Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to industrial vehicles such as forklifts and power shovels, and specifically relates to a mounting device for installing an air cleaner outside the engine room.

(Prior Art) Generally, in industrial vehicles such as forklifts, standard air cleaners are installed in the engine room, but in the case of large air cleaners that cannot be installed in the engine room, It is common to install it on a counterweight 21 as shown in the figure. As shown, the air cleaner 22 is installed on the counterweight 21 via a mounting band 23, and the purified air outlet 24 is connected to a connector hose 25, a connector pipe 26, a connector hose 27 and an intake manifold 28.
It is connected to the engine 29 via. A connector pipe 26 passes through the radiator cover 30 and connects the inside and outside of the engine room.
Normally, this connector pipe 26 is fixed to the radiator cover 30.

(Problems to be Solved by the Invention) Incidentally, when performing service work such as maintenance and inspection, it may be necessary to attach and detach the radiator cover 30, but at this time the connector pipe 26 Since the cover 30 is penetrated, the connector hoses 25 and 27 at the front and rear of the connector pipe 26 must be attached and detached from the connector pipe 26, making it very difficult to attach and detach the radiator cover 30.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide an air cleaner mounting device that is easy to attach and detach a radiator cover during service work.

(Means for Solving the Problems) In order to solve the above problems, the present invention divides the radiator cover that closes the engine compartment together with the engine hood into at least two parts, and one of the divided cover members The air cleaner is mounted on the pedestal of the air cleaner, and an introduction passage for introducing the air purified by the air cleaner to the engine is piped through the cover member on the side where the cleaner is mounted.

(Function) By dividing the radiator cover and using one of them as a mounting stand for the air cleaner, the radiator cover on the side where the air cleaner is not mounted can be removed without interference from the air cleaner and its piping. The cover member for placing the cleaner is set to the minimum size necessary to place the cleaner, and the reduction in the opening area due to not removing the cover member for placing the cleaner is minimized. I'm suppressing it.

(Example) Hereinafter, an example of the present invention will be specifically described based on FIGS. 1 to 3. As shown in the figure, the radiator cover 1 is located between the engine hood 2 and the counterweight 3, and covers the radiator 4 at the rear upper surface of the engine room. The radiator cover 1 is divided into two parts, left and right, and in this embodiment, the right cover member 1R is used as a cleaner mounting stand, and is set to the minimum size necessary for installing the air cleaner 12. . Therefore,
It is set much smaller than the left cover member 1L. Thus, the cover member 1R is attached to a bracket (not shown) attached to the frame 5 on the outside at two locations with bolts 6, and is provided with cover mounting plates 7 with screw holes 7a at two locations on the inside, that is, on both sides of the split. ing. On the other hand, the outer side of the cover member 1L on the non-cleaner mounting side is the frame 5.
It is attached at two locations with bolts 8 to a bracket (not shown) attached to the cover, and the split surface side is attached to the cover attachment plate 7 with bolts 9. In other words, the cover member 1L on the non-cleaner mounting side, which has a large area, has two bolts 8 on the left and right,
By removing 9, it can be attached and detached as before.

As shown in FIG. 3, two angled support bars 10 are fixed in parallel in the front and back direction on the cover member 1R as the cleaner mounting table, and the air cleaner 12 is attached to the two support bars 10 in the front and rear directions. It is attached via an attachment band 11. Note that the mounting band 11 is fixed to the support bar 10 by, for example, welding. Further, a connector pipe 13 is fixed to the front end of the cover member 1R in a vertically penetrating state, and one end of the connector pipe 13 is connected to the outlet 14 of the air cleaner 12 via a connector hose 15, as shown in FIG. , the other end is connected to an intake manifold 18 of the engine 17 via a connector hose 16. In addition,
19 is the rear pillar of the head guard.

In this embodiment, as described above, the radiator cover 1 is divided into two parts, and the right cover member 1R is used for attaching the air cleaner 12 and its piping parts.
can be freely removed by removing bolts 8 and 9. That is, according to this embodiment,
The radiator cover 1L can be easily attached and detached without having to attach or detach any piping parts when attaching or detaching the radiator cover, which was necessary in the past.

Next, another embodiment of the present invention will be described based on FIG. 4. In this embodiment, the radiator cover 1 is divided and one of the divided cover members 1R is used for attaching the air cleaner 12 and piping parts, and in addition, the rear pillar 19 is used to take in outside air to the air cleaner 12. Outside air is sucked in from an air intake port 20 opened at the top of the rear pillar 19, passes through the hollow interior, and is introduced into the inlet 23 of the air cleaner 12 via a joint hose 22. It is also possible to consider using the rear pillar 19 as a part of the passage for introducing the air purified by the air cleaner 12 to the engine 17, but in that case, although it may improve the ease of attaching and detaching the radiator cover 1, it is expensive. The purpose of getting as clean air as possible at the location cannot be achieved.

However, according to this embodiment, relatively clean outside air can be taken in from a high position without impairing the removability of the radiator cover as in the previous embodiment, that is, the removability of the cover member 1L on the side where the cleaner is not installed. It is possible to enter it.

Note that the cleaner mounting device of the present invention is applicable not only to forklifts but also to other industrial vehicles such as power shovels.

(Effects of the invention) As detailed above, according to the invention, the radiator cover on the side where the cleaner is not installed can be easily attached and detached without having to attach or detach the cleaner piping parts, compared to the conventional method. It is possible to improve workability when performing service work such as maintenance and inspection. Furthermore, the air cleaner mounting device of the present invention can be easily mounted on existing vehicles by replacing piping parts.
