Description

The bogies for railway vehicles test board
Technical field
The utility model relates to a kind of rolling stock proving installation, relates in particular to a kind of bogies for railway vehicles test board.
Background technology
The major parameter of rail vehicles bogie comprises vertical stiffness, longitudinal rigidity, lateral stiffness, gyro rigidity, diamond resistant rigidity and revolution moment of friction etc., the size of each parameter and the whether reasonable dynamic property quality that has determined bogie of coupling, in service at circuit, it directly influences the travelling speed of train, the comfortableness that operates steadily and safe reliability.Therefore, each major parameter of rail vehicles bogie is measured accurately and studied is very essential to the parameter of bogie pick-up unit.
The parametric measurement of rolling stock bogie is that the rolling stock bogie is fixed on the special measuring platform.Again at the difference of survey project, corresponding site on tested bogie or the mensuration platform is applied certain power, make it produce corresponding displacement or distortion, respectively according to the size of institute's application of force and the size of the displacement of the mensuration platform that records, promptly can this calculate corresponding stiffness simultaneously.Therefore, bogie is done vertical, vertically, laterally, revolution, when parameters such as diamond resistant rigidity and revolution moment of friction are measured, requirement be used to install and fixedly the mensuration platform of bogie float, promptly measuring platform can move horizontally and rotate under the effect of power neatly, and the frictional resistance and the moment of resistance when moving horizontally and rotating are the smaller the better, and require mensuration platform self to have enough rigidity, could guarantee accuracy like this, thereby obtain parameters such as every rigidity of bogie and revolution moment of friction exactly the measurement that affacts power on the bogie and moment.
At present, the platform that is used for the rolling stock truck parameter measuring is few, and domestic one tame carshop once developed one, and this is measured platform and adopts cylindrical roller to realize rotating, rotate dumbly, be difficult to measure parameters such as gyro rigidity, diamond resistant rigidity, revolution friction force.Moving of horizontal direction then is to realize moving horizontally of a direction by employing V-arrangement chute below measuring platform, and moving horizontally on the both direction then needs three flat boards at least.The V-arrangement chute is secondary to be sliding friction, the whole platform that structure is complicated is from great in addition, and the moment of resistance when frictional resistance when the mensuration platform moves and rotation is all bigger, moves horizontally and rotate all dumb, be difficult to carry out exactly the mensuration of every power value, fail so far after the installation normally to use.
The utility model content
The purpose of this utility model provides a kind of bogies for railway vehicles test board, and this test board simple in structure made handling ease, measures accurately.
The utility model solves its technical matters, the technical scheme that is adopted is: a kind of bogies for railway vehicles test board, the mensuration platform that comprises base, base top, design feature is: base links to each other with the mensuration platform by the floating support seat in bight, specifically being connected to of floating support seat: the bight of base is fixed with bearing plate, be provided with spacing ring near the edge on bearing plate top or the edge, be placed with ball retainer on the bearing plate in the spacing ring, be placed with steel ball in the steel ball chamber of ball retainer.
The end is fixed on the middle part that at least three return rubber strips on the spacing ring are enclosed in ball retainer support plate.
Steel ball top in the steel ball chamber of ball retainer is placed with the ball-and-socket float plate, is placed with the supporting bulb adaptive with the ball-and-socket shape in the ball-and-socket above the ball-and-socket float plate, and the height of supporting bulb is greater than the degree of depth of ball-and-socket, and the top of supporting bulb is connected with the mensuration platform.
Principle of work of the present utility model is: during test the train bogie is fixed on the mensuration platform, by force loading device, to measuring the effect that platform and bogie apply all directions power together.Measuring platform then moves and rotates by producing between floating support seat and the base, pass through displacement measurement apparatus again, measure and measure the displacement that platform moves and rotates, and the size of the power that applies on the adhesion charger, can calculate the various stiffness parameters of bogie.
Compared with prior art, the beneficial effects of the utility model are: owing to measure between platform and the base is by being to be installed on the base at the bottom of the floating support of core with the steel ball " floating ", measure platform in the spacing ring restricted portion, can move and rotate to freedom and flexibility at base upper edge any direction.Suffered resistance is a force of rolling friction when mobile, and its friction force and the moment of resistance are all very little, has guaranteed the accuracy of parameter measurement.After test was finished, the return rubber strip can make the steel ball self-return, and it is extremely convenient to use, and unsteady bearing keeps the unmanaged flexibility state at any time.Simultaneously, unsteady bearing only is made of steel ball, ball retainer, the several parts of spacing ring that it is simple in structure, makes handling ease.
The steel ball chamber of above-mentioned ball retainer is 7, middle one, and 6 of outer rings.7 steel balls of the corresponding placement in 7 steel ball chambeies that are the plum blossom distributions.Can reduce the stressed of each steel ball like this, and the position distribution of 7 steel balls is even.Reduce the hardness requirement of steel ball, increase the serviceable life of steel ball.
Steel ball top in the steel ball chamber of above-mentioned ball retainer with the concrete mode that the mensuration platform links to each other is: steel ball top is placed with the ball-and-socket float plate, be placed with the supporting bulb adaptive in the ball-and-socket above the ball-and-socket float plate with the ball-and-socket shape, the height of supporting bulb is greater than the degree of depth of ball-and-socket, and the top of supporting bulb is connected with the mensuration platform.
Because the supporting bulb can rotate in the ball-and-socket of ball-and-socket float plate, can guarantee to support and be connected closelyr, reliable between bulb and the mensuration platform, and a plurality of steel balls of ball-and-socket float plate under it all can keep excellent contact.To guarantee the stressed even of each steel ball, it is flexible to measure moving with rotation of platform, the steel ball long service life.
The flat board that stretches out bulb is arranged at above-mentioned supporting bulb top, and the supporting bulb is connected with the mensuration platform by this flat board.Be convenient to like this stretching out the plate part of bulb, by the fixedly connected mensuration platform of engage thread.
Above-mentioned mensuration platform and base are rectangle, and the floating support seat is installed on four angles of base.The mensuration platform processing of rectangle, making are tested easy to use easily; The floating support seat is installed on four angles, and both convenient the installation makes the mensuration platform float steadily, reliably again and is supported on the base.
Above-mentioned mensuration platform is the protruding fish-bellied type framework box structure of middle subordinate, is provided with rail groove and the threaded hole that is used for fixing bogie above the mensuration platform.
The mensuration platform of fish-bellied type framework box structure makes and measures platform under the preceding topic that guarantees enough rigidity, with material minimizing, weight saving, reduces manufacturing cost.
The utility model will be further described below in conjunction with the drawings and specific embodiments.
