Overhead track switch

The invention relates to a suspension track switch for a main and at least one secondary rail with the main and secondary rails assigned transversely displaceable switch rails.

Up to now, the points have been shifted by electric motors, hydraulic or pneumatic cylinders and placed in the respective End positions held without additional safeguards. In the case of leaking cylinders or lines or not working properly Brakes on the electric motors caused vehicle vibrations to move the switch and thus to malfunctions. the known displacement devices are also very expensive and dependent on an energy supply.

The object of the invention is to create a simpler and safer overhead track switch. This is what makes this job solved that a bolt is arranged on the switch rails

is the one that is led to both sides of the switch Tension members connected and can be moved into the open position when pulling on a tension member against spring force which brings him the spring force in its end positions after lifting the tensile force in the locking position, in the he with his bolt surfaces behind fixed bolt latches engages.

By actuating the tension member, the switch is pulled into the desired end position after unlocking and there again held securely by the bolt on the bolt latch until the switch is pulled into the other end position and there is held again.

According to further features of the invention, the latch latches are preferably attached to a frame in which the switch rails are arranged to be transversely displaceable. The latch is in the direction of movement of the turnout rails Lying, centrally mounted swivel lever that can be moved in a vertical plane, which is on both sides its pivot bearing has hook-shaped projections, on which the locking surfaces are arranged, the tension member is outside the pivot axis on the locking bar, preferably attached in its transverse center plane. The locking surfaces are present on both sides of the central axis of the locking bar, vertical surfaces for adjusting the turnout. The bolt is preferably made of sheet metal or a flat iron manufactured and therefore very inexpensive. When pulling sideways, the bolt tilts or swivels around a bolt, whereby the locking surface opposite to the pulling direction slides along the fixed latch and then the Lateral shift of the switch allows. Before the

the locking surface facing the direction of pull engages behind the locking latch, the bolt is locked by one on the locking latch pivoted along the run-up surface.

In order to prevent unintentional tilting or pivoting of the bolt, the bolt has further features of the invention on both sides of its pivot bearing pressure surfaces for springs supported on a bolt carrier. The springs are preferably coil springs and an in the bolt or the bolt carrier attached pins out. When the switch is unlocked, the direction of pull is determined facing spring stretched. It relaxes again as soon as the switch has reached the other end position and the bolt surface is locked behind the bolt latch.

The tension members are preferably ropes and guided horizontally across the width of the frame and from the stationary horizontal guide then deflected downwards. At the hanging ends of the tension members can Handles be attached. By pulling down the handle, the latch is first unlocked and then the switch moved sideways up to stops that are adjustable screws.

An embodiment of the invention is shown in the drawings and explained below.

Pig. 4 shows the latch on a larger scale, FIG. 5 shows a plan view of FIG. 4.

The stationary main rails 1 and secondary rails 2 end in a frame 3 'which is trapezoidal in plan view consists of side members Yes and cross members 3b. To the Cross members 3b are support ledges 4 by means of consoles 3c for the transversely displaceable switch 5 attached. The turnout cross members 8 form a frame with a straight main rail 6 and a curved secondary rail 7. To the Switch cross members 8 are attached to bearing strips 8a which, when the switch 5 is moved transversely, on the support strips 4 slide along the frame 3. A cross member 9 is attached between the longitudinal members 3a of the frame 3, are arranged on the bolt latches 10.

On the main rail 6, a bolt carrier 11 is attached with bearing eyes 12 for a bolt 13 on which a Latch 14 is stored. The bolt is a centrally mounted pivot lever in the direction of displacement of the switch, which is movable in a vertical plane. The bolt 14 is above the bolt 13 with a bore provided, in which a pulling member 16, z. B. a rope with a clamping lug 17 is attached. The tension member 16 passes through tubes 18 which are attached to the longitudinal beams 3a and which are at the ends at 18a turned down. At the two ends of the tension member 16, a handle 19 is attached, with which Help the switch is adjusted and unlocked at the same time.

The mode of operation of the device shown is explained with reference to FIG. 4:

309843/0177

DFT 76? - KoAa - 5 - April 12, 1972

The bolt 14 and thus the switch are in the illustration in the left end position. The latch 14 engages with its left locking surface 14a behind the left one Latch 10, which consists of a flat iron and is attached to the carrier 9 in such a way that the 'soft rails, in the illustrated end position, the desired position, for. B. Drive straight ahead through the main rail 6. The latch 14- is normally held in a position in which both downwardly directed projections 21 provided with the locking surfaces 14a are at the same height, However, the ends of the projections 21 are still deeper than the upper edges of the latch latches 10 are located. To keep the bolt 14 in the normal position, are on both sides of the bolt 13 arranged helical springs 10, which are guided on pins 22 attached to the bolt 14 and on the one hand abut against pressure surfaces 14b of bolt 14 and, on the other hand, against bolt carrier 11.

If the pulling means 16 is pulled to the right (FIG. 4) to adjust the switch 5, the bolt 14 pivots up around the bolt 13 on the left, whereby the hook-shaped projection 21 located there with the bolt surface 14a 'is released from the bolt latch 10. As soon as the pin 22 leading to the spring 20 on the right strikes the bolt carrier , the adjustment of the switch begins when the pulling means 16 is pulled further. Shortly before reaching the right end position, the contact surface 14c located on the right of the bolt 14 runs onto the bolt latch 10 located there. The bolt 14 is raised so far on the right that the right hook-shaped projection 21 with the bolt surface 14a engages behind the latch 16. When the pulling action on the pulling means 16 is stopped, the bolt 14 resumes its normal position in which it moves the turnout

Rails now in the other end position, e.g. B. Passage in the branching rail. When activating the switch by pulling the traction device in the opposite direction Direction is the adjustment of the switch to the left.

For precise adjustment of the switch end position, adjustable stops 23 are in the form of the longitudinal members 3a arranged by screws on which the turnout crossbeams 8 are in the respective end position. Appropriate adjustment devices can also be attached to the latches to be appropriate. The illustrated embodiment is a manually adjustable switch. Of course, the traction means can also be carried out with the aid of electrical, hydraulic or pneumatic devices be operated.
