Definitions

  • the invention relates to a lift system, comprising a lift cage, elongate, slack, vertical guide members which are arranged next to the lift cage and top ends of which are connected to stationary points above the lift cage, holding members which are arranged on the lift cage and, in combination with the elongate guide members, fulfil a guide function, and hoisting means which are connected to the lift cage and a stationary point above the lift cage.
  • hoisting means act on a lift cage above its centre of gravity, with the result that it is often not necessary to guide the cage at the sides.
  • the cage is a workbridge which is moved vertically along a building structure, in which case the hoisting means may comprise lifting and latching means which are arranged on each short side of the bridge, for a hoisting cable or latching cable which are attached to high stationary points.
  • the hoisting means may comprise lifting and latching means which are arranged on each short side of the bridge, for a hoisting cable or latching cable which are attached to high stationary points.
  • Another situation involves, for example, a lift cage in a lift shaft of a building in which a hoisting cable engages, from hoisting means arranged at a high point on the building, on the centre of the top side of the cage.
  • a lift system of this nature for transporting people must include fixed, stationary guide means, such as rails, in order to prevent the cage from wobbling and to prevent the formation of dangerous spaces between the floor of the cage and the floor of a storey. Therefore, a suspended bridge system is not suitable for transporting people.
  • the system of the type mentioned in the preamble is characterized, according to the invention, in that the elongate guide members are guide cables, the guide cables are free from the hoisting means, the bottom ends of the guide cables are connected to stationary points below the lift cage, and tensioning means are connected between the guide cables and stationary points, which tensioning means are suitable for tensioning the guide cables while the lift cage is in use, in such a manner that the floor of the lift cage is held substantially horizontally.
  • the lift cage guidance system according to the invention makes it possible to provide a relatively simple and inexpensive installation for hoisting and guiding a passenger lift cage.
  • Fig. 1 shows a tower crane 1 comprising a base 2, a tower 3 which is arranged on the base 2, a lifting arm 4 which is coupled to the top of the tower 3 and a counterweight arm 5.
  • the lifting arm 4 has rails (not shown) over which a hoisting carriage 6 can travel, on which there are pulleys for guiding one or more cables to which a hoisting hook 7 is coupled.
  • a counterweight 8 is attached to the free end of the arm 5.
  • At least two vertical cables 15 are arranged at a distance from the tower 3, for example each between two retaining bars 10, 11 which are optionally temporarily attached to the tower 3.
  • the cables 15 are tensioned with a specific stress, in such a manner that lateral bending of the cables 15 is significantly limited.
  • the cables 15 can be tensioned by tensioning means 16 which are connected to the cables and may be hydraulic means.
  • tensioning means 16 which are connected to the cables and may be hydraulic means.
  • screw tensioning means or a platform which is supported on a thickened section arranged on the cable 15 in question and weights which are stacked on the platform.
  • the cables 15 are used to guide a lift cage 18 which is suitable for transporting people.
  • the lift cage 18 On the top side, the lift cage 18 has gripper members 19 which each engage around an associated cable 15.
  • the gripper members 19 (or guide pieces) can slide or roll along the length of the cable 15 in question.
  • gripper members 19 of this nature are also arranged at the bottom of the cage 18. This ensures that, given a suitable tensile stress in the cable 15, the floor 20 of the cage 18 will always form the same angle, in particular horizontally, with respect to the cable 15. Consequently it is sufficient, given a suitable tensile stress in the cables 15, to use only two cables 15 at a distance from one another.
  • An upright side section 21 which is located approximately between two adjacent cables 15 is suitable for the attachment of a hoisting cable of a hoisting installation which is attached, for example, to the top retaining bars 11, or for the arrangement of lifting and latching means for a hoisting cable or latching cable, as with a suspended bridge installation for maintenance work carried out on the outside of buildings. Consequently, it is possible to use a hoisting installation for the cage 18 which uses only one hoisting cable. Consequently, the hoisting means, for example the hoisting means which are attached to the top retaining bars 11 or the lifting and latching means which are arranged on the cage 18, can be of simple and therefore relatively inexpensive design. Moreover, the use of simple hoisting and latching means arranged on the cage provides more space inside the cage 18 for transporting people or allows the cage 18 to be of correspondingly smaller design.
  • the tensioning means 16 are preferably adjustable tensioning means, such as of the hydraulic form mentioned above, and are controlled by drive means 23.
  • the drive means 23 which, if hydraulic tensioning means 16 are used, may comprise a hydraulic pump, are suitable, on receiving an external command, for actuating the tensioning means 16 to a greater or lesser extent, in order to correspondingly vary the tensile strength on the cable 15 which is connected to the tensioning means 16.
  • the external command may comprise a simple on/off function.
  • the lift cage guidance system according to the invention When the lift cage guidance system according to the invention is used in a building crane as shown in Fig. 1, it may be desirable to control the drive means 23 so as to reduce the tensile stress on the cables 15 for the period in which the lift cage 18 remains at the same height and does not hold any people or goods, so that the action of the crane 1 is not adversely affected by the possibility of an excessive tensile stress in the cables 15.
  • the tensile stress which is generated in a cable 15 can be measured by means of a stress sensor 24, which is connected to a measuring and control circuit 25 for controlling the drive means 23.
  • the control means 25 may also be connected to sensors for measuring climatological conditions, such as a wind speed sensor 26, a wind direction sensor 27 and a temperature sensor 28.
  • the control circuit 25 may be suitable for taking into account one or more measured signals obtained by means of the sensors 26, 27, 28 when controlling the drive means 23.
  • the system is suitable for varying the stress in the cables 15, for example in order to prevent differences in stress between the cables 15, to counteract oscillation in the cables 15 and to anticipate the effects of the weather.
  • the lift cage guidance system according to the invention which is explained above for use in a building crane 1 can also be used in shafts of buildings or towers which, over the movement height of the lift cage 18, offer insufficient facilities for securing permanent guide rails and/or where the costs need to be minimized in view of the limited use made of the lift cage 18.
  • Towers of this nature are, for example, towers of modern windmills, which may be higher than 50 m, may have a diameter of more than 4 m and in which a number of platforms are arranged at different heights.
  • it must be possible to guide this cage through holes which are formed in the platforms with little space in between. This is made possible by means of the guidance system according to the invention.
