Description

The present invention relates to a hanging holder.

Large blocks and the like are sometimes transported loaded onto pallets, either by being lifted by a forklift or hung by a crane. In such cases, the load on the pallet is often exposed, and it is desirable to avoid damaging the load during transport.

Patent Document 1 discloses a pallet lifting device that can lift a pallet without damaging the cargo. The pallet lifting device described in Patent Document 1 is configured with a long steel body that is inserted into the gap under the pallet and has string bodies attached to both ends that protrude from both sides of the pallet. The pallet is lifted by hoisting the string bodies with hooks.

JP 2000-143140 A

However, in the case of Patent Document 1, when the string is lifted with a hook, the string extends from both ends of the elongated body at an incline in the vertical direction toward the upper part of the center of the pallet (see Figure 2 of Patent Document 1). Because the string passes close to the cargo, in the case of bulky cargo, there is a risk that the string will hit the corners of the upper part of the cargo and cause damage to the cargo.

Therefore, one of the objects of the present invention is to provide a hanging holder that can hang a pallet without damaging the loaded cargo.

The hanging holder of the present invention comprises:
A hanging holder that suspends and holds a rectangular parallelepiped pallet on which a load is placed when the pallet is transported by a transport device, comprising:
A lower support that supports the pallet from below;
an upper support positioned above the load and held by the conveying device;
a plurality of connecting portions extending along a vertical direction and connecting the upper support portion and the lower support portion;
Equipped with.

According to the present invention, a pallet can be hung without damaging the load on the pallet.

Figure 1 is a perspective view of the hanging holder 1 when in use.

The hanging holder 1 is a holder that allows the pallet 100 carrying the load 110 to be suspended and transported by a transport device (not shown) such as a crane. Examples of the load 110 include blocks of ceramic or concrete.

First, the pallet 100 will be described. The pallet 100 has a rectangular parallelepiped shape. The pallet 100 has gaps 101 and 102 that run through it along the surface on which the load 110 is placed. The gaps 101 and 102 are parallel to each other. Note that the pallet 100 is not a dedicated pallet for the hanging holder 1. The pallet 100 may be any pallet that can be supported from below by the lower support 2 described below, such as a well-known pallet into which the tines of a forklift can be inserted.

The hanging holder 1 comprises a lower support 2, an upper support 3, and multiple connecting parts 4.

The lower support 2 supports the pallet 100 from below. The specific configuration of the lower support 2 will be described with reference to Figs. 1 to 4. Fig. 2 is a plan view of the lower support 2. Fig. 3 is a view of the lower support 2 as seen from the front. Fig. 4 is a view of the lower support 2 as seen from the side. Note that Fig. 2 is a view of the lower support 2 as seen from above in the vertical direction when the hanging holder 1 is in use, with the pallet 100 indicated by dashed lines.

The lower support 2 is formed, for example, from a steel material. The lower support 2 has a first elongated member 21, a second elongated member 22, and a third elongated member 23.

The first long member 21 is a member extending in one direction (hereinafter referred to as the length direction). The second long member 22 is a member extending in the length direction and arranged parallel to the first long member 21. The third long member 23 is a member extending in a direction perpendicular to the length direction (hereinafter referred to as the width direction) and connecting one end of each of the first long member 21 and the second long member 22. The first long member 21, the second long member 22, and the third long member 23 may be cylindrical or prismatic, or may have an H-shaped or groove-shaped cross section. The first long member 21, the second long member 22, and the third long member 23 may be hollow.

The first elongated member 21 is inserted into the gap 101 of the pallet 100. The second elongated member 22 is inserted into the gap 102 of the pallet 100. In this state, the first elongated member 21 and the second elongated member 22 have a length that protrudes from each of the two opposing sides of the pallet 100 when viewed vertically.

In FIG. 2, the first long member 21 and the second long member 22 have the same length, but the lengths of the first long member 21, the second long member 22, and the third long member 23 are not particularly limited. The first long member 21 and the second long member 22 may have the same length, but may be longer or shorter than the third long member 23. Furthermore, the lengths of the first long member 21, the second long member 22, and the third long member 23 may be different or all the same.

Lower connection parts 211, 212, 221, 222 are provided at both ends of each of the first elongated member 21 and the second elongated member 22 protruding from the pallet 100. The connecting part 4 described below is connected to the lower connection parts 211, 212, 221, 222. The configuration of each of the lower connection parts 211, 212, 221, 222 is not particularly limited as long as it is a configuration that allows the connecting part 4 to be connected. For example, if the connecting part 4 is a wire rope with a hook provided at its tip, the lower connection parts 211, 212, 221, 222 will be configured to allow the hook to be hung.

The lower connection portion 211 is provided at one end of the first long member 21 to which the third long member 23 is connected, and the lower connection portion 212 is provided at the other end of the first long member 21. The lower connection portion 221 is provided at one end of the second long member 22 to which the third long member 23 is connected, and the lower connection portion 222 is provided at the other end of the second long member 22. In the width direction, the lower connection portion 211 and the lower connection portion 221 face each other, and the lower connection portion 212 and the lower connection portion 222 face each other.

The third elongated member 23 has handholds 231, 232 provided along the width direction. The handholds 231, 232 are members that are gripped by an operator when inserting and removing the first elongated member 21 and the second elongated member 22 into and from the gaps 101, 102 of the pallet 100. Providing the handholds 231, 232 makes it easier for an operator to insert and remove the lower support 2 into and from the gaps 101, 102 of the pallet 100. The handholds 231, 232 may be provided at any position that is easy for an operator to grip when inserting and removing the lower support 2 into and from the gaps 101, 102.

The upper support 3 is formed, for example, from a steel material. The upper support 3 holds the lower support 2 via a number of connecting parts 4 at a position above the load 110 loaded on the pallet 100. The upper support 3 is also held by the conveying device via wires 120. The upper support 3 will be described with reference to Figures 1, 5, 6 and 7.

Figure 5 is a plan view of the upper support 3. Figure 6 is a view of the upper support 3 as seen from the front. Figure 7 is a view of the upper support 3 as seen from the side. Note that Figure 5 is a view of the upper support 3 as seen from above in the vertical direction when the hanging holder 1 is in use.

The upper support 3 has an outer frame 31 and an inner frame 32. The outer frame 31 is rectangular in plan view from the vertical direction and is approximately the same size as the lower support 2. The inner frame 32 is a cross-shaped frame provided inside the outer frame 31.

Four upper connection parts 311, 312, 313, 314 are provided on the underside of the upper support 3 facing the lower support 2, at the four corners of the outer frame 31. The upper connection parts 311, 312, 313, 314 are connected to the linking part 4, which will be described later. The configuration of each of the upper connection parts 311, 312, 313, 314 is not particularly limited, similar to the lower connection parts 211, 212, 221, 222.

When the hanging holder 1 is in use, the upper connection part 311 faces the lower connection part 211 in the vertical direction, and the upper connection part 312 faces the lower connection part 212 in the vertical direction. The upper connection part 313 faces the lower connection part 221 in the vertical direction, and the upper connection part 314 faces the lower connection part 222 in the vertical direction. The upper connection parts 311, 312, 313, and 314 face the lower connection parts 211, 212, 221, and 222 in the vertical direction, so that the connecting part 4 is extended in the vertical direction.

In this embodiment, the upper connection parts 311, 312, 313, and 314 are provided at the four corners of the outer frame 31, but the locations at which they are provided are not limited to the four corners of the outer frame. When the hanging holder 1 is in use, the upper connection parts 311, 312, 313, and 314 only need to be provided at positions vertically opposite the lower connection parts 211, 212, 221, and 222.

Four device-side connection parts 321, 322, 323, 324 are provided on the top surface of the upper support 3, which is the transport device side, at the four corners of the outer frame 31. A wire 120 that connects to the transport device is connected to the four device-side connection parts 321, 322, 323, 324. The configuration of the device-side connection parts 321, 322, 323, 324 is not particularly limited, similar to the lower connection parts 211, 212, 221, 222. By providing the four device-side connection parts 321, 322, 323, 324 at the four corners of the rectangular upper support 3, the upper support 3 can be suspended in a balanced manner by the transport device.

The four device side connectors 321, 322, 323, 324 are preferably provided at positions that overlap with the upper connectors 311, 312, 313, 314 in the vertical direction. In this case, the lower connectors 211, 212, 221, 222, the upper connectors 311, 312, 313, 314, and the device side connectors 321, 322, 323, 324 overlap in the vertical direction. With this configuration, when the hanging holder 1 is suspended by the transport device, the hanging holder 1 can be suspended stably in a well-balanced manner. The device side connectors may be provided in the center of the inner frame 32, and as long as the hanging holder 1 can be suspended by the transport device in a well-balanced manner, the installation positions and the number of the device side connectors are not particularly limited.

The four connecting parts 4 are, for example, stainless steel wire ropes or wire chains that connect the lower support 2 and the upper support 3, and have hooks on both ends. Each of the four connecting parts 4 connects the upper connection part 311 to the lower connection part 211, the upper connection part 312 to the lower connection part 212, the upper connection part 313 to the lower connection part 221, and the upper connection part 314 to the lower connection part 222. The lower connection parts 211, 212, 221, and 222 face the upper connection parts 311, 312, 313, and 314 in the vertical direction, so that the connecting parts 4 extend along the vertical direction. The connecting parts 4 may be rod-shaped metal members.

The length of the connecting part 4 can be changed as appropriate, but as long as the upper support 3 is positioned higher than the load 110 placed on the pallet 100 when the hanging holder 1 is in use, the length of the connecting part 4 can be changed as appropriate to suit the condition. If the connecting part 4 is a string such as a wire, the connecting part 4 may be equipped with an adjustment fitting such as a turnbuckle for adjusting the length of the wire.

The suspension holder 1 configured as described above is configured so that each component does not interfere with the load 110 placed on the pallet 100. Therefore, when the pallet 100 is suspended and transported, even if the load 110 placed on the pallet 100 is bulky, the pallet 100 can be suspended and transported without damaging the load 110.

Furthermore, the hanging of the pallet 100 using the hanging holder 1 improves work efficiency compared to hanging the pallet 100 with a string such as a wire without using the hanging holder 1. For example, when preparing to transport the pallet 100 by hanging it, the work of inserting the first elongated member 21 and the second elongated member 22 of the lower support 2 into the gaps 101, 102 of the pallet 100 is easier than passing a string through the gaps 101, 102, and therefore the work efficiency is improved.

The procedure for attaching the hanging holder 1 to the pallet 100 is, for example, to insert the first elongated member 21 and the second elongated member 22 of the lower support 2 into the gaps 101, 102 of the pallet 100. The upper support 3 is suspended by a transport device. The lower support 2 and the upper support 3 are then connected by the connecting portion 4. This procedure allows the hanging holder 1 to hold the pallet 100, making it possible to transport the pallet 100 while hanging.

(Modification)
In the above-described embodiment, the lower connection portions 211, 212, 221, 222 of the lower support 2 and the upper connection portions 311, 312, 313, 314 of the upper support 3 are in a one-to-one relationship, but the upper support 3 may further include another upper connection portion.

Figure 8 is a plan view of another example of the upper support 3. Figure 9 is a side view of another example of the upper support 3. Note that Figure 8 is a view of the upper support 3 viewed from below in the vertical direction when the hanging holder 1 is in use.

The upper support 3 further includes four spare connection parts 331, 332, 333, and 334. The four spare connection parts 331, 332, 333, and 334 have the same configuration as the upper connection parts 311, 312, 313, and 314, and are configured to allow the connecting part 4 to be connected.

In this case, when the lower connection parts 211, 212, 221, 222 of the lower support 2 face the upper connection parts 311, 312, 313, 314 in the vertical direction in the use state of the hanging holder 1, the lower connection parts 211, 212, 221, 222 are connected to the upper connection parts 311, 312, 313, 314 by the connecting parts 4. Also, when the lower connection parts 211, 212, 221, 222 of the lower support 2 face the spare connection parts 331, 332, 333, 334 in the vertical direction, the lower connection parts 211, 212, 221, 222 are connected to the spare connection parts 331, 332, 333, 334 by the connecting parts 4.

In this way, lower supports 2 of different sizes can be used for one upper support 3. Therefore, a lower support 2 according to the size of the pallet 100 can be used. Note that a lower connection part other than the lower connection parts 211, 212, 221, and 222 may also be provided on the lower support 2 side.

In the above embodiment and modified example, the lower support 2 and the upper support 3 have different configurations, but they may have the same configuration. For example, two members are prepared, each of which has an apparatus-side connection part further provided on the lower support 2. One member serves as the lower support 2 to support the pallet 100 from below, and the other member serves as the upper support 3 and is held to the conveying device via the wire 120. The two members are then connected by the connecting part 4. In this case, it is possible to reduce manufacturing costs, since it is only necessary to manufacture members with the same configuration.
