Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] The step-by-step pipeline inner wall defect image acquisition robot of the present invention, such as Figure 1-Figure 5 As shown, it includes a first locking device 1, a power device 2, a second locking device 3 and an image acquisition device 4 connected sequentially through a flexible shaft 500 from top to bottom;

[0041] Both the first locking device 1 and the second locking device 3 include a hollow locking device box 101, an electromagnet 105 is installed axially in the locking device box 101, and an output rod on one side of the electromagnet 105 is installed. There is a wedge-shaped slider 104, and the concave surface of the wedge-shaped slider 104 is provided with a locking column end cover 103. The locking column end cover 103 is connected with the corresponding groove on the outer wall of the locking device box 301 by screw...

Abstract

The invention discloses a stepping type pipeline inner wall defect image acquiring robot. The stepping type pipeline inner wall defect image acquiring robot comprises a first locking device, a power device, a second locking device and an image acquiring device which are sequentially connected through a flexible shaft from top to bottom. The first locking device and the second locking device both comprise hollow locking device box bodies. Each locking device box body is internally provided with an electromagnet in the axial direction, wherein an output rod on one side of the electromagnet is provided with a wedge-shaped sliding block, a locking cylinder end cover is arranged at the concave face position of the wedge-shaped sliding block, the locking cylinder end cover is connected with a corresponding groove in the outer wall of the locking device body through a screw, a locking cylinder is embedded into the locking cylinder end cover, the locking cylinder is sleeved with a reset spring, and the round head end of the locking cylinder makes contact with the concave surface of the wedge-shaped sliding block. By means of flexible shaft connection, flexibility among the modules is guaranteed, clamping caused by the too large pressure angle during transmission is avoided, the capacity of passing through a 90-degree bend is achieved, and the axial propelling of the pipeline robot is achieved under the assistance of a flexible shaft channel.

Description

technical field [0001] The invention belongs to the technical field of pipeline detection equipment, and in particular relates to a step-by-step pipeline inner wall defect image acquisition robot. Background technique [0002] Pipeline transportation is widely used in petroleum, chemical industry and urban water supply and drainage due to its advantages of good safety, strong continuity, large transportation volume, good sealing and not easy to be disturbed. Due to the harsh working environment, long-term use will lead to corrosion of the pipeline wall, impurity deposition, mechanical damage and other problems. If it is not repaired in time, it will definitely cause environmental pollution and waste of resources. This requires regular inspection and maintenance of the pipeline, but most of the pipelines are buried underground, and it is difficult to find the leak point through the conventional line inspection method. In addition, the pipeline is long and the distribution is ...
