Novel pipe pushing and pulling device

Abstract

The invention provides a novel pipe pushing and pulling device. The device comprises a base, a pipe pushing and pulling mechanism and a walking mechanism are arranged on the base, the pipe pushing andpulling mechanism is rotatably mounted on the base, the walking mechanism comprises walking wheels and moving plates on the lower portions of the walking wheels, the walking wheels are connected withthe base through lifting hydraulic cylinders, and can completely shrink into the base, walking hydraulic cylinders arranged in the moving direction of the walking wheels are arranged on the moving plates, and two ends of the walking hydraulic cylinders are connected with the moving plates and the walking wheels. According to the technical scheme, through the lifting hydraulic cylinders, supporting stress of the walking wheels and the base can be switched, in cooperation with the walking hydraulic cylinders, stepping walking is achieved, the pipe pushing and pulling pipe mechanism is rotatablymounted on the base, a pushing and pulling mechanism is controlled to do 360-degree rotation in the horizontal direction, and multi-station pipe feeding of the pushing and pulling mechanism can be achieved.

Description

technical field [0001] The application relates to the technical field of pipeline laying, in particular to a novel push-pull pipe device. Background technique [0002] The pipe pusher is used in the construction of large-diameter, long-distance high-pressure pipelines. It is the core device of the direct pipe-laying process. However, the pipe pusher is large in size, has poor flexibility after entering the site, and is difficult to install. Proper adjustment is required, and the alignment accuracy of the pipeline in the originating shaft is relatively high during construction, so the flexibility of the pipe pusher needs to be resolved urgently. Contents of the invention [0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a novel push-pull tube device. [0004] The application provides a novel push-pull tube device, including a base; the base is provided with a push-pull tube mechanism and a walking mechanism; the push...
