Embodiment 1

[0047] like Figure 1 to Figure 6 Shown, the present invention provides a kind of pipeline external movement device, with reference to figure 1 As shown, it includes a pipe frame, a moving mechanism and a control unit arranged on the pipe frame.

[0048] The pipe frame is suitable for erecting on the outer ring of the pipe, and includes a mother frame assembly and a child frame assembly connected to form a ring structure through a curvature adjustment assembly. The pipe frame can be designed as a full-size ring structure, but in order to facilitate disassembly without affecting the detection efficiency, it can be designed as a non-full-size ring structure, that is, there is a gap 3 in the ring structure. The designed notch 3 makes it necessary to connect one end of the mother bracket assembly and the sub-bracket assembly when the pipe frame is installed on the outer ring of the pipeline, that is, the opposite end of the mother bracket assembly and the sub-bracket assembly is th...

Embodiment 2

[0064] refer to figure 1 and figure 2 , on the basis of Embodiment 1, the pipe moving device of this embodiment also includes an infrared obstacle avoidance sensor 15 and a gas sensor or humidity sensor 16 .

[0065] Specifically, a first fixed rod 5a is provided between the front and rear female brackets in this embodiment; the middle of the first fixed rod 5a is equipped with an infrared obstacle avoidance sensor 15 electrically connected to the control unit.

[0066] When the moving device outside the pipeline is in the process of moving, if the infrared obstacle avoidance sensor 15 detects an obstacle, the infrared obstacle avoidance sensor 15 sends a signal to the signal processor 14, and the control unit also includes an alarm connected to the signal processor 14 , the alarm sends out an obstacle alarm signal.

[0067] A second fixing rod 5b is provided between the front and rear sub-brackets; a gas sensor or a humidity sensor 16 electrically connected to the control ...

Abstract

The invention relates to the technical field of pipeline engineering, in particular to a moving device outside pipelines. The device comprises a pipeline frame body, a moving mechanism and a control unit, wherein the pipeline frame body is suitable to be set up on an outer ring of the pipeline, and includes a main frame component and a secondary frame component which are connected by a first curvature regulating component to form a ring structure; the moving mechanism includes a driving component which is installed on the pipeline frame body, and a traction wheel component which is connected with the driving component and suitable for driving the pipeline frame body to move along the outer ring of the pipeline; the control unit is suitable for an electric connection with the driving component.

Description

technical field [0001] The invention relates to the technical field of pipeline engineering, in particular to a pipeline external movement measuring device. Background technique [0002] When inspecting and maintaining pipelines, sometimes, because the length of the pipeline is relatively long, it takes time and effort for the staff to manually perform the pipeline work; in these cases, it is necessary to use the pipeline external moving device to work on the pipeline. [0003] Due to the different outer diameters of different pipes, many current pipe outer movement devices are only fixedly adapted to pipes with one outer diameter, and even if the existing pipe outer movement devices can walk along the pipe, they cannot go around the pipe. Make a circular motion to perform all-round operations on the outer wall of the pipe. Contents of the invention [0004] The purpose of the present invention is to provide a pipe moving device to solve the technical problem of automatic...
