Definitions
- the present invention relates to an absorption device impact for a cable stressed in tension, comprising a envelope that can accommodate a portion of cable, the form of the envelope being chosen so that at least part forces generated by a pull on said cable either transmitted to the envelope by said portion of cable, the envelope being susceptible to deformation plastic when said part of the forces exceeds a value predetermined.
- the invention also relates to a protective screen. against falling rocks.
- the protective screens installed in ground in slope to protect areas downstream from falling rocks often consist of cable nets of steel. These nets are composed either of diagonal meshes with crossings fixed by flanges, all connected to a border cable, i.e. rings connected to a border cable by sleeves.
- the large interception structure stones can also be formed of continuous cables, held parallel to each other by guide tubes and lined with a metallic wire net, intended to retain the small stones.
- the protective screens are on the one hand anchored to the ground via patch cables, and are on the other hand connected to posts, fixed or articulated.
- the base posts is mounted on a foundation located in the ground and each post is held in position by upstream and lateral shrouds, attached to the upper part of the post.
- shock absorption devices commonly called brake blocks
- brake blocks are mounted on the shrouds, as well as on the cables junction, possibly the border cables.
- a commonly used type of brake block is made up a cable ring, inserted between 2 sections of cable guy ropes, forming a braking loop using a jaw with two flanges, tightened to a tightening torque predetermined, constituting a friction block.
- the perimeter of the braking loop is often around 1.5 m.
- the morsette, or a similar friction plate can also be directly attached to a portion of cable guyed line in a loop.
- Such brake blocks are described for example in document US 5,435,524.
- a disadvantage major of this shock absorption device results from the fact that the braking is a function of the tightening of the plate friction. Too much tightening prevents the brake block from working, too weak a tightening makes it work too much easily, with low absorption of friction energy.
- the document EP-877122 describes a energy dissipation loop for load-bearing cables comprising one or more fused cable sections mounted in parallel by pairs of sleeves on the carrying cable.
- the fusible cable (s) break before the cable wearer suffers damage.
- This device becomes expensive and difficult to set up when the number of sections fuses per dissipation loop exceeds 3 or 4. Each section breaking before the next section is stressed, the impact of a large stone generates a succession pulsed shocks that could cause the assembly to rupture.
- Document EP-494046 describes an absorption device of the defined input type.
- the cable likely to experience brutal pulls goes to the inside of a tube shaped into one or more turns propeller; the two ends of this tube, which overlap, are connected by a flange. Pulling on the cable causes deformation of the tube, elastic or plastic depending on the intensity of the traction, accompanied by a reduction in diameter of the propeller.
- This device allows absorption reproducible energy in the event of low intensity shocks or average.
- the evolution of plastic deformation of the tube is difficult to predict. It can be located at one point of a turn of the tube, and cause the tube to bend or break at this point, then the rest of the coil is barely deformed.
- the purpose of the present invention is to provide shock absorption devices for cables stressed in traction which do not have the aforementioned drawbacks.
- an object of the present invention is to provide a shock absorption device whose effectiveness is independent of human factors, such as tightening more or less careful, during assembly. It is also a goal of the invention to provide an absorption device whose operation is independent of meteorological factors. It is another object of the invention to propose a shock absorption device which, after implementation only part of its energy absorption capacity, still retains a certain remaining functionality. It is finally an object of the invention to propose a device shock absorption whose operating condition is easy to control during inspections.
- an absorption device of defined type of input shock in which the envelope is consisting of a plurality of fusible elements, arranged so that the part of the forces transmitted by the portion of cable housed in the envelope, causing deformation plastic of the envelope, is exercised sequentially on fusible elements adjacent to this envelope, and which comprises retaining means for retaining a portion of the cable to inside the remaining part of the envelope as long as it there is at least one unbroken envelope member.
- fusible element designates, within the meaning of the present invention, an element likely to undergo a plastic deformation under the effect of mechanical stress, then a rupture, when the mechanical stresses exceed a certain intensity.
- the fusible elements absorb the energy of a shock first by plastic deformation then by rupture. Because the fusible elements plastically deform and then break sequentially, when the device has been shocked sufficient to deform and possibly break a first only part of the fusible elements, a second part elements remains functionally intact. Thanks to the means retainer, which holds a portion of cable inside of the remaining part of the envelope, this remaining part can still absorb a shock corresponding to the number elements remaining intact. At the end of the deformation and rupture of the envelope, the cable is completely free and works according to its characteristics clean.
- the envelope of the absorption device of shock is able to accommodate the portion of cable, which transmits the tensile forces exerted on the cable, shaped like a loop or loop, and has at least one opening through which the two strands of the cable extending the portion shaped like a loop or loop can pass.
- the fuse element bordering the opening first undergoes a deformation. Then deformation, followed by rupture, propagates from element to element element.
- the fusible elements are stackable rings, the dimensions are such that they let in their opening the above-mentioned portion of cable shaped as a handle, and the envelope consists of a stack of these rings stackable, joined together by a holding means stacking.
- the rings can be discs of various shapes.
- the stacking rings can be circular. They may also have an elliptical shape.
- the shape of rings may vary depending on their position in stacking; in particular, the rings of the part central stack can be circular while the rings located at one or both ends can have an elliptical shape to spare the cable.
- the rings can have the same rigidity throughout stacking, stiffness can also vary over stacking, either by choosing the dimensions of the rings either by a choice of the nature of the materials. In particular, the rings intended to break last may be more resistant to favor the passage of the behavior of the cable + behavior absorber assembly cable mechanics alone.
- these rings can be washers of metal welded together by means of at least one bead of solder which maintains their stacking. he is also possible to place the stack of rings in a sheath common, such as a molded or threaded plastic tube on the rings, or the like.
- the dimensions of the rings are c so that under the effect of a pull on the cable, an element of the envelope begins to deform before that the previous element requested before it, be totally broken.
- This choice of material and dimensions avoids the appearance of pulsed forces or shocks, or at least decreases their amplitude.
- a means of restraint particularly simple to carry out consists of an axis whose the length is greater than the largest dimension inner rings. This axis is slid inside the top of the loop or loop protruding from the end of the stack opposite to that through which the two strands exit.
- a such an axis can be generally cylindrical and have two recesses shaped so as to come into contact and fit against two portions of the ring surface constituting one of the ends of the stack.
- the axis can present fixing means making it possible to fix it to the cable and / or ring constituting the end of the device where the cable loop or loop protrudes.
- This ring can present corresponding recesses or holes or lugs.
- Figure 1 shows the casing (1) of a device shock absorption, consisting of a stack of washers 2, 3.
- the washers 2 located in the middle of the stack are circular, while the washers or end discs 3 are slightly elliptical in shape.
- the washers are welded together by two beads of solder, one of which, 4, is visible in Figure 1, the second being substantially diametrically opposite to it.
- a portion of a cable twisted metal C is shaped so as to form a handle, whose apex 5, protrudes from the lower end of stacking, while the two strands 6 and 7 extending the handle towards the two ends of the cable, protrude both by the upper end of the stack.
- Axis 13 arranged across the last washer blocks the top 5 handle relative to the stack and prevents the cable from escape. The ends of the axis 13, which rest on the last washer, are thinned and welded by 2 points to this washer.
- This axis, 12 of generally cylindrical shape, has two plates 8 and 9, to limit the deformation of the end washer and rests on the last washer by these two dishes 8 and 9 as shown in Figure 4.
- This axis is also crossed by two holes 10 and 11. These holes allow to ensure, by the use of means not depicted, such as knotted metal wires, maintaining from the position of the axis 12 in contact with the top of the handle formed by the cable, even if the brake is violently shaken a storm or by a violent pull on one end of the cable.
- the diameter of the axis 12 is approximately half the outside diameter of the washers.
- Figure 2 shows a section of a washer, in illustrating its geometric parameters, namely the length of the washer L in the direction of its axis, the thickness of the washer E and the outside diameter of the washer D.
- the stiffness of a washer is proportional to its thickness E, and the rigidity of the absorption device depends mainly the thickness E of the washers, for a given material.
- the rigidity of the device is also proportional to the modulus of elasticity of the material.
- Steel 37-2 proved to be an advantageous material, neither too rigid, which which would cause an immediate rupture under the effect of a stress without prior plastic deformation, nor too much flexible, which would lead to deformation and destruction almost too many washers.
- the length L of the washers is important with regard to relates to the overall operation of the device. If the washers are long, successive shocks appear when the washers break one after the other. Yes the washers are short, they tend to pass the one over the other during the deformation phenomenon.
- the length of the washers is preferably between 5 and 12 mm. The best results are obtained with a length of 7 mm, regardless of the thickness E of the washer. However, the force required during operation of the device, i.e. the deformation and upon successive rupture of the washers, is not very dependent the length L of the washers.
- Example 1 Procedure for destroying a shock absorber
- the test is carried out on a stack of 65 washers of 7 mm in length, 70 mm in diameter and 5 mm thick.
- the photo in Figure 5 shows the device intact, at the beginning of the test.
- the two cable strands are slightly stretched.
- the tensile force plates the axis located at the top of the photo, surrounded by the top of the handle formed by the cable, against the upper washer.
- the washers close to the axis are oval, the major axis is located in the median plane of the top of the cable loop.
- the photo in Figure 6 shows the start of the destruction of the device: the washer # 1 is already broken, washers nos 2 and 3 are strongly deformed, the washers 4 and 5 start to deform, the others washers are still in their original condition.
- Photo 7 shows the device in the middle phase of the test: in the bottom of the photo we see many broken washers, the three washers at the bottom of the remaining part of the device are being deformed. The washers located above are not yet distorted.
- the photo in figure 8 shows a phase of the test near the end, i.e. the four last washers just before breaking.
- Example 2 Influence of the thickness of the washers on the energy absorbed
- Figure 9 shows three A / F diagrams, elongation of the cable / tensile force applied, for three stacks of washers in Ac 37-2 of the same total length, 750 mm, with the same outside diameter, 70 mm, each washer having an individual length of 7 mm.
- the thickness of each washer is 6 mm, 5 mm, and 4 mm respectively.
- Table 1 summarizes the results of tests carried out with two different steels and different washers dimensions. The table illustrates the influence of the thickness and the length of the washers on the behavior of the device being destroyed.
- Tests show that the cable is very thin marked after initial operation of the device energy absorption; it therefore remains functional and usable. Once the device has worked, the cable stays tense and we still have all our own resistance to perform the function for which it was intended.
- this shock absorption device is extremely simple to realize and very effective in dissipating an amount of energy important.
- a judicious choice of dimensions allows adapt it to the most varied uses.
- the device can absorb the kinetic energy of stones falling into the net and the cable continues to retain all of the masses.
