The bolt (10b, 10c) and the bushing (3k, 31) are designed in such a manner that the connection between the running gears (2a, 2b, 2c) and the body (3) can be created by a relative movement of the running gears (2a, 2b, 2c) and the body (3) parallel to the vertical axis (A).
Description
Current collector carriage having detachably fastened running gears The invention relates to a current collector carriage having travelling mechanisms releasably connected to a body, the current collector carriage being displaceable along a collector carriage being in electrical contact with the current conductors, wherein the travelling mechanisms can be pivoted relative to the body in each case about an axis of the current collector carriage, the axis is aligned vertically with respect to a plane which extends horizontally with respect to the current collector carriage aligned with its German patent document DE 199 64 581 B4 discloses a current collector carriage having travelling mechanisms attached in a positive-locking and releasable manner for the linear current strengths. For mechanical coupling of the current collector carriages to each other, an upper and a lower groove are each provided on a front and a rear outer side of the housing of each current collector carriage, which carriages, opposite one another, each point in a displacement direction. The grooves are aligned horizontally and transversely with respect to the displacement directions and are formed to be dovetail-shaped in cross-section. Profiled coupling parts, formed in a rod-like manner, can be releasably slid into the grooves in the longitudinal direction thereof. The profiles of the coupling parts are formed complementarily to the dovetail-shape of the grooves, i.e., they are also dovetail-shaped. In order to couple two successive current collector carriages to each other, a connecting body comprises a front and a rear coupling part, which coupling parts are opposite each other and point away from each other. In addition, elongate latch arms can be formed on the coupling parts, which latch arms extend in the longitudinal direction thereof. Each latch arm comprises a free and resilient end having a region protruding in lug-shaped manner and pointing away from the coupling part in the direction of the housing and, after being slid-in sufficiently far, snapping behind a protrusion of the groove set back in a stepped manner. Owing to the hook effect of the latch arms, withdrawal of the coupling part in the direction opposite the sliding-in direction is only possible by actively bending the latch arm in the direction pointing away from the housing. The grooves can also be used to releasably attach wheel sets to the current collector carriage. In a corresponding manner, the coupling part is then attached to a travelling mechanism as an integral component of a supporting body of a wheel set.
Swiss patent document CH 277 125 A discloses a current collector carriage to whose body two travelling mechanisms are releasably and pivotably attached. The body and also the travelling mechanisms comprise sleeve sections which are disposed one above the other and separated from each other by cut-outs. For assembly, the travelling mechanisms and the body are moved towards each other in the horizontal direction so that the sleeve sections engage within one another in the manner of a finger joint. The through-going bores of the sleeve sections are disposed so as to be centred one above the other. The travelling mechanisms are attached to the body in the manner of a hinge joint via a separate pin which is slid through the sleeve sections in the vertical direction and forms a vertical pivot axis.
The object of the invention is to provide an improved current collector carriage having releasably attached travelling mechanisms.
This object is achieved by a current collector carriage having the features of claim 1.
Advantageous embodiments of the invention are described in subordinate claims 2 to 12.
In accordance with the invention, an improved current collector carriage having travelling mechanisms releasably connected to a body, the current collector carriage being displaceable along a rail having several current conductors via the travelling mechanisms and the current collector carriage being in electrical contact with the current conductors, wherein the travelling mechanisms can be pivoted relative to the body in each case about an axis of the current collector carriage, the axis is aligned vertically with respect to a plane which extends horizontally with respect to the current collector carriage aligned with its longitudinal extension in a displacement direction and the travelling mechanisms are connected to the body via a sleeve engaged with a pin, is achieved by virtue of the fact that the pin and the sleeve are formed such that the connection between the travelling mechanisms and the body can be produced by a relative movement of the travelling mechanisms and of the body in parallel with the vertical axis. For example in the case of a design configured in a modular manner within a unit assembly system, a particularly rapid and simple assembly is hereby possible.
In an advantageous embodiment, the travelling mechanisms are connected to the body in the manner of a hinge joint.
Changing between straight travel and travel on a curve is improved by virtue of the fact that a resilient restoring element is provided which co-operates with the pin and the sleeve such that the travelling mechanisms are automatically aligned in the displacement direction when the current collector carriage is travelling in a straight line.
A particularly smooth pivotability, and thus ability to negotiate curves, is achieved by virtue of the fact that the pin has a round cross-section and extends with its longitudinal extension in parallel with the axis.
Further optimisation of the assembly is achieved by virtue of the fact that the travelling mechanisms can be connected to the body in a positive-locking manner. A
process, which is to be performed rapidly hereby, of replacing the travelling mechanisms or wheel sets in the case of wear or changing intended use results in simple maintenance and particularly user-friendly operation of the current collector carriage.
In an advantageous embodiment, the sleeve is open at an end pointing in a longitudinal direction of the sleeve and the pin can be slid into the sleeve through the open end.
In a constructionally simple design, the sleeve comprises a wall having a slot-shaped cut-out which goes through the wall beginning at a first edge partially or completely in the vertical direction having a width and through which a supporting body connected to the pin is guided, which supporting body is supported with an upper edge on a third edge of the sleeve.
In order to extend the possible uses of current collector carriages, it is advantageous that a third travelling mechanism includes two pins which are arranged opposite each other at the front and rear in the displacement direction of the current collector carriage.
In order to string together several current collector carriages in a constructionally simple manner, it is advantageous that a first current collector carriage and at least one second current collector carriage can be connected together by means of the third travelling mechanism. In this manner, trains of current collector carriages can be formed in accordance with the principle of railways, whereby it is possible to handle different current strengths as required and so as to be adapted to the intended use.
For a standardised configuration of the current collector carriage, it is advantageous that the pins are disposed on the travelling mechanisms and the sleeves are disposed on the body of the current collector carriage or the pins are disposed on the body of the current collector carriage and the sleeves are disposed on the travelling mechanisms.
In a particularly advantageous embodiment, running wheels and guide wheels are disposed on each travelling mechanism.
For a reliable current flow or control signal flow, it is advantageous that the current collector carriage is in current-conducting sliding contact with the current conductors via contact means disposed on the current collector carriage.
An exemplified embodiment of the invention will be described in more detail with the aid of the following description. In the drawings:
Figure 1 shows a perspective view of a current collector carriage, which can be displaced along a rail, for supplying current to a crane trolley of a bridge crane, Figure 2 shows a partial sectional view of the current collector carriage of Figure 1 with a rail in cross-section, Figure 3 shows a perspective view of a current collector carriage having travelling mechanisms, Figure 4 shows a perspective view of a body of the current collector carriage of Figure 2, Figure 5a shows a perspective view of a travelling mechanism in a first embodiment, Figure 5b shows a perspective partial view of a travelling mechanism in a second embodiment, Figure 6 shows a perspective view of two coupled current collector carriages of Figure 1, and Figure 7 shows a view of the travelling mechanism between the two current collector carriages of Figure 6.
Figure 1 shows a perspective view of a first current collector carriage 1a which can be displaced along a current-carrying rail 4 in two displacement directions V, which are substantially horizontal and are opposite one another, via travelling mechanisms 2a, 2b (see Figure 3) covered by the current-carrying rail 4. The rail 4 is formed to be c-shaped in cross-section and open at the bottom. The rail 4, formed in this manner as a hollow profile, thus delimits an inner space 4j in which the current collector carriage la is displaced. In the inner space 4j, five current conductors 5a to 5e are attached, extend in parallel with each other in the longitudinal direction of the rail 4 and are distributed spaced apart from each other over the c-shaped profile of the rail 4. The current conductors 5a to 5e are connected as required to a current source or a controller in order to supply current or control signals. The only part of the current collector carriage la which can be seen is a housing 14 which surrounds a connection part 13 of a body 3 protruding downwards from the rail 4. Disposed on the body 3 are five contact means 6a to 6e (see Figure 2) in order to establish a direct sliding contact between the contact means 6a to 6e and the current conductors 5a to 5e during the displacement of the current collector carriage la along the rail 4.
A crane trolley 15 of a bridge crane, which trolley can be displaced on two running rails 15a, 15b in the displacement directions V, is supplied with current and/or control signals via the current collector carriage la. The crane trolley 15 comprises at least one motor 16 for a travelling drive and/or a lifting drive. In order for the current collector carriage la to be able to be displaced together with the crane trolley 15 along the rail 4, the current collector carriage la is mechanically connected to the crane trolley 6 via two rod-shaped entrainers 15c, 15d. In order to transfer current and/or control signals, the current collector carriage la is connected to the motor 16 via an electrical line 12.
The electrical line 12 is connected to the connection part 13 of the current collector carriage la.
Figure 2 shows a view of the current collector carriage la of Figure 1 which is disposed in a rail 4 illustrated in cross-section. The rail 4 is formed as a hollow profile having the substantially rectangular inner space 4j and is formed to be c-shaped and open at the bottom. Accordingly, the rail 4 comprises a horizontal upper web wall 4a to which a left, vertical, first limb wall 4b and a right, vertical, second limb wall 4c are connected.
Connected to the ends of the limb walls 4b, 4c remote from the web wall 4a are a first connection wall 4d and a second connection wall 4e, both directed horizontally inwardly, such that a downwardly-directed slot-shaped opening 4k is formed along the rail 4 between the connection walls 4d, 4e. The web wall 4a accommodates the fifth current conductor 5e on the inner side, the first limb wall 4b accommodates the second and third current conductors 5b, 5c on the inner side and the second limb wall 4c accommodates the first and fourth current conductors 5a, 5d on the inner side. The inner sides of the web wall 4a and the connection walls 4d, 4e are used as horizontal running surfaces 4f to 4i for wheel sets 7a, 8a of the current collector carriage la. Shown in particular are the first running surface 4f on the first connection wall 4d and the second running surface 4g on the second connection wall 4e for the lower, first wheel sets 7a, via which the current collector carriage la is displaced in the rail 4, and the third and fourth running surfaces 4h, 4i on the web wall 4a for the upper, second wheel sets 8a, via which the current collector carriage la is guided in the rail 4.
It can also be seen that the current conductors 5a to 5e are held in clamp-like undercuts 41. Adjoining the current conductors 5a to 5e are the contact means 6a to 6e for transferring current and/or control signals between the current conductors 5a to 5e and the current collector carriage la. The contact means 6a to 6e are resiliently mounted in the direction of the current conductors 5a to 5e in pockets 3f to 3j (see also Figures 3 and 4) of the body 3 of the current collector carriage la.
It is also shown that a part of the body 3 referred to as the support 3a protrudes downwards from the rail 4 between the walls 4d, 4e and is connected to the electrical line 12 (see Figure 1) and the housing 14.
Figure 3 shows a perspective view of the current collector carriage la of Figure 1 having the travelling mechanisms 2a, 2b which are releasably connected to the body 3 of the current collector carriage la at the front and rear as seen in the displacement direction V.
The current collector carriage la is supported by the two travelling mechanisms 2a, 2b and can be displaced thereby along the current-carrying rail 4. The body 3 includes the flat support 3a having an upper, first end 3b and a lower, second end 3c, on which a first and a second thin-walled supporting wall 3d, 3e are arranged laterally, i.e., in the displacement direction V, such that a T-shaped design of the body 3 is produced. The supporting walls 3d, 3e extend in opposite directions directed away from the support 3a in each case in one of the displacement directions V. Disposed on the body 3 are the five pockets 3f to 3j which are each formed in the shape of a container and cuboid, are open on one side and are used to receive the contact means 6a to 6e. The first supporting wall 3d has the first pocket 3f passing through it at the bottom and the second pocket 3g passing through it at the top and the second supporting wall 3e has the third pocket 3h passing through it at the bottom and the fourth pocket 3i passing through it at the top.
The openings of the first and second pockets 3f, 3g and of the third and fourth pockets 3h, 3i each point in mutually opposite horizontal directions transverse to the displacement directions V, wherein at the same time the openings of the upper second and fourth pockets 3g, 3i and the openings of the lower first and third pockets 3f, 3h each point in mutually opposite directions. Disposed on the first end 3b of the support 3a between the supporting walls 3d, 3e is the upwardly-opened fifth pocket 3j.
Receiving connecting means in the form of a first and a second sleeve 3k, 31 are disposed in each case on a vertical edge of the supporting walls 3d, 3e pointing away from the support 3a - and thus at the front and rear on the current collector carriage la. The sleeves 3k, 31 are identical in construction having a circular cross-section and are formed in a hollow-cylindrical manner with an inner bore. In the case of a current collector carriage la in a horizontally extending rail 4, the inner bores are aligned vertically with respect to their longitudinal extension. The sleeves 3k, 31 also each have a lower, first edge 3m and an upper, second edge 3n (see Figure 4). Each sleeve 3k, 31 is supported in the transition region between the sleeves 3k, 31 and the supporting wall 3d, 3e by a reinforcement 3t. The mutually opposite end sides, pointing in opposite vertical longitudinal directions of the sleeves 3k, 31, are open.
The first travelling mechanism 2a is attached to the first sleeve 3k and the second travelling mechanism 2b is attached to the second sleeve 31. The travelling mechanisms 2a, 2b are identical in construction and each comprise a vertical and wall-like supporting body 9 (see Figures 5a and 5b) in which a lower, first wheel set 7a having two lower running wheels 7b, 7c and an upper, second wheel set 8a having two upper guide wheels 8b, 8c are accommodated in a rotatably-mounted manner. A cylindrical first pin 10b, not illustrated, (see Figures 5a and 5b) is attached to the supporting body 9 as a rigidly formed connecting means to be received. Disposed between the first and second guide wheels 8b, 8c is a flat, plate-shaped tongue 17 which is used as an entrance aid when entering a funnel-shaped region of the rail 4. Of course, the travelling mechanisms 2a, 2b can also operate without a tongue 17 of this type. The design of the travelling mechanisms 2a, 2b is illustrated in detail in Figures 5a and 5b. The outer diameter of the pin 10b is smaller than the inner diameter of the sleeve 3k, 31. The pin 10b is slid into the sleeve 3k, 31 from the lower, first edge 3m until the supporting body 9, which protrudes outwards through a vertical, slot-shaped cut-out 3o provided in the sleeve 3k, 31 and is guided through the cut-out 3o, abuts with an upper edge against a third edge 3q (see Figure 4) and the body 3 is thus supported on the supporting body 9 via the edge 3q. The travelling mechanisms 2a, 2b are connected in this manner in a positive-locking manner to the current collector carriage la at least in one embodiment. The supporting body 9 and thus the travelling mechanisms 2a, 2b are disposed on the body 3 in an articulated manner and can be pivoted in a hinge-like manner about a vertical axis A
within an angle a (see Figure 4) dependent upon a width B (see Figure 4) of the cut-out 3o and the dimensions of the supporting body 9. In other words, the pivotability of the travelling mechanisms 2a, 2b is limited by the geometric configuration of the cut-out 3o.
The axis A is embodied by the pin 10b or a vertical central axis of the pin 10b and coincides with a central axis of the sleeve 3k, 31.
However, the axis A does not have to coincide concentrically with the central axes of the receiving connecting means and the connecting means to be received or of the sleeve 3k, 31 and of the pin 10b. It is also possible that the axis A extends through one of the connecting means but is located eccentrically with respect to any central axes of the connecting means. In the case of a reconfigured cut-out 3o, the pin 10b can be slid into the sleeve 3k, 31 starting from the upper, second edge 3n. It is also possible to provide a pivoting mechanism whose hinged movement is actively achieved in a positive-locking or non-positive-locking manner in another way - without a supporting body 9 protruding through a cut-out 3o. Of course, it is also possible to dispose the sleeves 3k, 31 on the travelling mechanism-side and in each case to dispose a supporting body 9 with a pin 10b on the body 3.
On a side of the travelling mechanism 2a, 2b opposite the wheel sets 7a, 8a, a second groove 3u extending in the longitudinal direction of the pin 10b and being disposed radially with respect to the axis A can be provided on the pin 10b in a second embodiment (see Figure 5b). As seen in this radial direction, the cross-section of the second groove 3u, starting from the peripheral surface, has a funnel-shaped region extending into the interior of the pin 10b, which region is adjoined by a rectangular cross-sectional region (see Figure 5b). When the travelling mechanism 2a, 2b is connected to the body 3 and is not pivoted-out, the second groove 3u is disposed opposite a first groove 3p which is provided in the sleeve 3k, 31, also extends vertically and has a rectangular cross-section. An elongate and cuboid restoring element 18 having a cross-section formed in a complementary manner with respect to the first groove 3p can be slid into the first groove 3p and protrudes into the interior of the sleeve 3k, 31 in a web-like manner in the radial direction. The restoring element 18 consists of a resiliently deformable material, e.g., a rubber material. When the body 3 and the travelling mechanism 2a, 2b are brought together, the restoring element 18 attached in the second groove 3u is connected to the first groove 3p of the sleeve 3k, 31in a positive-locking manner. Owing to the co-operation of the restoring element 18 with the first groove 3p, a resiliently pivotable positioning of the travelling mechanisms 2a, 2b is permitted. The restoring element 18 assumes in particular a restoring function, whereby the deflection of the travelling mechanisms 2a, 2b about the angle a set during travel on a curve is automatically cancelled during travel in a straight line. In other words, owing to the described arrangement of the restoring element 18, the travel of the first current collector carriage la in a straight line is fixed as a state of equilibrium in which the restoring element 18 is in a non-loaded state which is automatically set as soon as travel on a curve ends and the occurring outer force application upon the restoring element 18 is cancelled.
Therefore, the travelling mechanisms 2a, 2b are automatically aligned in the displacement direction V by the restoring force of the spring element 18. The elastically-resilient restoring effect or inner restoring force of the restoring element 18 can be varied e.g., by the selection of different materials having correspondingly different material characteristics or by adapting the geometric dimensions, in particular the length of the restoring element 18.
Additionally provided on the support 3a on two sides pointing transversely with respect to the displacement directions V are two horizontal bearing plates 3r, 3s which are identical in construction and are spaced apart from each other in parallel and between which in each case a horizontal, third, lateral guide wheel 11 is accommodated in a rotatably mounted manner.
The contact means 6a to 6e of the current collector carriage la are connected in a conductive manner in each case to a first end, not illustrated, of a current cable. All of the current cables are consolidated in the electrical line 12 which is connected to the system to be supplied with current. The electrical line 12 is connected to the current collector carriage la via a connection part 13 (see Figure 4) located on the lower, second end 3c. The connection point is surrounded by the housing 14.
Figure 4 illustrates a perspective view of the body 3 without the travelling mechanisms 2a, 2b, 2c. The support 3a, the supporting walls 3d, 3e adjoining the support and the pockets 3f to 3j disposed on the supporting walls 3d, 3e, in particular the openings of the pockets 3f, 3i, 3j can clearly be seen in particular.
In addition, the vertical, slot-shaped cut-out 3o having the minimum width B
is provided in a sleeve wall of the sleeve 3k, 31. The cut-out 3o is arranged such that it points away from the support 3a in one of the displacement directions V, beginning at the horizontal, lower, first edge 3m, interrupts the latter whilst extending upwards and is delimited at the top by the central, likewise horizontal, third edge 3q which is offset in parallel with the first edge 3m. The vertically extending first groove 3p having a rectangular cross-section is provided in the interior of the sleeves 3k, 31 and is disposed opposite the cut-out 3o and extends in a plane with the supporting wall 3d, 3e.
The cut-out 3o in the sleeve 3k, 31 has a height H which is a result of the distance of the lower, first edge 3m from the central, third edge 3q, which means that a closed and regular peripheral surface remains only above the cut-out 3o between the central, third edge 3q and the upper, second edge 3n. The angle a is formed by a notional line, which extends in a plane with the supporting walls 3d, 3e and intersects the axis A, and an inner side of the cut-out 3o of the sleeve 3k, 31. The decisive feature is the width B (see also Figure 6) of the inner side as the minimum horizontal dimension of the cut-out 3o.
It is also possible that the cut-out 3o extends in a continuous manner in the vertical direction, also interrupts the second edge 3n and does not produce a third edge 3q. The vertically divided peripheral surface of the sleeve 3k, 31 thus forms two resilient latch arms which permit accommodation of the pin 10b e.g., in the form of a snap-fit connection or clip-connection by positive-locking or non-positive-locking assembly in one of the displacement directions V. The downwardly directed connection part 13 on the second end 3c of the support 3 is also illustrated.
Figure 5a shows the first and second travelling mechanism 2a, 2b having the wheel sets 7a, 8a which are each connected to the supporting body 9 lying one above the other. The pin 10b, which is vertically aligned in its longitudinal extension, is disposed on a vertical side of the supporting body 9 spaced apart from the wheel sets 7a, 8a.
Figure 5b illustrates a partial view of the connection between the first/second travelling mechanism 2a, 2b in the third embodiment having the body 3 in a pivoted-out position.
The restoring element 18 is particularly shown and is disposed in the first groove 3p of the sleeve 3k, 31 and is simultaneously accommodated by the second groove 3u of the pin 10b. Furthermore, it can be seen that the restoring element 18 is deformed owing to a deflection or rotation of the pin 10b with respect to the sleeve 3k, 31 or about the axis A
and by the angle a.
Figure 6 shows the first current collector carriage la having a first travelling mechanism 2a and a second current collector carriage lb having a second travelling mechanism 2b.
The current collector carriages la, lb can be displaced on a curved track K
and are coupled together via a third travelling mechanism 2c. The third travelling mechanism 2c includes - in a similar manner to the supporting body 9 of the travelling mechanisms 2a, 2b - a wall-like connecting web 9a. The shape of the connecting web 9a resembles two assembled supporting bodies 9 forming a vertical axis of symmetry. Disposed on two ends of the connecting web 9a facing away from each other are in each case the first pin 10b and a second pin 10c which are vertically aligned with respect to their longitudinal extension. The connecting web 9a accommodates, between the pins 10b, 10c and along the axis of symmetry, two wheel sets 7a, 8a so that these are rotatably mounted one above the other. In order to connect the two current collector carriages la, lb together, the pin 10b is slid into the sleeve 31 of the first current collector carriage la and the pin 10c is slid into the sleeve 3k of the second current collector carriage lb. The pins 10b, 10c are identical in construction to the first embodiment, and thus comprise a regular peripheral surface. There is thus no positive-locking connection between the pins 10b, 10c and the first groove 3p, whereby the travelling mechanism 2c can be pivoted with respect to the current collector carriages la, lb within the angle a (see also Figure 7). Of course - in a similar manner to the configuration of the travelling mechanisms 2a, 2b - it is also possible to provide the pins 10b, 10c in each case with a second groove 3u and a restoring element 18 in order to permit an elastically-resilient pivotability of the travelling mechanism 2c with respect to the current collector carriages la, lb.
Figure 7 shows a view of the current collector carriages la, lb coupled via the pins 10b, 10c of the third travelling mechanism 2c. The connecting web 9a of the travelling mechanism 2c without the wheel sets 7a, 7b is shown in a position pivoted-out with respect to the supporting walls 3d, 3e. In addition, the axis A illustrated as a dot and the width B of the cut-out 3o are identified. At the maximum possible deflection with the angle a, the connecting web 9a adjoins one of the inner sides of the cut-out 3o of the sleeve 31. A similar situation occurs for the angle ratios on the sleeve 3k between the connecting web 9a and the first supporting wall 3d of the second current collector carriage lb.
The variable setting of elastically-resilient and non-resilient pivotability of the travelling mechanisms 2a, 2b, 2c with respect to the body 3 is preferably produced by an application-specific exchange or use of travelling mechanisms 2a, 2b, 2c formed in a correspondingly modular manner. In other words, the corresponding type of pivotability is thus produced by the described connections between two intrinsically rigid connecting means - e.g., between the pins 10b, 10c slid into the sleeves 3k, 31 and rotatable therein and having the second groove 3u for the restoring element 18 provided thereon.
In addition to the substantially horizontal alignment described above, the mutually opposite displacement directions V can of course be aligned to be non-horizontal and thus form different degrees of inclination.
Also, the travelling mechanisms 2a, 2b, 2c can be connected to the body 3 not only by a relative movement of the travelling mechanisms 2a, 2b, 2c and of the body 3 in parallel with the axis A but also transversely with respect to the axis A.

Swiss patent document CH 277 125 A discloses a current collector carriage to whose body two travelling mechanisms are releasably and pivotably attached. The body and also the travelling mechanisms comprise sleeve sections which are disposed one above the other and separated from each other by cut-outs. For assembly, the travelling mechanisms and the body are moved towards each other in the horizontal direction so that the sleeve sections engage within one another in the manner of a finger joint. The through-going bores of the sleeve sections are disposed so as to be centred one above the other. The travelling mechanisms are attached to the body in the manner of a hinge joint via a separate pin which is slid through the sleeve sections in the vertical direction and forms a vertical pivot axis.
The object of the invention is to provide an improved current collector carriage having releasably attached travelling mechanisms.
This object is achieved by a current collector carriage having the features of claim 1.
Advantageous embodiments of the invention are described in subordinate claims 2 to 12.
In accordance with the invention, an improved current collector carriage having travelling mechanisms releasably connected to a body, the current collector carriage being displaceable along a rail having several current conductors via the travelling mechanisms and the current collector carriage being in electrical contact with the current conductors, wherein the travelling mechanisms can be pivoted relative to the body in each case about an axis of the current collector carriage, the axis is aligned vertically with respect to a plane which extends horizontally with respect to the current collector carriage aligned with its longitudinal extension in a displacement direction and the travelling mechanisms are connected to the body via a sleeve engaged with a pin, is achieved by virtue of the fact that the pin and the sleeve are formed such that the connection between the travelling mechanisms and the body can be produced by a relative movement of the travelling mechanisms and of the body in parallel with the vertical axis. For example in the case of a design configured in a modular manner within a unit assembly system, a particularly rapid and simple assembly is hereby possible.
In an advantageous embodiment, the travelling mechanisms are connected to the body in the manner of a hinge joint.
Changing between straight travel and travel on a curve is improved by virtue of the fact that a resilient restoring element is provided which co-operates with the pin and the sleeve such that the travelling mechanisms are automatically aligned in the displacement direction when the current collector carriage is travelling in a straight line.
A particularly smooth pivotability, and thus ability to negotiate curves, is achieved by virtue of the fact that the pin has a round cross-section and extends with its longitudinal extension in parallel with the axis.
Further optimisation of the assembly is achieved by virtue of the fact that the travelling mechanisms can be connected to the body in a positive-locking manner. A
process, which is to be performed rapidly hereby, of replacing the travelling mechanisms or wheel sets in the case of wear or changing intended use results in simple maintenance and particularly user-friendly operation of the current collector carriage.
In an advantageous embodiment, the sleeve is open at an end pointing in a longitudinal direction of the sleeve and the pin can be slid into the sleeve through the open end.
In a constructionally simple design, the sleeve comprises a wall having a slot-shaped cut-out which goes through the wall beginning at a first edge partially or completely in the vertical direction having a width and through which a supporting body connected to the pin is guided, which supporting body is supported with an upper edge on a third edge of the sleeve.
In order to extend the possible uses of current collector carriages, it is advantageous that a third travelling mechanism includes two pins which are arranged opposite each other at the front and rear in the displacement direction of the current collector carriage.
In order to string together several current collector carriages in a constructionally simple manner, it is advantageous that a first current collector carriage and at least one second current collector carriage can be connected together by means of the third travelling mechanism. In this manner, trains of current collector carriages can be formed in accordance with the principle of railways, whereby it is possible to handle different current strengths as required and so as to be adapted to the intended use.
For a standardised configuration of the current collector carriage, it is advantageous that the pins are disposed on the travelling mechanisms and the sleeves are disposed on the body of the current collector carriage or the pins are disposed on the body of the current collector carriage and the sleeves are disposed on the travelling mechanisms.
In a particularly advantageous embodiment, running wheels and guide wheels are disposed on each travelling mechanism.
For a reliable current flow or control signal flow, it is advantageous that the current collector carriage is in current-conducting sliding contact with the current conductors via contact means disposed on the current collector carriage.
An exemplified embodiment of the invention will be described in more detail with the aid of the following description. In the drawings:
Figure 1 shows a perspective view of a current collector carriage, which can be displaced along a rail, for supplying current to a crane trolley of a bridge crane, Figure 2 shows a partial sectional view of the current collector carriage of Figure 1 with a rail in cross-section, Figure 3 shows a perspective view of a current collector carriage having travelling mechanisms, Figure 4 shows a perspective view of a body of the current collector carriage of Figure 2, Figure 5a shows a perspective view of a travelling mechanism in a first embodiment, Figure 5b shows a perspective partial view of a travelling mechanism in a second embodiment, Figure 6 shows a perspective view of two coupled current collector carriages of Figure 1, and Figure 7 shows a view of the travelling mechanism between the two current collector carriages of Figure 6.
Figure 1 shows a perspective view of a first current collector carriage 1a which can be displaced along a current-carrying rail 4 in two displacement directions V, which are substantially horizontal and are opposite one another, via travelling mechanisms 2a, 2b (see Figure 3) covered by the current-carrying rail 4. The rail 4 is formed to be c-shaped in cross-section and open at the bottom. The rail 4, formed in this manner as a hollow profile, thus delimits an inner space 4j in which the current collector carriage la is displaced. In the inner space 4j, five current conductors 5a to 5e are attached, extend in parallel with each other in the longitudinal direction of the rail 4 and are distributed spaced apart from each other over the c-shaped profile of the rail 4. The current conductors 5a to 5e are connected as required to a current source or a controller in order to supply current or control signals. The only part of the current collector carriage la which can be seen is a housing 14 which surrounds a connection part 13 of a body 3 protruding downwards from the rail 4. Disposed on the body 3 are five contact means 6a to 6e (see Figure 2) in order to establish a direct sliding contact between the contact means 6a to 6e and the current conductors 5a to 5e during the displacement of the current collector carriage la along the rail 4.
A crane trolley 15 of a bridge crane, which trolley can be displaced on two running rails 15a, 15b in the displacement directions V, is supplied with current and/or control signals via the current collector carriage la. The crane trolley 15 comprises at least one motor 16 for a travelling drive and/or a lifting drive. In order for the current collector carriage la to be able to be displaced together with the crane trolley 15 along the rail 4, the current collector carriage la is mechanically connected to the crane trolley 6 via two rod-shaped entrainers 15c, 15d. In order to transfer current and/or control signals, the current collector carriage la is connected to the motor 16 via an electrical line 12.
The electrical line 12 is connected to the connection part 13 of the current collector carriage la.
Figure 2 shows a view of the current collector carriage la of Figure 1 which is disposed in a rail 4 illustrated in cross-section. The rail 4 is formed as a hollow profile having the substantially rectangular inner space 4j and is formed to be c-shaped and open at the bottom. Accordingly, the rail 4 comprises a horizontal upper web wall 4a to which a left, vertical, first limb wall 4b and a right, vertical, second limb wall 4c are connected.
Connected to the ends of the limb walls 4b, 4c remote from the web wall 4a are a first connection wall 4d and a second connection wall 4e, both directed horizontally inwardly, such that a downwardly-directed slot-shaped opening 4k is formed along the rail 4 between the connection walls 4d, 4e. The web wall 4a accommodates the fifth current conductor 5e on the inner side, the first limb wall 4b accommodates the second and third current conductors 5b, 5c on the inner side and the second limb wall 4c accommodates the first and fourth current conductors 5a, 5d on the inner side. The inner sides of the web wall 4a and the connection walls 4d, 4e are used as horizontal running surfaces 4f to 4i for wheel sets 7a, 8a of the current collector carriage la. Shown in particular are the first running surface 4f on the first connection wall 4d and the second running surface 4g on the second connection wall 4e for the lower, first wheel sets 7a, via which the current collector carriage la is displaced in the rail 4, and the third and fourth running surfaces 4h, 4i on the web wall 4a for the upper, second wheel sets 8a, via which the current collector carriage la is guided in the rail 4.
It can also be seen that the current conductors 5a to 5e are held in clamp-like undercuts 41. Adjoining the current conductors 5a to 5e are the contact means 6a to 6e for transferring current and/or control signals between the current conductors 5a to 5e and the current collector carriage la. The contact means 6a to 6e are resiliently mounted in the direction of the current conductors 5a to 5e in pockets 3f to 3j (see also Figures 3 and 4) of the body 3 of the current collector carriage la.
It is also shown that a part of the body 3 referred to as the support 3a protrudes downwards from the rail 4 between the walls 4d, 4e and is connected to the electrical line 12 (see Figure 1) and the housing 14.
Figure 3 shows a perspective view of the current collector carriage la of Figure 1 having the travelling mechanisms 2a, 2b which are releasably connected to the body 3 of the current collector carriage la at the front and rear as seen in the displacement direction V.
The current collector carriage la is supported by the two travelling mechanisms 2a, 2b and can be displaced thereby along the current-carrying rail 4. The body 3 includes the flat support 3a having an upper, first end 3b and a lower, second end 3c, on which a first and a second thin-walled supporting wall 3d, 3e are arranged laterally, i.e., in the displacement direction V, such that a T-shaped design of the body 3 is produced. The supporting walls 3d, 3e extend in opposite directions directed away from the support 3a in each case in one of the displacement directions V. Disposed on the body 3 are the five pockets 3f to 3j which are each formed in the shape of a container and cuboid, are open on one side and are used to receive the contact means 6a to 6e. The first supporting wall 3d has the first pocket 3f passing through it at the bottom and the second pocket 3g passing through it at the top and the second supporting wall 3e has the third pocket 3h passing through it at the bottom and the fourth pocket 3i passing through it at the top.
The openings of the first and second pockets 3f, 3g and of the third and fourth pockets 3h, 3i each point in mutually opposite horizontal directions transverse to the displacement directions V, wherein at the same time the openings of the upper second and fourth pockets 3g, 3i and the openings of the lower first and third pockets 3f, 3h each point in mutually opposite directions. Disposed on the first end 3b of the support 3a between the supporting walls 3d, 3e is the upwardly-opened fifth pocket 3j.
Receiving connecting means in the form of a first and a second sleeve 3k, 31 are disposed in each case on a vertical edge of the supporting walls 3d, 3e pointing away from the support 3a - and thus at the front and rear on the current collector carriage la. The sleeves 3k, 31 are identical in construction having a circular cross-section and are formed in a hollow-cylindrical manner with an inner bore. In the case of a current collector carriage la in a horizontally extending rail 4, the inner bores are aligned vertically with respect to their longitudinal extension. The sleeves 3k, 31 also each have a lower, first edge 3m and an upper, second edge 3n (see Figure 4). Each sleeve 3k, 31 is supported in the transition region between the sleeves 3k, 31 and the supporting wall 3d, 3e by a reinforcement 3t. The mutually opposite end sides, pointing in opposite vertical longitudinal directions of the sleeves 3k, 31, are open.
The first travelling mechanism 2a is attached to the first sleeve 3k and the second travelling mechanism 2b is attached to the second sleeve 31. The travelling mechanisms 2a, 2b are identical in construction and each comprise a vertical and wall-like supporting body 9 (see Figures 5a and 5b) in which a lower, first wheel set 7a having two lower running wheels 7b, 7c and an upper, second wheel set 8a having two upper guide wheels 8b, 8c are accommodated in a rotatably-mounted manner. A cylindrical first pin 10b, not illustrated, (see Figures 5a and 5b) is attached to the supporting body 9 as a rigidly formed connecting means to be received. Disposed between the first and second guide wheels 8b, 8c is a flat, plate-shaped tongue 17 which is used as an entrance aid when entering a funnel-shaped region of the rail 4. Of course, the travelling mechanisms 2a, 2b can also operate without a tongue 17 of this type. The design of the travelling mechanisms 2a, 2b is illustrated in detail in Figures 5a and 5b. The outer diameter of the pin 10b is smaller than the inner diameter of the sleeve 3k, 31. The pin 10b is slid into the sleeve 3k, 31 from the lower, first edge 3m until the supporting body 9, which protrudes outwards through a vertical, slot-shaped cut-out 3o provided in the sleeve 3k, 31 and is guided through the cut-out 3o, abuts with an upper edge against a third edge 3q (see Figure 4) and the body 3 is thus supported on the supporting body 9 via the edge 3q. The travelling mechanisms 2a, 2b are connected in this manner in a positive-locking manner to the current collector carriage la at least in one embodiment. The supporting body 9 and thus the travelling mechanisms 2a, 2b are disposed on the body 3 in an articulated manner and can be pivoted in a hinge-like manner about a vertical axis A
within an angle a (see Figure 4) dependent upon a width B (see Figure 4) of the cut-out 3o and the dimensions of the supporting body 9. In other words, the pivotability of the travelling mechanisms 2a, 2b is limited by the geometric configuration of the cut-out 3o.
The axis A is embodied by the pin 10b or a vertical central axis of the pin 10b and coincides with a central axis of the sleeve 3k, 31.
However, the axis A does not have to coincide concentrically with the central axes of the receiving connecting means and the connecting means to be received or of the sleeve 3k, 31 and of the pin 10b. It is also possible that the axis A extends through one of the connecting means but is located eccentrically with respect to any central axes of the connecting means. In the case of a reconfigured cut-out 3o, the pin 10b can be slid into the sleeve 3k, 31 starting from the upper, second edge 3n. It is also possible to provide a pivoting mechanism whose hinged movement is actively achieved in a positive-locking or non-positive-locking manner in another way - without a supporting body 9 protruding through a cut-out 3o. Of course, it is also possible to dispose the sleeves 3k, 31 on the travelling mechanism-side and in each case to dispose a supporting body 9 with a pin 10b on the body 3.
On a side of the travelling mechanism 2a, 2b opposite the wheel sets 7a, 8a, a second groove 3u extending in the longitudinal direction of the pin 10b and being disposed radially with respect to the axis A can be provided on the pin 10b in a second embodiment (see Figure 5b). As seen in this radial direction, the cross-section of the second groove 3u, starting from the peripheral surface, has a funnel-shaped region extending into the interior of the pin 10b, which region is adjoined by a rectangular cross-sectional region (see Figure 5b). When the travelling mechanism 2a, 2b is connected to the body 3 and is not pivoted-out, the second groove 3u is disposed opposite a first groove 3p which is provided in the sleeve 3k, 31, also extends vertically and has a rectangular cross-section. An elongate and cuboid restoring element 18 having a cross-section formed in a complementary manner with respect to the first groove 3p can be slid into the first groove 3p and protrudes into the interior of the sleeve 3k, 31 in a web-like manner in the radial direction. The restoring element 18 consists of a resiliently deformable material, e.g., a rubber material. When the body 3 and the travelling mechanism 2a, 2b are brought together, the restoring element 18 attached in the second groove 3u is connected to the first groove 3p of the sleeve 3k, 31in a positive-locking manner. Owing to the co-operation of the restoring element 18 with the first groove 3p, a resiliently pivotable positioning of the travelling mechanisms 2a, 2b is permitted. The restoring element 18 assumes in particular a restoring function, whereby the deflection of the travelling mechanisms 2a, 2b about the angle a set during travel on a curve is automatically cancelled during travel in a straight line. In other words, owing to the described arrangement of the restoring element 18, the travel of the first current collector carriage la in a straight line is fixed as a state of equilibrium in which the restoring element 18 is in a non-loaded state which is automatically set as soon as travel on a curve ends and the occurring outer force application upon the restoring element 18 is cancelled.
Therefore, the travelling mechanisms 2a, 2b are automatically aligned in the displacement direction V by the restoring force of the spring element 18. The elastically-resilient restoring effect or inner restoring force of the restoring element 18 can be varied e.g., by the selection of different materials having correspondingly different material characteristics or by adapting the geometric dimensions, in particular the length of the restoring element 18.
Additionally provided on the support 3a on two sides pointing transversely with respect to the displacement directions V are two horizontal bearing plates 3r, 3s which are identical in construction and are spaced apart from each other in parallel and between which in each case a horizontal, third, lateral guide wheel 11 is accommodated in a rotatably mounted manner.
The contact means 6a to 6e of the current collector carriage la are connected in a conductive manner in each case to a first end, not illustrated, of a current cable. All of the current cables are consolidated in the electrical line 12 which is connected to the system to be supplied with current. The electrical line 12 is connected to the current collector carriage la via a connection part 13 (see Figure 4) located on the lower, second end 3c. The connection point is surrounded by the housing 14.
Figure 4 illustrates a perspective view of the body 3 without the travelling mechanisms 2a, 2b, 2c. The support 3a, the supporting walls 3d, 3e adjoining the support and the pockets 3f to 3j disposed on the supporting walls 3d, 3e, in particular the openings of the pockets 3f, 3i, 3j can clearly be seen in particular.
In addition, the vertical, slot-shaped cut-out 3o having the minimum width B
is provided in a sleeve wall of the sleeve 3k, 31. The cut-out 3o is arranged such that it points away from the support 3a in one of the displacement directions V, beginning at the horizontal, lower, first edge 3m, interrupts the latter whilst extending upwards and is delimited at the top by the central, likewise horizontal, third edge 3q which is offset in parallel with the first edge 3m. The vertically extending first groove 3p having a rectangular cross-section is provided in the interior of the sleeves 3k, 31 and is disposed opposite the cut-out 3o and extends in a plane with the supporting wall 3d, 3e.
The cut-out 3o in the sleeve 3k, 31 has a height H which is a result of the distance of the lower, first edge 3m from the central, third edge 3q, which means that a closed and regular peripheral surface remains only above the cut-out 3o between the central, third edge 3q and the upper, second edge 3n. The angle a is formed by a notional line, which extends in a plane with the supporting walls 3d, 3e and intersects the axis A, and an inner side of the cut-out 3o of the sleeve 3k, 31. The decisive feature is the width B (see also Figure 6) of the inner side as the minimum horizontal dimension of the cut-out 3o.
It is also possible that the cut-out 3o extends in a continuous manner in the vertical direction, also interrupts the second edge 3n and does not produce a third edge 3q. The vertically divided peripheral surface of the sleeve 3k, 31 thus forms two resilient latch arms which permit accommodation of the pin 10b e.g., in the form of a snap-fit connection or clip-connection by positive-locking or non-positive-locking assembly in one of the displacement directions V. The downwardly directed connection part 13 on the second end 3c of the support 3 is also illustrated.
Figure 5a shows the first and second travelling mechanism 2a, 2b having the wheel sets 7a, 8a which are each connected to the supporting body 9 lying one above the other. The pin 10b, which is vertically aligned in its longitudinal extension, is disposed on a vertical side of the supporting body 9 spaced apart from the wheel sets 7a, 8a.
Figure 5b illustrates a partial view of the connection between the first/second travelling mechanism 2a, 2b in the third embodiment having the body 3 in a pivoted-out position.
The restoring element 18 is particularly shown and is disposed in the first groove 3p of the sleeve 3k, 31 and is simultaneously accommodated by the second groove 3u of the pin 10b. Furthermore, it can be seen that the restoring element 18 is deformed owing to a deflection or rotation of the pin 10b with respect to the sleeve 3k, 31 or about the axis A
and by the angle a.
Figure 6 shows the first current collector carriage la having a first travelling mechanism 2a and a second current collector carriage lb having a second travelling mechanism 2b.
The current collector carriages la, lb can be displaced on a curved track K
and are coupled together via a third travelling mechanism 2c. The third travelling mechanism 2c includes - in a similar manner to the supporting body 9 of the travelling mechanisms 2a, 2b - a wall-like connecting web 9a. The shape of the connecting web 9a resembles two assembled supporting bodies 9 forming a vertical axis of symmetry. Disposed on two ends of the connecting web 9a facing away from each other are in each case the first pin 10b and a second pin 10c which are vertically aligned with respect to their longitudinal extension. The connecting web 9a accommodates, between the pins 10b, 10c and along the axis of symmetry, two wheel sets 7a, 8a so that these are rotatably mounted one above the other. In order to connect the two current collector carriages la, lb together, the pin 10b is slid into the sleeve 31 of the first current collector carriage la and the pin 10c is slid into the sleeve 3k of the second current collector carriage lb. The pins 10b, 10c are identical in construction to the first embodiment, and thus comprise a regular peripheral surface. There is thus no positive-locking connection between the pins 10b, 10c and the first groove 3p, whereby the travelling mechanism 2c can be pivoted with respect to the current collector carriages la, lb within the angle a (see also Figure 7). Of course - in a similar manner to the configuration of the travelling mechanisms 2a, 2b - it is also possible to provide the pins 10b, 10c in each case with a second groove 3u and a restoring element 18 in order to permit an elastically-resilient pivotability of the travelling mechanism 2c with respect to the current collector carriages la, lb.
Figure 7 shows a view of the current collector carriages la, lb coupled via the pins 10b, 10c of the third travelling mechanism 2c. The connecting web 9a of the travelling mechanism 2c without the wheel sets 7a, 7b is shown in a position pivoted-out with respect to the supporting walls 3d, 3e. In addition, the axis A illustrated as a dot and the width B of the cut-out 3o are identified. At the maximum possible deflection with the angle a, the connecting web 9a adjoins one of the inner sides of the cut-out 3o of the sleeve 31. A similar situation occurs for the angle ratios on the sleeve 3k between the connecting web 9a and the first supporting wall 3d of the second current collector carriage lb.
The variable setting of elastically-resilient and non-resilient pivotability of the travelling mechanisms 2a, 2b, 2c with respect to the body 3 is preferably produced by an application-specific exchange or use of travelling mechanisms 2a, 2b, 2c formed in a correspondingly modular manner. In other words, the corresponding type of pivotability is thus produced by the described connections between two intrinsically rigid connecting means - e.g., between the pins 10b, 10c slid into the sleeves 3k, 31 and rotatable therein and having the second groove 3u for the restoring element 18 provided thereon.
In addition to the substantially horizontal alignment described above, the mutually opposite displacement directions V can of course be aligned to be non-horizontal and thus form different degrees of inclination.
Also, the travelling mechanisms 2a, 2b, 2c can be connected to the body 3 not only by a relative movement of the travelling mechanisms 2a, 2b, 2c and of the body 3 in parallel with the axis A but also transversely with respect to the axis A.
