Description

[Detailed description of the invention] The present invention relates to a lifting device for cargo handling, and more specifically, it is a transporting device used as an auxiliary device to transport bag cargo, etc. stacked in multiple tiers in bulk in the stacked state. This relates to a hanging tool that hangs from four points.

Conventionally, in order to transport bags filled with cement, fertilizer, etc., the bags were stacked on pallets in multiple tiers without falling apart, then bundled together, and then left as they were.
Generally, the bag cargo is loaded together with the pallet onto a truck or ship, and the bag cargo is unloaded together with the pallet at the destination.

That is, the pallet is used as an auxiliary tool for bulk transportation, and the pallet that has been used for transportation is usually collected and reused.

However, when transporting a large amount of bag cargo, etc., a large number of pallets are required, and since the pallets themselves are bulky and heavy, the effort and cost required to recover them is considerable. There was a problem with it.

In order to solve these difficulties, many sheet-type conveyors have recently been proposed as auxiliary tools for bulk conveyance of multi-bag cargo, etc., in place of the above-mentioned pallets.

FIG. 1 shows an example of such a carrier, and the figure shows its unfolded state.

In the figure, reference numeral 1 indicates a rectangular body cloth made of a resin sheet that is slippery and strong, such as a fiber sheet such as polypropylene or polyethylene, and a slit 2 is provided in the center along the longitudinal direction. .

Reference numeral 3 indicates a pair of hangers sewn to protrude from both ends of the body cloth 1 so as to sandwich the slit 2, and the hangers 3 are made of the same material as the body cloth 1 or made of a sheet material having strength as a hanging belt. The oblong band is sewn to the back side of the trunk cloth 1 so that the entire weight of the bag cargo is uniformly applied to the trunk cloth 1 during cargo handling.

In addition, a pair of hangers 3 are provided at each end of the trunk cloth 1, so that a hook of a crane or the like can be hung on each hanger 3 during cargo handling.
This is to achieve horizontal balance of bag cargo stacked in multiple tiers by point suspension.

Reference numeral 4 indicates reference lines provided at regular intervals in the width direction of the central region of the body cloth 1, within which the bag cargo or the like is placed.

Note that the distance between the pair of reference lines 4 is determined according to the standards of commercially available pallets and the like.

Slightly inside the pair of reference lines 4, a puller 5 for opening the opening of the slit 2 is attached to the body cloth 1.
It is sewn to the body cloth 1 so as to protrude from both ends of the body.

The pull-out handle 5 is formed by stitching a belt-like sheet made of the same material as the body cloth 1 or having strength as a hanging belt to the back side of the body cloth 1 in a crossed manner.

Therefore, when a tensile force is applied to the puller 5 to widen the cracks in the slit 2, a uniform force is applied to the center portion of the body cloth 1 on which the bag cargo, etc. is placed. .

Reference numeral 6 indicates a tie string provided at one end of the body cloth 1 so as to sandwich the slit 2, and is used when packing bag cargo.
This knot string 6 is attached to a knot ring 7 provided opposite to the other end of the body cloth 1.
The bags are tied together to pack the cargo.

In addition, as another conveyance sheet body, the above-mentioned body cloths are sewn together in a cross shape, a slit is provided in the center of one body cloth along its longitudinal direction, and further, both ends of this one body cloth are sewn together in a cross shape. Some have a structure in which a pair of hanging handles are provided at the top, and puller handles are provided at both ends of the other body cloth.

According to the conveyance sheet body configured as described above, the bag cargo etc. are stacked in multiple stages in the central part of the trunk cloth 1,
It is designed to be packed using a trunk cloth 1.

During cargo handling work, a sling is passed through each of the above-mentioned lifting hands 3, such as a rope, etc., and the objects are bundled together and hung on a hook of a crane, etc. When unloading work is carried out, the above-mentioned sling is passed through each of the above-mentioned pulling hands 5. The sheets are bundled together and hung on a hook of a crane or the like through a rope, and the pullers 5 are pulled upward at the same time to widen the slits 2 and remove the sheet body from the bag cargo, etc. By pulling it out from below, it is possible to unpack the bag cargo, etc., in its multi-tiered packaging form.

By the way, in the cargo handling and unpacking operations of such transport equipment, the ropes used for the slings may be hung depending on the situation.
It is conceivable that the horizontal balance of the transport equipment may be lost during cargo handling, and since the puller is located at the bottom in the packing mode for this transport, the sling that is passed through the puller during unloading is not connected to the rope. They tended to hang diagonally from crane hooks, causing damage to bag cargo, etc.

This kind of loss of horizontal balance and damage to the bag cargo occurs because a lifting hand or a pulling hand is attached to one hook of a crane or the like.

Therefore, the most important thing to prevent such horizontal imbalance and damage to bag cargo is to avoid hanging the lifting hands and pullers diagonally. Load-hanging hooks may be hung on the frame body at approximately the same intervals as the distance between each hanger when the transport device is packed, and the lifting or pulling hands of the transport device may be hung on the load-hanging hooks. However, in the case of a carrier like the one shown in Figure 1, the lifting hand and the puller are vertically separated from each other in the packing state, so when unpacking, the hook for lifting the load hung on the puller and the puller are separated. There was a risk that the bags would be damaged due to rubbing against the packaged bags.

The present invention was developed in view of this point of view, and allows for stable cargo handling and unpacking operations using a transport device, and also enables unpacking work to be carried out without damaging bag cargo, etc., which are packaged in the transport device. The purpose is to provide a hanging device.

The gist of the present invention is that it is used for transporting bag cargo, etc. stacked in multiple tiers in bulk in the stacked packaging state. A conveyance device that can be pulled out from under the bag cargo, etc. and unpacked in its packaging form by expanding a slit formed at the bottom using a puller hand,
In the hoisting device, which is lifted through the hoisting hands provided at four locations, the hoisting device includes a rigid frame body horizontally suspended from a hook of a crane or the like via a cable member, and a rigid frame body that is spaced apart from the frame body, respectively. 4 to be hung from the hanger
A set of load-hanging hooks are suspended from the frame at the same location as the load-hanging hooks, and a ring-shaped portion formed at the tip of the load-hanging hook is hung on the load-hanging hook through the pull-out hand. Equipped with four pairs of long auxiliary ropes,
At least one set of the load-hanging hook and the auxiliary rope is provided, and the gap between each set of load-hanging hook is
The hanger is characterized in that the gap is approximately equal to the gap between the respective hangers.

The present invention will be described below based on embodiments shown in the drawings.

FIG. 2 shows an embodiment of the hanging device according to the present invention.

In the figure, reference numeral 8 denotes a rigid frame formed of a rigid member, such as a pipe material, and wire ropes 9 are provided at each of its four corners for suspending the frame 8 from a hook of a crane or the like. ing.

Since each wire rope 9 has the same length, the frame 8 can be suspended from a hook of a crane or the like with stable horizontal balance.

Also, from the frame 8, four hanging ropes 1 each having the same length are connected.
0 is hung, and four load hanging hooks 11at, 1lbt, 11C911d are provided at the lower ends of each of the hooks.

By the way, these load hanging hooks lla, 11b, llc
, lld are for hanging a transport sheet body as shown in FIG. The distance between lla and load hanging hook llb is
The distance is approximately equal to the distance between the pair of hangers provided at the end of the body cloth described above.

Reference numeral 12 denotes a long auxiliary rope that is hung from the same place as the hanging rope 10, and a loop 13 is formed at the tip of the rope. Pass it through your hand, and then hook the ring 13 to the load hanging hook 11a.

11b, llc, and lld, respectively.

According to the hanging device having the structure described above, the load-hanging hooks are suspended from the frame at approximately the same intervals as the distance between the hangers of the conveyor sheet body, so that each hanger of the conveyor sheet body is By hanging these load-hanging hooks, the horizontal balance of the transport sheet will always be maintained stably, and furthermore, cargo handling operations can be carried out by simply hanging the load-hanging hooks on the hanger, so slinging is easy. This can now be done even if the operator is not an expert in the field.

In addition, since the puller is located almost directly below the hanger of the transport sheet body in the packing state, it is possible to pull the puller upward directly using the auxiliary rope 12, thereby preventing damage to the bag cargo material, etc. The unpacking work was now possible without any problems.

Furthermore, there is a hook 11a for hanging the load when unpacking.

11b, llc, and lid do not need to be lowered to the position where they can be hung on the puller of the transport sheet body shown in Fig. 2, so once the transport sheet body is lowered onto the pallet, unpacking work can be carried out immediately. Increased efficiency.

In this example, the frame body is suspended from a hook of a crane or the like using a wire rope, but the structure is not limited to this, and a chain or the like may also be used. Although it is suspended from the frame via a chain, it is not limited to this, and a chain or the like may also be used.

Furthermore, in this embodiment, one conveyance sheet body is lifted by a set of four load-hanging hooks, but in order to be able to lift two conveyance sheet bodies in parallel, two load-hanging hooks are used as shown in FIG. As shown in the figure, two sets of four sets of load-hanging hooks and four sets of auxiliary ropes may be provided on the rigid frame.

As described above, according to the present invention, it is possible to carry out stable loading and unloading operations using the carrier as an auxiliary tool instead of transporting bag cargo, etc. using pallets, as well as unpacking work without damaging the bag cargo, etc.; This has the excellent advantage that the work can be easily carried out by hooking the carrying device onto the hanger, etc., and its usability is great.
