Definitions
- the invention relates to a switch drive with a hydraulic actuating cylinder, which is mechanically coupled to a slide housing connected to a push rod for the switch tongues, and to a locking hook for each of the two end positions of the switch, which engages in a detent in its assigned end position and when initiating the adjustment of the switch can be brought out of engagement with its catch.
- Switch machines of the type mentioned are known for example from DE-B2 19 52 824, DE-B2 26 06 664 or DE-C2 30 20 788.
- the changeover of the switches is generally initiated from an interlocking and, after the changeover has ended, is ended automatically depending on the organs monitoring the end position of the switch tongues, the respective end position mostly being blocked on the push rod.
- this lock it is mostly irrelevant whether the driven turnout should be able to be moved up or not, since the respective turnout drive is preferably designed so that it can be used for both of the above-mentioned variants with as few changes as possible.
- the object of the present invention is to design a turnout drive of the type mentioned at the outset in such a way that the difficulties mentioned are avoided and that, in a structurally simple manner in particular, safe locking and unlocking of the turnout end positions is possible even in harsh environmental conditions without the need for this constructive effort becomes too great.
- a locking lever is provided on the actuating cylinder on the one hand and on the slider housing on the other hand - pivotably mounted and its effective length is variable, the free pivotability of which is provided for connecting the actuating cylinder to the valve housing Stops on the slide housing is limited and which has two cam-like elevations on the side of the slide housing, at each of which in the area of the end positions there is a pivot bolt articulated on the slide housing with an actuating cam, which on the other hand has the catch for the associated locking hook fixed on the housing side.
- the corresponding element (either cylinder or piston rod) of the actuating cylinder moves and rotates the one on the initially fixed push rod or on the one sitting on it Slider housing articulated, latched locking lever around its there Swivel axis. Since the locking lever can be freely pivoted between its stops on the slide housing, the latter is not taken along for the time being, so that the connecting rod that is either permanently connected in the event that the switch cannot be opened, or connected in the case of opening via a releasable coupling device is also not initially taken along.
- each swivel bolt can be snapped into the respective locking hook via a spring-loaded engaging element arranged in the area of the associated end position of the switch, which enables the switch drive to be locked securely in the two end positions.
- the above Engagement elements can be coupled to signaling or testing devices provided in the area of the end positions, which can indicate or report that the respective end position has been properly reached, for example, in a manner that is not particularly interesting here in the signal box or the like. These engaging members are particularly advantageous when the switch drive must definitely be locked in the end positions even at high switch speeds.
- the loading spring of each engagement element can, for example, be arranged fixed to the housing - roller or ball-like elements can be provided at the end assigned to the swivel bolt, which improve the ease of movement of the entire arrangement.
- both swivel latches bear with their actuating cam spring-loaded against the respectively assigned cam-like elevation of the latch lever and that the locking hooks have a beveled contact surface for the latching end of the swivel latches, after overcoming this end under the action of the spring load snaps into the locking hook.
- Another development of the invention also aims in the same direction, according to which the pivotability of the pivot bolts in their unlocked position is limited by stops on the slide housing, so that, particularly in connection with the spring loading described above, the pivot bolts move in the direction of the associated ones cam-like elevations of the locking lever always result in defined positional relationships for the swivel locks and the driving of the slide housing or the push rod in the unlocked position takes place or is additionally supported not only via the stop of the locking lever on the slide housing but also via the stop of one of the swivel locks on the slide housing can be.
- the catch on each of the swivel bolts can be formed by a rotatably mounted roller, which offers advantages overall, in particular with regard to the easy actuation of the switch drive.
- the slot-like recess like the sliding block, has oblique side walls relative to the axis of the locking lever, which, when lying on top of one another in a force-transmitting manner, for adjusting the switch, essentially perpendicular to the direction of movement of the actuating cylinder lie.
- a hydraulic actuating cylinder 2 is arranged, the piston rod 3 is fixed in a manner not shown in the externally placed clamping caps 4, so that when the hydraulic connections 5 are acted upon appropriately via a hydraulic pump (not shown) Cylinder 6 from the left end position shown in FIG. 1 via one in FIG. 2 apparent middle position can be moved into the right end position shown in FIG. 3.
- the connection of the hydraulic connections 5 to the working spaces in the cylinder 6 can run inside the piston rod 3, but is not shown here like the working spaces and the piston itself.
- the actuating cylinder 2 is mechanically coupled to a slide housing 8 which is connected to a push rod for the switch tongues (not shown further), which takes place via a locking lever 9 which is pivotably mounted on the actuating cylinder 2 on the one hand and on the slide housing 8 on the other hand and is variable in its effective length.
- This locking lever 9 is articulated on the one hand to enable the change in the effective length on the side of the actuating cylinder 2 to a sliding block 12 guided in a slot-like recess 10 along the lever axis 11 and on the other hand to a fixed axis of rotation 13 on the slide housing 8, its free pivotability being possible by means of Stops 14, 15 on the slide housing 8 is limited.
- the swivel bolts 18, 19 are mounted on the slide housing 8 so as to be pivotable about axes of rotation 22 and each have a catch 23 on their side opposite the actuating cams 20, 21 with respect to this mounting, which latches cooperate with a locking hook 24, 25, which is fixed on the housing side, and are mounted here as rotatable Rollers 26 are formed.
- Both swivel bolts 18, 19 are spring-loaded in a manner not shown here and, under the effect of this spring load, they rest with their actuating cam 20, 21 on the respectively assigned cam-like elevation 16, 17 of the locking lever 9.
- the locking hooks 24, 25 have chamfered contact surfaces 27 for the catch 23 or the roller 23 forming them here, wherein - with relative movement between the catch hook and catch in the illustration from left to right or vice versa, the roller 26 after overcoming the chamfered contact surface 27 below Effect of the spring load of the corresponding swivel bolt engages in the locking hook or its recess.
- the switch is reset from the position shown in FIG. 3 to the position shown in FIG. 1 in reverse.
- the design of the soft drive according to FIGS. 4 to 6 differs from that according to FIGS. 1 to 3 essentially only in the way of ensuring that the respective pivot bolt 18, 19 is locked in its associated end position in the locking hooks 24, 25.
- the swivel bolts are 18, 19 not spring-loaded in the manner described here in the direction of their actuating cams 20, 21 from the cam-like elevations 16, 17 of the locking lever 9, but are only pressed into the respective recess of the locking hook 24, 25 in the region of their assigned end position by spring-loaded engagement members 30 .
- the latch-side end of each swivel bolt 18, 19 can be snapped into the respective locking hooks 24, 25, as shown in FIGS.
- the engagement members 30 can also be connected or combined in a manner not shown here, for example with test bars or the like for reaching the end position of the point machine, which report the reaching of the respective end position in a manner not shown, for example to an interlocking or the like.
- FIGS. 4 to 6 corresponds entirely to that according to FIGS. 1 to 3 - the same or at least functionally the same parts are also provided with the same reference numerals; with regard to the description of these parts and their function, reference is made to the above explanations relating to FIGS. 1 to 3.
- the slot-like recess 10 of the locking lever 9, like the sliding block 12, has oblique side walls 31 relative to the axis 11 of the locking lever 9.
- the force-transmitting side walls 31 are oblique to the axis of the actuating cylinder 2 or so too aligned to the axis of the push rod, so that there is a significant force component perpendicular to the axis of the actuating cylinder according to the laws of mechanics.
