一种管道抗变形能力的检测设备

Abstract

本实用新型适用于管道检测技术领域，提供了一种管道抗变形能力的检测设备，包括工作台，工作台上方固定连接有顶板，顶板上可升降地设置有用于挤压管道的弧形压板，工作台上间隔设置有多个用于支撑管道的Y字型支撑架，每两个支撑架之间可升降地设置有一组驱动组件，驱动组件抬升至最高点时可接触管道底部的两侧并驱动其移动。该管道抗变形能力的检测设备，通过驱动组件和导料架的配合驱动管道在测试设备上进行移动，可以对管道不同的位置进行检测，不需要工作人员进行手动推送管道，节省了部分人力劳动力，同时设置了调高组件，在管道进行挤压测试时，调高组件将驱动组件下降并与管道分离，不会对测试中的管道造成影响，提高了检测效率。
