Description

[0001] This application is a divisional application of patent application No. 202110895113.2 entitled "Wrapping for Ground Finishing Rollers" filed with the State Intellectual Property Office on August 3, 2021. Technical Field

[0002] The present invention relates to a sheath for a ground finishing roller, wherein at least one roller tool is provided on the sheath, the roller tool having a replaceable bracket and a replaceable tool that can be detachably mounted or mounted on the replaceable bracket. Background Technology

[0003] A ground finishing roller for a ground finishing machine is known from WO 2013 / 017545 A2. The ground finishing roller includes a roller body having a roller sleeve that rotates about a roller rotation axis during ground finishing operation. A plurality of roller tools are mounted on the outer circumferential surface of the roller sleeve. Each roller tool includes a replaceable bracket fixed to the outer circumferential surface of the roller sleeve by welding, the replaceable bracket having a fixed opening formed therein extending substantially radially relative to the roller rotation axis. The replaceable tool to be mounted on such a replaceable bracket includes a retaining rod removable into the fixed opening. The retaining rod received in the fixed opening secures the replaceable tool thereto by clamping or locking action.

[0004] In the construction of a roller tool with a replaceable support and a replaceable tool known from EP 2 843 135 A1, the retaining rod of the replaceable tool, which is introduced into the fixed opening of the replaceable support, is locked onto the replaceable support by a retaining element that is inserted into the lateral opening of the replaceable support and surrounds the engaging retaining rod.

[0005] To detach a replaceable tool secured to a replaceable bracket in this manner, a tool constructed in a pry bar manner is laterally inserted through an opening formed in the replaceable bracket and introduced into the interior space of the replaceable bracket, until the tool is positioned behind a fixed rod of the replaceable tool received in a fixed opening in the replaceable bracket, with the area of ​​force applied. Force is applied to the fixed rod by lever movement or a wedge effect of the tool supported at the roller sleeve, thereby moving it outward in a certain direction from the fixed opening receiving the fixed rod. Summary of the Invention

[0006] The object of this invention is to provide a sleeve for a ground finishing roller, wherein the replaceable tool of the roller tool, which is housed in a replaceable bracket, can be easily detached from the replaceable bracket.

[0007] According to the invention, the objective is achieved by a sheath for a ground finishing roller rotatable about a roller rotation axis for a ground finishing machine. The sheath comprises a plurality of sheath sections arranged or detachable around the roller body of the ground finishing roller, which are circumferentially adjacent to each other. A plurality of roller tools are positioned on the outer side of the sheath sections away from the roller body. At least a portion (preferably all roller tools) of the roller tools includes a replaceable bracket disposed on a respective sheath section and a replaceable tool disposed or detachable from the replaceable bracket. A fixed opening is formed in the replaceable bracket for receiving a fixing rod of the replaceable tool disposed or detachable from the replaceable bracket. A tool penetration opening is provided in the sheath section carrying the replaceable bracket in association with at least one (preferably each) replaceable bracket.

[0008] By providing this tool penetration opening, it is possible for a tool, guided through the tool penetration opening, to act on a fixed rod of a replaceable tool supported on a replaceable bracket, thereby detaching the replaceable tool from the replaceable bracket. Therefore, it is unnecessary to laterally engage the tool into the replaceable bracket using lever-like or wedge-like action. Because this roller tool according to the invention is mounted on a sleeve for the ground finishing roller and not directly on the sleeve of the ground finishing roller itself, the replaceable tool to be replaced can then be detached from the replaceable bracket housing the replaceable tool when the sleeve is removed from the roller body. This, on the one hand, makes the process of removing the replaceable tool from the replaceable bracket housing the replaceable tool significantly simpler, and on the other hand, provides the possibility that, during sleeve handling, the ground finishing machine can be operated either without the sleeve of the ground finishing roller or with other sleeves on the ground finishing roller.

[0009] To obtain direct access to the retaining rod that allows for disengagement, a tool penetration opening associated with at least one replaceable bracket is provided substantially coaxially with the retaining opening formed therein.

[0010] At least one replaceable bracket may be configured with a replaceable bracket interior space (Wechsel-halterinnenraum), wherein a fixed opening provided in the replaceable bracket opens into the replaceable bracket interior space, and a tool penetration opening associated with the replaceable bracket also opens into the replaceable bracket interior space. Here, the replaceable bracket interior space can be provided, for example, by a volume space that preferably extends substantially cylindrically from the fixed opening. Alternatively, this replaceable bracket interior space can be laterally widened relative to the fixed opening, thereby saving structural material and thus weight in such a replaceable bracket.

[0011] If, when a replaceable tool is mounted on at least one replaceable bracket, the retaining rod of the replaceable tool extends into the interior space of the replaceable bracket and is positioned such that the tool engagement end is opposite to or engaged into the tool penetration opening, then the tool engagement end is positioned such that it can be directly applied to the tool engagement end by means of a suitable tool.

[0012] Because the design according to the invention does not require lateral engagement with the replaceable bracket to detach the replaceable tool, a particularly advantageous design proposes that, when the replaceable tool is mounted on at least one replaceable bracket, the internal space of the replaceable bracket is opened substantially only via a tool penetration opening that opens into the internal space of the replaceable bracket. Therefore, lateral engagement openings in the replaceable bracket can be avoided, such that, especially when the replaceable tool is carried in the replaceable bracket, the replaceable bracket covering the tool penetration opening completely closes the tool penetration opening to prevent contaminants from entering.

[0013] Alternatively or additionally, when the replaceable tool is mounted on at least one replaceable bracket, the tool penetration opening is substantially closed by the retaining rod of the replaceable tool. This prevents contaminants from entering the corresponding tool penetration opening.

[0014] The present invention also relates to a method for replacing a replaceable tool disposed on at least one replaceable bracket at a sheath constructed according to the invention, wherein, with the sheath section at least partially disengaged from the roller body, force is applied through a tool penetration opening to a fixed rod received in a fixed opening of at least one replaceable bracket, so as to remove the fixed rod from the fixed opening of at least one replaceable bracket.

[0015] In order to remove a fixed rod that is usually held in a fixed opening by a large force from the fixed opening, it is proposed to apply force by impact and / or compression to remove the fixed rod from the fixed opening.

[0016] For this purpose, for example, a fixing rod can be stressed by means of a force-applying tool that passes through a tool-perforating opening and acts on the fixing rod. Such a force-applying tool can be, for example, a bolt-shaped component.

[0017] Furthermore, it can be suggested that the fixing rod applies force by impacting the force-applying tool with an impact tool. Such an impact tool could be, for example, a hammer.

[0018] The present invention also relates to a ground finishing roller for a ground finishing machine, comprising a roller body and a sheath constructed according to the present invention surrounding the roller body.

[0019] The present invention also relates to a floor finishing machine having at least one floor finishing roller constructed according to the present invention. Attached Figure Description

[0027] exist Figure 1 In this designation, the ground repair machine is generally represented by 10. The ground repair machine 10 includes a rear vehicle 12, which has a drive unit mounted thereon and wheels 14 driven by the drive unit (e.g., a diesel internal combustion engine). In addition, a compartment 16 for an operator to operate the ground repair machine 10 is provided on the rear vehicle 12.

[0028] The ground finishing roller, represented by 20, is rotatably supported on a front vehicle 18, which is pivotally connected to a rear vehicle 12, about its rotation axis W. Figure 2 The ground finishing roller 20, shown in more detail, is constructed by means of a roller body 22 rotatably supported on a front carriage 18. The roller body 22 includes a support structure 28, which in the illustrated embodiment is constructed by means of two support discs, also commonly referred to as rondens, which are rotatably supported on lateral frame regions 30, 32 of the front carriage 18 via corresponding support areas about the roller rotation axis W. The two support discs are fixed, for example by welding, to a generally cylindrical and annularly closed roller sleeve 34 in their outer circumferential region.

[0029] A sheath, integrally indicated by 38, is provided on the outer side 36 of the roller sleeve. In the illustrated embodiment, this sheath 38 comprises six circumferentially adjacent and directly connected sheath sections 40, each section 40 having a segment shell 42 curved to match the circularly curved outer circumferential profile of the roller sleeve 34. Figure 2 It can be identified that the segment shell 42 is connected to each other along the longitudinal edges of the segment shells in the circumferential direction (Segmentschalen- )44 are joined together in a tooth-like manner.

[0030] In the design example shown, the compaction roller 20 is configured as a so-called ground crushing roller, and for this purpose, a plurality of roller tools 48 are provided on the working outer side 46 of the sheath 38 at each sheath section 40. In the example shown, the roller tools 48 are configured with replaceable brackets 50, for example, fixed to the respective sheath section 40 by welding, and replaceable tools 52 in the form of chisels housed in the replaceable brackets.

[0031] Each of the preferred sleeve sections 40, constructed identically and substantially mirror-symmetrically with respect to their longitudinal midpoint, has four connecting regions 54, 56, 58, and 60 spaced axially from each other along the direction of the roller rotation axis W. In each of these four connecting regions 54, 56, 58, and 60, the sleeve section 40 can be fixed to the roller sleeve 34 of the roller body 22, ensuring a stable connection to the roller body 22 along its entire axial length. Here, the connecting regions 54 and 60 located in the axial end regions 62 and 64 of the sleeve section 40 form end connecting regions 66 and 68, respectively, while the connecting regions 56 and 58 located closer to the longitudinal center region of the sleeve section 40 form intermediate connecting regions 70 and 72, respectively.

[0032] In each connecting region 54, 56, 58, 60, one or more fixing mechanisms 76 are provided on the inner side 74 of the section shell 42 facing the outer side 36 of the roller sleeve. Here, the fixing mechanisms 76 provided in the intermediate connecting regions 70, 72 are plate-shaped and are fixed to the section shell 42, for example by welding, so that they extend substantially in the circumferential direction.

[0033] Associated with the plate-shaped fixing mechanism 76, which is disposed in the intermediate connecting regions 70 and 72 and extends substantially in the circumferential direction, a slit-shaped fixing mechanism penetration opening 78, which is also provided in the roller sleeve 34 and extends substantially longitudinally in the circumferential direction, is provided. The fixing mechanism penetration opening is axially adjacent to the corresponding bearing plate of the bearing structure 28.

[0034] A fixing region 80 is formed on the roller body 22 in association with each of these slit-shaped fixing mechanism penetration openings 78 or with each fixing mechanism 76 of the intermediate connecting regions 70, 72 that is to be positioned through such a fixing mechanism penetration opening 78. In the illustrated design example, the fixing region 80 is formed in the radially outer region of the corresponding bearing disc of the bearing structure 28 and includes two openings, for example, provided with internal threads.

[0035] When the corresponding sheath section 40 is installed onto the roller body 22, the plate-shaped fixing mechanism 76 of the intermediate connecting areas 72, 74 is guided through the fixing mechanism penetration opening 78, which is axially disposed directly next to the bearing plate, so that it protrudes radially inward at the inside of the roller sheath. Bolts can be threaded through the openings provided in the fixing mechanism 76 and screwed into the openings of the fixing areas 80 in the correspondingly allocated bearing structures 28.

[0036] The fixing mechanisms 76, located in the end connection regions 66 and 68, are bolt-shaped and extend substantially radially inward at the inner side 74 of the sheath section. The bolt-shaped fixing mechanism 76 is constructed with a threaded foot widened relative to the bolt, which can be welded to the respective section shell 42, thus fixing the bolt-shaped fixing mechanism 76 in the end connection regions 66 and 68 to the section shell 42. It is noticeable that no openings are formed in any region of the fixing mechanism 76 within the section shell 42 that respectively carries the fixing mechanism, for example, to allow the corresponding fixing mechanism to be guided through the section shell. Therefore, particularly in the regions where the fixing mechanism 76 is located on the section shell 42, no openings that would be subject to wear or impair working results are formed on the outwardly exposed outer side of the section shell.

[0037] Associated with the bolt-like fixing mechanisms 76 provided in the end connection regions 66, 68, the roller sleeve 34 has uniform, slit-shaped bolt mechanism penetration openings 78 that extend longitudinally in a substantially circumferential direction. The fixing mechanism penetration openings 78, located in the axial end regions of the roller sleeve 34, have a widening portion in a longitudinal region at their longitudinal midpoint. The widening portion can accommodate the bolt feet of the bolt-like fixing mechanisms 76, which are to be positioned to engage with the fixing mechanism penetration openings 78.

[0038] When the sheath section 34 is radially externally abutting the roller sleeve 34, the bolt-shaped fixing mechanism 76 provided in the end connection regions 66, 68 protrudes radially inward from the roller sleeve 34. Here, each pair of bolt-shaped fixing mechanisms 76 associated with different sheath sections 34 are arranged circumferentially side by side, and surround the engagement device 82 by corresponding grippers, and are thus fixedly held relative to the carrier shell 34.

[0039] In the region of the roller tool 48, a tool penetration opening 84 is formed in the section housing 42 to allow internal access to the replaceable tool 52 and, consequently, to detach the replaceable tool from the replaceable support 50. The tool penetration opening 84 is externally covered by the replaceable support 50, eliminating the risk of material passing through the tool penetration opening 84 or abrasion in the region of the tool penetration opening 84.

[0040] Figure 4 As shown, each replaceable support 50 carried at section 42 is provided with such a tool penetration opening 84, so that when the sheathed section 40 is disengaged from the roller body 22, as referred to below... Figure 5 and 6 The described manner and method allow for the removal of the replaceable tool 52 carried in the replaceable support 50, for example, when the replaceable tool wears out or should be replaced with another type of replaceable tool. Because the process of updating or replacing the replaceable tool 50 can be performed with the sheath section 40 of the sheath 38 removed from the roller body 22, the process of detaching the replaceable tool 52 can be easily performed, and a ground finishing machine can also be used during this process, for example, by placing another sheath 38 on the roller body 22.

[0041] Figure 5 and Figure 6 A replaceable bracket 50 is shown positioned on the outer circumference of the section shell 42 of the roller sleeve section 40. The replaceable bracket can be constructed, for example, as disclosed in documents WO2013 / 017545A2 or EP2843135A1. The replaceable bracket 50 may have two circumferentially adjacent foot regions 86, 88 welded to the outside of the section shell 42, which support or integrally form with the body region 90 and the fixed opening 92 therein. An internal space 94 for the replaceable bracket is formed between the foot regions 86, 88 and the body region 90, radially inwardly bounded by the section shell 42. In the illustrated design example, a studded or protruding retaining rod 96, configured as a chisel—having, for example, a circular (e.g., perfectly circular) cross-sectional geometry—extends through the fixed opening 92 and is positioned within the internal space 94 of the replaceable bracket with a tool-engaging end 98. The fixing rod 96 can be held in the fixing opening 92 that accommodates the fixing rod by clamping or locking, thereby preventing the replaceable tool 52 from disengaging from the replaceable bracket 50 that carries the replaceable tool during operation. The clamping or locking action can be achieved, for example, by providing an annular spring-shaped locking element in the inner circumferential groove 104 that opens toward the fixing opening 92, which can lock into the corresponding outer circumferential groove at the fixing rod 96.

[0042] exist Figure 6 An alternative method for securing the replaceable tool 52 to the replaceable bracket 50 is shown. In the replaceable bracket 50, openings 106, 108 are formed between two foot regions 86, 88, through which the internal space 94 of the replaceable bracket is laterally opened. Retaining elements 110, 112 can be laterally pushed into the lateral openings 106, 108, such that the retaining elements engage with retaining plates 114, 116, respectively carried thereon and constructed of, for example, metal, into circumferential grooves 118 at the retaining rod 96. In this state, the two retaining elements 110, 112 can be securely connected to each other, for example by screwing, thereby protecting them from being removed from the openings 106, 108.

[0043] The tool penetration opening 84, associated with the replaceable bracket 50 and formed in the segment housing 42, is preferably configured such that it is coaxial with the fixed opening 92 or the longitudinal axis L of the fixed opening 92. This means that when the replaceable tool 52 is carried in the replaceable bracket 50, the fixing rod 96, with its tool engagement end 98, is also positioned substantially coaxially with the tool penetration opening 84, and, for example, directly opposite the tool penetration opening. With appropriate sizing, the fixing rod 96 can extend its tool engagement end 98 into the tool penetration opening 84. When the replaceable tool 52 is carried on the replaceable bracket 50, the fixing rod 96, which terminates at or in the tool penetration opening 84 and is configured with a cross-sectional dimension approximately the same as that of the tool penetration opening, substantially covers or closes the tool penetration opening 84, preventing dirt or soil that laterally enters the interior space 94 of the replaceable bracket from reaching the tool penetration opening 84. As described above, since there is no need to access the interior space 94 of the replaceable bracket to disengage the replaceable tool 52, the replaceable bracket 50 can be closed around its entire circumference, especially when the replaceable tool 52 is locked in the fixed opening 92 of the replaceable bracket 50, so that, in principle, dirt cannot enter the interior space 94 of the replaceable tool, which can be provided, for example, through a fixed opening 92 extending radially inward or a volumetric space region connected thereto.

[0044] To detach the replaceable tool 52 from the replaceable bracket 50, for example after the two retaining elements 110, 112 have been removed from the replaceable bracket 50, a force-applying tool 100, for example, configured as a bolt, can be guided through the tool penetration opening 84 to the tool engagement end 98 of the retaining rod 96. Subsequently, an impact tool 102, for example configured as a hammer, can be used to impact the force-applying tool 100, thereby disengaging the retaining rod 96 from the replaceable bracket. This overcomes the frictional clamping effect caused by the slightly conical shape of the retaining rod 96 and the retaining opening 92, and the retaining rod 96 is removed or ejected from the retaining opening 92 until the replaceable tool 52 is completely detached from the replaceable bracket 50. A new or other replaceable tool 52 can then be pushed or pressed into the retaining opening 92 of the replaceable bracket 50 from the outside until the replaceable tool, with its retaining rod 96, is fully received in the retaining opening 92 and supported, for example, by the tool head, in the body region 90 of the replaceable bracket 50. When using the locking connection, a locking state is automatically generated when the retaining rod 96 is pushed in. During installation... Figure 6 In the case of the retaining elements 110 and 112 shown, the retaining elements can be arranged in the openings 106 and 108 of the replaceable bracket 50 in a manner that surrounds the engaging retaining rod 96 after the retaining rod 96 is introduced into the retaining opening 92.

[0045] According to the principle of the present invention, a roller tool with a replaceable support and replaceable tools is disposed at the sleeve, which can be detachably disposed at the roller body in a manner that surrounds the roller body. Therefore, it is possible to: Figure 5 The manner and method shown act on the replaceable tool from the inside of the corresponding sheath section, thereby detaching the replaceable tool from the corresponding replaceable support. This is particularly advantageous because, in principle, it is virtually impossible to reach the roller tool located in the longitudinal intermediate area of ​​the corresponding ground finishing roller from the inside of the roller sheath.

[0046] The principle of this invention can be used in a ground finishing roller that includes a roller body as described in the previously described design example. The roller body itself does not provide a working outer side, but rather serves only as a carrier for a working sleeve provided by a sheath, the carrier being configured in a shape appropriate to the respective work processes to be performed on its working outer side. Therefore, the roller sheath of such a roller body forms only a carrier sleeve, which is arranged and constructed to carry the structure providing the working outer side (i.e., the sheath serving as the working sleeve).

[0047] Alternatively, if the sheath is to be positioned on the outer circumference of the ground finishing roller or roller body, a design according to the invention for the sheath of the ground finishing roller can also be used, wherein the roller body itself can also provide a working outer side. For example, such a roller body or its sheath can provide a substantially smooth, unstructured outer circumferential profile and thus be used, for example, for compacting asphalt materials. If such a ground finishing roller is subsequently used in other work processes, such as for breaking up solid foundations, the ground finishing roller can be surrounded by a sheath comprising the aforementioned structure having multiple sheath sections and roller tools carried on the shells of its sections. In this design, for example, the individual sheath sections can be fixedly connected to each other along the circumferential direction, for example, by screwing, to achieve an annular structure surrounding the sheath of the ground finishing roller.

[0048] It should also be noted that, obviously, the design of the sheath for the ground finishing roller according to the present invention can also be used in conjunction with other replaceable tools. Instead of the pointed chisel shown in this application, for example, a chisel with a cutting edge or a compaction plate can also be used as a replaceable tool in conjunction with a replaceable bracket disposed on the outer circumference of the sheath.
