Definitions
- the present invention relates to a method for installing a hollow rail for guiding an elevator car and/or a counterweight of an elevator installation. Furthermore, the invention relates to a clamping tool for use in such a method.
- An elevator system can be used to transport people and/or objects between floors of a building.
- hollow rails with corresponding running surfaces and/or guide contours can be used, which are anchored in the elevator shaft by means of appropriate brackets and can run vertically therein.
- such hollow rails can be composed of several shorter hollow rail parts.
- the hollow rail parts should be aligned as precisely as possible with one another, in particular in such a way that the hollow rail joints where adjacent hollow rail parts abut one another result in a transition that is as level as possible and free of gaps.
- a first aspect of the invention relates to a method for installing a hollow rail for guiding an elevator car and/or a counterweight of an elevator system.
- the method comprises at least the following steps, which can preferably be carried out in the order given below: (i) arranging a first hollow rail part and a second hollow rail part at different heights in an elevator shaft of the elevator system; (ii) aligning the first hollow rail part relative to the second hollow rail part using an alignment piece so that the first hollow rail part and the second hollow rail part extend along a common longitudinal axis, the alignment piece being arranged between the first hollow rail part and the second hollow rail part such that the alignment piece is partially in an open end of the first hollow rail part and partially extending into an open end of the second hollow rail part; (iii) Fastening a respective clamping element to the first hollow rail part and to the second hollow rail part; and (iv) applying a force to the clamping elements in mutually opposite directions parallel to the common longitudinal axis in order to bring the first hollow rail part and the second hollow
- a respective inner and/or outer contour of the hollow rail parts can vary in their dimensions due to production. Such production-related deviations can complicate the assembly of the hollow rail.
- the use of a special clamping tool for the controlled application of the required assembly forces also makes assembly safer.
- the first hollow rail part and the second hollow rail part can be brought together by means of the clamping elements until they abut one another in order to form a hollow rail joint.
- the alignment piece is at least partially pressed into the open end of the first and/or the second hollow rail part, i.e. sits without play in the respective open end, the hollow rail parts are very precisely aligned with one another.
- a particularly smooth, gap-free transition between the hollow rail parts can thus be created, so that in the best case no additional post-processing is required.
- the alignment can be so precise that the hollow rail joint does not have to be additionally ground in the area of the running surfaces and/or the guide contours, which considerably reduces the assembly effort.
- Hollow rail part can be understood as meaning an elongate, straight hollow profile that is open at its ends.
- each hollow rail part from a be formed from a correspondingly long piece of sheet metal or assembled from several correspondingly shaped pieces of sheet metal.
- Each hollow rail part can have one or more guide contours, which can be used, for example, to guide one or more guide and/or brake shoes. Additionally or alternatively, each hollow rail part can have one or more running surfaces for rollers.
- the guide contours or running surfaces of different hollow rail parts should be as congruent as possible, i. H. with the smallest possible offset to one another, so that the fully assembled hollow rail does not have any excessive steps, gaps or other unevenness at its hollow rail joints, which could cause disruptive noises or vibrations when the elevator car and/or the counterweight is moved or when the brake of the elevator system is actuated, or could increase wear on the rollers.
- first hollow rail part is preassembled.
- a first longitudinal section of the alignment piece can be inserted, for example pressed, into the open end of the first hollow rail part before the hollow rail is installed.
- a second longitudinal section of the alignment piece which protrudes beyond the open end of the first hollow rail part, can then be arranged in a specific orientation opposite the open end of the second hollow rail part and partially inserted there in this orientation.
- the second longitudinal section of the alignment piece can be pressed into the open end of the second hollow rail part, for example up to the stop, by applying a corresponding (pressing) force using the clamping elements.
- the alignment piece is pressed onto the hollow rail on both sides.
- first longitudinal section of the alignment piece is only partially inserted, for example pressed, into the open end of the first hollow rail part during the pre-assembly of the first hollow rail part and is only pressed completely, for example up to the stop, into the open end of the first hollow rail part when the two hollow rail parts are brought together.
- clamping elements are fastened in pairs opposite one another in the vertical direction on the hollow rail parts.
- the fixed clamping elements are mounted horizontally offset from one another.
- several clamping elements are fastened on different sides of the hollow rail parts, preferably on opposite sides of the hollow rail parts, and the force is applied simultaneously or alternately.
- the force can be applied manually, by means of a suitable tool, such as a wrench, and/or by motor.
- a second aspect of the invention relates to a clamping tool for use in a method as described above and below.
- the clamping tool comprises at least the following components: at least two clamping elements, wherein at least a first of the clamping elements can be fastened to a first hollow rail part and at least a second of the clamping elements can be fastened to a second hollow rail part; and a means for applying a force to the first clamping element fixed to the first hollow rail part and the second clamping element fixed to the second hollow rail part in mutually opposite directions parallel to a common longitudinal axis of the first hollow rail part and the second hollow rail part, so that the first hollow rail part and the second hollow rail part move towards one another become.
- the tensioning elements can, for example, be designed to be particularly compact, for example particularly slim or flat. Nevertheless, the clamping elements should be sufficiently stable so that enough force can be transmitted to the hollow rail parts to bring them together completely, i. H. to be able to press together.
- the clamping elements can be releasably fastened to the respective hollow rail part, for example screwed and/or hooked thereto.
- the clamping tool can be designed in such a way that it can be carried, installed and/or operated by a single person.
- the means for applying the force can be formed by a threaded rod passed through both clamping elements.
- the clamping elements can be clamped, for example, between two nuts seated on the threaded rod, with the distance between the clamping elements being able to be reduced by appropriately tightening one or both nuts.
- other means for applying the force are also possible, for example in the form of a pneumatic or electric actuator or a combination of different means.
- Such a clamping tool enables the hollow rail parts to be brought together in a controlled manner, even if high forces have to be applied for this, which can be the case if the alignment piece is to be pressed into one or both hollow rail parts.
- the risk of damage to the hollow rail parts on the one hand and the risk of injury on the other can be reduced.
- the tensioning element can be hooked into the respective hollow rail part in order to fasten the tensioning element to the respective hollow rail part.
- the clamping elements can also be unhooked again after the first hollow rail part and the second hollow rail part have been brought together to form the hollow rail, in particular after the hollow rail parts brought together to form the hollow rail have been fixed, for example by means of a fixing piece (see below). This enables tool-free assembly of the clamping elements in just a few simple steps. The assembly of the hollow rail can thus be further simplified.
- the alignment piece can positively engage in each of the open ends in order to prevent the first hollow rail part from rotating relative to the second hollow rail part about the common longitudinal axis.
- the alignment piece can allow the two hollow rail parts to be displaced relative to one another along their common longitudinal axis.
- the hollow rail parts can be brought together over the alignment piece along their common longitudinal axis, with the alignment piece acting as a guide for the hollow rail parts.
- the hollow rail parts can be brought together over the alignment piece in such a way that the alignment piece disappears completely in the hollow rail.
- the alignment piece can have a base body and at least one rib protruding from the base body.
- the rib can positively engage in a groove of the first hollow rail part and in a groove of the second hollow rail part.
- the base body and the rib(s) can, for example, be made in one piece from the same material.
- a two-part or multi-part design of the alignment piece is also possible, it being possible for the parts of the execution piece to be made from the same material or from different materials.
- the rib or ribs can be made, for example, from a softer material than the base body and/or the hollow rail parts.
- aluminum (alloy) can be a suitable material for the rib(s).
- the rib(s) and the base body are made of aluminum (alloy) and/or another suitable material that is softer than the hollow rail parts.
- This embodiment makes it possible to produce a form fit between the alignment piece and the respective hollow rail part that is also resistant to higher torsional forces, and that with relatively little structural effort.
- At least three ribs can protrude from the base body in different directions.
- the first hollow rail part and the second hollow rail part can each have a groove for each rib.
- the ribs can positively engage in the respective grooves of the first hollow rail part and in the respective grooves of the second hollow rail part. The stability of the form fit between the alignment piece and the respective hollow rail part can thus be further improved.
- the method can also include the following step: arranging an elongate fixing piece between the first hollow rail part and the second hollow rail part, so that a first longitudinal section of the fixing piece protrudes into the open end of the first hollow rail part and a second longitudinal section of the fixing piece protrudes into the open end of the second hollow rail part ; Fixing the hollow rail parts brought together to form the hollow rail using the fixing piece, the first hollow rail part being fixed on the first longitudinal section and the second hollow rail part being fixed on the second longitudinal section.
- the fixing piece can be understood as a fishplate, which in the simplest case can be in the form of a plate or an angle.
- the fixing piece should have sufficient strength to be able to absorb the bending forces acting on the hollow rail joint during operation of the elevator installation without being excessively stressed and/or deformed as a result.
- the fixation piece can be made of steel or another metal alloy, for example, to meet this requirement. It is possible for the fixing piece to be fixed on different longitudinal sides of the first and/or the second hollow rail part, for example screwed thereto. It is also possible for the fixing piece, like the alignment piece, to be arranged completely within the hollow rail after the two hollow rail parts have been brought together. This embodiment enables a permanent and stable fixing of the hollow rail parts that are correctly aligned with one another.
- the first hollow rail part can be fixed to the first longitudinal section by screwing it to the first longitudinal section.
- the second hollow rail part can be fixed to the second longitudinal section by screwing it to the second longitudinal section.
- the hollow rail parts brought together to form the hollow rail can thus be fixed in a simple manner without additional steps for fixing, such as a welding step, being required.
- the dismantling of the hollow rail is simplified.
- the method can also include: removing the tensioning elements after fixing.
- the tensioning elements can be auxiliary tools that are used only temporarily during the installation of the elevator system and are removed from the hollow rail when the elevator system is in operation.
- the fixing piece can be held by the alignment piece.
- the fixing piece can be attached to the first hollow rail part and/or to the second hollow rail part via the alignment piece.
- the fixing piece can be held in the hollow rail exclusively by the alignment piece, as long as the fixing piece has not yet been fixed to the first and/or second hollow rail part. The fixing of the hollow rail parts combined to form the hollow rail can thus be considerably simplified.
- the fixing piece can be held by the alignment piece between the first longitudinal section and the second longitudinal section.
- the alignment piece may be attached to the center of the fixing piece as viewed in the longitudinal direction of the fixing piece. This simplifies the insertion of the longitudinal sections into the respective hollow rail part.
- the fixing piece can be hooked to the alignment piece.
- the fixing piece and the alignment piece be combined with each other by means of a form fit to form an assembly group that can be handled as a unit.
- This enables uncomplicated pre-assembly.
- the fixing piece can be permanently connected to the hollow rail part.
- the alignment piece can be held so that the alignment piece reliably reaches a central position on the hollow rail joint.
- the alignment piece can be made of a softer material, in particular a softer metal or a softer metal alloy, than the first hollow rail part and/or the second hollow rail part. Excessive stress and/or deformation of the first and/or the second hollow rail part when the alignment piece is pressed in can thus be avoided.
- the alignment piece can be made of a softer material than the fixing piece.
- the alignment piece can be an aluminum piece. This enables the alignment piece to be manufactured inexpensively and precisely. On the other hand, excessive stress and/or deformation of the first and/or second hollow rail part when the alignment piece is pressed in due to fitting inaccuracies can be avoided, especially since the hollow rail parts are usually made of (sheet) steel. In this way, the deformation of the first and/or the second hollow rail part during assembly can be reduced in such a way that there is a virtually seamless transition at the hollow rail joint, which requires no further post-processing.
- the fixing piece should be made of a material with a significantly higher strength than aluminum, for example steel or another metal alloy. In this way, forces that load the hollow rail joint during operation of the elevator installation can be largely absorbed by the fixing piece without it being subjected to excessive stress and/or deformation.
- the first tensioning element can be hooked into the first hollow rail part in order to fasten the first tensioning element to the first hollow rail part.
- the second tensioning element can be hooked into the second hollow rail part in order to fasten the second tensioning element to the second hollow rail part.
- the respective hollow rail part can, for example, have a plurality of openings distributed in the longitudinal direction of the hollow rail part for receiving a hook-shaped Have projection of the clamping element, for example in the form of slots or long holes.
- the tensioning element can be attached to the respective hollow rail part in a number of defined longitudinal positions in a simple manner, practically even without the aid of any tool.

- the alignment piece 8 can hold the fixing piece 9 in the middle between the first longitudinal section 10 and the second longitudinal section 11 .
- the two hollow rail parts 4, 5 are aligned with one another using the alignment piece 8, so that the two longitudinal axes of the hollow rail parts 4, 5 lie approximately on a common line, which thus approximately corresponds to a common longitudinal axis 12 of the two hollow rail parts 4, 5.
- the second hollow rail part 5 in this case the upper hollow rail part, being lowered so far in the direction of the (lower) first hollow rail part 4 that a Section of the alignment piece 8 is partially inserted into the open end 7 of the second hollow rail part 5.
- the second longitudinal section 11 of the fixing piece 9 can also be partially inserted into the open end 7 of the second hollow rail part 5 together with the alignment piece 8 .
- the alignment piece 8 can positively engage in each of the open ends 6, 7 in a suitable manner.
- the alignment piece 8 can be pressed into the first hollow rail part 4 for the purpose of pre-assembly (see above) insofar as the ribs 13 are pressed into the corresponding grooves 15 of the first hollow rail part 4 .
- the form fit can also be achieved with a single rib 13 .

- the clamping elements 17a, 17b can be positioned on the respective hollow rail part 4 or 5 in such a way that, after the hollow rail parts 4, 5 have been aligned, they are in pairs opposite one another on different sides of the hollow rail parts 4, 5. ie in such a way that each first clamping element 17a is exactly opposite a second clamping element 17b.
- two clamping elements 17a, 17b are fastened to a left-hand side of the hollow rail parts 4, 5 and two clamping elements 17a, 17b are fastened to a right-hand side of the hollow rail parts 4, 5. This prevents the hollow rail parts 4, 5 from jamming when they are then brought together to form the hollow rail 3.
