Description
Technical field
The utility model relates to the speed probe that a kind of field of track traffic rolling stock tests the speed.
Background technology
Installation of sensors, in all kinds locomotive shaft-end, for locomotive provides travelling speed and direction of motion, is the important component part of locomotive safety running.Because locomotive operation accuracy requirement is high, parameter is more, therefore all with 6 passage speed probes, detects locomotive speed at present.
Six current passage locomotive shaft-end speed probes, be photovoltaic principals speed probe, input shaft is connected with tested wheel shaft, tested wheel shaft drives the rotation of sensor input shaft, tested wheel shaft rotating speed equates with input shaft rotating speed, utilize the photoelectric effect of optical-electric module, produce electric impulse signal proportional to vehicle wheel rotational speed, thereby realize the function testing the speed.But because it adopts light activated element, test the speed, in vehicle operating process, often have frequently impact, vibrations, overload, dirt enter etc., this is just had a strong impact on the reception of sensor signal, greatly reduces its reliability.In the situation that interiors of products environment is subject to polluting, have that passage no signal, phase differential are overproof, low speed is lost the phenomenons such as pulse; There is in the running cacophonia phenomenon in its shafting structure; Its hermetically-sealed construction can not effectively prevent entering of dirt, therefore in track traffic, more and more pursues under the prerequisite of high speed, security, must a kind of more reliable, stable, accurate speed probe of invention.
Utility model content
Technical problem to be solved in the utility model is that the wearing and tearing that solve above-mentioned existence, antifouling ability, environment for use require the problem such as high and a kind of locomotive shaft-end speed probe is provided, and makes its more reliable performance, environment for use require lower.
The utility model solves the problems of the technologies described above adopted technical scheme:
Six passage locomotive shaft-end speed probes, comprise cable assembly, end cap, three Hall speed measuring modules, device seat, described Hall speed measuring module comprises permanent-magnet steel, two Hall elements, amplification and rectification circuit, housing, magnet steel, two Hall elements and amplification and rectification circuit are encapsulated in enclosure interior and form double-channel Hall speed measuring module, three Hall speed measuring modules are fixed on device seat, stretch out outside device seat Hall speed measuring module one end, the other end by end cap seal on device seat, Hall speed measuring module is electrically connected by cable assembly and system, to the power supply of Hall speed measuring module and output speed signal.
Better, on above-mentioned Hall speed measuring module housing, band is installed detent mechanism, by detent mechanism is installed, is fixed on device seat, and Hall speed measuring module is changed more convenient like this.
Better, above-mentioned cable assembly comprises cable and connector.
While surveying locomotive rotating speed with locomotive shaft-end speed probe, a speed measuring fluted disc is installed in the rotating shaft of tested rotating speed, speed pickup sensitive surface is near fluted disc, the rotation of fluted disc makes the magnetic resistance of magnetic circuit periodically change with the change of air gap, when tooth top is aimed at Hall element, the magnetic line of force is concentrated through Hall element, can produce larger hall electromotive force, after amplification, shaping, exports high level; Otherwise, when aiming at Hall element at the bottom of tooth, be output as low level; The change frequency of output level can be followed the rotational speed of measure speed gears and be changed, and can determine the rotating speed of measured object.
The utility model has the advantage of: because the utility model no longer adopts photoelectric sensor, and adopt six passage Halls to test the speed, it can reach the strict requirement of testing the speed of locomotive completely, and lower to the requirement of the environment for use of sensor, the pollutants such as the dust in environment, oil, water all can not affect it normally to be used, the seal request that has reduced product, has reduced cost.
The key of the present utility model parts Hall speed measuring module that tests the speed adopts modular form, is convenient to product using on-the-spot rapid-maintenance, replacing, has reduced customer using cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment six passage locomotive shaft-end speed probes.
Fig. 2 is the stereographic map of the utility model embodiment six passage locomotive shaft-end speed probes.
Embodiment
Below in conjunction with accompanying drawing, embodiment is further described the utility model.
As shown in Figure 1 and Figure 2, six passage locomotive shaft-end speed probes are mainly comprised of cable assembly 1, end cap 2, Hall speed measuring module 3, device seat 4.
Above-mentioned device seat 4 is the carrier of whole locomotive shaft-end speed probe, the mechanical interface while being also installation.
Above-mentioned three identical Hall speed measuring modules 3 comprise permanent-magnet steel, two Hall elements, amplification and rectification circuit, housing, magnet steel, two Hall elements and amplification and rectification circuit are encapsulated in enclosure interior and form double-channel Hall speed measuring module, and each Hall speed measuring module 3 can be exported two passage independent signals.Because the existing shaped article of double-channel Hall speed measuring module is sold, therefore at this, be not described in detail.
Above-mentioned three identical Hall speed measuring modules 3 are installed on device seat 4 by mount pad 31 with certain angle, the induction end face of 3 Hall speed measuring modules 3 is exposed to device seat 4 outside surfaces through the Hall speed measuring module hole 41 of device seat 4, can be consistent with the distance of tested fluted disc like this.
Between above-mentioned Hall speed measuring module 3 and device seat 4, adopt O RunddichtringO 5 to seal.
Above-mentioned end cap 2 is installed on device seat 4, forms sealed cavity with device seat 4, holds inner Hall speed measuring module 3 and cable 12; The cable 12 of cable assembly 1 one end is fixed on end cap 2, and internal core is connected with each Hall speed measuring module 3, and other end assembly connector 11 forms electric interfaces, for connecting power supply and output signal.
Under duty, when speed measuring fluted disc rotates, 3 Hall speed measuring modules 3 can be exported totally six channel signals simultaneously, for measuring the speed of rotating shaft.
