Definitions

  • the invention relates to a goods lift, in particular an inclined lift, with a rail composed of a plurality of telescopic sections for guiding a goods lift container and with a cable-operated locking or. Unlocking device between two telescopic sections that can be moved relative to each other.
  • a freight elevator with a telescopic rail is known (DE-A-300 1410), which has a plurality of telescopic sections that are relatively movable with respect to one another.
  • all telescopic sections are extended at the same time by operating a cable winch, i.e. A relative movement takes place simultaneously between all telescopic sections - possibly with the exception of the first telescopic section.
  • the known device already has the advantage that by actuating only a single pull cable section, all other pull cable sections can be actuated and thus all telescopic sections can be locked to one another without a long cable being guided over all telescopic sections (with the disadvantage of cable elasticity and thus imprecise response characteristics the locks) is required.
  • the object on which the application is based is to use the known advantages of the solution according to the device of DE-A-30 01 410 to increase the response accuracy and reliability of the lock with reduced effort by preventing the rope extension and rope shortening from being neutralized by rope stretching .
  • the response accuracy and reliability of the lock should be increased as a result.
  • both the rope guides for the actuating rope and the rope guides for the pulling ropes are variable in distance and both rope guides are coupled to one another, the change in distance of the pulling rope is transmitted exactly to the actuating rope and a perfect locking or unlocking is effected.
  • Claims 2 and 3 relate to an embodiment of the coupling between the variable-distance cable guides for the operating cable on the one hand and the traction cable on the other hand using a carrier connecting the two cable guides.
  • Claim 4 characterizes the advantageous assignment of the individual pulling cables or operating cables to the individual telescopic sections; the arrangement of the cable guides characterized in claim 4 can, in a corresponding embodiment of the invention, also be arranged at the lower end of the telescopic sections and serve here for locking or unlocking pivotable cam carriers, pawls or the like.
  • the arrangement of the cable guides for the actuating cable on the one hand and the traction cable on the other hand is such that the movable cable guide of the traction cable undergoes a greater change in distance than the movable cable guide of the actuating cable; this is particularly advantageous because the Traction rope is much longer than the operating rope, so that the greater rope elongation can be neutralized in this way with the same tensile stress.
  • Claims 6 and 7 contain advantageous refinements of the teaching according to Claim 5, according to which there is, as it were, a "translation" between the change in rope length of the actuating rope on the one hand and the traction rope on the other hand.
  • the locking or unlocking device can be returned to its original position, so that the pull cables are moved against the actual direction of actuation.
  • the device according to the invention must be designed in such a way that it is designed as an automatically engaging locking device and the actuation of the pull rope serves for unlocking.
  • the device can be designed such that it is constantly spring-loaded in the unlocked state and the spring force is overcome when the pull rope is actuated and the lock is produced.
  • the telescopic sections 111, IV, V are assigned a locking or unlocking device designated by 1, each consisting of a locking and unlocking device between the telescopic section itself and the next one (cable guides 3 and 4) and a further cable guide (cable guides 11 and 12 ) for tensioning the pull rope 6 ', 6 ", 6"' for the next telescopic shot.
  • the second telescopic section 11 has only cable guides 3 and 4 for actuating the actuating cable 2.
  • the telescopic section I does not require a corresponding locking or unlocking mechanism.
  • the upper end 8 of the last telescopic section V is shown in the upper image plane, the lower end 9 of the next (penultimate) telescopic section IV in the lower image plane.
  • the lower end 7 (see FIG 1) coming pull rope 6, which can be actuated by means of a hand lever 21, is guided in the region of the upper end 8 of this telescopic section over a deflection roller 22 and is fixed to a stop 23 of a carrier 13.
  • the carrier 13 is rotatably supported at a pivot point 18 and is fastened to a rung 14 of the telescopic section V via a bracket 24.
  • Two additional brackets 25 are arranged on the rung 14 and are used for the displacement of cable guides 4 and 12. Similar cable guides 3 and 11 are displaced on the carrier 13.
  • the cable guides are designed as rollers in the illustrated embodiment; the cable guide 4 is preferably designed as a double roller because of the more advantageous cable guide.
  • the cable guides 3 and 4 are wrapped in an actuating cable 2, which with its free ends 5 wraps around the shaft ends 26 of the locking shaft 27.
  • the cable guides 11 and 12 are wrapped in the traction cable 6 ', which is guided from the lower end 9 of the telescopic section IV to the upper end 10 (see FIG. 1).
  • the rope tension of the individual pull ropes 6 ', 6 "and 6"' is adjustable via a tensioning device 19.
  • actuating cable 2 is therefore used exclusively for unlocking.
  • the locking shaft 27 can be rotated in the opposite sense, i.e.
  • the locking cams 28 are basically brought into the unlocking position by means of the spring 20, the actuating cable 2 serving exclusively for locking.
  • Fig. 1 illustrates that corresponding locking or unlocking devices are provided at the upper ends 8, 10, 15 and 16 of the telescopic sections V, IV, III and II, while the upper end 17 of the telescopic section I remains free from such locking; the telescopic section I can be designed to be extended and bent separately.
