Definitions

  • the invention relates to a lift according to the preamble of claim 1.
  • the elevators used in buildings often comprise a car and a counterweight, which are connected to each other via a cable connection, and a drive.
  • the cable connection is designed according to the needs.
  • the cable or steel cable is preferably guided over at least one deflection roller which is fastened above the uppermost position of the cabin. From the drive, the rope is set in motion, whereby the movements of the counterweight and the car take place in opposite directions.
  • a control and a drive motor allow the desired movements of the cabin.
  • the EP 1 305 249 B1 describes a traction sheave drive machine, which is arranged together with the operating electronics to the cabin.
  • the described embodiments comprise a synchronous motor with planetary gear and traction sheave according to the DE 197 39 899 A1 , Such drive motors generate unwanted noise in the cab.
  • the rope diameter must be adapted to the diameter of the driving element.
  • a steel rope with a small diameter must be used.
  • two or more steel cables are arranged in parallel.
  • the EP 1 106 559 B1 describes a drive in the counterweight, in which the motor frictionally acts on a stationary guide profile via a drive roller. Due to the small diameter of the drive roller, the drive does not require a particularly large area of the elevator shaft. However, it has been shown that frictional force transmission from the drive roller to the guide profile is already problematic due to the friction loss. In addition, the drive roller receives an unbalance and thus an undesirable uneven running due to the long downtime and the large contact force. From the drive roller unwanted noise is transmitted to the guides of the counterweight and thus on the shaft. The engine is powered by a battery at the counterweight.
  • the counterweight In order to charge the battery, the counterweight is moved to a loading position in which a transformer part arranged on the shaft and a transformer part arranged on the counterweight cooperate, thereby enabling power transmission. A rectifier is used to charge the battery.
  • the repeated positioning of the counterweight in the loading position restricts the use of the elevator at any time immediately.
  • US 5 086 881 describes an elevator whose counterweight is driven by a linear motor.
  • the linear motor consists of a fixed, long part which extends along the direction of movement of the counterweight and a short part movable along the direction of movement of the counterweight, which is connected to the counterweight and cooperates with the long part.
  • the fixed, long part of the linear motor extends along the entire length of the shaft. The connection between the car and the counterweight runs over two independent ropes, which tend to tilt the cab and / or the moving part of the linear motor at an unbalanced load.
  • US Pat. No. 7,404,468 B2 discloses an elevator car driven directly by a drive in which the cabin is moved by rotation of a spindle.
  • the drive device consists of a long part extending along the direction of movement of the car, namely a spindle and a short part cooperating with the spindle, namely a spindle nut.
  • the spindle nut is on the one hand connected to the cabin and on the other hand so arranged on the spindle, that a rotation of the spindle about its axis leads to a movement of the spindle nut along the spindle axis.
  • the spindle and the spindle nut thus act operationally or efficiently together.
  • the spindle nut is rotatable in the illustrated embodiment with a fixed spindle, which also leads to a movement of the spindle nut along the spindle axis.
  • the spindle For such a drive of the cabin with a rotatable spindle, the spindle must extend over the entire shaft height, which is associated with a large material and installation costs for the spindle. Higher cabin speeds are difficult to achieve.
  • the invention is now based on the general object to find an elevator which avoids the disadvantages of the prior art.
  • An elevator for a shaft comprises a car and a counterweight, wherein the car and the counterweight are connected to one another by a cable connection, so that the car can be moved over a shaft length.
  • the cable connection runs over at least one deflection roller and the counterweight is driven by a drive device with a long drive part extending along a direction of movement of the counterweight and a short drive part cooperating with the long drive part, wherein the position of the short drive part is adjustable on the long drive part and one of the both parts are arranged on the counterweight and the other stationary on the shaft.
  • the relative movement between the short drive part and the long drive part leads to a movement of the counterweight in the elevator shaft.
  • the movement of the counterweight achieves a desired cabin movement.
  • the cable connection comprises a cable which is fixed at a first end or fixed to the counterweight and at a second end or arranged on the cabin.
  • the rope For holding the counterweight, the rope comprises at least two downwardly-facing counterweight cable sections and for holding the cabin, the cable comprises at least one cabin cable section. Between adjacent cable sections, the rope is guided above each stationary over pulleys and at the bottom over pulleys on the counterweight or on the cabin.
  • the number of counterweight cable sections is greater than the number of cabin cable sections and the long drive section extends substantially over a maximum of two thirds of the shaft length or shaft height. Because the number of counterweight cable sections is greater than the number of cabin cable sections, can with one movement the counterweight over a portion of the shaft length, the cab be moved over the entire length of the shaft.
  • the stationary deflection rollers are arranged at the upper shaft end above the car or above the counterweight.
  • the cabin and the counterweight move in opposite directions. Because the number of counterweight cable sections is greater than the number of cabin cable sections, a certain movement length of the counterweight corresponds to a greater movement length of the car. For example, if three counterweight cable sections and two cabin cable sections are provided, then a movement of the car over the entire shaft height is associated with a movement of the counterweight over only 2/3 of the shaft height. Correspondingly, a long drive part, which extends substantially at most over 2/3 of the shaft length or shaft height, is sufficient.
  • the counterweight is held in a pulley cable arrangement with two loops and the cabin in a loop of rope.
  • a movement of the cabin over the entire shaft height is associated with a movement of the counterweight over only half the shaft height. Accordingly, a long drive part which extends substantially at most over half the shaft length or shaft height is sufficient.
  • the drive motor can be arranged on the shaft side or on the counterweight, with each easily a space-saving and service-friendly arrangement can be found.
  • the new solution provides a smooth and energy-efficient elevator that increases the ride comfort of passengers and brings economic benefits.
  • the long drive part is stationarily arranged on the shaft and the short drive part on the counterweight.
  • the long drive part on the counterweight and the short drive part is arranged stationarily on the shaft.
  • Embodiments in which the long drive part is a threaded spindle and the short drive part is a spindle nut arranged on the threaded spindle are particularly preferred.
  • the drive device then comprises a drive motor which makes the threaded spindle or the spindle nut rotatable about the spindle axis. The relative position of the spindle nut shifts on the threaded spindle. Because the spindle nut or optionally the threaded spindle on the counterweight and correspondingly the threaded spindle or the spindle nut is arranged stationary, the relative movement of the spindle nut and threaded spindle leads to a movement of the counterweight in the elevator shaft.
  • a fixed arrangement of the threaded spindle or spindle nut means that the respective stationary element remains in the same position in the direction of the shaft length or shaft height.
  • a stationary spindle can be rotatably mounted about its longitudinal axis or driven about this axis.
  • a stationary spindle nut can be rotatably mounted about its threaded axis or be driven about this axis.
  • this can rotate a stationary threaded spindle or a stationary spindle nut about the spindle axis, so that the attached to the counterweight spindle nut or threaded spindle moves with the counterweight in the elevator shaft.
  • the latter can rotate a threaded spindle or spindle nut rotatably mounted on the counterweight about the spindle axis so that the rotating part moves in the elevator shaft in engagement with a stationary spindle nut or threaded spindle fastened to the elevator shaft and this together with the counterweight ,
  • the long drive part is a rack and the short drive part is a gear meshing with the rack, which is rotatable by a drive motor. This shifts the relative position of the gear on the rack. Because the gear or optionally the rack on the counterweight and correspondingly the rack or the gear is arranged stationary, the relative movement of the gear and rack leads to a movement of the counterweight in the elevator shaft. Over the rope, the movement of the counterweight leads to the cabin movement. In the solutions with racks of the drive motor is arranged in each case at the gear, so either on the counterweight or on the elevator shaft.
  • the long drive part is a permanent magnet sequence and the short drive part is an electromagnetic arrangement of a linear motor interacting with the permanent magnet sequence.
  • the permanent magnet sequence is arranged stationarily on the shaft and the electromagnet arrangement on the counterweight. If necessary, they are also arranged in the opposite direction.
  • Such a linear motor can drive a movement of the counterweight in the elevator shaft. Over the rope, the movement of the counterweight leads to the cabin movement.
  • Fig. 1 shows an elevator shaft 1 with access doors 2 and an elevator 3.
  • the elevator 3 comprises a car 4 with car walls 4a and at least one car door 4b on a front side.
  • two first guide profiles 5 are arranged on the elevator shaft 1.
  • guide shoes 6 of the car 4 are guided.
  • a counterweight 7 is movably guided on second guide profiles 8 in the direction of the chute.
  • the counterweight 7 reduces the driving force necessary for the cabin movement and is driven by a drive device 9.
  • the drive device 9 comprises a long drive part 10 extending along a movement direction of the counterweight 7 and a short drive part 11 cooperating with the long drive part 10, the position of the short drive part 11 being adjustable on the long drive part 10 and one of the two parts on the counterweight 7 as well the other is fixed to the shaft.
  • the long drive member 11 is a parallel to the second guide profiles arranged threaded spindle which is displaceable by a stationary, or on the elevator shaft 1 arranged drive motor 12 about its axis in rotation.
  • the short drive part 11 is a spindle nut, which is arranged on the counterweight 7 and engages in the threaded spindle, so that it is movable by the rotating threaded spindle together with the counterweight.
  • a cable 13 is fastened with both ends to the upper end of the elevator shaft 1, wherein only one of the two fastenings - namely on the counterweight 7 - is shown in the figure ,
  • the rope 13 forms the counterweight 7 two loops, in which the cable 13 is guided around two counterweight deflection rollers 14 a on the counterweight 7 and therebetween and thereafter to a stationary upper guide roller 14 b.
  • the rope is in a loop to the cabin and then to the second attachment at the top End of the elevator shaft 1 out.
  • the cable 13 is guided around two cabin deflection rollers 14c.
  • the two loops of the counterweight 7 form in cooperation with the one loop of the car 4 a pulley arrangement, so that the counterweight 7 moves only over half of the shaft height, while the car moves over the entire shaft height.
  • the threaded spindle (long drive part 10) extends over half the shaft height, so that at an outgoing from the lower shaft end threaded spindle (long drive part 10) is its upper end 10a in the range half the shaft height.
  • FIGS. 3 to 6 show embodiments with different variants of cable guides.
  • the cable 13 In the 3 and 6 is the first end of the rope fixed and in the 4 and 5 it is attached to the counterweight G.
  • the second end of the rope is in the 4 and 6 stationary and in the FIGS. 3 and 5 attached to the cabin K.
  • the cable 13 For holding the counterweight G, the cable 13 always comprises at least two downwardly leading counterweight cable sections G1, G2, G3, G4, wherein in the Fig. 3 two, in the 4 and 5 three and in the Fig. 6 four counterweight rope sections are used.
  • the cable 13 comprises at least one cabin cable section K1, K2, wherein the FIGS. 3 and 5 one and the 4 and 6 show two cabin rope sections. Between adjacent cable sections, the cable 13 is guided above each stationary over pulleys 14 b.
  • counterweight pulleys 14 a and 14 are arranged on the cabin K cab pulleys.
  • the number of counterweight cable sections G1, G2, G3, G4 is always greater than the number of cabin cable sections K1, K2. Therefore, with a movement of the counterweight G over part of the shaft length, the car K can be moved over the entire length of the shaft.
  • the fraction of the number of cabin cable sections divided by the number of counterweight cable sections corresponds to the proportion of the counterweight path in the cabin. In the arrangement according to Fig. 4 If this fraction is 2/3, then the counterweight must be able to be moved over 2/3 of the maximum cabin distance.
  • the long drive part must therefore extend substantially over two thirds of the shaft length or shaft height. In the arrangements according to the 3 and 6 If this fraction is 1/2 (or 2/4), so that the counterweight must move over 1/2 of the maximum cabin distance.
  • the long drive part must thus extend substantially only over half of the shaft height. In the arrangement according to Fig. 5 this fraction is 1/3, so that the counterweight over 1/3 of the maximum cabin distance.
  • the long drive part therefore essentially only has to extend over one third of the shaft height.
  • the elevator shaft or the shaft height is displayed with the upper and lower shaft ends 15.
  • the car positions are shown for the cabin pulleys 14c, KP1 being the one currently displayed, KPo being the top and KPu the lowest cab.
  • a spindle nut is arranged as a short drive part 11, which cooperates with the threaded spindle (long drive part 10) rotatable by the drive motor 12.
  • the spindle nut or the counterweight can be moved from the current position GP1 to the top or bottom position GPo, GPu.
  • the long drive part 10 can be arranged at different positions in the elevator shaft, for example in the lower, upper or middle area.
  • the drive motor 12 may be disposed at the lower or upper end of the long drive part 10.
  • the counterweight and the cable assembly are chosen so that the maximum cabin movement counterweight G is to be moved over the area with the long drive member 10.
  • a solution is shown in which the threaded spindle or the long drive part 10 is attached to the counterweight G and the threaded spindle or the short drive part of the stationary drive motor 12 is set in rotation.
  • the threaded spindle In order to move the counterweight in the uppermost position, the threaded spindle is moved upwards by the spindle nut by the length Lo. In order to move the counterweight to the lowest position, the threaded spindle is moved upwards by the spindle nut by the length Lu. It goes without saying that the threaded spindle so on the counterweight it must be arranged that the counterweight G can be moved over the area that is necessary for the maximum cabin movement.
