Description

  The present invention relates to a hook for towing heavy objects.More specifically, in river construction where emergency response is required due to sudden flood damage, etc., it is possible to make a large sandbag on site and for soil filling work. The present invention relates to a hook technology used in a small sandbag manufacturing apparatus or the like that prevents a related accident and has high work efficiency and safety.

  Sandbags are made of a sealed and durable bag filled with earth and sand, etc. Stacked sandbags to form a wall to prevent water outflow and to block or reinforce dykes Is what you do. The size of sandbags varies from about 10 kg to about 2 tons. Conventionally, when making a large sandbag of over 1 ton, the filling material flows into the sandbag bag with a heavy machine or a hopper. The technique of letting it have been taken in. However, sandbags often cannot stand on their own, so when filling the material, a person should have a handle placed near the opening of the sandbag and work with the sandbag opening widened. Therefore, the labor burden of the contractor is large, and it is highly dangerous for people to work near heavy machinery and the like, which is also a problem in terms of work safety.

  Under such circumstances, various techniques have been conventionally proposed. For example, a sandbag manufacturing apparatus (see Patent Document 1), which is a device for making sandbags and can be made quickly and easily compared to conventional methods, has become a known technique. Specifically, a hopper for putting soil is supported at a predetermined height by a support column, a plurality of holes are provided in the bottom plate of the hopper, and a plurality of cylindrical bodies are extended downward and attached to the positions of the holes, A partition stopper is slidably attached to the position of the cylinder. A belt conveyor is disposed below the cylinder. This proposal describes that a plurality of sandbags are placed under the hopper. However, this sandbag manufacturing device is a large-scale device, and the sandbag is a device for a small sandbag that can be moved by a belt conveyor, and the large sandbag that is the subject of the present invention is manufactured locally. There is no mention of technology that facilitates work.

  In addition, a sandbag manufacturing apparatus (see Patent Document 2) that can easily fill a long sandbag bag with a simple facility is a known technique. Specifically, it is a sandbag manufacturing apparatus for manufacturing a plurality of long sandbags, and comprises a gantry on which a plurality of long sandbags are installed and a traveling hopper installed on the cradle. It is described that a plurality of long sandbags are filled with a filler by running. However, this sandbag manufacturing device is large-scale, and the hopper is a device that moves on a rail, and a technique for facilitating work when manufacturing a large sandbag that is the subject of the present invention on-site. There is no description.

  Therefore, in order to solve the problem, the present inventor has a structure capable of easily and safely filling sandbags with sand and sand when manufacturing large sandbags locally, making the hopper with an open top freely rotatable, Technical development of the "sandbag manufacturing device" has already been made based on the idea that if no structure is left on the top of the hopper, sandbags can be transported upward by heavy machinery such as UNIC. To obtain a patent (see Patent Document 3). In addition, for sandbag bags, we have received a utility model registration for the technology in which the handle is placed inside. However, although the sandbag manufacturing apparatus can be moved to a flood damage site, etc., it is considered that there are still problems in terms of downsizing and weight reduction, and the invention with the handle portion inside There is a background that led to the creation of the present invention in order to utilize it more.

  A small sandbag manufacturing apparatus 1 according to the present invention includes a base 10, a support 20 that is disposed at four corners of the base 10, and a belt that holds the sandbag B through a roller 30 provided on the top of the support 20. It is a small and transportable sandbag D manufacturing machine composed of a very simple member called a body 40, and is pulled downward from the roller 30 in a state where the contents F are accommodated in the sandbag B. The hook 50 can be easily detached from the sandbag D. Hereinafter, description will be given based on the drawings. In addition, the whole shape of the small sandbag manufacturing apparatus 1 shown by a present Example and the shape of each part are not limited to the Example described below, In the range of the technical idea of this invention, ie, the same effect | action It can change within the range of the shape and dimension which can exhibit an effect.

  The overall configuration of the present invention will be described with reference to FIGS. Fig.1 (a) is a perspective view which shows the whole structure of the small sandbag manufacturing apparatus 1 which concerns on this invention. FIG. 1B is a perspective view showing a state in which the sandbag B can be attached and the contents F can be filled. FIG. 2 (a) is an example of a conventional sandbag manufacturing apparatus, and shows a state where the bottom B4 of the sandbag bag B is separated from the ground and floats in a state where the sandbag bag B is mounted. The state where the bottom B4 of the sandbag bag B is installed on the ground with the sandbag bag B attached is shown. In the state of FIG. 2A, the contents F can be sufficiently filled in the sandbag B, but it is difficult to remove the hook 50 provided at the tip of the band body 40 because the band body 40 is pulled. is there. On the other hand, in FIG.2 (b), strong tension | tensile_strength does not work to the strip | belt body 40, and removal is easy. However, the bottom part B4 of the sandbag B is in contact with the ground, so that the side part of the bag body B1 bends, and the filling of the contents F has a problem that the bag body B1 needs to be filled while being pulled upward.

  The sandbag D ranges from about 10 kilograms to about 2 tons, but the present invention is intended for large sandbags of approximately 1 ton. However, the shape, dimensions, or materials shown below are not limited to these, and can be changed as appropriate according to the size of the sandbag B to be used and the dimensions defined by the standards, and the scope of creation of the invention In other words, the scope of the utility model right that should be referred to as the scope of the registered utility model includes the scope that is obvious to those skilled in the art.

  The small sandbag manufacturing apparatus 1 according to the present invention is a belt that holds a sandbag B via a base 10, struts 20 arranged at four corners of the base 10, and rollers 30 provided on the top of the strut 20. It is the manufacturing machine of the small and transportable sandbag D comprised from the body 40, Comprising: Hereinafter, it demonstrates for every structural member.

  The base 10 is connected firmly so that all the supporting columns 20 adjacent to each other are connected, or a part thereof is opened. In FIGS. 1A and 1B, all the supporting columns 20 are firmly fixed. Shows the state. Note that a partially opened configuration is shown in FIG. The material for the base 10 is selected in consideration of load resistance and bending strength from the specific strength. In order to reduce the weight, for example, in a steel system, it is desirable to use a high-tensile steel plate rather than a general structural rolled steel material. Although not shown in the figure, it is also effective to provide a foot protruding downward in consideration of installation in a non-flat place.

  The support column 20 has a height and strength for suspending the sandbag B in the air, and is composed of a cylindrical member that stands on the four corners of the base 10. The width is determined. Moreover, in order to adjust the height of the support | pillar 20, the height can be easily adjusted by using an opening hole, a fixing pin, etc. in the part which receives the support | pillar 20 in the base 10. FIG. In addition, the height of the support | pillar 20 must be higher than the position used as the boundary of the accommodation area | region where the content F is accommodated, and the closing area | region for closing an upper part in the state provided with the sandbag bag B in the small sandbag manufacturing apparatus 1. I must. However, if the column 20 is raised for suspension, it becomes an obstacle when the sandbag D is pulled up by a heavy machine or the like, and the whole becomes large. Therefore, in the present invention, a configuration is adopted in which the belt body 40 is folded back to ensure the length of the belt body 40 and suppress the total height of the unnecessary device. In addition, the cross-sectional shape of the support column 20 is not particularly limited, but it is desirable that the roller 30 has a structure that can rotate with respect to the support column. Note that a band fixing part 21 for fixing one end of the band 40 is provided at a substantially intermediate position of the support column 20.

  The roller 30 is a rotating member that is provided on the upper side of the support column 20 and is turned back in the direction of the belt body 40. The roller 30 is a portion to which the load of the sandbag D is applied. It is necessary to design. Further, it is desirable that the rotating roller 30 is always installed in a direction toward the center of the region surrounded by the support column 20 or that the angle can be freely changed.

  The belt body 40 is a long belt or belt whose one end is fixed to the belt body fixing portion 21 provided in the vicinity of the center of the column 20, and extends upward along the column 20 from the band body fixing portion 21. After that, it is folded downward via a roller 30 provided at the upper end of the support column 20, and has a length for hooking the hook 50 to the handle portion B2 of the sandbag B. In the case of using a material with less stretchability, it becomes more difficult to remove the hook 50 from the handle portion B2, and the period of use such as tearing is shortened due to fatigue of the material. In the case of using a highly elastic rubber material or the like, the band 40 is stretched due to the durability problem due to repeated expansion and contraction of the material or the filling state of the contents F, and the bottom B4 of the sandbag D comes to the ground. In the same manner as described above, it becomes difficult to fill the sandbag B with the contents F. Therefore, it is desirable to use a highly durable rubber-based material that can withstand a high load and suppress stretchability. For example, it is useful to use urethane rubber obtained by a reaction between polyester and isonanate.

  The hook 50 is a locking member having a general shape that has been conventionally used provided at the other end of the band 40 opposite to the band fixing part 21, and is hooked on a handle B 2 provided in the sandbag B. However, in the present invention, the hook 50 with an unlocking function is used in place of the hook 50. That is, in the present invention, the sandbag D filled with the contents F can be easily removed from the small sandbag manufacturing apparatus 1 in any of the states shown in FIGS. 2 (a) and 2 (b). The configuration is adopted.

  The sandbag B used in the small sandbag manufacturing apparatus 1 according to the present invention is composed of a bag body B1 and a handle portion B2. The bag body B1 can be used without any particular limitation as long as it has a cylindrical shape having an opening B3 at the top and a bottom B4 at the bottom. In the case of the large sandbag B, the diameter of the opening B3 may be 1 m or more, and the length from the bottom B4 to the opening B3 may be 1 m or more. It is desirable to provide the fixing part 21 with the adjusting mechanism 22. In addition, in FIG.1 (b), although the shape of cylindrical bag B1 is made into the cylinder, what is necessary is just a cylindrical shape which opening part B3 opens large in the upper part, and it can respond also to a rectangular parallelepiped or a polygonal column.

  The position adjusting mechanism 22 is capable of adjusting the fixing position of the belt body fixing portion 21 provided near the approximate center of the support column 20. For example, as shown in FIG. 1, the position adjustment mechanism 22 is fixed near the approximate center of the support column 20. Depending on the combination of the pin for use and the pin hole, a configuration having a stepwise adjustment function, a configuration that allows a free positioning with a screwed member such as a bolt, etc., which are not shown in the figure, can be considered.

  The function and structure of the hook 60 with an unlocking function will be described with reference to FIGS. FIG. 3 is a structural explanatory view illustrating the structure of the hook 60 with an unlocking function provided at the end of the band 40 on the sandbag B side. FIG. 3A shows a state where the rotation hook 66 is locked, and FIG. 3B shows a released state. FIG. 4 is obtained by filling the sandbag B with the contents F by providing the hook 60 with an unlocking function in the present invention instead of the structure that is difficult to remove with the conventional hook 50. It is shown that the structure has been changed to facilitate removal of the band 40 from the handle portion D2 of the sandbag D. 4A shows a state in which the sandbag bag B is not attached, FIG. 4B shows a state in which the sandbag bag B is attached, and FIG. 4C shows the content F in the sandbag bag B. The filled sandbag D is shown, and the entire band 40 is straightened by the load, and the bottom D4 of the sandbag D is not installed on the ground.

  FIG. 4B shows a state in which the sandbag bag B is attached to the state of the small sandbag manufacturing apparatus 1 in FIG. 4A. After this state, the operator needs to approach the filling operation of the contents F. In addition, since a dangerous work is not forced, a safe and quick filling work is possible. In addition, it is desirable to make it the structure which coat | covers the roller 30 shown in each figure of FIG. 4 so that the strip | belt body 40 may not be damaged with operation | movement of the heavy machinery in a filling operation | work. By providing such a covering member, in the state where the belt 40 is in tension, even if the belt 40 is torn or the like, an accident involving a nearby worker is prevented. As shown in FIG. 4 (c), when the load due to the sandbag D is applied to the hook 60 with the unlocking function and the belt body 40, the belt body 40 reaches the turning point that goes downward via the roller 30. In this state, it is difficult to remove the hook unless the hook 60 with the unlocking function is provided.

  The structure of the hook 60 with an unlocking function will be described. The hook 60 with an unlocking function is composed of two main bodies 61 and a rotating hook 66 that is rotatably held between them, and a lever 62 is a rotating hook protrusion 68 provided on the rotating hook 66. And the protrusion part 64 provided in the said lever 62 has a structure which switches a latching state and a cancellation | release state with a cam structure, or hold | maintains the state.

  Next, operation | movement of the hook 60 with a latch release function is demonstrated. As a procedure for attaching the sandbag bag B to the small sandbag manufacturing apparatus 1, the handle B <b> 2 of the sandbag bag B is hung on the rotation hook 66 until the rotation hook protrusion 68 exceeds the protrusion 64 provided on the lever 62. When 66 is pushed up, a fixed state is established. Next, with respect to the operation of filling the contents B in the opening B3 of the sandbag bag B and removing the sandbag D from the small sandbag manufacturing apparatus 1 after the filling is completed, a large force is required when the lever 62 is lifted upward. First, the lever 62 is detached from the main body 61, and the fixed state is released via the rotating hook rotating portion 67. At this time, since the lever 62 exerts an action of constantly pushing back the lever by the elastic member 65, the lever 62 is always locked when not operated. Therefore, it is desirable that the contact portion between the rotating hook protrusion 68 and the protrusion 64 when not removed is in surface contact perpendicular to the direction in which the force acts.

  FIG. 5 is an explanatory diagram for explaining an embodiment in the case where a configuration including the folding mechanism 24 is employed. Since the small sandbag manufacturing apparatus 1 according to the present invention has small and lightweight features as its features, it is useful that it can be more compactly deformed during storage, transportation, and the like, and enhances such convenience. For this purpose, it is desirable to employ a structure that can be housed small by providing a joint mechanism on either the base 10 or the support column 20.

  Therefore, in FIG. 5, the Example provided with the folding mechanism 24 is shown. The structure for demonstrating the installation position and function of the folding mechanism 24 is an addition of a well-known technique, and the configuration shown in FIG. There is no particular limitation as long as compact storage is possible. The embodiment shown in FIG. 5 is an example in which a folding mechanism 24 that rotates near the bottom of the support column 20 is installed and can be tilted inward and rotated to a position that is substantially parallel to the base 10. The case where the method of fixing with a fixing pin so that it does not rotate in a state is employ | adopted is shown. Although not shown in the drawings, a configuration in which the folding mechanism 24 is provided on a part of the base 10 instead of the support 20 may be adopted.

The hook 60 with an unlocking function according to the present invention efficiently and safely manufactures heavy objects such as sandbags D and facilitates movement and work, so that construction work such as river construction and bridge construction is performed. In addition, it is considered that the industrial applicability is large as an invention that contributes to a wide field such as the transportation industry.
