Description

  The present invention relates to an auger head stand used when an auger head is attached to and detached from an earth auger excavator. More specifically, the auger head stand of the present invention is formed in a cylindrical shape and can support the auger head inserted into the cylinder.

  Conventionally, for example, an earth auger excavator is used in a soil cement continuous wall construction method. In the standard construction method of the soil cement continuous wall method, first, cement milk is injected from the tip of the auger screw and agitated while excavating the ground with the auger screw provided in the earth auger excavator. A stress wall (for example, an H-shaped steel column) is inserted into the excavation hole filled with cement milk, and the cement milk is mixed and stirred to harden, thereby forming a continuous wall by the cement column array.

  Further, the earth auger excavator used in the above construction method is generally assembled at a construction site before use and disassembled at the construction site after use. An earth auger excavator basically has an earth auger assembly and a leader. The earth auger assembly is configured by connecting an auger rod, an auger screw, and an auger head. The leader also has a function of supporting the earth auger assembly and moving the earth auger assembly forward and backward with respect to the ground. For example, when assembling an earth auger excavator, first assemble the leader and stand upright with respect to the ground. After that, the auger rod is attached to the speed reducer provided in the leader, and the auger screw is connected to the tip of the auger rod. In addition, attach the auger head to the tip of the auger screw. At this time, the auger head is placed on the ground. Then, the reducer is operated so as to lower the auger screw from directly above the auger head placed on the ground, and the auger head and the auger screw are connected by sandwiching the auger head between the ground and the auger screw. Let Through these processes, the earth auger assembly is assembled and the earth auger excavator can be used.

  As described above, the connection between the auger head and the auger screw is performed by lowering the auger screw toward the auger head that is stationary on the ground. However, when performing this work, if the auger head is placed alone on the ground, the auger head will tilt. In other words, the auger head is designed with emphasis on the ability to bite into the ground and the verticality of the drilling hole, making it difficult to stand alone. As described above, when the auger head is tilted when the auger head and the auger screw are connected, the assembly work efficiency is lowered and the safety of the work is lowered.

  In order to solve such problems, it has been conventionally proposed to use a receiving platform for supporting the auger head when the auger head and the auger screw are connected (Patent Document 1). The conventional receiving platform is composed of a base material and a cross member that is parallel to the connecting material, and the parallel cross member supports the spiral wing part while avoiding interference with the blade part of the auger head. By placing the auger head on the top of the auger head, the auger head can be left stationary while maintaining a vertical state.

JP 2002-201662 A

  However, as described above, the conventional auger head receiving platform needs to be constructed by assembling the base, the connecting material, and the cross member, and it takes time to assemble. In addition, in the conventional auger head receiving table, the auger head must be placed so that the blade of the auger head is inserted between the parallel cross member and the connecting material. Since it has a weight that is difficult to transport, it takes time to place the auger head on the conventional auger head loading table. Also, since the conventional auger head receiving platform is for placing the auger head on the base and does not support the auger head from its periphery, some external force is applied to the auger head in the horizontal direction with respect to the ground. When it is done, it cannot resist the external force, and there is a risk that the auger head tilts after all. Furthermore, since the conventional auger head receiving platform is a combination of a base, a connecting material, and a cross member, for example, when a large force is applied in the vertical direction when connecting the auger head and the auger screw. , It was unstable that there was a possibility that the timber and cross members would collapse.

  For this reason, there is a need for an auger head stand that has a simple and robust structure and can prevent the auger head from tilting even when an external force is applied to the auger head from any direction. It has been.

Therefore, as a result of intensive investigations on the means for solving the problems of the prior art described above, the inventor of the present invention formed a stand for the auger head in a cylindrical shape and supported the auger head by the cylindrical stand. It was found that the auger head can be prevented from tilting with a simple and robust structure. Based on the above knowledge, the inventor came up with the idea that the problems of the prior art could be solved, and completed the present invention.
Specifically, the present invention has the following configuration.

The present invention relates to an auger head stand. The auger head stand is used for supporting the auger head 12 in order to prevent the auger head 12 from overturning when the auger head 12 is attached to and detached from the tip of the auger screw 11 provided in the earth auger excavator 1. The
The auger head stand of the present invention is formed in a cylindrical shape and has a stand body 21 into which the auger head 12 is inserted.
The stand main body 21 has a clearance with which the auger head 21 can be inserted into the stand main body 21 and the vertical state of the auger head 12 can be maintained with respect to the maximum width of the auger head 12.

  As described above, according to the present invention, the auger head is supported by the cylindrical stand body so as to surround the auger head. As described above, the auger head stand of the present invention basically does not need to be constructed by assembling various members, and thus can have a simple structure. Moreover, since the stand main body is formed in a cylindrical shape such as a cylindrical shape or a polygonal cylindrical shape, it has a robust structure. Furthermore, since the present invention supports the auger head so as to surround the auger head, for example, even when a large external force is applied to the auger head in the horizontal and vertical directions with respect to the ground, Can be prevented from tilting.

  The stand body 21 is preferably designed such that its minimum inner width is 100% or more and 130% or less with respect to the maximum outer width of the auger head 12. By designing the stand body with a minimum inner width of 100% or more and 130% or less with respect to the maximum outer width of the auger head 12, it is possible to stand the auger head 12 while maintaining the vertical state. .

  The auger head stand of the present invention preferably further includes one or a plurality of support plates 22. The support plate 22 is a member that is connected to the outer peripheral surface of the stand body 21 and extends in a direction orthogonal to the upright direction of the stand body 21. Thus, the stability of the auger head stand itself can be improved by connecting one or more support plates to the stand body.

  The auger head stand of the present invention preferably further includes one or a plurality of reinforcing ribs 23. The reinforcing rib 23 is a member that is connected to the outer peripheral surface of the stand main body 21 and stands up in the same direction as the upright direction of the stand main body 21. In this way, the standing state of the stand body can be reinforced by connecting the reinforcing rib to the stand body. In other words, by providing the reinforcing rib, even when a large external force is applied to the stand body, the auger head stand itself can be prevented from being tilted and the stability can be improved.

  The auger head stand of the present invention may further have one or a plurality of integrated objects in which the support plate 22 and the reinforcing rib 23 are integrated. In other words, by providing the support plate and the reinforcing rib in an integrated manner, even if a large external force is applied to the stand body, the problem of bending or breakage of the connection part of the stand body and the support plate is prevented. can do.

  The auger head stand of the present invention preferably further includes one or a plurality of inner width adjusters 24 having a predetermined width. The inner width adjuster 24 is detachably provided so as to be in contact with the inner peripheral surface of the stand main body 21 and has a function of reducing the minimum inner width of the stand main body 21.

  By attaching the inner width adjuster as in the above configuration, the minimum inner width of the stand main body 21 can be appropriately adjusted according to the maximum outer width of the auger head. For this reason, when the size of the auger head attached to the earth auger excavator is changed, it is only necessary to attach the inner width adjuster to the auger head stand, and it is not necessary to change the auger head stand to be used.

  The auger head stand of the present invention is preferably provided with a cushioning material on the grounding surface of the auger head stand and in the cylinder of the stand body 21.

  As in the above-described configuration, the auger head inserted into the stand main body can be further stabilized by providing the cushioning material in the cylinder of the stand main body. Further, since the shock absorbing material can absorb the impact when the auger screw is attached to the auger head, the wear of the connection portion between the auger head and the auger screw can be eliminated.

  In the auger head stand of the present invention, the stand main body 21 has a plurality of split cut lines 21a formed from the lower end to the upper end of the stand main body 21, and is configured to be split at the split cut lines 21a. It may be.

  If the stand main body 21 can be divided into two parts or three parts, for example, as described above, the work of removing the auger head stand after attaching the auger screw to the auger head becomes simple.

  According to the present invention, a stand for an auger head having a simple and robust structure and capable of preventing the auger head from tilting even when an external force is applied to the auger head from any direction is provided. can do.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments described below, and includes those appropriately modified by those skilled in the art from the following embodiments.
In this specification, “A to B” means “A to B”.

(1. Outline of auger head mounting process)
First, referring to FIG. 1, an outline of a process for attaching an auger head to an auger screw will be described.
FIG. 1 is a schematic view for explaining a situation where the auger head stand of the present invention is used. That is, FIG. 1 shows an outline of the work of attaching the auger head 12 to the auger screw 11 provided in the earth auger excavator 1. As shown in FIG. 1, the auger head stand 2 is used for the purpose of supporting the auger head 12 and allowing it to stand on the ground when the auger head 12 is attached to the auger screw 11 provided in the earth auger excavator 1. . Although FIG. 1 shows the state of the work of attaching the auger head 12 to the auger screw 11, the auger head stand 2 of the present invention can also be used for the work of removing the auger head 12 from the auger screw 11. .

  The earth auger excavator 1 shown in FIG. 1 is an example, and the auger head stand 2 according to the present invention can be used for attaching / detaching a known auger head to / from a known earth auger excavator. For example, as shown in FIG. 1, a general earth auger excavator 1 includes a vehicle body 16, a leader 14 connected to the vehicle body 16, and an earth auger assembly 10 supported by the leader 14. Yes. The leader 14 stands vertically to the ground to be excavated. The leader 14 is provided with a speed reducer 15, and the earth auger assembly 10 is coupled to the speed reducer 15 along the leader 14. For this reason, when the speed reducer 15 advances and retreats the leader 14, the earth auger assembly 10 moves up and down while rotating in a direction perpendicular to the ground. The earth auger assembly 10 includes a rod-shaped auger rod 13 coupled to the speed reducer 15, a spiral blade-shaped auger screw 11 coupled to the auger rod 13, and an auger head attached to the tip of the auger screw 11. 12 is the basic configuration. The auger head 12 is a cutter for ground excavation, and is provided with an uneven cutting blade at the tip on the side in contact with the ground.

  As shown in FIG. 1, when the auger head 12 is attached to the auger screw 11, first, the auger head 12 is transported while being lifted by a lifting device such as a crane and is placed in the cylinder of the cylindrical auger head stand 2. insert. The auger head stand 2 is placed on the ground with the opening of the cylinder facing upward, and the auger head 12 can be inserted through the opening. When the auger head 12 is inserted into the auger head stand 2, the auger head 12 is left stationary while maintaining the connecting portion with the auger screw 11 upward. For this reason, the auger screw 11 is lowered from directly above the auger head 12, so that the auger screw 11 and the auger head 12 can be connected safely and easily. That is, when the auger screw 11 and the auger head 12 are connected, a large force is applied in the vertical direction, but the auger head 12 is supported by the auger head stand 2 and can maintain the vertical state. Even when connected to, it is possible to maintain a stable state without tilting.

(2. Structure of the auger head stand)
Next, a specific configuration of the auger head stand according to the present invention will be described with reference to FIGS.
(2-1. First Embodiment)
FIG. 2 is a perspective view showing the auger head stand according to the first embodiment. FIG. 3A is a plan view showing the auger head stand according to the first embodiment, and FIG. It is sectional drawing which shows the state which cut | disconnected the stand for auger heads.

  As shown in FIG. 2, the auger head stand 2 has a cylindrical stand body 21 into which the auger head 12 is inserted. In the example shown in FIGS. 2 and 3, the stand body 21 is formed in a cylindrical shape. However, the shape of the auger head stand 2 is not limited to a cylindrical shape, and may be, for example, a triangular cylindrical shape, a rectangular cylindrical shape, or other polygonal cylindrical shapes. The cylindrical stand body 21 surrounds the auger head 12 so that the outer wall of the auger head 12 is in contact with the inner wall thereof. For this reason, the stand main body 21 can support the auger head 12 from all circumferential directions. That is, the stand main body 21 has a clearance that allows the auger head 12 to be smoothly inserted into the stand main body 21 with respect to the maximum width of the auger head 12 and that the auger head 12 can be maintained in a vertical state. Yes.

  The minimum inner width I of the stand main body 21 can be appropriately designed according to the relationship with the maximum outer width O of the auger head 12. Here, as shown in FIGS. 3A and 3B, the minimum inner width I of the stand body 21 is a linear distance between the inner walls of the stand body passing through the center of the shape forming the stand body 21. Means the smallest of them. Further, as shown in FIG. 3B, the maximum outer width O of the auger head 12 means the maximum width when the auger head 12 is viewed from a plane. If the value of the minimum inner width I of the stand main body 21 is too large with respect to the maximum outer width O of the auger head 12, even if the auger head 12 is inserted into the stand main body 21, the outer periphery of the auger head 12 is Since the auger head 12 does not contact the inner wall of the auger head 12, the vertical state of the auger head 12 cannot be maintained. On the other hand, if the minimum inner width I of the stand main body 21 is smaller than the maximum outer width of the auger head 12, the auger head 12 cannot be inserted into the stand main body 21. For this reason, the minimum inner width I of the stand body 21 is preferably 100% or more and 130% or less with respect to the maximum outer width O of the auger head 12. Further, the minimum inner width I of the stand main body 21 may be 101% or more and 130% or less with respect to the maximum outer width O of the auger head 12, and is particularly preferably 105% or more and 115% or less.

  As a material for forming the stand main body 21, a material capable of appropriately supporting the weight of the auger head 12 can be used. For example, the stand body 21 is preferably made of a metal such as stainless steel, steel, or copper. Further, the thickness of the wall forming the stand main body 21 can be appropriately designed so that the weight of the auger head 12 can be appropriately supported. For example, the thickness of the wall forming the stand main body 21 may be 10 mm to 200 mm, or 20 mm to 100 mm.

  As shown in FIGS. 2 and 3, one or more support plates 22 extending in a direction perpendicular to the upright direction of the stand body 21 (horizontal direction with respect to the ground) are connected to the outer peripheral surface of the stand body 21. It is good as well. The support plate 22 has a surface that is in parallel with the ground, thereby preventing the stand main body 21 from being tilted. In the example shown in FIG. 3A, four support plates 22 are provided at intervals of 90 degrees when the stand body 21 formed in a cylindrical shape is viewed from a plane. However, it is sufficient that at least one support plate 22 is provided, two, three, or four or more support plates 22 may be provided. Further, the support plate 22 may be a series that extends from the entire periphery of the stand body 21.

  Further, it is preferable that one or a plurality of reinforcing ribs 23 are provided on the outer peripheral surface of the stand main body 21. The reinforcing rib 23 is connected to the outer peripheral surface of the stand body 21 and reinforces the standing state of the stand body 21 by standing in the same direction as the upright direction of the stand body 21. In the example shown in FIG. 2 and FIG. 3B, the reinforcing rib 23 is integrated with the support plate 22, but the reinforcing rib 23 may be provided independently from the support plate 22. Good. As shown in FIGS. 2 and 3B, the reinforcing rib 23 is provided on the surface of the support plate 22 opposite to the surface in contact with the ground, and is also connected to the outer peripheral surface of the stand body 21. For this reason, the stand body 21 is supported by the reinforcing ribs 23 even when a large external force is applied to the stand body 21 on the ground and the horizontal construction method. For this reason, by providing the reinforcing rib 23, it is possible to prevent, for example, a problem that the connecting portion between the stand main body 21 and the support plate 22 is bent or damaged. 2 and 3 show an example in which the reinforcing ribs 23 are provided at three locations on each support plate 22. However, the number of the reinforcing ribs 23 is not limited to this, and may be one, for example, or may be provided at four or more.

  As shown in FIG. 2, one or more suspension portions 25 can be provided on the outer peripheral surface of the stand main body 21. For example, as shown in FIG. 2 and FIG. 3B, the suspending portion 25 is formed by drilling a round hole in a plate extending on the outer peripheral surface of the stand main body 21. Usually, the auger head stand 2 for supporting the auger head 12 has a weight that is difficult to convey by human power. For this reason, the auger head stand 2 can be transported by attaching a wire hook or the like of a crane transporter to the suspension part 25 by attaching the suspension part 25 to the stand body 21. Accordingly, it is possible to smoothly carry the auger head stand 2.

(2-2. Second Embodiment)
FIG. 4 shows an auger head stand according to the second embodiment of the present invention. FIG. 4A is a plan view of an auger head stand. FIG. 4B is a cross-sectional view showing a state cut along the line XX in FIG. FIG. 4C is a perspective view showing an example of the inner width adjuster 24 provided in the second embodiment. In the following description of the second embodiment, the description of the same parts as those of the above-described first embodiment will be omitted, and description will be made focusing on differences from the above-described first embodiment.

  As shown in FIG. 4A, the stand main body 21 is attached with one or a plurality of inner width adjusting tools 24 having a predetermined width so as to be in contact with the inner peripheral surface thereof. The inner width adjuster 24 is detachable from the stand body 21. By attaching the inner width adjuster 24 so as to contact the inner peripheral surface of the stand main body 21, the minimum inner width I of the stand main body 21 can be adjusted. Therefore, the minimum inner width I of the stand body 21 can be varied by appropriately changing the thickness of the inner width adjuster 24 and the number of inner width adjusters 24 attached to the stand body 21. FIG. 4A shows an example in which four inner width adjusters 24 are attached to the stand main body 21. The four inner width adjusters 24 are arranged at intervals of 90 degrees so as to contact the inner peripheral surface of the stand body 21 formed in a cylindrical shape. Therefore, in the example shown in FIG. 4A, the minimum inner width I of the stand main body 21 is a linear distance between the inner width adjusting tools 24 facing each other through the center of the shape forming the stand main body 21. It becomes.

  FIG. 4B shows an example in which the auger head 12 is inserted into the stand main body 21. The stand main body 21 shown in FIG. 4B and the stand main body 21 shown in FIG. 3B have the same shape. On the other hand, the auger head 12 shown in FIG. 4B has a maximum outer width O smaller than that of the auger head 12 shown in FIG. In such a case, the inner width adjuster 24 is attached to the stand main body 21. That is, as shown in FIG. 4B, the minimum inner width I of the stand body 21 is reduced by attaching the inner width adjuster 24 to the stand body 21. For this reason, the outer periphery of the auger head 12 comes into contact with the inner width adjuster 24, and thus the auger head 12 is supported while maintaining a vertical state. Thus, the auger head stand 2 can be made to correspond to a plurality of auger heads 12 having different maximum outer widths by changing the minimum inner width I of the stand main body 21 by the removable inner width adjusting tool 24. Can do. Even when the inner width adjuster 24 is attached, the minimum inner width I of the stand body 21 is 100% or more and 130% or less with respect to the maximum outer width O of the auger head 12. Is preferred.

  FIG. 4C is a perspective view showing an example of the inner width adjuster 24. In the example shown in FIG. 4C, the inner width adjuster 24 includes a cylindrical inner width adjuster main body 24a having a thickness, and a locking hook 24b attached to the inner width adjuster main body 24a. The inner width adjuster main body 24a has a function of reducing the minimum inner width I of the stand main body 21 by its thickness. The locking hook 24 b has a function of attaching the inner width adjuster main body 24 a to the stand main body 21. For example, the locking hook 24 b is locked to the stand main body 21 by being inserted through a locking hole formed in the stand main body 21. However, the shape and structure of the inner width adjuster 24 are not limited to those shown in FIG. For example, the inner width adjuster 24 may be formed in a cylindrical shape and attached to the stand main body 21 so as to contact the entire inner wall of the stand main body 21.

(2-3. Third Embodiment)
Next, an auger head stand according to a third embodiment of the present invention will be described.
FIG. 5 is a cross-sectional view of the auger head stand 2 according to the third embodiment. In the example shown in FIG. 5, the cushioning material 3 is disposed on the ground surface of the auger head stand 2 and in the cylinder of the stand body 21. A known material can be used as the buffer material 3. For example, as the buffer material 3, sawdust, sponge, expanded polystyrene, or a combination thereof can be used.

  As described above, the cushioning material 3 is spread in the cylinder of the stand main body 21, so that the auger head 12 becomes more stable when the auger head 12 is inserted into the stand main body 21. Further, even if the ground on which the auger head stand 2 is installed is a hard ground, the external force generated in the connecting operation of the auger screw 11 and the auger head 12 can be reduced by providing the buffer material 3. For this reason, for example, it is possible to prevent breakage or wear of the connecting portion of the auger screw 11 and the auger head 12 or the like.

(2-4. Fourth embodiment)
Next, a fourth embodiment of the present invention will be described with reference to FIG.
In the fourth embodiment of the present invention, the stand main body 21 has a plurality of divided cut lines 21 a formed from the lower end to the upper end of the stand main body 21. For this reason, the stand main body 21 is configured so as to be capable of being divided at the dividing line 21a.

  FIG. 6A shows an example in which split cut lines 21 a are formed at two locations on the stand main body 21. For this reason, the stand body 21 can be separated into two semi-cylindrical parts. Note that the stand main body 21 preferably has a connection fixing means 26 across the dividing cut line 21a in order to maintain the connected state of the separable portions. That is, when the auger head 12 is supported using the auger head stand 2, it is preferable to connect the separable portions using the connection fixing means 26. Although FIG. 6A shows an example in which the divided cut lines 21a are formed at two places on the stand body 21, the divided cut lines 21a may be formed at three or more places. Good. For example, when the dividing cut line 21a is formed at the stand main body 213, the stand main body 21 is divided into three parts.

  FIG. 6B shows a state where the auger head stand 2 shown in FIG. 6A is separated into two parts. As shown in FIG. 6B, the auger head stand 2 has a separable structure, so that, for example, after the auger head 12 is attached to the auger screw 11, the auger head stand 2 is easily removed. can do. That is, usually, when the earth auger assembly 10 is assembled by attaching the auger head 12 to the auger screw 11 using the cylindrical auger head stand 2, in order to remove the auger head stand 2, It is necessary to move the earth auger assembly 10 upward once. In this regard, if the auger head stand 2 can be separated and removed after the auger head 12 is attached to the auger screw 11, the auger head can be used without moving the earth auger assembly 10 upward once. The removal work of the stand 2 can be completed. For this reason, work efficiency can be improved.

  The present invention relates to an auger head stand used when an auger head is attached to or detached from an earth auger excavator. For this reason, this invention can be utilized suitably in the civil engineering and construction industry.
