Definitions

  • the invention relates to a switch lock according to the preamble of Claim one.
  • a turnout lock that is frequently used in practice is the latch lock.
  • the latch lock consists of a slide rod, one Connecting strap, two locking pawls, two tongue clamps and two Closing pieces.
  • the locking pawls are built into the tongue block, which are attached to the switch tongues.
  • the one on the stock rails clamped locking pieces serve as a support for the Slide rod.
  • This construction leaves a tongue walk in the case a thermal change in length of ⁇ 25 mm.
  • the lateral guidance the slide rod is taken over by the tongue block.
  • the locking pawl is mounted with an eccentric bolt, which is the adjustment of tongue play.
  • the high forces on the jack axis Any blows caused are absorbed in a built-in elastic bushing.
  • the slide rod has two slide rod parts, which in the Center are electrically insulated, so with a built-in track circuit no short circuit is caused.
  • the drive rod usually engages in the middle, but a side attack is also possible.
  • the latch indirectly with the tongue clamp Tongue connected, extends under the rail foot and thus provides the mechanical adhesion.
  • the snaps Lock pawl directly on the locking piece and is by the slide rod firmly fixed in their position.
  • the remote tongue begins to move first.
  • the latch is pulled down and thereby initiates the unlocking of the adjacent tongue.
  • both tongues follow the movement at the same time the pushrod until the tongue that was previously lying on it.
  • the pusher rod will move the pawl to its locked position raised.
  • the tongue now lying on continues to move to the end of the changeover process and is held in this position.
  • the wheel rim exerts a force on the remote tongue. If the construction of the point machine this allows the slide rod to be moved and the tongue to be unlocked, before it follows the movement of the pushrod. In this way the switch can go up to 40 km / h without damage from the wrong side be driven on.
  • a disadvantage of all known switch closures is that for setting relatively high actuating forces are required. Powering peaks can occur when positioning that even damage the switch lock being able to lead.
  • the known switch locks are common very susceptible to longitudinal movements of the switch.
  • Another disadvantage is that the known switch locks are very maintenance-intensive and require a lot of maintenance. Because the individual mutually movable parts of the switch lock are slidable on each other are, is to the displaceability even with lower actuating forces to enable an increased and constant need for greasing.
  • the known switch locks offer only a small amount of Adjustment options to adapt to certain installation situations to enable.
  • the object of the present invention is now a turnout lock to provide the type mentioned at the outset, in which only minor and otherwise essentially constant actuating forces are required and at which the maintenance and greasing effort is minimized.
  • the above task is at the beginning of a switch lock mentioned type according to the invention with the characterizing features of Claim 1 solved.
  • the configuration according to the invention differs considerably from the switch closures known from practice.
  • the usage at least one storage role and the indirect or immediate Rolling off the slide rod on the bearing roller leads to the fact that at least in essentially only rolling friction between the relatively movable Parts of the switch lock occur.
  • due to the special design with the one rolling directly or indirectly on the storage roll Push rod for maintenance and care very little. A constant and extensive greasing is not necessary.
  • Embodiment the use of an angle lever for locking and / or for adjusting the switch tongue, which is on or on the bearing roller rolls.
  • the angle lever is both on the slide rod and on Block hinged. Via the angle lever, which is directly connected to the bearing roller cooperates, there is an indirect rolling of the slide rod the bearing role.
  • the turnout lock according to the invention is very much smooth and has in addition to the articulation points of the angle lever and the Storage of the bearing roller no components sliding on each other.
  • the angle lever is designed and articulated so that it when adjusting the Push rod with its free end during locking or in The switch tongue is locked around the pivot point on the block swings.
  • angle lever has at its free end a downward first tread rolls on the bearing roller during locking. It is understood that the Unlocking in the same way as the locking, only in the opposite Direction. Accordingly, the following, the locking relevant versions accordingly the unlocking process, even if this is not specified in detail.
  • the angle lever not only locks the switch tongue, but also the control of the actuating movement. This is in detail provided that the angle lever when adjusting the slide rod during the adjustment of the switch tongue with one provided on the angle lever second running surface on the bearing roller. As a result, the Angle levers so the entire movement sequence for locking and locking Set up treads that control the switch tongue.
  • the first and the second tread go directly into one another about. It is provided that the two treads in the area of the transition are aligned by approximately 90 ° to one another.
  • the second tread which controls the actuating movement, has an inclination. Starting from the transition, the second tread is inclined such that the switch tongue is raised during the adjustment. This is ensures that the front sliding chairs or similar pads for the Switch tongue can no longer be lubricated.
  • the invention provides that the bearing roller when reaching the open end position of the switch tongue strikes in the leg area of the angle lever. This is particularly so important when manually operating the turnout lock; with motor drives the actuating stroke is usually determined by the actuator. Still is provided that at the free end of the angle lever in the region of the end of the a nose is provided in the first tread, which acts as a stop when reaching serves the maximum locking position.
  • the width of the bearing roller is preferably one Is several times larger than the thickness of the bell crank. This is one Relative movement between the stock rail and the switch tongue and thus the angle lever on the bearing roller in the longitudinal direction of the track given range possible without the function of the Switch closure is impaired.
  • the bearing roller is an adjusting device is assigned, which is an adjustment of the bearing roller in height and / or at a distance from the stock rail. Via the adjustment device can the switch lock according to the invention to different Installation situations can be easily adapted.
  • the Adjustment device on a storage fork on which the bearing roller is mounted A mechanically safe and easy to implement type of adjustment is guaranteed by spacer plates, which if necessary in the area of Storage fork can be inserted or removed.
  • the invention can also be used Turnout lock using the angle lever a tongue turn of at least 150 mm with a travel of the slide rod of at least 200 mm.
  • the slide rod easily be designed such that there is electrical insulation between the stock rails.
  • the switch lock 1 operates during the changeover process a first and a second switch tongue 2, 3 between one first and a second stock rail 4, 5.
