Description

[Detailed explanation of the invention] The invention is based on a work platform that is equipped with a worktable that can be raised and lowered.
This relates to a refueling trolley for refueling aircraft.

Conventionally, this type of refueling trolley only had a work platform that could be raised and lowered, and a worker sat on this work platform and connected a refueling hose to the refueling port on the underside of the aircraft's wing to refuel the fuel tank. However, since the lifting range of the work platform is not large, it cannot be used for both large and small aircraft, and separate refueling carts are required for large and small aircraft.

In this invention, a support for supporting a workbench is provided on a trolley so that it can be raised and lowered freely, and the workbench is also provided so that it can be raised and lowered relative to the support, thereby increasing the range of lifting and lowering of the workbench. The purpose of the present invention is to provide a refueling trolley that is capable of refueling both aircraft and small aircraft, and that is simple in structure and easy to operate.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

In Figures 1 to 3, 1 and 1 are engine 3.
A support column 7 is fixed upright on both sides of a self-propelled cart 5 and has a flat outer surface, front surface, and rear surface. Rail parts 11, 11 are arranged side by side in the vertical direction and are fixed to the support body 7, which is made up of a connecting part connecting the groove-like parts on both sides. 9 is a workbench, and upper rollers 13, 13 provided on both sides of the front end and lower rollers 15, 15 provided at appropriate positions below the upper rollers 13, 13 engage with the rail portions 11, 11 and roll to work. The table 9 is moved vertically along the support 7. Reference numeral 17 is a hydraulic main cylinder installed between the column 1 and the support 7 to move the support 7 up and down; 19 is a hydraulic main cylinder installed between the support 7 and the workbench 9 to move the workbench 9 as a supporter; This is a hydraulic sub-cylinder that moves up and down relative to 7. The main cylinder 17 and the sub-cylinder 19 are operated by a pump (not shown) operated by an engine or a motor, and are provided to operate sequentially or in conjunction to operate simultaneously, or to operate separately and independently. . 2
Reference numeral 1 denotes a refueling hose whose one end communicates with a refueling vehicle (not shown), and a connecting fitting 23 connected to a refueling port (not shown) of a fuel tank of an aircraft is provided at the tip. Reference numeral 25 denotes an arm for holding the connecting fitting 23, which is pivotally attached to the front plate 22 of the workbench 9 so as to be able to swing freely;
A holding part 24, which is moved up and down by an operating cylinder 27 and supports a connecting fitting 23 at its tip, is swingably provided to maintain the horizontal position. 29 is a steering handle, 31 is a control table, and 33 is a handrail. 35
is an auxiliary workbench provided at the end of the workbench 9 with hinges 37, 37 so as to be foldable.

In the above embodiment, the trolley 5 is transported to a position directly below an oil filler port (not shown) on the lower surface of an aircraft wing in the traveling attitude shown in FIG. Next, the auxiliary workbench 35 is rotated in the horizontal direction, and the main cylinder 17 and the auxiliary cylinder 19 are extended by the operation lever of the operation table 31, so that the workbench 9 is raised to an appropriate height. The operating cylinder 27 is raised to raise the connecting fitting 23 to a position close to the fuel filler port of the aircraft, and the position shown in FIG. 1 is taken. Next, the connecting fitting 23 is connected to the oil supply port to perform the oil supply operation. After completing the work, remove the connecting fitting 23 from the fuel filler port and hold it in the holding part 24 of the arm 25.
The main cylinder 17 and the auxiliary cylinder 19 are contracted to lower the work platform 9, the auxiliary work platform 35 is folded, and the trolley 5 is moved from under the wing of the aircraft. Note that the pillars in this invention are square pillars,
It includes a channel-shaped material.

Incidentally, if an operating table 31 for raising and lowering the worktable, refueling, etc. is provided on the workbench 9, the refueling operation will be made easier.

According to the present invention, the lifting range of the work platform can be expanded and both large and small machines can be refueled, and the structure is simple and compact. Since it uses a hydraulic cylinder, the speed of the workbench can be set freely.
