Technical field:
The utility model relates to a kind of velocity limiter of building hoist, particularly relates to the anti-falling safety device that a kind of large-tonnage building hoist is used.
Technical background:
Along with high speed development of national economy, building hoist begins bringing into play enormous function in growing field, construction site such as large-engineering, high-rise particularly, and building hoist becomes a kind of requisite transportation device.Yet, in order further to accelerate job schedule, enhancing productivity, people wish to have a kind ofly can carry more that the elevator of heavy amount occurs.The anti-falling safety device of existing building hoist comprises and the drag cone drum of the shell of guide rail bracket ingear drive gear mechanism, revolution, revolution, centrifugal, spring, screw rod; Drive gear mechanism comprises sun gear, drag cone drum and the same axle mounting of sun gear; The drag cone drum is installed in the enclosure, shell comprises inner conical surface, on the drag cone drum, be provided with the male cone (strobilus masculinus) similar to the inner conical surface shape of shell, a centrifugal end that is installed in the drag cone drum near drive gear mechanism, spring is installed between centrifugal and drag cone drum, is provided with screw rod at the drag cone drum away from an end of drive gear mechanism.Existing this anti-falling safety device, building hoist is when overspeed, drive centrifugal rotation of anti-falling safety device by sun gear, centrifugal overcomes spring tension and drives the rotation of drag cone drum, make the precession simultaneously of coupled screw rod, make drag cone drum and housing contacts increase friction force gradually, realize that cage brakes gently.Existing this anti-falling safety device, in operational process, centrifugal running velocity of its centrifugal operating speed and anti-falling safety device is consistent, so the output of the kinetic moment of this kind anti-falling safety device is restricted, is difficult to satisfy the elevator of carrying large-tonnage load carrying ability.
Summary of the invention:
The purpose of this utility model provides a kind of anti-falling safety device of safe, reliable, simple in structure, building hoist that lock torque is big.
A kind of anti-falling safety device of building hoist comprises and the drag cone drum of the shell of guide rail bracket ingear drive gear mechanism, revolution, revolution, centrifugal, first elasticity reset device, screw rod; Drive gear mechanism comprises sun gear; The coaxial installation of drag cone drum in the enclosure, shell comprises inner conical surface, on the drag cone drum, be provided with the male cone (strobilus masculinus) similar to the inner conical surface shape of shell, a centrifugal end that is installed in the drag cone drum near drive gear mechanism, first elasticity reset device is installed between centrifugal and drag cone drum, be provided with screw rod at the drag cone drum away from an end of drive gear mechanism, screw rod is coaxial with the drag cone drum, also comprise speed reduction gearing, speed reduction gearing comprise with the co-axially fixed big gear wheel of sun gear and with the coaxial mounted miniature gears of drag cone drum.The anti-falling safety device of large-tonnage building hoist of the present utility model, on existing anti-falling safety device basis, done corresponding improvement, increased speed reduction gearing, made under the immovable situation of friction force of drag cone drum and shell, anti-falling safety device can have bigger lock torque output.Its mode of operation is: when the elevator craning cage overspeed, with tooth bar ingear miniature gears overspeed operation, reductor transmission by anti-falling safety device drives centrifugal running, centrifugal overcomes spring tension and drives the rotation of drag cone drum, the screw rod precession, the drag cone drum and the friction force of shell are increased, the braking cage, because driving device has increased the one-level speed reduction gearing in operational process, so its operating speed of centrifugal will be faster than centrifugal running velocity of traditional anti-falling safety device in operational process, and when the bulging friction force with shell of drag cone is constant, this novel anti-falling safety device has bigger lock torque output, more can satisfy the requirement of large-tonnage building hoist, and use safer, reliably.
As improvement, the big gear wheel of speed reduction gearing and pinion.
As further improvement, drive gear mechanism also comprises and sun gear ingear phantom gear, phantom gear and guide rail bracket engagement.
As another improvement, be provided with second elasticity reset device near screw rod one end at the drag cone drum.
As improvement, second elasticity reset device comprises disk spring that is enclosed within on the drag cone drum and the pressure nut that is fixed on the drag cone drum.
The beneficial effect of the new anti-falling safety device type of this practicality be simple in structure, lock torque big, it is safer to use, reliably, more can satisfy the requirement of large-tonnage building hoist.
