Problems solved by technology

[0003] The common problems of the current pipeline robot technology are poor traction ability, low operating efficiency (for peristaltic pipeline robots), and rarely can solve the problem of the robot’s retreat in the pipeline, which limits the application of pipeline robots to a large extent.

Embodiment Construction

[0030] Such as figure 1 As shown, a new peristaltic pipeline robot includes: a front body 1, a rear body 3, a ball screw 2, a support wheel mechanism 4 and a one-way walking mechanism 5.

[0031] Such as figure 2 As shown in a, one embodiment of the peristaltic drive mechanism is that the drive motor is installed on the front body, the ball screw is connected to the front body through the drive motor shaft, the screw nut is fixed on the rear body, and the motor drives the ball screw around its own axis. Turn, the screw nut does not move, so that the screw nut drives the rear body to move along the axis of the screw. Such as figure 2 As shown in b, another embodiment of the peristaltic drive mechanism is that the drive motor is installed on the rear body, the ball screw is fixed to the front body through the flange, and the screw nut is installed on the rear body, which can be driven by the drive motor to rotate. If the ball screw remains still, the movement of the screw n...

Abstract

The invention provides a novel crawling pipeline robot. According to the technical field, the invention relates to the research field of a pipeline robot, in particular relates to a novel crawling pipeline robot, which is provided with single-direction travelling mechanisms and can go backwards. The invention discloses a novel crawling pipeline robot, which is provided with the single-direction travelling mechanisms and a ball screw, and has a back function in a pipeline. The novel crawling pipeline robot comprises a front machine body, the ball screw, a rear machine body, a supporting wheel structure and the single-direction travelling mechanisms; the ball screw is fixed with the front machine body, passes through the rear machine body, and forms a driving device for crawling travel with a screw nut mounted on the rear machine body. Supporting wheel mechanisms are respectively mounted at the both ends of the front machine body and the rear machine body of the robot; and each supporting wheel mechanism is provided with a plurality of supporting wheel legs which are uniformly distributed in the circumference direction, so that the robot is prevented from falling down in the pipeline. Meanwhile, a plurality of the single-direction travelling mechanisms are respectively mounted on the front machine body and the rear machine body, so that the robot walks forwards, and the single-direction travelling mechanisms can be non-efficient by manually pulling a wire, so that the robot goes backwards in the pipeline. The robot provided by the invention has high driving efficiency, can smoothly pass through the linear pipelines, and has the certain tapered pipeline adaptability and strong drawing capability. Meanwhile, the robot further can go backwards in the pipeline.

Description

technical field [0001] The invention relates to the research field of a pipeline robot, in particular to a ball screw peristaltic pipeline robot with one-way traveling wheels that can move backwards. Background technique [0002] The pipeline robot is a mechanical device that can walk in the pipeline. It works in the pipeline and is an intelligent device used to complete pipeline defect detection and repair. It is an important tool to ensure pipeline safety. In today's society, all kinds of pipelines have been widely used. Modern industry, agriculture and daily life are inseparable from pipelines. Pipelines have become one of the important tools for material transportation. Due to the effects of vibration, thermal cycle, corrosion, overload, etc. during use, and the inherent defects that may be hidden by the pipeline itself, the service life is always limited. However, pipelines are generally buried deep underground, in the air or in buildings. The internal structure is int...
