The invention discloses a speed measuring device for passenger traction elevator detection and a using method of the speed measuring device, and relates to the field of elevator detection. A speed measuring device for passenger traction elevator detection comprises a bottom plate and further comprises a supporting guide column fixedly connected to the bottom plate, and a supporting plate is connected to the supporting guide column in a sliding mode; the connecting plate is located on the upper side of the bottom plate, and a second spring is connected between the connecting plate and the supporting plate; according to the tachometer, when speed measurement detection is carried out on the traction passenger elevator, after the interior of the sleeve is pressurized, the connecting plate is pushed to move upwards, a second spring is compressed to generate thrust, then the supporting plate is pushed to drive the tachometer wheel to be tightly attached to the wheel part of the diversion sheave, and therefore the stability of the tachometer for measuring the lifting speed of the traction passenger elevator is improved; and the wheel part of the tachometer wheel is severely abraded due to long-time contact friction with the wheel part of the diversion sheave, so that the tachometer wheel can be quickly disassembled, replaced and mounted.
本发明公开了一种曳引乘客电梯检测用测速装置及其使用方法,涉及电梯检测领域。一种曳引乘客电梯检测用测速装置,包括底板,还包括:支撑导向柱,固定连接在所述底板上,所述支撑导向柱上滑动连接有支撑板;连接板,位于所述底板上侧,所述连接板与支撑板之间连接有第二弹簧;本发明,在对曳引乘客电梯进行测速检测时,通过向套筒内增压后,推动连接板向上移动,压缩第二弹簧产生推力,进而推动支撑板带动测速轮与反绳轮的轮部紧密相贴,从而提高测速器对曳引乘客电梯升降速度测速的稳定性,以及在测速轮的轮部在长时间与反绳轮的轮部接触摩擦会出现严重磨损,便于实现对测速轮进行快速拆卸更换和安装。
