Definitions
- the invention relates to a cable car machine, in particular for mining, with a traction sheave, which is at the same time displaceable as a tensioning device for the rope by an actuator, the force of which is controlled as a function of the torque of the traction sheave.
- Such a cable car machine is known from DE-OS 25 09 059.
- the document makes the proposal, in a cable car machine with two traction sheaves around which the rope is guided in an S-shape, to make one traction sheave no longer simply a tensioning device relative to the other, fixedly mounted traction sheave, but rather the tension force with the torque of the traction sheaves to change.
- the torque depends on the size of the load and the slope at the point on the path where the load is currently located. It is converted into the tensile force of the rope on the rope sheave. The tensile force of the rope must be held on the traction sheave by friction. This is proportional to the clamping force.
- the clamping force can only be kept as high as necessary. This protects the rope in comparison too tight preload, which has to be measured according to the greatest load and is therefore unnecessarily high in most load conditions.
- the proposal fails when a load pulls downhill and braking force has to be applied. Then the actuator should be locked in order to generate a fixed preload as before. This cable car machine could not be introduced.
- the invention has for its object to provide a cable car machine with a tensioning device that adapts to all load conditions.
- the solution consists in a cable car machine of the type described in the introduction, which has only one traction sheave or in which all traction sheaves together form the tensioning device.
- the torque or a variable proportional to it can be in various ways on the rotary drive of the traction sheave or drive slices are tapped.
- the rotary drive of the traction sheave or traction sheaves has a planetary gear, the outer ring of which is rotatably arranged and drive means for the traction drive with an external toothing.
- a support frame 2 on rollers 3 is displaceable, which carries two traction sheaves 6 and 7 in two blocks 4 and 5.
- an endless cable 9 of a cable car is placed, ie an industrial conveyor, between the rails of which one strand of the cable 9, referred to as a cable 10, is guided and takes a train wagon attached to it, while the other strand, referred to as return rope 11, runs underneath or next to the cable car machine from a reverser arranged at the other end of the track.
- a rotary drive 12 for the traction sheaves 6 and 7 has a pump 15 driven by an electric motor 13 via a clutch 14, a hydraulic line 17 leading from the latter to a hydraulic motor 16 and back, and a clutch 18 via which the traction sheaves 6 and 7 are connected approximately the same torque is transmitted.
- a branch line 19 leads from the hydraulic line 17 to a converter 20, from which a lifting cylinder 22 is acted on via a line 21. This is fixed on the one hand at 23 to the base plate 1 and on the other hand engages with its piston rod 24 at 25 on the support frame 2.
- the loading of the lifting cylinder 22 by the converter 20 is proportional to the pressure in the hydraulic line 17 such that the train on the support frame 2 and thus on the rope runs of the railway rope 10 and return rope 11 is always only slightly larger than necessary to prevent the traction sheaves 6 from slipping and 7 to prevent the rope.
- the function of the cable machine as a tensioning device in addition to the function as a drive device can be seen without further explanation: by pulling the lifting cylinder 22 on the support frame 2, the traction sheaves 6 and 7, with the aid of the deflecting rollers 8, tension the rope on its two rope strands, the railway rope 10 and return rope 11.
- they In order to always move the majority of traction sheaves simultaneously in the tensioning direction of the two rope runs, they are moved in the Usually arrange them in a rigid connection of their bearings.
- a support frame 27 on rollers 28 can be displaced on a substructure 26 by means of a chain hoist 29 arranged in the substructure, to which the support frame 27 is connected by a driver 30.
- a bracket 31 with a traction sheave 32 for a rope 33 is arranged on the support frame 27.
- a geared motor 34 engages on the shaft of the traction sheave 32, which is supported on the support frame 27 only via a torque support 35.
- a controller 36 is connected to a dynamometer 37 in the torque arm 35 and a dynamometer 38 in the chain hoist 29 and controls a drive sprocket 39 of the chain hoist 29 in proportion to the size indicated by the dynamometer 37 so that the chain hoist 29 over the support frame 27 and the Traction sheave 32 gives the rope 33 not much more than the required pretension.
- FIG. 3 shows, corresponding to FIGS. 1 and 2, a base plate 40, a support frame 41 with rollers 42, a trestle 43, a traction sheave 44 for a rope 45 and a drive 46.
- the drive 46 comprises a planetary gear 47 with a second output shaft 48 which is driven by the otherwise stationary outer ring or ring gear of the planetary gear.
- the second output shaft 48 acts on a pinion 49, consisting of a toothed rack 50 rigidly connected to the base plate 40 and a pinion 51 arranged in the support frame 41.
- the torque acting in the outer ring or ring gear of a planetary gear is proportional to the torque output by the planetary gear.
- the tensile force generated in the pinion 49 and tensioning the cable 45 is therefore proportional to the torque delivered to the drive pulley 44.
- the gear ratios including the The diameter of the pinion 51 are dimensioned such that the tensile force is somewhat greater than the required rope tension.
- the rope tension may exceed the minimum value by 5 to 10%.
- the ropeway machines with only one traction sheave could also have, in a known manner, at least one deflection roller, by means of which the rope is laid several times over the traction sheave.
- the deflection roller (s) will then be moved together with the traction sheave, preferably in rigid connection with it, in the direction of the sapnn and back.
