Technical Field
[0001] This disclosure generally relates to the technical field of pipeline pig launching and receiving devices, and specifically to an adjustment mechanism for 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 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, when dealing with various pipelines with long transport distances, the ability to accurately and conveniently adjust the relative position of the pipeline pig to the pipeline becomes particularly important. Currently, most pipeline pig launching devices suffer from the drawbacks of bulky overall structure and lack of flexibility, resulting in excessive time spent on position adjustment during pig launch and low launch efficiency.

[0031] 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.
[0032] 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.
[0033] Example 1
[0034] Please refer to Figure 1 The schematic diagram shown in this embodiment illustrates the structure of an adjustment mechanism for a pipeline pig dispatching and receiving device. The device includes: a vehicle body 1, which forms an installation carrier, and is equipped with a pushing component and a supporting component for pushing and supporting the pipeline pig 2, respectively; the vehicle body 1 also includes an adjustment mechanism for adjusting the posture of the vehicle body 1 and the position of the supporting component, the adjustment mechanism including:
[0035] The first adjustment assembly includes two body adjustment units 3; the two body adjustment units 3 are respectively disposed at the front and rear ends of the vehicle body 1; the body adjustment unit 3 includes: a first lateral adjustment part and a first longitudinal adjustment part, the first lateral adjustment part and the first longitudinal adjustment part are respectively used to control the vehicle body 1 to move along a first direction and a second direction;
[0036] The second adjustment component is disposed on the vehicle body 1 and connected to the bottom of the carrier component. The second adjustment component includes a second lateral adjustment part and a second longitudinal adjustment part. The second lateral adjustment part is used to drive the carrier component to move along a third direction so that the carrier component extends into the receiving and launching tube at the front end of the vehicle body 1. The second longitudinal adjustment part is used to drive the carrier component to move along a second direction so that the carrier component moves towards or away from the receiving and launching tube. The first direction, the second direction and the third direction are perpendicular to each other, and the first direction is parallel to the width direction of the vehicle body 1, the second direction is parallel to the height direction of the vehicle body 1, and the third direction is parallel to the length direction of the vehicle body 1.
[0037] In this embodiment, an adjustment mechanism is mainly proposed on the vehicle body 1 for adjusting the posture of the vehicle body 1 and the position of the pushing component. This mechanism is used to solve the problems of long time consumption and inconvenient operation when the vehicle body 1 is aligned with the pipeline to be cleaned or the receiving and launching tube in front of the pipeline to be cleaned. Since most of the ports of the receiving and launching tubes are equipped with seals, in order to prevent the pipeline pig 2 from damaging the seals when it enters the receiving and launching tube, the arc plate 12 of the bearing component used to carry the pipeline pig 2 is generally extended into the receiving and launching tube (the arc plate 12 covers the seals). In this way, the pipeline pig 2 will not come into contact with the seals when it is pushed into the receiving and launching tube.
[0038] In view of this, the adjustment mechanism includes a first adjustment component and a second adjustment component, respectively used to adjust the vehicle body 1 and the load-bearing component; specifically, the first adjustment component includes body adjustment units 3 disposed at the front and rear ends of the vehicle body, and each body adjustment unit 3 includes a first lateral adjustment part and a first longitudinal adjustment part, which can adjust the position of the vehicle body 1 in the Y direction and Z direction respectively; correspondingly, the first direction and the second direction can be referenced respectively. Figure 1 The direction of the middle arrows Y and Z.
[0039] Furthermore, the second adjustment component is disposed on the vehicle body 1 and connected to the bottom of the load-bearing component, and is used to adjust the position of the load-bearing component. The second adjustment component also includes a second lateral adjustment part and a second longitudinal adjustment part, which can adjust the position of the load-bearing component in a third direction and a second direction. The third direction can be referred to in reference. Figure 1 The direction of the middle arrow X; the design of the second lateral adjustment part allows the carrier component to extend into the receiving tube, while the design of the second longitudinal adjustment part is used to control the alignment of the carrier component with the receiving tube.
[0040] It needs to be explained that the launcher / receiver tube is a variable-diameter structure located at the port of the pipeline to be cleaned. The diameter is smaller further away from the vehicle body 1, and larger closer to the vehicle body 1. The end of the launcher / receiver tube near the arc-shaped plate 12 (i.e., closer to the vehicle body 1) has a concealed door, and a circumferential seal is provided at the port of the launcher / receiver tube near the arc-shaped plate 12. This seal improves the sealing of the internal space of the launcher / receiver tube, ensuring that the high-pressure gas filling the tube can launch the pig 2 to the required travel distance. Furthermore, the vehicle body 1 is also equipped with... Other components that complete the pushing of the pig 2 include, for example, the "pushing component" and the "carrying component" mentioned above. The pushing component is used to perform the action of pushing the pig 2, and its structure can be a hydraulic cylinder with a large stroke or a more convenient and space-saving multi-stage push rod. The carrying component is used to place the pig 2, and its structure can be an arc plate 12. The second adjustment component in this application is connected to the arc plate 12, thereby driving the arc plate 12 to move flexibly. The specific structure of the pushing component and the carrying component is not specifically limited in this application.
[0041] In a preferred embodiment, see Figure 2 and Figure 3 The body adjustment unit 3 includes:
[0042] At least two lifting rods 4 are respectively provided on both sides of the vehicle body 1. The lifting rods 4 can reciprocate along the second direction and constitute the first longitudinal adjustment part of the vehicle body adjustment unit 3.
[0043] A bidirectional pushing structure is provided between the two lifting rods 4 contained in the same body adjustment unit 3. The top of the bidirectional pushing structure is connected to the bottom of the vehicle body 1. The bidirectional pushing structure constitutes the first lateral adjustment part of the body adjustment unit 3. The bidirectional pushing structure has two pushing ends that can move in opposite directions. The two pushing ends are respectively connected to the outer walls of the two lifting rods 4 in the first longitudinal adjustment part. The pushing ends are used to drive the lifting rods 4 to reciprocate along the first direction.
[0044] Specifically, the type of lifting rod 4 can be a hydraulic rod, which drives the vehicle body 1 to adjust through its own lifting control. Therefore, the lifting end of the lifting rod 4 needs to be connected to the bidirectional push structure at the bottom of the vehicle body 1. After the lifting rod 4 is activated, it can drive the vehicle body 1 to move in the Z direction through the bidirectional push structure connected to the bottom of the vehicle body 1. The bidirectional push structure is the main structure of the first lateral adjustment part. It includes two retractable push ends that can move in opposite directions and are connected to the lifting end of the lifting rod 4. The push ends drive the lifting rod 4 to move its position. In this way, under the control of the bidirectional push structure, the two lifting rods 4 in the same vehicle body adjustment unit 3 can control the position adjustment of the vehicle body 1 in the first direction by relaying the direction of movement and extension.
[0045] In a preferred embodiment, see Figure 4 The two-way push structure includes:
[0046] A connecting beam 5 is provided, the top of which is connected to the bottom of the vehicle body 1; at least two driving components are provided in the middle of the connecting beam 5, and the pushing ends of the two driving components are arranged opposite each other.
[0047] Both drive components have sleeves 6 at their pushing ends. A fixing block 7 is provided at the end of the sleeve 6 away from the other sleeve 6. The fixing block 7 is connected to the inner push shell 9 via a pin 8. The inner push shell 9 is slidably disposed within the connecting beam 5. The end of the inner push shell 9 away from the drive component is connected to the lifting rod 4.
[0048] Specifically, the driving component can be a hydraulic cylinder. During installation, the pushing ends of the two hydraulic cylinders can be set opposite each other. In addition, a sleeve 6 is provided inside the connecting beam 5. The sleeve 6 is set on the pushing end of the driving component to provide installation space for the fixing block 7. The fixing block 7 is fixed to the pushing inner shell 9 by the pin 8 and then connected to the lifting rod 4 by the pushing inner shell 9, instead of being directly connected through the pushing end. This makes the pushing end of the driving component and the lifting rod 4 more stable when fixed.
[0049] In a preferred embodiment, see Figure 3 The supporting component includes an arc-shaped plate 12 corresponding to the pushing end of the pushing component; the arc-shaped plate 12 is used to place the pig 2;
[0050] The second adjustment assembly includes: a base frame 10, with a plurality of first pushers 11 at the bottom of the base frame 10 for driving the base frame 10 to move along a second direction; a support plate 13 is provided on the upper surface of the base frame 10, and the side of the support plate 13 away from the base frame 10 is connected to the arc plate 12, and the first pushers 11 constitute the second longitudinal adjustment part of the second adjustment assembly.
[0051] Specifically, the base frame 10 forms a mounting surface for a support plate 13, which in turn supports the arc plate 12, thereby supporting the placement of the pig 2. The first pusher 11 can also be a hydraulic cylinder. Since both the pig 2 and the arc plate 12 have certain specifications, the number of first pushers 11 can be set to a uniform number. In addition, in order to ensure the connection stability and versatility of the arc plate 12 (different pigs 2 may require arc plates 12 of different specifications for support), multiple detachable arc support plates 14 that match the arc plate 12 are also provided on the top of the support plate 13, thereby greatly improving the usability of the adjustment mechanism.
[0052] In a preferred embodiment, see Figure 3 The base frame 10 also has sliding grooves 16 on both sides of its side walls;
[0053] Multiple sliding wheels 15 are arranged at the bottom of the support plate 13, and the sliding wheels 15 are slidably disposed inside the slide groove 16; a second pusher 21 is provided at the end of the base frame 10 near the rear wheel of the vehicle body 1, and the second pusher 21 constitutes the second lateral adjustment part of the second adjustment assembly; the pushing end of the second pusher 21 passes through the base frame 10 and is connected to the bottom of the support plate 13, and is used to drive the support plate 13 to move along the slide groove 16, so as to drive the arc plate 12 to move in a third direction, thereby extending into the ball receiving tube at the front end of the vehicle body 1.
[0054] Specifically, the structure of the second lateral adjustment part is described here. The opposing side walls of the base frame 10 are provided with grooves 16 extending along the length of the vehicle body 1. Multiple sliding wheels 1 located within the grooves 1 are arranged on both sides of the bottom of the support plate 13. A second pushing member 21 is also provided on the base frame 10. The second pushing member 21 passes through the base frame 10 and connects to the support plate 13, thereby driving the support plate 13 to move along the grooves 16, thus driving the arc-shaped plate 12 to move in a third direction. The type of the second pushing member 21 can also be a hydraulic push rod; no special limitation is made here.
[0055] In a preferred embodiment, see Figure 3 The second adjustment component also includes a locking structure, which is disposed at the bottom of the support plate 13 and adjacent to the sliding wheel 15.
[0056] The locking structure includes a connecting plate 17, which has an extension extending into the slide groove 16. The extension is provided with a locking member 18, which has a locking end that can move in a second direction. The locking end can extend toward the bottom of the slide groove 16 and contact the slide groove 16 to constrain the movement of the sliding wheel 15.
[0057] Specifically, since the entire vehicle body 1 is quite large, when controlling the second lateral adjustment part to drive the load-bearing component to move along a third direction, the position is only guaranteed by the operation and stopping of the second pusher 21. Therefore, when pushing the pig 2, the support plate 13 may move due to the force between the pig and the arc plate 12. So the second adjustment component also includes a locking structure to fix and lock the position of the support plate 13. In actual application, after the sliding wheel 15 moves to the designated position, the locking end of the locking member 18 can be controlled to extend and abut against the bottom of the slide groove 16, thereby blocking the movement of the sliding wheel 15.
[0058] Based on the above description, this application proposes an adjustment mechanism for a pipeline pig launching and receiving device. Its specific working principle is as follows: First, control the vehicle body 1 (by controlling the front wheel assembly 19 and the rear wheel assembly 20 on the vehicle body 1) to move to the approximate position of the launching and receiving tube. Then, the attitude of the vehicle body 1 and the position of the load-bearing assembly can be further adjusted through the first adjustment assembly and the second adjustment assembly. Specifically, the bidirectional pushing structure can control the alternating extension and retraction of the lifting rod 4 on the same side to adjust the relative position of the launching and receiving tubes and the vehicle body 1. After the vehicle body position is confirmed, the height of the vehicle body 1 can be adjusted by controlling the lifting rod 4 in the vehicle body adjustment unit so that the pushing end of the pushing component can be aligned with the launching and receiving tubes. When adjusting the bearing component, the lifting and lowering of the base frame 10 can be directly controlled by the first pushing component 11, thereby raising or lowering the base frame 10 and the supporting components such as the support plate 13 and the arc plate 12 that support the pig 4. Next, since the arc plate 12 needs to extend a certain distance into the launching and receiving tubes, the second pushing component 16 needs to be activated to move the arc plate 12 closer to the launching and receiving tubes. Accordingly, the control and adjustment of the launching and receiving device can be achieved by relying on the adjustment mechanism. However, it should be noted that the above description is used to illustrate the adjustment principle of the adjustment mechanism and does not limit the order of adjustment. The specific adjustment methods need to be adjusted according to the actual situation, which will not be elaborated further here.
[0059] 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.
