SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and a slider for transmitting a pull-out force of a tray-side lever device mounted on a battery loading tray is provided on an operation side. The lever device is connected to the lever device by a wire cable in the pulling direction.The slider is further provided with a spring urged in the opposite direction to the pulling direction, and the slider is provided with a pull-out pin. One end of a lever fixed to a vehicle body is attached, and the lever is rotatable around a fulcrum, thereby providing a battery withdrawing device for a reach-type forklift.

With this configuration, when the operation side lever device is operated to fix and open the battery tray, the slider of the tray side lever device connected to the operation side lever and the wire cable is moved by a predetermined stroke while opposing the force of the spring. . For this reason, the lever whose one end is rotatably fixed to the slider rotates around the fulcrum and opens the hook-shaped part hooked on the fixing pin on the vehicle body side to open the tray and releases the fixing of the tray. At the same time, the position of the pin attached to the slider moves, and the pin comes into contact with the mast-side tray push dog that advances by the mast's reach stroke. A withdrawal is performed.

The operation side lever device and the tray side lever device are always connected by the wire cable even when the tray on which the battery is loaded is moved by a fixed distance and the tray is pulled out. A failure state such as a malfunction on the side can be easily detected and confirmed from the operation side.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described.
This will be described with reference to the drawings. FIG. 1 is a view of the tray-side lever device of the present invention viewed from the lower surface of the tray, FIG. 2 is a Z view shown in FIG. 1, and FIG. 3 is a system for explaining the entire configuration of the drawer of the present invention. FIG. 4 is a top view of the battery tray, and FIG. 5 is a drawing showing the operation side lever device.

As can be seen from the system diagram of FIG. 3, the overall structure of the battery pull-out device of the present invention includes an operation-side lever device 10 provided at the driver's seat of a reach-type forklift and operated by an operator, and a battery. It comprises a tray side lever device 20 attached to the lower surface of the tray 1 and a wire cable 2 connecting the two lever devices.

In the operating side lever device 10, a rod 12 having a handle 11 is connected to one end of the wire cable 2, and the operator pulls up or pushes down the handle 11 from the driver's seat to pull the wire cable 2 down. It can be pulled and returned, and a control sensor (not shown) that can detect the position of the rod 12 is provided.

The other end of the wire cable 2 is pulled down from the driver's seat to the lower surface of the tray 1 on which the battery is loaded, is taken into the position where the tray side lever device 20 is attached, and is connected to the slider 24. The slider 24 performs a central function of the operation of the tray-side lever device 20, and its moving stroke is determined by releasing the lever 21 from the vehicle-body-side fixing pin 4 and moving the pin 25 against the pushing dog 3 that is moved by the mast reach operation. It plays two important roles: positioning.

The battery is reloaded on the tray 1 and the tray 1 is returned to the fixed position on the vehicle body by the mast reach operation, and the wire cable 2 is connected to the operation side lever device 1.
The slider 24 returns to the fixed position by the action of the return force of the spring 26,
1 holds the vehicle body side fixing pin 4.

In FIG. 1, a slider 24 is slidably guided left and right by two guides 31. At the end of the slider 24, there is provided a plate 32 integrally attached, one end of the wire cable 2 is connected, and the spring 24 resists the force of the wire cable 2 in the pulling direction by the spring 26 so that the slider 24 is moved to the left side. Positioned to fixed position.

A pin 25 for transmitting a pull-out force is implanted in the slider 24. One end of the lever 21 has an elongated hole and a pin connected to the slider 24 so that the lever 21 can rotate about the fulcrum 22. Depending on the consolidation method, such as
The slider 24 is mounted so that the movement stroke of the slider 24 can be transmitted. The other end of the lever 21 is formed in a hook shape so as to be engaged with a fixing pin 4 (not shown in FIG. 1) on the vehicle body side. When the slider 24 is positioned at the left end, the other end of the lever 21 is on the vehicle body side. It is connected at a position where it holds and locks the fixing pin 4.

To explain the operation function, the operator pulls up the handle 11 of the operation side lever device 10 shown in FIG. 5 from the driver's seat to pull out the battery tray, and moves the tray from the tray fixed position to the tray opening direction. Then, the stroke of the wire cable 2 connected to the rod 12 is transmitted to the slider 24 of the tray-side lever device 20 shown in FIG.

As a result, the slider 24 moves the spring 2 by the stroke of the wire cable 2 in the pulling direction.
6, the pin 25 moves from the position A to the position B. Naturally, the connecting portion of the lever 21 also moves, and the hook of the lever 21 rotates in a direction to release the locked vehicle body side fixing pin 4 (not shown in FIG. 1). In this state, the fixing of the tray 1 to the vehicle body is released.

The push dog 3 (not shown in FIG. 1), which is moved by the reach operation of the mast, strokes a predetermined distance and then pushes the pin 25 located on the movement line. To the battery replacement position.

When the battery is replaced and the loaded tray 1 is stored, the cushion knob provided on the tray 1 is pushed by returning the mast reach operation, and the tray 1 is pushed back to the fixed position of the vehicle body. . At this time, even if the back portion of the hook of the lever 21 of the tray side lever device 20 may hit the vehicle body side fixing pin 4,
It has a shape that can be released.
