Description
Technical field
The utility model patent mainly develops a kind of portable up-running over-speed protection tester for permanent magnetic synchronous traction machine elevator, so that the reliability of the on-the-spot protection device for over-speed ascending to adopting permanent magnetic synchronous traction machine elevator of elevator inspector carries out inspection that is convenient, science.
Background technology
Protection device for over-speed ascending for elevator is mounted on tracking-driven elevator, makes car stop when ascending for elevator hypervelocity acquires a certain degree or at least makes its speed be reduced to a kind of safety guard of the scope of design of counterweight buffer.It is generally by speed monitoring and stop or cause deceleration two parts to form.Usual employing bidirectional speed limiter is as car speed control monitor unit, and stop or cause speed reduction gearing to divide several modes such as safety tongs, wire holder, sure brake, acts on car or counterweight, steel-cable suspensioning device, the positions such as traction sheave respectively.At present; permanent magnetic synchronous traction machine elevator with its excellent performance use by most elevator; sure brake acts directly on traction sheave as protection device for over-speed ascending or near on the traction axle of traction sheave, this brake design has redundancy, meets the condition of sure brake.
But in " elevator surveillance inspection and periodical survey rule-traction forcibly driving elevator (TSG T7001-2009) " that the National Quality Supervision Bureau General that China is existing promulgates, disunity is existed to the test method of the protection device for over-speed ascending of elevator; not science, the defects such as human element is more.
(1) protection device for over-speed ascending for elevator national standard and elevator surveillance are checked and the related request of periodical survey rule:
In " elevator manufacture and installation safety standard " (GB7588-2003), the manufacture of the protection device for over-speed ascending of 9.10 pairs of elevators proposes clear and definite requirement with installation, and in " elevator code for erection and inspection " (GB/T10060-2011), 5.4.9 also proposes clear and definite requirement to the function reliability of the protection device for over-speed ascending of elevator.Relate in " elevator surveillance inspection and periodical survey rule-traction and forcibly driving elevator " (TSG T7001-2009) that National Quality Supervision Bureau General promulgates and two 2.14 and 8.1 mainly contained to the inspection of protection device for over-speed ascending for elevator, distinguish as follows:
| Project and classification | Inspection content and requirement | The method of inspection |
| 2.14 car protection device for over-speed ascending B | Car protection device for over-speed ascending should be provided with nameplate, indicate manufacturer's title, model, specifications parameter and type test authority identification, nameplate should conform to type test certification of fitness content; Elevator complete machine manufacturer should mark the action test method of car protection device for over-speed ascending on control panel or emergency operation screen | Check and inspection protection device for over-speed ascending type test certification of fitness and nameplate; The mark situation of range estimation action test method |
| 8.1 car protection device for over-speed ascending tests | When car speed uplink is out of control, car protection device for over-speed ascending should action, makes car stop or at least makes its speed be reduced to the scope of design of counterweight buffer; During this device action, an electric safety device action should be made | Tested by the method for constructing or maintaining unit specifies according to manufacturer, inspector's field observation, confirmation |
(2) defect of existing " inspection rule " car protection device for over-speed ascending experimental examination method:
1, the existing method of inspection is undistinct, disunity.According to " elevator surveillance inspection and periodical survey rule-traction and forcibly driving elevator " (TSGT7001-2009) that National Quality Supervision Bureau General promulgates; the car protection device for over-speed ascending of elevator tests its method of inspection to be provided by each elevator manufacturer, causes each elevator manufacturer to have diverse ways.
2, because do not have the unified method of inspection, the method for inspection that many elevator manufacturers provide exists to be dealt with, and correctly can not test elevator car ascending overspeed protection device.
3, when the up-running over-speed protection reliability test of elevator does in elevator Inspection Unit, adopt this method of inspection, not science, human element is larger.Present permanent magnetic synchronous traction machine car protection device for over-speed ascending experimental examination method key step is exactly: arrange the protective devices such as necessary safety barrier, car zero load is placed in minimum stop, disconnect elevator source switch, remove or short circuit envelope star relay, inspector opens drg with manpower, lift car upwards Accelerating running gradually under the effect of counterweight gravity, when the speed uplink of car reaches velocity limiter up-running over-speed protection electric switch responsiveness, the action of velocity limiter up-running over-speed protection electric switch, manpower release drg, can observe car stop or effectively slow down, judge that whether protection device for over-speed ascending is qualified with this.This test method human element is more, and manpower release drg is difficult to synchronous with the action of velocity limiter up-running over-speed protection electric switch, and test method is inaccurate, not science.
