Description

The invention relates to a rail profile for crane monorail systems and slewing cranes with integrable energy chain.

A rail profile is often formed as a hollow chamber profile and has a plurality of functional elements, such as a track rail for a crane truck.

There are already known rail profiles for crane monorail systems and slewing cranes in the art. Such rail profiles are usually made of a rolled or folded hollow profile or of an extruded aluminum hollow section. These hollow profiles are suitable for receiving crane carriages movable.

On the basis of the well-known rail profiles, the crane monorail systems (short crane tracks) or swiveling crane carriers (swivel cranes) can be set up.

Crane tracks occur in the field of handling technology in suspended systems, as ceiling systems, the so-called overhead crane tracks or crane monorail systems and as swiveling crane girders, which are arranged suspended on vertical columns (so-called vertical column swivel cranes) on.

The crane rail profiles or Krahnfahrbahnen can be designed as single lanes with a carrier or as multiple lanes with two or more mutually parallel crane lanes.

In the case of a single carriageway, a crane running gear runs as a carriage or crane carriage with, for example, two, four, six or more rollers. Hoists, such as chain hoists or manipulators, which can be moved with the crane trolley to the crane rail profile are attached to the crane carriages.

With the support of the hoisting equipment (crane manipulators), it is therefore possible to transport production goods attached as payloads from A to B within the workshop on the crane girder rail profiles. Lighter goods, such as goods in transit weighing up to 250 kg, are normally moved manually ("by hand") by the production worker on the crane carrier rail. Larger weights above 250 kg up to 2 tons, however, are usually moved with an electric or pneumatic drive on the crane girder rail. For this purpose, the electric or pneumatic traction drive is flanged to the crane truck.

In the multiple lanes run several juxtaposed crane car. Two crane carriages in two crane rail profiles or raceways arranged parallel to each other take up a crane jumper here. The crane jumper itself consists of a crane girder rail profile.

In the crane jumper there are one or more crane carriages, to which in the case of multiple lanes usually the chain hoists or manipulators are appended. As a result of the construction of a multiple carriageway, production goods can thus be displaced both in a longitudinal direction, also in the X direction, and in a transverse direction oriented orthogonally to the longitudinal direction, which is referred to as the Y direction. The longitudinal direction is often referred to by the experts in the field of handling technology as X-crane track and the crane drive bridge as Y-crane track.

Chain hoists (cranes) and manipulators in most cases require energy that must be supplied to the individual chain hoists and manipulators in supply lines of the crane tracks or crane rail profiles. The energy to be supplied can be supplied in the form of electrical energy ("electricity") or / and compressed air ("air"). In rare cases, in addition or alternatively, a supply of vacuum lines may be provided.

Energy supply systems for crane rail profiles are already known in the prior art. The known systems are briefly described below and are in the Fig. 1 to Fig. 5 illustrated.

First, as a prior art, power lines for crane carriages in crane rail profiles 10 with support of additional line drag carriage 40 within the crane rail profile 10, in which the crane car is movable, out. The individual cable drag carriages 40 in this case have brackets 41 for portions of the power lines 32a, which are preferably to be opened in order to be able to remove the respective sections of the power line 32a. Examples of this type of power line 32a, 32b are in the Fig. 1 and Fig. 2 shown. In Fig. 1 a power line 32a for compressed air is shown in FIG Fig. 2 an energy line 32b for electrical energy shown. The mostly arranged in the crane rail profile 10 and actually not completely visible carriage 40 to which the individual sections of the power lines 32a, 32b are attached, are shown in dashed lines in the non-accessible areas within the crane girder rail profile 10. The power line 32a, 32b (compressed air or pneumatic line 32a or electric line 32b) is attached in sections with large loops 32a to the cable drag carriages 40 and freely suspended in the areas between the carriages 40. The individual loops The power line 32a may be suspended in a spiral manner on the line drag rollers 40, as shown in FIG Fig. 1 is shown. This type of suspension is particularly suitable for compressed air supply lines but also for vacuum lines or electrical supply lines. In addition, a folded 32b (concertina-style) suspension is possible in Fig. 2 illustrated by an electric cable through a ribbon cable.

A power line 32 suspended with cable drag carriage 40 within the crane rail profile 10 reduces the travel range for the crane truck for chain hoists or manipulators because in one direction the tow tow carriages 40 with the power line attached thereto reduce the travel of the crane truck pushed together. In addition, objects in the loops 32a or folds 32b of the power line 32 may catch, cause damage, and disable the cranes or manipulators.

In addition to the laying of the power line 32 by means of cable drag carriage in crane rail profile 10, there are in the prior art also power lines with spiral hose 32 for the power lines for compressed air 32c, which are guided on an additional so-called C-rail (wire rope construction) 50a, as it is from the Fig. 3 can be seen. Fig. 3 shows a crane rail profile 10 with a crane trolley 20, the power supply line 32 is formed on an additional C-rail 50a with a pull rope 51 as a spiral tube 32c. The traction cable 51 is usually a wire rope spanned between the two ends of the C-rail 50a to movably hold the spiral hose 32c along the C-rail 50a. Depending on the position of the crane trolley 20, the spiral 32c of the power line 32 is more or less pulled apart, analogous to a telephone cord of a conventional telephone set. In principle, the energy line 32 as a spiral tube 32c and C-rail 50a can also be adapted for the supply of electrical energy. The C-rail 50a is secured by brackets in the form of connecting webs 53 on the crane rail profile 10 or directly to a ceiling support.

The power line through a suspended on a C-rail 50a spiral tube 32c is extremely expensive and therefore expensive to purchase and installation. In addition, additional space in the vicinity of the crane rail profiles 10 is required and there are additional interference edges. In addition, due to the dead weight of the lateral C-rail 50, 50a, 50b and the spiral power line construction 32c arranged thereon, a non-negligible moment also arises on the crane rail profile 10 itself, for which reason counterweights have to be mounted or other no less expensive measures have to be carried out. In addition, there is a risk that transport goods or other objects caught in the spiral. Basically, the helical power line 32c is a functional malfunctioning solution because the tension of the helix exerts tensile forces and retracts a smooth-running crane truck.

Another technique of suspending a power line 32 for crane carriages 20 with support of a C-rail 50b is in FIG Fig. 4 shown. Here, the power line 34, which is shown here as a compressed air line, loop-shaped 32 d of carriage 52 (hose car), which are movable in the C-rail 50 b attached. The crane trolley 20 can thus be moved completely in its crane rail profile 10 without the carriage of the power line 34 restricting its travel. The attachment of the C-rail 50b on crane girder rail profile 10 via brackets 53 as in Fig. 4 An advantage of the leadership of the power line 34 on a C-rail 50b with carriage 52 relative to the in Fig. 3 shown helical suspension is that power line 34 can be guided with larger diameters and higher weights to the crane carriages 20.

Due to the mounting of an additional C-rail 50b, basically the same disadvantages arise as already mentioned in connection with FIG Fig. 3 discussed spiraled power line were discussed.

Another type of power line 32 for supplying compressed air is based on the Fig. 5 described. The energy supply 32 is guided here in a so-called energy chain 30, wherein the energy chain 30 is in turn supported in a guide channel 60 arranged externally laterally on the crane carrier rail profile 10. The guide trough 60 is also referred to in the technical field as trough 60, U-trough 60 or U-profile 60 (U-rail profile 60). In the energy chain 30 compressed air lines and lines for electrical energy can also be performed together. The energy chain 30 has a stationary 33 and a mobile end 34. While the power line 32 are fixedly connected to the supply lines at the stationary end, the mobile end is guided on a holding element 24 to the crane carriage 20. When the crane carriage 20 is moved back and forth in the crane girder rail profile 10, the mobile end 34 of the energy chain 30 runs along accordingly and the energy chain 30 is received or deposited within the guide channel 60 more or less depending on the running direction of the crane carriage 20. The stationary end 33 of the power line 32, however, remains stationary with the crane rail profile 10 is connected.

The disadvantages of an energy chain 30 guided in a guide channel 60 or U-profile 60 largely correspond to the abovementioned disadvantages for a spiral 32c power line guide 32 on a C-rail 50a or the guidance of the power line guide with carriage 52 in a C-rail 50b. However, that is Exercise of moments due to the tangential mounting of the guide channel 60 relative to the C-rail 50a, 50b reinforced because the guide channel 60 with energy chain 30 applies more weight than a C-rail 50a, 50b. Compared to the C-rail 50a, 50b, however, there are the advantages that in the energy chain 30 several power lines 32 are guided simultaneously and that in the energy chain 30 less likely objects can catch, since the energy chain 30 is largely protected by the guide channel 60. In addition, the individual power lines 32 are protected by the energy chain 30 itself.

The aforementioned rail profiles of FIGS. 1 to 5 in a known genus are hollow chamber profiles with internal road surface and offer the advantage that the treads of the road are largely protected against contamination and thus the smooth running of the crane car is not hindered by pollution or deteriorated.

Preferably, the running surfaces are provided in the width and the lateral guides with a few millimeters of play, so that the running behavior of the crane car is not blocked and hindered.

Together, these known rail profiles all that, compared to the inner track, the profile are designed as a T-slot profile for the suspensions.

The rigidity and thus the load-bearing capacity of the rail profile result from this mutually dependent conformity.

The asymmetric rail profile shape does not take on equal tensile and compressive stabilities, such as a double T-beam profile. Therefore, this rail profile form has disadvantages in terms of rigidity and load capacity.

In the aforementioned FIGS. 1 and 2 The energy supply lines with the carriages (40) for attaching and guiding a suspended energy supply, as already described, are moved in the inner carriageway in association with the crane carriages and thus shared.

This type considerably shortens the available rail travel due to the space requirement of the carriages (40) and makes it necessary to provide a longer rail track.

In the mentioned Figures 3 . 4 and 5 the energy supply lines are arranged laterally or parallel to the rail profile roadway, flanged either directly by means of additional holders and carrier systems on the rail profile or separately mounted with additional systems.

All these variants of FIGS. 1 to 5 in a known design with the disadvantages described are to be improved by the newly developed inventive system and thus replaced.

EP 1 506 934 A2 discloses a suspension crane track which comprises at least one crane track rail and a carriage guided on the crane track rail. The crane track rail consists of several sections of a hollow profile. An energy supply is provided entirely within the hollow profile and provides the drive of the carriage with energy.

In DE 199 05 336 A1 a workstation supply device is described. The workstation supply device has a rail with a carriage guided longitudinally thereon and a supply line. The supply line is a compressed air line, which is attached to the carriage via a compressed air extraction connection.

In FR 2 567 819 A1 discloses a plastic profile rail having a lower wider chamber and an upper narrow chamber. A load capacity for a crane truck including a payload attached thereto is not provided.

The object of the invention is therefore to provide a crane girder rail profile, which provides an integrated receptacle for power lines for crane carriages, which exerts no or only negligible tangential moments on the crane girder rail profile and at the same time does not unnecessarily shorten the available for the crane carriage travels. In addition, power lines should also be cost-effective and space-saving even with just laid ceiling height mountable and have no space-consuming interference to avoid accidents

This object is achieved by a rail profile, which is designed as a hollow profile of a crane rail, according to claim 1.

Further advantageous rail profiles with lateral hollow chamber emerge from the subclaims 2 to 6.

This object is also achieved by a rail profile, which is designed as a hollow chamber profile of a crane rail, according to claim 7.

Another advantageous rail profile with hollow chamber profile results from the dependent claim. 8

The present task is also solved by a rail profile according to claim 9.

Further advantageous rail profiles with a central hollow chamber for receiving the energy chain emerge from the subclaims 10 and 11.

Yet another advantageous rail profile results from claim 13.

The given problem is solved by a rail profile with energy chain according to the subordinate claim 14.

Further advantageous rail profiles with energy chain emerge from the subclaims 15-17.

This problem is solved by a rail profile, which is designed as a hollow profile of a crane rail and a trained in a central cavity in a longitudinal direction guide for receiving a crane trolley, wherein the rail profile additionally comprises at least one receiving device for receiving at least one energy chain, wherein the at least one receiving device is integrated in the rail profile and extends in its longitudinal direction, wherein the at least one receiving device for receiving the energy chain is arranged laterally parallel to the central cavity with the guide for receiving the crane trolley.

A rail profile with at least one receiving device for receiving at least one energy chain, which can also be referred to as a rail profile with energy chain chamber, shows some advantages over conventional rail profiles. First, the rail profile with energy chain chamber can be installed to save space and compared to systems with additional rails or guide channels inexpensive to produce and install. Compared with systems with carriages in the rail profile of the crane trolley, there is the advantage of the travel paths within the rail profile that are completely available for the crane trolley. In addition, a rail profile with energy chain chamber also saves weight. Rail profiles with one or more energy chain chambers also allow the accommodation of the power lines, without these posing an accident risk due to hanging loops. In particular, the production transport traffic, such as forklift traffic, is not hindered and no power lines can be torn off, for example, by the lift mast of a forklift truck. This avoids accident causes and production losses. Furthermore, the leadership and freedom of movement of the crane truck is affected by the energy chain in any way, the leadership of the crane truck is usually designed as a track rail.

The energy chain arranged laterally to the travel area of the crane trolley is also advantageous if larger and less flexible power lines are to be guided to the crane trolley, as a result of which the energy chain to be used requires a larger bending radius. Energy chains with particularly large bending radii would result in an unprotected arrangement due to the large fault space to an increased risk of accidents, which is avoided by the protective side receiving device. A protective laterally arranged receiving device for the energy chain allows in particular larger bending radii of the energy chain as a centrally located receiving device above the crane trolley. In addition, a lateral receiving device may be provided on both sides of the track rail and the crane car in the central area adjacent to the track rail within the profile or the rail profile, so that several power lines can be divided into two energy chains. Receiving devices for energy chains on both sides of the rail profile are therefore particularly advantageous if the formation of a large bending radius over the entire height of the rail profile is required. Various Power lines or two or more receiving devices are advantageous if several and different types of energy, such as electrical energy or compressed air to be performed simultaneously to the crane car. In summary, the advantage of the lateral receiving device (s) is to be able to absorb energy chains with larger bending radii. This results primarily from the construction of the rail profile, since the energy chain in a lateral receiving device can extend over almost the entire height of the rail profile and in contrast to a central housing of the energy chain no portion and thus proportionate height for the crane car must be reserved and Therefore, a more optimal use of height of the rail profile results. Laterally arranged, molded and / or mounted receiving means for an energy chain also increase the rigidity of the entire rail profile and thus increase its carrying capacity.

Advantageously, a rail profile, in which the at least one laterally arranged receiving device for receiving the energy chain is formed as at least one further at least partially outwardly open chamber of the rail profile, which is parallel to the center of the receiving device for receiving the crane trolley with the guide for Receiving the crane trolley extends, wherein preferably two lateral receiving means for receiving the energy chain are provided in two further chambers, which are each arranged on one side of the central cavity receiving means for receiving the crane trolley and are arranged parallel to the guide for receiving the crane trolley.

A laterally mounted receiving device for receiving an energy chain allows either a larger bending radius of the inserted energy chain or a lower height of the rail profile or a combination of lower height and larger maximum bending radius of the energy chain, each adapted to the specific site.

The object is also achieved by a rail profile in which the at least one laterally arranged receiving device for receiving the energy chain as at least one further at least partially open to the central cavity chamber of the rail profile is formed, which extends along the central cavity, preferably two lateral hollow chambers are provided as receiving means for receiving the energy chain, which are each arranged on one side of the central cavity in the longitudinal direction parallel to the central cavity

Side chambers open to the hollow chamber with the guidance of the crane trolley have the advantage that the energy chain is better protected than side chambers which are open laterally to the outside and that no parts can enter the energy chain. It can be provided that the at least one laterally arranged receiving device for receiving the energy chain are configured as two hollow chambers each arranged underneath the guides and open to the central hollow chamber, which extend in the longitudinal direction parallel to the receiving device, wherein the energy chain in an X direction in Depending on the position of the crane trolley, a part of the energy chain in a left side lower hollow chamber and in a right lateral lower chamber is receivable horizontally movable loop can be arranged.

A lying flat in the lower region of the rail profile energy chain requires no headband.

It can also be provided that in addition to the receiving device and above the receiving devices each have a further lateral hollow chamber is open, wherein preferably also an upper hollow chamber is provided above the central cavity.

Another advantage of a lying flat in the lower part of the rail energy chain is the release of existing side chambers for other applications, such as the accommodation of additional drives for additional supply lines for tools, for the transport of material trolleys or the installation of probes and scales.

It is also advantageous that the at least one laterally arranged along the cavity with the guide receiving device for receiving an energy chain is constructed double-walled and preferably provided a symmetrical construction, each with a left and right of the cavity with the guide arranged double-walled receiving device for receiving an energy chain is.

A double-walled construction of the laterally arranged receiving device for an energy chain allows an additional stiffening of the entire rail profile, this advantage being particularly clear when a symmetrical construction is provided, each with a receiving device for an energy chain left and right of the central cavity of the rail profile for receiving the crane trolley , In the case of a symmetrical design, the rail profile can be used largely without tangential moments.

It can also be provided a rail profile, which is designed as a hollow profile of a crane girder rail and one in a cavity in a longitudinal direction has trained guide for receiving a crane trolley, wherein the rail profile additionally comprises at least one receiving device for receiving at least one energy chain, wherein the at least one receiving device is integrated into the rail profile and extends in the longitudinal direction, wherein the at least one receiving device for receiving the energy chain is arranged above the cavity with the guide for receiving the crane trolley.

An arrangement of the energy chain in an upper hollow chamber or part of the energy chain above the rail profile is initially very compact, since the rail profile does not have to be constructed wider due to side chambers. If there are any side chambers, they will be free for other tasks. The limitation of a arranged in the upper region of the rail energy chain on a single segment of the rail profile is not detrimental in many applications, such as a Y-bridge or as a swing boom of a slewing crane, since the designs anyway provide usually only a segment of a one-piece rail profile.

It may also be provided a rail profile, wherein the energy chain is arranged in a longitudinally movable loop in the longitudinal direction, depending on the position of the crane carriage, a part of the energy chain above the receiving device and above the rail profile can be arranged and another part of the energy chain in the receiving device is receivable.

Compared to a complete placement of the energy chain in an upper cavity of the rail profile, there is the advantage of lower design-related minimum height of the rail profile. In addition to lower ceiling height requirements, weight and material are also saved.

The object is achieved by a rail profile, which is designed as a hollow chamber profile crane rail and has a plurality of hollow chambers, wherein the rail profile has a formed in a cavity in a longitudinal direction guide for receiving a crane trolley, wherein above the guide in a central recess of the rail profile a central receiving area is arranged for receiving the crane carriage, wherein the central receiving area is composed of a central lower receiving area and a central upper receiving area which widens the lower receiving area to the top, the central lower receiving area is provided for receiving the crane truck and wherein a Energy chain in the central lower receiving area and in the central upper receiving area is arrangeable, with the central upper Receiving area has a smaller width than the central lower receiving area and only receives the energy chain and is provided for their leadership.

A rail profile with a centrally arranged receiving device for receiving an energy chain, also has some advantages over conventional rail profiles. First, such a rail profile can be installed to save space and compared to systems with additional rails or guide channels inexpensive to produce and install and easier to maintain. Compared to systems with carriages for the energy chain in the rail profile of the crane trolley, there is the advantage of the travel paths within the rail profile that are completely available for the crane trolley. In addition, weight is also saved by a rail profile with a central receiving device for the energy chain. Rail profiles with a central receiving device for the energy chain also allows an arrangement of the power lines, without these posing an accident risk by hanging loops. In particular, the production transport traffic, such as forklift traffic, is not impeded and no power lines can be torn off by the forklift lift mast. This avoids accident causes and production losses. Furthermore, the guide for the crane carriage, which is usually designed as a track rail, affected by the energy chain in any way. An accommodation of the energy chain in a shared with the crane carriage cavity is space-saving and cost-cutting. The cavity is divided into areas of a receiving device for the energy chain, the energy chain chamber, on the one hand and the area with the leadership of the crane carriage on the other hand, but without having to show visible boundaries.

Particularly preferred is a rail profile in which the receiving device is arranged centrally or centrally in the cavity of the rail profile and in the gravity axis of the rail profile, wherein preferably arranged on the guide for receiving the crane trolley additionally at least one guide for receiving guide elements for guiding the energy chain is ..

By a central placement of the energy chain in a receiving area within the centrally disposed cavity of the rail profile a torque-free construction, that is, a design that makes do without balancing weights, allows.

A guide for receiving guide elements for guiding the energy chain allows the energy chain a largely frictionless running when moving the crane trolley. By almost completely reducing the friction between energy chain and rail profile, wear of the energy chain becomes practical locked out. In addition, less noise due to the sliding of the energy chain within the leadership of the rail profile.

Also particularly advantageous is a rail profile in which the guides for receiving guide elements are designed as a track rail and the guide elements are arranged on the energy chain, wherein the guide elements are preferably designed as rollers and / or slide strips.

Casters and wear strips are inexpensive and effective lubricants to largely preclude friction of the energy chain during the process of the crane trolley in the rail profile. If the guide elements are accordingly designed as rollers or sliding strips, in particular a guide which is designed as a track rail, in order to give the rollers or wear strips an adequate guidance and at the same time to keep the friction low.

The object is also achieved by a combined rail profile, in which both at least one lateral receiving device and a central receiving device are provided for receiving an energy chain combination of both embodiments solved, wherein the rail profile, which is designed as a hollow profile of a crane rail, one in a cavity in a longitudinal direction formed guide for receiving a crane trolley, wherein the rail profile additionally comprises at least one receiving device for receiving at least one energy chain, wherein the at least one receiving device is integrated into the rail profile and extending in the longitudinal direction, wherein the at least one receiving device for Receiving the energy chain is arranged laterally parallel to the cavity with the guide for receiving the crane trolley, the rail profile ausgebi as a hollow chamber profile of a crane rail Leden is and has a plurality of hollow chambers, wherein the rail profile has a formed in a cavity in a longitudinal direction guide for receiving a crane trolley, wherein above the guide in a central recess of the rail profile, a central receiving area for receiving the crane trolley is arranged, wherein the central receiving area is composed of a central lower receiving area and a central upper receiving area which widens the lower receiving area upwards, wherein the central lower receiving area is provided for receiving the crane truck and wherein an energy chain in the central lower receiving area and in the central upper receiving area is arrangeable and wherein the central upper receiving area has a smaller width than the central lower receiving area A combined rail profile allows the installation of several different power lines, which at least partially transport different types of energy, such as pneumatic air or electric power, in various receiving devices. Separate installation of power lines for each type of energy is often required due to safety regulations or / and preferred or required by companies.

Particularly advantageous is also a rail profile, in which the at least one receiving device for the energy chain (s) is integrally integrated in the rail profile, wherein preferably the rail profile is extruded in one piece.

A one-piece design of the rail profile with receiving device for the energy chain and the crane car on the one hand reduces the manufacturing and production costs of the rail profile, on the other hand, the stability of the rail profiles can be increased. Integrally extruded rail profiles not only have good stability, but are also relatively inexpensive to produce due to the manufacturing process in one step.

The underlying object is further achieved by a rail profile with energy chain, consisting of a rail profile and an energy chain, the energy chain is composed of chain links, each having a cavity for receiving energy or supply lines in the interior, the energy or Supply lines include one or more lines for electrical power, compressed air, vacuum and / or hydraulic oil.

With the help of an energy chain supply lines for electric power, compressed air, vacuum and / or hydraulic oil can be performed especially protected against kinking within the provided receiving devices of the rail profile.

Particularly preferred is a rail profile with energy chain in which the respective supply lines for electric power and / or compressed air and / or vacuum and / or hydraulic are divided into several individual lines and wherein preferably the individual lines are divided into two energy chains.

A division of the supply lines on two energy chains allows a better distribution of the mass of a rail profile with energy chain, so that occurring tangential moments are largely avoided.

Particularly preferred is also a rail profile with energy chain, in which the energy chain has a plurality of movable chain segments in the X direction, wherein the energy chain is arranged in a movable in the X direction, wherein the individual chain segments vertically upright, that is, in an xz plane arranged movable loop, are movable and wherein depending on the position of the crane carriage, a part of the energy chain in the upper region of the receiving device or above the receiving device and a further part of the energy chain in the lower region of the receiving device is receivable ,

In addition, a rail profile in which the energy chain has a plurality of chain segments movable in the X direction, wherein the energy chain can be arranged in an xy plane movable loop and depending on the position of the crane carriage, a part of the energy chain in a left side lower Hollow chamber and in a right side lower chamber is receivable.

Different orientations of the energy chain within the rail profile allow versatile arrangement possibilities of the energy chain (s) in the rail profile, whereby a great flexibility in the construction of the rail profiles is created and many boundary conditions such as ceiling height, space, weight and other functions of the rail profile, etc. can be considered.

The following detailed description of FIGS. 6 to 14 refers to embodiments of the rail profile for crane monorail and slewing cranes. In particular, the representations as sketches need not be to scale. Some parts may be schematized and / or exaggerated.

While the Figures 6-9 refer to an inventive rail profile of a first embodiment with running in the center energy chain is based on the Figures 10a-13a a second embodiment of the rail profile according to the invention illustrated, in which one or more energy chains are housed in integrated laterally arranged in the rail profile chambers. The FIGS. 10b-13b illustrate a third embodiment, which is based on the second embodiment, but the simple wall construction of the side walls is replaced by a two-walled hollow chamber construction. The FIG. 14 Finally, shows a further variant of the third embodiment of the invention, in which the lateral receiving elements for one or two energy chains are extended beyond the height of the central region of the rail profile and the suspension of the rail profile is carried out at approaches the side cheeks. The numerals in the range of 100 to 199 refer to the first embodiment of the invention and the reference numerals in the range between 200 and 299 refer to the second embodiment of the invention. The references in the area 300 to 399 serve to designate features or components of the third embodiment as well as their variant. Similarly, the reference numerals between 400 and 499 refer to the fourth and between 500 and 599 to the fifth embodiment of the invention. Functionally identical or partially identical features of the various embodiments each have reference numerals with the same second and third digits (one and ten digits), the hundred digits indicating the respective embodiments.

In FIG. 6 a rail profile 110 according to the first embodiment of the invention is shown. The preferably symmetrically constructed rail profile 110 consists of preferably two circular hollow chambers 112 on each of which a side wall 111 is arranged on both sides, wherein as shown a one-piece construction is preferred. The side walls 111 generally include further hollow chambers 113 for stiffening the rail profile 110. In the outer walls of the side walls 111 T-grooves 114 may be integrated for additional mounting options. Inside the rail profile 110 and below the circular hollow chambers 112 is a receiving device 116 for an energy chain (not in Fig. 6 shown) and / or a crane carriage (not in Fig. 6 shown). The receiving device 116 is composed of a lower energy chain receiving area 116a and the crane car and an upper receiving area 116b occupied only by the energy chain. The energy chain is guided as a large loop within the receiving device, while the lower part of the energy chain is pushed or pulled by the crane carriage in the receiving area 116a (depending on the direction of movement of the crane carriage) from the crane carriage, the upper part of the energy chain loop is in the upper receiving area 116b. The energy chain may comprise guide elements which are movably arranged in the guides 117 of the rail profile. The guide elements of the energy chain can be designed as slide rails and / or guide rollers. The crane car becomes preferably guided along the guide or track rail 115 in the rail profile 110.

The representation in FIG. 7 shows first all elements from the FIG. 6 , In addition, in this figure, the crane truck 120 and the energy chain 130 are shown. A conventional crane carriage 120 is composed of a crane carriage carrier body 123 and at least one crane truck axle 121 with rollers 122. The energy supply to the crane car is carried by the energy chain 130 which is secured by a bracket 124 on the crane car. In the illustrated embodiment, the crane trolley 120 additionally has a guide roller 125 which guides the crane trolley 120 horizontally between the side cheeks of the rail profile 110 and more precisely between the rail tracks 115 and the lower holes 118 along the rail profile 110 in order to avoid tilting or tilting. The energy chain 130 has a plurality of chain segments 132, wherein one or more energy lines extend within the chain segments. The power lines can lead, for example, compressed air, vacuum or electricity. On individual or all chain segments guide elements 131, such as slides or rollers can be arranged on both sides. Slide rails have the advantage that they can be integrally formed on the body of a chain segment.

The presentation of the FIG. 8 essentially corresponds to the FIG. 7 , where the representation of the FIG. 8 from the opposite direction to FIG. 7 is. In this figure is clearer than by means of FIG. 7 to recognize that some chain segments 132 of the energy chain 130 are arranged in front of the crane car 120 and thus are in the receiving area 116a.

The same item from the FIGS. 7 and 8th is in FIG. 9 shown in a perspective view. Based on Fig. 9 It can easily be seen that the energy chain 130 runs completely within the rail profile 110 and consequently no disruptive edges protrude from the rail profile or are fastened to the rail profile. Disturbing edges can cause accidents such as a hooking of a forklift lift mast and thus cause production losses. The one end of the energy chain 130 is fastened to the crane carriage via a holder 124. The individual chain links 132 of the energy chain 130 then adjoin the special retaining element 124. The energy chain 130 is movably arranged within the receiving device 116 and, depending on the position of the crane trolley 120, is present as a loop or more or less elongated within the rail profile 110. The crane trolley 120 is arranged to be movable within the receiving device 116 in the receiving region 116a and is as a rule passed through rollers 122 arranged on at least one crane truck axle 121 along the rail track 115 guided. An additional guide in horizontal alignment can be done by an optional guide roller 125 which is arranged to be movable within the lower recess of the rail profile 110 and additionally secures the crane trolley 120 against being tilted, tilted or caught.

In the FIG. 10a a rail profile 210 according to the second embodiment of the invention is shown. The -like in the Fig. 10a illustrated-preferably symmetrically constructed rail profile 210 consists of a centrally disposed hollow chamber 212, on both sides of each side cheek 211 is arranged, wherein as in Fig. 10a shown a one-piece construction is preferred. The side cheeks 211 typically include further hollow chambers 213 for stiffening the rail profile 210. In the outer walls of the side cheeks, T-slots 214 may be integrated for additional mounting options. Inside the rail profile 210 and below the circular hollow chamber, a receiving device 216 is provided for a crane truck. An energy chain is guided in one of the two lateral receiving areas or chambers 219. The crane carriage is preferably guided along the guide or track rail 215 in the rail section 210.

The Figures 11 a and 12a show the rail profile FIG. 10a viewed from one of the two ends of the rail profile 210 with crane trolley 220 and energy chain 230. The crane trolley 220 corresponds to the crane trolley FIG. 7 wherein the energy chain retainer 224 is adapted to an energy chain 230 not disposed in the same receptacle, and thus preferably configured as bracket 224 as shown, one end of which is attached to the crane carriage body 223 and the other end to the first chain segment 232 of the energy chain 230 ,

A perspective view of the rail profile 210 according to the second embodiment of the invention is the Fig. 13a refer to. Based on Fig. 13a It can be clearly seen that the energy chain 230 extends completely within the rail profile 210 in the direction of the left of the two lateral receiving areas 219 and consequently no interfering edges protrude from the rail profile 210 or are fastened to the rail profile 210. Disturbing edges can cause accidents such as a hooking of a forklift lift mast and thus cause production losses. The one end of the energy chain 230 is fastened to the crane carriage via a holder 224, which in the second embodiment is preferably as in FIG Fig. 13a illustrated as a bracket is designed to lead the supply or power lines from the energy chain 230 in the lateral receiving area 219 to the crane carriage 220 in the central receiving device 216. The individual chain links 232 of the energy chain 230 adjoin the retaining element 224 or the bracket at one end. The energy chain 230 is within the Receiving device 219 arranged movably and depending on the position of the crane trolley 220 as a loop or more or less elongated within the rail profile 210 before. The crane trolley 220 is arranged to be movable within the receiving device 216 and is generally guided along the track rail 215 by rollers 222 arranged on at least one crane truck axle 221. An additional guide in horizontal alignment can be carried out by an optional guide roller 225, which is arranged movable within the lower recess of the rail profile 210 and additionally secures the crane trolley against tilting, tilting or snagging.

In the FIGS. 10b . 11b . 12b and 13b the third embodiment of the invention is shown, wherein the single-walled projections of the receiving means 319 were replaced for the energy chain 330 by a double-walled hollow profile construction, which are also preferably integrally formed in the rail profile 310 as shown in the figures. All other components correspond to the second embodiment of the invention and have already been among the FIGS. 10a . 11a . 12a and Fig. Illustrates. The figures with the name a and b, such as 10a and 10b, respectively correspond to each other. In the side cheeks of the lateral receiving areas 311b ribs 311c may be arranged for additional stiffening. The third embodiment preferably provides receiving areas 319 for an energy chain on both sides of the rail profile 310 and thus corresponds to a symmetrical design. This embodiment has the advantage of additional stability due to stiffening of the entire rail profile 310.

A rail profile according to the sixth embodiment is in the Fig. 13c shown. The presentation essentially corresponds to the Fig. 13b , wherein the side chambers or receiving areas for an energy chain 619 are not open to the side to the outside, but are open to the central hollow chamber. An advantage of this embodiment is that the energy chain 630 is particularly protected and the susceptibility is reduced, since not inadvertently materials can be introduced into the inwardly open side chambers 619, as is basically possible with at least partially outwardly open side chambers. In return, it is more expensive to insert the energy chain 630 into a still open side chamber 619. At the in Fig. 13c shown rail profile 610, the central hollow chamber 612 is not round but cuboid shown. Above the hollow chamber 612 a plurality of further hollow chambers 613 are provided, one of which is constructed as a larger T-slot 614 for the suspensions of the suspension. Further T-slots 614 are located at the top of the rail profile 610. Below the hollow chamber 612, the hollow chamber 616 is arranged with the guides 615 for the crane trolley 620. The crane truck 620 has a crane truck body 623, crane truck axles 621 and Casters 622 on. The movable end of the energy chain 630 is attached to the crane truck 820 via a support (bracket) 624 and supplies it with energy.

A variant of the second embodiment of the invention is disclosed in Fig. 14a shown. In contrast to the illustrations from the FIGS. 11a . 12a and 13a The rail profile 210 shown here is based on a double-T carrier profile, which is constructed on the basis of two central circular hollow chambers 212, which are connected to one another by two webs. In this rail profile 210 of the crane trolley 220 is arranged to be movable in the lower central region and can be moved along guides 215. The side chambers 219 are partially reinforced double-walled at the respective upper and lower ends.

A variant of the third embodiment of the invention is disclosed in Fig. 14b shown. In contrast to the representation from the FIGS. 11b . 12b and 13b The suspension of the rail profile 310 is not carried out here at the central region of the rail profile 310, but at the upwardly extended side cheeks 311, which additionally each have inwardly facing lugs in the upper region, in the preferred holes 318 are introduced. At the approaches then the suspension of the rail profile 310 is carried on the ceiling of a factory or on a parent chassis carrier.

In Fig. 15 a rail profile 410 is shown, which at the same time located in the central cavity receiving means 416 for an energy chain 430 and two lateral receiving means 419, which may be provided for receiving an energy chain 430 comprises. In the in Fig. 15 shown fourth embodiment of the invention, the lateral receiving areas 419 are designed single-walled. The fourth embodiment is a combination of the first and third embodiments of the invention.

The preferably symmetrically constructed rail profile 410 with a central receiving device 416 and two side receiving devices 419 for energy chains consists of preferably one or as shown two round hollow chambers 412 on each side of each side cheek 411 is arranged. The side cheeks 411 typically include further hollow chambers 413 for stiffening the rail profile 410. In the outer walls of the side cheeks 411, T-slots 414 may be integrated for additional mounting options. Inside the rail profile 410 and below the circular hollow chambers 412, the central receiving device 416 for an energy chain (not in Fig. 15 shown) and / or a crane carriage (not in Fig. 15 shown). The central receiver 416 is composed of a lower energy chain receiving area 416a and the crane car and an upper intake area 416b occupied only by the energy chain. The energy chain is considered big Guided loop inside the receiving device, while the lower part of the energy chain is pushed or pulled by the crane carriage in the receiving area 416a (depending on the direction of movement of the crane carriage) from the crane car, the upper part of the loop of the energy chain in the upper receiving area 416b. The energy chain may comprise guide elements which are movably arranged in the guides 417 of the rail profile. The guide elements of the energy chain can be designed as slide rails and / or guide rollers. The crane carriage is preferably guided along the guide or track rail 415 in the rail section 410. In addition to the central receiving device, two lateral receiving devices 419 are additionally shown, which are formed on the left or right of the central region of the rail profile 410. The lateral receiving means 419 are bounded outwardly by a lower and an upper single-walled side cheek 411b. Inwardly, the lateral receiving areas 419 close to the respective side wall 411a of the central area of the rail profile.

In the art, it is often particularly disadvantageous when loops of a power line 430 hang down when two or three different energy chains 430 are required for a crane rail profile 410. Such multiple allocations are particularly required when, for example, along the crane rail profile 410 requires several different power lines, such as under other pneumatic air lines and additionally power lines.

Often there are regulations or requirements that different types of power lines, such as pneumatic air lines or (electrical) power lines may not be performed in a single or shared receptacle 416, 419, but rather separate receptacles must be provided for each type of power line , In the prior art, therefore, so far several rail profiles were laid side by side, so as to come to enough recording facilities. The disadvantage here is that also the Störraum multiplied and distributed by the majority of juxtaposed rail profiles. This problem was met with support structures, with the help of which several rail profiles are summarized at the headboards. An inventive rail profile with as in Fig. 15 shown three separate receptacles 416, 419 thus simplifies the arrangement of several different energy chains 430 and thus reduces the sturgeon space to a minimum.

In Fig. 16 a rail profile 510 is shown according to the fifth embodiment of the invention. The rail profile 510 corresponds to the in Fig. 15 rail profile shown, with the side walls 511b are constructed zwewandig and for additional reinforcement have at least one hollow chamber, which optionally comprises reinforcing ribs. All other features are the same as those in Fig. 15 shown fourth embodiment.

The rail profiles according to the invention for overhead monorail cranes and slewing cranes can be designed so that they require a small footprint in height and preferably partially rail track suspensions can be integrated into the rail profile.

A rail profile with additional lower side chambers is in Fig. 17 shown. In the lower side chambers 719, 719a, 719b, the energy chain can be inserted, wherein, depending on the position of the crane carriage 720 within the rail profile, a part of the energy chain is arranged in the lower left side chamber 719a in the viewing direction or in the lower right side chamber 719b. The energy chain runs at the in Fig. 17 shown seventh embodiment not vertically, but horizontally. Therefore, the energy chain should preferably have sliding elements on at least the lower side. Sliding elements or roller elements may alternatively also be provided in the hollow chambers 719a, 719b. The advantage of this embodiment is that the left and right side chambers 719c are available for other energy chains and / or other functions. For example, material trolleys could be hung in one of the side chambers 719c, external drives positioned to drive the crane trolley 720, or probes installed. In addition to the side chambers 719, 719a, 719b, 719c, the rail profile 710 has a central hollow chamber 712, further hollow chamber 713 and the hollow chamber 716 with the guides 715 for the crane truck 720. The rail profile 710 has suspensions that may have clamping claws. The suspensions are attached via brackets 770 on the rail profile 710. The brackets consist of a lower plate 770a, an upper plate 770b and fixing screws 870c. The crane truck 720 includes a crane truck body 723, caster axles 722, and caster axles 721. A particular retainer for attaching the mobile end of the power chain is not essential in this embodiment.

In another eighth in Fig. 18 In the embodiment shown, the energy chain can also be guided in an upper hollow chamber 819d of the rail profile 810. Preferably, only the lower part of the energy chain 830 is located in the upper hollow chamber 819d, while another part of the energy chain 830 is arranged above the rail profile 810. The distribution of the energy chain 830 in an upper and lower part depends on the position of the crane trolley 820 in the rail profile. The lower part of the energy chain, which is arranged within the upper hollow chamber 819d, is preferably guided in the illustrated guide 819e. Below the guide 819e for the lower section the energy chain 830, a T-slot 814 is provided, for example, to be able to fix the stationary end of the energy chain 830 on the rail profile 810 or the guide 819e. The eighth embodiment is particularly suitable when the rail profile 810 forms a γ-bridge or part of a in Fig. 19 pictured slewing crane is. In these arrangements, the main disadvantage of not being able to guide the energy chain 830 over a plurality of segments of a rail profile 830 is not negative, since Y-bridges and slewing cranes generally have only one integral rail profile segment. Pendant 871 with holes 871a are designed as a suspension for the rail profile 810 usually for Y-bridges. For swing cranes preferably a fixed suspension is selected. The suspension is fastened to the rail profile 810 via terminal supports 870, the support consisting of a lower plate 870a, an upper plate 870b and fixing screws 870c. This in Fig. 18 rail profile shown has a double-walled construction, that is, the outer walls 811 are almost fully double-walled, as in Fig. 18 shown. Around a central hollow chamber 812 shown here are further hollow chambers 813, the hollow chamber 816 with the guide 815 for the crane carriage 820 and an upper hollow chamber 819d. In the double-walled outer walls a plurality of T-slots 814 and 818 holes are incorporated. The crane carriage has, in addition to a crane truck body 823, rollers 822, which are arranged on roller axles 821 on. The rollers 822 of the crane trolley 820 are guided along the guides 815 of the rail profile 810. The crane trolley 820 is supplied with energy via an energy chain 830, wherein the movable end of the energy chain 830 is fastened to the crane trolley 820 via at least one mounting (retaining bracket) 824 and runs with it. Preferably, two headband 824 are provided, as is the Fig. 18 can be seen. The energy chain 830 consists of a plurality of chain segments 832, which are arranged between a movable end of the energy chain 830 and a stationary end of the energy chain 830. In the energy chain 830 lines for one or more types of energy can be performed. The lines can, for example, carry compressed air, electricity or hydraulic oil. Vacuum lines are also conceivable.

In Fig. 19 is the rail profile made Fig. 18 shown as part of a slewing crane. In contrast to the presentation Fig. 18 a fixed suspension of the rail profile 810 was chosen. Between the pivot crane axis 880 and the distal end of the rail profile 810, a cross brace 881 is provided for better support. At the distal end of the rail profile 810 to the pivot crane axis 880, a screwed-on cover plate 872 can be seen in the upper area. In the lower part of a corresponding cover has been omitted to give an insight into the rail profile 810 and in particular into the hollow chamber 816 with the guides 815 of the crane trolley 820 to allow.
