As Figure 1-3, a kind of anti-slip terraced safety guard of new towed elevator, the device include：With engaging groove 2
Traction sheave of tractor 1, two stop devices 7, the electromagnetism actuating mechanism 3 of Electromagnetic Control, two pairs of permanent magnet magnetic steel discs 4 and Hall
Detection means 8, monitor logic controller.
The present embodiment original traction sheave 1 outside process two semi-circular shape engaging grooves 2 concentric with traction sheave 1, two
Separated part is stop device 7 described in the present embodiment in individual concentric semi-circular shape engaging groove 2, two phases of stop device 7
For the center of circle symmetric design of traction sheave 1, coordinate the motion for preventing traction sheave with electromagnetism actuating mechanism；In two stop devices
7 outsides are respectively equipped with a permanent magnet magnetic steel disc 4, for marking each stop dog position.
The electromagnetism actuating mechanism 3 is the movement device that two sides are L-type, and the movement device can be relative to traction sheave
1 moves vertically, and can not be moved horizontally relative to traction sheave 1；Each its longer one end of L-type movement device is parallel to traction sheave
1 is set, and space angle is 90 °, and its inner side is provided with the electromagnet alignment pin 31 and Hall detection apparatus 8 of Electromagnetic Control, electricity
Magnet alignment pin 31 can be plugged together in traction sheave engaging groove completely, and Hall detection apparatus 8 is arranged under electromagnet alignment pin 31
Side, for detecting the position of permanent magnet magnetic steel disc 4；Hall detection apparatus 8 and permanent magnet magnetic steel disc 4 are arranged in parallel.
The monitoring logic controller is to detect Elevator landing signal, layer gate signal, car gate signal, the state of brake 5
The monitoring device of signal and rotary encoder through signals, and confirm whether elevator is failure shape by monitoring and analyzing above signal
State, judges whether electromagnetism actuating mechanism 3 needs to act.
Wherein, the center arc length of permanent magnet magnetic steel disc 4 is greater than the center radian circumference of stop device 7 and positioned with electromagnet
The diameter sum of pin 31, to facilitate Hall detection apparatus 8 to detect the position of permanent magnet magnetic steel disc 4.
Its method of work is：After elevator obtains reaching the call instruction of certain stop, elevator normal operation to specified stop
That is target stop onlocking zone, elevator carries out throw-over, deceleration, parking, band-type brake, door opening action when arriving at, and in the process, owns
Step switch signal all enters in the monitoring logic controller in the lump, carries out state of elevator monitoring.After Elevator landing, in real time
Monitor brake action signal, layer gate switch closure signal and rotary encoder through signals.When elevator normal operation, monitoring is patrolled
Collect controller and be judged as normal condition, do not export any control signal, protection device is failure to actuate；When elevator is in enabling region,
Monitoring logic controller detects that if any layer, gate state be door opening state, and rotary encoder has rotational pulse signal output
(during do not judge direction), that is, judge that current state is malfunction, slip the abnormal situation of movement such as ladder, monitoring logic control
Device output control signal processed, electromagnetism actuating mechanism 3 are acted according to the state of position detecting element, make electromagnetism actuating mechanism 3
Electromagnet alignment pin 31 insert traction sheave 1 engaging groove 2 in, when the stop device 7 on traction sheave 1 moves to some electromagnet
During 31 position of alignment pin, electromagnet alignment pin 31 can stop that electromagnet alignment pin 31 continues to move, so as to stop locking failure
Elevator.Because two space angles of electromagnet alignment pin 31 are 90 °, and two stop devices 7 are symmetrical arranged into 180 °, so
After electromagnetism actuating mechanism 3 acts, when traction sheave 1 rotates to any opening position, it can at least ensure an electromagnet alignment pin 31
Action, main frame traction sheave is subjected to locking.Elevator slips the arc length that terraced displacement maximum is only an engaging groove 2 during this,
Car slips terraced stroke and is up to the circumference of traction sheave 1 less than 1/2, and slipping terraced displacement so as to ensureing lift car under door opening state exists
In safety zone.
The stall protection (such as up hypervelocity or overspeed descending state) that the system is bel not applied under dynamic；The present apparatus is implemented to protect
After shield, range is in the distance of traction sheave half revolution to car up and down, facilitates personnel to come in and go out；When detecting malfunction,
And after protection device action, faulty lock function, i.e., the state locking in enabling region, it is necessary to which hand is carried out by professional
Elevator could use after dynamic removing fault recovery, avoid the occurrence of time hair injury accident.
The present invention uses above structure type, can effectively prevent elevator car of the car under the door opening state of flat bed region
Railway carriage or compartment because of traction machine brake system non-functional or traction foot wheel abrasion, caused by steel wire iope slippage or brake cause when can not brake
Lift car slip the generation of the accidental movements such as ladder or out-of-control condition, so as to effectively prevent thus to bring personnel's injury,
Accident etc..It is non-that requirement is made to elevator global design in hardware realization, original traction sheave is simply made into satisfactory change
