Description

  The present invention relates to a battery stopper device for an industrial vehicle on which a battery is mounted.

  Some industrial vehicles are equipped with a battery as a power source for electrical equipment. In this type of industrial vehicle, for example, a battery housing chamber for housing the battery in a body frame is provided. Now, while the industrial vehicle is traveling, vibrations, inertial forces, etc. act on the battery, so it is conceivable that the battery will move in the battery storage chamber. Therefore, a battery stopper device is used to restrict the movement of the battery stored in the battery storage chamber.

Conventionally, as a battery stopper device, for example, as described in the following patent document, a locking member provided on the battery inlet / outlet side is moved up and down to engage with a locked member provided in a battery storage chamber. A battery that restricts the movement of the battery toward the carry-in / out entrance side is employed.
Japanese Utility Model Publication No. 63-70660 Japanese Utility Model Publication No. 3-71926

  However, in a battery stopper device having a structure in which the locking member is moved up and down, when the vehicle body frame vibrates in the vertical direction due to a step on the road surface, the locking member jumps upward and disengages from the locked member, thereby moving the battery. It may be impossible to regulate. In particular, when a roller for facilitating the insertion and removal of the battery is provided in the battery storage chamber, the battery can be moved with a relatively small force. It can lead to a big move.

  This invention is proposed based on such a situation, Comprising: It aims at enabling it to control more reliably the movement of the battery accommodated in the battery storage chamber.

  In order to achieve the above-mentioned object, the present invention provides a battery storage chamber provided in a vehicle body frame and having a carry-in / out opening opened to the side, and a battery inserted into and removed from the carry-in / out port in the battery storage chamber. In the battery stopper device for an industrial vehicle that restricts movement, the battery storage chamber is detachably attached in an up-and-down direction to an engagement portion located closer to the carry-out entrance than the stored battery. A lateral movement stopper engaged with a part to prevent lateral movement of the battery to the carry-in / out side, and covering the carry-out / inlet from outside the lateral movement stopper engaged with the engagement part; and A cover attached to be openable and closable between a closed position where it cannot move relative to the battery storage chamber and an open position where the carry-in / out port is fully opened. A vertical movement stopper that is provided on the cover so as to face the battery storage chamber when the cover is in the closed position, and that prevents the vertical movement of the horizontal movement stopper in contact with the horizontal movement stopper; It is set as the structure provided with.

  According to this configuration, the lateral movement of the battery is blocked by the lateral movement stopper engaged with the engaging portion, and the vertical movement of the lateral movement stopper in the vertical direction is directed to the battery storage chamber with the cover as the open position. It is blocked by the vertical movement stopper. Therefore, for example, even when the vehicle body frame vibrates in the vertical direction, the lateral movement stopper does not come off from the engagement portion, and the lateral movement of the battery toward the carry-in / out side can be reliably prevented. Since the vertical movement of the lateral movement stopper in the vertical direction is not prevented when the cover is in the open position, the lateral movement stopper can be detached from the engagement portion, and the carry-in / out opening is completely opened. The battery can be exchanged and maintained by inserting / removing the battery from / into the battery storage room through the carry-in / out port.

  In the present invention, the lateral movement stopper is engaged with an engagement portion formed on the floor member of the battery storage chamber from above, and the vertical movement stopper is located when the cover is in the closed position. In addition, it may be configured to project toward the battery storage chamber above the lateral movement stopper engaged with the engagement portion.

  In this way, even if the lateral movement stopper moves vertically upward and tries to disengage from the engagement site, the longitudinal movement is prevented when it comes into contact with the longitudinal movement stopper above the lateral movement stopper. It is possible to prevent the vertical movement stopper from being detached from the engagement site. The engaging portion can be, for example, an engaging hole formed in the floor member of the battery storage chamber in the vertical direction, and a lateral movement stopper is inserted into the engaging hole from above and engaged. Can be.

  According to the present invention, when the lateral movement stopper is engaged with the engaging portion, the lateral movement stopper prevents lateral movement of the battery toward the loading / unloading side, and further, when the cover is opened, the lateral movement is performed by the vertical movement stopper. Since the stopper is prevented from detaching from the engagement portion, the lateral movement of the battery toward the loading / unloading side can be reliably prevented.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments in which the present invention is applied to a battery-type forklift in which a battery is horizontally taken in and out in the vehicle width direction will be described below in detail with reference to the drawings.

  As shown in FIG. 1, the battery-type forklift according to the present embodiment (hereinafter simply referred to as a forklift) has a battery storage chamber 3 for storing a battery 2 at a position below a driver's seat of a vehicle body frame 1. Thus, the battery storage chamber 3 is opened toward the right side, and this opening portion serves as a carry-in / out port 4. The battery 2 is inserted into and removed from the carry-in / out port 4 in and out of the battery storage chamber 3 horizontally in the vehicle width direction of the forklift, that is, in the left-right direction. Further, as shown in FIG. 2, the floor member of the battery storage chamber 3 is provided with a roller 5 that is pivotally supported in the front-rear direction of the forklift and freely rotates in the direction in which the battery 2 is inserted and removed. The battery 2 can be easily inserted and removed.

  Further, as shown in FIGS. 2 and 3, the floor member of the battery storage chamber 3 has a predetermined depth D in the vertical direction at a position closer to the loading / unloading port 4 than the battery 2 stored in the battery storage chamber 3. Are provided with bottomed engagement holes 7a and 7b, and the lateral movement stopper 6 is engaged with the engagement holes 7a and 7b. The lateral movement stopper 6 includes an engagement member formed in a substantially U shape in a side view and an abutting member fixed to the battery 2 side of the engagement member, and both end portions 8a of the engagement member. , 8b (hereinafter referred to as engagement end portions 8a, 8b) are inserted into the engagement holes 7a, 7b from above and engaged therewith. Here, the diameters of the engagement holes 7a and 7b are slightly larger than the diameters of the engagement ends 8a and 8b, so that the engagement ends 8a and 8b can be inserted into and removed from the engagement holes 7a and 7b. Has been made. That is, the lateral movement stopper 6 inserts the engagement end portions 8a and 8b into the engagement holes 7a and 7b from above and engages them, and pulls the engagement end portions 8a and 8b upward from the engagement holes 7a and 7b. Can be removed.

  When the lateral movement stopper 6 is engaged with the engagement holes 7a and 7b, even if the inertia force in the direction of the loading / unloading port 4 acts on the battery 2 during traveling of the forklift and the battery 2 moves laterally, the battery 2 does not move laterally. At the time of contact with the contact member 6, the lateral movement is prevented. The material of the lateral movement stopper 6 may be any material that can withstand the lateral load applied from the battery 2 when the battery 2 abuts against the lateral movement stopper 6, and as shown in FIG. As shown, a buffer member 9 made of rubber or foam material may be provided on the battery 2 side surface of the contact member.

  On the other hand, a cover 11 that can be opened and closed is provided on the right side of the body frame 1. One end of the cover 11 is fixed to a hinge 10 having a vertical axis that is fixed to the vehicle body frame 1 in front of the front edge of the carry-in / out entrance 4, and the cover 11 is around the axis of the hinge 10. It can be opened and closed by turning it horizontally.

  When the cover 11 is turned backward, the cover 11 covers the lower half of the carry-in / out port 4 from the outside of the lateral movement stopper 6, and here the other end of the cover 11 (the end fixed to the hinge 10). The cover 11 cannot be turned, and the cover 11 cannot be moved at all with respect to the body frame 1. The cover 11 is locked by a locking device (not shown) fixed to the body frame 1. The position of the cover 11 at this time is the closed position in the present invention. Further, since the battery storage chamber 3 is a part of the vehicle body frame 1 and naturally the battery storage chamber 3 cannot move with respect to the vehicle body frame 1, when the cover 11 is locked in the closed position, the cover 11 is stored in the battery storage frame 3. It is impossible for the chamber 3 to move. When the lock by the locking device is released and the cover 11 is swung forward from the closed position, the lower half of the carry-in / out port 4 is not covered by the cover 11 and the carry-in / out port 4 is fully opened to the right. It becomes a state. The position of the cover 11 at this time is an open position in the present invention.

  A vertical movement stopper 12 protrudes from one side of the cover 11, and the vertical movement stopper 12 is more than the horizontal movement stopper 6 engaged with the engagement holes 7 a and 7 b when the cover 11 is in the closed position. Is also provided so as to protrude upward into the battery storage chamber 3. As shown in FIG. 3, when the cover 11 is in the closed position, the distance L from the lower end of the vertical movement stopper 12 to the upper end of the horizontal movement stopper 6 is from the upper end of the engagement hole 7a (7b) to the engagement hole 7a. The vertical movement stopper 12 is arranged so as to be smaller than the distance to the lower end of the engaging end 8a (8b) inserted in (7b) (equal to the depth D of the engaging hole 7a in the state shown in the figure). The upper end of the horizontal movement stopper 6 is in contact with the lower surface of the vertical movement stopper 12.

  That is, when the lateral movement stopper 6 engaged with the engagement holes 7a and 7b is to be moved vertically upward while the cover 11 is locked at the closed position, the cover 11 and the vertical movement stopper provided thereon are arranged. Since 12 cannot move up and down, the vertical movement is blocked when the vertical movement is made until the upper end of the horizontal movement stopper 6 contacts the lower surface of the vertical movement stopper 12. At this time, the engagement end portion 8a (8b) is still inserted into the engagement hole 7a (7b) by the length obtained by subtracting the distance L from the depth D, and the lateral movement stopper 6 is engaged with the engagement hole 7a. , 7b is kept engaged.

  Therefore, if the lateral movement stopper 6 is engaged with the engagement holes 7a and 7b and the cover 11 is locked by the locking device in the closed position, the vehicle body frame 1 vibrates in the vertical direction and the lateral movement stopper 6 moves vertically. However, since the lateral movement stopper 6 can be kept engaged with the engagement holes 7a and 7b without being disengaged from the engagement holes 7a and 7b, the lateral movement stopper 6 ensures the lateral movement of the battery 2. Can be blocked.

  On the other hand, in the state where the cover 11 is in the open position, even if the lateral movement stopper 6 engaged with the engagement holes 7a and 7b is longitudinally moved upward, the vertical movement is not prevented, The lateral movement stopper 6 can be moved vertically upward by D or more, and thus the lateral movement stopper 6 can be detached from the engagement holes 7a and 7b.

  Therefore, when the lock is released and the cover 11 is set to the open position to open the carry-in / out port 4, and the lateral movement stopper 6 is moved vertically upward to be disengaged from the engagement holes 7 a and 7 b, the carry-in / out port 4. The battery 2 can be taken in and out.

  In the above embodiment, the configuration in which the battery storage chamber 3 is opened to the right side and the carry-in / out port 4 is provided has been described. However, the carry-in / out port is provided on the other side of the battery storage chamber 3 and the carry-in / out port is provided. Of course, it is good also as a structure provided with a battery stopper apparatus. Further, in the above-described embodiment, the configuration including the cover 11 that is horizontally opened and closed is described. However, the cover opening / closing direction may be another direction such as the vertical direction, and the cover may be a vehicle body. It may be separated from the frame 1 to be in the open position.
