24、d determines the interface between moveable parts and the actuation, locking and detection equipment, and defines the basic 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;
25、 criteria and limits for the forces which move and restrain the moveable parts. 2 Normative references The following referenced documents are indispensable for the application of this document.

27、nd 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 the moveable parts of the switch and crossing. The actuation system includes the rods, links and actuators needed to ensure the operation. The actuation sys
28、tem may be either electric, hydraulic, manual etc. 3.1.2 locking device device that ensures the moveable part of the switches 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 enab
29、les the verification of the correct positioning of the moveable part of the switch and crossing. It enables the signalling to 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 vehic
30、le. There are two different trailing devices trailable devices and non-trailable devices 3.1.4.1 trailable devices devices which permit trailing as non-standard operation Licensed Copy: Wang Bin, na, Mon Feb 06 06:06:47 GMT 2006, Uncontrolled Copy, (c) BSIEN 13232-4:2005 (E) 5 In this case, parts of
31、 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 trailing as standard operation. In this case the actuator and locking system permits the trailing of the switches and crossin
32、gs 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 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,
33、 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 operation 3.1.6.1 non-lubricated slide baseplates no lubrication on the slide baseplates is required to ensure the correct
34、 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 lubrication is required to ensure the correct actuation and locking of the switch and crossing NOTE Track lubrication may still be
35、 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 3.1.7.2 switches and switch diamond crossings open position switch rail stands away from its corresponding stock rail by a
36、 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 position does not exist.

This force is measured at the interface between actuator and the throwing or locking device 3.2.2 actuator cap

41、ation 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 system. These
42、 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 placed on the
43、 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 and the corresp
44、onding 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 maximum gap o
45、f 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 and 3. The sa
46、me 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 dimensio
47、n is taken into account during switch point design to avoid derailment Key 1 dgap(either dgap1or dgap2) 2 dtoeFigure 2 Gap of closed switch rail Licensed Copy: Wang Bin, na, Mon Feb 06 06:06:47 GMT 2006, Uncontrolled Copy, (c) BSIEN 13232-4:2005 (E) 8 Key 1 dgapor dtoeFigure 3 Maximum gap of closed

49、this clearance has to be maintained. Longitudinal displacements are taken into account. Key 1 dfootFigure 4 Foot clearance 3.3.6 toe movement, fpmovement of the toe, when moved by the actuator.
