Description

Technical Field

[0001] The present invention belongs to the technical field of pressure pipeline detection. Specifically, it particularly relates to a pressure detection device for the ports of special equipment pressure pipelines. Background Art

[0002] Pressure pipelines belong to special equipment and play an extremely important role in people's daily lives. The process requirements for pressure pipelines such as those for transporting crude oil, steam, and process raw materials in people's production and life are extremely high. To effectively avoid combustion and explosion phenomena during transportation; and the pressure detection device for the ports of special equipment pressure pipelines is a device specifically used to detect the pressure at the ports of special equipment pressure pipelines. It is mainly applied to scenarios where precise measurement and control of the pressure at the ports of pressure pipelines are required to ensure the safe operation of pressure pipelines.

[0003] Due to the special structure of the pressure pipeline itself, it is very difficult for ordinary detection equipment to detect the pressure pipeline. Generally, the detection equipment is connected to the pipeline port to complete the detection work inside the pipeline. However, due to the different specifications of the pressure pipeline itself, there are various pressure pipelines with different apertures in the factory area. To ensure the sealing performance during the detection process, the aperture of ordinary detection equipment corresponds one by one to the aperture of the pressure pipeline, and it is very difficult for a set of detection devices to meet the detection needs of various pressure pipelines with different apertures.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

A plurality of sealing rings are coaxially arranged, and the diameters of the plurality of sealing rings gradually increase in the radially outward direction.

[0010] Further, the detection mechanism includes an air delivery pipe provided on the sealing ring.

[0015] The present invention has the following beneficial effects compared with the prior art:

[0016] 1. Through the moving column inside the support column and the worm and worm gear transmission mechanism in the present invention, the height adjustability of the fixing mechanism is realized. This means that the device can be secondarily adjusted according to pipes of different diameters and lengths, ensuring stable clamping and strong adaptability. This design greatly improves the versatility of the device, enabling the same set of equipment to meet the detection requirements of various specifications of pipes, reducing equipment costs and storage space requirements.

[0017] 2.

Detailed implementation manner

[0029] Next, the technical solutions in the embodiments of the invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments. Based on the embodiments of the invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the invention.

[0030] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present invention.

[0031] Please refer to Figures 1 - 6 As shown, the present invention is a special equipment pressure pipeline port pressure detection device, including a workbench 1. A moving block 2 is slidably connected above the workbench 1. A support column 3 is fixedly installed above the moving block 2. A moving column 4 is slidably connected inside the support column 3. A fixing mechanism is arranged above the moving column 4. The fixing mechanism includes a fixed disk 5 arranged above the moving column 4. A first gear 6 is rotatably installed inside the fixed disk 5. The first gear 6 meshes with a second gear 7. An annular thread 8 is fixedly installed above the second gear 7. The annular thread 8 meshes with the bottom of the clamping block 9. The clamping block 9 is slidably connected to the disk 10. The fixing mechanism is used for clamping the pipeline 11. Sealing rings 12 are arranged at both ends of the pipeline 11. One of the sealing rings 12 is provided with a detection mechanism.

[0032] The working principle of the special equipment pressure pipeline port pressure detection device proposed by the present invention is that by moving the moving block 2, the support column 3, the moving column 4 and the fixing mechanism are driven to move, so that the distance between the two fixing mechanisms can be adjusted according to the length of the pipeline 11. And by moving the moving column 4 inside the support column 3, the fixing mechanism is driven to rise or fall, so that secondary adjustment can be carried out according to the size of the pipeline 11.

[0033] When the pipe 11 needs to be fixed, first pass both ends of the pipe 11 through the disc 10 and the fixed disc 5. Then, the operator rotates the first gear 6, which drives the second gear 7 to rotate, and further drives the annular thread 8 to rotate, thereby driving the clamping block 9 to approach or move away from the center position of the disc 10, and thus different-diameter pipes 11 can be fixedly clamped.

[0034] After completing the above fixation of the pipe 11, seal both ends of the pipe 11 through the sealing ring 12, and then start the detection mechanism to detect the sealing performance of the pipe 11.

[0035] In one embodiment, for the above-mentioned workbench 1, a first chute 13 is provided above the workbench 1. A bidirectional threaded rod 14 is rotatably installed inside the first chute 13. Both ends of the bidirectional threaded rod 14 are threadedly connected with moving blocks 2. One end of the bidirectional threaded rod 14 is fixedly installed with the output shaft of a first motor 29, and the first motor 29 is fixedly installed on the workbench 1.

[0036] The working principle of the special equipment pressure pipeline port pressure detection device proposed by the present invention is that by starting the first motor 29, the bidirectional threaded rod 14 is driven to rotate, and then the two moving blocks 2 are driven to approach or move away from the central axis position of the first chute 13 at the same time, so as to drive the two fixing mechanisms to approach or move away from the central axis position of the first chute 13 at the same time, and thus the adjustment can be made according to the length of the pipe 11.

[0037] In one embodiment, for the above-mentioned support column 3, a first threaded rod 15 is rotatably installed inside the support column 3. The first threaded rod 15 is threadedly connected with a moving column 4. The first threaded rod 15 is fixedly installed with a worm gear 16, and the worm gear 16 is engaged with a worm 17. The worm 17 is rotatably installed on the support column 3.

[0038] The working principle of the special equipment pressure pipeline port pressure detection device proposed by the present invention is that by rotating the worm 17, the worm gear 16 is driven to rotate, and then the first threaded rod 15 is driven to rotate, so as to drive the moving column 4 to rise or fall along the inside of the support column 3, and further drive the fixing mechanism to rise or fall, and thus the secondary adjustment can be made according to the size of the pipe 11.

[0039] In one embodiment, for the above-mentioned fixed disc 5, the fixed disc 5 is fixedly installed on the moving column 4. There are two groups of clamping mechanisms, and their parts and installation methods are the same. A plurality of sealing rings 12 are coaxially arranged, and the diameters of the plurality of sealing rings 12 gradually increase in the radially outward direction.

[0040] The working principle of the pressure detection device for the ports of special equipment pressure pipelines proposed by the present invention is that by setting multiple groups of sealing rings 12, pipelines 11 with different diameters can be sealed, improving work efficiency.

[0041] In one embodiment, for the above-mentioned detection mechanism, the detection mechanism includes an air delivery pipe 18 arranged on the sealing ring 12. One end of the air delivery pipe 18 is fixedly communicated with the sealing ring 12, and the other end is fixedly communicated with an electric air pump 19. The electric air pump 19 is fixedly installed at the bottom of the workbench 1, and the electric air pump 19 is electrically connected to a pressure detector 20.

[0042] The working principle of the pressure detection device for the ports of special equipment pressure pipelines proposed by the present invention is that when the electric air pump 19 is started, the electric air pump 19 delivers air into the pipeline 11 through the air delivery pipe 18. At this time, observe the numerical change of the pressure detector 20. If the value of the pressure detector 20 becomes lower, it indicates that there is a leak in the pipeline 11, thereby judging whether the sealing performance of the pipeline is qualified.

[0043] In one embodiment, for the above-mentioned workbench 1, a second sliding groove 21 is opened above the workbench 1. A second threaded rod 22 is rotatably installed inside the second sliding groove 21. One end of the second threaded rod 22 is fixedly installed with a second motor 23, and the second motor 23 is fixedly installed on the workbench 1.

[0044] In one embodiment, for the above-mentioned second threaded rod 22, an electric base frame 24 is threadedly connected to the second threaded rod 22, and the electric base frame 24 is slidably connected inside the second sliding groove 21.

[0045] In one embodiment, for the above-mentioned electric base frame 24, a driving cylinder 25 is fixedly installed above the electric base frame 24. The output shaft of the driving cylinder 25 is fixedly installed with a pressing plate 26, and a pressure detector 27 is fixedly installed on the pressing plate 26.

[0046] In one embodiment, for the above-mentioned workbench 1, support legs 28 are fixedly installed at the bottom of the workbench 1, and there are four support legs 28.

[0047] The working principle of the pressure detection device for the ports of special equipment pressure pipelines proposed by the present invention is that by starting the second motor 23, the second threaded rod 22 is driven to rotate, thereby driving the electric base frame 24 to move. Subsequently, the driving cylinder 25 is started, driving the pressing plate 26 to move downward and pressing the pipeline 11, thereby completing the pressure detection of the pipeline 11. At this time, the pressure size received by the pipeline 11 can be observed in real time through the pressure detector 27.

[0048] The electric base frame 24 drives the driving cylinder 25 to move, thereby completing the pressure detection of different positions of the pipeline 11.
