10 are fixed on support groove sidewall;Ball 1-8 and stage clip 1-9 are placed on support bar 1-10;Stage clip 1-9 and support slot bottom
Portion inclined-plane carries out spacing to ball 1-8;Under off working state, spheres of the ball 1-8 close to outside exposes outside support slot;Before
Skewback 1-7 extension bar stretches out size and can adjusted by preceding adjusting nut 1-3 in self-locking mechanism component 1-6, so that in pipe
The caliber scope that mobile robot is adapted to can be adjusted effectively.
As shown in figure 5, aftercarriage component 2 includes aftercarriage 2-1, guide pin bushing 2-2, motor cabinet 2-3, spacer pin 2-4, rear regulation
Nut 2-5, rear lock nut 2-6, rear holddown spring 2-7 and rear self-locking mechanism component 2-8;Self-locking mechanism component 2-8 knot afterwards
The structure of structure and preceding self-locking mechanism component 1-6 is just the same.Self-locking mechanism component 2-8 is circumferential uniform along aftercarriage 2-1 after three;
Set postpones holddown spring 2-7 on skewback 1-7 extension bar in self-locking mechanism component 2-8 afterwards, and stretches into aftercarriage 2-1 by rear
Adjusting nut 2-5 and rear lock nut 2-6 are installed on aftercarriage 2-1;Lock nut 2-6 is arranged on rear adjusting nut 2-5 afterwards
Inner side.Skewback 1-7 extension bar stretching size can be adjusted by rear adjusting nut 2-5 in self-locking mechanism component 2-8 afterwards, so that
The caliber scope for being adapted to movable robot in pipe can be adjusted effectively.Three guide pin bushing 2-2 are each attached on aftercarriage 2-1, and
Respectively prismatic pair is formed with 1 corresponding guide rod 1-2 of front vehicle body component;Spacer pin 2- is set in guide pin bushing 2-2 spacing hole

Set 2-2 is fixed.
As shown in fig. 6, drive component 3 includes motor 3-1 and thread spindle 3-2.Motor 3-1 is installed on aftercarriage
On the motor cabinet 2-3 of component 2;Thread spindle 3-2 nestings are fixed in the output shaft of motor, and with front vehicle body 2-1 center spiral shell
Pit constitutes worm drive.
The operation principle of the expansion self-locking formula movable robot in pipe is:
As depicted in figs. 1 and 2, three be evenly distributed are installed on the front vehicle body component 1 of the movable robot in pipe
Self-locking mechanism component 2-8, driving group after three be evenly distributed are installed on preceding self-locking mechanism component 1-6, aftercarriage component 2
Part 3 is installed on aftercarriage component 2, and front vehicle body component 1 forms prismatic pair with aftercarriage component 2 by guide rod 1-2 and guide pin bushing 2-2,
And it is spacing by spacer pin 2-4.The movable robot in pipe passes through in the thread spindle 3-2 in drive component 3 and front vehicle body 1-1
Heart screwed hole constitutes worm drive, by the motor 3-1 movement for being converted into forward and backward vehicle body component, and driving tube is interior to be moved
Mobile robot is sailed in pipeline internal.Self-locking mechanism component 2-8 ensures in-pipe after three preceding self-locking mechanism component 1-6 and three
Robot is fully contacted with inner-walls of duct.
In pipeline, when the relative aftercarriage component 2 of the front vehicle body component 1 of movable robot in pipe is in lower limit position
(as shown in Figure 7 A) when, robot travels forward, motor 3-1 is rotated forward, rear self-locking mechanism component 2-8 by back pressure,
Due to rear self-locking mechanism component 2-8 ball 1-8 by skewback 1-7 and inner-walls of duct pressure keep self-locking state, and it is preceding from
Latch mechanism component 1-6 is released self-locking by forward thrust, and motor 3-1 power makes front vehicle body component 1 by worm drive
Travel forward, in the process, if motor 3-1 stops operating, robot is maintained at the position transfixion (such as Fig. 7 B
It is shown).When current vehicle body component 1 moves forward to upper extreme position with respect to aftercarriage component 2, front vehicle body component 1 stops movement
(as seen in figure 7 c).
(i.e. aftercarriage component 2 is relative when current vehicle body component 1 moves forward to upper extreme position with respect to aftercarriage component 2
Front vehicle body component 1 be in lower limit position, as shown in Figure 8 A), motor 3-1 reversion, preceding self-locking mechanism component 1-6 by
Back pull, due to preceding self-locking mechanism component 1-6 ball 1-8 by skewback 1-7 and inner-walls of duct pressure keep self-locking state,
Then self-locking mechanism 2-8 is released self-locking, moves forward aftercarriage component 2 by forward pulling force.In the process, if driving
Motor 3-1 stops operating, then movable robot in pipe is maintained at the position transfixion (as shown in Figure 8 B).When aftercarriage component
When 2 relative front vehicle body components 1 move to upper extreme position, motor 3-1 is rotated forward, and rear self-locking mechanism component 2-8 self-lockings are (as schemed
Shown in 8C).Front vehicle body component 1, the alternating movement process of aftercarriage component 2 can make robot be travelled forward with stretch mode.
