Abstract
A hydraulic locking system of a steel dam gate relates to a locking device of the gate and comprises a starting arm. Two through holes are symmetrically arranged on the starting arm, an arc-shaped locking support is arranged in the starting arm in a penetrating mode, two ends of the arc-shaped locking support are respectively connected with a locking seat, and a plurality of hydraulic locking holes are arranged on the arc-shaped locking support. One side of the starting arm is connected with a hydraulic cylinder, and a flexible end of the hydraulic cylinder is connected with a locking rod which is detachably arranged in the two through holes and the corresponding hydraulic locking holes in penetrating mode. One side of the starting arm far away from the hydraulic cylinder is connected with a limiting controller connected with a control circuit of the hydraulic cylinder, two manual locking holes are symmetrically arranged on the starting arm, and a same manual locking pin is arranged in the two manual locking holes and the corresponding hydraulic locking holes in the penetrating mode. By means of the design, if a fixed angle of the gate is not opened and closed for a long time, users can manually complete double locking increased by a manual pin roll on the basis of hydraulic locking, and locking can be guaranteed to be safe and reliable.
Description
Technical field
The utility model relates to a kind of locking device of gate, relates in particular to the lock-in techniques field of steel dam anchor gate of the usefulness of Hydraulic and Hydro-Power Engineering, civic landscape, flood protection works.
Background technology
Gate run to need block the water height time; Under the situation of cutting off power; Should be able to rest on the desired location reliably and with long-term, though driving oil cylinder can adopt element such as hydraulic lock to lock, hydraulic locking is because the inside and outside leakage effect of oil cylinder; After cutting off power source, permanent locking is also unreliable.Existing publication 200920233108.X; Patent name is a kind of locking device of steel gate; Its structure comprises the connecting lever in the steel gate; It is characterized in that described locking device comprises that locking pole socket, locked cylinder, locked cylinder mount pad, locked cylinder piston rod front end are through the fixing stop pin of screw thread, the arc securing rod with some lock holes, locking travel switch and release travel switch; The arc securing rod passes the connecting lever middle part; Its two ends are hinged with the locking pole socket through bearing pin; The pin-and-hole center of locked cylinder in the middle part of the locked cylinder mount pad is fastened on connecting lever, the locking travel switch is fixed in the locking key seat of connecting lever another side, and the release travel switch is fixed on locked cylinder mount pad corresponding position; The external integrated hydraulic device of locked cylinder, locking travel switch, the external control electric installation of release travel switch signal.This latch-up structure is under the situation that gate extended immobilization angle does not does not open and close, and is safe and reliable not enough.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of prior art, a kind of hydraulic locking system that can guarantee the reliable steel dam anchor gate of locked secure to be provided.
The purpose of the utility model is achieved in that the hydraulic locking system of steel dam anchor gate; Comprise start arm; Be symmetrical set two through holes on the start arm; Place an arc lock bracket in the start arm, the two ends of arc lock bracket connect the locking seat respectively, and several hydraulic locking holes are set on the arc lock bracket; One side of said start arm connects hydraulic jack, and the flexible end of hydraulic jack connects securing rod, and securing rod is detachable to be set in two through holes and the corresponding hydraulic locking hole; Said start arm connects limit controller away from a side of hydraulic jack; Limit controller connects the control circuit of hydraulic jack; Also be symmetrical set two manual locking holes on the said start arm, in two manual locking holes and corresponding hydraulic locking hole, place same manual lock rationed marketing.
The utility model is provided with several hydraulic locking holes according to the locking requirement of any opening angle of gate on the arc lock bracket, the gate fluid pressure drive device drives the gate start arm; Make gate make arcuate movement to set angle; Cooperate electrical control equipment through hydraulic means, primer fluid compressing cylinder driven locking bar is when securing rod arrives limit controller; Spacing control is cut off the power supply automatically, accomplishes the locking of set angle.If gate is under the situation that the extended immobilization angle does not does not open and close, on the basis of hydraulic locking, can manually accomplish manual bearing pin increases Double Lock, guarantees that locked secure is reliable.The utility model locking system volume is little, simple in structure, easy to use, dependable performance, and cost of investment is low, can realize automatic control, mainly is applicable to water conservancy, water power and civic landscape, flood protection works, applied range.
