Description

A kind of elevator instantaneous kinetic energy measuring device applied in elevator detection
The application is that application No. is the 2015108984465, applying date 20151204, a kind of entitled elevator are automatic Shutdown kinetic energy detection method and device under the average door closing speed of door, the artificial Anhui Special Equipment Test Inst of application division Shen Please.
Technical field
The present invention relates to Automatic door of elevator dynamic security performance detection method and device, more specifically especially a kind of use The detection method and device of shutdown kinetic energy under Automatic door of elevator is averaged door closing speed.
Background technique
The kinetic energy of Automatic door of elevator at closing time and passenger's boarding are closely related safely, cross conference and passenger is directly threatened to pass in and out sedan-chair Safety when compartment be easy to cause in the case where anti-collision protection device failure and wounds.National standard GB7588-2003 " elevator manufacture with Safety standard is installed " the 7.5.2.1.1.2 articles regulation, " the kinetic energy of layer door and its rigidly connected mechanical part, average Measured value or calculated value under door closing speed should not exceed 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 should not exceed 10J " under average door closing speed.
In the prior art, for shutdown kinetic energy, there is no dedicated testing instruments, so that shutdown kinetic energy can not pass through detection It directly obtains.A kind of detection method of reference is given in GB7588-2003, is referred to: a kind of device can be used when measurement, the dress It sets 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 it is easy equipped with one The annulus of sliding, to measure the limit of sports record point for hitting moment.By the corresponding scale value of gained limit point, can be easy to calculate Kinetic energy values out.As it can be seen that this method is that the shutdown kinetic energy of door leaf before shock is converted to spring using spring slam door leaf Elastic potential energy calculates the elastic potential energy after hitting, in prediction on such basis shutdown kinetic energy out.
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.Due to door leaf door closing speed be not it is constant, shutdown curve also there are many, 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, shock moment Door closing speed can not determine that it is average speed after tested, it is obtained be shock moment door closing speed under shutdown Kinetic energy, i.e. instantaneous kinetic energy, practical measuring device is instantaneous kinetic energy measuring device, it is seen that this method can not meet GB7588- Test request in 2003 about 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 to be the measured value or calculated value under average door closing speed.If using 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 It measures, might have the quality of elevator door leaf in elevator factory data, but do not have door leaf and its rigidly connected machinery generally The quality of machine components will not more mark on nameplate, also require elevator manufactory to provide the quality without relevant criterion at present, And the device is mainly used for the data in the safety verification with elevator, non-nameplate mark to be not easy to obtain.If using similar upper Instantaneous kinetic energy measuring device is stated to be tested, it is also difficult to guarantee that the door leaf speed of service is average speed when test, then measure Kinetic energy is also not the kinetic energy under average door closing speed.In GB/T 10059-2009 " elevator test method " and GB/T 10060- The test method of shutdown kinetic energy is not provided in 2011 " elevator codes for erection and inspection ", this makes practical average for Automatic door of elevator The detection of shutdown kinetic energy is difficult to accurately implement under door closing speed.
