Definitions
- the invention relates to a method for introducing a suspension means of an elevator in an elevator installation, as well as a support means for controlling a retraction speed of the support means when introducing the same in the elevator system. Furthermore, the invention relates to the use of such a suspension means for carrying out the method for introducing a suspension in an elevator system.
- the lift system is installed in or attached to a building.
- the building includes a shaft that extends over several floors of the building.
- the elevator system consists essentially of a cabin, which is connected via suspension means with a counterweight or with a second car. By means of a drive, usually on the support center! acting, the cabin is moved along substantially vertical guide rails in the shaft.
- the lift system is used to transport people and goods inside the building.
- the main components of the elevator installation such as the cabin, the counterweight and the drive, are generally assembled and installed at corresponding locations in the shaft or in a machine room of the elevator installation.
- the suspension means are also installed in order to then be able to move the elevator.
- a further device for braking a suspension element By means of a brake lever, a brake shoe can be pressed against a brake drum via a wire, so that the associated Tragstoffrol le can be braked or held in case of need.
- the brake lever can be fixed in a brake position and unlocked and released if necessary. However, this does not eliminate the mentioned risk. Since the support means are usually cut to length according to the required head, the support means can slip in the final phase of the suspension reel, whereby a braking of the suspension element role is no longer effective. In addition, the brake lever is actively released and must also be actively tensioned again. In case of lack of attention no braking takes place in case of doubt.
- JP2005-263476 a method for replacing an existing old suspension by a new suspension means is presented.
- the old support means and the new suspension means are guided and braked around the same axis or roller.
- the invention aims to provide a method and a corresponding device for introducing the suspension element into an elevator system, taking into account the risks identified in the prior art.
- the elevator system connects several floors of a building.
- Essential parts of the elevator system such as an elevator car, a counterweight or other installation material, are arranged in a shaft of the building.
- the shaft extends over several floors of the building.
- the several floors comprise at least the floors made accessible by the elevator system.
- the elevator car, or at least substantial parts thereof is preassembled in an upper portion of the shaft and the counterweight is preassembled in a lower portion of the shaft.
- the suspension element is wound on a suspension element roll and this is provided in a vicinity of the shaft.
- the support means can be unwound from the Tragmitteirolle and introduced into the shaft of the elevator system.
- the procedure includes the following steps.
- a suspension brake device is, in addition to Tragmitteirolle, arranged between the Tragmitteirolle and the elevator shaft.
- the suspension element is introduced into the suspension element brake device and a retraction speed of the suspension element is controlled by means of the suspension element brake device.
- the support means braking device regardless of the tragiitteirolle, can brake and hold the support means. This is achieved in particular by the fact that the suspension element brake device is arranged after the support element roller, between the latter and the elevator shaft.
- the Tragmitteirolle is often a Hoizhaspel and this reel is now spared from braking forces.
- the suspension brake device can be easily moved from installation site to installation site and can be optimized accordingly for the function "braking".
- the vicinity of the shaft in which the carrier roller is provided is selected according to a kind of the elevator and according to accessibility in the building.
- the near area is connected at least to a passage to the shaft, wherein the passage allows at least one passage of the suspension element to the shaft.
- the near zone may be a room or room area adjacent to the duct, or it may also be a distant room if, for example, the adjacent room is too narrow.
- the support roller is provided on one floor of the building, preferably on a top floor of the building. This is advantageous because floors are usually easily accessible and thus the Tragmitteirolle well delivered and can be placed near the shaft. This way, the distances to the shaft can be kept low for the subsequent installation of the suspension element.
- the carrier roll is provided in a machine room of the building.
- the machine room is located, especially in elevators with large transport heights, often directly above the shaft.
- a provision of Tragmitteirolle in the engine room or possibly in an anteroom to the machine room is advantageous because the suspension means thus usually at the highest point of the Elevator system is, and thus no further Hub energie to install the suspension means is required.
- the introduction of the suspension means comprises the following additional or supplementary steps.
- the suspension element is introduced into the suspension device by rolling a first end of the suspension element from the suspension element roll and guiding this first end through the suspension element brake device.
- the first end of the support means is passed through a top landing door, preferably pulled into the machine room or to the drive, and it is guided around a pulley of the elevator drive.
- the first end of the suspension element at a Tragstoffbefest Trentstician, preferably attached directly to its final attachment point, and the support means is lowered into the elevator shaft.
- a loop of the suspension means is weighted and guided by means of a guide roller.
- the support means is essentially pulled by a weight of the support means and a mass of the guide roller in the shaft.
- the guide roller prevents rotation of the support means loop, Further, by means of the support means brake the
- Retracting the support means, or its feed rate, are easily and safely controlled or regulated.
- the loop of the suspension element is introduced substantially to its nominal length in the shaft, preferably the loop of the suspension element is released from the guide roller and placed around a corresponding deflection roller of a counterweight.
- a second end of the support after being rolled by the support means roll, is pulled by the support means brake device. Thereafter, after being looped into corresponding deflection rollers of the elevator car, it is fastened to a cabin-side suspension element fastening point or provisionally fixed in the machine room.
- the second end of the suspension element is clamped in the upper region of the shaft or preferably in the engine room by means of a suspension-medium clamp and thus temporarily fixed.
- a suspension-medium clamp In elevator systems without Umlenkrol len on the counterweight and the cab also directly fixed the first end of the support means to a guide carriage and lowered into the shaft. By fixing a twisting or twisting of the support means is prevented.
- the support means braking device is designed such that it can apply a sufficient braking force for secure holding of the support means together with a traction resistance of the disc of the drive.
- the disk of the drive can also be provided with a sliding device, which allows a simple pulling through of the support means via the disk of the drive.
- the disc is spared and it is especially at the beginning of retraction of the support means reduces an initial force. The initial force is required until the weight of the suspension element is high enough, together with the weight of the guide roller, to pull the suspension element automatically over the drive pulley.
- a braking force of the suspension means has to be made stronger because the traction resistance of the pulley of the drive is reduced.
- the retraction speed of the suspension element is controlled by the braking force of the suspension element braking device being controlled by actuation, preferably by manual actuation, of a brake lever, which is preferably prestressed via a spring or a weight mass.
- a predetermined braking force is set automatically. This is done, for example, in that a weight- or spring-loaded brake lever presses a brake in a braking position in the absence of external force application.
- the brake lever is manually relieved and thereby reduces the braking force of the suspension element braking device.
- the braking force can be controlled manually and safety is given, since automatically eliminates the support means in the absence of manual operation.
- the design of the brake preferably provides that in the absence of manual operation or in the absence of actuating force movement of the support means is stopped.
- it is also possible to control the pull-in speed of the suspension element by detecting a pull-in speed and controlling the braking force of the suspension element brake device by means of a control device.
- the collection of the intake speed can be done via a tachometer or any speed sensor.
- the control device can regulate, for example, an electromechanical or hydraulic braking device such that the intake speed does not exceed a predetermined speed limit value.
- a support means braking device suitable for carrying out the present method preferably includes a traction disk for receiving the suspension element.
- the traction sheave is rotatably mounted in a support frame and it is designed so that the support means can at least partially wrap around the traction sheave.
- the suspension brake device includes the brake device for braking the traction sheave, wherein the pull-in speed is controllable by the brake device. This is advantageous because the suspension element is moved together with the traction sheave. The suspension is therefore spared because it does not slide on the traction sheave. Due to the fact that the braking device acts on the traction sheave, well-defined brake partners are present in their effect, and the braking is correspondingly reliable.
- This "indirect" type of braking is a direct braking, in which, for example, a pressing force acts directly on the support means, preferable. When using a direct pressing force on the support means this is pressed locally strong and exposed to a strong friction load.
- the suspension element brake device includes a suspension element insertion for receiving a suspension element extending into the suspension element brake device.
- This suspension element introduction is carried out in such a way that the suspension element is guided from a substantially horizontal feed direction to a traction groove of the traction sheave.
- the suspension means braking means a support means away guidance for the direction of a running away from the traction sheave support means strand.
- the Tragstoffweg adjustment is designed such that the support means is guided by the traction groove of the traction sheave in a Wegziigraum.
- the Wegzugraum corresponds approximately to a withdrawal direction in which the support means runs away into the shaft.
- the two support means Jckenungen are further designed such that the incoming support means Trum and the running Tragmittei-Trum each other do not hinder.
- the support means guides thus lead the two support means Trums preferably laterally past each other.
- the running-away Tragstoff-Trum runs straight away from the traction groove, while the incoming Tragstoff-Trum laterally offset on the running support means -Trum passes and is then guided in an arc to the traction groove.
- the proposed design causes the incoming tram, which is tensioned with little force, to be deflected laterally. This design allows the provision of a compact device which can gently and safely guide and brake the suspension means.
- the support 1 also includes a brake pressure roller.
- a brake pressure roller This is arranged such that the incoming Tragstoff-Trum is pressed in the vicinity of the place where the support means runs on the traction sheave on the traction sheave or the traction groove of the traction sheave.
- the maximum braking force which can be transmitted from the traction sheave to the suspension element can be increased.
- the increase is due to the fact that, based on the frictional force determined by the contact force over the following initial loop angle, the resulting pull-off force or the resulting maximum braking force of the suspension element brake device is determined.
- the pressure roller is pressed by means of a spring device to the traction sheave.
- the Andrückrol le means of a Hebeis - for example, can be rebuilt to an arm of the brake lever - or otherwise detachable from the traction disc or can be lifted. As a result, retraction of the suspension element into the suspension device can be facilitated.
- the suspension means includes a first band brake which includes an intervertebral disc connected to the traction disc and a brake band.
- the brake band wraps around the disc and it is stretched by means of the preferably preloaded brake lever.
- the brake lever is designed such that it is preferably manually operable. Band brakes are safe in operation and they are inexpensive to implement.
- the brake lever is biased by a spring or by means of a weight mass, so that in the absence of manual intervention brakes the band brake according to the bias of the spring or the weight mass.
- This is advantageous because it ensures that in the absence of manual intervention brakes the band brake and thus the support means braking device. This is an operating security of Suspension means braking device increased.
- the support means brake means further includes a second band brake which includes a further disc and which is also connected to the traction disc.
- This second band brake includes another brake band that includes the second disc.
- the further brake band preferably has a higher friction and the second band brake is through the brake lever! can be brought to effect if the previous brake band fails.
- the first band brake can be repaired without great follow-up costs.
- the brake band of the first band brake of a textile material or a plastic while the further brake band consists for example of metallic material.
- the traction sheave of the support means braking device is rotatably mounted together with the associated discs in the support frame and the other parts such as brake lever, support means guides and Andschreibrol le or guide roller are arranged in the support frame.
- the support frame thus forms a load-bearing basic structure and the entire device can be transported so easily.
- the support means braking device via the support frame on one floor of the building can be fastened.
- it can be temporarily fixed to a floor of the floor by means of dowels or it can be supported or braced to a wall, for example a wall of the elevator shaft.
- the support frame includes a transport wheel, which comes by tilting the support means brake device in contact with a floor of the floor.
- a simple displacement of the suspension element braking device is made possible.
- the Bremshebei can for example be fixed to the support frame for the purpose of transport and the support means braking device can be raised or tilted over the brake lever.
- the support means braking device can be easily changed or moved.
- the suspension may be a strap or a rope.
- a jaw brake or a disc brake can be used.
- the fitter who operates the Tragmitteibrerns noticed, also an unwinding speed of the Tragmitte! pay attention.
- he must brake the incoming suspension element quickly he can release the brake lever and he can stop the suspension element roller with a suitable brake aid. This is a slack of the support means between the support roller and Tragmitteibrerns issued counteracted. In general, however, this is not necessary, since the suspension element role usually has sufficient friction.

- a transmittable drive torque can be increased.
- This double wrap is also exemplary and is not mandatory.
- drives 10 which have no so-called counter-roller.
- the suspension brake 20 as seen in the overall view of Figure 4, consists of a traction plate 21 which is rotatably mounted in a support frame 22.

- the traction sheave 21 is, as can be seen again in FIG. 4, connected to a braking device 23.
- the traction sheave 21 can be braked as needed.
- This causes the support means 9 is moved together with the traction sheave 21, that is, that the support means on the traction sheave usually does not slip.

- a first end of the brake band 32 is fixed in the support frame 22.
- a second end of the brake band 32 is connected to a brake lever 33.
- the brake lever 33 is pivotally mounted in the support frame and a weight mass 34 biases the brake lever so that the brake band 32 of the first band brake 30 rests against the disc 31 and wraps around it.
- the first band brake generates a maximum braking force determined by the weight mass 34 and a resulting frictional force.
- This braking force is dimensioned to hold or brake the suspension means during installation. According to the experience, the maximum braking force is about 6000 N (Newton).
- the member of the installation team which operates the suspension brake, can now reduce a voltage in the brake band 32 of the first band brake 30 by lifting the weight mass or the brake lever and thus reduce the braking force.
- the suspension brake is "fail safe.” This means that releasing the brake lever sets the braking effect to a maximum value.
- the second band brake 35 is essentially not active in the described operating case.
- Another brake band 37 of the second band brake 30, see FIG. 8, is one another disc 36 of the second band brake 35 placed.

- a second end of the further brake band 37 is connected to the brake lever 33.
- the further band 37 is slightly longer than the brake band 32 of the first band brake 30, thus the second band brake does not brake in the previously described operating case, since the belt tension runs substantially over the brake band 32 of the first band brake 30.
- the further band 37 is laid loosely around the further intervertebral disc 36.
- a material of the brake band 32 of the first band brake 30 is preferably plastic, for example a rope or a belt with PU sheath.
- a material of the further brake band 37 of the second band brake 35 is preferably steel, for example a steel cord or a steel band. If necessary, a rope can wrap the intervertebral disc several times.

- Figure 9 shows an alternative embodiment of the braking device 23.
- the design of the traction sheave 21 and the ümschlingung by the support means 9 corresponds to the below
- a disc brake 40 is used in the present example.
- the disc brake 40 engages the traction sheave 21 and can brake it directly.
- the disc brake 40 presses, if necessary, as shown in Figure 1 1, brake pads
- the braking device 23 may, in another embodiment, be a mechanically actuated caliper brake.
- the caliper brake can be pressed by a spring in a braking position and then the caliper brake can be released by means of cable or lever to allow the retraction of the suspension element.
- the disc brake 40 can be controlled by a control device 19.
- an actual intake speed can be determined by the pressure roller 28 by means of a speed sensor, and the control device can set a braking force of the disk brake in order to maintain a predetermined speed value.
- the support means brake 20 may be supported instead of dowels with supports to walls or ceilings of the floor and a shape of the traction groove 25 is of course adapted to the shape of the support means. At most, several traction grooves 25 may be arranged side by side on the traction sheave. Thus, several suspension elements can be introduced into the shaft with each other. Also, of course, the embodiment of the Tragstoffweg Insert 26 shown in Figure 6 26 can be combined by means of guide roller to all other versions.
