Description

The invention relates to a maintenance device for bogies of railway cars or parts thereof.

According to [1], DE29503603U1 , Overhaul or replacement of the bogies and the drive motors and other components are often required in maintenance, overhaul and repair of rail vehicles. The bogie in need of overhaul is dismantled from the rail vehicle at a workshop and, after being overhauled, re-mounted on the rail vehicle. To dismantle the bogie, the rail vehicle is usually jacked up by means of a lifting system which engages the vehicle frame. A separate bogie lift within the vehicle lift system is used to raise and lower the respective bogie.

Another device for exchanging bogies on rail vehicles is from [2], DE4405279C1 , known. In this device, a truck moves in a tunnel under a bogie to be replaced. As a result, a spindle lifting table provided on the pallet truck is raised to support a track bridge, which is subsequently unlocked and lowered with the bogie released from the rail vehicle. With the truck, the bogie is driven via tracks and one or more turntables to a delivery point where the bogie is removed from the track bridge.

From [3], WO9008095A1 , An apparatus for exchanging bogies on rail vehicles is known, which has a mobile base frame, two height-adjustable lifting frame and a platform for receiving the bogie to be replaced.

The FR 2432989A1 discloses a maintenance device for a rail vehicle with two maintenance columns, each comprising at least a first lifting device and a gripping device by means of which the rail vehicle can be raised.

The present invention is therefore based on the object to provide an improved maintenance device for bogies.

From [4], CN202245961U , a device is known which comprises two lifting devices and two rotating devices by means of which a bogie can be raised and rotated. This device thus makes it possible to bring a bogie by lifting and turning in a position in which the maintenance personnel can access the bogie to perform repairs.

Note, however, that disassembly and replacement of individual parts of the elevated bogie with conventional tools, such as wrenches and pliers, are not easy to accomplish. In addition, individual parts of the bogie due to the use of spring elements, in particular of primary fields, under high mechanical stress, so that the parts can not be detached from each other without further measures and may. Often, the primary springs are under a preload, so that an axle bearing and a wishbone, as for example in [5], DE4010824A1 , are described, can only be solved and allowed if the bias of the primary springs is compensated first. This is not possible with the device shown in [4], so that only a part of the maintenance work can be carried out on these devices and further maintenance work has to be carried out elsewhere.

It should also be noted that when releasing a first axle bearing of a wheelset and the relaxation of only one primary spring tension can occur in bogies, which can lead to damage to individual parts of the device and to a threat to the maintenance personnel in the execution of further work.

In particular, a device for the maintenance and manipulation of bogies is to create, with all essential maintenance can be performed easily and safely, so that can be dispensed with the use of other tool devices.

In particular, the wheelsets, the wheelset and the wishbone to be easily solved by the bogie and replaced without security risks and damage to individual parts of the device can occur.

The maintenance device should be universally applicable and usable for the maintenance of different bogies. Furthermore, the maintenance should be carried out with little staff, preferably only a single person comfortably and without security risks.

The maintenance work should be carried out by means of the maintenance device so that when solving individual parts of the device no disturbing forces remain within the bogie.

This object is achieved with a maintenance device for bogies, which has the features specified in claim 1. Advantageous embodiments of the invention are specified in further claims.

The maintenance device, which serves for the manipulation and maintenance of bogies, comprises two maintenance columns, each comprising at least one lifting device and a gripping device by means of which the bogie is raised and preferably rotatable.

According to the invention, each of the maintenance columns on opposite sides on a first and a second pivotable tool arm, which is one of the tray of the Bogie serving support member and a processing of the bogie serving arm tool comprises.

The maintenance device according to the invention makes it possible to service bogies which are fed on rails. Other transport devices for the bogies are not required. The maintenance device according to the invention even makes it possible to hold or even lift a carriage from which a bogie is released. Preferably, the maintenance columns are slidable along the rails, so that from a first position, a railroad car raised and the bogie can be solved and at a second position, the dissolved bogie can be manipulated and maintained. Conversely, the maintenance device can be used to reconnect the detached bogie to the railway carriage.

By means of the gripping devices, a bogie detached from a railway carriage, which has been retracted on rails between the two maintenance columns, detected, raised, possibly rotated, processed and placed in the sequence on the tool arms to perform work that would normally require the use of larger forces and require further tool devices. The bogie is e.g. With or without wheelsets raised to the height of the tool arms, which are then rotated against the bogie. For example, the tool arms are rotated against the bogie so that the support elements of the tool arms are each arranged below a journal bearing of the bogie. As a result, the bogie is driven by the gripping devices down until one of the elements of the journal bearing rests on an associated support member.

The maintenance device can the bogie by means of various devices, the gripping devices and the Tool arms, capture and hold in different positions. By means of the gripping devices, the chassis of the bogie can be detected on the sides approximately in the middle. By means of the tool arms, the bogie can be advantageously detected in the storage devices of the two sets of wheels. The bogie can therefore be manipulated and held so that the device parts to be processed are exposed or can be edited with the tools of the tool arms. In this case, different maintenance operations can be carried out in which the tools of the tool arms are used or not.

By means of the maintenance device according to the invention, therefore, virtually all maintenance work can be carried out in a simple manner. In particular, maintenance work, in which a primary spring, a journal bearing or a wishbone are to be exchanged, are carried out particularly easily without the addition of further tools. For carrying out special work, it is therefore not necessary to set down the bogie again to be able to act on the bogie with separate tools.

After discontinuation of the bogie on the tool arms, the bogie can be advantageously operated by means of the tools of the tool arms.

The tool arms can advantageously carry one or more possibly also very heavy arm tools, by means of which can be acted upon by high force on the relevant device parts of the bogie.

Preferably, the arm tools are designed as presses, which allow the primary springs of the bogie to compress until the bias of the primary springs no longer from device parts of the bogie, but by the Tools of the tool arms is caught. The liberated from the bias device parts of the bogie can be solved in the sequence with simple measures, without special effort and without security risks. After releasing the device parts, by which the primary springs were biased, the energy stored in the primary springs is thus not released. The primary springs remain taut until the arm tools are slowly released, so that the primary springs can now be replaced. Just as relaxed primary springs can be biased again and provided for maintaining the bias device parts are mounted again.

The operations of tensioning and relaxing all the primary springs can be carried out synchronously so that the forces exerted by the primary springs are evenly compensated within the bogie and forces acting asymmetrically on device parts of the bogie are avoided.

In order for the arm tools to be operated synchronously, they are provided with tool drives, e.g. hydraulically, pneumatically or electrically driven actuators provided, which are preferably, wired or wireless, connectable to a control device, so that the tool drives can be controlled individually or synchronously. All primary springs of the bogie can therefore be synchronously tensioned and relaxed, so that all the corresponding device parts are moved synchronously and unilateral loads thereof are avoided.

The two maintenance columns are mounted on a platform which lies in a plane aligned parallel to the longitudinal axis and to a transverse axis of the maintenance device, in such a way that the gripping devices are parallel to the transverse axis are aligned with each other and can access from two sides to a bogie, which was retracted on rails between the maintenance columns. The rails are preferably arranged equidistant from the service columns on the platform and preferably run parallel to the longitudinal axis of the maintenance device. This symmetrical configuration allows a simple construction of the maintenance device and easy access to the retracted bogie by appropriate control and / or manipulation of the gripping devices and the tool arms. An asymmetric structure is possible, but associated with a greater effort.

The gripping devices are preferably provided with a telescopic support, which allows to drive the gripping tools against the bogie. Preferably, the telescopic support comprises two or more tubular telescopic elements, which are slidable into each other and hold a holding element for the gripping tools preferably in the middle. The holding element consists for example of one or more plates or rods along which the gripper tools are displaceable parallel to the longitudinal direction of the maintenance device.

The telescopic elements can be moved manually against each other. Alternatively, the telescopic support can also be associated with a preferably controllable drive device, by means of which at least one of the telescopic elements is axially displaceable. The gripping tools can be manually or automatically actuated.

The gripping devices are preferably held in guide rails and moved by means of a drive device perpendicular to the platform. For example, a spindle drive is provided, by means of which a spindle is rotated, along which associated gripping device is movable up and down. Preferably, the gripping devices are additionally rotatable about an axis of rotation extending parallel to the transverse axis. For example, the gripping devices are rotatably supported by a bearing block having a threaded member which is traversed by the spindle. Upon rotation of the spindle, the bearing block is moved vertically. In the bearing block, a preferably parallel to the telescope holder aligned and connected to this device parts can be rotatably mounted. If the bearing block is provided with a drive device, then the device shaft and the associated gripping device can be rotated automatically. Preferably, an optionally automatically actuated blocking device is provided by means of which the gripping device can be fixed and secured in a rotary position. For example, the device shaft or the telescopic device is provided with a toothed wheel into which a locking lever provided with at least one toothed element can engage. Once the locking lever is raised, the gripping device can be rotated.

The maintenance columns are preferably connected on both sides, preferably via a jib, each with a wrist joint, by means of which the associated tool arm is held rotatable about a rotation axis running perpendicular to the platform. The tool arms of the two maintenance columns can thus be rotated against an intermediate bogie and coupled with this.

The tool arms preferably comprise a telescopic support, by means of which the support element and the processing of the bogie serving arm tool against the bogie are extendable. The approximately radially aligned to the associated service pillar tool arms can therefore be rotated within a designated range and extended radially.

The gripping devices and the tool arms can be easily adapted to a bogie so that it can be easily and safely detected. By means of the maintenance devices, therefore, any type of bogies can be serviced.

The arm tools provided on the tool arms are preferably designed as clamps or presses, so that spring elements, in particular primary springs, can be tensioned in order to assemble or disassemble device parts without the primary springs acting on them. The arm tool preferably comprises a pneumatically, hydraulically or electrically driven actuator which has an actuator piston whose displacement axis is preferably adjustable. Preferably, the actuator piston is extendable perpendicular to the platform against the support element, so that a spring element mounted on the support element, in particular a primary spring of the bogie, is compressible.

In preferred embodiments, the arm tool is held by a support bar, which is connected at its underside by a support joint with the telescopic support and which is connected at its upper side with an adjusting device by means of which the orientation of the arm tool and thus the axis of displacement of Aktuatorkolbens is adjustable.

Each of the maintenance columns may have one or more lifting devices. For example, the gripping device of the service column is assigned a first lifting device. In a preferred embodiment, each pair of tool arms is associated with a second lifting device. The gripping devices and the tool arms can be moved vertically independently in this case. The bogie can raised by means of the gripping devices and deposited after the pivoting of the tool arms on this.

However, it is also possible to use only a single lifting device, with which the gripping devices and optionally the tool arms of a maintenance column are coupled.

If only the gripping devices are coupled to a lifting device, then the bogie can be driven by means of the gripping devices to the height of the tool arms, which are then rotated against the raised bogie.

However, the gripping devices and the pair of tool arms can also be driven by a common lifting device. In this case, the bogie is detected by the gripping devices and raised by operating the single lifting device to a working height. Subsequently, also raised by the single lifting tool arms are pivoted against the held bogie and coupled with this.

In particular, in the two cases described, in which a maintenance column has only a single lifting device for the gripping device and the two tool arms, the arm tool preferably comprises two actuators with two mutually displaceable actuator elements, optionally actuator pistons. The two actuator elements can subsequently be pressed against the bogie, e.g. be driven against one of the primary springs to compress them. The support element is formed in this case by one of the actuator elements.

The entire maintenance device, including the gripping devices, the tool arms, the arm tools and the lifting devices, can be fully automated. To reduce the effort, the inventive Maintenance device but preferably built as a semi-automatic. For example, only those parts are automated for which a drive device is mandatory. Preferably, at least the lifting devices and the arm tools are automatically driven and controlled. Extending the telescopic support and rotating the tool arms can be done manually.

The maintenance device can also be expanded and supplemented with additional tools.

Fig. 8

a part of the second maintenance column 1B of the maintenance device 10 of Fig. 6 with symbolically marked possibilities for manipulating the gripping device 2A and the in Fig. 7 shown tool arm 3A2.

Fig. 1 shows a maintenance device 10 according to the invention in a preferred embodiment with two by a platform 5 interconnected maintenance columns 1A, 1B, each having a first and a second lifting device 41, 42, a gripping device 2A; 2B and on opposite sides each have a first and a second pivotable tool arm 3A1, 3A2; 3B1, 3B2.

The platform 5 has a rail pair 51, 52, via which a bogie 9 can move in parallel to the longitudinal axis x of the maintenance device 10 between the maintenance columns 1A, 1B, as shown in FIG Fig. 2 is shown. It has already been described above that by means of the maintenance device 10 a bogie 9 can also be released from a railway carriage. It has also been stated that the maintenance columns 1A, 1B can be displaceably mounted on the platform 5, for example in rails, so that at one position a bogie can be released from a railroad car and maintained at another position.

For better illustration of in Fig. 1 Maintenance device 10 shown, the gripping devices 2A, 2B were moved up and the tool arms 3A1, 3A2; 3B1, 3B2 pivoted against each other in an orientation parallel to a transverse axis y, which is perpendicular to the longitudinal axis x of the maintenance device 10. The platform 5 is aligned parallel to a plane which is defined by the longitudinal axis x and the transverse axis y of the maintenance device 10.

In this embodiment, each of the gripping devices 2A, 2B is connected to a first lifting drive 41 and can be moved with it along guide rails 411 perpendicular to the platform 5.

The first lifting drive 41 comprises a spindle 412 driven by a spindle drive 414, which holds a bearing unit 413 with which the associated gripping device 2A; 2B is connected. The gripping device 2A; 2B may be fixedly connected to the bearing unit 413 or rotatably mounted therein about an axis which is parallel to the transverse axis y.

The bearing unit 413 preferably comprises a drive motor, by means of which the gripping device 2A; 2B can be turned. Additionally or alternatively, a locking device may be provided in the bearing unit 413, by means of which the Gripping device 2A; 2B can be fixed in a specific rotational position. A bogie 9 can therefore be locked in the respective rotational position and held securely, like this Fig. 4 shows.

The tool arms 3A1, 3A2; 3B1, 3B2 of each maintenance column 1A; 1B are held by a second lifting device 42 and connected to a guide carriage 423 which is guided along guide plates 421 and which is driven by a carriage drive 424. For example, the guide carriage 423 is provided with rollers and / or sliding elements which are mounted on the guide plates 421.

Like this in Fig. 8 2, guide plates 421 provided with guide tracks are mounted on opposite sides of the pillar body 4B of the service pillar 1B. The guide carriage 423 has two side plates 4231 arranged on opposite sides of the column body 4B, which engage in the guide plates 421 and which are interconnected by connecting webs 4232. The guide carriage 423 therefore encloses the column body 4B and is guided in the guide plates 421, which preferably each have a rack 422 into which the carriage drive 424 can engage. For example, the carriage drive 424 is fixedly connected to the guide carriage 423 and provided with a drive shaft which drives a gear which engages in the vertically aligned rack 422. By rotating the drive shaft of the carriage drive 424, the guide carriage 423 is moved vertically upwards or downwards along the rack 422 and the guide plates 421. The two maintenance columns 1A and 1B are preferably equipped identically.

Since some of the drive devices and optionally further electrical devices are not arranged stationary, but are displaceable, for example, with the gripping devices 2A, 2B and the guide carriage 423, these electrical units are via energy chains 45 with a power supply unit and preferably, wireless or wired, connected to a control unit 6 or connectable, as in Fig. 8 is shown.

In the Fig. 1 mutually rotated tool arms 3A1, 3A2; 3B1, 3B2 have a supporting element 32 serving for depositing the bogie 9 and an arm tool 31 serving to machine the bogie 9. The arm tool 31 comprises in this preferred embodiment, an actuator with an extendable Aktuatorkolben 311. In further preferred embodiments, the support member 32 may be formed by a further extendable Aktuatorkolben. In this case, two actuators are provided with mutually extendable Aktuatorkolben. In this case, it is not necessary that the bogie 9 is set down on the support elements 32 by means of the gripping devices 2A, 2B. Instead, the actuator elements, preferably the Aktuatorkolben be driven against each other to detect the bogie 9. In addition, holding plates can be provided on the actuator elements in order to ensure a secure reception of the chassis 91.

Fig. 1 further shows that the left service pillar 1A is higher than the right service pillar 1B. This embodiment is preferably provided when auxiliary tool, such as a crane or a camera to be attached to the left maintenance column 1A. The maintenance columns 1A, 1B are bolted to the platform 5. Alternatively, the maintenance columns 1A, 1B can also be connected rotatably and / or slidably in rails to the platform 5. For example, 5 maintenance columns may be mounted on a platform 5, of which the middle is rotatable. The middle maintenance column can be provided with devices that are not needed in the outer maintenance columns. In particular, when the two maintenance columns 1A, 1B are displaceable along the rails 51, 52, their upper ends are preferably connected to one another by a preferably detachable connecting device 40 (see FIG Fig. 2 ).

Fig. 2 shows the maintenance device 10 of FIG. 1 with a via the platform 5 between the maintenance columns 1A, 1B retracted bogie 9, which has two sets of wheels 90, each having a wheel axle 901 and two wheels 902. The bogie 9 has a chassis 91 with four wheel bearings 93, in which the ends of the wheel axles 901 of the wheelsets 90 are held. For sprung mounting of the chassis 91 this is connected via primary springs 92 with the axle bearings 93. To guide the wheel axles 901, the chassis 91 is further connected via axle link 94 with the axle bearings 93 (see Fig. 7 ).

The gripping devices 2A and 2B of the maintenance columns 1A, 1B have been moved down, but not yet against each other.

Fig. 3 shows the maintenance device 10 of FIG. 2 with the raised chassis 91 of the bogie 9 and the wheelset 90 released from the bogie 9 remaining on the platform 5 in the rails 51, 52. To grasp the chassis 91, the gripping devices 2A and 2B were moved against each other along the transverse axis y, as will be described below.

Fig. 4 shows the maintenance device 10 of FIG. 3 with the bogie 9 raised and rotated about 135 °, after the wheelsets 90 have been rolled away. The bogie 9 can therefore be rotated by 360 ° to a position in which the maintenance personnel have optimum access to the device parts that need to be serviced or replaced. It can be seen that the lower bearing shells of the bearing devices 93 have been removed so that the wheel axles 901 of the wheel sets 90 could be released. By contrast, the primary springs 92 are still under tension, which is why the associated device parts can not and should not be dismantled since the release of the energy stored in the primary springs 92 is associated with a high risk potential. To release these parts of the device, the bogie 9 is further rotated in the supine position to the height the tool arms 3A1, 3A2, 3B1, 3B2 driven, after which they are rotated against the chassis 91 in a position in which the arm tools 31 provided thereon can act optimally on the bogie 9.

Fig. 5a shows the maintenance device 10 from above and the underside of the rotated by 180 ° bogie 9. The tool arms 3A1, 3A2, 3B1, 3B2 were rotated against the bogie 9 so that the arm tools 31 and the actuators 31 with the Aktuatorkolben 311 coaxial with the Primary springs 92 of the bogie 9 are aligned. After aligning the tool arms 3A1, 3A2, 3B1, 3B2, the bogie 9 can continue to be driven downwards by means of the gripping devices 2A, 2B until the chassis 91 rests on the support elements 32 of the tool arms 3A1, 3A2, 3B1, 3B2. If, on the other hand, the tool 31 has two actuators directed against one another, then the actuator pistons 311 can be moved against the chassis 91 from above and from below (see also FIG Fig. 8 ). In this case, the one or both Aktuatorkolben 311 are driven against device parts which are connected to the ends of the primary springs 92. As a result, these device parts and the primary springs 92 are further pressed against each other until the spring force of the primary springs 92 is completely absorbed by the tool 31. After this process, all connected to the primary springs 92 device parts can be solved safely with little effort.

Fig. 5b shows the maintenance device 10 of FIG. 5a with the chassis 91 of the bogie 9 held by the tool arms 3A1, 3A2, 3B1, 3B2 and the partially extended actuator piston 311.

Fig. 6 shows a part of the maintenance device of Fig. 5a with the second service pillar 1B and a section through the chassis 91 of the bogie 9 along the in Fig. 5b drawn section line AA. The section runs on the relevant side of the bogie 9 through the axle guide 94, the handlebar shafts 912, the chassis cross members 911 and the primary springs 92. After the further extension of the actuator piston 31 against the primary springs 92 whose spring force can be absorbed by the tools 31 of the tool arms 3A1, 3A2, 3B1, 3B2. The axle links 94, which are connected to the chassis 91 by a link shaft 912, can then be decoupled from the primary springs 92. Furthermore, device parts can be solved by means of which the bias of the primary springs 92 was maintained. Fig. 6 further shows damping devices 95, by means of which the remote bearing shell of the wheel bearing 93 was connected to the chassis 91 in order to damp vibrations of the axle guide 94.

Fig. 7 shows one of the tool arms 3B1 of the second maintenance column 1B of the maintenance device 10 with a part of the chassis 91 of the bogie 9 in the sectional view of Fig. 6 , In a detailed illustration, a contact sensor 321, 322 arranged on the support element 32 of the tool arm 3A2 is also shown larger, which has a finger 322 guided through the support element 32 and a switch 321 connected thereto. By means of the finger 322, the settling of the chassis 91 on the tool arms 3A1, 3A2, 3B1, 3B2 is scanned and transmitted to the switch 321, which emits a corresponding electrical signal wired or wireless to the control unit 6. By means of the switching signals transmitted by the switches 321, the control unit 6 recognizes the setting down of the chassis 91 and can take this into account in the further control of the maintenance device 10.

Fig. 8 shows a part of the second maintenance column 1B of the maintenance device 10 of Fig. 6 with options for manipulating the gripping device 2B and the in Fig. 7 shown tool arm 3B1. The second tool arm 3B2 has been disassembled, so that the associated arm joint 39 held by the arm 34 is freely visible. The manipulation possibilities of the gripping device 2B and the tool arm 3B1 are illustrated by arrows.

The gripping device 2A has a telescopic holder 20 with two telescoping first and second telescopic elements 201, 202. The second telescopic element 202 is connected to a bar-shaped holding element 21, along which two gripper tools 211, 212 are displaceable parallel to the longitudinal axis x. The holding element 21 can therefore by extending the telescopic elements 201, 202 along the transverse axis y (see Fig. 1 ) are pulled against a bogie 9. As a result, the gripping tools 211, 212 can be displaced along the holding element 21 until a suitable position for holding the bogie 9 is reached. Subsequently, the symbolically shown gripping tools 211, 212 are preferably closed in order to keep the chassis 91 of the bogie 9 safe. After grasping the bogie 9 this can be rotated about an axis of rotation which is coaxial with the telescopic elements 201, 202 of the telescopic support 20 (see Fig. 4 ).

The preferably configured tool arm 3B1 is connected to the pillar body 4B of the second service pillar 1B through the wrist joint 39 and the boom 34. The arm joint 39 is arranged such that the tool arm 3B1 is rotatable in a plane parallel to the platform 5.

The tool arm 3B1 comprises a telescopic support 30 with a first and a second telescope part 301, 302. The second telescope part 302, which is preferably slidably mounted in the first telescope part 301 by means of rollers and which carries the arm tool 31 and the support element 32, can be made from the first telescope part 301 are pulled out. The tool arm 3B1 can therefore be rotated and extended as needed until the tool 31 has reached a desired position, as is Fig. 5a shows. As a result, the actuator piston 311 of the tool 31, which is supplied with energy via a power line 312, can be extended against the support element 32 or against the chassis 91 of the bogie 9. The tool 31 is mounted on a top plate 37, which has a support beam 35 and a support joint 38 with the second Telescope part 302 is rotatably connected. The inclination of the support beam 35 and thus of the tool 31 can be adjusted by means of an adjusting device 36, which is pivotally connected to the second telescopic part 302 and the top of the support beam 35.

On the support plate 32, a second tool 31 ', which in Fig. 8 is shown separately, for example, mounted in the same way as the first tool 31 is connected to the top plate 37. The Aktuatorkolben 311 of the two mounted actuators 31, 31 'can be extended against each other to detect the chassis 91 of the bogie 9.

In Fig. 8 Furthermore, a control device 6 is shown, which is operated by a representative of the maintenance personnel. By means of the control device 6 can be operated via radio signals, for example via a Bluetooth network, preferably all drive units of the maintenance device 10.

With reference to the drawings, typical operations have been described which may be advantageously practiced by the maintenance device 10. However, the maintenance device 10 allows to perform practically all necessary maintenance work advantageous. It is possible to provide the maintenance device with other tools, such as a bearing take-off device.
