Definitions
- the invention relates to a flexible and waterproof bag for suspension load test.
- lifting and handling devices such as cranes, hoists, winches, overhead cranes, in the factory or on site, or on an off shore platform, etc.
- heavy loads to restore normal or abnormal conditions of use and make the necessary measurements for the tests.
- inert and massive loads such as metallic masses, both on site and from one site to another, are particularly difficult and expensive.
- a bag for suspension load test comprising an impermeable envelope supported by regularly distributed straps each of which has an upper end intended to be connected to means for suspending the bag and its other end, called the lower end, connected to a connecting ring common to all the straps and arranged under the bag, while a means of emptying the bag is provided.
- the filling can be carried out by the open top of the bag while the emptying is carried out by means of an external evacuation pipe fixed in the lower part of the bag and the free end of which can also be hung on the top of the bag.
- the evacuation pipe is sealed in the envelope and it turns out that, by its shape and the way it is fixed, there is a risk of tearing when handling the bags, thus creating risks of sudden and undesirable emptying of said bag.
- a bag described in GB-2 072 351 A provided with a drain device in the form of a large inner tube which opens outwardly at its lower end, the latter being provided with openings closable which communicate with the interior of the envelope of the bag.
- a drain device in the form of a large inner tube which opens outwardly at its lower end, the latter being provided with openings closable which communicate with the interior of the envelope of the bag.
- the inventor sought a simple and solid system which eliminates or limits the risks of unwanted emptying while possibly allowing the bag to be loaded.
- a bag according to the invention is particularly remarkable in that the emptying and / or filling means comprises at least two parts fixed together and arranged respectively inside and outside the bag, while an annular housing is provided in one of the two parts to receive the connecting ring of said straps and that at least one drain and / or filling conduit passes right through the two parts and the casing to open inside the bag and outwards via a stop valve.
- the drain and / or filling conduit is bent in the external part so as to present its end towards the outside directed in a substantially horizontal plane when the bag is suspended.
- the parts of the emptying and / or filling means are fixed to one another in leaktight manner by enclosing the lower ends. hours of the straps, while the housing for the connecting ring is constituted by an annular groove formed in one of the parts.
- the drain and / or filling conduit is embedded in the outer part and passes through a corresponding bore formed in the inner part, while the tightness of the fixing of the two parts of the drain means and / or filling, is provided by two seals arranged respectively between the inner part and the envelope and between the latter and the outer part.
- the valve control means is accessible by a hollow imprint.
- the invention also provides that at least one other duct can be fitted in the emptying and / or filling means with a view to ensuring, from the outside, measurements inside the bag, such as the measurement of the filling level, the temperature, etc., which was not possible with the prior art from the emptying means.
- the additional measurement conduit can also be provided at its end inside the bag with a disturbance attenuator.
- the external part of the emptying and / or filling means comprises an annular flange which is fixed to the internal part, which is also in the form of an annular flange, by means of annular discs with an outer diameter greater than the inner diameter of the connecting ring and separated from each other by at least one tabular spacer, while the housing of said connecting ring is provided between the annular discs and that the drain pipe and / or filling is partly formed by a tube tightly fixed between the flange of the external part and the internal part, the other part of the drain and / or filling duct as well as the shut-off valve being fixed on said flange of the external part.
- an intermediate annular disc is provided with an outer diameter less than the inner diameter of the connecting ring, the housing of which is formed by the end of the three discs, the intermediate disc. ensuring centering of said connecting ring.
- the impermeable envelope is clamped between the inner part and one of the annular discs of the outer part while forming at the outer periphery of its clamped part, at least one fold ensuring a possibility of movement to said envelope.
- FIG. 1 shows in elevation a bag according to the invention, filled
- FIG. 2 is a bottom view of the bag of FIG. 1,
- FIG. 3 is a sectional view (except the valve elements) of the means for emptying and / or filling the bag of FIGS. 1 and 2 on a larger scale,
- FIG. 4 is a sectional view along IV-IV of FIG. 5, of the type of FIG. 3 but according to another embodiment of the invention.
- FIG. 5 is a section along V-V of Figure 4, without the stop valve.
- the bag shown in the drawings has a load, that is to say filled with water (or of course another liquid), a general shape of a pear ( Figure 1) and has a waterproof envelope 1, here open. on top and supported or supported by straps 2 regularly distributed.
- the straps 2 each have loops (or eyelets) at each of their ends, one of the loops being designed to be fixed to a suspension means provided for example with a hook or the like (not shown) and the another loop being provided to engage on a connecting ring 3 or similar, flexible or rigid and common to all the straps, arranged under the bag ( Figures 2, 3 and 4).
- the straps 2 are held on the casing 1 for example by sleeves 4 but it is understood that it is the straps 2 which provide the support for the load and prevent the casing 1 from bursting.
- the emptying and / or filling means 5 comprises two parts 5a, 5b arranged in the lower part of the bag, respectively inside (part 5a) and at the outside (part 5b) of the envelope 1.
- part 5b there is provided a bent drain and / or filling conduit 10, as shown in FIGS. 3 and 4 so as to extend substantially horizontally when the bag is suspended as shown in FIG. 1, while that it opens towards the outside via an isolation or stop valve 11 arranged in said part 5b, which valve is provided on the outside with a quick coupling 12.
- the conduit 10 passes through the casing 1 and the inner part 5a provided for this purpose with a bore 13, passing substantially at the center of the ring 3.
- the parts 5a, 5b enclose the ends of the straps 2 while an annular housing 6 is formed in one of the parts, here the external part 5b, for housing the connecting ring 3.
- the parts 5a, 5b are fixed to each other, for example, by assembly screws such as 7, while the seal between the parts is ensured by seals 8 and 9 arranged here respectively between the casing 1 and the part inner 5a Goint 8) and between said casing 1 and the outer part 5b Goint 9, here of annular shape and arranged in a housing of said part).
- the conduit 10 is, for example, obtained directly during the molding of the part 5b and it passes through the joint 8.
- the means 5 is also provided here with at least one other conduit 14, also bent, arranged in the parts 5a and 5b in the same manner as the conduit 10, and it therefore also includes a stop valve 15, a connector 16, while it passes through the interior part 5a by a bore 17.
- a disturbance attenuating device 18 diaphragm, venturi, etc.
- valves 11 and 15 can be actuated by indentations, respectively 19 and 20, accessible for example by wells 21, 22 provided in part 5b and visible in dotted lines in FIG. 2, the maneuvering means being keys with or without torque recovery lever.
- the embodiment of Figures 4 and 5 may be preferred because it allows in particular to ensure a certain freedom of movement of the envelope, with equalization of the stresses exerted on it.
- the inner part 5a is in the form of an annular flange, the hollowed-out central part of which constitutes the end of the conduit 10, while the outer part 5b has many elements and in particular an annular flange 23 fixed to the inner part 5a by means of two annular discs 24, 25 with a diameter greater than the inside diameter of the connecting ring 3 and separated from each other by two tubular spacers 26, 26 ', at least part of these parts which may advantageously, in particular for questions of weight and sealing, be made of synthetic material.
- the housing of the connecting ring 3 is produced by the ends of the two discs 24, 25, as well shown in FIG. 4, which also shows an intermediate annular disc 27, with a smaller outside diameter to the internal diameter of the connecting ring 3, which is arranged between the tubular spacers 26, 26 'and which thus ensures centering of said ring 3.
- the bent conduit 10 is formed in part by a tube 28 tightly fixed between the flange 23 of the outer part 5b and the inner part 5a, the other part of the conduit 10, in return for angle, as well as the stop valve 11 being fixed as shown in FIG. 4, on said flange 23, the valve 11 here being controlled by a lever key 32.
- the bag shown can thus easily be placed on the ground, even filled with water, directly or, more particularly for the embodiment of Figure 4, via a foot such as (31) shown in figure 4.
- the means 5 is perfectly fixed to solid elements of the bag, without forcing on the envelope, both empty and filled, and it avoids any additional external accessories.
- the duct 14 meanwhile, shown in Figure 3, allows by connecting any means on the connector 16, to perform measurements for example of the filling level (by pressure measurement), or other from the outside.
