Description

Technical Field

[0001] This disclosure generally relates to the technical field of pipeline pig retrieving and dispatching devices, and specifically to a docking structure for a pipeline pig retrieving and dispatching 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 cleaning tools. However, as pipeline diameter and length increase, the dispatching and receiving of pipeline cleaning tools becomes increasingly difficult. Therefore, in order to improve the efficiency and safety of pipeline cleaning operations, new types of pipeline cleaning tool dispatching and receiving devices are constantly emerging.

[0004] However, current pipeline pig launching and receiving devices often require sufficient thrust to push the pig into the launching and receiving canister before launching it into the pipeline to be cleaned when dealing with pipelines with long delivery distances or large specifications. Therefore, the stable docking of the vehicle body and the launching and receiving canister is closely related to the pushing of the pig and also to the launching efficiency of the pig. To address this issue, we propose a docking structure for the pipeline pig launching and receiving device to improve the above problems. Utility Model Content

[0012] According to the technical solution provided in this application, two limiting plates are also provided on one side of the two supporting blocks opposite each other. Each limiting plate is jointly provided on the two guide rods, and each limiting plate corresponds to one supporting block, which is used to constrain the sliding of the supporting block.

[0013] The support block is equipped with a displacement sensor and a pressure sensor; the displacement sensor is used to collect the moving distance of the support block, and the pressure sensor is located on the side of the support block near the limiting plate to monitor the pressure on the support block in real time.

[0014] According to the technical solution provided in this application, the side wall of the support frame near the ball receiving and launching tube forms the mounting surface of the scissor telescopic structure, and two spaced through slots are provided on the mounting surface;

[0015] The scissor-type telescopic structure includes a middle linkage plate and coordinated linkage plates that are movably connected to both ends of the middle linkage plate; the middle part of the middle linkage plate is connected to the middle part of the mounting surface through a rotating shaft, and the ends of different coordinated linkage plates away from the middle linkage plate extend into the corresponding through grooves and are respectively connected to different support blocks.

[0016] According to the technical solution provided in this application, the vehicle body further includes a support assembly for carrying the pipeline pig, the support assembly is disposed at the front end of the vehicle body, and the support assembly includes an arc-shaped plate for placing the pipeline pig;

[0021] Existing pipeline pig launching and receiving devices typically require sufficient thrust to push the pig into the launching and receiving tank when dealing with pipelines with long transport distances or large specifications. In actual pushing processes, if the friction between the pig and the inner wall of the launching and receiving tank is too high, it may cause the vehicle to shake, which greatly affects the pushing of the pig. This application proposes a new docking structure. Before the pig is pushed, the vehicle body is docked and locked to the corresponding launching and receiving tank through the drive unit and the locking unit. At the same time, the scissor telescopic structure ensures that the locking parts in the locking unit can move synchronously, simplifying the control complexity. This docking structure can effectively optimize the pushing process of the pig. Attached Figure Description

Detailed Implementation

[0028] 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.

[0029] 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.

[0030] Example 1

[0031] Please refer to Figure 1 The diagram shown in this embodiment illustrates the docking structure of a pipeline pig dispatching and receiving device. The device includes: a vehicle body 1, which forms an installation carrier, and a pushing component 20 for pushing the pig 2 into the pipeline to be cleaned is provided on the vehicle body 1; the front end of the vehicle body 1 also has a docking structure for cooperating with the pipeline to be cleaned, the docking structure including:

[0032] The docking structure body 3 includes a driving part and a snap-fit ​​part that cooperate with each other; the snap-fit ​​part includes at least two snap-fit ​​pieces 4 arranged opposite each other, which are used to snap onto the outer wall of the receiving and launching tube 5; the receiving and launching tube 5 is arranged correspondingly to the port of the pipe to be cleaned.

[0033] The drive unit includes at least two drive components 6, which are respectively connected to different locking components 4 for driving the locking components 4 to abut against the outer wall of the ball receiving and launching tube 5; wherein, the two drive components 6 are linked and controlled by a scissor telescopic structure 7 to achieve synchronous movement adjustment of the two locking components 4.

[0034] Because current pipeline pig launching and receiving devices often require sufficient thrust to push the pig into the launching and receiving tube before launching it into the pipeline to be cleaned when dealing with pipelines with long delivery distances or large specifications, and the outer surface of the pig 2 is made of elastic material (e.g., rubber), the pig 2 needs to overcome a certain amount of friction when being pushed into the launching and receiving tube. Therefore, in order to ensure the stable pushing of the pig 2, this application proposes a docking structure that can lock the vehicle body 1 to the launching and receiving tube. So even if the pig 2 and the launching and receiving tube generate a large amount of friction, the vehicle body 1 can still be stable, and the entire pushing process will not be disturbed.

[0035] In this embodiment, the vehicle body 1 has a relatively complete conventional vehicle structure, such as wheels 17, a front axle assembly, and a rear axle assembly, enabling the vehicle body 1 to quickly travel to a designated location. Furthermore, the vehicle body 1 is also equipped with other components for pushing the pipeline pig 2, such as the aforementioned "pushing component" and "carrying component." The pushing component is used to perform the action of pushing the pipeline pig 2, and its structure can be a long-stroke hydraulic cylinder or a more convenient, space-saving multi-stage push rod. The carrying component is used to hold the pipeline pig 2, and its structure can be an arc-shaped plate 11 and an adjustment component connected to the arc-shaped plate 11. The entire assembly can also be constructed using cylinders with multiple telescopic directions, thereby driving the arc plate 11 to move flexibly. Importantly, the docking structure body 3 in this application is located at the front end of the vehicle body 1, and its two locking members 4 are used to complete the function of locking with the outside of the launching and receiving tubes. Since the launching and receiving tubes have different specifications, the locking of the locking members 4 is driven by the driving member 6 in the driving unit to adapt to the docking of different launching and receiving tubes. To improve the efficiency and convenience of docking, a scissor-type telescopic structure 7 is also provided between the two driving members 6 to achieve linkage control, ensuring that the two locking members 4 can move synchronously. Specifically, the scissor-type telescopic structure 7 can be found in [reference needed]. Figure 1 The structure shown.

[0036] In a preferred embodiment, see Figure 2 The docking structure also includes: a support frame 8 connected to the front end of the vehicle body 1; two snap-fit ​​pieces 4 arranged along the first direction on the top of the support frame 8; and two drive pieces 6 passing through the opposite side walls of the support frame 8 and connected to the corresponding snap-fit ​​pieces 4.

[0037] Specifically, the docking structure also includes a support frame 8 for supporting the drive unit and the snap-fit ​​unit. The support frame 8 provides reasonable installation space for each component. Snap-fit ​​parts 4 are provided on both sides of the support frame 8, so the first direction here is the length direction of the support frame 8. The function of the drive unit 6 is to drive the snap-fit ​​parts 4. Therefore, the design of the drive unit 6 needs to ensure that its drive end penetrates through the side wall of the support frame 8, thereby connecting with the corresponding snap-fit ​​parts 4 to transmit the driving force to the corresponding snap-fit ​​parts 4.

[0038] It should be noted that there is no specific limitation on the design quantity of the driving component 6 and the locking component 4, and more can be designed. Furthermore, the driving component 6 can be a hydraulic cylinder, and the locking component 4 is bent in shape to tightly engage with the outer wall of the receiving / launching tube 5. A wear-resistant part 12 is provided on the top of the locking component 4, and the locking component 4 contacts the receiving / launching tube 5 through the wear-resistant part 12. The structure of the locking component 4 can be found in [reference needed]. Figure 1 As shown, it is designed with a certain angle to be bent, which can be adapted to be engaged with more receiver tubes 5 (contact and abutment through the corner). If an arc structure is adopted, there are certain requirements for the degree of matching between the curvature of the arc structure and the diameter of the receiver tube 5. At the same time, in order to meet the requirements of lightweighting of the overall receiver device, multiple weight-reducing holes 13 are provided on each engagement piece 4. Finally, due to the frequent contact between the engagement piece 4 and the receiver tube 5, the wear-resistant part 12 can reduce the contact wear between the two, which is beneficial to the service life of the docking structure and the later maintenance.

[0039] The launcher / receiver tube 5 is a variable-diameter structure installed at the port of the pipeline to be cleaned. The diameter is smaller further away from the vehicle body 1, and the diameter is relatively larger closer to the vehicle body 1. At the same time, the end of the launcher / receiver tube near the arc plate 11, that is, closer to the vehicle body 1, has a concealed door. The port of the launcher / receiver tube 5 near the arc plate 11 is equipped with a circumferential seal. The seal is used to improve the sealing of the internal space of the launcher / receiver tube, thereby ensuring that the high-pressure gas can launch the pig 2 to the required stroke. In addition, since the launcher / receiver tube 5 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 5 can be directly connected to the vehicle body 1.

[0040] In a preferred embodiment, two guide rods 9 are provided in the middle of the support frame 8, which are arranged parallel to each other along a first direction; at least two support blocks 10 are slidably provided on the two guide rods 9.

[0041] The support block 10 is connected to the drive end of the drive component 6, and two snap-fit ​​components 4 are respectively disposed on the top of the two support blocks 10.

[0042] Specifically, the support frame 8 is also provided with a guide rod 9 to limit the movement of the snap-fit ​​part 4; the support block 10 is slidably connected to the guide rod 9 through the bearing 18 / sliding sleeve, and the bottom of the snap-fit ​​part 4 is fixed to the support block 10. Under the drive of the drive member 6, the snap-fit ​​part 4 can slide on the guide rod 9. The length of the guide rod 9 and the control stroke of the drive member 6 are set by the technicians in advance.

[0043] In a preferred embodiment, see Figure 3 Two limiting plates 14 are also provided on the opposite side of the two support blocks 10. Each limiting plate 14 is jointly provided on the two guide rods 9, and each limiting plate 14 corresponds to one support block 10, which is used to constrain the sliding of the support block 10.

[0044] The support block 10 is equipped with a displacement sensor 15 and a pressure sensor 16. The displacement sensor 15 is used to collect the moving distance of the support block 10, and the pressure sensor 16 is located on the side of the support block 10 near the limiting plate 14 to monitor the pressure that the support block 10 is subjected to in real time.

[0045] Furthermore, in order to precisely control the movement of the snap-fit ​​component 4, two limiting plates 14 are also set on the opposite side of the two support blocks 10. Each limiting plate 14 is used to restrict the movement of one snap-fit ​​component 4. At the same time, a displacement sensor 15 and a pressure sensor 16 are also set on the support block 10. The displacement sensor 15 is used to collect the movement distance of the support block 10 and generate a corresponding distance signal. The pressure sensor 16 is used to monitor the pressure value between the support block 10 and the limiting plate 14 and generate a corresponding pressure signal. In actual application, if the hydraulic control system finds that the value displayed by the pressure signal is too large, it means that the movement of the snap-fit ​​component 4 is restricted. The distance signal can reflect the real-time movement distance and synchronization of the two snap-fit ​​components 4. In this way, the docking accuracy of the docking structure body 3 and the ball receiving and launching tube 5 can be greatly improved by means of signal monitoring.

[0046] In a preferred embodiment, see Figure 2 and Figure 4 The support frame 8 forms a mounting surface for the scissor telescopic structure 7 near the side wall of the ball receiving and launching tube 5, and two spaced through slots 81 are provided on the mounting surface;

[0047] The scissor telescopic structure 7 includes an intermediate linkage plate 71 and two cooperating linkage plates 72 that are movably connected at both ends of the intermediate linkage plate 71; the middle part of the intermediate linkage plate 71 is connected to the middle part of the mounting surface through a rotating shaft 73, and the ends of different cooperating linkage plates 72 that are away from the intermediate linkage plate 71 extend into corresponding through slots 81 and are connected to different support blocks 10 through pins 82 respectively.

[0048] Specifically, a scissor-type telescopic structure 7 is provided on the side wall of the support frame 8 near the receiving and launching tube 5. The scissor-type telescopic structure 7 is similar in principle to most folding linkage structures. Based on the above structural connection relationship, when the scissor-type telescopic structure 7 moves, the coordinated linkage plate 72 connected to the support block 10 serves as the starting point for the movement, driving the entire scissor-type telescopic structure 7 to move. The other ends of the two coordinated linkage plates 72 are movably connected to the same intermediate linkage plate 71, so that during the movement, the intermediate linkage plate 71 can swing around the pivot 73, and the two coordinated linkage plates 72 are synchronously restricted. Accordingly, this application The embodiment can cleverly solve the problem of movement of the two snap-fit ​​parts 4. In actual application, the vehicle body 1 also includes a support component for carrying the pig 2. The support component is set at the front end of the vehicle body 1 and includes an arc plate 11 for placing the pig 2. Therefore, the rotation connection point between the middle part of the intermediate linkage plate 71 and the mounting surface is set to correspond to the center point of the bottom of the arc plate 11, so that the adjustment of the docking structure body 1 and the movement of the support component will not be disturbed, ensuring that after the docking structure body 3 is snapped with the outside of the receiving and launching tube 5, the support component can smoothly enter the receiving and launching tube 5.

[0049] Based on the above description, this application proposes a docking structure for a pipeline pig launching and receiving device. Its specific working principle is as follows: First, the vehicle body 1 is moved to the approximate position of the launching and receiving cylinder 5. Then, the corresponding adjustment component aligns the vehicle body 1 with the launching and receiving cylinder 5. Finally, the locking part docks with the port of the launching and receiving cylinder 5. Specifically, the following steps are taken: First, the required adjustment direction and distance are determined based on the position information displayed by the displacement sensor 15. Then, based on the obtained data, the drive unit 6 is controlled to perform corresponding actions. The two drive units 6 drive the two locking parts 4 to move synchronously along the two guide rods 9 using the scissor telescopic structure 7, thus opening and closing the two locking parts 4. After reaching the designated position, the drive unit 6 is stopped, thereby achieving the purpose of locking the locking parts 4 onto the outside of the launching and receiving cylinder 5. After the locking parts 4 are locked with the launching and receiving cylinder 5, the pig 2 can be pushed into the launching and receiving cylinder 5 using the pushing component 20 on the launching and receiving device. Subsequent operations will not be elaborated further.

[0050] 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.
