[0029] Static pressure testing system 300. Detailed Implementation

[0030] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0031] Please see Figures 1 to 5 As shown, this utility model provides a static pressure detection system 300. The static pressure detection system 300 includes a high-pressure pipe 200 and a lifting and adjusting device 100.

[0032] The high-pressure pipe 200 is cylindrical and relatively heavy. The lifting and adjusting device 100 includes a desktop assembly 10, two support fixture assemblies 20 mounted on a desktop 12, and a fixing assembly 30 mounted on the desktop 12 and located between the two support fixture assemblies. The support fixture assembly 20 has a support groove 22 for clamping and fixing the high-pressure pipe 200 and a lifting platform 21 for driving the support groove 22 to move up and down relative to the desktop 12. The fixing assembly 30 has a clamping device 31 for clamping the high-pressure pipe 200 and a first connecting rod 32 that allows the clamping device 31 to move up and down relative to the desktop 12. By setting up the support fixture assembly 20 and the fixing assembly 30, the high-pressure pipe 200 is placed in the support groove 22 of the support fixture assembly 20 and the clamping device 31 of the fixing assembly 30. The lifting platform 21 drives the support groove 22 to move up and down relative to the desktop 12, eliminating the need for manual handling and adjustment of the high-pressure test pipe, thus facilitating the adjustment of the height and position of the high-pressure pipe 200. When rapid water injection and drainage are required, simply raising one of the support fixture components 20 to tilt the high-pressure pipe 200 enables rapid water injection and drainage. Furthermore, the support groove 22 and clamping device 31 prevent the high-pressure pipe 200 from sliding or rolling during movement, ensuring convenient operation and high safety.

[0033] Please see Figure 3 and combined Figures 1 to 2 As shown, the desktop component 10 includes a table base 11, a tabletop 12, and a plurality of table legs 13 disposed between the table base 11 and the tabletop 12.

[0034] In this example, the table base 11, tabletop 12, and table legs 13 are all rigid components. Furthermore, the table base 11 and tabletop 12 have rectangular structures, and most of the lifting and adjusting device 100 is located on the tabletop 12. In other embodiments, the table base 11 and tabletop 12 can also be other shapes, such as squares.

[0035] In this embodiment, seven table legs 13 are provided between the table base 11 and the tabletop 12. All seven table legs 13 are cylindrical, including four table legs 13 located at the four corners between the table base 11 and the tabletop 12, and three table legs 13 located in the middle. Optionally, all seven table legs 13 are welded between the table base 11 and the tabletop 12. In other embodiments, the number and shape of the table legs 13 can be designed as needed, and this utility model does not limit this.

[0036] Furthermore, the multiple table legs 13 are hollow, with a hollow section for accommodating the first connecting rod 32 of the fixing component 30 and the second connecting rod 23 of the support tooling component 20. This allows the clamping device 31 in the fixing component 30 and the support groove 22 in the support tooling component 20 to move up and down within the hollow section of the table legs 13, thereby achieving height adjustment while improving aesthetics.

[0037] Furthermore, to improve the sturdiness of the table legs 13, a reinforcing member 15 is welded between the table legs 13 and the table base 11. For example, it can be four reinforcing ribs.

[0038] Preferably, when welding the table legs 13 to the tabletop 12 and table base 11, it should be ensured that the tabletop 12 and table base 11 are parallel and aligned after welding. The overall top and bottom views of the welded tabletop assembly 10 should show that the tabletop 12 and table base 11 have identical shapes. There are also reinforcing members 15 between the table legs 13 and the table base 11. For example, each table leg 13 at the four corners can have four reinforcing members 15 welded to the table base 11.

[0039] Furthermore, the desktop 12 is provided with multiple mounting holes to facilitate the installation of the support fixture assembly 20 on the desktop 12. Other components include the fixing assembly 30, drive motor 25, coupling 27, etc.

[0040] Furthermore, the desktop assembly 10 also includes casters 14 disposed on the side of the table base 11 opposite to the desktop 12. By providing casters 14, the lifting and adjusting device 100 can be moved easily, thereby facilitating the transport of the high-pressure pipe 200 and improving operational convenience.

[0041] In this embodiment, four casters 14 are provided at the four corners of the table base 11. The four casters 14 are connected to the table base 11 by bolts and nuts. In other embodiments, the number of casters 14 can be appropriately increased or decreased as needed.

[0042] Optionally, the relative distance between the holes of each caster wheel 14 and the table base 11 should be consistent to ensure that each caster wheel 14 can be installed on the table base 11. After installation, the table base 11 and casters 14 should be positioned horizontally when placed on a flat surface to improve the stability and smoothness of sliding.

[0043] Please see Figure 4 and combined Figures 1 to 3 As shown, the lifting and adjusting device 100 includes two supporting fixture assemblies 20. The two supporting fixture assemblies 20 are respectively disposed at opposite ends of the tabletop 12. Each supporting fixture assembly 20 includes a lifting platform 21 and a supporting groove 22 disposed above the lifting platform 21. The supporting groove 22 is used to clamp and fix the high-pressure pipe 200. The lifting platform 21 is configured to be driven to move the supporting groove 22 up and down relative to the tabletop 12. Thus, by moving the supporting groove 22 up and down relative to the tabletop 12 through the lifting platform 21, the high-pressure test pipe is not manually handled or adjusted, thereby facilitating the adjustment of the height and position of the high-pressure pipe 200.

[0044] The lifting platform 21 includes a base 211, a support block 212, and a transmission assembly 213. The base 211 is fixedly mounted on the tabletop 12. For example, the base 211 can be fixed to the tabletop 12 using fasteners such as bolts and nuts. The support block 212 is movably mounted within the base 211 and is connected to the transmission assembly 213. The transmission assembly 213 drives the support block 212 to move up and down, which in turn drives the support groove 22 to move up and down.

[0045] Specifically, the transmission assembly 213 includes a first transmission member and a second transmission member disposed below the support block 212. For example, the first transmission member may be a worm gear, and the second transmission member may be a worm. One end of the worm is connected to the bottom surface of the support block 212, and the other end passes through the tabletop 12 and is at least partially located between the tabletop 12 and the table bottom 11.

[0046] One end of the support block 212 is fixedly connected to the bottom surface of the support groove 22. For example, it can be fixedly connected by fasteners such as bolts and nuts. The other end of the support block 212 is connected to the worm gear.

[0047] Furthermore, the lifting platform 21 is equipped with rotating wheels 26, which are connected to the first transmission component in the transmission assembly 213. These wheels are configured to manually drive the support block 212 to move up and down relative to the tabletop 12, thereby causing the support groove 22 to move up and down relative to the tabletop 12. Optionally, the line connecting the centers of the two rotating wheels 26 is precisely located on the center line of the tabletop 12 to improve the stability of the lifting operation.

[0048] Optionally, the lifting adjustment device 100 also includes a drive motor 25 and a coupling 27. The drive motor 25 is mounted on the tabletop 12 and is connected to the transmission assembly 213 via the coupling 27. It is configured such that the drive motor 25 drives the coupling 27 to rotate, and the coupling 27 drives the support block 212 to move up and down relative to the tabletop 12, thereby causing the support groove 22 to move up and down relative to the tabletop 12. The drive motor 25 can be fixed to the tabletop 12 by bolts or similar connections. The positional relationship between the drive motor 25 and the lifting platform 21 after installation should be coaxial to ensure that the drive motor 25 can normally drive the support groove 22 on the lifting platform 21 to rise and fall.

[0049] In this embodiment, a drive motor 25 and a coupling 27 are provided to drive one of the lifting platforms 21 to move, thereby causing a support groove 22 to move up and down relative to the tabletop 12. This allows one end of the high-pressure pipe 200 to be raised or lowered, making the use of the lifting platform 21 for the high-pressure pipe 200 more labor-saving. In other embodiments, two drive motors 25 and two couplings 27 can be provided, with each drive motor 25 connected to one of the lifting platforms 21 via a coupling 27.

[0050] Furthermore, one end of the coupling 27 can be connected to the motor shaft of the drive motor 25, and the other end can be fixedly connected to the rotating wheel 26.

[0051] Optionally, the line connecting the centers of the two lifting platforms 21 is parallel to the longest side of the tabletop 12. This arrangement ensures that, when the lifting adjustment device 100 is in use, the high-pressure pipe 200 is positioned precisely in the center of the entire lifting adjustment device 100, which helps maintain balance.

[0052] Furthermore, the support groove 22 includes two inclined groove sidewalls 221 and a groove bottom wall 222 disposed between the two groove sidewalls 221. The two groove sidewalls 221 are gradually tapering into a funnel shape from the end away from the groove bottom wall 222 to the end near the groove bottom wall 222. This arrangement facilitates the placement of the high-pressure pipe 200. At the same time, the gradually narrowing groove inner wall facilitates clamping the high-pressure pipe 200 and prevents the high-pressure pipe 200 from sliding during movement.

[0053] Furthermore, each of the two sidewalls 221 of the support groove 22 is provided with a universal ball 223. The support groove 22 is connected to the high-pressure pipe 200 through the universal ball 223. This arrangement improves the stability of the connection and prevents damage to the high-pressure pipe 200.

[0054] A second connecting rod 23 is provided below the support groove 22, and the support groove 22 is movably connected to the table leg 13 through the second connecting rod 23. Optionally, the second connecting rod 23 is a solid round steel. The table leg 13 has a hollow part, and the tabletop 12 has a through hole corresponding to the position of the second connecting rod 23. The second connecting rod 23 passes through the through hole and is sleeved in the table leg 13, and is movably connected to the table leg 13.

[0055] To improve the stability of the support fixture assembly 20, the support fixture assembly 20 also includes a support member 24. One end of the support member 24 is connected to the bottom wall 222 of the support groove 22, and the other end is connected to the tabletop 12. Furthermore, the support member 24 is positioned corresponding to the table leg 13, and the second connecting rod 23 passes through the support member 24 and is fitted into the hollow part of the table leg 13. That is, the table leg 13 and the second connecting rod 23 are concentrically arranged to ensure smooth vertical movement.

[0056] Please see Figure 5 and combined Figures 1 to 4 As shown, the fixing component 30 is set on the desktop 12 and located between the two support fixture components 20, for fixing the middle part of the high-pressure pipe 200.

[0057] The fixing assembly 30 includes a clamping device 31, a rotating shaft 33, and a first connecting rod 32 disposed below the clamping device 31. The clamping device 31 is connected to the first connecting rod 32 via the rotating shaft 33, and can rotate relative to the rotating shaft 33 as the rotation center. For example, it can deflect left or right as shown in the figure. This arrangement allows the clamping device 31 to deflect at a certain angle when one end of the high-pressure pipe 200 is lifted, thereby enabling the clamping device 31 to clamp the high-pressure pipe 200 more stably, preventing the high-pressure pipe 200 from slipping during lifting or lowering, and improving operational safety.

[0058] The clamping device 31 includes an upper clamping device 311 and a lower clamping device 312 that are detachably connected. A passage 313 is provided between the upper clamping device 311 and the lower clamping device 312 for the high-pressure pipe 200 to pass through. This arrangement facilitates the installation and removal of the high-pressure pipe 200.

[0059] The first connecting rod 32 is movably connected to the table leg 13. Optionally, the first connecting rod 32 is a solid round steel. The table leg 13 has a hollow part, and the tabletop 12 has a through hole corresponding to the position of the first connecting rod 32. The first connecting rod 32 passes through the through hole and is sleeved inside the table leg 13, and is movably connected to the table leg 13.

[0060] When a hydrostatic pressure test is required, the high-pressure pipe 200 is moved using the lifting and adjusting device 100, which is convenient, time-saving, and labor-saving. When water needs to be added, one of the drive motors 25 or one of the rotating wheels 26 rotates, causing one of the lifting platforms 21 to move one end of the high-pressure pipe 200 upwards via the support groove 22 until it is full. During the pressurization process, the two lifting platforms 21 are adjusted to keep the high-pressure pipe 200 in a horizontal position. After the test is completed, all the water in the high-pressure pipe 200 needs to be drained. The lifting platform 21 and the support groove 22 are then used to raise one end of the high-pressure pipe 200 to perform the drainage operation, which is convenient, quick, time-saving, labor-saving, and highly safe.

[0061] In summary, this utility model provides a lifting and adjusting device 100 and a pressure reduction detection system for adjusting a high-pressure pipe 200. By setting up a supporting fixture assembly 20 and a fixing assembly 30, the high-pressure pipe 200 is placed within the supporting groove 22 of the supporting fixture assembly 20 and the clamping device 31 of the fixing assembly 30. The lifting platform 21 drives the supporting groove 22 to move up and down relative to the tabletop 12, eliminating the need for manual handling and adjustment of the high-pressure test pipe, thus facilitating the adjustment of the height and position of the high-pressure pipe 200. When rapid water injection and drainage are required, simply raising one of the supporting fixture assemblies 20 to tilt the high-pressure pipe 200 enables rapid water injection and drainage. Furthermore, the supporting groove 22 and clamping device 31 prevent the high-pressure pipe 200 from sliding or rolling during movement, ensuring convenient operation and high safety.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
