Description

Technical Field

[0001] This invention relates to the field of pipeline inspection technology, and in particular to an inspection and testing device for pressure pipelines in municipal engineering. Background Technology

[0002] Pressure pipelines in municipal engineering projects bear multiple loads over long periods, including medium pressure, soil load, and temperature deformation. If the pipeline itself, welds, or joints have strength defects, leaks and pipe bursts are highly likely, threatening the safe operation of the urban pipe network and the safety of people and property. Before use, pressure pipelines in municipal engineering projects must undergo pressure testing to verify whether their overall pressure-bearing capacity meets design requirements.

[0003] Currently, pipeline inspections mostly employ traditional pressure testing fixtures and simple testing equipment, which are cumbersome to operate and inconvenient for multi-directional and multi-position pressure strength testing of pressure pipelines. The pipeline position can only be adjusted with the help of other tools, which is also inconvenient to operate and can easily lead to problems such as long inspection time. In addition, the existing testing fixtures are not highly adaptable to pipeline inspection. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a testing and inspection device for municipal engineering pressure pipelines.

A second worm is disposed inside the second mounting cavity, and both of the two second worm gears mesh with the second worm. Both ends of the second worm are rotatably connected to the inner wall of the second mounting cavity. A first motor is fixedly mounted on the outer wall of the base, and the output shaft of the first motor passes through the base and is fixedly connected to the end of the second worm.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Reference Figures 1-4A municipal engineering pressure pipeline inspection and testing device includes a base 1, a movable frame 3 on top of the base 1, and first movable grooves 4 on opposite side walls of the movable frame 3. Each of the two first movable grooves 4 contains a first movable block 6, through which a first one-way threaded rod 5 threadedly connects to the first movable block 6. Both ends of the first one-way threaded rod 5 are rotatably connected to the inner wall of the first movable groove 4. The movable frame 3 contains a first mounting cavity 19, inside which is a first driving mechanism connected to the first one-way threaded rod 5. A compression testing mechanism is located on the side wall of the first movable block 6. Two second movable grooves 27 are located at the upper end of the base 1, and both ends of the movable frame 3 slide on the two grooves respectively. Inside each of the two second moving slots 27, there is a second one-way threaded rod 29. The second one-way threaded rod 29 passes through the moving frame 3 and is threadedly connected to the moving frame 3. Both ends of the second one-way threaded rod 29 are rotatably connected to the inner wall of the second moving slot 27. Inside the base 1, there is a second mounting cavity 30. Inside the second mounting cavity 30, there is a second driving mechanism connected to the second one-way threaded rod 29. Above the base 1, there is a pipe body 15. At the upper end of the base 1, there are two fixing mechanisms for fixing the pipe body 15. At the upper end of the base 1, there is a movable slot 28. The movable slot 28 is located between the two second moving slots 27. Inside the movable slot 28, there is an adjustment mechanism connected to the fixing mechanism.

[0023] In this invention, the first driving mechanism includes two first connecting shafts 21 disposed inside the first mounting cavity 19. One end of each first connecting shaft 21 is rotatably connected to the inner wall of the first mounting cavity 19, and the other end of each first connecting shaft 21 penetrates the inner wall of the first mounting cavity 19 and is fixedly connected to two first one-way threaded rods 5 respectively. A first worm gear 22 is fixedly sleeved on each of the two first connecting shafts 21. A first worm 20 is disposed inside the first mounting cavity 19, and both ends of the first worm 20 are rotatably connected to the inner wall of the first mounting cavity 19. Each of the first worm gears 22 meshes with the first worm 20. A second motor 23 is installed on the outer wall of the movable frame 3. The output shaft of the second motor 23 passes through the movable frame 3 and is fixedly connected to the end of the first worm 20. When the second motor 23 is started, the first worm 20 is driven to rotate, which in turn drives the two first one-way threaded rods 5 to rotate synchronously, which in turn drives the first moving block 6 to move vertically. This allows for flexible adjustment of the vertical position of the extrusion detection mechanism. When the pipe body 15 has different thicknesses, the vertical position of the extrusion detection mechanism can be adjusted to adapt to the different thicknesses.

[0024] The extrusion detection mechanism includes a first hydraulic cylinder 7 fixedly installed on the side wall of the first movable block 6. An extrusion rod 8 is fixedly connected to the telescopic end of the first hydraulic cylinder 7. A detection clamping block 9 is provided on one side of the extrusion rod 8. An arc-shaped clamping groove is provided on the side wall of the detection clamping block 9. An extrusion groove 10 is provided on the side wall of the detection clamping block 9. The extrusion rod 8 is slidably inserted into the inside of the extrusion groove 10. A pressure sensor 11 is installed between the inner wall of the extrusion groove 10 and the extrusion rod 8. A laser rangefinder sensor 37 is provided at the upper end of the detection clamping block 9. By activating the extension of the first hydraulic cylinder 7, the detection clamping block 9 is driven to extrude the side wall of the pipe body 15, which can extrude the side wall of the pipe body 15. The pressure sensor 11 can monitor the pressure being detected, and the laser rangefinder sensor 37 can monitor the deformation of the pipe body 15, thereby enabling efficient and rapid detection of the pipe body 15.

[0025] The second drive mechanism includes two second connecting shafts 33 disposed inside the second mounting cavity 30. One end of each second connecting shaft 33 is rotatably connected to the inner wall of the second mounting cavity 30, and the other end of each second connecting shaft 33 passes through the inner wall of the second mounting cavity 30 and is fixedly connected to the second one-way threaded rod 29. A second worm gear 32 is fixedly sleeved on each of the two second connecting shafts 33. A second worm 31 is disposed inside the second mounting cavity 30, and both second worm gears 32 mesh with the second worm 31. Both ends of the second worm 31 are rotatably connected to the inner wall of the second mounting cavity 30. A first motor 2 is fixedly mounted on the outer wall of the base 1. The output shaft of the first motor 2 passes through the base 1 and is fixedly connected to the end of the second worm 31. When the first motor 2 is started, the second worm 31 is driven to rotate, which in turn drives the two second one-way threaded rods 29 to rotate synchronously, which in turn drives the moving frame 3 to move, thereby adjusting the lateral position of the extrusion detection mechanism and enabling detection of different lateral positions of the pipe body 15.

[0026] The fixing mechanism includes a movable base 12, with a mounting frame 16 fixedly connected to the upper end of the movable base 12. A third hydraulic cylinder 18 is fixedly mounted on the upper end of the mounting frame 16. The telescopic end of the third hydraulic cylinder 18 passes downward through the mounting frame 16 and is fixedly connected to a pressure plate 17. The upper end of the movable base 12 is provided with a mounting groove 13. When the third hydraulic cylinder 18 is activated, it extends, causing the pressure plate 17 to move downward and press and fix the pipe body 15, thereby supporting and fixing both ends of the pipe body 15, thus ensuring the stability of the pipe body 15 during the inspection process. The mounting groove 13 is provided with a rotating structure inside, which includes a second hydraulic cylinder 14 fixedly mounted on the bottom wall of the mounting groove 13. The extension end of the second hydraulic cylinder 14 faces upward and is fixedly connected to a device box 34. Two rollers 36 are rotatably mounted inside the device box 34. A fourth motor 35 is mounted on the outer wall of the device box 34. The output shaft of the fourth motor 35 passes through the device box 34 and is fixedly connected to the end of one of the rollers 36. When it is necessary to rotate the pipe body 15, the second hydraulic cylinder 14 is activated to extend, which drives the device box 34 to move upward. The pipe body 15 is lifted by the rollers 36. Then the fourth motor 35 is activated to drive the rollers 36 to rotate. The rollers 36 can drive the pipe body 15 to rotate.

[0027] The adjustment mechanism includes a bidirectional threaded rod 25 disposed inside the movable groove 28. Both ends of the bidirectional threaded rod 25 are rotatably connected to the inner wall of the movable groove 28. Two second moving blocks 26 are threadedly sleeved on the bidirectional threaded rod 25. The second moving blocks 26 are fixedly connected to the lower end of the movable base 12. A third motor 24 is fixedly installed on the side wall of the base 1. The output shaft of the third motor 24 passes through the base 1 and is fixedly connected to the end of the bidirectional threaded rod 25. When the third motor 24 is started, the bidirectional threaded rod 25 is driven to rotate. Since the two second moving blocks 26 are threadedly connected to the bidirectional threaded rod 25, the two second moving blocks 26 can move synchronously, thereby adjusting the position of the fixing mechanism. This allows the fixing mechanism to adapt to fixing pipe bodies 15 of different lengths, making it highly adaptable.
