Description

The invention relates to a device for tunneling, in particular for laying a seal in the tunnel, wherein the device is moved a roll of a sealing film or geomembrane along the inner wall of the tunnel to mount the film or web to the tunnel inner wall, and / or or with the Device a working platform is moved as a stand for the fitters in the tunnel.

For tunnels that run through water-bearing mountain strata, a watertight tunnel construction is provided.

Usually the tunnel construction consists of concrete. In non-stable mountains is spoken of concrete Ausaubau, which withstands the mountain pressure. The stable mountains are self-supporting. There, a supporting expansion is unnecessary. Nevertheless, concrete in the form of shotcrete is also used in the stable mountains in order to consolidate the mountain outbreak or to effect thermal insulation and waterproofing. Consolidation means securing the mountain outbreak against falling loose stones. It is understood that the falling stones bring a high risk of accidents with it.

The thermal insulation and water seal should prevent the formation of ice and falling ice in winter.

For this purpose, an expansion of shotcrete, and a seal made of plastic films or plastic sheets is known in the stable mountains.

In stable mountains usually anchor holes are first drilled in the mountains. Anchors are placed in the anchor holes where they are clamped or held in place with mortar or adhesive. The anchors serve the Fixing the foil or web. For attachment to the anchors fasteners are provided, which may have various shapes. In part, the fasteners are known as roundels.

Instead of anchors, another mounting of the fastener may be provided. For example, roundels can also be shot at the mountains or a shotcrete layer provided on the mountain side.

The webs have manufacturing reasons, transport reasons and other handling reasons only a certain width and are usually laid in the circumferential direction of the tunnel in such a way that a film section or web section in the tunnel longitudinal direction is adjacent to the other and overlapping the adjacent section at the edge. After laying, the films or webs are welded together in the overlapping area. Usual are two adjacent welds.

For welding welding machines can be used, which - electrically driven - move with rollers on the overlap edge and cause the necessary heating of the welding surfaces. The known devices regularly have welding wedges on which the welding surfaces of the overlap edges slide along to be fused and then pressed against each other by pinch rollers. As a result, the customary for welding welding pressure is generated.

The juxtaposed welds are called test seams, because the gap with a test medium, for example air, can be acted upon. If within a certain time a certain pressure drop is not exceeded.

Optionally, other webs are laid before or after laying the film or web. These are textile webs. The textile webs have a protective function and / or a drain function. They protect the film or web against falling stones and direct the escaping mountain water down the tunnel wall.

Optionally, a shotcrete layer is applied to the rock eruption before drilling the anchor holes or after setting the anchor under protection of the assembly ends. This can serve to protect against leaching stones from the mountain outbreak.

In the stable mountains, a shotcrete layer is built on the tunnel inside the seal. As with shotcrete there is a risk that the shotcrete rebounds from the film or web. To prevent this, a wire mesh or the like may be mounted in front of the film or web before applying the shotcrete. The mesh size is chosen so that the shotcrete penetrates, but does not fall out again.

Optionally, the wire mesh or the like also has a reinforcing function.

The shotcrete forms a solid concrete shell, which has more or less distance from the mountain eruption, optionally, the distance is an inspection distance. That is, the distance is so large that the interior is accessible.

The shotcrete causes some expense, but is still considered an economical solution.

In non-stable mountains, a reinforcement for an inside concrete layer is mounted in front of the foil or sheet. The reinforcement consists of customary or special welded steel mesh or reinforcing steel.

Subsequently, a formwork carriage can be positioned in the tunnel and the space between the film or web and the shuttering car be filled with concrete. With the formwork car usually tunnel / concrete sections are poured. Between the individual tunnels / concrete sections seals, so-called joint tapes are provided.

The tunnel work requires a lot of overhead work or other strenuous work.

The films are peeled from a roll and positioned by hand and attached to the anchors. The larger the tunnel cross-section, the longer the films are. The longer the films become and the larger the film width becomes, the more strenuous the assembly becomes. This is especially true in the ridge area of the tunnel, where the fitters have to work overhead.

It is therefore much easier to work when the film roll is carried in the work platform. As a result, the length of the film to be moved by hand is shortened to a fraction of the previous length. Correspondingly, the physical strain on fitters is reduced.

Carrying the film roll is preferably called that either on the platform for the fitters a roll holder is provided and / or that the role is carried with a separately movable roll holder.

Optionally, this device can also be used if other materials are laid before or after the laying of the film. These are textile webs. The textile webs have either a protective function or a drain function.

Similarly, the device can also be used if an insulation made of plastic foam is attached to the anchors or elsewhere in the expansion.

Furthermore, the device can also be used to be attached to the anchors or elsewhere in the removal of fire protection boards.

With the DE 3841455 A1 is therefore already proposed a device to support the tunnel work but not yet come to fruition.

moreover, is from the EP1493899A a device for tunneling, in particular for laying a seal in the tunnel known. This known device has:

• e) a roll of a sealing film or sheet, the roll being moved with a pivoting device along the tunnel inner wall to mount the film or sheet to the tunnel interior wall,
• f) wherein the pivoting device has length-adjustable pivot arms and carries a working platform as a base for persons,
• g) the device stands on stilts and forms a portal.

The from the EP1493899A known device serves as a laying aid. This device has access advantages over some other known devices.

According to the invention, therefore, the changes contained in claim 1 are provided.

The stilts turn the movable device into a portal car. The advantage of the portal car is the high ground clearance. In the tunnel are regularly other devices and various materials that can drive over the portal car. That is, the tunnel does not have to be cleared completely free to drive with the device according to the invention the tunnel. Only very small lanes need to be opened.

In addition, the portal trolley can be crossed with other vehicles and laying crews. That is, the device according to the invention does not have to be driven out of the tunnel first to drive the tunnel with other vehicles.

Preferably, a Unterfahrungsmöglichkeit with trucks is provided. For this purpose, it is advantageous if the device exceeds the respective passage height not more than 1m, preferably not more than 0.8m.

In addition, depending on the design, a larger clearance height obtained when the pivot arms of the pivoting device are retracted and the pivoting device in a favorable position and when the device is driven into the center of the tunnel.

For the method of the device wheels are particularly favorable, the rotatable in all directions / schwenkbeglich and / or with individual drives are provided. Experienced operators offer the virtuoso driving possibilities. For less experienced operators, on the other hand, it may be advantageous if the wheels are fixed in a conventional manner. Nevertheless, the device can still be limited in that the wheels are braked or accelerated on one side of the device relative to the wheels on the other side. Nevertheless, the steering of the device is still particularly easy if a mark is provided for the device on the tunnel sole. As a marker are, for example, strokes or edges or points on the tunnel sole.

Instead of the wheels, tracked vehicles (chains) and chassis with belts can also be used.

The chains and belts have like the schwenkunbewcglich arranged wheels a limited steerability.

The chains and bands are far less dependent than wheels on an attachment of the route. For wheels is particularly useful with a smaller diameter and a tunnel sole, which has at least already the support layer for the roadway. Even better conditions arise when a wear layer for the roadway is already provided on the base layer. Although the dependence of the wheels on the ground reduces with increasing diameter. However, at the same time increases the design effort for the steering and the drive.

With chains and bands, the device according to the invention can easily drive on an unpaved tunnel sole. This is particularly important for railway tunnels, which, unlike road tunnels with no comparable surface, remain at the tunnel floor.

Preferably, the stilts of the device according to the invention are also still pivotable or arranged telescopically to the side of the device. By swinging in and out of the stilts or the lateral Austeleskopieren the width of the device is changed. For the Pivoting and lateral telescoping are the above-mentioned pivoting wheels advantageous because they can be easily rotated in the pivoting direction or in the telescoping direction.

For wheels with limited freedom of movement and chains and belts pivoting may be possible that individual stilts are retracted and thus the grip is reduced so far, if necessary. Even a certain ground clearance is generated on the wheel in question, so that a pan or telescope without more is possible.

In devices with chains and belts as chassis a similar reduction in traction and ground clearance of individual stilts as in the wheels can be produced. As far as the chains and bands do not allow sufficient freedom of movement for a large pivoting movement and large telescoping movement, it is also possible to work in the alternating step. Change step means that the stilts alternate on one side and are moved stepwise by the permissible amount. Optionally, the device can be jacked for pivoting and for lateral telescoping of the stilts also on the relevant page. For this purpose, preferably supports that are extended out of the frame of the device down. Structurally favorable conditions arise when the device for this jacking is brought to minimum height. Then the length of the support can be made small.

It is favorable if the device has different hydraulic drives and for the movement of the support a hydraulic power piston is provided.

For Austeleskopieren same or similar pipe guides can be provided as for telescoping for height adjustment. The same applies to the telescopability of Schwenkbarme.

As far as it matters, can be increased by tilting or lateral Austeleskopieren the stilts, the stability of the device against tipping. Preferably, the device is at least as wide and so difficult to understand that in a two-lane traffic tunnel and the mountain eruption can be processed on the adjacent track when the device is on a track.

This is extremely important for repair work.

Even more preferably, the width of a device with inwardly pivoted stilts is smaller than a traffic lane and with fully swung out stilts greater than 1.3 times the same traffic lane. Most preferably, the width of the fully deployed stilts device is greater than 1.5 times the traffic lane. At the same time, the swivel arm of the working platform carrying the pivoting device is so far extended that it preferably extends at least over an entire traffic lane. Advantageously, the device according to the invention can consequently be arranged laterally in a two-lane traffic tunnel and leave a traffic lane free, without the working area being impaired. The released traffic lane can be released for traffic, as long as the lane is not being worked on.

With the stilts, the device according to the invention forms a gantry vehicle with appropriate ground clearance between the stilts. Preferably, the ground clearance is at least 2 m, more preferably at least 2.5 m, so that the device can be traversed by cars and other vehicles and people. Even better is when the ground clearance in the underride area is so large that a truck can drive under the device.

The gauge of the device can be changed before driving on the tunnel or while driving. This can be used to adapt to the opening width of the tunnel or to avoid obstacles.

The stilts can consist of telescoping tube profiles. The telescoping is synonymous with telescoping. at the telescoping is provided between the pipes a sufficient, but close movement play.

When using box profiles (tube profiles with rectangular cross section) is secured by the shape of the profile a rotationally secure position of the profiles. But there are also other profiles with corners that can glide safely into each other. Similarly, round profiles can be used with a rotation lock.

The displacement / telescoping of the stilts or the laterally extendable arms or the pivot arms of the pivoting device can be effected with different drives. In turn, hydraulic or pneumatic cylinders / power pistons which are arranged within the profiles are suitable. Electric drives and mechanical and combined drives are also possible.

The quarter-turn actuators can also be hydraulic, hydraulic, mechanical drives.

As far as a hydraulic drive is provided, a hydraulic circuit is also used. As soon as a hydraulic circuit is available, further hydraulic drives can be switched into the hydraulic circuit. The more hydraulic drives are provided, the more favorable the admission of the drives with hydraulic fluid. The hydraulic circuit includes valves and at least one pump. The valves are preferably controlled electronically and by means of a computer.

In the hydraulic circuit is preferably used as hydraulic fluid water or oil.

The proposed drives are preferably designed as stepping mechanisms, so that an accurate motion control is possible. As far as drive are actuated in dependence on each other, a synchronization control for equal movements and a lock for successive movements is provided.

Moreover, it is preferably prevented with an emergency lock in the event of malfunction that perform individual uncontrolled movements.

For drives, which are arranged within the stilts, is advantageous if the stilts have recesses through which the drives are accessible. The exceptions can show any shape. The exceptions can be incorporated with modern tools, for example by burning in each tube.

The shape and the distances of the recesses are limited by the statics of the tubes. Favorable are circular recesses with a diameter smaller than 30cm, preferably with a diameter smaller than 20cm. The distance of the circular recesses is at least equal to 1/3 of the diameter, preferably at least equal to half the diameter and most preferably at least equal to 2/3 of the diameter.

To the mechanical drives may include threaded spindles which are rotatably disposed in the one tube profile and are moved for example by a drive motor and press against the other tube profile or pull it. On the threaded spindles can run a so-called lock, which is connected to the other pipe profile.

As a lock, a workpiece is referred to with a bore which forms the inside of the corresponding thread to the external thread of the threaded spindle. If the lock is arranged rotationally fixed, then the rotation of the threaded spindle causes a displacement of the lock on the threaded spindle or, conversely, a displacement of the threaded spindle in the lock.

The advantage is a synchronization control for the telescoping or adjustment of the various stilts.

It is also advantageous if the controller is connected to a pressure control. The pressure control should ensure, while the device is moving, that all stilts are loaded with the same pressure on the ground. Druckstcucrung takes on the task of Suspension. The suspension prevents excessive stress on individual stilts and unnecessary twisting of the device.

The suspension can also compensate for additional driving loads that arise from hard / low-yielding wheels. Such wheels have a tread of hard rubber or even steel. Such wheels are so little yielding that the device during the pivoting movement for laying the film does not need to be additionally supported. This can reduce the construction costs and the operating costs.

For telescoping or adjustment, the suspension can be switched off and vice versa. It can also be connected electronically with a computer both together.

Optionally, the stilts according to the invention are locked in the working position of the device. The locking is intended to stiffen the device according to the invention in the working position in order to facilitate the positioning of the anchors and foils or other materials.

The locking can be done by bracing the stilts, e.g. with jaws.

Preferably, the locking takes place in hydraulic drive by blocking the hydraulic lines or by closing corresponding valves in the hydraulic lines. The control of the lock is preferably part of a common control.

The stilts are arranged at the free ends of pivoting arms. At the other end, the arms form the pivot bearing or the arms are pivotably mounted on one or in a frame of the device.

As stated above, the device according to the invention in addition to the pivoting stilts still has a pivoting device for a separate positioning of the working platform. Core of the pivoting device is an or several swivel arms. Preferably, two pivot arms are provided, which are arranged so that the working platform can swing through between the two pivoting arms.

To the further pivoting device may include a common pivot bearing for the two pivot arms. This may be advantageous if the pivot arms sit on a common pivot shaft and if a single pivot drive is provided for the common pivot shaft. Preferably, however, separate pivot bearings and separate drives are provided for the pivot arms. The two drives are preferably driven hydraulically. The hydraulics has a synchronous / synchronous control.

As with the stilts, other drives can also be used for the swivel arms for positioning the work platform.

At the free ends, the pivot arms may be interconnected by a rod to which the work platform may be suspended pivotally at one or more locations. This relieves the construction of the work platform.

Preferably, however, the work platform is designed to be self-supporting. The platform then has sufficient strength to be held at both ends of the pivot arms.

The work platform must carry the laying crew. Preferably, the platform also carries the tools for the laying crew. These may include: Anchor and accessory reservoirs, tools and tools for fitting and mounting the anchors and accessories, roll holders for film rolls and other material rolls, tools for laying foils and other materials, welding equipment, drilling equipment, power and other power generators Media.

The pivoting device can optionally be moved on the frame of the device or in the frame in the horizontal direction to the Swivel device one or the other tunnel side closer. For the displacement of the pivoting device similar equipment can be used as for the stilts.

Preferably, the pivoting device also has telescopic pivot arms for the movement of the working platform. For the telescopic pivot arms again similar devices can be used as for the stilts.

The platform can be arranged on the roller axle / shaft pivoting and hanging, which carries the role of the film / web to be laid.

Preferably, the role of keeping the material rolls is independent of the working platform attached to the pivot arms. Still more preferably, the role posture is also additionally pivotally arranged to provide the laying crew an optimal working position. The better the working conditions, the more quality can be expected from the installation.

The pivoting is achieved with additional pivot arms, so that the pivot arms for positioning the platform at the free end still have additional pivot arms for the roll holder. The additional swivel arms are moved on the same principle as the swivel arms for positioning the work platform.

The device according to the invention facilitates the handling of the film in a very considerable way. One device and two publishers can lay several hundred square meters of film per hour in a tunnel. That is, the laying performance can be increased with the inventive device per publisher by at least 10 times compared to conventional installation. The laying performance increases even higher, the greater the number of anchors to which the film must be attached. This is attributed to the fact that the film can be positioned with the device directly to the anchors, so that the Labeled film on the anchors and can be perforated quickly and accurately, then push the film with the holes on the anchor and lock with a fastener. This is partly attributed to the fact that the film can be positioned exactly at a weld or overlap.

For the positioning of the device according to the invention, the use of lasers and markings on the film webs is advantageous. The markings can be made of lines or dots with a contrasting color to the foil color. For black film, for example, white is a contrasting color.

For the task it is advantageous if the film take-off is speed-dependent and / or traction force-dependent adjustable and / or the drive of the film roll can be locked at any point and / or coupled out. It should be noted that the film can be deducted by hand, that the deduction should be made by the fact that only the roller drive is operated, but also a deduction should be possible that the film is fixed, for example, to anchors and that the role of the device is pivoted and rotated.

By controlling the speed and / or traction, an adaptation to the ability of the publishers can be made. Favorable is an overdrive for roller movement between two detents with a coarse position of the film and a subsequent fine adjustment of the film with a creep speed. Overdrive and creep are preferably adjustable together or separately. The advantage is a fast changeover from overdrive to creep speed, possibly also to intermediate gears. Meaning is also given for a changeover to change the direction of rotation. This applies to each of the gears.

The disengageability can also be used for fine adjustment of the film. The disengageability can also be used for role change.

Optionally, a locking of the role is provided in the respective working position. The locking of the roller allows working in any role position on the roll or on the film.

Due to the laying of the film, the film supply on the roll is used up. After exhaustion, new roll stock can be procured with a new roll or new roll stock can be wound up. The replacement bridges the winding winding process. However, this assumes that the film is delivered in rolls, which can be clamped between the pivot arms of the device.

Theoretically, this is feasible because the films are usually delivered in rolls and have a sleeve in the middle. The winding of the film on the sleeve takes place at the end of production at the manufacturer in a winder. In the winder, the sleeve is clamped and the film wound up tightly so that role also inclined or even can be held vertically, without the role changes in a detectable manner with the naked eye shape.

The roles are differentiated between the rollers to be moved by hand and the rollers to be moved by machine. The manually moving rollers must not exceed a maximum weight of, for example, 30 or 50 kg. Such roles are common in roofers who carry the roles on roofs or must move by hand. Such roles have a length of 1 meter or one of them slightly different length. The roll diameter is about 0.2 meters.

Starting with film rolls for landfill but roles have been developed with a length of 4 to 8 meters. Such rolls have a diameter of 0.5 meters and more. Your weight up to 1000 kg and much more depending on the length.

Although such roles can be readily used on the machine according to the invention. The invention has recognized that with a roll diameter of up to 300 mm, a much easier and faster laying of the film takes place. The length of the rollers can be 3 meters and more. Therefore, according to the invention for the Device according to the invention rolls with 3 meters and more Longer, but used with a maximum diameter of 300 mm. These roles still have a multiple of the manually movable weight due to the roll length.

Such roles can be obtained directly from the manufacturer. The special production causes additional costs. Therefore, according to the invention preferably a wrapping of the film roll is provided on a small diameter.

The wrapping can be done by means of a roll holder and the device itself by the device pulls the film from the roll holder and simultaneously wound. However, so that the capacity of the device according to the invention is not tied, a wrapping of the film rolls of large diameter to film rolls of smaller diameter is provided on a separate winding device.

The winding device has four receiving mandrels, two of which receive a sleeve between them. The mandrels are arranged so that the sleeves are parallel to each other.

Moreover, it is favorable if the receiving mandrels of at least one sleeve / roller are adjustable, so that the sleeve / roller can be pivoted out of the parallel.

Even with exactly parallel arrangement shows that the film is not always wound into a precisely cylindrical body. By slight pivoting in one or the other direction such effects can be controlled. In addition, guide discs on the spikes may be helpful in winding the film drawn from the supplied film roll into a cylindrical roll. When a desired roll thickness is reached, the film is severed between the two rolls.

The desired roles can be removed with a Hubgeschirr and a forklift from the wrapping device. The lifting harness may consist of loops and / or ropes, chains or bands. The bands are particularly favorable because they do not press into the role. The bands can be wrapped around the rollers and tight pulled / biased before the role of the mandrels is released. By biasing the release is facilitated and the role may at best fall slightly when releasing down. The release is done by retracting the mandrels.

After releasing and transporting the resulting film roll a new sleeve is placed between the mandrels. Thereafter, the wrapping process can be continued for a new desired film roll.

In order to bring the receiving mandrels with the sleeves into engagement or disengage, an axial movement of the receiving mandrels is provided. Conveniently at least at the top conical mandrels, which are arranged axially displaceable. The conical mandrels facilitate the insertion of the mandrels into the sleeves of the supply rolls. Optionally, the mandrels can also be provided with clamping means. The clamping means preferably engage inside the mandrels and are clamped there. These are electrical or mechanical or hydraulic or pneumatic drives, for example Spreitzbackcn as a clamping device.

Same mandrels are preferably provided on the pivot arms of the laying device, which receive the supply rolls for laying between them.

For wrapping all mandrels are rotatably mounted. Furthermore, a rotary drive is provided at least at the thorns where the withdrawn film to be wound. The drive can equally be designed electrically or mechanically or hydraulically or pneumatically. Conveniently, in turn, a regulation of the winding speed and the winding force.

The mandrels for the unwinding role are preferably provided with a brake. By braking the roll to be unwound, the necessary winding force can develop.

The brake can be designed as a simple shoe brake. Favorable is a brake with an adjustable braking force.

The wrapping device can also be advantageously used to add together any resulting film residues to form a longer film web or to weld them together. These film residues would otherwise have to be disposed of as waste.

The wrapping device is preferably designed to be mobile so that the device can be transported to the construction site.

Conveniently, a mounting of the wrapping on a trailer, so that the device is mobile and can be brought to any job site.

The wrapping device can be used alone for wrapping. But it is also possible to cooperate with the laying device in such a way that the film is pulled directly from the large supply roll onto a seated in the laying device sleeve and wound up there. Optionally then take place a weld with a remaining on the sleeve for winding rest.

As shown above, the device according to the invention can facilitate various jobs in the tunnel. Among the possible uses of the device according to the invention include maintenance and repair work in the tunnel.

Optionally, the device according to the invention can also be equipped with additional functions.

The additional devices may be boring mills for setting the anchors. In this case, preferably conventional boring with a drill pipe application. The boring machines are brought into the desired exact position with the pivoting device, so that the drill pipe can work from there in its axial direction into the mountains. In this case, the load from the backlash of the drilling means on the device can be minimized by the fact that the rotating drill pipe are acted upon pulsating by pneumatic or hydraulic drive with pressure. Optionally, the Drill rods are also pneumatically or hydraulically and repeatedly thrown against the mountains.

The reaction forces from this work can be absorbed attenuated.

Optionally, the laying tools of the portal-shaped laying device are replaced or finds the portal-like chassis of the laying device alone as a supporting structure for boring use.

Other work can also be carried out with the portal-shaped laying device or with its portal-shaped chassis. These include electrical work, maintenance, cleaning, repair work, installation of fans and their pipes and various other trades such as laying of reinforcements for concrete removal, applying a shotcrete layer.

The portal-shaped laying device can also carry all the equipment for wrapping large supply rolls to smaller supply rolls.

In the drawing, various embodiments of the invention are shown.

The device has four stilts 2, which are provided with rollers for the procedure below. The stilts 2 consist of tubes arranged inside each other with an internal drive and are telescopic. As a result, the height of the device can be changed.

At the same time the stilts 2 are fixed to pivot arms 3, which are pivotally mounted in a frame 1 of the device.

By pivoting, the width of the device can be reduced or increased as needed. The change in width may be required to adapt the device to the respective tunnel dimensions or to pass the device past obstacles in the tunnel.

Above the frame carries a pivoting device consisting of two pivoting arms 5, which are telescopic in the same way as the stilts. At the free end, the pivot arms 5 carry an axis for a film roll 6. On the axis hangs pivotally a working platform.

The Fig. 5 to 11 show a further embodiment in different views.

Fig. 5 and 6 show a perspective view of a device according to the invention in a tunnel next to a truck 16. From the tunnel, a contour 15 is shown. In addition, a contour 15a of another tunnel is shown in which can also be used with the device according to the invention.

The two tunnels 15 and 15a differ by a curved ridge of the tunnel 15 with respect to a horizontally extending ridge of the tunnel 15a and by different width and height.

To the device according to the invention includes a frame of longitudinal members 17 and headrests 18 and 33rd

At the four corners of the frame are telescopic. Stilts 1, 20, 21 and 22 articulated. The stilts have an L-shape. The long narrow leg forms the actual stilt, while the short leg forms the articulated connection with the frame.

In Fig. 5 is the joint of the articulated connection between the stilt 20 and the head carrier 33 designated 26.

The articulated connection of the stilts with the headrests serves to swing in and swing out the stilts. By swiveling increases the width of the device, in the extreme case in the Fig. 5 and 6 shown dimension. By pivoting the stilts, the width is reduced approximately to the width of the head carrier.

The stilts are pivoted in the embodiment in front of the head support and not laterally to the side members 17.

For pivoting power piston 25, 30 and 31 are provided. The power pistons are hinged at one end to a console.

With the other end they engage a pivotally mounted angle lever, which in turn is articulated to the associated stilt. Belonging to the stilt 20 angle lever is denoted by 27.

All stilts are telescopic. They consist of a tube in which further tubes are pushed into each other or from which the other tubes can be pushed out. The other tubes are designated at the stilt 20 with 20a and 20b. All tubes are square tubes, so that the tubes are arranged rotatably in each other.

In addition, all stilts are provided with limit switches, which give contact to the shutdown of the drives, if predetermined maximum positions or predetermined minimum positions are reached when extending the stilts and / or when shortening the stilts.

In the tubes an unrepresented power piston is arranged, with which the stilts are extended and retracted.

The device according to the invention also carries telescopic pivot arms 37. The pivot arms 37 are hinged at one end to the frame and carry at the other end of a working platform 36th

The telescoping of the pivot arms 37 is effected in the same manner as in the telescopic stilts. This also includes the use of power pistons, not shown, with which the pivot arms are extended or shortened.

Each pivot arm 37 is mounted individually. In the exemplary embodiment, each bearing consists of a pin attached to the pivot arm 37, which are received by a bearing block. The bearing block is displaceable on a rail 40. As a sliding drive is used at each bearing block in the embodiment, in turn, a power piston, in other embodiments, a mechanism, for example, a chain drive or a rack with a pinion. The chain drive then has like the pinion drive, which in turn is formed by a hydraulic motor.

The bearing block also carries a pivot drive 39 for the pivot arm, in the exemplary embodiment a rotary piston, in other embodiments, a lever which is moved by a power piston.

The pivot arms 37 are telescoped parallel as the stilts 19,20,21,22. The pivot arms 37 are simultaneously pivoted in parallel. The bearings belonging to the swivel arms are also moved in parallel. The parallel movement is effected by a synchronization control.

In addition, all stilts can be pivoted in parallel or individually or in groups.

The associated drives are connected in a common hydraulic circuit. Not shown valves regulate the flow of hydraulic fluid. The valves are controlled by a common computer.

The platform is designed to be self-supporting in the embodiment, so that the working platform 37 can be suspended at both ends at the free ends 41 of the telescopic pivot arms 37 pivotally. In the exemplary embodiment, this suspension is also combined with a rotary actuator. These are in turn Schenkmotore, at each end of the platform a swivel motor. The swivel motor allows to keep the platform always in the horizontal and at the same time rigid, so that the load on the platform can not lead to their unwanted swing.

In addition, a roller holder 43 is still provided at the free ends 41 of the pivot arms 37. To the roll holder 43 includes a frame of a extending between the free end cross member 45. In the embodiment, the roll holder is designed on two rolls of material, of which a roller 44 is shown.

Fig. 12 shows a wrapping device.

The rewinder has a sturdy frame 601 of square profile on which bearings 603 and 606 are mounted. Each bearing is provided with a power piston 605 and a mandrel 607. The power piston 605 is designed to displace the mandrel 607 in the axial direction. The displacement serves to insert the mandrel into the opening of a sleeve belonging to a supply roll 602 or 603 or to extract the mandrel from the sleeve.

The thorn is behind Fig. 13 provided with clamping jaws. The jaws are extended as soon as the mandrel reaches its end position in the sleeve. The jaws are retracted before the mandrel is moved out of the sleeve. The control of the mandrel takes place in the embodiment with hydraulic fluid, in other embodiments with compressed air or mechanically. In this case, the clamping jaw movement with the mandrel movement can be mechanically coupled so that the desired sequence of movements readily occurs.

In the embodiment, two bearings 604 are provided to receive a supply roll 602 of large diameter rotatably. From the large diameter supply roll, supply rolls 603 of small diameter are to be produced.

The supply roll 603 is rotatably supported at one end with a bearing 604 and at the other end with a mandrel 607, which is held in a housing 608 and is formed and moved in the same manner as the other mandrels. In addition, a motor 606 is provided, with which the roller 603 can be driven.

In the embodiment, the bearings for the roller 603 can be moved on the frame, so that the roller 603 is pivoted to the roller 602. This serves to adjust the wrapping process. The roller 603 is supposed to form exactly cylindrical at the ends. As far as hollow or syringe ends form, it can be counteracted with appropriate pivoting in one or the other direction.

Incidentally, a brake, not shown, is provided on the roller 602. A low braking effect is sufficient, which prevents the roller 602 from further unwinding when the roller 603 is stopped.
