Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a lightweight and compact forklift capable of expanding and contracting a wheel base.

[0002]

2. Description of the Related Art A forklift performs a cargo handling operation by using a fork disposed in front of a vehicle. Therefore, when the load is lifted by the fork, a forward moment is generated. To maintain the stability of the vehicle against this overturning moment, a counterweight is installed at the rear of the forklift to keep the balance. In order to secure a sufficient stability moment of the vehicle body, it is necessary to set the position of the center of gravity of the vehicle as rearward as possible and to increase the weight of the vehicle body by weight. For this reason, forklifts are machines that have a longer overall vehicle length and heavier vehicle weight.

[0003] On the other hand, from the standpoint of using a forklift, a sufficient stable moment is not always required depending on the type of baggage handled and the working condition. for that reason,
There is a demand for a lightweight and compact forklift. For example, there are the following requirements.

[0004] Both heavy and light luggage are handled,
Lighter and more compact forklifts are better because there are more light luggage. Also, while working in both narrow and wide areas, when working in narrow areas, only light luggage is handled, so a lighter and more compact forklift is better.
We want to transport the forklift by truck and transport it to the workplace, so it is better to have a lightweight and compact forklift when not loading cargo.

[0005] In response to such demands, a number of techniques relating to forklifts have been proposed in which the position of the center of gravity of the vehicle body can be moved in the front-rear direction with respect to the overturning fulcrum. These are roughly divided into those that move the counterweight back and forth with respect to the vehicle body (JP-A-59-42764, etc.), those that make the wheel base telescopic (JP-A-59-22894, etc.), those that use the front wheel or It is divided into a type in which an outrigger with wheels is moved forward with respect to a fork (Japanese Patent Application Laid-Open No. S51-35952).

[0006]

However, all the prior arts have a drawback that the amount of movement of the center of gravity of the vehicle body is not sufficient, and thus the effect of reducing the weight and size is small. Also,
In the case where the front wheel or the outrigger with wheels is moved forward with respect to the fork, there is a disadvantage that the front wheel is located forward of the base of the fork.

The present invention has been made in view of the above-mentioned conventional problems, and aims to solve the above-mentioned disadvantages and to provide a lightweight and compact forklift capable of greatly expanding and contracting a wheel base in a counterbalance type forklift. is there.

[0008]

A first aspect of the present invention is a counterbalance type forklift capable of expanding and contracting a wheel base, the forklift comprising a front frame having a pair of left and right outer rails, and a forklift with respect to the outer rail. A rear frame having a pair of left and right inner rails slidably disposed, the front frame supporting a front wheel and a cargo handling device, the rear frame supporting a rear wheel and a counterweight, and The front wheel is outside the outer rail,
The forklift is characterized in that the rear wheels are disposed inside the inner rails, respectively, and are configured so that the outer rails and the inner rails can slide without interfering with the front wheels and the rear wheels. is there.

The most remarkable point of the present invention is that the front frame having the outer rails and the rear frame having the inner rails are combined, and the front wheels and the rear wheels are specified as described above. That is, it was arranged in a position.

Next, the operation and effect of the present invention will be described.
As described above, the forklift of the present invention is configured by combining the front frame and the rear frame.
The outer rail of the front frame and the inner rail of the rear frame are provided so as to be slidable with each other. In addition, the front frame has front wheels,
The rear wheel is arranged on the rear frame. Therefore, the wheel base can be easily changed by sliding the front frame and the rear frame.

Further, in the present invention, the front wheel is disposed outside the outer rail, and the rear wheel is disposed inside the inner rail. Therefore, when the outer rail and the inner rail are slid, interference between the outer rail and the inner rail with the front wheel and the rear wheel can be reliably eliminated. Therefore, the sliding distance between the outer rail and the inner rail can be made very large, and the change interval of the wheel base can be made large.

The front frame is provided with a cargo handling device and front wheels, and the rear frame is provided with a counterweight. Therefore, the sliding moment between the front frame and the rear frame can change the stability moment of the vehicle body.

That is, since the forklift of the present invention is of a counterbalance type, the loading operation is performed by a loading device located forward of the front wheels. Therefore, the fulcrum is the front wheel. Here, when the front frame and the rear frame are slid so as to contract each other, the center of gravity of the vehicle approaches the front wheels, and the stable moment decreases. on the other hand,
When the front frame and the rear frame are slid so as to extend from each other, the center of gravity of the vehicle moves away from the front wheels, and the stability moment increases.

By increasing the amount of change in the stable moment in this way, it is possible to achieve a sufficiently lightweight and compact design. That is, the weight of the counterweight can be reduced as much as the wheelbase can be made larger than before. Further, the overall length of the forklift can be shortened by the amount by which the wheelbase can be made smaller than before.

Next, it is preferable that the front frame and the rear frame are connected to an actuator for sliding the front frame and the rear frame. The sliding movement between the front frame and the rear frame can be performed by using a traveling function of a forklift, for example. However, by providing the dedicated actuator as described above, the slide movement can be performed very easily.

Further, when the outer rail and the inner rail are contracted to the minimum as in the third aspect of the invention, the shaft center of the rear wheel is accommodated inside the outer rail. Is preferred. In this case,
The sliding amount of the outer rail and the inner rail, that is, the expanding and contracting amount of the wheel base can be further increased.

According to the present invention, the wheel base when the outer rail and the inner rail are maximized is one of the wheel bases when the outer rail and the inner rail are minimized. It is preferably at least 0.5 times. That is, in the above-described frame structure, as described above, it is not necessary to consider the interference between the front wheel and the rear wheel, so that the amount of expansion and contraction of the wheel base can be easily adjusted by the length of the outer rail and the inner rail. Therefore, the elongation of the wheel base can be easily increased to 1.5 times or more, thereby further reducing the weight and size of the forklift.

According to a fifth aspect of the present invention, the outer rail has a U-shape in which an upper plate, a horizontal plate, and a lower plate are arranged in a U-shape and an opening is provided inside. The inner rail comprises two rollers provided between the upper plate and the lower plate of the U-shaped rail.
It is preferable to have at least one. In this case, a structure in which the outer rail and the inner rail are slidable can be easily realized.

According to a sixth aspect of the present invention, the outer rail has a U-shape in which an upper plate, a horizontal plate, and a lower plate are arranged in a U-shape and an opening is provided inside. The inner rail may have a pad that is slidably disposed inside the U-shaped rail. In this case as well, a slidable structure of the outer rail and the inner rail can be easily realized in the same manner as described above.

According to a seventh aspect of the present invention, a hydraulic motor for running the vehicle is disposed inside the front wheel or the rear wheel, and is connected to the hydraulic motor via a hydraulic circuit. It is preferable that the engine for driving the oil pump is arranged such that the longitudinal direction of the engine is oriented in the lateral direction of the vehicle. In this case, as described above, since the hydraulic drive system is employed, there is no need to arrange a power transmission device required for driving the engine. Therefore, the total length of the vehicle can be shortened by the amount of eliminating the power transmission device. In addition, the overall length of the forklift can be further reduced by disposing the engine for driving the oil pump such that the longitudinal direction thereof is oriented in the lateral direction of the vehicle, that is, by placing the engine horizontally.

According to the present invention, a hydraulic oil tank or a fuel tank is disposed in front of the engine, and at least a part of the hydraulic oil tank or the fuel tank is provided on the floor of the cab. It is preferable to be arranged so as to protrude upward from the center of the surface. In this case, the height of the hydraulic oil tank or the fuel tank can be increased by seating the driver over the hydraulic oil tank or the fuel tank. As a result, the hydraulic oil tank or the fuel tank can be shortened in the vehicle front-rear direction, so that the total length of the forklift can be shortened accordingly.

According to a ninth aspect of the present invention, the hydraulic motor is disposed on each of the pair of left and right front wheels, and at least a part of the mast of the cargo handling device is mounted on the vehicle relative to the front end of the hydraulic motor. It is preferable to be arranged so as to be located on the rear side. In this case, since there is no need to dispose a power motor, it is possible to secure a space between the left and right hydraulic motors where a part of the mast can be disposed. As a result, the mast can be brought closer to the front wheel, which is the overturning fulcrum, so that the counterweight for countering the overturning moment can be reduced in weight and size.

According to a tenth aspect of the present invention, the hydraulic motor is disposed on the rear wheel, and at least a part of the mast of the cargo handling device is located between the wheel center lines of the pair of left and right front wheels. It is preferable to be arranged so as to be located on the rear side of the vehicle. In this case, since there is no possibility that the mast interferes with the support member of the hydraulic motor, the mast can be brought closer to the front wheels. for that reason,
The overall length of the forklift can be made shorter than when a hydraulic motor is arranged on the front wheels.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment A forklift according to an embodiment of the present invention will be described with reference to FIGS. Forklift 1 of this example
Is a counterbalance type forklift capable of expanding and contracting a wheel base W as shown in FIG.
The forklift 1 has a front frame 2 having a pair of left and right outer rails 20 as shown in FIGS.
And a rear frame 3 having a pair of left and right inner rails 30 slidably disposed with respect to the outer rail 20.

The front frame 2 supports the front wheels 11 and the cargo handling device 10, and the rear frame 3 supports the rear wheels 12 and the counterweight 13.
Further, the front wheel 11 is disposed outside the outer rail 20 and the rear wheel 12 is disposed inside the inner rail 30, so that the outer rail 20 does not interfere with the front wheel 11 and the rear wheel 12. And the inner rail 30 can be slid.

Hereinafter, this will be described in detail. First, as shown in FIG. 3, the front frame 2 is provided with a pair of left and right outer rails 20 connected by two connecting members 21 and 22. Also, at the tip of the outer rail 20,
Bracket 2 for connecting to hydraulic cylinder 4 described later
3 is provided. On the other hand, the rear frame 3 is provided with a pair of left and right inner rails 30 connected by two connecting members 31, 32, as shown in FIG.

As shown in FIG. 4, each of the outer rails 20 has an upper plate portion 201, a horizontal plate portion 202, and a lower plate portion 203 arranged in a U-shape and an opening provided on the inner side. It is provided from the shape rail. On the other hand, the inner rail 30 has two right and left rollers 301 provided between the upper plate portion 201 and the lower plate portion 203 of the U-shaped rail.

As shown in FIG. 1, the cargo handling device 10 is disposed on the front frame 2 so as to be sandwiched between the distal ends of the outer rails 20, and the front wheel 11 is located outside the distal end of the outer rails 20. It is arranged in. Also,
The front wheels 12 of this example are of a hydraulic drive type, and a hydraulic motor 14 as each drive device is a so-called wheel-in type traveling motor, and is incorporated inside each front wheel 12.

At the rear end of the rear frame 3, a member 33 for supporting the counterweight 13 and the rear wheel 12 is provided. The rear wheel 12 of this example is a single wheel type and is disposed at the center in the width direction of the vehicle body. In addition to the rear wheel 12 and the counterweight 13, the rear frame 3 is provided with a driving operation unit including a hydraulic power source, a driver's seat 16, a steering wheel 171 and the like.

As shown in FIG. 1, the front frame 2 and the rear frame 3 are connected to a hydraulic cylinder 4 as an actuator for sliding them. The hydraulic cylinder 4 is disposed on the left and right by connecting one end to a bracket 23 provided on the front frame 2 and the other end to a connecting member 32 of the rear frame 3.

Further, as shown in FIGS. 1 and 2, the cargo handling device 10 in this embodiment is a normal type of lifting and lowering a fork 102 along a mast 101. Also,
As shown in FIG. 2A, the fork 102 is provided in a reversible manner so that its tip is directed rearward.

Next, the operation and effect of this embodiment will be described. As described above, the forklift 1 of this embodiment is provided so as to be slidable by combining the front frame 2 and the rear frame 3. Further, the front wheel 11 is disposed outside the outer rail 20 and the rear wheel 12 is disposed inside the inner rail 30. Therefore, when the outer rail 20 and the inner rail 30 are slid,
1 and the rear wheel 12 can be reliably eliminated.
Therefore, the length of the outer rail 20 can be set to be long, and the sliding distance can be greatly increased. Specifically, the wheel base W when the outer rail 20 and the inner rail 30 are maximized can be made about twice as large as the wheel base W when the outer rail 20 and the inner rail 30 are reduced to the minimum. Was.

The front frame 2 is provided with a cargo handling device 10 and a front wheel 11, and the rear frame 3 is provided with a counterweight 13. Therefore, the sliding moment between the front frame 2 and the rear frame 3 can greatly change the stability moment of the vehicle body.

For example, as shown in FIGS. 1 (a) and 2 (a), when the front frame 2 and the rear frame 3 are slid to contract each other, the counterweight 13 is attached to the front wheel 11 which is a fall fulcrum. By approaching, the center of gravity of the vehicle approaches the front wheel 11, and the stability moment decreases. On the other hand, as shown in FIGS. 1B and 2B, when the front frame 2 and the rear frame 3 are slid so as to extend from each other, the center of gravity of the vehicle moves away from the front wheels 11, and the stable moment increases.

By increasing the amount of change in the stability moment in this way, it is possible to achieve a sufficiently lightweight and compact design. That is, in this example, since the wheelbase W can be made larger and the overall length of the vehicle can be made longer than before,
The weight of the counterweight 13 etc. can be reduced,
The weight of the entire vehicle can be reduced to about 2/3 of the conventional weight. Further, since the wheel base W can be shortened and shortened as compared with the conventional case, the total length of the vehicle can be reduced to about 2/3 of the conventional case.

Further, in the present embodiment, as shown in FIG. 2A, the fork 102 can be turned over, so that the total length when the cargo is not unloaded can be further reduced. Therefore, the storage space of the forklift 1 is reduced, or
Transportation of the forklift 1 by truck can be facilitated.

In this embodiment, the outer rail 20
The inner rail 30 and the inner rail 30 are constructed by combining the U-shaped rail and the roller 301.
Instead of 1, a pad slidable on the U-shaped rail can be used. Further, it is of course possible to provide a roller on the outer rail 20 and make the inner rail 30 a U-shaped rail having an opening on the outside.

Embodiment 2 In this embodiment, as shown in FIG. 5, the front frame 2 and the rear frame 3 are fixed by pins 6, the hydraulic cylinder 4 is removed, and the expansion and contraction of the wheel base is controlled by a forklift. This is an example of self-propelled operation.

That is, as shown in FIG. 5, through-holes 61, 62, 63 into which the pins 6 can be inserted are respectively formed in the connecting members 21, 22 in front of and behind the front frame 2 and the connecting member 31 in front of the rear frame 3. Is provided. And FIG.
As shown in FIG. 6, when the front frame 2 and the rear frame 3 are contracted, the through-holes 61 and 63 are overlapped and the pins 6 are inserted to maintain the contracted state of the wheel base (FIG. 6A )). When the front frame 2 and the rear frame 3 are extended, the through-holes 62 and 63 are overlapped and the pins 6 are inserted to maintain the extended state of the wheel base (FIG. 6B).

The expansion and contraction of the wheel base is carried out by the forklift 1 using the driving force of the front wheels 11 by itself. Specifically, the rear wheel 12 is cut by 90 degrees, or the rear wheel 12 is fixed to the rear wheel 12 with a clasp. Next, the front frame 2 is moved forward and backward with respect to the rear frame 3 by removing the pins 6 and driving the front wheels 11. Next, the positional relationship between the front frame 2 and the rear frame 3 is fixed by inserting the pins into the through holes at desired positions.

As described above, in this embodiment, the hydraulic cylinder 4 as the moving device as in the first embodiment can be dispensed with. Therefore, the structure of the forklift 1 can be simplified and the cost can be reduced. Others
The same function and effect as those of the first embodiment can be obtained.

Embodiment 3 In this embodiment, the driving method of the front wheel 11 in Embodiment 1 is described as follows.
This is a modified example. That is, as shown in FIGS. 7 and 8, an axle unit having a differential was used as a drive device of the front wheel 11, and the axle was housed in the axle 7 between the left and right front wheels 11.

In this case, the number of traveling motors for driving the front wheels 11 can be reduced to one, and the cost can be reduced. On the other hand, the expansion and contraction stroke of the outer rail 20 and the inner rail 30 is shortened by the presence of the axle 7, so that the expansion and contraction amount of the wheel base is smaller than in the case of the first embodiment. Otherwise, the same operation and effect as those of the first embodiment can be obtained.

Embodiment 4 This embodiment is an example in which the arrangement of devices and masts inside the vehicle body is changed. That is, as shown in FIG. 9, an engine 52 for driving an oil pump 51 connected to the hydraulic motor 14 via a hydraulic circuit (not shown) having various valves.
Are arranged such that the longitudinal direction L of the engine is oriented in the lateral direction of the vehicle.

A hydraulic oil tank 53 is arranged in front of the engine 52. The hydraulic oil tank 53 is arranged with its upper part 531 projecting upward from the center of the floor 55 of the cab. . Note that a fuel tank 54 is arranged beside the engine 52.

The mast 101 is arranged such that the rear portion 103 is located on the vehicle rear side with respect to the front end of the hydraulic motor 14. Note that the hydraulic motors 14 for running the vehicle are disposed inside the pair of left and right front wheels 11 as in the first embodiment.

In this embodiment, as described above, since the hydraulic drive system is employed, a clutch, a transmission, an axle (see FIG. 10) and the like as a power transmission device are provided between the engine 52 and the front wheels 11. No need to place. for that reason,
The overall length of the forklift 1 according to the present embodiment can be shortened by the amount of no power transmission device. The engine 52
Can be further shortened by placing the forklift 1 horizontally.

Further, the driver is provided with the upper part 5 of the hydraulic oil tank 53.
By seating the vehicle over the strut 31, the height of the hydraulic oil tank 53 can be increased. Therefore, the hydraulic oil tank 53 can be shortened in the vehicle front-rear direction, so that the total length of the forklift 1 can be further shortened. Note that the same effect can be obtained even if the hydraulic oil tank 53 and the fuel tank 54 are interchanged.

The transmission, between the left and right front wheels 11,
Since there is no need to arrange an axle or the like, a space where the rear part of the mast 101 can be arranged can be secured between the left and right hydraulic motors 14. Therefore, the mast 101 can be brought closer to the front wheel 11, which is a fulcrum,
Counterweight 1 for countering overturning moment
3 can be reduced in weight and size. Therefore, the total length of the forklift 1 can be further reduced. Otherwise, the same operation and effect as those of the first embodiment can be obtained.

The floor 55 of the cab can be located below the upper surface of the hydraulic oil tank 53. As a result, the ground clearance on the floor can be significantly reduced,
The driver can easily get on and off.

Here, for comparison, an example is shown in which a power transmission device is provided between the engine and the front wheels instead of providing a hydraulic motor. That is, in this comparative example, FIG.
As shown in the figure, the engine 5
2, the clutch 56, the transmission 57, and the axle 7 are arranged substantially linearly toward the front of the vehicle. Then, the motive power of the engine 52 is sequentially transmitted to the clutch 56, the transmission 57, and the axle 7 to drive the left and right front wheels 11.

In this comparative example, the mast 101 can be arranged only far ahead of the axle of the front wheel 11 due to the presence of the transmission 57 and the axle 7. Therefore, the mast 101 in the present comparative example is located far ahead of the vehicle than the forklift 1 of the fourth embodiment. For this reason, the counterbalance 13 must be made larger than in the fourth embodiment.

Further, the engine 52, the clutch 56, the transmission 57, and the axle 7 are arranged along the longitudinal direction of the vehicle. Therefore, the forklift 9 of the present comparative example has a longer overall length than the forklift 1 of the fourth embodiment. Also,
In the forklift 9 of the present comparative example, the clutch 56, the transmission 57, the axle 7 and the like are all disposed below the floor surface 55 of the cab, so that the floor height above the forklift 1 of the fourth embodiment is higher. . By comparison with this comparative example,
It can be seen that the forklift 1 of the fourth embodiment is very compact and the overall length is being reduced.
