Description

Technical Field

[0001] The present invention belongs to the technical field of fastening equipment, and more specifically, relates to a multi-layer, large-span pipe gallery adaptive pipe threading device and an operating method. Background Art

[0002] With the advancement of technology, the concept of integrated design has attracted much attention, which includes the compact and centralized layout of pipelines. As a result, the construction of multi-layer and large-span pipeline corridors is a difficult problem that needs to be overcome. Multi-layer and large-span pipeline corridors are embodied in various structural forms. In traditional process flows, pipes are either pulled by electric winches or by installing multiple pulley combinations to pass the pipes. Electric winches are suitable for pipeline corridors with large pipe-passing spaces, small spans, and a small number of floors. The disadvantages are also obvious. It requires a lot of manpower and time, is labor-intensive, and is difficult to construct in a small space. Pulley combination pipe delivery is suitable for various pipeline corridors, but the disadvantage is that a large number of pulley groups are required, which consumes a lot of manpower and time. At the same time, the pulley groups must be removed after the pipeline is lifted before it can be put into place, increasing the workload and safety risks.

[0003] In the prior art, patent CN119163808A: A pipe threader for pipe gallery, which avoids the wear and tear on the surface of the pipe caused by manual or hand-pulled winches, effectively ensures the quality of the pipe, facilitates the next step of construction, and also improves the efficiency of pipe threading. However, for multi-layer and large-span pipe galleries, a large number of pipe threaders are required, and the pipe threaders are connected to the pipes, which poses a hidden danger when removing the pipe threaders. The pipes must be removed before they can be put into place. In the prior art, patent CN206478312U: A pipe threader for pipe gallery pipes, which avoids the wear and tear on the surface of the pipe caused by manual or hand-pulled winches, and prevents the lateral movement of the pipes. However, for pipe threading operations of pipes of different specifications, the inclination angle of the two pulleys needs to be adjusted, which is cumbersome and difficult to operate. In the prior art, patent CN218818583U: A pipe threading device for a pipe gallery, by providing a protective layer of polytetrafluoroethylene material on each of the three rollers, can reduce the friction between the pipe and the roller, and reduce the damage of the roller to the anti-corrosion layer of the pipe. However, for multi-layer and large-span pipe galleries, a large number of pipe threaders are required, and the pipe threaders are connected to the pipes. There are hidden dangers in removing the pipe threaders, and the pipes must be removed before they can be put into place.

[0004] Therefore, at this stage, there is an urgent need for a multi-layer large-span pipe corridor pipe threading device, which can solve the problem that a large number of pipe threaders need to be set up for large-span pipe corridors in the traditional method to achieve the pipe threading work of large-span pipe corridors, thereby effectively reducing construction steps, reducing labor losses, speeding up construction progress, and improving construction quality and safety.

[0058] The adaptive pipe threading device of the present invention drives the vertical jacking piece 52 to move horizontally and laterally through the horizontal displacement component 51, thereby accurately displacing the pipe conveying component 53 on the top of the vertical jacking piece 52 to a specified point; the pipe conveying component 53 is lifted to a specified height through the telescopic movement of the vertical jacking piece 52, which solves the problem that the traditional method of directly installing the pipe threader under the pipe gallery support makes it impossible for the pipe to be placed in place before the pipe threader is removed, and the pipe threader is difficult to remove in a narrow space; the spring group 532 is twisted by force, so that the three groups of electric pulleys 535 on the spring base are automatically fitted with the bottom of the pipe to be threaded, thereby fixing the pipe and effectively preventing it from moving. It can adapt to pipe threading operations of pipelines with various diameters, ensure the stable progress of the pipe threading operation, and greatly improve the operation efficiency and accuracy.

[0059] like Figure 7 As shown, the present invention also provides a multi-layer long-span pipe gallery adaptive pipe threading operation method, comprising the following steps:

[0060] S100: Adjust the number of chain plates 132 of the adaptive connection portion 13 between the top plate 11 and the upper wing plate 14 to ensure that the mobile vehicle 33 can move along the pipe corridor;

[0061] S200: The adaptive adjustment frame 1 is placed on the pipe gallery, and the adjustment mechanism 2 is controlled to adjust the dimensions so that the top plate 11 and the bottom plate 12 are respectively pressed against the top and bottom of the pipe gallery. The four sets of adaptive connection parts 13 are driven by the lead screw 22 to automatically adjust their own curvature to fit the contours of the four corners of the pipe gallery.

[0062] S300: After reaching the set first tightening force value, the adjustment rod 31 extends to make the movable carriage 33 fit the outside of the pipe corridor, and the movable carriage 33 drives the adaptive adjustment frame 1 to move along the pipe corridor to the specified point;

[0063] S400: The moving trolley 33 is reset, and the lead screw 22 rotates to adjust the tightening force of the adaptive adjustment frame 1. When the second set value is reached, the first drive motor 21 is controlled to lock and stop, so that the adaptive adjustment frame 1 is tightly held on the outer periphery of the pipe gallery.

[0064] S500: The driving wheel 513 in the horizontal displacement assembly 51 rotates, driving the transmission block 512 through the transmission belt 515, so that the limiting slider 511 moves along the limiting groove 411 to a specified point;

[0065] S600: The vertical pressing member 52 drives the piston rod to extend through hydraulic transmission, thereby lifting the pipeline conveying assembly 53 to a specified height;

[0066] S700: The electric pulley 535 contacts the bottom of the pipe to be penetrated and transmits pressure to the enclosure 533. The spring group 532 is deformed by the force, increasing the angle of the spring base, so that the three groups of electric pulleys 535 automatically fit the bottom of the pipe to be penetrated.

[0067] S800: Start the three sets of electric pulleys 535 to rotate synchronously, thereby driving the pipeline to be penetrated to move forward horizontally until it reaches the designated point;

[0068] S900: After completing the pipe threading operation at this designated point, the electric pulley 535 stops rotating, the vertical top pressure piece 52 and the horizontal displacement assembly 51 are reset in sequence, and the first drive motor 21 drives the screw 22 to rotate to adjust the tightening force of the adaptive adjustment frame 1. After reaching the first tightening force value, the travel drive mechanism 2 drives the adaptive adjustment frame 1 to move to the next designated point for the next round of pipe threading operation.

[0069] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
