Description
Technical field
The utility model is related to a kind of elevator detection technique field, more specifically to it is a kind of can remote monitoring electricity
Terraced limiter of speed calibration equipment.
Background technology
Important component of the elevator as modern infrastructure conveyance system, with national economic development especially real estate
Development and people's living standard raising it is closely related.Elevator governor-safety tongs linked system is in elevator stall
The protection of most critical, wherein, safety component of the limiter of speed as elevator, its effect is that monitoring and controlling the speed of car simultaneously at any time
Protection instruction can be made in elevator overspeed.Therefore, can limiter of speed it is direct to provide correctly protection instruction when accident occurs
It is related to people's Sheng Ming ﹑ property safeties.Limiter of speed is one of important component of lift running safety protection, is also state for a long time
The emphasis of family's forced examination.Therefore in order to improve the security performance of elevator, the related technical specification of security of country is distinctly claimed electricity
The verification that carry out one-off speed at least 2 years in service life of terraced limiter of speed, what August in 2017 came into effect on the 1st
TSG T5002-2017<Elevator maintenance maintains regular ＞ and added for limiter of speed of the service life more than 15 years, annual to carry out
The requirement of governor tripping speed verification.
The requirement verified before correcting for limiter of speed is advised in elevator inspection：Service life reaches the elevator of 2 years, or speed limit
There is the elevator of each regulator site of Yi Chang ﹑ limiter of speeds envelope note damage in device action, should by licensed elevator inspection body or
Elevator production unit carries out responsiveness verification to limiter of speed, and provides verification report by the unit.Inspection rule provide the project
The method of inspection be examine governor tripping speed verification report, compare speed limit nameplate on relevant parameter, judge responsiveness
Whether meet the requirements.
The requirement that No. 2 amendment of elevator verify for limiter of speed is changed to：Should every 2 by the maintaining unit of inspection elevator
Year (limiter of speed for being no more than 15 years for service life) or annual (for speed limit of the service life more than 15 years) carry out one
Secondary governor tripping speed verification, check results should meet the requirements.And occurred according to the requirement method of inspection that rule are examined after correcting
Larger change：First, the verification of limiter of speed can only be implemented by the maintenance unit of elevator, for normal speed less than 3m/s's
Elevator, reviewer also need the every 2 years checking procedures to maintaining unit to carry out an existing field sight and examine ﹑ confirmations.
The requirement of the front and rear inspection rule of correcting is compareed, require should be every 2 years by the maintaining unit of inspection elevator for inspection rule after correcting
(limiter of speed for being no more than 15 years for service life) or annual (for limiter of speed of the service life more than 15 years) carries out one
Secondary governor tripping speed verification, rated speed of lift are less than 3m/s elevator, and reviewer also needs every 2 years to maintaining list
The checking procedure of position carries out an existing field sight and examines ﹑ confirmations.Inspection rule are except increasing service life before inspection rule contrast correcting after correcting
Outside the limiter of speed requirement of verification once every year no more than 15 years, maximum change is that requirement can only carry out school by maintenance unit
Test, inspection body can not be verified, and require that reviewer also needs the every 2 years checking procedures to maintaining unit to carry out
Existing field, which is seen, examines ﹑ confirmations.
Inspection rule after correcting require, have more paid attention to the inspection of limiter of speed check item purpose, and more focus on limiter of speed school
The procedure quality tested, supervision is strengthened to verification quality, meanwhile, definitely and reduce the main body that verification is implemented, add
The Guan Cha ﹑ at scene confirm that this will largely effect on verification with examining the operating efficiency of both sides mechanism, the work for maintenance unit
The time that amount and inspection body examine proposes new challenge.
With the development of elevator, the quantity of elevator is skyrocketed through, and limiter of speed is every traction elevator (current main flow
One of pattern) indispensable safety component, therefore, limiter of speed is verified for quantity, and workload is huge.Secondly limiter of speed leads to
Cross steel wire rope, tensioning wheel forms one of important safety protection system of elevator with safety tongs, first has to stop electricity during verification
Ladder operation, limiter of speed and steel wire rope are separated using instrument, therefore the preparation that field-checking needs is more, time of verification compared with
It is long.Finally, the installation site of elevator governor is different, and general traction elevator is installed on computer room, for machine-roomless lift, limit
Fast device is installed on elevator hoistways and pit, and because installation site is different, the difficulty of field-checking is difficult estimation, when verifying required
Between differ larger.Therefore, the reviewer confirmed according to the method for inspection that rule are examined after correcting, maintenance unit and scene must be simultaneously
Between at the scene, whole process both sides can not carry out other periodic inspection experiment works, and therefore, this need of work expends big
The manpower of amount and time, very big challenge is proposed to the human resources of maintenance unit and inspection body.
Therefore, now need to design it is a kind of can remote monitoring verifying elevator speed limiter device, examine industry for present elevator
In, realize reviewer can not only remote monitoring maintenance unit personnel to elevator governor carry out checking procedure state, and
Parameter and the check results of limiter of speed can also remotely be obtained to judge whether limiter of speed is qualified.
