Due to traction sheave make by frictional force drives hoist ropes movement, after elevator is used for a long time, hoist ropes with It easy tos produce slipping phenomenon or control system between traction sheave to fail to the control of traction machine, so as to cause the quick of car It rushes to summit or crouching bottom, less serious case leads to the impaired of passenger's body and elevator, serious to result even in passenger's death.For this purpose, people set The various device and method that car safety when elevator is run can be improved are counted, wherein most important mode is set on traction machine Set the arrestment mechanism of an Electromagnetic Control.When elevator power failure or because elevator failure control system cuts off the power supply of elevator When, electromagnet dead electricity in arrestment mechanism and lose electromagnetic attraction, arrestment mechanism is acted by the active force of tripping spring at this time, i.e., Locking braking can be realized to traction machine；And elevator is when having electricity, the electromagnet in arrestment mechanism obtain it is electric, to make arrestment mechanism release To the locking of traction machine, elevator can normal operation.
For example, disclosed one kind " elevator traction machine " in Chinese patent literature, notification number CN2401528Y, including One end of pedestal, motor, worm gear case, worm screw, worm gear shaft, hanging feet, worm gear, traction sheave, arrestment mechanism, the worm gear shaft is equipped with partially Heart set is equipped with tie-plate in the middle part of worm gear shaft, and tie-plate one end is mutually solid with worm gear, 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, adjustment is equipped 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 controlling switch, while motor passes through worm screw band Dynamic worm gear operating, and then drive traction sheave rotation, the rope of winding on the traction sheave that can drive lift car by tie-plate Lifting.When car runs to scheduled a certain destination, motor is set to stall by actuating control switch, while by brake Structure is dynamic.Braking principle is as follows：When motor power-off, the solenoid valve dead electricity of arrestment mechanism, the work that a pair of of band-type brake passes through spring force With locking braked wheel, motor shaft is set to stall rapidly by embracing the frictional force between the cap watt and braked wheel explained, to make elevator car Compartment is stabilized ground stop layers.
However existing elevator traction mechanism still has following defect in secure context：Due to existing arrestment mechanism Power comes from spring and electromagnet, and the frequency of use of arrestment mechanism is extremely low, that is to say, that arrestment mechanism is usually all in one Kind static standby mode when therefore, it is necessary to brake, is easy to lead to the failure of braking, Huo Zheyin because of the reasons such as stuck of spring The stuck of electromagnet causes arrestment mechanism to be difficult to reset unlock.In addition arrestment mechanism in locking traction machine or traction sheave still Make by frictional force realization, therefore the reliability of its locking is not high.
Utility model content
Purpose of the utility model is to solve be difficult to reliably braking, safety present in existing elevator traction mechanism Property not high problem, a kind of drag device with rescue door machine is provided, can be realized when elevator device has a power failure or breaks down The reliable braking of traction sheave is effectively prevented from car and rushes to summit or the safety accident at crouching bottom.
To achieve the goals above, the utility model uses following technical scheme：
A kind of drag device with rescue door machine, including：
Elevator control system is used to control the operation and fault detect of elevator；
Traction machine, the power source as driving car lifting；
The hoist ropes of the traction sheave being connected with traction machine and winding on the traction sheave constitutes the action of driving car lifting Executing agency；
Worm gear mechanism, worm gear therein is coaxially connected with traction sheave, and worm and wheel is meshed, to constitute traction The lockable mechanism of wheel；
Lazy-tongs include the protection motor connected with worm screw, controllable traction machine and the synchronous control for protecting motor speed Device processed, protection motor use servo motor, the isochronous controller to control traction machine respectively according to the transmission ratio of worm and wheel With the rotating speed of protection motor, keep worm screw synchronous with the holding of the transmission ratio of the rotating ratio of turbine and worm and wheel；
