Abstract

PROBLEM TO BE SOLVED: To provide a practice instrument for cargo handling operation of a forklift which can be practiced safely and easily without using an expensive device. SOLUTION: Since at least an outer peripheral portion 22 of a bottom surface 21 of a casing 20 is formed to be convexly curved, the exercise instrument 10 easily swings when an external force is applied. Further, since the weight 30 is provided on the inner surface of the bottom surface 21 of the housing 20, when the external force does not act, the exercise instrument 10 returns to the upright state by the action of the weight 30. For this reason, it can be easily detected that the fork is not properly inserted into the fork insertion hole 26, and practice can be easily performed any number of times. [Selection] Figure 1

Description

  The present invention relates to a practice instrument for carrying out a cargo handling operation of a forklift.

  2. Description of the Related Art Generally, a forklift is a cargo handling vehicle having a fork (claw) that can be lifted and lowered using electric power and hydraulic pressure on the front surface of a vehicle body, and is used for cargo handling that lifts and carries a heavy load.

  For example, an example of a forklift is shown in FIG. The forklift 100 has a machine base 101, and a mast 102 provided in the vertical direction at a front portion of the machine base 101 and a pair of forks 103, 103 provided so as to be movable up and down along the mast 102. Is provided. Depending on the type of forklift 100, there is a type in which the mast 102 can move back and forth along the machine base 101 (reach type). Further, at the rear of the machine base 101, a driver's seat 104 on which a driver sits or stands and rides, a handle 105 and a plurality of operating rods 106 that are operated by a driver on the driver's seat 104 are provided. ing.

  A traveling wheel 107 is provided on the lower surface of the machine base 101 at the front and rear, and a power unit for traveling (not shown) and a power part for lifting and lowering the fork (not shown) are provided in the machine base 101. Is provided. The power units include those using electric power using a motor and a battery, and those using an engine.

  Therefore, when performing cargo handling using the forklift 100, the operator operates the handle 105 in the driver's seat to position the forklift 100 at a predetermined position in front of the load. Then, the operator operates the operating rod 106 to raise and lower the fork 103 and move it forward, and insert the fork 103 into a lower portion of the load or a predetermined position on the pallet on which the load is placed. Thereafter, the operator raises the fork 103 to lift the load, and travels the forklift 100 to carry the load.

  In cargo handling work using the forklift 100, since heavy objects are usually handled, the operator must insert the fork 103 accurately and sufficiently into a lower part of the load or a predetermined position on the pallet from the viewpoint of work safety. . In other words, when the fork 103 is inserted with a deviation from a predetermined position or not fully inserted, the load may fall or tilt, and a safe operation may not be performed.

  For this reason, it is desired that the operator is sufficiently skilled in the operation of the forklift 100 before performing actual work. Particularly, forklifts generally use rear wheel steering, so the steering direction of the steering wheel and the behavior of the vehicle (inner wheel difference, outer wheel difference) are opposite to those of ordinary automobiles. Further, since the lifting operation of the fork 103 is unique to the forklift 100, it is necessary to get used to the operation of the operation rod 106 in order to perform a safe work.

Conventionally, a simulator is sometimes used to practice driving of an automobile or the like (see Patent Document 1).
In such a driving practice machine, a handle and a pedal are provided in front of the practitioner sitting on the seat, and a video display is provided in front of the practitioner's eyes. Then, the practitioner practices driving the vehicle by operating the steering wheel, the pedal, and the like according to the scenery displayed on the video display to drive the vehicle.
It is also possible to practice cargo handling work using a forklift using such a training machine.

JP 2012-121535 A

However, the driving practice machine using the simulator as described in Patent Document 1 described above has a problem that it is expensive because it generally uses an expensive video device or the like.
On the other hand, it is conceivable to practice using actual forklifts by transporting the actual luggage, but in this case, the heavy luggage may fall and cause danger to the surroundings, or the luggage may be damaged. There is a problem that it cannot be practiced easily.

  The present invention has been made to solve the conventional problems, and an object of the present invention is to provide a practice instrument for cargo handling operation of a forklift that can be practiced safely and easily without using an expensive device. To do.

(A) is a front view of a practice instrument for cargo handling operation of a forklift according to an embodiment of the present invention as seen from the forklift side, (B) is a side view as seen from the direction of arrow B in (A), (C) is the bottom view seen from the arrow C direction in (A). It is explanatory drawing which shows the case where a fork can be appropriately inserted into a fork insertion hole. It is explanatory drawing which shows the case where a fork cannot be inserted appropriately in a fork insertion hole. It is a perspective view which shows an example of a conventional forklift.

  Hereinafter, a training implement for carrying out a cargo handling operation of a forklift according to an embodiment of the present invention will be described with reference to the drawings. In the following description, the forklift will be described using the forklift 100 described above with reference to FIG. 5, and redundant description will be omitted.

  As shown in FIGS. 1 and 2, a practice instrument 10 (hereinafter referred to as “practice instrument 10”) for carrying out a cargo handling operation of a forklift 100 according to an embodiment of the present invention is used in practice, that is, in a standing state. It has a cylindrical casing 20 extending in the vertical direction.

As shown in FIG. 2C, the housing 20 has, for example, a substantially rectangular cross section, and the bottom surface 21 is formed of a hard member that does not allow air to pass. It is possible to stand and stand (see FIG. 3).
As shown in FIGS. 2A to 2C, the bottom surface 21 has an outer peripheral portion 22 and a central portion 23 surrounded by the outer peripheral portion 22. The central portion 23 is formed as a substantially flat surface (curvature≈zero) or a curved surface having a small curvature and a downward convex shape. Further, at least the outer peripheral portion 22 is formed with a curved surface that is convexly convex downward, and is curved upward with a curvature that is greater than the curvature of the central portion 23 toward the outside.

  A weight 30 is attached to the inner surface 24 of the bottom surface 21, that is, inside the housing 20. The material, shape, weight, and the like of the weight 30 are not particularly limited, but the shape and weight (that is, thickness) in plan view are centered on the center line CL1 of the inner surface 24 of the bottom surface 21 (center line CL2). It is desirable to be symmetrical in the front-rear and left-right directions, such as a disk shape, a truncated cone, and a part of a sphere. Here, the case where the disk-shaped weight 30 is used is illustrated.

  Accordingly, when the bottom surface 21 is placed on the ground G or the like in a state where no external force is applied, the substantially flat central portion 23 of the bottom surface 21 is in contact with the ground G as shown in FIG. Stand upright. When an external force acts on the housing 20 in the front / rear and left / right directions, the curved outer peripheral portion 22 of the bottom surface 21 comes into contact with the ground G as shown in FIG. When the external force is removed, the casing 20 returns to a substantially upright state by the action of the weight 30.

  As shown in FIGS. 1 and 2A, a pair of fork insertion holes 26 are provided on the front surface (side surface) 25 of the housing 20 corresponding to the distance between the forks 103 of the forklift 100. The fork insertion holes 26 are provided in multiple stages (here, for example, three stages) along the vertical direction of the housing 20. In the following description, when the fork insertion holes 26 are distinguished, the fork insertion holes 261 and the fork insertion holes 262 are indicated.

The cross-sectional dimension of the fork insertion hole 26 is set such that the height dimension and the width dimension are larger than the thickness dimension and the width dimension of the fork 103 so that the fork 103 can be inserted. The cross-sectional shape of the fork insertion hole 26 may be, for example, a rectangular shape or an elliptical shape into which the fork 103 can be inserted. Here, the case where the cross-sectional shape of the fork insertion hole 26 is rectangular is shown. Further, the length (depth) D2 of the fork insertion hole 26 may be longer than the length of the fork 103 or may penetrate to the rear surface 27 on the opposite side.
Thereby, the fork 103 can be completely inserted into the fork insertion hole 26.

It is desirable that the distance D1 between the center CL3 of the fork insertion hole 261 and the center CL4 of the fork insertion hole 262 is substantially equal to the center distance between both forks 103 in the forklift 100. Further, it is desirable that the center (center line CL5) between the fork insertion hole 261 and the fork insertion hole 262 be disposed at the approximate center (center line CL6) in the width direction of the housing 20.
As a result, the center of gravity of the housing 20 is positioned on a plane passing through the center (center line CL5) between the fork insertion hole 261 and the fork insertion hole 262, so that the fork 103 inserted into the fork insertion hole 26 is raised. Thus, when the training instrument 10 is lifted, the balance can be maintained.

The housing 20 is desirably formed in a balloon shape having the above-described shape by press-fitting air into the inside. The housing 20 can be formed using, for example, strong vinyl, and is provided with a pneumatic inlet 28 for press-fitting air into the housing 20.
Therefore, the casing 20 before the air is press-fitted can be crushed. Then, by connecting an electric air pump or the like to the pneumatic inlet 28 and press-fitting air into the housing 20, the housing 20 expands upward to become a cylindrical shape, and a fork insertion hole 26 is formed. .

Next, a practice operation of the forklift 100 performed using the practice instrument 10 of the present embodiment will be described.
First, as shown in FIG. 3, the forklift 100 is moved so that the center between the pair of forks 103, 103 and the center (center line CL5) between the fork insertion hole 261 and the fork insertion hole 262 substantially coincide with each other. Let At the same time, the forklift 100 is directly opposed to the front surface 25 of the practice instrument 10 so that the extending direction of the fork 103 is parallel to the direction of the fork insertion hole 26. Next, the fork 103 is moved up and down and positioned so that the tip of the fork 103 faces the entrance of the fork insertion hole 26. Then, the fork 103 is advanced toward the practice instrument 10 and inserted into the fork insertion hole 26.

At this time, if the front end of the fork 103 does not face the fork insertion hole 26, the front end of the fork 103 pushes the front surface 25 of the practice instrument 10 when the fork 103 is advanced, so as shown in FIG. The instrument 10 swings backward (see arrow A in FIG. 4).
As a result, it can be easily understood that the position of the fork 103 is displaced from the fork insertion hole 26, and the practitioner moves the fork 103 backward. When the fork 103 moves backward, the training instrument 10 returns to an upright state by the action of the weight 30 (see arrow B in FIG. 4).

Here, when the fork 103 is displaced in the left-right direction with respect to the fork insertion hole 26, the fork lift 100 is moved in the left-right direction by moving the fork lift 100 in the left-right direction, and again the fork with respect to the fork insertion hole 26 is restored. Attempt to insert 103.
When the fork 103 is displaced in the vertical direction with respect to the fork insertion hole 26, the fork 103 is moved up and down to adjust the height, and the insertion of the fork 103 is attempted again.

Even when the tip of the fork 103 faces the entrance of the fork insertion hole 26, if the extension direction of the fork 103 does not coincide with the direction of the fork insertion hole 26, the fork 103 is directed toward the practice instrument 10. Since the fork 103 pushes the inner wall of the fork insertion hole 26, the practice instrument 10 swings backward and obliquely.
Accordingly, it can be easily understood that the extending direction of the fork 103 does not coincide with the direction of the fork insertion hole 26, and the practitioner moves the fork 103 backward. When the fork 103 is retracted, the practice instrument 10 returns to the upright state, so that the forklift 100 is moved and turned so that the extending direction of the fork 103 is parallel to the direction of the fork insertion hole 26. Then, it tries to insert the fork 103 again.

When the fork 103 can be properly inserted into the fork insertion hole 26 of the practice instrument 10, the practitioner raises the fork 103. At this time, when the fork 103 is not sufficiently inserted into the fork insertion hole 26, the front part of the practice instrument 10 is lifted, and thus the practice instrument 10 swings backward.
As a result, it can be easily understood that the insertion is not sufficient, so the insertion of the fork 103 is attempted again.

When the fork 103 can be properly inserted into the fork insertion hole 26 and the practice instrument 10 can be lifted, the practitioner runs the forklift 100 to practice running.
When the practice is finished, the air inside the housing 20 is removed from the pneumatic inlet 28 and cleaned up.

Next, a specific example of the practice instrument 10 will be described.
As shown in FIGS. 2 (A) and 2 (B), the overall height H1 of the practice instrument 10 in a state where air is press-fitted into the housing 20 can be 3 m to 5 m. Moreover, full width B1 of the training instrument 10 can be 1 m-1.5 m. Furthermore, the thickness D2 of the training instrument 10 can be 1 m. Although the fork insertion hole 26 is provided in three stages on the front surface 25 of the training instrument 10, the range H2 in which the fork insertion hole 26 is provided can be 70 cm to 1 m. The fork insertion hole 26 can have a width B2 of 30 cm and a height H3 of 15 cm to 20 cm.
In addition, the said numerical value is an example and is not limited to this.

As described above, according to the practice instrument 10 for cargo handling operation of the forklift 100 of the present embodiment, at least the outer peripheral portion 22 of the bottom surface 21 of the housing 20 is formed to be convexly curved. When it works, it swings easily.
For this reason, when the pair of forks 103 of the forklift 100 cannot be properly inserted into the pair of fork insertion holes 26 provided in the front surface 25 of the housing 20, the exercise instrument 10 is pushed by the fork 103 and swings. Therefore, it can be easily detected that the insertion is not properly performed (see FIG. 4).

Further, since the weight 30 is provided on the inner surface 24 of the bottom surface 21 of the housing 20, when the external force does not act, the exercise instrument 10 returns to the upright state by the action of the weight 30.
For this reason, when the proper insertion of the fork 103 fails, the original state is restored simply by retracting the fork 103, so that the practice can be easily performed any number of times.

Further, according to the practice instrument 10 for cargo handling operation of the forklift 100 of the present embodiment, the housing 20 is formed of a balloon-like member that is formed into a cylindrical shape by pressurizing air into the interior from the pneumatic inlet 28. Because it is very light, you can practice safely and dare.
Furthermore, since it is very lightweight, it can be set and cleaned up easily. Moreover, since it becomes small when the air is extracted, it does not take a storage space when not in use.

  In addition, according to the practice instrument 10 for carrying out a cargo handling operation of the forklift 100 of the present embodiment, the fork insertion holes 26 are provided in pairs and a plurality of stages are provided, so that the practice of adjusting the height of the fork 103 can be easily performed. Can do.

As mentioned above, although the training instrument for carrying out the cargo handling operation of the forklift 100 of the present invention has been described based on the specific embodiment, the present invention is not limited to the specific embodiment described above. It goes without saying that various modifications and improvements may be made without departing from the technical idea of the invention.
For example, in the above-described embodiment, the case 20 has a substantially square shape as a cross-sectional shape. However, the shape is not limited to this, and a rectangular shape, a circular shape, an oval shape, or the like is also applicable.

  In the above-described embodiment, the case 20 is formed of a balloon-like member that is formed into a cylindrical shape by press-fitting air into the inside. However, the case is formed of a lightweight plastic or the like. Is also possible.

  Furthermore, the dimension shown in embodiment mentioned above is an illustration, and is suitably determined according to the target forklift.

  As described above, various modifications and improvements made without departing from the technical concept are also included in the technical scope of the present invention, and this will be apparent to those skilled in the art from the description of the claims. is there.
