Description
Technical field
The present invention relates to Mechanical course field more particularly to a kind of main promotion braking systems of the full balanced vertical ship lift of winding type
System,
Background technique
The wet full balance rope hoisting formula vertical ship lifts of fortune of 2 × 500t grades of Shuikou Hydraulic Station boat, are China first
Seat designed, designed, manufacture, construction and installation full-balance vertical ship lift, boat is pinged with inside after debugging in April, 2003
Success, in November, 2003 by final acceptance of construction, formally externally ping boat in April, 2005.Mouth of a river ship lift is gone through from operation is designed into
It through time more than ten years, is proved from the operative practice of many years, some equipment often expose the defect in design, and palpus improvement is some
Device product starts aging, must update and technological transformation.The ship compartment of wirerope winding type ship lift by wire rope suspensioning, and
It is driven by main hoist system, makees vertical lift operation in the ship compartment room between ship lift king-post.
Mouth of a river ship lift main equipment room is equipped with the main promotion braking system equipment of ship lift, main function: first is that being used for ship compartment
When running accurate off-position up and down, guarantee the stability in ship compartment；Second is that can make 2 × 5500 tons big used when ship lift breaks down
Amount system can smoothly stop, and be the important equipment of full balance elevator vertical ship lift safe operation, can to the safety of system
It is more demanding by property.Since ship lift puts into operation, braking system operational reliability is poor, to the security reliability of ship elevator
It influences very big.
According to ship elevator program, ship compartment need to detect ship compartment levelness deviation, work as level before normal lifting operation
When spending deviation greater than 10cm, ship compartment should first be leveled, and ship compartment levelness deviation is adjusted to design permissible value.Since original is made
The main hoisting drum deadman's brake and controllable reel deadman's brake of dynamic system share a set of control valve group, and the two cannot be distinguished
Control, when ship compartment levels, whole deadman's brakes are damped condition, and ship compartment stress is made to be in longitudinal every side four-point lifting bearing
Indeterminate state levels process, not only makes ship compartment discontinuity, also greatly increases ship compartment leveling difficulty.It brakes and imitates from accident
Fruit considers that original design is implemented by deadman's brake, but through field adjustable, since deadman's brake quantity is more, brake synchronous
Difference, practical service brake of having used instead is implemented by stepped voltage regulation accident control for brake, therefore service brake assumes responsibility for a liter ship
The normal operation parking brake and accident emergency braking task, reliability of machine directly affect the safe operation of ship lift.At present
