2. Description of the Related Art Generally, a long shaft is often used in a foundation construction machine as described above. For example,
In the ground agitation type ground improvement device, agitation shafts of several tens of meters are installed vertically. Since such a long shaft is extremely difficult to manufacture and transport as it is, it is generally divided into a plurality of parts in the axial direction and appropriately inserted at the construction site to penetrate into the ground.

Further, in recent years, various devices have been proposed for automatically connecting shafts and penetrating them. For example, in JP-A-2-243817, while the stirring shaft stored in the stirring shaft holding device section is gripped by the stirring shaft gripping device section, the stirring shaft section is swung to move the stirring shaft to the front surface of the guide frame, and sequentially. It is shown to be replenished and supplied to a fixed position. In addition, Japanese Patent Publication No. 3-4419

It is shown that it is moved horizontally to the penetration position at the same time. This device has the advantage that the two shafts can be transferred and penetrated at the same time.

[0004]

In recent years, in order to improve the efficiency of the work of penetrating the shaft, it has been desired to develop a device for penetrating three or more shafts in one direction at the same time.

Here, in each of the devices disclosed in the above publications, the shaft is gripped by the tip of a turning member such as an arm, and the shaft is transferred by the turning of the turning member.
Although it is possible to supply a small number of shafts such as two or two, when supplying a large number of shafts of three or more at once, the strength of the swiveling member must be increased until the weight of these shafts can be withstood. In addition, the weight increase due to the reinforcement cannot be avoided. In addition, a large space is required for the turning, which greatly hinders downsizing of the device. Further, if a large number of shafts are swiveled at one time, the device is likely to lose its balance, which may impair the stability of the machine.

In view of such circumstances, the present invention provides a shaft penetrating device capable of stably simultaneously supplying a plurality of shafts and adding and penetrating them while suppressing an increase in weight and size of the entire device. The purpose is to do.

The upper frame 24 and the guide frame 25 of the shaft accommodating device 14 extend forward from the shaft penetrating and extracting device 18 to a position where the upper frame 24 and the guide frame 25 reach the portal frame 90 after passing through the penetrating position.

Next, the procedure of shaft penetration by this excavator will be described. In addition, in the following description, as shown in FIG. 1, the first penetration of the excavation shaft 16 is completed and only the upper portion thereof is the ground 1
0, and the shaft penetrating and extracting device 18
The work contents from the state where the elevating housing 92 is pulled up to the uppermost position will be described.

First, the turning hydraulic cylinder 44 shown in FIG.
To move the rod carrier 26 along the guide rail 25 in a state in which the lever 40 is contracted to direct the lever 40 to the position shown by the two-dot chain line in the figure, and the lifting hydraulic cylinder 36 is contracted to pull up the lifting bracket 38. The shaft storage device 14 is stopped at a position directly above the excavation shaft 16 stored in the frontmost row (the rightmost row in FIGS. 1 and 2). Then, after extending the elevating hydraulic cylinder 36 and lowering the elevating bracket 38, extending the rotating hydraulic cylinder 44 and directing the lever 40 downward, the hook portion 40a of the lever 40 is connected to the connecting member 19. Engage with the ears 19c. From this state, the hydraulic cylinders 36 for raising and lowering are again contracted to raise the raising and lowering brackets 38, whereby all the front row excavating shafts 16 interconnected by the connecting members 19 can be simultaneously pulled up, whereby The engagement between each excavation shaft 16 and the support base 21 is disengaged, and the ear portion 19c of the connecting member 19 is pulled up from the support portion 20a of the support frame 20 to support each excavation shaft 16 in a suspended state by the rod carrier 26. be able to.

Next, by running the rod carrier 26 along the guide rails 25, the excavation shafts 16 are moved forward in the suspended state, and the excavation shafts 16 are moved.
The rod carrier 26 is stopped at the time point when reaches the position below each chuck 98 in the elevating housing 92 (that is, the position above the already penetrated excavation shaft 16). As a result, all the excavating shafts 16 are simultaneously inserted into and extracted from the shaft penetrating and extracting device 1
It was supplied while moving in parallel to the penetration position of No. 8.

After this supply, the elevating winch is operated to lower the elevating housing 92 to a position where each chuck 98 reaches the upper end 16a of each excavating shaft 16 held by the rod carrier 26. At this time, each of the excavating shafts 16 is held by the rod carrier 26 in a state where the upper end 16a of the excavating shaft 16 is exposed upward.
Can be connected to. After this connection is completed, the rotating hydraulic cylinder 44 is contracted to release the holding of each excavation shaft 16 by the lever 40, and the rod carrier 26 is retracted to the shaft storage device 14 side.

Next, the lower end portion 16 of the excavation shaft 16 currently held by the chuck 98 is operated by the operation of the lifting winch.
The elevating housing 92 is lowered to a position where b reaches the upper end portion 16a of the first row excavating shaft 16 that has already penetrated, and the lower end portion 16b and the upper end portion 16a are connected to each other. After connection,
By operating the excavation motor 96 in the forward rotation direction,
At the same time as driving and rotating, the lifting winch is actuated to further lower the lifting housing 92, so that each excavation shaft 16 can be replenished and penetrated.

After that, the rod carrier 26 is positioned above the excavating shaft 16 in the second row from the front, and the same operation as described above is repeated to advance the penetration while successively adding the excavating shaft 16. You can

When the excavation shafts 16 are to be pulled out after the penetration, the reverse operation to the above may be performed. That is, the excavation shaft 16 is pulled up from the ground 10,
The respective excavation shafts 16 may be housed in the shaft housing device 14 while disconnecting the connections between them.

According to this excavator, the following effects can be obtained.

Since the excavation shafts 16 are moved in parallel on a row-by-row basis and are simultaneously supplied to the penetration position by traveling of the rod carrier 26 along the guide rails 25, the excavation shafts 16 can be stably transferred. You can Further, even if five pieces are supplied at the same time, the load on the strength of each member is small, and thus the weight increase due to the reinforcement can be suppressed. Furthermore, the space required for transferring the excavation shaft 16 is also smaller than that of the swivel type, and the overall size of the device is not increased.

The rod carrier 26 holds each excavation shaft 16 such that the upper end portion 16a thereof is exposed upward, and the guide rail 25 is extended to a position where the guide rail 25 passes through the penetration position and reaches the front end of the portal frame 90. ,
The excavation shafts 16 and the chucks 98 of the elevating housings 92 can be directly connected to each other while the rod carrier 26 is traveling to the position corresponding to the penetration position. In particular, in this embodiment, the excavating shafts 16 in each row are connected to the connecting members 19
Since they are interconnected with each other, it is possible to hold all the rows of excavating shafts 16 at the same time only by holding the left and right ears 19c of the connecting member 19.

While the excavation shaft 16 is being penetrated,
It is possible to retract the rod carrier 26 to hold the next excavation shaft 16, and by such an operation, the work efficiency can be improved and the required time can be shortened.

Since all the excavation shafts 16 are stored in an upright state, the storage space is small, and even if the shaft length of the excavation shafts 16 is increased to reduce the number of shaft additions, the above-mentioned storage is kept. It does not invite an increase in space.

Further, in the apparatus of this embodiment, the elevating housing 92 can be supported by the guide rails 95 so as to be able to elevate in a stable state, and the guide rails 95 are located on the opposite side of the shaft accommodating device 14 when viewed from the elevating housing 92. Since it is provided at the right position in FIGS. 2 and 7, the traveling rod carrier 26 and this rod carrier 26
The excavation shaft 16 held at the position does not interfere with the guide rail 95, and smooth shaft transfer can be ensured.

Next, a second embodiment will be described with reference to FIGS. In this embodiment, one row of the excavating shafts 16 is directly gripped by the rod carrier 26 side.

Specifically, an elevating block 38 'is mounted on a guide frame 34 similar to that of the above embodiment so as to be able to ascend and descend, and a rod 36a of an elevating hydraulic cylinder 36 similar to that of the above embodiment is mounted on this elevating block 38'. It is connected.
The left and right elevating blocks 38 'are connected to each other via a connecting frame 50 having a U-shaped cross section as shown in FIG. 10, and a clamp lever 54 is attached to the connecting frame 50. The clamp levers 54 are provided at positions corresponding to the left and right sides of the five excavating shafts 16, respectively, and are rotatable about the vertical pins 52 fixed to the connecting frame 50. Has been done. The middle portions of the clamp levers 54 which are paired with each other are connected by a hydraulic cylinder 56 for clamping, and the hydraulic cylinders 56 for clamping are expanded and contracted so that the left and right clamp levers 54 have lower flange portions on the excavating shaft 16. The position immediately below 16c is clamped, and the left and right clamp levers 54 are opened so that the excavation shaft 16 is opened.

Even in such a structure, by moving the rod carrier 26 while holding each excavation shaft 16 by each clamp lever 54, all the excavation shafts 16 in one row can be simultaneously conveyed. However, as shown in the first embodiment, if the ears 19c of the connecting member 19 for interconnecting the excavating shafts 16 are held on the rod carrier 26 side, only one holding portion is required on each side. There is an advantage that the structure of the rod carrier 26 is further simplified.

The present invention is not limited to the above embodiments, but the following modes can be adopted as examples.

(1) In the present invention, regardless of the number of storage rows of the excavating shafts in the storage arrangement direction, it may be appropriately set according to the scale of the device.

(2) In the above embodiment, the excavating shafts 16 that are simultaneously penetrated are arranged in a complete straight line, but in the present invention, the excavating shafts 16 do not necessarily have to be in a straight line. Of course, for example, the positions may be slightly shifted in the storage arrangement direction so that they simultaneously penetrate. In addition, a plurality of excavation axes 16
May be arranged in an arc shape having a large radius of curvature so as to penetrate simultaneously. In this case, the excavation shafts 16 may be arranged in an arc shape in each row of the shaft storage device 14.

(3) In the above embodiment, the elevating bracket 38 and the elevating block 38 'are moved up and down with respect to the traveling frame 28 to raise and lower each excavation shaft 16 simultaneously with respect to the support base 21. Alternatively, it is also possible to engage and disengage the support base 21 and the lower end portions 16b of the respective excavation shafts 16 by raising and lowering the support base 21 side while holding the respective excavation shafts 16 on the rod carrier 26 side. Is. However, if the excavation shaft 16 is lifted or lowered by elevating the elevating bracket 38 or the elevating block 38 'as described above, the excavation shaft 1 can be constructed with a simpler structure.
There is an advantage that 6 can be taken out from the support base 21 or can be lowered onto the support base 21.

(4) In the present invention, the specific structure of the lifting support member and the lifting guide member does not matter. For example, instead of the gate-shaped frame 90, a pipe-shaped leader 60 as shown in FIG. 11 is erected, and a pair of left and right guide pipes 62 extending in the vertical direction is fixed to the leader 60 via a mounting plate 61. A semicircular guided portion 64 fitted to the outer surface of the guide pipe 62 is fixed to the lifting housing 92 side so that the lifting housing 92 moves up and down while being guided by the guide pipe 62. May be. Also in this case, the leader 60 and the guide pipe 62 are provided at a position on the opposite side of the shaft housing device 14 when viewed from the elevating housing 92, so that the leader 60 and the guide pipe 6 are provided.
It is possible to avoid interference between the rod carrier 26 and the rod carrier 26.

(5) The present invention can be widely applied to a device for penetrating while connecting shafts to each other, and can be applied to various penetrating devices such as a ground improvement device and a boring device.

[0051]

As described above, according to the present invention, the shafts are accommodated in the shaft accommodating means by arranging the shafts in the penetrating direction and the accommodating direction, and the row of shafts arranged in the penetrating direction is exposed at the upper end thereof. A large number of shafts are held because the shafts are held by the transfer means, and the transfer means are run along a forward-backward traveling guide member provided in the shaft housing means so that the shafts are translated. At the same time, there is an effect that it can be stably supplied to the penetration position of the penetration means.
Moreover, since the mechanical load on each member during the transfer is small, the weight increase due to the reinforcement can be suppressed, and the space required for transferring the shaft is small, so that the overall size of the device can be suppressed.

Since the traveling of the transfer means and the holding of the storage shaft by the transfer means can be performed in parallel with the shaft penetration work, the work efficiency is good and the work time can be shortened. . Moreover, since all the shafts are stored in the upright state in the shaft storing means, the storage space can be small, and the shaft length of the shaft can be increased without increasing the storage space and the number of times of addition can be reduced. It is possible to

More specifically, in the apparatus according to claim 2,
Since the shafts lined up in the penetrating direction are connected by the connecting member and both ends thereof are held by the holding portions of the transfer means, compared to the structure in which all the shafts are directly held on the transfer means side, the holding portion This has the effect of reducing the number of cells and simplifying the structure.

Further, in the apparatus according to the third aspect, the elevating member of the penetrating means can be stably supported by the elevating support member via the elevating guide member, and the elevating guide member is viewed from the elevating member. Since it is provided at the position opposite to the storage means, there is an effect that interference between the traveling transfer means and the shaft held by the transfer means and the elevating guide member can be avoided, and good shaft conveyance can be maintained.

Further, in the apparatus according to the fourth aspect, by raising and lowering the raising and lowering body in the transfer means with respect to the traveling body, it is possible to simultaneously lift or lower the respective shafts held by the raising and lowering body. There is an effect that it can be carried more smoothly.
