Definitions

  • the invention relates to a lift according to the preamble of patent claim 1.
  • both the elevator car and the counterweight are each assigned a pulley.
  • the respective ends of the drive cable driven by a drive pulley of a drive unit are fastened at different attachment points in an upper region of the shaft.
  • a disadvantage of the known elevator is that the traction sheave must be designed relatively bulky and a larger support cable length must be provided.
  • WO 03/099696 A1 From the WO 03/099696 A1 is an elevator with a guided in a shaft elevator car and with a counterweight known, wherein a plurality of pulleys are arranged such that a 2: 1 suspension is formed. For a 1: 1 suspension, the known elevator is not suitable.
  • An elevator with an elevator car guided in a shaft and with a counterweight is known in which a drive unit is arranged in vertical projection of the elevator car beside it.
  • a drive unit is arranged in vertical projection of the elevator car beside it.
  • several deflection rollers are provided, wherein two deflection rollers are arranged on opposite sides of the shaft axially parallel to each other.
  • a disadvantage of the known elevator is that a Dividing the coming of the counterweight support rope is required in two sub-strands, the ends of which are fixed on opposite sides of the elevator car.
  • a disadvantage of the known elevator is the relatively large installation effort.
  • the object of the present invention is to develop an elevator with an elevator car guided in a shaft and with a counterweight in such a way that a space-saving drive unit with a shorter support cable length and a reduction of operating noise is provided.
  • the invention has the features of claim 1.
  • a fixed spatial arrangement between a traction sheave and a guide roller wherein a support cable wraps around the traction sheave and / or the guide roller at an angle of at least 180 °. Due to the relatively high degree of wrap of the support cable, in particular on the traction sheave, the same can be constructed with a reduced diameter, so that the drive unit can be arranged together with the also compact guide roller space-saving in the upper region of the shaft. An additional provision of pulleys on the counterweight or on the elevator car is not required. It follows according to the invention thus a compact and self-sufficient drive unit, which can be advantageously installed in existing buildings without a shaft.
  • a first end of the support cable is connected to the counterweight, so that the support cable forms a fixed point on the counterweight. Furthermore, a second end of the support cable is connected to an upper side of the elevator car, so that the support cable forms a second fixed point with the elevator car.
  • this 1: 1 suspension results in a simplified assembly of the elevator, wherein the drive unit contains all the essential drive components and the ends of the support cable must be attached only to the counterweight or the elevator car. The fact that the drive unit runs laterally to a vertical projection of the cabin, a roof of the cabin can be used without restriction of the shelter for maintenance purposes.
  • An elevator 1 consists essentially of an elevator car 2, a counterweight 3, a drive unit 4 and a support cable 5, via which the elevator car 2 is coupled via the drive unit 4 to the counterweight 3.
  • the elevator car 2 is guided in a vertical shaft 6 of a not darg Whytunasis.
  • the elevator car 2 is guided in a vertical shaft 6 of a not darg Whyen building via guides 7 and has in known manner space for receiving persons or objects.
  • the drive unit 4 of the elevator 1 in an upper end portion 8 of the shaft 6 fixed to a cross member 12 of the shaft 6 shown schematically or attached to a guide rail of the elevator or counterweight.
  • the drive unit 4 essentially has an electric motor 9, a traction sheave 10 coupled to the output shaft of the electric motor 9 and a deflection roller 11.
  • the traction sheave 10 and the guide roller 11 are arranged parallel to the axis substantially in the horizontal direction next to each other. They extend itself in a longitudinal center plane 13 of the shaft 6.
  • the electric motor 9 is arranged next to it in a region close to the longitudinal center plane 13.
  • the traction sheave 10 is wrapped by more than 180 ° of the support cable 5.
  • the Umschlingungsgrad is about 270 °, since a coming from below vertical support cable section 16 and a second end 14 of the support cable 5 attached to an upper side 15 of the elevator car 2 supporting rope 5 is placed around the traction sheave 10 and rests on the deflection roller 11 at an intersection , 180 °, wherein a counterweight-carrying cable section 17 of the supporting cable 5 on a side facing away from the traction sheave 10 of the guide roller 11 extends in a vertical direction downwards, wherein a first end of the 18th of the counterweight support cable section 17 is attached to the counterweight 3 and thus forms a fixed point.
  • the elevator car carrying cable section 16 and the counterweight carrying cable section 17 run approximately parallel to one another, wherein the free ends of the sections 16, 17 are firmly connected to the counterweight 3 and the elevator car 2, respectively.
  • On a side facing away from the ends 14, 18 of the supporting cable sections 16, 17 is a connection to the drive unit 4 integrated traction sheave 10 and pulley 11.
  • the traction sheave 10 and the guide roller 11 rotate in opposite directions about the respective axes of rotation extending perpendicular to the support cable sections 16, 17 and perpendicular to the longitudinal axis of the shaft 6.
  • the support cable 5 In a region between the traction sheave 10 and the guide roller 11, the support cable 5 intersects or intersect two Umschlingungsabête 19, 19 'of the support cable 5 and intersect in a projection plane perpendicular to the axes of rotation of Traction sheave 10 and der Umlenkrolle 11 runs.
  • the elevator car carrying cable section 16 thus extends in a vertical plane which is arranged between the traction sheave 10 and the deflection roller 11.
  • an elevator 1 ' is provided, which has a higher degree of wrap of a traction sheave 10' and a deflection roller 11 'than the elevator 1 according to the first embodiment.
  • Identical components or functions of the embodiments are provided with the same reference numerals.
  • a supporting cable 5 ' wraps around the traction sheave 10' and the deflecting roller 11 'corresponding to an angle of 540 °.
  • FIG. 7 and FIG. 8 It can be seen more clearly that a supporting cable section 16 facing the end of the cabin 2 extends first under contact with a lateral surface 33 of the deflecting roller 11 'in the direction of the traction sheave 10'.
  • the traction sheave 10 ' is looped through 180 °, so that a lower strand 30 is again guided back to the deflection roller 11'.
  • an upper run 31 is again guided to the traction sheave 10'.
  • At the traction sheave 10 ' is a wrap of 90 °, so that the support cable 5' merges into a vertical support cable section 17, which leads to a weight 3 facing the end 18 of the support cable 5 '.
  • the support cable 5 ' is guided with the upper strand 31 or lower strand 30 in the circumferential surface 33 of the traction sheave 10' and the guide roller 11 'recessed grooves.
  • two parallel grooves of the discs 10 ', 11' are used.
  • the Traction sheave 10 'and guide roller 11' also have a plurality of grooves, so that the Umschlingungsgrad is further increased.
  • the driving ability is further increased.
  • the number of supporting cables 5 ' can be reduced to four, wherein for safety reasons always at least three supporting cables 5' are prescribed.
  • the diameter of the support cables 5 'and the traction sheave 10' can be made smaller - the diameter of the traction sheave 10 'may be less than 200 mm, for example - so that less torque or driving force is necessary.
  • the drive unit 4 for the elevator 1 'can thus be made more compact and smaller.
  • An electric motor 9 of the drive unit 4 can be arranged in the region of the traction sheave 10 'at the edge and thus not in vertical projection to the car 2 above it. As a result, the risk of crushing during maintenance of the elevator can be reduced.
  • the motor 9 can also be arranged in an upright position, that is to say by 90 °, pivoted to the position according to the embodiment.
  • the ends 14 and / or 18 of the supporting cable 5 'on the car 2 or on the counterweight 3 can be deflected by means of a roller and coupled to a permanently connected to a wall of the shaft 6 role.
  • the speed of the elevator car 2 can be doubled with the same force. It is understood that the at the cabin 2 or at the weight 3 deflected portions of the support cable 5 'vertically from the car 2 and the counterweight 3 run.
  • the drive unit 4 ' according to the embodiment, unlike the elevator according to Figs. 1-3 instead of being placed on a traverse 12 in a wall recess 40. Since the drive unit 4 'is arranged laterally in the wall recess 40 of the cabin 2, a roof 41 of the cabin can be used without any restriction of the shelter for maintenance purposes.
  • the upright arrangement of the drive unit 4 ' is arranged laterally in the shaft 6 such that in the case of vertical projection of the car 2 or the car roof 41 into the plane of the drive unit 4' no overlapping of the same is given or the drive unit 4 'next to the car 2 is arranged. In this way, the entire cabin roof 41 can be used for maintenance purposes. It is understood that the cabin 2 to maintain a provided in the upper region of the shaft 6 shelter occupies an upper end position, which is provided below the drive unit 4 '.
  • the traction sheave 10 'to the guide roller 11' laterally offset from each other to be to spare the cable outlet or the cable inlet or the supporting cable 5 'and the traction sheave 10' and the guide roller 11 '.
