Problems solved by technology

It is mostly used for internal inspection of pipelines. When inspecting oil and gas pipelines, it is inevitable to empty the pipelines, which will affect the efficiency and economic benefits of oil transportation to a certain extent, and such robots cannot conduct inspections on oil pipelines during oil transportation. Real-time detection, it is difficult to detect oil pipeline failures in time
In addition, some pipe climbing robots are designed to be difficult to cross obstacles such as oil and gas pipeline support bases and pipeline connection bosses, and cannot effectively detect oil and gas pipelines
[0003] In summary, in view of the complex detection environment of the above-ground oil and gas pipeline, the difficulty of manual detection, and the existence of support bases, pipeline connection bosses and pipeline bending due to the laying technology of the above-ground oil and gas pipeline, how to realize the super-surpassing of the external detection robot? Obstacle ability and adaptive adjustment ability have become technical problems that need to be solved urgently

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] Such as figure 1 , figure 2 As shown, the present invention provides a double-claw type obstacle-crossing direction adaptive detection robot outside the pipeline, which is composed of a mechanical system and a circuit system, and the mechanical system is controlled by the circuit system. The mechanical system includes a pipe grasping mechanism, a connecting device and a driving device. The pipe grasping mechanism is arranged on the connecting device, and the driving device is connected with the pipe grasping mechanism. The driving device drives the pipe grasping mechanism to act under the control of the circuit system.

[0022] The gripping mechanism includes a first mechanical claw 1 , a second mechanical claw 2 , a third mechanical claw 3 and a fourth mechanical claw 4 . Among them, the first to fourth do not represent the order of install...

Abstract

The invention relates to a double-claw type obstacle-crossing direction-adaptive pipeline external detection robot. The detection robot is composed of a mechanical system and a circuit system, wherein the mechanical system is controlled by the circuit system to work; the mechanical system comprises a tube grasping mechanism, a connecting device and a drive device; the tube grasping mechanism is arranged on the connecting device; the drive device is connected with the tube grasping mechanism; and the drive device drives the tube grasping mechanism to act under control of the circuit system. According to the double-claw type obstacle-crossing direction-adaptive pipeline external detection robot, a mechanical structure is combined with a circuit system, so that obstacle-crossing capacity and adaptive adjustment capacity of the external detection robot are realized.

Description

technical field [0001] The invention relates to a detection device outside a pipeline, in particular to a double-claw type cross-obstacle direction self-adaptive detection robot outside a pipeline. Background technique [0002] Existing oil pipeline inspection robots are mainly divided into seven categories: fluid-driven, wheeled, crawler, supported, walking, peristaltic and screw-driven. It is mostly used for internal inspection of pipelines. When inspecting oil and gas pipelines, it is inevitable to empty the pipelines, which will affect the efficiency and economic benefits of oil transportation to a certain extent, and such robots cannot conduct inspections on oil pipelines during oil transportation. Real-time detection makes it difficult to detect oil pipeline failures in time. In addition, some pipe climbing robots are designed to be difficult to cross obstacles such as oil and gas pipeline support bases and pipeline connection bosses, and cannot effectively detect oil...
