Definitions

  • the present invention relates to a reeling device for hoses and/or cables, wherein the reeling device includes a rotatable member which is rotated during unwinding or reeling of the hose and/or cable and wherein a spring device is provided to cooperate with the rotatable member such that the spring device a) is stretched when the rotatable member is rotated in an unwinding direction when the hose and/or cable is pulled out from the reeling device, and b) after pulling out the hose and/ /or cable from the reeling device rotates the rotatable member in a reeling direction for reeling the hose and/ /or cable on the reeling device.
  • Reeling devices of the abovementioned type are already known from US-A-4 299 249.
  • the spring device increases the reeling speed of the rotatable member such that the retracting speed of the hose and/or cable is highest at the end of the reeling procedure.
  • the retracting speed of the hose is also increased and can be very high at reeling devices with long hoses or cables and thereby, powerful spring devices, which might cause various problems.
  • a hose stop means at the end of the hose might with great power hit or bang into an outlet housing through which the hose passes, with the risk of damaging the outlet housing or the risk of the reeling device loosening from its attachments or brackets.
  • a hose being retracted at high speed might hit and cause injuries on personell.
  • the object of the present invention has been to eliminate this problem which according to the invention is arrived at by providing the reeling device substantially with the characterizing features of subsequent claim 1.
  • the reeling device is provided with said characterizing features, it is attained that the rotatable member is effectively braken with simple and reliable means.
  • the reeling device 1 illustrated in fig. 1 includes a support 2 mounted on a wall or any other suitable location and having a rotatable member rotatably mounted thereon, said member being mounted to rotate in an unwinding or unrolling direction as well as in a reeling or wind-up direction.
  • the rotatably mounted member can be a drum 3.
  • On the drum 3 there is provided a hose 4 which by hand or in any other way can be pulled out from the drum 3 in a pulling-out direction A, whereby the drum 3 is rotated in an unwinding or unrolling direction AR.
  • the drum 3 cooperates with a spring device 5 including at least one helical plate spring or a similar spring, which is stretched when the drum 3 is rotated in the unwinding direction AR and which has such spring characteristic that the spring force on the drum 3 increases with the number of revolutions thereof in the unwinding direction AR, i.e. the more the hose 4 is pulled out.
  • a spring device 5 including at least one helical plate spring or a similar spring, which is stretched when the drum 3 is rotated in the unwinding direction AR and which has such spring characteristic that the spring force on the drum 3 increases with the number of revolutions thereof in the unwinding direction AR, i.e. the more the hose 4 is pulled out.
  • Reeling devices of the abovementioned type are described in said US patent specification 4 299 249 and are therefore not described in more detail here.
  • the structure and function of these locking devices are also known and therefore, not described in detail, but it should be mentioned that they can be brought in locking position by stop pulling out the hose 4 and they can be released from this locking position by quickly pulling out or snatching the hose 4 a short distance in the pulling-out direction A, whereupon the spring device 5 can rotate the drum 3 in a reeling or wind-up direction UR for retracting the hose 4 in a retracting direction U.
  • An electric brake device for braking the speed of rotation of the drum 3 when said drum is rotated in the reeling direction UR such that the spring device 5 is prevented from imparting to the drum 3 an undesired high speed of rotation in said reeling direction UR.
  • This electric brake device includes an electric machine 8, preferably an electrically operated motor being in generator operation, mounted on the support 2.
  • This electric motor 8 has an output shaft with a gear wheel 9 or similar in movement transferring engagement with a gear ring 10 or similar on the drum 3 for transfer of the rotary movement of said drum 3 to the electric motor 8 such that said motor is operated to generate electric energy.
  • the gear ring 10 is preferably located at such peripheral portions of the drum 3 which have a higher speed of rotation than central portions thereof.
  • the electric motor 8 cooperates with an electric loading device 11 receiving and consuming electric energy generated by said electric motor 8, such that the speed of rotation of the drum is slowed down or lowered when said drum is rotated by the spring device 5 in the reeling direction UR, i.e. when the hose 4 is retracted in the retracting direction U.
  • the consumption of the electric energy occurs by, inter alia, transforming it to thermal energy.
  • the electric loading device 11 may be an electric circuit 12 connected to the electric motor 8, said electric circuit being illustrated in fig. 2.
  • This electric circuit 12 includes two diodes 13, 14, a transistor 15 and a potentiometer 16, and it operates such that the transistor 15 is activated when the electric energy generated by the electric motor 8, i.e. the forward voltage through the diodes 13, 14, at a certain current reaches or exceeds a predetermined threshold value which is chosen in dependence of the desired maximum speed of rotation of the drum 3 in the reeling direction UR.
  • a predetermined threshold value which is chosen in dependence of the desired maximum speed of rotation of the drum 3 in the reeling direction UR.
  • Said threshold value can be varied by means of said potentiometer 16.
  • Fig. 3 illustrates a modified embodiment of the electric loading device 11.
  • This alternative embodiment includes an electric circuit 17 which is connected to the electric motor 8 and which, as the electric circuit 12, has two diodes 13, 14, a transistor 15 and a potentiometer 16, but also a control circuit 18 and a capacitor 19.
  • a control voltage is accumulated in the capacitor 19 and can be fed therefrom to the transistor 15 via the control circuit 18 which has a variable threshold through the potentiometer 16.
  • This electric circuit 17 makes it possible to control and brake or slow down the drum 3 when it is rotated at speeds which are too low to permit control and braking by means of the circuit 12.
  • the diodes 13, 14 in both the electric circuits 12, 17 permit braking or reduction of the rotary speed of the drum 3 only when said drum 3 is rotated in the reeling or wind-up direction UR and not in the unwinding or unrolling direction AR.
  • the electric machine 8 can be an electric motor in the form of a DC motor or as an alternative thereto, a generator.
  • the electric loading device 11 may consist of other electric circuits than those described, the electric machine 8 may cooperate with central portions of the drum 3, e.g. through a gear mechanism which changes up the rotary speed of said central portions, and the drum 3 may be adapted for reeling one or more hoses and/or one or more cables, whereby the hoses may be e.g. hoses for the supply of liquids or gases to work places or extraction of gases from work places or exhaust pipes for vehicles.
  • the reeling device may include another rotatable member 3 than a drum.
  • the rotatable member 3 may instead consist of an arm (not shown) which rotates relative to a non-rotatable reeling and unwinding member.
  • the arm When the hose 4 is pulled out from the reeling device, said arm is rotated relative to the reeling and unwinding member.
  • the arm For reeling or wind-up, the arm is rotated by means of the spring device 5 such that the hose 4 is wound-up on said reeling and unwinding member.
