Abstract
The invention discloses a lift car movement-preventing device comprising an electrical testing unit, a brake unit, a control unit, a starting unit, a reset unit and a power source module. Devices installed on an elevator lift car act through a sensor testing technology and an electromagnet on and off mode, the elevator lift car is locked on a guide rail when the lift car is moved abnormally in the door opening area of an elevator, the lift car is prevented from moving abnormally, the special device can ensure that passengers enter and exit from the elevator safely, and the passengers are protected. The device is designed in a mechanical and electrical integration mode, has the advantages of automatic testing, automatic recognition, rapid response and short brake distance, and plays an important role in preventing elevator shearing and extrusion and other potential safety hazards.
Description
Technical field
The present invention relates to the anti-mobile device of a kind of car.
Background technology
At present, along with social progress, people's living standard constantly improves, and the use of elevator is more and more general, and most of lift cars usually occur abnormal mobile, has the potential safety hazards such as elevator shearing, extruding.
Elevator operative installations, is all the movement device while exceeding the speed limit for detection of lift car, is precarious position and drives brake device for elevator action to make deceleration of elevator stop when it can only detect elevator overspeed; But slowly move for the elevator low speed when dangerous occur, the elevator governor of prior art cannot detect, therefore also just can not produce corresponding action makes deceleration of elevator stop, thus initiation potential.
Such as when the Elevator landing and the in the situation that elevator cab door opens, slowly movement up or down of the caused lift cars of some other X factor such as flat bed quiescence that now lift car is done operation out of control or is not enough to maintain car because of elevator main traction because of certain electric elements fault, in such cases, the speed that lift car moves is very low, not yet reach hypervelocity responsiveness, therefore it is dangerous speed that elevator governor in the past cannot detect the now speed of elevator, on velocity limiter, therefore corresponding actions mechanism can not move yet, therefore also cannot provide action indication to braking element, braking element just can not go to allow the car stop of slow movement yet, if now just there is passenger to be fixedly between elevator cab door and elevator door, lift car movement up or down will likely cause the injury of shearing to passenger, when serious, can cause passenger's death.
Summary of the invention
Technical matters to be solved by this invention is for the defect in above-mentioned background technology
,provide a kind of simple in structure and can detect car and move, thereby guaranteed the anti-mobile device of car of elevator safety wish row.
The present invention is for solving the problems of the technologies described above by the following technical solutions:
The anti-mobile device of car, comprises start unit, reset unit, control unit, power module, and this device also comprises for detection of the electric detecting unit of car amount of movement with for the drag unit of 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 for detection of the situation of closing of car position and the Room, gate, for detection of operation conditions operation contactless switch and the braking contactor of elevator.
Preferably, described power module is for being arranged on the crossbeam of car.
Preferably, described power module is UPS.
Adopt after such scheme, the invention has the beneficial effects as follows:
This device can be used for all kinds of all kinds of vertical lifts that guide rail is sense of motion of take, with sensor detecting and magnet switching mode, make to be arranged on the device action on lift car, can when the improper mobile car in door-opened elevator region, lift car be locked on guide rail, in electromechanical integration mode, design, there is automatic detection, automatically identification, response is quick, the advantage that braking distance is short, effectively prevent the potential safety hazards such as elevator shearing, extruding, brought guarantee to passenger's safety.
Accompanying drawing explanation
Fig. 1 is system architecture schematic diagram of the present invention.
The specific embodiment
Below with reference to accompanying drawing, technical scheme of the present invention is elaborated.
This device can be used for all kinds of all kinds of vertical lifts that guide rail is sense of motion of take, with sensor detecting and magnet switching mode, make to be arranged on the device action on lift car, can when the improper mobile car in door-opened elevator region, lift car be locked on guide rail, in electromechanical integration mode, design, there is automatic detection, automatically identification, response is quick, the advantage that braking distance is short, effectively prevent the potential safety hazards such as elevator shearing, extruding, brought guarantee to passenger's safety.
Specific embodiment is as follows: as shown in Figure 1: the anti-mobile device of a kind of car, comprise start unit, reset unit, control unit, power module, this device also comprises for detection of the electric detecting unit of car amount of movement with for the drag unit of 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 for detection of the situation of closing of car position and the Room, gate, operation conditions operation contactless switch and braking contactor for detection of elevator, described power module is for being arranged on the crossbeam of car, and described power module is UPS.
During work, may be in power failure state when elevator door is opened, therefore device is powered by UPS, device is arranged on car, reliably be fixed on the crossbeam of car, when elevator stops or door enters readiness for operation after opening, by sensor, detect car position and the Room, the situation of closing of gate, by operation contactless switch and braking contactor supplementary contact, detect the operation conditions of elevator, work as the Room, gate is opened, system is not sent under the state of operating instruction, car has when mobile, device detects car position amount of movement and surpasses specialized range, send immediately shutoff instruction, electromagnetic start unit action on the anti-mobile device of lift car, discharge the brake facing locking guide rail of 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, by professional repair and maintenance personnel, device is carried out to hand reset, it is normal that elevator recovers.
