Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of fueling pipe manufacturing, and particularly relates to a medium transmission hose and a medium transmission hose. BACKGROUND

[0002] The fueling position of an airplane is far away from the fueling control equipment, and in the actual operation process, the operation personnel at two positions need to frequently communicate to confirm operation information, starting and stopping operation time, etc., which greatly limits the operation efficiency. At present, when the fueling operation is completed, the hose docking device is full of oil, and the hose is too heavy during the recovery process, which requires a large number of operation support personnel, has high labor intensity, and seriously affects the operation efficiency. Therefore, in order to realize efficient fueling support of an airplane, it is urgent to provide a light-weight hose capable of realizing signal transmission to support the on-site support and light-weight recovery during the fueling process of an airplane.

[0003] The light-weight hose can be lightened from the aspects of the hose body itself and the removal of residual oil in the hose. At present, the available collapsible rubber hose basically meets the light-weight requirement of the hose. The signal transmission of the hose can be realized by embedding a signal line in the hose wall or by penetrating a signal line in the inner cavity of the hose. These two signal transmission methods have been applied to non-collapsible rubber hoses. However, considering the application in collapsible rubber hoses, for the embedding method, the collapsible hose wall needs to be continuously compressed and expanded, and the strength of the signal line and the rubber hose is difficult to be unified, which can easily cause damage to the rubber or breakage of the signal line, thereby seriously affecting the service life of the hose. For the method of penetrating a signal line in the inner cavity of the hose, after the residual oil in the hose is pumped out, the part of the collapsible hose wrapping the signal line will protrude obviously, which becomes a relatively weak point of the hose structure, seriously affecting the service life of the hose. Moreover, the position of the signal line relative to the collapsible hose cannot be controlled every time, and the local reinforcement cannot be achieved, SUMMARY

[0022] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the protection scope of the present application.

[0023] The aircraft oil filling position is far away from the oil control equipment, and in the actual operation process, the operation personnel at two positions need to frequently communicate and confirm operation information, starting and stopping operation time, etc., which greatly limits the operation efficiency. At present, when the oil operation is completed, the hose docking device is full of oil, and the hose is too heavy during the recovery process. There are problems such as large demand for operation support personnel, high labor intensity, and serious impact on operation efficiency. Therefore, in order to realize efficient aircraft refueling support, it is urgent to provide a light-weight hose capable of signal transmission to support aircraft refueling and light-weight recovery.

[0024] The hose lightening can be started from the lightening of the hose body itself and the removal of the residual oil in the hose. At present, the available collapsible rubber hose basically meets the lightening requirement of the hose. The signal transmission mode of the hose includes embedding a signal line in the hose wall and passing a signal line in the inner cavity of the hose. These two signal transmission modes have been applied in non-collapsible rubber hoses. However, considering the application in collapsible rubber hoses, for the embedded signal line mode, the collapsible hose wall needs to be continuously compressed and expanded, and the strength of the signal line and the rubber hose is difficult to be unified, which easily causes damage to the rubber or breakage of the signal line, seriously affecting the service life of the hose. For the mode of passing a signal line in the inner cavity of the hose, after the residual oil in the hose is pumped out, the part of the collapsible hose wrapping the signal line will protrude obviously, becoming a relatively weak point of the hose structure, seriously affecting the service life of the hose, and since the position of the signal line relative to the collapsible hose is uncontrollable each time, the local reinforcement is impossible,

[0025] The embodiment of the present application provides a manufacturing process of a medium transmission hose, which can prolong the service life of the hose and reduce the risk of breakage of the signal line.

[0026] The following will be described with reference to the drawings of the specification Figures 1-4 The medium transmission hose will be described in detail.

[0027] Figure 2 The structure diagram of the expanded state of the hose, at this time, the hose is in the oil conveying condition, bears positive pressure, and the overall shape of the hose is approximately circular. The pipe wall of the dumbbell and the free curved part is expanded, and the signal transmission line bundle 4 embedded in the middle part of the pipe wall will move position with the pipe wall, but the deformation of the pipe wall at this position is small.

[0028] Figure 3 The structure diagram of the soft tube in the flat state, at this time, the soft tube is in the oil recovery pipe, and the soft tube bears negative pressure, the overall shape of the soft tube is dumbbell-shaped, the pipe wall of the dumbbell-shaped part at both ends is circular, the free curved part is flattened to the state that the inner wall of the soft tube is nearly in contact, and the middle part still maintains the state of being approximately circular.

[0029] The application provides a manufacturing process of a medium transmission soft tube, and the manufacturing process comprises the following steps: manufacturing a tubular inner liner 1; inserting a circular fixed mandrel into the inner liner 1, the outer surface of the fixed mandrel is attached to the inner surface of the inner liner 1; wrapping a reinforcing layer 2 on the outer surface of the inner liner 1; laying a signal transmission wire bundle 4 on the outer surface of the reinforcing layer 2; wrapping a protective layer 5 on the outer surface of the signal transmission wire bundle 4; vulcanizing the tubular structure formed by the inner liner 1, the reinforcing layer 2, the signal transmission wire bundle 4 and the protective layer 5; separating the fixed mandrel from the inner liner 1; inserting a shaping mandrel into the inner liner 1; and molding and shaping the inner liner 1, the reinforcing layer 2, the signal transmission wire bundle 4 and the protective layer 5.

[0030] Specifically, the manufacturing process of the medium transmission soft tube comprises the following steps: manufacturing a tubular inner liner 1; inserting a circular fixed mandrel into the inner liner 1, the outer surface of the fixed mandrel is attached to the inner surface of the inner liner 1, and the fixed mandrel is used to support the inner liner 1; wrapping a reinforcing layer on the outer surface of the inner liner 1, so that the part of the soft tube in which the signal transmission wire bundle is embedded can still maintain the structural form when the soft tube bears negative pressure, and the signal transmission wire bundle 4 is prevented from being bent and broken due to the negative pressure borne by the soft tube; laying a signal transmission wire bundle 4 on the outer surface of the reinforcing layer 2, so as to realize stable and reliable signal transmission; wrapping a protective layer 5 on the outer surface of the signal transmission wire bundle 4, so that the entire medium transmission soft tube has the functions of wear resistance, outdoor exposure resistance and petroleum-based fuel resistance; vulcanizing the tubular structure formed by the inner liner 1, the reinforcing layer 2, the signal transmission wire bundle 4 and the protective layer 5, so as to improve the strength and elasticity of the medium transmission soft tube; separating the fixed mandrel from the inner liner 1, inserting a shaping mandrel into the inner liner 1, and molding and shaping the inner liner 1, the reinforcing layer 2, the signal transmission wire bundle 4 and the protective layer 5, so that the medium transmission soft tube has the shape of the inserted shaping mandrel, the medium transmission soft tube can expand to realize oil delivery when bearing positive pressure, and the medium transmission soft tube can maintain the basic shape of the soft tube when bearing negative pressure, so that the medium transmission soft tube can maintain a stable state in each working state.

[0031] Further, the vulcanization of the tubular structure formed by the inner liner 1, the reinforcing layer 2, the signal transmission wire bundle 4 and the protective layer 5 has the following advantages: improving strength and elasticity, the vulcanization process can change the molecular structure of rubber from linear to three-dimensional network structure, which enhances the interaction between molecular chains, thereby significantly improving the strength and elasticity of rubber. When the vulcanized rubber is subjected to external force, it can better resist deformation and breakage. Improve wear resistance and swelling resistance, the crosslinking bonds formed during vulcanization limit the movement of rubber molecules, reducing the wear and swelling of rubber under friction and solvent action, so that the vulcanized rubber can maintain good performance stability during long-term use. Improve heat resistance and chemical stability, the formation of crosslinking bonds limits the thermal motion of rubber molecular chains, improving the heat resistance of rubber. At the same time, the crosslinking reaction reduces the groups or atoms with high chemical activity, making it difficult for aging reactions to occur, thereby improving the chemical stability of the rubber.

[0032] Optionally, the medium transmission hose is a refueling hose for refueling an aircraft.

[0033] In some optional embodiments, the step of laying the signal transmission wire bundle 4 on the outer surface of the reinforcing layer 2 includes laying at least two signal transmission wire bundles 4 on the outer surface of the reinforcing layer 2, the signal transmission wire bundles 4 being arranged circumferentially on the surface of the inner liner 1, and any two signal transmission wire bundles 4 being symmetrical about the center line of the inner liner 1. The signal transmission wire bundle 4 includes a plurality of signal transmission wires 41, and any two signal transmission wires 41 have a predetermined distance therebetween, and each signal transmission wire 41 is curved in a serpentine shape.

[0034] Further, any signal transmission wire bundle 4 is curved in a serpentine shape to prevent the signal transmission wire bundle 4 from being pulled off due to length changes in the working state of the hose. Two signal transmission wire bundles 4 are laid on the outer surface of the reinforcing layer 2, and the two signal transmission wire bundles 4 are symmetrical about the center line of the inner liner 1. The intermediate circularly curved portion of the medium transmission hose is reinforced by the reinforcing layer 2 to ensure that the portion of the hose in which the signal transmission wire bundle 4 is embedded can still maintain its structural form when subjected to negative pressure, preventing the signal transmission wire bundle 4 from being bent and causing breakage due to the hose being subjected to negative pressure. As shown in Figure 1 The signal transmission wire bundle 4 is uniformly arranged in a ring shape in the wall of the intermediate circular medium transmission hose, the signal transmission wire bundle 4 is arranged between the reinforcing layer 2 and the protective layer 5, and the signal transmission wire bundle 4 extends along the length direction of the medium transmission hose and is arranged in an S-shaped serpentine shape to prevent the signal transmission wire bundle 4 from being pulled off due to length changes in the working state of the hose. When oil is delivered outward through the medium transmission hose, the medium transmission hose is subjected to positive pressure, the free flexing portion of the medium transmission hose is stretched, the entire medium transmission hose expands to a circular shape, and the expanded state of the hose is shown in Figure 2 When the remaining oil in the medium transmission hose is pumped out, the medium transmission hose is subjected to negative pressure, the free flexing portion of the hose is flattened, and the hose is basically in the shape of a dumbbell, as shown inFigure 3 as shown.

[0035] As shown, Figure 1 Figure 1 The figure is a structural diagram of the initial state of the medium transmission hose. At this time, the medium transmission hose is not under pressure, and the overall shape of the medium transmission hose is dumbbell-shaped. The pipe walls of the dumbbell-shaped parts at both ends and the middle part are circular, and the pipe walls of the rest are in a free curved state. The medium transmission hose is locally reinforced by the densely woven fabric reinforcement layer 2 at the circular pipe wall in the middle. On the basis of maintaining the basic shape of the initial state and the collapsed state of this part, grooves are arranged on the outer surface of the fabric reinforcement layer 2. The grooves are used to embed the signal transmission line 41, fix the signal transmission line 41, and the depth of the grooves matches the diameter of the signal transmission line 41 to ensure that the protective layer 5 of the medium transmission hose after forming is uniform in the circumferential direction and does not appear to be convex due to the embedded signal transmission line 41.

[0036] Figure 2 The figure is a structural diagram of the inflated state of the medium transmission hose. At this time, the medium transmission hose is in the oil delivery working condition and bears positive pressure. The overall shape of the medium transmission hose is circular, the pipe walls of the dumbbell and the free curved part are expanded, and the signal transmission line 41 embedded in the pipe wall of the middle part will move position with the pipe wall, but the deformation of the pipe wall at this position is small.

[0037] Figure 3 The figure is a structural diagram of the collapsed state of the medium transmission hose. At this time, the medium transmission hose is in the oil recovery working condition and bears negative pressure. The overall shape of the medium transmission hose is dumbbell-shaped, the pipe walls of the dumbbell-shaped parts at both ends are circular, the free curved part is collapsed to a state where the inner walls of the medium transmission hose are almost in contact, and the middle part remains in a circular state.

[0039] ​Specifically, the medium transmission hose comprises an inner liner layer 1, a reinforcing layer 2, a signal transmission wire bundle 4 and a protective layer 5 arranged in layers from inside to outside, and the manufacturing process of the medium transmission hose comprises the following steps: manufacturing a tubular inner liner layer 1; inserting a circular fixed mandrel into the inner liner layer 1, the outer surface of the fixed mandrel being in contact with the inner surface of the inner liner layer 1, the fixed mandrel being used to support the inner liner layer 1; wrapping the reinforcing layer 2 around the outer surface of the inner liner layer 1 to ensure that the part of the hose in which the signal transmission wire 41 is embedded can still maintain its structural form when the hose is subjected to negative pressure, preventing the signal transmission wire bundle 4 from being bent and broken due to the negative pressure of the hose, and the mold setting makes the medium transmission hose have the shape of the setting mandrel, so that the medium transmission hose can not only expand to realize oil delivery when subjected to positive pressure, but also maintain the basic shape of the hose when subjected to negative pressure, so that the structure can maintain a stable state in each working state. The signal transmission wire bundle 4 is laid on the outer surface of the reinforcing layer 2 to realize stable and reliable signal transmission, the fixed mandrel is detached from the inside of the inner liner layer 1, a setting mandrel is inserted into the inside of the inner liner layer 1 to realize stable and reliable signal transmission, the protective layer 5 is wrapped around the outer surface of the signal transmission wire bundle 4, and the protective layer 5 makes the entire medium transmission hose have the functions of wear resistance, outdoor exposure resistance and petroleum-based fuel resistance. The outer surface of the protective layer 5 is subjected to vulcanization treatment to improve the strength and elasticity.

[0040] Further, the medium transmission hose is mold set in a dumbbell shape, the dumbbell-shaped hose structure can not only expand to realize oil delivery when subjected to positive pressure, but also maintain the basic shape of the hose when subjected to negative pressure, without obvious bending angle, and is suitable for repeated oil recovery operation conditions. And by arranging grooves in the reinforcing layer 2 and arranging signal transmission wires 41 in the grooves, stable and reliable signal transmission is realized by the structure which can maintain a stable state in each working state. The inner liner layer 1 and the protective layer 5 are both made of rubber material, and such a rubber hose structure can take into account signal transmission and oil recovery, effectively support the aircraft refueling process, and improve the efficiency of aircraft refueling support.

[0041] In some optional embodiments, the materials of the inner liner layer 1 and the protective layer 5 are rubber.

[0042] Specifically, the protective layer 5 is made of rubber material, and such a rubber hose structure can take into account signal transmission and oil recovery, effectively support the aircraft refueling process, and improve the efficiency of aircraft refueling support.

When the vulcanized rubber is subjected to external force, it can better resist deformation and rupture. Improving wear resistance and swelling resistance, the cross-linking bonds formed during vulcanization limit the movement of rubber molecules, reducing the wear and swelling of rubber under the action of friction and solvents, so that the vulcanized rubber can maintain good performance stability during long-term use. Improving heat resistance and chemical stability, the formation of cross-linking bonds limits the thermal motion of rubber molecular chains, improving the heat resistance of rubber. At the same time, the cross-linking reaction reduces the groups or atoms with high chemical activity, making it difficult for aging reactions to occur, thereby improving the chemical stability of the rubber.
