Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a transportation, maintenance and/or The present invention relates to a device for assembling running rails for repair tracks.

Often in high indoor workshop ceiling ranges,
Maintenance and/or repair work always needs to be carried out. A truss structure is used for this purpose, but
This truss structure is often only a makeshift solution due to its obstacles in indoor operations. Maintenance and/or repair operations on artificial islands, such as Boring Island, on the lower side of the platform, ie on the water side, are particularly difficult. Such artificial islands are usually provided with at least one very large horizontally extending waterside platform, the underside of which is at least temporarily spaced from the water surface. It's getting old. While other areas of the artificial island for carrying out maintenance and/or repair work are relatively accessible to workers,
It is 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 underneath the platform must be managed and maintained.

[Conventional technology]

In order to carry out such work, according to German Patent Application No. 3216374,
It has already been proposed to provide a rail track on the underside of the platform and to forcibly guide the work platform along this rail track. From this workbench all maintenance and/or repair work can be carried out without any problems. This is because, since the rail track is laid in a circular arrangement, the platform can be run at various points on the underside of the platform, so that additional auxiliary trusses or frames can be dispensed with. be. For example, routine tasks such as cleaning or painting the underside of the platform or maintenance of piping provided under the platform can be carried out whenever this is required.

[Problem to be solved by the invention]

Regardless of whether the underside of the platform is provided with a rail track with one running rail or with several running rails,
Until now, the running rails had to be installed directly during the production of the artificial island, unless the running rail installation required additionally high costs. This is used for driving in order to inspect the ceiling and in particular to be able to maintain and repair equipment installed on the underside of the ceiling, such as energy transport and supply devices. This is inconvenient if the rail is to be attached to the ceiling later.

SUMMARY OF THE INVENTION It is therefore an object of the invention to mount the running rails of a suspended and driven conveyor track, maintenance track and/or repair track in a particularly easy and simple manner afterwards at the ceiling or the underside of the platform at the respective advantageous location. The objective is to provide a device that can do this.

[Means to solve the problem]

According to the present invention that solves the above problems, a positioning unit is provided for the traveling rail to be laid, which is connected to a workbench that can travel along the existing traveling rail, and the positioning unit has an assembly table for supporting the running rail to be laid, which is disposed at the end of a jib arm rotatable about a vertical axis, and the assembly table extends longitudinally along the jib arm. It is movable in direction as well as in height relative to the jib arm, and further pivotable about a vertical axis.

[Effect]

A self-propelled workbench is connected to a positioning unit, which is operated in particular from the workbench in the following manner. This means that a corresponding longitudinal section of the rail track, for example in the form of a bar rail, is laid down on an assembly table at a loading point on the side of the platform or ceiling and then transported along the existing rail track to the existing rail track. It is manipulated so that it is added to the end of. This maneuverability is achieved regardless of whether the rail track has only one running rail or two running rails arranged parallel to one another and spaced apart. A jib rotatable about a vertical axis can always bring the assembly table into a position with a new rail or in which another rail section can be assembled.

The possibility of moving the assembly table in the longitudinal direction relative to the free end of the jib arm, the possibility of adjusting the height position and the possibility of pivoting about the vertical axis are possible in all areas of the ceiling or underside of the platform. As a result, the rail track itself can be laid neatly within small curves without any problems. Thereby, there is no need to provide assembly trusses, which require a very large amount of space and often cause work interruptions. The work platform can be permanently connected to the positioning unit.

According to claim 2, it is advantageous if the running mechanism supporting the jib arm is connected to the running mechanism of the working platform by means of a suitable coupling member. By guiding the jib arm traveling mechanism with the traveling rails so that it does not tilt, it is possible not only to receive a new rail, that is, a rail section, without any problem and transport it to the assembly position, but also to ensure that each rail section is straight or straight. regardless of whether it is curved and regardless of whether the rail section consists of one running rail or of a rail with two running rails extending parallel to each other,
It is also possible to precisely position each rail section.

According to claim 3, a new rail section is accurately added to the end of the existing rail track through a rail alignment device for the traveling rail to be laid, and this new rail section is is held fixed at the end of the existing rail track until it is properly fixed 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 right is possible, in particular in the region of the bend. For positioning the rail alignment unit, one pivot cylinder, which is fixed on the one hand to the pivot alignment unit and on the other hand to the traveling mechanism, is sufficient. This pivot cylinder preferably extends laterally of the vertical pivot axis. This pivot cylinder is preferably hydraulically loaded. The swivel cylinder obtains its energy from a hydraulic device forming a component of the work platform.

According to claim 5, the rail alignment unit includes at least one rail receptacle for the running rail to be laid, which is movable in a direction perpendicular to the existing running rail by means of an adjusting cylinder. A section has been established. This adjusting cylinder is preferably hydraulically loadable. By means of this adjusting cylinder and by means of the rail receptacle, a new rail section (single running rail or parallel running rail) can be precisely added to the end of the existing rail track. At this time, the rail receiving portion is matched to 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 piston rod to the other rail receptacle.

Advantageous embodiments of the invention are defined in claim 6.
It is described in the section. The housing, which can be moved along the jib arm, is preferably supported on rollers. For this purpose, the main longitudinal part of the jib arm is formed by two profiles with a U-shaped cross section, arranged side by side at a distance from each other, in which a casing is inserted. Internally supported rollers are engaged.

The housing is preferably movable by means of a hydraulically loaded slide cylinder and is thereby accurately positioned. In this case, the casing of the slide cylinder is hinged to the jib arm, and the piston rod is hinged in the center of the casing. A rotating orbit ring is arranged in the upper part of the casing, in which a rotating piston cylinder is integrated, so that the assembled cable can be rotated about the vertical axis relative to the casing, especially by means of hydraulic energy. Forced to turn.

According to claim 7, each rail portion can be accurately positioned even under difficult assembly conditions. In this case, a lifting cylinder with a piston rod is pivotably mounted in each corner area of the base frame, whereas the housing of the lifting cylinder is pivotably fastened to the assembly table. By correspondingly loading the lifting cylinders, each rail section oriented on the assembly table can be brought precisely into the predetermined assembly position and connected to the existing rail track or mounted on the ceiling or underside of the platform. Fixed.

Further, according to the embodiment described in claim 8, a more accurate positioning operation of the rail portion can be obtained. In this embodiment, a guide bushing can be provided in the center of the assembly table, which surrounds a vertically disposed guide pin passing through the rotary track ring and the base frame in a cardanic manner. This guide pin is also fixed to the jib casing.

According to the embodiment of claim 9, each rail section can be satisfactorily received in the loading position and positioned from the loading position in an orderly manner along the existing rail track and at the ends of the rail track. For example, the assembly table is provided with a locking device for holding the running rail to be installed. This locking device preferably has a hydraulically loaded tensioning cylinder. This clamping cylinder, optionally incorporating at least one spacer web, is provided for at least temporarily fixing the respective rail sections and orderly assembling them.

According to claim 10, the working platform can be moved from a ready position below its traveling mechanism by:
Each new running rail section extends to the platform ceiling or underside of the platform and can be pivoted upwards to the extent that it is attached to the preceding rail section in a suitable manner (screws, rivets, welding). In this case, the working platform can be designed to be telescopically movable.

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

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

(See Figure 1). The traveling mechanism 11 itself is divided into a drive section 12, a support section 13 provided with a rotating track ring 14, and a guide section 15. Drive section 12, support section 13, and guide section 1
5 and 5 are hinged to each other, so that it can also drive around narrow curves (see Figure 2). The vertical pivoting movement of the working platform 10 relative to the traveling mechanism 11 is effected by means of a parallelogram linkage 16 and at least one pivoting cylinder 17. The housing 18 of the pivoting cylinder 17 is hinged to a link 19, and the piston rod 20 is hinged to a support 13 of the running mechanism 11.

1, the working platform 10 can be pivoted to be displaced about a vertical axis 21 and in a vertical plane with respect to the support 13, and also has a telescope. Since it is movable, it can be moved to any working position below or next to the positioning unit 8 (which will be explained in more detail later).

The positioning unit 8 mainly consists of a jib arm 23 forming a component of the traveling mechanism 22, which is guided so as not to tilt on the traveling rail 5, and an assembly table 24 for receiving the rail parts 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, so that these two traveling mechanisms 11 and 22 Similarly, there are no problems when driving around curves.

A rail aligning device 26 (see FIGS. 1, 2, and 5) is provided on the end side of the traveling mechanism 22 of the positioning unit 8.
(see figure). This rail alignment device 26 is pivotally connected to the traveling mechanism 22 via a vertical shaft 27 and a hydraulically loadable pivot cylinder 28 . By means of the rail alignment device 26, the terminal ends of the rail sections 6, 7 which are to be brought into contact with the already laid rail track 3 are accurately aligned with the terminal end of the rail track 3. For this purpose, the rail alignment device 26 is provided with two rail receptacles 29 which are displaced perpendicularly to the running rail 5 and which are connected to hydraulically loadable adjusting cylinders. It is under the influence of 30.

The jib arm 23 has a casing-like longitudinal part 31 directed diagonally downward and a platform 2.
It has a horizontal longitudinal portion 32 extending parallel to the horizontal direction. The longitudinal section 32 consists, for example, of two mutually reinforcing U-shaped profiles 33 (see FIGS. 1 to 4). This U-shaped profile 33 is surrounded by a console-shaped casing 34. This housing 34 has a guide roller 35 on the inside, which guide roller 35 is forcibly guided in the longitudinal direction of the U-shaped 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 portion 31 of the jib 23, and the piston rod of the slide cylinder 36 is pivotably fixed to the casing 34. By applying a corresponding load on the slide cylinder 36, the housing 34 is moved along the jib arm 23 and positioned at the desired position.

A base frame 37 is fixed to the console-shaped casing 34 so as to be pivotable about the vertical axis 25 with the aid of a rotating orbit ring 38 and a rotating piston cylinder (not shown in detail). (See Figure 3). This base frame 37 is approximately square in design and has hinge points 3 at each corner for a piston rod 40 of a vertically configured and hydraulically loaded lifting cylinder 41.
9, and the casings 42 of these lifting cylinders 41 are hinged to the assembly table 24. Like the base frame 37, this assembly table 24 is also configured in a rectangular shape.
A guide pin 43 extends from the console-shaped casing 34 through the base frame 37 and the assembly table 24 at the center. The assembly table 24 is provided with a guide bush 44 (see FIG. 3), and this guide bush 44 allows the assembly table 24 to be attached to the base frame 3.

In order to secure the rail parts 6, 7 for assembly on the assembly table 24, two locking devices 45 for the running rail 5 to be laid are provided (see FIGS. 1 and 3). These two locking devices 45 include a laterally movable tensioning clamp 46 and a hydraulically loadable tensioning cylinder 4.
7, and if necessary spacer webs, not shown in detail, may be provided for transporting the rail sections 6, 7 and for fixing them between the rails 5 on the lower side 2 of the platform. . This spacer web can be removed again after the rail 5 has been fixed.

The movement of the rail sections 6, 7 is carried out as follows.

A positioning unit 8 connected to the workbench 4 is moved into a loading position next to the platform 1 (see FIG. 6). This loading position is determined by the compensating device 48 for the work platform 4 and the positioning unit 8.
