Abstract

Feather for the manipulation of large tubes, especially plastic tubes, iron or other material with a smooth and continuous surface, such as those used in large water pipes and the like, of the type constituted by a plurality of articulated arms operable by means of hydraulic cylinders, characterized in that its free end incorporates, suspended therefrom, a head which in turn constitutes the support element for a suction cup of large dimensions and of grooved profile, of curvature adapted to that of the tubes to be handled, said suction cup duly connected to a vacuum source, preferably to a vacuum pump, which may be located in said head or in the crane to which the boom belongs.

Description

Pen for handling large tubes.

Object of the invention

The present invention relates to a pen, it is say to the arm of a crane, of the type used for the handling of large tubes, especially large tubes of plastic of employees in fluid conduits and Similar.

The object of the invention is to obtain a pen which has gripping means for said tubes of extremely fast and simple and efficient operation operational

Background of the invention

In fluid installations such as previously mentioned tubes of considerable diameter and length, which must be intercooled coaxially, normally on a canalization previously practiced in the ground, so that the dimensions and weights of said tubes force the need to manipulate them mechanically, using cranes with adequate power, equipped with a pen in turn with dimensions appropriate, able to take the tube from the storage area, by the middle part of it, and moving it to the area of mounting.

For fixing the tube different solutions that go, from the use of belts or chains that embrace the tube body, with the consequent complexity of the fixing these elements to the tube, especially when it is perfectly seated on the ground, until the use of hydraulic clamps that are strangled on the tube, which facilitate the grip of said tube with respect to the systems of clamp mentioned above, but that however can cause damage to the tube if the person handling the crane is not sufficiently skilled or not paying due work Attention.

Description of the invention

The pen proposed by the invention resolves the problem was fully satisfactory before exposed, ensuring extremely fast and easy fixation of the tubes, without the least risk of damage to them, and ensuring the same facility at the time of deposition on the area of mounting.

To do this and more specifically the pen that advocates, from the basic structuring of any pen conventional in terms of the existence therein of sections articulated that allow due mobility of your free limb Within a wide area, it focuses its characteristics on the fact that in said free limb incorporates a fitted head of a vacuum pump that acts on a solenoid valve a suction cup, with the particularity that said suction cup adopts a ribbed configuration, half-round profile and curvature suitable for a perfect adaptation to the tube surface to handle. In this way it is enough to deposit the head on the tube, and more specifically the said suction cup, so that applying the vacuum to it occurs the fixing of the tube to it, being able to said tube be raised and moved to the work area, where is released by simply eliminating the vacuum applied to the sucker.

A swivel coupling of the suction cup to head, or this to the free end of the pen itself, allows the tube to provide a rotating movement so that its guidance is appropriate at the time it will be deposited on the ground, in the same way as said movement rotating allows the suction cup to be positioned parallel to the axis of the tube at the time of mooring of the latter, being able to movement be equally automated through a second solenoid valve

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as an integral part of said description, a set of drawings where with character Illustrative and not limiting, the following has been represented:

Figure 1.- Shows a partial view in perspective of a pen for handling large tubes performed in accordance with the object of the present invention, specifically the tip of it on which it focuses said invention.

Figure 2.- Shows another perspective view of the set represented in the previous figure, now from a lower observation point.

Figure 3.- Shows, finally, another perspective of the pen as a whole, now in a situation of job.

Preferred Embodiment of the Invention

In view of the figures outlined and especially of Figure 1, can be seen as the pen that the invention proposes, like any conventional pen, it is structured by several arms (1) joined together through intermediate joints (2) and assisted by hydraulic cylinders (3), which allow, together with a rotating platform (4) of coupling of the boom to the crane, full freedom of movements for the free limb (6) of said pen within a large area, determined by the size of the pen.

Well, according to the invention, the quoted pen focuses its characteristics on the fact that in the free end (6) thereof incorporates a head (7) that constitutes the support for a suction cup (8) of large dimensions, suction cup that adopts a tile-shaped configuration, as note especially in figure 2, that is a configuration ribbed profile in half-round, for adaptation to the tubes (9) to be manipulated, counting for this purpose with a perimeter joint (10), of rubber or other similar material, which ensures a perfect sealed on the surface of the tube (9) when the depression.

At the bottom of the body (8) of the suction cup is establishes a plurality of holes (11) communicated with a vacuum source, which can be set in turn on its own head (7) or belong to the crane hydraulic system (5), counting in any case the pen with connection means / disconnection to said vacuum source, in order to tie and release the tubes (9).

It only remains to note that the tile (8) is fix the head (7) and / or the latter to the free end (6) of the pen (1) by means of a labeling coupling, in order that the tile (8) can adopt any position, and more specifically in order that when the head (7) descends on a tube (9), the tile (8) adapts positionally to the latter, in order to apply the vacuum and that said tube (9) is tied, as shown Figure 3

In this way it is enough to deposit the tile (8) on a tube (9) and apply the vacuum to the pen, so that said tube (9) is moored and can be moved by the appropriate movement of said pen (1), and reached its final position over this area or point of the ground, the tube (9) is released without rather than disconnecting the suction cup (8) from said vacuum source.

Claims (2)

1. Pen for handling large tubes, especially plastic, iron or other smooth and continuous surface material, such as those used in large water pipes and the like, of the type constituted by a plurality of articulated actionable arms by means of hydraulic cylinders, characterized in that its free end incorporates, suspended from it, a head that in turn constitutes the support element for a large suction cup with a ribbed profile, of adequate curvature to that of the tubes to be handled, being said suction cup duly connected to a vacuum source, preferably to a vacuum pump, which may be located in said head or in the crane to which the boom belongs. 2. Pen for the manipulation of large tubes, according to claim one, characterized in that said suction cup incorporates a perimetric joint in its concave face to ensure the tightness in its adaptation to the tubes to be handled, within which several holes connected to the vacuum source, through an interruptible connection at will, to tie / release the pipes.
