Description

The present invention relates to a method for starting up an elevator installation according to the preamble of patent claim 9 and a mounting kit for mounting a sliding guide device to an elevator cage of an elevator installation according to the preamble of patent claim 1.

For guiding the car in elevators with guide rails arranged on the elevator cab guide shoes are used, which are designed either as a roller guide shoes or sliding guide shoes. In the first case, rollers are usually provided with so-called two-dimensional or three-dimensional guidance, which roll on corresponding guide surfaces of the guide rail. In the second case, the sliding guide shoes are provided with sliding inserts, which slide with little play along the guide rails, so that they give the car during the vertical conveying movement a guide in the horizontal plane.

The following is primarily about elevator systems with guide rails and corresponding Gleitführungsschuhen for horizontal guidance of the elevator car along the substantially vertical guide rails.

In order to ensure a quiet and possible shock-free running of the elevator car in such elevator systems, materials are used as sliding inserts, which are typically softer than the material of the guide rails. In addition, when choosing the materials, it is taken into account that as little guide rail wear as possible occurs during operation of the elevator installation.

Therefore, materials such as polyurethane or polyethylene are currently preferably used in the sliding inserts. There are embodiments in which the Kunststoffgleiteinsätze are interchangeable, since such sliding inserts are subject to wear. A corresponding example is the German utility model DE 203 15 915 U1 refer to.

Elevator systems are nowadays often already installed during the shell phase in a building and taken during the interior work already provisionally in operation. Now it comes in these cases after the later official commissioning of the corresponding elevator system, or after the Bauabnahme, during operation of the elevator system to disturbing noise and vibration, resulting in unsatisfactory running behavior. Studies show that these disorders can be caused on the one hand by contamination of the guide rails and / or the sliding inserts and on the other hand by damage to the sliding surfaces of the guide rails and / or the sliding inserts and assembly inaccuracies.

• nicht ausreichende Qualität der Gleitflächen der Führungsschienen (zum Beispiel Schuppenstruktur);
• Beschädigungen der Gleitflächen der Führungsschienen wegen unsachgemässem Transport oder unvorsichtiger Montage;
• Ablagerung von feinkörnigem Baustaub, Mörtelresten oder dergleichen auf den Gleitflächen. Diese Faktoren sind insofern besonders problematisch, da es -verursacht durch diese Ablagerungen- beim Entlanggleiten der Führungsschuhe zu Riefenbildungen an der Gleitfläche oder zu Beschädigungen der Gleiteinsätze kommen kann. Auch können Mörtelreste oder auch Metallspäne, welche beim Montieren der Aufzugsanlage entstehen können, in die Gleitfläche des Gleiteinsatzes eingedrückt werden;
• Überreste von Schutzschichten, Schutzanstrichen oder Fett- bzw. Ölresten auf den Gleitflächen der Führungsschienen.

Among other things, the following factors can have an influence on the noise and vibration behavior of newly installed elevator systems:

• insufficient quality of the sliding surfaces of the guide rails (for example scale structure);
• Damage to the sliding surfaces of the guide rails due to improper transport or careless installation;
• Deposit of fine-grained construction dust, mortar residues or the like on the sliding surfaces. These factors are particularly problematic in that it caused by these deposits when sliding along the guide shoes to scoring on the sliding surface or to Damage to the sliding inserts can come. Also mortar residues or metal chips, which may arise during installation of the elevator system, are pressed into the sliding surface of the sliding insert;
• Remains of protective layers, protective coatings or grease or oil residues on the sliding surfaces of the guide rails.

These factors not only have a negative influence on the running behavior at the moment of commissioning, but they can damage or influence the entire sliding system in such a way that the running behavior is permanently disturbed.

The object of the invention described below is therefore to avoid the mentioned disadvantages of the prior art and to provide an improved solution.

In particular, it is regarded as an object of the invention, the running behavior of newly installed elevator systems, or of elevator systems that have been exposed to dirt or damage to the sliding system as part of a complex total revision after completion of the work, or before a transfer of the elevator system to a customer , to improve.

• einen Montagesatz zur Montage einer Gleitführungsvorrichtung nach dem kennzeichnenden Teil des Patentanspruchs 1, und
• ein Verfahren zur Inbetriebnahme einer Aufzugsanlage mit einer Aufzugskabine und Gleitführungsvorrichtungen

gelöst.This object is achieved by the invention

• a mounting kit for mounting a sliding guide device according to the characterizing part of patent claim 1, and
• a method for operating an elevator installation with an elevator car and sliding guide devices

solved.

The present invention has the advantage that after completion of the dirt-causing work or work that can lead to damage to the sliding system, the sensitive parts of the sliding system, namely the sliding inserts, can be replaced in a few simple steps. Thus, with the official commissioning, or the final acceptance of the system from the beginning, the desired smoothness can be guaranteed.

Further details, features and advantages of the invention will become apparent not only from the dependent claims and the features to be taken from them - alone and / or in combination - but also from the following description of preferred embodiments.

Fig. 1 shows a highly schematic, not to scale top view of a portion of an elevator installation with an elevator car 14, which is guided between two laterally arranged guide rails 11 vertically in a lift shaft, not shown. In order to ensure the vertical guidance, four (or more) sliding guide devices 10, which have a guide shoe 12 with a U-shaped receiving area for sliding inserts 3, 13, are generally fastened to the elevator car 14. Two of these sliding guide devices 10 are arranged in a lower region of the elevator car 14 and two more are arranged in an upper region of the elevator car 14 Fig. 1 the sliding inserts 3.13 are indicated by U-shaped thick black lines. The guide rails 11 typically have a T-shaped cross-section and the sliding inserts 3, 13 grip around the "trunk" of the T-shaped guide rails 11, two opposing surfaces and a base surface of the slide inserts 3, 13 along the outwardly facing side surfaces and an outer end face of the "trunk" of the T-shaped guide rails 11 slide. The two opposing surfaces and the base surface of the sliding inserts 3.13 have so-called sliding zones. The term sliding zone is used for those areas of the sliding inserts 3, 13 that interact with the guide rail 11 (sliding or sliding).

Before discussing details of various embodiments, the principle of the invention will be explained. According to the invention, during the construction phase, ie during the phase where soiling and / or damage can occur on the sliding guide device 10, special assembly sliding inserts 13 are used. These mounting slide inserts 13 be replaced before the handover, respectively Bauabnahme, by the actual sliding inserts 3, which are designed specifically for continuous use and whose material or materials are designed for a reduction of operating noise and vibration. The features of the special mounting slide inserts 13, however, are chosen so that the cleaning function and accurate guidance of the elevator car with respect to the driving characteristics (noise and vibration) have priority.

The term mounting slide insert 13 will be used hereafter to provide a clear linguistic distinction from conventional slide inserts, also referred to herein as standard slide inserts 3. The choice of these specific terms should not be understood as limiting.

In the FIGS. 2A and 2B Details of a first embodiment are shown.
Fig. 2A is an exploded view of a sliding guide device 10. The sliding guide device 10 comprises a guide shoe 12, whose housing, or body, is shaped so that it has an elongated, U-shaped recess or longitudinal groove 17. This longitudinal groove 17 is formed according to the invention so that a standard sliding insert 3 or alternatively according to the invention, a mounting slide 13 can be used.

The guide shoe 12 is seated with its rear side 16 on the elevator car 14 or is otherwise mechanically connected to the elevator car 14. During assembly of the elevator installation, according to a prior art, typically the standard sliding insert 3 is first inserted into the guide shoe 12 and only then are these mounted as a unit on both sides of the elevator car 14 in such a way that the "trunk" of the guide rails 11 between the Glide zones of the standard sliding inserts 3 is located.

However, the guide shoes 12 are designed so that during the construction or repair work temporarily, that is, in the period before a final commissioning of the elevator system, or in connection with the completion of a construction or revision phase, the Montagegleitsätze 13 be used. In Fig. 2B an example of such a mounting slide insert 13 is shown. It can be inserted or inserted instead of the standard sliding insert 3 in the guide shoe 12 and fixed or fixed there. For fastening, small fastening means 15 are used in the embodiment shown, which are each fastened at the lower and upper end of the guide shoe 12 by means of screws, as in FIG Fig. 2A can be seen and as it is known from the attachment of standard sliding 3.

Now that the dirt- and dust-causing work, or the work that can lead to damage of the sliding guide device 10, completed, the fastening means 15 are released and the Montagegleiteinsätze 13 are removed. Then the standard sliding inserts 3 are mounted.

In the in the FIGS. 2A and 2B As shown embodiment, this disassembly and assembly goes without the guide shoes 12 would have to be dismantled from the elevator car 14 or otherwise removed. The sliding inserts 13 or 3 to be mounted, depending on the situation, can be pushed along the guide rail 11 from above or below into the longitudinal groove 17 and screwed or clamped there by the fastening means 15.

It is particularly advantageous that using the mounting slide 13, the elevator car such as Türkoppelungsteile and manhole installation such as position sensor can be accurately mounted and aligned. The mounting slide 13 is particularly suitable for this purpose, since it has little play and is not very elastic. A standard sliding insert 3 as it is commonly used, on the other hand, is elastic, since it should absorb driving inaccuracies as smoothly as possible.

It is now important that the material of the mounting track zone of the mounting slide 13 is selected so that when moving the Elevator car 14 along a guide rail 11 results in a cleaning action on the guide rail 11.
In addition, the mounting siding zone of the mounting slide insert 13 may have structural surface features to enhance or enhance the cleaning effect. In Fig. 2B an embodiment is shown in which a plurality of horizontal bores or milling recesses 20 are provided in the region of the mounting track zones. In addition or alternatively, by attaching phases 22 (as deflectors or scraping edges) in the entry and / or exit area, it is ensured that residues and foreign bodies on the guide rails 11 are scraped off. In Fig. 2B is such a phase 22 visible at the top right.
In an advantageous addition of the guide shoe is equipped during a commissioning operation with an additional dirt deflector (not shown in the figures), which prevents penetration of larger objects into the guide slot. Such larger items may be screws, nuts or dowels, which fall down during assembly work in the shaft or it may be rough stones that break out of a wall, for example, during drilling.

The structural surface features serve primarily to clean the sliding surfaces of the guide rails 11 of dirt particles and to compensate for damage to the sliding surfaces. For example, the structural surface features may cause uneven transitions, material buckling, dandruff, such as may result in the manufacture of guide rails, burrs or grooves, or reduce their influence.

Preferably, the mounting slide inserts 13 are designed so that they can be used several times. They can be reused in other buildings, they can be used to provide new kits or they can be left in the elevator system for future work. The multiple use is economical.

As described above, the conventional sliding inserts, ie the standard sliding inserts 3, are typically made of plastic. For the Mounting slide inserts 13 is metal, preferably cast metal, used at least for the mounting track zones. In other words, the mounting slide inserts 13 are much harder and sturdier than the standard slide inserts 3. The candidate materials of Montagegleitzonen should also be harder than the sliding surfaces of the guide rails 11. The hardness of conventional guide rails is in the range of HB (Brinell hardness) = 130th to 175. The hardness of the material of the mounting track zone is at least HB = 160, such a material, for example when using GGG50, having a hardness range HB of 160 to 240. On average, therefore, the material used is harder than the guide rail.

The material of the assembly sliding insert 13 is intended to be impact-resistant, largely wear-resistant and, if possible, to be self-lubricating.

For the production of the assembly sliding inserts 13, spheroidal graphite cast iron, for example GGG50 or GGG60, has proven particularly suitable, since the mechanical properties, in particular the impact strength and hardness, and the self-lubricating properties of this material are well suited. This material is particularly advantageous. In addition, it is industrially easy to process.

Presently preferred embodiments consist of a U-shaped inherently stable element. In other words, in this case, the mounting slide insert 13 is a robust and rigid element, which is dimensioned according to the loads. Preferred is a one-piece (i.e., made of a unitary material) metal-made member in which the mounting track zones are integral with the mounting slide insert 13.

However, embodiments are also conceivable in which the mounting track zones are specially coated. As the coating, for example, TiN or a ceramic coating can be used.

In the FIGS. 3A to 3C Details of another mounting slide insert 13 are shown. The mounting slide insert 13 shown is the in Fig. 2B shown and can also be attached in a similar manner. Fig. 3A is a top view Fig. 3B a side view and Fig. 3C a sectional view taken along the line A - A. In these figures, it can be seen that this embodiment also has a substantially U-shaped configuration. The two lateral legs 18 of the U are connected by a central web 19 with each other. Also in this embodiment, three horizontal bores or milling recesses 20 are provided in the region of the mounting track zones. On the inlet and outlet side phases 22 are provided which have an angle W.

Another embodiment is the FIGS. 4A, 4B and 5A to 5C refer to. This embodiment is again similar to the other embodiments, but this time other fastening means are used, which are identified in the figures by the reference numeral 21. These may be, for example, screws which can be screwed from the side into one of the lateral legs 18 of the mounting slide insert 13. In this case, 12 holes 15.1 are provided laterally on the corresponding guide shoe. After inserting such a mounting slide insert 13 in the longitudinal groove 17 of a corresponding guide shoe 12, the mounting slide 13 can be secured against slipping out by inserting and tightening the screws 21. He is so fixed in the guide shoe 12. Of course, the mounting slide 13 can also be screwed directly using corresponding holes 15.1 in the guide shoe 12. A similar attachment may, but need not, be provided for the standard sliding inserts 3. In the embodiment according to Fig. 4A is a known standard sliding insert 3 used with retaining cams, wherein the retaining cams engage in the holes 15.1 of the guide shoe 12. The shown standard sliding insert 3 with retaining cams is made of plastic and correspondingly elastic, so that the latching can take place. The in 4A shown guide shoe 12 is provided with a base surface 16.1, to be able to be built on a lift cage or over.

What the releasable attachment of various assembly and As regards standard sliding inserts 13 and 3, respectively, the following is noted. It occur in the mounting slide inserts 13 completely different forces, since these pads 13 are so deliberately designed to interact with the guide rail 11 in order to develop a cleaning effect. That is, the attachment of the mounting slide inserts 13 should preferably be designed to be stronger / more robust than that of the standard slide inserts 3.

Preferred are those embodiments of the sliding guide device 10, in which the guide shoe 12 does not have to be dismantled in order to assemble or disassemble the slide insert 3 or 13. This has the advantage that no readjustment of the guide shoes 12 on the elevator car 14 is required because the guide shoe 12 is left in its set position and only the sliding inserts 13, 3 are exchanged.

Instead of the fastening means 15 or 21 shown but also latch-like fastening means or spring-groove connections can be used.

Sliding guide devices 10 in which the mounting slide inserts 13 can be attached to the guide shoe 12 by means of non-positive and standard sliding inserts 3 by means of positive connections are particularly well suited.

The details of the material and other features of the embodiments described above may be applied to any of the described embodiments.

In order to be able to apply the invention in practice, so-called mounting kits are supplied with an elevator installation at the time of delivery of the components, which comprises the required number of guide shoes 12, standard sliding inserts 3 and mounting slide inserts 13. In addition, the necessary fastening means 15/21 are provided for alternatively securing the standard sliding inserts 3 or the mounting slide inserts 13, wherein the standard sliding insert 3 and the mounting slide insert 13 are provided by the Fixing means 15/21 releasably in the housing of the guide shoes 12 are fastened.

Such a mounting kit can be used in the construction of a new elevator installation or in a general overhaul or modernization. In this case, the following method is preferably used for starting up an elevator installation. In a first step, the guide shoe housings 12 are fastened to the elevator car 14, in order then to insert the mounting slide inserts 13 into the guide shoe housing 12 and fasten them there using fastening means 15/21. As described above, first the mounting slide inserts 13 can be inserted into the guide shoe housing 12 before they are then attached as an assembly to the elevator car 14.

The sliding guide devices 10 with the mounting slide inserts 13 are then used during the construction or revision phase for vertical guidance of the elevator car 14 along the guide rails 11. Before a final commissioning, or in connection with the completion of the construction or revision phase, the fastening means 15/21 are then released and the mounting slide inserts 13 are removed from the guide shoe housing 12. Then, the standard slide inserts 13 are installed in the guide shoe housings 12, the slide guide assemblies 10 with standard slide inserts 13 being used during the subsequent normal operation for vertically guiding the elevator car 14 along the guide rails 11.
