TECHNICAL FIELD
[0001] The present application relates to a reel device, and more particularly to a reel device including a detachable auxiliary rope arranging device. BACKGROUND
[0002] Reel devices for winding steel wire ropes are widely used in the field of construction machinery. Many technical problems can occur when winding a steel wire rope on a reel of a reel device. These problems include that adjacent turns in the same winding layer of the steel wire rope cannot be closely fitted or are too far apart when the steel wire rope is wound on the reel, commonly known as rope skipping, or that adjacent turns are excessively crowded or even partially overlapped, commonly known as rope overlapping. The same unevenness can also occur between different winding layers. One of the reasons for the occurrence of the above problems is that the deflection angle between the steel wire rope and the surface of the flange is too small when the steel wire rope is wound to the flange of the reel device or at the end of the current winding layer. Although many measures have been taken in the industry to try to perfectly solve this problem, the effect is not ideal. SUMMARY
[0003] The object of the present application is to provide a reel device that can easily adjust the deflection angle of the steel wire rope and has greater versatility.
[0004] The object is achieved by the reel device of the present application. The reel device of the present application comprises: a barrel having a central axis extending in a longitudinal direction, opposite ends in the longitudinal direction, and an outer peripheral surface for winding a rope around the longitudinal direction; two flanges connected to the opposite ends of the barrel; and a deflector comprising an integral deflection portion and a fixing portion and configured to be mounted to a first flange of the two flanges, the first flange having an inner side surface facing a second flange of the two flanges and an outer side surface opposite the inner side surface in the longitudinal direction, wherein the reel device further comprises: a connecting member configured to engage with the fixing portion of the deflector and engage with the first flange in a manner of clamping or abutting the first flange to detachably fix the deflector to the first flange, the deflector being configured such that when fixed to the first flange, the deflection portion protrudes from the inner side surface of the first flange towards the second flange to define an outer surface for contacting and deflecting the rope, wherein the first flange is a circular flange around the central axis when viewed along the longitudinal direction, and correspondingly the deflector is an arc-shaped member around the central axis.
[0005] In one embodiment, the reel device further comprises: a gasket set comprising at least one gasket and capable of providing different thickness configurations configured to be selectively interposed between the inner side surface of the first flange and the opposite surface of the deflection portion when the deflector is fixed to the first flange.
[0006] In one embodiment, the fixing portion comprises a threaded through-hole, the connecting member is a set screw and is configured to fix the deflector to the first flange when threaded into the through-hole and abutting against the first flange.
[0007] In one embodiment, the fixing portion is a part of the deflector portion, the gasket set comprises a hole allowing the set screw to pass through; or the fixing portion is a connecting portion extending from the deflector portion in a longitudinal direction, the first flange comprises an outer profile surface connecting the inner side surface and the outer side surface, and the set screw is configured to abut against the outer profile surface when threaded into the through-hole.
[0008] In one embodiment, the deflector comprises an inner side portion and an outer side portion connected by a connecting portion, the inner side portion and the outer side portion respectively provide the deflector portion and the fixing portion and extend along the inner side surface and the outer side surface of the first flange respectively when the deflector is fixed to the first flange.
[0009] In one embodiment, the outer side surface of the first flange has a surface area inclined extending in a direction radially outward in a manner of gradually reducing the thickness defined by the inner side surface and the outer side surface, and the set screw abuts against the surface area through the through-hole.
[0010] In one embodiment, the inner surface of the outer side portion of the deflector facing the surface area is shaped in a manner of being complementary to the surface area.
[0011] In one embodiment, each gasket of the gasket set has the same shape or size as the inner surface of the inner side portion.
[0012] In one embodiment, the arc-shaped member has a central angle between 30 degrees and 120 degrees.
[0013] In one embodiment, the deflector is one deflector, or the deflector is a plurality of deflectors mounted to the radially outer peripheral edge of the first flange and arranged spaced apart in a circumferential direction; and / or the winding drum device further comprises another deflector for mounting to the second flange, or a plurality of another deflectors mounted to the radially outer peripheral edge of the second flange and arranged spaced apart in a circumferential direction.
[0014] The drum device according to the present application comprises a drum having a drum body and two flanges, a deflector mounted on one or each flange, and a gasket set used together with the deflector, the deflector comprising an integral deflection portion and a fixing portion. The drum device further comprises a connecting member which engages the fixing portion of the deflector on one side and engages the flange in a clamping or abutting manner on the other side, thereby detachably fixing the deflector to the flange. This fixing structure does not require machining of the flange surface of the drum, simplifying the flange machining process, saving costs, and at the same time realizing the detachability, replaceability and reusability of the deflector with the same drum or different drums. The gasket set can comprise one or two or more gaskets and can provide a plurality of thickness configurations with different total thicknesses, and these thickness configurations are provided so that the gasket set is selectively (selectively used or not used) and alternatively (any thickness configuration is selected as needed) clamped between the deflection portion of the deflector and the flange when the connecting member detachably fixes the deflector to the flange. The deflector is configured such that its deflection portion protrudes from the flange when it is fixed to the flange, so as to provide a deflection angle of the rope when the rope is wound onto the flange. By selecting or not selecting the gasket of the gasket set, or selecting different thickness configurations of the gasket combination, the deflection angle of the steel wire rope can be very easily and flexibly changed, especially increased, according to actual needs, to solve the technical problems of uneven winding, rope jumping and stacking of the steel wire rope. Also, since the gasket set with a plurality of thickness configurations is provided, the drum device of the present application can use drums with various flange thicknesses, especially any multi-layer drums that already exist on the market, or in other words, the deflector can be used with various drums. In particular, in the case of transition wear of the deflector by the steel wire rope, a new deflector can be simply replaced to completely solve the problem, and the problem of the deflection angle no longer being suitable or becoming smaller due to the transition wear can also be compensated by changing the gasket combination.

[0022] The present application relates to a reel device for winding and unwinding a rope, such as a steel wire rope, for use in applications such as lifting, hoisting, etc. The reel device of the present application can be used in many industries or engineering machinery fields such as construction, maritime, mining, rescue, etc.
[0023] Figure 1 and 2 Figures 1 and 2 respectively show two different embodiments of a reel device according to the present application.
[0024] The reel device generally comprises a reel and a detachable auxiliary rope arrangement. The reel comprises a barrel 10, usually but not necessarily shaped as one piece, and two flanges 20 and 30. The barrel 10 defines a central axis extending along a longitudinal direction L, and is generally a hollow barrel elongated in the longitudinal direction L as shown. The first and second flanges 20 and 30 are connected to opposite ends of the barrel 10 in the longitudinal direction L, respectively. The barrel 10 provides an outer peripheral surface 14 for winding the rope 12 around the central axis. Figure 3 and 4 As shown, the first and second flanges 20 and 30 can be disc-shaped plates coaxial with the barrel 10, having inner side surfaces 22 and 32 facing each other in the longitudinal direction L, respectively. The inner side surfaces 22 and 32 can be substantially perpendicular to the longitudinal direction L and connected with the outer peripheral surface 14 to limit the two ends of a rope winding layer, respectively. One winding layer is completed when the rope is wound from the inner side surface of one flange to the inner side surface of the other flange during the rope winding process, and then the second winding layer is wound from the inner side surface of the other flange reversely towards the inner side surface of the one flange, and so on.
[0025] The detachable auxiliary rope arrangement can comprise a deflector 40 configured to be fixed to a radially outer peripheral edge or a radially outer profile of any one flange 20, and a gasket set 50 used together with the deflector 40. Figure 1 and Figure 2 The two embodiments in Figures 1 and 2 differ only in that: Figure 1only the first flange 20 of the reel device is provided with the deflector 40 of the present application and the rope 12 wound on the drum 10 is shown; Figure 2 In the second embodiment of the present application, both flanges 20 and 30 of the reel device are provided with the deflector 40 of the present application and the rope 12 wound on the drum 10 is removed, thus exposing the rope groove 16 on the outer peripheral surface 14 of the drum 10. The rope groove 16 extending helically around the central axis serves to precisely position the wound rope 12 in the longitudinal direction L at the appropriate location, or to fix each turn of the first wound layer in the longitudinal direction L.
[0026] The use of the deflector 40 and the spacer set 50 of the present application will be described in detail below with respect to the first flange 20. It will be understood by those skilled in the art that the description of the deflector and the spacer set with respect to the first flange 20 is equally applicable to the deflector and the spacer set installed in the second flange 30 in the Figure 2 In the case where the deflector and the spacer set are installed in the second flange 30.
[0027] In the case where the flanges 20 (and 30) of the reel device are circular flanges around the central axis as shown, the deflector 40 is an elongated member extending in a circular arc, which can have a central axis substantially coaxial with the first flange 20 to which it is installed. The central angle A of the deflector 40 around the central axis can be between 30 degrees and 120 degrees, preferably between 50 degrees and 100 degrees, more preferably 60 degrees or 90 degrees. The size of the central angle A can be determined in advance according to the actual application, more specifically according to the position where the steel wire rope can contact the first flange 20 during winding. Figure 3 ) can be between 30 degrees and 120 degrees, preferably between 50 degrees and 100 degrees, more preferably 60 degrees or 90 degrees. The size of the central angle A can be determined in advance according to the actual application, more specifically according to the position where the steel wire rope can contact the first flange 20 during winding.
[0028] The cross section of the deflector 40 perpendicular to the elongated (circumferential) direction is generally U-shaped. Specifically, referring to Figure 4 and 5 , the deflector 40 can include an inner side portion 42, an outer side portion 44, and a connecting portion 46, which are configured to be located at the (longitudinal) inner side of the first flange 20 facing the second flange 30, the (longitudinal) outer side of the first flange 20 facing away from the second flange 30, and the radial outer side of the first flange 20, respectively, when the deflector 40 is installed to the radially outer peripheral edge of the first flange 20, which collectively define an inner space 45 for receiving a portion of the radially outer peripheral edge of the first flange 20. The inner side portion 42, the outer side portion 44, and the connecting portion 46 have inner surfaces 41, 43, and 47, respectively, which define the inner space 45, and which are configured to face the inner side surface 22, the opposite outer side surface 24, and the radial outer peripheral surface 26 connecting the inner side surface 22 and the outer side surface 24 of the first flange 20, respectively.
[0029] As shown, the outer side surface 24 of the first flange 20 has a surface portion 27 that tapers in a manner that the flange thickness defined by the inner side surface 22 and the outer side surface 24 decreases, to the radial outer peripheral surface 26. Correspondingly or complementarily, the inner surface 43 of the outer portion 44 of the deflector 40 tapers in an expanding manner relative to the inner surface 41 of the inner portion 42 while extending away from the connecting portion 46. The outer portion 44 is formed with threaded through holes 52, such as a plurality of through holes 52, for mounting the set screw 54. Preferably, as shown, the plurality of through holes 52 are evenly spaced in the arcuate elongated direction of the deflector 40. Figure 2 As shown, the outer side surface 24 of the first flange 20 has a surface portion 27 that tapers in a manner that the flange thickness defined by the inner side surface 22 and the outer side surface 24 decreases, to the radial outer peripheral surface 26. Correspondingly or complementarily, the inner surface 43 of the outer portion 44 of the deflector 40 tapers in an expanding manner relative to the inner surface 41 of the inner portion 42 while extending away from the connecting portion 46. The outer portion 44 is formed with threaded through holes 52, such as a plurality of through holes 52, for mounting the set screw 54. Preferably, as shown, the plurality of through holes 52 are evenly spaced in the arcuate elongated direction of the deflector 40.
[0030] The shim set 50 also includes at least one shim or two or more shims of the same or different thicknesses configured to be sandwiched between the inner surface 41 of the inner portion 42 of the deflector 40 and the inner side surface 22 of the first flange 20. The shim set 50 includes at least one shim or two or more shims of the same or different thicknesses to provide a plurality of thickness configurations having different total thicknesses. Optionally, the shim set 50 can include only one shim. In one embodiment, the shim set 50 can include, but is not limited to, one or more shims of 0.5 mm thickness, one or more shims of 1 mm thickness, one or more shims of 2 mm thickness, and so on. Preferably, the shim set 50 or each shim thereof can have a shape and size corresponding to or smaller than the inner surface 41 of the deflector 40.
[0031] As shown, the outer side surface 24 of the first flange 20 has a surface portion 27 that tapers in a manner that the flange thickness defined by the inner side surface 22 and the outer side surface 24 decreases, to the radial outer peripheral surface 26. Correspondingly or complementarily, the inner surface 43 of the outer portion 44 of the deflector 40 tapers in an expanding manner relative to the inner surface 41 of the inner portion 42 while extending away from the connecting portion 46. The outer portion 44 is formed with threaded through holes 52, such as a plurality of through holes 52, for mounting the set screw 54. Preferably, as shown, the plurality of through holes 52 are evenly spaced in the arcuate elongated direction of the deflector 40. Figure 4 and 5 A partial view or enlarged view of the deflector 40 assembled to the first flange 20 is shown. A portion of the radial outer peripheral edge of the first flange 20 is inserted or received into the inner space 45 of the deflector 40, and the shim set 50 is sandwiched between the inner surface 41 of the inner portion 42 of the deflector 40 and the inner side surface 22 of the first flange 20. The set screw 54 is mounted in the through hole 52 of the outer portion 44 and abuts against the outer side surface 24 of the first flange 20. The set screw 54 exerts a force on the deflector 40 in the longitudinal direction L from the second flange 30 toward the first flange 20, causing the inner portion 42 of the deflector 40 to press the shim set 50 against the inner side surface 22 of the first flange 20. The force exerted by the set screw 54 on the deflector 40 is sufficient to secure the deflector 40 to the first flange 20 in all directions, including the radial direction, the longitudinal direction L, and the circumferential direction.
[0032] As shown, the outer side surface 24 of the first flange 20 has a surface portion 27 that tapers in a manner that the flange thickness defined by the inner side surface 22 and the outer side surface 24 decreases, to the radial outer peripheral surface 26. Correspondingly or complementarily, the inner surface 43 of the outer portion 44 of the deflector 40 tapers in an expanding manner relative to the inner surface 41 of the inner portion 42 while extending away from the connecting portion 46. The outer portion 44 is formed with threaded through holes 52, such as a plurality of through holes 52, for mounting the set screw 54. Preferably, as shown, the plurality of through holes 52 are evenly spaced in the arcuate elongated direction of the deflector 40. Figures 4-6The deflector 40 is shown such that during the wire rope winding process when winding from the second flange 30 towards the first flange 20 to the first flange 20 initially, the wire rope contacts the outer surface 49 of the inner side portion 42 of the deflector 40 opposite the inner side 42, the tensioning direction or extension direction of the wire rope (as indicated by the center line Z of the rope) forms a desired deflection angle B (see Figure 7 ) with the inner side surface 22 of the first flange 20, which deflection angle B can be greater than 0.5 degrees, for example between 0.5 and 1.5 degrees. Figure 7
[0033] By selecting different spacer combinations, the total thickness of the spacer set 50 is achieved, the distance R between the outer surface 49 of the inner side portion 42 of the deflector 40 to the inner side surface 22 of the first flange 20 is changeable, thereby achieving the purpose of adjustable, changeable deflection angle of the wire rope. Thus, the drum device of the present application can very simply adjust the deflection angle of the wire rope as needed. In addition, by using the spacer set 50 including different spacer combinations, the deflector 40 of the present application can be applied to different drums, especially used with drums having different thicknesses of the first flange 20 (along the central axis or longitudinal direction L), achieving the versatility of the deflector 40.
[0034] The deflector 40 is fixed to the first flange 20 by the set screw 54, which is simple to assemble and fix without the need for auxiliary structures (such as adjustment brackets). The deflector 40 is detachably fixed to the first flange 20, which makes it possible to solve the problem of the deflector 40 being worn out due to the friction of the wire rope (for example, when the wire rope rubs off the rust-proof paint on the outer surface 49 of the deflector 40, causing the deflector 40 to rust) by simply replacing the deflector 40, which is simple and convenient.
[0035] The deflector 40 is fixed to the first flange 20 by the set screw 54 abutting or abutting against the outer side surface 24 of the first flange 20, which does not require mechanical processing of the outer side surface 24 of the first flange 20, thereby simplifying the flange manufacturing process and saving costs related thereto. The set screw 54 is completely sunk into the through hole 52 and does not protrude out of the outer side portion 44 of the deflector 40, which is very advantageous for applications where space is tight at the outer side surface 24 of the first flange 20. The implementation of the above advantages of the present application does not require a significant increase in the length of the drum device in the longitudinal direction L.
[0036] The deflector 40 of the present application and its advantages are described above with reference to the specific examples of the drawings, but the present application is not limited to the details disclosed above. In general, the present application is a winding device including a deflector 40 detachably fixed to a flange of a winding device, which includes a mounting portion detachably fixed to the flange and includes a deflection portion for contacting a steel wire rope to deflect the steel wire rope by an angle from an inner side surface of the flange when fixed to the flange, and further includes a gasket set interposed between the deflection portion of the deflector 40 and the inner side surface of the flange when the deflector 40 is fixed to the flange, the gasket set including two or more gaskets having the same or different thicknesses. Such a winding device of the present application can be used with a variety of winders having different flange thicknesses, achieving versatility of the deflector 40. The detachable fixation of the deflector 40 to the flange achieves replaceability of the deflector 40. The detachable fixation of the present application is achieved by a set screw, without the need for machining the outer side surface of the flange to which the set screw abuts.
[0037] However, the present application is not limited to the details described above. In some embodiments, in the case where the thickness of the first flange 20 is sufficient, or the first flange 20 can be provided with a protrusion in the longitudinal direction L, the deflector 40 can not include the outer side portion 44, and the through hole for the set screw 54 can be provided on the connecting portion 46, in which case the deflector 40 has a substantially T-shaped cross section. In the case where the thickness of the first flange 20 is insufficient, the above structure can also be achieved by providing at least a partial protrusion on the outer side surface 24 of the first flange 20. In other embodiments, in the case where the thickness of the inner side portion 42 of the deflector 40 is sufficient to ensure that the set screw 54 does not protrude beyond the outer surface 49 of the inner side portion 42, the through hole for the set screw 54 can also be provided on the inner side portion 42 of the deflector 40, while the gasket set 50 includes a through hole allowing the set screw to pass through. In this case, the deflection portion of the deflector 40 simultaneously functions as a fixing portion, and the deflector 40 can not include the outer side portion 44 and the connecting portion 66. As a variation of this structure, the inner side portion 42 of the deflector 40 can be appropriately lengthened on opposite sides in the circumferential direction to function as a fixing portion.
[0038] Alternatively, the deflector 40 can be fixed to the flange 25 by any other detachable connection means. For example, the inner side portion 42 of the deflector 40 includes lengthened portions on opposite sides in the circumferential direction, which can be clamped to the flange 20 using a clamp or the like, without coming into contact with the steel wire rope. In this case, the deflector 40 can also include only the inner side portion 42, in which case the fixing portion of the deflector 40 is provided by the circumferentially lengthened portions of the deflection portion.
[0039] Moreover, the skilled person will understand that the deflector 40 can have any possible structural details, provided that it is capable of being removably fixed (for example by abutment against a fastening screw or by clamping by a clamp) to a fixing portion of the flange, and of protruding from the inner lateral surface of the flange so as to provide the desired deflector for the rope when in contact with it. For example, the deflector 40 does not necessarily have to be configured so as to be complementary to the profile of the radially outer peripheral edge of the flange, in particular in the case where the deflector 40 comprises only the inner portion 42 and the inner portion 42 simultaneously provides both the deflector and the fixing portion functions.
[0040] The skilled person will also understand that, although the first flange 20 and / or the second flange 30 are shown as each having one deflector 40, depending on the application and on the position of the radially outer peripheral edge of the flange that the rope can come into contact with, two or more deflectors 40 can be mounted on the same flange, each deflector 40 having the same or different central angles.
[0041] Some exemplary embodiments of the application have been described above with reference to the accompanying drawings, and some possible variants have also been listed, but the application is not limited thereto. On the contrary, the skilled person will be able to make other modifications to the specific features, structural details, without departing from the principles of the application. All modifications are considered to fall within the scope of protection of the application.
