DE360936C - Line blocking device, especially for suspended electric railways - Google Patents

Description

In electrified monorail systems, it is known to block the lines for the purpose that, when a car fails and stops and the next car to it Car comes, this is also stopped. In construction, where this through Blocking individual route parts is achieved, there is the disadvantage that the blocking devices in distances that are too great

10 'must be provided so that the carriages are only at the same great distance from each other can follow.

.. There are also route blocking devices known, each with a blockage is provided on each car, especially those where each car is still pulls a tow truck in front of or behind it so that the tow truck pulls the blocking device contains. The latter devices have the advantage that the car is one piece can follow one another as closely as you like * and on the other hand the following carriage cannot bumps into the disturbed, stationary main car, but in the blocking car that is a little further away and has a much smaller mass and expediently runs into it in a resilient manner.

The present invention now describes such an arrangement of the last-mentioned route blocking devices, which the stated goals in the simplest and most reliable way Way achieved.

Details are also important for the invention the design, such as in particular connecting links between the main car and block wagons a flexibility ils run-out path for the following wagon offer, also the design of these links as a rope in conjunction with tight brakes of the block wagons and similar points.

The drawing illustrates two embodiments of the invention on an electric monorail with the log car towed by the trolley, namely:

Version with main carriage and block carriage coupled by articulated levers, Fig. 2 simplified side view of an embodiment with coupled by cables Main car and block car. In the first embodiment, the trolleys carry ι ^a , ι ^b , ι ^e articulated levers 2, which are combined in joints 3 with further articulated levers 4 from the block carriage 5. Load weights 6 seek the levers 2, 4 to approach the extended position, but are prevented from doing so by a chain 7 or a similar stop device, so that the levers always have to assume a roof-shaped position. An approach curve 8 is attached to each block carriage 5, and each trolley has its pantograph 9 in a hinge 10 so that it can be folded down in such a way that a counter arm 11 of the pantograph is folded down when it runs onto its roller 12 on the approach curve of the preceding trolley, and thereby becomes that is, the following carriage is automatically stopped by the required discharge path being available by tilting the articulated levers 2, 4. The drawing illustrates a position in which two carriages i ^b , i ^c on a leading carriage. i ^{a had} accumulated and this car τ ^α has started to run again and is just about to enable the next car i ^& to continue its journey. In the second embodiment (Fig. 2), the trolleys are designed similarly, only the current collectors 9 cannot be lifted, but there are pendulum levers 13 with rollers 14 to run onto the Auflaufkucven 8 of the block car, so that by switches that pendulum levers are controlled, the power of the car concerned is switched off. The connecting links between the trolley and the block wagon consist of ropes 14, which if necessary are supported by pendulum-loaded support rollers 15 in intermediate points, and the block wagons 5 each have a shoe brake 17 pressed against the rail by means of weight 16, which is activated by the connecting ropes 14 when the tension is tight of the rope is lifted, on the other hand it is indented when the rope becomes slack. The effect here is that when a carriage runs into the leading block carriage, the trolley is de-energized and its discharge ^{path is shortened by the braking effect 1 of} the block carriage; This braking effect also prevents the block car from running into the main car on a slope. In both embodiments, as can be seen, when driving on points the In contrast to all other facilities, the conductor rail cannot be switched. Driving on tippers or lifting platforms is also easily possible by using the Car can be shut down automatically by means of its switch-off parts. For this purpose, in the first embodiment, a pick-up of the Block wagons on the main wagons in order to shorten the required overall length of the tipper be provided by placing a roller on the side of the joint 3 of the joint lever, which leads up to an inclined plane in the tipper, thereby lifting the articulated lever and pulls the block carriage (as shown in Fig. 1 on the right) towards the main carriage. before the dump truck or the conveyor platform can cause the wagons to stand still from this by the last piece of the Fahrichiene only when the receptive position of the Tipper or the conveyor platform is supplied with power from this. Patent A ν claims: ι. Route blocking device, in particular for electric monorail systems, characterized in that at some distance in front of or behind the transport trolley an associated block car with an inclined plane runs up whose inclined plane, when two cars approach each other, a lever on the other car runs up and turns shifts that thereby a circuit breaker or in particular the pantograph is knocked down .. 2. Device according to claim 1, there- - characterized in that as a link between the main car and the block car a toggle-like linkage is used, whereby the folding of the toggle rod when the Blocfawagens approaches to the main carriage is counteracted by weights. 3. Apparatus according to claim 2, characterized in that the connecting member between Haoptwagen and block wagon in a rope "that with a brake of the Blocbwagens like that What is coupled is that it lets this brake fall when you are sheep the block car approaching the Main carriage prevented without the influence of a subsequent carriage. 1 sheet of drawings.
