Description

Technical Field

[0001] This utility model relates to the field of pipe-laying machine technology, specifically to a conversion frame structure for a full-rotation pipe-laying machine. Background Technology

[0002] Pipeline construction requires both excavators and pipe-laying machines. Excavators are specifically designed for earthmoving, while pipe-laying machines are dedicated to pipe lifting. This necessitates the deployment of multiple large machines on standby. Excavators (construction machinery) can only perform earthmoving operations such as trenching and backfilling, while pipe-laying machines (lifting machinery) are specifically designed for pipe lifting, requiring the simultaneous deployment of both types of equipment on the same work surface. Therefore, conversion frames are now installed on excavators to enable pipe lifting. However, current conversion frames have limited adjustable lifting heights, making them unsuitable for the pipe-laying needs of engineering projects. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a conversion frame structure for a full-rotation pipe-laying machine, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a conversion frame structure for a full-rotation pipe-laying machine, comprising a mounting base, wherein a mounting component is hinged to the mounting base via a first hinge shaft, one end of the mounting component is fixedly connected to a mounting member, a first telescopic column is placed at one end of the mounting component, a support arm is fixedly connected to one end of the first telescopic column, a first extension column is slidably connected inside the first telescopic column, a plurality of first positioning grooves are provided inside the first extension column, a first bolt is inserted into the surface of the first telescopic column, one end of the first bolt passes through the corresponding first positioning groove and extends to the outside of the first telescopic column, a first nut is threadedly connected to the outside of one end of the first bolt, a hinge seat is hinged to the mounting base via a second hinge shaft, a second telescopic column is placed at one end of the hinge seat, a second extension column is slidably connected inside the second telescopic column, one end of the second extension column extends to the outside of the second telescopic column, a plurality of second positioning grooves are provided on the surface of the second extension column, and a second bolt is inserted into one side of the second telescopic column.

[0005] Preferably, one end of the second bolt passes through the corresponding second positioning groove and extends to the outside of the second telescopic column, and a second nut is threaded onto the outside of one end of the second bolt.

[0006] Preferably, one end of the first telescopic column is fixedly connected to a support arm, and one end of the support arm is fixedly connected to a hanging seat.

[0009] Preferably, each of the mounting bases has mounting holes on its surface, and each mounting hole has a pin inserted inside it.

[0010] This utility model provides a conversion frame structure for a full-rotation pipe laying machine, which has the following beneficial effects: The conversion frame structure of this full-rotation pipe-laying machine, by setting a first telescopic column, a second telescopic column, and mounting components, allows the mounting base to be installed on an existing excavator through mounting holes and pins. By unscrewing the first nut outward from the outside of one end of the first bolt, the first telescopic column can be slid from the outside of the first extension column. The second nut can be unscrewed outward from the outside of one end of the second bolt, and then the second telescopic column can be slid from the outside of the second extension column. One end of the second bolt can then pass through a second positioning groove and outward to the outside of the second telescopic column. The second nut can then be screwed onto the outside of the second bolt. Finally, one end of the first bolt can pass through the first positioning groove and outward to the outside of the first telescopic column, and the first nut can be screwed onto the outside of the first bolt. This fixes the positions of the first and second extension columns, thereby adjusting the height of the conversion frame to accommodate pipe-laying needs. Attached Figure Description
