Description

Technical Field

[0001] The utility model relates to the technical field of oil pipeline installation, in particular to an oil pipeline installation device. Background Art

[0002] The oil pipeline is one of the main equipment in the oil storage and transportation industry, and is also the most important transportation equipment for crude oil and petroleum products. Compared with railway and road oil transportation, which are also land transportation methods, pipeline oil transportation has the characteristics of large transportation volume, good airtightness, low cost and high safety factor. When installing the oil pipeline in the prior art, a crane and a lifting rope are usually used for lifting and installation, and the lifting rope needs to be connected manually, which not only has low operating efficiency but also has safety hazards. For example, the publication number CN105836603 A Chinese patent document discloses an oil pipeline installation device, which includes a base, a suspension rod, a suspension rope, two protection pads, and a crane. The protection pad with a cylinder is installed on the left and right ends of the oil pipeline and locked with a wire rope with a lock buckle. The suspension rod is passed through the oil pipeline through the circular hole and the cylinder of the protection pad, and the suspension rope is used to connect the circular rings at both ends of the suspension rod to achieve lifting. However, it has the following shortcomings in actual operation: although the damage caused by the suspension rope contacting and rubbing the inner wall of the oil pipeline and the ports at both ends is avoided, because the suspension rod is connected by threads with two left and right sub-rods, after multiple uses, the two sub-rods are damaged due to the force of the threads and cannot be adjusted for continued use. The cylinder of the protection pad is only provided with a spring column in one diameter direction. The lifting process often causes uneven force and deformation at the ends of the oil pipeline, which still makes it difficult to connect the oil pipeline. The operations of lifting the two ends of the oil pipeline in turn and installing the protection pads, passing the suspension rod through the protection pad and the oil pipeline, etc. still require manual operations by operators, which is not only time-consuming and labor-intensive, but also has low work efficiency and safety hazards. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide an oil pipeline installation device, which overcomes the shortcomings of the above-mentioned prior art and can effectively solve the problems that the existing use of cranes and lifting ropes to install oil pipelines easily causes uneven force on the pipeline ends and deformation, and the installation of lifting devices requires manual operation, is time-consuming and labor-intensive, has low work efficiency, and has potential safety hazards.

This can effectively avoid damage to the oil pipeline caused by uneven force on the lifting rope or the lifting rod, and avoid the process of manually installing the protective pads, lifting rods and lifting rope locks at both ends, which not only saves manpower and time costs, but also significantly reduces the safety hazards of related operations.

[0007] 2. The rotary drive device can achieve precise rotation during lifting, solving the problem of inconvenient angle adjustment during installation and docking. Automatic control can improve the stability and accuracy of the operation, while greatly improving the efficiency of the installation work and the progress of the operation.
