Definitions

  • the present invention relates to lifting and skidding apparatus comprising a single motor.
  • Document FR-A-389 028 discloses an apparatus of this type in accordance with the preamble of claim 1.
  • the present invention seeks to overcome these drawbacks and has as its object, for this purpose, a device for lifting and translating a load as defined in the characterizing part of claim 1.
  • the device which is the subject of the invention can be used in all cases where, after a vertical or lateral movement, it is desired to obtain a horizontal movement or vice versa without any other motor than the lifting device.
  • the device which is the subject of the invention can be used in all cases where a change of direction is desired with a single means of traction.
  • the lifting system control device can be direct (lever, button box) or radio-controlled.
  • the device according to the invention comprises a monorail 23 comprising a raceway on which a mobile carriage can move.
  • This monorail the profile of which is shown in FIG. 18, has locking points 24 and unlocking points 25, and an adjustment system 26 for the monorail on its support.
  • a device belonging to the carriage makes it possible to support the load between these two points without vertical offset between said carriage and the load.
  • the locking (lifting mechanism side) is effected by an articulated fork 8 having its axis of articulation above the axis of the pulley 20 of the carriage.
  • the locking is effected by articulated links 108 having their axis under or at the level of the axis of the pulley 104 of the carriage and held in the neutral position by two opposing springs. It is understood that the axis of the fork or of the rods can be in front of or behind the pulley of the carriage.
  • the device according to the invention makes it possible to obtain a horizontal displacement of the load without having recourse to any means other than the lifting mechanism. During this movement the load is retained vertically.
  • the monorail is inclined on the side of its end 24.
  • Figures 3 to 8 are views of the devices when the unlocking means is a fork.
  • the unlocking device as shown has two ramps 11 in an arc extending the raceway 1 on each side of the carriage.
  • the fork 2 in the low position (fig.3) is raised by the holding nut 6, when the latter arrives in the high position and engages in the housing 20 of the fork.
  • the rollers 3 roll on the ramps 11 and arrived at the level of the track 1 unlock the carriage which can then roll on the track 1 (fig. 4), and prevent the tilting of the fork.
  • the carriage is composed of the fork 2, the rollers 3, the pulley 4 and the rollers 5 of the pulley.
  • the raceway 1 is formed by two symmetrical guides and supported by an adequate structure allowing the load to be taken up when the pulley comes into abutment on the fork 8 (fig. 5).
  • the traction on the cable continuing, the fork 2 rises and actuates a limit switch 10 which reverses the movement.
  • the raceway 1 being partially interrupted as regards the rollers 3, the rollers 3 of the fork 2 can descend push back the pawls 9 of the fork 8 and release the retaining nut 6 (fig. 6). The load can then be placed on the ground.
  • Figures 9 to 18 are views of the devices when the unlocking means is a link.
  • the unlocking device comprises two ramps in an arc 111 extending the raceway 101 on each side of the carriage.
  • the rollers 105 of the carriage are supported on stops 109.
  • the fork 102 in the low position (fig. 9) is raised by the retaining nut 106 (fig. 10), when the latter arrives in the high position.
  • rollers 107 carried by the fork 102 roll on the ramps 111 and, arrived at the level of the raceway 101, unlock the carriage which can then roll on the raceway 101 (fig. 11).
  • the raceway 1 has the same structure as before.
  • the fork 102 rises under the action of the traction of the cable and actuates a limit switch 110 which reverses the movement.
  • the raceway 101 being interrupted in its part which carries the rollers 103, the fork 102 can pivot down, push the links 108 through the rollers 7 (fig. 13) and release the retaining nut 106 (fig . 14). The load can then be placed on the ground.
  • the retaining nut 106 engages at the end of ascent in the fork 102, the latter by pivoting bears on the links 108 which, by pivoting, push the fork 102 (fig. 15) forming a toggle joint.
  • the rollers 103 pivot, (fig. 16) and the fork, at the end of pivoting, actuates the limit switch 110 which reverses the movement (fig.17).
  • the fork 102 descends and comes to rest on the raceway 101 by means of its rollers 103 (fig. 18), and takes up the load by the retaining nut 106, the carriage descends.
  • the rollers 105 come to the stops 109 and the fork 102 pivots downwards and releases the retaining nut 106 (fig. 9).
  • the retaining nut is composed of a sphere 61 secured to a tube at its lower part. This part is drilled and the upper entry has a flared shape so as not to injure the cable.
  • a rotating stirrup 62 is mounted on a shoulder of the tube and has a length suitable for receiving the cable clamps or the crimping 64 of the cable loop.
  • a pin 65 mounted on the stirrup 62 receives on the one hand the cable loop, and on the other hand the hook 63.
  • the monorail can be moved on its support which makes it possible to position its travel, the distance between locking and unlocking being constant for the same type of device.
  • An axis 31 (fig. 21) slides on its support 32 at the rear of the monorail another axis 33 makes it possible to block the monorail at the desired position on the gantry.
  • the locking device comprises two ramps in an arc of a circle 211 extending the raceway 201 on each side of the carriage, the rollers 205 of the carriage 202 being supported on the stops 209 .
  • Two pairs of rollers 203 and 207 are carried by links 230, 230 ′, pivotally mounted around a common axis 231 carried by the carriage 202 and kept apart by a spring.
  • the rollers 203 roll on the same lower track as the rollers 205 while the rollers 207 roll on an upper track comprising ramps 211.
  • the carriage 202 in the low position (fig. 22) is raised by the retaining nut 206 (fig. 23) when the latter arrives in the high position.
  • the rollers 207 roll on the ramps 211 and, when they reach the level of the raceway 201, unlock the carriage which can then roll on the raceway 201.
  • the rollers 207 also prevent, via their axis, a downward tilting of the carriage 202, and therefore ensure the maintenance of the load without intervention of the cable.
  • the raceway 201 is produced as shown in FIG. 29.
  • the carriage 202 rises by pivoting around the axis of the rollers 205 and actuates a limit switch 210 which reverses the movement.
  • the stops 212 are arranged to allow the rollers 203 and 207 to pass.
  • the carriage 202 pivots downwards, pushes the telescopic link 208 through the rollers 207 (fig. 25) and releases the retaining nut 206 (fig. 26 ).
  • the load can then be placed on the ground.
  • the rod 208 is held in the neutral position by a spring.
  • the axis 231 can descend and release the rollers 230 which tilt backwards (fig. 24) before pushing the rod 208 and coming into contact with an upper ramp 232.
  • this axis 231, combined with the rollers 207 prevents rotation of the carriage in the translation position.
  • a slack detector of known type composed of the fixed rollers 215 and mobile 216, indicates that the cable is slackened by pivoting of the roller 216. The latter actuates a limit switch 217 which controls the stop of the descent.
  • the retaining nut 206 engages at the end of ascent in the carriage 202, the latter by pivoting, causes the axis of the rollers 207 to bear on the fork 233 of the telescopic link 208 which, by pivoting, pushes the rollers 207 forward and brings them back to the upper track (fig. 27).
  • the carriage at the end of pivoting, actuates the limit switch 210 which reverses the movement (fig. 27).
  • the carriage 202 pivots and comes to rest on the raceway 201 by means of the rollers 207 and takes up the load by the retaining nut 206.
  • the carriage starts again pulled forward by a reel 214 (fig. 28) or any other system on the horizontal raceway.
  • the rollers 205 come to the stops 209 and the carriage 202 pivots downwards, releasing the retaining nut (fig. 22).
  • the locking and unlocking systems can be mobile or placed together on a mobile carriage in order to make these two points variable.
  • the cart can also be fitted with a hauling system that doubles the load.
  • the monorail can be moved on its support, which makes it possible to position its stroke, the distance between locking and unlocking being constant for the same type of device.
  • An axis 242 slides on its support 26 at the rear of the monorail, another axis 241 makes it possible to block the monorail at the desired position on the gantry (fig. 2).
  • the system according to the invention is supported by 3 feet 50 allowing it to be placed on the ground.
  • this method of fixing can be replaced by holes drilled in the support allowing either to place it or suspend it on any support.
