DIN EN 13232-4:2012-01 EN 13232-4:2005+A1:2011 (E) 5 1 Scope This European Standard determines the interface between moveable parts and the actuation, locking and detection equipment, and defines the basic
27、criteria of switches and 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 referen

30、correct movement of the 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 switche
31、s and crossings stays 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 t
32、o decide whether safe 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 w
33、hich permit trailing as non-standard operation DIN EN 13232-4:2012-01 EN 13232-4:2005+A1:2011 (E) 6 In this case, parts of the switch may be slightly damaged. The switches and crossings will only be released for further operation after full inspection of switch and actuator. devices which permit tra
34、iling 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 devices devices which do not permit the trailing of th
35、e 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 single or multiple locking 3.1.6 lubrication free switch
36、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 lubrication free actuator and locking system no lubricat
37、ion 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 switch rail is applied to its corresponding stock rail
38、3.1.7.2 switches and switch diamond crossings open position switch rail stands away from its corresponding stock rail by a defined distance (switch toe opening) 3.1.7.3 common crossings with moveable parts closed position running edge (of main line or branch line) is not interrupted NOTE An open pos

This force is measured at the interface be
40、tween actuator and the throwing or locking device 3.2.2 actuator capacity, Fcapmaximum force the actuator can provide (see Figure 1) 3.2.3 negative force, Fnegforce needed to keep the moveable part at its closed position 3.2.4 retaining force, FRforce, provided by the actuator to keep the moveable p
41、arts in their positions, during vehicle passage 3.2.5 locking force, FLforce the locking device guarantees and applies to the moveable parts in order to keep them at their locked position Key 1 Actuation force 2 Displacement Figure 1 Actuation forces 3.3 Geometrical parameters 3.3.1 stud gap, dstudg
42、ap between the stud supporting surface and the corresponding surface of the moveable part (i.e. switch rail, point rail, wing rail) DIN EN 13232-4:2012-01 EN 13232-4:2005+A1:2011 (E) 8 3.3.2 longitudinal displacement NOTE longitudinal displacements may occur in the switch and crossing area due to th
43、ermal, acceleration and braking forces. These forces can create differential displacement 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
44、 system. These displacements will be defined in two main places: a) differential toe tip 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
45、 placed on the stock rail. b) differential displacement at the heel block (z) This is the 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 a
46、nd the corresponding housing (wing rail) is the most important with regard to the actuation, 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
47、 maximum gap of closed switch rail, dgapmaximum permissible parallel distance between the 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
48、 and 3. The same definition applies in principle to crossings with moveable parts 3.3.4 maximum gap at switch toe, dtoemaximum 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 desi
