Definitions
- the invention relates to a method and an arrangement for positioning trolleys for conveying, moving, positioning and holding of railroad cars.
- Conveyor systems are used on railroad shunting systems, in particular for pushing together railway wagons in the directional tracks. They have the task of compressing the wagons into a so-called dome-ready compound, which in this way simplifies train formation without the additional use of shunting locomotives.
- the conveyor systems have trolleys for this purpose, which move individually in each direction track or in sections staggered therein. They are driven by cable pulling means, the trolley usually being integrated in an endlessly circulating cable which is operated via a drive unit and mostly via hydraulic tensioning devices.
- the trolleys are equipped with conveyor arms, at the ends of which there are push rollers and which are brought into engagement with the wheel flanges of a wheel set in order to move a wagon to be moved.
- the conveyor arms are locked in a swiveled-out position, which brings them into engagement with a wheel set in the transport direction, while this lock is ineffective in the return direction of the conveyor truck or when it is rolled over by a carriage running in the transport direction.
- Such conveyor systems typically constructed in accordance with the prior art are regularly exposed to considerable mechanical stresses and therefore place high demands on a very robust construction. Accordingly, they are prone to failure.
- the reason for such wear-intensive use of the conveyor systems results on the one hand from loads on the spring-loaded locking of the conveyor arms during return movements below the wagons or during overhauls by the latter, the conveyor arms being regularly pushed aside against the spring force of the locking device supporting them.
- a high level of wear results from the previously unsatisfactory solutions for positioning the trolley with sufficient accuracy in relation to the locations of the wheel sets of the wagons to be conveyed. This a- It is also the prerequisite for an adapted mode of operation of controllable drives for conveyor systems and for the associated targeted control of pivoting movements of the conveyor arms.
- the procedure is usually simple to let the trolley run onto standing wagons or standing wagon groups without braking and to impress the conveyor speed of the trolley immediately after the impact has occurred.
- DE 198 55 930 describes a wagon conveyor device for shunting systems in which the play of the cable drive is prevented or minimized by a tow rope and a return rope with both Are connected sides of the trolley, and these two ropes are each separately to the motor winches arranged at the ends of the conveyor line. These motor winches can alternately run in towing or return mode. The non-driving motor winch builds up a braking force so that the rope that is not under tension is always kept taut.
- an insulated conductor is arranged in the interior of the ropes, which takes over the control of electrical devices on the trolley, "such an electrical device being, for example, a drive device for pivoting in or out conveyor arms. It is possible in this way that the conveyor arms only then in the working position if they are required for this, so that at least a wear-free return of the trolley is guaranteed.
- the impact of a standing wagon or a standing wagon group in the direction of transport is not minimized because the positions of the wheel sets which the conveyor arms are to be brought into engagement in a targeted manner cannot be determined.
- DE 41 01 078 describes a control device for operating conveyor systems which uses the known drive concept of asynchronous three-phase motors in connection with the control via frequency converters for driving the trolleys by using the speed data determined before entering the direction track target values for conveyor speeds are derived from the wagons or wagon groups to be conveyed.
- the method enables an energy-efficient and thus wear-optimized mode of operation, since the drive energy can be used in a very metered manner. It does not, however, minimize the main causes of the increased wear on conveyor systems, since solutions for axis-related positioning of the trolley are not shown.
- the invention has for its object to provide a method and an arrangement for a conveyor, whereby the position of the trolley in relation to the wheelsets of the railway wagons to be conveyed is clearly recognized both when the wagon is at a standstill and from a relative movement and the conveyor arms in one Transport as well as in a braking direction can only be swung out when an optimal conveying position is reached.
- a plurality of wheel set sensors are arranged on the trolley in such a way that the direction-dependent approach to a wheel set is ascertained, that a retrieval of the trolley on a wheel set or the retrieval of a wheel set on a trolley depends on the direction
- further wheel set sensors are arranged within an essentially symmetrical set-up of conveyor arms and brake arms in such a way that an optimal conveyor position is signaled, and that the conveyor arms can be swiveled in and out by a motor and the drive of the trolley via asynchronous three-phase motors in Connection is made with a frequency converter.
- the symmetrical arrangement of the conveyor arms and brake arms with at least one wheel set sensor located between them enables the wheel set of a wagon to be conveyed to be gripped almost slip-free and in this way to move the wagon in a targeted manner.
- the trolley can thus also be used as a holding device or positioning device, for example at loading or treatment points.
- the ability to clearly position the conveyor wagon in relation to the wheelsets of the wagons to be conveyed is an essential prerequisite for significantly reduced wear on the conveyor system during operation.
- a trolley can now be moved with the conveyor arms initially swung in, for example along a directional track, to a carriage located at an undetermined point. As soon as the trolley is under one of its wheel sets, it is recognized with the help of the wheel set sensors. The drive of the trolley is then stopped and the trolley is moved back if necessary by a certain amount. The trolley then starts again, but gently, and stops exactly at a point at which the wheel set sensor arranged between the conveyor arms and the brake arms emits a signal for the optimal conveyor position. Only then are the conveyor and brake arms swung out and come into engagement with the wheel set. The subsequent conveying movement starts again with a gentle start.
- wagons located along the direction track can also be deliberately omitted.
- Such a procedure can be very useful, for example, if conveying or pushing-back strokes have to be carried out on too many wagons that are on gaps and possibly heavy.
- this task can be carried out step by step without the risk of overloading.
- All movements of the trolley are driven by the asynchronous three-phase motor and controlled by the frequency converter.
- inductive sensors are used for the wheelset sensors, which generate a signal with high precision precisely when a wheelset is located directly above these inductive sensors while it is rolling over them.
- the signals from the wheelset sensors are routed via a trailing cable to a fixedly installed control system.
- the trailing cable is pulled up by a cable winch taken and leads from a drive station to the tram.
- This trailing cable is also used to transmit the control signals for the motor drives of the conveyor arms and to supply electrical energy for the operation of the sensors and the motor drive.
- Fig. 1 shows a schematic structure of a trolley according to the invention
- Fig. 2 positioned on a wheel set of a carriage to be conveyed
- Trolley and Fig. 3 shows a schematic structure of a conveyor system according to the invention.
- freely rotatable rollers 2 which are supported against the rail feet of running rails 3, are arranged on a frame-like trolley 1 at the ends of its longitudinal sides.
- the trolley 1 is located above these rollers 2 in a guide for movements along the travel rail 3.
- the trolley 1 is connected on both sides to a drive cable 4 at the front.
- the conveyor carriage 1 is provided with four conveyor arms 5 which are arranged to be movable.
- Push rollers 6 are located at the ends of the conveyor arms 5.
- the conveyor arms are also equipped with a motor drive. In a pivoted-out position of the conveyor arms 5 caused by the motor drive, they engage with their push rollers 6 on both sides of a left and a right wheel flange 7 of a wheel set 8. If the conveyor arms 5 are not pivoted out, they lie, as shown in FIG. 1 , for railway vehicles without a profile on the tram 1.
- wheel set sensors 9 Exactly in the middle between the pair of conveyor arms 5 arranged symmetrically to each other are two wheel set sensors 9 based on the inductive principle. These wheel set sensors 9 are constructed in such a way that a signal is generated by them when the wheel set 8, as can be seen in FIG. 2, is located exactly above the wheel set sensors 9 and in the middle between the conveyor arms 5.
- the trolley 1 also has further wheel set sensors 9, which are arranged in a double arrangement symmetrically to its longitudinal axis on both sides of the conveyor arms 5 and outside their effective range. These wheelset sensors 9 are also constructed and produced on the inductive principle. conditions a signal if they are passed directly under a wheel set 8.
- the drive cable 4 is designed as an endless circulating rope. It is moved by a drive unit 10 and runs via a hydraulic cable tensioning device 11. The drive cable is guided within the rails 3.
- a trailing cable 12 according to FIG. 3 is also brought up to the trolley 1.
- the trailing cable 12 is unrolled from a cable winch 13 and at the same time kept taut by it. If necessary, the cable winch 13 also automatically rewinds the trailing cable 12. Electrical energy is transmitted to the trolley 1 via the trailing cable 12.
- the transmission of the signals generated by the wheelset sensors 9 to a controller 14 and the transmission of control signals from the controller 14 to motorized actuators for the conveyor arms 5 are carried out set the wagon to be conveyed in motion. It is initially irrelevant at what distance the trolley 1 is currently to the wagon.
- the arrival at the to be conveyed car is detected based on signals "are generated by the on-the trolley Radsatzsensoren 9, as soon as they reach a position below a first set of wheels 8 of the car.
- the drive of the trolley 1 is accordingly stopped when the signal is sent by the designated wheel set sensors 9
- the trolley 1 and its associated extended reaction path is then first slowly moved back a certain distance, while the wheelset sensors 9 located on the opposite side of the trolley 1 immediately signal the approach to the optimal conveying position If at least one of the wheel set sensors 9 arranged in pairs in the middle of the conveyor arms 5 emits a signal, the trolley is stopped again. Then the four conveyor arms 5 are swung out and brought into positive contact on both sides with the wheel flanges 7 of the wheel set 8. The trolley 1 then starts up smoothly and executes the conveying job until a predetermined position is reached.
