Description
Technical field
The utility model relates to the locking device of large hydropower station or pumped storage power plant self-action gate.
Background technology
Large-scale or heavy gate in actual motion, the normal time is in the inactive state of unlatching.For unsettled gate, though there is brake to control, during brake troubles, gate can be out of control, freely glides; In addition, gate is unsettled has long-time load effect to wire rope, adds the fatigue strength of wire rope, is more than serious potential safety hazard.In order to ensure gate safe operation, locking device need be installed, lock when gate does not open and close.
Utility model content
For solving the problem, the utility model provides a kind of automatic valve locking device, can ensure that gate is used safely.
Concrete solution is: a kind of automatic valve locking device, it is characterized in that, comprise securing rod, balancing weight, axle, axle sleeve and locking bearing, described securing rod and balancing weight are fixed on axle sleeve, described axle sleeve is sheathed on axle, axle is fixed in concrete foundation by locking base, and gate locating has the lock slots matched with locking device, the free position of using when keyed end when described lock slots is provided with gate lock and gate unlock.
Further, described locking device is positioned at gate bilateral symmetry and arranges, gate is respectively arranged with the lock slots corresponding with locking device.
Further, described locking bearing is fixedly connected with concrete foundation by pre-embedded bolt.
Further, described securing rod becomes 150 ° of angles with balancing weight.
Further, described concrete foundation is provided with the counterweight tank arbitrarily swung for balancing weight.
Beneficial effect: the present invention does not need manual operation, avoids the danger of manual work, accurately can carry out gate lock operation again simultaneously; Novel structure, reasonable in design, operating gate is flexible, the locking of large hydropower station or pumped storage power plant self-action gate.
Accompanying drawing explanation
Fig. 1 is automatic valve locking device lock-out state schematic diagram;
Fig. 2 is automatic valve locking device free state schematic diagram;
In figure, 1-securing rod; 2-balancing weight; 3-axle; 4-axle sleeve; 5-locks bearing; 6-concrete foundation; 7-gate; 8-lock slots; 81-locking bit; 82 free positions-; 9-counterweight tank.
Detailed description of the invention
When gate needs locking, gate is mentioned by headstock gear, now locking is in free state, drive securing rod to sway in gate uphill process, when the keyed end place of gate rises to higher than securing rod top, securing rod due to antimeric gravitational moment substantially equal, securing rod swings back between keyed end and free position, now gate falls, and securing rod can hold out against in keyed end place, by gate lock.
When gate needs unblock to transfer, can first be mentioned by gate (being greater than 200mm), until position, free position is higher than securing rod top, under gravity, securing rod can affranchise rotation, and at this moment gate can free releasing, and this is gate releasing process.
