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 there is certainly no slack rope formation on this side either is changed, because this could result in considerable disruptions in the cable 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, possibly on or on the existing rails of the transport system, the majority of which Applications do not require a power connection and which brakes the rope during unwinding and keeps it under tension during winding in such a way that slack rope formation is avoided and with the aid 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 revolving traction ropes, rope-driven means of transport, preferably in underground mines, which is characterized by two holding devices for one rope drum each, the non-rotatable with the rope drums connectable parts of the receiving devices are each connected to a hydrostatic drive, which can also be operated as a pump, and the pressure fluid connections 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 the new rope, either through the old rope or through an auxiliary rope, exerts a pull on the reel in the transport system.
  • 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 former 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 prevented even 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 training 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-laying device also called cable winder, ensures that the winding of the used rope or auxiliary ropes takes place 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. Therefore, in this embodiment, it is not necessary that the reeling drum have larger dimensions than the unwinding drum.
  • a rope length measuring device is assigned to at least one receiving device or rope drum.
  • 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 located at certain points within the rope, the one have a larger cross-section than the rope, reach certain critical implementation points present in the transport system. 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 may 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 line connecting the hydraulic fluid connections of both 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 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 with the rope drum located on it can be easily rotated by hand or by other forces. 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 store or even a manually operated pressure medium pump.
  • the drives are designed in such a way that a drive acting as a pump delivers 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, when there is a large rope supply on it, is still small.
  • 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 delivery rate being set as a function of the filling diameter of one or both cable drums.
  • 1 denotes a housing that 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 the application as a motor or pump, their down or drives are rotatably connected to cores 6 and 7.
  • Cable drums 8 and 9 are detachably or fixedly arranged on the cores 6 and 7.
  • 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.
  • the ropes are labeled 13 and 14.
  • the pressure medium supply and drain 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 in more detail with reference to Figure 2.
  • 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 determined from the ratios of the effective diameters of the empty or Calculate drums 2 and 3 filled with rope, adding a surcharge to the calculated 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 4o by the drive 2, which then acts as a motor.
  • the drum 9 can be operated in a corresponding manner.
  • 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.
  • heating of the hydraulic fluid occurs.
  • a sufficiently large hydraulic fluid supply ensures, however, that the heating remains far below critical limits, especially since the device is not used continuously for long periods in practical use, but rather the device has an assumed rope length of 25oo m and an assumed practical rope speed of 1.5 m per second for a winding process less than 30 minutes in operation.
