In conjunction with shown in Fig. 1 to Fig. 6, one is done specifically to the course of work of the cambered surface self-reacting device 100 of the utility model
It is bright:
Cambered surface self-reacting device is connected to the movable equipment with driving part by connecting flange 41, before cleaning,
Rotating electric machine 11 is opened and driving arm 12 starts to rotate, and cambered surface self-reacting device is under the drive of movable equipment along cambered surface side
It marches forward, cambered surface self-reacting device is contacted with cambered surface for line, and protection wheel 8 is as third contact point to keep balancing, expansion bend 2
The data feedback of oil cylinder inner fluid that detects of displacement sensor to controller, controller controls oil liquid from the second hydraulic fluid port 222
Into the second oil cylinder 226, to drive the movement of piston rod 23, simultaneously compression elastic piece 21, flexible by adjusting expansion bend 2 make indirectly
The center line of connecting flange 41 and the center line of bracket 12 are located along the same line.When cleaning, cambered surface self-reacting device close to
Cambered surface is cleared up, the spring 9 on position-detection sensor 10 is adaptively contacted with cambered surface and generated by the extruding force of cambered surface
Elasticity and when reaching object elastic power, position-detection sensor 10 to controller, protects the elastic force data feedback of spring 9 at this time
Keep 14 is in rolling contact and makes cleaning head 13 and bracket 12 to keep safe distance, controller control first with cambered surface respectively with cambered surface
Oil cylinder 225 and 226 pressure release of the second oil cylinder and to keep in-oil cylinder pressure be zero, the elasticity of the elastic component 21 in the second oil cylinder 226
Power discharge and press on piston rod 23 so that three expansion bends 2 toward cambered surface direction generate elasticity compress, two of them expansion bend 2
Elastic force so that bracket 12 is close to cambered surface in the diametrical direction of cambered surface and keep certain contact force, a remaining expansion bend 2 makes
Protection wheel 8 is pressed towards cambered surface, and last 12 high speed rotation of bracket simultaneously clears up cambered surface；When cambered surface self-reacting device is in movable equipment
When lower cleaning structure 1 being driven to deviate from cambered surface, cleaning structure 1 can be close to cambered surface always under the elastic force of elastic component 21, from
And make no matter cleaning structure 1 can be fitted the cambered surface being cleaned always in the state that how rear end connecting shaft changes；In addition, clear
Reason mechanism encounters the cambered surface of out-of-flatness when mobile, cause the center line of connecting flange 41 that can not be overlapped with the diameter of cambered surface, cambered surface
The micro tilting relative to cambered surface of self-reacting device makes the elastic component 21 in expansion bend 2, and deformation occurs, at the same with 2 pivot of expansion bend
The second universal joint 6 connect, which deflects, enables the center line of bracket 12 not be overlapped with the center line of connecting flange 41, to make bracket
12 keep being fitted and running well with cambered surface always.
Since expansion bend 2 is incorporated cleaning structure by the utility model and is provided with elastic component 21, the bullet in expansion bend 2
Property part 21 can provide expansion bend 2 described in a pushing tow piston rod stretch out elastic force, therefore, the energy when being actively condensed of expansion bend 2
So that the total length of cambered surface self-reacting device is less than the internal diameter of tunnel, and then makes equipment that can totally can smoothly enter into tunnel.Expansion bend 2
The elastic force of elastic component 21 can also be initiatively adjusted and discharged after cambered surface self-reacting device can smoothly enter into tunnel, thus logical
The elastic force for crossing elastic component 21 makes the piston rod auto-extending of expansion bend 2 in 2 pressure release of expansion bend, and then drives structure 1 of removing contamination
Press and be cleaned cambered surface, the structure 1 that makes to remove contamination adaptively is fitted cambered surface in the diametrical direction of cambered surface and is close to preferably clear
Reason, responds that the time is short, and cleaning effect is good and good cambered surface fitting can be to avoid the surface for the scratch tunnel of structure 1 of removing contamination；It is comprehensive
On, it is different to tunnel attachment to realize that the cambered surface self-reacting device of the utility model can adaptively be bonded cambered surface for clearance
Object cleaning, adaptable, the response time is fast, the cambered surface that cleaning effect is excellent while effective protection is for clearance.
Natural, this cambered surface self-reacting device can also be used in nuclear power station other occasions in addition to tunnel,
It can also be used in the technical field that other cambered surfaces are removed contamination, be not limited with nuclear power station field.
It above disclosure is merely preferred embodiments of the utility model, certainly cannot be practical new to limit this with this
The interest field of type, therefore equivalent variations made according to the patent scope of the utility model still belong to the utility model and are covered
Range.
