Detailed description of the invention
Below with reference to accompanying drawing, specific embodiment of the utility model is described in detail.
Fig. 1 shows the overall structure of the rail vehicle obstacle detector of this utility model embodiment.
As it is shown in figure 1, the rail vehicle obstacle detector that this utility model provides, including: detection beam assembly, plate bullet
Spring assembly, fixed block, sliding shoe, screw rod and displacement transducer；Detection beam assembly includes detecting beam 7 and fixed part 9, fixed part 9
Being symmetricly set on the two ends of detection beam 7, the rail vehicle obstacle detector that this utility model provides is symmetrical along detection beam 7
Structure, therefore deduce that, flat spring assembly, fixed block, sliding shoe, screw rod and displacement transducer in this utility model divide
Not being two sets, the structure of rail vehicle obstacle detector illustrates as a example by one end of detection beam 7, and the other end in like manner may be used
Know.
Fig. 2 is the enlarged drawing detecting beam one end in Fig. 1, and Fig. 3 is the right view of Fig. 2, as shown in Figures 2 and 3, and fixed part 9
Being fixed on detection beam 7, the one side of sliding shoe 2 and fixed part 9 is fixing to be connected, and another side contacts with fixed block 1, sliding shoe 2 and
Fixed block 1 coordinates and slides, and Fig. 4, Fig. 5, Fig. 6 and Fig. 7 show the structure of sliding shoe 2 and fixed block 1, sliding shoe 2 towards
The one side of fixed block 1 is provided with slide rail, arranges the chute slided for slide rail towards the one side of sliding shoe 2 at fixed block 1, preferably
Ground, slide rail is the slide rail of dovetail configuration, and chute is dovetail groove, it is of course also possible to arrange chute on sliding shoe 2, fixing
On block 1, slide rail is set, as long as both can coordinate slip to realize stepless heightening journey.This utility model uses slide rail and chute
Fit system can improve the kinematic accuracy of sliding shoe 2 and fixed block 1, both belong to electrodeless slip, it is possible to well play
The effect guided and support.
Returning Fig. 2, flat spring assembly includes that flat spring 5 and installing plate 11, installing plate 11 are L-shaped structure, including one
The horizontal support arm of molding and longitudinal fixed arm, displacement transducer 4 is arranged on support arm, and fixed arm is solid with flat spring 5
Fixed connection, is fixed to fixed arm and flat spring 5 on bearing 6 by bolt.Preferably, support arm offers strip
Through hole 12, flat spring 5 is passed down through through hole 12, and flat spring 5 can produce displacement in through hole 12 to displacement transducer 4 direction, and
Flat spring 5 is passed down through that the part of this through hole 12 is fixing with fixed block 1 to be connected, and is fixed by fixed block 1 indeed through bolt
On flat spring 5.Owing to the width of through hole 12 is less than the width of support arm, therefore, it can make flat spring 5 form middle narrow two ends
Wide structure, it is possible to preferably produce elastic deformation.
On flat spring 5, the position connection between support arm and fixed block 1 has contiguous block 10, one end rotation of screw rod 3
Entering in sliding shoe 2, the other end screws in contiguous block 10, drives the sliding shoe 2 slip on fixed block 1 by rotary screw 3, thus
Completing to detect the electrodeless regulation of beam 7 elevation, detection beam 7 and orbital plane remain constant height.In conjunction with Fig. 4 and Fig. 5, sliding
Offer strip circular hole 13 on motion block 2, fixed block 1 offers circular hole, after sliding shoe 2 and fixed block 1 slide and adjust, logical
Cross clamping screw 8 and pass strip circular hole 13 and circular hole, sliding shoe 2 and fixed block 1 are fixed on fixed part 9.Strip circle is set
After the purpose in hole 13 is the relative altitude so that regulation sliding shoe 2 and fixed block 1, can be fixed at different elevations.
Returning to Fig. 2, the detection bar of displacement transducer 4 contacts with flat spring 5, for detecting flat spring 5 elastic deformation
Degree, when flat spring 5 occurs elastic deformation, detection bar can produce corresponding displacement according to the degree of flat spring 5 elastic deformation
Amount, displacement is converted into the signal of telecommunication by displacement transducer, in conjunction with the speed of wheel, can analyze the size of barrier, for
Rail vehicle provides more decision informations.
No matter it should be noted that whether flat spring 5 sends elastic deformation, the detection bar of displacement transducer all the time with plate bullet
Spring 5 contacts, and to guarantee that the very first time detects the elastic deformation of flat spring 5, thus ensures the precision of detection.
