Detailed description of the invention
In Fig. 1,2,3,4, maxillary grillage 1 is sitting on opening gear 2, and lower jaw grillage 3 is by three studdles 9 and spiral shell
Female 10 are integrally fixed with maxillary grillage 1, and jaw assembly 4 is located in the cavity between maxillary grillage 1 and lower jaw grillage 3, jaw
Assembly 4 is two, is respectively at the opening both sides of opening gear 2, is symmetric with opening central axis；On jaw assembly 4
Domatic corresponding with on opening gear 2 of roller 403, jaw bolt 5 runs through screw and the jaw assembly 4 of on maxillary grillage 1
Through hole until the through hole of 3 on lower jaw grillage, jaw assembly 4 can rotate around jaw bolt 5, forms swing type jaw clamping machine
Structure；The intrados of maxillary grillage 1 and lower jaw grillage 3 is provided with the receiving cambered surface that can accommodate jaw assembly 4, makes on jaw assembly 4
The upper and lower high-order bit that adds of jaw 401 can retract as far as possible, it is ensured that opening size maximum when jaw assembly 4 is retracted；Maxillary grillage
4 and the inside of lower jaw grillage 3 also be provided with accommodating the holding tank of jaw assembly 4, make the roller 403 on jaw assembly 4 to use up
Retract possibly；By the centering of upper centering ring 6 between maxillary grillage 1 and opening gear 2, one end of upper centering ring 6 is by spiral shell
Nail 7 is fixed in the upper end arc groove of opening gear 2, in the righting arc groove that the other end extend on maxillary grillage 1；Lower jaw grillage 3
And by the centering of lower centering ring 8 between opening gear 2, one end of lower centering ring 8 is fixed on opening gear 2 by screw 7
In the arc groove of lower end, in the righting arc groove that the other end extend on lower jaw grillage 3.Block teeth 402 intrados in jaw assembly 4 is resistance to
The nonmetallic materials of mill, it is ensured that bigger frictional force and wearability；The nonmetallic materials that block teeth 402 use are asbestos, resistance to
Mill filler and the composite of phenolic resin manufacture, or the composite being fabricated by for asbestos and polyurethane, it is also possible to
For abrasive rubber.Block teeth 402 height is more than 200mm, to increase containment area；Roller 403 in each jaw assembly 4 is two
Individual, contact with domatic on opening gear 2 to increase, minimizing is to domatic extruding force, and provides the block teeth 402 increased and more have
Power supports.
When operation, opening gear 2 first rotates, and maxillary grillage 1 and lower jaw grillage 3 are braked, on band moving jaw plate assembly 4
The roller 403 domatic upward slope on opening gear 2, until after block teeth 402 hold tubing string tightly, maxillary grillage 1 and lower jaw grillage 3 drive
Jaw assembly 4 is held tubing string tightly and is realized upper button or shackle operation.Wherein using the clamping force that the offer of swing type jaw is bigger, employing adds
High block teeth 402 strengthen containment area to increase rubbing surface, use wear-resisting non-metallic composite material to increase frictional force to reach to need
The moment of torsion wanted.
