Description

A kind of elevator instantaneous kinetic energy measurement apparatus applied in elevator detection
The application is that Application No. 2015108984465, the applying date 20151204, a kind of entitled elevator are automatic Shutdown kinetic energy detection method and device, the division Shen of the artificial Anhui Special Equipment Test Inst of application under the average door closing speed of door Please.
Technical field
It is more specifically especially a kind of to use the present invention relates to Automatic door of elevator dynamic security performance detection method and device The detection method and device of shutdown kinetic energy under the average door closing speed of Automatic door of elevator.
Background technology
The kinetic energy of Automatic door of elevator at closing time and passenger's boarding are closely related safely, cross conference and directly threaten passenger to pass in and out sedan-chair Safety during railway carriage or compartment, easily cause and wound in the case where anti-collision protection device fails.National standard GB7588-2003《Elevator manufacture with Safety standard is installed》The 7.5.2.1.1.2 articles regulation, " kinetic energy of layer door and its rigidly connected mechanical part, average Measured value or calculated value under door closing speed not should be greater than 10J ", the 8.7.2.1.1.2 articles regulation " gate and its rigidly connected The kinetic energy of machine components, measurement or calculated value not should be greater than 10J " under average door closing speed.
In the prior art, do not have special testing instruments for shutdown kinetic energy so that shutdown kinetic energy can not pass through detection Directly obtain.A kind of detection method of reference is given in GB7588-2003, is referred to:A kind of device, the dress can be used during measurement Put including a piston with a scale.On the spring that it is 25N/mm with a spring constant that it, which is acted on, and equipped with one easily The annulus of slip, to determine the limit of sports record point for hitting moment.By scale value corresponding to gained limit point, can easily calculate Go out kinetic energy values.It can be seen that this method is to utilize spring slam door leaf, the shutdown kinetic energy of door leaf before shock is changed into spring Elastic potential energy, the elastic potential energy after hitting is calculated, goes out kinetic energy of closing the door in prediction on such basis.
According to kinetic energy theory, door leaf and its rigidly connected machine components in the case where quality is certain, shutdown kinetic energy with Door closing speed and change.Because door leaf door closing speed is not constant, shutdown curve also has a variety of, door leaf door closing procedure middling speed It is very big to spend amplitude of variation, corresponding shutdown kinetic energy difference amplitude is then bigger, in being tested using the above method, hits the moment Door closing speed can not determine that it is average speed after tested, resulting be hit the moment door closing speed under shutdown Kinetic energy, i.e. instantaneous kinetic energy, actual measurement apparatus is instantaneous kinetic energy measurement apparatus, it is seen that this method can not meet GB7588- Test request in 2003 on shutdown kinetic energy " measured value or calculated value under average door closing speed ".
The 7.5.2.1.1.2 articles and the 8.7.2.1.1.2 articles of GB7588-2003, what is required is door leaf and its rigidity The kinetic energy of the mechanical part of connection, and require it is the measured value or calculated value under average door closing speed.If utilize dynamic Energy formula directly calculates, even if measuring average speed v, the quality m of door leaf and its rigidly connected mechanical part is also inconvenient Measure, elevator dispatches from the factory and might have the quality of elevator door leaf in data, but does not typically have door leaf and its rigidly connected machinery The quality of machine components, it will not more be marked on nameplate, also no relevant criterion requires that elevator manufactory provides the quality at present, And the device is mainly used for the data in the safety verification with elevator, non-nameplate sign to be not easy to obtain.If using similar to upper State instantaneous kinetic energy measurement apparatus to be tested, it is also difficult to ensure that the door leaf speed of service is average speed during test, then measure Kinetic energy is nor the kinetic energy being averaged under door closing speed.In GB/T 10059-2009《Elevator test method》With GB/T 10060- 2011《Elevator code for erection and inspection》In do not provide the method for testing of shutdown kinetic energy, this actual to be averaged for Automatic door of elevator The detection of shutdown kinetic energy is difficult to accurately implement under door closing speed.
