Problems solved by technology

[0004] Someone uses a spring scale to move the door with manpower. The test number varies with the tension of the spring scale. Not only is the test data unstable, but it is also unsafe.
[0005] TUV abroad and the elevator door impact tester DTML-JC that appeared recently in China use a spring sensor and place the tester at the end of the door closing process. When the two doors are tightened, an impact will be generated on the tester. According to Hooke's law Get F=kx(N), the tester measures the door closing force, but this test method has two disadvantages, one is that the spring will produce a reaction force on the door during the compression process, and the force will increase with the compression of the spring. Large, that is to say, the test instrument itself has a contribution to the measured data, which affects the accuracy of the test; the second defect is because the door closing force test is to test any point in the entire door closing process to find the largest door closing resistance. force, and compare this with the standard value, but due to the limitation of TUV's product structure principle, to meet the standard requirements, more than N points must be tested on the entire door closing trajectory, which is not only a large workload, but also The accuracy is not high, the error is large
[0006] It is inaccurate to replace the measurement of the whole door closing process with a certain point in the door closing process

Embodiment Construction

[0016] The content of the invention will be further described below in conjunction with the accompanying drawings and examples.

[0017] exist Figure 1 In the embodiment, the force receiver 4 is placed in the running track of the elevator door 1. During the door closing process, the elevator door will pass the closing pressure to the information processor through the pressure sensor 3, and the force receiver will also pass the speed through the speed sensor. 5 Pass the speed information to the information processor. The signal processor 2 calculates the required data through conversion.

[0018] The speed calculation value is calculated according to the following formula.

[0019] F(i)=15kF i v i (N)-----(1).

[0020] In the formula, F(i)----calculated value of door closing resistance (N).

[0021] f i ----Test regulation pressure (N), read directly from the sensor by the test.

[0022] v i ----The elevator door closing speed in the test (m / s).

[0023] v i =dl / dt(...

Abstract

The invention relates to a dynamic testing method for elevator's horizontally sliding door closing force, which belongs to the dynamic testing technology of dynamo-electric equipment's door closing force. The method tests the data concerning dynamic door closing force and dynamic door closing speed in a door closing process. Through conversion, the door closing resistance force is obtained when the door closing speed reaches a standardized threshold value; the resistance force is compared with the standardized maximum resistance force of 150N; and when resistance force is beyond the 150N, the door closing force is considered not qualified; and when the resistance force is smaller or equal to the 150N, the door closing force is considered qualified. In the method, each point of the door closing trajectory in the test is considered and the maximum force is detected from these points.

Description

technical field [0001] The invention relates to a dynamic detection method for the door closing force of an elevator. Specifically, it is a method for dynamically testing the door closing resistance force and the speed during the door closing process to calculate the corresponding door closing resistance force when the threshold speed required by the standard is reached. Methods. Background technique [0002] The door closing force of the elevator door is defined in 8.7.2.1.1 of GB7588 as the door closing force should not be greater than 150N. [0003] The current domestic standards and regulations do not specify the test methods for elevator sliding doors. [0004] Someone uses a spring scale to move with the door by manpower, and the test number varies with the tension of the person pulling the spring scale. Not only is the test data unstable, but it is also unsafe. [0005] TUV abroad and the elevator door impact tester DTML-JC that appeared recently in China use a spri...
