Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to oil field pipeline hoisting equipment. Background Art

[0002] Oilfield pipelines are mainly used to transport fluid materials such as oil and natural gas to ensure that these resources can be safely and efficiently transferred from one location to another. In the installation process of oilfield pipelines, lifting equipment such as cranes, cranes and hoists play a key role. They can quickly and accurately lift heavy pipelines and equipment to the designated location, greatly improving the efficiency of the operation, shortening the construction period, and ensuring the safety of the operation. In the related technology, the hook of the crane is connected to the connecting belt or clamps used to connect the oilfield pipeline. Subsequently, the crane realizes the lifting of the oilfield pipeline by accurately adjusting the lifting rope. In the process of using the connecting belt and the hook for connection, if a conventional hook is used, it is very easy to cause safety hazards in actual operation because it is not equipped with an effective anti-slip design, which significantly increases the risk of accidental detachment of the connecting belt; and the connecting belt also faces many inconveniences when adapting to oilfield pipelines of different diameters. Due to the lack of flexibility in its structural design, it is difficult to make quick and accurate adjustments according to changes in the diameter of the pipeline. This results in operators often needing to spend a lot of time and energy to manually adjust the size or position of the connecting belt when facing the diverse specifications of oil field pipelines, which not only reduces work efficiency, but also makes it difficult to ensure the stability of each connection, bringing many obstacles to the entire lifting operation process. Therefore, those skilled in the art provide an oil field pipeline lifting device to solve the problems raised in the above background technology. Utility Model Content

Simply start the device to allow the system to quickly enter the optimal working state. In this way, the operation preparation cycle is greatly shortened, and the operator can devote himself to the lifting operation at the fastest speed, effectively avoiding the unnecessary waste of time and comprehensively and substantially improving the overall work efficiency.

[0026] A crane 1 is provided with a boom 2, the boom 2 is connected to a lifting rope 3, the lifting rope 3 is connected to a connecting belt 4 through a connecting mechanism, the connecting belt 4 is in contact with and connected to an oilfield pipeline, and the crane 1 can perform lifting operations on the oilfield pipeline;

[0027] The connecting mechanism includes a pulley 7, a connecting frame 5 and a support plate 6. The connecting frame 5 is connected to the suspension rope 3 through the pulley 7. The support plate 6 and the connecting frame 5 are connected through a composite fastening assembly. The composite fastening assembly includes a connecting block 13 and a fixing rod 14.

During equipment maintenance and overhaul, the operator can use the convenient operating characteristics of the assembly components to quickly complete the disassembly and installation of the connecting belt 4, greatly reducing the maintenance time and effectively improving the maintenance efficiency.

[0029] An assembly component for clamping one end of the connecting belt 4 is provided on the supporting plate 6, and the assembly component includes a first clamping plate 18 and a second clamping plate 19. The first clamping plate 18 is fixedly connected to the supporting plate 6, and the first clamping plate 18 and the second clamping plate 19 are connected by a first mounting bolt 20, and one end of the connecting belt 4 is clamped between the first clamping plate 18 and the second clamping plate 19, and limiting plates 21 are fixedly provided on both sides of the first clamping plate 18, and the second clamping plate 19 is clamped between the limiting plates 21;

[0030] When connecting one end of the connecting belt 4 to the supporting plate 6, one end of the connecting belt 4 is placed between the first clamping plate 18 and the second clamping plate 19, and then the first mounting bolt 20 is used to fix the first clamping plate 18 and the second clamping plate 19, so that one end of the connecting belt 4 can be clamped and fixed between the first clamping plate 18 and the second clamping plate 19, wherein the second clamping plate 19 can be quickly aligned with the first clamping plate 18 by setting the limiting plate 21, thereby improving the connection efficiency;

The switch 12 on the support plate 6 can be pressed to control the start of the servo motor 11. The servo motor 11 drives the winding roller 10 to rotate through the rotating rod 9. The winding roller 10 can wind up the connecting belt 4, thereby adjusting the length of the connecting belt 4. Facing oilfield pipelines of different diameters, it can flexibly adjust the stretching degree of the connecting belt 4 according to the size of the pipe diameter, so that the connecting belt 4 can be closely connected to the outside of the oilfield pipeline, accurately adapting to various operational needs. In this way, there is no need to spend extra time on tedious adjustments, and operators can quickly get to work, which greatly shortens the operation preparation cycle, thereby improving work efficiency in all aspects and providing strong guarantees for the lifting operation of oilfield pipelines. When performing the separation operation of the oilfield pipeline and the connecting belt 4, first, the crane 1 places the oilfield pipeline steadily in the designated operation area; then, the servo motor 11 is started, and the servo motor 11 slowly lengthens the connecting belt 4 originally wound thereon at a preset speed through the rotating rod 9 and the winding roller 10, so that the connecting belt 4 gradually loosens and reduces the restraining force on the oilfield pipeline. After the connecting belt 4 is relaxed to a certain extent, the operator can remove the connecting belt 4 from both ends of the oilfield pipeline, and successfully complete the separation operation of the oilfield pipeline and the connecting belt 4;
