P139717NLOO
Current collecting assembly for mobile installations
BACKGROUND
The invention relates to a current collecting assembly for mobile installations, such as travelling bridge cranes, comprising a carriage and a current conducting rail.
Such a current collecting assembly 1s known, wherein the known current collecting assembly comprises a current conducting rail with a substantially U-shaped rail profile defining a conductor space and a current conductor arranged within the conductor space. The known current collecting assembly further comprises a carriage configured for moving along the current conducting rail in a movement direction and comprising a current collecting brush, such as a carbon brush, configured for being inserted into the conductor space and for contacting the current conductor to collect electrical energy.
SUMMARY OF THE INVENTION
The known current collecting assembly, for example, is used in an environment where multiple travelling bridge cranes are present and moving simultaneously, wherein each of the travelling bridge cranes is provided with a current collecting assembly. A disadvantage of the known current collecting assembly is that the current position of the travelling bridges cranes is unknown to the controller, and, therefore, it is very difficult to control the travelling bridge cranes as every command has to take all present travelling bridge cranes into account.
It is an object of the present invention to ameliorate or to eliminate one or more disadvantages of the known prior art, to provide an improved current collecting assembly or to at least provide an alternative current collecting assembly.
According to a first aspect, the invention provides a current collecting assembly for mobile installations, such as travelling bridge cranes, comprising a carriage and a current conducting rail, wherein the current conducting rail comprises a substantially U-shaped rail profile defining a conductor space and a current conductor arranged within the conductor space; and the carriage is configured for moving along and partially within the current conducting rail in a movement direction and, optionally, comprises a current collecting brush, such as a carbon brush, configured for being inserted into the conductor space and for contacting the current conductor to collect electrical energy, wherein the current collecting assembly comprises a position determining device with a position determining strip arranged within the conductor space, and a position determining sensor arranged at the carriage, wherein the position determining strip and the position determining sensor are configured for cooperating in order to determine the position of the carriage with respect to the current conducting rail.
During use, the carriage is connected to a mobile installation, such as a travelling bridge crane with the concrete industry, in order to provide optionally current to the travelling bridge crane. The position determining strip and the position determining sensor cooperate in order to determine the position of the carriage with respect to the current conducting rail. As a result, a controller, which may be a person or a software system, is aware of the current location of the carriage and, thus, the travelling bridge crane to which the carriage is connected. In particular the position of the travelling bridge crane is known in all cases and/or may be followed real-time. Since the position of the travelling bridge crane is known to the controller, controlling the travelling bridge cranes has become simplified in comparison to the known current collecting assembly.
Additionally, since the position determining strip and, therefore, the position determining sensor are arranged within the conductor space defined by the U-shaped rail profile, the risk of contaminants, such as moisture and dust, contaminating the position determining strip and/or the position determining sensor is reduced or in the ideal case eliminated.
Furthermore, since the position determining device is integrated into the current collecting assembly, a compact and robust combination of electrical power supply and position determination for mobile installations may be obtained.
In an embodiment, the U-shaped rail profile comprises a profile bottom, a first profile leg standing substantially perpendicular to the profile bottom, and a second profile leg standing substantially perpendicular to the profile bottom. In an embodiment thereof, each of the first and second profile leg has a leg extension provided at the end thereof facing away from the profile bottom, wherein the leg extension of the first profile leg extends towards the leg extension of the second profile leg, and vice versa, such that a passage for the carriage is provided between the leg extensions.
In an embodiment, the position determining strip comprises a strip-shaped carrier, and a magnet tape arranged at the strip-shaped carrier. Preferably, the strip-shaped carrier has a first height, and the magnet tape has a second height, wherein the second height is smaller than the first height. In a preferred embodiment thereof, the magnet tape 1s an absolute or incremental coded magnetic tape. By providing a magnet tape onto a strip-shaped carrier, the position determining strip may be more firmly in comparison with only the magnet tape.
Furthermore, the strip-shaped carrier may be used for installing the position determining strip into the current conducting rail without blocking a part of the magnet tape, such that the whole surface of the magnet tape may be used for determining the position of the carriage.
Additionally, since the magnet tape may be an absolute or incremental coded magnetic tape, it is possible to determine the absolute position of the carriage. This is advantageous, since even after a power failure the position of the carriage with respect to the current conducting rail is still known.
In an embodiment, the current conducting rail comprises a position determining strip retainer provided at the inner surface thereof. In an embodiment thereof, the position determining strip retainer has a first strip retainer portion and a second strip retainer portion, wherein the first and second strip retainer portions together define an opening for allowing the position determining strip to be sensed by means of the position determining sensor. An advantage of this embodiment is that the position determining strip may be held firmly within the current conducting rail, while the magnet tape is still accessible in order to be sensed by the position determining sensor.
In an exemplary embodiment, the first strip retainer portion is shaped like an elbow, and the second strip retainer portion comprises a first retainer portion part arranged at the inner surface of the profile bottom and extending substantially perpendicular therefrom, and a second retainer portion part arranged at the end of the first retainer portion part facing away from the profile bottom, wherein the first retainer portion part is thicker than the second retainer portion part in order to form a receiving recess within the second strip retainer portion.
In an embodiment, the position determining strip retainer includes one or more supports arranged at the inner surface of the U-shaped rail profile and between the 5 first and second strip retainer portions, and configured for supporting the position determining strip retained within the position determining strip retainer. During use, when the position determining sensor passes along the position determining strip, the position determining sensor may push against the position determining strip resulting in the position determining strip moving away from the position determining sensor. By providing one or more supports at the inner surface of the U-shaped profile, the position determining strip is supported by the supports and advantageously prevented from moving away from the position determining sensor.
In an embodiment, the position determining sensor comprises a Hall sensor.
In an embodiment, when each of the first and second profile leg has a leg extension provided at the end thereof facing away from the profile bottom, wherein the leg extension of the first profile leg extends towards the leg extension of the second profile leg, and vice versa, such that a passage for the carriage is provided between the leg extensions, the current conducting rail comprises one or more flexible sealing strips configured for sealing the passage for the carriage provided between the leg extensions. By providing one or more flexible sealing strips for sealing the passage for the carriage, contaminants, such as dust and moisture, are advantageously prevented from entering the conductor space defined within the current conducting rail.
In an embodiment, the position determining strip and the position determining sensor are configured for cooperating in order to determine the absclute position of the carriage with respect to the current conducting rail.
In an embodiment, the current conductor is substantially strip-shaped. Preferably the current conductor is a copper strip.
In an embodiment, the current collecting assembly comprises an inserting device configured for inserting the position determining strip into the current conducting rail.
In an embodiment, the inserting device comprises a pulling block configured for being inserted into the conductor space of the U-shaped rail profile, wherein the pulling block at the leading end thereof is provided with a leading connector, to which a pulling rope is connected, and at the trailing end thereof is provided with a trailing connector, to which an inserting cable is connected, wherein the inserting device further comprises an inserting block configured for pulling the position determining strip into the U-shaped rail profile. In an embodiment thereof, when the position determining strip retainer includes one or more supports arranged at the inner surface of the U- shaped rail profile and between the first and second strip retainer portions, and configured {for supporting the position determining strip retained within the position determining strip retainer, the inserting block is configured to move within the position determining strip retainer and to be guided by the position determining strip retainer. During inserting the position determining strip into the current conducting rail, the user of the inserting device may simply grab the pulling rope and walk along the current conducting rail while holding the pulling rope in order to insert the position determining strip into the current conducting rail. This is advantageous, as the position determining strip is insertable into the current conducting rail relatively simple, without having to touch the position determining strip during insertion thereof.
In an embodiment, the inserting block has an elongated block body of which the height corresponds to a distance between two supporting projections of the position determining strip retainer, and the block body is provided
: with a securing slit for securing the position determining strip to the inserting block, wherein the securing slit extends substantially parallel to the longitudinal direction of the block body, and is located such that the position determining strip is placed on top of the two supporting projections. In an embodiment thereof, the block body is provided with a securement, such as a pin opening and a securing pin inserted therein, for securing the position determining strip to the block body. In a preferred embodiment thereof, the inserting block further includes one or more guiding members arranged at the block body in order to guide the inserting block through the position determining slit retainer. In an embodiment thereof, the inserting block comprises guiding members arranged at the top and bottom side of the block body, wherein each of the guiding members is provided with a first guiding portion arranged in line with the securing slit, and a second guiding portion arranged on a side of the first guiding portion facing away from the block body, wherein the second guiding portion is offset to the first guiding portion, wherein when the inserting block is inserted into the current conducting rail, the upper second guiding portion is arranged next to one of the two supporting projections, and the lower second guiding portion is arranged next to the other one of the two supporting projections and both of the first guiding portion are arranged within the opening defined by the first and second retainer portions. Due to the guiding members at the block body of the insert block, the insert block is retained within the position determining strip reliable. This is advantageous, since the inserting block is prevented from exiting the position determining strip retainer, while inserting the position determining strip into the position determining strip retainer.

Both the first retaining portion 17 and the second retaining portion 18 are extending from the inner surface of the profile 4 into the conductor space 5. The first retaining portion 17, the second retaining portion 18 and a part of the profile 4 located therebetween together define a retaining space 19, in which a non-shown current conductor, such as a copper strip, and/or a non-shown data conductor may be arranged.
Furthermore, as shown in figures 1 and 2, the U- shaped rail profile 4 includes a first flexible sealing strip 20 and a second sealing strip 21 arranged at opposite sides of the passage 15 for the carriage 3 and extending from the U-shaped rail profile 4. Each of the first and second flexible sealing strips 20, 21 has a curved sealing body 22, and a securing portion 23, for example anchor- shaped, configured to be received within a securing chamber 24 provided at each of the leg extensions 13, 14, in particular at the side facing away from the conductor space. As shown in figure 2, the ends of the curved sealing bodies 22, which are facing away from the leg extensions 13, 14, are abutting against each other, such that the passage 15 for the carriage 3 is closed off by means of the first and second flexible sealing strips 21, 22.
The U-shaped rail profile 4 has a blocking nock 25 arranged at the inner surface of the profile bottom 10 and extending into the conductor space 5. The blocking nock 25 is configured for preventing the carriage 3 from being inserted incorrectly into the current conducting rail 2.
The carriage 3 is configured for being inserted at least partially into the conductor space 5 of the current conducting rail 2. The carriage 3 comprises a collector body 30 having a lower portion 31 configured for being located outside the conductor space 5, and an upper portion 32 configured for being located within the conductor space 5. The lower portion 31 is substantially sheet-shaped, such that it is enabled to pass through the first and second sealing strips 20, 21 arranged at the current conducting rail 2.
As shown in figure 1, the upper portion 32 of the collector body 30 is provided with a first set of wheels 33 configured for running over the conductor retainer 16 at the profile bottom 10, and a second set of wheels 34 configured for running over a part of the leg extensions 13, 14 of the current conducting rail 2. Furthermore, at the leading end and the trailing end, the upper portion 32 of the carriage 3 is provided with steering wheels 35 enabling the carriage 3 to corners arranged within the current conducting rail 2.
Although not shown, the carriage 3 may comprises a number of current collecting brushes, such as a carbon brushes, configured for contacting the one or more current conductors provided within the conductor space 5 of the current conducting rail 2. The non-shown current collecting brushes may be connected electrically to an umbilical cable 36 for feeding collected current to a non-shown mobile installation, such as a travelling bridge crane.
In order to determine the position, in particular the absolute position, of the carriage 3 within the current conducting rail 2, the current conducting rail 2 is provided with a position determining strip 40 and the carriage 3 is provided with a position determining sensor 60.
As shown in more detail in figure 3A, the position determining strip 40 comprises a strip-shaped carrier 41 having a first height, for example, of 20 mm, and a magnet tape 42 secured to the strip-shaped carrier 41 and having a second height, for example, of 10 mm. The magnet tape 42 may be absolute or incremental coded magnetic tape and may be written with an absolute or incremental track. An example of an absolute coding of the magnet tape 42 is shown in figure 3B, which absolute coding has an order of magnetic north and south poles. Optionally, the position determining strip 40 is provided with a through hole 43, for example, at the leading end thereof in order to be able to install the position determining strip 40 into the current conducting rail 2, as will be explained below.
In order to accommodate the position determining strip 40 within the conductor space 5, the current conducting rail 2 is provided with a position determining strip retainer 44 at the inner surface of the first and second profile leg 11, 12. The position determining strip retainer 44 has a first strip retainer portion 45, which is shaped like an elbow and extends from the inner surface of the respective profile leg 11, 12. Further, the position determining strip retainer 44 has a second strip retainer portion 46 with a first retainer portion part 47 arranged at the inner surface of the profile bottom 10 and extending substantially perpendicular therefrom, and a second retainer portion part 48 arranged at the end of the first retainer portion part 47 {facing away from the profile bottom 10. The first retainer portion part 47 is thicker than the second retainer portion part 48 in order to form a receiving recess within the second strip retainer portion 44. The first and second retainer portions 45, 46 together define an opening B for allowing the position determining strip 40 to be sensed.
As shown in figure 2, the position determining strip retainer 44 is provided with two supporting projections 49, which are arranged at the inner surface of the respective leg 11, 12 and between the first and second strip retainer portions 45, 46. The two supporting projections 49 project into the conductor space 5 in order to support the position determining strip 40 arranged within the position determining strip retainer 44. The position determining strip 40, therewith, is maintained in its position when the carriage 3 moves along the position determining strip 40.
As mentioned above, the carriage 3 is provided with a position determining sensor 60. The position determining sensor, for example, may be equipped with a
Hall sensor configured for sensing the coding of the absolute coded magnet tape 42. The position determining sensor 60 is in data communication with a non-shown controller via the umbilical cable 36. During use, the position determining sensor 60 is moved along the magnet tape 42 by means of the carriage 3. While moving along the magnet tape 42, the position determining sensor 60 senses the order of the north and south poles of the magnet tape
42 and subsequently provides an absolute value indicative for the position of the carriage 2.
In order to be able to determine the absolute position of the carriage 3 within the current conducting rail 2, a reference point, at which the absolute position is 0, has to be determined at the first use of the current collecting assembly.
The Applicant further has invented an inserting device 70 for inserting the position determining strip 40 within a position determining strip retainer 44. The inserting device 70 comprises a pulling block 71 configured to be inserted into the conductor space 5 of the current conducting rail 2. At the leading end, the pulling block 71 has a leading connector 72, such as a screw eye, to which a pulling rope 73 is connected. The pulling rope 73 is hanging downwards from the pulling block 71 and out of the conductor space 5, such that a user may be enabled to grab the pulling rope 72 in order to pull the pulling block 71 through the conductor space 5.
At the trailing end, the pulling block 71 is provided with a trailing connector 74, such as a screw eye, to which an inserting cable 75, such as a steel wire, is connected. The inserting cable 75 in its turn is connected to an inserting block 76 that is configured for pulling the position determining strip 40 into the position determining strip retainer 44.
As shown in figure 4B, the inserting block 76 has an elongated block body 77 of which the height corresponds to the distance between the two supporting projections 49 of the position determining strip retainer 44, such that the block body is enabled to move between the two supporting projections 49. The block body 77 is provided with a securing slit 78 for securing the position determining strip 40 to the inserting block 76. The securing slit 78 extends substantially parallel to the longitudinal direction of the block body 77, and is located such that the position determining strip 40 is placed on top of the two supporting projections 49. In other words, the height of the supporting projections 49 substantially corresponds to the width of a part of the block body 77 located between the securing slit 78 and an abutment side A of the block body 77 abutting against the inner surface of the respective leg 11, 12 when the inserting block 76 is inserted into the current conducting rail 2. In order to secure the position determining strip 40 to the inserting block 76, the block body 77 is provided with a pin opening 79 extending substantially perpendicular to the securing slit 78. A securing pin 80 may be inserted into the pin opening 79 in order to secure the position determining strip 40 to the inserting block 76. The block body 77 further includes a securing through hole 81 for securing the inserting cable 75 to the inserting block 76.
The inserting block 76 further includes guiding members 82 arranged at the upper and lower side of the block body 77. Each of the guiding members 82 is provided with a first guiding portion 83 arranged in line with the securing slit 78, and a second guiding portion 84 arranged on a side of the first guiding portion 83 facing away from the block body 77. The second guiding portion 84 is offset to the first guiding portion 83 towards the abutment side A of the block body 77. When the inserting block 76 is inserted into the current conducting rail 2, the upper second guiding portion 84 is arranged above the upper one of the two supporting projections 49, and the lower second guiding portion 84 is arranged below the lower one of the two supporting projections 49, Both of the first guiding portions 83 are arranged within the opening B defined the first and second retainer portions 45, 46.
Each of the first and second guiding portions 83, 84 has tapered ends 85 allowing the inserting block 76 to be inserted into the position determining strip retainer 44 relatively easily.
During use, a user pulls the pulling rope 73, therewith pulling the pulling block 71, the inserting block
76 and thus the position determining strip 40 through the current conducting rail 2.
It is to be understood that the above description is included to illustrate the operation of the preferred embodiments and is not meant to limit the scope of the invention. From the above discussion, many variations will be apparent to one skilled in the art that would yet be encompassed by the scope of the present invention.
