To control an a pretightening jack A and stretch-draw jack B.When pretension, the second check valve 41 is closed, and first is unidirectional
Valve 40 is opened, and can drive pretightening jack A, and when integral tension, the first check valve 40 is closed, and the second check valve 41 is opened,
Stretch-draw jack B can be driven；Described automatically controlled overflow valve 36 is arranged on total in-line, plays safeguard protection effect.
In practice of construction, as required, overall control center can work by a control separate unit pumping plant, it is also possible to controls multiple stage pump
Stand and work simultaneously；One pumping plant can only control single set pre-tightening apparatus and the work of integral tension device, it is possible to control to overlap pretension more
Device, many set integral tension devices work simultaneously.
The control method of one enforcement of the present invention is as follows:
1, after installation equipment, input pretightning force setting value, stretching force setting value or displacement by the touch screen of overall control center and set
Being worth and set according to actual demands of engineering, the stretching force setting value when needs are with stretching force for control target, when needs are with displacement
Using displacement setting value, and starting device when value is for controlling target, equipment i.e. works automatically as follows:
2, pretension: overall control center sends instruction, the first check valve 40 opens, and the second check valve 41 is closed, and solenoid directional control valve 30 moves
Making, to pretightening jack A fuel feeding, hydraulic oil sequentially enters each pretension working cell stretch-draw oil from pretightening jack oil-in 10
Cylinder, each pretension working cell piston 9 extends, single hole instrument anchor slab 3 with clamping steel strand wires 1 tool clamping piece 6 together to reach,
Lax steel strand wires 1 are strained, simultaneously the real-time measured pressure value of pressure transducer 32 and by pressure data transmit to overall control center.
After piston 9 extends a stroke, automated backhaul carries out the pretension of next stroke, when piston 9 drives single hole instrument anchor slab 3 backhaul,
The tool clamping piece 6 of single hole moveable anchor resets under the effect of back-moving spring 2, prepares for next stroke pretension, is simultaneously attached to whole
Automated tool anchoring clamping piece self-locking under the effect of steel strand wires gravity on body stretch-draw jack B piston, prevents steel strand wires from returning
Fall, so move in circles, until pretightning force reaches setting value.When a certain steel strand wires pretightning force reaches pretightning force setting value,
Pressure information is transferred to control centre by pressure transducer, and control centre sends instruction, and automatically controlled overflow valve 36 starts, this pretension work
Make unit cannot supercharging again, the piston 9 of this unit quits work, and remaining does not reaches pretension and sets the pretension corresponding to steel strand wires of power
Working cell works on, and so until all steel strand wires all reach pretightning force setting value, overall control center sends instruction, and electromagnetism changes
To valve 30 action, stop pretightening jack A fuel feeding.
3, integral tension: after pretension completes, overall control center sends instruction, and the first check valve 40 is closed, the second check valve 41
Opening, solenoid directional control valve 30 action, to stretch-draw jack B fuel feeding, stretch-draw jack B oil-feed is also stretched cylinder and is carried out presstressed reinforcing steel
Stretch-draw, the simultaneously real-time measured pressure value of pressure transducer 32 data are passed back overall control center, displacement transducer 16 is measured in real time
Shift value displacement data transmits to overall control center.In stretching process, pressing plate 23 and the hollow bolt 24 of locking anchorage 21 can prevent
Intermediate plate gets loose.After stretch-draw jack B stretches one stroke of cylinder, as pressure or displacement are not reaching to setting value, then automated backhaul is carried out
The stretch-draw of next stroke.When stretch-draw jack piston driving automated tool anchor backhaul, the tool clamping piece of automated tool anchor is multiple
Resetting under the effect of position spring, for next stroke pulling preparation, the intermediate plate of locking anchorage 21 is at steel strand wires retraction force or component weight
Self-locking under the effect of power, prevents steel strand wires lax or component falls after rise.So move in circles, until stretching force or displacement reach to set
Definite value.
4, adjust: after drag-line or component stretch-draw put in place substantially, often also need to fine setting.When drag-line or component are transferred by needs
During adjustment, the hollow bolt 24 of locking anchorage 21 is screwed off, take off intermediate plate and can transfer.
