Description

Technical Field

[0001] This utility model relates to the field of detection technology, specifically to an oil and gas pipeline failure analysis device. Background Technology

[0002] After welding and assembly, oil and gas pipelines need to undergo failure analysis to ensure the stability and reliability of the finished product.

[0003] Failure analysis of oil and gas pipelines requires airtightness testing and flaw detection.

[0004] The current operating mode involves separate testing, requiring the transfer of oil and gas pipelines to the airtightness testing station and the flaw detection station. Airtightness testing is performed using the corresponding gas source equipment, and flaw detection is performed using the corresponding detectors.

[0005] The process is time-consuming and has low testing efficiency; it requires many repeated clamping operations and is cumbersome. Utility Model Content

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, this utility model proposes an oil and gas pipeline failure analysis device, comprising:

[0008] Two sealing discs are used to seal the flanges of the oil and gas pipeline.

[0009] A delivery pipe is fixedly installed on one of the sealing discs, and the delivery pipe is connected to the sealing disc;

[0010] A support shaft, which is fixedly installed on another of the sealing discs;

[0011] The clamps are two in number, and the two clamps are respectively disposed on the two sealing discs for clamping the flanges of the oil and gas pipeline;

[0012] The driver, of which there are two, is connected to the two grippers respectively, for driving the grippers;

[0013] A rotary joint, wherein the connecting pipe of the rotary joint is fixedly installed at the end of the delivery pipe away from the sealing disc, and the rotary joint is connected to the delivery pipe;

[0014] A geared motor, wherein the output shaft of the geared motor is connected to the end of the support shaft away from the sealing disc;

[0015] A detection component is located between the two sealing discs.

[0016] The beneficial effects of this utility model are:

[0017] The combination of structures such as delivery pipe, rotary joint, support shaft and geared motor can drive the oil and gas pipeline to rotate circumferentially. Combined with the linear module, rotary disk and detector in the detection component, it can perform multi-angle flaw detection on flange welds and pipe body.

[0018] Through the synergistic action of structures such as double sealing discs, clamps and actuators, synchronous sealing and reliable clamping of flanges at both ends of oil and gas pipelines are achieved, reducing the number of repeated clamping operations, and gas supply and air tightness testing are completed during the rotation of oil and gas pipelines.

[0019] This equipment integrates airtightness testing and flaw detection in the same workstation, reducing pipeline turnover, testing time, and operation, and effectively improving the efficiency of oil and gas pipeline failure detection. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 2 and Figure 3In one embodiment of this utility model, an oil and gas pipeline failure analysis device is provided, including a sealing disc 5, a delivery pipe 4, a support shaft 6, a clamp 100, a driver 200, a rotary joint 3, a geared motor 8, and a detection component 300.

[0026] There are two sealing discs 5, which are used to seal the flanges of oil and gas pipelines. The diameter of the sealing discs 5 is larger than that of the flanges of oil and gas pipelines. Rubber stops can also be set on the side of the sealing discs 5 that are close to each other, so that they can have better coaxiality and sealing performance when they abut against the flanges of oil and gas pipelines.

[0027] The delivery pipe 4 is fixedly installed at the center of a sealing plate 5. The delivery pipe 4 is connected to the sealing plate 5. The delivery pipe 4 is used to support the sealing plate 5 on the same side and can deliver gas into the oil and gas pipeline during operation.

[0028] The support shaft 6 is fixedly installed at the center of another sealing disc 5. The support shaft 6 is used to support the sealing disc 5 on the same side and transmit torque.

[0029] There are two clamps 100, which are respectively installed on two sealing discs 5 to clamp the flanges of the oil and gas pipeline, thereby ensuring that the sealing discs 5 and the flanges of the oil and gas pipeline are fully in contact.

[0030] There are two drivers 200, which are connected to two grippers 100 respectively to drive the grippers 100 so that the grippers 100 can open and close.

[0031] The rotary joint 3 is an existing component with a structure including a sealing rotating sleeve, a connecting pipe, and an input pipe. The connecting pipe of the rotary joint 3 is fixedly installed at the end of the conveying pipe 4 away from the sealing plate 5, and the rotary joint 3 is connected to the conveying pipe 4. The input pipe of the rotary joint 3 is connected to an external air source device during operation. The rotary joint 3 ensures that the stationary air source device and the rotating conveying pipe 4 are always connected.

[0032] The gas source equipment consists of existing components including an air pump, a gas storage tank, a pressure gauge, valves, and a control cabinet. The air pump is responsible for compressing external gases (such as nitrogen or air) and delivering them to the gas storage tank for storage, forming a stable gas source. The pressure gauge monitors the system pressure in real time to ensure that the inflation process is controllable and to realize inflation, pressure holding, and pressure release operations. During testing, the gas source equipment injects gas into the pipeline through a rotary joint, and the pressure change is observed through a pressure holding test to determine whether there are leaks or structural defects in the oil and gas pipeline.

[0033] The output shaft of the geared motor 8 is connected to the end of the support shaft 6 away from the sealing disc 5, and is used to provide rotational power to the support shaft 6, thereby rotating the oil and gas pipeline circumferentially.

[0034] The detection component 300 is located between the two sealing discs 5; the detection component 300 is used to place oil and gas pipelines and perform flaw detection operations.

[0035] Please see Figure 2 In some embodiments of this utility model, the clamp 100 may optionally include a support plate 105, a rotating seat 103, a second transmission rod 102, and a first transmission rod 101.

[0036] The support plate 105 located on the side of the rotary joint 3 is sleeved on the conveying pipe 4, and the support plate 105 located on the side of the geared motor 8 is sleeved on the support shaft 6. The diameter of the support plate 105 is larger than that of the sealing plate 5. After being driven by the driver 200, the support plate 105 can move linearly and reciprocally along the horizontal.

[0037] The rotating seat 103 is fixedly installed on the sealing disk 5. There are 2 to 6 rotating seats 103, which are evenly distributed along the circumference of the sealing disk 5.

[0038] The side wall of the second transmission rod 102 is rotatably mounted on the rotating seat 103, so that the second transmission rod 102 can swing around the rotating seat 103.

[0039] One end of the first transmission rod 101 is rotatably mounted on the end of the second transmission rod 102 away from the center line of the sealing disk 5, and the other end of the first transmission rod 101 is rotatably mounted on the support disk 105; the first transmission rod 101 is used to convert the linear movement on the support disk 105 into the swinging motion on the second transmission rod 102.

[0040] In this embodiment, the clamp 100 also includes a guide wheel 104, which is rotatably mounted on the end of the second transmission rod 102 near the center line of the sealing disc 5. The guide wheel 104 can avoid scratching the flange by rolling contact during the clamping of the oil and gas pipeline flange.

[0041] Please see Figure 2 In some embodiments of this utility model, optionally, the oil and gas pipeline failure analysis device further includes guide rods 9, which are fixedly installed on the sealing plate 5. The number of guide rods 9 is 2 to 6, and the guide rods 9 are evenly distributed along the circumference of the sealing plate 5. The support plate 105 has through holes for aligning the guide rods 9, and the guide rods 9 are slidably assembled in the through holes.

[0042] Specifically, when the support plate 105 moves horizontally back and forth, the through hole slides along the guide rod 9. By setting multiple guide rods 9, the support plate 105 can be supported and the translation accuracy can be improved.

[0043] Please see Figure 2 In some embodiments of this utility model, optionally, the driver 200 includes a support platform 202, a cylinder 203, and a circular slide rail 201.

[0044] Cylinder 203 is fixedly installed on support platform 202. There are two to four cylinders 203, which are evenly distributed along the circumference of support platform 202. Correspondingly, support platform 202 is provided with through holes for the push rod end of cylinder 203 to pass through.

[0045] The circular slide rail 201 is an existing component with a circular track and a slider. The circular track of the circular slide rail 201 is fixedly installed on the support plate 105, and the push rod end of the cylinder 203 is fixedly installed on the slider of the circular slide rail 201. During operation, the circular track rotates with the support plate 105, while the slider slides on the circular track and does not rotate with the circular track. This transmits the linear motion of the cylinder 203 to the support plate 105. The linear drive and rotational action do not affect each other.

[0046] Please see Figure 1 In some embodiments of this utility model, the oil and gas pipeline failure analysis device may optionally include a trolley 2, a pad frame 1, and a bearing seat 7.

[0047] There are two trolleys 2; trolley 2 is an existing component with a structure such as handles, a body and casters.

[0048] There are two pads 1, and the two pads 1 are fixedly installed on the trolley 2 respectively; the pads 1 are used to compensate for the installation height.

[0049] There are two bearing seats 7. One bearing seat 7 is rotatably assembled with the conveying pipe 4, and the other bearing seat 7 is rotatably assembled with the support shaft 6. The two bearing seats 7 are used to support the conveying pipe 4 and the support shaft 6 respectively, ensuring smooth rotation.

[0050] The bearing housing 7, rotary joint 3 and support platform 202 located on one side of the conveying pipe 4 are fixedly installed on the pad 1 on the same side. The bearing housing 7, geared motor 8 and support platform 202 located on one side of the support shaft 6 are fixedly installed on the pad 1 on the same side.

[0051] Specifically, all components on the pad frame 1 can be moved by the trolley 2, making it convenient for transfer and clamping.

[0052] Please see Figure 3 In some embodiments of this utility model, the detection component 300 may optionally include a roller bracket 305, a linear module 304, a support rod 303, a rotating disk 302, and a detector 301.

[0053] The roller bracket 305 is an existing component with structures such as rotating rollers and seat boxes. The rotating rollers are distributed in a rectangular array, and the center line of the rotating rollers is set parallel to the center line of the oil and gas pipeline. The roller bracket 305 is used to place the oil and gas pipeline and allows the oil and gas pipeline to rotate circumferentially.

[0054] The linear module 304 is fixedly installed on the side wall of the roller bracket 305 and is set horizontally. The linear module 304 is an existing component with a screw, screw nut, slide, housing and linear guide rail. The slide can be moved and adjusted by handwheel drive or servo motor drive.

[0055] The lower end of the support rod 303 is fixedly installed on the slide of the linear module 304, and the support rod 303 is set vertically; the support rod 303 will move horizontally back and forth with the slide of the linear module 304.

[0056] The rotating disk 302 is an existing component with an upper disk body, a lower disk body, a spring piece, and a groove. The upper disk body and the lower disk body are rotatably assembled. The spring piece is fixedly installed on the lower disk body. Grooves are evenly provided on the circumferential side of the upper disk body. The spring piece engages with one of the grooves. The lower disk body of the rotating disk 302 is fixedly installed on the upper end of the support rod 303.

[0057] The detector 301 is fixedly installed on the upper plate of the rotating disk 302. The detector 301 is used to inspect oil and gas pipelines. The detector 301 can be equipped with non-destructive testing equipment such as ultrasonic or X-ray. The detector 301 is manually turned and adjusted by the swing of the rotating disk 302 to change the orientation of the detector 301. This allows for convenient inspection of the weld between the left flange and the pipe body facing left front, or the weld between the right flange and the pipe body facing right front, or the pipe body facing forward, making it more flexible to use.

[0058] In one embodiment of this utility model, the usage process of an oil and gas pipeline failure analysis device is as follows:

[0059] Preparation involves moving all components on the two side pads 1 using the trolley 2 to approach the end of the oil and gas pipeline. The two sealing discs 5 then seal the flanges at both ends of the oil and gas pipeline. The clamp 100 cooperates with the driver 200 and is guided by the guide rod 9 to achieve clamping, ensuring end sealing.

[0060] In the flaw detection work, the geared motor 8 drives the support shaft 6 to rotate, causing the oil and gas pipeline to rotate circumferentially. The roller bracket 305 in the detection component 300 supports the pipeline and allows it to rotate circumferentially. The linear module 304 works in conjunction with the rotary disk 302 to realize the horizontal movement and angle adjustment of the detector 301, and to perform non-destructive testing on the oil and gas pipeline.

[0061] For air tightness testing, the delivery pipe 4 is connected to an external air source device via a rotary joint 3. During the rotation of the pipe, air is injected and maintained to complete the air tightness test.

[0062] This equipment integrates airtightness testing and flaw detection in the same station, reducing the number of turnovers and repeated clamping, and improving the detection efficiency of failure analysis.
