Description

Support platform for workers dealing with maintenance and construction of means of transport}

The present invention relates to a support platform for workers responsible for the maintenance and manufacture of means of transport such as ships, railroad cars, locomotives, airplanes, lorry and the like.

The present invention may be applied to the manufacture / repair of other means of transportation, such as rolling stock, locomotives, airplanes, etc., but in general the following description will describe the shipbuilding field.

It is well known that there are often frequent or special maintenance operations for vehicles such as watercraft. For this purpose, shipyards are equipped with a repair basin where ships are required to be repaired whenever a certain strength of intervention is needed, ie whenever a special infrastructure or special personnel is needed.

In particular, repair / replacement of plated external components or propeller shafts and propeller device components such as propellers, rudders and the like is important. This is because, first of all, these parts are exposed to greater wear and tear, and therefore require more and more repairs. For the second reason, these parts are generally more important in terms of the safety of ship movement. Finally, there is a greater need for specific height work above ground and the logistic difficulty of using complex and bulky machines / equipment.

Typically, shipyards use scaffolding made through the assembly of metal tubes. Alternatively, a lifting electric walkway for construction purposes is used, which should almost always be fixed to the wall. The use of these devices in shipyards appears to be quite dangerous because special workers have to perform complex tasks (cutting, welding, finishing) very frequently, which can lead to life-threatening drops. Because it can.

Therefore, in the shipbuilding field, there is a great need for a facility that can help workers handle their tasks so that they can work on all the external parts of the ship's hull most easily and safely.

Accordingly, the main object of the present invention is to meet the above necessity, and more particularly, through the original combination of parts, by substantially improving the quality of maintenance work on the outside of the ship, repair work ( It is to provide a platform that can improve the productivity of repair work and at the same time improve safety.

According to the present invention, therefore, a support platform for the workers responsible for the maintenance of the means of transport is produced.

In the accompanying drawings, reference numeral 100 denotes in general a support platform for the worker in charge of the maintenance of means of transport, such as a water craft (NT).

In particular, in FIG. 1, the platform 100 is shown standing up to the side of the bow PR of the ship NT, whereas in FIG. 2, the same platform 100 is of the same waterborne NT. The standing state is shown on the side of the stern (PP).

As shown in the comparative examples of FIGS. 1 and 2, walkways (PDNs) in two environments take different forms, so-called 'copying' the profile of the side on which it is built.

Furthermore, in the repair of hull vessel hulls, it is important to keep in mind that these hulls are designed to meet extremely widespread varying technical requirements, which is of great complexity. Indeed, according to the height of the walkway PDN itself relative to the ground, the outer edge BE of the walkway PDN must be adapted each time to fit the level curve CL shown in FIGS. 1 and 2. do.

3A-6C, the platform 100 of the present invention is movably mounted on a wheel (not shown) distributed on a pair of axes (not shown), one of which is motorized. It includes a base carriage (1). Preferably, as shown in the example shown, the wheel moves on a rail (not shown) parallel to the position where the water vessel under repair is placed, for example a shipyard basin.

Alternatively, the carriage 1 can be supported by a tire (not shown). Furthermore, two front sides of the pallet 1, that is, side surfaces corresponding to the front side of the moving direction, are provided with end stop devices with anti-collision safety functions.

In order to increase the stability of the platform 100, at least one pair of feet (PD) is provided that can be expanded if necessary.

Two uprights 2 protrude from the side 1A of the pallet 1, from which the bracket structure 3 extends horizontally above the pallet 1. Since the bracket structure 3 is slidably supported by the uprights 2, although not shown in detail, the rack structure 3 may be hydraulic by a rack and pinion, a worm screw, a chain, a cable, etc., which are obvious to those skilled in the art. It can be raised and lowered as needed to accommodate the operation of the system supplied by -hydraulic, pneumatic, electronic or mechanical circuits.

The bracket structure 3 then supports the walkway PDN having a perimeter railing 4 for preventing the fall accident for the purpose of supporting the maintenance worker.

Depending on the bracket structure 3, the walkway PDN may have a larger or smaller width than the pallet 1.

As shown more clearly below, the walkways (PDNs) are a plurality of short planes (Figs. 9A-9G) mounted on top of each other to be horizontally translatable separately for each other. These include, they are moved in a direction perpendicular to the advancing direction of the carriage (carriage 1) (in the direction of the double arrow (F)).

As shown more clearly below, the short planes 9A-9G are horizontally moved to “imitate” the hull profile as much as possible.

The short planes 9A-9G have a pneumatic sensitive edge (rubber) that can be connected to the control system to shut down the system, while avoiding severe collisions with water vessels, airplanes, rail vehicles and other surfaces. Or manufactured externally from other materials).

As explained below, the movement of the short planes 9A-9G through the appropriate actuator means provides hydraulic, mechanical or electronic circuitry to the various systems described above.

Workers working on a walkway (PDN) need a means of supplying the tools / equipment commonly used for repair / maintenance. To this end, the platform 100 according to the invention is typically connected to circuits for supplying resources such as oxygen, combustion gas, oil, compressed air, water and electricity, the latter of which is the platform 100. ) And its parts.

As is particularly shown in FIG. 4A, the connection is made in a known manner via catenaries 5 for receiving cables / pipes.

The platform 100 also has a retractable staircase SC and at least one control station CC for controlling it of the walkway PDN by controlling the elevation of the bracket structure 3.

The control station CC has a suitable sensor network for managing the programmed logic of the movement of the platform 100 in a manner known to the person skilled in the art.

In this regard, the management system of the control station CC prevents the operation of the bracket structure 3 when the walkway PDN is in the extended position, in order to exclude the possibility of damage to the sea vessel NT. It should be noted that.

One or more operating points (OP) are provided on the bracket structure 3 so that workers can work simultaneously at different points of the walkway PDN on the same side of the water vessel NT, They are supplied via an electrical main and / or hydraulic circuit or the like.

How does the operator move up the height and transverse position to the side of the floating vessel NT due to the movement of the pallet 1 and the rise of the bracket structure 3 (and thus the rise of the walkway PDN)? It should also be noted that working with ease and safety can be achieved.

To avoid the risk of collision with the side of the aquatic vessel NT, the bracket structure 3 is at an appropriate height when the short planes 9A-9G of the walkway PDN are in the withdrawn position (FIGS. 4B and 5B). Need to be located.

When the bracket structure has reached the desired height, one or more short planes 9A-9G are extended to face the sides of the water vessel NT (FIG. 6B), thereby providing a specific position on the height and side as mentioned above. It is possible to form the outer end (BE) in accordance with the hull profile (change) according to.

To ensure that the outer edge BE reaches as close as possible to the hull profile, each pivot CR1, CR2, which is fixedly connected to the last short plane (e.g. 9C in the embodiment of Figure 6A), It has been found that the use of substantially triangular or trapezoidal appendices (APendi, AP1, AP2) is efficient.

The accessories AP1 and AP2 have a pneumatic sensing stage which prevents severe collisions with the surface of the vehicle NT and is electrically connected to the control station CC for system shutdown.

Extend all of the short planes 9A-9G to follow the hull profile of the water vessel NT having the system to be described in detail below, between the last short plane 9A-9G of the extended short planes and the profile of the hull itself. After filling up any available void space, the operator mechanically or manually rotates the at least one fitting AP1, AP2 relative to the hinge CRN1, CRN2 at an angle that allows the operator to approach as close as possible to the curved profile of the hull. Let's do it. After this operation, the operator fixes the relevant positions of the parts AP1 and AP2 (via known means not shown).

It is also noted that the outer edges of the short planes 9A-9G and the outer edges of the accessories AP1 and AP2 are all rectilinear, whereas the profile of the hull generally has a curvilinear extension. It should be noted. Thus, there can be no "imitation" in which the outer edge BE fits completely on the actual profile of the hull side, but it is still admitted to be close to it and belongs to a degree of safety for the platform 100 user.

7A-7C, a walkway (PDN) * in accordance with a second embodiment is shown. The walkway (PDN) * has a short plane 9A * extending substantially over the entire length of the bracket structure 3, and a half length (as shown in FIG. 7B) or short plane 9A *. It includes a series of short planes (9B *, 9B **, 9C *) having a length corresponding to the reduction ratio. Typically, the short plane 9C * is provided with an accessory ((AP1) *) pivoting about the hinge ((CRN1) *), while the short plane 9B ** is provided for the hinge ((CRN2) *). A pivoting accessory (AP2) * is provided.

According to the second embodiment shown in FIGS. 7A-7C, the system for moving the short planes 9B *, 9B **, 9C * is a shot of the first embodiment shown above with reference to FIGS. 6A-6C. More complex and expensive compared to the mobile systems of planes 9B and 9C, but for the second solution (FIGS. 7A-7C), the short planes 9B *, 9B ** and 9C * (possibly attached (AP1 ) *, Which is aligned with (AP2) *), is more "flexibilty" in that it approaches the hull profile more closely.

As shown in the remaining positions of FIGS. 8A and 8B, the walkway PDN includes a plurality of short planes 9A-9G mounted on top of each other.

Of course, in the rest of the configuration of FIG. 8A, substantially only the short plane 9A will actually be used by workers on the platform. In this case, therefore, the surface of the walkway PDN is adapted to conform to the walkable surface 10A of the short plane 9A. Since the remaining short planes 9B-9G are covered by the short plane 9A, an operator working on the platform 100 will not step on it, referring to the configuration of FIG. 8A.

As shown in detail in FIGS. 9A, 9B, 10, the walkable short planes 9B-9G have a relative bearing structure (SP) to which each walkable surface (10B, 10B, 10C, etc.) is fixed. Each includes.

And, each bearing structure SP has a universally "double T beam" in which the two horizontal flanges 11A, 11B each have a height equal to the height of the vertical central web 11C (see Figure 8B). HE-shaped beams 11, UNI_5397- 64, which are known as < RTI ID = 0.0 >. ≪ / RTI > Such bearing structures can be manufactured to have other types and shapes of profiles suitable for the intended purpose instead of the double T beams.

The vertical plate 12, which extends ideally downward in the vertical central web 11C of the beam 11 (FIG. 10), is fixed to the lower horizontal flange 11B of the beam 11 (eg by soldering). . The vertical plate 12 has a shorter length than that of the beam 11. In addition, as shown in FIG. 10, the edge 12 * of the plate 12 lies coplanar with the edge 11 * of the beam 11. Both edges 12 *, 11 * are both positioned to face the vehicle during repair.

As shown in FIG. 8B, the bearing structures SP1 and SP2 of the two short planes 9C and 9D have the beam 11 of the bearing structure SP2 of the short plane 9D as the short plane 9C. Staggered vertically so as to be opposed to the plate 12 with respect to the bearing structure SP2. In addition, a double T-shaped intermediate beam 13 is inserted between the vertical web 11C of the bearing structure SP2 and the vertical plate 12 of the bearing structure SP1.

The intermediate beam 13 also comprises two horizontal flanges 13A, 13B separated by a vertical web 13C. The intermediate beam 13 may be formed from a preformed commercial profile or welded and machined.

Also, as shown in FIG. 10, between one surface 12 ** of the plate 12 of the bearing structure SP1 and the first surface 13c * of the web 13c of the intermediate beam 13. There are a pair of wheels WL1 and WL2, each of which has its own axis of rotation AXL1 and AXL2 fixed to the plate 12.

Similarly, between the second face 13C ** of the web 13c of the intermediate beam 13, its axis of rotation AXL3 relative to the web 11c of the beam 11 belonging to the bearing structure SP2. There is a pair of wheels WL3 and WL4 to which AXL4 is fixed. In addition, the wheels WL1-WL4 in the described system have the function of bearing and resisting lateral thrust.

The operation of the translational mechanism of the short plane (9B-9G) is as follows:

For example, when the actuator (not shown) pushes the short plane 9D in the horizontal direction (and therefore also the associated bearing structure SP2), the associated beam 11 and the associated plate 12 As the wheel moves in the horizontal direction, the wheels WL3 and WL4 roll on a guide consisting of the surface 13C ** of the intermediate beam 13 and the side inner parts of the flanges 13A and 13B. ;

The movement of the beam 11 and the plate 12 of the bearing structure SP2 is such that the wheel ((WL4) *) (see FIG. 10) (located on the plate 12 of the bearing structure SP2) Lasts until advancing to an end stop provided on a track prepared on face 13C ** belonging to structure SP3;

Thus, as the short plane 9D is continually pushed, the intermediate beam 13 also located between the bearing structure SP2 of the short plane 9D and the bearing structure SP3 of the short plane 9E also. Begins to be pulled horizontally;

The horizontal pull movement of the intermediate beam 13 * is both short plane 9E and other short planes 9F and 9G due to the presence of concatenation with other bearing structures (eg SP4). Is converted to the horizontal pulling movement of. However, the other bearing structure is located below the surface 10D and therefore cannot be stepped on by the operator; In any case, as shown in FIG. 13, the total walkable area of the walkway PDN is given by the sum of the available portions of the walkable surfaces 10A, 10B, 10C, 10D;

Now acting as another actuator (not shown) on the short plane 9E, a portion of the walkable surface 10E protrudes and thus requires a means of repair or manufacture (watercraft, rail wagon, locomotive, Expansion of the walkable total surface facing towards the plane, etc.) becomes possible; The lower short planes 9F, 9G will also be pulled according to the same mechanism shown above; Of course, walking on these surfaces is impossible (see FIG. 13).

Although the short planes 9B-9G of FIGS. 8A, 8B, 9A, 9B, 11, 12, 13 are shown descending relative to the previous one, other solutions may be considered, namely, FIGS. 3A, 3B, Each of the short planes 9B-9G may be in an elevated position relative to the previous one as shown in 3C, 6C, and 7C. This will be evident by using the short plane 9G as the first short plane instead of the short plane 9A (as shown in FIGS. 8A, 8B, 9A, 9B, 11, 12, 13).

It will be readily appreciated that certain objectives of the platform of the present invention can be achieved by substantially providing a movable manufacturing zone that can easily form and meet the specific locations required by the operator for the vehicle to be repaired or manufactured. There will be. Furthermore, even in the most various types of embodiments of the present invention, it is possible to supply the materials required by the workers in the best quality. This is always done at the highest level of safety. In this way the quality and productivity of the maintenance or manufacturing operations are substantially increased.
