Facts have proved work with guaranteeing pivoting support long lifetime, high reliability, reduce that except designing and adding the proper mass that improves pivoting support man-hour, reasonably operation maintenance is also very important because the benefit that unpredictable inefficacy brings is lost.In running, monitor the running state of pivoting support in real time, for pivoting support maintenance and maintenance are submitted necessary information, can prolong the service life of pivoting support to greatest extent, improve the operational reliability of pivoting support, also can avoid the loss even the bust of the economic and social benefit that the pivoting support catastrophic failure brings simultaneously.
Summary of the invention
Originally the objective of the invention is to propose a kind of intelligent pivoting support of compact structure of interplantation sensor, can on-line monitoring pivoting support operation health and fitness information, safeguard and maintenance provides reference information for pivoting support, avoid catastrophic failure.
Technological scheme of the present invention is as follows:
A kind of intelligent pivoting support of interplantation sensor, comprise pivoting support, pivoting support comprises moving-coil, fixed circle and one or arranges raceway more, also comprises at least two radial displacement transducers, shaft position sensor support, at least two axial displacement transducers and temperature transducer; Described two radial displacement transducers are installed in the diverse location of deciding circle respectively; The shaft position sensor support is arranged on the pivoting support side, and at least two axial displacement transducers are installed on the shaft position sensor support, is connected with temperature transducer in every row's raceway.
At least be connected with a temperature transducer in described every row's raceway, described temperature transducer is detachably installed by the circle of deciding of screw thread and pivoting support, and the test lead of temperature transducer probes into the raceway of pivoting support by the temperature transducer mounting hole of offering on the fixed circle.
Described radial displacement transducer is installed on the moving-coil of pivoting support by screw thread, and the probe of radial displacement transducer passes the radial direction through hole of offering on the moving-coil.
Described shaft position sensor is installed on the side of deciding circle of pivoting support by the shaft position sensor support, and the shaft position sensor support is installed by the circle of deciding of screw and pivoting support.
At least near being 90 degree angle positions near the stifled bulb stopper of described pivoting support or its symmetrical position and with stifled bulb stopper, a radial displacement transducer is installed respectively, at least with stifled bulb stopper angle 90 degree and negative an angle of 90 degrees position near an axial displacement transducer is installed respectively.
Because stifled bulb stopper is installed in the vertical position of mainly bearing the tilting moment plane usually during installation, the interior displacement of toppling on the plane of toppling more is concerned about in axial displacement usually, therefore at least with stifled bulb stopper angle 90 degree and negative an angle of 90 degrees position (B and D position) near an axial displacement transducer is installed respectively, with pivoting support moving-coil one end face serves as to detect target surface, according to the actual conditions needs, other positions installation shaft position sensor that also can use the same method.
Consider that pivoting support may do the radial displacement of different direction under the different direction radial force, at least near spending angle positions (B or D position) near stifled bulb stopper or its symmetrical position (A or C position) and with stifled bulb stopper 90, a radial displacement transducer is installed respectively, according to the actual conditions needs, other positions installation radial displacement transducer that also can use the same method.
The invention has the beneficial effects as follows:
The present invention implants pivoting support with sensor, forms the intelligent pivoting support of implanted sensor.Compact structure, easy to assembly, health and fitness information in can on-line monitoring pivoting support running, for pivoting support is safeguarded and maintenance, prediction pivoting support fault provide reference signal, can effectively improve the pivoting support operational reliability, prolong service life, the economic and social benefit loss of avoiding the pivoting support catastrophic failure to bring.
