Winterproof Spoorweqwissel / Spoorweqkruisina

Technical description - Operation 5 The patent that may result from this patent application falls in the following European Patent Classifications: E01B7 / 02, E01B7 / 04, E01B7 / 06, E01B7 / 08, B61L5 / 04, B61L5 / 10. For weeks of research at www.espacenet.cor, it appears that the following patents come close to the invention described in this document: CH642698, DE1158538B, SE33420C1, EP0310627B1. The current major players in railway alternation / intersection are: Thyssen Krupp Weichenbau, Butzbacher Weichenbau, Krug Weichenbau, Voest Alpine (UAE), Vossloh, Schwihag. This relates to an invention applied to a railway switch, see Fig. 1. The switch is constructed in such a way that the operation cannot be influenced by winter conditions and does not have to be heated with a switch heater. in contrast to all points currently in use. In patent SE33420C1, the forces caused by the wheels must be absorbed by long arms. This causes large bending forces (and springy action) in the arms. The forces are ultimately transferred to the gravel bed via the central axis in the middle of the sleepers. This results in a large concentration of forces in the center of the sleepers and therefore also in this case an unfavorable load with undesired bending and suspension. The forces here are not distributed over the length of the sleepers. In addition, leakage water can still come under the tilting arm 25 and the movable tongues, which can then freeze, which may hinder the operation of the switch. With the construction described in this document, see Fig. 02, the forces caused by the wheels are directly discharged vertically downwards to the gravel bed and no large bending forces arise in the construction. Moreover, the construction described here is mechanically locked in the two end positions while no sand, snow or ice can enter anywhere. In the construction described here, the switch tongues do not move in a circular arc (radius half track width) as in patent SE33420C1. In the CH642698 patent, the switch tongues are even supported purely by hydraulics. However, hydraulics 1039271 2 has no hold function as opposed to a purely mechanical support as described in this document. Hydraulics sinks slowly due to the internal leak, and therefore cannot be a reliable alternator. This patent also shows CH642698 figures in which the 5 flanges of the track wheels are driven over the rails !!! That is something that should never happen because rail wheels and the rail system are NOT designed for this, and bear witness to poor rail engineering expertise.

Both the straight rail part of the switch and the curved rail part of the switch see Fig. 02 are equipped with three main groups as mentioned below. The switch is equipped with two movable tongues that cannot move horizontally. See fig.02 pos. 58 and pos.8. Fig. 02 shows a switch (switch position straight on) with tongue pos.8 in the lower position and tongue pos. 58 in the upper position. If the switch position "turn left" is to be reached, tongue pos. 58 in the lower 15 position, and tongue pos. 8 in the upper position. It will be clear that the tongues can both never be allowed to stand in the lower position or in the upper position at the same time. Because the two switch tongues move slidingly and adjacent between four fixed conductors (pos. 57, 59 and pos. 6 and 1), it will be clear that snow, drifting snow, ice, black ice, sand, stones etc.

20 has no chance to get between the tongues and rails and adversely affect the operation of the switch, this in contrast to the switches in use now. See fig 02.

The guide of the rod-eccentric (see fig. 9a pos. 1 and pos. 6) are mounted in the crossbar see fig. 11. Force transfer from the wheel rail vehicle takes place via the tongue-eccentric-rod guide-crossbar-gravel bed or via rod guide-cross member-gravel bed, depending on the position of the wheel on the point. For the purpose of locking the tongue, the switch is provided with a locking slide, see Fig. 11a, pos. 01 which with a locking actuator see fig. 11a pos. 05 is being moved back and forth. Each switch tongue has its own locking slider and locking actuator. Both switch tongues are locked in both the lower position and the upper position.

The locking slide serves to lock the locking blocks during locking.

FIG. 04, 05, 06, 07, and 08. Eccentric pos. Pos. On lower and upper rod. 18 and 19 exactly the same horizontal pulling force or pushing force is exerted simultaneously. On the upper rod, eccentric pos. 18, an actuator pos. 07. On the lower rod eccentric pos. 19 also operates an actuator pos. 07. These two actuators pos. 07 are exactly the same size and are placed in the system parallel behind the pump and control valve. It depends on the position of the eccentric pos. 22 and pos. 23 in the tongue pos. 17 which rod eccentric has the most freedom of movement and which has priority for movement.

If in the lower rod eccentric pos. 19 the eccentric items pos. 23 lying horizontally, the lower actuator has pos. 07 no power over moving 10 the switch tongue pos. 17 because that for the lower actuator pos. 07 is a dead end situation.

At that moment it is precisely the top eccentrics pos. 22 vertically. The upper actuator pos. 07 therefore has great power at that moment to move the switch tongue pos. 17.

15 During the movement, those roles are turned around without getting into a dead-end situation along the way. The lower actuator pos. 07 during the movement will gain more and more power over the movement of the switch tongue pos. 17, because the excenters pos. 23 in the lower rod eccentric pos. 19 become increasingly vertical during that movement, and the upper actuator pos. 07 less and less because the excenters pos. 22 in the upper rod eccentric pos. 18 become more and more horizontal during that movement.

In both end positions (switch tongue pos. 17 up or down) there are always eccentric items pos. 22 or pos. 23 vertically. Vertical eccentrics ensure that the switch tongue pos. 17 "locked" The switch tongue pos. 17 is thus locked in both the up position and the down position. There is also pos. 07 another robust locking mechanism pos. 06 intended and designed to adjust the end positions of the tongues pos. 17 really locked. Essentially the tongue is pos. 17 in the final positions so double 30 locked.

If a vertical eccentric is pulled horizontally (or pushed) by the rod eccentric, the vertical movement force in the switch tongue is pos. 17 infinitely high at the start of the movement. That force is used as a breakaway force should the switch tongue pos. 17 6 are frozen! If the switch tongue pos. 17 is well maintained and well lubricated with WSM replacement grease that has been specially developed for railway switches, the switch tongue cannot freeze up.

Here only the operation of the tongue adjustment and locking of the straight rail section of the switch is described in detail, since the operation of the tongue adjustment and locking of the curved rail section is the same. However, all movements occurring in the straight-rail section of the switch occur simultaneously in the curved rail section but are opposite in direction. Two hydraulic actuators are used in this work description. However, these can also be actuators that operate in a non-hydraulic manner. Instead of two actuators, use can also be made of 1 actuator. In the case of the use of 1 actuator, a mechanical differential construction must be used in order to always be able to move the rod eccentric with the same force in 1 direction regardless of the position of the eccentric.

Tongue movement from lower position to upper position: The starting position is tongue lower position, so switch position: straight on. See fig. 12. In this position 20 no force is exerted on the tongue when a rail vehicle drives over it. The tongue is in the lower position and does not touch the wheel of the rail vehicle. (see fig. 09 pos. 08) On the left side of the pistons of actuators pos.

7 and pos. 13 (Fig. 12), the same pressure is applied simultaneously, fed from the same oil pump. The actuators are connected in parallel behind the oil pump. 25 Only the locking actuator fig. 13 pos. 13 (and the locking slide fig. 13 pos. 6) moves to the right. The upper adjustment actuator pos. 4 cannot move yet because it is still locked at that moment by locking block pos. 16 which is in recess BU. (Fig. 12) The lower adjustment actuator, pos. 7 also cannot move to the right because it presses on the dead point of eccentric pos. 23. FIG. 13. As latch pos. 6 further to the right, the locking block pos. 16 in the upper recess of the latch pos. 6. Because the upper adjustment actuator pos. 7 to the right, locking block pos. 16 due to its oblique side from recess BU pressed down into the upper recess of latch pos. 6. Spring pos. 3 is now slightly depressed. FIG. 14. Locking actuator pos. 13, latch pos. 6, upper adjustment actuator pos. 7, house locking block pos. 4 and rod eccentric-up pos. 18 now move to the right with the same speed. Spring pos. 3 is now pressed further. Eccentric-up pos. 22 now turns a little to the right, 5 and therefore lifts tongue pos. 17 up a bit. FIG. 15. Because tongue pos. 17 moves up, eccentric-bottom pos. 23 to the left. As a result, the lower adjustment actuator presses pos. 7 (via housing locking block pos. 5 and eccentric rod under pos. 19) now no longer against the dead end of eccentric under pos. 23. As a result, the lower adjustment actuator gets pos. 7 better grip on 10 eccentric under pos. 23 and can easily turn it further to the left, so that tongue pos. 17 is pushed up further. The lower adjustment actuator pos. 7 now moves to the right faster than the upper adjustment actuator pos. 7. As a result, spring pos. 3 again. When moving the locking actuator pos. Further to the right. 13, latch pos. 6, 15 upper adjustment actuator pos. 7, housing locking block pos. 4 and rod eccentric-up pos. 18, gets upper adjustment actuator pos. 7 less and less grip on turning eccentric-up pos. 22 and the dead point is reached. The upper adjustment actuator pos. 7 therefore cannot move further to the right. The upper adjustment actuator pos. 7 also cannot continue because the end of the actuator stroke has been reached. Shortly thereafter, the end of the actuator stroke has now also been reached for the lower adjustment actuator, and therefore does not move further to the right. Locking block pos. 16 straight above the recess pos. GU. FIG. 16. The pressure on the upper adjustment actuator pos. 7, the lower adjustment actuator, pos. 7 and the locking actuator, pos. 6 still exists. The locking actuator pos. 13 now moves all the way to the right to the end of the actuator stroke. The locking slider presses pos. 6 the locking block pos. 16 in the recess GU, and the lower adjustment actuator is pos. 7, housing locking block pos. 5, rod eccentric-below pos. 19 and the eccentric below pos. 23 and thereby the tongue pos. 17 locked. Vertically, eccentric is under pos. 23 is now in the dead center and can bear the weight of the rail vehicle without the eccentric-under pos. 23 tends to turn.

Tongue movement from upper position to lower position: The starting position is tongue upper position, so switch position: turn left. See fig. 16. In this position, force is exerted on the tongue when a rail vehicle drives over it. The tongue is in the upper position, and can support the force of the wheel of the rail vehicle. On the right side of the pistons of actuators pos. 7 and pos. 13 (Fig. 16), the same pressure is applied simultaneously, fed from the same oil pump. The actuators are connected in parallel behind the oil pump. Only the locking actuator pos. 13 (and the lock slider, item 6) now moves to the left. The lower adjustment actuator cannot move yet, because it is still locked at that moment by locking block pos. 16 pos. which is in recess GU. (Fig. 16) The upper adjustment actuator, pos. 7 also cannot move to the left because it presses on the dead point of eccentric pos. 22.

FIG. 17. As latch pos. 6 further to the left, the lower locking block pos. 16 free. Because the lower adjustment actuator pos. 7 to the left 15, locking block pos. 16 due to its sloping side from recess pos. GU pushed upwards in the lower recess of latch pos. 6. Spring pos. 3 is now pressed slightly. Locking actuator pos. 13, latch pos. 6, lower adjustment actuator pos. 7, house locking block pos. 5 and rod eccentric-below pos. 19 now move to the left with the same speed. Spring pos. 3 is now pressed further. Eccentric-lower pos. 23 now turns a little to the right, and therefore pulls tongue pos. 17 slightly downwards, (fig. 18). 18. Because tongue pos. 17 moves down, turns eccentric-up pos. 22 to the left. As a result, the lower adjustment actuator presses pos. 7 (via housing locking block pos. 4 and eccentric rod below pos. 19) now no longer against the dead point of eccentric-up pos. 22. As a result, the upper adjustment actuator gets pos. 7 better grip on eccentric-up pos. 22 and can easily rotate further to the left so that tongue pos. 17 is pushed down even further. The upper adjustment actuator pos. 7 now moves to the left faster than the lower adjustment actuator pos. 7. As a result, spring pos. 3 again.

FIG. 19. When locking-actuator pos. Moves even further to the left. 13, latch pos. 6, upper adjustment actuator pos. 7, housing locking block pos. 4 and rod eccentric-up pos. 18, lower adjustment actuator pos. 7 less and less grip on turning eccentric-under pos. 23 and the dead point is reached. The lower adjustment actuator pos. 7 therefore cannot move 9 further to the left. The lower adjustment actuator pos. 7 is also not possible because the end of the actuator stroke has been reached. Shortly thereafter, the end of the actuator stroke has now also been reached for the upper adjustment actuator, and therefore does not move further to the left. In this position (see Fig. 19) 5 locking block pos. 16 straight under the recess pos. BU. FIG. 20. The pressure on the upper adjustment actuator pos. 7, the lower adjustment actuator, pos. 7 and the locking actuator still exists. The locking actuator pos. 13 now moves all the way to the left to the end of the actuator stroke. The locking slider presses pos. 6 the locking block pos. 16 10 in the recess BU, and the upper adjustment actuator is pos. 7, housing locking block pos. 4, rod eccentric-up pos. 18 and the eccentric-up pos. 22 and therefore the tongue pos. 17 locked. Vertically, eccentric is above pos. 22 is now in the dead center and is therefore locked without the eccentric-up pos. 22 tends to turn.

Claims (3)

The mechanical switch tongue adjustment device is provided with a unique mechanical double dead point eccentric adjustment that also mechanically locks the upper and lower position of the switch tongue. The mechanical switch-tongue adjustment device is constructed in such a way that a dead-point situation can never arise that makes movement and operation impossible. The mechanical switch tongue adjustment device is suitable for use both in the straight rail section of the switch or junction, and in the curved rail section of the switch or junction. The mechanical double dead point eccentric adjustment is constructed in such a way that the force at the very beginning of the up-movement and the down-movement (output force) of the change-over tongue is very large (high breaking force if completely frozen), while very few input power is needed. The mechanical double dead point eccentric adjustment is constructed in such a way that a very small operating stroke of the adjusting actuator (for example: a hydraulic cylinder) is required. This makes compact construction possible. The mechanical double dead center eccentric adjustment is constructed in such a way that it can support the largest axle train loads on rail vehicles, and can also hold the end positions (high or low) in position. This does not go unnoticed and slowly, as is the case with hydraulic actuators that directly engage the tongue. The mechanical vertical switch tongue adjustment device is provided with a compression spring which is spring-loaded in the end positions of the adjustment device and is depressed during the up and down movement (i.e. all intermediate positions), so that the mechanism always tends to an end position automatically, and never to an end position. intermediate position can “get stuck” if the actuator fails during the adjustment movement. The mechanical switch tongue adjustment device is also provided with a robust mechanical locking device for locking the end positions of the tongues which is actuated with a separate locking actuator (for example: a hydraulic cylinder). The mechanical locking device and the switch tongue adjustment device are constructed in such a way that forces exerted on the switch tongue (caused by the weight of the rail vehicle) are not transmitted to the adjusting actuator and also not to the locking actuator. The construction described here is equipped with two hydraulic actuators. However, these can also be actuators that operate in a non-hydraulic manner. Instead of two actuators, use can also be made of 1 actuator. In the case of the use of 1 actuator, a mechanical differential construction must be used to ensure that the rods 10 eccentric can always move out with the same force 1 direction regardless of the position of the eccentrics. 1039271
