Technical field
The present invention relates to a kind of combination wheel set detecting device of taking turns all array probes, specifically be used for the flaw detection of the online rail of railway, belong to online rail examination technical field.
Background technology
At present, during the online rail examination of railway, generally adopt a probe, probe translation, manual control sampling time or distance, manual monitoring test signal, inefficiency, omission easily.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of combination wheel set detecting device of taking turns all array probes is provided, can realize intensive sampling, effectively prevent omission; The overlap test of wheels can realize repeating the contrast sampling, effectively prevents flase drop; Can realize that rail is online uniformly, quick sampling, detectable signal, and can improve detection efficiency and reliability.
Main solution of the present invention is achieved in that
The present invention mainly is employed in first and forms test wheels with second with surveying to install between the testing wheel with surveying friction wheel with surveying testing wheel, and the test wheels are installed on the alighting gear of adaptive mechanism, connection alighting gear pole on the alighting gear of adaptive mechanism.
Described first adopts wheel that coupling probe is evenly distributed on the test wheel on week with surveying testing wheel or second with surveying testing wheel; Lead on the coupling probe is harness-integrated; Lead is connected on the slip ring of slip ring group in the wire harness, and the slip ring group is connected with the carbon brush group, carbon brush group and total wire joint.
Described coupling probe comprises that single crystal probe, double crystal probe reach near switch.
Described wire harness is by the lead of the lead of single crystal probe, polycrystalline probe, become combination near the line set of switch.
Compared with present technology the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Because homonymy is settled a plurality of wheels, between the wheels, can realize more test function combination; The cross-beta of wheels can be realized intensive sampling, effectively prevents omission; The overlap test of wheels can realize repeating the contrast sampling, effectively prevents flase drop; Preparation rationally intersects wheels and overlapping wheels, the on-line test of realization high speed, and testing vehicle can directly articulate train, or test macro can be directly installed on the corresponding locomotive, really realizes online, real-time wireline inspection; Can realize that rail is online uniformly, quick sampling, detectable signal, and can improve detection efficiency and reliability.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a testing wheel structural representation of the present invention.
The specific embodiment
Following the present invention will combine the embodiment in the accompanying drawing to further describe:
The present invention mainly by wheel week 1, spoke 2, wheel shaft 3, rail 4, slip ring group 5, carbon brush group 6, wire harness 7, coupling probe 8, single, double brilliant probe 9, bus 10, first with surveying testing wheel 11, forming with the alighting gear 15 of surveying testing wheel 13, alighting gear pole 14 and adaptive mechanism etc. with surveying friction wheel 12, second.
Like Fig. 1, shown in Figure 2: of the present invention first with surveying testing wheel 11 or second identical with surveying testing wheel 13 structures.Surveying testing wheel 11 together with first is example.
Test wheel 11 central mounting wheel shafts 3 first with survey, and be provided with spoke 2.First with the wheel of surveying test wheel 11 on week 1 rectangular distribution arrange 12 coupling probes 8; Along with the wheel revolution, combination is surveyed the zone that is contacted successively, in turn, and periodic cycle is surveyed; The realization continuous on-line is surveyed; The test data that coupling probe detects after handling, can be carried out transmission over radio and exchange.Coupling probe 8 comprises single crystal probe, double crystal probe 9 and near switch, single crystal probe, double crystal probe 9 and draw 6 leads near switch and be concentrated into wire harness 7, and the function of every lead and electric terminal are different.Different conductor in the wire harness 7, correspondence are connected on the different slip rings of slip ring group 5, form slip ring group 5 by 6 slip rings.Form carbon brush group 6 by 6 carbon brush.Accomplish classification, cooresponding dynamic the connection by slip ring group 5 with carbon brush group 6 again.Described slip ring group 5 is made up of with the slip ring shaft array the metal slip ring of electric insulating each other, and each slip ring is corresponding to every lead in the above-mentioned wire harness, and function in the different wire harness, the lead that character is identical are connected in parallel on the identical slip ring.6 carbon brush groups 6 are connected with bus 10.Bus 10 is join dependency detecting instrument and background computer again.Above-mentioned slip ring group 5 interior slip rings are electric insulating each other; Carbon brush group 6 each carbon brush are electric insulating each other.Described carbon brush group 6 is formed space array by the carbon brush of electric insulating each other, different carbon brush, corresponding different slip rings, different lead in the different carbon brush connecting bus 10.Bus is join dependency detecting instrument and background computer again.
In the rolling process in wheel week, every group of coupling probe, in turn, in order, detecting periodically rail 4, realize dynamically, sampling rapidly, continuously.It more than is the working process of single testing wheel.With side test the time, can settle a plurality of same testing wheels to form wheels.Through adjusting the initial angle of each testing wheel, constitute syntagmatic, the overlapping or intersection of the coupling probe search coverage before and after can realizing on the testing wheel.Settle a plurality of wheels with side test, between the wheels, can realize more test function combination.The cross-beta of wheels can be realized intensive sampling, effectively prevents omission; The overlap test of wheels can realize repeating the contrast sampling, effectively prevents flase drop.Preparation rationally intersects wheels and overlapping wheels, the on-line test of realization high speed, and testing vehicle can directly articulate train, or test macro can be directly installed on the corresponding locomotive, really realizes online, real-time wireline inspection.
For guarantee that the test wheels roll on the rail of different radians, form test wheels with surveying testing wheel 11 and second with surveying to install between the testing wheel 13 first with surveying friction wheel 12, form wheels by three wheels.By the force of rolling friction of friction wheel, the synchronous rolling power of testing wheel is provided.Initial angle through the adjustment testing wheel can realize cross-beta, overlap test respectively.Between the wheels, can realize the more function combination.
For improving the life-span and the comformability of test wheels; Form the test wheels to first and be placed on the alighting gear 15 that adaptive mechanism arranged with testing wheel 13 and with surveying friction wheel 12 with surveying testing wheel 11, second, connect alighting gear pole 14 on the alighting gear 15 of adaptive mechanism.When needing to detect, drop; Do not do when detecting, pack up alighting gear, whole wheels and rail disengage.The mechanism design of alighting gear can be with reference to the alighting gear of aircraft.
After each highway section, each rail numbered management, the data that each test carriage detects can wait via satellite, accomplished the wireless real-time exchange, did not heavyly leak, and were guaranteeing under the line security, realized economic the detection and brief management.
Coupling liquid generally adopts tap water, when test, to the tap water of coupling, recycles.Adjust the angle and the hydraulic pressure of water spray; In track side surfaces absorption, filtration, regenerative apparatus to water are set; Remove and realize practicing thrift water source, protection ring overseas, can improve the maximum functional stroke of checking system or the comformability of checking system, the demand that overcomes water relies on.
