Definitions

  • the present invention relates to a linear hydraulic winch for continuous operation, comprising a fixed frame in the form of a support plate, a first and a second pair of hydraulic cylinders which extend perpendicular to the support plate and whose fixed elements are fixed to said plate, a first and a second traction blocks, which are connected to the mobile elements of the first and second pairs of hydraulic cylinders respectively.
  • Linear hydraulic winches are well known. They are either of the intermittent operating type (see patent FR 2 498 169) or of the continuous operating type (see FIG. 1 of the appended drawings which schematically represents such a continuously operating winch). With equal traction forces and equal strokes of hydraulic cylinders, known winches with continuous operation have the disadvantage of having a larger overall length than that of winches with intermittent operation. This is due to the fact that in continuously operating winches, the two traction blocks are mounted movable in the winch frame, and to the fact that an additional pair of hydraulic cylinders is provided to move that of the two traction blocks which is usually fixed in an intermittent winch. On the other hand, as their name suggests, the winches with continuous operation have the advantage of making it possible to obtain a continuous movement of the cable, therefore of the load, on which they act.
  • the present invention therefore aims to provide a linear hydraulic winch with continuous operation which has, at equal traction forces and equal strokes of the hydraulic cylinders, a lengthwise dimensions of the same order of magnitude as that of known linear hydraulic winches operating intermittent.
  • the two support members 9 and 10 and the two pairs of hydraulic cylinders 21 and 22 are located on the same side of the support plate 25, only the carrier member 10 being located between the cylinders of the four jacks 21 and 22.
  • the carrier member 9, when active, is supported on a shoe 11 which itself is supported on a transverse piece 27 whose ends are respectively fixed to the piston rods 24 of the two cylinders 22.
  • the carrier member 10 is supported on a shoe 12, which itself is supported on the bottom of a U-shaped part 26, the branches of which are respectively fixed to the piston rods 23 of the cylinders 21.
  • the present invention precisely makes it possible to obtain a winch structure as compact as that of FIGS. 2 and 3 of document FR-A 2 167 951, while greatly reducing the bending stresses applied in service to the piston rods of the cylinders of the two pairs. of cylinders and, consequently, while greatly reducing the wear of the fixed and mobile parts which are in mutual contact, relative to the device of FIGS. 2 and 3 of French patent FR-A 2 167 951.
  • the linear hydraulic winch of the present invention is characterized in that the first and second traction blocks are arranged respectively on either side of the support plate, each of said first and second traction blocks being located between the cylinders of the two cylinders, respectively, of one of the two pairs of cylinders and fixed directly to the movable elements of the first or of the second pair of cylinders, respectively.
  • the known linear hydraulic winch shown in FIG. 1 comprises a fixed frame 1, of rectangular shape, formed by two beams 1a and 1b braced at their ends by crosspieces 1c and ld which are drilled in the middle of a hole 2 through which passes a cable 3.
  • Two traction blocks 4 and 5 are respectively fixed to movable crosspieces 6 and 7, the ends of which can slide in the longitudinal members 1 - a and 1b.
  • the cross member 6 can be moved back and forth with the traction unit 4 by a pair of hydraulic cylinders 8, the cylinders of which are fixed to the cross member 1c.
  • the cross member 7 can be moved back and forth with the traction unit 5 associated with it by a pair of hydraulic cylinders 9 whose cylinders are respectively fixed to brackets 11 respectively fixed to the side members 1a and 1b.
  • Each of the two traction blocks 4 and 5 comprises two clamping members (not shown), in the form of a wedge, which, when they are selectively clamped against the cable 3, cooperate with the latter by friction to pull it.
  • the two tightening members of the traction unit 4 are tightened on the cable 3 and the traction unit 4 is moved by the two hydraulic cylinders 8 in the direction of the arrow G while the traction unit 5, whose two clamping members are loose, is moved in the opposite direction to the arrow G.
  • the traction units 4 and 5 respectively occupy the positions shown in phantom in FIG.
  • FIGS. 2 to 8 the elements of the linear hydraulic winch of the present invention, which have the same function as those of the known linear hydraulic winch of FIG. 1, are designated by the same reference numbers.
  • the frame 1 of the linear hydraulic winch of the present invention is reduced to a single support plate 12, perpendicular to the longitudinal axis of the cable 3, which is pierced in its center with a hole 2 for the passage of said cable.
  • the cylinders 8a of the two hydraulic cylinders 8 and the cylinders 9a of the two hydraulic cylinders 9 are fixed to the support plate 12, the two cylinders 8a being located on one side of said plate and in a first plane perpendicular thereto.
  • the two cylinders SLa are located on the other side of the plate 12 in a second plane perpendicular to said plate.
  • the aforementioned first and second planes are also perpendicular to each other as can be seen in particular in FIG. 5.
  • the piston rods 8b of the two hydraulic cylinders 8 pass through the support plate 12 and are fixed directly to the traction unit 4 which is arranged between the cylinders 9a of the two hydraulic cylinders 9.
  • the piston rods 9b of the two hydraulic cylinders 9 pass through the support plate 12 and are fixed directly to the traction unit 5 which is disposed between the cylinders 8a of the two hydraulic cylinders 8.
  • a linear hydraulic winch with continuous operation is obtained, which is extremely compact.
  • a linear hydraulic winch produced in accordance with the present invention having a traction capacity of 500 tonnes and having hydraulic cylinders whose stroke is 1.8 m, has an overall length of less than 5 m.
  • a known linear hydraulic winch produced in accordance with FIG. 1 having a traction capacity of 500 tonnes and hydraulic cylinders whose stroke is only 1.2 m, has an overall length of approximately 12 m .
  • the traction unit 4 comprises, so known, a frame or body 13 having four walls two by two perpendicular defining an elongated passage with rectangular cross section, in which are arranged two clamping members 14 in the form of a wedge, between which the cable passes 3.
  • Each of the two clamping members 14 has, in known manner, an outer surface 14a which is sloping relative to the longitudinal axis of the cable 3, and can roll, by means of a set of rollers 15, on the inner surface 16a of a support piece 16 which is rigidly fixed to the body 13 and whose inner rolling surface 16a has a slope identical to that of the surface 14a of the corresponding clamping member 14.
  • any relative movement of the two clamping members 14 relative to the body 13 causes, in the direction of said movement, the clamping or loosening of the cable 3 by said clamping members 14.
  • Means are further provided for synchronizing the movements of the two clamping members 14, for moving them between their respective clamping and loosening positions shown in FIGS. 6 and 8, and for keeping the two clamping members 14 in their position Clamping.
