Description

Stay wire external stay wire displacement sensor Technical Field The invention belongs to the technical field of displacement sensors, and particularly relates to a stay wire external stay wire displacement sensor. Background The stay cord displacement sensor is a sensor for realizing displacement measurement by utilizing the stay cord principle, has the characteristics of simple structure, convenient installation, high precision, good reliability and the like, and is widely applied to the fields of various mechanical displacement measurements, object positioning, automatic control and the like. Along with the development of science and technology, the stay cord displacement sensor is remarkably improved in the aspects of precision, stability, environmental adaptability and the like, and meets the increasingly high industrial measurement requirements. The stay cord in the current stay cord displacement sensor sets up in measuring the dish, and the stay cord does not expose, and silt adheres to on the stay cord, is difficult to clean after getting into in the measuring the dish. The protection level of the existing stay cord displacement sensor is only IP55, and the measuring disc cannot be used in underwater and sediment environments. The scroll spring in the existing stay cord displacement sensor is separated from the measuring disc, and the scroll spring is easy to rust or collision. Disclosure of Invention The invention aims to solve the problems in the prior art and provides a stay wire external stay wire displacement sensor. The invention adopts the following technical scheme: This external stay cord displacement sensor of acting as go-between includes the installing support, the encoder is installed to installing support one side, the installing support opposite side is provided with the measurement carousel, it has the rotation axis to peg graft on the measurement carousel, the one end and the encoder of rotation axis are connected, the winding has the acting as go-between on the measurement carousel outer peripheral face, act as go-between one end and connect the acting as go-between the ring, be provided with the scroll spring in the measurement carousel, scroll spring one end is connected with the rotation axis, the scroll spring other end is connected with the measurement carousel, still install the cantilever crane on the installing support, the mounting panel is installed to cantilever crane one end, be provided with the leading wheel of two symmetry settings on the mounting panel, two form the passageway of acting as go-between the leading wheel, the passageway of acting as go-between passes. Further, the rotating shaft comprises a connecting shaft, a first deep groove ball bearing is sleeved on the connecting shaft, the rotating shaft further comprises a bearing inner seat, one end of the bearing inner seat is a bearing sleeve sleeved on the first deep groove ball bearing, and the other end of the bearing inner seat is a transmission shaft.
