementation, when the user needs to align Equipment 11 and Equipment 2 14 during mobile maintenance, the user places the ends of Equipment 11 and Equipment 2 14 on the front support frame 9, and then tightens them with bolts through the front support frame clamp 10 and the front support frame 9, thereby stably fixing Equipment 11 and Equipment 2 14 on the fitter's platform 8. The ends of Equipment 11 and Equipment 2 14 are then abutted by the rear adjustment frame 15 and the rear support frame 16, so that Equipment 11 and Equipment 2 14 can be tightened and placed on the same horizontal plane.

[0035] Next, the user rotates the bidirectional screw in the ball screw assembly 18 via the handwheel 17, thereby driving the two fitter platforms 8 to move closer to each other and complete the centering operation of equipment 11 and equipment 2 14. The two sides of the bottom of the fitter platform 8 are slidably locked onto the slide rail 6 by the sliders 20, making the movement of the fitter platform 8 more stable.

[0036] As for the operation of the cylinders in the lifting cylinder assembly 4, the user can operate the cylinders through the lifting crank 7 and the release handle 13. The control connection between the cylinders and the release handle 13 and the lifting crank 7 is based on the principle of "mechanical pump oil + hydraulic drive + valve pressure relief". The lifting action is achieved through the linkage of the oil circuit and the mechanical structure. The core is that the hydraulic pump is driven by the crank to supply oil to the cylinder, and the pressure is released by controlling the opening and closing of the oil circuit through the release handle 13. The two work together to realize the reciprocating motion of the cylinder, thereby realizing the height adjustment of the installation platform 5 by the lifting cylinder assembly 4. In actual use, the device can drive the installation platform 5 to be raised and lowered to the optimal ergonomic operating height through the lifting cylinder assembly 4, which can meet the operation of people of different heights and avoid muscle injury.

[0037] Meanwhile, the device can be installed on different platforms according to different equipment types, such as monitoring pressure regulating valves, ball valves, and regulating valves. The platform is equipped with a fixing slot, which can install and fix various clamps, such as V-clamps, fitter's benches, core pulling devices, etc., to achieve the functions of fixing, bearing load, and safely disassembling and assembling different models of flow meters and valves. Moreover, once the equipment is fixed, it can be directly closed after separate maintenance, and quick centering is achieved without the need for further adjustment, saving a lot of centering time and ensuring installation accuracy.
