Description

A kind of rolling stock lock transfers device performance test bed
Technical field
The utility model belongs to mechanical shift electromagnetism test equipment technical field.
Background technology
Along with China Railway constantly raises speed, transporting safely becomes the problem that receives much attention.Train braking system work reliability of operation plays crucial effects to transporting safely of train.Wherein, the Performance Detection to hem shoe gap automatic regulator is exactly an important development problem.At present, the Performance Detection work of hem shoe gap automatic regulator also rests in the traditional-handwork operations such as Steel Ruler, slide calliper rule mostly.The test cell that have comprise frame, brake cylinder and brake lever mechanism thereof, cushioning mechanism, lock are transferred device pull bar, bearing automatically, are fixed with tested lock on the support and transfer the spacing control stalk of device, still are the semi-hand operation.It detects, and still work capacity is big, and efficient is low, poor accuracy.Kind of test cell are arranged, and it adopts two sensors, transfers the mechanical movement position at device two ends to link to each other with lock respectively, transfers the variable quantity of device length overall in different Test items to calculate the variable quantity of screw rod usable length by measuring lock.Still there are a lot of shortcomings in this test cell: 1. Measuring Time is long.The indicating value of ability read sensor after must waiting lock to transfer device static fully after each braking procedure is finished.Transferring device with ST-600 type lock is example, and once complete test approximately needs 40 braking procedures, adds that the clamping time needs nearly 20 minutes, and the every workday is carried out the test that 25 locks are transferred devices at most, can not satisfy large batch of experimental duties.2. complicated in mechanical structure.Be necessary for each sensor and be equipped with guide rail and connecting device, increased corresponding cost, installation difficulty and rate of breakdown.3. can't guarantee survey precision.Tested lock transfers device general pin that adopts on test cell to connect, also there is certain clearance in being connected between sensor and the movable parts, these gaps are not definite values at every turn, be difficult to estimation, cooperate the lock of gained to transfer device length overall error very big through actual measurement by two sensors, generally between the 0-3 millimeter, change, substantially exceeded the error limit that system can allow.The used position detecting element of TT﹠C system is generally synchrotransmitter or grating sensor.Sensor resistance tocrocking and accuracy of detection are higher with walking, but strict to setting accuracy, for example require the straight-line displacement dimension limit in 0.01mm, unless adopt exclusive guideway to be difficult to guarantee precision like this.The position detecting element that is adopted all is to use grating displacement sensor, grating sensor is lower to installation requirement, general guide rail can guarantee, but grating sensor must be equipped with guide rail, this has just increased the complexity of test cell physical constructions, and because the many serious wear of guide rail reciprocal time are easy to make the displacement straightness accuracy overshoot scope of grating to influence accuracy of detection; Because the highest detection speed of grating sensor is generally less than 1.5m/s,, can make measurement size produce maximum error again if the velocity of displacement of brake cylinder surpasses this value.Existing test desk is difficult to promote, so all can not satisfy the requirement of production and transport situation.
Summary of the invention
The purpose of this utility model provides a kind of rolling stock lock tonality energy test desk, it can imitate rolling stock braking actual conditions, realize the test of lock accent device performance, it is simple in structure, and is simple to operation, speed is fast, the efficient height, it is accurate to detect data, and error is little, alleviated tester's labour intensity greatly, be fit to apply.
The technical solution of the utility model is: a kind of rolling stock lock transfers device performance test bed, comprise frame 1 (seeing accompanying drawing), brake cylinder 14 and brake lever mechanism thereof, automatic cushioning mechanism 2, lock is transferred device pull bar 5, bearing 7, be fixed with lock on the support 13 and transfer device 6 spacing control stalks 8 (more than be prior art), it is characterized in that on support 13, being provided with rotating steadying bar 12, be fixed with ball coral displacement pickup read head 11 on the rotating steadying bar 12, the rear end of the joint of sensor slide rule 10 and brake lever 16 is twisted together, and transfer device 6 to be twisted together mutually, and be provided with the displacement data electromagnetic signal acquisition control circuit and the telltale thereof of this displacement pickup with tested lock.
Above-mentioned support 13 is preferably U type support, and rotating steadying bar 12 is contained on the U type support 13 by rotating shaft and two radial ball bearings on its both sides.
In order to make more reasonable structure, be preferably in sensor slide rule 10 joints and the place of being twisted together, brake lever rear end and transfer device 6 to be twisted together mutually with tested lock by the movable joint 9 that is twisted together.
Above-mentioned brake cylinder 14 is a cylinder, cushioning mechanism is the telescopic automatic cushioning of a cylinder mechanism, cushioning mechanism has 9 U type cushion block and 9 little cylinder blocks thereof that thickness is different, and its pneumatic system comprises cylinder, source of the gas three linked piece, reducing valve, change-over valve, flow regulating valve, pipeline, air pump and control circuit thereof.
The utility model can imitate rolling stock braking actual conditions, can realize that the automatic test or the button of lock accent device performance manually controlled.Brake lever head stroke props up sensor by coupled list and measures.Used the ball bar sensor, guide rail that need not be special has saved in the prior art complex mechanical construction in the collecting sensor signal.Be 6 * 10 its service life under correct installation situation 6Inferior, as transferring the device sensor to calculate for reciprocal 40 times, can measure 150000 locks and transfer device by measuring every lock.The highest detection speed of ball bar sensor is 5m/s, is higher than the detection speed of grating sensor, has improved speed, precision and the reliability of dimensional measurement greatly.Through on-site measurement, parameters such as its repeatable accuracy and resolution all can finely satisfy the test requirements document that lock is transferred device, and the anticorrosive and contaminative of this sensor is also fine, and the life-span is long, fully the adequacy test field requirement.The utility model can overcome the deficiency of prior art, have simple in structure, simple to operation, speed is fast, efficient is high, detect the characteristics that data are accurate, error is little, and alleviates tester's labour intensity.Be fit to apply.
