In some moment, four driver elements have different phase places (as shown in figure 12)； Four driver elements share a main shaft 510 and cooperate, it can be ensured that main shaft 510 continues defeated Go out power.

After the installation of this device, the work of the rotating turret 51 of its at least one driver element Moved end is vacant state, for the initial kinetic energy of this above-mentioned main shaft 510 from driving in vacant state Moving cell, and then drive main shaft 510 to rotate acquisition initial kinetic energy.

During shutdown, only need to stir the clutch plate 513 of one of them driver element, make clutch plate 513 On locating dowel 514 exit the hole, location 512 of drive sprocket 511, just can realize this driving list The time-out of unit.

Situation in clockwise oscillation is raised for swing span 10 left side, with above-mentioned operation principle Unanimously, here is omitted.

It addition, except aforementioned four driver element, an idle swing span 10 also can be arranged With the driver element of the right and left, it is used for substituting other driver element and shuts down when needs overhaul, And make whole table apparatus continue to run with.Concrete implementation mode is by the idle swing span of regulation The rotating shaft of the driven sprocket of two driver elements so that it is the angle of cam 63 and the swing of time-out The phase place of two driver elements of frame 10 keeps consistent.But, drive this swing span 10 On driver element, driver element to be repaired and swing span can be stopped, can be as newly after maintenance Idle driver element, for replacing new fault driver element.

In sum, the present invention utilizes pressure assembly 50 to act on suspension 40, passes through This active force is transferred to swing span 10 by stay cord 30, finally by ratchet mechanism 54 by moment Putting on main shaft 510, provide the power rotated for main shaft 510, it may be implemented in without other Power or other power less in the case of, make main shaft 510 rotate constantly, thus output turn Dynamic power, therefore, the present invention can reduce coal, gasoline, the consumption of natural gas equal energy source, And will not discharge harmful, minimizing environmental pollution in atmospheric environment.
