Background
[0001] An arrangement for a rail traffic switch is provided.
[0002] Rail traffic routes all over the world employ innumerable rail traffic switches which include manually-operated turning devices. These enable points of the switch to be turned from one end position to another.
[0003] The manually-operated turning devices are inexpensive to implement, but their use involves some problems, for instance risks that impair personal safety.
[0004] In the present description, a rail traffic route refers to all traffic routes on which movement takes place guided by rails. Such traffic routes include railways, tramlines, light rails, and underground railways, for instance.
Brief description
[0005] The arrangement of the invention is characterised by what is disclosed in claim 1 . Other embodiments of the invention are characterized by what is disclosed in the other claims. Inventive embodiments are also disclosed in the specification and drawings of this application. The inventive contents of the application may also be defined in ways other than those described in the following claims. The inventive contents may also consist of several separate inventions, particularly if the invention is examined in the light of expressed or implicit sub-tasks or in view of obtained benefits or benefit groups. In such a case, some of the definitions contained in the following claims may be unnecessary in view of the separate inventive ideas. Features of the different embodiments of the invention may be applied to other embodiments within the scope of the basic inventive idea.
[0006] According to an idea, the arrangement comprises a first fastening means fastenable to a switch mover arranged to move a point of a switch, and an electric motor powered by light current, the electric motor being arranged to move the switch mover.
Brief description of the figures
[0007] Some embodiments are explained in closer detail in the accompanying drawings, in which
Figure 1 is a schematic top view of an arrangement arranged in a railway switch, Figure 2 is a schematic top view of a second arrangement arranged in a railway switch, and
Figure 3 is a schematic top view of a third arrangement arranged in a railway switch.
[0008] For the sake of clarity, the figures show some embodiments in a simplified manner. In the figures, like reference numerals identify like elements.
Detailed description
[0009] Figure 1 is a schematic top view of an arrangement arranged in a railway switch. In this case, the railway switch is a so-called "hand operated switch", e.g. a Model 22 switch gear.
[0010] It is to be noted herein that below, a railway switch will be called a "switch". The switch may be e.g. a switch provided with a wedge lock.
[0011] It is yet to be repeated that the arrangement may also be arranged in any rail traffic route other than railway, such as tramlines, light rails or underground railways.
[0012] The switch gear 9 may comprise a counterweight which, when turning the switch, is turned to its other end position. In such a case, the movement is transmitted through a lever mechanism and a pull rod to the points of the switch either via a lock of the switch or directly by means of the rod to both points of the switch.
[0013] The switch gear 9 may be provided in its normal configuration in the switch, but it may also be modified; for instance, the counterweight may be removed when commissioning the arrangement 1 in the switch.
[0014] The switch is provided with the arrangement 1 . The arrangement 1 includes a first fastening means 2 fastened to a switch mover 4 arranged to move a point 3 of the switch. The first fastening means 2 may be implemented in many different ways. It may, among other things, comprise a joint for allowing turning motion.
[0015] In the embodiment shown herein, the switch mover 4 is the aforementioned pull rod of a hand operated switch. However, it is to be noted herein that the switch mover 4 may also be another element included in the switch that is arranged to move either directly or indirectly the point 3 of the switch. In an embodiment, the switch mover is an operating rod of a wedge lock included in the switch. In general, it may be stated that the first fastening means 2 may be arranged in any element that moves along with the point of the switch.
[0016] In the embodiment shown in Figure 1 , the switch mover 4 comprises two second fastening means 6, one such fastening means 6 being fastened to each point 3 of the switch.
[0017] The second fastening means 6 may be implemented in many different ways, but most typically no need exists to modify the fastening between the point 3 and the switch mover 4 when commissioning the arrangement 1 .
[0018] The arrangement 1 further comprises an electric motor 5 arranged between rails 7a, 7b. As viewed in a vertical direction, the motor 5 is preferably arranged above the plane of a lower surface of a sleeper 8. According to an idea, the motor 5 is arranged in parallel with the sleeper 8. According to another idea, the motor 5 is arranged in the plane of an upper surface of the sleeper 8, or above this plane. The rails 7a, 7b constitute a trafficable railway line, and the switch in question is arranged to control the traffic on the railway line.
[0019] The electric motor 5 is arranged to move the switch mover 4 in order to move the switch from one position to another. The electric motor 5 may be fastened by its support member 1 1 e.g. to a sleeper 8, such as to a fixing sleeper for a point fitting, support rail or a corresponding element which is immobile with respect to the rails 7a, 7b. Preferably, the support member 1 1 is fastened to the rail 7a, 7b.
[0020] The electric motor 5 is an electric motor powered by light current. In this description, the concept "light current" refers to single-phase alternating current known as mains current or wall current, as well as to direct current. The nominal effective value of the light current may be 12 V, 24 V, 36 V, 100 V, 1 10 V or 230 V, for instance.
[0021] It is also to be noted that two or even more electric motors 5 may be connected in parallel to turn one and the same switch.
[0022] Most preferably, the electric motor 5 is selected so as to enable it to be used by light current provided in the operating environment. This is e.g. in most parts of Europe and Asia 220 to 240 V alternating current with a frequency of 50 Hz, and in North America 100 to 127 V alternating current with a frequency of 60 Hz. [0023] In the embodiment shown in Figure 1 , the electric motor 5 is a linear motor powered by light current. The linear motor implements linear motion with no need to convert rotational motion into linear motion. Advantages of the linear motor include the linearity of its control, which means that it provides accurate motion, as well as the small number of mechanical parts.
[0024] Some examples of linear motors available for use as the electric motor 5 include the models Electrak 10 or Electrac Pro, manufactured by Thomson. The operating voltage of said linear motors may be 12 V, 24 V or 36 V. It is to be emphasized, however, that other models of linear motors may also be used.
[0025] Any source provided in the vicinity of the switch, such as a lighting system in the switch area, an accumulator of a car or another vehicle, an electric generator or the like, may be used as a power source for the electric motor 5. Of course, the arrangement 1 may comprise a transformer 12 for generating the light current required by an electric motor.
[0026] The arrangement 1 may comprise means for connecting it to a telemonitoring system. This enables the switch to be turned remote- controllably e.g. from a central control room monitoring the railway section in question. The state of the switch, in other words the position in which the switch is, may be identified e.g. by means of a system based on identifying the state of the electric motor 5 or the like. The arrangement 1 connected to a telemonitoring system may quite substantially improve the safety and flow of traffic on the railway section in question.
[0027] The arrangement 1 may comprise a wired or wireless remote control to enable the switch to be turned at a distance from the switch. This may improve the operational safety of the switch. The wireless remote control may be operated e.g. by a remote control which operates at a radio frequency.
[0028] Figure 2 is a schematic top view of a second arrangement arranged in a railway switch.
[0029] Now, the electric motor 5 is arranged outside the railway line formed by the rails 7a, 7b. The electric motor 5 is now an electric motor providing rotational motion and connected to move a transmission device 13, which may be e.g. a pinion rack, a screw guide or the like. [0030] Of course, a linear motor may also be arranged outside the rails 7a, 7b. It is also possible to arrange the electric motor 5 providing rotational motion between the rails 7a, 7b.
[0031] The first fastening means 2 is arranged to move the switch mover 4 through a connecting rod 14. The switch mover 4 is fastened to the points 3 of the switch.
[0032] Figure 3 is a schematic top view of a third arrangement arranged in a railway switch. The arrangement 1 comprises an electric motor 5, which is a linear motor powered by light current. This is arranged in the vicinity of and parallel to a rail 7a. The electric motor 5 is connected via a transmission device 13 to a first fastening means 2 and to the points 3 of the switch. The transmission device 13 may comprise e.g. a mechanism implemented by toothed wheels and pinion racks and/or transmission joints to convert the motion of the linear motor parallel to the rail into motion transverse to the rail.
[0033] It is also to be noted that in the placement of the electric motor providing rotational motion, the direction of its rotation axis may be selected freely, so as to be e.g. parallel, transverse or vertical with respect to the rail.
[0034] The arrangement 1 may be used in several targets of use. A target of use is conversion of a manually operated switch into an electrically driven switch. In such a case, an advantage may be the improved operational safety of the switch, including personal safety, and a possibility to connect the switch to a telemonitoring system. A further advantage is the low construction and operating costs of the system 1 , as compared with an electric turning device powered by three-phase current, e.g. 3~, 400 V AC.
[0035] Another target of use is a temporary use of the switch while constructing a switch, before the new switch has been connected to actual cabling and remote control. An advantage is that the arrangement 1 is easy and quick to install and remove after the switch has been completed.
[0036] In some cases, features disclosed in this application may be used as such, regardless of other features. On the other hand, when necessary, features disclosed in this application may be combined in order to provide various combinations.
[0037] The drawings and the related description are only intended to illustrate the idea of the invention. Details of the invention may vary within the scope of the claims. Reference numerals
