Definitions

  • the invention relates to traction devices intended primarily for use in everyday life, for example, for pulling a stuck car, as well as in industry as a lifting device.
  • Known power pulley devices consist of blocks assembled into a movable and fixed holder, sequentially enveloped by a rope or chain.
  • the load is suspended from a movable cage, and traction is applied to the branch of the rope, running off from the last of the blocks sequentially enveloped by the rope.
  • the tension of the rope (excluding friction losses) is defined as the quotient of dividing the mass of cargo by the multiplicity of the chain hoist (the multiplicity of the chain hoist is the number of branches of the rope to which the load is distributed).
  • Polyspast clips with a multiplicity of 4-6 are widespread [See, for example: http: // tech-group.pro/blok_polispast].
  • 03/15/81 - prototype containing a drive handle with traction and drive brackets, two drums mounted on the axis, whose cheeks are made in the form of ratchet wheels in contact with spring-loaded dog brackets, the teeth of the ratchet wheels of the drums are directed in opposite directions, and a cable fixed to the drum enveloping a movable unit containing two blocks and an earring for attaching a hook, while the cable attached to the drums, enveloping the blocks, forms a four-fold pulley block.
  • the movable unit is a movable pulley cage with a device for attaching a hook (earring), and a fixed block mounted on the bracket of the winch corresponds to a fixed pulley cage.
  • a disadvantage of the known device is the lack of traction it develops.
  • the objective of the invention was to increase the traction provided by the winch, by increasing the multiplicity of the chain hoist while maintaining ease of maintenance and operation.
  • each clip is made in the form of a housing in which each pulley is mounted on a separate axis tangent to a circle located a plane perpendicular to the axis of application of traction, with the pulleys placed evenly around the circumference.
  • the casing of each cage is made spherical detachable with slots for installing pulleys and holes for the passage of branches of the flexible traction body, and the branches of the flexible traction body are taken into an elastic casing.
  • the figure shows one part of the detachable housing polyspastny 24-fold clips with installed pulleys where:
  • the pulley winch contains movable and stationary pulley casings 1, each of which is made in the form of a spherical split housing of two hemispheres 2, in which each pulley 3 is mounted on a separate axis 4, tangent to a circle located in a plane perpendicular to the axis of application of traction, when this pulleys 3 are placed around the circle evenly.
  • a flexible traction body (for example, a nylon rope) 5 is passed through the pulleys, one end of which is fixed in one of the pulley clips 1, and the other is freely withdrawn.
  • the inventive winch is used as follows.
  • the fixed clip 1 engages with the fixed support (not shown), the movable clip 1 is fixed to the movable object (not shown). Possible sagging can be selected by pulling on the free end of the rope 5. With further action on the rope 5, the movable clip 1 begins to move to the stationary clip 1. In this case, a pulling force with a 24-fold increase is transmitted to the moving object.
  • the inventive tackle winch allows to achieve high multiplicity of transmitted force while maintaining compact size and light weight.
  • the multiplicity of 24 is not a limit, and a small weight is achieved by manufacturing hemispheres 2 of the housing, pulleys 3 and their axles 4 from various types of plastic materials.

Abstract

L'invention se rapporte au domaine des dispositifs de traction que l'on utilise essentiellement au quotidien, par exemple pour remorquer des automobiles en panne, ainsi que dans l'industrie comme dispositif de levage de charges. Le but de a présente invention est d'augmenter l'effort de traction fourni par un treuil, ceci en augmentant la multiplication du plan tout en conservant la simplicité d'entretien et d'exploitation. L'invention concerne essentiellement un treuil à palan comprenant des roues de palan mobiles et immobiles avec un ensemble de poulies (unités) et un élément de traction flexible ; selon l'invention, chaque roue se présente sous forme d'un corps dans lequel chaque poulie est disposée sur un axe distinct tangent à la circonférence se situant dans u plan perpendiculaire à l'axe d'application de la force de traction. Les poulies sont disposées uniformément sur la circonférence. Il est préférable que le corps de chaque roue soit sphérique et amovible avec des entailles pour placer les poulies et des ouvertures pour le passage des branches de l'élément de traction flexible, un capot élastique étant disposé sur les branches de l'élément de traction flexible.
