Description

The invention relates to a kit for cables comprising a cable drum, a drive motor, a transmission unit and a support frame.

It is known to use cables essentially in two different designs.

The main variant of the different types is the so-called C-shape, in which the drive motor below (or above) is arranged in the support frame mounted winch or cable drum, so that in the side view about a C-shape results. The transmission is usually arranged on the lateral end plates of the support frame.

The other variant of the different types is the so-called coaxial shape in which the drive motor is laterally flanged quasi in extension of the cable winch axis or cable drum drive shaft to the end plates of the support frame with the interposition of the transmission. Here, the engine output shaft and the cable drum drive shaft are arranged coaxially with each other.

The C-shape has the advantage of being compact, while the coaxial shape is slim.

Cables in C-shape or a kind of coaxial shape are for example from the DE 10 2010 048 946 A1 , the DE 10 2005 046 900 A1 , the DE 195 30 891 A1 and the DD 42 513 A3 known.

In addition, kits are generally known, for example from the of Pahl and Beitz wrote textbook "Design - Methods and Application" in the 3rd edition from 1993, page 589ff ,

From the DE 1 951 272 U is a kind of modular system with respect to built-in precision input gear for winches known. In this case, a drive motor can be designed either on its own without a built-in precision input gear or with a built-in input gear in a short C-shape variant or a long C-shape variant. To the To mount each C-shape variant, various gearbox, pinion and gears are used. Also, the drive motor can be arranged in each case to form a C-shape variant on different sides of the transmission of the winch.

The provision of two fundamentally different designs such as the C-shape and the coaxial shape requires a very high cost.

There is therefore a desire to reduce this effort.

The object of the invention is therefore to provide a way that allows to reduce the cost of parallel provision of different types of cables, especially in C-shape and coaxial shape or similar design.

This object is achieved by the reproduced in claim 1 modular system for cables and the method according to claim 10. The dependent claims indicate further advantageous embodiments of the invention.

Provided according to the invention is a construction kit for cables comprising a cable drum, a drive motor, a gear unit and a support frame, wherein the kit comprises various gear housing parts for the gear unit to allow the assembly of a cable either C-shaped or quasi coaxial form.

Under quasi coaxial or a design in quasi coaxial form is understood here an arrangement in which the motor output shaft, that is the output shaft of the drive motor, and a rotation axis of the cable drum forming shaft in the sense of a cable drum drive shaft are not coaxial (see above), but shifted by at least 5 cm, but less than 50 cm to each other or are offset or arranged, depending on the specific design and in particular load capacity. The offset of the waves to each other can be done approximately at right angles but also diagonally.

In other words, it has thus been recognized according to the invention that when on a complete coaxiality is dispensed with and only an almost coaxial arrangement or quasi-coaxial shape is sufficient, it is possible to make do with different gear housing parts for the C-shape and quasi coaxial shape, since then the other transmission components can be assembled only in a different arrangement to be rebuilt between a C-shape and a quasi-coaxial shape or to determine the final design during assembly and set solely by selecting the appropriate gear housing part on C-shape or quasi coaxial shape.

In a structurally simple manner according to the invention, it is provided here that a first housing for the C-shape and a different second housing for the quasi-coaxial shape is provided as different gear housing parts, the first housing is designed so that the transmission unit as the first transmission unit for the C-shape can be mounted and hereby the design of the cable to be mounted on the C-shape can be fixed, and the second housing is designed so that the transmission unit can be mounted as a second gear unit for the quasi coaxial shape and hereby the design of can be fixed to the quasi-coaxial form.

It is advantageously provided that the first housing of first housing shells and the second housing of second housing circuits is assembled. Preferably, in this case, the first housing is longer than the second housing.

In a structurally simple manner is also provided that the housings are formed so that to form the first or second gear unit each identical waves, in particular an output shaft, preferably additionally two intermediate shafts and particularly preferably additionally an input shaft, in a different arrangement for C-shape and the quasi-coaxial shape can be stored in the corresponding housing.

Furthermore, it is advantageously provided that the kit for both gear units the same parts in the form of waves, in particular an output shaft, preferably additionally two intermediate shafts and particularly preferably additionally an input shaft, for the assembly of the cable, in particular corresponding gear unit, in C-shape or quasi coaxial form comprises.

This makes it possible in departure from the previous approach, the gearbox or the transmission unit within special housing shells for the C-shape or quasi coaxial shape with the same other parts (waves, pinion, etc.) only put together differently. Thus, only different gear housing parts, that is, housing or corresponding composite housing shells need to be stored.

In an advantageous manner, therefore, only one set of transmission components, in particular shafts, pinions and gears, must be kept available for a respective gear ratio, regardless of the selected design. Bearings and other standard parts may vary depending on the design.

The remaining parts of the cables, such as cable drum, drive motor and support frame can remain the same in departure from the previous procedure. Due to the purchased offset can be used for both types identical components, especially in the transmission or the transmission unit itself. Only the housing shells and the arrangement of the gear parts in the shells are specific to the particular design.

The gear housing parts or housing shells are therefore used in addition to the recording and storage of the transmission components and the provision of connection or connection and attachment points to accomplish the particular design when mounting the drive and the cable drum together with the support frame.

Optionally, another input shaft may be used, as needed, in particular, as required by the quasi-coaxiality, to increase the degree of approximation to the exact coaxiality, i. keep the distance of the axes of rotation of the waves as small as possible and still enjoy the advantage of easy conversion. In particular, this is a so-called flying storage of the input shaft, so a one-sided storage.

The kit can therefore also include different input shafts for the C-shape and quasi coaxial shape.

In an advantageous manner, it is provided that the shafts of the gear unit are arranged in the C-shape in their longitudinal direction almost lying on a line, preferably two intermediate shafts between an input shaft and an output shaft. The taking place for the C-shape arrangement of the transmission shafts (or their longitudinal center axes) almost in a line is in the front view of FIG. 2 good to see. In other words, the waves extend parallel to each other approximately within a common plane.

In contrast, the transmission shafts are arranged in the quasi coaxial form nested, like the FIG. 4 shows. It is thus advantageously provided that the shafts of the gear unit are arranged nested in the quasi-coaxial form, preferably an input shaft between an output shaft and two intermediate shafts.

So it is achieved a modular design and it can be used in both designs all the usual attachments.

Also provided according to the invention is a method for converting a cable pull, comprising a cable drum, a drive motor, a gear unit and a support frame, between a C-shape arrangement and a quasi-coaxial-form arrangement, to which end the gear unit using different housings, in particular special housing shells, which are composable to the various housings, for the C-shape or coaxial shape when using the same parts, in particular identical waves, within the respective housing is merely assembled differently.

Further features and details of the invention will become apparent from the following description of the figures. Show it:

In the FIG. 1 is a perspective and schematic exploded view of a modular box 1 according to the invention for cables shown. In this overview, the modular design of the kit 1 according to the invention or of the parts of the kit 1 optionally in C-shape or quasi coaxial form composable cable is recognizable. The modular system designated as a whole with 1 is thus a kind of modular cable system and comprises as essential parts a drive motor 2 or as in FIG. 1 show two drive motors 2, which are preferably designed as an electric motor, and the following components, with which a first gear unit 3A for the C-shape and a second gear unit 3B for the quasi-coaxial form can be mounted. By driving connection of the drive motor 2 with one of the two gear units 3A, 3B, a motor-gear unit arrangement can be produced and thus the design of the cable to be mounted or manufactured in C-shape or quasi coaxial form can be fixed. To form the C-shape, the first gear unit 3A has first housing shells 11A, which can be assembled to form a first housing 10A of the gear unit 3A. In a corresponding manner, the second gear unit 3B for forming the quasi-coaxial form comprises second housing shells 11B, which can be assembled to form a second housing 10B of the second gear unit 3B. The differences of the housings 10A and 10B or their housing shells 11A and 11B will be explained in more detail below with reference to the corresponding figures.

Also, the kit 1 comprises a cable drum 4 and a support frame 5, of which the cable drum 4 is received and rotatably supported. About the corresponding motor-gear unit arrangement, the cable drum 4 is driven. The carrying the cable drum 4 supporting frame 5 can be assembled with the corresponding motor-gear unit arrangement optionally to a cable in C-shape or quasi-coaxial form. In the present case, it is hinted to better understand that the cable to form a Monorail crane can be attached to the bridge 6.

The bridge 6 comprises for connection to the support frame 5 of the cable perforated attachment points 7, which are provided in pairs outside in the end region on the longitudinal sides.

The attachment points 7 are penetrated by the rods 8 of the support frame 5.

The support frame 5 comprises a substantially rectangular or square face plate 9, which receives in its corners in each case one of three rods 8 and also centrally provides a storage for the cable drum 4.

On the side facing away from the end plate 9, the three rods 8 engage in the corresponding housing 10A or 10B of the respective gear unit 3A or 3B in an analogous manner in order to connect the gear unit 3A, 3B to the cable drum 4 in a driving manner.

Depending on the desired design, the drive motor 2 can be flanged onto the gear unit 3A, 3B or its housing 10A, 10B on the same side as the cable drum 4 (C-shape) or on the opposite side of the cable drum 4 (quasi-coaxial form).

The gear units 3A and 3B comprise apart from the different housing shells 11A or 11B of the respective housing 10A, 10B for the C-shape or quasi-coaxial shape otherwise identical parts, in particular shafts, pinions, gears, etc., only different within the respective housing shells 11A (C-shape) and 11B (quasi-coaxial shape) are arranged. For this purpose, the housing shells 11A, 11B dimensioned accordingly designed differently, so that therein the required arrangement and mounting of the parts described below is possible to form the C-shape or the quasi-coaxial shape.

With reference to the FIGS. 2 to 5 this will be clarified below.

In the Figures 2 and 3 the C-shape is shown in more detail, whereas in the FIGS. 4 and 5 the quasi coaxial shape is shown in more detail.

It can be seen that each gear unit 3A, 3B always comprises the following four shafts: a first shaft 12 which serves as an input shaft of the gear unit 3A, 3B and is drivingly connectable to the engine output shaft, a second shaft 13 serving as the output shaft of the gear unit 3A, 3B and thus serves as a cable drum drive shaft, and a third shaft 14 and fourth shaft 15, each serving as an intermediate shaft.

In the design in C-shape, the waves are 12 to 15 with their longitudinal central axes in the representation of FIG. 2 , ie seen in the longitudinal direction of the waves 12 to 14, approximately on an imaginary line. For this purpose, shafts 12 to 14 are arranged so that they extend parallel to each other approximately within a common plane. In this case, the two shafts 14, 15 serving as intermediate shafts are arranged in their longitudinal direction between the shaft 12 serving as the input shaft and the shaft 13 serving as the output shaft. The first housing 10A for the C-shape is for this purpose made longer than the second housing 10B for the quasi-coaxial shape, since the corresponding offset between the mounted in the housing 10A shafts 12 and 13 must be achieved to implement the C-shape.

In the case of the design in quasi coaxial form, however, the waves 12 to 15 are apparently nested. Here, the input shaft (shaft 12) is arranged between the output shaft (shaft 13) and the two intermediate shafts (shafts 14 and 15). Thus, the housing 10B may be formed less elongate than the housing 10A, since only the required for the quasi-coaxial shape small offset between the mounted in the housing 10B shafts 12 and 13 must be achieved and thus the nested arrangement of the shafts 12 to 15 more compact than the arrangement of the shafts 12 to 15 for the C-shape. As a result, the quasi-coaxial shape is similarly slim to the C-shape as a complete coaxial shape. In particular, in this case, the intermediate shafts (shafts 14 and 15) are arranged in their longitudinal direction around the input shaft (shaft 12) and in particular on one side of the input shaft (shaft 12) and the output shaft on an opposite side of the input shaft. As a result, the input shaft between the output shaft and the two intermediate shafts arranged. In contrast, in the C-shape, both intermediate shafts (shafts 14 and 15) are arranged on one side of the input shaft (shaft 12) facing the output shaft (shaft 13).

The shafts 12, 14 and 15 each have a pinion 12R, 14R, 15R indicated by the suffix R, and the shafts 13, 14 and 15 are each associated with a gear 13Z, 14Z, 15Z designated by the suffix Z. The pinions 12R, 14R, 15R and the gears 13Z, 14Z, 15Z mesh as in FIGS Figures 3 and 5 indicated corresponding to each other.

In both the C-shape and the quasi-coaxial form, the shafts 12 to 15 with their pinions R and gears Z mesh from the input shaft to the output shaft equally in the order of 12-14-15-13 and 12R-14Z-14R, respectively -15Z-15R-13Z, so that the same ratio is achieved regardless of the design.

The serving as an input shaft first shaft 12 may be formed differently for both types as described above, the other waves 13, 14, 15 with their pinions and gears are the same, that is identical, used for both types and only as described depending on Design accordingly arranged differently in the respective housing 10A or 10B.
