Description

The toggle of hydraulic engineering hydraulic pressure dam three opens and closes support meanss

Technical field

The utility model is related to hydraulic engineering technical field, and specially a kind of toggle of hydraulic engineering hydraulic pressure dam three opens and closes support Device.

Background technology

Rationally to utilize water conservancy hydraulic power potentials, dam is built on river,lake and reservior and sets lock dash, to improve water level, for farmland irrigating Irrigate, hydroelectric generation, domestic water and landscape retaining；During flood, movable dam can quickly open a sluice gate flood discharge, and water level is reduced in time, keep away Exempt from big flood.Current river and sluice engineering is more, gate opening/closing support Various Types of Dams, but Normal hydraulic dam is in engineering actual motion In there is problems with：

（1）Aesthetic problem：Normal hydraulic dam gate lays four road bars behind the door per fan brake（Twice hydraulic stem, two Road support bar）, too much, this kind of engineering design largely build scenic spot in, it is necessary to reference to landscape requirement, if door back of the body branch to door back of the body rod member Bar is too many, it appears in disorder, influences attractive in appearance；

（2）Oil cylinder and door carry on the back pole by flood and influence to sediment problem：Door back of the body pole will stretch out much when gate is droped to the ground, By current and stone impact, pole easily is damaged, there is potential safety hazard；And the support of hydraulic pressure dam and gate hoist cylinder exist Oil cylinder foundation ditch and pole lock slots are set on bottom plate, is immersed in the foundation ditch of below ground, is easily influenceed by flood and silt（Silt Alluvial）, the safety and reliability of influence gate operation；

（3）Gate any angle operation problem：It is only capable of during existing gate support in 75 ° of supports, other angles are by hydraulic stem It can not be locked during support, and stand up must accurately in place for gate, and pole could lock, if subjected to current and influence to sediment, It is difficult to its accuracy in place；

（4）The problem of operating maintenance：Existing equipment is laid in pit, by current, silt, frost factor influenceed compared with Greatly, inconvenience is brought to operational management, maintenance.

The content of the invention

There is aesthetic problem in engineering actual motion, easily by by flood to solve existing Normal hydraulic dam in the utility model The problems such as water and influence to sediment problem and gate any angle operation problem, operating maintenance, there is provided a kind of hydraulic engineering hydraulic pressure The toggle of dam three opens and closes support meanss.

The utility model adopts the following technical scheme that realization：The toggle of hydraulic engineering hydraulic pressure dam three opens and closes support meanss, Including gate installation seat and pole mounting seat, gate sheet is hinged with by rotary shaft on gate installation seat, it is characterized in that gate is pacified Dress seat and pole mounting seat interval are fixed on ground, and gate installation seat inner side is installed in gate hoist cylinder, pole mounting seat Portion is hinged with lower fulcrum bar, and gate back is hinged with upper rack posts, piston rod, lower fulcrum bar and the upper rack posts of gate hoist cylinder with Three toggle components are connected；The three toggles component includes three toggle bodies, and three toggle bodies are down through hinged-support and rotary shaft Swing pinion is symmetrically installed with, three toggle body interiors are provided with by fixing axle can be while that is engaged with two swing pinions be flat Move gear；Three toggle body sides are connected with the piston rod of gate hoist cylinder, and opposite side is arranged with locking hydraulic jack, lock The piston rod for determining hydraulic jack is connected with shiftable gear, and two swing pinions are connected with upper rack posts, lower fulcrum bar respectively.

Using structure design of the present utility model, gate installation seat and pole mounting seat are set on the ground, in hydraulic brake The place that the upper and lower pole of door and gate hoist cylinder can be handed over sets three toggle components, and the three toggles component is that regulating gate rises and retires Operation and the important component of locking, in gate opening or closing, by gate hoist cylinder by three toggle component integral jackings Or retract, gate is realized under the linkage effect of upper and lower pole and corresponding swing pinion and is turned on and off；And when gate stops fortune OK, and need when any angle is locked, by lock hydraulic jack control shiftable gear move horizontally so that put down Move gear to engage simultaneously with two swing pinions, then upper and lower pole is fixed, reach the purpose of locking gate.

In order to further optimize the structure of the keying support meanss, its function is improved, the utility model has also carried out following Improve：

The upper rack posts, lower fulcrum bar are the split-type structural being made up of upper semisection and lower semisection, upper semisection and lower semisection Joint be set in together by tune mouthful bolt thread of the two ends with fixing nut, wherein hung at the top of upper semisection provided with pole Welded with swing pinion ear, lower semisection end.Upper and lower pole uses the structure type, and itself can carry out the regulation of length, be easy to Adjust three toggle components in gate opening or closing and gate relative position.

The shiftable gear is located at the center of two swing pinions, and close to gate hoist cylinder piston rod one Side.

The fixing axle two ends are set up on three toggle body two sides, and three toggle body two side relevant positions open up cunning Move elongated hole.In the presence of locking hydraulic jack, fixing axle can be forced to be moved forward and backward along sliding elongated hole, so that shiftable gear It is engaged or is departed from two swing pinion.

Compared with prior art, the utility model has advantages below：

1）It is attractive in appearance：Four road bars are changed to twice bar to gate behind, and gate pole and oil cylinder elevating lever pass through " three toggle components " Two bars is united two into one, so both simplify door body structure, take on a new look again, clean and tidy gate profile；

2）Not by oil cylinder by flood and influence to sediment：Below ground does not set oil cylinder foundation ditch and pole lock slots, not by flood With the influence of silt, the safety and reliability of gate operation is improved；

3）Solve gate any angle operation problem：Lock can be solved by two swing pinions and a shiftable gear The locking of door any angle and slant operation；

4）The problem of solving operating maintenance：Below ground does not set oil cylinder foundation ditch and pole lock slots, is easy to repair and manages Reason.

In a word, the utility model have the advantages that simple in construction, dam facing it is clean and tidy, by external environment influence, largely carry The high flexibility of gate operation, once it will be a new technology raising again to implement that hydraulic pressure dam will be studied, can change existing hydraulic pressure Dam operation conditions, can improve the social benefit of hydraulic engineering and the economic benefit of engineering.
