Definitions
- the invention relates to a tool, in particular for loosening hook screws arranged in rib plates of rail fastenings, which essentially consists of a release element that can be inserted between hook screw and rail, and a tool with a loosening element, in particular for loosening hook screws arranged in rib plates of rail fasteners.
- the rails have already been removed from the rib plate.
- the rail foot of a rail is held in the appropriate position by means of a rib plate which is fastened on a sleeper by means of screws.
- the ribbed plate has recesses or guides into which the screw shaft provided with a hook foot is inserted.
- the hook-like foot has a cross-section, for example a dovetail shape.
- a clamping plate which is tightened by a screw nut, is placed on both sides of the rail foot over the screw shaft inserted into the recess or guide. In this way, the rail finds the firm hold required for track operation by means of the ribbed plate attached to a sleeper.
- hook screw driving tools have been developed which are struck behind the hook screw with a tip against the rail head using a striking tool. In this way the hook foot is driven out of the recess / guide.
- the invention is based on the object of creating a tool, in particular for loosening hook screws arranged in ribbed plates of rail fastenings, which is easy and safe to use, without being endangered by means of a striking tool or by hydraulic or pneumatic force introduction is to be machined, and furthermore, due to its effect, simply drives the screw shaft including the hook out of the recess / guide.
- the release element as a guide sleeve which can be inserted between the hook screw and the rail, partially embracing the rail head and is supported on the rail web, and as a guide sleeve which can be inserted from above into the guide sleeve and slides along a guide surface within the guide sleeve , and is formed in the wedge-shaped space between the hook screw and the guide surface before penetrating expulsion body.
- the release element as a guide sleeve which can be attached to the rib plate and as a guide sleeve which can be inserted from above into the guide sleeve, slides along a guide surface within the guide sleeve and is movable in the direction of the hook screw Expulsion body is formed.
- the guide sleeve is partially open, the parallel side walls connected to one another via the guide surface surrounding the hook screw shank in a loosening position in a parallel arrangement to the ribbed plate.
- the guide sleeve is to be made open in the upper region in which the expulsion body can be used, but it proves to be expedient that the side walls of the guide sleeve are connected to one another at least on the side facing away from the rail and surrounding the expulsion body via a connecting web .
- the design of the guide sleeve which is supported on the web of the rail, permits simple and safe handling of the expulsion body which can be inserted into the guide sleeve from above, the front end of which, which has a wedge-shaped section, is inserted into a positive guide formed between the screw shaft and the guide surface, and in this way obtains a stable position, so that it can perform its actual function by hammer blows from above without any risk and special mounting for the expulsion body.
- Screw shaft from its recess / guide provided in the ribbed plate.
- the prerequisite for loosening the screw shaft is the previous loosening of the screw nut or the removal of the clamping plate.
- the guide sleeve of a tool according to one of claims 1 to 3 can be used together with the expulsion body even when the rail is already removed from the ribbed plate, if it is attached to a shaped body which can be attached to the ribbed plate.
- the shaped body which is matched in its dimensions to the ribbed plate, in particular the spacing of the recesses / guides and the shape of the guide sleeve according to one of claims 1 to 3, aligns the guide sleeve in such a way that the expeller can move in the direction of the hook screw.
- a simple and inexpensive molded body designed as an accessory for a tool according to one of claims 1 to 3 consists of parallel side walls, which are connected to one another via a web facing the rib plate and which carry the guide sleeve.
- a screw connection is an example of a detachable fastening between the guide sleeve and the molded body.
- the guide sleeve in a tool according to one of claims 6 to 8 is at least partially closed surrounding the expulsion body.
- a major advantage of a tool designed in accordance with the features of claims 7 and 8 is that it can be adapted universally to the application in a few simple steps - removal of the screw when the rail is installed or has already been removed.
- FIG. 1 shows a section of a tool according to the invention when used on a ribbed plate with a built-in rail
- FIG. 2 shows a section of a tool according to the invention when used on a ribbed plate with the rail already removed in the starting position
- FIG. 3 shows a front view of the ribbed plate with a hook screw
- FIG. 4 shows a tool according to FIG. 2 after loosening the hook screw in the end position.
- a rail 1 which consists of a rail head 2, a rail web 3 and a rail foot 4, is fastened to a ribbed plate 5, which in turn is fastened to a threshold 7, not shown, by means of screws 6 is attached.
- the ribbed plate 5 has recesses 9 on both sides of the rail foot 4, into which screw shafts 11 with a hook foot or a dovetail-like foot are inserted, with the screw shaft 11 on a not shown provided double spring ring, a clamping plate 10 is set in each case, which is clamped via a screw nut 12.
- the loosening of a screw shaft 11 is shown in the left half of the figure.
- the screw shaft 11 is to be driven out of the recess 9 in the direction of the arrow.
- the tool provided for this activity essentially consists of a guide sleeve 13, which partially includes the rail head 2, and which is supported with a bulge on the rail web 3 or on the rail foot 4.
- the device has a bulge 22 on the side facing the rail web 3, which makes it easier to attach the device.
- An inclined guide 14 is provided within the guide sleeve 13, which consists of two side walls 17 arranged at a distance from one another. At the upper end, the side walls 17 are connected to one another via a connecting web 18.
- An expulsion body 16 can be inserted from above into the guide sleeve 13 and has an inclined surface 19 at the lower end and thus a wedge-shaped section 20. At the upper end, the expulsion body 16 has a striking surface 21, on which hammer blows are to act in the direction of the arrow shown.
- the wedge-shaped section 20 slides along the guide 14 into the intermediate space 15 between the guide 14 and the screw shaft 11 and thus loosens this screw shaft 11 with the hook base arranged in the recess 9. This type of loosening allows the screw shaft 11 to be loosened slowly and thus prevents individual parts from jumping off or flaking off.
- FIG. 1 In order to avoid repetitions, reference is made to the explanations relating to FIG. 1 with regard to the exemplary embodiment according to FIG. 2. 1, the rail 1 has already been removed in the exemplary embodiment of FIG. 2 and the tool explained with reference to FIG. 1 is fastened to a shaped body 23 by means of a screw connection 24.
- the ribbed plate 5 according to FIG. 2 has lateral guides 9, into which the screw shafts 11 are inserted with their feet (FIG. 3).
- Fig.l recesses 9 are shown instead of the guides. 1 can of course also be used on a ribbed plate with guides and a built-in rail.
- the molded body 23 which can be inserted between the guides 9 consists of two parallel side walls 26 which are connected to one another by a web 25.
- the shape of the shaped body 23 is matched to the distance and the height of the guides 9.
- the arrangement of the screw connection 24 between the tool and the shaped body is oriented in such a way that the drive-out body acts on the screw shaft 11 of the hook screw to be driven out (see the end position in FIG. 4).
