Description
Technical field
Patent of the present invention is mainly to develop a kind of portable up-running over-speed protection for permanent magnetic synchronous traction machine elevator to survey
Instrument is tried, in order to which elevator reviewer scene is to the reliability of the protection device for over-speed ascending using permanent magnetic synchronous traction machine elevator
Carry out convenient, science inspection.
Background technology
Protection device for over-speed ascending for elevator is mounted on tracking-driven elevator, is reached to a certain degree in ascending for elevator hypervelocity
When make car stop or at least make its speed be reduced to counterweight buffer scope of design a kind of safety guard.It one
As by speed monitoring and stop or cause deceleration two parts to form.Generally use bidirectional speed limiter is monitored as car speed and filled
Put, stop or cause deceleration device to divide the several ways such as safety tongs, rope brake, deadman's brake, be respectively acting on car or right
The positions such as weight, steel-cable suspensioning device, traction sheave.At present, permanent magnetic synchronous traction machine elevator with its excellent performance by absolutely mostly
Number elevator is used, and deadman's brake acts directly on traction sheave or draging near traction sheave as protection device for over-speed ascending
Draw on axle, this brake design has redundancy, meets the condition of deadman's brake.
But existing National Quality Supervision Bureau General of China promulgate " elevator surveillance is examined and periodic inspection rule-traction is strong
Disunity be present to the test method of the protection device for over-speed ascending of elevator in system driving elevator (TSG T7001-2009) ",
Not science, the defects of human factor is more.
（One）Protection device for over-speed ascending for elevator national standard is examined to elevator surveillance and the related of periodic inspection rule will
Ask：
" elevator manufactures and installation safety standard "（GB7588-2003）In 9.10 pairs of elevators protection device for over-speed ascending
Manufacture propose and clearly require with installation, at " elevator code for erection and inspection "（GB/T10060-2011）Middle 5.4.9 is also right
The function reliability of the protection device for over-speed ascending of elevator, which proposes, to be clearly required.In " the elevator that National Quality Supervision Bureau General promulgates
Supervision and inspection and periodic inspection rule-traction and forcibly driving elevator "（TSG T7001-2009）In be related to ascending for elevator surpassed
The inspection of fast protection device mainly has two 2.14 and 8.1, as follows respectively：
| Project and Classification | Inspection content is with requiring | The method of inspection |
| 2.14 sedan-chair Railway carriage or compartment is up Hypervelocity is protected Protection unit B | Nameplate should be provided with car protection device for over-speed ascending, indicates manufacturer's title, model, specifications parameter With type approval test authority identification, nameplate should be consistent with type approval test quality certification content；The manufacture of elevator complete machine is single Position should mark the action test side of car protection device for over-speed ascending on control flow or emergency operation screen Method | Check and inspection protection device for over-speed ascending The type approval test quality certification and nameplate；Mesh Survey the mark situation of action test method |
| 8.1 car It is up super Speed protection Device tries Test | When car speed uplink is out of control, car protection device for over-speed ascending should act, and make car stop or extremely Its speed is set to be reduced to the scope of design of counterweight buffer less；During the device action, an electrically peace should be made Full device acts | Pressed by construction or maintaining unit Carried out according to method as defined in manufacturer Experiment, reviewer's field observation, really Recognize |
（Two）The defects of existing " inspection rule " car protection device for over-speed ascending experimental examination method:
1st, the existing method of inspection is not apparent, disunity.According to National Quality Supervision Bureau General promulgate " elevator surveillance examine and periodically
Inspection rule-traction and forcibly driving elevator "（TSGT7001-2009）, the car protection device for over-speed ascending of elevator tests it
The method of inspection is provided by each elevator manufacturer, causes each elevator manufacturer to have different methods.
2nd, because without the unified method of inspection, the method for inspection that many elevator manufacturers provide, which exists, to be dealt with, it is impossible to
Elevator car ascending overspeed protection device is correctly tested.
3rd, when the up-running over-speed protection reliability test of elevator is done by elevator Inspection Unit, using this method of inspection, not section
Learn, human factor is larger.Present permanent magnetic synchronous traction machine car protection device for over-speed ascending experimental examination method key step is just
It is：The protectors such as necessary safety barrier are set, car zero load is placed in minimum stop, elevator power supply switch is disconnected, removes
Or short circuit envelope star relay, reviewer open brake with manpower, lift car is gradual upwards in the presence of counterweight gravity
Accelerating running, when the speed uplink of car reaches limiter of speed up-running over-speed protection electric switch responsiveness, limiter of speed is up
Overspeed protection electric switch acts, manpower release brake, and can observation car stop or effectively slow down, and be judged with this up super
Whether fast protection device is qualified.This test method human factor is more, and manpower release brake is protected with the up hypervelocity of limiter of speed
It is difficult synchronous to protect electric switch action, and test method is inaccurate, not science.
