Description

TECHNICAL FIELD

[0001] The present invention relates to a winch device, in particular for a construction device assembly, comprising a winch drum, a support on which the winch drum is mounted so as to be rotatable about an axis of rotation via a rotary mounting, and at least one rotary drive by means of which the winch drum can be driven to rotate. BACKGROUND

[0002] Winch devices are used in particular in various ways on construction sites or construction device assemblies. Using such winch devices, cables, and in particular lines, can be stored in a compact manner and supplied as required, and in particular can be fed to a construction device in a civil engineering work. For the purposes of unwinding and winding operations, the winch is provided with a rotary drive by means of which the winch drum can be driven to rotate. Usually, the rotary drive is positioned in a side region of the winch drum.

[0003] A universal winch drum for hose lines is known, for example, from EP 3425123 A1. Due to the rotary drive mounted on the side, the width of the winch device is increased, which as a result requires a corresponding amount of installation space. This is undesirable for particularly compact applications.

[0004] In principle, it is known to provide a winch drum with a hub motor, wherein the winch drum is mounted and driven so as to rotate about the fixed hub motor. In such a winch device, the diameter of the winch drum is thus increased, wherein at the same time the hub region within the winch drum is almost completely occupied. This can be particularly disadvantageous, for example, if the hub region is required to supply fluid to one or more hose lines on the winch drum. SUMMARY

[0005] It is an object of the present invention to provide a winch device which allows a particularly compact and also flexible design.

[0006] According to the invention, this object is achieved by a winch device having the following features:

[0007] A winch device comprising:

[0008] - a winch drum comprising a hollow hub region,

[0009] - a support on which the winch drum is mounted so as to be rotatable about an axis of rotation via a rotary mounting,

[0010] - at least one rotary drive by means of which the winch drum can be driven to rotate,

[0011] wherein,

[0012] - the at least one rotary drive is attached to the winch drum, wherein the rotary drive is rotatable together with the winch drum about the rotation axis;

[0013] wherein both rotary drives are arranged in the hollow hub region of the winch drum on opposite sides of the rotation axis;

[0014] the winch drum is designed as a cable drum comprising at least one line or wire harness for conducting fluid, signals and / or electric current, and

[0015] at least one connection is formed on the cable drum for connecting the at least one line or wire harness,

[0016] wherein,

[0017] a rotary feedthrough for at least one fluid and / or at least one signal line and / or electric current is arranged on the rotary mounting, the rotary feedthrough comprising a stator attached to the support in a torque-proof manner, and a rotor rotatable relative to the stator and rigidly connected to the hub of the winch drum, and

[0018] the fluid connection, signal connection and / or electric connection between the support and the line wound on the cable drum is formed by the rotary feedthrough. Preferred embodiments of the present application are set out in the detailed description.

[0019] The winch device according to the present application is characterized in that at least one rotary drive is attached to the winch drum, wherein the rotary drive is rotatable together with the winch drum about the rotation axis.

[0020] One basic idea of the present application is to deviate from the fixed rotary drive in the winch device and instead to move the rotary drive to the rotating winch drum. As a result, there is available mounting space on the support for supporting and mounting the winch drum, and this mounting space can be used for other purposes or for a particularly compact design. In this case, the at least one rotary drive can be attached to the winch drum in almost any position. As a result, a particularly wide variety of different designs of the winch device can be obtained. The winch device can be arranged directly on the construction device or arranged so as to be separate from the construction device, wherein in both cases a construction device assembly within the meaning of the present application is formed.

[0021] A preferred variant of the present application is to provide a power transmission device by means of which power can be transmitted from the fixed support to the at least one rotary drive on the winch drum. For example, for transmitting power, an electric slip contact or a rotary feedthrough for pressure fluid can be provided.

[0022] According to a development of the application, the at least one rotary drive is particularly preferably a hydraulic motor or an electric motor. Here, the hydraulic motor can be supplied with power via hydraulic fluid, wherein the hydraulic fluid is conveyed to the winch drum comprising the at least one rotary drive and is conducted back again via a rotary feedthrough. When using an electric motor, a sliding contact ring, an electric brush or another suitable connection device can be used to transmit electrical power in order to power the rotary drive.

[0023] According to a preferred embodiment of the application, a particularly compact design can be achieved by means of a winch drum comprising a hollow hub region and by means of the at least one rotary drive arranged in the hollow hub region. In this case, the rotary drive can be arranged concentrically with the rotary axis or can be arranged eccentrically with respect to the rotary axis. When the rotary drive is arranged eccentrically, sufficient installation space is available in the center of the winch drum for other components, for example a rotary feedthrough.

[0024] A particularly advantageous configuration of the application is that the winch drum is designed as a cable drum comprising at least one line or cable harness for conducting fluid, signals and / or electrical current, and at least one connection is formed on the cable drum, in particular in the hub region, for connecting the line or cable harness. The line can be formed as a hose line for conducting a fluid, in particular a liquid, a gas and / or a suspension. The free end of the line is in particular connected to the construction device and can thus be fed to the construction device as required via the winch device. The other end of the line is connected to the connection on the cable drum. The connection can in particular be arranged on the outside of the hub region of the winch drum. In particular, a fluid can be supplied to the hose connection via the hub of the winch drum by means of a support in this case.

[0025] The line can also be a cable for conducting data and / or electrical current. It is likewise advantageous for the cable harness to consist of a hose and a cable. The cable harness can in particular be in the form of a band as a so-called conductor band.

[0026] According to a development of the application, it is particularly advantageous for a rotary feedthrough for at least one fluid to be arranged on the rotary mounting, the rotary feedthrough comprising a stator attached to the support in a torque-proof manner and a rotor rotatable with respect to the stator and rigidly connected to the winch drum, and for a fluid connection to be formed between the support and the hose line of the hose drum via the rotary feedthrough. Here, the rotary feedthrough is a component known in principle by means of which a liquid can be transferred from a stationary component to a rotating component. In connection with the present application, the rotary feedthrough can be used not only for transferring a fluid for the hose line, but also for transmitting power, for example in particular hydraulic power, to and from the rotary drive on the winch drum.

[0027] Preferably, the rotary feedthrough is arranged coaxially to the axis of rotation of the winch drum. In this case, the rotor of the rotary feedthrough on the winch drum is in line connection with a hose connection of the winch drum to which the hose line is attached on the winch drum. The hose line is thus stationary with respect to the rotor of the rotary feedthrough and the rotary drive, since all components are attached to the winch drum. Collisions of these components during operation are thus prevented.

[0028] According to a development of the application, a particularly good force transmission can be achieved in that the at least one rotary drive comprises a drive shaft, which comprises a drive pinion, and the drive pinion is in meshing connection with an annular toothed collar, which is arranged concentrically to the axis of rotation on the support. The toothed collar is rigidly connected to the support, so that the toothed drive pinion rolls along the toothed collar like a planetary drive and thus sets the winch drum into rotary motion. In this case, the toothed collar can comprise radially directed inner or outer toothing or spur gear teeth.

[0029] According to a development of the application, it is particularly advantageous in this assembly that the at least one rotary drive is arranged eccentrically on the winch drum. In the process, the rotary drive performs an orbital motion about the axis of rotation.

[0030] A particularly large amount of force can also be transmitted by two rotary drives arranged in the hub region of the winch drum. In this case, the two rotary drives can be arranged opposite one another in the radial direction with respect to the axis of rotation. As a result, an imbalance on the winch drum can be particularly well compensated by the eccentric arrangement of the rotary drives. In principle, three, four or more rotary drives can also be provided on the winch drum in order to be distributed about the axis of rotation. Overall, a relatively compact and cost-effective rotary drive can thus be installed.

[0031] The winch device according to the application can be used in a wide range of applications. According to a preferred configuration of the application, a particularly advantageous application of the winch device is that it is arranged on a construction device assembly, which comprises at least one construction device, in particular a civil engineering device. In this case, the winch device can be provided for a steel cable, for a line for electrical current, a data line or a fluid line.

[0032] According to the application, a particularly advantageous configuration of the construction device assembly is that a civil engineering underground device, in particular a diaphragm wall cutter, is provided. In principle, the hose drum can also be used on other civil engineering devices in which it is advantageous to supply and / or discharge a fluid (for example, drilling fluid in a drilling device), or on a support suspension in a diaphragm wall cutter or diaphragm wall grabber. BRIEF DESCRIPTION OF DRAWINGS

[0033] The invention will now be described in more detail based on preferred embodiments schematically illustrated in the accompanying drawings, wherein:

[0034] Figure 1 This is a rear perspective view of the winch device according to the present invention;

[0035] Figure 2 It comes from Figure 1 The winch assembly is taken from the front perspective view, which has additional details; and

[0036] Figure 3 It is through from Figure 1 A cross-sectional view of the winch device. Detailed Implementation

[0037] refer to Figures 1 to 3 The winch device 10 according to the invention includes a bearing seat-like support 12 to which a disc-shaped connecting plate 14 is securely attached. An annular rotating mounting member 16 is arranged on the connecting plate 14, by means of which the winch drum 20 is self-supporting and mounted so as to be rotatable about a rotation axis 17.

[0038] The winch drum 20 includes a drum-shaped body 22, at the axial end of which a drum wall 24 protrudes radially outward to form a receiving area for receiving a winding of wire 30, which is shown as a wire bundle. Figure 3 As shown, a cutout 25 may be formed in the sidewall 24. The wiring harness may consist of multiple flexible conduits, signal lines, or electrical wires. A disc-shaped hub 26 connected to the swivel mount 16 is formed on the side region of the reel-shaped body 22.

[0039] In the hollow hub region 28 surrounded by the drum-shaped body 22, two inner rotary drive members 40 are fastened to the hub 26 of the winch drum 20 so as to be eccentric to the axis of rotation 17. For this purpose, a fastening flange 27 is formed on the hub 26.

[0040] like Figure 2 As schematically shown, each rotary drive 40 includes a drive axis 44 about which a drive pinion 42 with external teeth is driven to rotate. The drive axis 44 is parallel to the rotation axis 17. The drive pinion 42 meshes with a toothed collar 18 with corresponding internal teeth, wherein the toothed collar 18 is fastened to the connecting plate 14 of the support 12. By means of the meshing engagement of the drive pinion 42, it orbits in a planetary manner along the toothed collar 18 about the rotation axis 17, wherein the winch drum 20 is configured to perform a corresponding rotational motion about the rotation axis 17.

[0041] The shaft-like rotary feedthrough 50 is arranged concentrically to the axis of rotation 17. In this case, the rotary feedthrough 50 comprises a schematically illustrated stator 52, which is non-rotatably connected to the connecting plate 14 and thus to the support 12. A supply line 32 for supplying one or more fluids to the line 30 and / or discharging one or more fluids from the line 30 is connected to the stator 52.

[0042] The rotary feedthrough 50 further comprises a rotor 54, which is rotatable relative to the stator 52 of the rotary feedthrough 50. The rotor 54 is rigidly connected to the hub 26 of the capstan drum 20 and rotates therewith. The line 30 on the capstan drum 20 can be connected via the line connection 31 to a corresponding connection 56 of the rotor 54. In this way, fluids can be transferred from the supply line 32 via the rotary feedthrough 50 to the line 30 on the capstan drum 20.

[0043] In addition to the transfer of one or more fluids, electrical power or signals for the wiring harness, power can also be transmitted via the rotary feedthrough 50 to the rotary drive 40 by means of a schematically illustrated power source 46. As power, hydraulic fluid or electrical current can be transmitted from the outside to the orbitally moving rotary drive 40, in particular via the rotary feedthrough 50.

[0044] By means of the arrangement according to the application, the hose line or electrical line in the form of the line 30 on the capstan drum 20 can be connected to the rotor 54 of the rotary feedthrough 50 in a simple manner, so that not only fluids can be transferred from the outside via the rotary feedthrough 50 to the wiring harness. By means of the internal rotary drive 40 on the capstan drum 20, a particularly compact design of the capstan device 10 can be achieved.
