Description

  The present invention relates to a method of laying a hose.

  When laying a hose, the method of carrying a hose on a trolley and conveying is known (for example, patent document 1).

Patent No. 5964368

  However, it has been difficult to use a truck to transport the hose in an ungrounded area. Moreover, when a level | step difference, a steep gradient, etc. exist in the conveyance path | route of a hose, these level | step differences, a gradient, etc. might make utilization of a trolley difficult.

  In this invention, it aims at providing the laying method of the hose which can lay a hose more certainly.

  In order to solve the problems described above and achieve the object, a method of laying a hose according to the present invention is a method of laying a hose for laying a flexible hose, and a sleeve through which the hose is inserted inside The unmanned aerial vehicle lifts into the air and transports the hose together with the sleeve to the laying position.

  As a desirable mode of the present invention, the sleeve has two half cylinder parts and a connecting part which connects the two half cylinder parts so as to be rotatable relative to each other about an axis extending in the insertion direction.

  As a desirable mode of the present invention, the sleeve is lifted to the unmanned aerial vehicle via a string-like member connected to the unmanned aerial vehicle at one end side, and each of the two half-cylinders is provided on the outer peripheral surface side And the attaching part to which the other end side of the said string-like member is attached.

  According to the present invention, the hose can be laid more reliably.

FIG. 3 is a perspective view showing an example of the form of a sleeve. FIG. 4 is a perspective view showing an example of the form of a sleeve. FIG. 5 is a view showing a case where the sleeves of FIGS. 3 and 4 are opened. FIG. 6 is a perspective view showing an example in the case of carrying by a drone through a hose inside a sleeve. FIG. 7 is a perspective view showing an example in the case of carrying by a drone through a hose inside a sleeve. FIG. 8 is a perspective view showing a modified example of the sleeve.

FIG. 11 is a view showing an example in the case of carrying by a drone through a hose inside a sleeve of a modified example.

  Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic view showing an example of the installed hose H. As shown in FIG. FIG. 2 is a schematic view showing an embodiment of a method of laying a hose H according to the present invention. The hose H is flexible and is laid along a hose laying site (for example, a laying site E1 shown in FIG. 1, a laying site E2 shown in FIG. 2 and the like).

  The location of the hose is not always flat. For example, as in the installation site E1 shown in FIG. 1, the installation site of the hose is sloped between the tip end H1 of the hose H and the opposite side thereof (a source of liquid or gas passed through the hose H). May be included. In addition, as in the installation site E2 illustrated in FIG. 2, the installation site of the hose may be an incomplete site. For example, even if it is a place where hose H was laid in the past, it may become an untidy place like laying place E2 by collapse etc. accompanying disasters, such as an earthquake. It is difficult for a worker who lays the hose H to enter a rough ground, especially in a place where a fall has occurred. For this reason, for example, when the hose laid in the past is damaged due to a disaster and it becomes necessary to lay the hose H again, the laying of the hose H may be difficult by the existing method.

  On the other hand, in the method of laying a hose according to the present invention, as shown in FIG. 2, the unmanned airplane D (for example, two unmanned airplanes D1 and D2) lifts the sleeve 10 through which the hose H is inserted. The hose H together with the sleeve 10 is transported to the laying position. Thereby, the hose H can be transported to the installation position regardless of the state of the installation site (for example, the installation site E1, the installation site E2, etc.) of the hose.

  FIG. 2 shows an example in which two unmanned airplanes D1 and D2 suspend the individual sleeves 10 and carry the air while supporting the hose H at two places. When it is not necessary to distinguish two unmanned airplanes D1 and D2, the unmanned airplane D may be described. The number of unmanned airplanes D used for transportation is not limited to two, and may be any number. The number of sleeves 10 corresponds to the number of unmanned airplanes D.

  3 and 4 are perspective views showing an example of the form of the sleeve 10. FIG. 5 is a view showing the case where the sleeve 10 of FIGS. 3 and 4 is opened. FIG. 5 is a view of the sleeve 10 seen along the central axis direction of the sleeve 10. 6 and 7 are perspective views showing an example of the case where the unmanned airplane D is transported through the hose H inside the sleeve 10. As shown in FIG. As illustrated in FIGS. 3 to 7, the sleeve 10 has two half barrels 11 and 12. Moreover, the sleeve 10 has the connection part 13 which mutually connects two semi-cylindrical parts 11 and 12 mutually rotatably centering on the axis | shaft which follows an insertion direction on a division | segmentation surface. The pivoting portion may be provided with a pivoting mechanism such as a hinge connecting the two half-cylinders 11 and 12, for example, or integrally provided with the two half-cylinders 11 and 12 made of resin. It may be a bent portion having flexibility. When the sleeve 10 has a cylindrical shape and the hose H is inserted, the two half-cylinder portions 11 and 12 sandwich a dividing surface that divides the sleeve 10 into two along the insertion direction of the hose H. It opposes (refer FIG. 7). Hereinafter, for example, as shown in FIG. 3 and FIG. 7, the state in which the sleeve 10 is cylindrical may be expressed as “closing”. Moreover, as shown in FIG. 5, the state which the other side of the position connected with the connection part 13 mutually separates may be expressed as "open" among two half-cylinder parts 11 and 12 .

  The sleeve 10 is lifted to the unmanned airplane D via a string-like member (for example, a string 20). One end side of the string-like member is connected to the unmanned airplane D. The other end side of the string-like member is attached to two attachment portions 14 and 15 provided on the outer peripheral surface side of each of the two half-cylinder portions 11 and 12. Specifically, the mounting portion 14 is provided so as to extend from the outer peripheral surface of the half cylindrical portion 11. The mounting portion 14 is positioned substantially opposite to the connecting portion 13 with respect to the central axis of the semicircular arc drawn by the semi-cylindrical portion 11, that is, the central axis of the cylinder when the sleeve 10 takes a cylindrical form. doing. The mounting portion 15 is provided so as to extend from the outer peripheral surface of the half cylindrical portion 12. The mounting portion 15 is positioned substantially opposite to the connecting portion 13 across the central axis of the semicircular arc drawn by the semi-cylindrical portion 12. The two mounting portions 14 and 15 have a plate-like structure facing each other across the dividing surface when the sleeve 10 is closed (see FIGS. 3 and 7).

  More specifically, in the present embodiment, the string 20 is adopted as a string-like member. Further, the mounting portion 14 is provided with a hole 14 a. Further, the mounting portion 15 is provided with a hole 15 a. Further, on the other end side of the cord 20, a hooking portion 21 is provided. The inner diameter of the holes 14a and 15a is such a size that the cord 20 can be inserted and the hooking portion 21 can not be inserted. Although the holes 14a and 15a illustrated in FIGS. 3 to 7 are circular holes, the specific shape of the holes 14a and 15a can be changed as appropriate.

  Next, the method of carrying the hose H using the unmanned airplane D and the sleeve 10 will be illustrated. First, for example, as shown in FIG. 5, the sleeve 10 is opened so that the inner peripheral surface side of the cylinder is on the upper side. The hose H is placed on the sleeve 10 in this state, and the cord 20 is passed through the holes 14a and 15a (see FIG. 6). Specifically, for example, one end side of the cord 20, in which the hook portion 21 is provided in advance at the other end side, is passed through the holes 14a and 15a before fixing to the unmanned airplane D. Thereafter, one end side of the string 20 is fixed to the unmanned airplane D. As shown in FIG. 7, when the unmanned airplane D ascends by flying and lifts the sleeve 10 via the cord 20, the attachment parts 14 and 15 are brought close to each other by being caught between the hook 21 and the cord 20. This closes the sleeve 10. The hose H inserted into the closed sleeve 10 is lifted by the unmanned airplane D together with the sleeve 10 and transported by air.

  The control method of the unmanned airplane D is arbitrary. For example, the unmanned airplane D may be provided in advance with a control device including a software program indicating a flight path, or may operate in response to a control command from an external controller. If an external controller is used, the external controller may be configured to include a software program that automatically controls the flight path of the unmanned airplane D, and if necessary, from the installation manager of the hose H It may be the composition which can carry out flight control by accepting the manual control command of the above.

  The hooking portion 21 may be attached to the other end of the cord 20 after the cord 20 is passed through the holes 14a and 15a, for example. In that case, one end side of the cord 20 may be fixed to the unmanned airplane D in advance.

  As described above, according to the present embodiment, the unmanned airplane D lifts up the sleeve 10 having the hose H inserted therein to the air, and transports the hose H together with the sleeve 10 to the laying position. Therefore, the hose H can be transported to the installation position regardless of the state of the installation site (for example, the installation site E1, the installation site E2, etc.) of the hose H. Therefore, the hose H can be laid more reliably. Further, since the hose H is lifted to the unmanned airplane D via the sleeve 10, the stress acting on the hose H by lifting can be dispersed by the sleeve 10, and bending of the hose H at the lifting position can be suppressed.

  Further, the sleeve 10 has a structure in which two half cylindrical portions 11 and 12 are rotatably connected to each other. Therefore, by opening the sleeve 10, the hose H can easily enter the inside of the sleeve 10. Therefore, the operation of passing the hose H inside the sleeve 10 is easier.

  Further, the sleeve 10 is lifted to the unmanned airplane D via a string-like member connected to the unmanned airplane D at one end side. Moreover, each of two half-cylinder parts 11 and 12 has the attaching parts 14 and 15 to which the other end side of a string-like member is attached. For this reason, the unmanned airplane D and the sleeve 10 can be more reliably connected.

(Modification)
FIG. 8 is a perspective view showing a modified example of the sleeve 30. As shown in FIG. FIG. 9 is a view showing a case where the sleeve 30 of FIG. 8 is opened. FIGS. 10 and 11 are views showing an example of the case where the unmanned airplane D is transported through the hose H inside the sleeve 30 of the modification. 8 to 11 are views when the sleeve 30 is viewed along the central axis direction of the sleeve 30. FIG.

  Although the cylindrical sleeve 10 is illustrated in FIGS. 3 to 7, the shape of the sleeve is not limited to the cylindrical shape. In the sleeve, the wall surface constituting the cylinder may be a polygonal shape such as a square. Specifically, as shown in FIG. 8 and FIG. 11, a sleeve 30 of a modified example that can be adopted instead of the sleeve 10 in the above embodiment has a square cross-sectional shape orthogonal to the insertion direction of the hose H (for example, Square) has a wall shaped to draw the four sides.

  The sleeve 30 has two semi-cylindrical portions 31, 32. The two half-cylindrical portions 31 and 32 are half-cylindrical members that form wall surfaces of two sides of the four sides of the square, respectively. The two half-cylindrical portions 31 and 32 are rotatably coupled via the coupling portion 33. The specific configuration of the connecting portion 33 is the same as that of the connecting portion 13 in the above embodiment. The connection part 33 connects one side among two sides which the two half-cylinder parts 31 and 32 respectively have.

  The sleeve 30 has two mounting portions 34,35. The specific configuration of the two mounting portions 34, 35 is the same as the two mounting portions 14, 15 in the above embodiment. The two attachment portions 34 and 35 are provided on the outer peripheral surface side of one of the two sides of the two half-cylinder portions 31 and 32 that are not connected by the connecting portion 33. Although not shown, the two attachment portions 34 and 35 may have holes for attaching the ends of the branch cords 26 and 27, respectively.

  Next, the method of carrying the hose H using the unmanned airplane D and the sleeve 30 will be illustrated. In the modified example, a cord 25 is used as a cord-like member. One end of the cord 25 is one, and the other end is branched into two branched cords 26 and 27. First, for example, as shown in FIG. 9, the sleeve 30 is opened so that the inner peripheral surface side of the cylinder is on the upper side. The hose H is placed on the sleeve 30 in this state, and the ends of the branch cords 26 and 27 are attached to the two attachment portions 34 and 35 (see FIG. 10). Thereafter, as shown in FIG. 11, when the unmanned airplane D to which one end side of the cord 25 is fixed ascends by flying and lifts the sleeve 30 via the cord 25, the branch cords 26 and 27 are pulled up so as to approach each other. As a result, the mounting portions 34 and 35 approach each other, and the sleeve 30 closes. The hose H inserted into the closed sleeve 30 is lifted by the unmanned airplane D together with the sleeve 30 and transported by air.

  The end of the branch cords 26 and 27 is attached to the attachment parts 34 and 35, for example, by inserting the ends of the branch cords 26 and 27 into the holes provided in the attachment parts 34 and 35. Alternatively, hooking portions such as hooks may be provided at the ends of the branch cords 26 and 27 so that the hooks are hooked in the holes provided in the mounting portions 34 and 35. It may be good or other connection method.

  According to a modification, the cross-sectional shape of the sleeve 30 is a polygon (for example, a quadrangle), and when the sleeve 30 is in the open state, the wall surface of the cylinder is placed against a flat mounting surface such as ground. It can be placed along the two sides to be configured.

  The above embodiment is merely an example, and can be appropriately modified without departing from the technical features of the present invention. For example, the string-like member is not limited to the illustrated one such as the string 20, and may be a member that can be used as the same application, and the specific form is not limited to the illustrated one.

  For example, instead of the cord 20, a structure in which a plurality of members are connected like a chain may be employed. In addition, the hooking portion 21 may be a flexible member that can be deformed to a size that allows the holes 14a and 15a to be inserted. When the hooking portion 21 is a member having flexibility, the hooking portion 21 has such elasticity that the hooking portion 21 is not deformed by the weight of the hanging object including the weight of the sleeve 10 and the hose H and slips through the holes 14a and 15a. It is desirable to have.
