Problems solved by technology

[0007] As mentioned above, using the original load body driving device, in the case of emergency or maintenance, the main shaft is rotated and driven by the manual handle, and the waterway is opened and closed through the gate or valve. If the manual handle is operated due to curiosity or mischief, accidents may occur unknowingly to the load drive device.

Abstract

The present load body driving device efficiently operates a load body vertically and provides a clutch lowering by its self-weight of the load body in a part where torque is small. This load body driving device has load bodies provided on the channels such as weir plates, valves and strobes and so on, an output driving shaft for vertically driving a spindle to which the load body is attached through a power transmission device, a manually operated handle driven by and connected with a manually operated driving shaft in a manually operated driving system connected with the output driving shaft through the first clutch, a screw brake constituting a self-lock mechanism assembled into the manually operated driving system, a motor connected with the output driving shaft through the second clutch, and a lock mechanism capable of operating a locking piece provided in the manually operated handle so as to engage it with or disengage it from an engaging part provided in a housing of the female screw brake to rotate or lock the manually operated handle.

Description

technical field [0001] The present invention relates to a load body driving device, which is a power transmission device for moving up and down the main shaft supporting the load body in order to move up and down load bodies such as gates, gate bodies, weir plates, valves, etc. A manual drive system and an electric drive system are installed on it. Background technique [0002] In the past, load bodies such as weir plates, gates, and valves for opening and closing waterways and controlling flow were installed on waterways, waterworks, power plants, and rivers. In order to operate a load installed on a waterway, an operating device for driving a valve, that is, a load drive device can be used. The load body driving device used to operate the valve is developing towards the central information system for control by the controller. At the same time, a controller that can easily control the opening and closing of the valve is provided. For example, it is known in JP-A-11 - Con...
