Description

KIT WITH EQUIPMENT OR EMERGENCY HOSE REPAIR FIELD OF THE INVENTION [001] The present invention discloses a kit with apparatus for emergency hose connection or repair, in addition to a method for emergency hose connection or repair, preferably those that operate under high demands . Said apparatus allows the union of the ends of the hoses, allowing a quick emergency repair and its subsequent use, through the union of the ends of the hoses. The present invention is in the field of hydraulic engineering.

BACKGROUND OF THE INVENTION [002] Flexible hoses are used for the most diverse industrial, residential or commercial applications, in order to conduct liquids and gases in straight or sinuous paths. The differences between the applications are basically in the type of fluid to be transported, which can be: solids; low or high density liquids; vapors; among others, that travel inside the hose under certain temperatures and operating pressures. There is also some specificity regarding the external environment, which can sometimes be aggressive to the hose, with variations in temperature, acidity, salinity, mechanical impacts, bad weather, among others.

[003] Regarding applications and types of hoses, those intended for domestic use are some of the simplest and easiest to find, and these are commonly used to conduct water under moderate pressures.

[004] A second application of hoses, which can also be commonly found, makes reference to those used in the conduction of compressed air, where the high internal pressure is a relevant factor, in such a way that the structural resistance of the hose becomes a requirement fundamental to its operational security.

[005] A third application refers to the hoses used to conduct fluids under very high pressures, resulting in a pressure exerted on the inner surface of the hose much higher than the pressure exerted on the external surface of the hose. In general, this condition occurs for hoses that conduct hydraulic fluids, which are ultimately used as a form of energy

2/16 (hydraulic), either for moving engines or for transmitting power in hydraulic actuators.

[006] For this last type of hose there is the possibility that fluids are carried under very high or very low temperatures, hydraulic oils and, even toxic or carcinogenic gases, in which any leak caused by a rupture of a section of the hose, can represent a serious impact and serious consequences for the environment or the health of people in the vicinity of the spill site.

[007] Due to the risk caused by contact with these fluids, at the slightest sign of leakage, it is necessary to interrupt its flow, in order to carry out the necessary repairs and resume the system's operating condition in the shortest possible time, in order to avoid losses arising this interruption of supply of the transported fluid.

[008] In the case of hoses capable of withstanding specific and extreme operating conditions, as mentioned in the last application above, the cost of manufacturing and, consequently, selling these hoses is quite high. In addition, the variety of types, lengths, terminals and hose gauges possible on the same machine or set of equipment makes stocking spare parts extremely expensive and unviable. For this reason, inventories are usually minimized, which makes it difficult to change them outside their expected time of use, when there is a small break in just a short stretch. Thus, it is necessary to provide solutions to optimize the useful life of this type of hoses, providing an emergency repair of the defective section, ensuring the tightness and resistance to the operational conditions of the hose.

[009] In the patent scope, some documents related to this field of application were found, which will be described below.

[010] US 5,178,421 describes an apparatus for repairing hoses by eliminating the defective section and subsequent installation of the apparatus, which may be installed directly in the fluid source, by means of a screw connection, when the defective hose section is at the end of it. As for the

Petition 870190042396, of 05/06/2019, p. 13/32

3/16 defective section is arranged in half the length of the hose, the use of two devices associated with each other is provided. Said apparatus consists of a flange provided with a projection capable of housing inside a hose and a split clamp capable of being mounted under the external surface of the hose, in the region where the projection occupies the interior of the same hose section . The split clamp comprises notched ribs on its internal surface, in order to check the locking on the adapter when it is separated from the flexible hose and also to concentrate the clamping force of the clamp on the hose.

[011] The present invention differs from this document in that US 5,178,421 describes an apparatus provided with a conventional flange for fixing flexible hoses, comprising a split clamp to lock the hose on the flange, but does not describe an intermediate locking element comprising preferably an independent cylindrical body, intermediating the flange and the locking element, according to the present invention. In addition, said apparatus is intended only for use in conventional hoses, operating with water at a weighted pressure, not guaranteeing a tight condition for transporting gases or fluids in general under a high pressure, according to the object of the present invention.

[012] US 4,478,434 describes a device capable of coupling two ends of tubes, the device being defined by a segment of tube provided with a longitudinal slit that extends along its entire length, giving an opening or closing condition of the pipe segment, allowing the opening and closing of the cross section of this segment and the consequent variation of its diameter. The external surface of the said pipe segment comprises two curved L-shaped fins, facing the slot and cooperatively associated by means of a screw, which is able to regulate the opening and closing of the cross section, enabling fixation in the assembly of the device in the tubes where it will be installed. Additionally, it is envisaged to use a pair of straps aligned with the connected ends of the pipe segment to the connected pipes. The equipment also has a seal on at least one of the crevice boundary surfaces.

Petition 870190042396, of 05/06/2019, p. 14/32

4/16 [013] The present invention differs from this document, since the solution proposed by US 4,478,434 requires assembly with a high number of components and of great difficulty to allow an ideal fit between the device and the tubes to be connected. In addition, it is imperative that the tubes to be connected are provided with the same diameter, so that the device can be equally solidary to both, and it is also necessary to use straps to ensure the tightness of the connections of the described device, preventing its use in critical conditions and making it difficult to install, requiring a long maintenance time. In addition, also, the limitation of operating pressures, and consequently the types of hoses. All of these disadvantages are overcome in the present invention.

[014] WO 2006/066328 describes a method and apparatus for containing a leak in a flexible hose by installing sealing rings on the external surface of the hose, close to the leak region. Cooperatively with the aforementioned sealing rings and with the hose, a pair of complementary elements are assembled, the first element having an internal cylindrical surface with an arc angle greater than 180 ° and a second element having an internal cylindrical surface which has an arc of less than 180 °, the first and second elements being associated by means of screws. In the internal surface of said complementary elements, grooves are arranged to accommodate said sealing rings, keeping them pressed against the external surface of the hose and ensuring the tightness of the defective region.

[015] The present invention differs from this document in that the solution proposed in WO 2006/066328 makes reference to a solution in which it is necessary to have access to at least one free end of the hose to allow the assembly of the sealing rings. Additionally, the defective region of the hose remains in the hose, allowing the crack / tear to extend over time, and may extend outside the containment area provided by the apparatus. Furthermore, the solution proposed in document W02006 / 066328 requires continuous maintenance with regard to the life of the sealing rings, making inefficient and unreliable the

Petition 870190042396, of 05/06/2019, p. 15/32

5/16 hose tightness. In addition, it is a device for repairing hoses with limited applications and pressures. All of these disadvantages are overcome in the present invention.

[016] WO 2011/143732 describes a separator for coupling to hoses that transmit high pressure fluids in the form of gas. The coupling consists of four parts. The first is attached to the first hose and the second part is attached to the second hose. The first part includes a thread that is attached to the nut thread in a third element by an insertion and turning movement. The axial forces generated by fluid flowing through the coupling must generate enough pressure to overcome the torsional forces by holding the first and third elements together. The third element is attached by a fourth element that has clockwise movement, but does not allow movement in an anti-clockwise direction by a one-way clutch that is located between the third and fourth element. The document describes means to create a lateral movement of the fluid together with the coupling to minimize the posterior axial pressure which can lead to uncoupling.

[017] The present invention differs from this document, since the solution proposed in WO 2011/143732 makes use of a high number of components, representing a high level of complexity for assembling it, in addition to a high manufacturing cost to manufacture the even, making its application unfeasible in several situations because it represents a high cost and a long assembly time, representing damage to processes that depend on the supply of fluid driven by the hose. All of these disadvantages are overcome in the present invention.

[018] From what can be inferred from the researched literature, no documents were found anticipating or suggesting the teachings of the present invention, so that the solution proposed here has novelty and inventive activity in view of the state of the art. SUMMARY OF THE INVENTION [019] The present invention discloses a kit comprising an apparatus for emergency coupling or repair of hoses being used, preferably, in hoses that operate under high demands.

DETAILED DESCRIPTION OF THE INVENTION [035] The present invention makes use of an apparatus for emergency repair or hose connection, said connection being made from the junction of at least two free ends of at least one hose, in a watertight and easy manner. and quick installation.

[036] The object of the present invention refers to a hose trimmer or hose trimmer, for preferential use, but not limiting, in hoses that operate under high demands, such as: hoses that carry hydraulic oil under high pressures and / or temperatures; hoses that are exposed to environments under high / low temperatures; high / low pressures / bad weather; different levels of ph; conduction of contagious fluids; among several other conditions that can cause its premature deterioration, resulting in cracks, holes or small leak holes.

Petition 870190042396, of 05/06/2019, p. 20/32

10/16 [037] When a hose that is subjected to uses, such as those mentioned above, breaks or starts to leak, it is imperative that its replacement be provided as soon as possible.

[038] Coupled with the urgency to replace such hoses, there is a health risk that the leaking fluid may cause to individuals close to the leak site, or even result in loss of productivity, due to the interruption or reduction of capacity of a dependent process. of the leaking fluid.

[039] However, the costs of hoses, such as those that need to withstand high demands, are quite high, especially due to the fact that they require special manufacturing processes, noble materials and, often, are manufactured in small quantities , serving only order requests.

[040] For the purpose of solving these problems, the present invention reveals an apparatus capable of providing emergency hose connection or repair, comprising:

a) at least one flange having a diameter substantially equal to the inside diameter of a hose;

b) at least one locking element comprising at least one intermediate locking element and;

c) fastening means between the locking element and the flange.

HOSES ADAPTED FOR HIGH REQUEST CONDITIONS [041] The present invention has a number of advantages, including the fact that it allows for the quick emergency repair of a damaged hose, followed by its immediate reuse, using an easy-to-assemble apparatus, dispensing special tools, easy to port and can be used in hoses adapted to conditions of high demands, giving a reduced machine downtime.

[042] The present invention understands as hoses adapted for high demands, as hoses carrying fluids, solids, vapors under high / low pressures and temperatures, different pH levels, salinities and densities,

Petition 870190042396, of 05/06/2019, p. 21/32

11/16 without causing damage or posing a risk to equipment and / or operators close to the locations where the hose operates.

FLANGE [043] The flange of the present invention comprises a body, preferably cylindrical, with a shoulder partly thereof, optionally comprising grooves or thread threads on its outer sides. The flange of the present invention will serve as a base for fitting the hose and may contain additional connection and / or fixation elements with the intermediate locking elements and / or with the locking elements, for example, but not restricted to pins.

INTERMEDIATE LOCKING ELEMENT [044] The intermediate locking element of the present invention makes the connection between the hose and the flange and is preferably composed of at least one nut and / or at least one clamp. More preferably, in certain embodiments, one, two, three, four or more intermediate locking elements may be used.

LOCKING ELEMENT [045] The locking element of the present invention acts on the intermediate locking element, preferably assisting in locking it. [046] Preferably, the locking element consists of a cradle comprising a hollow that allows the fitting of a chestnut or part of it. In another preferred embodiment, the locking element is tapered and allows intermediary elements, such as clamps, to be fitted. In yet another preferred configuration, the locking element is tubular and, in addition, it can completely overlap the intermediate element.

FIXING MEANS [047] The fixing means between the flange and the locking element of the present invention comprise any elements capable of conferring the functional union between two or more bodies, additionally also being able to confer resistance capable of withstanding the forces applied to the system, preventing it from collapsing - we can cite as examples of fixation means: nuts,

Petition 870190042396, of 05/06/2019, p. 22/32

12/16 screws, elastic rings, rivets, pins, among others, as well as their combination. In a configuration of the present invention, the fastening means is an additional element that allows the connection between the locking element and the flange. [0047] In another embodiment of the present invention, the fastening means can be an integral part of the locking element and / or the intermediate locking element. [048] The present invention describes a new apparatus capable of joining at least two ends of at least one hose quickly, enabling safe repair and connection, in addition to a method for emergency hose connection and / or repair. [049] [049] The apparatus can be used until a new hose is made and can be installed on site.

[050] This union allows a hose that has ruptured caused, for example, by mechanical wear to be cut completely and reused with the insertion of this device, thus avoiding immediate stops, the need to wait for the manufacture of another hose, the need for stocks large hoses, need to dismantle the machine and / or manufacturing line for repair and for all these reasons a great savings in all aspects.

[051] In order to simplify its application, the device presented here can be installed directly on the hose without the need to peel it. It is enough that the damaged hose is cut in two parts, with its ends correctly paired, and the hose connection device is placed. [052] In addition to the operational advantage of installing the apparatus, both for practicality and portability, there are numerous environmental and occupational advantages that translate into economic advantages for those who apply it.

[053] The device has an emergency application character and can be replaced as soon as it is possible to stop the equipment. In addition, the apparatus respects technical limits, such as curves, proximity to the terminals, tightness, among other factors imposed by each case and operational to ensure safe application. PREFERENTIAL ACHIEVEMENTS - EXAMPLES [054] The apparatus for joining and / or emergency hose repair is preferably used in flexible hoses adapted to extreme conditions.

Petition 870190042396, of 05/06/2019, p. 23/32

13/16 [055] The use of the apparatus preferably follows the following steps:

1. Stop the flow of fluid and analyze the damaged area of the hose;

2. The damaged area is cut transversely, forming two ends in the hose;

3. The ends are joined through the opposite ports of the nozzle;

4. Fit the chestnuts in their corresponding cradles;

5. The pair of chestnuts and cradles closes adjacent to the nozzle ends;

6. A pair or more of screws and a pair or more of nuts securely fix the halves of each of the cradles;

7. The fluid flow is released slowly and continuously.

[056] The examples shown here are intended only to exemplify one of the countless ways of carrying out the invention, however, without limiting its scope. [057] The embodiment of the apparatus illustrated in figure 13 makes reference to a first constructive variation of the apparatus where the flange (1) (nipple) is provided with rectangular teeth and a larger tooth for fitting the cradle (3). The cradles (3) preferably have four holes for the entry of the clamping and fixing screws, a semi-cylindrical gap for fitting the nut / intermediate locking of internal teeth (2) and a tooth to fix it to the flange 1 (nipple) and avoid slipping between the hose (4) and the flange (1) (nipple). The chestnut / intermediate locking of internal teeth (2) has five sharp teeth, three of which are larger and two smaller. The larger ones have the function of fixing the hose (4) and the smaller ones to prevent it from breaking if bent at the exit of the nut / intermediate locking of internal teeth (2).

[058] The implementation of the apparatus illustrated in figure 14 has some changes in relation to the embodiment illustrated in figure 13. In the cradle (3), these modifications are: decrease from four to two tightening screws, incorporation of the flange fitting gap ( 1) (nipple), addition of grooves corresponding to the number of wefts that fit the nut / intermediate locking of internal teeth (2), screw for removal of the nut / intermediate locking of internal teeth (2) and change in shape to reduce weight . The brown / intermediate locking of internal teeth (2) in figure 14 comprises positioning flaps that indicate the amount of

Petition 870190042396, of 05/06/2019, p. 24/32

14/16 wefts of the corresponding hose (4). These positioning shoulders, in turn, fit into the grooves of the cradle (3). The flange (1) (nipple) of this model and the clamping shape are similar to the previous one.

[059] The implementation of the apparatus illustrated in figure 15 has some changes in relation to the embodiment illustrated in figure 14: the cradle (3) for hoses (4) of small gauge and few threads had its manufacturing material modified to a polymer, aiming decreased weight of the set. The cradles (3) also comprise a more simplified geometry, not including the flange fitting (1) (nipple) and the grooves, leaving only the central span and screw holes (5). The brown interlocking of internal teeth (2) of this concept is able to concentrate all the applicable functions, from the role of holding the hose (4), to the role of holding the flange (1) (nipple) and the interlocking of teeth internal (2). For this purpose, it comprises a flange fitting slot (1) (nipple) and two external shoulders that hold the cradle (3), forming the system junction around it. The flange (1) (nipple) of this version has been replaced with the special designed for the industrial standard.

[060] The embodiment of the apparatus illustrated in figure 16 comprises a cradle, preferably made of polymeric material, provided with greater width for better tightening of the screws (5). The brown teeth / intermediate locking of internal teeth (2) were modified for better penetration into the hose (4).

[061] The implementation of the apparatus illustrated in figure 17 aims at the use of nuts / intermediate locking of internal teeth (2) acting as clamps so that, with the tightening in the longitudinal direction of the locking element (3), the nuts / intermediate locking of internal teeth (2) are pressed against the hose (4), generating the fixation and locking of the hose (4) with the flange (1) (nipple). This system uses a central threaded flange (1) (nipple) where the cradle (3), also threaded, is fixed.

[062] The embodiment of the apparatus illustrated in figure 18 comprises a simplified chestnut / interlocking scheme of internal teeth (2), where the chestnuts for both hoses are constituted in a single piece, resulting in

Petition 870190042396, of 05/06/2019, p. 25/32

15/16 in decreasing the number of nuts / intermediate locking of internal teeth (2) to, preferably, three pieces.

[063] In this embodiment, the tightening is done by two longitudinal screws that, due to the reduction of the distance inherent to the tightening of the screw (5) and threads, move the locking elements (3) against each other, acting on the intermediate internal teeth locking elements (2).

[064] The locking element (3) comprises a tapered inner surface and the intermediate locking element (2) has a tapered outer surface, being able to act cooperatively with the inner tapered surface of the locking element (3), generating a resultant force facing the central direction of flange 1 (nipple), acting on the intermediate elements of internal teeth locking (2), resulting in the fixation of the hose (4) to the flange (1) (nipple). In a preferred embodiment, the flange (1) (nipple) also comprises the guide region (7) of the intermediate locking element for internal teeth (2), preferably defined by radial pins being cooperatively associated with radial openings in the intermediate locking elements (2).

[065] The guide pins (7) direct the intermediate locking element of internal teeth (2), towards the flange (1) (nipple), when it is activated by the locking element (3) and, also, guarantee that the intermediate internal teeth locking elements (2) are kept in their longitudinal position of operation and / or assembly of the apparatus.

[066] The embodiment of the device illustrated in figure 19, thus the embodiment illustrated in figure 18, comprises the intermediate element for locking internal teeth (2) provided with a conical external surface. The locking element (3), however, being provided with a substantially cylindrical internal surface and an external surface comprising thread threads capable of operating cooperatively with the fixing means (5).

[067] The fixing means (5) are defined by substantially hollow crowns, comprising an internal surface with threaded threads and a surface

Petition 870190042396, of 05/06/2019, p. 26/32

16/16 external equipped with a geometry capable of allowing them to be tightened with the aid of a suitable tool. Such geometry, preferably being hexagonal.

[068] Depending on the tightening of the crowns (5), the locking element (3) is superimposed on the intermediate locking elements with internal teeth (2), causing them to act on the hose 4 fixing it on the flange ( 1) (nipple).

[069] In this embodiment, the intermediate locking elements (2) comprise a guide region (7) on its internal surface, capable of operating cooperatively with a guide region (7) of the flange (1) (nipple), ensuring the longitudinal positioning of the intermediate locking elements of internal teeth (2). Such a guide region (7) is preferably defined by at least one shoulder on the internal surface of the locking element (2) capable of operating cooperatively with at least one depression on the external surface of the flange (1) (nipple).

[070] Figure 20 illustrates an embodiment in which the device is used directly on a terminal (6) of a valve, reservoir, fluid transport route, instead of being used at the junction of two hose ends.

[071] It should be noted that such use is possible with any of the variations described in this report, since all embodiments refer to a symmetrical device, which comprises the same principle of operation for fixing the two ends of the defective hose. Therefore, the present invention can be used in the connection of two hose ends, or in the connection of a hose end with any terminal, comprising a nipple capable of being associated with it.

[072] Those skilled in the art will value the knowledge presented here and will be able to reproduce the invention in the modalities presented and in other variants, covered by the scope of the attached claims.
