Through cable reaching the water surface number by watertight plug and monitoring system so as to obtain the decrement of spring can finally obtain survey
The pressure that test plate (panel) is born.
It is waterborne lay recycling platform 1 detail design side needed to determine openings position after can arrange and water-filling, underwater desilting is made
After industry vehicle 3 is placed in underwater platform 2, underwater platform 2 is transferred by the load-bearing wirerope 115 of drum winder 113.
The sliding face paste Ba Bi of underwater platform 2 is vertically steadily transferred, and adherent pulley 214 plays adherent rolling action.Work as lower end
The contact bar of position sensor 225 enters hole, since the effect contact bar of spring force stretches out, lower end position detector 225
The response of position switch sensor informs that operator's ground pressure tester 226 has entered hole, and operating cyloinder surveys ground pressure
Instrument 226 is tried to stretch out.The sediment piles such as mud, sandstone are arranged at the vertical hole Ba Bi bottom, and underwater platform 2 continues steadily to transfer, connect
The ground measuring test plate (panel) of ground pressure tester 226 is fallen into deposit, and is generated to the ground measuring test plate (panel) of ground pressure tester 226
The pressure data surveyed is transmitted to water surface monitoring system control interface, connect by certain contact pressure, ground pressure tester 226
When 226 screen display pressure value of ground pressure tester changes, slow down 2 lowering velocity of underwater platform, when screen display pressure value reaches shoe
When the safety ground pressure value of belt wheel calibration, stops underwater platform 2 and transfer.
It is transferred to after openings position stablizes after underwater platform 2, when the contact bar of upper end position detector 212 enters hole,
Since the effect contact bar of spring force stretches out, the position switch sensor response of upper end position detector 212 is informed on operator
End position detector 212 has entered hole.
After upper end position detector 212 reaches hole upper end position, collapsing struts 229 are fully extended in hole, wait stretch
Out completely after, the round fagging 231 in each two of left and right is extend out to be contacted and stretching is to setting pressure with two sidewalls in hole.Two-way circle
231 contact surface side of fagging has a large amount of round tooths, is conducive to improve the frictional force between round fagging 231 and hole wall, reduces opposite
Slip risk.Two-way circle fagging 231 is connect with collapsing struts 229 by ball-type articulated joint 230, can be automatically adjusted two-way round
The angle of fagging 231, guarantee are bonded with hole wall perfection, are conducive to improve tightening mechanism to the adaptability of hole wall.
Behind 229 two sides stretching Dong Bi of collapsing struts, operation left and right two overlap joint oil cylinder 228 stretches out, and pushes lapping plate 227
It is hingedly extend out in hole and is compacted to hole lap-joint, lapping plate 227 is articulated with 2 edge of underwater platform, 227 lower face of lapping plate
There are a large amount of long tooths, improves the frictional force between lapping plate 227 and hole lap-joint, advantageously reduce lapping plate 227 and taken with hole
Connect the sliding phenomenon at place.
After the overlap joint of lapping plate 227 is firm, hole is docked by lapping plate 227 with underwater platform 2, operates underwater desilting
Operation Van 3 enters in hole through lapping plate 227 carries out dredging operation.
No camera picture less important work can be achieved in entire decentralization process substantially, is completely adapted to the water bodys such as waters along the Yellow River
Muddy waters, it is limpid for part water quality, it is seen that spend higher waters, decentralization removal process can be by underwater desilting Operation Van 3
324 picture of front camera of front carries out picture less important work.
Referring to Fig. 3, the effect of underwater operation vehicle 3 is walked in hole, rubs deposit in hole and fragment suction is appeared
