Elevator system

The invention relates to an elevator system with a car, a counterweight connected to it via at least one cable pull and a modular elevator frame in which the car and counterweight can be moved along guides, the cable pull being attached to a fixed point at least at its end opposite the counterweight.

Such an elevator system is known from practice, in which a modular elevator frame is installed in an elevator shaft, preferably from above. The elevator frame is essentially formed by two pairs of spaced-apart guide rails as guides, which are attached to the elevator shaft at approximately right angles to each other. One pair, which is assigned to a wall of the elevator shaft, serves to guide a counterweight. The other pair, which extends centrally and transversely to the elevator shaft, serves to guide a car. Counterweights and the car are connected to one another via a cable pull, preferably made up of several cables. The cable pull is attached to an upper end of the guide rails for the counterweight and to an upper end of the guide rails for the car, each at a fixed point. A deflection pulley is arranged above the counterweight, and at least one deflection pulley is also arranged below the car to deflect the cable pull. At the upper end of a pair of guide rails there is also a drive pulley driven by a motor, around which the cable is at least partially laid to drive it.

The elevator system known from practice is relatively complex in design, since, for example, one or two pulleys for the cable pull are arranged on the elevator car and a total of two fixed points must be formed on the elevator frame. In addition, the guide rails for both the counterweight and the elevator car are arranged on both sides of these, which makes the installation of the elevator system more costly and time-consuming.

Based on the elevator system described at the beginning, the subject matter of the application is based on the task of reducing the installation and labor required to set up an elevator system while at the same time simplifying its construction.

This task is solved by forming the fixed point on the elevator car and arranging the guide assigned to the elevator car on one side of the elevator car in the elevator frame.

By designing the fixed point directly on the car, the complex mounting of one or even several pulleys on the underside of the car is no longer necessary. In addition, no additional safety devices need to be installed to prevent or at least check that the cable pull jumps out of the pulley on the car. By designing the guide for the car only on one side of the car, the installation and work required is reduced and at the same time the entire system is less expensive.

In another elevator system known from practice, a car is used without a counterweight. The elevator frame is formed by vertical pylons or the like arranged on both sides of the car. These can be assembled in a modular manner from sub-units up to the required height. A drive device with a pair of friction wheels is arranged on the underside of the car. One friction wheel rests on one side of each pylon, with another friction wheel pressing against the opposite side of the respective pylon. The other friction wheels are also rotatably mounted on the underside of the car.

The disadvantage of this previously known elevator system is that the driving ability and thus the load-bearing capacity of the elevator car is lower than that of a cable-operated elevator system. Furthermore, complex emergency braking devices and control devices are necessary, which on the one hand prevent the elevator car from falling and on the other hand enable precise access to floors. Overall, such an elevator system cannot be compared with a cable-operated elevator system.

In order to obtain a simple guide for the car, this can be formed from two guide rails along which the car is guided on one side.

Preferably, such guide rails can be formed from a T-profile with T-webs facing each other. The car is guided along the T-webs, whereby

For example, guide wheels can be pressed onto both sides of a T-bar. The T-bars usually also serve to brake the car in an emergency.

In order to be able to attach the guide rails directly to the lift frame in a simple manner, the guide rails can be detachably attached to U-brackets arranged at vertical distances in the lift frame.

A simple and sufficiently stable structure of the elevator scaffold or an elevator scaffold module is achieved, for example, by an elevator scaffold module having at least essentially vertical corner posts and cross braces connecting them. Corner posts and cross braces can be constructed in a tubular manner with a round or angular and in particular square cross-section. Corner posts and cross braces are preferably made of steel or another similarly stable material. Such materials are also sufficiently corrosion-resistant, and they can also be surface-treated to further increase corrosion resistance.

In order to be able to attach the corner posts to their lower and upper ends in a simple manner, the lift scaffold can have a lower floor element and/or an upper cover element to which the corner posts are detachably attached. This can be done, for example, by screwing or the like. The floor element and cover element also increase the inherent stability of the lift scaffold by being attached to the corner posts.

As a rule, an elevator system is arranged so that its lower end is located in a pit below the level of the lowest access to the elevator system. Furthermore, the elevator system extends above the highest access or top floor. In order to be able to assemble the elevator frame from modules, it can have at least one pit module, one floor module and one ceiling module as elevator frame modules. The pit module extends, for example, to the entry level of the lowest access. This is followed by a corresponding number of floor modules. A floor module can, for example, have a height corresponding to two, three or more floors. Furthermore, each floor module can also extend only from the entry level of one floor to the entry level of the floor above. Closing

The ceiling module is usually connected to the top floor module. Since the height of the entire system is usually known in advance when installing elevator systems, the ceiling module can also be designed as a combination of floor and ceiling modules, for example extending upwards from the entry level of the top floor.

In order to be able to attach a U-bracket to the lift frame in a simple manner, such a bracket can be arranged on a cross brace. This can be done by screwing, welding or the like.

To further simplify the installation of the elevator system, a floor module can have a floor access door directly. This is movably mounted in the elevator frame. In this context, it should be noted that the entire elevator electronics can also be delivered pre-assembled with the elevator system, so that, for example, in the area of the floor access doors, only the appropriate connections need to be made between the elevator electronics and the control buttons arranged on each floor.

To further simplify the installation of the elevator system, buffers for the counterweight and/or elevator car and/or a drive motor with traction sheave can be arranged on the floor element so that they can be transported to the installation site already pre-assembled.

In an analogous manner, pulleys for the cable pull can be mounted on a crossbeam in the elevator frame and/or on the ceiling element. The cable pull is guided via these pulleys on the one hand from the drive motor to the fixed point on the elevator car and on the other hand to the fixed point on the counterweight.

Just like the guide for the car, the guide for the counterweight can also have two guide rails, which are detachably attached in particular to an outside of a U-leg of the U-bracket. For example, two guide rails can be detachably attached to an outside of a U-leg, with their T-bars facing each other.

In order to be able to attach the lift car to the cable pull in a simple manner, the fixed point can be designed as a fixed point support that protrudes essentially vertically from a lift car wall, to which one end of the cable pull is detachably attached. The length of the fixed point support is usually determined so that the cable pull runs essentially vertically between the corresponding pulley and the attachment point on the fixed point support.

In order to be able to attach the cable pull to the counterweight in a simple manner, a mounting insert can be arranged on the top of the counterweight for detachably attaching the counterweight end of the cable pull. This can also be designed so that the cable pull runs essentially vertically between the associated deflection drum and the attachment point on the mounting insert. In addition, the deflection rollers and the corresponding attachment points on the fixed point support or mounting insert can be arranged in a plane that preferably runs vertically between a car wall and one side of the elevator frame. The traction sheave can also preferably be arranged in this plane.

In order to dampen the forces at the attachment point between the cable pull and the elevator car or counterweight, a spring element can be arranged at each end of the cable pull. This can be done by guiding the cable pull through a hole in the fixed point support or assembly insert and by arranging a spring element between the actual end of the cable pull and the fixed point support or assembly insert, which supports itself between these and the respective ends of the cable pull.

To simplify the installation of the elevator system, each guide rail can be detachably attached to U-brackets and/or to the floor element and/or cover element using fastening brackets.

In order to be able to determine the exact position of the elevator car in a simple manner, a control cable is often used that runs around the top and bottom of the elevator shaft over discs and is attached to the elevator car. Such a control cable can also be used in a simple manner in the subject of the application, whereby a control console for the rotatable mounting of a control cable drum is provided on an outer side.

a U-leg of a U-bracket or a T-beam of a guide rail, particularly in the area of the ceiling module, is detachably attached. Another control cable drum can be attached in a similar way in the pit module or on the floor element.

A simple guide for the car and counterweight can be conveniently achieved if the car and/or counterweight have guide shoes with guide slots, with a T-bar of a guide rail being at least partially inserted into each guide slot. In addition, the guide shoes can also be designed as emergency braking devices which, in the event of a fall or the like, create a frictional connection with the T-bar to brake the car and/or the counterweight by narrowing the guide slot.

A corresponding emergency braking device can also be designed at a different location and in a similar manner.

In order to be able to dispense with supporting the elevator frame in an elevator shaft as far as possible, the elevator frame and each corresponding module can be designed to be self-supporting. This means that, for example, an elevator system can be installed in elevator shafts or buildings that are otherwise not designed for corresponding loads. The self-supporting elevator frame is only attached to the side of the elevator shaft, so that essentially only forces perpendicular to the direction of travel of the elevator car are exerted on the elevator shaft surrounding the elevator frame.

The elevator system according to the invention can also be constructed completely without an elevator shaft with its self-supporting elevator frame, whereby only the pit module is arranged in a corresponding pit below the lowest access level for the elevator system. In such a case, it is advantageous for cladding the elevator frame if brackets are arranged on it for detachably fastening transparent cladding in particular to cross braces and/or corner posts. Using such transparent cladding, such as glass surfaces or the like, also results in a visually impressive elevator system, such as

it is now widely used in shopping centers, department stores, restaurants or the like.

For reasons of vibration suppression, particularly in the area of the drive device, it is also advantageous if a vibration plate can be arranged on the floor element to support the drive motor with gearbox. This dampens any vibrations that may occur and only transfers them to a small extent to the elevator frame and, if applicable, the elevator car.

A reduction in the time required to install the elevator system and a reduction in installation costs can also be achieved by having each module pre-assembled with guide rails. Pre-assembly can also include the installation of the rollers, the floor access doors, the buffers for counterweights and the elevator car, the drive motor, etc.

In the following, an advantageous embodiment of the invention is explained and described with reference to the figures attached in the drawing.

Show it:

Fig. 1 is a vertical section through an elevator system according to the invention;

Fig. 2 is a section along the line H-II of Fig. 1;

Fig. 3 shows a further section analogous to Fig. 2, in particular in the area of a floor access door, wherein the vertical section according to Fig. 1 corresponds to a section along the line l-l from Fig. 3;

Fig. 4 shows a further section analogous to Fig. 2 and 3 in the area of a pit module; Fig. 5 shows a section along the line V-V from Fig. 4; Fig. 6 shows a section along the line VI-VI from Fig. 4, and

Fig. 7 is an enlarged view of a U-bracket for holding guide rails.

Fig. 1 shows a vertical section through an elevator system 1 according to the invention. This comprises at least one pit module 19, one floor module 20 and one ceiling module 21. The modules form an elevator frame 5 which is self-supporting.

The elevator frame 5 and thus the individual modules 19, 20, 21 are made up of corner posts 15 and cross braces 16 connecting them. The corner posts 15 extend from a floor element 17 that closes the pit module 19 at the bottom to a ceiling element 18 that closes the ceiling module 21 at the top.

The floor element 17 is essentially constructed like a platform, with the corresponding platform sides being formed from supports which are closed at the top by an end plate.

The ceiling element 18 can be constructed in a similar way, with the floor element 17 and ceiling element 18 being detachably connected to the ends of the corner posts 15. The connection between corner posts and these elements is made, for example, via fixing brackets or the like, which are not shown for the sake of simplicity.

The corner posts 15 can extend over the height of the individual modules in an elevator system to be installed in an elevator shaft. The ends of the corner posts are then connected to one another in the appropriate manner. However, it is also possible to transport the corner posts pre-assembled over the entire height of the elevator system and equipped with the cross braces to an installation location for the elevator system and install them there, which is particularly advantageous for so-called glass elevators arranged on the outside of a building or inside a building.

As a rule, only the pit module 19 is arranged in a pit below the lowest access level to the elevator system. The pit module has a pit ladder 59. This can be used, for example, to access a lift mounted on the floor element 17 for maintenance purposes.

The drive motor 25 also has a gear (not shown) and drives a drive pulley 26, which drives a cable pulley 3 with sufficient driving power. In the pit module 19, buffers 23 and 24 are also arranged, see Fig. 5, for a counterweight 4 and a car 2.

In the position of the counterweight shown in Fig. 1, it is lowered to the buffer 23.

A counterweight end 38 of the cable pull 3 is attached to an upper side 36 of the counterweight 4. From this end, the cable pull extends essentially vertically upwards to adjacent to the ceiling element 18. There, the cable pull 3 is guided around a deflection pulley 28 in an essentially semicircular manner and then runs vertically downwards in the direction of the traction sheave 26. The cable pull 3 also wraps around this in an essentially semicircular manner and then the cable pull 3 runs vertically upwards to a second deflection pulley 27. This is rotatably mounted together with the other deflection pulley 28 by means of a cross member 50 in the ceiling module 21 directly below the ceiling element 18. The cable pull 3 also wraps around the deflection pulley in an essentially semicircular manner and from there is guided vertically downwards to the elevator car 2, where the cable pull 3 is detachably attached with its elevator car end 8. The attachment point between the car end 8 and the car forms a fixed point 9, see Fig. 3. An analogous fixed point is formed by attaching the counterweight end 38 to the top 36 of the counterweight 4.

U-brackets 14 are attached to cross braces 16 on one side of the lift frame 5, see also the following figures and in particular Fig. 7. Guides 6, 7 for the lift car 2 and counterweight 4 are held by means of these U-brackets 14. The guide 6 for the lift car 2 has two guide rails 10, 11 that extend from the floor element to a cross brace 16 in the ceiling module 21. The guide rails protrude upwards over this cross brace in the direction of the ceiling element 18. The guide 7 for the counterweight 4, formed from two guide rails 29, 30, see also the following figures, is also attached to the U-brackets. The guide rails 29, 30 extend parallel to and over the same height as the guide rails 10. Fastening brackets 39, 40 are used to fasten the guide rails, see

for example Fig. 7, by means of which the guide rails 10, 11 and 29, 30 are detachably attached to the various U-brackets 14.

Above the elevator car 2, a control console 41 is also detachably attached for the rotatable mounting of a control cable drum 42. The control console 41 can also be attached to a U-bracket 14, to the guide 6 or directly to a cross strut 16. The control cable 60 is guided around the control cable drum 42 and an analogous, not shown, further cable drum rotatably mounted on the floor element 17. This is attached to the elevator car 2.

Fig. 2 shows a section along the line H-II from Fig. 1. It is particularly evident that corresponding floor access doors 22, see also Fig. 1, are also arranged within the elevator frame 5. Above the elevator car 2, the cross member 50 for the rotatable mounting of the two deflection rollers 27, 28 is arranged, which extends between two opposite cross struts 16 and is fastened to it via stiffening ribs 58. The cross member 50 is formed by two spaced-apart half-beams, between which the deflection rollers 27, 28 are arranged. Below the cross member 50, a U-bracket 14 is visible, which runs with its U-web 57 parallel to a cross strut 16 and is fastened to it. The corresponding U-legs protrude perpendicularly from the U-web 57 in the direction of the elevator car 2.

In Fig. 3, a further section analogous to Fig. 2 through the elevator system according to Fig. 1 is shown, in particular in the area of the doors 22, 55. The same reference numerals as in Fig. 3 or the other figures indicate the same parts and are only mentioned in part.

In Fig. 3 it can be seen in particular that the deflection pulley 27 is arranged approximately above the traction sheave 26 and, like the deflection pulley 28, is arranged in a vertical plane with the traction sheave 26. In order to guide the cable pulley 3 essentially vertically upwards, see Fig. 1, the traction sheave 26 ends in the direction of the doors 22, 25 approximately flush with the deflection pulley 27. The cable pulley is guided around this to the fixed point 9 on the fixed point support 34, with a vertical through the fixed point 9 forming a tangent to the deflection pulley 27. The fixed point support 34 protrudes vertically from a car wall in the direction of the U-bracket 14.

Furthermore, the drive pulley 26 is arranged in such a way that it also has a common tangential plane with the other pulley 28 to guide the cable 3 vertically upwards. The cable guided around the pulley 28 is attached to the attachment point 56 on the top of the counterweight 4 as a further fixed point. It is also the case that a vertical through the attachment point 56 forms a tangent relative to the pulley 28.

The guide rails 10, 11 are attached to U-legs 32, 33 of the U-bracket 14, see also Fig. 7. The guide rails 10, 11 as well as the guide rails 29, are made of a T-profile with a T-web and T-beam.

In Fig. 3, brackets 48 are also shown in principle, which protrude from two corner posts 15 above a cross brace 16 connecting them. The bracket 48 is used, for example, to hold glass panes or similar transparent wall elements that can cover the elevator system 1 according to Fig. 1. For the sake of simplicity, further brackets on the other corner posts 15 or cross braces 16 are not shown.

In Fig. 4, a section analogous to Figs. 2 and 3 is shown approximately above the pit module 19.

In the pit module, the drive motor 25 with a gear (not shown) and buffer 24 for the elevator car are arranged on the floor element 17. Furthermore, the lower ends of the guide rails 10, 11 and 29, 30 are visible, which are detachably attached to the floor element 17 by means of fastening brackets 39, 40.

The corner posts 15 extend vertically upwards from the floor element 17, with corresponding cross struts 16 running between them to form a lifting frame with a substantially rectangular cross section.

Fig. 5 shows a section along the line V-V of Fig. 4.

A vibration plate 49 is arranged between the floor element 17 and the drive motor 25 for the vibration-damped mounting of the drive motor 25. The buffers 24 for the car 2 protrude vertically upwards from the floor element 17, with a corresponding stop for the buffers 24 arranged below the car 2.

In the illustration according to Fig. 5, only one guide rail 10 is visible, with a corresponding T-bar of this rail being arranged perpendicular to the plane of the figure according to Fig. 5.

Fig. 6 shows a section along the line VI-VI from Fig. 4. The same reference numerals again indicate the same parts and are only partially mentioned.

In particular, it can be seen in Fig. 6 that the guide rails for the counterweight, of which the guide rail 30 is shown, are also formed from a T-profile with T-web 52 and T-beam 54. The guide rail 30 is detachably attached to the base element 17 at its lower end by means of the fastening angle 40.

Fig. 7 shows an enlarged view of a U-bracket 14. This is made up of U-web 57 and U-legs 32, 33, see also Fig. 2 and 3. A fastening bracket 39 is screwed onto the U-leg 33. This is used to detachably fasten the guide rail 11 to the U-leg 33. The guide rail 11 is fastened to the fastening bracket 39 by means of its T-beam 45. The T-web 13 protrudes perpendicularly from the T-beam 45 in the direction of the opposite guide rail 10. This is made up of T-beam 44 and T-web 12 in a similar way. Furthermore, the guide rail 10 is detachably fastened to the U-leg 32 in a similar way by means of fastening bracket 39.

The fixed point support 34 is arranged between the U-legs 32, 33 and protrudes vertically from the car wall 35, see also Fig. 2 and 3, in the direction of the U-web 57. At the free end of the fixed point support 34 there is a fixed point 9 for fastening the cable pull 3. In the embodiment shown, the fixed point is formed by five fastening holes for fastening five individual cables of the cable pull 3.

Furthermore, the drive pulley 26 is shown in principle, which is visible between the U-legs 32, 33. Its center plane 61 is arranged offset relative to the mutually facing T-webs 12, 13 in the direction of the U-web 57.

For example, the controller console 41, see Fig. 1, is to be detachably attached to an outer side 43 of the U-shaped web 33 (not shown).

A fastening bracket 40 is detachably attached to an outer side 31 of the other U-leg 32 using screws. Another fastening bracket 40 is attached to the free end of the U-leg 32, for example by welding or similar. The two fastening brackets 40 are used to detachably hold the guide rail 29, 30. These are also made of a T-profile with T-bars 51, 52 and T-beams 53. The two T-bars 51, 52 are directed towards each other and the counterweight 4 is guided along them in a vertical direction.

In the embodiment shown, the counterweight 4 is composed of various shells, to the top of which a mounting insert 37 with fastening or fixed point 56 is detachably attached by screwing or the like. Below the mounting insert 37, in the shell-shaped counterweight 4, various weight inserts can be inserted according to the required weight of the counterweight.

Guide shoes 46 are also arranged on the counterweight 4, only one of which is shown on one side of the counterweight. These guide shoes 46 have a guide slot 47 into which the T-bar 51 or 52 is at least partially inserted. The guide slots 47 can be formed from a wearing part that can be replaced if necessary. Corresponding guide shoes with guide slots can also be used to guide the car along the T-bars 12, 13.
