Detailed description of the invention
Below with reference to accompanying drawing, the specific embodiment of the present invention is described in detail.
Fig. 1 shows the overall structure of the rail vehicle obstacle detector of the embodiment of the present invention.
As it is shown in figure 1, the rail vehicle obstacle detector that the present invention provides, including: detection beam assembly,
Flat spring assembly, fixed block, sliding shoe, screw rod and displacement transducer；Detection beam assembly includes detecting beam 7
With fixed part 9, fixed part 9 is symmetricly set on the two ends of detection beam 7, the rail vehicle barrier that the present invention provides
Hindering analyte detection device is along detection beam 7 symmetrical structure, therefore deduces that, the plate spring groups in the present invention
Part, fixed block, sliding shoe, screw rod and displacement transducer are respectively two sets, and rail vehicle detection of obstacles fills
The structure put illustrates as a example by one end of detection beam 7, and the other end in like manner understands.
Fig. 2 is the enlarged drawing detecting beam one end in Fig. 1, and Fig. 3 is the right view of Fig. 2, such as Fig. 2 and Fig. 3
Shown in, fixed part 9 is fixed on detection beam 7, and the one side of sliding shoe 2 is fixing with fixed part 9 to be connected, separately
One side contacts with fixed block 1, and sliding shoe 2 coordinates slip with fixed block 1, Fig. 4, Fig. 5, Fig. 6 and
Fig. 7 shows the structure of sliding shoe 2 and fixed block 1, arranges towards the one side of fixed block 1 at sliding shoe 2
There is slide rail, the chute slided for slide rail is set towards the one side of sliding shoe 2 at fixed block 1, it is preferable that be sliding
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,
Fixed block 1 arranges slide rail, as long as both can coordinate slip to realize stepless heightening journey.The present invention
The fit system using slide rail and chute can improve the kinematic accuracy of sliding shoe 2 and fixed block 1, and both belong to
In electrodeless slip, it is possible to well play the effect guiding and supporting.
Returning Fig. 2, flat spring assembly includes that flat spring 5 and installing plate 11, installing plate 11 are L-shaped structure,
Including integrated horizontal support arm and longitudinal fixed arm, displacement transducer 4 is arranged on support arm,
Fixed arm is fixing with flat spring 5 to be connected, and fixed arm and flat spring 5 is fixed on bearing 6 by bolt.
Preferably, offering the through hole 12 of strip on support arm, flat spring 5 is passed down through through hole 12, plate bullet
Spring 5 can produce displacement in through hole 12 to displacement transducer 4 direction, and flat spring 5 is passed down through this through hole
The part of 12 is fixing with fixed block 1 to be connected, and indeed through bolt, fixed block 1 is fixed on flat spring 5
On.Owing to the width of through hole 12 is less than the width of support arm, therefore, it can make flat spring 5 be formed middle narrow
The structure that two ends are wide, 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, screw rod 3
One end screw in sliding shoe 2, the other end screws in contiguous block 10, drives sliding shoe 2 by rotary screw 3
Slip on fixed block 1, thus complete 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 shoe 2 offers strip circular hole 13,
Circular hole is offered, after sliding shoe 2 and fixed block 1 slide and adjust, by clamping screw 8 on fixed block 1
Through strip circular hole 13 and circular hole, sliding shoe 2 and fixed block 1 are fixed on fixed part 9.Strip is set
After the purpose of circular hole 13 is the relative altitude so that regulation sliding shoe 2 and fixed block 1, can be different
Elevation is fixed.
Returning to Fig. 2, the detection bar of displacement transducer 4 contacts with flat spring 5, is used for detecting flat spring 5
The degree of elastic deformation, when flat spring 5 occurs elastic deformation, detection bar can become according to flat spring 5 is elastic
The degree of shape produces corresponding displacement, and displacement is converted into the signal of telecommunication by displacement transducer, in conjunction with wheel
Speed, the size of barrier can be analyzed, for rail vehicle provide more decision informations.
No matter it should be noted that whether flat spring 5 sends elastic deformation, the detection bar of displacement transducer begins
Contact with flat spring 5 eventually, to guarantee that the very first time detects the elastic deformation of flat spring 5, thus ensure inspection
The precision surveyed.
