Pipeline lifting device for pipeline laying

Abstract

The invention discloses a pipeline lifting device for pipeline laying, and relates to the technical field of pipeline lifting. The pipeline lifting device comprises a fixing device, a clamping deviceand a telescopic device, wherein the fixing device comprises a bottom plate; two telescopic rods side by side are separately installed at the two opposite end faces of the bottom plate; side plates are fixedly connected to the output ends of the telescopic rods; a plurality of rectangular notches are uniformly formed in the side surfaces of the side plates; a horizontal shaft is installed in eachrectangular notch; a ground cone is fixed on each horizontal shaft; two clamping blocks are symmetrically mounted in a rectangular channel; the inner side surfaces of the clamping blocks are arc-shaped surfaces; the two clamping blocks are connected by a spring; and a bearing is fixed at one end face of a fixing plate. According to pipeline lifting device, pipelines are clamped by the two clampingblocks of the clamping device under the action of the spring, at the same time, the telescopic device controls lifting of the clamping device, and the two clamping blocks slide on guide rails to adapt to the pipelines with different diameters; and it is ensured that the pipelines at different positions are at the same height, and the fixing of the pipelines during the pipeline laying process andthe pipeline laying are facilitated.

Description

technical field [0001] The invention belongs to the technical field of pipeline lifting, in particular to a pipeline lifting device for pipeline laying. Background technique [0002] With the continuous development of modern industry and the expansion of urbanization, road paving is becoming more and more important. During the pipeline laying process, due to the large diameter of the pipeline, each section of the pipeline is relatively long; it is difficult for laying workers to lay the pipeline well. When the pipes are connected to each other, the pipe openings need to be aligned with each other, which brings troubles to the pipe laying workers; at the same time, the underground tunnel is rugged during the pipe laying process, which makes it impossible to ensure that different positions of the pipes are at the same height, which brings difficulties to the pipe laying. [0003] The present invention is dedicated to inventing a pipeline lifting device for pipeline laying, wh...
