The round hole guiding movement device comprises an extending component and a centering guiding mechanism.

The extension assembly comprises a body 1, the body 1 being elongate. The body 1 has a length in the first direction a so as to extend into the circular hole to a depth. In some embodiments, the body 1 is cylindrical. The main body 1 is internally provided with a cavity, and a push rod 2 is arranged in the cavity. The push rod 2 is used for pushing the centering guide mechanism. The push rod 2 may be an automatic push rod, such as an electric telescopic rod or a hydraulic rod. The device can also be a manual push rod, the manual push rod extends out of the main body 1 from the rear end of the main body, and the length of the manual push rod extending into the main body is adjusted by manually holding the manual push rod and pushing.

The centering and guiding mechanism plays a role in centering and guiding in a circular hole or a pipeline. Centering herein means being capable of aligning the bore or the pipe inner axis. The guide finger moves smoothly within the hole or duct.

The centering and guiding mechanism comprises a sliding seat 3 and a fixed seat 4. The sliding seat 3 and the fixed seat 4 are located on the main body 1 and are disposed back and forth in the first direction a. The sliding seat 3 is arranged on the main body 1 in a sliding manner along the first direction A, and the fixed seat 4 is fixedly arranged on the main body 1 in the first direction A, so that the distance between the sliding seat 3 and the fixed seat 4 is adjustable.

The sliding seat 3 is connected to the push rod 2 pushing it to move in the first direction a. When the push rod 2 is an automatic push rod (i.e. an electric push rod or a hydraulic telescopic rod), the push rod 2 can be arranged in the main body 1 behind the sliding seat 3 or in the main body 1 between the sliding seat 3 and the fixed seat 4. A rotational orientation moving mechanism is provided between the push rod 2 and the slide holder 3, and is configured to connect the push rod 2 and the slide holder 3, and to enable the slide holder 3 to rotate about the axis of the main body 1 and the slide holder 3 to move in the first direction a.

The rotational orientation moving mechanism includes a first rotary bearing 5, and the slide mount 3 is rotatably mounted on the main body 1 through the first rotary bearing 5. The fixing base 4 is rotatably arranged on the main body 1 through the second rotary bearing 6, the push rod 2 is arranged in the main body 1, a guide piece 7 is arranged at the movable end of the push rod 2 pushing the sliding seat 3 to move, a slot 100 arranged along the first direction A is formed in the main body 1, the outer end of the guide piece 7 extends out of the main body 1 from the slot 100, and the guide piece 7 can move along the slot 100. An annular groove 300 coaxial with the main body 1 is arranged in the sliding seat 3, the outer end of the guide piece 7 is positioned in the annular groove 300, and circumferential movement along the annular groove 300 can be generated between the guide piece 7 and the sliding seat 3 (the guide piece 7 rotates around the annular groove 300 or the sliding seat 3 rotates around the axial lead of the annular groove 300). The guide piece 7 is in a straight shape perpendicular to the first direction A, the outer end of the guide piece 7 is rotatably provided with a roller 8, the rotation axis of the roller 8 is perpendicular to the first direction A, and the outer diameter of the roller 8 is smaller than the width of the annular groove 300.

The centering and guiding mechanism further comprises at least 3 retraction assemblies. The number of at least 3 retraction components is determined because 3 points determine one plane. At least 3 folding and unfolding components can ensure that the outer end of the centering and guiding mechanism is always contacted with the inner wall of the hole or the pipeline. The included angles between two adjacent folding assemblies in at least 3 folding assemblies are the same, namely when the number of the folding assemblies is 3, the included angle between the two adjacent folding assemblies is 360/3=120°. For another example, the number of the folding and unfolding assemblies shown in the drawing of the utility model is 6, and the included angle between every two adjacent assemblies is 60 degrees.

The articulated arm 9 and the movable arm 10 rotate with the distance between the sliding seat 3 and the fixed seat 4. Before extending into the hole or the pipeline, the opening angle of the movable arm 10 is required to be smaller, so that the movable arm can conveniently extend into the hole or the pipeline, after extending into the hole or the pipeline, the center of the centering guide mechanism is required to be aligned with the center of the hole or the pipeline, and the opening angle of the movable arm 10 is required to be enlarged, so that the outer end of the movable arm 10 is in contact with the inner wall of the hole or the pipeline, and the center of the front end of the centering guide mechanism is required to be aligned with the center of the hole or the pipeline. The pulley 11 at the outer end of the movable arm 10 is contacted with the inner wall in the hole or the pipeline to move in a rolling mode, so that the movement is smoother.

By means of the body 1 of the extension assembly, an elongated body 1 having a certain length can extend into the hole or the pipe. When the guide rod extends, the centering guide mechanism is positioned in front. At this time, the distance between the sliding seat 3 and the fixed seat 4 is larger, the opening angle of the hinged arm 9 and the movable arm 10 is smaller, when the push rod 2 is positioned behind the sliding seat 3, the push rod 2 is in a retracted state, and when the push rod 2 is positioned between the sliding seat 3 and the fixed seat 4, the push rod 2 is in an extended state. After the movable arm 10 is stretched into, the distance between the sliding seat 3 and the fixed seat 4 is reduced by the adjusting push rod 2, the opening angle of the hinged arm 9 and the opening angle of the movable arm 10 are increased, the movable arm 10 is unfolded, and when the pulleys 11 at the outer ends of all the movable arms 10 are contacted with the inner wall of the hole or the pipeline, the center of the fixed seat 4 coincides with the center of the hole or the pipeline, so that the centering is realized.
