Description

Technical Field

[0001] The utility model relates to the technical field of oil and natural gas drilling, in particular to a composite lifting mechanism. Background Art

[0002] Pipe strings are essential tools in oil and gas drilling. During the drilling process, they must be moved and transferred, requiring specific heights for transfer. For example, they must be moved from a storage height to a transfer height, and then from the transfer height to an operating height. With the advancement of oil and gas drilling, more and more mechanized equipment is being used in the process, with manipulators being a key component in transferring and transferring pipe strings.

[0003] Currently, patent publication number CN116241198A discloses a drill pipe assisted handling robot. The device includes a vertical guide rail column, which is fixed vertically on the guide rail base as part of the intelligent drilling platform; a robotic arm assembly that can move up and down along the vertical guide rail column and can be positioned at the top or bottom of the guide rail for automatic operation; and a mechanical gripper assembly for grabbing the drill pipe and, after lifting the drill pipe to a certain height and vertically, rotating the small roller on it to thread the drill pipe to or remove it from another section of drill pipe. Although it can replace manual pipe removal operations, it cannot adapt to the operation requirements of pipes of different sizes, weights, and positions, and cannot meet the requirements of precise changes in height position, which affects operational efficiency.

Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0034] like Figure 1 and Figure 2 As shown, this embodiment provides a composite lifting mechanism comprising a base 1, a column 2, a trolley 3, a drive assembly, and a transmission assembly. The column 2 is supported on the base 1, the trolley 3 is mounted on the column 2 so as to be movable up and down, the manipulator is mounted on the trolley 3, and the drive assembly is mounted on the base 1. The drive assembly is connected to the trolley 3 via a transmission assembly mounted on the column 2 to drive the trolley 3 to move up and down along the column 2. In this specific embodiment, a lubrication pump 11 for supplying lubricating oil is provided on the base 1.

[0035] Specifically, the manipulator is mounted on the mobile trolley 3. The driving assembly and the transmission assembly can be used to precisely position the moving speed and height of the mobile trolley 3, thereby achieving precise height adjustment of the manipulator to meet the requirements of operating pipes of different sizes, weights, and positions. This effectively improves the success rate when delicate operations such as precisely inserting a pipe into a wellhead or docking a casing are required. The column 2 is supported on the base 1, which improves the stability of the entire equipment and ensures the safe and stable operation of the mobile trolley 3 and the manipulator in high-load and high-vibration environments. Compared with existing technologies, this can meet the various position requirements and precision requirements of pipes of different specifications, improve the efficiency of pipe handover and transfer, and its higher stability can adapt to a variety of complex operating environments, ensuring operational safety and efficiency.

[0036] Furthermore, if Figure 3-Figure 6As shown, the column 2 is provided with two guide rails 21 extending along its length. The mobile trolley 3 is supported on the two guide rails 21 via two roller assemblies, one-to-one. A track plate extending along its length is provided on the inner side of the guide rail 21, and the roller assemblies are supported on the track plate. The track plate includes two first plates 22 and a second plate 23. The two first plates 22 are arranged in parallel, and the second plates 23 are connected to one side of the two first side plates. Each roller assembly includes two first support rollers 31 and two second support rollers 32. The two first support rollers 31 are connected to the two second support rollers 32 in a one-to-one manner to form two composite rollers. One side of the mobile trolley 3 is supported within one guide rail 21 via two composite rollers. The first support roller 31 is rollably supported on the first track plate, and the second support roller 32 is rollably supported on the second track plate. The first support roller 31 and the first track plate are used to resist overturning moments in the first direction, while the second rollers and the second track plate are used to resist overturning moments in the second direction.

[0037] Furthermore, if Figure 2-Figure 5 As shown, the transmission assembly includes a driving sprocket 41, a chain 42, and a driven sprocket 43. The driving sprocket 41 is rotatably mounted on the base 1, and the driven sprocket 43 is rotatably mounted on the top of the column 2. The driving sprocket 41 is connected to the driven sprocket 43 via the chain 42. The mobile trolley 3 is connected to the chain 42. The driving sprocket 41 is connected to the drive assembly to drive the driving sprocket 41 to rotate. The rotation of the driving sprocket 41 is converted into vertical movement of the mobile trolley 3 along the column 2 by the chain 42. By driving the driving sprocket 41 and the chain 42, the moving speed and height position of the mobile trolley 3 can be precisely determined. The drive assembly includes a driver 51 and a reducer 52. The driver 51 and the reducer 52 are mounted on the base 1. The driver 51 is connected to the driving sprocket 41 through the reducer 52 to drive the driving sprocket 41 to rotate. Concentrating the main power transmission on the base 1 prevents excessive vibration from being transmitted to the manipulator, reducing equipment wear and the probability of failure during operation, thereby ensuring operational safety.

[0038] Furthermore, if Figure 3 and Figure 5As shown, in this embodiment, the upper portion of the movable trolley 3 is connected to the chain 42 via a first connecting assembly, and the lower portion of the movable trolley 3 is connected to the chain 42 via a second connecting assembly. Specifically, the first connecting assembly includes a first connecting rod 331, a second connecting rod 332, a first pin 333, and a second pin 334. The first connecting rod 331 and the second connecting rod 332 are arranged parallel to the upper portion of the movable trolley 3. The first connecting rod 331 is rotatably connected to the chain 42 via the first pin 333, and the second connecting rod 332 is rotatably connected to the chain 42 via the second pin 334. Adjustment nuts are provided on the first connecting rod 331 and the second connecting rod 332 for adjusting the tension of the chain 42. Furthermore, spoke sensors are provided on the first connecting rod 331 and the second connecting rod 332 for accurately measuring the weight of the load on the chain 42. The second connecting assembly includes a third connecting rod 341, a connector 342, and a third pin 343. The third connecting rod 341 is rotatably connected to the connector 342 via the third pin 343, and the connector 342 is connected to the chain 42. The third connecting rod is provided with a disc spring that can adapt to changes in the tension of the chain 42 and prevent the chain 42 from jumping during use.

[0039] The usage of the composite lifting mechanism provided in this specific embodiment is that the starting driver 51 drives the driving sprocket 41 to rotate through the reducer 52, and the rotation of the driving sprocket 41 is converted into the vertical movement of the mobile cart 3 along the column 2 through the chain 42, thereby driving the vertical lifting of the manipulator installed on the mobile cart 3.
