Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery check and maintenance work for a forklift.

[0002]

2. Description of the Related Art In the prior art, as shown in FIG. 5, a battery is placed on a rotating roller such as a bearing, and an operator manually slides the battery laterally to pull it out or pull it in.

[0003]

However, in the above-mentioned conventional structure, in addition to the work of fixing and unlocking the battery, a heavy load is imposed on the operator, which causes an increase in battery replacement time and an increase in operator fatigue. It was It is an object of this invention to eliminate such problems.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems.
The invention described is to attach a band-shaped member having a plurality of protrusions to the bottom surface of the battery case or tray of the forklift,
A belt- or chain-shaped moving band having a large number of protrusions capable of engaging with and engaging with the band-shaped member is arranged so as to be driven by a rotary drive unit using a manual handle or a motor, and is attached to a manual stand. The feature is a battery lateral pull-out device.

With the above-mentioned structure, the manual stand is brought into the bottom of the battery case or tray, the belt or chain-like end of the movable band of the battery lateral pull-out device is inserted, and the handpiece is lifted and raised. By engaging and driving the protrusions on the belt and the moving belt, the battery can be pulled out and pulled in easily, reducing the man-hours for battery replacement and saving labor, and simplifying the vehicle-side structure to improve reliability. Can contribute.

According to a second aspect of the present invention, in the horizontal battery withdrawing device according to the first aspect, the push rod provided on the manual stand side releases the lock pin attached to the bottom surface of the battery case or tray. It is supposed to be.

With this structure, the battery can be fixed to the vehicle body and unlocked by simply bringing in the manual stand, and the dismounting work can be prepared to further reduce the number of battery replacement steps and save labor. .

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below.
It will be described with reference to the drawings. FIG. 1 is a side view of a manual stand to which the lateral battery pull-out device according to the present invention is attached, and FIG.
Is a rear view of the battery case housed in the vehicle, and FIG. 4 is a side view of the battery case.

The manual stand 7 shown in FIG. 1 is a stand having a general easy-to-move lift function used for vehicle maintenance, and is equipped with the lateral battery withdrawing device according to the present invention. In the figure, the movable band 5 has an endless belt or chain shape implanted in the protrusion 4, and is arranged horizontally in the front-rear direction of the manual stand 7.

A guide wheel for the moving belt 5 is provided at the tip end,
A drive wheel is provided at the rear end portion, and the drive force is electrically driven from the rotary drive unit 6 to the moving zone 5 by using a reduction gear or a belt.

When the rotary drive unit 6 is operated by the manual handle, it is sufficient to decelerate the operating force of the operator to within about 5 kg so that the battery can be moved in that state. When the motor is used, the battery to be installed or removed is used by setting it to match the battery voltage of the vehicle.

The bottom view of the battery case of FIG. 2 shows one embodiment of a battery lock mechanism for fixing the battery case 1 or the tray 2 carrying the battery to the vehicle body of the vehicle.

That is, in addition to the belt-shaped member 3 provided with a protrusion capable of engaging with and engaging with the protrusion 4, the slide bush and the bearing for assisting the movement of pulling out and pulling in the battery, the battery lock lever 9 and the lock are locked. The pin 11 is provided and locked.

When pushing the horizontal battery drawer shown in FIG. 1 into the lower surface of the battery case 1 or tray 2,
The tip end of the push rod 8 attached to the side surface of the battery lateral pull-out device pushes the battery lock lever 9 to release the engagement state with the lock pin 11, so that the belt-shaped member 3 and the protrusion 4 are engaged with each other. At this time, the battery is ready to be pulled out, and when the manual stand 7 is pulled back after being pulled in, the battery is locked and fixed.

In the rear view of the battery case housed in the vehicle of FIG. 3, the pushing position of the moving band 5 is shown by an imaginary line, and in the side view of the battery case of FIG. 4, the positions of the moving band 5 and the push rod 8 are shown. It is shown in phantom.

The use of the lateral battery withdrawing device of the present invention facilitates the withdrawal and withdrawal work of the battery, which reduces the number of battery replacement steps and saves labor.
The structure on the vehicle side can be simplified and the reliability can be improved. In a vehicle provided with a battery lock mechanism, the lock can be released by pushing the manual stand 7 into a predetermined position, which facilitates battery removal work, greatly reducing the battery replacement man-hour and labor saving of the operator. It will be.
