Description

[0001] The invention relates to a setting tool for setting a drop-in anchor with the features of claim 1. European patent application EP 0 416 182 A1 discloses a setting tool for setting an anchor with an expansion sleeve and an expansion cone in a borehole. The setting tool comprises a tool holder for connecting the setting tool to a striking tool. A first and a second ram are mounted in the tool holder, by means of which the anchor can be introduced into the borehole and expanded there. The tool holder and the two rams are connected to one another via a ball mechanism. In a first assembly position, the tool holder and the two rams are axially immovable relative to one another. In this position, the anchor can be driven into the borehole. The anchor is not yet expanded and will not be expanded.In a second assembly position, the first and second plungers move relative to each other, whereby the expansion sleeve of the anchor is pushed over the expansion cone and the anchor expands in the borehole.

[0002] The object of the invention is to propose an alternative setting tool that is extremely robust, exhibits low wear, and thus offers a long service life. This object is achieved according to the invention by the features of claim 1.

[0003] The invention relates to a setting tool for setting a drop-in anchor. Such a drop-in anchor is disclosed, for example, in German Offenlegungsschrift DE 10 2014 103 572 A1. Such drop-in anchors have a hollow-cylindrical expansion sleeve for driving into a borehole in a mounting base. After driving the expansion sleeve into the mounting base, an expansion body, in particular an expansion cylinder, is driven into the expansion sleeve, whereby it expands at a front end in the borehole and is thus finally secured. After driving the expansion sleeve into the borehole and driving the expansion body into the expansion sleeve, the setting of the drop-in anchor is complete. The expansion body is arranged captively inside the expansion sleeve, in particular even before setting, and together with the expansion sleeve, forms the drop-in anchor.At one rear end, the expansion sleeve usually has an internal thread for connecting to a fastening element, such as a threaded rod.

[0004] The setting tool according to the invention for setting such a drop-in anchor extends along a longitudinal axis and comprises a first ram-like base body with a first impact surface arranged at a front end for driving in an expansion body of the drop-in anchor. At a rear end, which faces away from the first end, the first base body has a connecting element for connecting to a percussive tool, in particular a so-called hammer drill. In particular, the connecting element is an "SDS adapter." The impact energy of the hammer drill can be transferred to the first base body via the connecting element.

[0005] Here and below, unless otherwise stated, "front end" refers to the end facing the base material during installation. The "rear end" is the end facing away from the base material. For example, the front end of a drop-in anchor is the end that first enters the drill hole during installation.

[0006] The setting tool further comprises a second sleeve-like base body, which is designed, in particular at least in sections, as a hollow cylinder. This second base body has a second impact surface at a front end for driving the expansion sleeve of the impact anchor into the borehole. The second impact surface is designed such that it essentially only comes into contact with an end face at the rear end of the expansion sleeve to be driven in. A diameter of the second impact surface essentially corresponds to a diameter of the end face at the rear end of the expansion sleeve to be driven in. The second impact surface is designed, in particular, as a circular ring.The first base body is guided entirely or at least partially in the second sleeve-like base body so as to be displaceable with respect to the longitudinal axis and the first impact surface, which is essentially designed as a full-surface circular surface, can pass through the second impact surface, more precisely within the second impact surface designed as a circular ring, in an impact direction of the impact anchor, i.e. forwards.

[0007] The setting tool according to the invention further comprises a third sleeve-like base body, which in particular has a support surface arranged at a front end, in particular for indirect or direct support on a surface of the fastening base. The third base body is also at least partially designed as a hollow cylinder. The second base body is at least partially guided in a sliding manner within the third base body. The support surface serves to bear against the surface of the fastening base. If the support surface bears against the surface of the fastening base during setting, the third base body is immovable with respect to the fastening base, but the first and second base bodies are movable with respect to the fastening base and the third base body. The support surface is in particular circular."Indirect" support on the substrate means that the support surface does not need to come into direct contact with the substrate in order to support the third base body, and thus the setting tool itself, on the substrate. A further intermediate support element can be arranged on the third base body, which comes into direct contact with the substrate. Thus, the third base body does not need to directly support the setting tool, but can also merely participate in the support. In particular, the first, second, and third base bodies are made of steel, which ensures high robustness and low wear of the setting tool. All three base bodies are arranged coaxially to one another and are movable relative to one another with respect to their longitudinal axis, in particular in the manner of one or more sliding fits.

[0008] What is essential for the invention is that all three base bodies are connected to one another via a guide in such a way that the setting tool can be brought into a first assembly state in which the expansion sleeve can be driven into the fastening base by a first assembly movement. The first assembly state, or the first assembly movement, is characterized in that the first and the second base body can be moved together in a translational manner along the longitudinal axis. This makes it possible to drive only the expansion sleeve of the impact anchor to be driven into the borehole without displacing the expansion body in the expansion sleeve. The expansion of the expansion sleeve takes place in a second assembly state in a second assembly movement of the setting tool after the expansion sleeve has been properly driven into the borehole to a defined depth in the first assembly state.During the second assembly movement, the expansion body is driven into the expansion sleeve, permanently anchoring and setting the drop-in anchor. The guide according to the invention ensures that only the first base body moves along the longitudinal axis relative to the second and third base bodies during the second assembly movement. The first base body performs a translational movement along the longitudinal axis and is also forced to rotate. In other words, the first base body moves along the longitudinal axis and is rotated about the longitudinal axis, causing the first base body to perform a kind of "helical movement." Due to the guide and the associated movements of the base bodies, the setting tool is extremely robust against wear and tear, requiring extremely low maintenance and versatile for use under a variety of conditions.Generally, the setting tool can be used manually by a worker on a construction site in conjunction with a hammer drill. However, it is also possible to use the setting tool in a construction robot to fully or at least partially automatically anchor the drop-in anchors in pre-drilled boreholes. The first and second assembly movements correspond to the insertion direction of the drop-in anchor into the borehole.

[0009] In an advantageous embodiment of the invention, a control pin connects the first, second, and third base bodies to one another. As a result, the setting tool can be brought into the first and second assembly movements by a translational movement of the first base body along the longitudinal axis. Preferably, the control pin is arranged in a fixed position in the first base body. In particular, the control pin extends orthogonally with respect to the longitudinal axis. Particularly preferably, the control pin penetrates the first base body entirely on two opposite sides of the base body. The translational movement of the first base body can be transferred to the second and third base bodies via the control pin.

[0010] To transmit the movement of the first base body via the control pin to the second and third base bodies, in a further embodiment of the setting tool according to the invention, the second base body has a second guide slot, and the third base body has a third guide slot. The designations "second" and "third" guide slot are chosen to facilitate the assignment of the respective guide slot to the second and third base bodies. The guide slots are each formed as recesses in the respective base body, and the control pin engages in the second and third guide slots. In particular, the recesses completely penetrate the respective base bodies. Preferably, the control pin is flush or almost flush with a surface of the third base body.Particularly preferably, the control pin is flush or almost flush with the surface of the third base body on two opposite sides of the third base body.

[0011] To enable optimal mobility of the base bodies relative to one another, in a further advantageous embodiment of the invention, the widths of the guide rails are identical and correspond to the diameter of the control pin in such a way that a sliding guide is formed between the control pin and the respective guide rail. Jamming of the pin in the sliding guide rails is thus prevented.

[0012] In a particularly preferred embodiment of the invention, the second and third slotted guides are essentially helical in shape with respect to the longitudinal axis. "Helix" is less to be understood as a helical shape, but rather as a type of helix that is elongated with respect to the longitudinal axis. "Helix" does not mean that the slotted guides have the shape of a continuously changing, elongated helix. "Helix" here also includes a shape with sectionally changing, continuous or discontinuous curvatures. The shape of the slotted guides in the second and third base bodies can also differ from one another. Essentially, it is only necessary for the slotted guides to not extend exclusively along the longitudinal axis, but rather have a different direction with a directional component transverse to the longitudinal axis, in order to be "helical."Thus, the respective guide rail ensures that the control pin moves not only in the longitudinal direction, but also at least slightly transversely thereto. The helical guide rails extend in the second and third base bodies, in particular, when viewed along the longitudinal axis, in only one 90° segment of the respective base body. Preferably, the guide rail in the respective base body is formed in two 90° segments each, wherein the two 90° segments are arranged opposite one another with respect to the longitudinal axis. It is not excluded, but is even preferred, that the guide rail, in particular the third guide rail, comprises one or more sections that extend exclusively along the longitudinal axis.In particular, the third slotted guide has a short straight section that transitions into the spiral-like course of the slotted guide such that during the first assembly movement in the first assembly state for setting the expansion sleeve in the borehole, the control pin moves in the straight section, and the first and second base bodies move essentially together and essentially translationally along the longitudinal axis in the insertion direction. As soon as the control pin enters the spiral-like course, the first assembly movement is practically completed, the expansion sleeve is set accordingly, and the setting tool changes to the second assembly movement, or rather, the second assembly state.In the second assembly state, the control pin slides along the spiral guides, the second base body remains essentially stationary and the first base body performs a translational and rotational movement in the insertion direction, whereby the expansion body is driven into the expansion sleeve.

[0013] The straight section, which extends essentially along the longitudinal axis and merges into the helical part of the third slotted guide, can also be considered a control groove. During the first assembly movement, the control pin is preferably arranged in the control groove, and during the second assembly movement, it is arranged in the slotted guide. During the second assembly movement, in a further preferred embodiment of the invention, the second and third slotted guides are essentially congruent with one another. This ensures that essentially only the first base body is moved translationally and rotationally.

[0014] To ensure that the second and third base bodies move essentially only translationally relative to each other along the longitudinal axis and to reduce increased mechanical stress on the guideway, in a further preferred embodiment of the invention, the second and third base bodies are connected to each other by a connecting element, in particular a groove-and-tenon connection. This enables relative movement of the second and third base bodies relative to each other along the longitudinal axis, while preventing rotation of the second and third base bodies relative to each other.

[0015] To ensure that, after completing the setting process of a drop-in anchor, the setting tool returns from the second assembly position to the first assembly position, in which another drop-in anchor can be set, in a further embodiment of the invention, the first and second base bodies are spring-loaded against each other by a first compression spring, and the second and third base bodies are spring-loaded against each other by a second compression spring. This means that the setting process of the drop-in anchor occurs against the spring force of the first and second compression springs.If the impact anchor is set and the setting tool is moved against the insertion direction, the first compression spring between the first and second base body relaxes first and then the second compression spring between the second and third base body relaxes, whereby the setting tool returns to the first assembly position and another sleeve anchor can be set.

[0016] In order to limit the maximum displacement of the impact anchor, or more precisely, the expansion body, in the impact anchor, in a further advantageous embodiment of the invention, the setting tool has a stop element that limits the maximum displacement of the first base body. The stop element is designed, in particular, as a type of stop bushing, which in particular limits the displacement of the first and second base bodies relative to each other, thereby preventing the expansion body from being driven in too deeply. In particular, the stop element is positively connected to the second base body. In particular, the first base body has a type of flange that engages the stop element when a maximum intended setting depth is reached, thereby completing the setting process of the impact anchor. In other words, the first base body moves "to block" against the stop element when the setting process is complete.

[0017] In a further preferred embodiment of the invention, the setting tool has a fourth sleeve-like base body which is arranged coaxially on the third base body. In particular, the fourth base body is screwed onto the third base body. For this purpose, the third base body in particular has a thread and the fourth base body a corresponding counter-thread. The fourth base body is in particular designed as a type of hollow cylinder, wherein a through-opening is at least wide enough for the first base body to pass through it in the setting direction. In particular, the fourth base body has a front end through which the first base body can pass. At the front end, the fourth base body has a receptacle, in particular for clampingly receiving a drop-in anchor to be set.The receptacle is particularly designed such that the expansion sleeve of the drop-in anchor can be flexibly gripped, allowing the drop-in anchor to be picked up, for example, from a magazine. The fourth base body can be screwed onto the third base body in such a way that the fourth base body protrudes beyond the third base body in the insertion direction, and consequently, the setting tool is supported on the substrate via the fourth base body. Thus, support can be provided directly via the fourth base body and indirectly via the third base body, to which the fourth base body is preferably attached.

[0018] Preferably, the receptacle is formed by a flexible perforated disc, in particular made of an elastomer. The flexible perforated disc is held in place, in particular, in a form-fitting manner at the front end of the fourth base body. This form-fitting connection allows a worn perforated disc to be easily replaced if necessary.

[0019] The present invention also relates to a hammer drill, i.e. a percussive and rotating tool in combination with a setting tool according to the invention according to claim 14. The connecting element, in particular the SDS adapter, is arranged in a tool holder of the hammer drill.

[0020] Claim 15 claims the combination of a setting tool according to the invention with a drop-in anchor, which can be placed into a borehole with the setting tool. The drop-in anchor comprises a hollow cylindrical expansion sleeve and an expansion body received therein. The expansion sleeve can be expanded at a front end by driving the expansion body into the expansion sleeve.

[0021] The features and combinations of features, embodiments, and refinements of the invention mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or drawn in a figure, can be used not only in the respective specified or drawn combination, but also in any other combinations or individually. Embodiments of the invention are possible that do not have all the features of a dependent claim. Individual features of a claim can also be replaced by other disclosed features or combinations of features. Embodiments of the invention that do not have all the features of the exemplary embodiment are possible.

[0022] The invention is explained below using an embodiment.

[0023] They show: Figure 1 shows a setting tool according to the invention in a sectional side view in a first assembly position in combination with a drive-in anchor accommodated in the setting tool; Figure 2 shows the combination with the setting tool according to the invention of the Figure 1 , after driving the drop anchor into the borehole, but before the drop anchor is anchored; Figure 3 the setting tool of the Figure 1 in a second assembly position and with the impact anchor fully anchored in the borehole; Figure 4 the setting tool in the state of Figure 1 in a perspective view; Figure 5 the setting tool in the state of Figure 2 in a perspective view; and Figure 6 the setting tool in the state of Figure 3 in a perspective view.

[0024] In the Figures 1 to 3 The setting tool 1 according to the invention is shown in combination with a drop-in anchor 2 in different states. Figures 1 and 2show the setting tool 1 in a first assembly state and Figure 3 shows the setting tool 1 in a second assembly state. Figures 4 to 6 the setting tool 1 is shown in states that essentially correspond to the states of the Figures 1 to 3 correspond, however, the setting tool 1 is shown in a perspective view in each case. The following section first discusses the essential parts of the setting tool 1, followed by an example of the setting process for a drop-in anchor 2. For reasons of clarity, not all reference numerals are included in all figures.

[0025] The setting tool 1 is suitable for setting or anchoring a drop-in anchor 2 in a borehole 6 in a fastening base 5. The drop-in anchor 2 comprises an expansion sleeve 4, which is introduced into the borehole 6, and an expansion body 3, which, as soon as the expansion sleeve 4 has been introduced into the borehole 6 to a desired depth, is driven into the expansion sleeve 4, whereby the latter expands in the borehole 6 and the drop-in anchor 2 is thus permanently anchored in the borehole 6. For setting, the drop-in anchor 2 is driven into the borehole 6 in the driving direction E.

[0026] The setting tool 1 comprises a first ram-like base body 7, which extends along a longitudinal axis L. The first base body 7 is made of steel and has a front end 8. A first impact surface 9 is arranged at the front end 8. This serves to engage with the expansion body 3 in order to drive it into the expansion sleeve 4 of the impact anchor 2. The first impact surface 9 is circular and designed as a full circle, and a diameter of the first impact surface 9 corresponds to a diameter of the expansion body 3 with respect to the longitudinal axis L. At a second end 10 of the first base body 7, a connecting element 12 in the form of an SDS adapter is formed. The connecting element 12 serves to connect the first base body 7 and thus the setting tool 1 itself to a percussive / rotating tool, in particular a hammer drill (not shown). A circular flange 11 borders the connecting element 12.The first base body 7 is rotationally symmetrical with respect to the longitudinal axis L.

[0027] A second hollow-cylindrical base body 13 is arranged coaxially and displaceably on the first base body 7. The first base body 7 and the second base body 13 are displaceable relative to one another along the longitudinal axis L. The second base body 13 extends along the longitudinal axis L between a front end 14 and a rear end 15. A second impact surface 16, which is circular in shape, is arranged at the front end 14. The second impact surface 16 serves to transfer impact energy to the expansion sleeve 4 in order to drive it into the borehole 6. A diameter of the second impact surface 16 with respect to the longitudinal axis L corresponds to a diameter of the expansion sleeve 4 with respect to the longitudinal axis L.

[0028] A third sleeve-like base body 17 is arranged on the second base body 13 coaxially to the longitudinal axis L. The third sleeve-like base body 17 extends along the longitudinal axis L between a front end 18 and a rear end 20. The third sleeve-like base body 17 is displaceable relative to the first and second base bodies 7, 13 with respect to the longitudinal axis L. At the front end 18, the third base body 17 has a support surface 19. This support surface 19 can be used to bear against the surface of the fastening base 5. If this is the case, the setting tool 1 is supported directly via the support surface 19 of the third base body 17 on the fastening base 5 (not shown). At the rear end 20 of the third base body 17, a thread 21 is arranged on an outer circumference, as shown in the Figures 4 to 6 can be seen. Its function will be explained below.

[0029] A fourth sleeve-like base body 22, shown only in the Figures 1 to 3 , is screwed onto the third base body 17, opposite to the driving direction E. For this purpose, the fourth base body 22 has a counter thread 27 at a rear end 26 for the thread 21 on the third base body 17. The fourth base body 22 is thus stationary with respect to the third base body 17. At its front end 23, the fourth base body 22 has a receptacle 24 in the form of a flexible perforated disc 25 made of an elastomer. The perforated disc 25 is positively fastened in the fourth base body 22. The perforated disc 25 serves to grip a drop-in anchor 2 to be driven into the borehole 6 by its expansion sleeve 4 and to place it at the borehole mouth of the borehole 6 (shown in Figure 1). For this purpose, the perforated disc 25 for gripping the drop-in anchor 2 is "slipped" over the expansion sleeve 4 of the drop-in anchor 2. Because the perforated disc 25 is only inserted in the fourth base body 22 with a form-fitting fit, it can be easily replaced if necessary, e.g., in the event of wear. The front end 23 of the fourth base body 22 serves to support the setting tool 1 on the fastening base 5. The support is transferred to the third base body 17 via the thread 21 and the counter thread 27, whereby the support by the third base body 17 is only indirect and the support surface 19 therefore does not come into direct contact with the fastening base 5.

[0030] In the first assembly state, shown in the Figures 1, 2 , 4 and 5, the first and the second base body 7, 13 are jointly movable translationally along the longitudinal axis L in a first assembly movement. In the second assembly position, or in the second assembly movement, only the first base body 7 is moved translationally with respect to the longitudinal axis L and during this translational movement is additionally forced to rotate with respect to the longitudinal axis L. To achieve this, the setting tool 1 has a guide 28, which for reasons of clarity is only shown in the Figures 4 to 6is shown. The guide 28 is essentially formed by a second slotted guide 29, which is arranged in the second base body 13, and a third slotted guide 30, which is arranged in the third base body 17. The assignment of "second and third" slotted guides to the "second and third base body" was used for reasons of consistency. The setting tool 1 shown does not have a "first slotted guide" on the first base body 7. The second and third slotted guides 29, 30 each extend helically in the form of an elongated helix along the respective base body 13, 17 with respect to the longitudinal axis L. Generally, the respective slotted guides 29, 30 are realized by openings in the respective base bodies 13, 17.The second and third slotted guides 29, 30 have essentially an identical course, but the third slotted guide 30 additionally has a control groove 31, which is essentially formed at the rear end 20 of the third base body 17 and merges into the third slotted guide 30. The control groove 31 extends parallel to the longitudinal axis L. A control pin 32 penetrates the first base body 7 on two opposite sides. The control pin 32 is stationary with respect to the first base body 7 and consequently moves translationally and rotationally with the first base body 7 with respect to the longitudinal axis L. The control pin 32 engages in the second and third slotted guides 29, 30 and is almost flush with the surface of the third base body 17 on both sides.The width of the control pin 32 corresponds to the width of the two guide rails 29, 30, such that the control pin 32 can slide along the guide rails 29, 30 without jamming. Generally speaking, the first, second, and third base bodies 7, 13, 17, together with the second and third guide rails 29, 30, form a type of sliding guide. A first compression spring 35 urges the first base body 7 against the second base body 13, and a second compression spring 36 urges the second base body 13 against the third base body 17, as shown in FIGS. Figures 1 to 3 can be seen. A connecting element 33 in the form of a groove-and-tenon connection 34 between the second and third base bodies 13, 17 ensures that the second and third base bodies 13, 17 can only move translationally relative to each other along the longitudinal axis L. Rotation relative to the longitudinal axis L is prevented.

[0031] Figure 4shows the setting tool 1 in its initial state, or in the first assembly state. In this state, both compression springs 35, 36 are relieved. To clarify the function of the setting tool 1, Figures 4 to 6 The fourth base body 22 is not shown. This allows a view of the guide 28. In the Figure 4In the state shown, a drive-in anchor 2 to be set can be gripped and guided to the mouth of a borehole 6. In this state, the control pin 32 is arranged in the control groove 31 and the second and third guide rails 29, 30 are displaced relative to one another. If impact energy is now transferred to the connection element 12 in the insertion direction E, the control pin 32 slides forward until it enters the third guide rail 30. Up to this point, the first and second base bodies 7, 13 are moved together in the insertion direction E in order to drive in the expansion sleeve 4. During this movement, the first and / or second compression springs 35, 36 are compressed. If the control pin 32 enters the third guide rail 30, the two guide rails 29, 30 are congruent, shown in Figure 5. With continued movement of the first base body 7, the setting tool 1 reaches the second assembly state, or rather it performs the second assembly movement, during which the control pin 32 is forced along both link guides 29, 30. The first base body 7 continues to move forward in a translational and also rotational manner with respect to the longitudinal axis L in order to drive the expansion body 3 into the expansion sleeve 4. The two compression springs 35, 36 are further compressed. During this movement, the second base body 13 remains essentially stationary. At the end of the expansion process of the drop-in anchor 2, the flange 11 comes into contact with a stop element 37. The movement of the first base body 7 is stopped, the expansion body 3 can no longer be driven deeper into the expansion sleeve 4, the expansion sleeve 4 is expanded as planned, and the setting process of the drop-in anchor 2 is completed.If the setting tool 1 is now moved out of the borehole against the impact direction E, the two springs 35, 36 relax and the setting tool again takes up the position in the . Figures 1 and 4 shown basic state or the first assembly state. Now, another impact anchor 2 can be anchored in another borehole 6 (not shown) using the setting tool 1 according to the invention.
