Description

Technical Field

[0001] The utility model relates to the technical field of crude oil pipeline cleaning equipment, in particular to a self-rotating platform for crude oil pipeline cleaning. Background Art

[0002] After long-term service of crude oil pipelines, hard fouling layers will form on the inner wall of the pipelines due to the deposition of components such as wax, asphaltene and colloid in crude oil, which seriously restricts the transportation efficiency and poses potential safety hazards. Meanwhile, before decommissioning and disposal of retired crude oil pipelines, the oil dirt inside the pipelines needs to be cleaned up to the environmental protection and pollution-free standard. However, the geographical pipelines and pipe networks in some oil transmission stations are complex with numerous branches, so the pipelines need to be segmented and taken out before cleaning operations can be carried out; At present, the high-pressure water jet cleaning technology is widely used in crude oil pipeline cleaning, which relies on the impact force of high-pressure water flow to strip and remove the fouling on the inner wall. However, most of the existing cleaning equipment focuses on the optimization of cleaning actuators such as the nozzle structure, but ignores the automation and integration of the cleaning process. In actual operation, the crude oil pipelines to be cleaned are bulky, and their loading, positioning and unloading processes after cleaning are often dependent on auxiliary equipment such as traveling cranes and slings with a large amount of manual operation. This mode of separating material handling and cleaning operations not only divides the entire cleaning process into multiple tedious and independent steps, reducing the operation efficiency, but also has great potential safety hazards in the pipeline hoisting and alignment links, making it difficult to realize fast and continuous automatic cleaning operations.

[0003] To this end, the utility model designs a self-rotating platform for crude oil pipeline cleaning, aiming at solving the deficiencies of the prior art. The platform can realize the automatic integration of the crude oil pipeline cleaning process, can conveniently carry out cleaning operations on the pipelines in the segmented cleaning scenario of complex pipe networks, and at the same time saves the amount of cleaning agent, improves the cleaning efficiency and operation safety, meets the environmental protection and pollution-free cleaning requirements, and provides an efficient solution for the cleaning links in the decommissioning disposal and maintenance of crude oil pipelines. Contents of the Utility Model

[0004] Aiming at the problems existing in the prior art that the crude oil pipeline cleaning platform has a tedious pipeline loading and unloading process, low automation degree, and independent functional units leading to a complex overall structure and low operation efficiency, the utility model aims to provide a self-rotating platform for crude oil pipeline cleaning with an improved structure, which can effectively solve the above problems.

[0005] The utility model provides a self-rotating platform for crude oil pipeline cleaning, which comprises a cleaning tank, and symmetrical platforms fixedly connected to the upper part of the cleaning tank, a semi-arc rotator is rotatably mounted on the symmetrical platforms, and a rotary gun is further fixedly mounted at one end of the symmetrical platforms; as well as a second vertical lifting track arranged parallel to one side of the symmetrical platforms, a first vertical lifting track arranged parallel to the other side of the symmetrical platforms, and automatic execution components respectively working on the tracks.

[0006] The automated execution components include a first thruster and a first lifter slidably connected to the second vertical rail, and a second thruster, a protective cover, and a second lifter slidably connected to the first vertical rail.

[0007] Furthermore, the first lifting device is located on the travel path of the first propeller, the second lifting device is located on the travel path of the second propeller, and the protective cover is fixedly connected to the second propeller. Through this integrated layout of the two side tracks, propulsion components and lifting components, the functions of pipeline feeding, lifting, positioning and removal are integrated on both sides of the platform, forming a highly coordinated overall structure with the cleaning mechanism in the central area.

[0008] Preferably, the rotary gun is mounted on a mounting base, and the mounting base is fixed to the symmetrical platform. The output end of the rotary gun is connected to a long-handled nozzle. This arrangement provides a stable mounting base for the long-handled nozzle, ensuring that it will not shake when it is inserted into the pipe for high-speed rotating cleaning, thus guaranteeing the stability and accuracy of the cleaning.

[0009] Preferably, the first lifting device has a bearing surface with a guide slope facing the cleaning tank. The shape design of the bearing surface can not only stably support the cylindrical pipe body and prevent it from rolling during movement and lifting, but its own guide slope can also cleverly guide the sewage back to the cleaning tank below during the cleaning process, realizing the integration of support and guide functions.

[0010] Preferably, one end of the first thruster can abut against one end of the first lifter. This non-rigid abutment connection structure is simple and reliable, allowing the first thruster to apply linear thrust to the first lifter when needed, and the two can be separated when not needed, simplifying the control logic and mechanical structure.

[0011] Preferably, one end of the second thruster is fixedly connected to the protective cover, and the other end of the second thruster can abut against the second lifting device, so that a single second thruster has dual functions. In the loading process, the protective cover to which it is fixedly connected is used to axially push the pipe for positioning, while in the unloading process, its other end is converted to push the second lifting device. A single drive source realizes the driving of different components at different stages, optimizing the spatial layout and cost.

[0012] Preferably, the bearing center of the semi-arc rotator is coaxial with the central axis of the long rod nozzle. This precise coaxial layout is the key to achieving high-quality cleaning. It ensures that when the pipe body rotates, the inner wall of the pipe and the rotating long rod nozzle always maintain a uniform distance, avoiding uneven cleaning or equipment collision caused by eccentricity.

[0013] Preferably, the semi-arc rotator includes a first drive mechanism, and the rotating gun includes a second drive mechanism, which drives the long-rod nozzle to rotate. By controlling the revolution of the pipe body and the rotation of the nozzle through two independent drive mechanisms, a compound dual-rotation cleaning motion is achieved, improving cleaning efficiency and coverage.

[0014] Preferably, the bearing arc surface of the semi-arc rotator and the outer periphery of the long rod nozzle form an annular space for accommodating the pipe body. This feature clearly defines the working area of ​​the pipe body structurally, further ensuring the relative positional relationship of each moving part when working together, thus forming a stable and efficient cleaning operation space.

[0015] This utility model has the following beneficial effects: 1. This utility model, by setting a first vertical lift track and a second vertical lift track on both sides of a symmetrical platform, and a first pusher, a first lifter, a second pusher, and a second lifter that slide and cooperate on the tracks, solves the problems of high labor intensity, low positioning accuracy, and low overall automation of crude oil pipelines due to reliance on manual or semi-automatic equipment for loading and unloading. It achieves the technical effect of fully automatic loading, precise positioning, and automatic unloading of pipelines, improving production efficiency and reducing labor costs.

[0016] 2. This utility model, by setting a semi-arc rotator that can drive the pipe body to rotate, and cooperating with a long rod nozzle that rotates inside the pipe, solves the problem in the prior art that it is difficult to achieve full coverage cleaning of the inner wall by rotating a single nozzle or moving the pipe in one direction, resulting in cleaning dead corners. It achieves a dual rotation cleaning effect by working in synergy between the rotation of the pipe body and the rotation of the nozzle, ensuring comprehensive cleaning of the inner wall of the pipe without dead corners, and improving the cleaning quality.

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.

[0020] Please refer to Figures 1 to 4 This utility model provides a self-rotating platform for cleaning crude oil pipelines, which aims to solve the problems of low automation in loading and unloading crude oil pipelines, complex cleaning and positioning structures, and cumbersome unloading processes in the prior art.

[0021] like Figure 1 As shown, the crude oil pipeline cleaning self-rotating platform includes a cleaning tank 1 and a symmetrical platform 2 fixedly connected to the upper part of the cleaning tank 1. The cleaning tank 1 forms the bottom base of the entire platform, and the symmetrical platform 2 serves as the core bearing platform. A semi-arc rotator 3 is rotatably installed on the symmetrical platform 2, and a rotating gun 6 is fixedly installed at one end of the symmetrical platform 2. A second vertical rail 5 is arranged parallel to one side of the symmetrical platform 2, and a first vertical rail 4 is arranged parallel to the other side of the symmetrical platform 2. This structural layout constitutes the overall framework for cleaning and material conveying.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 The rotating gun 6 is mounted on the mounting base 7, which is fixed to the symmetrical platform 2. The output end of the rotating gun 6 is connected to the long rod nozzle 14. The bearing center of the semi-arc rotator 3 is coaxial with the central axis of the long rod nozzle 14, and the bearing arc surface of the semi-arc rotator 3 and the outer periphery of the long rod nozzle 14 form an annular space for accommodating the pipe body 8.

[0023] Please refer to Figure 1 and Figure 4A first pusher 9 is slidably connected to the second vertical track 5, and a first lifting device 10 is also slidably connected to the second vertical track 5. A second pusher 12 is slidably connected to the first vertical track 4, and a second lifting device 13 is also slidably connected to the first vertical track 4. A protective cover 11 is fixedly connected to the second pusher 12. This set of tracks and the slider system constitute an automated material flow mechanism. Specifically, the first lifting device 10 is set on the stroke path of the first pusher 9, and one end of the first pusher 9 can abut against one end of the first lifting device 10, so that the first pusher 9 can push the first lifting device 10 to move along the second vertical track 5. Similarly, the second lifting device 13 is set on the stroke path of the second pusher 12, one end of the second pusher 12 is fixedly connected to the protective cover 11, and the other end of the second pusher 12 can abut against the second lifting device 13, so that the second pusher 12 can push the protective cover 11 or the second lifting device 13 to move along the first vertical track 4.

[0024] The rotating gun 6 is fixed to the symmetrical platform 2 by the mounting base 7. The output end of the rotating gun 6 is connected to the long rod nozzle 14. The long rod nozzle 14 is slender and extends into the interior of the pipe body 8. At least two sets of semi-arc rotators 3 are provided. The two sets of semi-arc rotators 3 are arranged at intervals along the axial direction of the long rod nozzle 14. The bearing arc surface of the semi-arc rotator 3 is used to support the outer wall of the pipe body 8. The bearing center of the semi-arc rotator 3 is coaxial with the central axis of the long rod nozzle 14. This coaxial structure ensures that the pipe body 8 can move stably around the long rod nozzle 14 when it is driven to rotate by the semi-arc rotator 3.

[0025] The first lifter 10 has a bearing surface with a guide slope facing the cleaning tank 1. The first lifter 10 is slidably connected to the second vertical rail 5. At the same time, the first pusher 9 is correspondingly slidably connected to the second vertical rail 5. One end of the first pusher 9 can abut against one end of the first lifter 10. In the assembled state, the reciprocating motion of the first pusher 9 realizes unidirectional pushing of the first lifter 10.

[0026] On the other side of the symmetrical platform 2, the second thruster 12 is slidably connected to the first vertical rail 4, and the protective cover 11 is fixedly connected to one end of the second thruster 12. The shape of the protective cover 11 is adapted to the end of the pipe body 8. At the same time, the second lifter 13 is correspondingly slidably connected to the first vertical rail 4. The second lifter 13 is set on the stroke path of the second thruster 12, and the other end of the second thruster 12 can abut against the second lifter 13. This segmented abutment structure ensures that the second thruster 12 can push the protective cover 11 or the second lifter 13 at different stroke stages.

[0027] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, please refer to Figure 2 and Figure 3 In order to achieve effective cleaning inside the pipe, the rotating gun 6 is fixed on the symmetrical platform 2 by the mounting base 7, and the long rod nozzle 14 is fixedly connected to the output end of the rotating gun 6. The rotating gun 6 is equipped with a second drive mechanism, which is used to drive the long rod nozzle 14 to rotate.

[0028] As another preferred embodiment, please refer to Figure 1 and Figure 3 In order to achieve synchronous rotation of the pipe body 8, a first driving mechanism is provided inside the semi-arc rotator 3. The first driving mechanism is used to drive the semi-arc rotator 3 to rotate, thereby driving the pipe body 8 it carries to rotate.

[0029] For a further preferred embodiment of the above-mentioned cleaning and rotating structure, please refer to... Figure 3 The bearing center of the semi-arc rotator 3 and the central axis of the long rod nozzle 14 are set to be coaxial. Furthermore, an annular space for accommodating the pipe body 8 is formed between the bearing arc surface of the semi-arc rotator 3 and the outer periphery of the long rod nozzle 14. This coaxially set annular space ensures that the pipe body 8 maintains a stable distance from the long rod nozzle 14 when rotating.

[0030] As another preferred embodiment, please refer to Figure 4 In order to effectively recover wastewater while lifting the main pipe body 8, the first lifter 10 has a bearing surface, the bottom of which has a guide slope facing the cleaning tank 1, and the cleaning wastewater can flow back into the cleaning tank 1 along the slope.

[0031] As another preferred embodiment, please refer to Figure 4 In order to achieve precise pushing of the first lifter 10, one end of the first pusher 9 can abut against one end of the first lifter 10. When the first pusher 9 slides on the second vertical track 5, it pushes the first lifter 10 to move through the abutment structure.

[0032] As another preferred embodiment, please refer to Figure 1 In order to switch between loading and unloading processes, one end of the second thruster 12 is fixedly connected to the shield 11 to push the shield 11 during loading, while the other end of the second thruster 12 can abut against the second lifter 13 to push the second lifter 13 during unloading. This structure realizes the driving of two different processes through a single propulsion component.

[0033] Working principle: In the loading process, the pipe body 8 is placed on the bearing surface of the first lifter 10. The first pusher 9 moves along the second vertical track 5. One end of the first pusher 9 can abut against the first lifter 10, pushing the first lifter 10 to move above the semi-arc rotator 3. The first lifter 10 descends and places the pipe body 8 on the semi-arc rotator 3. Subsequently, the second pusher 12 moves along the first vertical track 4, pushing the fixedly connected cover 11. The cover 11 pushes the pipe body 8 to move axially along the semi-arc rotator 3 until the long rod nozzle 14 connected to the rotating gun 6 on the mounting base 7 extends into the interior of the pipe body 8. During the cleaning process, the first drive mechanism drives the semi-arc rotator 3 to rotate, causing the pipe body 8 to rotate around its axis. At the same time, the second drive mechanism inside the rotating gun 6 drives the long rod nozzle 14 to rotate inside the pipe body 8. The cleaning wastewater flows out from the pipe body 8 and falls onto the bearing surface of the first lifter 10, which is located below the pipe body 8, and flows back to the cleaning tank 1 at the bottom via the guide slope on the bearing surface. During the unloading process, after cleaning, the first lifter 10 lifts the pipe body 8 again, causing it to separate from the semi-arc rotator 3. The second pusher 12 moves along the first vertical track 4 until its other end can abut against the second lifter 13, and pushes the second lifter 13 to move below the pipe body 8. The first lifter 10 descends and places the pipe body 8 on the second lifter 13. Finally, the second lifter 13 moves the pipe body 8 out of the symmetrical platform 2. Through the coordinated action of the first thruster 9, the first lifter 10, the second thruster 12, the protective cover 11, the second lifter 13, and the first and second vertical rails 4 and 5, this utility model realizes the automatic loading and unloading and precise positioning of the pipeline body 8. In conjunction with the dual rotation structure of the semi-arc rotator 3 and the long rod nozzle 14, as well as the sewage guiding structure of the first lifter 10, it solves the problems of low automation of crude oil pipeline loading and unloading, complex cleaning and positioning structure and cumbersome unloading process in the prior art.
