Definitions

  • the invention relates to a carriage handling and more specifically to a stacker intended preferentially but not exclusively to the transfer of rolling chassis.
  • the invention therefore provides a stacker type again which solves all these problems very advantageous, and which also has many advantages in terms of commissioning, operation, maneuverability, etc ... advantages that will appear on reading the description of the device and its operation.
  • a main object of the invention thus relates to a modular stacker especially for handling rolling chassis with two lower side members lateral resting at their ends on casters, beams on which are fixed two vertical beams supporting lifting organs and mechanisms
  • stacker including the chassis is made up of two sub-assemblies made up each, of a lower spar, of a vertical beam fixed substantially in the middle of the spar, and to the part upper side of a horizontal transmission housing. Both sub-assemblies are interconnected by a single cross-member which is adjustable in width and foldable, and the vertical beam of each sub-assembly serves as a support and guide to a horizontal lifting rail with locking mechanisms to a fixed cabinet.
  • the process rail lifting of each sub-assembly is ensured independently by transmission components housed in the casing and the beam itself.
  • the connecting crosspiece engages on the vertical faces of an S-shaped profiled part which extends the side member towards the rear of the chassis.
  • the locking mechanism of the horizontal rail lifting to a fixed cabinet consists of a finger docking device mounted at the end of a locking rod and cooperating with a return spring, its movement of sliding and pivoting in the rail being controlled by a lever.
  • a lock is fitted on the locking rod and is supported on a profiled spout mounted on a shoe fixed to the side of the lifting rail by one of its ends.
  • the transmission organs for the rail lifting operation of each sub-assembly are consisting of a crank driving by a common rod the first gear of a reduction gear housed in the housing each subset, and means for transmitting the rotational movement of the rod to a worm, extending into the vertical beam and to which is connected the lifting rail.
  • the chassis of the stacker presented in Figures 1 and 2 essentially consists of two subsets (A and B) each formed of a lower lateral spar 8 which supports substantially in the middle a vertical beam 1 on which is mounted a transmission housing 4 developing horizontally, parallel to the beam 8.
  • Said beam extends towards the rear of the chassis by a profiled part 6 in the form of an S, one vertical face of which is at the rear end of the housing 4.
  • the side member is resting on a front wheel 15 mounted madly on its axle, and on a rear caster 5 fitted with a foot brake 7.
  • the two longitudinal members 8 of the two sub-assemblies are connected between them by a connecting cross member 17, adjustable in width, and foldable, as we will see later, a spindle 16 allowing the operation and blocking of the elements of the sleeper.
  • the cross member engages the vertical faces of the profiled parts 6. Each of they receive a vertical jib 2 whose end upper is fixed to the casing 4.
  • the vertical beam 1 serves as a support and guide to a horizontal lifting rail 12 which can move from top to bottom of the chassis under the action of a crank lifting 3, via transmission mechanisms which will be described with reference to FIGS. 4 to 6.
  • the rail 12 supports a docking finger 14 of which the conical end facing the front of the device is intended to enter an opening in the cabinet frame fixed chassis to ensure locking of the rail on said frame.
  • the finger 14 is mounted at the end of a locking rod 24. It cooperates with a return spring 13 and its movement of sliding and pivoting in the rail is controlled by a lever 18 and the locking rod 24.
  • Part upper of the rail 12 is mounted a shoe 10 having like an elongated plate fixed to the side of the rail by one of its ends 23, the other end of the shoe can be lift until the profile spout 25 comes to rest on the rail 12, provided that the locking rod 24, during its displacement forward, has caused said beak thus allowing the upward movement of the hoof.
  • the rail is pierced with a light 21, docking sight.
  • the rail 12 bears on its rear end a rail stop 9.
  • FIG. 2 shows that a ring of declutching 20 actuated by an unlocking lever 19 is associated with the crank 3 to render inoperative if need is, the control mechanism of the lifting rail 12, on the side of the crank.
  • Figures 4, 5 and 6 show the mechanisms that transmit the rotational movement of the crank 3 and raise or lower the rails 12 along the vertical beam 1.
  • the rod 26 drives in the transmission housing 4 a first bevel gear 27 of a reduction gear 28.
  • This first pinion 27 drives a second bevel pinion 29 with axis vertical carrying a toothed wheel 30 on which hangs an endless chain 31, returning to another wheel tooth 32.
  • This is mounted at the top of a worm 33 which extends vertically in the beam vertical 1 and over its entire height.
  • the screw 33 cooperates with a nut 34 secured to the lifting rail 12. It will be noted that this the latter is laterally equipped with a profiled carriage 35 fitted side rollers 36 by which said carriage is guided in the vertical beam 1 also profiled in result.
  • the nut 34 is housed in a nut cage 37 attached to one side of the carriage 35.
  • Figures 7 and 8 correspond to the position folded storage, device.
  • the subset consisting of the side member 8, the vertical beam 1 and the transmission casing 4 is attached to the other sub-assembly, the crosspiece 17 consisting of two elements telescopic 17a and 17b being placed vertically along gallows 2.
  • Screws 38 lock them on the profiled part 6.
  • the pin 16 passing through two orifices of each element crosspiece 17 keeps them in position ( Figure 7).
  • Figure 9 illustrates the first opening phase which consists in horizontally folding the whole of the crosspiece 17 after unscrewing the screws 39 as shown in the arrow. These are replaced when the crosspiece is horizontal.
  • connecting lugs 40 connected together the two sub-assemblies of the chassis. Just remove them, as well as bolts (not visible) placed at the foot of the brackets 2 to separate the two subsets.
  • the user blocks the brakes on foot 7 and make sure that no obstacle can be hooked by the lifting rails, when lifting.
  • crank 3 By acting on crank 3 it adjusts the height lifting rails 12 of the stacker relative to the rails of the cabinet by aligning the indexes and leveling marks available to him. In case the unevenness of the ground would require raising an arm more from the other, it acts on lever 19 and the ring unlocking 20 to uncouple one of the arms, from the crank 3. Another possibility would be to use the rod 26 only on a single bevel gear 27.
  • the user unlocks the foot brakes and pushes the stacker to place as close as possible to the cabinet. He first introduces the conical end of one of the docking fingers 14 in the cabinet entry guide following the execution of the operation through the sighting light 21, and adjusting the level of the rail if necessary using the crank. The operation is identical for the other docking finger.
  • the user unlocks the stacker from the cabinet which returns the latch 11 and the shoe 10 to their position original, the shoe making a non-return stop for rollers of the rolling chassis.
  • the stacker can then move freely and, at the desired location, the user ensures drop the rolling chassis down the rails lifting thanks to the crank.
  • the lock 11 then releases in end of stroke the rolling chassis, moving thanks to its cam 99 which acts on a track 100 of the longitudinal member B.
  • the movement of the stacker on the ground is guaranteed easy way by handles provided at the top of the columns 2.
  • the assembly is very stable thanks to the four casters (5, 15) placed at the end of the side members 8, and there is no significant overhang of the load transported since each vertical beam 1 rises substantially in the middle of the spar 8 and since the lifting rails 12 develop on either side of said beam.
  • the device Due to the lock setting and the independent operation of each lifting rail, the device has great flexibility of use on various soils. We have seen that the possibilities of folding the chassis allow easy storage of the device during periods of non-operation.
