Embodiment 1

[0060] Such as Figure 1 to Figure 3 The shown outer pipeline detection robot includes an outer wall assembly and an inner wall assembly. Both the outer wall assembly and the inner wall assembly include a number of electronically controlled adsorption devices, which can be adsorbed on the outer wall of the pipeline to be detected; it also includes a main shaft 25, and The transmission assembly connected to the main shaft 25: when the main shaft 25 rotates forward, the transmission assembly drives the outer wall assembly forward, and drives the electronically controlled adsorption device on the outer wall assembly to alternately move closer to and away from the pipeline to be detected; when the main shaft 25 reverses, the transmission The assembly drives the inner wall assembly forward.

[0061] In this embodiment, the main shaft 25 is driven to rotate by a motor, and the output end of the motor can drive the bevel gear 10 to rotate by any existing method. When the motor rotat...

Embodiment 2

[0064] An outer pipeline detection robot, on the basis of embodiment 1, the outer wall assembly such as Figure 5 As shown, it includes two claw arms 2, and the claw arms 2 are arc-shaped with the concave surface downward; it also includes a connecting rod 4 that is rotationally connected with the claw arms 2, and the connecting rod 4 is used to connect with the transmission assembly; the electric control on the outer wall assembly The adsorption device is an outer wall electromagnet 1 hinged with a claw arm 2 . It also includes a casing 8; the claw arm 2 is hinged with the casing 8 through the connecting shaft 7, the main shaft 25 is rotatably connected with the casing 8 through a bearing 26, the claw arm 2 is fixedly connected to the connecting rod shaft 3, and the connecting rod 4 is rotatably connected to the connecting rod shaft 3 .

[0065] Transmission components such as Figure 4 As shown, it includes the gear 13 fixedly connected with the main shaft 25, the grooved ...

Embodiment 3

[0086] A kind of external pipe detection robot, on the basis of any one of the above-mentioned embodiments, such as figure 2 and Figure 7 As shown, the inner wall assembly includes an inner wall frame 17, two wheel frames 19 located on the side of the inner wall frame 17 facing the pipeline to be detected, and several guide wheels 20 located at the bottom of the wheel frame 19; also includes a steering assembly;

[0087] The steering assembly includes two circular grooves respectively located at the front and rear ends of the inner ledge 17, and a runner 28 located in the circular groove. The runner 28 is coaxial with the circular groove, and an annular gap 29 is formed between the runner 28 and the wall of the circular groove; The retainer 30 is fixed in the annular gap 29, the dial 15 located in the annular gap 29 is arranged on the runner 28, and the elastic member 16 located in the annular gap 29 is arranged between the retainer 30 and the dial 15; two runners 28 They a...

Abstract

The invention discloses an outer pipeline detection robot and a walking method, the outer pipeline detection robot comprises an outer wall assembly and an inner wall assembly, the outer wall assembly and the inner wall assembly each comprise a plurality of electric control adsorption devices, and the electric control adsorption devices can be adsorbed on the outer wall of a detected pipeline; the outer pipeline detection robot further comprises a main shaft and a transmission assembly connected with the main shaft. When the main shaft rotates forwards, the transmission assembly drives the outer wall assembly to advance and drives the electric control adsorption devices on the outer wall assembly to alternately move close to and away from the detected pipeline; when the main shaft rotates reversely, the transmission assembly drives the inner wall assembly to advance. According to the outer pipeline detection robot and the walking method, the problem that in the prior art, a crawling robot is not suitable for long-distance oil and gas conveying pipeline outer wall detection is solved, and the purpose that the characteristics that the long-distance oil and gas conveying pipeline is gently arranged, long-distance operation is needed and the like can be achieved.

Description

technical field [0001] The invention relates to the field of oil and gas pipeline detection, in particular to an external pipeline detection robot and a walking method. Background technique [0002] With the laying of a large number of long-distance oil and gas pipelines, it is particularly important to regularly inspect and maintain these oil and gas pipelines. Pipeline robots are one of the important means for such operations. In the field of oil and gas pipelines, a lot of research focuses on the structural optimization and improvement of robots in pipelines to adapt to the special operating environment of oil and gas pipelines, but there are relatively few studies on detection robots outside oil and gas pipelines. In the prior art, a pole-climbing robot has appeared in the remaining fields, which can climb and walk along a pole-shaped object, and can be detected by carrying detection equipment on it. However, this type of existing technology is difficult to adapt to the...
