Definitions

  • the invention relates to traction devices acting on a cable by two self-tightening grippers with reciprocating reverse movements for hauling or unhauling the cable.
  • an embossed sheet realization requires the creation of a sort of ribbed box whose various components must be securely assembled.
  • conventional assembly methods, welding or riveting in this case have various drawbacks, in particular the multiplication of corrosion points in areas inaccessible to painting or other protection.
  • the object of the present invention is to provide a spindle anchoring traction device which is designed to avoid the drawbacks mentioned above and which offers great resistance in operation, in particular under heavy load, while allowing an easy embodiment. .
  • the casing of the traction device consists of two identical half-casings assembled around a longitudinal axis, each half-casing comprising a main half-casing made of stamped sheet metal in which are formed chimneys whose dimensions correspond to those of the mooring pin and the axis of the crankshaft of the apparatus and a reinforcing part in stamped stamped sheet metal, mounted on the main half-casing, which has corresponding openings in diameter and in-between the chimneys of the main half-casing and which cooperate with them.
  • Each main casing, and the reinforcement piece associated with it has an anti-corrosion coating.
  • the mooring pin intended to engage in the facing chimneys formed at the front end of the casing of the traction device according to the invention is designed so as not to have the drawbacks of traditional mooring pins to fixing by thread or pin.
  • the spindle has a cylindrical body provided at one end with an operating head and which comprises towards its opposite end a notch coming to lock by rotation on a protruding retaining part secured to the yoke intended to receive the spindle in order 'prevent the axial displacement thereof, a return spring acting on the spindle, in the locked position thereof, to prevent its rotation.
  • the end of the spindle has a flat slightly deeper than the height of the clevis retaining part so that the flat is supported on this projecting part. the positioning of the spindle, before a rotation of the spindle of approximately 180 ° ensures locking.
  • this arrangement implies the creation of an opening allowing the movement of this lever and, by this opening, one can fear the introduction of foreign bodies which can disturb the operation of the device.
  • the traction device according to the invention is advantageously provided with a protection device which almost completely closes the opening of the casing while allowing the free movement of the hauling lever.
  • the protection device has the form of a piece of flexible material, of dimensions suitable for closing the gap between the two half-casings of the device, which has at one end means for hooking to a fixed axis and at its other end a means of attachment to another fixed axis while providing a possibility of longitudinal movement of the flexible part relative to this other fixed axis.
  • this possibility of longitudinal movement is permitted by a buttonhole shape of said other end of the flexible protective part.
  • the protective trap Over its length, has a slot for the passage of the cable passing through the apparatus, as well as an opening allowing the passage of the release control lever.
  • FIG. 1 there is shown the front part of a main half-casing 1 obtained in stamped sheet metal and having inward a chimney 2, intended to receive one end of the anchoring pin of the traction device according to the invention, and another end 3 for receiving one end of the pivot axis of the crankshaft or hauling lever of the device.
  • This main half-casing receives protection against corrosion, for example by zinc plating.
  • the reinforcement piece 4 shown in FIG. 2, made of sheet metal of sufficient thickness and suitably ribbed, is also produced by stamping with holes 5, 6 corresponding at center distance and diameter to the chimneys 2, 3 of the main half-casing. This reinforcing piece 4 is also treated against corrosion.
  • the reinforcement piece 4 is then mounted on the main half-casing, to produce a composite half-casing 7, then an internal burnishing of the chimneys 2, 3 is carried out using of a tool comprising, in addition to the burnishing tool, means for stopping the extension of the rollers in such a way as to obtain bores having precise dimensions which correspond respectively to the mooring pin and to the crankshaft axis.
  • two identical composite half-casings 7 are assembled around an axis of longitudinal symmetry to protect the mechanism (not shown) of the traction device.
  • a mooring pin is more particularly shown intended to be positioned in the openings of the casing formed by the chimneys 2.
  • the spindle is a single piece which has at its right end (looking at Figure 5) a head 11 of a shape allowing easy handling.
  • the body 12 of the spindle of cylindrical shape, has towards its left end looking at FIG. 5 a concentric circular groove 13.
  • a plate 14 extends from the end of the spindle to the groove 13 in which it opens at the bottom of it. Also at the bottom of the groove 13, but diametrically opposite with respect to the plate 14, there is a milling 15 which does not extend this time to the end of the spindle.
  • the spindle also includes, under the head 11, a groove 16 intended to receive the last turn of a spring 17, advantageously of conical shape, the function of which and to urge the body 12 of the spindle to the right of FIG. 5.
  • the groove 16 also serves to house a ring 18 for retaining a link 19 intended to prevent the loss of the spindle.
  • a plate 20 is fixed to the external face of the casing 7 of the device by masking a portion of the hole formed by the chimney 2 receiving the pin, the thickness of this plate being less than the width of the groove 13 and the height of the projecting part of the plate being less than the depth of the groove 13.
  • the maneuver for positioning the spindle will be explained below.
  • the user introduces the body 12 of the spindle into the hole 2 of the casing 7, on the side opposite to the plate 20, the flat 14 of the ends of the spindle being opposite this plate. It then pushes the spindle fully by compressing the spring 17 by turning the body 12 of the spindle either to the right or to the left.
  • the operator can stop pressing and just turn the spindle.
  • the spring 17 slightly returns the spindle to the right of FIG. 5 and this operation is accompanied by a click signaling that the spindle is correctly positioned.
  • the spindle is thus immobilized in rotation and it can also not undergo a clearance translation to the right.
  • the operator For the removal of the spindle, the operator must reverse the maneuvers that led to the introduction and positioning, that is, force the spindle to the left against the action of the spring 17, turn the spindle to bring the dish 14 into contact with the plate 20, then remove the spindle by pulling to the right.
  • FIG. 8 to 11 there is shown a protective device intended to close the open front end of the casing 7 of the traction device according to the invention.
  • the protective device 21 is in the form of a piece molded in one piece from flexible material, for example rubber.
  • the part 21 has, starting from the top of FIGS. 8 and 9, a circular passage 22 intended to provide a second fixing point.
  • FIGS 10 and 11 there is shown the front end of a traction device comprising two half-casings 7 assembled around the mechanism of the device and providing between them a free space for the movement of the hauling control lever 26 mounted pivoting on a transverse axis 27 disposed in the chimneys 3.
  • the protective part 21, which is of a width such that it enters with gentle friction between the two half-casings 7, is put in place to close off the free space spared between them.
  • the passage 22 of the part 21 is fixed on the lower spacer 28 for assembling the half-casings 7, while the intermediate part of the body of the part 21 is guided by another assembly spacer 29 and that the buttonhole 25 hooks onto the upper assembly spacer 30.
  • the hauling control lever 26 protrudes through the opening 24 then that the cable 31 passes through the slot 23.
  • the part 21 effectively protects the mechanism against the introduction of any foreign body.
  • Figure 10 there is shown in solid line the lever 26 and the protective part 21 in the positions corresponding to an extreme rotation of the lever 26 in one direction and, in phantom, the same elements in the positions corresponding to an extreme rotation lever 26 in the opposite direction.
  • the buttonhole 25 which cooperates with the upper spacer 30 and makes it possible to limit the deformations of the part 21 as well as the extension of the latter.
