Description

[Detailed Description of the Invention] The present invention relates to a head guard for a forklift truck.

Generally, a forklift truck has a front protector erected on the upper surface of the front part of the vehicle body, a balance weight 17 attached to the rear end of the vehicle body, and an engine, a clutch, The engine frame E2 is equipped with various devices such as a transmission, and the driver's cab is equipped with a head guard with a top wall to protect the driver from falling objects.
-I am.

Conventional Herad Guards are broadly divided into fixed types that are integrated with the car body, and tilt type types that can be rotated to the front or sides of the car body1. When taking things on and off,
The top wall becomes an obstacle, making it impossible to lift heavy objects upwards or lower them from above U-, and moving heavy objects laterally within the Rudguard. Since it is necessary to remove the engine hood, it is extremely difficult to install and remove it, and when repairing or inspecting parts in the engine compartment, it is necessary to remove the engine hood, which is a hassle.

On the other hand, in the latter case, the front protector, engine hood, etc. are integrally constructed, and the upper part of the engine compartment can be opened by rotating.
The opening angle of the mast is limited by the mast, and by suppressing vehicle instability due to unbalanced loads and protruding into the passageway for items that rotate sideways. Repair of these inaccessible parts,
Inspection and other tasks are difficult to perform, and in order to reduce the rotational load, a relatively large and complicated torsion bar device is required, and adjustment of this device requires excessive labor and time. However, there are drawbacks such as not only significantly lowering the assembly efficiency but also increasing costs.

The present invention aims to eliminate the above-mentioned drawbacks and provides a head guard that includes an engine hood and is configured to be slidable in the longitudinal direction of the vehicle body.

Next, embodiments of the present invention will be specifically described with reference to the drawings.

In FIG. 1, 1 is a front protector installed upright on the front upper surface of the vehicle body 2, 3 is a balance weight attached to the rear end of the vehicle body 2, and 4 is a front protector provided at the rear of the front protector 1. This is the driver's cab.

An engine room 5 in which various devices (not shown) such as an engine, a clutch, and a transmission are installed is formed in the lower part of the driver's cab 4. The partial buttons leading to the front opening of the hood 11 and the upper rear portion of the engine room 5 are covered by a toe board 6 and an engine hood 11, which will be described later.

Additionally, L-shaped horizontal guide members 7 extending over substantially the entire length of the vehicle body 2 are symmetrically disposed at the upper portions of both sides of the vehicle body 2.

The driver's cab 4 is equipped with a head guard 9.

The head guard 9 (ri) includes four pillars 10a erected at the corners of the driver's cab 4, a top wall 10b whose corners are fixed to the upper ends of the pillars 10a, and lower ends of the front and rear pillars 10a. The frame body 10 is formed from a pair of left and right connecting members 10c, and the front and rear parts are open, and the frame body 10 is provided spanning from the upper rear part of the engine room 5 to the upper part of the front end of the balance weight 3. Both sides of the engine hood 11 are fixed to the connecting member 10ch of the frame 10 and the inner side of the rear strut 10a, and three sets of buttons are attached to the front and rear end buttons of the connecting member 10c and toward the rear in the middle. A roller 12 is installed.

The roller 12 is connected to the connecting member 10 as shown in FIG.
It is rotatably fitted to a pin 13 fixed to the connecting member 10c, and both end surfaces are regulated by the inner wall of the connecting member 10c, and its lower end slightly protrudes from the lower surface of the connecting member 10c, and the horizontal guide member 7 is engaged.

Next, the operation of the device having the above configuration will be explained.

When repairing or inspecting parts such as the engine disposed at the rear of the engine room 5, the bolts 15 fastened to the sides of the front protector 1 and the balance weight 3 are loosened and removed.

After that, when the head guard 9 is pushed backward, the roller 12 provided at the bottom of the head guard 9 moves on the upper surface of the horizontal guide member 7, whose movement in the left and right direction is restricted by the shoulder 7a of the horizontal guide member 7. The head guard 9Lli moves easily and reaches position A shown by the two-dot chain line in FIG.

By moving the head guard 9 rearward, the engine hood 11, whose front and rear sides are opened, simultaneously moves from the upper rear position of the engine room 5 to the upper position of the balance weight 3 without any hindrance. engine room 5
The rear upper part is open.

When the head guard 9 is in the retracted position, the roller 12 provided at the rear end of the head guard 9 is removed from the rear end of the horizontal guide member 7, and the two sets of rollers 12 in front of the head guard 9 are removed from the rear end of the horizontal guide member 7. The company is supported without changing its stance.

It goes without saying that the intermediate roller 12 is disposed at a rearward position outside the center of gravity of the helad guard 9 in order to maintain such a stable posture.

As described above, when the head guard 9 is retreated, the upper part of the engine room 5 is partially opened, but the toe board 6 that covers the front part of the engine hood 11 is removed from the vehicle body.
When removed from the engine compartment, the upper part of the engine room 5 is completely opened, and work such as repair and inspection of parts can be carried out in its entirety.

Moreover, when a heavy object such as an engine is to be attached or detached, the herad guard 9 may be further retreated from the above-mentioned position A.

That is, as shown by the two-dot chain line in FIG. 1, the herad guard 9 is retreated from the upper part of the engine room 5 to position B, where it is completely retracted, and the rear end is attached to the hand-held cradle 17. If the engine room 5 is supported by the engine room 5, the upper part of the engine room 5 will be completely opened, making it easier to attach and detach the heavy items.

As is clear from the above, the head guard according to the present invention is
Rollers are installed at the bottom of the vehicle body to engage with horizontal guide members that extend along almost the entire length of the vehicle body on both sides of the vehicle body. Since the engine hood, which extends from the upper rear part to the upper part of the front end of the balance weight, is fixed and movable in the longitudinal direction with respect to the vehicle body, according to the present invention, by the movement of the herad guard, The upper part of the engine room can be easily opened, and in some cases, it can be opened completely, allowing parts to be repaired, inspected, etc.
Work such as attachment and detachment becomes easier and has the effect of significantly improving the efficiency of the work.

In addition, since the head guard runs on rollers, there is no labor burden when moving it, and there is no need for a torsion bar device, etc. found in conventional tilt systems, making the structure simple and extremely practical. It is something like that.
