Auxiliary manipulator is precisely located, and this is to realize by seeing the monitoring of way system and propulsion system,
Auxiliary manipulator plays the effect of auxiliary positioning track.Auxiliary manipulator has four degree of freedom, has certain
Operability, specifically: the screw-nut body that motor 25 controls, controls telescopic arm 28 above-below direction
Stretching motion (such as Fig. 2)；Motor 16 controls the rotary motion (such as Fig. 1) of gripper；Motor 31 is (such as figure
3) swing (such as the Fig. 2) of gripper is controlled；The quadric chain that hydraulic cylinder 15 controls, hydraulic cylinder 15
Promote the driving plate 13 connected with piston rod to move, it is achieved the clamping of claw 10 with unclamp.Auxiliary manipulator
By the stretching of telescopic arm 28 and the rotation of gripper and swing make mechanical hand close to suspended span pipeline, directly
To location bar 12 and suspended span tube contacts, after judging contact, hydraulic cylinder 15 is regained, until and piston rod
Limited block 27 encountered by the driving plate 13 being connected, and hydraulic cylinder 15 is locked, and now claw 10 has clamped suspended span pipe
Road, claw 10 is provided with four wheels 11, when moving ahead along pipeline after claw clamping suspended span pipeline.
(3), after positioning along predetermined route jackstone auxiliary manipulator, come real by the control of propulsion system
Existing jackstone device carries out jackstone along presetting route.Propulsion system is made up of 6 hydraulic pushers, because examining
Considering to powerful propeller, so using hydraulic motor propeller, in horizontal direction, 4 hydraulic pushers are adopted
By the mode of being circular layout, two other hydraulic pusher primarily serves the effect hidden, additionally added with buoyancy
The part deadweight of jackstone device offset by material 2, reduces propeller control dynamics.So pass through propeller
Current are overcome to guide falling rocks pipe to move forward, simultaneously by stone dumper upthrow exactly along the presetting route of submerged pipeline
Under rubble enter center-aisle 8 along falling rocks pipe, can be led by hydraulic cylinder 33 regulation at falling rocks targeting port
To the angle of inclination of plate 32, control the angle of dishing out of rubble, make rubble in suspended span pipeline both sides completed buried.
