Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is suspended and driven from a ceiling. In particular, the present invention relates to a device for assembling running rails for transportation, maintenance, and/or repair tracks that are suspended under platforms on artificial islands and driven in one direction.

In many cases, maintenance and/or repair work must always be carried out in the ceiling area of high indoor workshops. For this,
Truss structures are often used, which only provide an emergency solution. This is because the truss structure cannot avoid interference with the progress of work indoors.

Maintenance and/or repair operations on artificial islands, such as Pauling Island, on the underside of the platform, ie on the water side, are particularly difficult. Such artificial islands usually have at least one very large, horizontally extending waterside platform. This platform ho! - Keep the lower side at least temporarily spaced from the water surface. Whereas other areas of artificial islands for maintenance and/or repair work have relatively good accessibility;
It has proven particularly difficult to inspect and, if necessary, repair the underside of the platform, on the water side, which is exposed to high loads. For example, the underside of the platform must be periodically cleaned and repainted, and the conduits and mechanical units located under the platform must be managed and maintained.

PRIOR ART In order to carry out such work, according to German Patent Application No. 3,216,374, it is possible to provide a rail track on the underside of the platform and forcibly guide the work platform along this rail track. Already proposed.

All maintenance and/or repair work can be carried out without any problems from this platform1, since the rail track is laid out in a circular arrangement, so the platform can be installed at various locations under the platform. This is because it is travelable and therefore an additional auxiliary truss or auxiliary frame can be omitted. For example, routine tasks such as cleaning or painting the underside of the platform or maintaining piping provided under the platform can be performed whenever this is required.

Problem to be Solved by the Invention Regardless of whether a rail track with one running rail or a rail track with multiple running rails is provided on the underside of the platform, the mounting of the running rail is difficult. Traditionally, running rails have had to be installed directly during island construction, unless the work requires additional costs. This is done by moving the running rails in order to inspect the ceiling and possibly to be able to service and repair equipment installed on the underside of the ceiling, such as in particular energy transport and supply devices. This is inconvenient if it is to be attached to the ceiling later.

Therefore, the problem of the present invention is to provide a transport track that is suspended and driven;
To provide a device that allows the traveling rails of a maintenance track and/or a repair track to be easily and easily taken to an advantageous location on the ceiling or under a platform, especially later on.

Means for Solving the Problems The present invention, which has solved the above problems, is equipped with a workbench that can run along a traveling rail. A entrainably connectable positioning unit is provided, the positioning unit having an assembly table arranged at the end of the jib arm rotatable about a vertical axis, the assembly tape /l/ It is movable longitudinally along said jib arm as well as movable in height relative to said jib arm and further pivotable about a vertical axis.

In principle, a workbench that can move automatically and a positioning unit are connected. This positioning unit is operated in particular from the workbench as follows.

This means that a corresponding longitudinal section of rail track, for example in the form of a rail bar, is laid down on an assembly table at a loading point on the side of the platform or ceiling and then transported along the already laid rail track. The profit is manipulated so that it is added to the end of the trajectory. This maneuverability is achieved regardless of whether the rail track has only one running rail or two running rails arranged parallel to each other and spaced apart. A rotatable jib with a vertical axis in the middle allows the assembly table to always be in a position with a new rail or in which another rail section can be assembled.

Possibility to longitudinally move the assembly table relative to the free end of the zipper 1.

Adjustability of the height position and the possibility of pivoting around a vertical axis are obtained in all areas of the ceiling or under the platform, so that the rail track itself can be laid neatly in small curves without problems. Thereby, there is no need to provide assembly trusses, which require a very large amount of space and can also lead to work interruptions. In this case 1
The work platform can be permanently connected to the positioning unit.

Embodiments According to claim 2, it is advantageous if the running mechanism supporting the jib arm is connected to the running mechanism of the workbench by a suitable coupling member. By guiding the jib arm travel mechanism on the travel rail so that it does not tip over, new rails, or rail sections, can be easily accepted and simply transported to the assembly position.

irrespective of whether each rail section is straight or curved and whether it consists of one running rail or of a rail with two running rails extending parallel to each other. According to claim 3, a new rail segment can be accurately positioned at the end of an already laid rail track by means of a rail alignment device. The new rail section is now added and held fixed at the end of the already laid rail track in such a way that it is fixed in place to the ceiling or underside of the platform.

According to claim 4, the new rail section can be accurately positioned according to the extended shape of the rail track.

Thereby, the vertical pivot axis preferably extends in the vertical center plane of the rail track, so that a uniform pivot movement to the left or (or right) is possible, especially in the region of the bend. For positioning the alignment unit, it is sufficient to use one pivot cylinder, which is fixed to the pivot alignment unit on the one hand and to the traveling mechanism on the other hand. This swiveling cylinder is preferably hydraulically loaded.The swiveling cylinder has one
Energy is obtained from hydraulic devices forming part of the workbench.

According to claim 5, the rail alignment unit is provided with at least one rail receptacle which is movable in a direction perpendicular to the running rail by means of an adjusting cylinder. This adjusting cylinder is preferably hydraulically loadable. By means of this adjusting cylinder and by means of a rail receptacle, a new rail section (single running rail or parallel running rail) is in each case precisely added to the end of an already laid rail track.

At this time, the rail receiving portion is designed to match the cross-sectional shape of the running rail. Of course, it is sufficient that the rail receiving portion surrounds the lower longitudinal edge of the running rail.

If the rail track consists of two running rails running parallel to each other and spaced apart, the adjusting cylinder extends between the two running rails and is connected to a rail receptacle of each running rail. In this case, the housing of the adjusting cylinder is connected to one rail receptacle, and the screw I/O rod is connected to the other rail receptacle.

Advantageous embodiments of the invention are described in claim 6. The housing movable along the jib arm is preferably supported on rollers. For this purpose, the main longitudinal sections of the jib arm were arranged side by side at a distance from each other. It is formed by two profiles that are U-shaped in cross section, in which a roller is engaged which is supported inside the casing.

The casing is preferably movable by means of a hydraulically loaded slide cylinder and is thereby positioned precisely 61f, in which case the slide cylinder is aligned with the

In this connection, the embodiment according to claim 8fA assists in the precise positioning of the rail sections. In this case, a guide bushing is provided in the center of the assembly double, and the guide bushing is oriented in a vertical direction passing through the rotating orbit ring and the base frame, and surrounds the takaido pin in a cardan-like manner.

This guide pin is fixed to the jib casing.

Each rail segment is successfully received in the loading position and from the loading position the already laid rail lI! For orderly positioning along the lL path and at the end of the rail track,
According to the embodiment of claim 9, the assembly table is provided with a locking device for the running rail stop. The locking device preferably has a hydraulically loaded clamping cylinder which, if appropriate, incorporates at least one spacer web and which at least temporarily secures each rail section and which sets the assembly A′. ! It is in a position where it is neatly prepared for dero.

According to claim 10, the working platform is moved from a prepared position below its running mechanism, with each folded running rail section extending to the ceiling of the hall or the underside of the Cyranodo platform, each corresponding to the preceding rail section. Format (screw,
rivet.

It can be rotated upwards to the extent that it is added with 1 concubine). In the case of 1, the working Cyranodo home can be configured to allow prescope movement.

Although the pivoting movement of the working cylinder home can be carried out in different ways, the embodiment according to claim 11 is particularly simple and requires less maintenance. In this case, the swivel cylinder is hinged on its casing to a parallelogram linkage, and its piston rod is hinged to a running mechanism of the work platform.

In order to adapt to different radii of curvature, the embodiment according to claim 12 is used. In this case, if a rail track consisting of two mutually parallel running rails is used, the drive is guided along only one running rail.

According to the illustrated embodiment, the rail track δ consists of two running rails 5 that extend parallel to each other, each of these two running rails 5 having a letter-shaped cross section.

The rail track 3 is divided into individual rail sections 6, 7 (see FIGS. 1 and 6). The length of the straight rail section 6 is, for example, 3 m. The curved rail section 7 is
It has a range based on the curve to be formed.

A positioning unit 8 is provided in order to lay the rail track δ on the lower side 2 of the plant board, and this positioning unit 8 can be connected to and guided by a working joint that can run along the traveling rail 5. The working station consists of a longitudinally movable working platform 10 with a guardrail 9 and a running mechanism 11 guided by a running rail 5 (see FIG. 1). This traveling mechanism ll itself consists of a drive section 12 and a rotating orbit ring 14.
It is divided into a support part 13 and a guide part 15.

Since the drive part 12, the support part 13, and the guide part 15 are hinged to each other, it is possible to travel around narrow curves (see FIG. 2). When the vertical pivoting movement of the working platform 10 relative to the traveling mechanism 11 is at least one parallelogram link mechanism 16, the casing 18 of the pivoting cylinder 17 is hinged to the link 19, and the piston rod 20 supports the traveling mechanism 11. It is hinged to section 13.

As indicated in FIG. 1 by dash-dotted lines, a working platform 10 can be pivoted/displaced relative to a support 13 about a vertical axis 21 and in a vertical plane, and Being telescopically movable, it can be moved to any working position below or next to the positioning unit 8 (which will be explained in more detail below).

The positioning unit 8 mainly consists of a jib arm 23 forming a component of the running mechanism 22, which is guided against tilting on the running rail 5, and an assembly table 24 for receiving the rail sections 6, 7. .

As shown in FIGS. 1 and 2, the traveling mechanism 22 of the positioning unit 8 can be hinged to the drive part 12 of the traveling mechanism 11 of the workbench 4. ]] and 22, similarly, no problem occurs when traveling on a curve.

A rail alignment device 26 (see FIGS. 1, 2, and 5) is provided on the end surface side of the positioning unit 80 and the travel mechanism 22. This rail alignment device 26 is connected to the traveling mechanism 22 via a vertical shaft 27 and a swing cylinder 28 that can be loaded with hydraulic pressure.

For this purpose, the rail alignment device 26 is provided with two rail receiving portions 29 which can be replaced at a position orthogonal to the running rail 5.
is under the action of a hydraulically loadable adjusting cylinder 30.

The jib arm 23 has a casing-like longitudinal section δ directed obliquely downward and a horizontal longitudinal section 32 extending parallel to the horizontal axis 2. The longitudinal section 32 consists, for example, of two mutually reinforcing U-shaped profiles δ3 (see FIGS. 1-1).

This zero-shaped profile 33 is surrounded by a console-like casing 34 and is overlapped by four. This housing 34 has a guide roller 35 on the inside, which guide roller 35 is forcibly guided in the longitudinal direction of the zero profile 33.

A hydraulically loadable slide cylinder 36 is used to move the casing 34 in the longitudinal direction. The casing of this slide cylinder 36 is pivotably fixed to the obliquely downwardly directed longitudinal section 31 of the jib 23, and the piston rod of the slide cylinder 36 is pivotably fixed to the casing δ4. By applying a corresponding load on the slide cylinder 36, the casing 34 is moved along the jib arm 23 and positioned at the desired position.

The console-shaped gauging 34 includes a rotary orbit ring 3
8 and a support frame 37 for receiving an auxiliary rotary piston cylinder (not shown in detail) is fixed so as to be pivotable about a vertical axis 25 (see FIGS. 1 and 3). This base frame 3'17i is of rectangular design and has at each corner a hinge point 39 for a piston rod 40 of a vertically configured and hydraulically loaded lifting cylinder +1; The casing 42 of the lifting cylinder 41 is hinged to the assembly table 24. This assembly table 24- also has a rectangular configuration like the base frame 37. A guide bin 43 extends from the console-shaped casing δ through the base frame 37 and the assembly table 24 at the center. A guide bush 4 is provided on the standing table 24 (see Fig. 3), and this guide bush 44 allows limited spatial movement with respect to the assembly 24u and the base frame 37K. be able to.

Then, by means of the lifting cylinder 41, the rail sections 6 and 7 that are to be defined are given to the rail section 6 and 7. , etc. - The assembly table 24 can be moved to various desired high positions.

] Consists of a tensioning cylinder 47 capable of carrying a negative load, not shown in detail, for possibly transporting the rail sections 6, 7 and for fixing them between the rails 5 of the platform lower side 2. A spacer web may also be provided. This spacer web can be removed again after the rail 5 has been fixed.

The movement of the rail sections 6, 7 takes place as follows.

The positioning unit 8 connected to the working station is moved into the loading position next to the platform 1 (see FIG. 6). This loading position is the same as the compensation device 48 for the working hand and positioning unit 8. The loading unit 8 is indicated by a dash-dot line in FIG. In the loading position, the jib arm 23 is relative to the traveling mechanism 22.

And advantageously, the working platform 10 is pivoted by approximately 90° relative to the schematically illustrated support 13. A straight rail section 6 or a curved rail section 7 from the platform 1 of the artificial island is thus brought onto the assembly table 24 and secured from the working platform 10 with the aid of the locking device 5.

The jib arm 23 and the working platform 10 are then swiveled into the traveling position, and the mutually connected working arm and positioning unit 8 are moved to the assembly position.
