Embodiment
The specific embodiment of the present invention is described in detail below with reference to accompanying drawing.
Fig. 1 shows the overall structure of the rail vehicle obstacle detector of the embodiment of the present invention.
As shown in figure 1, rail vehicle obstacle detector provided by the invention, including：Detect beam assembly, plate spring groups
Part, fixed block, sliding shoe, screw rod and displacement transducer；It is symmetrical including detection beam 7 and fixed part 9, fixed part 9 to detect beam assembly
The both ends of detection beam 7 are arranged on, rail vehicle obstacle detector provided by the invention is the edge detection symmetrical structure of beam 7,
Therefore deduce that, fixing flat spring assembly, fixed block, sliding shoe, screw rod and the displacement transducer in the present invention are respectively two sets, rail
To be illustrated exemplified by detecting one end of beam 7, the other end is similarly understood the structure of road vehicle barrier detection means.
Fig. 2 is the enlarged drawing that beam one end is detected in Fig. 1, and Fig. 3 is Fig. 2 right view, as shown in Figures 2 and 3, fixed part 9
Be fixed on detection beam 7 on, the one side of sliding shoe 2 is fixedly connected with fixed part 9, and another side contacts with fixed block 1, sliding shoe 2 and
Fixed block 1, which coordinates, to be slided, 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, the chute slided for slide rail is set in the one side of fixed block 1 towards sliding shoe 2, preferably
Ground, slide rail is the slide rail of dovetail configuration, and chute is dovetail groove, it is of course also possible to chute be set on sliding shoe 2, in fixation
Slide rail is set on block 1, as long as both can coordinate slip to realize stepless heightening journey.The present invention is matched somebody with somebody using slide rail and chute
Conjunction mode can improve the kinematic accuracy of sliding shoe 2 and fixed block 1, and both belong to electrodeless slip, can be good at playing guiding
With the effect of support.
Fig. 2 is returned to, fixing flat spring assembly includes flat spring 5 and installing plate 11, and installing plate 11 is L-shaped structure, including one
The horizontal support arm of shaping and the fixed arm of longitudinal direction, displacement transducer 4 are arranged on support arm, and fixed arm is solid with flat spring 5
Fixed connection, fixed arm and flat spring 5 are fixed on bearing 6 by bolt.Preferably, strip is offered on support arm
Through hole 12, flat spring 5 are passed down through through hole 12, and flat spring 5 can produce displacement in through hole 12 to the direction of displacement transducer 4, and
The part that flat spring 5 is passed down through the through hole 12 is fixedly connected with fixed block 1, fixes fixed block 1 indeed through bolt
On flat spring 5.Because the width of through hole 12 is less than the width of support arm, therefore, flat spring 5 can be made to form middle narrow both ends
Wide structure, it can preferably produce elastic deformation.
Position on flat spring 5 between support arm and fixed block 1 is connected with contiguous block 10, one end rotation of screw rod 3
Entering in sliding shoe 2, the other end screws in contiguous block 10, and slip of the sliding shoe 2 on fixed block 1 is driven by rotary screw 3, so as to
The electrodeless regulation of the detection elevation of beam 7 is completed, detection beam 7 remains constant height with orbital plane.With reference to Fig. 4 and Fig. 5, in cunning
Strip circular hole 13 is offered on motion block 2, circular hole is offered on fixed block 1, after sliding shoe 2 and fixed block 1 slide adjustment, is led to
Cross clamping screw 8 and pass through strip circular hole 13 and circular hole, sliding shoe 2 and fixed block 1 are fixed on fixed part 9.Strip is set to justify
The purpose in hole 13 is to cause regulation sliding shoe 2 with that after the relative altitude of fixed block 1, can be fixed in different elevations.
Fig. 2 is returned, the detection bar of displacement transducer 4 contacts with flat spring 5, for detecting the elastic deformation of flat spring 5
Degree, when elastic deformation occurs for flat spring 5, detection bar can produce corresponding displacement according to the degree of the elastic deformation of flat spring 5
Displacement is converted into electric signal, in conjunction with the speed of wheel, can analyze the size of barrier, be by amount, displacement transducer
Rail vehicle provides more decision informations.
It should be noted that though whether flat spring 5 sends elastic deformation, the detection bar of displacement transducer all the time with plate bullet
Spring 5 contacts, to ensure that the very first time detects the elastic deformation of flat spring 5, so as to ensure the precision of detection.
