Gap adjustment sheet 5, movable wedge guide plate 7, roller push rod component 8, electromagnet 10, electromagnet armature backhaul link stopper 11, electromagnet
Armature backhaul stop component 12 and electromagnet mounting plate 13 pass through the formation overall structure of support 9；Brake butterfly spring group 2 and gap adjustment
Piece 5 is inserted in brake adjustment spring force adjusting rod 3 and voussoir orientation lever 4 in movable wedge 6 respectively, and movable wedge 6 is inserted in machine
Seat 9, brake adjustment spring force adjusting rod 3 and movable wedge orientation lever 4 are through corresponding aperture on support 9 and are fastened by bolt A, the activity
Voussoir guide plate 7 is provided with inner side guide plate and outside guide plate, and the inner side guide plate is connected as a single entity with support 9, the outside
Guide plate is locked on support 9 by bolt, and electromagnet 10 is arranged on electromagnet mounting plate 13, and electromagnet mounting plate 13 passes through
Bolt is locked in support 9 as on overall inner side guide plate, roller 1 is arranged between inner side guide plate and outside guide plate in advance,
Electromagnet armature backhaul link stopper 11 is located at one end of electromagnet 10, and electromagnet armature backhaul stop component 12 is located at electromagnet armature
The bottom of backhaul link stopper 11, electromagnet armature backhaul stop component 12 is located on electromagnet mounting plate 13.
Described two groups symmetrical independent brake units are symmetrically mounted on the former car of elevator car top upper beam and lead boots position, adjustment two
Idler wheel surface leads the electricity that boots buffer gradable braking loaded on a kind of band with cage guide gap to uniform rear fastening, then by car
Above terraced accidental movement amount control device.
The movable wedge 6 can use multi-angle inclined-plane movable wedge, and the plane of symmetry of multi-angle inclined-plane movable wedge respectively has
One anti-" L " shape voussoir, the angle on wherein last inclined-plane is approximate 90 °, and there are two not contour vertical planes at the back side on inclined-plane, hangs down
Face directly equipped with a vertical round bar.
The action of electromagnet up or down by upper accidental movement relay KMS and lower accidental movement relay KMX upper contacts or
Lower contact is controlled, and the actuating signal of upper accidental movement relay KMS and lower accidental movement relay KMX up or down is by following controls
Signal concatenation processed is given：Elevator signal K1 out of service, maintenance cut-off signal KMJ, gate open signal KMM, upper car are unexpected
Movable signal KSK and lower car accidental movement signal KXK.When electromagnet (up or down) is acted, arrived by electromagnet action
Position signal K41 and K42, electromagnet armature reclaim disengaging roller axis hole backward.Under the roller freedom acted for upper accidental movement
Fall；And for the action of lower accidental movement by roller push rod component jack-up roller, now, roller 1 is held out against in car guide rail face 14
Between movable wedge 6, the tangential force produced between idler wheel surface tangent line and guide pass rotates roller, and the torque of generation is acted on first
Disc spring is oppressed on first inclined-plane of movable wedge makes movable wedge buffering receive place to the gap eliminated between gap adjustment piece.Work as rolling
When wheel turns to the second inclined-plane, rigidity extruding stop car is formed.When extruding force exceedes design load, roller will fall into the 3rd
Straight bevel facet, makes extruding force be limited to less than in the range of design load, thus avoids car by large impact.It is dynamic in electromagnet
After making in place, electromagnet action switch is driven on the driving lever top on its armature, and tripping magnet current supply circuit and elevator safety loop are (in detail
See Fig. 3 electric control theory figures).Meanwhile, the backhaul link stopper on its armature departs from the projection of electromagnet armature backhaul stop component,
The backhaul that cartridge stop is lived after armature movement on projection.
Reset after the utility model action, selects urgent electric operation operation or selection short circuit to return safely in elevator(lift) machine room
Inspection operation behind road, operation elevator along the reverse crawl of car accidental movement run to roller release (due to disc spring elastic force by
The clamping force for gradually discharging to maintain roller between movable wedge and car guide rail makes roller be moved with car, is displaced to roller and touches
Send out near position).The projection of electromagnet armature backhaul stop component is depressed into car top, makes the slow backhaul of armature until insertion is rolled
Axle hole and backhaul link stopper push down projection again, extract electromagnet action switch feeler lever, ON switch.
When elevator selection inspecting state operation, maintenance disconnects switch motion, cuts off control loop of the present utility model.
In figure 3, mark VCC is power supply, and YAS1 and YAS2 are upper anti-slip electromagnet, YAX1 and YAX2 be under anti-slip electromagnetism
Iron.
The upper and lower amount of movement control sensor that car accidental movement signal can be installed in hoistway by two gives, it is upper and
Lower two inductors are arranged on elevator car top, the flat bed of its installation site respectively when when Elevator landing and in the former hoistway of elevator
At tablet back gauge about 100~150mm, and its action is triggered using leveling inductor plate, make the control of elevator accidental movement amount 200
Between~450mm.
The utility model control car accidental movement amount signal can also be obtained by elevator encoder.It can be set by regulation
After car door opens certain gap, gate open signal is just provided；When elevator is in inspection travel state, this practicality is new
Type fails；Control electromagnet action can be realized by auxiliary reclay, can also be realized by way of microcomputer logic is programmed；Can be with
The up hypervelocity electric signal of a lift car is accessed, increases lift car up-running over-speed protection function.Go out for elevator brake
Existing brake force declines or failed, when causing accidental movement of elevator cage, can be right before elevator not yet enters high speed or overspeed condition
Lift car carries out the stop of controllable amount of movement；Decline for lift towing power or fail, cause accidental movement of elevator cage
When, it can not yet enter at a high speed or lift car is carried out before overspeed condition the stop of controllable amount of movement in elevator.
