Description
Technical field
The present invention relates to the detection technique of the rich lattice plate of non-fragment orbit, be specially the insulation detecting method and the insulation detection device of the rich lattice plate of non-fragment orbit.
Background technology
By the rich lattice plate production technology of German non-fragment orbit that the Ministry of Railways introduces, be state-of-the-art in the world at present non-fragment orbit systems technology.Because the characteristics (cable transmission) of German domestic non-fragment orbit circuit signal transmission do not have special requirement to the insulating property of winning lattice plate itself, the insulativity of also not making rich lattice plate certainly detects.Introduce the back for adapting to China's track-circuit signalling transmission feature (rail is the signal transport vehicle), require rich lattice plate must possess the good insulation performance performance.Be applied to the rich lattice plate of non-fragment orbit of Beijing-Tianjin inter-city Line for Passenger Transportation at present, the long 6.45m of plate, the plate face adopts the support rail platform structure of shouldered, is fixed with rail fastening on the support rail platform, is crisscross bar-mat reinforcement in the plate body.For guaranteeing the insulating property of rich lattice plate, inside all adopts plastic clamp or heat-shrink tube mode to insulate to the reinforcing bar node in length and breadth, all passes through the detection (individual node insulation resistance value＞2 megaohms) of 500V megohm meter before the deposit concrete in length and breadth to the insulation of reinforcing bar node.Though adopted above-mentioned insulating to handle, for avoiding in the casting process influence to insulation measures, the integral insulation performance of the rich lattice plate in control cast back comprehensively, according to the requirement of the Ministry of Railways, must be before every module unit plate dispatches from the factory by the integral insulation performance detection.The insulation detecting method that adopts is at present, behind the rich lattice plate moulding by casting, detect carrying out insulativity to the reinforcing bar node in length and breadth again, but because concrete itself has certain electric conductivity, testing result shows, the insulation resistance value of individual node reduces greatly behind the rich lattice plate moulding by casting, if come constant to win the insulating property of lattice slab integral with the insulation resistance value of individual node behind the moulding by casting, the insulation qualification rate of rich lattice plate is extremely low.Think that this existing insulation detecting method can't reflect the rich real insulating property of lattice plate.Therefore, also do not have practicable rich lattice plate insulation detecting method and device at present, do not see relevant bibliographical information yet.
Summary of the invention
The present invention provides the insulation detecting method and the insulation detection device of the rich lattice plate of a kind of non-fragment orbit in order to solve the problem of not rich at present lattice plate insulation detecting method and device.
The present invention adopts following technical scheme to realize: the insulation detecting method of the rich lattice plate of non-fragment orbit, 1, tested rich lattice plate is placed on the smooth test platform; Get two rail of being longer than tested plate and be placed on the support rail platform position of plate, and make rail be positioned at rail clip (this moment, the gauge of two rails equaled 1.435m, i.e. the actual gauge of non-fragment orbit); One end of two rails connects with lead, and from the inductance value L and the effective resistance value R in the other end of two rails test two rails loop, test frequency is selected practical carrier frequency (being the signal frequency of railroad track actual transmissions) for use; 2, rail is shifted out tested rich lattice plate, and with two rails insulation support or insulation suspention, keep gauge 1.435m and make the bottom surface of two rails be positioned at same plane, one end of two rails still connects with lead, from the inductance value L0 and the effective resistance value R0 in the other end of two rails test two rails loop, test frequency constant (promptly still selecting practical carrier frequency for use); 3, calculate the rate of change of inductance and effective resistance: Δ L=(L-L0)/L0, Δ R=(R-R0)/R0; Δ L is between ± 3%, and Δ R is the qualified rich lattice plates of insulating property 10% with interior (promptly less than 10%).The track circuit parameter that influences the signal transmission comprises the rail impedance parameter, and the rail impedance parameter is divided into rail effective resistance and rail inductance again.The bar-mat reinforcement of rich lattice intralamellar part is rich lattice plate insulating property of influence and then the principal element that influences rail effective resistance and inductance.The ultimate principle of detection method of the present invention is by detecting the situation of change that rich lattice plate causes the circuit parameter (effective resistance and inductance) of rail return, the overall performance of the rich lattice intralamellar part insulation measures of reflection indirectly.Therefore, detection method of the present invention is more approaching with actual use, can truly reflect the insulating property of rich lattice plate.The rate of change Δ L of the inductance of specification product and effective resistance, Δ R scope determines it is one of key among the present invention; Scope is too small, and defect rate raises, and causes dead wight loss and waste; Scope is crossed conference and is produced the insulation substandard product.Therefore, the rate of change Δ L of the inductance of specification product and effective resistance, Δ R scope determines it is a difficult problem to those skilled in the art.Rate of change of the present invention is to draw by a large amount of experiments expending on the basis of substantial contribution.During experiment, lay with the rich lattice plate of different rate of change and to meet true, the actual non-fragment orbit that requires and be no less than 200 meters, pass to actual transmission signals on the rail, whether the attenuation degree of detected transmission signal conformance with standard.
When the inductance L 0 of the inductance L when test has rich lattice plate, effective resistance R and simple rail, effective resistance R0, the surrounding enviroment that guarantee test are identical, as on identical test platform, carrying out,, guarantee the accuracy of test to reduce the influence of environmental factor to test structure.
Effective resistance and the inductance of measuring rail return can adopt multiple known surveying instrument, the ZL5 intelligent LCR measuring that can adopt Shanghai Instrument Research Institute to produce at least.
The length of described rail is as long as be longer than plate body slightly.The length of rich lattice plate is generally at 6.45 meters, and test slightly is longer than Bo Geban with rail, desirable 7～8 meters.Because what calculate is the variable quantity (difference) of inductance and effective resistance, therefore different rail length can not impact testing result.
The insulation detecting method novelty of the rich lattice plate of non-fragment orbit of the present invention, uniqueness, science, reasonable, simple have been filled up at present the not blank of rich lattice plate insulation detecting method.The rich lattice plate that detects with this insulation detecting method is used for the Beijing-Tianjin inter-city Line for Passenger Transportation, facts have proved that tested rich lattice plate has satisfied actual requirement.
