Embodiments for Carrying Out the Invention

[0010] Hereinafter, with reference to the drawings, a fueling cart according to an embodiment of the present disclosure will be described.

[0011] (Overview of the fueling cart) Fig. 1 is a perspective view of the fueling cart 1 according to the embodiment. Fig. 2 is a front view of the fueling cart 1. Fig. 3 is a side view of the fueling cart 1. Fig. 4 is a side view showing the internal configuration of the fueling cart 1.

[0012] The fueling cart 1 is used, for example, when fueling the tank of equipment. As shown in Fig. 1, the fueling cart 1 includes a cart body 11, a mounting portion 12, a tank 13 (an example of a second storage tank), a supply pipe 14, a pump 15 (see Fig. 2), and a transmission mechanism 16 (see Fig. 4). A poly tank 17 (an example of a first storage tank) containing oil is placed on the mounting portion 12 arranged on the cart body 11. When an operator moves the fueling cart 1, a plurality of wheels 32, 33 arranged on the cart body 11 rotate. The rotation of the wheel 33 is transmitted to the pump 15 via the transmission mechanism 16 to drive the pump 15, and oil is supplied from the poly tank 17 through the supply pipe 14 to the tank 13 located above the poly tank 17. The transfer of oil from the tank 13 to the tank of the equipment is performed by gravity.

[0013] The fuel supply cart 1 further includes a discharge pipe 18, a support mechanism 19, a lock mechanism 20 (see FIG. 9 described later), and a fuel pipe section 21. The discharge pipe 18 returns oil from the tank 13 to the poly tank 17 to prevent the oil from being supplied too much to the tank 13 and overflowing from the tank 13. The support mechanism 19 supports the supply pipe 14 and the discharge pipe 18. The lock mechanism 20 locks the inlet portion 42 of the supply pipe 14 and the outlet portion 62 (described later) of the discharge pipe 18 at an upper position to facilitate the replacement of the poly tank 17. The fuel pipe section 21 moves oil from the tank 13 to the tank of the equipment.

[0014] (Cart body 11) As shown in FIGS. 2 and 3, the cart body 11 has a lower frame 31, a plurality of wheels 32, a wheel 33, a pair of side frames 34, an upper frame 35, and a handle 36. Here, the side where the handle 36 is provided is defined as the rear direction B, and the direction opposite to the rear direction B is defined as the front direction F. Also, the left side facing the front direction F is defined as the left direction L, and the right side facing the front direction F is defined as the right direction R.

[0015] The lower frame 31 is rectangular in plan view and has a rectangular bottom surface 31a and side surfaces 31b arranged upward from each side of the bottom surface. A placement portion 12 is arranged inside the lower frame 31.

[0016] The wheels 32 are arranged at the four corners of the bottom surface 31a of the lower frame 31. A pair of left and right wheels 32 are arranged at the front end and the rear end of the lower frame 31. As shown in FIG. 2, shaft support plates 37 are arranged on the left and right sides of the wheels 32. The shaft support plates 37 are fixed to the bottom surface 31a of the lower frame 31, and the pair of shaft support plates 37 rotatably support the axles of the wheels 32.

[0017] The wheel 33 is disposed between a pair of wheels 32 at the rear end. The wheel 33 has an axle 33a as shown in FIG. 2. On the left and right sides of the wheel 33, axle support plates 38 are disposed. The axle support plates 38 are fixed to the bottom surface 31a of the lower frame 31. The pair of axle support plates 38 rotatably support the axle 33a. As will be described in detail later, the pump 15 is driven by the rotation of the wheel 33.

[0018] A pair of side frames 34 are disposed upward from the left and right ends of the rear end of the lower frame 31, respectively.

[0019] The upper frame 35 is disposed on the upper part of the side frame 34 and is supported by the side frame 34. The tank 13 is disposed on the upper frame 35. The upper frame 35 is formed in a frame shape along the four sides of the bottom surface 13a of the tank 13, which will be described later.

[0020] The handle 36 is disposed across the pair of side frames 34. The handle 36 is disposed along the left - right direction. The operator holds the handle 36 and pushes the fueling cart 1.

[0021] (Placement portion 12) The placement portion 12 is disposed inside the lower frame 31. As shown in FIG. 1, two poly - tanks 17 can be disposed on the placement portion 12. The two poly - tanks 17 are arranged side by side in the left - right direction as shown in FIG. 1. The placement portion 12 has a rectangular bottom surface 12a (see FIG. 4), side surfaces 12b, and a partition portion 12c (see FIG. 1). The side surfaces 12b are disposed upward from the left, right, front, and rear ends of the bottom surface 12a. The partition portion 12c is disposed along the front - rear direction between the two poly - tanks 17. The front end of the bottom surface 12a of the placement portion 12 is positioned lower than the rear end. Thereby, the poly - tanks 17 placed on the placement portion 12 are disposed in an inclined manner.

[0022] (Tank 13) The tank 13 is in the shape of a rectangular parallelepiped. The tank 13 is supported by the upper frame 35. The tank 13 is disposed above the poly-tank 17 placed on the mounting portion 12. The tank 13 stores the oil supplied from the poly-tank 17.

[0023] As shown in FIG. 4, the tank 13 has a bottom surface 13a, side surfaces 13b, a lid 13c, and a sloshing suppression plate 13d. The bottom surface 13a is fixed on the above-described upper frame 35. The side surfaces 13b are disposed upward from the front, rear, left, and right sides of the bottom surface 13a. The lid 13c is disposed at the upper ends of the side surfaces 13b and is configured to be detachable.

[0024] The sloshing suppression plate 13d suppresses sloshing that occurs when the fueling cart 1 is moved. FIG. 5 is a plan view of the tank 13 showing a state in which the lid 13c is removed.

[0025] As shown in FIG. 5, the sloshing suppression plate 13d is disposed between the left side surface 13bL on the left direction L side and the right side surface 13bR on the right direction R side of the side surfaces 13b so as to be in contact with each of the left side surface 13bL and the right side surface 13bR. As shown in FIG. 4, the sloshing suppression plate 13d has a main body portion 13da and an upper end portion 13db. The main body portion 13da is perpendicular to the front-rear direction and is disposed along the vertical direction. The upper end portion 13db is disposed at the upper end of the main body portion 13da. The upper end portion 13db protrudes in the front-rear direction from the main body portion 13da. The lower end of the sloshing suppression plate 13d is disposed at a predetermined interval from the bottom surface 13a.

[0026] Through holes 13e, 13f, and 13g are formed in the bottom surface 13a. The supply pipe 14 is inserted into the through hole 13e from below. The discharge pipe 18, which will be described later, is inserted into the through hole 13f. A fueling hose 91, which will be described later, is connected to the through hole 13g.

[0027] (Supply pipe 14) In FIG. 3, the supply pipe 14 and the discharge pipe 18 overlap in a side view, making it difficult to see the supply pipe 14 and the discharge pipe 18. Therefore, the supply pipe 14 and the discharge pipe 18 will be described using FIG. 6 in which the supply pipe 14 and the discharge pipe 18 are intentionally shifted in the front-rear direction and the vertical direction. In FIG. 6, the supply pipe 14 is hatched with diagonal lines running from the upper right to the lower left, and the discharge pipe 18 is hatched with diagonal lines running from the upper left to the lower right. Note that the supply pipe 14 and the discharge pipe 18 are shown in the foremost position compared to other components.

[0028] The supply pipe 14 connects the inside of the tank 13 and the poly-tank 17. The supply pipe 14 has an outlet portion 41, an inlet portion 42, and a flexible portion 43.

[0029] The outlet portion 41 can be formed of, for example, a metal pipe or the like. The outlet portion 41 is arranged in the vertical direction. The outlet portion 41 is inserted into the through-hole 13e of the tank 13. An opening 41a is formed at the tip of the outlet portion 41, and oil is discharged into the tank 13 from the opening 41a. The lower end 41b of the outlet portion 41 is located below the tank 13 and is connected to a pump 15 described later.

[0030] The inlet portion 42 can be formed of, for example, a metal pipe or the like. The inlet portion 42 is inserted into the opening 17a (shown by a two-dot chain line in FIG. 4) of the poly-tank 17 from above. As shown in FIG. 6, the inlet portion 42 has a first portion 421, a second portion 422, and a third portion 423. The first portion 421 has an oil inlet at the lower end and is arranged along the vertical direction. The second portion 422 is arranged substantially rearward from the upper end of the first portion 421. The second portion 422 is inclined so as to descend toward the first portion 421. The third portion 423 is arranged to extend downward from the rear end of the second portion 422. Note that in order to suck up oil from the poly-tank 17 as much as possible without leaving any, a flexible pipe or the like may be arranged at the lower end of the first portion 421.

[0031] The flexible portion 43 has flexibility and can be formed by a hose of an elastic member such as rubber. The flexible portion 43 connects the pump 15 and the lower end 423a of the third portion 423.

[0032] (Pump 15, Transmission mechanism 16) The pump 15 pumps up the oil in the poly-tank 17 to the tank 13. The pump 15 is disposed between the outlet portion 41 of the supply pipe 14 and the flexible portion 43 as described above. As the pump 15, for example, a hand-operated pump can be used.

[0033] FIG. 7 is a cross-sectional view showing the configuration of the transmission mechanism 16.

[0034] The transmission mechanism 16 transmits the rotation of the wheel 33 to the pump 15. As shown in FIG. 7, the transmission mechanism 16 includes a case 50, a first gear 51, a second gear 52, a shaft 53, a coupling 54, a roller chain 55, and a tension gear 56.

[0035] The case 50 is disposed so as to surround the second gear 52, the shaft 53, and the roller chain 55. The case 50 is fixed to the lower frame 31 as shown in FIG. 2. The case 50 may be fixed to the side frame 34 or the upper frame 35. The case 50 has a rectangular parallelepiped shape with an opening on the lower surface. The pump 15 is fixed to the left side surface of the case 50 via a bracket 57.

[0036] As shown in FIG. 7, the first gear 51 is fixed to the axle 33a of the wheel 33. The first gear 51 rotates together with the rotation of the wheel 33. The second gear 52 is disposed inside the case 50 and on the rightward R side of the pump 15. The second gear 52 rotates about the left-right direction axis. The second gear 52 is fixed to the shaft 53.

[0037] The shaft 53 is rotatably supported by the case 50. The shaft 53 is arranged along the left - right direction. The shaft 53 is rotatably supported by the left side surface 50a and the right side surface 50b of the case 50. The shaft 53 protrudes leftward from the left side surface 50a of the case.

[0038] The coupling 54 connects the shaft 53 and the pump 15. It connects the end of the shaft 53 protruding leftward from the left side surface 50a and the shaft 15a extending rightward of the pump 15.

[0039] As shown in FIGS. 4 and 7, the roller chain 55 is wound around between the first gear 51 and the second gear 52. Thereby, the second gear 52 rotates with the rotation of the first gear 51.

[0040] As shown in FIG. 4, the tension gear 56 applies tension to the roller chain 55. The tension gear 56 is fixed to the front surface 50c of the case 50 via a bracket. The tension gear 56 is arranged near the center in the up - down direction of the case 50. The tension gear 56 is arranged behind the roller chain 55. The tension gear 56 presses the roller chain 55 from the outside to the inside. The tension gear 56 presses the rear portion of the wound roller chain 55 from the rear to the front. Although not shown, it is preferable that the tension gear 56 can adjust its position in the front - rear direction so as to adjust the tension of the roller chain 55.

[0041] (Poly - tank 17) The poly-tank 17 is a tank made of polyethylene. Oil is stored in the poly-tank 17. The poly-tank 17 has an opening 17a that can be closed with a lid. The poly-tank 17 is placed on the mounting portion 12 such that the opening 17a is positioned forward. As shown in FIG. 4, when placed on the mounting portion 12, the poly-tank 17 is arranged such that the front side (the side of the opening 17a) is lower than the opposite side in the front-rear direction. Thereby, the oil in the poly-tank 17 can be assembled into the tank 13 with as little remaining as possible.

[0042] (Discharge pipe 18) The discharge pipe 18 connects between the tank 13 and the poly-tank 17. As shown in FIG. 6, the discharge pipe 18 has an inlet portion 61, an outlet portion 62, and a flexible portion 63. The inlet portion 61 can be formed by, for example, a metal pipe or the like. The inlet portion 61 is arranged in the vertical direction. The inlet portion 61 is inserted into the through-hole 13f of the tank 13. An opening 61a is formed at the tip of the inlet portion 61, and oil is discharged from the opening 61a into the discharge pipe 18. In the vertical direction, the opening 61a of the discharge pipe 18 is arranged below the opening 41a of the supply pipe 14. Thereby, it is possible to prevent the oil from flowing backward from the opening 41a of the supply pipe 14. The lower end 61b of the inlet portion 61 is located below the tank 13 and is connected to the flexible portion 63.

[0043] The outlet portion 62 can be formed by, for example, a metal pipe or the like. The outlet portion 62 is inserted into the opening 17a of the poly-tank 17 from above. The outlet portion 62 has a first portion 621, a second portion 622, and a third portion 623. The first portion 621 has an oil outlet at the lower end and is arranged along the vertical direction. The second portion 622 is arranged substantially rearward from the upper end of the first portion 621. The second portion 622 is inclined so as to descend as it goes toward the first portion 621. The third portion 623 is arranged downward from the rear end of the second portion 622.

[0044] The flexible portion 63 has flexibility and can be formed by a hose of an elastic member such as rubber. The flexible portion 63 connects the lower end 61b of the inlet portion 61 and the lower end 623a of the third portion 623 of the outlet portion 62.

[0045] Although it is shifted for the sake of explanation in FIG. 6, as shown in FIG. 4, the third portion 423 of the supply pipe 14 and the third portion 623 of the discharge pipe 18 are arranged side by side in the horizontal direction and are of substantially the same size. Also, the second portion 422 of the supply pipe 14 and the second portion 622 of the discharge pipe 18 are arranged side by side in the horizontal direction via the second support member 722 and are of substantially the same size. On the other hand, the first portion 421 of the supply pipe 14 and the first portion 621 of the discharge pipe 18 are arranged side by side in the horizontal direction via the second support member 722, but the first portion 421 extends downward more than the first portion 621.

[0046] (Support mechanism 19) FIG. 8 is a side view of the support mechanism 19. In FIG. 8, for the purpose of showing the support mechanism 19, the configurations of the supply pipe 14, the discharge pipe 18, the oil supply pipe portion 21, etc. are omitted. FIG. 9 is a plan view of the support mechanism 19. FIG. 10 is a front view of the support mechanism 19 (viewed from the front direction). In FIG. 10, for the purpose of explanation, the protruding portion 724 described later is omitted.

[0047] As shown in FIG. 8, the support mechanism 19 has a support rod 71 and a support portion 72. The support rod 71 is arranged along the vertical direction. The upper end of the support rod 71 is fixed to the upper frame 35 via the upper bracket 73. The lower end of the support rod 71 is fixed to the case 50 via the lower bracket 74. A locking groove 71c for locking the support portion 72 by a locking mechanism 20 described later is formed in the circumferential direction at the upper part of the support rod 71.

[0048] As shown in FIG. 9, the support portion 72 supports the inlet portion 42 of the supply pipe 14 and the outlet portion 62 of the discharge pipe 18. The support portion 72 has a first support member 721 and a second support member 722.

[0049] The first support member 721 is rotatably attached to the support rod 71 in the horizontal direction. As shown in FIG. 8, the first support member 721 has a cylindrical portion 723, a plate-shaped protruding portion 724, and a handle portion 725 (see FIG. 10). The support rod 71 is inserted into the cylindrical portion 723. The cylindrical portion 723 is disposed around the support rod 71. The cylindrical portion 723 is slidable in the vertical direction with respect to the support rod 71 (see arrow A shown in FIG. 8). The cylindrical portion 723 is rotatable in the horizontal direction about the support rod 71 (see arrow C shown in FIGS. 8 and 9).

[0050] As shown in FIG. 10, the handle portion 725 is disposed on the cylindrical portion 723. The operator can grip the handle portion 725 to slide the cylindrical portion 723 in the vertical direction.

[0051] As shown in FIG. 8, the protruding portion 724 protrudes outward from the outer surface of the cylindrical portion 723. The main surface of the protruding portion 724 is disposed parallel to the vertical direction. At the tip of the protruding portion 724, the second support member 722 is rotatably connected about an axis in the vertical direction (see D in FIG. 8) (see arrow E in FIG. 9).

[0052] As shown in FIGS. 8 and 9, the second support member 722 is a plate-shaped member, and the main surface is disposed parallel to the vertical direction. The second support member 722 is attached to the tip of the protruding portion 724 so as to be swingable in the left-right direction about the axis D (see FIG. 8) with respect to the protruding portion 724 (see arrow E in FIG. 9). On both sides of the second support member 722, the inlet portion 42 of the supply pipe 14 and the outlet portion 62 of the discharge pipe 18 are disposed. The outlet portion 62 of the discharge pipe 18 is fixed to the main surface on the right side of the second support member 722. The inlet portion 42 of the supply pipe 14 is fixed to the main surface on the left side of the second support member 722.

[0053] Thus, since the support portion 72 is slidable in the vertical direction with respect to the support rod 71, the inlet portion 42 of the supply pipe 14 and the outlet portion 62 of the discharge pipe 18 can be inserted into and removed from the poly tank 17.

[0054] Further, the support portion 72 is rotatable about the support rod 71, and furthermore, the first support member 721 is swingable about the vertical axis D with respect to the second support member 722. Therefore, the inlet portion 42 of the supply pipe 14 and the outlet portion 62 of the discharge pipe 18 can move between the two poly tanks 17 arranged side by side in the left - right direction as shown in FIG. 1.

[0055] (Lock mechanism 20) The lock mechanism 20 locks the support portion 72 at the upper position of the support rod 71. FIG. 11(a) is a side view showing the state where the support portion 72 is locked at the upper position. FIG. 11(b) is a plan view showing the positional relationship between the support rod 71 and the locking member 81 in the state where the support portion 72 is locked at the upper position. FIG. 12(a) is a side view showing the state where the support portion 72 is unlocked. FIG. 12(b) is a plan view showing the positional relationship between the support rod 71 and the locking member 81 in the state where the support portion 72 is unlocked.

[0056] The lock mechanism 20 has, as shown in FIG. 11(a), a locking member 81, a spring member 82, and a protrusion 83. The locking member 81 is a plate - shaped member in which a through - hole 81a is formed. The support rod 71 passes through the through - hole 81a. The locking member 81 has a pressing portion 811 and a mounting portion 812. The pressing portion 811 is the portion that is pressed downward by the operator when sliding the support portion 72 vertically with respect to the support rod 71. The spring member 82 is attached to the mounting portion 812 of the locking member 81. The mounting portion 812 is arranged on the opposite side of the pressing portion 811 with the through - hole 81a in between.

[0057] The spring member 82 is, for example, a coil spring and is arranged vertically along the side surface of the cylindrical portion 723. The upper end of the spring member 82 is attached to the mounting portion 812 of the locking member 81. The lower end of the spring member 82 is attached to the protrusion 83 arranged on the side surface of the cylindrical portion 723.

[0058] Since the mounting portion 812 of the locking member 81 is biased downward by the spring member 82, when the pressing portion 811 is not pressed downward by the operator, as shown in Fig. 11(a), the pressing portion 811 moves upward. For this reason, the edge portion 81ae of the through-hole 81a abuts against the support rod 71. When the edge portion 81ae abuts against the support rod 71 at the portion where the above-described locking groove 71c is arranged, as shown in Figs. 11(a) and 11(b), the edge portion 81ae fits into the locking groove 71c. In this state, since the locking member 81 is locked in the locking groove 71c, the position of the support portion 72 can be fixed.

[0059] On the other hand, as shown by the arrow F, when the operator presses the pressing portion 811 of the locking member 81 downward from above, the pressing portion 811 moves downward as shown in Fig. 12(a). Further, as shown in Fig. 12(b), the edge portion 81ae of the locking member 81 is separated from the locking groove 71c. Therefore, the support portion 72 can slide in the vertical direction with respect to the support rod 71 without the locking member 81 interfering with the locking groove 71c.

[0060] (Fuel supply pipe portion 21) As shown in Figs. 1 and 3, the fuel supply pipe portion 21 includes a fuel supply hose 91 and a fuel supply gun 92. One end of the fuel supply hose 91 is connected to a through-hole 13g formed in the bottom surface 13a of the tank 13. The other end of the fuel supply hose 91 is connected to the fuel supply gun 92. The fuel supply gun 92 can discharge oil from the fuel supply gun 92 by pulling a trigger. The fuel supply gun 92 is inserted into a gun holder 93 attached to the upper frame 35.

[0061] Since the tank of the facility equipment is arranged below the tank 13, by inserting the fuel supply gun 92 into the tank of the facility equipment and pulling the trigger, the oil can be moved from the tank 13 toward the tank of the facility equipment by gravity.

[0062] <Operation> The operation of the fuel supply cart 1 of the present embodiment will be described.

[0063] First, with the pressing portion 811 of the locking member 81 of the locking mechanism 20 pushed downward, hold the handle portion 825 and move the support portion 72 upward (see Fig. 12(a)). By releasing the pressing of the pressing portion 811 and locking the edge portion 81ae of the through hole 81a of the locking member 81 in the locking groove 71c, the support portion 72 is locked at the upper position of the support rod 71 (see Fig. 11(a)).

[0064] With the support portion 72 locked upward, two oil-filled poly tanks 17 are placed on the placement portion 12.

[0065] Next, with the pressing portion 811 of the locking member 81 of the locking mechanism 20 pushed downward, hold the handle portion 825 and move the support portion 72 downward so that the inlet portion 42 of the supply pipe 14 and the outlet portion 62 of the discharge pipe 18 are inserted into the opening 17a of one of the poly tanks 17 from above (see Fig. 1).

[0066] Next, the operator holds the handle 36 and moves the fueling cart 1 to the tank of the equipment. As the fueling cart 1 moves, the wheel 33 also rotates together with the wheel 32 (see Figs. 4 and 7). When the wheel 33 rotates, the first gear 51 fixed to the axle 33a also rotates, and the roller chain 55 also rotates. The rotation of the roller chain 55 causes the shaft 53 to rotate together with the second gear 52. The rotation of the shaft 53 causes the shaft 15a of the pump 15 connected by the coupling 54 to rotate, and the pump 15 is driven. The driving of the pump 15 causes the oil in the poly tank 17 to move through the supply pipe 14 to the tank 13. When the amount of oil becomes higher than the opening 61a of the inlet portion 61 of the discharge pipe 18, the excess oil in the tank 13 is returned to the poly tank 17 through the discharge pipe 18.

[0067] When the fueling cart 1 is moved to the equipment 100, pull out the fueling gun 92 from the gun holder 93 and insert it into the tank 110 of the equipment 100 as shown in Fig. 13. In that state, by pulling the trigger of the fueling gun 92, the oil moves from the tank 13 to the tank 110 of the equipment 100 by gravity.

[0068] In addition, when the oil in one of the poly tanks 17 runs out, by pushing down the pressing portion 811 and then moving the support portion 72 upward, the inlet portion 42 of the supply pipe 14 and the outlet portion 62 of the discharge pipe 18 are pulled out upward from one of the poly tanks 17. Then, as shown in FIG. 9, while rotating the support portion 72 with respect to the support rod 71 and swinging the first support member 721 in the left - right direction with respect to the second support member 722, the inlet portion 42 of the supply pipe 14 and the outlet portion 62 of the discharge pipe 18 can be arranged above the other poly tank 17. Then, with the pressing portion 811 of the locking member 81 of the locking mechanism 20 pushed downward, by gripping the handle portion 825 and moving the support portion 72 downward, the inlet portion 42 of the supply pipe 14 and the outlet portion 62 of the discharge pipe 18 are inserted into the opening 17a of the other poly tank 17 from above.

[0069] (Features, etc.) (1) The fueling cart 1 of the present embodiment includes a cart body 11, a mounting portion 12, a tank 13 (an example of a second storage tank), a supply pipe 14, and a pump 15. The cart body 11 has wheels 33 (an example of wheels). The mounting portion 12 is arranged on the cart body 11, and a poly tank 17 (an example of a first storage tank) for storing oil is placed thereon. The tank 13 is arranged at a position higher than the mounting portion 12 of the cart body 11 and stores oil. The supply pipe 14 supplies oil from the poly tank 17 placed on the mounting portion 12 to the tank 13. The pump 15 is driven by the rotation of the wheels 33 and moves oil from the poly tank 17 placed on the mounting portion 12 to the tank 13 via the supply pipe 14.

[0070] When the fueling cart 1 is moved, the wheels 33 rotate and the pump 15 is driven, and the oil is lifted from the poly tank 17 to the tank 13. Therefore, for the tank of the equipment, since it is only necessary to move the oil from the tank 13 by gravity, it becomes possible to easily supply fuel to the tank of the equipment.

[0071] (2) The fueling cart 1 of the present embodiment further includes a discharge pipe 18. The discharge pipe 18 has an opening 61a (an example of an inlet) disposed at a predetermined height inside the tank 13, and returns the oil in the tank 13 from the opening 61a (an example of an inlet) to the poly tank 17.

[0072] Thereby, it is possible to prevent oil from overflowing from the tank 13.

[0073] (3) In the fueling cart 1 of the present embodiment, the opening 41a (an outlet of oil) of the supply pipe 14 in the tank 13 is disposed at a position higher than the opening 61a of the discharge pipe 18.

[0074] Thereby, it is possible to prevent the oil from flowing back from the supply pipe 14 to the poly tank 17.

[0075] (4) The fueling cart 1 of the present embodiment further includes a fueling hose 91 and a fueling gun 92. The fueling hose 91 supplies oil from the tank 13 to a storage tank disposed in the facility.

[0076] Thereby, it is possible to replenish the oil to the tank of the facility equipment via the fueling hose 91 and the fueling gun 92.

[0077] (5) In the fueling cart 1 of the present embodiment, the supply pipe 14 has an inlet portion 42 (an example of a tip portion) that is inserted into the poly tank 17 placed on the placement portion 12 from above. The fueling cart 1 further includes a support portion 72 and a support rod 71. The support portion 72 supports the inlet portion 42. The support rod 71 supports the support portion 72 so as to be slidable in the vertical direction.

[0078] Thereby, it is easy to insert the inlet portion 42 into the poly tank 17 from above, and it is easy to remove the inlet portion 42 from the poly tank 17.

[0079] (Other embodiments) As described above, one embodiment of the present invention has been explained. However, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the invention.

[0080] (A) In the above embodiment, the tank 13 is used as an example of the second storage tank. However, it does not have to be fixed to the upper frame 35 and may be removable.

[0081] (B) In the above embodiment, the poly tank 17 is cited as an example of the first storage tank. However, it does not have to be limited to a poly tank and may be a metal tank.

[0082] (C) In the above embodiment, the discharge pipe 18 is provided. However, if the transmission from the wheel 33 to the pump 15 can be released by means such as releasing the connection by the coupling 54, the discharge pipe 18 does not have to be provided.

[0083] (D) In the above embodiment, the roller chain 55 is wound between the first gear 51 and the second gear 52. However, it is not limited to a roller chain, and a belt or the like may be used.
