Description

Method and arrangement for installing a flexible member in an elevator and installation package for the flexible member

technical field

The object of the invention is a method as set forth in the preamble of claim 1 and a method as set forth in the preamble of claim 9 for installing flexible elements of an elevator such as hoisting elements, traction elements or current and data transmission cables Arrangements in elevators, and installation packs of flexible members as set forth in the preamble of claim 14 .

Background technique

Today, the delivery of flexible members of an elevator, such as the hoisting ropes of an elevator, is realized in a separate cardboard box in which is a reel made of wood and/or metal on which the flexible member is pre-wound superior. During the installation phase, the spool is removed from the box and assembled on a separate mounting bracket acting as a tool, from which a flexible member, such as a cord, can be unwound to prevent twisting of the flexible member. Twisting can create unexpected loops which can make installation of the flexible member more difficult. When unwinding a flexible member such as a rope, the rotation of the spool must be limited to prevent uncontrolled unloading of the rope from the spool when the spool momentarily rotates faster than the rope can fit into the roping to be formed.

In solutions known in the prior art, the flexible members of the elevator, such as the ropes, are installed one at a time by means of an unloading device designed so that the free rotation of the ropes with the winding device is carried out by means of Spring force is prevented. In this case, greater friction is achieved by tensioning the spring, free unloading of the rope from the reel is prevented. Furthermore, it is known that an assistant brakes the reel, for example manually or by means of some auxiliary device.

However, there are significant disadvantages associated with the prior art. Adjustment of unloading devices as described above is difficult, so it often happens that flexible members, such as ropes, are either unloaded too quickly or not at all. In addition, simultaneous unloading of eg ropes with prior art devices is difficult. The installation of the roping thus becomes more difficult and takes a lot of time. Another problem is the need for the aforementioned mounting bracket, since there is no other use for the mounting bracket. However, many mounting brackets are necessary for installation, since elevator models are often different and often many elevators are installed simultaneously. The storage of the aforementioned mounting brackets and their transfer from the warehouse to the construction site and back to the warehouse are both costly and ecologically harmful to the environment.

Contents of the invention

The object of the present invention is to eliminate the aforementioned disadvantages and to realize an inexpensive, eco-friendly, operationally reliable and easy-to-implement arrangement for the flexible components of an elevator, such as hoisting components, traction components or current and data transmission Cable, installed in the elevator. The lifting and pulling members may be, for example, belts or ropes. Furthermore, it is an object of the present invention to achieve an eco-friendly installation package of the flexible member, which can be transported for recycling after use. The method according to the invention is characterized by what is disclosed in the characterizing part of claim 1 and the arrangement according to the invention is characterized by what is disclosed in the characterizing part of claim 9 . Furthermore, the installation package according to the invention is characterized by what is disclosed in the characterizing part of claim 14 . Other embodiments of the invention are characterized by what is disclosed in the other claims.

Some embodiments of the invention are also discussed in the descriptive section of this application. The inventive content of the application may also be defined differently than that provided in the following claims. The inventive content may also consist of several separate inventions, especially if the invention is considered in the light of wording or implicit sub-tasks or from the point of view of advantages or classes of advantages achieved. In this case, some of the features contained in the following claims may be superfluous from the point of view of separate inventive concepts. Likewise, various details provided in relation to each embodiment can also be used in other embodiments. Furthermore, it is stated that at least some of the dependent claims may be considered inventive in their own right in at least some cases.

Significant advantages are achieved by means of the invention. Thus, the self-weight of the reel and the flexible member, such as the rope, ensures that a reliable braking force is achieved. Since the unloading speed of flexible members such as ropes from the installation-related reel may be eg about 10 m/s, or even greater, it must be possible to reliably stop the reel immediately after unloading of the flexible member has ended. The ratio of rotational force to weight is generally substantially constant with respect to braking when the spool is lowered on the base of the crate.

An advantage of the solution according to the invention is also that the packaging box of the flexible member simultaneously functions as a mounting bracket when the flexible member is unwound to the processing position. There is thus no need for redundant mounting brackets, their storage position, and their transfer between the mounting position and the storage position, since the packing box itself also functions as the mounting bracket.

Another advantage is that the aforesaid flexible member remains in the box until installation in a space that is well protected from moisture and dust and does not need to be opened prior to installation. Another advantage is that the spool and all structures required to protect the spool and wind up the flexible member in a disposal location are reusable and environmentally sound. A further advantage is also that the reel according to the invention is unrolled very quickly, since a separate mounting bracket is not required.

Detailed ways

The idea of the solution according to the invention is that, for installation purposes, the flexible elements 2 of the elevator wound on reels 6, such as suspension elements, hoisting elements, traction elements or current and data transmission cables, are delivered to the installation package in an installation package. At the construction site, the installation package at least includes a packing box 1 , inside of which is a flexible member 2 wound on a reel 6 . The flexible member 2 being a suspension member, lifting member or traction member is for example a strap or a rope, which preferably has a substantially small diameter, a so-called string, for example about 3-8 mm in diameter, suitably for example about 4 mm. The packing case 1 forms storage time and transport time protection, additionally supports the reel 6 in its proper position while allowing it to rotate during installation, thereby forming a mounting bracket for installation, in which case no separate mounting bracket is required for The reel 6 is supported in its position while allowing it to rotate. In practice, during the installation phase of the elevator, a number of installation packages of this type are placed side by side on one level of the building, for example at floor level or on the floor of the elevator shaft or machine room, and the flexible member 2 on the reel 6, by Unwinding into the elevator system is pulled, for example by loading the flexible member 2, such as a suspension rope, from the reel 6 directly onto the deflection pulley of the elevator.

Figure 1 shows an oblique top side view of an installation package according to the invention, said installation package comprising at least a box 1 and inside the box a reel 6, a flexible member 2 of an elevator to be installed, for example a suspension member , a lifting member, a pulling member or a current and data transmission cable are wound on the reel. The packing box 1 comprises at least a lid, a base, a front side wall 1a, a rear side wall and a side wall 1b, and at least both the base and the side wall 1b are preferably reinforced. The two side walls 1b have an orifice 3 pointing obliquely downwards in both directions, the first end of which orifice is directed obliquely downwards towards the front wall 1a of the packing box 1, the second end of said aperture is inclined downwards point to the rear wall of the packing box 1. The reel 6 is configured to be supported by its shaft 7 in the aperture 3 of the side wall 1b. The aperture 3 functions as a mounting means and as a swivel support for supporting said spool in a manner allowing rotation within the packing box 1 . Instead of the aperture 3 , the rotation support of the rotation shaft 7 can also be completely formed on the inner surfaces of the two side walls 1 b inside the packing box 1 . In this case, the above-mentioned inner surface may have a groove in the shape of the aperture 3 , which however does not extend through the side wall 1 b to the outside of the side wall 1 b. In addition, the front wall 1a of the packaging box 1 has an aperture 5 comprising an openable lid portion 4 which is opened during installation of the flexible member 2 to enable unloading of the flexible member 2 from the reel 6 to the process. Location.

The entire installation package is made of environmentally friendly recyclable materials, which can be shipped for re-use after installation of the flexible member 2 . The packaging box 1 , which is substantially rectangular prism-shaped, is a material composed of vegetable fibres, preferably wood fibres, eg cardboard, eg corrugated cardboard, folded on top of each other in the required number of layers. Correspondingly, the body of the reel 6 is made of vegetable fibers, preferably of wood fibers pressed together or of another kind of cardboard, or also of wood. In addition, the shaft 7 of the reel 6 is also made of vegetable fibers, preferably for example wood fibers pressed together, or the shaft can also be a turned shaft of wood.

Figures 2 and 3 show cutaway side views of a mounting bag according to the invention. In the situation according to FIG. 2 , the reel 6 is in its first position within the packaging box 1 separated from the inner base 8 of the packaging box. In this case, the spool 6 is supported by its shaft 7 in the first end of the aperture 3 in a manner that allows substantially free rotation. This position allows the reel 6 to rotate substantially freely. However, if the rotation of the spool 6 requires braking, the spool 6 can be arranged in its second position shown in FIG. 3 so that the shaft 7 of the spool 6 is displaced to a second end of the aperture 3 which is more The first end is low. In this case, the outer rim of the spool 6 touches the inner base 8 of the package 1 , in which case the friction generated by the abrasive contact properly brakes the rotation of the spool 6 .

FIG. 4 shows an installation package according to the invention as seen from the front of the packing box 1 . From Figure 4, it is clear how the ends of the axis of rotation 7 of the reel 6 extend in both directions from the side wall 1b of the packing box 1 while resting on the orifice 3 in the side wall 1b And it is a stationary support and a rotating support of the rotating shaft 7 .

Figure 5 shows in more detail the side wall 1b of the packing box 1 of the installation pack according to the invention as seen from the side. The opening 3 in the side wall 1 b has two branches, both pointing obliquely downwards, wherein the opening supports the shaft 7 of the reel 6 . A first end 3a of the aperture 3 is directed obliquely downwards towards the front wall 1a of the packing box 1 and a second end 3b of the aperture 3 is directed obliquely downwards towards the rear wall of the packing box 1 at substantially the same angle. The first end 3a of the aperture 3 is shorter than the second end 3b such that the first end 3a of the aperture 3 is farther from the inner base 8 of the packing box 1 than the second end 3b of the aperture 3 . The distance of the aperture 3 from the inner base 8 is dimensioned relative to the diameter of the spool 6 so that when the shaft 7 of the spool 6 is at the first end 3a of the aperture 3, the outer edge of the spool 6 is in contact with the packaging box. 1 of the inner base 8 and accordingly when the shaft 7 of the reel 6 is at the second end 3b of the aperture 3, the outer edge of the reel 6 simultaneously rests on the inner base 8 of the packing box 1 for achieving 6 Braking action when rotating.

In the method and arrangement according to the invention, one or more packaging boxes 1 with reels 6 are arranged side by side at a building level during the installation phase of the flexible member 2, for example at floor level, in an elevator shaft on the floor of the machine room or on the floor of the machine room and are to be installed in the same environment, by rotating said flexible member 2 from the box 1 in its proper position to serve as a winding stand The reel 6 is unloaded, for example by pulling the flexible member 2 out of the crate 1 with the elevator's own machinery or by another suitable mechanism, while simultaneously being loaded into said elevator system.

Before the flexible member 2 is unloaded from the packing box 1, the rotating shaft 7 of the reel 6 is arranged in the first end 3a of the aperture 3, after which the reel 6 is placed in the aperture 3 by pulling the flexible member 2 out of the reel 6. Rotate in the first end 3a. The rotation of the spool 6 is controlled, if desired, by displacing the axis of rotation 7 of the spool 6 to the second end 3b of the aperture 3 and by rotating the outer edge 6a of the spool 6 against the inner base 8 of the box 1. brake.

The spool 6 is supported on the packaging box 1 for rotation within the packaging box 1 substantially throughout the time the flexible member 2 is loaded. When the reel 6 is rotating in the first end 3a of the aperture 3, the reel 6 is supported via its shaft 7 on the aperture 3 and at the same time on the side wall 1b of the packing box 1, and when the reel 6 is rotating in the aperture. While rotating in the second end 3b of the mouth 3, the spool 6 is mainly supported on the inner base 8 of the packing box 1, while receiving its guidance from the mouth 3. After loading the flexible member 2 and when said reel 6 is empty, the crates 1 are shipped with their reel 6 and shaft 7 for recycling.

It should also be noted that the different solutions shown above may be inventive features together with one or more other features of the invention.

It is obvious to a person skilled in the art that the invention is not limited to the examples described above, but that it may vary within the scope of the claims presented below. Thus, for example, the shape, structure and operation of the crates and reels and rotating shafts may also differ from those provided above.

It will also be apparent to those skilled in the art that the spool could be braked, if desired, other than by letting the outer rim of the spool grind against the inner base of the crate. The side walls of the crate may for example have holes at suitable locations into which cardboard or wooden pins may be placed and against which the reel may be made to rotate by a suitable offset.
