Description

Prevent accidental movement of elevator cage system
Technical field
This utility model is related to a kind of elevator device, and more particularly, to one kind prevents accidental movement of elevator cage system.
Background technology
Relevant elevator accident causes injures and deaths event to take place frequently at present, and has elevator to be located in an area, and gate is in situation about opening Under, if due to the abrasion of main frame band-type brake, safeguarding that improper or other reasonses lost efficacy it is impossible to stop stop main frame completely, cause car to occur It may be possible to low speed accidental movement, now easily there are heavy casualties if any personnel in the door area that gate is opened in accidental movement Accident.In view of this it is necessary to be directed to above-mentioned situation, special exploitation one kind has the accidental movement of elevator cage system that prevents, and protects The personal safety of barrier elevator passenger.
Utility model content
The purpose of this utility model is, provides one kind to prevent accidental movement of elevator cage system.This utility model has Compact conformation, adjust flexible feature it is adaptable to compact construction structure.
For solving above-mentioned technical problem, the technical scheme that this utility model provides is as follows: one kind prevents lift car unexpected Mobile system, including mechanism for monitoring, mechanism for monitoring connects controller, and controller is connected with stop mechanism, and mechanism for monitoring includes setting The electronic over-speed governor put in the position switch on car, being arranged on rope sheave and the sine and cosine being arranged on traction machine output shaft are compiled Code device, described stop mechanism include the bidirectional safety tongs being arranged on cage bottom, the counterweight safety being arranged on counterweight frame, The rail clamping device being arranged on guide rail, the traction machine arranging steel wire braking on a steel cord and being arranged on traction machine are braked Device.
Above-mentioned prevents in accidental movement of elevator cage system, described controller connecting moves monitoring device and brake force Monitoring device, described action monitoring device is also connected with traction machine brake with brake force monitoring device.
Compared with prior art, this utility model includes mechanism for monitoring, and mechanism for monitoring includes the position being arranged on car Electronic over-speed governor on switch, rope sheave and the sine and cosine encoder being arranged on traction machine output shaft, position switch is used for monitoring The relative flat bed position relationship of car, limiter of speed is used for monitoring the relative position in advance door opening or enabling flat bed again for the car And/or the speed of service, for monitoring absolute position in hoistway for the car, sine and cosine encoder just exports sine and cosine encoder Cosine wave signal is originated as the signal of elevator car position, carries out shaping by follow-up digitizer to cosine and sine signal Become square wave output, by the software processes to square wave count pulse, stagewise hoistway advertiser export absolute position signal to Controller, thus realize the absolute position detection to lift car;Three monitoring sensors of mechanism for monitoring are respectively connected with control Device, controller as logic control center, for receipt signal with send control command, drives when position switch monitoring is abnormal Traction machine controller and rail clamping device are braked, the also driving traction machine controller system when sine and cosine encoder monitoring is abnormal Dynamic, drive bidirectional safety tongs, counterweight safety and steel wire braking jointly to be braked when limiter of speed monitoring is abnormal.By This is visible, and this utility model, when detecting car accidental movement, triggers in time and the brake component of elevator is braked, from And ensure the personal safety of passenger.Traction machine brake of the present utility model is also associated with action monitoring device and brake force monitoring Device, for monitoring action situation and the brake force situation of traction machine brake.
Brief description
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the braking principle figure of traction machine brake;
Fig. 3 is the action principle figure of electronic over-speed governor.
Specific embodiment
With reference to embodiment, this utility model is further described.
Embodiment:
One kind prevents accidental movement of elevator cage system, and as shown in Figure 1, including mechanism for monitoring 1, mechanism for monitoring 1 connects Controller 2, controller 2 is connected with stop mechanism 3, position switch 4 that mechanism for monitoring 1 includes being arranged on car, is arranged on rope Electronic over-speed governor 5 on wheel and the sine and cosine encoder 6 being arranged on traction machine output shaft, it is just remaining that sine and cosine encoder exports String ripple signal is originated as the signal of elevator car position, by follow-up digitizer, cosine and sine signal is shaped to Square wave exports, and by the software processes to square wave count pulse, stagewise hoistway advertiser exports absolute position signal to control Device processed, thus realizing the position detection to lift car, described stop mechanism 3 includes the bidirectional safe being arranged on cage bottom Pincers 7, the counterweight safety 8 being arranged on counterweight frame, the rail clamping device 9 being arranged on guide rail, setting steel wire rope on a steel cord Brake 10 and the traction machine brake 11 being arranged on traction machine.Described controller 2 connecting moves monitoring device 12 and system Dynamic monitoring device 13, described action monitoring device 12 is also connected with traction machine brake 11 with brake force monitoring device 13.
Described position switch is used for monitoring the relative flat bed position relationship of car, and described position switch can include light Electric-type leveling switch and multichannel photoswitch, limiter of speed is used for the monitoring of rope speed, when steel wire rope reaches the limit of back speed device When constant speed is spent, limiter of speed trigger command carries out safety arrestment to braking equipments such as safety tongs, and described limiter of speed can include electricity Sub- limiter of speed, resonant mode limiter of speed and centrifugal governor;Sine and cosine encoder (also referred to as rotary coder) is used for monitoring Absolute position in hoistway for the car.Three monitoring sensors of mechanism for monitoring are respectively connected with controller, and controller is as logic Control centre, sends control command for receipt signal with according to preset rules, as shown in Figures 2 and 3, when position switch monitoring When abnormal, driving traction machine controller and rail clamping device are braked, the also driving traction machine control when sine and cosine encoder monitoring is abnormal Device processed is braked, and drives bidirectional safety tongs and counterweight safety to be braked when limiter of speed monitoring is abnormal.As can be seen here, originally Utility model, when detecting car accidental movement, triggers in time and the brake component of elevator is braked, and takes advantage of thus ensureing The personal safety of visitor.Traction machine brake of the present utility model is also associated with action monitoring device and brake force monitoring device, uses Action situation and brake force situation in monitoring traction machine brake.
