Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport vehicle in which a support plate member is provided on a lower side of a rectangular frame member having a gripping portion on an upper portion, and wheels are rotatably provided on both ends of the lower side.

[0002]

2. Description of the Related Art For example, in a factory for processing small mechanical parts, a plurality of processed parts may be housed in buckets (returnable boxes) and transported between processes.

When such a bucket is transported manually by a worker, a hand truck (hand truck) as shown in FIG. 7 is often used. Further, a transport vehicle as shown in FIG. 8 may be used.

[0004]

However, the work of manually loading and unloading buckets from the wheelbarrow as described above requires bending the body while holding a heavy object.
In particular, when the buckets are heavy and must be stacked and mounted in multiple stages, there is a problem that it takes time and a great burden is imposed on an operator, which causes diseases such as back pain.

[0005] In addition, if a carrier is used, the bucket can be supported on the support plate without lifting the bucket. However, when the support plate is inserted under the bucket, the bucket must be tilted. The work was difficult.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a transport vehicle which is easy to mount without lifting heavy transported objects and has good workability.

[0007]

According to another aspect of the present invention, there is provided a carrier having a support member provided on a lower side of a rectangular frame member having a gripper at an upper portion, and a support plate provided on both sides of the lower side. In a transport vehicle having wheels rotatably provided, the support plate member is pivotally attached to the frame member so as to be swingable only on a side where an angle between the frame member and the frame member is reduced from a right angle to a narrow angle. It is characterized by being.

A fixed plate member is fixed below the support plate member of the frame member at a right angle to the frame member, and the support plate member has a tip protruding from the tip of the fixed plate member. And an angle formed with the frame member by the fixing plate member so that the swing from a right angle to a wide angle side is regulated and supported by the fixing plate member. .

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of a configuration example of a transport vehicle according to the present invention, and FIG. 2 is a longitudinal sectional view of a lower portion thereof.

The illustrated transport vehicle 1 is provided with a support base 20 as a support plate member and wheels 30 at the lower end of a rectangular frame 10.

The frame 10 is formed by connecting steel pipe vertical frame members 11 located on both left and right sides to steel plate connecting members 12, 13, and 14.
The upper end of the vertical frame member 11 is bent rearward at a predetermined angle via a bent portion 11B to form a grip portion 11A.

A fixing plate 15 protruding forward is provided at the lower edge of the lowermost connecting member 14. In this configuration,
The connecting member 14 and the fixed plate 15 are formed integrally by bending a flat plate at a right angle.

The support base 20 is formed of a steel plate into a rectangular shape in a plane shape, and is connected to the connecting member 14 via a hinge 21 at a rear edge thereof.
, The tip of which protrudes forward by a predetermined amount from the tip of the fixing plate 15. Thereby, in the free state, as shown by a solid line in FIG. Is regulated, and as shown by the imaginary line in the figure, the frame 1
On the side that is at a narrow angle with respect to 0, it can swing.

The wheel 30 is connected to the vertical frame member 11 of the frame 10.
Brackets 11C projecting rearward from the lower end of the
The frame 10 is vertical as shown in FIG. 2 and the support table 20 is horizontal along the floor 2, and its outer peripheral surface is in contact with the floor 2. Is set to

Thus, in the transport vehicle constructed as described above, it is possible to transport the transported object by supporting it on the upper surface of the support plate by operating as follows.

That is, as shown in FIG. 3, after the transport vehicle 1 is positioned at predetermined intervals so as to face buckets 3 stacked in a plurality of stages as a transported object, the upper portion of the frame 10 (gripping portion 1)
1A) is moved toward the bucket 3 (to the front).
At this time, the entirety of the transport vehicle 1 is such that the tip of the fixed plate 15 is
, And swings with the fulcrum as a fulcrum, and the support table 20 swings to the side at a narrow angle with respect to the frame 10 to allow it. Thereby, the angle of the support base 20 with respect to the floor surface 2 is: θ
2 is smaller than the swing angle of the frame 10: θ1.
Next, after the vertical frame member 11 of the frame 10 and the bent portion 11B of the grip portion 11A contact the bucket 3, the bucket 3 is further swung by a predetermined angle to tilt the bucket 3 as shown in FIG. A gap 3 is formed between the lower surface of the front side (the side of the truck 1) and the floor surface 2.
A, and kicking the rear part of the transport vehicle 1, as shown in FIG.
Slide in. At this time, the carrier 1 has its support 2
Since only 0 and the tip of the fixed plate 15 contact the floor surface 2 and the weight is supported only by the fixed plate 15, it can be easily moved by impact (by kicking in from the rear side).

Then, the carrier 1 and the bucket 3 are integrally swung toward the near side (right side in the figure) to support the bucket 3 with the support base 20 and the frame 10 as shown in FIG.
Means moving the vehicle in a state of contact only through the wheels 30.

According to the above configuration, since the support base 20 can swing to the side at a narrow angle with respect to the frame 10, the frame 10 shown in FIG.
Even when the bucket 3 is pressed and inclined by 1B, the bucket 3 is kept at a small angle with respect to the floor surface 2 (that is, a posture close to being parallel), so that the bucket 3 can be stably supported. Even when the protrusion amount of the protrusion 20 is set large, the interposition between the lower surface of the bucket 3 and the floor surface 2 can be easily performed. That is, when the support base 20 is fixed so as not to be able to swing, the frame 10 is swung and the bucket 3 is pressed by the bent portion 11B so that the bucket 3 is inclined. Is raised at an angle equal to the swing angle of the frame 10 and it becomes difficult to interpose between the lower surface of the bucket 3 and the floor surface 2. However, this is not the case with the configuration of the present application. .

In the above configuration example, the swing of the support base 20 from the right angle to the wide angle with respect to the frame 10 is fixed to the fixed plate 1.
5, the support plate 20
The swing restriction structure to the wide angle side is not limited to this.
The configuration can be appropriately changed as long as the configuration can withstand the weight of the load (the bucket 3). For example, the hinge 21 attached to the connecting member 14 may be provided with an angle restricting structure.
Can always be positioned parallel to the floor surface 2 irrespective of the swing angle of the frame 10, and the interposition between the lower surface of the bucket 3 and the floor surface 2 is further facilitated.

[0020]

As described above, according to the carrier according to the present invention, the support plate member can swing on the lower side of the frame member only on the side where the angle formed by the frame member from a right angle to a narrow angle. The support plate member is configured to be pivotally mounted on the support plate member, so that the amount of protrusion of the support plate member is set large so that the conveyed object can be stably supported, and even if the frame member is swung forward, the support plate member remains on the floor. The state along the surface can be maintained, and by swinging the frame member, the bucket is inclined with the frame member to generate a gap between the lower surface on the near side and the floor surface, and the support plate member is placed in the gap. By sliding in, it becomes possible to mount the load on the support member. In other words, it is possible to easily load a load without lifting a heavy load.

A fixing plate member is fixed below the support plate member of the frame member at a right angle to the frame member. The frame member swings forward by being configured to be supported in a state where the angle between the frame member and the frame member is increased from a right angle to a wide angle by the fixed plate member. Even if this is done, the support plate member keeps a small angle with respect to the floor surface and the fixed plate member can hold the weight of the goods, so the protrusion amount of the support plate member is increased so that the goods can be stably supported. In addition to the setting, the tip of the fixed plate member comes into contact with the floor surface and the weight of the fixed plate member is supported only by the fixed plate member in a state where the transport vehicle is swung and the load is tilted. Kick in from At) are those that can be easily moved.
