Description
Technical field
The utility model is a kind of lifting structure, refers to an a kind of anti-lifting locking device that floods with higher-security especially.
Background technology
Along with China's rapid development of economy, track traffic, tunnel traffic have also been set foot on the road of high speed development, and track traffic and tunnel traffic are often wanted river crossing or lake, in case flood also being applied in track traffic and the tunnel traffic more and more widely of door.When operation is prevented flooding a rising or is descended, generally it is spurred by hydraulic action, when preventing that flooding door is pulled to certain altitude, it need be fixed on for a long time this highly.And existing hydraulic pressure or other draw high equipment when drawing high anti-flood, after will preventing that flooding door is fixed on a certain height, because the influence of equipment, anti-ly flood a door progressively landing downwards easily, in the course of time, and the generation that causes the accident easily.
Summary of the invention
The purpose of this utility model is to provide an a kind of anti-lifting locking device that floods.
For reaching above-mentioned purpose, the utility model provides a kind of to be prevented flooding a lifting locking device, is arranged at the described anti-both sides of flooding door, and described locking device comprises:
One pedestal is fixed on the capital construction concrete;
One locking piece, described locking piece comprises an articulated section, and diagonally extending goes out a lock arm and a counter-jib respectively in both sides, described articulated section, and described locking piece is articulated on the described pedestal by described articulated section;
And a support member, be fixedly arranged on and describedly anti-ly flood the reveal limit, and cooperate described lock arm to be provided with a locking mouthful on the described support member;
Further improvement of the utility model is: described pedestal is fixedly arranged on the capital construction concrete by pre-embedded steel slab;
Further improvement of the utility model is: described locking mouth is corresponding right-angle structure with the keyed end of described lock arm.
Cross above technical scheme, the anti-lifting locking device that floods that the utility model provides, it provides splendid operability, has higher safety simultaneously.Of the present utility model acting as can make the anti-stop of flooding door can be firm after raising, and makes it not be subjected to the influence of stay cord when stopping for a long time, thereby avoids problems of the prior art.

The specific embodiment
See also shown in Figure 1ly, be the anti-schematic diagram that floods a preferred embodiment of a lifting locking device of the utility model, as shown in the figure, be arranged at an anti-anti-lifting locking device that floods that floods a both sides and comprise:
One pedestal 10 is triangular shape, is fixed on the pre-embedded steel slab 92 that is embedded in 91 li of capital construction concrete, and its upper end offers a pivot hole 11;
One locking piece 20, described locking piece 20 comprises an articulated section 21, diagonally extending goes out a lock arm 22 and a counter-jib 23 respectively in 21 both sides, described articulated section, described locking piece 20 is articulated in by described articulated section 21 on the pivot hole 11 of described pedestal 10, and lock arm 22 and counter-jib 23 can 21 swings around the articulated section;
And a support member 30, be fixedly arranged on and describedly anti-ly flood door 40 sides, and cooperate described lock arm 22 to be provided with a locking mouthful on the described support member 30; This locking mouth is corresponding right-angle structure with the keyed end of described lock arm 22; Support member 30 supports by corresponding right-angle structure mutually with locking piece 20, fixes the anti-door 40 that floods;
When needs are closed anti-flood, as shown in Figure 2, need to promote earlier the anti-door 40 that floods, make the lock arm 22 of locking piece 20 and counter-jib 23 swings be in natural balanced state, will prevent flooding door 40 again and descend, up to assigned address as shown in Figure 3, anti-ly flood the student and fall to finishing; When needs are opened anti-flood, prevent flooding the position that door 40 rises to support member 30 approach locking parts 20, continue to rise, as shown in Figure 4, the anti-door 40 that floods promotes locking piece 20 two ends lock arms 22 and counter-jib 23 upset swings, continue to promote the anti-door 40 that floods, as shown in Figure 5, when locking piece 20 is lower than support member 30, the anti-door 40 that floods falls, support member 30 contacts with locking piece 20, prevents that flooding a unlatching finishes, and recovers state as shown in Figure 1.
