Description

[Detailed description of the invention] The present invention relates to a battery case used in a battery forklift truck.It improves workability when replacing batteries, and when a vehicle is equipped with a battery case, the battery case It is an object of the present invention to provide a battery case in which wasted space generated between the top surface of the punch recoverer and the top surface of the punch recoverer is eliminated as much as possible.

Conventionally, the battery replacement work method used for this type of lift was to lift it with a crane or insert a special suspension device into the fork of another forklift and use that device to lift the battery case. The battery case has a shape that allows it to be lifted, that is, a perforated protrusion into which a hook or the like can be inserted is formed at an appropriate location on the top end of the battery case.

Therefore, when replacing the battery, it is necessary to use a crane or special suspension equipment, and if these are in use, it is necessary to wait for them to become vacant, resulting in poor work efficiency.

In addition, the height of the battery case increases due to the height of the protrusion, and when the case is mounted on a vehicle, a wasted space is created between the battery case and the top surface of the battery cover that covers the pantry case. The ground clearance of the top surface of the battery cover is increased by the height of the battery cover, which affects ingress/egress, maneuverability, head guard placement, etc., and when storing the battery case, there should be a protrusion in the forward direction of the case. Because they could not be stacked together and were all placed side by side, a large storage space had to be secured for storage.

The present invention provides a battery case that can solve the above-mentioned drawbacks by equipping the battery case with a hanger that can be retracted.

The second embodiment of the present invention will be described in detail with reference to the drawings.Both side walls 2A of the battery case 20, which is equipped in the battery forklift truck body 1 and has a box-like shape, are opposite to each other.

A pair of pipe-shaped guide tubes 3 are vertically fixed at appropriate height positions on the outer surface of 2B.

A vertical shaft portion 4A of a loop-shaped hanging tool 4 is fitted into the guide tube 3 so as to be able to slide vertically. When equipped and ready for operation, the upper horizontal shaft portion 4B, which has a length slightly wider than the fork width, is the panteri case 2.
The horizontal axis 4B and the lower end horizontal axis portion 4C of the length are located above the bottom wall of the case 2, and when the battery case 2 is lifted, the upper horizontal axis The portion 4B protrudes upward from the old edge of the battery case 2 and has a length such that a hanging device (not shown) such as a fork or hook can be anchored to the protruding portion.

Reference numeral 5 in the figure is a metal fitting for the east side of the hanging tool 4, which is used to maintain the condition when the hanging tool 4 is moved upward as shown in FIG. It is swingably suspended from a protruding bracket 6.

The locking metal fitting 4 may have a hook shape as shown in FIG. 2, or it may be interposed within the guiding tube 3 as shown in FIG. It may be an urging member such as a leaf spring 7 that restricts the vertical movement of 4.

By arranging the hanging tool 4 so that it can move up and down along the wall surface of the battery case 2 in this way, when lifting the case, the upper horizontal axis portion 4B of the hanging tool 4 is moved upwardly from the top edge of the battery case 20. Make it protrude and attach the lower horizontal shaft portion 4C of the hanging tool 4 with the locking metal fitting 5! do.

In this state, the panteri case 2 is lifted by fitting the hook of a crane or the fork of another forklift into the lifting tool 4 and lifting it.

After placing the hoisted case 2 on the body of a forklift, the hook of the crane, etc. is removed from the hoist 4, and the hoist 4 is released from the locking fitting 5, so that the hoist 4 is placed on the side wall of the battery case 2. It is positioned below the edge.

If the restraining means for the hanging tool 4 is a plate spring 7 as shown in FIG. 3, the lifting tool 4 will be forcibly and automatically lowered by the downward rotating force of the bulge cover 8.

By making the hanging device 4 retractable from the upper edge of the battery case 2 in this way, when replacing batteries, which is done almost every day, there is no need for a dedicated hanging device if the crane is in use at the replacement work site. Therefore, it can be immediately transferred to another forklift, eliminating the need to waste time waiting for a crane or special suspension device to open, and also improving work efficiency as there is no need to select a lifting model such as a crane or other forklift. In addition, since there is no protrusion at all on the top surface of the battery case, the battery cases can be stored in a stacked manner, and there is no need to secure a large storage space.

In addition, when mounted on a heavy vehicle, the upper surface of the pad cover 8 that covers the pantry case can be placed with almost no gap to the top edge of the battery case, eliminating wasted space. 8.The ground clearance up to the top surface can be lowered compared to conventional models.

This has various effects that cannot be overlooked, such as ease of getting on and off, stability of running, and safety of the operator's actions due to the wide height space created between the overhead frame portion of the head guard and the driver's seat.

Claims (1)

[Scope of utility model registration request] A pair of cylindrical guide tubes 3 are vertically fixed to the outer surfaces of opposite side walls of a box-shaped case, and a loop shape is formed in the guide tubes, and the pair of upper and lower horizontal shaft portions 4B, 4C is formed with a length slightly wider than the fork width, and a pair of left and right vertical shaft portions 4A connecting the pair of horizontal shaft portions is in a state where the upper horizontal shaft portion 4B interferes with the upper end of the guide cylinder 3. If the lower horizontal shaft portion 4C is located above the lower edge of the case, and the lower horizontal shaft portion interferes with the lower end of the guide cylinder, the upper horizontal shaft portion 4B is located above the upper edge of the case. The vertical shaft portion 4A of the hanging tool 4, which is formed with a length that protrudes and allows insertion of a hanging tool such as a fork, is slidably inserted into the battery case or guide tube, and the hanging tool 4 is inserted into the battery case or guide tube. This battery case for a battery forklift is provided with a locking tool 5.7 for maintaining the state when it is moved upward.
