Description

Technical Field

[0001] This utility model relates to the field of pipe-laying technology, specifically 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. There is a time lag between pipe welding and lifting procedures; excavators must wait during the pipe-laying and trenching phase, resulting in equipment utilization of less than 50%, while specialized pipe-laying machines are completely idle during earthmoving operations. Therefore, the concept of a full-rotation pipe-laying machine was proposed. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides 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 full-rotation pipe-laying machine, comprising a chassis assembly, on which a slewing system assembly is mounted, a base is mounted on the top of the slewing system assembly, and a cab assembly is mounted on the top of the base. A conversion frame assembly is mounted on the base, the conversion frame assembly consisting of a luffing cylinder assembly, a fixed base, a boom assembly, a mounting frame, a third pin and a hinge seat, and a connecting seat. One end of the boom assembly is fixedly mounted with a hinge seat by bolts. The connecting seat is connected to the hinge seat by a third pin. A mounting frame is mounted on one side of the connecting seat, and a pin hole is provided on one side of the mounting frame. A first mounting hole is provided on one side of the mounting frame and below the mounting frame. The system includes a second mounting hole, through which the mounting bracket is fixed to a mounting seat on the base via a second mounting shaft. The mounting bracket is also fixed to a fixing member on the base via a first mounting hole via a first mounting shaft.

A second rotating member is fixedly connected to the telescopic end of the luffing cylinder assembly, and the second rotating member is hinged to the mounting bracket via a second pin and a pin hole. A torque limiter is installed on the conversion frame assembly. The torque limiter uses a pin-type sensor, and the cable runs through the inner cavity of the boom assembly to reduce damage.

[0005] Preferably, a first lifting pulley assembly is installed at the other end of the fixed base, a second lifting pulley assembly is installed at the bottom end of the first lifting pulley assembly, and a lifting mechanism assembly is installed on one side of the boom assembly.
