It concerns: rules para

26、meters 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 indispensable for the application of this document.

28、nd 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 the moveable parts of the switch and crossing. The actuation system includes the rods,

29、 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 in the desired position. It guarantees the correct position of the moveable part dur

30、ing 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 train passage can be guaranteed 3.1.4 trailability ability of actuator and locking s

31、ystems 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 as non-standard operation BS EN 13232-4:2005+A1:2011EN 13232-4:2005+A1:2011 (E) 6 In

32、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 trailing as standard operation. In this case the actuator and locking system permits the trailing of the s

33、witches 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 the switches and crossings by a vehicle 3.1.5 single or multiple drives 3.1.5.1 single drive drive operat

34、ed 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 operation 3.1.6.1 non-lubricated slide baseplates no lubrication on the slide baseplates is required to

35、 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 lubrication is required to ensure the correct actuation and locking of the switch and crossing NOTE Track lubri

36、cation 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 3.1.7.2 switches and switch diamond crossings open position switch rail stands away from its correspond

37、ing 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 position does not exist.

This force is measured at the interface between actuator and the throwing or locking device 3.2.2 actuator capacity, Fcapmaximum force the act

39、uator 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 parts in their positions, during vehicle passage 3.2.5 locking force, FLforce the locking device guar

These forces can create differential displacement between

42、 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 displace

43、ment (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 the differe

44、ntial 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 actuation, lock

45、ing 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, dgapmaximum permissible parallel distance between the two mac

46、hined 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 maximum g

47、ap 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 design to avoid derailment Key 1 dgap(e
