Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a forklift battery replacement aid which is convenient when a battery mounted on a forklift is replaced by another forklift.

[0002]

2. Description of the Related Art A battery which is a power source of a battery forklift is normally charged while mounted on the forklift. However, since charging takes time, when the operating rate is high, the discharged empty battery is replaced with a spare battery that has been charged in advance, and the empty battery is charged by predetermined charging equipment and stored as a spare battery.

[0003] When replacing the battery of the standard type forklift 1, as shown in FIG. 5, a hanging tool 4 of an overhead crane is engaged with a hole 3 provided on the upper side of the battery case 2, and the battery case 2 is lifted and replaced. However, when there is no such equipment as an overhead crane, an insertion port 7 is provided at the lower side of the battery case 6 as shown in FIG. 6, and a fork 23 of another forklift is inserted into the insertion port 7. A so-called lower plug-in type forklift 5 that lifts and replaces the battery case 6 is used.

[0004]

In the lower plug-in type forklift 5 described above, the plug-in 7 for inserting a fork is provided at the lower side of the battery case 6, so that the height is increased by the height of the plug-in 7. A dedicated battery case 6 is mounted.
The battery case 6 is not compatible with the battery case 2 and cannot be mounted on the standard forklift 1. Therefore, when the lower forklift 5 and the standard forklift 1 are owned, a spare battery must be prepared for each forklift, which is disadvantageous in terms of cost and maintenance.

[0005] The present invention provides a battery replacement aid which allows a standard forklift battery to be mounted on a lower plug-in type forklift without modification.

[0006]

SUMMARY OF THE INVENTION A battery replacement assisting device according to the present invention is a battery replacement assisting device of a forklift, wherein a plate-like member which can be fitted to a bottom surface of a battery case and a cylindrical member into which a fork can be inserted. Wherein the tubular member is fixed to the bottom surface of the plate member so as to be detachable from the battery case.

[0007] The cylindrical member does not specify a means for enabling the fork to be inserted. For example, instead of the cylindrical member, a U-shaped member fixed to the bottom surface of the plate-shaped member in a U-shape or an inverted U-shape may be considered.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, a lower plug-in forklift 5 has a fork 12
And a mast 13 for raising and lowering the fork 12, a weight 14 at the rear of the vehicle body, and a head guard 1 for protecting the driver.
5 is provided.

FIG. 2 shows a battery as a power source. The battery case 2 is the same as that mounted on the standard type forklift 1, has a box shape with an open top, and has a bottom plate 16 raised as shown in FIG. The battery replacement aid 17 includes a plate-shaped member 18 that can be fitted into the raised portion of the battery case 2 and a U-shaped member 19 into which a fork can be inserted and which has a length in the left-right direction of the plate-shaped member 18. The U-shaped member 19 is provided on the bottom of the
This is fixed in parallel. The battery case 2 is placed on the battery replacement aid 17, and is positioned by fitting the plate-shaped member 18 to the bottom raised portion, and is mounted on the battery storage portion formed by the frame member of the lower plug-in forklift 5.

The upper surface of the battery case 2 is closed by a battery cover 20, and the rear end of the battery cover 20 is supported by a hinge (not shown) so as to be openable and closable on the vehicle body, and the front end of the battery case 2 is stopped by a stopper 21. Fixed to

To replace the battery of the lower plug-in type forklift 5, the battery cover 20 is opened as shown in FIG.
The battery can be removed. Then, a fork 23 of another forklift is inserted into the insertion opening 22 of the battery replacement aid 17, and the discharged empty battery is taken out of the vehicle body, and the charged battery is mounted on the vehicle body in the reverse procedure.

The battery of the lower plug-in type forklift 5 can be mounted on the standard type forklift 1 by removing the battery replacement aid 17.

[0013]

According to the present invention, a standard forklift 1 is provided.
And the battery of the lower plug-in type forklift 5 can be shared, so that it is not necessary to manage the battery for each forklift, which is advantageous in terms of cost and maintenance. In addition, since the battery replacement auxiliary tool has a very simple structure and a standard battery case, an inexpensive battery case for a lower plug-in type forklift can be provided.
