Abstract

The point system has rails whose ends (18) are curved away from each other. The rails are linked by connecting rods (7), forming a flexible track section which can be curved to connect with a branch in the track. This is carried out using a system of levers (12) below a block (6) on which the track is mounted and which is connected by a rod (9) to an eccentric wheel (3) and lever (5) which move the track section.

Description

The invention relates to a branch switch in which the two ordinary, with Connecting rods coupled to rails form a bendable rail branch and serve, see (Lexikon der Eisenbahn - 8,... ed. edition Stuttgart: Motorbuch Verl., 1990. p. 870) "Switch: superstructure construction, the rail testify from one track to another without stopping the journey light. W. consists of one or more tongue devices, one or several centerpieces. . . and other switch material ".

From the A. Z: P 20 51 882.5-25, is known "tongue switch with two tongues pair from track sections of the main and the branch track". According to claim 1, "characterized in that the free ends ( 8 , 9 , 10 , 11 ) of the tongues ( 2 , 3 , 4 and 5 ) each have a bevel ( 26 , 27 , 28 ,) 29 )..., And that the closure elements are wedges ( 20 , 21 ), each of which can be inserted positively into the recesses formed by the bevels between the free ends of the tongues and the connecting rails ".

But after the course of the tongue rails ( 3 , 4 ) in Fig. 1 they have to cross and this includes the heart with the wheel control arms.

From DE 195 13 869 A1. "Branch railroad track switch." According to claim 1, "characterized by the following features: d) when adjusting the switch tongue ( 1 ), the two tongue legs ( 1 a, 1 b) on sleeper plates ( 11 ) can be moved between two support brackets ( 10 ) serving as end stops"" , and from patent claim 4, "characterized in that spacers ( 15 ) are provided between the two tongue legs ( 1 a, 1 b)". But a construction that is assembled from the tongue legs ( 1 a, 1 b) is simply immovable.

Therefore, the conventional designs cannot solve the problem.

The invention is based on the object, one for the high speed Development, rail transport to develop suitable switches that in comparison no special switch material is required for conventional constructions.

As a special feature of the branch switch, they are gawalz in a special way end of the rail according to, (IPC Hkl: E 01B 11/24 Akz. 100 42 366. 3-25. Ant. 30.08.2000. Ref. Double rail joint: legible connection of two successive rails, for railway superstructure).

Here, two uniform, with rolled butt ends, rails are movably coupled together using numerous connecting rods and form a bendable rail branch, on each branch rail foot, in order to achieve stability, numerous base plates are fastened, according to the number of support brackets on the rail foot, in the support frame area, two Rollers attached laterally. Trestle actually, a vertically movable beam that is located across the branch. To set this in motion, see (Lexicon p. 872) "Turnout mechanism: part of the changeover device mounted on the turnout, a remote-controlled turnout". On the (p. 873) see illustration "electrical switch drive", with the difference that instead of the gear acting on the "actuating rod 2", a drive shaft is coupled to the "worm wheel 7 ". The drive shaft is mounted parallel to the main track, on which numerous legs and eccentric disks are mounted, which serve; the eccentricity disc by means of a lever linkage lifts the trestle with the branch switch to the appropriate height, then the branch switch is removed from the leg by means of a pull rod, from trunk to branch track; or vice versa, adjusted. The leg circumscribes an arc approximately over 180 °. It is intended that the adjustment of the branch switch begins when the branch is lifted.

Lifting the trestle with the branch can be done hydraulically become.

Cones or are on the sleepers to match the base plates Edge ribs to prevent side shift, built in.

The branch switch is attached to the main track (rooted) and the free branch end of the branch top is made as needed by means of rails pushing and moving support, with the trunk or branch track put together.

Position of the connecting rod

The electric turnout drive ( 1 ) is identical to the see (Lexicon p. 873, Fig. 1) with the difference that the "worm wheel ( 7 )" is coupled to the turnout drive shaft ( 2 ).

The turnout drive shaft ( 2 ) made of seamlessly drawn steel tube or section of a railroad track with multiple bearings ( 4 ), according to the number of legs ( 5 ) and the same number of eccentricity devices ( 3 ).

The eccentricity devices ( 3 ), see on the ( Fig. 3), when turning the shaft ( 2 ), the eccentric disc ( 3 ) acts on the role of the lifting device rod ( 9 ) and the lever ( 12 ) lifts the support bracket ( 6 ) with the switch branch.

The legs ( 5 ) Durable bolts, on the turnout top it is half as long as the adjustment range of the branch turnout. the legs ( 5 ) closer to the branch turnout root are correspondingly shorter. When the shaft ( 2 ) rotates, each leg ( 5 ) circumscribes an arc approximately over 180 °, this is intended so that the adjustment of the switch begins when the switch is lifted and is placed on the bedding after which the branch is Has reached position.

The switch support frame ( 6 ) made of permanent pipe or railway rail section is preferably arched according to the radius from the switch branch root and is used to pick up the switch branch before the adjustment and after the adjustment to lower the bedding, stand at a distance under the switch.

The rail connecting rod ( 7 ) articulated rod ( 7 ) attached to both rails, the position of the rod ( 7 ) see on ( Fig. 6) is calculated according to the triangle ( 19 ) and depends on, see (Lexicon p. 710) " Track extension: enlargement of the basic dimension of the track width of a track. Prescribed track extension of the DR for normal track; from 5 to 15 mm ", in the triangle ( 19 ) the cathetus (b) is constant 1435 mm, the hypotenuse (c), depending on the curvature ( 1435 + 5, + 10 or + 15 mm) and the cathet a ² = c ² - b ² .

The pull or push rod ( 8 ) made of profiled steel or tubular steel, in the leg ( 5 ) it has a curvature, which allows the leg ( 5 ) to drop below the horizontal and serves to branch from the leg ( 5 ) to the switch Transfer force.

The Hebevorrichtungastange (9) made of profile steel or steel tube (FIG. 3) in the Exzentrizitätsscheibe (3), the rod has (9) are provided with disk (3) kon lactating roller to the other end of the rod (9) two or three Lever ( 12 ) is articulated.

The lifting device can also be implemented hydraulically.

The branch support roller ( 10 ) is attached to the rail foot and roll on the support bracket ( 6 ) when switching the switch.

The trestle slideway ( 11 ) made of two matching tubes can be replaced by hydraulic cylinders.

The rail joint end ( 13 ) belongs to the immovable main or branch track rails.

The rail joint end ( 14 ) belongs to the branch turnout.

The support ( 15 ) is at each fixed rail joint end ( 13 ) and does the joint end ( 14 ) press against the joint end ( 13 ).

The base plate ( 16 ) serves to secure the roots of the branch switch.

The base plate ( 17 ) is the last of the main track.

The dividing line ( 18 ) of the double joint between the main track and the branch switch.

In order to achieve stability, branch rails are on each branch numerous base plates attached (not labeled).

In order to avoid side shifting, pins are on the sleepers or built-in ribs to match the base plates.
