Definitions

  • the invention relates to an elevator with an elevator car and a counterweight which are reciprocally movable in an elevator shaft by means of support means and with counterbalancing means connecting the elevator car and the counterweight and the changing weight of the suspension means on the cabin side and on the Balance counterweight side, wherein a guide means is provided, which guides and stabilizes the compensating means.
  • An elevator has become known with suspension elements and compensating means.
  • the guided by a traction sheave and a deflection roller support means have the purpose of an elevator car and a counterweight in an elevator shaft opposite to move up and down.
  • the purpose of the compensating means is to compensate for the changing weight of the suspension means on the cabin side or on the counterweight side.
  • more meters of the suspension means are on the cabin side or on the counterweight side.
  • the compensating means arranged at one end under the elevator car and at the other end act in terms of length or weight on the cabin side and on the counterweight side in opposite directions to the length or weight of the suspension means on the cabin side and on the counterweight side.
  • the compensating means suspended on the elevator car and on the counterweight form a loop in the shaft pit and can be set into oscillation, in particular at high head.
  • a guide device is provided which comprises the compensating means, guides and stabilizes.
  • a disadvantage of the known device is that in sudden movements of the compensating means, the guide device can be damaged.
  • the invention aims to remedy this situation.
  • the invention as characterized in claim 1 solves the problem of avoiding the disadvantages of the known device and to provide a device which performs the compensating means without being damaged.
  • the advantages achieved by the proposed device are essentially to be seen in the fact that less deep shaft pits are possible than in conventional guide means of the compensating means.
  • a shaft pit depth of slightly more than the radius of the compensating means loop is sufficient.
  • the device is simple in construction, inexpensive and can be retrofitted regardless of the shaft pit depth.
  • the device fits differently constructed compensating means.
  • Fig. 1 shows a schematic representation of an elevator 1 consisting of an elevator shaft 2, in which an elevator car 3 and a counterweight 4 in opposite directions are movable up and down.
  • An unillustrated elevator drive drives the traction sheave 5 and moves the elevator car 3 and the counterweight. 4 in the elevator shaft 2.
  • Fig. 1 is the elevator car 3 on the top floor, the counterweight 4 is located at the bottom.
  • the elevator 1 also has compensation means 8, which have the purpose to compensate for the changing weight of the support means 7 on the cabin side and on the counterweight side.
  • Clamp support means 7 and compensating means 8 a vertical plane E up.
  • compensation means 8 for example, at least one rope or a chain or a sheathed chain are provided.
  • the compensating means 8 suspended on the elevator car 3 and on the counterweight 4 form a loop 12 in a shaft pit 11 and can be set into oscillation, in particular at high head.
  • a guide device is provided which guides and stabilizes the compensating means 8 in the plane E.
  • the compensation means 8 consist on the cabin side of a vertical, first strand 13 and on the counterweight side from a vertical, second strand 14 and in the pit 11 from the loop 12.
  • the forming below a line 1 loop 12 has a radius r, which is half as large as the distance a between the two vertical strands 13, 14.
  • the above-mentioned guide device consists of at least one first guide element 15 and at least one second guide element 16, wherein the guide elements 15, 16 are arranged along the compensating means 8, perpendicular to the plane E and out of the plane of the drawing.
  • the first guide element 15 is arranged between the compensating means 8 and a shaft wall 17 and the second guide element 16 is arranged between the two vertical strands 13, 14 or inside the loop 12.
  • the first guide element 15 is arranged along the path of the compensation means 8 on the counterweight side so that the counterweight 4 can pass.
  • At least one first guide element 15 may also be provided on the cabin side, in particular for large delivery heights. In this case, the guide element can be pivoted away so that the elevator car 3 can pass.
  • first guide element 15 and a second guide element 16 On the counterweight side a pair of forming first guide element 15 and a second guide element 16 is provided, wherein the first guide element 15 above the line 1 and between the compensation means 8 and the shaft wall 17 and the second guide element 16 below the line 1 and within the loop 12 is arranged are.
  • first guide element 15 above the line 1 and between the compensation means 8 and the shaft wall 17 and the second guide element 16 below the line 1 and within the loop 12 is arranged are.
  • a pair may be provided on the cabin side.
  • Fig. 1 are shown on the counterweight side three first guide elements 15. There may also be more or fewer than three first guide elements 15.
  • Fig. 2 shows a plan view of the elevator 1 with the guide elements consisting of 15, 16 guide means.
  • the example, rod-shaped guide elements 15, 16 are perpendicular to the plane E and stand out of the plane and have a linear section 22. In cross-section, the guide elements 15, 16 may be, for example, circular, semicircular, oval, etc.
  • a first guide element 15 is between the compensation means 8 and the shaft wall 17 and a second guide element 16 is between the two vertical strands 13, 14 and disposed within the loop 12.
  • the elevator car 3 is arranged on the elevator shaft 2, the first guide rails 18 and the counterweight 4 is arranged on the elevator shaft 2, second guide rails 19.
  • the guide elements 15, 16 are arranged, for example, on the shaft wall 17 or on the guide rails 18, 19.
  • the first guide element 15 may for example also be connected to the shaft wall at both ends.
  • Fig. 3 shows the operation of the guide means, if the balancing means 8 are set in motion.
  • a designated by P1 first arrow symbolizes the movement of the compensating means 8 in the direction of the shaft wall 17.
  • the compensating means 8 can, especially for many meters compensation means 8 on the counterweight side beat against the shaft wall 17 and thereby strengthen their own sideways movement.
  • the in Fig. 3 crossed out first arrow P1 means that the movement of the compensating means 8 is reduced or limited mainly in the plane E or against the shaft wall 17 by means of the first guide elements 15.
  • a second arrow designated P2 symbolizes the movement of the loop 12.
  • the in Fig. 3 crossed out second arrow P2 means that the movement of the loop 12 is reduced or limited mainly in the plane E by means of the second guide element 16.
  • the movements of the compensating means 8 by the guide elements 15, 16 are not reduced or not limited.
  • Fig. 4 shows details of the guide device, in particular the second guide element 16.
  • a designated P3 third arrow symbolizes a jump motion the loop 12. Such movements occur, for example, when driving the elevator car 3 or the counterweight 4 to a buffer.
  • the loop 12 jumps upwards and deflects the second guide element 16.
  • the second guide element 16 has a defined kink 20 and is deflectable thanks to the kink without damage.
  • the in Fig. 4 crossed out third arrow P3 means that the jump movement of the loop 12 is reduced or limited by means of the second guide element 16.
  • the defined kink 20 may for example comprise a spring element or a hydraulic element.
  • the second spring element 16 may be arranged by means of a fastening device 21 on the second guide rail 19.
  • the surfaces of the rod-shaped guide elements 15, 16 have particularly good sliding properties for the compensation means 8.
  • rod-shaped rollers can also be provided which can be driven by the compensating means 8.
