Description

The field of the invention is that of lifts. More precisely, the invention relates to the equipment installed in the elevator shafts for ensure the movements of the elevator car.

We specify that we mean by elevators not only lifts for people but also freight elevators large.

The invention applies in particular, but not exclusively, to ships, including passenger ships, cargo ships, ships However, the technique according to the invention can similarly be applied to land buildings.

• les rails de guidage pour la ou les cabines ;
• le ou les contrepoids ;
• les rails de guidage pour le ou les contrepoids ;

An elevator is conventionally constituted by the assembly and assembly of a number of constituent parts in the shaft of the elevator. The essential organs for the operation of the lift are:

• the cabin or cabins;
• guide rails for the one or more cabins;
• the counterweight or counterweight;
• guide rails for the counterweight or counterweights;
• machinery;
• traction cables connecting machinery to counterweights and cabins;
• chutes for the circulation of electric cables;
• ...

Generally, the guide rails for the cabins, the guide rails for counterweights, chutes and ladders are grouped together walls of a sheath constituting the envelope of the elevator.

Currently, the assembly of lifts on ships is fully realized during the ship's cocking phase: the different component parts listed above are shipped as parts parts and assemblies, most often by welding, to each other and to different decks of the ship and walls of the elevator shaft.

Knowing that ships equipped with elevators or lifts generally comprise between three and fifteen bridges, it is understood that the Assembly of an elevator in a ship is long and tedious.

As an indication, the installation of a simple elevator (one cabin) on a ship with ten bridges represents a total of approximately 1,200 hours of workforce.

In addition, such an elevator installation implies a level of risk not negligible because of the working conditions in the elevator shaft (work in height, restricted space, projection of welding, ...).

However, the multiplication of the installation operations and the long duration necessary to achieve them tends to confirm or even increase this level of risks.

The purpose of the invention is in particular to overcome the disadvantages of the prior art.

More specifically, the invention aims to propose a new elevator installation technique which significantly reduces the installation time

The invention also aims to provide such a technique that can fit easily into a ship. In this sense, the invention also objective of providing such a technique that does not lead to overload or loss of space.

Another object of the invention is to provide such a technique which to consider cost savings or, at the very least, that does not result in additional costs.

Another object of the invention is to provide such a technique which limits the risks incurred by the staff installing the elevator.

Yet another object of the invention is to provide such a technique which can be used regardless of the height of the elevator shaft.

The invention also aims to provide such a technique that is simple in design and easy to implement.

• au moins une armature porteuse ;
• au moins un rail de guidage pour cabine ;
• au moins un rail de guidage pour contrepoids ;
• des moyens de maintien et/ou de fixation dudit élément à ladite gaine d'ascenseur,

ledit élément étant constitué sous forme d'un ensemble pré-assemblé prêt à être monté dans ladite gaine d'ascenseur caractérisé en ce que lesdits rails de guidage pour cabine et pour contrepoids sont doublés et montés sur ladite armature de telle sorte que ledit élément puisse être monté en position sensiblement centrale dans une gaine d'ascenseur prévue pour deux cabines, dit ascenseur duplex ou multiplex.These objectives, as well as others which will appear subsequently, are achieved by virtue of the invention, which relates to an element intended to equip an elevator shaft, and comprising:

• at least one carrying frame;
• at least one guide rail for a cabin;
• at least one counterweight guide rail;
• means for holding and / or fixing said element to said elevator shaft,

said element being constituted as a pre-assembled assembly ready to be mounted in said elevator shaft, characterized in that said cabin and counterweight guide rails are lined and mounted on said frame so that said element can be mounted in a substantially central position in an elevator shaft provided for two cabins, said elevator duplex or multiplex.

Thanks to the invention, the installation times can be considerably reduced. on board ships or on-site compared to traditional solutions.

Indeed, the number of operations carried out for the installation on board or on Elevator site is considerably limited. The time of presence of workers in the elevator shaft is therefore reduced accordingly.

In addition, the pre-assembly of the element intended to equip the sheath is performed in the factory, under much more comfortable operating conditions than in an elevator shaft.

This reduces the risks to staff who install the elevator, a large part of the assembly tasks already being carried out.

In addition, pre-assembly at the factory makes it possible to envisage the use of fast, accurate, and inexpensive assembly techniques by having example use of welding robots.

Advantageously, the element also comprises at least one chute intended to receive the power supply cable of said cabin elevator, the element advantageously also comprising at least one ladder.

Thus constituted, the element contributes to further reducing the necessary time to the overall installation of the lift, by reducing the time of presence of workers in the elevator shaft.

The installation of a lift consisting of pre-assembled elements according to the invention on a ship with ten decks then requires about 600 hours, reducing installation time by half compared to solutions traditional.

According to a preferred solution, said carrier reinforcement comprises at least a spar for extending horizontally, said guide rail for cabin being mounted on one side of said spar, the other side of said spar bearing at least two supports each secured to a counterweight guide rail, such that said spar and said supports together delimit a space circulation for said counterweight.

Such a frame is space-saving and thus facilitates its storage, its transport and its implementation, while presenting all the traditional features necessary for the operation of the elevator.

Preferably, said armature is integral with at least one bar of consolidation intended to extend substantially vertically.

Such a bar can easily be attached to the frame during the pre-assembly in factory. This bar contributes to the rigidity of the element.

According to one conceivable variant, this bar can be attached so temporary on the frame for the rigidity of the element for transport and boarding or on-site and then be removed once the item has been place, the rigidity of the element being then simply ensured by the rails of cab and counterweight guidance.

The invention therefore applies to any type of elevator, whatever the height of the sheath and the number of cabins present in it.

In this case, the element advantageously comprises at least two spars intended to extend in the same substantially horizontal plane and each carrying at least one guide rail for a cabin and at least two supports each secured to a counterweight guide rail, longitudinal members being preferably connected by at least two sleepers of such so that said carrier frame forms a frame.

According to this arrangement, a design frame is obtained particularly simple and effective, allowing to support all essential organs by presenting a great capacity to withstand the constraints mechanics acting on it.

According to a preferred solution, said frame carries at least one bar, said central bar, extending parallel to said longitudinal members occupying a middle position between them, and carrying at its ends, or in the vicinity of these, said holding means and / or fixing.

Such a bar can be fixed on each bridge and / or between, whether by bolting, welding or dowelling.

Advantageously, said channel or chutes are carried by said or said spars, said ladder or scales being advantageously borne by said central bar or bars.

We thus obtain an element on which are distributed the different organs so that this element occupies a limited space, whether during its introduction into the elevator shaft or once installed in it.

According to a preferred solution, the element comprises at least two carrying frames substantially parallel to each other and connected by said said consolidation bars.

The number of reinforcement constituting the element may vary as much as depending on the number of bridges and / or between-deck and / or distance that separates them. In any case, the more the number of frames is large, the more time it takes to install an elevator including corresponding elements.

We therefore seek to find a compromise between the gain obtained by the pre-assembly elements and the difficulty caused by the transport and implementation of place an element whose dimensions are increased.

• au moins un élément comprenant au moins une armature porteuse, au moins un rail de guidage pour cabine, au moins un rail de guidage pour contrepoids, des moyens de maintien et/ou de fixation dudit élément à ladite gaine d'ascenseur, ledit élément étant constitué sous forme d'un ensemble pré-assemblé prêt à être monté dans ladite gaine d'ascenseur ;
• au moins un module, dit module de fond de fosse, destiné à être rapporté à la base de ladite gaine d'ascenseur et comprenant au moins deux armatures porteuses, l'une présentant des moyens de réception desdits rails de guidage pour cabine, l'autre présentant des moyens de réception desdits rails de guidage pour contrepoids.

The invention also relates to an assembly intended to equip an elevator shaft, characterized in that it comprises:

• at least one element comprising at least one carrying frame, at least one guide rail for a cabin, at least one counterweight guide rail, means for holding and / or fixing said element to said elevator shaft, said element being formed as a pre-assembled assembly ready to be mounted in said elevator shaft;
• at least one module, called pit bottom module, intended to be attached to the base of said elevator shaft and comprising at least two load-bearing structures, one having means for receiving said cabin guide rails; another having means for receiving said counterweight guide rails.

This provides means of cooperation between the element mounted to the base of the elevator shaft and the bottom module of pit. This makes it easier relative positioning as well as the attachment of the base element to the module of background.

In addition, the reinforcements make it possible to distribute the loads exerted on the sheet on which the module is placed. This avoids the need to reinforce at least locally the bottom plate, which is necessary with conventional techniques so that the sheet can withstand the stresses that are exerted on it.

According to an advantageous solution, said bottom module is formed as a pre-assembled assembly ready to be mounted.

This module is therefore pre-assembled at the factory, which leads to the same advantages than those already stated above concerning the pre-assembled elements.

• limiteur de vitesse de la cabine ;
• limiteur de vitesse du contrepoids ;
• amortisseurs de la cabine ;
• amortisseurs du contrepoids.

Preferably, said bottom module carries at least one of the following groups:

• speed limiter of the cabin;
• speed limiter of the counterweight;
• booster dampers;
• counterweight dampers.

This gives a completely pre-equipped module necessary for the proper functioning of the lift and / or ensuring the security functions in this one.

According to an advantageous solution, the element also comprises a floor of machinery, and forming a closure element of said sheath elevator at the upper end thereof.

According to a preferred solution, said floor comprises at least one electrical cabinet, at least one transformer and at least one motor elevator operation and is constituted as a pre-assembled assembly ready to be mounted. This avoids the on-site assembly of the different elements of machinery that usually on made directly on site on a deck plate and / or steer

• producing at least one pit bottom module in the form of a pre-assembled assembly ready to be mounted at the base of said elevator shaft;
• embodiment of at least one element comprising at least one carrying frame, at least one guide rail for a cabin, at least one guide rail for a counterweight, means for holding and / or fixing said element to said elevator shaft, said element being constituted as a pre-assembled assembly ready to be mounted in said elevator shaft;
• placing and fixing said pit bottom module on the base of said elevator shaft;
• placing and fixing at least one element on said bottom module;
• hooking means for holding and / or fixing said element or elements on said elevator shaft.

It is clear through this mounting process that the installation of an elevator according to the invention, that is to say consisting of pre-assembled elements, is essentially reduced to operations of fixing elements on the elevator shaft and some connection and / or coupling the elements together.

According to an advantageous solution, the method comprises a step of setting in place of said floor machinery by simply placing in support and fixing said floor on supports integral with said elevator shaft.

Such a floor is installed in a particularly simple way in the measure where it is sufficient to rest it on its supports and fix it by welding, bolting or dowelling, so time savings can again be obtained from this fact.

Preferably, the prefabricated element will be dimensioned in such a way that it is necessary to assemble two (or three) elements to equip the whole height of the elevator shaft.

Moreover, the pre-manufactured elements according to the invention, as well as the pit bottom modules and machinery floor, are made using any suitable joining technique, for example by welding or bolting.

According to an initial phase, the bottom module of pit is presented, positioned and attached to the base of the elevator shaft.

A guide rail for the cab is fixed in the elevator shaft, on one of the walls of the sheath.

The first element, slipped into the sheath, is positioned relative to the means for receiving the bottom module of the pit, this first cooperating element with the bottom module of pit.

The prefabricated element or elements are threaded into the elevator shaft and attached to it.

In the case of several elements, these are also joined together between them, for example using bolted plates. In addition, in this cases, electrically connected the elements together.

This connection can then be obtained by planning on each of the elements of sections of a length corresponding to that of the elements. according to a variant, one of the elements (preferably, the element mounted last in the upper part), carries the entire length of the wiring that is unrolled. from the corresponding element down to the bottom of the sheath and fixing this cable to the other elements.

The prefabricated elements are designed and assembled so that, in final position, they can be assembled with the free edge presented by the bridges and / or between spans inside the elevator shaft.

This assembly is carried out either by welding or by bolting (in particularly by the technique of "self-welded" studs known as stud Nelson).

In the case of a two-cabin elevator, the elements are assembled so as to occupy a central position, forming a sort of central ridge. For this, the element or elements are threaded into the sheath while being turned by a quarter of turn relative to their final position to facilitate the threading. Once presented at the desired height, the element is rotated about 90 ° on itself in order to be positioned on the support zones of the bridges and / or between correspondents.

According to a final phase, the support floor of the machinery is positioned on supports integral with the sheath.
Of course, the complete assembly includes other conventional steps, concerning wiring, lighting ...
