Definitions
- the present invention relates to a guide rail for guiding a car of an elevator system and a corresponding elevator system.
- Guide rails for guiding a cabin of an elevator system are known per se from the prior art. They can serve for sliding guidance or else for roller guidance of elevator cars.
- a operated by linear drive elevator system is known.
- a roller guide is used, wherein the guide rail is a rolled steel T-profile.
- the guide rail is a rolled steel T-profile.
- a synchronous linear motor On both sides of the elevator car are located between the cabin walls and the shaft walls each have a synchronous linear motor.
- Such a linear motor has a running in the longitudinal direction of the shaft primary part, also called stationary part, on which carries stator windings.
- the primary part is attached to a stator, which in turn is attached to the shaft wall.
- the guide rail is also attached to the stator.
- the secondary part of the linear motor is formed by extending in the longitudinal direction of the cabin wall Permanentmagnetrei-. On both sides of the stator windings runs a series of permanent magnets.
- each linear motor on two rows of stator windings, each with two rows of permanent magnets. Further details on the structure and operation of the synchronous linear motors used there can be found in this document, which is expressly noted here.
- a magnetic traveling field is generated in a manner known per se in the rows of stator windings. This has the consequence that due to the series of permanent magnets, a thrust force is exerted on the elevator car in the vertical direction.
- the permanent magnet rows thus form the secondary part of the respective linear motor.
- the use of linear motors for driving elevator systems has proved to be particularly advantageous in so-called multi-car elevator systems. There several cabins drive independently of each other in a shaft.
- the cabins change the shaft to allow a circulation operation of the cabins through at least two shafts.
- the primary part of a linear drive runs together with the guide rail over the entire delivery height. Especially in heavily trafficked areas of the drive, such as holding and starting in the lobby, heat is generated at the stationary primary part of the linear drive, which can lead to an uneven temperature distribution and thus to changes in the engine parameters.
- a temperature control for the guide rail of an elevator system is known.
- a cooling tube is applied on the back of the guide rail, which is designed as a T-profile, ie between the guide rail and the shaft wall, through which a cooling medium is pumped.
- a temperature control takes over the temperature control of the cooling medium.
- the cooling tube must be bridged by means of a flexible connecting tube. Overall, the design effort of this solution is very high.
- a guide rail according to the invention is designed as a profile with at least one cavity and / or integrally formed cooling fins for cooling the guide rail.
- An elevator system according to the invention has at least one guide rail according to the invention. Frequently, two guide rails are mounted on opposite shaft walls in an elevator system, wherein a car is guided via a roller guide at its two opposite outer side walls of these guide rails.
- the production of profiles is structurally possible in a simple manner. It is particularly advantageous to integrate a plurality of cavities in the profile, wherein the cavities may have the same or different geometry. In particular, it is advantageous to extend the cavities over the entire longitudinal side of a profile.
- the cavities serve, as explained below, for heat exchange with a fluid in the cavity, which may simply be (ambient) air, but also water or a suitable refrigerant or coolant, which will be discussed further below becomes.
- the invention allows a structurally simple, reliable in continuous operation embodiment of a guide rail with improved cooling.
- no additional elements are required on the guide rail itself, which are used for cooling.
- Cavities and / or cooling fins are integrated components of the profile.
- Profiles can be rolled, drawn or pressed.
- a profile designed as an extruded profile is particularly suitable.
- the material aluminum can be used with advantage, since the material aluminum allows larger areas with less weight, as compared to steel. This brings decisive advantages in the installation and maintenance of the guide rail.
- the present invention is particularly suitable for the above-mentioned elevator systems with linear drive.
- heat builds up on the stationary part of the linear drive.
- a dissipation of this heat is of great importance.
- This can be accomplished when the stationary part of a linear motor is mounted on the guide rail according to the invention.
- a direct attachment of the stationary part of the linear drive to the guide rail according to the invention is advantageous, in particular if this attachment is formed thermally conductive.
- the resulting heat of the linear motor can then be delivered directly to the rail profile and thus effectively derived. This prevents heat buildup and resulting fluctuating engine characteristics.
- the profile is designed substantially as a U-profile, in the interior of which the stationary part of the linear motor is mounted.
- the stator windings are, for example, aluminum connection profiles which are mounted inside the rail profile. Due to the inventively existing cavities and / or cooling fins, it is more of a U-like profile than a U-profile in the strict sense, as will become clear from the embodiments.
- the cavity or cavities are formed in the longitudinal direction of the profile.
- this cavity is in operative connection with conveying means for the fluid.
- conveying means for the fluid for example, a circulation of fluid in the cavity can be provided via a pump.
- the cavity is in operative connection with adjusting means for the temperature of the fluid. Simple temperature control thus allows the temperature of the circulating fluid to be set to suitable values.
- air is suitable as fluid, such as ambient air, or also water, provided there is no danger of corrosion.
- refrigerant or coolant can be used with advantage. Coolants transport thermal energy along a temperature gradient from a higher point to a lower temperature point, while refrigerants can carry thermal energy transport against a temperature gradient.
- Natural refrigerants are, for example, ammonia, carbon dioxide, water, hydrocarbons or air. Synthetic refrigerants are based on halocarbons and are known under the common abbreviations HCFC, HFC, CFC or HFC.
- the invention further relates to an elevator system with a guide rail according to the invention, as has been explained in detail above.
- an elevator system is, in particular, a "MultiCar" elevator system mentioned in the introduction, in which several cabins can be moved independently of one another in one or more shafts.
- MultiCar elevator systems linear drives can be used with advantage, for which in turn the guide rails according to the invention are particularly suitable.
- an elevator system according to the invention may in principle also be a backpack lift.
- Figure 1 shows in cross section a guide rail for guiding a car in an elevator system according to a first embodiment
- Figure 2 shows in cross section a guide rail for guiding a car in an elevator system according to a second embodiment
- Figure 3 shows schematically a cross section through an elevator system in side view with a guide rail and a linear motor.
- FIG. 1 shows a first embodiment of a guide rail 1 in cross section perpendicular to the longitudinal direction of the guide rail 1.
- the guide rail 1 has a plurality of cavities 2a - 2f.
- the guide rail 1 is formed by an aluminum extruded profile 4. Other elements, such as for guiding or braking surfaces can be attached to the profile 4.
- the profile 4 is U-shaped.
- the stationary part 12a is mounted with its stator windings of a linear motor 12 (see FIG. 3).
- the schematic representation shows connection profiles 13 for fastening the stationary part 12a to the profile 14, wherein the connection profiles 13 advantageously also consist of aluminum.
- the direct heat-conducting connection via the connection profiles 13 allows a good heat dissipation to the profile 4 of the guide rail 1 out.
- the guide rail 1 extends over the entire travel path of a car in an elevator shaft.
- said cavities 2a-2f are formed along the entire longitudinal direction of the profile 4.
- the relevant cavity is in operative connection with corresponding conveying means, such as a pump, for the fluid.
- adjustment means for the temperature of the relevant fluid are present in order to achieve a desired setpoint temperature in the cavity (see FIG.
- FIG. 1 shows that the cavities 2 c and 2 d are filled with a gas such as ambient air, this gas being transported in particular over the entire longitudinal direction of the profile 4. It is of course also possible to introduce by means of a blower ambient air in one end of the cavity and to discharge the heated ambient air at the other end of the cavity back into the environment. Alternatively, closed cooling circuits can be used with temperature adjustment means.
- the profile 4 of the guide rail 1 according to Figure 1 also shows integrally formed cooling fins 3, which are formed in this embodiment in the inner surface of the cavity 2d. Such cooling fins 3 increase the profile surface and thus increase the effectiveness of the heat exchange to the gas located in the cavity 2d. In the same way, cooling fins 3 are formed in the interior of the cavity 2c.
- Figure 2 shows a guide rail 1, wherein like reference numerals shall designate the same elements as in Figure 1. A further explanation of these elements is therefore largely dispensed with to avoid repetition.
- the cavities 2e and 2f in the embodiment according to FIG. 2, liquids serving as refrigerants or coolants are present, which can be transported via suitable pumps in the longitudinal direction of the cavity.
- the cavities 2e and 2f are located immediately behind the stationary part 12a of the linear motor 12, so that heat arising here can be dissipated as quickly as possible.
- the cavities 2c and 2d can also be used in the embodiment of Figure 2 in the same manner as in the embodiment of Figure 1.
- the cavities 2a and 2b can also be used like the cavities 2c and 2d or 2d and 2f. Alternatively, they may serve to guide or fasten other elements that require a guide rail 1 for elevator systems.
- FIG. 3 schematically shows in cross-section a side view of an elevator system 10.
- the elevator system 10 has at least one car 11, on whose two side surfaces a secondary part 12b of a linear motor 12 is mounted.
- the guide rails are designated 1. Connected to a guide rail 1 is the stationary part 12 a of a linear motor 12.
- the elevator car 11 is accelerated in the vertical direction or decelerated for braking by a pushing force generated by the linear motors 12.
- this type of drive is particularly advantageous since elevator cable constructions can be dispensed with.
- the guide rails 1 used in the elevator system 10 according to FIG. 3 are designed as a profile with one or more cavities and / or integrally formed cooling ribs for cooling the respective guide rail 1.
- the guide rails 1 shown in Figures 1 and 2 are suitable.
- the already mentioned conveying means for the cooling fluid are denoted by 14 and here represent a pump for a cooling liquid.
- Setting means for the temperature are denoted by 15.
- the cooling fluid is passed via a conduit 16 into the cavity or cavities and exits via the conduit 17. It is advantageous to connect the conduits 16 and 17 to circulate the cooling fluid and to regulate a temperature to a predetermined value.
