Definitions

• the invention relates to an elevator with a cable-driven cabin, to which vertical guide rails are assigned.
• An elevator is usually installed inside a vertical shaft that is part of or rigidly connected to a building structure so that it forms a unit with it.
• the shaft is made of concrete, metal, glass or a combination of these materials and is a heavy and expensive component.
• the shaft is imperative to protect the cables connected to the cabin from the weather, in particular from moisture, since moisture the friction between the ropes and the associated traction sheave is negatively affected.
• the object is achieved in that the ropes are arranged in a housing on both sides of the cabin and acted upon by a common traction sheave.
• the ropes on each side of the cabin are expediently coupled to the cabin on the one hand and to a counterweight on the other. This is accompanied by an even load on the ropes and a reduction in the power of the drive of the traction sheave, since the forces acting on each other cancel each other out.
• the counterweight and the cabin are located on opposite sides of a vertical support holding the guide rail.
• the vertical beams arranged on both sides of the car represent the only essential static components of the elevator. They can be arranged, for example, in the area of the front of the car provided with a door and connected to a building.
• a free installation of the elevator is possible, in which the vertical beams, for example by means of tensioning rope. len are held. This type of installation of the vertical supports and thus of the elevator is possible, for example, when used in a tent construction or at a trade fair stand or the like, relatively unstable components.
• each vertical support is preferably designed as a double-T support and arranged in the housing.
• the vertical beams can, for example, be fastened on at least one foundation in such a way that the entire elevator can be set up free-standing, that is to say without further supports.
• the vertical supports are preferably provided at their upper ends with a bracket for mounting the traction sheave and a plurality of deflection sheaves for the ropes, the bracket extending like a bridge between the two vertical supports.
• the deflection sheaves are of course arranged in relation to the traction sheave in such a way that the ropes encompass them at angles of wrap that correspond to the relevant technical rules.
• a motor driving the traction sheave is expediently fastened to the console with the interposition of a transmission. If the motor is designed accordingly, the gearbox can be dispensed with, ie the drive can be “gearless”.
• the console carries control electronics. Of course, the control electronics, the motor and the gearbox below the are also possible Arrange the cabin stationary and guide the ropes to the cabin using appropriate pulleys.
• the vertical supports are preferably fixed in a shaft pit with the end opposite the console.
• the shaft pit for example concreted, on the one hand ensures that the vertical girders are securely fastened and on the other hand provides free space below the cabin in its lowest end position.
• the vertical beams are connected to one another by means of a plurality of cross beams spaced apart from one another.
• each vertical support is preferably aligned parallel to the cabin and carries the guide rail on the side facing the cabin.
• the guide rail is thus arranged within the U-shaped free space spanned by the flanges and the web of the vertical support.
• the flanges on the side of the vertical support opposite the guide rail have guide means for supporting the counterweight in the corresponding U-shaped recess in the vertical support. Due to the arrangement of the counterweight and the guide rail to the web of the vertical support, the vertical support is subjected to a compressive stress.
• the guiding means are expediently designed as angle profiles fastened opposite to the flanges, on which are attached to the counterweight.
• the tip of the angle profile points in the direction of the counterweight and the guide rollers are aligned such that their running surfaces roll over the entire surface of the legs of the angle profile.
• the cross-sectionally T-shaped guide rail is preferably fixed to the web of the vertical support with the interposition of a holder profile in such a way that its foot runs parallel to the web of the vertical support and its web, which is guided between rollers on the cabin side, points in the direction of the cabin. Since both guide rails and rollers are located on both sides of the cabin, the cabin is mounted reliably, the mounting only permitting the cabin to move up and down.
• the rollers are mounted on a U-profile which is connected to a frame of the cabin via an angle bracket.
• a beam made of a U or flat profile can also be used, for example, and the U profile can be replaced by an angle profile, for example.
• the frame is expediently composed of profiles which are U-shaped in cross section, the legs extending over the height of the cabin pointing in the direction of the respectively assigned vertical support and one leg of the profile is connected to one leg of the angle profile, the other leg of which holds the U-profile. Because of this relatively stiff construction, the rollers are always in contact with the associated guide rail.
• the cabin is preferably assigned a protective housing extending over its height on both sides, which covers the corresponding profiles of the frame and the one passage for the corresponding profile has associated leg of the angle leg, which projects through a slot of the housing accommodating the associated vertical support.
• the openings namely the passage of the protective housing and the slot of the housing through which moisture could penetrate, are thus kept relatively small, nevertheless ensuring reliable storage of the cabin between the vertical supports.
• the passage is expediently formed between two protrusions of the protective housing, which protrude through the slot of the housing. The housing is thus nested with the protective housing in the area of the openings and the ingress of water is prevented.
• the housing carries on both sides of the slot V-shaped sealing lips that rest on the projections of the protective housing. This prevents rain or snow, which strikes the protective housing or the housing, from getting into the interior of the same and there impairing the ropes or the guides.
• a trigger of a safety device is assigned to the one guide rail of electrical cables and the other guide rail within the respective housing.
• the electrical cables preferably protrude through the slot in the housing and the passage of the protective housing into the interior of the cabin.
• the electrical cables which serve on the one hand to supply energy to consumers within the cabin and on the other hand to control the elevator, and the trigger of the safety device, which acts on the two guide rails, as known from the prior art, are housed weather-protected inside the housing.
• the traction sheave and the deflection sheaves are preferably covered by a hood.
• a motor, gearbox and control devices under this hood, which are thus protected from the weather, so that the elevator is suitable for outdoor installation.
• the hood can be pivoted for maintenance work or have a flap or door.
• a wire rope is fastened on both sides of the cabin on the one hand to the respective counterweight and on the other hand to the cabin, the wire rope running below the associated vertical support and holding a deflection roller with a tensioning weight.
• a hoist is attached to the wire rope to either pull the cabin up or down when the drive brake is released. Since the cabin is both on an ascent and a descent downward trap can get caught, different procedures are required to release the safety gear. The cabin must be moved upwards after emergency braking during a downward journey.
• one end of a hoist is fastened to the section of the wire rope assigned to the counterweight, the other end of which, in contrast, is fixed further down in a shaft pit in which the deflection roller with the tensioning weight is located.
• the counterweight is moved downwards and consequently the cabin is moved upwards, so that the safety gear comes out of operative engagement.
• one end of the hoist is fastened to the section of the wire rope assigned to the counterweight, the other end of which, in contrast, is fixed further above.
• the tensioning weight is fixed, for example, by fixing the deflection roller. Then, after releasing the drive brake of the elevator, the car is pulled down to disengage the safety device.
• the cabin and / or the area covered by the hood are expediently connected to a heating and / or air conditioning system for temperature control.
• a balcony is advantageously provided on the level of a floor of each floor between a ner exterior door of the elevator and a building.
• the balconies also serve as roofing for the balconies underneath, although a roof can of course be provided above the balcony for the top floor. It is also possible to dimension the balconies in such a way that they can be used as a seat.
• a plurality of balconies are preferably connected to one another by means of a scaffold.
• the scaffold is expediently free-standing or attached to the building and / or to the vertical supports.
• the balconies are arranged on the vertical beams.
