Description

The invention relates to a mounting frame for moving and fixing in a shaft according to the preamble of claim 1.

The WO 2017/016780 A1 describes an assembly frame for moving and fixing in a shaft in the form of a support component for moving and fixing in an elevator shaft of an elevator system. The assembly frame has a rigid base frame in the form of a rack. Primary fixing components in the form of extendable stamps are fixedly arranged on a first side of the base frame, by means of which the assembly frame supports itself on the first shaft wall when fixed. A secondary fixing component with an immovable and elongated secondary support element in the direction of movement is arranged on a second side of the base frame opposite the first side of the base frame in a fixing direction and thus a horizontal direction. The assembly frame can support itself on a second shaft wall opposite the first shaft wall in the fixing direction when fixed via the secondary support element. Due to the necessary dimensions of the assembly frame for stable fixation in the shaft and the implementation of desired assembly steps in the shaft, transporting the assembly frame to a shaft is very complex. This applies in particular to the insertion of the mounting frame before starting and removing it after completion of an installation in the shaft.

The EN 102018208588A1 and JPH10147481A also describe mounting frames for moving and fixing in a shaft. EN 10 2018 208588 A1 discloses a mounting frame according to the preamble of claim 1.

In contrast, the object of the invention is in particular to propose an assembly frame for moving and fixing in a shaft, which is particularly easy to handle, i.e. in particular transportable and can be brought into and removed from a shaft. According to the invention, this object is achieved with an assembly frame with the features of claim 1.

The mounting frame according to the invention for moving and fixing in a shaft has a base frame, a first primary fixing component for supporting the mounting frame on a first shaft wall and a secondary fixing component for supporting the mounting frame on one of the first shaft walls in a Fixing direction opposite the second shaft wall of the shaft when fixing the mounting frame in the shaft. The first primary fixing component and the secondary fixing component are arranged on the base frame. According to the invention, the first primary fixing component and/or the base frame can assume a transport position and a working position, wherein a change of the first primary fixing component and/or the base frame from its working position to its transport position leads to a reduction in an extension of the mounting frame in an extension direction deviating from the fixing direction. The dimensions of the mounting frame with the first primary fixing component and/or the base frame in the transport position, i.e. in a transport state of the mounting frame, are therefore smaller in the extension direction than with the two components in their respective working position, i.e. in a working state of the mounting frame.

The assembly frame is in the working state in particular when it is in the shaft and enables assembly work to be carried out in the shaft. It is in the transport state in particular when it is to be transported to a shaft. When inserting it into and removing it from the shaft, both states or a mixed state of the assembly frame are generally possible. A mixed state is characterized by the fact that either the first primary fixing component or the base frame is in its transport position and the other component is in the working position. When inserting it into and removing it from the shaft, the assembly frame in particular has a mixed state in which the first primary fixing component is in the working position and the base frame is in the transport position. In this case, the base frame in the shaft is brought from the transport position to the working position after it has been inserted and from the working position to the transport position before it is removed.

The small dimensions of the assembly frame in transport state enable easy transport to a shaft, for example from one shaft to the next shaft, i.e. within a building or between buildings. Such transports must be carried out in particular on a construction site with many obstacles and also between buildings, for example by means of a truck. In addition, the small dimensions enable the assembly frame to be easily inserted into the shaft and removed from the shaft.

In addition, the separation of the transport state and the working state of the assembly frame enables the dimensions of the assembly frame in the working state to be optimally designed to meet the requirements during assembly in the shaft. For example, the first primary fixing component can be designed without regard to the requirements during transport of the assembly frame so that the assembly frame can be securely and stably fixed in the shaft in the working position of the first primary fixing component. The first primary fixing component can, for example, protrude far beyond the base frame in its working position. The base frame can, for example, be designed so that in its working position it has dimensions that enable assembly steps to be carried out optimally in the shaft.

The extension direction mentioned corresponds in particular to a direction of displacement in which the assembly frame is displaced in the shaft. In the case of a vertical shaft, this corresponds to the perpendicular or vertical. The reduction in the extension of the assembly frame when changing from the working state to the transport state therefore corresponds to a reduction in the height of the assembly frame. The extension direction can also deviate from the direction of displacement, in particular be inclined relative to the direction of displacement, for example inclined by 5 - 45° relative to the direction of displacement. In this case too, a reduction in the extension of the assembly frame in the extension direction leads to a reduction in the height of the assembly frame.

The height of the mounting frame is designed in such a way that it is lower than the usual height of doors by a sufficient safety margin when transported. The height of the mounting frame is, for example, a maximum of 190 cm. This means that the mounting frame fits through a door of a normal height without tipping over, which makes it particularly easy to transport the mounting frame within a building. The width of the mounting frame when transported should not exceed 80 cm. This means that doors to be passed through during transport do not have to be particularly wide, but can be designed as standard doors.

The mounting frame can be used to hold a mechatronic installation component, for example in the form of an industrial robot. By means of the mechatronic Installation components allow automated assembly steps to be carried out in the shaft when the assembly frame is fixed. The dimensions of the base frame in its working position can then advantageously be designed so that the industrial robot can optimally accommodate tools or assembly material, such as screws or anchor bolts, arranged at least indirectly on the base frame. For this purpose, a certain distance between the industrial robot and the tool or assembly material is necessary, which leads to a necessary extension of the base frame in the extension direction and thus to a necessary height of the assembly frame, which can be significantly greater than the maximum height of 190 cm mentioned above.

The mechatronic installation component can, for example, correspond to the automated installation component of the WO 2017/016780 A1 However, the assembly frame can also, for example, support an installation platform or be designed as an installation platform from which a fitter can carry out assembly steps by hand or with the help of tools in the shaft.

A shaft is understood here to be an elongated space delimited by shaft walls. The shaft has in particular a mainly rectangular cross-section, although other cross-sections are also conceivable. The shaft runs in particular in a mainly vertical direction, so that the direction of displacement also runs mainly in a vertical direction and the fixing direction accordingly mainly in a horizontal direction. The shaft is arranged in particular in a building, although it can also be arranged, for example, in a bridge, a pillar or on a ship. The shaft walls consist in particular of concrete reinforced with reinforcements. However, they can also be made of metal, for example. The shaft serves in particular as an elevator shaft of an elevator system in which a cabin for transporting people and/or objects is moved in the direction of displacement when the elevator system is operating. The shaft can also serve other purposes, for example it can be used as a ventilation shaft or to accommodate pipes, electrical cables or the like.

The mounting frame can be moved within the shaft in the direction of displacement and thus positioned at different locations, in particular at different heights within the shaft. For this purpose, the mounting frame is particularly Supporting means, for example in the form of a rope, a chain or a belt, suspended from a displacement component, in particular in the form of a winch. The supporting means can be wound up or unwound by the winch and the assembly frame can thus be moved in the shaft.

The base frame can be designed as a simple platform, frame, scaffolding, cabin or similar. It is made in particular from metal, for example metal profiles.

In its working position, the first primary fixing component is arranged on the base frame in a particularly immobile manner relative to the base frame, i.e. without the possibility of movement relative to the base frame. Immobile arrangement is to be understood here as meaning that it can only move minimally relative to the base frame, if at all. A deformation of a first primary contact element of the first primary fixing component, which rests against the first shaft wall when the assembly frame is fixed, is in particular not a movement of the primary fixing component relative to the base frame. A first primary contact element is in particular designed as a rubber buffer. The rubber buffer is attached to the base frame via a metal arm, for example. The assembly frame has in particular several, specifically two or four primary fixing components, although not all of them have to be able to assume both a transport position and a working position. It is also conceivable that primary fixing components can only assume a working position.

The secondary fixing component has in particular at least one controllable actuator, for example in the form of an electric spindle drive or a hydraulic or pneumatic piston-cylinder unit, by means of which a secondary contact element of the secondary fixing component, which rests against the second shaft wall when fixing in the shaft, can be displaced outwards, i.e. away from the base frame in the direction of the second shaft wall. The actuator and associated parts of the secondary fixing device are fixed immovably to the base frame, i.e. screwed on, for example. The second fixing component can also have more than one secondary contact element. It is also possible for the mounting frame to have more than one secondary fixing component, each with at least one secondary The actuator is controlled by a control device, which can also perform other tasks, such as controlling the relocation component or any mechatronic installation component.

According to the invention, the first primary fixing component has an arm and a first primary support element arranged on the arm. In the working position of the first primary fixing component, the arm extends away from the base frame in the direction of extension. To change from the working position to the transport position of the first primary fixing component, at least part of the arm is displaced towards the base frame. This enables a particularly simple change from the working position to the transport position of the first primary fixing component and back.

The arm of the first primary fixing component is arranged on the base frame so that it can pivot, for example via a joint or a pivot axis. When changing from the working position to the transport position, the arm is pivoted towards the base frame so that the first primary support element and at least part of the arm are displaced towards the base frame. The pivot axis mentioned can run, for example, in the fixing direction or perpendicular to the fixing direction and the displacement direction, i.e. horizontally along the first shaft wall. It is also possible for the arm to be arranged so that it can be displaced in the extension direction relative to the base frame and for the arm to be displaced together with the first primary support element towards the base frame when changing from the working position to the transport position. Both when pivoting and when displacing, the arm is secured in both the working position and the transport position by means of a lock, for example a bolt.

The first primary contact element rests against the first shaft wall when the mounting frame is fixed and is designed, for example, as a rubber buffer. The arm mentioned can be made of metal, for example, and can also extend away from the base frame in the direction of the first shaft wall. An arm of a primary fixing component can also have more than one primary contact element, for example two or four contact elements. It is also possible for the mounting frame to also more than one primary fixation component, for example two or four primary fixation components, each with one or more primary attachment elements.

In particular, in the transport position of the first primary fixing component, no part of the first primary fixing component protrudes beyond the base frame in the direction of extension. This enables particularly small dimensions of the assembly frame in the direction of extension in the transport position.

According to the invention, the mounting frame has a second primary fixing component with a second primary support element for supporting the mounting frame on the first shaft wall when fixing the mounting frame in the shaft. The second primary fixing component is arranged so immovably on the base frame that no part of the second primary fixing component protrudes beyond the base frame in the direction of extension. The second primary fixing component can therefore only assume one working position. This enables a particularly secure and stable fixation of the mounting frame in the shaft without the dimensions of the mounting frame increasing in the direction of extension when the mounting frame is in transport.

The assembly frame has in particular two first primary fixing components, which can assume both a working position and a transport position, and two second primary fixing components, which can only assume a working position. The arms of the two first primary fixing components are in this case arranged in a pivotable manner on the base frame.

However, it is also possible for the assembly frame to have four first primary fixing components, all four of which can assume both a working position and a transport position. In this case, the arms of the four first primary fixing components are arranged on the base frame in a particularly movable manner. The four arms are particularly firmly connected to one another or form a single component.

In both cases, the four system elements are arranged in such a way that they form corners of a rectangle whose edges run in the direction of displacement and in a transverse direction perpendicular to the direction of displacement and the direction of fixation.

In an embodiment of the invention, each primary system element is assigned a support component for supporting the mounting frame on the first shaft wall of the shaft when the mounting frame is moved in the direction of displacement. In addition to a secure and stable fixation of the mounting frame in the shaft, this also enables the mounting frame to be moved safely without the risk of damage to the mounting frame or the shaft walls.

The support means described above has, in particular, an oblique pull in relation to the vertical in the direction of the first shaft wall. This ensures that the assembly frame is actually supported by the support component on the first shaft wall during relocation and that it does not hang freely in the shaft, which could lead to it hitting a shaft wall and thus causing damage to the assembly frame and the shaft wall. The assembly frame has, in particular, a compensating element which counteracts the tilting of the assembly frame in the direction of the first shaft wall during relocation. The compensating element is, in particular, designed in accordance with a compensating element of the WO 2018/162350 A1 executed.

The support components in particular have rollers that can roll along the first shaft wall in the direction of displacement. The rollers can also be designed to pivot about a pivot axis perpendicular to the first shaft wall, so that rolling along the first shaft wall transverse to the direction of displacement is also possible. The support components can also have sliding elements, for example, such as ceramic blocks. In this case, the sliding elements can slide along the first shaft wall. The assembly frame in particular has several, specifically four, support components. These are arranged in particular so that they form corners of a rectangle, the edges of which run in the direction of displacement and in a transverse direction perpendicular to the direction of displacement and the fixing direction.

The support components are at least partially arranged so as to be movable relative to the base frame on the base frame. This means that it is directly or indirectly fixed to the base frame, for example screwed on, and at least some parts of the support component are movable relative to the base frame. If the support component has a roller, there is in particular an axis around which the roller can rotate when rolling along the shaft wall, and thus the roller is arranged so as to be movable relative to the base frame in the fixing direction. The axis can, for example, be arranged so as to be displaceable in the fixing direction on a holder that is firmly fixed to the base frame. If the support component has a sliding element, the aforementioned cuboid can, for example, be arranged so as to be displaceable in the fixing direction on a holder that is firmly fixed to the base frame. The support components are in particular designed and arranged in such a way that they rest on the first shaft wall via the support component even when the mounting frame is fixed - i.e. in their fixing position.

In an embodiment of the invention, the primary contact element is arranged on the outside of the support components in the working position in the direction of displacement. This enables particularly safe and stable support when fixing the assembly frame. The primary contact elements and the support components are arranged in particular in such a way that they each form corners of a rectangle, the edges of which run in the direction of displacement and in a transverse direction perpendicular to the direction of displacement and the fixing direction.

In an embodiment of the invention, the base frame is designed in several parts and at least two parts of the base frame that are aligned in the direction of extension can be moved relative to one another, in particular can be moved into one another. This enables a particularly simple and cost-effective construction of the base frame.

The parts of the base frame mentioned are designed, for example, as hollow profiles, in particular metal hollow profiles. In order to move the base frame from the working position to the transport position, a first part is pushed further into a second part of the base frame. An inner contour of the second part is adapted to an outer contour of the first part so that it can accommodate the first part. The hollow profiles can, for example, have a rectangular or round cross-section. To secure the working position and the transport position, the parts can Have through holes into which a bolt can be inserted, thus preventing the parts from moving relative to one another.

In an embodiment of the invention, the assembly frame has an adjustment device by means of which the base frame can be moved from the transport position to the working position and vice versa. This makes it particularly easy to move the base frame from the transport position to the working position and back. The adjustment device is designed in particular in such a way that the position of the base frame can be changed even when the base frame is in the shaft. This advantageously makes it possible for the assembly frame to be brought into the shaft in the transport position of the base frame and only then for the base frame to be brought into the working position. This makes it easy to insert the assembly frame into the shaft.

The adjustment device can be operated by hand, for example, and for this purpose can have a hand crank, by means of which the parts of the base frame can be moved against each other via Bowden cables. The adjustment device can also have a controllable actuator, for example in the form of an electric spindle drive or a hydraulic or pneumatic piston-cylinder unit, by means of which the parts of the base frame can be moved against each other.

In an embodiment of the invention, the base frame is designed in several parts and at least two parts of the base frame that are aligned in the fixing direction can be moved relative to one another, in particular can be moved into one another. This means that the extension of the base frame in the fixing direction can be changed and thus adapted to the dimensions of the shaft. The assembly frame can therefore be used in shafts of different designs and is therefore particularly flexible. In addition, particularly small dimensions of the base frame in the fixing direction and thus of the assembly frame can be adjusted for transport. This enables the assembly frame to be transported particularly easily.

The mutually displaceable design of the two parts mentioned is achieved in particular by a first part being inserted into a second part to different extents inserted into one another and secured in the desired position, for example with a bolt. The two parts are designed, for example, as hollow profiles, in particular metal hollow profiles, with an inner contour of the second part being adapted to an outer contour of the first part so that it can accommodate the first part. The hollow profiles can, for example, have a rectangular or round cross-section. The adjustment of the base frame to the shaft, i.e. the displacement of the aforementioned parts of the base frame relative to one another, is carried out in particular by hand and thus without actuators. The adjustment takes place in particular in a preparatory phase before the assembly frame is moved in the shaft for the first time. The setting of a particularly small dimension of the base frame for transport can take place inside or outside the shaft.

In an embodiment of the invention, the secondary fixing component has a secondary support element which has an elongated shape in the direction of displacement and is made up of several parts. The elongated shape enables support on the second shaft wall, even if this has openings, for example door openings in an elevator shaft. The secondary support element has such a large extension, in particular in the direction of displacement, that it is larger than a maximum extension of an opening in the second shaft wall. The secondary support element has in particular a mainly beam-shaped basic shape.

A multi-part design of the secondary system element means that at least part of the secondary system element can be easily dismantled and assembled. The aforementioned dismantling and assembly changes the extension of the system element in the direction of extension. This means that the aforementioned part can be dismantled for transport of the mounting frame, which makes the mounting frame particularly easy to transport. In addition, by selecting the appropriate assembled part, the secondary system element can be adapted to different shafts, in particular to different heights of door openings. The secondary system element is designed in such a way that it can only be assembled after the mounting frame has been inserted into the shaft. This can be done, for example, by a fitter who has access to the shaft and thus to the mounting frame via a door opening.

The secondary attachment element consists of three parts, whereby a middle piece can be firmly connected to the remaining parts of the secondary fixing component. An end piece can be dismantled and reassembled at the top and bottom of the middle piece.

In an embodiment of the invention, the secondary fixing component has a secondary contact element which has an elongated shape in the direction of displacement and is designed to be completely removable. This enables particularly easy transport of the assembly frame.

A detachable design of the secondary contact element should be understood to mean that it can be completely separated from the remaining parts of the secondary fixing component. The secondary contact element can be designed in one piece or preferably in several parts as described, in which case the middle part of the secondary contact element can also be detachable.

In an embodiment of the invention, the secondary fixing component has an actuator as described above, by means of which the secondary contact element can be displaced in the fixing direction and thus a distance of the secondary contact element to the base frame can be changed. The secondary contact element can thus be moved away from the base frame and thus into a fixing position and towards the base frame and thus into a displacement position. The secondary fixing component is designed in such a way that a distance of the secondary contact element to the base frame in the fixing direction can also be changed independently of the actuator of the secondary fixing component. This means that the base frame can be positioned in the fixing direction in the shaft at a desired position when the mounting frame is in the fixed state.

This embodiment of the invention, i.e. the described possibility of changing the distance of the secondary contact element to the base frame in the fixing direction independently of the actuator of the secondary fixing component, can be advantageously implemented independently of a described elongated shape of the secondary contact element.

The described design of the secondary fixing component with the possibility of changing the distance of the secondary contact element from the base frame in the fixing direction independently of the actuator of the secondary fixing component can also be advantageously implemented in an assembly frame without the features described above, that the first primary fixing component and/or the base frame can assume a transport position and a working position, wherein a change of the first primary fixing component and/or the base frame from their working position to their transport position leads to a reduction in an extension of the assembly frame in an extension direction deviating from the fixing direction. This leads to an assembly frame for moving and fixing in a shaft with a base frame, a first primary fixing component for supporting the assembly frame on a first shaft wall and a secondary fixing component for supporting the assembly frame on a second shaft wall of the shaft opposite the first shaft wall in a fixing direction when fixing the assembly frame in the shaft. The secondary fixing component then has an actuator by means of which the secondary contact element can be displaced in the fixing direction and thus a distance of the secondary contact element to the base frame can be changed. The secondary contact element can thus be moved away from the base frame and thus into a fixing position and towards the base frame and thus into a displacement position. The secondary fixing component is designed in such a way that a distance of the secondary contact element to the base frame in the fixing direction can also be changed independently of the actuator of the secondary fixing component.

The described possibility of changing the distance of the secondary installation element to the base frame in the fixing direction independently of the actuator of the secondary fixing component is particularly advantageous when a mechatronic installation component is arranged on the base frame. This can therefore also be positioned at a desired position in the fixing direction in the shaft. It can therefore be positioned in such a way that it can carry out all the intended assembly steps, in particular it can reach the necessary places on the shaft walls. The base frame should be positioned in the fixed state of the assembly frame, for example, so that the mechatronic installation component is arranged centrally in the shaft in the fixing direction. The alignment in the horizontal Direction transverse to the fixing direction can be adjusted by appropriate positioning of the mounting frame in the shaft during the preparation phase mentioned above. In addition, particularly small dimensions of the secondary fixing component in the fixing direction and thus of the mounting frame can be adjusted for transport. This enables particularly easy transport of the mounting frame.

For this purpose, the secondary contact element of the secondary fixing component is connected to the actuator in particular via two parts, which are designed to be movable relative to one another in the fixing direction, in particular to be displaceable into one another. The design of the said parts so that they are movable relative to one another can be achieved in a similar way to the movable parts of the base frame described above.

The described mounting frame can be used particularly advantageously as part of an assembly device for carrying out automated assembly steps in a shaft. The assembly device also has a mechatronic installation component, as already described above.

The assembly device described can be used particularly advantageously as part of an assembly system for carrying out automated assembly steps in a shaft. The assembly system also has a displacement component for displacing the assembly device in the shaft, as already described above.

Further advantages, features and details of the invention will become apparent from the following description of embodiments and from the drawings, in which identical or functionally equivalent elements are provided with identical reference numerals. The drawings are merely schematic and not to scale.

First, the Fig.1 and 2 received. According to Fig.1 An assembly system 10 for carrying out automated assembly steps has a displacement component in the form of a winch 12, which is arranged on a shaft ceiling 14 of a shaft in the form of an elevator shaft 16. The elevator shaft 16 is delimited by a total of four shaft walls, of which in the Fig.1 only a first shaft wall 18 and a second shaft wall 20 opposite in a fixing direction 40 are shown. In the Fig.2 a third shaft wall 19 and a fourth shaft wall 21 opposite the third shaft wall 19 are also shown. The elevator shaft 16 has accordingly Fig.2 has a mainly rectangular cross-section and runs mainly in a vertical direction, being limited at the top by the shaft ceiling 14. A shaft floor opposite the shaft ceiling 14 is not shown. The second shaft wall 20 has an opening in the form of a door opening 23, into which a shaft door is inserted when an elevator system is installed in the elevator shaft 16.

The winch 12 is connected via a support means in the form of a rope 22 to an assembly frame 24 of an assembly device 26 for carrying out automated assembly steps in the shaft 16. The rope 22 can be wound up or unwound by the winch 12 and the assembly frame 24 and thus the assembly device 26 can be displaced in the elevator shaft 16, i.e. pulled up and lowered. The assembly frame 24 and thus the assembly device 26 can thus be displaced in a vertical displacement direction 27 in the elevator shaft 16. A mechatronic installation component in the form of an industrial robot 28 is arranged on the assembly frame 24, by means of which automated assembly steps can be carried out in the elevator shaft 16. The industrial robot 28 is designed, for example, like a WO 2017/016780 A1 described industrial robot and can, for example, automatically carry out the assembly steps described there.

The assembly frame 24 and the industrial robot 28 thus form the assembly device 26 for carrying out automated assembly steps. The assembly device 26, the rope 22 and the winch 12 thus form the assembly system 10 for carrying out automated assembly steps.

The assembly frame 24 has a multi-part base frame 30. The base frame 30 has a mainly cuboid-shaped middle part 32, on which the industrial robot 28 is arranged hanging downwards. The middle part 32 can accommodate further components of the assembly device 26 or the assembly frame 24 (not shown), such as a control device and/or a compressor for providing compressed air. The middle part 32 can be closed off from the outside by a housing (not shown). A side of the middle part 32 oriented towards the second shaft wall 20 forms a second side 47 of the base frame 30.

The middle part 32 is followed by three horizontally running cross beams 34a, 34b, 34c, which are spaced apart from one another in the direction of displacement 27. The cross beams 34a, 34b, 34c are constructed in two parts, whereby a first part 36a, 36b, 36c arranged in the direction of the middle part 32 can be inserted into a second part 38a, 38b, 38c arranged in the direction of the first shaft wall 18. The two parts 36a and 38a, 36b and 38b or 36c and 38c are each arranged in alignment in the fixing direction 40 and can be secured against one another with a bolt (not shown). This allows the expansion or extent of the base frame 30 in the fixing direction 40, which runs horizontally and perpendicular to the first shaft wall 18 and to the second shaft wall 20, to be changed.

The lowest cross beam 34c is connected in the direction of the first shaft wall 18 to a two-part longitudinal beam 42 running in the direction of displacement 27. A first part 49 arranged in the direction of the cross beam 34c can be inserted into a second part 51. The two parts 49, 51 are arranged in alignment in the direction of displacement 27 and can be secured against each other with a bolt (not shown). This allows the expansion or extension of the base frame 30 to be changed in the direction of displacement 27 and thus in an extension direction. The base frame 30 can assume a working position and a transport position, with the Fig.1 the working position is shown.

The longitudinal beam 42 forms a first side 45 of the base frame 30. At the lower end of the longitudinal beam 42, two horizontal supports 43 are arranged, which extend into the elevator shaft 16 and can carry one or more magazines with assembly material, such as screws or anchor bolts, when the assembly device 26 is in operation. The base frame 30 is therefore made up of the middle part 32, the three cross beams 34a, 34b, 34c, the longitudinal beam 42 and the supports 43. The aforementioned parts of the base frame 30 are connected to one another in a suitable manner, for example by plugging, screwing or welding. They are each made from suitable metal profiles, for example.

On the upper cross member 34a, two combinations of a support component 44a, 44c and a first primary fixing component 46a, 46c are arranged in the direction of the first shaft wall 18. In the Fig.1 only a combination of support component 44a and first primary fixation component 46a can be seen. Fig.2 shows both combinations. On the middle cross member 34b, two combinations of a support component 44b and a second primary fixing component 46b are arranged in the direction of the first shaft wall 18. In the Fig.1 and 2 only a combination of support component 44b and second primary fixation component 46b can be seen.

The support components 44a, 44b, 44c and the primary fixing components 46a, 46b, 46c are arranged such that they each form corners of a rectangle whose edges run in the displacement direction 27 and in a transverse direction perpendicular to the displacement direction 27 and the fixing direction 40, wherein the primary fixing components 46a, 46b, 46c are arranged further outwards in the displacement direction 27 than the support components 44a, 44b, 44c.

The primary fixing components 46a, 46b, 46c each have an arm 53a53b, which is connected to the respective cross member 34a, 34b. A primary support element in the form of a rubber buffer 55a, 55b, 55c is arranged on the arms 53a, 53b in the direction of the first shaft wall 18.

The arms 53a of the two upper, first primary fixing components 46a, 46c are connected to the upper Crossbar 34a. The arms 53a and thus the two first primary fixing components 46a, 46c are thus arranged pivotably relative to the upper crossbar 34a and thus relative to the base frame 30. The first primary fixing components 46a, 46c can thus assume a working position and a transport position, whereby in the Fig.1 the working position is shown. In the working position, the arms 53a extend from the upper cross member 34a and thus from the base frame 30 in the direction of extension and thus in the direction of displacement 27 upwards. In order to Fig.3 In order to set the transport position of the first primary fixing components 46a, 46c shown, the arms 53a and thus the first primary fixing components 46a, 46c can be pivoted downwards about the pivot axis mentioned and thus displaced in the direction of the base frame 30. The transport position of the first primary fixing components 46a, 46c is referred to in connection with the Fig.3 discussed in more detail.

The arms 53b of the two lower, second primary fixing components 46b are fixedly and thus immovably connected to the central cross member 34b and thus to the base frame 30. No part of the second primary fixing components 46b protrudes beyond the base frame 30 in the direction of extension and thus in the direction of displacement 27.

The rubber buffers 55a, 55b, 55c are arranged via the arms 53a, 53b on the respective crossbar 34a, 34b and thus on the base frame 30. In the case of the second primary fixing components 46b, this connection never allows any movement in the fixing direction 40 relative to the base frame 30 and in the case of the first primary fixing components 46a, 46c, at least in their working position, it does not allow any movement.

Each support element 44a, 44b, 44c has a roller 48a, 48b, 48c that can rotate about an axis (not shown) and can roll along the first shaft wall 18 in the direction of displacement 27. The axes of the rollers 48a, 48b, 48c are each attached to the arm 53a, 53b of the associated primary fixing component 46a, 46b, 46c via a holder 50 so that they can move in the fixing direction 40. The holders 50 can each have a corresponding slot (not shown) for this purpose. Energy storage devices in the form of coil springs 52 are arranged between the arms 53a, 53b and the respective axis of the rollers 48a, 48b, 48c in such a way that they support the rollers 48a, 48b, 48c against the first shaft wall 18 so that the rollers 48a, 48b, 48c and thus the support components 44a, 44b, 44c each rest against or are supported on the first shaft wall 18 via a support surface 54a, 54b, 54c.

A secondary fixing component 56 is arranged on the middle part 32 of the base frame 30 in the direction of the second shaft wall 20. An actuating stamp 58 running in the fixing direction 40 is mounted in the middle part 32 and protrudes from the middle part 32 in the direction of the second shaft wall 20. The actuating stamp 58 can be displaced in the fixing direction 40 by means of two actuators in the form of electric spindle drives 60, i.e. can be extended from the middle part 32 and retracted into the middle part 32. The actuating stamp 58 is connected to a secondary contact element 64 elongated in the displacement direction 27 via an intermediate piece 62, which also runs in the fixing direction 40 and is thus arranged in alignment with the actuating stamp 58, and a holding plate 63. The actuating stamp 58 is inserted into the intermediate piece 62 and can be secured in various positions relative to the intermediate piece 62 with a bolt (not shown). This allows a distance of the secondary contact element 64 to the middle part 32 and thus to the base frame 30 in the fixing direction 40 to be changed independently of the spindle drives 60 of the secondary fixing component 56.

The secondary support element 64 is designed in several parts. A middle piece 66 can be firmly connected to the intermediate piece 62 via the holding plate 63. It is also possible for the middle piece 66 to be detached from the holding plate 63, so that the secondary support element 64 can be completely dismantled. The middle piece 66 is connected to an end piece 68 at the top and bottom in the direction of displacement 27, which can be easily assembled and dismantled.

In the Fig.1 and 2 the four support components 44a, 44b, 44c are in the displacement position. The rollers 48a, 48b, 48c protrude beyond the primary fixing components 46a, 46b, 46c in the direction of the first shaft wall 18. In addition, the secondary contact element 64 of the secondary fixing component 56 is in the displacement position. The secondary contact element 64 therefore does not rest against the second shaft wall 20, but is at a distance from the second shaft wall 20 in the fixing direction 40.

In this state of the assembly frame 24 and thus of the assembly device 26, it can be moved in the displacement direction 27 in the elevator shaft 16 by means of the winch 12 and the cable 22 and thus positioned at different heights. The assembly frame 24 is supported on the first shaft wall 18 via the support surfaces 54a, 54b, 54c of the rollers 48a, 48b, 48c. The rollers 48a, 48b, 48c roll on the first shaft wall 18.

In order to fix the mounting frame 24 and thus the mounting device 26 in the elevator shaft 16, the secondary support element 64 of the secondary fixing component 56 is displaced by means of the two spindle drives 60 in the direction of the second shaft wall 20, i.e. outward away from the base frame 30. As long as the secondary support element 64 has not reached the second shaft wall 20, the support elements 44a, 44b, 44c remain in the position shown in the Fig.1 and 2 shown displacement position. When the secondary support element 64 rests against the second shaft wall 20 and the actuating piston 58 is extended further from the middle part 32, the entire base frame 30 with all parts immovably arranged on it is displaced in the direction of the first shaft wall 18. The coil springs 52 of the support elements 44a, 44b, 44c are then compressed until the primary fixing components 46a, 46b, 46c rest against the first shaft wall 18 via the rubber buffers 55a, 55b, 55c. The assembly frame 24 is thus caulked or braced between the first shaft wall 18 and the second shaft wall 20 and thus fixed.

In the Fig.1 and 2 the mounting frame 24 is shown in a working state. In this working state it is arranged in the shaft 16 and enables installation in the shaft. The working state is characterized by the fact that

If the mounting frame 24 and thus the mounting device 26 are to be transported, for example to another shaft, then the mounting frame 24 is brought into a transport state which is Fig.3 The transport condition is characterized by the fact that

• the first primary fixing components 46a, 46c are in their transport position, i.e. the arms 53a are pivoted downwards towards the base frame 30, so that no part of the first primary fixing components 46a, 46c protrudes beyond the base frame 30 in the direction of extension,
• the base frame 30 is in its transport position, the two parts 49, 51 of the longitudinal beam 42 are pushed into each other as far as possible,
• the two parts 36a, 38a; 36b, 38b; 36c, 38c of the cross members 34a, 34b, 34c are pushed into each other as far as possible,
• the actuating plunger 58 and the intermediate piece 62 of the secondary fixing component 56 are pushed into each other as far as possible and
• the secondary contact element 64 of the secondary fixing component 56 is completely dismantled.

In order to move the base frame 30 from its working position to its transport position and vice versa, i.e. to push the two parts 49, 51 of the longitudinal beam 42 into one another or to pull them apart, an adjustment device in the form of a crank 70 is arranged on the first part 49 of the longitudinal beam 42, which interacts with Bowden cables (not shown) in the two parts 49, 51 of the longitudinal beam 42. By turning this crank 70, the two parts 49, 51 can be pushed into one another and pulled apart. The crank 70 is arranged in such a way that it can also be operated from outside the shaft 16 when the assembly frame 24 is in the shaft 16.

The extension of the assembly frame 24 in the extension direction and thus in the displacement direction 27 in the transport state is significantly smaller than in the working state. This reduction results on the one hand from the change of the first primary fixing components 46a, 46c from their working position to their transport position and on the other hand from the change of the base frame 30 from its working position to its transport position.

In addition, the extension of the assembly frame 24 in the fixing direction 40 is significantly smaller in the transport state than in the working state. This reduction results from the sliding of the associated parts 36a, 38a; 36b, 38b; 36c, 38c of the cross members 34a, 34b, 34c into one another, the sliding of the actuating plunger 58 and the intermediate piece 62s of the secondary fixing component 56 into one another and the dismantling of the secondary contact element 64 of the secondary fixing component 56.

Furthermore, it should be noted that features or steps that have been described with reference to one of the above embodiments can also be used in combination with other features or steps of other embodiments described above.
