16、ontrolled Copy, (c) BSI EN 13232-4:2005 (E) 3 Foreword This European Standard (EN 13232-4:2005) has been prepared by Technical Committee CEN/TC 256 “Railway applications”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publ
17、ication of an identical text or by endorsement, at the latest by March 2006, and conflicting national standards shall be withdrawn at the latest by March 2006. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, an
18、d supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this European Standard. This series of standards “Railway applications Track Switches and crossings” covers the design and quality of switches and cross
19、ings in flat bottom rails. The list of parts is as follows: Part 1: Definitions Part 2: Requirements for geometric design Part 3: Requirements for wheel/rail interaction Part 4: Actuation, locking and detection Part 5: Switches Part 6: Fixed common and obtuse crossings Part 7: Crossings with moveabl
20、e parts Part 8: Expansion devices Part 9: Layouts Part 1 contains terminology used throughout all parts of the European Standard. Parts 2 to 4 contain basic design guides and are applicable to all switch and crossing assemblies. Parts 5 to 8 deal with particular types of equipment, including their t
21、olerances. These use parts 1 to 4 as a basis. Part 9 defines the functional and geometrical dimensions and tolerances for layout assembly. The following terms are used within to define the parties involved in using the EN as the technical basis for a transaction: CUSTOMER The operator or user of the
22、 equipment, or the purchaser of the equipment on the users behalf. SUPPLIER The body responsible for the use of the EN in response to the customers requirements.

25、nd crossing with moveable parts in respect of the interface. It concerns: rules parameters and tolerances for alternative positions of the moveable parts; criteria and limits for the forces which move and restrain the moveable parts. 2 Normative references The following referenced documents are indi

27、13232-9, Railway applications Track Switches and crossings Part 9: Layouts 3 Terms and definitions For the purposes of this European Standard, the terms and definitions given in EN 13232-1:2003 and the following apply. 3.1 General 3.1.1 actuation system system that ensures the correct movement of th
28、e moveable parts of the switch and crossing. The actuation system includes the rods, links and actuators needed to ensure the operation. The actuation system may be either electric, hydraulic, manual etc. 3.1.2 locking device device that ensures the moveable part of the switches and crossings stays
29、in the desired position. It guarantees the correct position of the moveable part during the passage of the vehicle 3.1.3 detection device device that enables the verification of the correct positioning of the moveable part of the switch and crossing. It enables the signalling to decide whether safe
30、train passage can be guaranteed 3.1.4 trailability ability of actuator and locking systems to permit the trailing of the switches and crossings by a vehicle. There are two different trailing devices trailable devices and non-trailable devices 3.1.4.1 trailable devices devices which permit trailing a

The switches and crossings will only be released for further operation after full inspe
32、ction of switch and actuator. devices which permit trailing as standard operation. In this case the actuator and locking system permits the trailing of the switches and crossings by a vehicle, without damaging any part of it. In both cases the maximum trailing speed is defined 3.1.4.2 non-trailable
33、devices devices which do not permit the trailing of the switches and crossings by a vehicle 3.1.5 single or multiple drives 3.1.5.1 single drive drive operated at one position, i.e. the switch toe 3.1.5.2 multiple drives drives operated at more than one position. In this case there may be either sin
34、gle or multiple locking 3.1.6 lubrication free switch operation 3.1.6.1 non-lubricated slide baseplates no lubrication on the slide baseplates is required to ensure the correct actuation of the switch and crossing. This can be assured by special baseplates, roller systems or other devices 3.1.6.2 lu
35、brication free actuator and locking system no lubrication is required to ensure the correct actuation and locking of the switch and crossing NOTE Track lubrication may still be required, for other reasons. 3.1.7 open and closed position 3.1.7.1 switches and switch diamond crossings closed position s

37、ne or branch line) is not interrupted NOTE An open position does not exist.

These forces can create differential displacemen
42、t between the various components of the switch or crossing 3.3.2.1 switches differential displacement between switch and stock rail is the most important with regard to the switch actuation, locking and detection system. These displacements will be defined in two main places: a) differential toe tip
43、 displacement (y) This is the differential longitudinal displacement between the switch rail and the corresponding stock rail. In order to be able to measure the switch toe displacement, a reference point will be placed on the stock rail. b) differential displacement at the heel block (z) This is th
44、e differential longitudinal displacement between the switch rail and the corresponding stock rail, at the switch heel 3.3.2.2 crossings with moveable parts differential displacement between point or switch rail and the corresponding housing (wing rail) is the most important with regard to the actuat
45、ion, locking and detection system. This displacement is defined at the nose point. In order to be able to measure the swing nose or switch toe displacement, a reference point will be placed on the wing rail 3.3.3 maximum gap of closed switch rail, dgap maximum permissible parallel distance between t
46、he two machined contact faces of the switch and stock rail to give detection. A different value applies in front of the first detection position (dgap1) than in the rest of the machined area (dgap2). See Figures 2 and 3. The same definition applies in principle to crossings with moveable parts 3.3.4
47、 maximum gap at switch toe, dtoe maximum permissible horizontal distance between the two machined contact faces of the switch and stock rail to give safe operation. The dimension is defined at the switch toe. This basic dimension is taken into account during switch point design to avoid derailment K
