Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
With reference to Fig. 1, Fig. 2, structure of the present invention is, comprises outer chord frame 1, and the riser of outer chord frame 1 has the bolt hole of multiple connecting bolt 14, the transverse slat of outer chord frame 1 is provided with rectilinear orbit 2, and rectilinear orbit 2 is fixedly connected with outer chord frame 1 by screw, packing ring; Be provided with travelling car in rectilinear orbit 2, car body 7 bottom of travelling car is provided with running roller 8 by securing member 11, and travelling car realizes the movement in rectilinear orbit 2 by running roller 8; Rectilinear orbit 2 front end is provided with sensor support plate 3, and on this sensor support plate 3, level is installed with displacement transducer 13;
Be provided with sensor side flange 9 at the front end face of travelling car, sensor side flange 9 is fixedly connected with the car body 7 of travelling car by screw and packing ring; Be installed with reaction magnetic ring 10 in sensor side flange 9 outer face, the push rod of displacement transducer 13 is through stretching in travelling car inner chamber after sensor support plate 3 and reaction magnetic ring 10;
The rear end face of travelling car is provided with connection side flange 12, and connection side flange 12 is fixedly connected with the car body 7 of travelling car by another group screw and packing ring; In connection side flange 12, be provided with bearing 5, bearing 5 is provided with supporting bearing cap 4 and end ring 6, and bearing 5, reaction magnetic ring 10 are coaxially arranged with the push rod three of displacement transducer 13;
