Description

LIFTING DEVICE
The present invention relates to a lift, device eorppnsing s! least one pylon, having a head end and a foot end, a first transmission means, and a moving platform having an apical face and a basal face opposite one another, said platform being mounted cn said pylon and arranged to move between said foot end and said head end of siii at less! one pylon, said pylon supporting, at a first levai a first pulley arranged to be set in rdtation by a motor and to drive said irst transmission means engaged with the first pulley and having a Href end connected to said apical face of said platform, said first transmission means being arranged to move said platform between sild bead: end and said foot end by rotation of said first pulley.
Typically, this device is used to load and unload transport vehicles such as boats, freight ears or truck trailers.
Such a device Is for example teown from document US §,§?!, 1£S which discloses a lift device comprising a pair of vertioai pylons parallel to one another, each pylon cdmphsfhg: a head: and and a foot end.
The lift device further comprises a moving platform arranged to move between the head and and the foot ends of each pylon.
Each pylon supports, on its head end, a notched pulley connected to a transmission arm with a motor arranged to set the notched pulley in rotation at a rotation speed mmm a first stationary rotation axis crossing through the transmission arm, the notched pulley offne first pylon facing; the notched pulley of the second pylon.
Each pulley driving s chain engaged with the notched pulley, said chain being connected Id the apical face of the moving platform and which, when the notehad pulley is rotated under the action of the motor; is driven by the iafteh causing the plattem to move between a loading level and an unloading level thereof.
Conventionat lift devices ars also described in documents JP2Q0310451Ä, JP2002Ö47821, JPHG21443Ö7Ä, EPÖ669278, JP2ÖÖ3118983 and JPH01176798.
Unfortunately, the devices of the state of the art all have a major drawback: during the Icádéig or unloading of the beat it Is constantly necessary fc adapt the lowering speed of the platform as a function of the evolution of the unloading or unloading [sic] level, which does not cease to lower or rise as the boat is loaded or unloaded.
This constraint recuites the repetitive adjustment of the position of the platform for each to- and-fro mo vement by the latter, for example between the loading: level of the boat and a loading level of the plafond from a loading plateau on the dock, during the loading of goods from the dock toward the boat the adjustment can also he done during the unloading of goods from: the boat toward the dock, between the unloading level of the deaf arid anunloadlng level of the platform on the plateau of the dock.
This adjMstmdnt: generally tedious and time-consuming, since it requires vigilance by the operator, who must ensure monitoring of the motor while keeping: attention focused on the lowering or rising movement of the moving piaforrrL Generally, this adjustment is done by performing the lowering movement of the platform that i adipsted by surge In order to avoid any collision between the moving platform and the boat.
Unfortunately, a surging movement of the platform may be a source of stresses that: are generated in reaction to the surges and that act directly on the chain.
The latter may be damaged and break over time, which is In particular the case when the load supported by the platform is heavy.
Furthermore, these stresses can also act on the goods loaded on the platform, which may also be damaged. Typically, if these surges have an excessively high amplitude, tiling of the goods may occur which also constitutes a non-negtigtble risk of accident
There is therefore a real need to design a lift device that makes it possible to bave a lit device operating more safely and more effectively In terme of saving time and logistical support.
This need le offset by having a Sift device as described in the beginning of the document, charsc#nted in that it comprises a first controi means connected to a reguiator of a rotation speed of said first pulley and to a first moving sensor mounted on one of the pylons and free to move along the pylon between said head end and said foot end of said pylon, said first sensor being arranged on the one hand to determine a first position of said moving platform in three-dimensional space, said first position of said moving plattpvn being defined according to a third level situated between a first level corresponding to a low position of said moving platform at the loot end of said: at least: one pylon and a second level corresponding: to a high level of said moving platform situated at the head end of said at least one pylon, and on the other hand, encoding said first position in a first signai designed to be sent to said control means, said first controi means being arranged to process said first signal as input, computing a second reference position separate from the first position of seid moving platform according to a second predetermined threshold height defined between said first position and said second reference position of said inoying pletfomf and next encoding said second reference position In a second signal sent to the regulator arranged to receive the second signai and to next translate it into a variation of said rotational speed of said motor when the moving platform passes through said reference position to approach said first position·
Tfius, the lift device according to the invention allows a feaidims adaptation of the lowering speed of the platform and makes it possible to modulate that speed when the platform approaches the loading or unloading level of the boat, i.e., when the distance between the platform and the first position, said first position corresponding to the loading or unloading leve! of the boat, corresponds to a height equal to or lower than the second ipredeiermined height threshold, in this context, It has quite remarkably and surprisingly been observed that automating the controi of the lowering speed of the platform of the lift device made it possible to save considérante time and expense during the ioading or unloading toe Peat: toe opetotor di fié isit device no longer having to manually' adjust the lowering of toe platform, toe regulation of the movement speed of the latter being fully automated.
Advanfageousiy; the device according to the invente is characterized in that said pylon supports, at a second levet situated below said first level, a second pulley rotating freely, to form a first pair of:pulleys connected to one another by Said first transmission means, said transmission means having a second end connected to seid basal face of said platform toll closes the first transmission meins, said tost transmission means being arranged to move the platform and drive: said second pulley when said first pulley is set in rotation.
Thus, during the lowering, when the first pulley is set in rotation, for example in the clockwise direction, 1 exerts downward traction on the imnsmiesien means and a tension proportional to the rotation speed of the pulley oriented toward the second pulley is generated from the second end of the transmission means connected to the basal face of the platform. This tension primes the lowering of the platform, which is translated downward;
The lowering movement Of the moving pisiform is then governed by setting the first pulley in rptâion at a rotation speed anc no tongar by gravity alone.
During the lowering, the friction forces generated for example by the movement of toe platform along the pylon and that tend to slow this lowering movement can be offset at any time by increasing the rotation speed of the first pulley.
Another advantage of the lift device according to the invention is that It allows a fine control of the movement of the pisiform, i.e., control making: I possible to adapt top: movement speed of the platform instantaneously when the lift device is operaing, thus tor example making i possible to slow the platform whenlhe latter is approaching a loading or unloading level of the vehicle: and to thus reduce the risks of collision between the latter and said platform.
Advantageously, the device comprises a second pylon to-fo^P, with said first pylon, a pair of pylons, said second pylon supporting a first pulley at a first level and a second pulley at a second level situated below said first level, said pulleys being connected to one another by a second transmission means, said transmission means comprising a first end connected to said apical face of said platform and a second end connected to said basal face of said platform, said second transmission means being arranged to drive said second pulley when said first pulley is set in Maion so as to move said platform between an upper position and a lower position.
The presence of a second pylon on the one hand makes it possible to distribute the load earned by the pisiform over an additional bearing point, la.,, said: second pylon, thus stabilizing said lift device, and on the other hand, the presence of the first additional rotating pulley mounted on the second pylon makes it possible to distribute the traction work eri two pulleys Instead of only one and therefore to increase the load on the working platform, at least doubling I, with eoual work parformedby each pulley, in one: particular embodiment, said first pulley Is placed at the head end of said pylon such that if the device is placed at the dock end of a navigable waterway, said first rotating pulley is far enough away from the water level to avoid any contact with the water 1er example in case of flood;, this first pulley in particular being intended to be connected to a motor. in one preferred embodiment of the device according to the invention, the first and second pylons of said pair of pylons are connected to one another at their head end by a rotary axle around which the first pulleys of each of the pylons are set In rotation In a synchronized manner.
The presence-of this axle makes It possible on the one hand to stabilize the two pylons by securing them to one another, arid on the other hand to provide synchronous rotation of the first pulleys such ihateaeh transmission means drives the translate of the platform in a |yndhrtriiz®#:fi»ner; in ohi particularly· advantageous embodiment öf ;the device aceordfog to tne invention, at least one pylon is provided with a guide rar and wherein said platform commises least one first roiling hearing arrangedto plaoed m seid rail,
Preferably, said second pylon is provided with a guide rail and wherein said platform comprises at least one second roiling deárídg arranged to be placed in said second^ rail
The presence of rolling bearings on the platform mounted m the nils pakes it possible to guide the movement of the platform along a translation axis parallel to each pylon, thus preventing any swinging movemsrlts of the pladorm along in axis perpendicular to said translation axis. The swinging movements create additional torsional tensions on the transmission means which, over time, can lead to breaking of the latter;
Preferably. É# lit device according to the invention is designed to be plaoed at the platform end of waterways or railroad tracks.
The height of 7 metersls the minimum: desirabiehelghf to avoid a collision between a boat moving toward the dock and the platform which, when idle, is in the raised seeuoly position, such that it ensures that the iatter cannot come into contact with the hull of the boat
Advantageously, the lift device is characterized in that it comprises a first safety system comprising at least one first spring arranged to connect said apical face of the moving platform to said first end df the transmission means, said first spang feeing associated with: a second sensor for elongation of the spring, said Safety System comprising f second control means connected to said elongation sensor and to an emergency stop module arranged to stop said rotation of said first pulley, said second comrbi means being arranged to process a third signal sent by said; elongation sensor and corresponding to an eiongalon value measured by said elonption sensor, to compare this third signal to a second reference signal corresponding to a threshold; elongation value and: said fourth signal to said emergency stop module arranged to translate said fourth signal into a stop of the rotation; of said first pulley.
In tills way, when the platform is blocked daring its rising; movement, the irst spring connecting the apical face of the platform to the first and of the transmission mains undergoes an elongation caused by the fraction force of the rotation means driven by the first rotating pulley. This elongation is detected by the elongation sensor and transiated by a stop In the rotation of the first pulley when; the elongation vaiue is above a threshold elongation value.

If the blocking of the plsiorm takes place daring the lowering, the second spring oonhectihg the basal face of the platform to the second transmission means undergoes a downward elongation caused by the traction force of the rotation means caused by the first rotating polley. This elongation Is defected by tie elongation sensor and reflected by a stop In the rotation of the first pulley when the elongation value is above a thmsfipid elongation vaiue.
Optionally, said device according ip the invention is characterized in that It comprises a second safety system in which said basal face of the moving platform is provided with a fourth; contact sensor that is a malleable flange connected to said second control means
During lowering, if the apical face of the platform for example comes closer to the upper boundary of the dull at a distance such that the malleable flange comes into contact with the hull and is deformed, the contact sensor reperds a deformation that it converts into a fifth signal sent to the second control means, Which processes that signal and controls the stopping of the device.
In one preferred; embodiment, seid lift device Is characterized in trial at least brie pylon, preferably each pylon, comprises a series of notches aligned along; an edge of a tread surface of the rail, said notches being included In a fourth plane perpendicular to the first plana tengeri to the face of said moving platform, said platform having: two; side faces opposite one another and arranged to connect said apical face to said hasa! face of the moving platform, each of the side faces having a fifth tangent plane parallel to the fourth plane in which the notches are aligned,: each of the side faces being provided with at least one fall arrestor arranged to nest in said notches, said fail arrestor being connected to a pneumatic or magnetic Jack arranged to engage said fall arrestor in one of the notches, the jack being connected to said second control means arranged to command the jack when said rotation of the pulley Is stopped.
