Principle of work of the present utility model is: thruster applies transverse force (P), this transverse force acts on the wedge block with two inclined planes, rely on stressed transmission, last voussoir just can produce ejecting force (F) at double, and the size of this ejecting force is decided by the size of thrust and the angle of wedge size α (being the inclined-plane of voussoir and the angle between the horizontal surface) of voussoir: can be got by Fig. 2
N＝P/(2sinα) (2)
Can get by Fig. 3 again
F＝Ncosα (3)
Comprehensive above-mentioned two formulas obtain at last
F＝P/(2tgα) (4)
If get tg α=0.05 then have
F＝10P
Therefore vertical ejecting force is ten times of horizontal thrust when tg α=0.05.
The beneficial effects of the utility model are: 1. the utility model utilizes the amplification of voussoir to power, reaches the purpose that obtains the super large ejecting force.2. when using thruster is laterally placed, then the utility model is specially adapted to work under the condition of narrow and small gap space.
