Second pulley, the 3rd pulley and steel wire rope, the hydraulic cylinder are arranged on the bottom plate of base of frame；Described first pulley is set
In hydraulic cylinder top, second pulley and the 3rd pulley are arranged on the top plate of framework upper end, and the 3rd described pulley is arranged at
Above fire door；Described steel wire rope one end is fixed on the top plate of framework upper end, the other end through first pulley, second pulley and
Fire door upper end is connected to after 3rd pulley；Relative slide construction is provided between framework in fire door, framework lower end is provided with fire door groove,
Shock-damping structure is provided with fire door groove, described shock-damping structure includes outer barrel interior bar and spring, and the interior bar is arranged in outer barrel, bullet
Spring is arranged between interior bar and outer barrel intracavity bottom, and intermeshing sawtooth knot is provided between described interior bar and outer tube side wall
Structure.
As a kind of preferred scheme, described framework both sides are equipped with hoisting structure；Both sides lifting is more stable.
As a kind of preferred scheme, two shock-damping structures are provided with described fire door groove.
As another preferred scheme, the relative slide construction between described fire door and framework is gear and rack；Phase
Position-limiting action is played to slide construction, avoids fire door track route from deviateing.
As another preferred scheme, the relative slide construction between described fire door and framework is roller and guide rail；Phase
Position-limiting action is played to slide construction, avoids fire door track route from deviateing.
The beneficial effects of the utility model are：The utility model pulls fire door by hydraulic cylinder, more stable, and fault rate
It is lower.When wire cable rupture, fire door is fallen, and pounds on shock-damping structure, and the interior bar of shock-damping structure pushes to be delayed by spring realization
Speed；In order to avoid fire door is upspring whereabouts repeatedly under the action of the spring, cause secondary injury, the utility model interior bar and outer barrel it
Between broached-tooth design is set so that interior bar pushes, by spring slow down once after achieve that protection door structure effect, then
Interior bar will be fixed on outer barrel bottom in the presence of broached-tooth design, avoid the secondary injury upspring, fallen repeatedly.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is shock-damping structure schematic diagram in Fig. 1.
1 hydraulic cylinder, 2 hoisting structures, 3 frameworks, 4 fire doors, 5 shock-damping structures, 6 outer barrels, 7 springs, 8 interior bars in figure.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
