Abstract

PURPOSE:To reduce the amount of electric current flowing at the startup by a method in which the elevating pinion of a working base ship is connected with a motor through a mobile cam in such a way as to burden loads thereto after the startup of the motor. CONSTITUTION:A working platform ship is vertically moved by driving a rack 5 attached to pipes forming legs by the pinions 6 of 6 elevators having drive motors 16. When driving the elevators, the mobile cams plates 18 of each elavator are set at each given position and then the first motor 16 is driven. By this, the mobile cam plates 18 are turned through a rotary cylinder 15, after the lapse of a given time the clutch claws 18a of the mobile cam plates 18 are coupled with the clutch claws 11a of clutch plates 11, and the rotation of the motors is transmitted to a drive gear 19. When the first motor 16 is actuated, the next motor is orderly actuated, and at a time when the 6th motor 16 is actuated completely, six pinions 6 are turned simultaneously.

As described below, according to the lifting device for a work barge of the present invention,
The lifting pinion of the work barge and the electric motor are interlocked and connected via a moving cam plate, and the load is applied after the electric motor is started, so less current flows during startup.
Therefore, the power supply capacity and wiring capacity for raising and lowering the work barge are small, which is economical. In addition, when a large number of lifting devices are required, it is possible to start the electric motors separately by simply adjusting the moving distance of each moving cam plate, and to apply a load to all wtwJ machines at the same time. ), the effect described above becomes even more pronounced.
