Description

Technical Field

[0002] During the pipeline construction process, it is necessary to use a pipeline construction lifting device to lift the pipeline. The existing pipeline construction lifting device is usually composed of a lifting frame, a steel cable and a scissor clamp. The scissor clamp is generally provided in two groups, and the two groups of scissor clamps are installed under the lifting frame. When lifting the pipeline, the two groups of scissor clamps are used to clamp the pipeline, and then the crane lifts the lifting frame through the steel cable to realize the lifting operation of the pipeline.

[0003] The existing application number is: CN202222359885.7. The utility model relates to the technical field of gas pipeline hoisting equipment, and in particular to a gas pipeline hoisting construction device, including a positioning base plate, the upper surface of the positioning base plate is fixedly connected to a positioning frame, one side of the positioning frame is fixedly connected to a driving motor, the internal rotation of the positioning frame is connected to a winding disk, the upper surface of the positioning base plate is located on one side of the positioning frame and is fixedly connected to a vertical rod, the upper end of the vertical rod is fixedly connected to a horizontal plate, and a reinforcement plate is fixedly connected between the horizontal plate and the vertical rod; the utility model quickly adjusts the position of the adjusting slider by manual sliding according to the length of the gas pipe, so that the positioning pin drives the anti-skid plate to rotate synchronously, and then the anti-skid plate is fitted with the mounting plate, and then the position of the adjusting slider is self-locked by the anti-skid plate, thereby helping the equipment to reasonably grasp gas pipes of different lengths, thereby achieving the effect of improving the scope of use of the equipment and reasonable grasping.

[0004] Based on the above, when laying pipelines in large quantities and flange connections are used between pipelines, the flanges of the two sets of connected pipelines need to be connected by bolts. Therefore, the threaded holes on the flanges connecting the two sets of pipelines need to be completely aligned before installation and connection can be performed. When using the existing pipeline construction hoisting device to lay pipelines, when the flange pipeline being hoisted is attached to the end face of the flange pipeline that has been laid, the threaded holes on the flanges connecting the two sets of pipelines are often not completely aligned. At this time, workers are required to slightly rotate the flange pipeline being hoisted in order to completely align the threaded holes on the flanges connecting the two sets of pipelines. When the diameter of the pipeline used in the construction is large and the weight is heavy, it is difficult and laborious for manpower to slightly rotate the pipeline, which affects the efficiency of pipeline installation.
