[0001] This utility model belongs to the field of pipeline sinking technology, and in particular relates to a pipeline sinking device for oil and gas pipeline laying construction. Background Technology

[0002] In oil and gas pipeline construction, pipeline sinking is a crucial step. Its purpose is to bury the pipeline to the designed depth to protect it from external damage and ensure the stability and safety of pipeline operation. Traditional pipeline sinking methods mainly include manual excavation, mechanical excavation, and hydraulic sinking.

[0003] However, existing pipe sinking devices cannot clamp and sink pipes of different specifications, resulting in poor practicality and requiring improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a pipeline sinking device for oil and gas pipeline laying construction. Through the driving force of the motor, the threaded rod, threaded sleeve, connecting block, clamping plate, hollow block, connecting spring, clamping block and other components work together to start the motor that runs through the side of the hollow plate, thereby driving the threaded rod fixed at the end of the output shaft to rotate. The rotation of the threaded rod drives the two threaded sleeves on the threaded connection circumference, thus solving the existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a pipeline sinking device for oil and gas pipeline laying construction, including a base and a body. The body is equipped with a mechanical arm, and the bottom of the mechanical arm is equipped with an adaptable clamping mechanism.

[0007] The adaptable clamping mechanism includes a hollow plate, which is fixedly connected to the bottom of the robotic arm. A motor passes through the side of the hollow plate, and a threaded rod is fixedly connected to the end of the output shaft of the motor. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod, and a connecting block is fixedly connected to the bottom of the threaded sleeve. A clamping plate is fixedly connected to the bottom of the connecting block.

[0008] Furthermore, horizontal hollow blocks are welded and fixed to the side of the clamping plate in an array. A connecting spring is welded and fixed to the innermost sidewall of the hollow block. A clamping block is welded and fixed to the end of the connecting spring away from the hollow block. The above design is beneficial for clamping pipes of different specifications.

[0009] Furthermore, the clamping block is slidably connected to the inner wall of the hollow block, and the side cross-section of the hollow plate is set as U-shaped. The design of the clamping block is conducive to effectively clamping the pipe.

[0010] Furthermore, the side section of the clamping plate is configured as an anti-detachment mechanism, which includes a rectangular plate. The rectangular plate is horizontally welded and fixedly connected to the side of the clamping plate. A fixing plate is fixedly connected to the top of the rectangular plate. A rotating shaft is rotatably connected to the inner side wall of the fixing plate. A support plate is fixedly connected to the circumferential surface of the rotating shaft. The above design helps to prevent the pipe from falling off during the clamping process.

[0011] Furthermore, a reset spring is fixedly connected to the bottom of the support plate, and the end of the reset spring away from the support plate is fixedly connected to the bottom of the rectangular plate. The design of the reset spring is conducive to driving the support plate to reset.

[0012] Furthermore, the side cross-section of the support plate is set to a rhombus shape, and the top of the support plate and the rectangular plate are both rhomboid. The rhombus shape of the side cross-section of the support plate is beneficial for fitting the circumferential surface of the pipe.

[0013] This utility model has the following beneficial effects:

[0014] This invention utilizes the driving force of a motor to activate components such as a threaded rod, threaded sleeve, connecting block, clamping plate, hollow block, connecting spring, and clamping block. This enables the motor, which runs through the side of the hollow plate, to rotate, thereby rotating the threaded rod fixed at the end of the output shaft. The rotation of the threaded rod causes the two threaded sleeves on the threaded connection circumference to slide linearly along the inner wall of the hollow plate. Simultaneously, it drives the connecting block fixed at the bottom of the two threaded sleeves to move. During the process of lowering the pipe, pipes of different specifications can be clamped.

[0015] This invention utilizes the rotational force of the rotating shaft to drive the rectangular plate, fixed plate, support plate, and return spring to work together. This enables the clamping plate to move when it moves, which in turn moves the rectangular plate fixed to the side. The movement of the rectangular plate, which in turn moves the support plate fixed to the circumference of the rotating shaft, thus contacting the circumference of the pipe. As the support plate continues to move, it prevents the pipe from detaching during the clamping process.

Detailed Implementation

[0024] Example

[0025] A pipeline sinking device for oil and gas pipeline laying construction includes a base 1 and a body 2. The body 2 is equipped with a mechanical arm 3, and the bottom of the mechanical arm 3 is equipped with an adaptable clamping mechanism 4.

[0026] The adaptable clamping mechanism 4 includes a hollow plate 41 with a U-shaped side cross-section. The hollow plate 41 is welded and fixedly connected to the bottom of the robotic arm 3. A motor 42 passes through the side of the hollow plate 41, and a threaded rod 43 is fixedly connected to the end of the output shaft of the motor 42. The threaded rod 43 is installed inside the hollow plate 41 through a bearing. The middle of the threaded rod 43 is provided with a forward thread and a reverse thread. Two sets of threaded sleeves 44 are threadedly connected to the circumferential surface of the threaded rod 43. One set of threaded sleeves 44 is threadedly installed on the forward thread, and the other set of threaded sleeves 44 is threadedly installed on the reverse thread.

[0027] When the motor 42 rotates, it drives the threaded rod 43 to rotate. When the threaded rod 43 rotates, its own forward and reverse threads drive the two sets of threaded sleeves 44 to move in opposite directions or in reverse.

[0028] Two sets of threaded sleeves 44 are fixedly connected to the bottom of a connecting block 45, and a clamping plate 46 is fixedly connected to the bottom of the connecting block 45. In order to improve strength, the threaded sleeves 44, connecting blocks 45 and clamping plates 46 are all made of steel, and the connection between them is welded.

[0029] Horizontal hollow blocks 47 are welded and fixed in an array on the side of the clamping plate 46. A connecting spring 48 is welded and fixedly connected to the innermost sidewall of the hollow block 47, and the connecting spring 48 will not fall out of the hollow block 47. A clamping block 49 is welded and fixedly connected to the end of the connecting spring 48 away from the hollow block 47, and the clamping block 49 will not fall out of the hollow block 47. The clamping block 49 is slidably connected to the inner wall of the hollow block 47, that is, the clamping block 49 can move back and forth in the hollow block 47 by compressing the connecting spring 48. The above design is beneficial for clamping pipes of different specifications.

[0030] To improve strength, the hollow block 47, the connecting spring 48, and the clamping block 49 are all made of steel, and the connection between them is welded.

[0031] A specific application of this embodiment is as follows: When clamping is required during pipeline laying, the worker places the pipeline between the clamping blocks 49. Then, the worker starts the motor 42 that runs through the side of the hollow plate 41, thereby driving the threaded rod 43 fixed at the end of the output shaft to rotate. The rotation of the threaded rod 43 drives the two threaded sleeves 44 connected to the circumferential surface to slide linearly on the inner wall of the hollow plate 41. At the same time, it drives the connecting block 45 fixed at the bottom of the two threaded sleeves 44 to move. When the connecting block 45 moves, it drives the two clamping plates 46 fixed at the bottom to move closer to each other. At the same time, it drives the multiple hollow blocks 47 fixed on the side to move. When the hollow block 47 moves, it drives the clamping block 49 sliding on the inner wall to contact the circumferential surface of the pipeline. As the threaded sleeves 44 continue to move, the clamping block 49 squeezes the pipeline. At the same time, the clamping block 49 is subjected to the reaction force of the pipeline, thereby keeping the connecting spring 48 fixed on the side of the clamping block 49 in a taut state. At this time, clamping can be performed according to the specifications of the pipeline.

[0032] Example

[0033] The side section of the clamping plate 46 is configured as an anti-detachment mechanism 5. The anti-detachment mechanism 5 includes a rectangular plate 51, which is horizontally welded and fixedly connected to the side of the clamping plate 46. A fixing plate 52 is fixedly connected to the top of the rectangular plate 51. A rotating shaft 53 is rotatably connected to the inner side wall of the fixing plate 52. A support plate 54 is fixedly connected to the circumferential surface of the rotating shaft 53.

[0034] The support plate 54 has a concave groove at its center, which directly engages with the circumferential surface of the rotating shaft 53, and the support plate 54 can rotate along the rotating shaft 53.

[0035] In order to ensure that the support plate 54 has a reset function, a reset spring 55 is fixedly connected to the bottom of the support plate 54, and the end of the reset spring 55 away from the support plate 54 is fixedly connected to the bottom of the rectangular plate 51. The design of the reset spring 55 is conducive to driving the support plate 54 to reset.

[0036] The side section of the support plate 54 is set as rhombus. The support plate 54 and the top of the rectangular plate 51 are both rhombus-shaped. The side section of the support plate 54 is set as rhombus, which is conducive to fitting the circumferential surface of the pipe.

[0037] The overall design of the aforementioned anti-detachment mechanism 5 helps to prevent the pipe from falling off during the clamping process.

[0038] A specific application of this embodiment is as follows: when the clamping block 49 clamps the pipe, when the clamping plate 46 moves, it drives the rectangular plate 51 fixed on the side to move. The support plate 54 fixed on the circumferential surface of the rotating shaft 53 moves, thereby contacting the circumferential surface of the pipe. As the support plate 54 continues to move, the pipe moves on the top of the support plate 54. When the pipe moves to a certain position, the rotating shaft 53 rotates, thereby driving the support plate 54 to move upward in an arc. At the same time, the return spring 55 fixed at the bottom of the support plate 54 is pressed into a taut state to prevent the pipe from falling off.
