Description

Technical Field

[0001] This utility model belongs to the field of electromechanical installation and pipeline hoisting technology, specifically a device for lifting pipelines using a vertical opening. Background Technology

[0002] During the construction and installation process, various objective factors often lead to situations where glass curtain walls are installed but mechanical and electrical pipelines are not yet complete. Using construction elevators for transport not only requires cutting the pipelines but also consumes a significant amount of manpower. In such cases, exploring methods to complete the installation of riser pipelines at the lowest possible cost is of paramount importance.

[0003] Existing pipe lifting devices primarily utilize winches and adjustable lifting arms to achieve stable pipe lifting. These devices are mainly used in basements or other locations requiring pipes to be raised to a certain height. Specifically, a winch lifts the lifting frame to the desired height. A motor drives a double-threaded rod to rotate, adjusting the spacing of the lifting arms to accommodate pipes of different lengths. The pipe is then placed on the lifting arms and secured with limiting sleeves and brackets to ensure stability. While this type of lifting device is relatively stable during lifting, it suffers from structural complexity and cumbersome operation. Utility Model Content

[0004] This invention overcomes the shortcomings of the prior art by proposing a device for lifting pipes using a vertical opening; it can achieve stable, fast, and easier-to-operate pipe lifting.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A device for lifting a pipe using a vertical opening includes a pipe-end support and clamping structure. The pipe-end support and clamping structure includes a main rod, a sliding column, a disc base, a top hook, and a clamping mechanism. The bottom of the main rod is fixedly connected to the center of the disc base. The sliding column is sleeved on the outside of the main rod, and multiple pairs of first connecting ears are evenly distributed on the bottom of the main rod, each pair being fixedly connected to the bottom of the main rod. Multiple second connecting ears are evenly arranged on the outer wall of the sliding column. One side of each second connecting ear is fixedly connected to the sliding column. The positions of the first and second connecting ears correspond. The clamping mechanism includes a first rotating arm and a second rotating arm. The second connecting ear is hinged to one end of the first rotating arm. The first connecting ear is also hinged to one end of the second rotating arm. The end of the second rotating arm away from the first connecting ear is located at the edge or outside of the disc base. The end of the second rotating arm away from the first connecting ear is used to clamp onto a groove on the inner wall of the pipe. The end of the first rotating arm away from the second connecting ear is hinged to the second rotating arm. The diameter of the disc base is larger than the diameter of the pipe, and a top hook is connected to the top of the main rod.

[0007] Furthermore, each second connecting lug is bolted to two first rotating arms; the two first rotating arms are symmetrically arranged on both sides of the second connecting lug.

[0008] Furthermore, the ends of both first rotating arms furthest from the second connecting lugs are bolted to the second rotating arms.

[0009] Furthermore, the second rotating arm has an inverted trapezoidal structure, with one side of the inverted trapezoidal second rotating arm being a trapezoidal hypotenuse and the other side being a vertical side; each pair of first connecting ears is hinged to the vertical side of a second rotating arm by bolts; the trapezoidal hypotenuse of the second rotating arm is located at the edge or outside of the disc base; the ends of both first rotating arms away from the second connecting ears are hinged to the ends of the trapezoidal hypotenuse of the second rotating arm by bolts.

[0010] Furthermore, the upper side wall of the main pole is provided with limit points to limit the sliding column.

[0011] Furthermore, the top of the main rod has a flat, round structure with an opening, through which the connecting bolt passes to connect with the U-shaped top hook.

[0012] Furthermore, it also includes a pipe top protection structure, which includes a conical cylinder with both the upper and lower bottoms of the conical cylinder being open structures, and the conical cylinder being detachably connected to the top of the pipe.

[0013] Furthermore, the conical cylinder is divided into two parts along its axis, with one side connected by a hinge and the other side being an open structure.

[0014] The beneficial effects of this utility model compared to the prior art are as follows:

[0015] This utility model utilizes a pipe-supporting clamping structure at the bottom of the pipe section for rapid positioning during pipe lifting. Installation is extremely convenient; the pipe can simply be placed on the circular base. It also provides greater stability during hoisting, and the overall structure is simple and easy to operate. The top protective structure safeguards the top of the pipe, making hoisting safer. Attached Figure Description
