Description

A kind of elevator door instantaneous kinetic energy measurement apparatus
The application be Application No. 2015108984465, the applying date be 20151204, a kind of entitled elevator it is automatic Closed the door under the average door closing speed of door kinetic energy detection method and device, the division Shen of the artificial Anhui Special Equipment Test Inst of application 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 In the detection method and device for kinetic energy of being closed the door 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 causes in the case where anti-collision protection device fails and wounds.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 kinetic energy of closing the door so that kinetic energy of closing the door can not be by 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 the corresponding scale value of gained limit point, can easily it calculate Go out kinetic energy values.It can be seen that, this method is to utilize spring slam door leaf, and the kinetic energy of closing the door of door leaf before shock is changed into spring Elastic potential energy, calculates the elastic potential energy after hitting, kinetic energy of closing the door is gone out 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, close the door kinetic energy with Door closing speed and change.Because door leaf door closing speed is not constant, curve of closing the door also has a variety of, door leaf door closing procedure middling speed Spend amplitude of variation very big, corresponding kinetic energy difference amplitude of closing the door 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 closing the door 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 kinetic energy of closing the door " 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 utilizing dynamic Energy formula is directly calculated, 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, will not more be marked on nameplate, and also no relevant criterion requires that elevator manufactory provides the quality at present, And it is difficult to obtain the device is mainly used for the data in the safety verification with elevator, non-nameplate sign.If on similar 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 kinetic energy of closing the door, this causes actual average for Automatic door of elevator The detection of kinetic energy of being closed the door under door closing speed is difficult to accurate implementation.
