Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an auxiliary device for slinging a container to be lifted such as a mesh pallet or a box pallet.
[0002]
[Prior art]
When a wire, a rope, a hanging chain, a belt, a hook, or the like is slung on a heavy object and lifted and moved by a crane, a winch, or the like, a sling assisting device or an assisting device is often used.
As this auxiliary tool, generally, a pad for hanging a heavy object to be hung on a corner, a wrapping around a rope surface, a pillow, a hook, a wedge, and the like are well known (for example, Non-Patent Document 1). reference).
[0003]
For large heavy objects, an auxiliary device for slinging has been developed which includes a carrier made of a face material supporting a bottom portion thereof and a horizontal hanging rod hanging on an upper end of a hanging ring hooked on hooks on both sides thereof. (For example, see Patent Document 1).
[0004]
Further, in the case of hanging a container to be lifted such as a mesh pallet having an accommodation space therein, a gondola type having front and rear frames A, A as shown in FIG. 6 has been put to practical use. In this apparatus, the bottom of the mesh pallet B is supported by the lower rods a1 and a1 of the front and rear frame members A and A, and the upper rods a2 and a2 of the front and rear frame members pulled on the upper surface of the mesh pallet are suspended by a suspension ring. It is designed to hang on a hook D via C. The side rods a3, a3 of the left and right frame bodies A, A support side surfaces of the mesh pallet B.
[0005]
Another example of a mesh pallet assisting device that is actually used on site is a support frame E that covers the upper surface of the mesh pallet as shown in FIG.
In this example, the wire F is hung on the recess formed below the leg b of the mesh pallet B, the upper part of the wire F is hung on the hanging hook D, and the narrowed wire intermediate portion f is attached to the support frame. It is intended to be supported. As a result, the wire F does not directly hit the upper edge of the mesh pallet B, and deformation and breakage of the mesh pallet B can be prevented.

[0007]
[Problems to be solved by the invention]
However, the aid described in Non-patent Document 1 is not enough to suspend a container-type heavy object such as a mesh pallet or a box pallet. Further, the one described in Patent Document 1 is not suitable for suspending a heavy object of a container type.
[0008]
The gondola type auxiliary device shown in FIG. 6 is not only heavy as a whole, but also because the lower rod a1 of the frame body A is located outside the legs of the pallet B, so that the upper rod a2 is closed. On the other hand, the lower rod a1 is in an open state, and there is a problem in terms of safety during lifting.
[0009]
Since the support frame E shown in FIG. 7 has a size corresponding to the upper surface of a mesh pallet or the like, it is bulky for transportation and storage, and workability is poor. In addition, the wire F must be hooked to the recess below the leg b, and there is a risk that the wire F may be damaged by the edge of the recess.
[0010]
An object of the present invention is to provide a slinging assisting device that is lightweight, can be easily transported and stored, has high workability, and does not cause damage to a suspended object.
[0011]
[Means for achieving the object]
The present invention has the following configuration to achieve the above object.
That is, the apparatus comprises an upper support attached to the upper part of the container to be lifted and a lower support attached to the lower part of the container to be lifted. The upper support has a main body extending across the upper surface of the container to be lifted, and upper locking portions on both sides of the main body which are locked to upper edges on both sides of the container to be lifted. And a holding portion through which the four hanging ropes are respectively inserted to hold a middle portion of each hanging rope at a predetermined position without contacting the upper edge of the container to be lifted. On the other hand, the lower support is provided with a lower locking portion which is locked to the lower portion on both sides of the container to be lifted, and a fixing portion which fixes the lower end portion of each of the hanging ropes.
[0012]
The suspended object to which the present apparatus is used is not limited to a box pallet or a mesh pallet, but may be a container type having an accommodation space therein.
[0013]
The main body of the upper support may be a frame material or a face material. Desirably, it is formed by a substantially rectangular frame frame body including a pair of horizontal bars spaced at a predetermined interval and a pair of vertical bars connecting ends of the horizontal bars. The pair of horizontal rods has a length extending across the upper part of the container to be lifted, and includes the upper locking portion and the holding portion at each end. The pair of vertical rods is shorter than the upper edge of the container to be lifted and extends substantially parallel thereto.
[0014]
As the upper support main body composed of the frame, a horizontal rod and a vertical rod are connected by a pivotal support structure, and a structure that can be folded substantially linearly and expandable in a rectangular shape can be adopted. Of course, the upper support may have a fixed shape that cannot be expanded and folded.
In addition, the upper support member composed of the frame may have a structure in which two support rods cross each other in an X-shape and can be deployed and folded by pivotally supporting a central portion.
[0015]
When the container to be lifted is a mesh pallet, the upper locking portions are provided at each end of the horizontal rod of the main body, and are inserted into one mesh of the upper edge of the mesh pallet to shift the upper support in the front-rear direction. And a locking piece for preventing upward detachment.
[0016]
The holding portion may be a substantially horizontal two-stage hook member provided at each end of the main body horizontal rod. Both hook members are formed so that the openings face left and right opposite directions.
[0017]
The lower support member may be constituted by a set of lower supports.
The support includes left and right hook members that are hung on both lower edges of the container to be lifted, left and right fixing members that fix the lower ends of the hanging ropes, and fixation of the left and right hook members to each other and to the left and right. And a connecting rod for connecting the members.
Further, the lower support member may be constituted by four support fittings which are locked to lower portions on both sides of the container to be lifted. The support fitting may be locked so as to hold the legs of the lifted container. These support fittings have a fixing portion such as a shackle for fixing the lower end of the hanging rope.
The lower locking portion of the lower support member does not necessarily need to be a hook-shaped member, and depending on the content of the structure of the bottom surface of the suspended container (particularly, the floor structure), the cross section may have a simple L-shaped or U-shaped shape. It may be formed.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention will be described in detail based on illustrated embodiments.
FIG. 1 is an external perspective view showing a use state of an apparatus according to an embodiment of the present invention. FIGS. 2 and 3 are plan views of an expanded state and a contracted state of an upper support member constituting the apparatus. FIG. 4 is an external perspective view of the lower support member.
[0019]
In the figure, reference numeral 1 denotes a mesh pallet that accommodates a large number of fittings such as scaffolding connecting fittings, and 2 and 3 denote an upper support member and a lower support member constituting the present apparatus.
[0020]
The upper support member 2 is composed of two horizontal rods 21 made of a pipe material and two vertical rods 22 holding and connecting the horizontal rods 21 at a predetermined interval. The horizontal rod 21 has a length sufficient to traverse the mesh pallet 1. The vertical rod 22 has a length shorter than the upper edge of the mesh pallet 1 and extends substantially parallel thereto, and both ends 22 a are pivotally supported by the horizontal rod 21 via pin members 26.
The upper support member 2 becomes a substantially rectangular frame as shown in FIG. 2 when the vertical rod 22 is at a vertical position with respect to the horizontal rod 21, and the vertical rod 22 is at a position parallel to the horizontal rod 21. When this happens, it will be in the narrow folded state seen in FIG.
[0021]
The horizontal rod 21 has holding parts 23 at both ends. The holding portion 23 is for hooking the intermediate portion 41 of the hanging cord 4 and holding it at a predetermined position, and is composed of a horizontal two-stage hook member. As shown in FIGS. 1 to 3, the hook members are formed with openings 24 facing left and right, respectively.
[0022]
Further, upper locking portions 25 are provided at both ends of the horizontal rod 21. The upper locking portion 25 is for preventing the upper supporting member 2 from shifting along the opening edge of the mesh pallet 1 and is formed of an inward tongue. The tongue piece 25 has a width and a thickness that enter into one mesh just below the upper edge of the mesh pallet 1.
[0023]
The lower support member 3 includes a pair of lower supports 31 having the same structure. As shown in FIG. 4, each lower support 31 includes left and right side plates 32, 32, a connecting plate 33 connecting the right and left side plates 32, and a connecting rod 34. The side plate 32 is formed in a substantially L-shape, and an upward hook portion 35 is formed at the lower end of the side plate 32. The rising piece of the side plate is provided at its upper end with a shackle 36 for hooking a lifting wire, and a downward pressing claw 37 is formed inside the middle portion.
[0024]
A method of slinging using the present apparatus will be described.
First, the lower support 31 is inserted between the bottom surface on both sides of the mesh pallet and the ground. The inserted left and right lower supports 31 have the hook portions 35 of the side plates 32 engaged with the mesh on the bottom surface of the mesh pallet 1 and the holding claws 37 in the middle of the side plates with the strip-shaped edge material (angle material) at the bottom of the mesh pallet. ) 11 (see FIG. 1). The annular portion 42 of the wire rope 4 whose one end is annularly compressed is hung on the shackle 36 of the lower support 31.
[0025]
On the other hand, the upper support member 2 is attached to the open upper surface of the mesh pallet 1. The upper support member 2 is arranged in a developed, substantially rectangular frame-like state at a substantially middle portion in the width direction of the upper surface of the mesh pallet so as to cross in the left-right direction. Then, the tongue pieces 25 provided on both side ends of the horizontal rod 21 are inserted into one mesh at the upper edge of the mesh pallet.
[0026]
Next, the middle portion 41 of the suspension wire 4 fixed to the lower support member 3 is attached to the upper and lower two-stage horizontal hooks 23 of the upper support member 2. The suspending wire 4 attached through the opening 24 in the opposite direction is restricted by the inner peripheral edge of the two-stage horizontal hook 23, so that it is difficult to detach in any direction.
[0027]
In this state, the upper portion of the suspension wire 4 is hooked on the suspension hook 5, and the mesh pallet 1 is lifted. The lower end 42 of the pulled suspension wire 4 is hooked by the hook 35 of the lower support member 3 connected thereto to the angle material on the bottom surface of the mesh pallet, and the holding claw 37 is engaged with the upper edge of the outer surface of the angle material on the bottom of the mesh pallet. After being stopped, the mesh pallet 1 is stably supported. Since the left and right hook portions 35 and the pressing claws 37 are connected by the connecting plate 33, both the hook portions 35 and the both pressing claws 37 are substantially equally divided by the left and right members cooperating with each other. Support the bottom.
[0028]
The intermediate portion 42 of the suspension wire 4 is held by a horizontal hook that is the holding portion 23 of the upper support member 2 without contacting the upper edge of the mesh pallet 1. For this reason, the drawing force of the suspension wire 4 does not directly act on the mesh pallet, and deformation and breakage of the mesh pallet 1 are prevented. In addition, since the tongue piece 25 is inserted into one mesh of the mesh pallet, the upper support member 2 is not shifted in the front-rear and left-right directions due to an impact force or a swinging power during lifting or placing.
[0029]
To remove the sling, the suspending wire 4 is detached from the suspending hook 5, and the upward pulling force of the suspending wire 4 is released. The middle part 41 of the loosened suspension wire is removed from the horizontal hook 23 of the upper support member 2, and the upper support member 2 is removed from the upper surface of the mesh pallet 1. The lower support member 3 (31, 31) is pulled out from the bottom of the mesh pallet 1, and the loop 42 at the lower end of the suspension wire is removed from the shackle 36 of the lower support member 3. If necessary, the upper support member 2 rotates the vertical rod 22 to contract linearly, and transports and stores it.
[0030]
FIG. 5 is a perspective view showing a lower support member according to another embodiment of the present invention.
In this embodiment, the lower support member 130 includes four support fittings 131. The support bracket 131 is a U-shaped bent main body 132, a detachable pin member 133 for closing an opening of the main body 132, and a shackle detachably fixed to a projecting piece 134 formed on the back surface of the main body 132. 135.
[0031]
The main body 132 is formed to have a length and width sufficient to hold the legs 12 of the mesh pallet 1 from the side, and has holes for inserting the pin members 133 at the ends of both arms. After the pin member is inserted into the hole, the tip of the pin member is tightened with a nut to close the opening of the main body, and the main body 132 is engaged with the leg 12 of the mesh pallet 1.
A lower end hoop of a hanging wire (not shown) is hooked and fixed to the shackle 135.
[0032]
In this embodiment, the same upper support member as that in the above-described embodiment is used. In use, a support bracket 131 is fixed to each of the bottom legs 12 of the mesh panel 1, and a middle part of the suspension wire hooked on the shackle 135 of the support bracket 131 is similarly held by the upper support member, and the upper part of the suspension wire is held. Hang it on the hanging hook.
Since the wire is not hooked in the recess below the leg, the chance of damage to the suspension wire can be reduced.
[0033]
Although not shown, when formed by a frame, the upper support member may be constituted by two support rods crossed in an X-shape. In this case, by pivoting the X-shaped intersection, a simple structure that can be expanded and folded is provided. At both end portions of the two support rods, a holding portion and an upper locking portion similar to those in the above-described embodiment are provided.
[0034]
【The invention's effect】
According to the present invention, the following effects can be obtained.
This device has an upper support attached to the upper part of the container to be lifted and a lower support attached to the lower part, and allows the upper support to be positioned at a predetermined position without bringing the hanging rope into contact with the upper edge of the container to be lifted. The lower support is provided with a lower locking portion which is locked to the lower portion on both sides of the container to be lifted, and a fixing portion for fixing the lower end portion of the hanging rope, so that the lower support can be lifted. The container, especially the upper part thereof, can be safely lifted or moved without being deformed or broken by the pulling force of the lifting cord. In addition, simply setting the upper locking part of the upper support to the upper part of the container to be lifted and the lower locking part of the lower support to the lower part of the container to be lifted can be easily set. It can be carried out.
[0035]
In addition, the upper support member does not cover the entire upper surface of the container to be lifted, but only needs to traverse a part of the container. The lower support member has a simple structure with a lower locking portion and a fixed portion. As such, it is lightweight and does not become bulky for transportation or storage.
In particular, the upper support member employs a framework structure that can be expanded and folded, so that the upper support member is more compact and easier to handle.
[0036]
Further, by adopting the configuration of the ninth aspect to the lower support member, not only can the attachment of the lower support member be simplified, but also it can further contribute to stable support.
