Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reach-type forklift, and particularly to a reach-type forklift that allows easy and reliable battery replacement.

Examples of conventional reach type forklifts include those shown in FIGS. 1 to 4 (see Japanese Utility Model Application No. 55-167996). That is, a storage section 2 is provided in the vehicle body 1, and a battery 3 is stored in the storage section 2 in a replaceable manner. Batsuteri 3
A roller 5 that rolls on the frame 4 is provided at the bottom of the frame 4, and the battery 3 is connected to the mast 6 which is movable in the longitudinal direction of the vehicle body 1 by means of a reach cylinder (not shown), and the battery 3 is connected to the mast 6 by means of a linkage 7. I have made it possible to connect. This linking tool 7 has a fulcrum 8 on the battery 3 side, and a hook portion 1 at the tip of a pin 9 protruding from the side of the mast 6 (specifically, the outer mast).
0 can be freely engaged and disengaged [Fig. 2]. When the voltage of the battery 3 drops and you want to replace it with a new battery, use a reach cylinder (not shown) to move the mast 6 toward the storage section 2, bring the mast 6 close to just in front of the battery 3, and place the tip of the linking tool 7 on the pin 9. Engage the hook part 10 [Fig. 3], and then reversely move the mast 6 forward using the reach cylinder [not shown].
The battery 3 is pulled out from the storage part 2 by the mast 6 (FIG. 4), replaced with a new battery, and the same operation as above is performed again to store the new battery in the storage part 2. After being stored, the battery 3 is locked to the vehicle body 1 separately in both the longitudinal direction and the lateral direction of the vehicle body by appropriate stoppers (not shown). In the figure, 11 is a head guard, 12 is a steering wheel, and 13 is a head guard.
indicates a tire, and 14 indicates a fork.

However, in the case of such conventional reach type forklifts, the battery 3 is replaced by using the forward and backward movement of the mast 6 and via the linking device 7, so the battery 3 is replaced and the cargo is not transported. If you forget to remove the linkage 7 when restarting work, or forget to remove the stopper before replacing the battery 3, and move the mast 6 forward, the thrust of the reach cylinder will be too strong for cargo handling and transportation. There is also the problem that either the linking tool 7 or the stopper may be damaged due to the fact that it is made into an object. Moreover, battery 3 is originally replaced when the voltage of battery 3 drops and the remaining capacity is low, but in order to replace it with a new battery, a battery with low remaining capacity whose voltage has dropped is used. It is unreasonable to have to do this, and there is also the problem that the battery 3 cannot be replaced if there is a failure in the reach cylinder or other hydraulic equipment. Further, in order to safely store the battery 3 within the storage section 2, it is necessary to provide stoppers for preventing movement of the battery 3 in both the longitudinal direction and the lateral direction of the vehicle body 1.

This invention was made by focusing on such conventional reach-type forklifts, and employs a manual lever or manual lever to easily and reliably move the battery back and forth when replacing the battery. The manual lever can also be used as a battery movement stopper, so that the battery can be held safely and securely in the storage area when the battery is not being replaced (during normal use of the forklift), thereby solving the previous problem. It is intended to.

The details of this invention will be explained below based on the drawings. FIG. 5 to FIG. 11 are diagrams showing an embodiment of the present invention. In the following description, parts that are the same or similar to those in the prior art will be denoted by the same reference numerals and redundant explanation will be omitted. Reference numeral 20 denotes a trolley, which is placed in the storage section 2 of the vehicle body 1 for placing the battery 3 and is movable in the front-rear direction of the vehicle body 1 (the left-right direction in FIG. 5). Therefore, the trolley 20 has wheels 21 that can roll freely on the frame 4.
There is a pair of these on each side. Reference numeral 22 designates a pin receiving portion, which has a U-shape and is provided on the front side of the truck 20 so as to be able to receive an engagement pin 24 of a manual lever lever 23, which will be described later. The battery 3 placed on the truck 20 is prevented from falling off from the truck 20 by working together with the raised projections 25.

The manual lever lever 23 is battery 3 together with the trolley 20.
In order to move the unit back and forth and also serve as a "moving stopper," it is rotatably provided at a portion corresponding to the side of the carriage 20 and battery 3 of the storage section 2 so as to be able to engage with and disengage from the carriage 20. It is being In the illustrated example, this "manual lever lever 23"
is a combination of a first lever 26 and a second lever 27, and the first lever 26 has a proximal end 26a.
is pivotally supported by the vehicle body 1, that is, by the rear lower portion 28 corresponding to the open side surface of the storage portion 2, and the tip portion 26b is rotatable. X indicates its pivot point. Furthermore, as shown in FIG. 6, this first lever 26 is provided with a locking groove 29 on the inside so that it can freely engage and disengage with a locking pin 30 protruding from the side surface of the truck 20. It doubles as a "front and rear stopper" to prevent movement in the front and rear directions. The lock groove 29 is recessed inside the first lever 26 to correspond to a circular arc centered on the pivot point X.

The base end 27a of the second lever 27 is connected to the first lever 2.
6, the tip 27b is rotatable, and the vehicle body 1 [specifically, the opening-shaped side surface of the storage section 2] It can be selectively engaged with and disengaged from the lock hole 31 (see Fig. 7) provided in the corresponding rear center part] or the trolley 20 (specifically, the aforementioned U-shaped pin receiving part 22). , "lateral stopper" that prevents the cart 20 [battery 3] from moving laterally.
It is designed for dual use. The engagement pin 24 is constantly biased in the direction of arrow A in FIG. hole 3
1 (see Fig. 7).

Next, the effect will be explained.

When moving the battery 3 along with the truck 20 forward from the storage section 2 to take it out, first remove the engagement pin 24 from the lock hole 31 of the vehicle body 1 and move it as shown by the arrow B in FIG.
Rotate the second lever 27 about the pivot point Y as shown in FIG. 1. Rotate the entire lever 26. At this time,
The lock groove 29 of the first lever 26 disengages from the lock pin 30 protruding from the side surface of the truck 20, and the truck 20 becomes movable forward. Arrow C
If the first lever 26 is rotated as shown in FIG. Move as shown D to pin receiver 2.
It becomes easy to enter into 2. After rotating the first lever 26 to the state shown in FIG.
4 into the pin receiving part 22, that is, positioning it by inserting it below the upper opening of the U-shaped pin receiving part 22. Then, if the first lever 26 is further rotated again in the direction of arrow E in FIG. 10, the first lever 26 and the second lever 27 will rotate around the pivot point and the first lever 26
As a result, the "manual lever lever 23" formed by the second lever 27
is moved forward as indicated by arrow F in FIG.

When storing a new replaced battery in the storage section 2, the cart 20 may be moved rearward via the manual lever 23 by performing the operation opposite to the above. In the states shown in FIGS. 5 and 8, if the lock groove 29 of the first lever 26 is engaged with the lock pin 30, the truck 20 (battery 3) is prevented from moving forward or backward. That is, the first lever 26 is used also as a stopper for moving forward and backward. Similarly, in the state shown in FIGS. 5 and 8, the engagement pin 24 of the tip 27b of the second lever 27 is engaged with the lock hole 31 of the vehicle body 1, and the second lever 27 is attached to the side of the truck 20 and the battery 3. In this case, the entire second lever 27 is obliquely obstructed, so that the cart 20 (battery 3) is prevented from moving laterally. That is, the second lever 27 is used also as a lateral movement stopper. If you want to pull out the battery 3 to the side for charging or other purposes, turn the second lever 27 largely as shown by arrow B in FIG. In this state, the battery 3 may be pulled out from above the carriage 20 which is fixed in position laterally via the roller 5 at the bottom of the battery 3.

Since the reach-type forklift according to the present invention has the content as described above, it is easy to battery the entire truck by just manually operating the manual lever lever.
It can be moved back and forth reliably and is easy to replace, and when the manual lever is engaged with the trolley, it can be used as a stopper for both forward and backward movement and lateral movement, ensuring that batteries are kept safe and secure in the storage area. This eliminates all the various problems caused by using a mast or reach cylinder as in the past. Another advantage is that even if the battery is nearly empty and there is no power to move the mast, the battery can be inspected while mounted on the vehicle with the battery pulled forward from the storage section. Furthermore, since the manual lever lever is formed of a first lever and a second lever, the first lever has the function of a longitudinal movement stopper, and the second lever has the function of a lateral movement stopper.
This has the effect that the effect of the moving stopper can be made even more reliable, and the "lever" function can be more easily exerted since the moving stoppers can be assigned to each part.
