For example, disclosed one kind " elevator traction machine " in Chinese patent literature, notification number CN2401528Y, including Pedestal, motor, worm gear case, worm screw, worm gear shaft, hanging feet, worm gear, traction sheave, arrestment mechanism, one end of the worm gear shaft are equipped with inclined Heart set is equipped with tie-plate in the middle part of worm gear shaft, and tie-plate one end and worm gear are mutually solid, the other end and traction sheave mutually admittedly, in tie-plate and Bearing is respectively set between worm gear and between tie-plate and traction sheave, is equipped with adjustment in a pair of of hanging feet bottom of setting worm gear shaft Gasket.When work, first power on, so that arrestment mechanism is in energized state by control switch, while motor passes through worm screw band Dynamic worm gear operating, and then traction sheave rotation is driven by tie-plate, the rope of winding on the traction sheave can drive lift car Lifting.When carriage runs to scheduled a certain destination, stall motor by actuating control switch, while by brake Structure is dynamic.Braking principle is as follows：When motor power-off, the solenoid valve power loss of arrestment mechanism, the work that a pair of of band-type brake passes through spring force With locking braked wheel, stall motor shaft rapidly by embracing the frictional force between the cap watt and braked wheel explained, to make elevator car Compartment is stabilized ground stop layers.
But the arrestment mechanism of this structure, band-type brake is needed to apply enclasping force, if the enclasping force of band-type brake is insufficient, sedan-chair Compartment can not fast braking be easy to cause in carriage passenger panic there is also lifting moving.And after band-type brake holds braking tightly, scene It cannot achieve and save oneself, need to be carried out external rescue by special rescue personnel by the mechanism of a series of complex, rescue waits Time it is long, than relatively hazardous, the passenger in carriage cannot be rescued the process of rescue at the first time, may be delayed and be rescued The opportunity helped.
Summary of the invention
The utility model solve existing elevator by band-type brake carry out emergency braking, be easy because band-type brake enclasping force not Foot, cause carriage can not fast braking, it is concealed to provide a kind of counterweight the defect that braking reliability is low, elevator safety is not high Two-shipper drag device, elevator device break down when can fast braking, and directly by way of a kind of traction sheave locking into The braking of row locking, braking reliability is high, and carriage can effectively be avoided to rush to summit or the safety accident at crouching bottom.
The utility model also solves existing elevator and can not save oneself, and external professional rescue team is needed to be rescued, It is waiting for a long time in carriage, it is also easy to lose the defect of the first rescue time, a kind of concealed two-shipper drag device of counterweight is provided, It with rescue motor, can be saved oneself in carriage by passenger, win for the first rescue time, improve elevator safety.
The utility model provides a kind of concealed two-shipper drag device of counterweight, and counterweight is arranged by the way of diagonal, is avoided The side wall of carriage realizes the multidirectional enabling of carriage.
The utility model provides a kind of concealed two-shipper drag device of counterweight, using cavity type hoistway column, and by counterweight It is set in the cavity of hoistway column, realizes fully transparent hoistway and carriage.
The specific technical solution of the utility model is：A kind of concealed two-shipper drag device of counterweight, including：
Traction machine, the power source as carriage lifting；
Traction sheave connect with traction machine and is driven by traction machine, and hoist ropes is arranged on traction sheave, and hoist ropes connects carriage And draw carriage lifting；
Counterweight is arranged symmetrically and is hidden in the hoistway with interior liftway, and one end of counterweight and hoist ropes, which connects, to be used In balance carriage；
Worm gear mechanism, worm gear is coaxially connected with traction sheave and rotates synchronously in company with traction sheave, worm and wheel engagement Constitute the lockable mechanism of traction sheave；
Synchronization mechanism connect with worm screw and worm screw is driven to keep rotating synchronously with worm gear, when elevator runs well, worm screw It is mutually separated always with worm gear.
A worm gear mechanism is arranged in the utility model, and worm gear and traction sheave are coaxially connected.It is known that worm gear Worm screw has self-locking, that is to say, that worm gear is unable to drive worm screw rotation, and worm gear rotation can only be driven by worm screw.For this purpose, this A synchronization mechanism is arranged to realize that worm and wheel is synchronous in utility model, and worm and wheel keeps synchronizing, and worm screw would not be right Worm gear causes self-locking, and when system blackout, worm screw stops operating, and reliable mechanical self-latching can be formed to worm gear, thus to draging Running wheel forms reliable braking；When traction machine is out of control leads to velocity anomaly, worm gear can not form synchronous, worm screw at this time with worm screw The rotation of worm gear can be hindered automatically, to can avoid carriage rapid aerating-holding or crouching bottom.It is known that in the prior art, worm gear Worm screw is a kind of transmission mechanism with self-locking effect, and in order to improve safety, people can be arranged some detectable on elevator The sensor of carriage lifting speed, to cut off the power when fast lifting occurs in carriage and to brake traction machine.And this is practical new On the one hand the worm and gear of type has self-locking, while may make up a reliable mechanical sensing device, on the one hand ensures Traction sheave is reliably braked when abnormal conditions occur in power failure or traction machine, on the other hand can timely perceive the non-of traction machine Run well, so can significantly hoisting elevator run when safety.The worm gear of the utility model turns in company with traction sheave is synchronous Dynamic, the load of worm screw is far smaller than the load of traction sheave, it may be said that worm screw is equivalent to non-loaded, therefore the safety of synchronization mechanism Can be reliable, it is higher compared to the carrying means safety coefficient that traction machine and traction sheave form, therefore synchronization mechanism substantially will not Reaction is caused to carrying means.The worm and gear of the utility model is not a transmission power when elevator operates normally Mechanism, and the facewidth of worm screw can be smaller than the space width of worm gear, therefore can have between one between worm tooth and the tooth socket of worm gear Gap can avoid generating contact friction between worm and wheel, simultaneously to make to keep discrete state between worm tooth and worm-gear toothing Isochronous controller is reduced to the control accuracy requirement of traction machine, synchronous motor revolving speed, is avoided because turning between traction machine, synchronous motor The slight deviations of speed cause the frequent shutdown of elevator.Certainly this is a kind of optimal working condition, and worm and wheel is not in contact, Also abrasion and noise etc. would not be generated, and this gap is also beneficial to improve the fault-tolerant ability of elevator, as long as keeping in fact Worm and wheel is synchronous.
Preferably, synchronization mechanism uses servo motor, or using the purely mechanic kind of drive by worm screw and traction machine or Person's traction sheave is connected.Synchronization mechanism uses servo motor, and connection is more convenient, there is a speed between servo electrode and traction machine Match；Synchronization mechanism can also use pure mechanic structure, and synchronization mechanism uses mechanically operated mode, high reliablity, failure Rate is lower, eliminates automatically controlled, reduces costs, also avoids automatically controlled bring unstable factor, that is to say, that worm gear at this time It is to be driven by traction machine, and worm screw is then by synchronous machine drives as traction sheave, worm gear and worm screw are in phase Mutual independent state hinders so that worm screw be made not formed to the rotation of worm gear.The power source of synchronization mechanism can come from traction Machine is also possible to come from traction sheave, can also be from worm gear, and certainly, the power source from worm gear is transferred to worm screw and needs to set A clutch is set, which can disconnect transmission when needing worm screw self-locking, and the difference of power source just needs to design The appropriate transmission ratio of synchronization mechanism, thus to guarantee that worm and gear is synchronous.
