As mentioned above, if the fuel tank 6 is placed inside the engine compartment, the temperature of the fuel in the tank will rise, which is dangerous, so it is generally placed adjacent to the hydraulic oil tank 5 outside the engine compartment. be. In general hydraulic machinery for civil engineering and construction, the hydraulic oil tank 5 and fuel tank 6 are arranged adjacent to each other, so it is easy to make mistakes when refueling. tank 5
This caused serious problems such as incorrectly filling the fuel tank with hydraulic oil or hydraulic oil incorrectly filling the fuel tank. In addition, there are some hydraulic machines such as backup machines where the hydraulic oil tank and fuel tank are not placed next to each other due to their structure, but even in this case, the caps of both tanks can be easily removed, and even in case of accidental refueling, Even if a warning sign is installed near the cap of the fuel filler port to prevent this, it may become invisible due to dirt from work, adhesion of oil, damage, wear, etc. during long-term use, and incorrect fuel filling may occur. It happened frequently.

This invention was devised to solve the above problems, and has a long replacement cycle (approximately) compared to fuel.
1000 hours) A holder such as a frame or a lid can be attached and removed with a fixing device such as a bolt near the oil filler port so as to cover the cap of the oil filler port of the hydraulic oil tank that stores hydraulic oil. This makes it possible to distinguish between a hydraulic oil tank and a fuel tank, and prevents incorrect refueling of hydraulic machines.

Therefore, the cap of the hydraulic oil tank can only be opened by releasing the attachment of the fixing device, removing the holder, and then opening the oil filler port. The structure that prevents the cap from being easily removed and the presence of the holder serve as an indicator that the tank in question contains "hydraulic oil."

Next, details of the present invention will be explained based on the illustrated embodiments. FIGS. 1 and 2 illustrate a backup as a hydraulic construction machine to which the present invention is applied, and since the overall structure has already been explained, a description thereof will be omitted. In the illustrated embodiment, a holder 10 made of a substantially U-shaped frame is provided on the cap 9 of the oil filler port 11 of the hydraulic oil tank 5. As shown in FIG. A fuel inlet 11 is provided at the top, and a hydraulic fluid outlet 1 is provided at the side of the hydraulic fluid tank 5.
2 and a return hydraulic oil inlet 13 are provided. Then, the cap 9 is screwed into the oil supply port 11 via the strainer 14. On the other hand, reference numeral 10 denotes a holder, which is made of a U-shaped frame made by bending a metal plate.After attaching the cap 9, the holder 10 is inserted into the screw hole 16' provided in the flange 16 of the fuel filler port 11 with a bolt 15. Thus, the lower end bent pieces 10', 10' of the holder 10 are screwed together and fixed through the holes provided on the lower end bent pieces 10'. Therefore, the cap 9 is opened and closed during refueling by attaching and detaching the bolts 15 of the holder 10 to and from the screw holes 16' of the flange 16, and then attaching and detaching the holder 10 to and from the flange 16. The present invention is constructed as described above, but since the hydraulic oil exchange cycle is as long as approximately 1000 hours and refueling is not performed frequently, it is not very complicated to attach and remove bolts during refueling. . Therefore, this can prevent incorrect lubrication. Although the above-mentioned holder 10 uses a U-shaped frame made of a metal material, the material and shape are not limited to this, and plastic or the like may also be used.
Of course, it may also have a U-shape or a cylindrical shape.

As described in detail above, the incorrect refueling prevention device according to the present invention is used in a hydraulic machine having a fuel tank and a hydraulic oil tank, and a cap that can be covered over the fuel filler port of both tanks. A holder consisting of a frame or a lid is attached at the lower end of the holder to the vicinity of the fuel filler port with a fixing device such as a bolt so as to cover the cap, and the holder is detachably provided. It has an extremely simple configuration and can be installed without making any special changes to conventional machines or requiring special tools.This also makes it easy to distinguish between the fuel tank and the operating tank, so it can be installed reliably. Prevents incorrect lubrication.
