Embodiment, the utility model are not limited to following embodiment.
Shown in the figure, multi-functional gauntry crane, elevator safety device comprise lifting mechanism, safety device mechanism, and the pulley hinge mount 1.1 of lifting mechanism is connected with the central pulley 1 of hanging basket beam, lifting drawspring 10, adapter plate respectively, its adapter plate is connected with chain 2 respectively, combines with hanging basket beam 18; Safety device mechanism stops mechanism by braking mechanism, double team mechanism, watt plug 22 and off-axis mechanism and forms, its fixed vertical tooth 7 is stopped the bearing point, fixedly tubing string 6 is installed in respectively on the fixed bearing wall, off-axis double team 25, operation locating wheel 26, watt plug pulley yoke 23, hook are located at respectively on the connecting panel 20, pulling frame 24 is connected on the off-axis double team 25, and thick stick pull bar 21 is fixed on the double team 8; The stressed tooth 5 of braking mechanism is meshed with fixed vertical tooth 7, driving cog 13 respectively, driving cog 13 is coaxial with brake drum 4 or brake disc 4, its by bearing fixing on hanging basket beam 18, the double team 8 of double team mechanism is connected on the connecting panel 20, and wrap mutually with fixing tubing string 6, connecting panel 20 is fixed on the hanging basket beam 18, and double team extension spring 9 is arranged above the double team axillare, chain 2 is arranged below it; Stop mechanism and be made up of range regulator 31, hook 32, cross bar 33, double team 8, be installed in respectively on hanging basket beam 18 and the connecting panel 20, leading respectively by range regulator 31 acts on hook 32, cross bar 33, double team mechanism respectively, and its hanging basket is stopped.
Shown in the figure, when the utility model is under normal circumstances constructed operation, pulley 1 starting of hanging basket beam central authorities produces pulling force, pulling chain 2 and lever 3, lever 3 pulling brake drum 4 or brake discs 4, chain 2 pulling double teams 8, double team 8 separates with fixing tubing string 6, thick stick pull bar 21 thick sticks pullings watt plug 22, pulling frame 24, pulling frame 24 drive off-axis double teams 25, and insurance locating wheel 15 separates with fixing tubing string 6.The normal running job up and down of hanging basket.The safety device mechanism of this moment is in the pressure off working state.Brake drum 4 or brake disc 4 keep running and are idle running with stressed tooth 5 and driving cog 13.
As can be seen from the figure, when the lift heavy main rope because serious wear fracture suddenly or steel rope squeezes off because of job-hopping or hanging basket roof fall when severing the lift heavy main rope, hanging basket beam central authorities' pulley 1 and sheave shaft break away from the constraint of winch tractive force, hanging basket beam central authorities pulley 1 descends, and loosens lever 3, range regulator 31, hook 32, cross bar 33, double team mechanism and the chain 2 that is connected with double team 8 simultaneously.Brake drum 4 or brake disc 4 in hook 32, cross bar 33, the lever 3 pulling brakes are stopped tightly, and at this moment, the driving cog 13 on brake drum 4 or the brake disc 4 same axles is shifted to stressed tooth 5, and stressed tooth 5 is shifted to fixed vertical tooth 7, makes the hanging basket stop motion, produces insurance.Chain 2 is stopped as selecting double team mechanism by guiding double team mechanism, and through the range regulator roll adjustment, double team mechanism is up drawn by double team extension spring 9, under the effect of the afterburning spring 12 of double team, makes double team 8 encase fixedly tubing string 6.Thick stick pull bar 21 pulling pulling framves 24 are upwards drawn by extension spring 27, a watt plug spring 29, watt plug 22, are close to insurance locating wheel 15.Off-axis double team 25 makes a watt plug 22 under a watt plug spring 29, extension spring 27 effects, off-axis double team 25 encases fixedly tubing string 6, hanging basket stop motion.Reached insurance brake drum 4 or brake disc 4 and double team 8 and worked simultaneously, promptly reached multi-functional insurance simultaneously, breaking-up and personnel casualty accidents that actv. avoids the gantry hoist hanging basket to cause equipment because of disconnected rope falls take place.
Give hanging basket frame 19 by the double team hinge with the pulling force transmission, operation locating wheel 26 firm hanging basket framves 19.14 guiding of track adjusting wheel tension.
Off-axis double team 25, operation locating wheel 26 installation sites can be changed.Insurance locating wheel 15 can suitably increase with the gap of tubing string 6, makes watt plug 22 a wall thickness thickening, so that increase watt plug 22 intensity.Safety mechanism and stop mechanism select to use according to user's request.
Stop mechanism: increase roll adjustment by range regulator 31, abdicate stop position, its hook 32, cross bar 33 double team mechanisms are stopped.Range regulator 31 functions mainly by the effect of thick stick pull bar guiding, decontrol by thick stick pulling range regulator 31, and after the relieving, hook 32 or cross bar 33 or double team mechanism reach stop position under action of the spring.Buffer spring is positioned on the sleeve pipe outer arm, reduces impulsive force.
List rests on the bearing point with hook 32, cross bar 33, under the situation of coincidence, can play disconnected rope safety effect.Not under the coincidence situation, single with hook 32 and cross bar 33 conduct insurances, generally say to have begun safety effect.Stop bearing point is stop position setting (derrick is generally established bearing point in 1.5M) as required, when restricting below bearing point 35 as breaking, the impact strength that directly drops when hanging basket is very big, be easy to cause cross bar 33 or link up with 32 and bearing on anchor point damage.Hook cover rod-type slide construction is made up of sleeve pipe 32.1, axle 32.2, hook bar 32.3.When hanging basket was stopped back decline, range regulator pinned, and descended after its hanging basket rising is moving again.As select independent Removable hook 32 to stop, and hanging basket does not rise, and thick stick pulling guide rope drives Removable hook pins range regulator by return spring, can directly descend.
