Problems solved by technology

The calculation formula is E=1 / 2kx 2 However, according to the standard, the kinetic energy is the measured or calculated value at the average door closing speed, and the test instrument must be measured point by point in the entire door closing track, so theoretically there should be more than N point, not only the test workload is huge, but also the accuracy cannot be guaranteed
[0007] Another disadvantage of DTML-JC is that it cannot describe whether the kinetic energy at the average speed is greater than 10J
[0008] DTML-JC cannot test the corresponding door closing speed when the kinetic energy exceeds 10J, so it cannot judge whether the kinetic energy at this point meets the requirements

Embodiment Construction

[0042] The content of the invention will be further described below in conjunction with the accompanying drawings and examples.

[0043] exist Figure 1 In the embodiment, the force receiver 4 is placed in the running track of the elevator door 1, and the information of the pressure sensor 3 and the speed sensor 5 during the test are sent to the signal processor 2, and the required data are calculated after conversion.

[0044] The pressure sensor 3 can be directly installed on the force-bearing end in contact with the door, or can be installed on the force-receiving sliding block.

[0045] The speed (or displacement) sensor can be installed directly on the slide block 5, and can also be installed on the slide rod 6 linked with the slide block.

[0046] When the slider moves, the speed (or displacement) sensor sends the speed (or displacement) parameter of the door movement to the signal processor 2 .

[0047] When the slider moves, the pressure sensor transmits the output p...

Abstract

The invention discloses a dynamic testing method for elevator door closing kinetic energy. The dynamic testing method is characterized in that the pressure and speed during the door closing process are dynamically tested and the door closing kinetic energy is calculated. According to the dynamic testing method, through distinguishing and calculating the relationship of speed, pressure, displacement and time during the door closing process, a door closing kinetic energy test value during the elevator door closing process is acquired.

Description

technical field [0001] The invention relates to an elevator detection method, in particular to a door closing kinetic energy dynamic test system suitable for elevator horizontal sliding doors. Background technique [0002] In 8.7.2.1.2 of GB7588, it is stipulated that the door closing kinetic energy should not be greater than 10J when measured or calculated at the average door closing speed. [0003] According to 8.7.2.1.1.3 of GB7588, when the door leaf fails to protect the device, [0002] The specified kinetic energy cannot be greater than 4J. [0004] GB7588 stipulates that for non-automatic doors driven by power, under the continuous control and monitoring of the user, when the door is closed by continuously pressing the button or similar methods (continuous operation control), when the door is pressed [0002] When the calculated or measured kinetic energy is greater than 10J, the fastest average door closing speed should not be greater than 0.3m / s (8.7.2.1.2). [0005]...
