(1) Multi-functional stop device
Multi-functional limit device can be widely used in construction, port, mining and other industries of lifting, transmission machinery space coordinate control and limit, multi-functional limit device is composed of high-precision large transmission ratio reducer and its output shaft synchronous mechanical memory control mechanism, sensor.
Because the WTAU series of multi-functional limit devices have the characteristics of small size, multiple functions, high precision, adjustable limit, strong versatility and easy maintenance, installation and use adjustment, it should be extremely extensive in construction machinery.
(2) Working principle:
1, the multi-functional limit device is composed of a high-precision large transmission ratio reducer and a mechanical memory control mechanism and sensor synchronized with its output shaft.
2、The displacement signal synchronized by the multi-functional limiter and the controlled mechanism is connected with the input shaft of the limiter after the external pulley speed change, and is converted into the angular displacement signal of the output shaft by the reducer speed change.
3、The memory CAM and microswitch corresponding to the adjustment shaft of the multi-function limit are :1Z1T1WK respectively; 2Z2T2WK; 3Z3T3WK; 4Z4T4WK.
