After the locking gear 403 of tight nut apparatus 4 and the locking nut gear 104 of tubular pole membrane module 1 pass through adjusting, the two is mutually nibbled
It closes, realizes and pipe pile mould 101 is locked.When wrench is by tensioning a distance, locking gear 403 will lock pipe pile mould 101
Tightly, when coupling mechanism force is to certain value, nut-locking device 4 can also be popped up, therefore locking gear 403 can be to pipe pile mould
101 are locked in real time.
During tubular pole contraposition, tensioning equipment 3 and tubular pole membrane module 1 come directly towards 301 apart from when differ close, detecting tensioning
Whether contacted with pipe pile mould 101 in the tubular pole membrane module 1 so that guide rod travel switch 607 and be located at lock sleeve 501 in
The big stroke travel switch 513 of 2 of portion generates signal and moves horizontally to control lifting platform horizontal displacement device 8, can be applicable in
In the tensioning of the pipe pile mould 101 of different length.
As shown in figure 19,3 nut sliders 705 are radially even with lock sleeve 501 respectively in the locking covering device 5
3 505 holes of locking pin of distribution match；Locking pinion gear 506 and helical gear 504 in the case where locking servo motor 508 drives
It is meshed, locking pin 505 moves one section, and 505 end of locking pin and the tubular pole membrane module along lock sleeve 501 radially inwards
1 wrench pull rod 107 has certain spacing, realizes the connection of locking covering device 5 and tubular pole membrane module 1, prepares for tensioning.
When tensioning, the angular displacement sensor 201 of caliber detection device 2 controls the oil pressure of tensioning oil cylinder 302 in tensioning equipment 3
The pipe pile mould 101 of different size is matched with the dwell time.System issues instruction, association from the executing agency of trend Combined hydraulic valve
Reversal valve and the shut-off valve direction of motion are adjusted, reinforced bar stretching work is carried out, for tensioning equipment 3 equipped with high-precision sensor, dynamic is real
When detection system in tensioning pressure, after up to standard, control combination valve enters pressure maintaining, after the completion of operation by system issue pressure release refer to
It enables, coordinates reversal valve and shut-off valve counter motion, and oil cylinder is made to retreat return, complete tensioning workflow.
When tensioning terminates, in the case where locking servo motor 508 drives, locking pin 505 is moved radially outward along lock sleeve 501
One section, slider stroke switch 511 pair nut sliders 705 radial positioned at lock sleeve 501 carry out radial limit.First carry out horizontal shifting
Dynamic, the inclined-plane of wedge block 402 is in contact with the inclined-plane of locking nut gear 104 in tubular pole membrane module 1 in nut-locking device 4,
Nut-locking device 4 can be smoothly detached from.
Reciprocation cycle repeats the above-mentioned course of work, unremitting pipe pile mould contraposition, locking, connection, tensioning etc. may be implemented
Movement.
