Description

BACKGROUND OF THE INVENTION The present invention relates to a device for locomotion without a locomotive. Such structures are generally used in industrial sites where locomotives are not always available for moving railcars - wagons. The device according to the invention can be advantageously used in wagon staging points, loading yards, e.g. track grading systems for coal grading workshops and the like.

Known structures for the same purpose as the invention are generally connected to a rope system, and the ropes are connected to the drive machine by rope drums and a gear. Electric motors are usually used as propulsion engines.

One of the typical types of rolling stock known in the art is the arrangement whereby the structure is operatively moved on an auxiliary track built between a pair of railway tracks. Such a structure has a very high tendency to derail. These structures easily jump out of their paths under point loads. The derailment of the structure, in addition to causing a breakdown, also poses a risk of accident. A further disadvantage of such a solution is that the construction of the auxiliary track requires significant costs. In the case of such known solutions, the auxiliary track will generally have to be constructed in the same manner as the main track, because the whole load resulting from the operation of the structure will be absorbed by the auxiliary track. The cost of such known solutions is also exacerbated by the fact that the structure has to provide a separate garage so as not to obstruct the movement of railway locomotives. This garage is actually reinforced concrete

-1180.308 shafts located between main rails. This garage can be used to provide the azer structure * on the lowered auxiliary track between the main rails. In said garage, the actuator is located outside the space gauge.

The drawbacks of the laminate solution outlined above can be largely eliminated by a structure that does not have a separate auxiliary track, because the rollers of the structure fit onto the main track. A wide variety of variants have become known in the family of roller-supported roller structures. In particular, the levers carrying the rollers are motors of motion. with regard to the position of the rollers and the position of the rollers. A typical example of such a system is disclosed in Register 317,293. Austrian patent specification. In this solution, in addition to the roller supports, there are also support rollers which rotate about the vertical axis of the sihgerinch.

In the case of solutions with a system of runners, there is generally no risk of derailment, since roller rests on the base of the rail are prevented from sliding upwards by a design such as a roller having a horizontal groove between the runners and the ridge. A major disadvantage of the structural solution just outlined is that it can only be used with welded rails, and it can only be used with one type of fastener. In addition, in general, quite stringent standards need to be met for the path in which this structure is to be used. Usually not on the tracks where the need for non-locomotive wagon movement arises. a path is available which is satisfactory for the application of the latter known structure. For this reason, a special track network should be constructed to allow the use of the wagon drive mechanism. However, such track construction requires very high costs, so they use a simpler wagon handling mechanism rather than rebuilding the track.

The device according to the invention completely eliminates the disadvantages of known similar solutions. The object of the device according to the invention was to allow the simple mechanical construction of the device to be used in a system of rails of any size, with rail fastening methods, so that the risk of derailment and the likelihood of a malfunction were minimized.

The device according to the invention accomplishes the foregoing purpose largely by using the main rails for running in operation, since the rollers on these rails are running. The structure requires an auxiliary track, but this auxiliary palace is used temporarily and unloaded by parts. Therefore, only a part of the weight of the structure may be teffed, and this load will only act for a short time. In fact, in the structure according to the invention, the reaction of forces during the movement of the rail vehicle is traced back to the rails of the main track precisely because of the structure of the structure. Under these circumstances, the auxiliary track can be made quite simple, for example from a rolled semi-finished product (nail). The structure according to the invention does not require any special requirements for the main track, neither in terms of the rigidity of the rails, nor in terms of their size or rail fastening methods.

In the device according to the invention, a lever is used at each of the four corners of a carriage body. Is one pair of rollers mounted at one end of each swing arm? one of the pairs of rollers leaning on the railway track while moving the vehicle and the other roller leaning on the wheel rim of the moving vehicle to move the rail vehicle. The swing arms are connected to the swing arms via hinges and intermediate members. The clutch levers press on the wheels of the sine shaft to rotate the lever arm against the spring by its own movement, until one of the wheels of the sine shaft gets between opposite pairs of rollers connected to the same rail. There are four support rollers mounted on the car body, which can be connected to the auxiliary track when the swing arms, together with their end-mounted pairs of rollers, turn between the main rails so that the running wheels do not rest on the main rails.

Deflection rollers may be mounted on the trolley body of the device of the invention, cooperating, if necessary, with deflectors disposed along the rails, to allow the tilting of the tilt rollers between rails, even if the blade shafts are to be moved to a different position than operating.

In a preferred embodiment of the device according to the invention, the lever acting as a lever for moving the swinging arm is inserted between the swinging arm and the carriage so that it is in each position closest to the latter, for easy connection with the wedge of its moving vehicle. sine side.

The structure according to the invention forms a rather rigid mechanical system while moving the rail vehicle. This stiffness can be partially unlocked if the motor for moving the structure is a hydraulic motor. Namely, the hydraulic motor is a resilient element for the entire propulsion system, and thus the movement of the sinusoidal gear is ultimately lost from the stiffness caused by the structure according to the invention.

Is the structure of the invention? that the body of the car, at its four corners, has a swivel arm which is pivotally mounted about vertical axes having a running roller mounted on one leg, supported on the spindle while moving the sinew vehicle, and a sliding roller which supports the sinew wheel track arm. the other arm is connected to a spring for moving the swinging arm, and each swing arm has a switching arm connecting the car body to the swing arm by means of intermediate members and joints, and a support roller supported on an auxiliary track.

The invention will be described in more detail and in detail with reference to the exemplary embodiment illustrated in the accompanying drawings.

In the drawing, .....

Figure 1 is a front view of an exemplary structure;

Figure 2 is a top view corresponding to Figure 1.

The body of the structure forms a body 6 which is mechanically rigid. At each of the four corners of the body 6 there is a pivot arm 3 pivotally mounted about vertical axes. A pair of rollers is provided at the ends of the outer arms of the swivel arms. Among the pairs of rollers, the outer running rollers 1 are provided

-3180.308 relying on the main track's ginkgoons in operating position. In addition to the piston rollers 1, two sliding rollers 2 are mounted on the inside of the carriage body 4 6, or are these sliding rollers supported by the wheel flange of the rail vehicle when moving the rail vehicle? It does.

The arms of the swinging arms 3 facing the inside of the body 6 are engaged with the springs 4, which ensure that the swinging arms 3 are brought into operating position and kept in this position.

Each mechanism forming the link between the pivoting arm 3 and the body 6 has a pivoting arm 5 for engaging the pivoting arm 3 towards the center of the body 6 when it strikes the wheel of the car to be moved.

The arm of the swinging arm 3 connected to the spring 4 is connected to a lifting track which serves to slightly raise the swinging arm 3 and, with it, the running curve 1 and the sliding roller 2 as the swinging arm 3 turns. This lift is necessary so that when the spring 4 causes the rocker arm 5 to swing, the running roller 1 will not strike the sync crown.

Support rollers 7 are mounted on the sow body 6, which in temporary cases support the auxiliary track 9. As can be seen from the exemplary embodiment illustrated in the drawing, the auxiliary track 9 consists of a simple and inexpensive construction of angular steels, which in this case are fastened to a light sole.

In the exemplary embodiment shown in the drawing, deflection rollers 8 are connected to the lower part of the pivoting arm 3 so that these deflection rollers 8 can engage with guides which may be integrated along the main rails.

The device according to the invention is used or operated as follows.

The structure is connected to a rope system not shown in the drawing, consisting of endless rope branches guided between the tracks. The ropes are connected to the drive machine by rope drums and a gear, which is preferably a hydraulic motor for the operation of the device according to the invention. Figure 2 shows one of the ropes connected to the carriage '6. Assume that the device, as interpreted in Figure 2, is moved upwards, half of a hypothetical and intended railway wagon. In Fig. 2, the upper rope branch connected to the car body 6 transmits traction to the structure, causing the structure according to the invention to move. During this movement, the running rollers 1 roll on the rails of the main track. The support rollers 7 are not in contact with the auxiliary track 9 and are located above it. .

When the device rolls under the train to be moved, the linking arms 5 of the tilt arms 3 shown in FIG. 2 strike the wheels of the rail sows. As a result of the traction force exerted by the aforementioned rope, the wheels of the railway carriage rotate the coupling arms 5 towards the middle of the coach body, and by virtue of the mediating role of the coupling arms 5, the pivoting arms 3 pivot. As the swing arms 3 turn, the arms of the swing arms "engaging" the springs 4 run into forced paths which engage the swing arms 3; slightly elevated. The running rollers 1 at the ends of the swing arms 3 are thus displaced laterally "and slightly elevated" from the rails below. Let the support rollers 7 intervene in the passage 9

They sit on the pitch of -4180.308. In this situation, when the upper support rollers 7 of the structure run on the auxiliary track 9 and the lower running wheels 1 roll on the rails of the main track, the structure proceeds until the intended pulley wheel is approached by the lower running wheels 1 and 2 respectively. two. The springs 4 then move outwardly on the upper tilt arms 3 of abra 2 behind the outgoing wheels. During this movement, the running rollers 1 do not strike the sync crowns of the main track because, as previously mentioned, they were slightly lifted by a forced track during the inflection of the swing arms 3. In the final phase of pivoting of the pivot arms 3, the running rollers 1 fit into the rails of the main track and at the same time the support rollers 7 in the upper part of Fig. 2 rise from the auxiliary track 9.

In addition to the outlined position of the device according to the invention, each wheel of the rail intended to be moved is surrounded by the running rollers 1 and 2 sliding rollers 2 belonging to the same rail. THE

As illustrated in Figure 2, when the upper rope branch is extended, the lower sliding rollers 2 are supported by the trails of the trolley arms in front of them and are driven by the force exerted by them.

When the wheeled vehicle, which is moved by the device according to the invention, reaches the unlocking position, the pre-installed guiding plates are supported by the guide rollers 8 supporting them to pivot the swing arms 3 and the running rollers 1 and 2 from beneath the sinewy grass. It should be noted that other structures are also suitable for providing a release position. Thus, it is not necessary to use the deflection rollers 8 and the deflection plates which control them.

After the last switch-off point, the sinking section of the auxiliary track 9 allows, of course, with the four tilt arms 3 in the inverted position, to lower the structure according to the invention to the crossbeams, outside the space profile.

The structure and operation of the exemplary structure show that the invention is extremely simple in mechanical design and can be made by users in their own workshop. The structure according to the invention does not require any rebuilding of the track system, since it can be used with any size of rails, any type of rail connection and rail reinforcement elements. The likelihood of derailment of the device according to the invention is almost zero. From the economic point of view, the present invention is extremely advantageous. The economic advantage is not diminished by the fact that a beginner's track is needed, given that the auxiliary track required by the structure is simple and cheap to build.
