Title:

System roller scaffolding for shaft heads in elevator systems

Information about the genus:

The system roller scaffold for the shaft heads of elevator systems is intended primarily to reduce the costs of previously individually produced roller scaffolds and to be easier to assemble due to its lower weight. ■ ■ ■

This is achieved by using a few standardized system components such as roller cages type 1 and 2, support beam supports, angle pieces, rope protection, dead center suspensions type 1 and 2 and counter plates type 1 and 2 together with commercially available connecting elements the roller frame and the dead center suspension can be adapted to almost any shaft dimension by simply sawing the load-bearing components such as support beams and spacer bridges to length.

State of the art:

Until now, elevator companies and component manufacturers for elevator systems in which supporting cables for cabins and counterweights are redirected via cable pulleys in the shaft head have repeatedly planned, designed, drawn and manufactured new roller frames individually for each construction project.

Criticism of the state of the art:

This has led to high costs in the technical office, in the workshop and during assembly. Due to the individual construction of these roller scaffolds and dead-center suspensions, errors can occur again and again, which then turns out during assembly that the components do not fit together. This leads to further costly remedial work. In addition, these individually constructed roller scaffolds are usually very heavy and therefore difficult to assemble.

Task :

The aim and purpose of this invention is therefore to limit all functional components to a minimum of variations. At the same time, these components should be combinable with and among each other as system components and should fit almost any shaft situation as well as shaft depth and shaft width. The low weight of the individual components and the ability to move the system components during assembly make assembly considerably easier. By using the recurring system components and the advantage that only the support beams and spacer bridges have to be cut to length on a commission basis, the manufacturing costs should be drastically reduced compared to individual designs.

Solution:

■These tasks are solved in the system roller frame for shaft heads in elevator systems by the characterizing features of claim 1.-" ■

Further embodiment of the invention:

The further embodiment of the invention is solved by the characterizing features of claims 2 to 8.

Achievable benefits:

Due to the series production of a few system components and the advantage of only having to cut the support beams and spacer bridges to length, the costs for the system roller frame are significantly lower than for individual production. In addition, the position of the rollers and the number of rollers as well as the position of the dead center suspension can be individually adapted to almost any shaft situation, since all components can be moved on the shaft.

are attached to support beams which are cut to length on a commission basis.

The low weight of the individual system components and the adaptation to even the narrowest shaft heads and shaft layouts make the system roller scaffold extremely easy to assemble. It can be used for new construction and modernization and is suitable for arrangement parallel, at right angles or at an angle to the shaft walls.

Only the support beams are individually designed according to the load case and sawn to fit the shaft dimensions. The series production of the system components enables the shortest possible delivery time, "just-in-time" to the construction site.

Description of one or more embodiments:

The various embodiments of the invention are shown in the drawings in Figures 1 to 6 and described in more detail below:

The invention works according to the following principle:

The system roller frame for shaft heads in elevator systems consists of a few system components and commercially available connecting elements. The system components, which are manufactured in series and are therefore inexpensive to manufacture and can always be called up at short notice as stock items, include the following components: roller cage type I (1), roller cage type II (2), support beam support (3), rope protection angle piece (4), dead center suspension type I (5), dead center suspension type II (6), counter plate type I (7), counter plate type II (8).

Depending on the individual construction project, only the spacer bridge (.11) and support beams (16) components need to be sawn to length. Further processing steps such as welding, drilling, edging, etc. are not necessary. These components are standard rolled profiles.

The dimensions of the support beams (16) are individually designed according to the load case.

All other components of the roller scaffolding system are commercially available connecting elements. The components of the roller scaffolding system are described in more detail in Figures 1, 5 and 6. 175

On the opposite side of a roller scaffold there is usually a so-called dead center suspension (6) in the case of a 2:1 lift suspension. This is where the ropes are attached, which

under the cabin. This can be found in Figure 6.

All profiles used can be rolled profiles as well as folded sheet metal profiles.

The combination, position and number of rope pulleys (17) and dead-center suspensions (5, 6) is unlimited and can be adapted to any shaft situation. Figures 1 to 4 show variations with one pulley (17), two pulleys (17), two pulleys (17) with dead-center suspension (5) and three pulleys (17) with dead-center suspension (5), with the third pulley (17) being attached below the other two with another support beam (16). The third pulley (17) can also be placed on another support beam (16) next to the first two pulleys (17). The rope pulley (17) can also be placed on two support beams (16) so that the ropes can be guided between the support beams. See Figure 5. .

The roller cages (1, 2) are attached using roller suspensions (13), consisting of threaded rods, secured by, for example, castle nuts with split pins or other locking nuts.

The same applies to the dead-center suspension (5, 6), which is attached to the support beam (16) by so-called dead-center suspensions (14). The support beams (16) rest at their respective ends on support beam supports (3), which rest on the masonry of the elevator system with sound and vibration insulation. Counter plates (7, 8) are used to attach the roller cages (1, 2) and dead-center suspensions (5, 6), which are mounted on or under the support beam (16). The roller cages (1, 2) can also be attached to the support beam (16) using clamping plates (15). To ensure that the support beams (16) do not slip on the support beam supports (3), these are also attached using clamping plates (15). In order to be able to individually maintain the distance between the incoming rope and the outgoing rope via two rope pulleys (17), a spacer bridge (11) consisting of a square tube with a threaded rod is placed between two pulley cages (1, 2).

The core is placed between two roller cages (1, 2). This square tube simultaneously absorbs the forces that occur.

The ropes are protected from jumping off by rope protection devices (9). These are kept at a distance using angle pieces (4) via threaded rods (12) on the roller cages (1, 2) that can be adjusted to different roller diameters. Another rope protection, type II (10), is installed in the roller cage (1) for smaller rollers (17).
