BS EN 13232-7:2006+A1:2011EN 13232-7:2006+A1:2011 (E) 5 Part 9 defines the functional and geometrical dimensions and tolerances for l
25、ayout 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 equipment, or the purchaser of the equipment on the users behalf. SUPPLIER The body responsible for the use of the EN in r
26、esponse to the customers requirements.

BS EN 13232-7:2006+A1:2011EN 13232-7:2006+A1:2011 (E) 6 Introduction The requirements of crossings
28、with moveable parts are that they are capable of performing their intended purpose, which is to allow a vehicle to pass the area where the two rails cross with a continuous running edge. That means the wheels of the vehicle are fully supported and guided in the whole crossing area, either in the fac
29、ing or trailing direction. The main criteria for the selection of crossings with moveable parts are: improvement of ride comfort; reduction of noise and vibration; reduction of maintenance; mixed traffic conditions (e.g. train/tram); security against derailment. This last point is particularly impor
30、tant (critical) in diamond crossings. Effectively, as the wheel diameter and the obtuse crossing angle decrease, the distance without guidance (EN 13232-3:2003, 4.2.5) increases. Therefore, to assure the safety of running of the wheel set over the diamond crossing, it is sometimes necessary to desig
31、n the obtuse crossing as moveable. Rules and recommendations for security against derailment in diamond crossings are set down in part 9 of this standard. The crossings with moveable parts shall be designed to withstand all external forces from rolling stock, thermal influences etc. The customer sha
32、ll specify the maximum strains or stresses due to external thermal forces that the crossing with moveable parts has to withstand. Operating, signalling systems, heater systems, load bearing supports, maintainability and safety are all major factors which should be taken into account during the desig
33、n. The performance criteria shall be based on information given by the customer. The design and selection of types of crossings with moveable parts will be influenced by axle loads, frequency of traffic and speed.

34、 is: to establish a working terminology for crossings with moveable parts, which means crossings with moveable parts to close the gap of the running edge, and their constituent parts, and identify the main types; to list the minimum informative requirements for the manufacture of crossings with move
35、able parts and/or their constituent parts; to formulate codes of practice for inspection and tolerances for crossings with moveable parts and/or their constituent parts; to establish the limits and extent of supply; to list the method by which crossings with moveable parts and their constructional p
36、arts should be identified and traced; to list the different and varying ways by which crossings with moveable parts can be described, using the following parameters: geometry of crossings; types of construction; performance requirements; design criteria; tolerances and inspection. 2 Normative refere

These are crossing with moveable point (see Figure 1) and crossing with moveable wing rails (see Figure 2). In both
43、cases: The wings and vee support can be: saddle (cast, welded, machined); assembled (made of different rail profiles, e.g. standard rail, asymmetric low section, symmetric thick web section etc.). The vee can be: monobloc (cast, welded, machined); assembled (made of different rail profiles, e.g. sta
44、ndard rail, asymmetric low section, symmetric thick web section etc.). Rail profiles shall be according to EN 13674-1 and EN 13674-2. In the case of a crossing with moveable point: point may or may not contain a longitudinal sliding area; vee of point and splice rail may be coupled by bolting, weldi
45、ng or fabricated out of a monobloc and welded to their respective adjacent legs. For example see Figures 3, 4 and 5. In the case of a crossing with moveable wing rails a longitudinal sliding area is not required. Other types of construction and their requirements shall be agreed between customer and
46、 supplier. 3.2 Obtuse crossings with moveable parts The main type of obtuse crossing with moveable parts is the switch diamond crossing (see Figure 6). The wing and switches rails support can be: BS EN 13232-7:2006+A1:2011EN 13232-7:2006+A1:2011 (E) 9 saddle (cast, welded, machined); assembled (made
47、 of different rail profiles, e.g. standard rail, asymmetric low section, symmetric thick web section etc.). The wing rail can be: monobloc (cast, welded, machined); assembled (made of different rail profiles, e.g. standard rail, asymmetric low section, symmetric thick web section etc.). Switch diamo
48、nd crossings can be used in obtuse crossings with or without single or double slips. Rail profiles shall be according to EN 13674-1 and EN 13674-2. 3.3 Materials The materials used shall be defined at least by their respective EN or by their mechanical and chemical characteristics in the non-existence of an EN. The grade and specification of rails to be used shall be specified by the customer and shall comply with EN 13674-1, EN 13674-2, prEN 13674-3 and EN 13674-4. All bolts and other fixing devices shall be minimum grade 5.6. All other blocks and fittings
