Description

Technical Field

[0001] This utility model relates to the field of hoisting, and in particular to an auxiliary hoisting tool for large pipeline compensators. Background Technology

[0002] In industrial sectors such as energy, chemical, and metallurgy, as well as in large-scale municipal engineering projects, large pipeline systems undertake the crucial task of transporting high-temperature, high-pressure, or corrosive media over long distances and at high flow rates. Large pipeline compensators, as key flexible connection components in pipeline systems, effectively absorb displacement caused by factors such as temperature changes, mechanical vibration, and terrain settlement, ensuring the safe and stable operation of the pipeline system. Due to the large size and weight of large pipeline compensators, the safety and reliability of their hoisting process are paramount to the entire pipeline project. Currently, there are two main methods for hoisting large pipeline compensators: directly hooking the bolt holes with a hook and hoisting by passing a conveyor belt through the compensator.

[0003] The lifting method of directly hooking the hook into the bolt holes results in extremely high local stress when the hook contacts the flange of the large pipeline compensator due to its large weight. During lifting, moving, and positioning, this high stress can easily cause severe mechanical damage to the flange surface, leading to scratches and deformation on the flange sealing surface, thus affecting the sealing performance and structural strength of the compensator. Furthermore, this lifting method makes it difficult to control the center of gravity of the pipeline compensator, resulting in poor lifting stability. It is prone to tilting during transport, and there is even a risk of the hook slipping out of the bolt holes, which could not only damage the compensator but also potentially cause a major safety accident, seriously threatening the safety of construction personnel and the progress of the project.

[0004] When hoisting a large pipeline compensator using a cable harness, the irregular shape and weight of the compensator require significant time and effort from construction workers. They must repeatedly adjust the cable harness's winding method and position to find a suitable balance point and ensure stability during hoisting. Even so, it's difficult to completely prevent the compensator from swaying or twisting during hoisting, leading to a substantial reduction in installation efficiency. Furthermore, frequent adjustments to the cable harness increase rope wear, further impacting hoisting safety and construction costs.

[0005] In summary, the two existing methods for hoisting large pipeline compensators have problems such as high risk of mechanical damage, poor hoisting stability, and low installation efficiency in practical engineering applications, and can no longer meet the requirements of high-quality and high-efficiency construction for modern large-scale pipeline projects.

[0006] Therefore, there is an urgent need to develop an auxiliary hoisting tool for large pipeline compensators. This tool adopts an integrated support structure to avoid direct contact with the weak parts of the pipeline compensator, distributing the stress points to the flanges and reinforcing rings. It also features a modular design to adapt to pipeline compensators of different diameters and can be stored separately for easy transportation. Compared with traditional hoisting methods, this tool reduces rework and spare parts waste caused by hoisting damage, shortens the construction period, and is especially suitable for emergency repair scenarios. It solves industry pain points and combines protection, efficiency, and economy. Utility Model Content

At the same time, it adopts a modular design to adapt to pipeline compensators of different diameters, and can be stored separately for easy transportation.

[0008] This utility model discloses an auxiliary hoisting tool for large pipeline compensators, including a base and a clamping assembly. The clamping assembly includes two jaws that are adjustable in relative position and lockable on the base. The clamping constraint or release of the pipeline compensator is achieved by adjusting the relative position between the two jaws.

[0009] Furthermore, the base is provided with a number of mounting adjustment holes, and the two grippers are mounted on the base through the mounting adjustment holes, and the adjustable relative position is achieved by mounting them in different mounting adjustment holes.

[0010] Furthermore, the mounting adjustment holes are arranged in an array at the positions on the base where the grippers are mounted, and the two grippers are respectively mounted on the base through the corresponding mounting adjustment holes.

[0011] Furthermore, the clamping components are at least two sets and arranged along the length of the pipe compensator.

[0012] Furthermore, the gripper has an adjustable gripping plate on its gripping surface for fine-tuning the gripping constraint on the pipeline compensator.

[0013] Furthermore, the clamping surface of the clamping plate is an arc surface that conforms to the clamping position of the pipe compensator, and the arc surface is provided with a gasket to prevent the pipe compensator from sliding.

[0014] Furthermore, the gripper includes a mounting base plate and a clamping support plate perpendicular to the mounting base plate. An inclined brace is provided between the mounting base plate and the clamping support plate. The clamping plate is arranged on the clamping support plate with its back side parallel to the clamping support plate.

[0015] Furthermore, it also includes an adjustment component, which includes a screw that is threadedly engaged with the clamping support plate and has one end engaged with the clamping support plate in a single-degree-of-freedom rotational manner, while the other end forms a drive unit for finely adjusting the constraint of the clamping plate.

[0016] Furthermore, the clamping plate is provided with at least one guide limiting rod, and the clamping support plate is provided with a guide limiting hole for passing through the guide limiting rod and slidingly engaging.

[0017] Furthermore, the base is also provided with lifting lugs for cooperating with lifting equipment and support legs for supporting the base.
