5 connect with two racks 3, and telescopic rod and rack form revolute pair, and telescopic rod 4 can be with vertical with telescopic rod 4 at shaft 5
Direction is axis rotation, and the shaft 5 in the same rack 3 is not distributed in all on same straight line;Parallel institution has one
The freedom degree of Forward and around the freedom degree rotated with telescopic rod vertical direction, when every bar collapsing length is identical, this mechanism is
Plane mechanism, when plurality of rods stretch extension elongation difference, mechanism becomes space parallel mechanism, and a gripper is relative to another
A gripper is moved in solid space.
Two grippers 1 are connect by rotating electric machine 6 with two racks 3 respectively, and rotating electric machine controls gripper rotation;
Each gripper 1 includes two symmetrical folding claws 7 and controls two folding claws 7 releases respectively and clamp
Two groups of clamping cylinders 8, folding claw 7 includes the multistage snap ring that can fold and unfold, when multistage snap ring is unfolded, is adapted to big straight
The cylindrical body of diameter adapts to the cylindrical body of minor diameter when multistage snap ring folds, and the exhibition of multistage snap ring is selected according to the size of cylindrical body
Open or fold series.
Adaptive folding finger in parallel of the invention is adapted in space the cylindrical body being interspersed and diameter is different, energy
It is crawled on enough cylindrical bodies or class cylindrical body being interspersed in space.It is of the invention use process is as follows:
The adaptive folding finger in parallel integrally clamps on the cylinder first, if desired moves forward, then front end gripper
Clamping cylinder control the releases of two foldings claws, more telescopic rods of parallel institution stretch out simultaneously, then the folder of front end gripper
Two scored card claw clips of tight cylinder control are tight, and the clamping cylinder of rear end gripper controls two folding claws and unclamps, parallel institution
More telescopic rods retract at the same time, and complete the Forward of adaptive folding finger in parallel.
If adaptive parallel connection folding finger needs to crawl into an other cylindrical body in space, a gripper pine is first allowed
It opens, then more telescopic rods of parallel institution do not stretch out simultaneously or retract (specifically which root telescopic rod is stretched out or retracted according in addition
The position of a piece cylindrical body and determine), lift the gripper, parallel institution is converted into space parallel mechanism, two rotating electric machines
Gripper rotation is controlled, gripper is moved to suitable position with parallel institution cooperation and is then clamped;Another gripper unclamps at this time, leads to
It crosses parallel institution and is moved to position identical with previous gripper with the cooperation of rotating electric machine, complete creeping between column and column.Such as
Shown in Fig. 5, the adaptive state of folding finger in parallel when being pipeline antarafacial;As shown in fig. 6, adaptively in parallel when parallel for pipeline
The state of folding finger;As shown in fig. 7, for pipeline adaptive state of folding finger in parallel when vertical.
If caliber changes, multistage snap ring expansion or folding select expansion or folded state according to the size of caliber.
In conclusion steering of the invention and traveling use rotating electric machine and the concatenated structure of two-freedom-degree parallel mechanism
Form, steering mode is flexible and changeable, is moved on the cylindrical body that can be interspersed in space.And gripper of the invention
