Definitions

  • ABSTRACT The self-reeving tractive device is usable as a hoist
  • pinch roller projects through the housing to squeeze or hold the rope against the drum.
  • the roller grips the rope in cooperation with the drum to force the rope to feed into the groove.
  • the roller again grips the rope so it is continually forced along the groove.
  • the rope leaves the drum at the other end of v 6 O B J 4 84 /M i 24 9 4 R0 228 .0 1 3 W9 .5 7 30 MN m 7 24 74 45 l i 22 /1 9 i u flm M27 0 m M 5 u 2 1 n 4 2 "2 .4 u I 2 mmR m o u Hams u 1 a I i. in d s mm U [F 2 8 5 55 .l. [rl
  • FIG. 1 is a partly exploded, perspective view with parts broken away to show the manner in which the wire rope is wrapped on the drum.
  • FIG. 2 is a longitudinal, horizontal section through the housing with the drum and pinch roller not sectioned.
  • FIG. 3 is a vertical cross section through the traction device at the end from which the rope exits.
  • FIG. 4 is a vertical section through the traction device at the end of which the rope is fed to be wrapped on the drum.
  • the traction drive drum 10 is contained within housing 12 including cylindrical section 14 and end plates 16,18.
  • the drum is journaled in the end plates in bearings 20,22 and is driven by the motor (electric, hydraulic or, for that matter, a hand drive) through shaft 26.
  • Gear 28 on shaft 26 drives gear 30 on jackshaft 32.
  • the pinch roller 34 is fixed on the jackshaft and the roller assembly is journaled in bearings 36,38 in the housing end plates 16,18.
  • the mean radius of gear 28 corresponds to the drum radius plus approximately half the thickness of wire rope 48.
  • the mean radius of gear 30 corresponds to the radius of pinch roller 34 plus half the rope diameter and thus, due to the gear drive, the roller and drum will rotate at the same peripheral speed to smoothly pick up and drive the rope between the drum and roller. Theoretically, the roller would not have to be driven but it is deemed advantageous to drive both the drum and roller so as to maximize the force applied to the wire rope.
  • the housing is extended by means of a further housing member 40 to enclose the motor and gearing.
  • the drum can be provided with longitudinal striations 42 or have a roughened surface to increase the grip of the drum on the wire rope.
  • the inside of the cylindrical portion 14 of housing 12 is provided with a helical groove 44 which starts in alignment with the aperture in rope guide 46.
  • the end is picked up between the rotating drum and the pinch roller and forced into the helical groove and thus is wrapped on and fed along the drum. After each complete revolution the end will again pass between the pinch roller and drum to be re-engaged thereby so the drive force is maintained on the rope to force it through the helical groove.
  • the housing is apertured to permit the tailing roller 50 to engage the rope and hold it firmly against the drum by reason of compressed spring 54 acting on the plunger 52 supporting the tailing roller. The end of the rope then is automatically fed through the aperture 56 and leaves the traction device.
  • the action of the tailing roller is interesting.
  • the spring force is applied through the roller to the rope on a line which would fall below the center of the drum in FIG. 3. This develops a force component tangential to the drum pointing towards the tail i.e., resisting run-out of the line.
  • the tailing force thus obtained is adequate to resist pulling line from the drum. This tailing force would not be obtained if the roller applied the spring force radially.
  • This construction provides automatic reeving of the rope while preventing overriding of the wraps.
  • the rope is fully enclosed to reduce danger of getting ones hand or clothing caught.
  • the proper number of wraps must be used, thus insuring safe operating conditions.
  • the pinch roller is made of resilient urethane which will give an effective spring loading to the engagement of the roller on the rope. Deformation of the roller also obtains a good grip on the rope strands. If desired, the pinch roller could be spring loaded but this is not considered necessary.
  • a traction device comprising:
  • a generally cylindrical housing enclosing the drum and having an internal helical groove positioned close enough to the drum so as to engage and con- 3 fine therein a rope wound directly on said drum surface whereby the rope must follow the groove and is, therefore, forced axially over said surface,
  • a device including a pinch roller projecting through the housing and fixed in position close enough to the drum so as to grip the rope between the pinch roller and the drum.
  • a device in which the pinch roller axis is parallel to the axis of the drum and has an axial length generally corresponding to that of the drum whereby the pinch roller engages the rope along the length of the drum.
  • a device including means driving the pinch roller at the same peripheral speed as the drum.
  • a device including a roller projecting through the housing in proximity to the point where the rope egresses from the housing to engage the rope adjacent the point of egress and hold it firmly against the drum.
  • a device including means driving the pinch roller at the same peripheral speed as the drum.
  • a device in which the pinch roller axis is parallel to the axis of the drum and has an axial length generally corresponding to that of the drum whereby the pinch roller engages the rope along the length of the drum.
