Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a battery side stopper lock device used in a battery forklift truck that is mounted and driven by a motor operated by a battery.

2. Description of the Related Art Conventional battery side stopper devices include those shown in FIGS. 1 and 2, for example. In this case, battery 1 as a mounted object is mounted on vehicle 2, but! ll Upper body frame 3 and front collar piece 4
At this mounting position, the front stopper piece 4 and the vehicle body frame 3 prevent the battery 1 from moving forward and backward, and movement to the right (in the figure) is prevented by a fixed side stopper piece (not shown). The movement to the left side, which is the battery entrance/exit side, can be stopped by placing the arm-shaped battery side stopper 5 at the solid line position. This battery side stopper 5 has a rotary wheel 6 fixed to its base, and is rotatably supported by a cylindrical bearing 7 having a front stopper piece 4 km attached to the rotary wheel 6. This battery side stopper 5 is shifted to the chain line position when the battery is inserted or removed.

9. As shown in Figure 1s3, the vehicle 2 is driven by a motor 8 operated by the battery 1 mounted at a mounting position.

That is, when the start switch 9 is closed, the relay 10 is turned on, the normally open contact 1 is closed, and power is supplied to the motor 8.

However, in such a conventional battery stopper device, the side stopper 5 has a structure in which the side stop state is maintained by its own weight. There are 6 or 9 problems with the car, such as the risk of it slipping off if it rolls over while driving on a pedestal.

The present invention has been made by focusing on such conventional problems, and is a battery forklift truck that is mounted at a mounting position and runs and is operated by a motor operated by a battery, in which the battery is mounted at the mounting position. A locking rod is provided to lock the rounded side stopper to be held when it is in the battery stop state, a plunger is integrally connected to this locking rod, and a solenoid that electromagnetically drives the granger is connected to a start switch. the motor is connected to the battery via a normally open contact, and a contact is provided that is closed when the locking rod maintains the locked state of the side stopper; Connect in series with a relay that opens and closes the normally open contact,
This series circuit is connected to the battery via the start switch so that power is supplied to the motor and the vehicle runs only when the side stopper is blocked by the locking rod. The purpose is to solve the problems of Yoshijoki.

Hereinafter, the present invention will be explained based on the drawings, and the same parts as those of the conventional device will be given the same reference numerals and the explanation thereof will be omitted.

FIG. 114 to FIG. 6 are diagrams showing an embodiment of the present invention.

Nine brackets 4 are installed at the ends of the front stopper pieces 4.
A side stopper 12 is rotatably mounted on a support shaft 13. A retaining hole 14 is formed in the stock hole (-12), and a through hole 15-I is formed in the puff hole 41.
A locking rod 16 is provided so as to be inserted into the through hole 15, and a granger 17 is integrally connected to the locking rod 16. A solenoid 18 is provided for electromagnetically driving the plunger 1f, and the locking rod 16 is energized when the solenoid 18 is energized.
is designed to protrude and be inserted into and engaged with the retaining hole 14, but is normally retracted by the return spring 19. As shown in FIG. 6, the plunger 17 is integrally provided with a shorting piece, and when the solenoid is energized, the shorting piece is displaced together with the plunger 17, and the contact 4 is closed. It is provided. The contact point M and the relay 10 are connected in series, and this series circuit is connected to the above-mentioned relay 1 via the start switch 9.A relay nt* is connected to the motor 8 and the parallel relay Ij. A normally closed contact is provided in conjunction with this relay ?2, and a warning lamp is connected in series with the normally closed contact.This series circuit is connected to are doing.

Next, the action will be explained.

In FIG. 5, when the side stopper <-12 is at the solid line position protruding to the side of the mounting position, the side stopper 12 prevents the battery 1 from moving laterally and is in the nine-side stop state. When the start switch 9 is closed in an attempt to run or operate the vehicle 2 in this state, the solenoid 18 is energized as shown by the two-dot chain line in FIG. Insert and engage the matching hole 14 to lock the side stock horn.

At the same time, the short-circuiting circuit short-circuits the contact 21 and relay 10
Power is supplied from the battery 1 to close the normally open contact 11. Therefore, the motor 8 is operated and the vehicle 2 is driven or operated. On the other hand, #I-n is also energized to open a normally closed contactor and cut off the power supply to the warning lamp so that no warning is issued. Thus, in this condition, suddenly brake,
! The side stopper hooks will not come off even if you receive a shock from a L start or a sudden turn.

On the other hand, when the side stopper 12 is in the released state where the side stopper 12 is retracted from the side of the mounting position lid as shown by the two-dot chain line in Figure 5, the battery 1 can be removed from the mounting position and replaced. It has become. At this time, if the start switch 9 is closed to start the vehicle 2, the solenoid 18 is energized 11K, and the plunger 1
Although the locking rod 16 tries to come out to the center through 7t, the short-circuiting piece is in contact with the side stopper 12 by 4m and does not short-circuit the contact 4.

Therefore, the relay lO is not energized and the normally open contact 1] is opened, and the motor 8 is not supplied with power at 911, and the vehicle 2 does not run. At the same time, the relay 4 is not energized, the normally closed contact remains closed, and the warning lamp lights up. Therefore, the warning lamp warns that the strapper is not in the locked state, and the vehicle 20 is not driven.
This encourages re-inspection and prevents forgetting to tighten the side stopper.

Same, this invention number 1! In the example, the above-mentioned warning lamp is used to give a warning, but instead of this, Puzuichi et al.04
You may also use this to issue a warning.

As described above, 1. According to the present invention, the configuration is such that the battery is driven and operated by the motor operated by the battery mounted at the mounting position.
), a round locking rod is provided to lock the side stopper for holding the battery in the mounting position when the battery is in the battery stop state, and a plunger is integrally coupled to the locking rod; A solenoid for electromagnetically driving the plunger is connected to the battery via a start switch, the motor is connected to the battery via a normally open contact, and the locking rod maintains the side stopper in a locked state. Provide a contact that closes when the engine is hot, connect a relay in series with the contact to open and close the normally open contact, and connect this series circuit to the battery via the start switch. When suddenly starting or making a sharp turn, the side stopper will not come off, and the vehicle will only be able to move when the side stopper is in the locked state. Therefore, forgetting to engage the side stopper is completely prevented. This has the effect of improving safety.
