Consult Figure 11, Figure 11 be the utility model silent piling captain ship with short ship can relative movable ability and displacement situation key diagram, it can be divided into three kinds of situations simply, promptly move forward and backward, move left and right and transfer are moved, among the figure with the long ship of long narrow square representative, with the short ship of short rectangle representative, every static pile press includes two long ships and two short ships, and every kind of situation has all provided vertical view and lateral plan among the figure, is illustrated by clear in the drawings.Existing division is as follows:
The length ship moves forward and backward relatively: its moving method is distinguished, it utilizes the long ship of oil pressure 14 elder generations rise to make long ship liftoff, promoting long ship with oil pressure 6-1 again moves forward long ship aloft, when arriving the end or preset distance, long ship is fallen, be raised liftoff until short ship, then short ship is shifted to the place ahead, after arriving the end or preset distance short ship is put down, and, reach the purpose that moves forward and backward by these actions of continuous circulation again the raise difference of the method that moves forward of long ship.This move mode and traditional pile driver also have very big difference.
Relative move left and right: about the method that keeps straight in the back in front of the method walked crosswise just the same.
Move relative to transfer: in response to the ground type and the different of position, position of driving piles, in order to satisfy the needs of various kinds, this machine not only can move left on the right side, front and back, more can the oneself turn to required angle.Though its each amplitude of rotating is 8 degree, can satisfy the needs of most of engineering.
Because long ship and short ship can relatively move, and the scope of application of this pile press is widened greatly.
Move and the cooperation of lifting by structure and oil pressure of the utility model pile press realize, oil pressure 14 rises that comprise the 3rd group of elevating oil cylinder make long ship built on stilts, after the oil pressure 6-1 by the 4th group of longitudinal oil cylinder pressure pushed away preceding or returned this moment, can reach and move forward and backward; Rise short ship built on stilts before correspondingly pushing away by after being located at the 5th group of oil pressure 78 in the short ship and pushing away preceding or returning by the 3rd group of oil pressure 14, can reach left and right moves, but rise short ship by aforesaid step and pass through ad hoc meta pilot pin corner swing, the 5th group of oil pressure 78 left and right sides different aspects of the short ship of the lifting of the long ship of cooperation and front and back push away and draw, but reach gyration.
