Description

The present invention relates to an auxiliary tool for forming a scaffold for a transport vehicle.

Harvest vegetables (heavy leafy vegetables such as lettuce, Chinese cabbage, cabbage, heavy root vegetables such as garlic, onions, carrots, and potatoes, and other vegetables) in the field, and the agricultural products are harvest boxes (plastic boxes, cardboard boxes, etc.). ). When transporting a harvest box filled with agricultural products in this way, a plurality of stages are stacked and transported on a pallet directly placed on a loading platform such as a light truck.

Although it depends on the physique of the worker, it is relatively easy to load the harvest boxes with less than a certain number of stages from the bottom. However, when loading more than a certain number of harvest boxes from below, it is difficult to carry out the stacking work while standing on the ground on the side of the loading platform. It is conceivable to provide scaffolding at a predetermined height in order to stack more than a certain number of harvest boxes, but it is complicated and it may be difficult to provide scaffolding on unstable feet (ground).

A truck equipped with a mechanism capable of holding the side tilt plate (side tilt) in a horizontal state inside the loading platform is also known (see Japanese Patent Application Laid-Open No. 2003-291818), but the above mechanism is installed in a truck already owned. It's difficult to do.

It is preferable that the upper plate contact member and the lower plate contact member are rotatably attached to the insertion portion main body. As a result, when a downward force is applied to the protruding portion of the auxiliary tool main body while the insertion portion main body is inserted into the insertion port of the pallet, the upper plate contact portion comes into contact with the lower surface of the upper plate of the pallet. By contacting the lower plate contact portion with the upper surface of the lower plate of the pallet on one end side of the upper plate contact portion, the scaffold forming auxiliary tool can be easily and surely fixed. On the other hand, by rotating the upper plate contact portion and the lower plate contact portion so that the upper plate contact surface and the lower plate contact surface are parallel to each other, the insertion portion can be easily attached to and detached from the pallet insertion port. Can be done.

The scaffolding forming member may have a detachable portion that is detachably attached to the protruding portion. Thereby, when the scaffolding assisting tool is not used, the scaffolding forming member can be separated from the assisting tool main body.

The scaffolding forming member may have a substantially horizontal locking portion for locking the side tilt plate or the rear tilt plate of the transport vehicle below the attachment / detachment portion. As a result, with the insertion part of the auxiliary tool body inserted into the insertion port of the pallet, the attachment / detachment part of the scaffolding forming member is attached to the attachment / detachment part of the auxiliary tool body, and the side tilt plate or the rear tilt plate is engaged by the locking portion. By stopping, the side tilt plate or the rear tilt plate can be supported substantially horizontally, and the side tilt plate or the rear tilt plate can be used as a scaffold.

The upper surface of the scaffold forming member is provided as the scaffold. As a result, by inserting the insertion portion of the auxiliary tool main body to which the scaffold forming member is attached into the insertion port of the pallet, a scaffold is formed by the upper surface of the scaffold forming member, and the scaffold is used on the pallet, for example, a harvest box or the like. Can be loaded. Further, after being transported to a desired position, for example, a forklift claw (fork) is inserted into the insertion port of the pallet on which the load is mounted, and the pallet on which the load is mounted can be loaded and unloaded.

In the scaffold forming auxiliary tool, the auxiliary tool main body protrudes from the loading platform of the transport vehicle toward both sides, and each has protrusions at both ends to which the scaffold forming member is attached, and the scaffold forming member It is preferable to have a detachable portion that is detachably attached to the protruding portion and a locking portion that is provided below the detachable portion and that locks the side tilt plate of the transport vehicle that is substantially horizontal. As a result, the scaffolding assisting tool easily and surely forms scaffolding adjacent to both sides of the loading platform by attaching scaffolding forming members to both ends of the assisting tool body protruding from the loading platform toward both sides. be able to.

As described above, the scaffolding auxiliary tool can easily and surely form a scaffolding in the vicinity of the loading platform.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

[First Embodiment]
<Outline of overall configuration>
As shown in FIGS. 1 and 2, the scaffolding assisting tool 1 according to the embodiment of the present invention is a device for forming a scaffolding on the side of the loading platform 101 of the transport vehicle 100. In the description of the present embodiment, the scaffolding assisting tool 1 is fixed by using the pallet 150 mounted on the loading platform 101 of the transport vehicle 100. Further, as an example of the transport vehicle 100, a light truck having a side tilt plate 103 on the side of the loading platform 101 and a rear tilt plate 105 behind the loading platform 101 will be described as an example. The side tilt plate 103 and the rear tilt plate 105 are rotatably connected to the loading platform 101 via a hinge 107. In the following description, a scaffolding using the side tilt plate 103 will be described as an example.

As shown in FIGS. 1 to 5, the scaffolding assisting tool 1 is detachably fixed to the upper surface side of the loading platform 101 with one end protruding from the loading platform 101 of the transport vehicle 100 toward the left side. It includes a tool body 10 and a scaffold forming member 50 for forming a scaffold attached to the one end of the auxiliary tool body 10 and fixed adjacent to the loading platform 101. In the following description, "front" refers to the front (upper side of the paper in FIG. 2) of the transport vehicle 100 to which the scaffolding assisting tool 1 is mounted during normal traveling (forward), and "rear". Refers to the opposite side of the front (lower side of the paper surface in FIG. 2), and the "left-right direction" may refer to the horizontal direction perpendicular to the front-back direction (left-right direction of the paper surface in FIG. 2). Further, the one end side (left side in FIGS. 1 to 5) may be referred to as the front end side, and the opposite side of the one end side (right side in FIGS. 1 to 5) may be referred to as the rear end side.

<Auxiliary tool body>
As described above, the scaffolding assisting tool 1 forms a scaffolding by using the insertion port 151 of the pallet 150 placed on the loading platform 101. The auxiliary tool main body 10 of the scaffolding auxiliary tool 1 has an insertion portion 11 to be inserted into the insertion port 151 of the pallet 150, and the above-mentioned one end protruding laterally from the loading platform 101 as described above, and the above-mentioned insertion. It has a protruding portion 31 protruding from the mouth 151.

(Insert part)
As shown in FIGS. 3 to 5, the insertion portion 11 includes a rod-shaped insertion portion main body 13 and an upper plate contact member 15 having an upper plate contact surface 15a that contacts the lower surface of the upper plate 150a of the pallet 150. A lower plate contact member 19 having a lower plate contact surface 19a that contacts the upper surface of the lower plate 150b of the pallet 150 on one end side of the upper plate contact surface 15a is provided. The upper plate contact member 15 and the lower plate contact member 19 are rotatably attached to the insertion portion main body 13, and the relative angles between the upper plate contact surface 15a and the lower plate contact surface 19a and the insertion portion main body 13 are changed. It is provided as possible.

The specific configuration of the insertion portion 11 is not particularly limited, and the design can be changed as appropriate. However, in the present embodiment, the insertion portion main body 13 is made of a square tubular steel material. Further, the upper plate contact member 15 is made of an upper plate contact member main body 16 made of an inverted U-shaped steel material that opens downward and an elastic member such as rubber fixed to the upper surface of the upper plate contact member main body 16. The upper plate contact surface constituent member 17 is provided, and the upper surface of the upper plate contact surface constituent member 17 constitutes the upper plate contact surface 15a (see FIGS. 3 to 5). Since the upper plate contact surface 15a is formed of the elastic member in this way, the state of fixing the auxiliary tool main body 10 to the insertion port 151 of the pallet 150 can be maintained more accurately. The lower plate contact member 19 is a lower plate contact member main body 20 made of a U-shaped steel material that opens upward, and a lower plate made of an elastic member such as rubber fixed to the lower surface of the lower plate contact member main body 20. The lower plate contact surface 19a is formed by the lower surface of the lower plate contact surface constituent member 21 having the contact surface constituent member 21. Since the lower plate contact surface 19a is formed of the elastic member in this way, the state of fixing the auxiliary tool main body 10 to the insertion port 151 of the pallet 150 can be maintained more accurately. Further, as described above, the insertion portion 11 does not make linear contact with the upper plate 150a and the lower plate 150b of the pallet 150, but rather has surfaces (upper plate contact surface 15a and lower plate contact surface 15b). ), It is possible to prevent the pallet 150 from being destroyed by fixing the insertion portion 11. In particular, since the upper plate contact surface 15a and the lower plate contact surface 15b are made of elastic members, the insertion portion 11 is fixed. It is possible to more accurately prevent the destruction of the pallet 150 due to the above.

More specifically, the configurations of the upper plate contact member 15 and the lower plate contact member 19 will be described more specifically. The upper plate contact member 15 is located on the rear end side of the insertion portion main body 13 in the axial direction of the rod-shaped insertion portion main body 13. It is pivotally supported by a shaft 12 arranged vertically and horizontally. The lower plate contact member 19 is shafted on a shaft 12 arranged vertically and horizontally in the axial direction of the rod-shaped insertion portion main body 13 on the tip side of the shaft 12 on which the upper plate contact member 15 is pivotally supported. It is supported. As a result, the relative angles between the upper plate contact surface 15a and the lower plate contact surface 19a and the insertion portion main body 13 can be changed.

The upper plate contact surface 15a and the lower plate contact surface 19a are parallel to the axial direction of the insertion portion main body 13, and the vertical distance between the upper plate contact surface 15a and the lower plate contact surface 19a is reduced. (See FIG. 3), the insertion portion 11 can be easily and surely inserted into the insertion port 151 of the pallet 150, and the insertion portion 11 can be easily and surely detached from the insertion port 151 of the pallet 150. On the other hand, the upper plate contact surface 15a and the lower plate contact surface 19a are in a state of being inclined with respect to the axial direction of the insertion portion main body 13, and the upper plate contact surface 15a and the lower plate contact surface 19a are in the vertical direction. As the distance increases (see FIGS. 4 and 5), the upper plate contact surface 15a comes into contact with the lower surface of the upper plate 150a of the pallet 150, and the lower plate contact surface 19a comes into contact with the upper surface of the lower plate 150b of the pallet 150. The auxiliary tool main body 10 can be easily and surely fixed to the pallet 150 by abutting.

(Protruding part)
The protruding portion 31 is continuously provided from the insertion portion main body 13 toward the tip end side (left side of the loading platform 101 (see FIGS. 1 and 2 and the like)). In the present embodiment, the protruding portion 31 is made of the same steel material as the insertion portion main body 13. That is, the protrusion 31 and the insertion portion main body 13 are provided by one rod-shaped steel material, and the protrusion 31 and the insertion portion main body 13 are arranged in a straight line (substantially the same height).

<Scaffolding member>
As shown in FIGS. 6 to 9, the scaffolding forming member 50 is a locking portion 53 that locks the detachable portion 51 that is detachably attached to the projecting portion 31 and the side tilt plate 103 of the transport vehicle 100 substantially horizontally. The locking portion 53 is provided below the attachment / detachment portion 51. Specifically, the attachment / detachment portion 51 is provided with a mounting hole 51a into which the protrusion 31 of the auxiliary tool main body 10 is inserted and mounted, and the locking portion 53 is a support portion 53a that supports the side tilt plate 103 from below. have. The term "substantially horizontal" includes not only a completely horizontal state but also a state that can be used as a scaffold. Further, in FIGS. 6 to 9, X means a traveling direction of the transport vehicle, Y means a horizontal direction orthogonal to X (horizontal direction of the transport vehicle), and Z means a vertical direction.

The specific configuration of the scaffold forming member 50 is not particularly limited, and the design can be changed as appropriate. However, in the present embodiment, the scaffold forming member 50 is an inverted U-shaped steel material that opens downward. It has a mounting member 55 made of. By inserting the protruding portion 31 into the opening of the mounting member 55, the scaffolding forming member 50 is attached to the protruding portion 31. That is, the mounting hole 51a is formed by the mounting member 55. Further, the mounting member 55 and the protruding portion 31 are provided with a pin hole 55a for the scaffolding forming member and a pin hole for the protruding portion at corresponding positions, respectively (see FIGS. 6 and 7 (for the pin hole for the protruding portion). (Not shown)). By mounting the pin 60 in the pin hole 55a of the mounting member 55 and the protruding portion 31 (see FIGS. 1 to 3), the fixed state of the mounting member 55 to the protruding portion 31 is maintained. The pin hole 55a for the scaffold forming member is provided on one end side (left side in FIG. 7) of the attachment / detachment portion 53 with respect to the support portion 53a (support member 59 described later). As a result, even when a retaining member such as a snap pin is arranged below the pin 60, the side tilt plate supported by the support portion 53a does not get in the way.

Further, the scaffolding forming member 50 has a pair of front and rear pillar members 57 made of an L-shaped steel material in a plan view that is fixed to the front and rear of the mounting member 55 and extends downward (FIGS. 6 to 9). reference). The scaffolding forming member 50 has a support member 59 made of an inverted L-shaped steel material fixed below the pair of pillar members 57. The support member 59 is fixed to a surface on the tip end side of the pair of pillar members 57, and has a bent portion that bends from the fixed portion toward the opposite side on the tip end side and extends horizontally, and the support member 59 of the support member 59. The locking portion 53 is configured by the bent portion.

<Advantage>
In the scaffolding auxiliary tool 1, the auxiliary tool main body 10 is fixed to the upper surface side of the loading platform 101 on which a certain number of stages (three stages in FIG. 1) of harvest boxes are stacked, and the auxiliary tool main body 10 projecting from the left side of the loading platform 101. By attaching the scaffolding forming member 50 to the projecting portion 31 of the above and supporting the side tilting plate 103 by the scaffolding forming member 50, the scaffolding is easily and surely formed adjacent to the loading platform 101 by using the side tilting plate 103. Can be done. Therefore, as shown in FIG. 1, even when the three-stage harvest box 130 is stacked on the pallet 150 on the loading platform 101, the operator uses the side tilt plate 103 as a scaffolding from the lower stage from the lower stage. The above harvest boxes 130 can be easily stacked, and a desired number of harvest boxes can be stacked. The fixed number of steps for using the scaffolding auxiliary tool 1 is appropriately changed depending on the height of the loading platform 101, the height of the harvest box, the physique of the worker, and the like. Further, since the scaffolding assisting tool 1 can form a scaffolding without touching the ground, the transport vehicle 100 can be carried in the state where the scaffolding is formed (the state in which the scaffolding assisting tool 1 is used). It can be run and moved. After the stacking work as described above is completed, the scaffolding auxiliary tool 1 can be removed by separating the insertion portion 11 from the insertion port 151 of the pallet 150.

In particular, in recent years, forklifts and pallets have been widely used in the field of physical distribution for labor saving, so that the scaffolding auxiliary tool is preferably used. In addition, since the problem of handling the harvest box containing the harvested product is remarkable at the site of the harvesting work of agricultural products, the workplace of the producer, and the shipping site, the scaffold forming auxiliary tool is more preferably used.

In addition, after the harvest box 130 is stacked on a pallet placed on the ground near a transport vehicle that has entered a farm road, a control road (provided in the field), etc., this pallet can be placed on the loading platform by a forklift. It is conceivable, but since forklifts are expensive, there is a problem in terms of cost, and there are also problems in securing people who can work forklifts and whether or not they can work in forklifts, so at harvesting sites of agricultural products, etc. The scaffolding aid is preferably used.

Further, conventionally, a worker has been raised on the loading platform to stack harvest boxes 130 having a height higher than the height at which loading work from the ground has become difficult, and when raised with shoes, the loading platform, pallet or harvest box 130 is raised. Since there is a risk of getting dirty with mud, shoes are changed when the worker goes up on the loading platform, but this work is extremely complicated. Even in this case, in order to stack all the harvest boxes 130 to a desired number of stages, there is no scaffolding space on the loading platform at the final stage. Therefore, the scaffold forming auxiliary tool is more preferably used in such a work site.

Using the formed scaffold, it is possible to go up to the scaffold of the scaffold forming auxiliary tool 401 of FIG. 13 and perform various operations at a higher position.

Further, for example, a scaffold is formed from the rear to the front of the transport vehicle 100 by the scaffold forming auxiliary tool 301 of FIG. 12, the scaffold forming auxiliary tool 1 of FIGS. 1 to 9, and the scaffold forming auxiliary tool 401 of FIG. However, it is possible to provide scaffolding in a stepped manner on the side of the transport vehicle 100.

Further, in the above embodiment, the auxiliary tool main body is detachably fixed to the upper surface side of the loading platform in a state where one end of the auxiliary tool main body protrudes only toward the left side of the loading platform of the transport vehicle. However, the present invention is not limited to this, and the auxiliary tool main body is detachably fixed to the upper surface side of the loading platform in a state where one end of the auxiliary tool main body protrudes from the loading platform of the transport vehicle toward at least one of both sides and the rear. The design can be changed as appropriate if it is possible. For example, as shown in FIG. 14, those having protrusions protruding from both sides of the loading platform are within the range intended by the present invention, and those projecting from only the rear of the loading platform are also intended by the present invention. It is within the range.

Further, in the above embodiment, the scaffolding assisting tool is fixed by using the insertion port 151 of the pallet 150, but the present invention is not limited to this. For example, as shown in FIG. 14, it may be placed and fixed directly on the loading platform 101. The auxiliary tool main body 510 of the scaffolding auxiliary tool 501 of FIG. 14 projects from the loading platform 101 of the transport vehicle 100 toward both sides, and the projecting portions 531 at both ends to which the scaffolding forming member 50 of FIGS.
