Work process of the present invention:
Locking plate 8 in the course of the work, is first upwards turned before work by one multifunctional manual dilator of the present invention
Dynamic, make draw-in groove 82 and engage with the chuck 51 of arm-tie 5 of rising progressively, being then placed on by bedplate 1 can load-bearing
On table top, bearing platform 26 is held the object needing to lift, by the rocking bar 63 that fluctuates, makes bearing base 2
Constantly rising, owing to being provided with oblique cambered surface 232 on lateral pin 23, described lateral pin 23 is only by pulling force upwards
Shi Caineng makes lateral pin 23 to a Slideslip, makes bearing base 2 or seat 3 of creeping increase, the mistake of rocking bar 63 pressure
Seat 3 of creeping in journey rises, and bearing base 2 is played a supporting role, during rocking bar 63 is lifted on bearing base 2
Rising, seat 3 of creeping plays the effect of support, after instrument uses, needs draw-in groove 82 and arm-tie 5 of rising progressively
Chuck 51 separately, rocking bar 63 can freely move up and down, the plate that climbs being enclosed within dilator by slide cartridge 91
On, slide cartridge 91 can be fixed on climb on plate by slide cartridge pin hole 911,93 can be by by presenting a theatrical performance as the last item on a programme
Object flattens；Object, anti-sliding stop can be preferably withstood, it is possible to logical by the fixing groove 912 on slide cartridge 91
Cross and isometric for steel pipe bar-shaped object is penetrated cooperation how lateral opening 922 or coordinates circular hole 921 to realize multiple manual expansion
Device with the use of.By plate holder plate 107 fixed expander that climbs, when needing to use pulling force, by rope or
Chain passes bottom branch line bar 106, the end of rope or chain be separately fixed at dilator bearing base and
On the object that needs draw, rope or chain is made to produce pulling force by the movement of bearing base, when needing adjustment direction,
Need to extract pin, rotate rotational sleeve 104, then pin is inserted on pin-and-hole 103.
One multifunctional manual dilator of the present invention, device structure is simple, and load-bearing quality is big, simple to operate,
Being convenient for carrying transport, failure rate is low, maintenance is convenient, and product component required precision is the highest, produces into
This is relatively low, and application is flexible simultaneously, strong adaptability, it is possible to be greatly expanded the range of application of Manual expander, energy
Enough meet more demand, it is possible to adapt to more complicated geographical environment, by some particular design on equipment
Multiple Manual expander can be made preferably to coordinate, and dilator not only has the function of support simultaneously, it is also possible to borrow
This auxiliary equipment is helped to be flattened by object, it is possible to make dilator realize by the supporting role of branch line bar 106
The function drawn, can make dilator rotate flexibly by the rotation of rotational sleeve 104, it is possible to according to special
Condition, better meet demand, device structure is simple, easy to operate, reliable operation, strong adaptability.
Above-described embodiment is the description of the invention, is not limitation of the invention, any simple to the present invention
Scheme after conversion belongs to protection scope of the present invention.
