Description
Technical field
The utility model is related to water power hydraulic engineering field, more particularly to a kind of projecting push mode gate.
Background technology
With the development of the city, requirement of the people to living environment is improved constantly.Water environment in urban construction is forged into
To lift the most important thing of living environment.Accordingly also got a promotion around the supporting landscape effect of water environment.And gate is used as water
Environment makes important equipment in facility, and whether its structure type is warm with integrated environment concept, directly influences the whole of project
Body effect.The gate major function of urban landscape is to improve riverbed water level to maintain to be led off during the landscape water surface, flood
Flood, on draining off floodwater, influence is small.Major requirement to such gate has：Exposed equipment is few, take up an area less, maintenance is convenient and needs
It is warm with surrounding enviroment good.Such gate is high without obvious weir, and in check flood water level, upstream and downstream water level difference is typically small,
Therefore it is unfavorable for arranging gates of segmental shape.And most of gate requirement dam facings are without operation equipment building, subsequently to enter to do business
Industry is developed or other landscapes are made.At present, meet the gate of the feature mainly have under hydraulic pushing gate, lower shaft crouch gate and on
Turn over gate.Wherein, the gate that crouched under lower shaft is driven using lower shaft or both sides motion arm drives, and this force structure determines that gate keeps off
Water height can not possibly be very high, and gate height increases all influences very big to gate structure and headstock gear；To be accounted for rotate simultaneously after
There is very big horizontal space, it will increase lock chamber length.On turn over gate and be equally suitable only for the less sluice of head, gate turns to water
Prosposition will increase lock chamber length.Hydraulic pushing gate be with the hydraulic pushing oil cylinder being embedded in gate pier operated it is vertical
Lifting plane gate, the landscape sluice larger for gear water storage level, selection hydraulic pushing gate is most suitable, and not only top can
Setting low discharge overflow increases landscape effect, and bottom also helps regular sand surfing sand discharge.
But during for normal pool level and larger flood level difference, its sluice dam crest differs larger with normal pool level,
Even if using hydraulic pushing gate also more difficult arrangement relevant device.As shown in accompanying drawing 5 and accompanying drawing 6, due to normal water storage level
Differed greatly with check flood water level, therefore the end face of the gate pier of both sides will be far below in normal retaining, at the top of lock gate leaf,
And in flood discharge, then require completely to lift gate flap, flood discharge flow is ensured with starting gate to greatest extent.Now when using liquid
Bear down on one when pushing away gate scheme, it is necessary in lock gate leaf both sides arrangement hanger not only high but also big, not only increase wind load, and pushing tow
The stressing conditions of oil cylinder will be greatly increased, while also requiring that the ejection amount of pipe bending cylinder is more long；And with the oil of ejection amount more long
During cylinder, when oil cylinder ejection is higher, its stressing conditions is also highly unstable, therefore requirement to oil cylinder performance is also very high, will
Cause sharply increasing for oil cylinder cost of investment.

The hollow-core construction inside steel pipe plunger rod 81 is connected with the hollow-core construction in piston rod 91 by connecting line 11 again afterwards, specifically
Can refer to shown in accompanying drawing 3.By said structure, it is only necessary to which, by outside oil-servicing facilities, such as hydraulic oil pump is supplied to hydraulic oil
Oil pipe line 10 feeds hydraulic oil, you can makes the jacking of steel pipe plunger rod 81, and shrinks piston rod 91, is to be capable of achieving opposite house with this
The lifting operation of leaf 1；Otherwise when draining, can decline steel pipe plunger rod 81, and make piston rod by the self gravitation of gate flap 1
91 elongations, the lowering operation to gate flap 1 can be realized with this.More specifically, can be also provided with hydraulic oil oil feed line 10 flat
Weighing apparatus valve 7, wherein it is preferred that using the balanced valve 7 with lock function；Gate flap 1 so can be indirectly controlled by controlling balanced valve 7
Open amount；Especially in draining, can be controlled under gate flap 1 high-volume and lowering velocity by controlling balanced valve 7.
In addition, lift by crane gate flap 1 during, it usually needs first by the jacking of crossbeam 3 to certain height after, could lead to again
Shift mechanism is crossed further gate flap 1 is sling.Therefore, in the operating process of lifting gate flap 1, should as far as possible first by top-pushing mechanism
Ejection crossbeam 3, then again by hanging drawing mechanism overhung door leaf 1；Conversely, in the operating process of decentralization gate flap 1, then should be as far as possible
First pass through and hang the decentralization gate flap 1 of drawing mechanism 3, crossbeam 3 is then being transferred by top-pushing mechanism.More specifically, in order to realize above-mentioned effect
Really, when first hydraulic jack 8 and the second hydraulic jack 9 of series connection is provided with, under identical oil pressure conditions, second can be chosen
The hoisting capacity of hydraulic jack 9 is less than the hoisting capacity of the first hydraulic jack 8 to realize above-mentioned purpose.The second hydraulic jack such as can be set
9 oil pressure areas are 0.8 times or so of the oil pressure area of the first hydraulic jack 8, so, due in the first hydraulic jack 8 and two
Oil pressure in two hydraulic jacks 9 is equal, therefore the hoisting capacity of the second hydraulic jack 9 will be generally the keying of the first hydraulic jack 8
0.8 times of power, can realize first making the jacking of steel pipe plunger rod 81 in the first hydraulic jack 8 with this, be risen with ejection crossbeam 3, until
When the jacking amount of steel pipe plunger rod 81 reaches its stroke maximum, excess portion component is born by cylinder body, the second just meeting of hydraulic jack 9
Start to shrink at action.Conversely, be then that piston rod 91 first extends when draining, until the elongation of piston rod 91 reaches its stroke
Maximum when, the first hydraulic jack 8 can just begin to decline action.
