Description

Technical Field

[0001] This disclosure generally relates to the technical field of pipeline pig launching and receiving devices, and specifically to a pipeline pig launching and receiving device. Background Technology

[0002] During operation, long-distance oil and gas pipelines can accumulate impurities on their inner walls due to various factors (such as corrosion, scaling, and sand particles), affecting their transport efficiency and safety. To maintain pipeline flow and extend their service life, regular cleaning is necessary.

[0003] Traditional pipeline cleaning methods involve physical cleaning using pipeline pigs. However, as pipeline diameters and lengths increase, the dispatching and receiving of pigs becomes increasingly difficult, especially at gas transmission stations where flammable gases are present, requiring explosion-proof measures. To improve the efficiency and safety of pipeline cleaning operations, new types of pipeline pig dispatching and receiving devices are constantly emerging.

[0004] However, current pipeline pig dispatching devices often require larger and more complex pushing structures to prepare the pig for dispatching or receiving when dealing with pipelines with long transport distances or large specifications in order to ensure the transport requirements. This not only increases the space occupied by the pushing structure, but also affects the specifications of the pipelines it can enter, making the overall pig dispatching device more cumbersome and hindering its flexible movement. To address these issues, we propose a pipeline pig dispatching device to solve the above problems. Utility Model Content

At the same time, in cooperation with the support component, it further facilitates the pushing and launching of the pig. Attached Figure Description

[0032] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Example 1

[0035] Please refer to Figure 1 and Figure 2 The schematic diagrams shown in this embodiment, including a cross-sectional view and an overall structural diagram of a pipeline pig dispatching and receiving device, include:

[0036] Vehicle body 1, vehicle body 1 is used to form an installation carrier;

[0037] Pushing component 2 is mounted on vehicle body 1. Pushing component 2 includes multi-stage push rods that cooperate with each other. The multi-stage push rods are used to provide different strokes of pushing force to the pig 4.

[0038] The carrying component 3 is set on the pig receiving and dispatching vehicle body 1 and is correspondingly set to the pushing end of the multi-stage push rod. The carrying component 3 includes an arc plate 5, which is used to place the pig 4. When the pig 4 is placed on the arc plate 5, the multi-stage push rod can push the pig 4 into the pipeline to be cleaned.

[0039] Specifically, in this embodiment, to facilitate the movement of the pipeline cleaning device, the overall structure carrier is a vehicle body 1. The vehicle body 1 has the basic structure of a vehicle and can be driven to the port of the corresponding pipeline to be cleaned under the control of technicians to complete the subsequent launch / pushing of the pipeline cleaning device 4. Here is a brief description of the pipeline cleaning device 4. The pipeline cleaning device 4 is specially designed for cleaning long-distance, large-diameter pipelines. The outer surface of the pipeline cleaning device 4 is made of elastic material, and its natural volume is slightly larger than the diameter of the pipeline. Therefore, when the pipeline cleaning device 4 is pushed into the pipeline to be cleaned, it can fit tightly against the inner wall of the pipeline. Through the high-speed movement of the pipeline cleaning device 4 in the pipeline to be cleaned, corrosion, scale, sand particles, etc. in the pipeline to be cleaned can be pushed out by the pipeline cleaning device 4, thereby achieving the purpose of cleaning the pipeline.

[0040] Furthermore, the vehicle body 1 is also equipped with a corresponding pushing component 2 and a carrying component 3. As the names suggest, the pushing component 2 and the carrying component 3 are used to push and carry the pig 4, respectively. Since the specifications of the pig 4 need to match the specifications of the pipeline to be cleaned, and the specifications of the pipeline to be cleaned also determine how much thrust is required, in order to provide sufficient thrust without occupying too much space, the pushing component 2 includes multi-stage push rods that cooperate with each other. This design allows the multi-stage push rods to provide different strokes of pushing force to meet the different launch requirements of the pig. In addition, the pig 4 also requires a corresponding carrying component 3 when it is initially placed. After placement, the pushing component 2 pushes it into the pig launcher tube 12, thereby completing the preparation of the pig launcher device when launching the pig 4.

[0041] In a preferred embodiment, see Figure 1 , Figure 4 and Figure 5 The multi-stage push rod includes: a support frame 6 and a first-stage push rod 7, a second-stage push rod 8 and a third-stage push rod 9 arranged sequentially on the support frame 6;

[0042] The support frame 6 is mounted on the vehicle body 1, and at least one sliding groove 10 is provided on each of the two side walls of the support frame 6 that are parallel to the length direction of the vehicle body 1.

[0043] The secondary push rod 8 includes at least: an outer shell 81 and an intermediate shell 82 slidably disposed inside the outer shell 81, and the secondary push rod body 83 is also disposed inside the intermediate shell 82; multiple pulleys 11 are arranged on both sides of the bottom of the outer shell 81, and the pulleys 11 are slidably disposed in the slide groove 10; the pushing end of the tertiary push rod 9 is connected to the bottom of the outer shell 81; the primary push rod 7 is disposed on the top of the outer shell 81, and the pushing end of the primary push rod 7 is connected to the intermediate shell 82 exposed outside the outer shell 81.

[0044] Specifically, in this embodiment, the multi-stage push rod consists of a support frame 6, a first-stage push rod 7, a second-stage push rod 8, and a third-stage push rod 9. The support frame 6 has sliding grooves 10 on both sides to allow the pulleys 11 to slide. The extension direction of the sliding grooves 10 is consistent with the length direction of the vehicle body 1, which allows the multi-stage push rod to provide a greater stroke. In addition, the number of sliding grooves 10 can be set to multiple and arranged in parallel with each other. This makes the height of the first-stage push rod 7, the second-stage push rod 8, and the third-stage push rod 9 adjustable, making it more convenient to use.

[0045] Furthermore, pulleys 11 are respectively provided on both sides of the outer shell 81 of the secondary push rod 8. When the tertiary push rod 9 is started, it can push the outer shell 81 to slide along the slide groove 10, which is equivalent to the first stage of the multi-stage push rod. Inside the outer shell 81, there is a long intermediate shell 82 and a secondary push rod body 83 fixed inside the intermediate shell 82. The secondary push rod body 83 is the pushing end that contacts the pig 4. The pushing end of the secondary push rod body 83 itself is equivalent to the first stage of the push. Finally, the top of the outer shell 81 is also provided with There is a first-stage push rod 7, and the pushing end of the first-stage push rod 7 is connected to the intermediate shell 82 exposed outside the outer shell 81. Under the push of the first-stage push rod 7, the intermediate shell 82 can also slide along the length direction of the outer shell 81, which is equivalent to a first-stage push. It can be seen that the multi-stage push rod in this application is a three-stage push rod, which can meet the pushing requirements of the pig 4 without too many complex structures. However, it should be noted that this application does not limit the number of pushing stages of the multi-stage push rod, and it can also be designed as a push rod with more or fewer stages.

[0046] In a preferred embodiment, see Figure 1 The secondary push rod body 83 includes: a push housing 84, which is connected to the outside of the push end of the secondary push rod body 83 and is slidably disposed within the intermediate housing 82; the push housing 84 and the intermediate housing 82 are respectively provided with corresponding limiting structures at both ends, which are used to constrain the movement stroke of the intermediate housing 82 and the push housing 84; the primary push rod body of the primary push rod 7 and the secondary push rod body 83 are also provided with hydraulic locks for controlling their respective push rods to remain stationary.

[0047] Specifically, the secondary push rod body 83 also includes a push housing 84 connected to its own push end. This serves two purposes: firstly, by setting a limiting structure on its exterior, the stroke of the secondary push rod body 83 can be controlled; secondly, it increases the contact area between the secondary push rod body 83 and the pig 4, facilitating pushing. Furthermore, the intermediate housing 82 can also slide along the outer housing 81 under the push of the primary push rod 7. Therefore, a limiting structure is also provided on the exterior of the intermediate housing 82. This limiting structure can be a cooperating protruding structural plate or other limiting structure; no specific limitations are specified here. For details on the limiting structure, please refer to [link to relevant documentation]. Figure 4 The protrusions at the front of the push rods at each level are shown.

[0048] The hydraulic locks on the primary push rod body 7 and the secondary push rod body 83 are compatible with each level of push rod (the primary, secondary, and tertiary push rods all use hydraulic push rods). With the cooperation of the control system, if the secondary push rod moves to the designated position, the hydraulic lock can be activated to fix its position. Then, when controlling other push rods in the future, it will not affect the already locked push rod, which greatly improves the control and pushing stability of the multi-stage push rods.

[0049] In a preferred embodiment, see Figure 4 The supporting component 3 also includes: a lifting adjustment part disposed at the bottom of the arc plate 5, which is used to adjust the height of the arc plate 5; and multiple conductive strips 51 extending along the length direction of the arc plate 5 are also disposed on the upper surface of the arc plate 5.

[0050] Specifically, since the arc plate 5 is used to support the pig 4, the shape of the arc plate 5 needs to meet the placement requirements of the pig 4; when pushing the pig 4 into the pipeline, the position of the arc plate 5 needs to be adjusted by lifting to align with the pipeline. The lifting adjustment part can adopt a structure such as a hydraulic push cylinder, but there are no special limitations.

[0051] In addition, during the load-bearing process, the arc plate 5 often comes into contact with the pig 4, and the pig 4 is also relatively large. It is unavoidable that the two will have relative friction. Therefore, in order to prevent the friction from generating sparks and other damage to the hydraulic system, multiple conductive strips 51 are provided in the length direction of the arc plate 5, such as brass strip metal strips.

[0052] In a preferred embodiment, see Figure 2 The receiving and launching device also includes: a receiving and launching tube 12, which is used in conjunction with the pushing component 2 and the carrying component 3 to push the pig 4 into the pipeline to be cleaned;

[0053] The ball receiving and launching tube 12 is disposed between the pipe to be cleaned and the vehicle body 1, and the vehicle body 1 is fixed to one of the ports of the ball receiving and launching tube 12 by a fixing component, so that the arc plate 5 can extend into the ball receiving and launching tube 12.

[0054] The side wall of the launcher / receiver tube 12 is also provided with an air supply end that is connected to its interior; after the pusher assembly 2 pushes the pig 4 into the launcher / receiver tube 12, high-pressure gas is connected through the air supply end, and then the high-pressure gas launches the pig 4 into the pipeline to be cleaned.

[0055] Specifically, the transceiver also includes a transceiver tube 12, which is set at the port of the pipeline to be cleaned. The vehicle body 1 needs to drive to the end of the transceiver tube 12 away from the pipeline to be cleaned, push the pig 4 into the transceiver tube 12 through the pushing component, and then launch it. That is, the high-pressure gas is activated and the high-pressure gas launches the pig 4 into the pipeline to be cleaned.

[0056] It should be explained that the launcher / receiver tube 12 has a variable diameter structure, with a smaller diameter further away from the vehicle body 1 and a relatively larger diameter closer to the vehicle body 1. The pushing distance required by the pushing component 2 is also controlled by technicians. At the same time, the end of the launcher / receiver tube 12 near the arc plate 5, that is, closer to the vehicle body 1, has a concealed door, and a circumferential seal is provided at the port of the launcher / receiver tube 12 near the arc plate 5. The seal is used to improve the sealing of the internal space of the launcher / receiver tube 12, thereby ensuring that the high-pressure gas can launch the pig 4 to the required stroke. In addition, since the launcher / receiver tube 12 is used frequently, it is mostly directly fixed inside the pipeline site and directly fixed to the pipeline port. The other end of the launcher / receiver tube 12 can be directly connected to the vehicle body 1.

[0057] In a preferred embodiment, see Figure 2 The vehicle body 1 includes a front wheel assembly 13 and a rear wheel assembly 14;

[0058] The front wheel assembly 13 and the rear wheel assembly 14 are respectively connected to the front axle assembly and the rear axle assembly; the front axle assembly and the rear axle assembly cooperate with each other to control the movement and steering of the vehicle body 1.

[0059] Specifically, the travel of vehicle body 1 is inseparable from the wheel assembly. In this embodiment, vehicle body 1 includes the necessary structure of a current vehicle, and the front wheel assembly 13 and the rear wheel assembly 14 are respectively connected to the front axle assembly and the rear axle assembly. The front axle assembly is designed to meet the requirements of hydraulic steering. The steering system is connected to the front axle through components such as steering rods and steering gears, enabling the driver to control the direction of the vehicle. The rear axle assembly is designed to meet the transmission requirements. It is equipped with components such as drive shafts and differentials, which are responsible for transmitting power to the wheels. In this way, the stable movement of vehicle body 1 is guaranteed, and the launching efficiency of the pig will be greatly accelerated.

[0060] In a preferred embodiment, see Figure 3 The vehicle body 1 is also equipped with an explosion-proof box 15 located at the rear of the vehicle body 1. The explosion-proof box 15 is used to provide a stable electrical connection and control for the transceiver device.

[0061] Specifically, since the types of pipelines to be cleaned are different, if the pipeline is to be cleaned in the face of a flammable gas transmission station, then explosion-proof measures must be taken. Therefore, in this embodiment of the application, the vehicle body 1 is also equipped with an explosion-proof box 15 located at the rear of the vehicle body 1, which is used to protect electrical equipment in a flammable and explosive environment and prevent fire or explosion accidents caused by electrical faults or improper operation.

[0062] Based on the above description, this application provides a pipeline pig launching and receiving device, the specific working principle of which is as follows: First, the vehicle body 1 is driven to the front of the launching and receiving tube 12 of the pipeline to be cleaned. Then, the height of the vehicle body 1 is adjusted according to the position of the pipeline to be cleaned, so that the pushing component 2 is aligned with the pipeline to be cleaned. Then, the pig 4 is placed on the arc plate 5 of the supporting component 3, and the arc plate 5 is adjusted by the lifting adjustment part so that the subsequent pushing component 2 can accurately send the pig 4 into the launching and receiving tube 12. The multi-stage push rod in the pushing component 2 can be activated according to the pushing requirements, which will not be described in detail here. When the pig 4 reaches the designated position, the air supply end of the launching and receiving tube 12 can be connected to high-pressure gas to complete the launch of the pig 4. The pig 4 pushes out the dirt and other waste in the pipeline to be cleaned from the other end, thereby achieving the purpose of cleaning the pipeline.

[0063] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
