Relay driving type electrical control device of inclined ship lift

The invention discloses a relay driving type electrical control device of an inclined ship lift. The relay driving type electrical control device of the inclined ship lift comprises a winch master transmission unit, a winch slave transmission unit, a friction wheel master transmission unit, a friction wheel slave transmission unit, a PLC (Programmable Logic Controller) and four position switches, wherein the PLC comprises a winch speed detection module, a friction wheel speed detection module, a control signal module and a ship reception chamber position detection module; the winch speed detection module is connected with the winch master transmission unit, the winch master transmission unit is connected with the winch slave transmission unit, the friction wheel speed detection module is connected with the friction wheel master transmission unit, the friction wheel master transmission unit is connected with the friction wheel slave transmission unit, the control signal module is connected with the winch master transmission unit, the friction wheel master transmission unit and the friction wheel slave transmission unit, and the ship reception chamber position detection module is connected with all position switches. The relay driving type electrical control device can solve the problem that the winch of the inclined ship lift is in close relay driving cooperation with a friction wheel, enables a ship reception chamber to stably cross a hump, can ensure safe operation of the inclined ship lift, and can be widely applied to the inclined ship lift.
