Adaptive pipe-holding apparatus

Abstract

The invention provides an adaptive pipe-holding apparatus, comprising a lifting manipulator and an open and closed pipe-holding mechanism. The pipe-holding mechanism includes a semi-closed frame; vertical rollers are arranged on a left side and a right side of the frame respectively; a V-shape collet is hinged to a lower part of the frame; the V-shape collet realizes open and close movement relative to the frame through a performer; the V-shape collet is hinged to two roller racks through pins; each roller rack can conduct heeling rotation relative to the collet around the pin; two sides of each roller racks are respectively hinged to a side plate through the pins; each side plate can conduct pitching rotation relative to the roller rack around the pin; each side plate is hinged to a plurality of rollers through pins, and each roller can rotate around the pin thereof; rollers on two roller racks form a V-shape roller set. The apparatus of the invention has a simple structure, is safe,reliable and adaptive to shaking of the pipeline and keeps fit to two sides of the pipeline; besides, an elastic shock-absorbing pad can effectively absorb impact on the pipeline, and a locking mechanism further enhances working reliability.

Description

technical field [0001] The invention relates to a device for elevating and supporting elongated flexible round pipes such as pipes. Specifically, it is a pipe holding device, which is suitable for continuous mobile construction of long pipelines. Background technique [0002] Due to its many advantages such as integrated efficiency and safety, pipelines are widely used in many fields including water conservancy, energy, and communication. During pipeline construction, especially during pipeline maintenance, it is necessary to lift and support the pipeline for related operations. [0003] At present, the commonly used methods are that the manipulator grabs the pipe, and then directly lifts and moves the pipe; or the manipulator grabs the pipe and uses the rotatable roller group to support it, and then carries out the pipe lifting and moving operation; these operation methods are simple and convenient, but have the following disadvantages: 1. It cannot be guaranteed that all...

[0003] At present, the commonly used methods are that the manipulator grabs the pipe, and then directly lifts and moves the pipe; or the manipulator grabs the pipe and uses the rotatable roller group to support it, and then carries out the pipe lifting and moving operation; these operation methods are simple and convenient, but have the following disadvantages: 1. It cannot be guaranteed that all the rollers in the roller group fit the pipe completely, and the contact points are reduced, resulting in a large contact force between the rollers and the pipe, which is easy to damage the pipe; 2. The roller group has no other shock-absorbing measures except the rubber cladding, which cannot effectively reduce Small pipelines are subjected to various impacts; 3. When the roller group is working, it has no other mechanical locking functions except for the closing of the actuator. It is unreliable when working for a long time, and cannot meet the continuous mobile construction requirements of long-line pipelines.
