Description

  The present invention relates to a tank storage stand used for storing an external fuel tank equipped in a jet fighter.

  A storage platform is usually used to store the off-board fuel tanks installed in jet fighters. A typical conventional storage stand has a two-stage rack structure in which a total of four storage tanks are stored on each side of the center line in order to efficiently store the external fuel tank. And when using an out-of-machine fuel tank, this is transferred from a storage stand to a tank transport carriage and transported to the airframe. On the other hand, the external fuel tank removed from the airframe after use is transported to the storage base by the tank transport carriage.

  However, such a conventional storage table has the following problems with respect to tank loading and unloading. An empty tank is stored on the storage stand, and even if it is empty, its weight is about 160 kg. Its diameter is close to 1 m. For this reason, until now, more than four people have been loading and unloading. As a result, this loading and unloading work was very inefficient. In addition, since loading into the upper stage and unloading from the upper stage involve work at a high position, equipment such as cranes and forklifts were also required.

  Although it is conceivable to mechanize the tank loading and unloading work at the storage stand, the work, especially the transfer work from the storage stand to the transport cart, is mostly urgent because the tank is installed in a short time due to the characteristics of the fighter. As usual, there was a situation where it was impossible to deal with it unless it was a human naval tactic. That is, when mechanized, although the burden on the operator is reduced, a quick work such as human naval tactics is difficult and there is a risk that the emergency situation cannot be dealt with.

  The object of the present invention is to perform the work of exchanging the fuel tank outside the tank with the tank carrier truck without the need for equipment such as cranes and forklifts, and with a small number of personnel without difficulty, and also for quick work that can respond to an emergency situation. The objective is to provide a functional tank storage.

  In order to achieve the above object, a tank storage stand according to the present invention is provided for a storage stand body that supports an external fuel tank in a plurality of stages on both sides of a center line, and a tank transport carriage that is placed on the storage stand body. The tank loading / unloading mechanism is provided on the storage base to transfer the external fuel tank, and the tank unloading mechanism is erected on the center line of the storage base and the horizontal arm extends from the upper end to both sides. The T-shaped fixed frame and the arm portion of the fixed frame are pulled out to the outside of the storage base body as a slide guide, and the fuel tank on the outside of the tank transportation carriage on the tank transport carriage that is laid on the storage base body is lifted at the drawing position. And a pair of left and right sliding lifting devices configured as described above.

  In the tank storage stand of the present invention, a tank loading / unloading mechanism is provided on the storage stand body that supports the external fuel tank in multiple stages on both sides of the center line. The tank loading / unloading mechanism is equipped with a pair of left and right sliding lifting devices using a horizontal arm portion of a T-shaped fixed frame standing on the center line of the storage base body as a slide guide. The T-shaped fixed frame does not interfere with the external fuel tanks mounted in multiple stages on both sides of the center line of the storage base body. The pair of left and right sliding lifting devices are pulled out to the outside of the storage base body, and lift the external fuel tank on the tank transport carriage that is laid on the storage base body. That is, each lifting device lifts the tank outside the storage base body, pulls it into the storage base body, and places it.

  The tank loading / unloading mechanism uses a T-shaped fixed frame, and does not interfere with the main body of the storage base because the lifting / lowering work is performed outside the storage base by the sliding lifting devices on both sides. For this reason, the storage base body can adopt substantially the same structure as the conventional storage base and can support an ideal position reinforced by ribs or the like in the tank. As for the tank transportation cart that is placed next to the storage base body, the conventional one can be used as it is, which is economical. Each of the slide-type lifting devices on both sides can use the entire horizontal portion of the T-shaped fixed frame, that is, one end to the other end of the horizontal arm portion on both sides as a slide guide. For this reason, stability is high also when the sliding type lifting device on one side is pulled out to the outside of the storage base body. Since the slide operation does not require labor, it can be performed manually and instantaneously, thereby enabling a quick operation.

  The storage base body is preferably configured to support an external fuel tank at two front and rear locations on each stage on both sides of the center line. As a result, the tank can be supported at an ideal position reinforced by ribs or the like in the tank as usual. In this case, it is only necessary to equip one tank unloading mechanism between the two tank support positions.

  The storage base body is also preferably mobile with wheels. In that case, it is preferable that a traction lever is attached on the center line of the front part and the rear part, and the traction lever is rotatable on both sides so that it also serves as an outrigger in the rotation position. With this configuration, the stability when the tank is operated on one side of the storage base body can be further improved.

  A set of left and right sliding lifting devices combines a horizontal portion that slides along either the front or rear surface of the horizontal portion of the fixed frame and a vertical portion that hangs downward from the outer end of the horizontal portion. An inverted L-shaped movable frame is provided, and a winch for lifting the tank is provided near the side end of the horizontal portion of the movable frame, and the operation portion for operating the movable frame and the winch is provided at the lower end of the vertical portion of the movable frame. A configuration equipped in the vicinity is preferable. With this configuration, the operation unit is lowered to a low position, and the operability is particularly good.

  The tank storage stand according to the present invention includes a storage stand main body that supports the external fuel tank in multiple stages on both sides of the center line, and a horizontal arm portion of a T-shaped fixed frame that is erected on the center line of the storage stand main body. A tank loading and unloading mechanism equipped with a pair of left and right sliding lifting devices that serve as slide guides, so that the external fuel tank can be used as a crane, forklift, etc. It can be exchanged with a small number of people without using it, contributing to rationalization. In addition, it is possible to perform a quick operation capable of responding to an emergency and is very functional.

The cross member 42 projecting from both sides of the support column 41 is made of an H-shaped material, and is fixed in such a posture that two opposing flanges are horizontal in the vertical direction and the web between the vertical flanges is vertical.

  The pair of left and right slide lifting devices 50, 50 are attached to a cross member 42 of the fixed frame 40. Each of these lifting devices 50, 50 has an inverted L-shaped movable frame 60 and a tank lifting winch 70 attached thereto. The movable frame 60 includes a horizontal portion 61 having substantially the same length as the cross member 42 of the fixed frame 40, and a vertical portion 62 that hangs downward from the outer end of the horizontal portion 61. As a guide, it is supported so as to be slidable in the horizontal direction. In order to avoid interference between the horizontal portions 61, 61 of the movable frames 60, 60, one horizontal portion 61 is fitted between the upper and lower flanges on the front side of the cross member 42, and the other horizontal portion 61 The material 42 is fitted between the upper and lower flanges on the rear surface side.

  The movable frame 60 reciprocates between the storage position X and the use position Y by the slide of the horizontal portion 61. In the storage position X, the horizontal portion 61 overlaps the cross member 42. The vertical portion 62 is closest to the cross member 42 of the fixed frame 40 within a range where it does not come into contact with the external fuel tank 10 supported on one side of the storage base body A, and is externally supported on one side of the storage base body A. On the center line of the fuel tank 10, a hanging portion of a wire to be described later is positioned. On the other hand, at the use position Y, the horizontal portion 61 protrudes almost half to the outside of the cross member 42. The vertical portion 62 is separated from the fixed frame 40, and when the tank transport carriage 90 is placed on the storage base body A, the vertical portion 62 is placed on the center line of the external fuel tank 10 placed on the tank transport carriage 90. Position. In order to realize this, the slide amount S to the outside of the movable frame 60 is set to be slightly larger than the diameter of the external fuel tank 10.

  The vertical portion 62 of the movable frame 60 is set to a length approximately half of the height of the fixed frame 40 so that the operator's hand can easily reach the lower end portion thereof. Grips 63 and 63 for manually sliding the movable frame 60 are attached.

  As shown in FIG. 5, the winch 70 has a drum 71 provided in the vicinity of the outer end portion of the horizontal portion 61 of the movable frame 60. Here, the drum 71 is attached to an end portion on the back side of a horizontal rotation shaft 72 rotatably supported on a horizontal support plate 64 extending inward from the upper end portion of the vertical portion 62. The end of the rotating shaft 72 is connected to the output shaft of the self-locking speed reducer 73, and a gear 74 is attached to the input shaft of the self-locking speed reducer 73. The gear 74 is connected to an operation handle 75 attached to the lower end portion of the vertical portion 62 of the movable frame 60 by a chain (not shown), and is manually rotated in both forward and reverse directions by the operation handle 75.

  A wire 76 is wound around the drum 71 of the winch 70. Both ends of the wire 76 extend from the drum 71 in the opposite direction by the same length. One end of the wire 76 extends to the front side of the storage base and hangs downward via a pulley 77, and a hook 78 is attached to the lower end thereof. The other end of the wire 76 extends to the rear side of the storage table and hangs downward via a pulley 77, and a hook 78 is attached to the lower end thereof. The front and rear pulleys 77, 77 are supported at both ends of the arm 65 attached at right angles to the end of the horizontal portion 61 of the movable frame 60, and the distance between both hanging portions of the wire 76 is set at the outside fuel tank 10. It is made to correspond to the space | interval of the hooks 11 and 11 before and behind. Both hanging portions of the wire 76 are supported by front and rear guides 66 and 66 for preventing the fuel tank 10 outside the apparatus from shaking.

  That is, the front and rear guides 66, 66 can be moved up and down along the vertical portion 62 of the movable frame 60, can be rotated in the horizontal direction around each base portion, and the tip portion is a hanging portion of both of the wires 76. Penetrates the tip. And it is supported from below by the hooks 78, 78, and as the hooks 78, 78 are moved up and down, both hanging parts of the wire 76 are supported and hung near the hooks 78, 78. Stop touching the outer fuel tank 10.

  The front and rear hooks 11, 11 of the external fuel tank 10 are provided in the vicinity of the center of the tank and are sufficiently closer to the center than the front and rear support positions by the storage base A.

  Next, the usage method and function of the tank storage stand of this embodiment will be described. First, a case where the off-machine fuel tank 10 is carried into the tank storage table will be described.

  In the tank unloading mechanism B, the movable frames 60, 60 of the slide type lifting devices 50, 50 on both sides are pushed into the storage position X. Both hanging portions of the wires 76 and 76 in the winches 70 and 70 are wound up to the upper limit.

  The out-of-machine fuel tank 10 removed from the airframe is placed on a conventionally used towed tank transport carriage 90 and carried to the tank storage base. The tank transport carriage 90 is placed next to the base portion 20 of the storage base body A. The movable frame 60 of the lifting device 50 on the side that is laid sideways is pulled out to the outer use position Y. Specifically, the operator holds the grips 63 and 63 with both hands and pulls out the movable frame 60 to the outside. As a result, both hanging portions of the wire 76 in the winch 70 are positioned directly above the hooks 11 and 11 of the external fuel tank 10 placed on the tank transport carriage 90. In this state, the handle 75 is operated in a direction in which both hanging portions of the wire 76 are lowered. Hooks 78 and 78 attached to the lower ends of both hanging parts are hooked on the hooks 11 and 11 of the external fuel tank 10. The handle 75 is operated in the reverse direction to wind up both hanging portions of the wire 76 around the drum 71, and the external fuel tank 10 is pulled up.

  When the out-of-machine fuel tank 10 is pulled up to a lower level of the storage base body A, that is, to a height at which it can be placed on the frame portion 20, the movable frame 60 of the lifting device 50 is pushed into the inner storage position X. The external fuel tank 10 is placed on one side of the frame portion 20 by operating the handle 75 and slightly lowering both hanging portions of the wire 76. Thus, the out-of-machine fuel tank 10 is stored on the lower side of the storage base body A without using equipment such as a crane and a forklift.

  The next out-of-machine fuel tank 10 is similarly stored on the opposite side of the lower stage of the storage base body A. The next out-of-machine fuel tank 10 is stored on either side of the upper stage of the storage base body A.

  Specifically, the tank transport carriage 90 on which the out-of-machine fuel tank 10 is mounted is placed on the storage base body A, and the movable frame 60 of the lifting device 50 is pulled out to the outside use position. The handle 75 is operated to lower both hanging portions of the wire 76 and hooks 78, 78 are hooked on the hooks 11, 11 of the external fuel tank 10. The handle 75 is operated in the reverse direction to wind up both hanging portions of the wire 76 around the drum 71, and the external fuel tank 10 is pulled up.

  When it is pulled up to the upper level of the storage base body A, that is, the height that can be placed on the front and rear tank support portions 30, 30, the movable frame 60 of the lifting device 50 is pushed into the inner storage position X. At this time, there is no interference with the external fuel tank 10 stored in the lower stage. By operating the handle 75 and slightly lowering both hanging portions of the wire 76, the external fuel tank 10 is placed on one side of the tank support portions 30 and 30. Thus, the out-of-machine fuel tank 10 is accommodated on one side of the upper stage of the storage base body A without using equipment such as a crane and a forklift.

  The last out-of-machine fuel tank 10 is similarly stored on the opposite side of the upper stage of the storage base body A. In this way, the four out-of-machine fuel tanks 10 are stored in order from the bottom on both sides of the center line of the storage base body A. One worker is sufficient, and it is sufficient that there are two workers, and a significant rationalization is achieved as compared with the conventional four or more. Moreover, there is no need to use equipment such as cranes and forklifts.

  When loading the external fuel tank 10 on the side of the storage base A, the center of gravity moves to the loading side, but the weight of the tank storage base, the position of the center of gravity, etc. are designed so as not to fall over. In addition, loading work is always prioritized at the bottom. If the upper stage is loaded first, both hanging portions of the wire 76 interfere with the upper external fuel tank 10, and the lower stage cannot be loaded. Due to this restriction, when loading into the upper stage, the outboard fuel tank 10 is stored in the lower stage, which also contributes to the improvement of stability. If the front and rear tow bars 24, 24 are rotated to the working side, this functions as an outrigger, and stability and safety are further improved.

  When the out-of-machine fuel tank 10 is unloaded from the storage base A, the upper-stage out-of-machine fuel tank 10 is used by using the slide-type lifting devices 50 and 50 on both sides of the tank unloading mechanism B and in the reverse order of the loading. Are transferred to the tank transport cart 90 in order.

  This operation can also be performed quickly by sliding operation of the lifting device 50, rotating operation of the handle 75 and hooking of the hooks 78 and 78, and since one or two workers are sufficient, significant rationalization is possible. It becomes. Also, the work is easy and the burden on the operator is reduced. Furthermore, there is no need to use equipment such as cranes and forklifts. And most of all, it is possible to work very quickly, so that it can be handled without problems even if it is attached to a fighter plane in an emergency.

  In addition to this, in the rack storage stand of this embodiment, a self-locking reduction gear 73 is interposed between the drum 71 and the handle 75. For this reason, not only can the up-and-down operation of the out-of-machine fuel tank 10 be performed easily, but the drum 71 does not rotate freely even if the handle 75 is released. For this reason, operation becomes easier and safety higher than anything is ensured.
