Definitions

  • the subject of the present invention is an adjustable platform which makes it possible to lower or mount shuttering elements for masonry slabs, or other construction materials, in particular materials.
  • the system described in Great Britain patent 1 152 470 consists of two notched vertical masts along which a stud bar is fixed.
  • the device comprising a movable receiving platform part moving along a vertical part, characterized in that the vertical part is a single mast.
  • This platform is suitable for receiving formwork panels or other materials and materials from below.
  • the single mast can be adjusted in height by stackable elements, for all heights varying from 2 to 6 m and more.
  • This platform is foldable, to reduce its size to allow the passage of doors and access to floors. All these elements constituting the device according to the invention are removable to facilitate manual transport, in the case of difficult access to many floors.
  • This platform consists of elements, identified on the attached drawings, which represent by way of nonlimiting examples an embodiment of this platform.
  • the device comprises a welded chassis 1 on which a mast 3 is fixed in an articulated manner along which a mobile carriage 16 moves, preferably supporting a platform, under the action of a cable pulled by a manual or electric winch.
  • the chassis 1 mounted on four steerable wheels 2 provides the platform with great stability.
  • a single mast 3 elongated in tube form, of rectangular or square section or in profile, is articulated at its base around a horizontal axis; and is adjustable in height by elements 4 which can be dismantled by interlocking; the mast rests on the chassis and is fixed to it by a pin 5 which allows the articulation of the mast around the horizontal axis.
  • a locking system 9 to the winch support 12 keeps the mast in the vertical position, and another locking system 6 to the chassis ensures a second fixing of the mast.
  • a mast head 10 fits on the upper part of the mast or of the elements, and being removable by interlocking carry the two pulleys 11 cable guide each located on either side of the mast.
  • the winch support 12 in tube lattice is articulated 13 on the chassis around two horizontal axes, and held by two struts 14 connecting the upper part of the winch support to the chassis this support thus contributes to the rigidity of the mast and of the 'together, by the locking constituted by the spindle 9.
  • This support carries a manual or electric winch 15.
  • a mechanically welded mobile carriage 16 slides along the mast by means of four rollers 17, the axes of which are mounted on the carriage and the running surface of which rests on at least two rolling tracks located on two opposite sides of the mast.
  • This carriage is actuated by a cable 18 winding on the winch.
  • a winch 15 which winds or unwinds the cable 18 which, passing along the mast and on the pulleys 11 is attached to the mobile carriage and, which has the effect of raising or lowering the mobile carriage.
  • An arrow 19 in folded sheet metal, platform support, is fixed by stirrups 20 on the mobile carriage.
  • a locking system 6 ensures the mast is locked in the vertical position.
  • THE VERTICAL MAT 3 is made up of a single profile, of variable height, mast extension elements which can be nested one after the other, of variable height with sleeves, can be fitted at the head of the mast, to allow to have the height of the device, according to the request of the use, so that the platform reaches the height of 2 m to 6 m and more.
  • the single mast rests on the articulation by the spindle 5 and is blocked by the lock 6 at the rear of the mast in the working position. In the folded position, the mast rests on the cross-member 25 and is locked by the pin 28. At the rear of the mast and at the bottom, a tab 29 welded to the mast, makes it possible to immobilize the carriage 16 by the pin 30 for mounting. or folding, and transporting the device.
  • THE MATTE HEAD 10 fits at the end of the mast, or to the mast elements.
  • a profile 31 forms the bracket and is U-shaped upside down, inside which there are two pulleys 11 and the passage of the cable.
  • the U-profile is horizontal.
  • a flat iron 32 welded to the upper part of the mast head serves as a stop at the end of the travel carriage 16.
  • the profile 31 has a narrower width than the mast, passes through the mast head right through; and the two upper rear rollers of the carriage, can pass on either side of this profile 31 so that the top of the carriage can coincide with the top of the mast.
  • THE WINCH SUPPORT 12 in tube lattice is fixed to the rear end of the chassis by two articulations 13 to allow the folding of the device.
  • the winch support is held by two struts 14, in tubes fixed by pins, removable.
  • a fixing is fixed, to lock the mast by a pin 9 in the working position.
  • a roller 33 fixed on two welded legs 34 facilitates the deflection and support of the cable 18 at the time of the mast mounting and folding operation.
  • the trolley in a first variant for manual winch, is composed of a vertical element 35 made of sheet metal folded in a U shape, this element 35 surrounds the mast on three sides.
  • rollers 17 Two upper rollers at the rear of the mast, and two lower rollers at the front of the mast, these rollers roll on tracks on the rear and front faces and ends of the mast and mast extension elements are also fixed inside, four studs 36 two upper at the front of the mast, and two lower at the rear of the mast, serve as security, and prevent the carriage from pivoting.
  • gussets 38 are arranged on each side of the element 35; they are formed of a vertical part in shape rectangle welded on one side to the element 35, near the end of the U wing; and of a horizontal part 39 in the shape of a triangle, welded to the upper part of the U wing, and to the upper part of the frame 37.
  • a pin 41 receives the loop of the lifting cable.
  • THE MOBILE TROLLEY 16 in a second variant, for electric winch is different from that described above.
  • the manual winch 15 is replaced by an electric motor winch, the control of which is located on the winch support 12.
  • a parachute brake device is installed in the mobile carriage 16, and is capable of stopping in the event of a break in the lifting cable, the fall of the carriage, and of its assembly. Precise description of the system ( Figure 5).
  • an eccentric cam 43 rotates about its axis 44 comes to bear against the mast at the front, and over the entire width of the latter, and blocks the carriage 16.
  • a spring 45 hooked to the element 35 maintains the feeler 46 in abutment against the cable 18 in tension.
  • a brake lining 47 glued against the cam 43, promotes adhesion in contact with the mast.
  • ARROW 19 is a folded sheet metal assembly provided with two stirrups 20 which hook onto the frame 37 of the mobile carriage 16.
  • two vertical tubes 48 serve as platform support and have two pins 22, for adjusting the height of the platform.
  • THE RECEPTION PLATFORM 21 is a folded sheet assembly, two vertical square tubes 49 are perforated every 5 cm to allow the height of the platform to be adjusted according to use.
  • the platform is fixed by pins 22.
  • This platform is covered with a rubber plate, to prevent slipping of the supported material.
  • the cable 18 is wound on the winch drum, or it is unrolled, which has the effect of raising or lowering the mobile carriage 16 and its boom and receiving platform assembly.
  • the winch is fitted with an irreversible automatic brake device.
  • the manual winch can be replaced by a winch with an electric motor, with electro-brake and load limiter.
  • the device is foldable and reduces its size, and facilitates its movement during transport, and allows passage through doors and stairs for access to the floors.
  • Figure 6 shows the device in the descent or ascent position of the mast.
  • Figure 7 shows the folded device with its built-in table and boom elements.
  • This device according to the invention is used for raising or lowering formwork elements for masonry slabs; it can also be used to raise or lower other objects, including equipment, construction materials.
  • This device can be used for many similar purposes.
  • Another variant is to replace the boom 19 by a bucket, a fork, a nacelle or other device; to allow the use of the device as a material lift, stacker, pallet truck, freight elevator, human gondola, or other uses.
  • a longer boom than that described and shown above with one or more hooks, can be used to transform this manual or electric lifting device into a handling machine to lift loads at heights from 0 to 6 meters and more; and particularly where can not access current machines.
