Definitions

  • the invention relates to a device for winding and unwinding ropes, in particular revolving pull ropes, rope-driven means of transport, preferably in underground mines.
  • Braking is carried out by makeshift braking devices, for example by wooden beams, and can lead to inadmissibly high temperatures in underground mines due to uncontrolled surface pressures, even sparking and fire formation. Considerable personnel expenditure is required both when jacking up the cable drum and when braking.
  • the auxiliary rope or the used rope to be laid down is generally wound up in such a way that an empty rope drum is jacked up and turned by hand to wind up the rope. This also requires considerable personnel expenditure.
  • the rotation of the rope drum and thus the winding of the rope must take place at such a speed that the formation of slack rope is also reliably prevented on this side, since this could result in considerable disruptions in the rope guides. Therefore, it is often not possible to wind up at the speed that corresponds to the minimum speed of the reel pulling the rope. Then the rope must also be pulled by hand in the area of the reel and any power-driven help is omitted.
  • a power drive of the rope drum used to wind up the rope is in the rarest of cases possible, either such drive devices are missing or they cannot be brought to the required position or the required power connections are missing there.
  • the invention has for its object to provide a simple device for winding and unwinding of ropes for the purposes described above, which is compact and easy to transport, optionally on or on the existing rails of the transport system, which in the vast majority of their applications a power connection is not required and which brakes the rope during unwinding and keeps it under tension during winding up so that slack rope formation is avoided and with the help of which the rope can be pulled through the transport system at a considerable time-saving speed.
  • the invention relates to a device for winding and unwinding ropes, in particular rotating traction ropes, rope-driven means of transport, preferably in underground mines, which is characterized by two receiving devices for one soap drum each, the parts of the receiving devices which are non-rotatably connectable to the rope drum
  • One hydrostatic drive which can also be operated as a pump, is connected, and the pressure fluid connection of the one and the other drive can be connected to one another.
  • the drive of the rope drum on which the new rope rests works as a pump, as soon as on the new rope, either through the old rope or through an auxiliary rope in the transport system.
  • existing reel exerts a train.
  • the force required to actuate the pump acts as a counterforce and in this way ensures that the rope pulled by the reel and running off the rope drum is under tension, so that slack rope formation is prevented.
  • the second cable drum to which the auxiliary cable or the old cable is connected, is driven by the pressure fluid which is emitted by the drive of the first-mentioned drum serving as a pump, so that this cable is wound onto the second, initially empty drum and at the same time is held under tension, so that slack rope formation is also prevented in the rope strand located between the reel and the second drum.
  • the auxiliary rope or used rope is wound up without further action.
  • the two receiving devices and drives are arranged in a common housing. This embodiment results in a device that is compact and easy to transport.
  • both receiving devices can be expedient to arrange both receiving devices axially parallel. This leads to particularly small dimensions of the device, which is particularly desirable in underground mines.
  • the receiving devices can be designed as cores in which the drives are arranged. This design leads to a very desirable small width of the device, also in underground mines.
  • a cable laying device is assigned to at least one receiving device or cable drum.
  • This cable spreader also called cable winder, ensures that the used rope or auxiliary rope is wound on the winding rope drum winding in addition to winding and layer by layer.
  • This rope arrangement is as space-saving as possible and corresponds to that which is usually present on the unwinding drum for the new rope. It is therefore not necessary in this embodiment for the winding drum to have larger dimensions than the unwinding drum.
  • At least one receiving device or rope drum can be assigned a rope length measuring device.
  • the rope length measuring device makes it possible to recognize in good time when the unwinding process will be finished. It also makes it possible to recognize in good time when rope connectors, which have a larger cross-section than the rope, reach certain critical implementation points present in the transport system at certain points within the rope. Such rope connections can in particular be arranged between the old and the new rope.
  • the rope length measuring device enables the exact determination of the rope length to be unwound when the entire rope supply is not to be unwound from the unwound drum.
  • the device can be movable on or on the means of transport, e.g. to be attached to a monorail overhead conveyor or to be placed on an industrial conveyor can be.
  • this in no way precludes the device being transported on a truck or similar land vehicle, for example for use with ski lifts, chairlifts, cable cars or similar means of transport, and even being used without being unloaded from it.
  • a shut-off valve is arranged in at least one of the lines connecting the hydraulic fluid connections of the two drives.
  • both lines can also be guided through a directional valve which blocks both lines in one position.
  • the two drives no longer work in the manner described above in such a way that one drive acts as a pump and the hydraulic fluid which it pumps is used to operate the other drive. This results in further possible uses.
  • a pressure relief valve is connected to the pump outlet of at least one drive. This is desirable if the cable drum assigned to this drive serves as an unwinding drum without a cable having to be wound up. Then the drive of this drum works as a pump against the pressure relief valve and maintains tension in the unwound rope.
  • the hydraulic fluid connections of at least one drive can be connected by a lockable shunt.
  • this shunt When this shunt is opened, the drive in question can be easily turned by hand or by other forces using the rope drum located on it. This is particularly desirable when a short rope length is to be pulled off the unwinding drum by hand or a short rope length is to be wound up by hand on the winding drum.
  • At least one pressure fluid connection of at least one drive can be connected to a pressure medium source.
  • the pressure medium source can be a power-driven pressure medium pump, but then a stationary power connection is required, or only, especially above ground, a portable, possibly existing internal combustion engine, but the pressure medium source can also be a hydropneumatic pressure medium storage or even a manually operated pressure medium pump.
  • the drives are designed in such a way that a drive acting as a pump dispenses a larger quantity of hydraulic fluid per revolution than is consumed by the drive acting as a motor per revolution. This ensures that the unwinding drum, if there is initially only a small rope supply on it, is also driven at a sufficient speed when the speed of the unwinding drum is still small when there is a large rope supply on it.
  • the hydraulic fluid not used by the drive acting as a motor is released into the tank via the pressure relief valve.
  • the drive acting as a pump can also be designed as a pump with an adjustable delivery rate, the adjustment of the delivery rate in Depending on the filling diameter of one or both side drums.
  • 1 denotes a housing which accommodates the device.
  • the housing 1 can be attached to a trolley of a railroad track and / or can be placed on a vehicle, particularly on a rail vehicle.
  • Two hydrostatic drives 2 and 3 are arranged in the housing 1. In the exemplary embodiment, these are radial piston motors, the shafts 4 and 5 of which are firmly connected to the housing 1.
  • the drives 2 and 3 can be used either as a pump or as a motor.
  • the rotating parts of the drives 2 and 3, that is, depending on their use as a motor or pump, their drives or drives, are rotatably connected to cores 6 and 7. On the cores 6 and 7, cable drums 8 and 9 are detachably or fixedly arranged.
  • 1 cable guides 10 and 11 are arranged in the housing, at least one cable guide being designed as a cable laying device or cable winder.
  • a cable-laying device or cable winder is a known device which usually has a threaded spindle and which is used for winding a cable onto the associated cable drum winding in addition to winding and layer by layer.
  • the cable winder is assigned to the cable guide 11.
  • a rope length measuring device 12 which is also known per se, is arranged in the housing 1, in the region of the drum 8.
  • the ropes are labeled 13 and 14.
  • the pressure medium inlet and outlet lines of the drive 2 are denoted by 15 and 16, those of the drive 3 by 17 and 18. They lead to a switch box 19, which will be described with reference to FIG. 2.
  • the pressure medium inlet and outlet lines 15 and 16 of the drive 2 and the pressure medium inlet and outlet lines 17 and 18 of the drive 3 are guided to a directional control valve 21.
  • this directional valve 21 connects the line 16 to the line 17 and the line 15 to the line 18.
  • the directional valve 21 blocks all of these lines from one another.
  • a shuttle valve 22 is connected in parallel to the drive 2, from which a line 23 leads to a pressure relief valve 24. From this line 25 leads to the pressure medium tank 20.
  • Both drives 2 and 3 have shunt lines 26 and 27 connected in parallel, in which shut-off valves 28 and 29 are arranged.
  • a line 30 to 33 in each of which a suction valve 34 to 37 is arranged, leads into the pressure fluid container 20.
  • the connections 38, 39 are provided with clutch valves which are closed in the position shown in the drawing.
  • the two drives 2 and 3 are designed so that the drive 2 acting as a pump delivers a larger quantity of hydraulic fluid per revolution than is consumed by the drive 3 acting as a motor per revolution.
  • the required quantity ratio can be calculated on the basis of the ratios of the effective diameters of the empty or rope-filled drums 2 and 3, a surcharge being added to the mathematical ratio. In this way it is ensured that when the drum 8 is rotated by pulling off a rope, the drum 9 is always driven at the speed required to wind up the deposited rope or auxiliary rope.
  • the device can also be used to wind a rope on another rope drum onto the drum 8 or 9.
  • an external pressure medium source is connected to the external pressure medium connection 38 in such a way that the drum 8 is driven in the direction opposite the arrow 40 by the drive 2, which then acts as a motor.
  • the drum 9 can be operated in a corresponding manner. This also makes it possible to pull a new rope located on the drum 8 into the transport system by means of a used or auxiliary rope connected to the new rope and at the same time to wind the old rope onto the drum 9.
  • the external pressure medium source is connected to the external pressure medium connection 39 in such a way that the drum 9 moves in the direction of the arrow 41.
