Abstract
The utility model discloses a kind of car resistance to movement device, this device comprises electric detecting unit, drag unit, control unit, start unit, reset unit, power module.This device is with sensor detecting and magnet switching mode; make installation device action on the elevator car; lift car can be locked on guide rail when the improper mobile car in door-opened elevator region; prevent car abnormal mobile, guarantee that special device that passenger passes in and out elevator safety reaches the object of protection passenger.This device, with electromechanical integration patten's design, has automatic detection, automatically identifies, fast, the advantage that stopping distance is short, is preventing from the potential safety hazards such as elevator shearing, extruding play great effect in response.
Description
Technical field
The utility model relates to a kind of car resistance to movement device.
Background technology
At present, along with the progress of society, people's living standard constantly improves, and the use of elevator is more and more general, and most of lift car usually occurs abnormal mobile, there is the potential safety hazards such as elevator shearing, extruding.
Elevator operative installations, being all the movement device for detecting during lift car hypervelocity, being precarious position and driving brake device for elevator action to make deceleration of elevator stop when it can only detect elevator overspeed; But for the elevator low speed slowly movement when dangerous generation, the elevator governor of prior art cannot detect, therefore also would not produce corresponding action and make deceleration of elevator stop, thus initiation potential.
Such as when Elevator landing and elevator cab door is opened, now lift car is done operation out of control because of certain electric elements fault or is not enough to maintain the slow movement up or down of lift car caused by some other X factors such as the flat bed quiescence of car because of elevator main traction, in such cases, the speed of lift car movement is very low, not yet reach hypervelocity responsiveness, therefore elevator governor in the past cannot detect that the speed of now elevator is dangerous speed, on velocity limiter, corresponding actions mechanism therefore also can not action, therefore also action cannot be provided to indicate to braking element, braking element also would not go to allow the car stop of slowly movement, if now just there is passenger to be fixedly between elevator cab door and elevator door, lift car movement up or down likely will cause the injury of shearing to passenger, the death of passenger can be caused time serious.
Summary of the invention
Technical problem to be solved in the utility model is for the defect in above-mentioned background technology
,provide a kind of structure simple and car can be detected move, thus ensure the car resistance to movement device of elevator safety for row.
The utility model is for solving the problems of the technologies described above by the following technical solutions:
A kind of car resistance to movement device, comprise start unit, reset unit, control unit, power module, this device also comprises the electric detecting unit for detecting car amount of movement and the drag unit for stop car; The corresponding port of described start unit, reset unit, drag unit and electric detecting unit link control module, described power module provides required electric energy for this device.
Preferably, described control module is micro controller system.
Preferably, described electric detecting unit is arranged on guide rail.
Preferably, described electric detecting unit comprises the sensor of closedown situation for detecting car position and the Room, gate, runs contactless switch and braking contactor for the operation conditions detecting elevator.
Preferably, described power module is for being arranged on the crossbeam of car.
Preferably, described power module is UPS.
After adopting such scheme, the beneficial effects of the utility model are:
It take guide rail as all kinds of vertical lifts of sense of motion that this device can be used for all kinds of, with sensor detecting and magnet switching mode, make installation device action on the elevator car, lift car can be locked on guide rail, with electromechanical integration patten's design when the improper mobile car in door-opened elevator region, there is automatic detection, automatic identification, response is quick, the advantage that braking distance is short, effectively prevent the potential safety hazards such as elevator shearing, extruding, bring guarantee to the safety of passenger.
Accompanying drawing explanation
Fig. 1 is system architecture schematic diagram of the present utility model.
Detailed description of the invention
Below with reference to accompanying drawing, the technical solution of the utility model is described in detail.
It take guide rail as all kinds of vertical lifts of sense of motion that this device can be used for all kinds of, with sensor detecting and magnet switching mode, make installation device action on the elevator car, lift car can be locked on guide rail, with electromechanical integration patten's design when the improper mobile car in door-opened elevator region, there is automatic detection, automatic identification, response is quick, the advantage that braking distance is short, effectively prevent the potential safety hazards such as elevator shearing, extruding, bring guarantee to the safety of passenger.
Specific embodiment is as follows: as shown in Figure 1: a kind of car resistance to movement device, comprise start unit, reset unit, control unit, power module, this device also comprises the electric detecting unit for detecting car amount of movement and the drag unit for stop car; The corresponding port of described start unit, reset unit, drag unit and electric detecting unit link control module, described power module provides required electric energy for this device.Described control module is micro controller system, described electric detecting unit is arranged on guide rail, described electric detecting unit comprises the sensor of closedown situation for detecting car position and the Room, gate, operation conditions for detecting elevator runs contactless switch and braking contactor, described power module is for being arranged on the crossbeam of car, and described power module is UPS.
During work, elevator door may be in power failure state when opening, therefore device is powered by UPS, device is arranged on car, reliably be fixed on the crossbeam of car, readiness for operation is entered after elevator stops or door is opened, car position and the Room is detected by sensor, the closedown situation of gate, by running the operation conditions of contactless switch and braking contactor supplementary contact detection elevator, work as the Room, gate is opened, under the state that system does not send operating instruction, when car has mobile, device detects that car position amount of movement exceedes specialized range, then send shutoff instruction immediately, electromagnetic start unit action on lift car resistance to movement device, the brake facing locking guide rail of release brake stop unit, car cannot be moved, electric safety switch cuts off the safety return circuit power supply of elevator simultaneously, make elevator device dead electricity.After risk is got rid of, carry out hand reset by professional repair and maintenance personnel to device, elevator recovers normal.
