Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of elevator noise detection, in particular to an elevator noise detection device. Background Art
[0002] An elevator is a permanent transportation device that serves several specific floors in a building. Its car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. When people are using the elevator, if the noise inside the elevator is too loud, it will cause discomfort to the users. Therefore, the elevator needs to be noise-detected, and a noise detector is usually used for noise detection.
[0003] In order to improve the accuracy of noise detection in the elevator car, the noise detection device needs to be kept in the middle position of the car and maintained at a height of 1.5 meters from the ground of the car. When the elevator door needs to be opened and closed for noise testing, it needs to be placed 0.24 meters away from the elevator door and the height from the ground is maintained at 1.5 meters. The existing noise detection device requires the user to hold it for detection. When the user maintains a height for a long time for detection, the noise detection device will deviate from the required position due to muscle soreness. In addition, the existing device body is not convenient for fixing the detector. The shaking generated by the elevator during operation will affect the stability of the device body and reduce the applicability of the device body. Therefore, the existing device needs to be improved to meet actual needs. Utility Model Content
