Description

[0001] The present invention relates to an assembly platform provided for use in the construction of a power pole having a plurality of mast sections.

[0002] The technical field of the present invention relates to work platforms for constructing power poles. In practice, it is known to use telescopic work platforms mounted on trucks and thus transportable. Constructing a power pole requires the use of at least four truck-mounted telescopic work platforms. The telescopic design makes it possible to raise the work platform to the required height.

[0003] Power line pylons are used in practice for overhead power line construction. A power line pylon can therefore also be called a high-voltage pylon or overhead line tower and is ultimately a structure for attaching or suspending at least one overhead electrical line. Typically, a number of overhead lines are attached to a single power line pylon. The power line pylon supports these overhead lines.

[0004] Power line pylons within the meaning of the present invention are support pylons, guyed pylons, and / or branch pylons, particularly for high- and extra-high-voltage lines—that is, especially for voltages greater than 50 kV. Such pylons are generally designed as steel lattice pylons. These pylons, which can also be referred to as lattice towers, are hereinafter referred to as power line pylons. In practice, medium-voltage lines (1 to 50 kV) are often run parallel to the high- and extra-high-voltage lines on the power line pylon. The parallel routing of high- and extra-high-voltage lines with different voltages, such as 380 kV, 220 kV, and 110 kV lines, on a single power line pylon is also known.

[0005] Power poles within the meaning of the present inventions also include power poles for high-voltage direct current transmission.

[0006] Electricity pylons can be distinguished, particularly in their design, between single-level and Danube pylons. All designs feature a vertical section and horizontal sections extending from it.

[0007] Depending on the specific installation situation and also on the electrical voltage of the overhead lines to be attached to the pylon, various types of pylons are known in practice. As a rule, pylons are made of steel or of a steel structure. The present invention relates in particular to pylons for high-voltage and extra-high-voltage lines – that is, for overhead lines with a voltage greater than 30 kV, and especially greater than 50 kV.

[0008] The construction of power lines, formed by a multitude of power pylons and overhead lines attached to them, is crucial in order to transport electricity from its point of origin to the consumer.

[0009] For the assembly of power poles, it is known to deliver the power poles in individual parts or sections and provide them at the installation site. It is also known that individual sections of the power pole are pre-assembled, forming so-called pole sections. These pole sections can be stacked on top of each other to form the vertical part (in relation to the base of the power pole). In this context, the pole sections have a number of crossbeams and corner posts and are primarily made of steel. If required, a pole section can also have horizontal braces that connect the corner posts. To install individual pole sections, installers must, after securing the first pole section to the ground, place and assemble or firmly connect the subsequent pole sections onto the previous one. For this purpose, the respective installers must be positioned at the appropriate working position or pole section height.In practice, it is common to use truck-mounted telescopic boom lifts for this purpose, which can be extended to the required heights via a telescopic arm. However, such telescopic boom lifts have a limited reach, making it sometimes impossible to extend the uppermost sections of the pylon using one such platform. Furthermore, securing a single pylon section typically requires several truck-mounted telescopic boom lifts, necessitating the availability of multiple trucks. Depending on the installation situation, it may not be feasible to position numerous trucks around the already installed section of the power pole. This method of installation is particularly unsafe in areas with rocky terrain.

[0010] It is also known that installers sometimes climb onto already installed mast sections to attach new sections and carry out the installation directly on site – secured only to the existing mast section. However, this procedure poses significant risks and a high susceptibility to accidents. Should an installer fall from this height or be injured while working, such an accident can often be fatal. Therefore, climbing onto mast sections to attach them is a dangerous installation technique.

[0011] It should also be taken into account that attaching a mast section to be mounted does not require just one installer, but usually eight installers working on different corner joints of the mast section. This parallel work is necessary to ensure the correct positioning of the mast section and its horizontal alignment for installation.

[0012] The object of the present invention is now to avoid or at least substantially reduce the aforementioned disadvantages of the prior art.

[0013] The aforementioned problem is solved by an assembly platform with the features of claim 1.

[0014] Advantageous further training is the subject of the sub-claims.

[0015] The assembly platform according to the invention is intended for use in the construction of a power pole comprising a plurality of mast sections. In this context, the assembly platform serves to attach a mast section to be added to an already assembled mast section. The assembly platform has at least four platform segments, an adjusting device for adjusting the platform segments relative to each other to change the opening cross-section enclosed by the platform segments, and a fastening device for attaching the assembly platform to the already assembled mast section.

[0016] The present invention provides, for the first time, an assembly platform that can be attached to an already installed mast section. This eliminates the need to maintain a large number of truck-mounted telescopic work platforms, each of which lifts an individual work platform to the respective position.

[0017] The assembly platform can be lifted onto the already installed mast section using a crane and then secured to the section via the fastening device. The crane is then no longer needed to hold the assembly platform in its position. Specifically, the lifting equipment and / or cables connecting the crane and the assembly platform can be detached after the platform has been installed and secured to the existing mast section. The assembly platform can thus be firmly connected to the already installed section of the power line tower, ensuring a high level of safety for the installers when mounting another mast section.

[0018] This allows, in particular, the fitters to move along the stage segments, especially while secured to them. The fitters can be secured, in particular, by a safety system arranged around the entire perimeter of the stage segments, which includes, in particular, safety rails attached to the stage segments.

[0019] In practice, it is only known that fitters can only be secured to the already assembled mast section and must move along the individual struts of the mast section at great risk. According to the invention, occupational safety for fitters can also be increased in difficult-to-access terrain, in particular by eliminating the need for fitters to climb onto or along the mast section.

[0020] When using truck-mounted telescopic work platforms, access to the already installed mast section is often insufficient, significantly complicating the installation of the next mast section due to the large distance between the work platform and the already installed mast section. According to the invention, this distance can now be circumvented by attaching the work platform directly to the last installed mast section.

[0021] This significantly reduces the costs of erecting a power pole and also leads to a significant increase in occupational safety. The assembly platform according to the invention can prevent or at least significantly reduce potential fatal workplace accidents. The platform provides installers with a working level that can be individually attached to the power pole.

[0022] The design of the assembly platform according to the invention enables a more ergonomic working method for the fitters, particularly compared to a "climbing" fitter, taking the given circumstances into account. This can reduce work absences of the fitters due to physical strain.

[0023] Furthermore, the assembly platform simplifies the attachment of the mast section to be installed. A technician standing on the platform segment has significantly more freedom of movement than technicians who have to move or remain on or near an already installed mast section. At the same time, the invention also provides a place to set down tools or materials on the platform segments. This increases the comfort for technicians during the installation of a power pole and ultimately leads to faster assembly, as the increased comfort also speeds up the individual assembly steps. A technician can move along at least one platform segment, eliminating the need for cumbersome climbing and / or repositioning using a truck-mounted telescopic work platform, which significantly simplifies the installation process.

[0024] Furthermore, the fastening device used in the assembly platform according to the invention allows the platform to be used for erecting multiple power poles and is therefore particularly suitable for multiple uses. This offers the particular advantage of enabling long-term use for erecting power poles with the assembly platform according to the invention.

[0025] The adjustable opening cross-section between the platform segments now allows the mounting platform to surround all four sides of a mast section. With mast sections, the enclosed cross-section changes with the height of the mast section. For example, several stacked mast sections of a power pole taper upwards. The adjustable opening cross-section allows the mounting platform to adapt to different mast sections. This ensures the smallest possible horizontal distance between the mast section and the mounting platform at all times. Furthermore, the same mounting platform can be used to secure multiple mast sections that differ in their external cross-section or that have different external cross-sections along their respective heights, particularly so that the mast section tapers upwards or downwards.It is designed to taper away from the substrate when mounted.

[0026] Furthermore, the adjusting device allows the enclosed opening cross-section of the platform segments to be changed as needed, even when the platform is already mounted on the mast section, and particularly when connected to the already mounted mast section. Such a change is necessary, for example, when the distance between the mast section and the assembly platform needs to be reduced.

[0027] Furthermore, a further advantage of the assembly platform according to the invention is that additional components, tools, and / or fasteners, such as screws, nuts, etc., for attaching the two adjacent mast sections to one another can also be stored on the platform segments. For example, it is known that so-called gusset plates are used for bolting the mast sections together. These gusset plates are separate components and are ultimately connected by friction to both the already mounted mast section and the mast section to be installed. These gusset plates can be arranged, in particular, on or attached to the platform segments. In practice, it has generally been necessary to pre-assemble these gusset plates on the mast section to be installed, thus requiring time-consuming realignment and adjustment of the gusset plates during assembly.

[0028] Advantageously, the assembly platform can also be used for erecting power pylons in hard-to-reach areas. For example, if a power pylon is being erected in mountainous terrain, it is usually not possible to position several truck-mounted telescopic work platforms around the pylon. In this case, the assembly platform can be lifted to the installation site by a single crane and securely attached to the already erected pylon section using the fastening device. The helicopter is then used primarily for the initial placement of the assembly platform onto the already erected pylon section.Once the mast section to be installed has also been firmly mounted, the assembly platform can either be lifted again using external lifting equipment, such as a crane and / or a lifting device provided on the assembly platform itself, and attached, for example, to the installed, already mounted mast section and used again for the installation of another mast section.

[0029] A further advantage of the assembly platform according to the invention is that only one crane is sufficient for the safe erection of a power pole. In the prior art, the use of assembly platforms for erecting a power pole required at least one crane with appropriate lifting equipment and up to four truck-mounted telescopic work platforms. According to the invention, only one crane with appropriate lifting equipment is now sufficient. This crane with appropriate lifting equipment is required to position the pole section, which can also be done, if necessary, using a helicopter with lifting equipment attached to it.The same crane, or another crane, can be used to raise the assembly platform to the appropriate working height before the mast section is installed. The assembly platform can then be securely attached to the already installed mast section via the fastening device, allowing the connection to this crane to be released if necessary. This crane can then subsequently be used to install the mast section.

[0030] The aforementioned option makes it possible to safely erect a power pole even at installation sites on steep terrain that do not provide sufficient space for the arrangement of several cranes.

[0031] Furthermore, the reduced number of truck-mounted telescopic work platforms required significantly reduces the assembly costs for a power pole, while at the same time increasing occupational safety for the fitters.

[0032] In practice, it is common to install a support beam inside the power pole. However, this support beam only provides adequate, and sometimes inadequate, access to the areas to be bolted between the already installed pole section and the section to be added. Furthermore, its height is limited for structural reasons, and it is comparatively expensive. The assembly platform offers an advantageous alternative that can ensure cost-effective construction of the power pole.

[0033] The fastening of mast sections to one another can also be referred to as "staking" and / or mast joining in the sense of the present invention.

[0034] In summary, it can be concluded that the assembly platform according to the invention can serve as a standing surface for the fitters during the construction of the power pole and as a storage area for materials required during the work. Due to the mobile deployment of the assembly platform and the variable opening cross-section, the assembly platform can be used for the construction of different power poles and enables a high degree of flexibility and long-term, repeated use of the assembly platform according to the invention.

[0035] It is particularly advantageous if the floor of the stage segments is closed, a close-meshed grid, level, and / or slip-resistant to increase stability. The floor of the stage segment is significantly more stable and provides a secure base for the installer, especially compared to the struts of a mast section.

[0036] Furthermore, each stage segment, or at least one stage segment, can have a guardrail to protect fitters from falls and objects from falling out. In particular, all stage segments have a surrounding, preferably all-around, guardrail. The guardrail can have a height of at least 1 m and, in particular, be firmly attached to the floor of the stage segment. The guardrail can, in particular, enclose the floor and project beyond the floor section.

[0037] Furthermore, the platform segments can form a closed platform frame to enclose the already assembled mast section. This platform frame can include, in particular, the floor and the guardrails of the platform segments. Specifically, all platform segments are interconnected, thus forming the platform frame. This increases the stability of the assembly platform in its assembled state, as the platform segments can ultimately be supported both by the already assembled mast section and by each other, thereby providing a stable base and working platform for the installers.

[0038] In a particularly preferred embodiment of the present invention, the fastening device is designed for fastening, preferably for a friction-fit and / or form-fit connection, to the corner posts of the power pole.

[0039] In particular, the power pole has four corner posts, which are arranged at an angle to the ground, so that the power pole preferably tapers towards the top. The corner posts are designed as angle profiles, and the fastening device is designed to engage behind these angle profile corner posts. The corner posts enable the weight of the assembly platform to be transferred into the already assembled pole section and provide secure support for the assembly platform.

[0040] In a further, particularly alternative, embodiment, it is specifically provided that the fastening device is designed for suspension on at least one strut of the already assembled mast section. In particular, in this further embodiment, the fastening device is designed for suspension on a cross strut and / or horizontal strut.

[0041] In particular, a cross brace or a horizontal brace connects two opposing corner posts of the mast section. A mast section can have corner posts and cross braces. In further embodiments, horizontal braces extending at least substantially horizontally to the ground can be provided, which can also connect two opposing corner posts. The cross braces can be arranged transversely or at an angle to the corner posts and / or horizontal braces.

[0042] Depending on the specific design of the power pole, different cross and / or horizontal braces or struts may be used. In particular, two cross braces may intersect, each connecting two corner posts. It may also be the case that multiple cross braces connect the corner posts, especially to increase stability. These cross braces can also be referred to as diagonal braces.

[0043] The fastening option via the fastening device to the corner posts and / or struts of the already installed mast section enables, according to the invention, a secure yet detachable arrangement and mounting of the assembly platform on the already attached mast section, thus ensuring the advantages discussed at the outset. Due to the connection between the fastening device and the already installed mast section, an external support for the assembly platform, for example via a crane, is no longer strictly necessary. A crane and / or an external lifting device is only used as needed to raise and / or lower the assembly platform.

[0044] As an alternative to a crane or external lifting equipment for the vertical movement of the assembly platform, it is also possible to have a lifting device with lifting elements integrated into the platform itself. The lifting device can be designed such that, after the installation of a mast section, particularly at its upper end, fastening elements of the lifting device, such as hooks or similar, are attached. These elements interact with at least one pulling device, such as a winch, via appropriate traction elements like ropes or chains. By winding up the ropes, the platform can then be raised or, if necessary, lowered. With this design, cranes and helicopters can be completely eliminated. Ultimately, it is a self-propelled assembly platform.

[0045] The fastening device can be manually connected to the already installed mast section by the fitters if necessary, particularly while the assembly platform is still connected to the crane. Once the fastening device is securely connected to the already installed mast section, the connection to the crane and / or the external lifting equipment can then be disconnected.

[0046] In a further particularly preferred embodiment of the present invention, the fastening device comprises at least one fastening element, in particular at least one fastening element per stage segment. In particular, several fastening elements per stage segment may also be provided as required. The fastening element is preferably arranged both on the assembly platform or on the stage segments and on the corner posts, preferably in such a way that a clamping and / or friction-fit connection to the corner posts can be ensured.

[0047] The fastening device particularly preferably interacts with the stage segment associated with the fastening device, in particular wherein the fastening device can be detachably connected to the already mounted mast section by friction fit and / or form fit.

[0048] The fastening devices are primarily intended for direct attachment to the already installed masthead. A fastening device can be designed as a hook, locking element, anchor, chain, rope, turnbuckle, screw connector, chain connector, clamp, and / or a combination of the aforementioned connecting devices. For example, a chain and / or rope can be connected to a turnbuckle, chain connector, clamp (especially a wire rope clamp), or the like. A wire section can be used as the rope. Rope thimbles can also be provided to guide the rope, particularly for fiber ropes or steel ropes. In any case, the fastening devices are designed to ensure secure attachment.

[0049] The shape of the fastening device is preferably adapted so that secure mounting on the corner posts and / or struts of the already mounted mast section can take place.

[0050] Preferably, the respective fastening device is detachably connectable to the already mounted mast section by friction and / or positive locking. A clamping connection between the stage segment and the already mounted mast section can also be achieved via the fastening device. In particular, the fastening device is connected to, or can be connected to, a corner post of the already mounted mast section of the power pole by friction and / or positive locking.

[0051] The corner posts can then serve, for example, for the installation of fastening devices such as chains, wire ropes, fiber ropes, clamps, and / or hooks. Furthermore, it may be provided that, for example, fastening devices are provided for installation on the corner posts, and additional fastening devices are provided that allow for installation and attachment to horizontal and / or transverse struts.

[0052] In a further preferred embodiment of the invention, each stage segment is slidably mounted at a first end face on a longitudinal side of an adjacent stage segment. This allows the stage segments to be adjusted relative to changes in the enclosed opening cross-section. The stage segments can be elongated and preferably have two end faces. One end face, namely the first end face, can then be slidably mounted on a longitudinal side, particularly an inner longitudinal side, of an adjacent stage segment. In particular, all stage segments have a first end face that is mounted or attached to a longitudinal side, particularly an inner longitudinal side, of an adjacent stage segment, thereby forming a closed stage frame.

[0053] Preferably, the positioning device has longitudinal guide rails arranged on the stage segments. The stage segment can be movably mounted along the guide rail, particularly at its first end face. Thus, the direction of movement of a stage segment to change the enclosed opening cross-section can be determined by the interaction between the guide rails and the first end face. The guide rails can provide secure support or mounting for the end face, which can be moved along this longitudinal side in and / or on and / or along the guide rail. In particular, the guide rails run along the inner longitudinal sides of the stage segments.The guide rails can be attached to at least one lower edge of the longitudinal side, for example, the bottom edge, or several guide rails can be provided on one longitudinal side for positioning the first end face of the adjacent stage segment. The end faces ultimately enable, in particular, a relative displacement or adjustment of the stage segments relative to each other.

[0054] In a further particularly preferred embodiment, the adjusting device includes a cable pulley system for adjusting the stage segments relative to one another. The cable pulley system can comprise one or more cables as required. In particular, the cable pulley system can be designed such that a change in the opening cross-section can be ensured even when the stage is already mounted on the mast section. The cable pulley system can be operated, in particular, by motor or manually. The cable pulley system can, in particular, connect all stage segments to one another and thus cause the stage segments to be moved relative to each other. The cable pulley system can also, if required, adjust all stage segments simultaneously. Thus, the cable pulley system offers user-friendly adjustability of the opening cross-section.

[0055] Preferably, the cable system comprises at least one outer cable running along the outer longitudinal sides of the stage segments. Preferably, the outer cable can additionally wrap around and / or enclose further end faces opposite the respective first end face. Alternatively or additionally, the cable system can be designed such that retracting the outer cable increases the opening cross-section enclosed between the stage segments. The outer cable ultimately enables a desired increase in the opening cross-section, particularly when the outer cable is actuated accordingly, especially manually and / or by motor. Actuation of the outer cable can preferably be carried out by the fitters standing on the assembly platform.

[0056] External pulleys can be provided to guide the outer rope. Accordingly, the rope pulley system can have external pulleys for deflecting the outer rope. In particular, at least one external pulley can be arranged on the first end face and / or at least one, preferably two, external pulleys or one external pulley can be arranged on the other end face of the stage segment. The external pulleys ensure that the outer rope can be guided without snagging or entanglement when transitioning from one stage segment to another. The pulleys, in particular, enable the rope to run and be guided smoothly when it is operated.

[0057] Furthermore, the cable system can include an inner cable running along the inner longitudinal sides of the stage segments. The inner cable can be provided as an alternative or in addition to the outer cable. Specifically, the inner cable is routed around and / or adjacent to the first end faces of the stage segments.

[0058] Alternatively or additionally, the cable pull system can be designed in such a way that retracting the inner cable reduces the opening cross-section enclosed between the stage segments.

[0059] Accordingly, in particular, the enclosed opening cross-section can be increased by pulling in the outer rope, and the enclosed opening cross-section can be reduced by pulling in the inner rope.

[0060] In particular, the inner rope can be guided on and / or in the guide rails, or in at least one guide rail per platform segment. The inner rope can also be operated by the fitters on the assembly platform while in operation, in particular manually and / or with a motor.

[0061] In a further preferred embodiment of the invention, the cable system has internal pulleys for deflecting the inner cable. The internal pulleys, or at least one internal pulley, can be arranged on the first end face of a stage segment. The internal pulleys can also ensure safe guidance of the inner cable during retraction.

[0062] In this context, it is understood that when the outer rope is retracted, the inner rope is extended as needed, and vice versa. Actuation of the outer rope can therefore also lead to actuation of the inner rope, and vice versa.

[0063] In a further preferred embodiment, the stage segment comprises an elongated lower floor section and side sections, in particular fall protection grid side sections, projecting upwards from the floor section to both longitudinal sides.

[0064] Preferably, the base section, which is rectangular in plan view, has two longer longitudinal sides and two shorter end faces. The barrier can encompass the side sections and, in particular, extend along the longitudinal sides and the end faces. The barrier can, in particular, project from the base section.

[0065] The floor section can preferably form the floor of the stage segments and may be designed as a closed surface and / or a close-meshed grid. In any case, the floor section is designed in such a way that the installers have a secure footing on it.

[0066] The side sections can extend in particular along the entire longitudinal side of the stage segments and have a height of at least 1 m and preferably provide fall protection for the fitters.

[0067] In a further preferred embodiment of the present invention, the cable system comprises at least one winch, in particular a hand winch, for operating the respective cable, in particular for retracting or releasing the respective cable, and in particular wherein the winch is arranged on at least one stage segment. Alternatively or additionally, it may be provided that an electric cable winch is used.

[0068] Accordingly, a motor, in particular an electric winch, can be provided for the motorized operation of both the inner and outer cables as needed. The electric winch can therefore be operated by an electric motor. The electric winch can then be used to extend or retract either the outer or inner cable as required, thus operating the cable system.

[0069] In a further preferred embodiment of the present invention, a fall protection unit projecting upwards from the floor section is arranged on the far end of the stage segment. The fall protection unit is particularly designed as a safety barrier. The fall protection unit can also be part of the guardrail for the stage segments. The guardrail, as well as the fall protection unit, ensures that a person on the stage segments is prevented from falling. This thus leads to an increase in workplace safety.

[0070] Furthermore, a support frame can be provided on the first end face for adjusting the platform segments relative to each other and / or for attaching an external hoist to lift the assembly platform. The support frame can also be part of the guardrail or provided separately. In particular, the support frame projects upwards from the side section. The support frame can be equipped with access points for an external hoist system, which can be operated, for example, by a crane. The support frame can be provided independently of the fastening device. In further embodiments, the fastening device can also be arranged at least partially on the support frame.

[0071] The support frame also leads to increased occupational safety and, in particular, enables positioning in or on the guide rails on the longitudinal sides of the stage segment, thus ensuring relative adjustment of the stage segments to each other.

[0072] Furthermore, the support frame also allows for the installation of an external motorized hoist, which makes it possible to raise the assembly platform to the required working height.

[0073] The guardrail can be formed in particular by the fall protection unit, the side sections, and / or the supporting frame. The guardrail can at least substantially prevent an unwanted fall of persons on the assembly platform.

[0074] Preferably, the fastening means are connected to the support frame and / or to a side section. The arrangement of the fastening means is determined in particular by the chosen fastening method between the stage segment and the already mounted mast section. If necessary, the fastening means can also be adjusted on the side sections and / or on the support frame, so that a customized arrangement on the already mounted mast section or on the corresponding struts of the already mounted mast section can be achieved.

[0075] Finally, in another preferred embodiment, a barrier is provided on the support frame and / or on the first end unit to prevent access to the stage segment adjacent to the support frame. This barrier can ensure, in particular, that when the stage segments are moved relative to each other as required, persons on the assembly platform are not permitted to enter the area of ​​the stage segment that protrudes from the immediately adjacent stage segment.

[0076] This also prevents the entire assembly platform from being circumnavigated. Ultimately, only one technician per platform segment can work on that segment and can only move along that single segment – ​​specifically between the first end of the platform segment and the barrier.

[0077] In particular, the barrier connects the two side sections of the stage segment and / or spans them.

[0078] The barrier can be provided in addition to the guardrail of a stage segment. Accordingly, the stage segment can have a guardrail projecting from the floor on all outer sides, specifically two side sections extending along the longitudinal sides of the stage segment, the fall protection unit, and the supporting frame. The barrier, provided in addition to the guardrail, ensures that the installer can only access the section of the stage segment intended for their use.

[0079] In a preferred embodiment of the invention, the fastening means comprises at least one first frictional locking element, in particular two first frictional locking elements, and at least one second frictional locking element, in particular two second frictional locking elements. When the mounting platform is fastened, the second frictional locking element can interact frictionally with each of the first frictional locking elements, in particular wherein each first frictional locking element is also provided with a second frictional locking element.

[0080] Functionally, the friction elements can be compared to brake pads of a disc brake, which, through frictional forces, can brake the downward movement induced by the weight of the assembly platform, preferably to a standstill.

[0081] The friction elements can act on the corner posts, particularly on opposite sides of the corner post. The corner post is preferably designed as an angle profile. In this embodiment, it is preferred that a first and a second friction element bear against each leg of the angle profile corner post. In this way, secure support of the assembly platform can be achieved, whereby the weight of the assembly platform can be transferred into the sufficiently robust corner posts.

[0082] Preferably, the corner post of the already assembled mast section is positioned between the first and second friction locking elements. Consequently, the corner post can be clamped between the friction locking elements, thereby fixing the assembly platform, since the platform segments can in turn interact with the first friction locking elements.

[0083] In particular, the first and second frictional elements can act on the corner post in at least substantially opposite directions when fastened, especially like brake pads of a disc brake.

[0084] A joint mechanism can be provided to actuate the fastening device, connecting the friction elements to one another. Furthermore, the joint mechanism can be designed to allow the first and second friction elements to interact. In particular, the joint mechanism can be rigidly connected to the stage segment, especially the support frame, and / or rigidly connected to the first and / or second friction element.

[0085] In a particularly preferred embodiment, the joint mechanism, when fastened, is rigidly connected, at least at least at one bearing point, to the platform segment, in particular the support frame, and to the first and second frictional elements. Accordingly, the joint mechanism can transmit the holding force from the frictional elements to the assembly platform, and similarly, the weight of the assembly platform can be transferred via the joint mechanism into the frictional elements and subsequently into the corner posts when fastened.

[0086] The articulated design of the joint mechanism allows for selective loosening and tightening of the fastener. Loosening is necessary for the desired movement of the assembly platform, for example, when it is to be raised or lowered by a crane. In the desired working position, the assembly platform can then be secured to the mast section by tightening the joint mechanism, which is achieved simply by lowering the platform. When raising or lowering the assembly platform, the fastener can either be completely removed from the corner post or fixed in a sliding position relative to the corner post using a locking device. Even in the sliding position, the corner post can be positioned between the first and second frictional locking elements, and, in particular, can be spaced apart from them by a clear distance, which is not possible when the platform is fastened.

[0087] Preferably, the joint mechanism comprises at least one joint via which an adjustment of the friction elements relative to each other can be ensured.

[0088] In particular, the joint mechanism is designed such that the two friction elements are adjustable relative to each other and / or can be aligned with each other. Alternatively or additionally, the joint mechanism may have a first lever that can be connected, in particular rigidly, to the first and / or the second friction element and a second lever that can be connected, in particular rigidly, to the stage segment, in particular the support frame, in particular wherein the levers are connected to each other via a pivot point.

[0089] The first lever is, in particular, preferably via at least one pin, rigidly connected at individual bearing points to the first and second frictional elements. The second lever can be rigidly connected to the stage segment, in particular to a stage segment support element, preferably a strut of the support frame. Because both levers are rigidly but movably connected to each other at the pivot point, the necessary relative movement between the frictional elements and the stage segments for fastening can be achieved.

[0090] In particular, the first friction-locking element has a stop area that rests against the corner post of the already assembled mast section, especially on the inner side of the corner post designed as an angle profile, facing away from the assembly platform, and a connecting section that projects from the stop area to the platform segment, especially to the support frame. The connecting section ensures that the gap between the corner post and the platform segment can be bridged. The stop area and the connecting section can be firmly, preferably rigidly, connected to each other.

[0091] Preferably, the first lever is rigidly connected, in particular by a material connection and / or rigidly, preferably via a pin, to the stop area of ​​the first friction element at a first bearing point of the connecting joint mechanism. The connecting section of the first friction element can in turn have a guide area, in particular an elongated hole, for guiding a pin of the second lever which engages in the guide area and is rigidly connected, in particular by a material connection and / or rigidly, to the stage segment, preferably the support frame and / or a stage segment support element, in particular the support frame. The stop area and the connecting section thus ensure the connection to the stage segment via the joint mechanism.

[0092] Furthermore, in another preferred embodiment, the second frictional locking element is rigidly connected to the first lever at a second bearing point, in particular by a rigid and / or material-fit connection. Preferably, for the purpose of securing the mounting platform, the second frictional locking element is mounted so as to be movable relative to the first frictional locking element and / or to the stop area of ​​the first frictional locking element.

[0093] For the second frictional element(s) of a fastening device, an angle profile may be provided, which is designed, in particular, at least substantially corresponding to the outer shape of the outside of the corner pillar facing the stage segments and, in particular, rests directly against the outside of the corner pillar. The second frictional elements may be firmly connected to the angle profile, in particular integrally and / or by force-fit and / or by material bond.

[0094] In particular, two second frictional locking elements of a fastening device can be firmly connected to the angle profile directly adjacent to the outside of the corner pillar facing the assembly platform.

[0095] The angle profile allows for easy adjustment of the secondary fasteners to be attached to the corner posts. Furthermore, the angle profile improves the absorption of forces transferred to the masthead.

[0096] Furthermore, in another preferred embodiment, a stop plate of the fastening element can be provided between the stop area and the inside of the corner post, and this stop plate is particularly firmly connected to the stop area. Specifically, the fastening element has two stop plates, one for each stop area, with the stop plates bearing directly against different legs of the corner profile, which is designed as an angle profile. The stop plate can be formed integrally with the stop area and / or be connected to it by a material bond, a force bond, and / or a form-fit. The stop plate also facilitates, in particular, easy adjustment or centering of the stop area on the corner post and can ensure improved force transmission into the corner post.

[0097] Furthermore, it is expressly pointed out that all the aforementioned and subsequent intervals include all intermediate intervals and individual values ​​contained therein, and that these intermediate intervals and individual values ​​are to be regarded as essential to the invention, even if these intermediate intervals or individual values ​​are not specifically specified in detail.

[0100] The Fig. 1A Figure 1 shows an assembly platform 1 intended for use in the construction of a power pole 3 having a plurality of mast sections 2a, 2b. Individual steps for the construction of a power pole 3, in particular for the construction of the at least substantially vertical section of the power pole 3, are shown in the following. Fig. 4A bis 4C schematically represented. Fig. 4A bis 4C Figure 1 shows the power pole 3 to be erected, which is intended for the arrangement of overhead power lines or the like. A power pole 3 is erected by stacking or stacking individual pole sections 2. In this process, a pole section 2a to be added is placed on top of an already mounted pole section 2b and then connected to it by a form-fit, force-fit, and / or material-fit connection. The assembly platform 1 according to the invention is provided for the erection of such a power pole 3.

[0101] However, the assembly platform 1 can also be used to dismantle an already erected power mast 3.

[0102] Ultimately, the assembly platform 1 serves in particular to attach a mast section 2a to be installed to an already mounted mast section 2b, as shown in the Fig. 4A bis 4C show in detail.

[0103] Fig. 4A Figure 1 shows that the assembly platform 1 is positioned on an already assembled mast section 2b. A mast section 2a is then placed on top of this already assembled mast section 2b and subsequently connected to the already assembled mast section 2b. This is shown in more detail in the figure. Fig. 4B shown. After the two mast sections 2a and 2b have been connected, it is possible to relocate the assembly platform 1 and, for example, connect it to the attached mast section 2a, which can then form the already mounted mast section 2b for a further mast section 2a to be attached. This is shown schematically in the Fig. 4C shown, which at least the arrangement of the assembly platform 1 on the previously assembled mast section 2a of the Fig. 4B , which now becomes the already assembled mast section 2b, shows.

[0104] The horizontal sections of a power pole 3 can also be erected using an assembly platform 1, although this is not shown in detail. In particular, the assembly platform 1 can then be positioned at the pole section 2b where the vertical sections are to be mounted.

[0105] In any case, the assembly platform 1 can serve as a work platform for fitters who are erecting the power mast 3.

[0106] In Fig. 1A It is further shown that the assembly platform 1 has at least four platform segments 4. In addition, the assembly platform 1 includes an adjusting device 5, which is provided for adjusting the platform segments 4 relative to each other or to change the opening cross-section 6 enclosed by the platform segments 4. The adjusting device 5 is shown in the Fig. 1A not shown in detail. However, such an actuating device 5 is shown schematically, for example, in the Fig. 5 highlighting that such an actuating device 5 is also used in a Fig. 1A The system shown can be used.

[0107] The assembly platform 1 further comprises a fastening device 7 for detachably attaching the assembly platform 1 to the already assembled mast section 2b. The fastening device 7 is not described in detail in the Fig. 1A depicted. The Fig. 22 In contrast, figure 7 schematically shows a possible fastening device, which may consist of or include a plurality of fastening elements 11. In the Fig. 11 bis 21 Another embodiment of a fastening means 11 is shown, which is used in a particularly preferred embodiment of the fastening device 7.

[0108] The fastening device 7 or the fastening means 11 can each comprise at least one rope, in particular wire rope, a hook, a chain and / or a clamp, a screw connector, a turnbuckle and / or a chain connector and / or other fastening systems and / or a combination or several of the aforementioned connecting means.

[0109] The Fig. 22 shows that the fastening device 11 has a rope secured with a locking system, wherein the fastening device 11 serves to connect to the corner posts 37 of the power pole 3, which are located in the Fig. 22 are not shown in detail.

[0110] Ultimately, the fastening device 7 can enable a secure, in particular force-fit and / or form-fit, connection to the already mounted mast section 2b.

[0111] As previously explained, the fastening device 7 may comprise a plurality of fastening elements 11. In particular, at least one fastening element 11 may be provided for each stage segment 4. The fastening element 11 may be arranged, at least partially, on the stage segment 4 to which it is assigned and / or cooperate with it to fasten the assembly platform 1.

[0112] It may be provided that one or more fastening means 11 are arranged on a stage segment 4.

[0113] In the Fig. 22 In the illustrated embodiment, all stage segments 4 can each have at least one fastening means 11.

[0114] The fastening elements 11 are designed or selected depending on the power pole 3 and are provided on the assembly platform 1. In particular, the fastening elements 11 are arranged interchangeably on the assembly platform 1, so that different fastening elements 11 of the fastening device 7 can be provided for different power poles 3. In particular, the fastening element 11 can only be arranged on the assembly platform 1 once the platform already surrounds the first assembled pole section 2b. When the assembly platform 1 is subsequently moved to erect the vertical section of the power pole 3, the fastening element 11 can then be released for movement, but remain connected to the respective platform segment 4, specifically in a "loosened, not tightened" state.

[0115] In practice, various forms of power poles 3 are known. The mounting platform 1 according to the invention can be used, in particular, for a large number of power poles 3. However, different power poles 3 may require that the respective fastening device 7 be designed differently. In the Fig. 1A and in the Fig. 5 Therefore, each assembly platform 1 is shown without a fastening device 7, since this fastening device 7 is provided or arranged on the platform segments 4 depending on different power poles 3 of the assembly platform 1.

[0116] The fastening device 7 is therefore individually interchangeable for different power pole shapes and therefore the mounting platform 1 can be used multiple times for different purposes thanks to the various fastening devices 7.

[0117] In the Fig. 11 The figure shows that the fastening device 7 comprises fastening elements 11, which are designed for attachment to the corner posts 37 of the power pole 3, which are designed as angle profiles. The fastening elements 11 can be brought into contact with the corner posts 37 of the power pole 3 by means of a lever or joint mechanism and then frictionally connected, thus enabling a clamping connection between the power pole 3 and the platform segment 4. The fastening elements 11 have frictional locking elements 38, 39, which function functionally as brake shoes. These frictional locking elements 38, 39 interact with the corner post 37 in the respective area where they are located by being pressed against each other by the joint mechanism 40. The corner post 37 can be positioned between the frictional locking elements 38, 39 when fastened, so that the fastening device 11 can be considered functionally as a disc brake.

[0118] In the Fig. 1A The figure shows that the stage segments 4 form a closed stage frame 8 for enclosing the already assembled mast section 2b. Support elements 30 can be provided for bracing or attaching to the already assembled mast section 2b, which are located in the Fig. 1A , but also in detail in the Fig. 6A as well as in the Fig. 6B are shown.

[0119] The Fig. 6B shows in detail detail B from the Fig. 6A . The Fig. 1B Detail A again shows from the Fig. 1A , in the Fig. 1B However, the support means 30 are not clearly visible. In particular, a roller can be provided as a support means 30, so that the assembly platform 1 can be supported against the already assembled mast section 2b and moved along the already assembled mast section 2b as required.

[0120] However, moving the assembly platform 1 along the already assembled mast section 2b requires detaching the fastening device 7 from the already assembled mast section 2b. For this, it will be necessary, in particular, to lift the assembly platform 1 using external lifting equipment, for example, a crane equipped with a cable pulley system for raising or lowering the assembly platform 1, so that the assembly platform 1 can be moved relative to the already assembled mast section 2b. This is required, for example, if the assembly platform 1 is to be relocated or moved, as shown schematically in a comparison of the Fig. 4B und Fig. 4C This is further illustrated. It can be provided that this external lifting tool (for example, a crane with a cable pulley system) is firmly connected to the assembly platform 1, in particular by positive and / or non-positive locking, and after the firm connection to the external lifting tool, the fastening device 7 can be detached from the already mounted mast section 2b. The assembly platform 1 can then be moved along the power pole 3, whereby the support elements 30 can then be braced against the mast sections 2b.

[0121] In Fig. 5B An alternative embodiment of an assembly platform 1 according to the invention is shown. In this embodiment, a lifting device 32 is provided on each platform segment 4, preferably in an area adjacent to the first end face 13. Furthermore, each of the lifting devices 32 is located adjacent to the inner longitudinal side 14 of the respective platform segment 4. Each of the lifting devices 32 has a fastening device 33 at its end, which is provided for attachment to an already mounted mast section 2b. The fastening device 33 can, for example, be a hook. The fastening device 33 is connected to a traction device 34, which in turn is coupled to a motor device 35. The traction device 34 can be at least one rope, a chain, or a rack and pinion, while the motor device 35 can be a winch or a rack and pinion drive.Preferably, all lifting devices 32 are controlled via a common lifting control unit 36, which either actuates all lifting devices simultaneously or, when one lifting device 32 is actuated, activates the other lifting devices simultaneously. This ensures that all lifting devices move in the same direction simultaneously upon activation. In this embodiment, the assembly platform 1 is moved without an external lifting tool.

[0122] In principle, it is also possible to design the fastening elements 11 completely or at least partially as lifting devices 32. In this case, however, simultaneous activation of all lifting devices is not possible. To change the mounting position of the assembly platform 1, the individual fastening elements 11 must each be loosened separately and attached one after the other in the upper area of ​​the last mast section 2b that was already mounted. If a fastening element 11 is loosened, it is understood that the remaining fastening elements 11 must be designed to bear the load of the assembly platform 1 with sufficient safety. Once all fastening elements 11 have been repositioned accordingly, the fastening elements 11, designed as lifting devices 32, can move the assembly platform 1 to the new mounting position.

[0123] Once the assembly platform 1 has reached the required working height, it can be reattached to the mast section 2b, in particular by connecting the fastening device 7 to the mast section 2b. The fastening device 7 can be designed accordingly for this purpose. Specifically, the fitters positioned on the assembly platform 1 can then attach the platform 1 to the fastening device 7 and the mast section 2b. As previously explained, various fastening elements 11 of the fastening device 7 would be suitable for this purpose, in particular detachable hooks, clamps, rope and / or chain systems, and / or other detachable locking elements attached to the platform segment 4. Once the assembly platform 1 is firmly connected to the mast section 2b again, the attachment to the external lifting device can be released if necessary.

[0124] In this way, a high level of occupational safety protection for the fitters is always guaranteed.

[0125] For attachment to the mast section 2b, the corner posts 37 and, in further embodiments, the cross braces 9 and / or the horizontal braces 10 of the mast section 2b can be used as needed. In particular, the power pole 3 comprises at least four corner posts 37, which are arranged in the corners of the mast sections 2a, 2b of the vertical section of the power pole 3.

[0126] In the Fig. 4D An embodiment of a vertical section of a power pole 3 is shown, which, in addition to the corner posts 37 and the cross braces 9 connecting the corner posts 37, also includes horizontal braces 10. The horizontal braces 10 are, in particular, oriented at least substantially horizontally with respect to the ground. Furthermore, the horizontal braces 10 can also connect two opposing corner posts 37.

[0127] In further embodiments, the fastening device 7 can then be suspended from and / or firmly attached to at least one strut 9, 10. However, a friction-fit connection of the fastening means 11 with the corner posts 37 is preferred, which will be discussed in more detail below.

[0128] In particular, the fastening means 11 can be detachably connected by force-locking and / or form-locking to at least one strut 9, 10 and / or to a corner post 37 of the mast section 2b.

[0129] To change the opening cross-section 6, each stage segment 4 is slidably mounted with its first end face 13 on a longitudinal side 14, in particular on an inner longitudinal side 21, of an adjacent stage segment 4, as can be seen from the Fig. 1B detailed view of detail A shown from the Fig. 1A emerges.

[0130] The Fig. 1B shows that the first end face 13 of a stage segment 4 is arranged on the long side 14 of an adjacent stage segment 4. The comparison of the Fig. 1A and the Fig. 2 This illustrates that the stage segments 4 can be shifted relative to each other, which necessitates a change in the enclosed opening cross-section 6. Thus, the Fig. 2 another condition of the in Fig. 1A assembly platform 1 shown.

[0131] Even the Fig. 3A und 3B The top view shows two different states of an assembly platform 1, which can be achieved by the relative displacement of the platform segments 4 relative to each other, whereby the opening cross-sections 6 also change in this context. Thus, the Fig. 3A the minimum opening cross-section 6, which is required for the Fig. 3A The illustrated assembly platform 1 can be made possible, whereas the Fig. 3B shows the maximum opening cross-section 6.

[0132] From the Fig. 2 It becomes apparent that the stage segments 4 can be shifted relative to each other such that each stage segment 4 is positioned with its first end face 13 against an inner longitudinal side 21 of the adjacent stage segment 4. The other end face 19 of the stage segment 4 can be positioned against and / or adjoin an adjacent stage segment 4, at least when the maximum opening cross-section 6 is occupied, as shown by the Fig. 2 shows.

[0133] However, the other end face 19 cannot, in particular, directly adjoin an adjacent stage segment 4, as the Fig. 1A shows. Then the further end face 19 forms in particular the free end of the stage segment 4. A displacement of the stage segments 4 relative to each other thus leads to a change in the opening cross-section 6.

[0134] It is understood that, because all stage segments 4 are arranged next to each other and connected to one another, and are operatively linked, the displacement of one stage segment 4 causes a displacement of the other stage segments 4. This is also demonstrated by comparing the Fig. 3A und 3B clearly.

[0135] The positioning device 5 can comprise longitudinal guide rails 15 arranged on the stage segments 4, which are described in detail, for example, in Fig. 1B as illustrated. Each stage segment 4 can have at least one guide rail 15 – and in further embodiments, a plurality of guide rails 15. The stage segment 4 can be movably mounted with its first end face 13, in particular along the guide rail(s) 15. The guide rails 15 can extend along the inner longitudinal sides 21 of the stage segments 4.

[0136] In the Fig. 1B The first end face 13 is shown to abut the guide rail 15 of the adjacent stage segment 4, in particular to be arranged in and / or on it. For this purpose, the first end face 13 can in particular comprise a support frame 28 which engages in at least one guide rail 15 of the adjacent stage segment 4 and can also be moved along this guide rail 15. The support frame 28 will be discussed in more detail below.

[0137] The guide rail 15 thus makes it possible to specify the direction of movement of the adjacent stage segment 4, which is to be moved, when moving the stage segments 4 against each other.

[0138] In Fig. 5 The figure shows that the adjusting device 5 has a cable pull system 16 for adjusting the stage segments 4 relative to each other. The cable pull system 16 can be operated, in particular, when the assembly platform 1 is mounted on the power pole 3, preferably by fitters or operators arranged on the assembly platform 1.

[0139] In particular, the previously discussed height adjustment of the assembly platform 1 requires actuation of the cable pull system 16 or the adjusting device 5 so that the assembly platform 1, with its opening cross-section 6, can adapt to different external shapes of the power pole 3 or the pole section 2b. Specifically, the vertical section of a power pole 3 tapers upwards, so that a reducing opening cross-section 6 of the assembly platform 1 can adapt to this tapered shape.

[0140] The cable system 16 can be operated manually or by motor, in particular via an electric winch 26. Furthermore, the cable system 16 can also comprise several cables 17, 22. The cable system 16 can also be used, as previously described, to raise or lower the assembly platform 1.

[0141] Furthermore, the cable pull system 16 is arranged in particular on the assembly platform 1 itself and is arranged in particular on the power mast 3 on the assembly platform 1 both when raising and when lowering the assembly platform 1 and is also required in the illustrated embodiment to change the opening cross-section 6.

[0142] The Fig. 6A shows the in Fig. 5 The illustrated assembly platform 1 in a second state, namely with a maximum enclosed opening cross-section of 6. Fig. 6A further shows that the cable system 16 has at least one outer cable 17 running along the outer longitudinal sides 20 of the stage segments 4. In Fig. 6B An additional inner rope 22 is shown, which runs along the inner longitudinal sides 21 of the stage segments 4. Both the inner and the outer rope 17, 22 can be part of the rope pulley system 16.

[0143] It is not shown in detail whether the cable system 16 comprises only an outer cable 17 or only an inner cable 22.

[0144] Furthermore, they affect the Fig. 6B The inner and outer ropes 17, 22 shown are connected together, so that a change in the length of one rope 17 or 22 results in a change in the length of the other rope 22 or 17.

[0145] Thus, pulling in the outer rope 17 can increase the enclosed opening cross-section 6 between the stage segments 4, whereas pulling in the inner rope 22 can cause a reduction in the enclosed opening cross-section 6.

[0146] In addition to the outer longitudinal sides 20, the outer rope 17 can also encircle further end faces 19 opposite the respective first end face 13, which is particularly evident from the Fig. 7 and 8 emerges.

[0147] The Fig. 7 bis 10 The figures show an assembly platform 1 with a cable pulley system 16, which comprises an inner and outer cable 17, 22. In the Fig. 7 and 8 The dashed line also illustrates a possible relocation or displacement of the stage segments 4, which leads to a change in the enclosed opening cross-section 6. Thus, the Fig. 7 For example, that if the two stage segments 4, which are opposite each other, are moved, a different state can be achieved, which is in the Fig. 7 is shown schematically with dashed lines. Also the Fig. 8 Figure 1 shows a possible change in the opening cross-section 6 by means of a dashed representation of the stage segments 4 in a second state. Arrows indicate the direction of movement of the stage segments 4 to be moved.

[0148] Furthermore, the detailed views in particular show Fig. 9 and 10 , which include details C and D of the Fig. 7 and 8 show that the cable system 16 comprises the outer and inner cables 17, 22. Thus, it follows from the Fig. 9 For example, it clearly shows that the inner rope 22 is guided around the first end faces 13, or that a corresponding angle of the inner rope 22 is provided at the first end faces 13. Furthermore, the Fig. 9 , that the inner rope 17 is guided along the inner longitudinal sides 21 of the stage segments 4.

[0149] In contrast, the Fig. 10 , that the outer rope 17 can be guided around the further end faces 19 and extends furthermore along the outer longitudinal sides 20 of the stage segments 4.

[0150] Not shown is that in further preferred embodiments the inner rope 22 may be guided on and / or in the guide rails 15 of the stage segments 4.

[0151] Pulleys 18 and 23 can be used to guide the ropes 17 and 22 of the rope pulley system 16. For example, outer pulleys 18 can be used for the outer rope 17 and inner pulleys 23 for the inner rope 22. These inner and outer pulleys 18 and 23 extend, for example, from the Fig. 9 and 10 highlights. This shows that Fig. 9 , that inner deflection pulleys 23 are provided for deflecting the inner rope 22, wherein at least one inner deflection pulley 23 is arranged at or adjacent to the first end face 13 of a stage segment 4.

[0152] In Fig. 10 However, it is shown that the outer deflection pulleys 18 are provided for deflecting the outer rope 17, wherein at least one outer deflection pulley 18 is provided at the first end face 13 of a stage segment 4 and at least one further outer deflection pulley 18 is provided at the further end face 19, in particular two outer deflection pulleys 18. The transfer of the outer rope 17 from the outer longitudinal side 20 of a stage segment 4 to the further end face 19 of the adjacent stage segment 4 can also be ensured via the outer deflection pulleys 18, as shown in detail in Fig. 10 is shown.

[0153] The pulleys 18, 23 thus enable the ropes 17, 22 to be guided safely.

[0154] In Fig. 1A The schematic diagram shows that the platform segment 4 comprises an elongated lower floor section 24 and side sections 25, in particular fall protection grating side sections, projecting upwards from the floor section 24 on both longitudinal sides. The fall protection grating side sections 25 can also be referred to as longitudinal fall protection units if required. The fall protection grating side sections 25 and the floor section 24 enable fitters positioned on the assembly platform 1 to move around safely on the assembly platform 1.

[0155] As previously explained, at least one winch 26 can be provided to operate the cable pull system 16. The winch 26 can be motor-driven or designed as a hand winch. At least one cable 17, 23 can be operated via the winch 26 as needed. In particular, at least one winch 26 is provided for operating, i.e., for pulling in or releasing, each cable 17, 22.

[0156] In Fig. 6B The figure shows that the winch 26 is arranged on at least one stage segment 4. In particular, at least one winch 26 is provided for each inner rope 22 and each outer rope 17, as shown in the figure. Fig. 10 shows.

[0157] In the Fig. 1A Figure 1 shows that a fall protection unit 27, in particular a fall protection grid, is arranged on the further end face 19, projecting upwards from the floor section 24. This fall protection grid is also shown schematically in the Fig. 6B The fall protection grid extends upwards from the floor section 24 and ensures that there is no danger to operators of falling over the further front face 19 into the depths below.

[0158] In addition to the fall protection unit 27, a passage barrier 29 may be provided, which may impede access to the area between the passage barrier 29 and the further end face 19, which is shown schematically, for example, in the Fig. 1B The passage barrier 29 can be arranged on the first end face 13 and / or on the support frame 28 of an adjacent stage segment 4 and block the passage between another end face 19 and the passage barrier 29. The passage barrier 29 can then connect or span the two side sections 25 of the stage segment 4, as shown schematically in the Fig. 1B and 6B emerges.

[0159] As explained above, the fastening element 11 may optionally be arranged on or interact with the support frame 28. The support frame 28 is shown schematically in the Fig. 1B As shown. In addition to the possible arrangement for the fastening device 11, the support frame can also be designed for coupling with a lever-operated cable system, which is, for example, attached to a crane and / or intended for raising or lowering the assembly platform 1. The support frame 28 can be arranged on the first end face 13. In particular, the support frame 28 projects upwards from the immediately adjacent side section 25, as shown. Fig. 1B as also shown. The support frame 28 can further be provided for adjusting the stage segments 4 against each other or relative to each other, in particular by coupling the support frame 28 to the guide rails 15 and being slidable along these guide rails 15. For this purpose, the support frame 28 can optionally have suitable guide means, such as rollers or the like, which can then interact with the guide rail 15.

[0160] As previously explained, the support frame 28 can, as required, alternatively or additionally be provided for coupling with a lever-operated cable system for raising or lowering the assembly platform 1. In the Fig. 1B The figure shows that the support frame 28 has corresponding openings 31 on its upper side, which can be used to guide ropes, in particular wire ropes or fiber ropes. Thus, the support frame 28 can allow both a displacement of the stage segments 4 relative to each other and a vertical displacement of the assembly platform 1.

[0161] The following describes an embodiment of a fastening device 7 with four fastening means 11, each of which is frictionally connected to a corner post 37 of the vertical section of the power pole 3 or is "clamped" to the corner posts 37 in the fastened state. This embodiment is described in the Fig. 11 bis 21 shown.

[0162] The Fig. 11 bis 13 Figure 1 shows the unfastened state of the fasteners 11, in which a gap is provided between the fasteners 11 and the corner post 37. This state of the fasteners 11 is required for moving the assembly platform 1, particularly when its working height is to be changed, as shown schematically in the figures above. Fig. 4A bis 4C This is illustrated. Furthermore, this unsecured state of the fastener 11 can be fixed, if necessary, by means of a fixing device (not shown in detail), so that the fastener 11 cannot collide with the corner post 37 when the height of the assembly platform 1 is adjusted. In particular, this fixing device (not shown in detail) can also have a lever mechanism that can move the fastener 11 into the secured state.

[0163] The Fig. 14 bis 20 show this in the Fig. 11 bis 13 Fastening means 11 shown in the fastened state, in which the fastening means is at least partially in direct contact with and / or adjacent to the corner pillar 37 and interacts with it in particular by friction.

[0164] The Fig. 21 The fastening element 11 again shows how it is used in the Fig. 11 bis 20 shown in the state connected to stage segment 4, taken on its own.

[0165] The in the Fig. 11 bis 21 The fastening element 11 shown has at least one first frictional locking element 38 – namely, in the illustrated embodiment, two first frictional locking elements 38 – and at least one second frictional locking element 39, which, in the fastened state of the mounting platform 1, frictionally interacts with each of the first frictional locking elements 38. Fig. 17 It is clearly evident that two frictional locking elements 39 are provided.

[0166] A first frictional locking element 38 is functionally assigned to a second frictional locking element 39, both of which interact like brake shoes in the fixed state, as can be seen from a comparison of the Fig. 13 (unsecured state) and the Fig. 16 (fixed state) becomes clear.

[0167] The two second frictional locking elements 39 can be connected to each other, in particular via an angle profile 51. In the fastened state, the angle profile 51 can be arranged directly on the outer side of the corner pillar 37 facing the stage segment 4 and, in particular, can be designed corresponding to the angle shape of the corner pillar 37, thus enabling a direct abutment against the corner pillar 37. In particular, the corner pillar 37 has an angle α between its two legs in the area where the angle profile 51 is arranged, and the legs of the angle profile 51 also enclose this angle α ± 5° to each other, at least substantially, as shown by the Fig. 19 shows.

[0168] The second frictional locking elements 39 can preferably be connected to the angle profile 51 by material bonding, force bonding and / or form bonding or be formed integrally with it.

[0169] The first two frictional elements 38 cannot, in particular, be directly connected to each other, as can also be seen from the Fig. 18 This is evident. A stop plate 54 can be provided between a first friction-locking element 38 and the corner post 37, which, particularly in the fastened state, bears directly against a leg of the corner post 37. The first friction-locking element 38 can be formed integrally with the stop plate 54 or connected to it by a material bond, a positive fit, and / or a force-fit. The stop plate 54 ensures optimized force transmission into the corner post 37, even with uneven surfaces, and improves the bearing surface of the first friction-locking element 38. This also applies to the function of the angle profile 51 for the second friction-locking elements 39.

[0170] Fig. 20 Figure 1 shows that the corner post 37 of the already assembled mast section 2b is arranged between the first and second friction locking elements 38, 39. It is understood that only that part of the corner post 37 which directly adjoins the friction locking elements 38, 39 is arranged between them. In the unfastened state, the corner post 37 can also be arranged between the friction locking elements 38, 39; however, the friction locking elements 38, 39 do not lie directly against the corner post 37, as shown in Figure 2. Fig. 13 also shows.

[0171] The Fig. 16 shows that in the fastened state the frictional locking elements 38, 39 act on opposite sides of the corner pillar 37 and thus the frictional forces necessary to hold the assembly platform 1 can be applied.

[0172] To secure the assembly platform 1, the fastener 11 is inserted into the Fig. 11 bis 13 The assembly platform 1 or the platform segments 4 are then slowly lowered. This allows the fastener 11 to "engage" and secure the mounting. This requires a relative movement between the two frictional locking elements 38, 39, as a comparison of the Fig. 11 and 14 The second friction elements 39 lower together with the stage segment 4 in the illustrated embodiment, whereby the first friction elements 38 are held, in particular, at least substantially in their previous position. A fixing device, which is not shown in detail, can also be used to hold the first friction elements 38, if required. A joint mechanism 40 connecting the respective friction elements 38, 39 is actuated when the stage segment 4 is lowered, as a comparison of the Fig. 14 and 15clarifies, with the joint mechanism 40 described in more detail in the Fig. 21 The illustrated embodiment consists of two levers 40, 41. The joint mechanism 40 lowers the second friction elements 39, thereby creating a frictional connection between the two friction elements 38, 39. In the illustrated embodiment, a frictional connection occurs on both legs of the corner pillar 37 through the interaction of two pairs of first and second friction elements 38, 39.

[0173] The joint mechanism 40, as it is described in the Fig. 20 and 21 As shown, it is therefore intended for the interaction of the first and the second frictional locking element 38, 39.

[0174] In Fig. 18 The figure shows that the joint mechanism 40 is fixedly, in particular rigidly, connected to the first and second frictional elements 38, 39 at individual bearing points. Thus, at a first bearing point 46, the joint mechanism is fixedly, in particular rigidly, materially, and / or positively connected to the first frictional element 38, in particular to a stop area 43 of the first frictional element 38. Simultaneously, at a second bearing point 47, the joint mechanism 40 is fixedly, in particular rigidly, materially, and / or positively connected to the second frictional element 39.

[0175] The Fig. 17 , but also the Fig. 18 Figure 1 shows that the joint mechanism 40 is rigidly connected to the stage segment 4 at one point, namely at a third bearing point 48. In the illustrated embodiment, the joint mechanism 40 is rigidly and / or materially connected at the third bearing point 48 to a stage segment support element 50, in particular a stage segment support element 50 belonging to the support frame 28. A pin 52 can be provided for the connection, as shown in Figure 2. Fig. 17 shows.

[0176] The joint mechanism 40 comprises at least one joint that ensures the movement and actuation of the joint mechanism 40.

[0177] Fig. 21 Figure 1 shows that the joint mechanism 40 is designed such that the frictional locking elements 38, 39 are adjustable relative to each other and / or can be aligned with each other. The relative adjustment is required, in particular, as explained above, for securing the mounting platform 1 and for tightening the fastening element 11.

[0178] Fig. 17 and 18 Show that the joint mechanism 40 has a first lever 41 that can be connected, in particular rigidly, to the first and second frictional locking elements 38, 39, and a second lever 42 that can be connected, in particular rigidly, to the stage segment 4, in particular to the support frame 28. The levers 41, 42 are connected to each other via a pivot point 49.

[0179] The first and second bearing points 46, 47 are provided on the first lever 41 and the third bearing point 48 on the second lever 42, with both levers 41, 42 being connected to each other via a joint at the pivot point 49, as previously explained. Fig. 18 The first bearing point 46 and the pivot point 49 are provided at opposite ends of the first lever 41, with the second bearing point 47 being located, in particular, at least substantially in the middle of the first lever 41. The third bearing point 48 and the pivot point 49 are also located at opposite ends of the second lever 42.

[0180] The Fig. 18 and 19The first frictional locking element 38 has a stop area 43 and a connecting section 44. The stop area 43 serves to be positioned against the corner post 37, in particular for direct contact with the stop plate 54. The stop area 43 abuts the inner side of the corner post 37 facing away from the stage segment 4, or rests against this inner side. Functionally, the stop area 43 acts as a brake shoe. The connecting section 44, in turn, ensures the arrangement and connection to the stage segment 4. For this purpose, the connecting section 44 is designed to project from the stop area 43, in particular at least substantially at a right angle. The connecting section 44 thus bridges the gap to the stage segment 4 and serves to connect the joint mechanism 40 to the support frame 28 or the stage segment support element 50.

[0181] The first lever 41 is fixedly connected to the stop area 43 at the first bearing point 46, in particular by a material connection and / or rigidly, preferably via a pin 52, as shown. Fig. 21 shows.

[0182] The Fig. 11 and 14 Show that the connecting section 44 of the first friction-locking element 38 has a guide area, in particular an elongated hole, for guiding a pin 52 of the second lever 42, which engages in the guide area and is firmly, in particular by a material bond and / or rigidly, connected to the stage segment 4, preferably to the support frame 28 and / or a stage segment support element 50. The pin 52 engaging in the guide area is in particular movable and displaceable relative to the guide area, thereby ensuring the adjustment and displacement of the friction-locking elements 38, 39 relative to each other for fastening the stage segments 4.

[0183] Consequently, for the purpose of securing the assembly platform 1, the second frictional locking element 39 is mounted in a manner that allows movement relative to the first frictional locking element 38 or to the stop area 43 of the first frictional locking element 38.

[0184] To fasten the second friction-locking element 39 to the angle profile 51, at least one reinforcement 53 can be provided, as shown in the Fig. 19 The reinforcement 53 can be provided, in particular, for stabilizing and fixing the second frictional locking elements 39. Specifically, the second frictional locking elements 39 are arranged on the outer longitudinal sides of the legs of the angle profile 51. The longitudinal side facing the outer longitudinal edge of the leg of the angle profile 51 is not reinforced, but the opposite longitudinal side can be supported, in particular, by two reinforcements 53. The reinforcements 53 are shown in the Fig. 19The illustrated embodiment is designed as at least substantially triangular plates and enables improved force transmission first into the angle profile 51 and then into the corner pillar 37.

[0185] A projection 45 can be arranged on the connecting section 44, which serves to attach to the stage segment support element 50, as shown in the Fig. 20 The projection 45 is not rigidly connected to the stage segment support element 50 or the support frame 28, but ensures, when the joint mechanism 40 is moved, that the first frictional locking element 38 and the joint mechanism 40 remain correctly aligned with the support frame 28 and thus enables, in particular, the centering of the joint mechanism 40 and / or the first frictional locking element 38 or the connecting section 44.
