Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a structure for disposing a balance weight in a cargo handling vehicle such as a forklift truck.

(Prior art)

In a cargo handling vehicle such as a forklift truck, a balance weight is provided at a rear portion of the vehicle in consideration of a vehicle balance when luggage is placed at a front portion.

For example, as shown in FIG. 3, in a forklift truck 9, a balance weight 7 is fixed to a rear portion of the cargo handling vehicle 90. An engine hood 92 provided with a seat 93 is provided at the front of the balance weight 7.

As shown in FIG. 4, the balance weight 7 hooks a hook 71 of the balance weight 7 to an engaging portion 95 provided on the vehicle 90 at the rear of the engine hood 92, and a lower portion thereof is bolted. It is fixed to a bracket 94 of a vehicle 90 by holes 72 and bolts 86.

As shown in FIG. 4, a radiator 81 for cooling the engine cooling water is provided in front of the balance weight 7.
An exhaust muffler 82 and the like are provided. Note that the reference numerals in FIG.
85 is an index stick.

[Problem to be solved]

However, the balance weight 7 must be removed from the vehicle 90 when the radiator 81, the exhaust muffler 82, etc. are to be protected or repaired.

This maintenance service is often performed for the radiator 81. That is, the ventilation part of the radiator is easily clogged with dust and the like, and such clogging lowers the heat radiation efficiency and easily causes the engine to overheat. Therefore, it is necessary to perform regular maintenance.

However, this balance weight 7 is used to improve the vehicle balance when placing and transporting luggage on the fork 901.
Made of heavy iron ingots. Therefore, when removing the balance weight 7, the balance weight must be lifted by a lifting tool such as a hoist.
After the maintenance, the balance weight 7 must be lifted again and fixed by the hooks 71 and the bolts 86. As described above, the conventional balance weight requires a troublesome work such as a lifting tool such as a hoist for removal and installation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a balance weight for a cargo-handling vehicle that does not require a lifting device at the time of maintenance or the like and that can be safely removed.

[Solutions to solve the problem]

The present invention relates to a cargo handling vehicle having a balance weight disposed at a rear portion of a vehicle, wherein the balance weight is rotatable in a substantially horizontal direction to the side of the vehicle, and a radiator or a radiator of a vehicle portion facing the balance weight A balance for a cargo-handling vehicle, wherein an engaging portion provided at a front end of the balance weight is pivotally connected to a rear end of the vehicle by a support pin so that the muffler can be fully opened to the rear of the vehicle. In the weight.

What should be noted in the present invention is that the balance weight is rotatable in a substantially horizontal direction so that the rear of the vehicle can be fully opened. Here, "turnable substantially in the horizontal direction" refers to a state in which it can be opened and closed slightly upward or downward as well as in the complete horizontal direction. In other words, it refers to a state in which the vehicle can be opened and closed in the lateral direction, which is the side of the vehicle. As such a rotatable state, as shown in the embodiment, there is a structure in which a balance weight is pivotally connected to a vehicle in a pin joint type.

[Action and effect]

In the present invention, the balance weight is pivotally attached to the vehicle so as to be rotatable in a substantially horizontal direction. for that reason,
The balance weight is openable and closable in a lateral direction which is a side surface of the vehicle.

Therefore, by rotating the balance weight to the side of the vehicle, the rear portion of the vehicle facing the balance weight is completely opened to the rear of the vehicle. Therefore, when the rear of the vehicle facing the balance weight is to be opened to the rear of the vehicle, such as during maintenance of a radiator in front of the balance weight, simply open the balance weight laterally without removing the balance weight. Is good. Therefore, according to the present invention, it is not necessary to remove the balance weight, so that no hanger is required and the rear part of the vehicle facing the balance weight can be easily and reliably connected to the vehicle only by turning to the side of the vehicle. A balance weight that can be fully opened rearward can be provided.

〔Example〕

The balance weight of the cargo handling vehicle in this example will be described with reference to FIGS.

In this example, the balance weight 1 is disposed behind the forklift truck 9 so as to be rotatable in the horizontal direction. That is, as shown in FIG. 1, a concave plate 61 having engagement pieces 611, 611 is fixed to the forklift truck 9 at the rear left end of the vehicle 90 by welding. Similarly, a concave plate 62 having engaging pieces 621, 621 is fixed to the rear right end of the vehicle 90 by welding. Engagement pieces 611,621 of biconcave plates 61,62
Has pin holes 612 and 621 for inserting pins 21 and 22, respectively, facing the rear of the forklift truck.

On the other hand, the balance weight 1 is made of a heavy iron ingot, and has a convex engaging portion 11 at the front left end and a similar convex engaging portion 12 at the right end. The biconvex engaging portions 11 and 12 have pin holes 111 and 121 for inserting the support pins 21 and 22, respectively.

Thus, the balance weight 1 fits the convex engagement portion 12 on the right side thereof into the concave plate 62 on the vehicle side, and
It is pivoted by 22 (FIG. 1). As shown in FIG. 2, the balance weight 1 is normally closed. At this time, the convex engaging portion 11 on the left side of the balance weight 1 is fitted into the concave plate 61 on the vehicle side, and is supported by the support pin 21. It is fixed so that it cannot be opened. A fixing piece 25 is fixed to the head of the support pin 22 so that it cannot be easily pulled out.

Next, when removing the balance weight 1 for maintenance of parts between the rear of the vehicle and the balance weight, such as the radiator 81 and the muffler 82, the first operation is performed.
As shown in the figure, the left support pin 21 is pulled out, and the balance weight 1 is opened rightward. As a result, the parts are completely opened to the rear of the vehicle (FIG. 1). Therefore, repair of the radiator 81 and the like can be easily performed.

As described above, when opening and closing the balance weight 1, as shown in FIG.
It is preferable to dispose the opening / closing auxiliary tool 3 underneath.
The auxiliary tool 3 has a rotatable roller 31 at the lower part. According to the auxiliary tool 3, the opening / closing operation of the balance weight 1 can be performed smoothly, and the weight balance in the vehicle lateral direction at the time of opening / closing can be maintained by supporting the balance weight 1. Further, it is preferable that the auxiliary tool 3 has a roller and is of a type that can be jacked up.
