ASSEMBLY AND METHOD FOR TESTING POINT MACHINES

摘要

A device under test, such as a point machine, which is screwed to two longitudinal supports, which can be individually moved horizontally and vertically—is provided. Thus, a highly flexible solution is created, because even devices under test having unknown or asymmetric dimensions can be fittingly accommodated and positioned. Linear drives enable highly accurate positioning of the supports, in particular even if the supports are have high inherent weight or are already loaded with the device under test. According to one embodiment, the mechanical system is designed to grasp and/or to lift a mounting cart by means of the supports, on which mounting cart the device under test is fastened by screwing. This provides the advantage that the device under test can be tested while mounted directly to the mounting cart without separate transferring and screwing of the device under test being required.

主权项

1. An assembly for testing point machines,
having at least one receptacle device comprising:
at least two supports which are adapted for receiving a point machine as a specimen, or for receiving a mounting truck on which a point machine as a specimen is mounted; anda mechanism which is adapted for displacing the supports both in the horizontal direction and in the vertical direction; having a test bed which disposes of a force generator which is adapted for applying counterforces to the specimen while the specimen on the test bed performs actuation procedures, on account of which the test bed is adapted for adjusting and/or testing forces which are generated by the specimen; and wherein the force generator and the mechanism in mechanical and electrical terms are mutually independent such that the supports are displaceable without being influenced by the test bed or by the force generator, on account of which a predefined coupled position between the specimen and the force generator is adjustable.
