Description

A kind of fire door hoisting device
Technical field
The utility model is to be related to a kind of improvement of fire door hoisting device.
Background technology
Traditional heating furnace or large-scale smelting furnace it is door opened general all by the way of electric hoist is lifted, it is this It is fine that mode lifts very convenient and effect to the fire door of small tonnage.But its fault rate is high, the steel wire rope of lifting is also frequent The problem of being broken, when steel wire rope is broken, fire door will hurtle down, it is easy to the damage of fire door and body of heater is caused, Therefore it is badly in need of fire door and body of heater flimsy problem during a kind of solution wire cable rupture.
Utility model content
Operated steadily in view of the deficienciess of the prior art, technical problem to be solved in the utility model is to provide one kind And the fire door hoisting device with fire door protection structure.
The utility model is adopted the following technical scheme that to complete:A kind of fire door hoisting device:Including being arranged at fire door The framework of periphery, it is characterised in that:Framework side is provided with hoisting structure, described hoisting structure include hydraulic cylinder, first pulley, 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.
With reference to the accompanying drawings shown in 1-2, a kind of fire door hoisting device:Framework 3 including being arranged at fire door periphery, its feature exist In:The side of framework 3 is provided with hoisting structure 2, and described hoisting structure 2 includes hydraulic cylinder 1, first pulley, second pulley, the 3rd cunning Wheel and steel wire rope, the hydraulic cylinder 1 are arranged on the bottom plate of the bottom of framework 3;Described first pulley is arranged at hydraulic cylinder 1 and pushed up End, second pulley and the 3rd pulley are arranged on the top plate of the upper end of framework 3, and the 3rd described pulley is arranged at the top of fire door 4; Described steel wire rope one end is fixed on the top plate of framework upper end, and the other end passes through first pulley, second pulley and the 3rd pulley After be connected to fire door upper end;Relative slide construction is provided between framework 3 in fire door, the lower end of framework 3 is provided with fire door groove, fire door groove Interior to be provided with shock-damping structure 5, described shock-damping structure includes outer barrel 6, interior bar 8 and spring 7, and the interior bar 8 is arranged in outer barrel 6, Spring 7 is arranged between interior bar 8 and outer barrel intracavity bottom, and intermeshing saw is provided between described interior bar 8 and the side wall of outer barrel 6 Toothing.
The described both sides of framework 3 are equipped with hoisting structure 2;Both sides lifting is more stable.
Two shock-damping structures 5 are provided with described fire door groove.
Relative slide construction between described fire door 4 and framework 3 is gear and rack;Played with respect to slide construction spacing Effect, fire door track route is avoided to deviate.
