Description
Technical field
The invention belongs to elevator safety component manufacturing technology fields, are related to a kind of safety catch, especially a kind of machine
The weightless safety tongs of tool formula Self-resetting.
Background technique
Elevator safety clamp device refers to, under the manipulation of elevator governor, when the speed of service of elevator is more than elevator speed limit
When the limitation speed of device setting, or in the case where fracture and relaxation occur for suspension strop, the urgent stop of carriage and being clamped in is led
A kind of safety device of state is remain stationary on rail.Safety tongs is important to the safe operation offer of elevator, effect is effectively protected,
The working principle of safety tongs is：Speed limiter wire rope is driven by safety tongs lever, speed limiter wire rope and limit are kept by tensioning wheel
The frictional force of fast device wheel, so that limiter of speed wheel speed is consistent with the carriage speed of service, when the carriage speed of service is more than 1.15
Times normal speed when, limiter of speed movement, by stop rope block oppress speed limiter wire rope, stop it, and drive safety tongs
Lever acts safety tongs.
According to GB7588-2003《Elevator manufacture and installation safety standard》9.8.3.2 regulation：It must not electricity consumption air-liquid pressure
Or the device of air-operated control carrys out safe operation pincers, therefore, existing safety tongs is all using mechanical limiter of speed as measuring mechanism, only
When elevator speed meets or exceeds defined mechanical governor tripping speed, it is dynamic that shift mechanism control safety tongs could be triggered
To make, mechanical limiter of speed and the intrinsic hysteresis quality of safety tongs idle running response time cannot be solved fundamentally, braking process is affected,
System safely controllable property is poor, there is safety risk out of control, to overcome this disadvantage, Authorization Notice No. CN104326322B（Specially
Benefit number 201410548328.7）A kind of weightless safety tongs of patent disclosure, eliminate the speed limit measuring mechanism of conventional security pincers
And lifting control mechanism still need to increase remote reset system or automatic reset system, if using motor lead screw remote reset
Mode is unable to complete reset when no external energy drives, and will affect the rescue under emergency braking, to solve this problem, needs to increase
Add control system and external energy and substantially increases product cost；If working as external energy using electromagnet remote reset mode
When amount missing or deficiency, electromagnet is also to be unable to complete reset.
Summary of the invention
To overcome existing weightless safety tongs system reset function to rely on external energy driving, length of run reset and emergency relief
Bring control is complicated, manufacturing cost is high, resets insecure realistic problem, and the present invention provides a kind of mechanical resettings
Weightless safety tongs.
The technical solution adopted by the present invention is that：
A kind of weightless safety tongs of mechanical resetting, including mounting base arrestment mechanism, resetting-mechanism, the arrestment mechanism are answered

The arrestment mechanism connection makes the elastic component accumulation of energy when the arrestment mechanism generates braking maneuver；When the arrestment mechanism
When release, the elastic component resets the arrestment mechanism.
Preferably, the resetting-mechanism further includes reset assembly, when arrestment mechanism generation movement, the brake
Structure triggers the reset assembly movement；When arrestment mechanism release, the reset assembly resets the resetting-mechanism.
Preferably, the reset assembly includes restoring board, elastomer, and the elastomer is installed on the restoring board, works as institute
When stating arrestment mechanism generation movement, the arrestment mechanism makes the elastomer accumulation of energy by the restoring board；When the brake
When structure discharges, the elastomer resets the resetting-mechanism by the restoring board.
Preferably, the arrestment mechanism includes wedge assemblies, and the wedge assemblies include voussoir, the voussoir and the bullet
Property part connection.
Preferably, the safety tongs is equipped with weightless trigger mechanism, and under normality, the weightlessness trigger mechanism is in equilibrium-like
State；When abnormal, the weightlessness trigger mechanism triggers the arrestment mechanism movement.
Preferably, the weightless trigger mechanism includes pouring weight, pouring weight connector, and the pouring weight passes through the pouring weight connector
It is connected in the mounting base, is rotatably mounted to the resetting-mechanism.
Preferably, the pouring weight includes left counterweight, right counterweight, counterweight connector, and fold symmetry is matched on the left counterweight, the right side
Setting is connected by the counterweight connector.
Preferably, the weightless trigger mechanism includes latch hook, and the latch hook is rotatably mounted to the resetting-mechanism, normality
Under, the latch hook blocks the arrestment mechanism；When abnormal, the latch hook discharges the arrestment mechanism, and the arrestment mechanism generates
Braking maneuver.
Preferably, the safety tongs is equipped with Electromagnetic Control mechanism, and under normality, the Electromagnetic Control mechanism is in static shape
State；When abnormal, the Electromagnetic Control mechanism triggers the arrestment mechanism movement by the weightless trigger mechanism.
Preferably, the Electromagnetic Control mechanism includes electromagnet, electromagnet fixing seat, electromagnet push plate, the electromagnet

Contracting is forced, pull rod 5-1-2 drives left feedback pressing plate 5-5, right feedback pressing plate 5-6 respectively with left feedback shaft 5-3, right feedback shaft
5-4 is fulcrum rotation, the side flange 5-5-2,5-6-2 pushing wobble plate 2-5 of left feedback pressing plate 5-5, right feedback pressing plate 5-6, then,
It connects wobble plate 2-5 and left wedge assemblies 2-1, the left energy-storaging spring 5-7 of right wedge assemblies 2-2, right energy-storaging spring 5-8 to stretch, pendulum
The wobble plate slot 5-2-4 of plate 2-5 blocks back again in latch hook 3-8, completes entire reset accumulation of energy movement.When carriage or counterweight（Or balance
Weight）Lift, wedge assemblies 2-1,2-2 release, at this point, wedge assemblies 2-1,2-2 are withdrawn into initial bit by energy-storaging spring 5-7,5-8
It sets realization to reset, reset assembly 5-1 loses the constraint of wedge assemblies 2-1,2-2, and pressure spring 5-1-5 springs back to reset assembly 5-1
Initial position completes the reset of safety tongs.
All frictional force by between voussoir and guide rail carry out accumulation of energy, discharge the mechanism for resetting wedge assemblies after accumulation of energy
In the scope of this patent.
The preferred embodiment of the present invention is described in detail above, for those of ordinary skill in the art, according to
According to thought provided by the invention, will change in specific embodiment, and these changes also should be regarded as guarantor of the invention
Protect range.
