Description
Technical field
The present invention relates to the technical field of crane equipment of dam, more particularly to a kind of gate segmentation headstock gear and its keying
Method.
Background technology
With being continuously increased for hydroelectric project gate opening/closing lift and capacity, the volume of high-lift Large Copacity headstock gear and again
Amount also increases therewith, while is influenceed by gate recess arrangement, it will the further reel of increase opening and closing device, decelerator, system
The specification and size of the parts such as dynamic device, motor power (output), frame, cost can also be significantly increased；Operating mode is opened and closed with dynamic water
High-lift force of opening and closing is by hydraulic pressure（Aperture scope）Influence greatly, exemplified by opening door, opening and closing priming stroke section（Aperture scope
It is interior）By hydraulic pressure and hydraulic action, a power maximum is opened；Conversely, it is also in lowermost to close door（In the range of aperture）By hydraulic pressure and waterpower
Effect, lasting force are maximum；At present, the hoisting capacity of gate hoist is determined with the big value in both, beyond the scope of aperture,
Hoisting capacity is only decided by gate weight and running resistance, and its value is much smaller than the hoisting capacity of aperture scope；There is water to open and close operating mode
High-lift gate hoist, Load Characteristics are from aperture top to the interior in a big way of lintel position, and hoisting capacity is mainly gate
Weight and operation frictional resistance, its numerical value is smaller, and in the range of the aperture from lintel to ground sill, hoisting capacity is mainly big water pressure
Lower suction and gate weight caused by caused running resistance, current, its numerical value is far above hoisting capacity more than lintel；For this
Kind has the Load Characteristics of feature very much, and lifting mechanism can be optimized.
In the prior art, such as Publication No. CN204549854U, the time of disclosure is August in 2015 12, entitled " a kind of
The Chinese utility model patent document of crane hoisting mechanism and electric-control system ", disclose a kind of crane hoisting mechanism and electricity
Control system.Lifting mechanism, including two sets of winding drum lifting mechanisms, two sets of auxiliary anti-swing mechanisms；Winding drum lifting mechanism includes raising electricity
Machine, reduction box, have more rope reel and the raising line being connected with suspender, and the output end of lifting motor and the input shaft of reduction box connect
Connect, have more rope reel device on the output shaft of reduction box, raising line, which is wrapped in, to be had more on rope reel；Auxiliary anti-swing mechanism includes
Assisted deceleration arrestment mechanism, coaster, push rod, auxiliary drum and the auxiliary rope being connected with suspender, assisted deceleration arrestment mechanism are set
On coaster, push rod connection assisted deceleration arrestment mechanism, auxiliary drum is arranged on assisted deceleration arrestment mechanism, auxiliary rope winding
On rope reel and auxiliary drum is had more, but the lifting force of two sets of lifting mechanisms of this technical scheme is separate, is using
It is unfavorable for the force equilibrium of lifting force during to gate opening, door opening state is unstable, can not optimize structure and cost.
The content of the invention
It is an object of the invention to provide a kind of driving of double raisings of different using raising specification but public hawser, suspender etc.
Mechanism, different lifts/opening for the discrepant gate of hoisting capacity that aperture needs/can be directed in the opening/close of dam sluice gate and are closed,
Corresponding headstock gear has the headstock gear of the gate segmentation keying of different hoisting capacities in corresponding lift/elevation.

Set at the middle part of reel；
(5) electric control system presses lift（Stroke）The lifting mechanism to put into operation is set, realizes that two suspension centre work coordinations are consistent,
Two sets of lifting mechanism operations have continuous operation automatic switchover and interlock function.
Understood by motor power P=F*V (wherein, F- is hoisting capacity, and V- is the speed of service, does not consider efficiency), fortune
The row time low capacity raising drive mechanism power of motor of length can be greatly lowered, and can optimize Large Copacity raising using this method
The drum diameter and decelerator specification of drive mechanism, optimize motor, decelerator, brake and the volume of low capacity raising drive mechanism
Cylinder, the overall Load Characteristics for more meeting such operating condition.
