Embodiment Construction
[0053] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, but these embodiments should not be construed as limiting the present invention.
[0054] see figure 1 , take the inclined plane ship lift ship-bearing box 55 to run from upstream to downstream (abbreviation: the ship-bearing box 55 descends) as an example, on the upstream ramp, it is driven by the winch, and the steel wire rope 52 bypasses the fixed pulleys 49, 50 to pull the ship-bearing box 55 Slope run.
[0055] When the bumper 48 bumped into the fourth position switch 47, the friction wheel 54 started, and the ship compartment 55 continued to run uphill, and the friction track 53 began to contact the friction wheel 54, and the ship compartment 55 was jointly driven by the hoist and the friction wheel 54.
[0056] When the bumper 48 bumped into the second position switch 45, the winch decelerated, and the ship-holding compartment 55 was dr...

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.
Description
technical field [0001] The invention relates to an electrical control system for a relay drive of an inclined ship lift, in particular to an electrical control device for a relay drive of an inclined ship lift. Background technique [0002] The inclined ship lift generally adopts the form of launching the ship-holding box. Compared with the vertical ship lift, it does not need to set the upper and lower lock heads, which can greatly reduce the amount of earth and rock excavation and concrete pouring, and save engineering investment. At present, most of the inclined ship lifts built in my country are small. [0003] There are several ways to pass the hump of the ship-carrying box of the inclined ship lift: using the running inertia of the ship-carrying car to pass the hump, using the hydraulic pusher to push the hump, and using the friction wheel to drive the hump (abbreviation: rubbing the hump) and so on. . The small inclined ship lift generally adopts the way that the sh...
