Definitions

  • the present invention regards a group for controlling and guiding the translation of a lifting group or mast for a 2-way, 4-way or multidirectional side-loading lift truck suitable for resolving movement problems of the lifting group movably mounted in the outlet space (well width) of a lift truck in jargon called "side-loading" truck; and in general the present invention regards the problem of correctly guiding the translation movements of the lifting group, in jargon also termed "mast”.
  • the present invention also regards an internal combustion, electrical or hybrid lift truck (lateral, multidirectional, 2-way, 4-way etc.).
  • An one-sided loading lift truck is a vehicle generally comprising a U-shaped (as seen from plan view) frame, which delimits a space termed “outlet space” or “well width” and is mounted on two (front and rear) axles with a pair of wheels each, an engine group typically for the pair of wheels of the rear axle, a driver's cab mounted in front position on the frame, and a lifting group, the so-called mast.
  • One group is also provided for, in jargon "outlet group” or “outlet carriage”, which bears the lifting group and is slidably mounted in the space of the frame, an "outlet space” or “well width” delimited by the U-shaped frame, so as to move the mast along the outlet space (well width) in a direction perpendicular to the longitudinal axis of the side-loading lift truck or vehicle.
  • rollers or sliding blocks The translation movement of the outlet carriage, within and along the outlet space (well width) occurs by means of rollers or sliding blocks, called in jargon "outlet rollers or sliding blocks" intended to slide within and along substantially C-shaped rectilinear guides provided on the sides of the outlet space (well width).
  • the outlet group is provided with adjustable "opposing" rollers or sliding blocks.
  • the opposing rollers are integrated or mounted, e.g. arranged laterally around the pin of the respective outlet rollers, so as to be in sliding contact with the guide walls of the outlet group.
  • the opposing rollers are normally equipped with adjusting screws, and can be adjusted starting from the opposite side by means of mechanical adjuster. In such case, there will be combined rollers.
  • the opposing rollers are rather fragile, and since they are subjected to frequent impacts, their lifetime is rather short, so that they require repeated substitutions.
  • this expedient provides for obtaining the outlet opening in construction phase but not with parallel sides - rather, with substantially tapered sides. This implies that the distance between the guides of the outlet rollers decreases from the interior towards the exterior of the outlet space (well width), typically about 5 - 15mm between the two ends of the outlet space (well width). This means that in its disengagement motion, the outlet group must force and open or better yet mutually move away the guides on which it slides. In this manner, it is assured that the opposing rollers or sliding blocks always remain in contact with their own sliding guide or surface.
  • section difference between the two sides (bottom side and stem side) of a hydraulic cylinder leads to a movement speed during the exit of the carriage that is considerably less than that of the return phase.
  • GB-1 026 794 teaches a vehicle provided with a lifting group having an outlet carriage comprising a plurality of rollers slidingly mounted in respective guides.
  • the rollers are provided with an annular rib or tread designed to slide within a seat delimited by a respective guide.
  • the rollers have a flanged end.
  • JP-2004-075303 relates to a vehicle with a lifting group having rollers slidingly mounted in respective guides and mounted for rotation on support pins.
  • Each roller is provided with an abutting element slidingly mounted in a direction substantially parallel to its respective support pin, between a retracted position and a pushing extended position, in which the abutting element abuts against an inner surface of the guide.
  • JP-2006-117357 and JP-2008-201493 teach respective vehicles having a mast slidingly mounted in a respective outlet space (well width), and aim at solving the problem of guiding the displacement of the mast and its fork carriage.
  • the main object of the present invention is to provide a group for guiding and controlling the translation motion of an outlet carriage or mast-carrier carriage in a 2-way, 4-way or multidirectional side-loading lift truck, which is suitable for blocking movements that are transverse to the exit-return direction of the respective mast-carrier carriage.
  • Another object of the present invention is to provide a guide and control group which is relatively simple and easy to obtain and which ensures a long useful lifetime without reducing the efficiency and the precision of use over time.
  • Another object of the present invention is to provide a guide and control group which is not affected by the so-called "stick and slip” phenomena.
  • Another object of the present invention is to provide a guide and control group, which does not require periodic resetting of the initial geometries of the frame, nor lubrication of the sliding surfaces of the outlet guides.
  • Another object of the present invention is to provide a guide and control group that lacks opposing rollers.
  • Another object of the present invention is to provide a side-loading lift truck or vehicle equipped with a guide and control group as specified above.
  • Another object of the present invention is to provide a 2-way, 4-way or multidirectional side-loading lift truck equipped with an actuation group for the outlet carriage or mast-carrier carriage suitable for ensuring linear, uniform and controlled movements at high precision.
  • Another object of the present invention is to provide a side-loading lift truck, in which the actuation group for the lifting group or mast is suitable for ensuring uniform movement speeds both during exit and return from/into the outlet space (well width).
  • a guide and control group for the translation of a lifting group of a 2-way, 4-way or multidirectional side-loading lift truck, comprising:
  • the regulating or adjusting means comprises a pair of ring nut elements fit on the pin on opposite sides with respect to a respective roller or sliding block, and suitable for being moved in a controlled manner along its respective pin.
  • a lift truck is illustrated with one-sided loading comprising a frame A, a pair of axles (front and rear) on which the frame A is mounted, each axle being equipped with a pair of wheels: rear B and front C, an engine group, a driver's cab D mounted on the frame typically at the front axle C, and a lifting group or mast E.
  • the carriage comprises an outlet carriage or group F, which supports the mast E and is intended to slidably translate within and along a lateral outlet space (well width) G delimited in the frame A, so as to allow the mast E to be moved between an internal or receded position (see Fig. 6 in particular) and an external or exit position (see Fig. 7 in particular) with respect to the bulk of the frame A.
  • an outlet carriage or group F which supports the mast E and is intended to slidably translate within and along a lateral outlet space (well width) G delimited in the frame A, so as to allow the mast E to be moved between an internal or receded position (see Fig. 6 in particular) and an external or exit position (see Fig. 7 in particular) with respect to the bulk of the frame A.
  • the outlet group F is mounted, at two opposite sides thereof that are parallel to the walls of the lateral outlet space (well width) G, on a plurality (two or more) of outlet rollers H, in turn rotatably mounted on a respective pin, substantially horizontal in use, and designed to slide on respective lateral rectilinear guides L secured to the frame A at the outlet space (well width) G.
  • an upper and a lower rectilinear guide are provided for, between which the rollers H slide.
  • rollers H have substantially cylindrical lateral surface for the rolling engagement with a respective rectilinear guide or substantially flat guide portion.
  • Sliding blocks and/or opposing rollers M are then provided for between the outlet rollers H and the guides L.
  • the rectilinear guides L are usually prestressed such that those on one side of the outlet space (well width) are not parallel to the guides on the other side, i.e. the distance L1 between the guides at the external end of the outlet space (well width) is less than the distance L2 at the internal end of the outlet space (well width).
  • the actuation of the outlet group or mast-carrier carriage F is usually assigned to a pair crossed jacks N.
  • a first embodiment is illustrated of a group 1 for guiding and controlling the translation of the lifting group or mast 2 of a 2-way, 4-way or multidirectional side-loading lift truck or vehicle 3 equipped with monocoque frame 3a.
  • the guide and control group 1 comprises an outlet group or outlet carriage 4 having one or more rollers 5 or sliding blocks, usually four or six, i.e. two or three mounted at each side of the guide or control group.
  • Each roller 5 or sliding block is adjustably mounted on its own axle or pin 6, which is substantially horizontal in use.
  • the guide and control group 1 or better yet the outlet carriage 4 usually comprises a pair of plates 4a fixed (e.g. bolted or welded) on the flanks of the mast 2 and from which respective axes or pins 6 extend, which are substantially orthogonal to the translation direction of the mast 2 in the outlet space (well width) 8 delimited in the frame 3a of the side-loading lift truck 3 and bearing on the free end thereof respective rollers 5.
  • the outlet carriage 4 then comprises an intermediate framework 4b for connecting the plate(s) 4a on one side of the mast 2 to the plate(s) 4a on the other side of the mast 2.
  • One or more rectilinear guide members or guides 7a, 7b are then provided for the rollers 5 or sliding blocks.
  • the guides 7a, 7b are mounted on the sides of the outlet space (well width) 8 for the mast 2 delimited by the frame 3a of the side-loading lift truck 3, along which the respective rollers 5 of the guide and control group are intended to roll. More particularly, at each side of the outlet space (well width) 8, a lower guide 7a and an upper guide 7b are provided for, between which one or more rollers 5 or sliding blocks are driven (usually there are two or three).
  • the lower rectilinear guide member 7a has a sliding engagement surface for the roller(s) or sliding block(s) that is turned upward
  • the upper rectilinear guide member 7b has a sliding engagement surface for the roller(s) or sliding block(s) that is turned downward.
  • At least one roller 5 or sliding block has its own external surface, preferably external or external lateral surface 5a of engagement via sliding or rolling on the respective guide(s) 7a, 7b.
  • the external surface 5a is shaped in such a manner as to ensure a suitable slidable shape engagement with a respective rectilinear guide member 7a, 7b, thereby preventing transverse movements, i.e. which are substantially parallel to the pin 6, of each roller 5 or sliding block with respect to the respective rectilinear guide member 7a, 7b.
  • sliding shape engagement in the present invention, it is intended an engagement that as said prevents transverse movements (substantially parallel to the pin 6), and thus an exact correspondence is not intended, one (the roller) the opposite of the other (the rectilinear guide member), with the same size. Rather, a shape engagement is intended which allows the sliding of the outlet carriage 4 and thus of the mast 2 usually longitudinally along the guide or guides 7a, 7b, preventing, as said, transverse movements or movements that are substantially parallel to the pin 6 by the roller or rollers and hence of the respective outlet carriage 4 and mast 2.
  • the outlet carriage is likely to become slightly inclined at its front part at a level slightly lower than at its back part, and thus the front rollers are in engagement with the lower guide 7a, whereas the back rollers are engage the upper guide 7b.
  • the lateral surface 5a has at least one receiving seat portion, such as a slidable receiving seat, or at least one relief engagement portion, sliding with respect to the remaining external lateral surface of the roller or better yet with respect to a cylindrical lateral surface of a conventional roller, while one or both rectilinear guide members correspondingly have at least one relief portion or at least one slidable receiving seat portion for the rolling or sliding shape engagement with a respective roller or rollers 5 or better yet with a receiving seat or relief portion of a respective roller, respectively.
  • a receiving seat portion such as a slidable receiving seat, or at least one relief engagement portion
  • the rectilinear guide members have at least one portion in relief or at least one slidable receiving seat portion with respect to conventional rectilinear guides, the latter as known being substantially flat.
  • the external lateral surface 5a of the roller(s) 5 is concave 5b (with concavity turned towards the exterior), while one or preferably both the lower and upper guides have a corresponding portion in relief 9b for the shape engagement with the respective concave surface 5b of the roller(s) 5.
  • the receiving seat 5b of the external lateral surface 5a is thus in rolling engagement with the relief or projecting portion 9b of the guides 7a, 7b, in a manner such that the engagement via rolling of the relief or projecting portion 9b with the receiving seat portion(s) 5b does not block the rolling movement or sliding movement of the roller 5 or sliding block longitudinally along the guides 7a, 7b, but prevents or blocks transverse movements, i.e. horizontal and parallel to the axle or pin 6, by the roller 5 or sliding block and hence of the outlet carriage 4 on the guides 7a, 7b.
  • the upper rectilinear guide member 7a and the lower rectilinear guide member 7b are symmetrical with respect to each other with regard to a plane of symmetry that is intermediate thereto, and both have a relief portion or a receiving seat portion with respect to a flat guide surface.
  • the guide and control group then comprises means for regulating or adjusting the position of its respective roller 5 or sliding block on the axle or pin 6.
  • the means for regulating or adjusting comprises a pair of ring nut elements 10 fit on the axle or pin 6, on opposite sides from each other with respect to each roller 5 or sliding block and movable on the axis or pin 6 so as to allow the regulation or adjustment of the position of the roller 5 or sliding block horizontally on the axis or pin 6.
  • the ring nut elements are adapted to be moved along the respective pin 6 so as to allow the controlled regulation or adjustment of the position of the respective roller 5 or sliding block, horizontally on the axle or pin 6.
  • the pin or axle 6 is externally threaded, while the ring nuts 10 are internally threaded, such that if it is desired to move a roller 5 on the pin 6, it would be sufficient to move the two ring nuts 10 via screwing/unscrewing on the pin 6, thus causing the movement of the roller 5 on the axle or pin 6.
  • holes or slots 10a can be provided for in the ring nuts 10 in which respective tools are insertable for controlling the rotation or screwing of the ring nuts 10 on the pin 6.
  • the position of the roller/s on the pin 6 can be adjusted as a function of the position of its respective guide and of the distance between the guide on one side (left side in Figures 15 to 17 ) of the outlet space (well width) and the guide on the other side (right side in Figures 15 to 17 ) thereof, since small construction tolerances should be taken into account, which could cause differences in the position of the guide/s, and in the width or transverse size of the outlet carriage, i. e. the distance between left and right guides.
  • rollers 5 can comprise an internal annular portion 11, intended to be threaded on the axle or pin 6, and a movable external annular portion 12 delimiting the external lateral surface 5a, with the interposition between them (between the internal portion 11 and the external portion 12), e.g. with bearing means, such as conical bearings 13, such that the external portion 12 is mounted for rotation on the internal portion 11.
  • bearing means such as conical bearings 13
  • ball bearings with oblique contact conical bearings with double row of rollers, bearings with adjustable rollers, thrust bearing combined with rollers, rollers and/or ball bearings, with (shaped) thrust bearing made of antifriction material.
  • the pair of ring nut elements 10 make it possible to pre-load the bearings, and thus the nut elements 10 are also useful in ensuring proper working of the bearings.
  • the guide and control group could also include sliding blocks, which would engage the respective guides via sliding.
  • the pin or axle 6 is generally rigidly connected, e.g. by means of welding or bolting, to plates 4a mounted (e.g. bolted or welded) on the sides of the mast 2.
  • the guides 7a, 7b can instead comprise an external section 14 that is fixable, e.g. boltable, to supports 15 in turn borne, e.g. welded, to the frame 3a of the truck 3.
  • the guides can be naturally dismountable, or welded to the frame 3a.
  • each support 15 delimits a hollow or cradle-like portion 15a in which the respective external section 14 is fixable, e.g. via screws 16 (which, as will be understood, ensure the possibility of substituting the sections 14); the section 14 has an intermediate portion 14a larger in thickness than the lateral portions 14b and intended to substantially shape engage the hollow or cradle-like portion 15a.
  • each roller 5 is subjected to axial thrusts substantially in the direction of the pin or axle 6, and such thrusts are unloaded on the fixing screws 16. Due to the particular configuration of the support 15, the axial or lateral thrusts are actually supported or sustained by the hollow or cradle-like seat of the supports 15.
  • a lift truck is illustrated according to the present invention that is equipped with a lifting group or mast 2 in rest position ( Fig. 15 ), intermediate position ( Fig. 16 ), and final or “all out” position ( Fig. 17 ).
  • a mast or lifting group 2 can comprise a pair of sections 2a with substantially vertical position, bridge-connected by means of suitable crossbars 2b.
  • a framework 2c is then slidably mounted, in a substantially vertical direction.
  • Such framework 2c supports means for engaging and transporting a load, such as fork-like brackets or forks 2d extending upward from the framework 2c, in a substantially horizontal direction and with free end turned in the direction of disengagement of the mast from the outlet space (well width).
  • the outlet roller or sliding block cannot be moved or in any case it is strongly prevented from being moved in an axial or parallel direction with respect to the pin or axle 6, but it can usually roll (rolling - in the case of a roller) or slide (sliding - in the case of a sliding block) on the respective guides.
  • outlet roller(s) or sliding block(s) according to the present invention are therefore suitable for supporting axial thrusts, which does not occur with the conventional outlet rollers or sliding blocks.
  • the sliding blocks and/or the opposing rollers are not necessary, and a substantially linear prism-shaped or semicircular guide is obtained which allows the translation movement of the lifting group or mast.
  • a substantially linear prism-shaped or semicircular guide is obtained which allows the translation movement of the lifting group or mast.
  • rollers must then be positioned in a relatively precise manner on suitable outlet guides or profiles, and thus they could require an adjustment in axial sense.
  • the guide and control group is also equipped with ring nuts 10, and thus it is also possible to axially adjust the center of application of the radial force.
  • the ring nuts preferably threaded, in fact allow moving, or better yet adjusting, the axial position of the respective roller or sliding block, both for correctly positioning the roller or sliding block on the outlet guides or profiles integral with the frame and for preloading the conical bearings of the roller as a function of the actual load requirements of the mast and the duration expected for the same.
