Specifically, the gripping mechanism 302 is configured as Fixed on the pipe, the clamping mechanism 302 is connected to the driving device 301 through the buckle portion 303; the buckle portion 303 is provided with a sliding member, and the sliding member of the buckle portion 303 is configured to enable the clamping mechanism 302 to slide relative to the driving device 301 .

In this embodiment, the clamping mechanism 302 can be connected to the driving device 301 by using a buckle portion 303, wherein the buckle portion 303 may include a buckle portion 303 connected in a wedge shape, and the clamping mechanism 302 can clamp the pipeline At this time, since the buckle portion 303 is provided with a sliding member, the clamping mechanism 302 can be appropriately adjusted according to the length of the pipeline, and the pipeline can be more conveniently clamped and easily exited.

Optionally, the clamping mechanism 302 may include two gripping hands 312. The two gripping hands 312 are correspondingly provided with two buckle parts 303, and both of the two gripping hands 312 can be relative to the driving device through the sliding part of the buckle part 303. 301 slides and is configured to move the two grippers 312 toward or in the opposite direction.

Among them, the valve manipulator 300 described in this embodiment can be conveniently and stably installed on the pipeline through two grippers 312. At the same time, the two gripping hands 312 are both connected to the driving device 301 through the buckle portion 303. When the pipeline is long, the two gripping hands 312 can be moved in opposite directions, so that the distance between the two gripping hands 312 is The distance is longer; when the pipeline is short, the two grippers 312 can be moved in opposite directions, so that the distance between the two grippers 312 is shortened, so that the clamping mechanism 302 can be more flexible according to the pipeline Adjust the length appropriately.

It should be noted that the gripper 312 that can be connected to the corner joint in this embodiment can also be snapped with the driving device 301 through the buckle portion 303. The structure of the first connecting portion 100 of the corner joint is similar to that of the gripper 312. The structure of the upper buckle portion 303 is the same, and the structure of the second connecting portion 200 of the corner joint is the same as the structure of the buckle portion 303 on the driving device 301.

Optionally, one gripper 312 of the clamping mechanism 302 is located on the same straight line as the sliding direction of the first connecting part 100 relative to the driving device 301 through the buckle part 303 relative to the driving device 301, and the first connection The portion 100 can drive the other gripper 312 of the clamping mechanism 302 to slide through the second connecting portion 200, and is configured to enable the two grippers 312 to move in opposite or opposite directions.

Wherein, a gripper 312 of the clamping structure can move along the extension direction of the pipeline, and the first connecting portion 100 can also move along the extension direction of the pipeline, so that when the pipeline is long, the One gripping hand 312 and the first connecting part 100 move in opposite directions, so that the distance between the two gripping hands 312 is lengthened; when the pipeline is short, one gripping hand 312 and the first connecting part 100 can face each other The distance between the two grippers 312 is shortened, so that the clamping mechanism 302 can be adjusted more flexibly according to the length of the pipeline; and, when the pipeline after the corner is longer, this The gripper 312 of the time and second connecting part 200 can move in a direction away from the first connecting part 100, so as to better clamp the pipeline after the corner. When the pipeline after the corner is short, this The gripper 312 of the time and the second connecting part 200 can move along the direction close to the first connecting part 100, and can also better clamp the pipeline after the corner, so that the application range of the corner joint and the valve manipulator 300 is wider. wide.

In this embodiment, when the pipeline has a bend, a corner joint may be provided between the clamping mechanism 302 and the driving device 301, and the corner joint may be provided with a first connecting portion 100 and a second connecting portion with an included angle. Part 200, the first connection part 100 and the second connection part 200 are respectively connected to a gripper 312 of the clamping mechanism 302 and the driving device 301, and the first connection part 100 and the second connection part 200 are connected to the clamping mechanism 302 Both the driving device 301 and the driving device 301 can be connected by a sliding member and a clamping part. By providing a corner joint, the position of the gripping hand 312 of the clamping mechanism 302 can be clamped in different directions, which makes the application scope wider.

The foregoing descriptions are only preferred embodiments of the application, and are not configured to limit the application. For those skilled in the art, the application may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included in the protection scope of this application.
