Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an industrial vehicle such as a forklift, and more particularly to an industrial vehicle provided with an under cover suitable for protecting an engine and preventing sound leakage.

[0002]

2. Description of the Related Art In an industrial vehicle, a bottom opening of a machine base is
Usually, it is covered with an under cover for protecting an engine, a hydraulic device and the like incorporated in the space of the machine frame. In consideration of engine repair and maintenance, for example, as shown in FIG. 5, this under cover is detachably attached with bolts 11, 11,... Through brackets 10, 10 provided on the under cover 9. Or, as described in JP-A-6-8856, the undercover is positioned by engaging a hook attached to the undercover with a pin provided on a side plate, and the position of the undercover is determined via a bracket and a stopper pin. A drain hole 12 is cut out near the center of each of the undercovers 9 so that oil can be changed while the undercover 9 is mounted.

[0003]

Since a drain hole is formed near the center of the undercover, foreign matter such as a stone that has been jumped up may jump into the space of the machine base from the drain hole. Therefore, the protection function of the engine is not perfect, and there is a problem that the engine sound leaks from the drain hole. If the drain hole is eliminated in order to solve the problem, the conventional structure requires the undercover to be removed even at the time of oil change, resulting in poor workability.

[0004]

SUMMARY OF THE INVENTION The present invention relates to an industrial vehicle in which the oil can be changed without removing the engine from the under cover. The configuration of the industrial vehicle is as follows. It can be closed with a cover. A guide rail is provided on both sides of the bottom opening of the machine as a means for closing the bottom opening of the machine with a slide-type under cover having no hole. And a slide plate having an engagement member slidable along the guide rail, and between the slide plate and the machine base, at a position where the bottom opening is covered with an undercover. A fixing means for fixing the slide plate to the machine base can be provided. In this case, a fixing plate formed by bending a groove-shaped guide rail on the machine base is attached so that the guide rail projects into the opening, and a hook-shaped engaging member is engaged when the fixing means is released. Thereby, the slide plate can be hooked and supported by hanging.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an industrial vehicle according to the present invention implemented in a forklift will be described with reference to the drawings. FIG.
Is an exploded view of the undercover.
Reference numeral 1 denotes a side frame of the machine frame. An engine (not shown) is installed in a space P sandwiched between the side frames 1 and 1, and a bottom opening of the space P is closed by a slide-type under cover 2. It is possible. The under cover 2 has fixed plates 2a, 2a formed by bending groove-shaped rails 3, and hook-shaped engaging members 4, 4,... To be engaged with the rails 3 of the under cover 2a.
The fixed plate 2a is fixed to the left and right side frames 1, 1 so that the rails 3 protruding into the opening are parallel to each other.

The left and right sides of the slide plate 2b are bent so as to be overlapped with each other in close contact with the back side of the rail 3,
Engaging members 4, 4,... Are fixed at two places before and after the bent portion, respectively.
Is hooked on the rail 3, whereby the slide plate 2b is supported in a hung state, and can slide along the rail 3 in the hung state. Further, when the slide plate 2b is set at a position where the entire surface of the opening is completely closed, the bolt insertion holes 5,
, 6, 6, ... are provided, and nuts 7, 7, ... are fixed to the upper surface of the fixing plate 2a in a coaxial arrangement with the bolt insertion holes 5, 5, ....

In the industrial vehicle having the under cover of the above embodiment, if the slide plate 2b is positioned at a position where the bottom opening is closed and fixed with bolts 8, 8,... Is completely closed by the slide plate 2b having no hole, thereby preventing foreign matter from jumping into the space P and leakage of the engine sound (FIG. 2). When the fixing means is released, that is, when all the bolts 8, 8,.
b does not fall because it is hung by the engaging members 4, 4,... (FIG. 3), and the engaging members 4, 4,. The opening can be opened as needed (FIG. 4). Therefore, the bolts can be removed, the undercover can be shifted halfway to change the oil while hanging, and the oil can be pulled out and removed, and the engine can be repaired or maintained while standing out of the way, depending on the purpose.

As described above, the industrial vehicle of the present invention does not leak sound because there is no drain hole for oil change in the under cover, is excellent in noise prevention effect, and has a sliding type even without the drain hole. Since it can be opened by the minute, there is no problem in oil change.

The structure in which the under cover is of a sliding type is formed by digging a groove in the side surface of the side frame and inserting and locking the under cover in the groove. The form and the number can be changed as appropriate, such as a combination with a roller attached to a cover and rolling in the U-shape of the rail. Also, the fixing means can adopt a structure other than bolting, such as a latch key or a catch, and the position where the fixing means is provided can be freely set. And this invention is applied also to industrial vehicles other than a forklift.

[0010]

According to the first aspect of the present invention, since the bottom opening is closed by the undercover without holes, there is no leakage of engine sound, and the oil is changed in a half-open state because of the slide type, It is possible to perform maintenance with the bottom surface opened by pulling it out and removing it. Further, according to the second aspect of the present invention, the slide plate can be smoothly slid by the rail and the engaging member, and the fixing means does not generate vibration noise or shift during traveling. Further, according to the third aspect of the present invention, the slide plate is hung and supported when the fixing means is released, and does not fall even when the bottom opening is half-opened.
