Control system and control method suitable for enabling inclined frame car of inclined ship lift to stably pass through hump

Abstract

The invention provides a control system and a control method suitable for enabling an inclined frame car of an inclined ship lift to stably pass through a hump. The control system comprises the inclined frame car, a steel wire rope, a steel wire rope reel, two hoist devices, two friction devices, a control unit, a detection device, two hoist electrical transmission devices and two friction electrical transmission devices, wherein the detection device is used for feeding back equipment operation data in real time; the control unit is used for controlling the two hoist electrical transmission devices and the two friction electrical transmission devices according to the control command and the signals fed back by the detection device; the two hoist electrical transmission devices are used for driving two hoist motors to work, and enabling the reel to operate by a speed reducer so as to wind and release the steel wire rope, thus driving the inclined frame car to run on a track; when the inclined frame car passes through the hump, the two friction electrical transmission devices are used for driving two friction motors to work so as to enable two friction wheels to operate, so that the inclined frame car is driven to run by the coordination and combined action of the two hoist devices at the flat section of the hump and can continuously and stably pass through the flat section of the hump. The control system and the control method are simple in principle, convenient to implement and low in cost, are mainly convenient in connection with an automatic system, are incorporated in the automated process and enable the inclined frame car to stably pass through the hump automatically and reliably.

Description

technical field [0001] The invention relates to a control system and a control method for a longitudinal double-slope ship lift to climb over a hump. Background technique [0002] The ship lift is a kind of navigable structure that uses mechanical methods to lift ships. It is used to overcome the concentrated water level drop in the channel and lift or lower the ship from one water level river section to another water level river section. [0003] The basic components of a ship lift include: a ship-carrying box (or a ship-carrying frame or a ship-carrying car), which is used to park a ship; a vertical frame or a ramp, the former is the supporting and guiding equipment of the vertical ship The operation of the inclined ship lift; it is connected to the building, and it is set at the connection between the upstream and downstream approach channels and the ship-holding box, so that the ship's self-supporting ship box enters the approach channel or the ship's self-guiding channe...

Problems solved by technology

[0007] The friction drive device is used to cross the hump. In the past, DC drive was used, which was manually operated, with low automation, high labor intensity and poor reliability. The operation can only be performed by the experience of the operator; , automatic control, when running over the hump, the impact is large, and the effect is not good

Moreover, the inclined frame truck has two working conditions of dry transportation and wet transportation. If the operation is not stable, especially when the inclined frame vehicle passes the hump, it is required that the inclined frame vehicle should keep running at a constant speed, so that the ships in the inclined frame vehicle will not be damaged. If the position is moved, if the operation is not stable, the boat carried in the inclined frame will move, which will cause damage to the equipment and injury to the personnel on board in serious cases, affecting the safety of operation
