Definitions
- the invention relates to a point machine with a drive unit, which is connected on the one hand with a fixed housing element and on the other hand with the switch tongues to be adjusted.
- Switch machines of this type are known in a wide variety of designs, the drive unit being mostly electrical or electro-hydraulic, see, for example, EP-A-0 480 303.
- reduction gears are usually provided to provide the relatively high switching forces
- the object of the present invention is to improve a point machine of the type mentioned in such a way that said maintenance is possible with the least possible expenditure on personnel and with the least possible disruption to rail operations while at the same time ensuring that the point machine functions properly.
- a force measuring sensor is arranged between the drive unit and one of its connection points to the housing element and is connected to a monitoring unit via an unmoved signal line.
- This force measuring sensor the monitoring unit of which is expediently arranged, for example, in an interlocking or also directly in the vicinity of the point machine, can be used to make a very simple decision as to whether the described by the Frictional forces in the drive train of the switch reacting forces exerted on the connection point of the drive unit to the housing element exceed a tolerable level. If this is the case, it can be concluded that there is increased contamination or the need for lubrication of the point machine and that the necessary measures can be taken in a targeted manner. The service personnel therefore no longer need to clean and / or lubricate a point machine that still functions perfectly in certain defined time intervals, but can be used specifically where it is actually necessary.
- force measurements of a similar type have already become known in various contexts, although it is generally very difficult to carry out force measurements on moving parts. Such measurements are made more difficult in railway operations by extreme environmental conditions, such as. B. very high or very low temperatures.
- this additional complication is taken into account in that the force measuring sensor is arranged in the manner described and is connected to the monitoring unit via an unmoved signal line, so that mechanical loads on the signal line are practically eliminated.
- the drive unit has a hydraulic cylinder which is connected to the housing element with at least one screw
- the preferably ring-shaped force measuring sensor is held between the hydraulic cylinder and the housing element by the screw tightened with a certain preload force.
- the switch machine shown has a hydraulic cylinder 1, that is part of an electro-hydraulic drive unit (not shown further here) and is connected, for example, to a hydraulic pump via hydraulic connections 2.
- the piston rod 3 of the hydraulic cylinder 1 protrudes on both sides through bores 6 from the housing element 7 and is fixed in clamping caps 4, 5.
- the cylinder 8 can be moved back and forth along the axis 9 in accordance with a pressurization via the hydraulic connections 2 - which are connected to the interiors on both sides of the piston via lines (not shown) in the piston rod 3 and thereby receives a lever 10 of no further interest here With a push rod 11, which is connected to the switch tongues, not shown.
- locking hooks 12 which also fix the end positions of the switch tongues in a manner which is likewise not evident here.
- a force measuring sensor 14 is arranged between the hydraulic cylinder 1 acting as the drive unit or its piston rod 3 and the connection point 13 to the housing element 7 or the clamping cap 4 and is connected via an unmoved signal line 15 to a monitoring unit 16 which the latter can be arranged in the interlocking in a manner not visible here.
- the ring-shaped force measuring sensor 14 here is held by a screw 17 tightened with a certain preload force between the hydraulic cylinder 1 or its piston rod 3 and the housing element 7 or the clamping cap 4, so that the hydraulically initiated movement of the cylinder 8 to the connection point 13 exerted reaction forces can be displayed directly on the monitoring unit 16 or can be checked, for example, if a preset threshold value is exceeded.
- a correspondingly designed force measuring sensor could of course also be switched on on the inside of the clamping cap 4 between the latter and the end of the piston rod 3 and be preloaded by tension.
- a different type, design and arrangement of the force measuring sensor is of course also possible if the connection between the drive unit and the housing element is designed accordingly.
