Description

The present invention relates to a hanging string support for supporting a loop-shaped hanging string provided on a bag such as a sandbag while maintaining a ring shape, and a method for lifting the bag.

Conventionally, as a restoration measure work after the slope collapse, a large number of bag materials for rooting, which are filled with filling materials such as chestnut stones, are placed in the middle of the slope to temporarily receive earth and sand or boulders from the upstream side. Although the method is being used, the slope at the work site may cause a secondary disaster, so for safety reasons, it is desirable to unmanned the work of installing the bag material for rooting at the target position.
In order to unmanned the installation work of the bag material for rooting, the work of hooking a hook etc. on the hanging string provided on the bag to lift the bag body and transport it to a predetermined position on the slope is performed in the unmanned area. It is necessary to perform it by remote control.
By the way, in order to hook the hook, it is necessary to secure a space between the bag body and the hanging string so that the hook can be inserted. That is, it is necessary to stand on its own with the hanging string spread out.
Therefore, a space for inserting a hook by attaching a magnet to the tip of the attachment of a heavy machine that lifts and transports the bag, attaching an iron piece or a hanging string with a magnet to the bag, and lifting the hanging string by magnetic force. Has been proposed (see, for example, Non-Patent Document 1 and Patent Document 1).

Japanese Unexamined Patent Publication No. 2014-234277

However, in the method of securing a space for inserting the hook into the hanging string using the above magnet, not only the attachment at the tip of the heavy machine needs to be replaced with a special gripping device equipped with a magnet, but also the hanging string It was also necessary to change to one with an iron piece or a magnet attached.

The present invention has been made in view of the conventional problems, and provides a hanging string support and a method for lifting a bag body, which can secure a space for inserting a hook or the like into the hanging string with a simple configuration. The purpose is.

The present invention is a hanging string support tool that supports a loop-shaped hanging string provided on the bag body in a state of being lifted from the bag body, and has a base mounted on the upper part of the bag body and the said. A support member for supporting the hanging string and a fixing member for fixing the hanging string to the support member are provided, the support member includes a plurality of rod-shaped members, and two of the plurality of rod-shaped members are One end is fixed to the base, the other end projects upward from the base, and the other ends are connected to form two sides of the upper surface of a triangular prism having the surface formed by the base as a side surface. Then, two of the remaining rod-shaped members (excluding the two rod-shaped members from the plurality of rod-shaped members) have one end fixed to the base and the other end upward from the base. The other ends of the triangular prism are connected to each other to form two sides of the lower surface of the triangular prism, and the remaining rod-shaped members (excluding the four rod-shaped members from the plurality of rod-shaped members). One of them connects the connecting points of the rod-shaped members to which the other ends are connected to each other to form the triangular prism, and the fixing member has the hanging string in an unfolded state. Is fixed to the support member.
As a result, the hanging string can be made to stand on its own in an unfolded state, so that the bag body can be lifted and transported without using a heavy machine equipped with a special gripping device.
The "opened state" means that the parts of the hanging string 3a (3b) are not in contact with each other, as in the hanging string 3a (3b) shown by the thick solid lines in FIGS. 3A and 3B. , A state in which a space is formed between the left and right sides of the hanging string 3a (3b), that is, a so-called loop-shaped state, and the "closed state" is the hanging string shown by the thick broken line in FIG. 3A. Like 3a (3b), it refers to a state in which the left and right sides of the hanging string 3a are in contact with each other and there is no space between the hanging strings 3a. The state of FIG. 2B can also be said to be the "opened state" because each part of the hanging string 3a is not in contact with each other. Further, the size of the space formed between the hanging strings 3a in the "opened state" is such that a hooking means provided in the lifting device for hooking the hanging string and lifting the bag body, such as a hook, can be inserted. Needless to say, that is the case.

Moreover, the members of the bar, can provide the same effect and positioned along the hypotenuse of cone with base surface plane to make the said base. In this case, the surface formed by the base is n-sided, and the rod-shaped members provided so as to project upward from the base form the slope of the n-sided pyramid.
Further, since the rod-shaped member is composed of an elastic member, even if the hanging string support is once crushed by stacking the bag materials, the shape is restored to a ring shape by removing the upper bag material. Therefore, bag materials can be stacked and transported. Further, since the shape is maintained in a ring shape even after installation, the bag material can be easily replaced or removed .

Further, the present invention is a method for lifting a bag body by using the hanging string support according to any one of claims 1 to 4 , wherein the filling material is stored in the bag body. And the step of pulling out the binding string provided on the bag body for closing the opening of the bag body and closing the opening, and the lower portion of the pulled out binding string of the bag body. A step of binding with a rope for squeezing, a step of lifting each of the drawn out binding strings from the bag body and forming a loop, and attaching the loop-shaped binding string to the hanging string support as a hanging string. The present invention includes a step of hooking the attached loop-shaped hanging string to lift the bag body.
As a result, not only is it unnecessary to use a heavy machine equipped with a special gripping device, but also it is not necessary to prepare a new hanging string, so that the bag body can be lifted efficiently.

The outline of the present invention does not enumerate all the necessary features of the present invention, and subcombinations of these feature groups can also be inventions.

Embodiment 1.
1 (a) and 1 (b) are views showing the first embodiment, in which 1 is a bag body manufacturing frame and 2 is installed in a bag body support frame 1 and inside a chestnut stone or the like. The root-hardening bag body (hereinafter referred to as a bag body) containing a filling material (not shown), 3a to 3d, was attached to the upper side of the bag body 2 on the opening 2k side of the bag body support frame 1. The hanging string 10 is a hanging string support installed on the upper part of the bag body 2, 4 is a rope for squeezing the mouth connecting the lower side of the opening 2k of the bag body 2, and 5 is provided by a lifting means (not shown) for hanging. It is a hooking means for hooking the strings 3a to 3d.
As the hooking means 5, a hook, a claw of a bucket, or the like is used.
As shown in FIG. 1 (b), the hanging string support 10 includes a base 11 mounted on the upper portion of the bag body 2, a support member 12 for supporting the hanging strings 3a to 3d, and the hanging string 3a to 3d. Is provided with a bundled wire band 13 as a fixing member for fixing the support member 12.
The base 11 is a frame-shaped member having a square view in a plan view, which is formed by connecting four rods 111 to 114 at their respective ends.
The support member 12 includes five rod-shaped support pieces 121 to 125.
The support pieces 121 and 124 extend diagonally upward from both ends of the bar 114 constituting one side of the base 11, and are connected at the upper ends, and the support pieces 122 and 123 form sides facing the bar 114. It extends diagonally upward from both ends of the bar 112 and is connected at the upper end. The support piece 125 is parallel to the rod members 111 and 113 constituting the base 11, and connects the connecting portion of the support pieces 121 and 124 and the connecting portion of the support pieces 122 and 123.

The bar 112 and the support pieces 122, 123 form the upper surface of a triangular prism having a square side surface formed by the bar members 111 to 114 of the base 11, and the bar 114 and the support pieces 124, 121 form a triangular prism. It constitutes the lower surface.
Further, the bar 111 and the support pieces 121, 122, 125 form one side surface (hereinafter, referred to as a front support surface 12a) of the other two side surfaces of the triangular prism, and the bar 113 and the support piece 123, 124, 125 constitute the other side surface (hereinafter, referred to as the rear support surface 12b) of the other two side surfaces of the triangular prism.
As the material constituting the bar members 111 to 114 and the support pieces 121 to 125, steel wire, wood, resin, or the like can be used. In short, any material may be used as long as it has a rigidity that does not deform when the hanging strings 3a to 3d are fixed.
The cable tie band 13 fixes the hanging strings 3a to 3d in a spread state on the support member 12.
The material constituting the base 11 and the support member 12 is particularly limited as long as it is a material having rigidity such as steel wire, wood, or resin that fixes the hanging strings 3a to 3d and does not deform. It is not something that is done.

Next, a method of lifting the bag body 2 will be described.
In this example, the binding string 3 for closing the opening 2k of the bag body 2 is used as the hanging strings 3a to 3d.
As shown in FIG. 2A, the binding string 3 has a ring shape in which one string is alternately passed through the opening 2k side of the bag body 2 on the front side and the back side, and then the ends are joined to each other. The filling material is stored inside the bag body 2 in a state where the opening 2k of the bag body 2 is widened.
As shown in FIG. 2B, after the filling material is stored in the bag body 2, the portions of the binding string 3 on the front side are evenly pulled out to the upper part, so that the opening 2k of the bag body 2k is provided. Close.
Each of the drawn binding strings 3 becomes a ring-shaped hanging string 3a to 3d.
After closing the opening 2k of the bag body 2, the lower part of the drawn out binding string 3 of the bag body 2 is tied with the rope 4 for mouth squeezing, so that the bag body 2 can be tilted. Even if the binding string 3 is loosened, the filling material inside is prevented from coming out of the bag body 2.
Next, as shown in FIGS. 3A and 3B, each of the drawn binding strings 3 is lifted from the bag body 2 and formed into a loop shape, and the loop-shaped binding strings 3 are used as hanging strings 3a to 3d. It is attached to the hanging string support 10.
Specifically, as shown in FIG. 3A, after fixing the upper portion of the hanging string 3a to both ends of the support piece 125 using the bundle wire band 13, as shown in FIG. 3B, By fixing the root side to the lower side of the support pieces 121 and 122 using the cable tie 13 and fixing the middle part to the upper side of the support pieces 121 and 122, the hanging string 3a was spread over the front support surface 12a. Fix in the state.
The order in which the hanging string 3a is fixed to the support pieces 121, 122, 125 is not limited to this. First, the root side and the intermediate portion of the hanging string 3a are fixed to the support pieces 121, 122, and then. The upper side may be fixed to the support piece 125 or the like.
Like the hanging string 3a, the hanging string 3b is also fixed in a spread state on the front support surface 12a.
The hanging strings 3c and 3d may be fixed in a spread state on the rear support surface 12b in the same manner as the hanging strings 3a and 3b (see FIG. 1A).
Finally, the bag body 2 can be easily lifted by hooking the loop-shaped hanging strings 3a to 3d attached to the hanging string support 10 with a hooking means 5 such as a hook to lift the bag body 2. Can be done.
Although all the hanging strings 3a to 3d may be attached to the front support surface 12a, considering the balance of the hanging string support 10 after attaching the hanging strings 3a to 3d, the hanging string 3a is as in this example. , 3b are preferably fixed to the front support surface 12a, and the hanging cords 3c, 3d are preferably fixed to the rear support surface 12b.
Further, the number of hanging strings is not limited to four, and may be six or eight. That is, the number of hanging strings may be appropriately determined depending on the size, weight, and the like of the bag body 2.
Further, as the hanging string, it is not always necessary to use the binding string 3 for closing the opening 2k of the bag body 2. For example, the binding string 3 has only a function of wrapping around the opening 2k of the bag body 2 to ensure that the opening 2k is closed, and a ring-shaped hanging string that is hooked on the hooking means 5 is separately provided as a bag. It may be provided near the opening 2k of the body 2.

In the first embodiment, the support pieces 121 to 125 constituting the support member 12 are arranged along the sides of the triangular prism having the base 11 as the side surface, but as shown in FIG. 4A, the support pieces are arranged. 121-124 may be arranged along the hypotenuse of a quadrangular pyramid having a bottom surface on the base 11.
In this case, as shown in FIG. 4B, the hanging strings 3a and 3b may be fixed in a spread state on the slope of the quadrangular pyramid formed by the rod member 111 and the support pieces 121 and 122. Although the figure is omitted, the hanging strings 3c and 3d are fixed in a spread state on the slope of the quadrangular pyramid formed by the rod member 113 and the support pieces 123 and 124.
Further, as shown in FIG. 5A, the support pieces 121 to 123 may be arranged along the hypotenuse of a triangle having a bottom surface on the base 11. In this case, as shown in FIG. 5B, all the hanging strings 3a to 3d are attached to the slope of the quadrangular pyramid formed by the bar 111 and the support pieces 121 and 122, but constitute other slopes. Since the supporting side functions only as a reinforcing material, it is preferable to use a pyramid or a frustum having four or more slopes from the viewpoint of stability.
That is, considering the balance of the hanging string support 10 after attaching the hanging strings 3a to 3d, the hanging strings 3a and 3b and the hanging strings 3c and 3d are attached like the quadrangular pyramid shown in FIG. 4 (a). It is preferable to fix it on different slopes.

Further, in the first embodiment, the hanging string support 10 is arranged outside the hanging strings 3a to 3d, but the hanging string support 10 may be arranged inside the hanging strings 3a to 3d.
For example, when the hanging string support 10 is a quadrangular pyramid as shown in FIG. 4 (a), as shown in FIGS. 6 (a) and 6 (b), the hanging strings 3a to 3d are respectively of the base 11. It passes under the bar 112 and the bar 114 and is fixed to the hanging string support 10 at the apex 12z of the quadrangular pyramid. In this way, when the hanging string support 10 is arranged inside the hanging strings 3a to 3d, the roots of the hanging strings 3a to 3d are the bar member 112 and the bar member under the weight of the hanging string 3a to 3d. Since it is sandwiched between the hanging string support 10 and the bag body 2 by the 114, the hanging strings 3a to 3d can be fixed to the hanging string support 10 with one bundle wire band 13.
Further, when the hanging string support 10 is a triangular prism as shown in FIG. 1 (b), as shown in FIG. 7 (a), the hanging strings 3a to 3d are attached to the bar 112 and the bar 114 of the base 11. Pass through the lower side and fix it to the support piece 125 forming the side of the triangular prism parallel to the bar 111 and the bar 113, or as shown in FIG. 7 (b), the hanging strings 3a to 3d are attached. It may be fixed to the support piece 125 by passing through the lower side of the bar member 111 and the bar member 113.
When the hanging strings 3a to 3d are passed under the bar 112 and the bar 114 of the base 11, the hanging strings 3a to 3d can be fixed at two or more places of the support piece 125, so that the hanging strings 3a to 3d can be suspended. There is an advantage that the space of the loop formed by the strings 3a to 3d can be widened.
Further, when the hanging string support 10 is a triangular pyramid as shown in FIG. 5 (a), as shown in FIG. 7 (c), the hanging strings 3a to 3d are attached to two of the rods 111 to 113. It may pass through the lower side of the bar and be fixed to the hanging string support 10 at the apex 12z of the triangular pyramid.

Further, as the hanging string support 10, as shown in FIGS. 8A and 8B, the support pieces 121 projecting upward from the central portion on the rods 112 and 114 facing each other of the base 11, respectively. , 122 may be provided and the hanging strings 3a to 3d may be fixed to the support pieces 121 and 122. The support pieces 121 and 122 do not necessarily have to be orthogonal to the base 11, and as shown in FIGS. 8C and 8D, a line segment connecting the midpoint between the bar 112 and the bar 112 is formed. It may be arranged so that it has two sides of a triangle as a base.
Further, also in this case, the hanging string support 10 is arranged inside the hanging strings 3a to 3d, and the hanging strings 3a to 3d are passed under the rods 112 and 114 and fixed to the support pieces 121 and 122. You may.
In short, the hanging strings 3a to 3d are widened so that the ring-shaped hanging strings 3a to 3d can secure a space for inserting the hooking means 5 for hooking the hanging strings 3a to 3d such as hooks and bucket claws. Any configuration may be used as long as it is fixed to the support member 12 in this state.

Embodiment 2.
In the first embodiment, the hanging strings 3a to 3d are fixed to the support pieces 121 to 125 of the support member 12, but as shown in FIGS. 9A to 9C, the support member 12 is composed of an elastic member. At the same time, the two side surfaces 12a and 12b including the support piece 125 of the triangular prisms constituting the hanging string support 10 are formed into a mesh, and the hanging strings 3a to 3d are sandwiched and fixed by the meshed side surfaces 12a and 12b. May be good.
A plurality of mesh-like side surfaces 12a extending in a direction parallel to the support piece 125, connecting the support pieces 122, 123, 125 of the support member 12, the rod member 112 of the base 11, and the support piece 122 and the support piece 123. The lateral reinforcing piece 126 and a plurality of vertical reinforcing pieces 127 extending in a direction parallel to the support piece 122 connecting the support piece 125 and the bar member 112 of the base 11, and the mesh-like side surface 12b is formed of a mesh-like side surface 12b. Support pieces 121, 124, 125 of the support member 12, rod 114 of the base 11, and a plurality of lateral reinforcing pieces 128 extending in a direction parallel to the rod 125 connecting the support piece 121 and the support piece 124. It is composed of a plurality of vertical reinforcing pieces 129 extending in a direction parallel to the support piece 121, which connects the support piece 125 and the rod member 114 of the base 11.
Further, on the upper side of the mesh-like side surfaces 12a and 12b, an opening 12k having a size into which the hooking means 5 such as a hook or a claw of a bucket can be inserted is provided, and the hooking means 5 is inserted from the opening 12k. Then, by hooking the hanging strings 3a to 3d, the bag body 2 can be easily pulled up.

When fixing the hanging strings 3a to 3d to the mesh-like side surfaces 12a and 12b, first, the hanging strings 3a to 3d are spread, the hanging strings 3a and 3b are temporarily fixed to one of the mesh-like side surfaces 12a, and the other side surface 12b. Temporarily fix the hanging strings 3c and 3d to. After that, as shown in FIG. 9B, the hanging strings 3a to 3d are sandwiched between the hanging strings 3a to 3d with the net-like side surfaces 12a and 12b closed, and the hanging strings 3a to 3d are sandwiched between the hanging strings 3a to 3d. , 12b may be fixed from the outside.
Further, in this example, the side surfaces 12a and 12b are made into a mesh, and the angle with the extension direction of the support piece 125, which is the inclination of the support pieces 121 to 124 constituting the side surfaces 12a and 12b, is supported small on the base 11 side. One piece 125 is enlarged. As a result, the net-like side surfaces 12a and 12b are more easily deformed, so that the work of fixing the hanging strings 3a to 3d becomes easy.

In this way, if the hanging string support 10 is made of an elastic member, even if the shape of the hanging string support 10 is crushed by stacking the bag bodies 2, the shape can be restored by removing the upper bag body 2. Since the bag body 2 is formed in a ring shape, the bag body 2 can be stacked and transported, and the bag body 2 can be replaced. Needless to say, the elastic member constituting the hanging string support 10 is made of a material having rigidity such that the hanging strings 3a to 3d are fixed and not deformed.
As the elastic member, for example, a steel cord or the like can be used. Further, in recent years, high-strength and high elastic modulus fibers such as ultra-high molecular weight polyethylene fibers and polyarylate fibers, which have been attracting attention as substitutes for fishing tackle and reinforcing bars, may be woven into a rod shape.
The base 11 may also be made of an elastic member.
Further, even if the support member 12 (or the base 11 and the support member 12) of the first embodiment is composed of an elastic member, the same effect as that of the first embodiment can be obtained.

Embodiment 3.
In the first and second embodiments, the hanging strings 3a to 3d are fixed to the support member 12 by using the fixing member 13 such as the bundle wire band, but as shown in FIGS. 10A and 10B, the support is supported. The member 12 is composed of two support pieces 61 and 62 erected at the center of two rod members 112 and 114 corresponding to each other of the base 11, and the base 11 of the support pieces 61 and 62 is a member. Storage grooves 61m and 62m for storing the hanging strings 3a to 3d are formed at the opposite ends, and the hanging strings 3a to 3d are stored in the storage grooves 61m and 62m to widen the hanging strings 3a to 3d. In this state, it may be fixed to the support member 12.
As shown in the figure on the right side of FIG. 10B, the storage grooves 61m and 62m communicate with the introduction groove 63a, which is slightly wider than the diameter of the hanging strings 3a to 3d, and the introduction groove 63a, respectively. It is provided with a storage groove 63b having a groove width capable of storing the hanging strings 3a to 3d of the book.
When the hanging strings 3a to 3d are stored in the storage grooves 61m and 62m, the hanging strings 3a to 3d in the expanded state for storing the hanging strings 3a to 3d in the storage grooves 61m and 62m are introduced one by one. If the hanging strings 3a to 3d are stored in the storage groove 63b via the storage groove 63b, the hanging strings 3a to 3d can be fixed to the support member 12.
Also in this case, the hanging string support 10 is arranged inside the hanging strings 3a to 3d, and the hanging strings 3a to 3d are passed under the rods 112 and 114 to store the support pieces 61 and 62. It may be stored in the grooves 61 m and 62 m.
