EXCITATION FORCE CONTROL METHOD OF DEVIATED HEAVY BOB AND EXCITATION FORCE CONTROL DEVICE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a control method and a control device capable of upgrading a deviated heavy bob type exciter for civil engineering construction work and increasing and decreasing arbitrarily the excitation force under control in continuous mode without interrupting the operation of the machine and constituting the whole of the exciter is being in small size and light weight and further reducing noises greatly. ;SOLUTION: A phase control gear A24A engaged with either a fixed deviated heavy bobs 20A and 20B fixed with a pair of fixed deviated heavy bobs 9A and 9B respectively is interconnected to a phase control gear B24B engaged with either movable deviated heavy bob gear 22A and 22B fixed with a pair of movable deviated heavy bobs 10A and 10B respectively by way of fluid type reversible rotary mechanism 17, (for example, hydraulic rocking motor) and a clutch means 16.;COPYRIGHT: (C)1997,JPO
