Its weak point is: 1, locked cylinder axially parallel is in lower shaft, and for the ease of placing locked cylinder, hoist chamber's width dimensions of design is larger, has increased the cost of auxiliary civil engineering; While 2, debugging at the scene, because gate flap is subject to the impact of hydraulic pressure after erecting, erecting angle and must producing error of gate flap, causes the position degree of lock hole to be offset, and the piston rod of locked cylinder is difficult to be inserted in lock hole.
Utility model content
The purpose of this utility model is to provide a kind of connecting lever locking mechanism of steel dam anchor gate, makes the mode of its locking simple and reliable, is convenient to installment and debugging, has reduced the width of hoist chamber.
The purpose of this utility model is achieved in that a kind of connecting lever locking mechanism of steel dam anchor gate, comprise and be arranged in hoist chamber and be hinged on the headstock gear oil cylinder on oil cylinder free bearing, piston rod external part and connecting lever one end of headstock gear oil cylinder are hinged, the other end and the lower shaft of connecting lever fix, lower shaft is arranged in lower shaft free bearing rotationally, on lower shaft, be provided with gate flap, in described hoist chamber, be provided with locking mechanism, described locking mechanism comprises lockplate and stop pin, described lockplate is fixedly connected on connecting lever, on lockplate with lock hole; The surface of revolution at the axis of stop pin and connecting lever center is positioned at same plane, and stop pin is connected on straight line driving mechanism; At gate flap when needing latched position, the axis of stop pin just with the position of lock hole over against also inserting in lock hole.
During this device work, by headstock gear hydraulic oil cylinder driving connecting lever, rotate, connecting lever drives gate flap to rotate through lower shaft, when gate flap erects, realizes and blocks water, and when gate flap fell, realization discharges water; When the position of gate flap in need lockings, for example, when gate flap erects, can drive stop pin to insert in lock hole by locked cylinder, gate flap is locked in to the position erecting, now, and the load of the detachable cylinder that deoils, headstock gear oil cylinder can quit work.Compared with prior art, the utility model is simple in structure, saves space, make the width of hoist chamber can build narrowlyer, structure is compacter, reduces the cost of auxiliary civil engineering, also the difficulty that has reduced workman's installment and debugging, has facilitated patrol officer's walking simultaneously.
Above-mentioned straight line driving mechanism can be locked cylinder or screw mandrel drive mechanism.Both all can stretch out and retract by linear drives stop pin, all have enough large motive force, can guarantee connecting lever locking and convenient for unlocking.
As a kind of improvement of the present utility model, between lockplate and connecting lever, be provided with stiffener.This structure has increased the rigidity being connected between lockplate and connecting lever, increases the service life.
As another kind of improvement of the present utility model, stop pin movable set is on location-plate, and location-plate is fixedly connected on the concrete positioning seat arranging in hoist chamber.After connecting lever locking, can bear by location-plate the lateral force of stop pin, the quality of fit while guaranteeing stop pin and location-plate, guarantee that oil cylinder is not subject to lateral force, make its use more reliable.
Location-plate is arranged with two in parallel, and the advantage of this structure is to improve the positioning precision of stop pin.
Between stop pin axis and horizontal plane, be 30 ~ 60 degree angle settings, the advantage of this structure is to facilitate site operation and debugging.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
