Abstract

PURPOSE: To obtain optimum vibration for objective ground and according to the purpose of construction work by a method in which vibrating shafts with eccentrical dead weight are provided in two stages in the same number for each and initial phase difference of the vibrating shafts between one stage and the other stage is varied by turning the vibrating shafts reversely or in the same direction with a revolving number.
CONSTITUTION: Upper and lower vibrating shafts 6 and 15 are geared with each other in such a way that eccentrical dead weights 7 and 7' are positioned at the lower end and a motor 2 is operated, whereupon the vibrating shaft 6 is turned in the direction of arrow (a) by the gear, the second driving shaft 8 is turned in the direction of arrow (b) (reversed direction) through the first driving shaft 4 and gear 11, and at the same time the vibrating shaft 15 is also turned at the same speed in the opposite direction to the vibrating shaft 6. Then, when a motor 18 is operated and a free moving drum 9 is turned in the direction of arrow (c), a free moving shaft 12 turns in the direction of arrow (d), and the lower vibrating shaft 15 is turned in the direction of arrow (b). Thus, by turning the free moving drum 9 at a proper angle, the phase difference between the vibrating shafts 6 and 15 can be properly set up. By varying the initial phase difference properly, the vibrating forces in vertical and distorted directions can be altered.
