[Bar material burying equipment]
As shown in FIGS. 1 to 4, the bar material embedding device 100 of this embodiment is mainly configured to include a lower vehicle body 1 and an upper vehicle body 3 that is turnably provided on the lower vehicle body 1. .

The lower vehicle body 1 is provided with a pair of left and right traveling bodies 2, 2. The traveling bodies 2 are constituted by a covering band (also called an endless track). The traveling bodies 2 and 2 roll around the wheel portion using a driving force supplied from a power source such as an engine. Thereby, the bar | burr material embedment apparatus 100 can move the ground surface GL in the direction of moving to the front, rear, left, right, or turning left, right on the spot.
The lower body 1 is provided with a blade 4 on the front side. The blade 4 is configured to be movable up and down.

The upper vehicle body 3 includes a driver's seat 5, a boom 6 provided in front of the driver's seat 5, and an engine (not shown) provided inside. An operation unit 7 for operating the boom 6 and the like is provided around the driver seat 5. Among these, an operation lever 7 a and the like are provided in front of the driver seat 5.
In the operation unit 7, using these operation levers 7 a and the like, a traveling operation of the bar embedding device 100, a lifting operation of the boom 6, an angle changing operation of the pipe insertion machine 11, and the like are performed.

  The boom 6 is made of steel that has an upwardly convex side view and has a substantially U shape. The boom 6 is pivotally supported at a position in front of the driver seat 5 of the upper vehicle body 3 so as to be swingable in the vertical direction. The boom 6 is provided with a boom cylinder 6b. And the front-end | tip part 6a of the boom 6 can be tilted up and down by the expansion-contraction of the boom cylinder 6b.

A rotating base member 8 is pivotally supported on the tip 6a of the boom 6 so as to be tiltable in the front-rear direction. A turning motor 10 is attached to the rotation base member 8. An angle-of-attack setting cylinder 9 is connected between the rotary base member 8 and the boom 6.
The angle-of-attack setting cylinder 9 adjusts the tilt angle of the rotation shaft of the swing motor 10 with respect to the tip of the boom 6 by tilting the rotation base member 8 in the front-rear direction by expansion and contraction and tilting the rotation shaft of the swing motor 10. can do. Thereby, the angle of attack α between a guide rail 12 and a ground surface GL, which will be described later, can be adjusted (see FIG. 4). The angle of attack α can be adjusted even when the boom 6 is tilted.

The turning motor 10 includes a boom side body 10a, a hydraulic rotation motor (not shown) housed in the turning motor 10, and an insertion machine side body 10b.
The boom side body 10 a is fixed to the rotary base member 8. The insertion machine side body 10b is pivotally supported by the boom side body 10a so that it can rotate 360 degrees. And the insertion machine side body 10b is comprised by the rotation drive of a hydraulic rotation motor so that rotation to the perimeter direction with respect to the boom side body 10a is possible.

  The guide rail 12 of the pipe insertion machine 11 is connected to the insertion machine side body 10b via a slide mechanism 20 and a swing mechanism 30 described later. The slide mechanism 20 has a slide cylinder 21 and a slide rod 22.

The slide cylinder 21 is supported by the boom-side body 10 a and a swing cylinder 32 constituting the swing mechanism 30. That is, one end of the slide cylinder 21 (the end portion on the distal end side of the bar 40) is supported by the telescopic rod 33 of the swing cylinder 32 via the first bracket 21a. The other end of the slide cylinder 21 is pivotally supported by the insertion machine side body 10b via the second bracket 21b.
The slide cylinder 21 extends and contracts the slide rod 22 in the longitudinal direction of the bar 40. The distal end 22a of the slide rod 22 is connected to the lower surface side of the guide rail 12 via the third bracket 21c.

When the slide rod 22 expands and contracts by driving the slide cylinder 21, the guide rail 12 connected to the tip 22a slides in the front-rear direction along the longitudinal direction.
The slide mechanism 20 of this embodiment reciprocates the guide rail 12 along the insertion direction of the bar 40. By this reciprocation, the distance between the tip of the guide rail 12 and the ground surface GL can be adjusted.

The swing mechanism 30 is provided between the guide rail 12 and the turning motor 10.
The swing mechanism 30 includes a first link portion 31, a swing cylinder 32, and a telescopic rod 33. The 1st link part 31 is being fixed to the insertion machine side body 10b, and has pivotally supported the 2nd bracket 21b of the slide cylinder 21 so that rotation is possible. Further, the swing cylinder 32 is connected to the insertion machine side body 10 b via the first link portion 31.
The swing cylinder 32 is pivotally supported by the first link portion 31 so as to be rotatable. The distal end of the telescopic rod 33 is pivotally supported by the first bracket 21a.

The swing mechanism 30 configured as described above extends and contracts the telescopic rod 33 of the swing cylinder 32. Then, the guide rail 12 tilts with the first link portion 31 as the rotation center so as to swing the head vertically between the solid line position and the two-dot chain line position in FIG.
For this reason, the angle of attack α with respect to the ground surface GL of the guide rail 12 can be adjusted by stopping the guide rail 12 at a desired angle.

The guide rail 12 is made of a long steel material. A tip guide portion 12 a for guiding the bar 40 to a desired position is provided at the tip portion of the guide rail 12.
In this embodiment, a hollow round tubular pipe member is used as the bar 40. When the bar 40 is attached along the guide rail 12, the lower end 41 of the bar 40 is mounted and guided on the tip guide 12a. The upper end portion 42 of the bar 40 is held by the rear pipe insertion machine 11.
The bar 40 is held by the tip guide portion 12 a and the pipe insertion machine 11. For this reason, even if it is tilted or rotated by the rotational drive of the turning motor 10 or the like, it will not fall off from the guide rail 12.
Therefore, the angle of the guide rail 12 can be tilted and changed to be an angle suitable for insertion while the bar 40 is attached.

Further, a roller chain 51 is rotatably provided at the center in the width direction of the guide rail 12 (see FIG. 1).
The roller chain 51 is combined with sprockets 52 and 52 that are rotatably provided at both front and rear ends. A hydraulic feed motor 50 that rotates the sprocket 52 is provided at the rear end of the guide rail 12. The roller chain 51 moves the pipe insertion machine 11 in the front-rear direction along the guide rail 12 when the sprocket 52 is rotated by the rotational drive of the hydraulic feed motor 50.

The pipe insertion machine 11 hits or presses the upper end portion 42 of the bar 40 set on the guide rail 12 while moving in the front-rear direction by the rotational drive of the roller chain 51. The bar 40 guided by the tip guide portion 12a is inserted into the ground from the lower end portion 41.
In this embodiment, the pipe insertion machine 11 is used to hit or press the upper end portion 42 of the bar 40. However, the present invention is not limited to this. For example, the upper end portion 42 of the bar 40 may be rotated so that the thread formed on the surface of the bar 40 is screwed into the ground. Further, the pipe insertion machine 11 may apply a hit while pressing the upper end portion 42 of the bar 40.

Next, the effect of the bar | burr material embedding apparatus 100 of this embodiment is demonstrated.
In the bar embedding device 100 of the embodiment configured as described above, the hydraulic oil is sent to the turning motor 10 by the operation of the operation unit 7 shown in FIG. By this rotational drive, the insertion machine side body 10b rotates relative to the boom side body 10a.
Thereby, the guide rail 12 can point the front-end | tip guide part 12a to any direction of 360 degree | times centering on this turning motor 10. FIG. Therefore, the bar 40 can be inserted by arbitrarily changing the direction of the guide rail 12 to give a desired insertion angle.

  Further, the guide rail 12 is tilted in the front-rear direction by the swing mechanism 30 as shown by the solid line position and the two-dot chain line position in FIG. Thereby, the guide rail 12 comes to stand on the ground surface GL at a desired angle.

  Furthermore, when the space | interval with the ground surface GL arises by rotation and tilting, the guide rail 12 can be moved to the longitudinal direction by driving the slide mechanism 20. Thereby, the front-end | tip of the guide rail 12 can be located in the optimal distance from the ground surface GL.

As described above, the rod embedding apparatus 100 rotates and tilts the guide rail 12 by the rotation drive of the turning motor 10 and the operations of the slide mechanism 20 and the swing mechanism 30, so as to be directed in any direction of the entire circumference. The bar 40 can be inserted at a desired angle with the insertion direction of the pipe insertion machine 11 directed.
Therefore, the degree of freedom in the direction of pipe burying increases. Moreover, the several bar 40 can also be advanced from one direction to multiple places.

[Base plate]
5-8 has shown the baseplate 60 used for the foundation construction of this embodiment.
The base plate 60 includes a base plate main body 62 having a square shape in a top view placed on the ground surface GL. The base plate main body 62 has a box shape and includes leg portions 62a at each of the four corners. Further, side surfaces 66 connecting the leg portions 62a and 62a are integrally provided on the four sides of the base plate main body 62, respectively. The base plate main body 62 has a substantially trapezoidal shape in a side view (see FIG. 6), and has a vertical cross-sectional shape in a substantially gate shape (see FIGS. 7 and 8).

The base plate 60 includes a plurality of through holes 64. The through-holes 64 of this embodiment are formed at a total of four locations, obliquely through the upper and lower surface portions, in the upper part of the position where the leg portions 62a of the base plate body 62 are provided.
The through-holes 64 are formed along the axial directions L shown in FIG. 5 along the four side surfaces 66 of the base plate in a top view. Moreover, as shown in FIGS. 6-8, the through-hole 64 is formed so that it may become diagonally by side view. The inclination angle β in the axial direction L of each through-hole 64 of this embodiment is configured to be inclined in the same direction in the circumferential direction by about 45 degrees from the vertical direction (see FIG. 7).

  Further, a cylindrical guide tube portion 64 a is formed around each through hole 64. The guide cylinder portion 64a protrudes upward from the upper surface portion of the base plate body 62. Bolt holes 64b are formed in the peripheral wall of the guide tube portion 64a. The bolt hole 64 b is inserted with a bolt member (not shown) that fixes the bar 40 inserted through the through hole 64.

  The base plate 60 thus configured is fixed to the ground surface GL by inserting the bar 40 inserted through the through hole 64 into the ground.

A mounting hole 62b is formed in the central portion of the base plate main body 62 so as to penetrate the upper surface portion vertically. The attachment hole 62b is used for connection with a pedestal or the like of a solar panel (not shown) placed on the base plate 60.
[Example of basic construction]

FIG. 9 and FIG. 10 are top views for explaining how the construction is efficiently performed by the bar material embedding device 100.
In this construction example, a base plate 60 serving as a foundation of a structure installed on the ground is fixed to the ground surface GL using a plurality of bar members 40 inserted obliquely from different directions.
That is, one base plate 60 is fixed by the four bar members 40.

  The respective bars 40 are inserted at intervals of 90 degrees on the circumference around the vertical axis 61 at the center of the base plate 60. Each bar 40 is driven toward the ground at an angle α of about 45 degrees obliquely. Since the axial direction L of the through hole 64 is inclined in the same direction in the circumferential direction, each bar 40 that is driven while being guided by one of the through holes 64 spreads in different directions a to d ( 16 to 18), there is no crossing or interference in the ground.

For easy understanding, first, (1) and (2) in FIG. 9 show a state in which two bar members 40 are advanced from one direction to one base plate 60.
First, the bar material embedding device 100 is moved and moved to the vicinity of the fixed portion of the base plate 60. Further, the upper vehicle body 3 is rotated with respect to the lower vehicle body 1, and the boom cylinder 6 b and the attack angle setting cylinder 9 are expanded and contracted, whereby the guide rail 12 is positioned above the base plate 60.
Then, while the telescopic rod 33 of the swing cylinder 32 of the swing mechanism 30 is expanded and contracted, the turning motor 10 is rotationally driven to change the support angle of the bar 40 by the guide rail 12. Thereby, each bar 40 can be advanced respectively in directions a and b different by 90 degrees.

Next, as shown in (3) and (4) in FIG. 9, the bar material embedding device 100 is caused to travel along the front-rear direction FR and is moved to the vicinity of the fixed portion of the base plate 60 to be constructed next. . Further, the upper vehicle body 3 is rotated with respect to the lower vehicle body 1, and the boom cylinder 6 b and the attack angle setting cylinder 9 are expanded and contracted, whereby the guide rail 12 is positioned above the base plate 60.
Then, while the telescopic rod 33 of the swing cylinder 32 of the swing mechanism 30 is expanded and contracted, the turning motor 10 is rotationally driven to change the support angle of the bar 40 by the guide rail 12. Thereby, each bar 40 is advanced toward directions c and d different from each other by 90 degrees.

In FIG. 10, four bar members 40 are inserted into one base plate 60 in four different directions a to d.
In this case, the bar embedding device 100 is run in the front-rear direction along the front-rear direction FR in the vicinity of the fixed portion of the base plate 60.
Then, the upper vehicle body 3 is rotated with respect to the lower vehicle body 1, and the boom cylinder 6 b and the attack angle setting cylinder 9 are expanded and contracted to position the guide rail 12 above the base plate 60.

  When the bar 40 is advanced in each of the four different directions a to d, the turning motor 10 is rotationally driven while the telescopic rod 33 of the swinging cylinder 32 of the swing mechanism 30 is expanded and contracted, so that the bar 40 by the guide rail 12 is driven. Change the support angle. Thereby, each bar 40 can be advanced in the directions a to d different by 90 degrees and inserted into the ground.

  As described above, in the bar material embedding device 100 according to this embodiment, in addition to traveling and adjusting the position of the guide rail 12 by the boom 6 or the like, the ground motor GL of the guide rail 12 is driven by rotating the turning motor 10. The support angle α can be changed to a desired angle. For this reason, the support angle α can be changed to four different directions a to d effective for fixing the base plate.

Further, the telescopic rod 33 of the swing cylinder 32 of the swing mechanism 30 can be expanded and contracted to tilt the guide rail 12 within the range shown between the solid line position and the two-dot chain line position in FIG.
Then, the slide rod 22 is expanded and contracted and moved back and forth in the longitudinal direction of the guide rail 12. Thereby, the front-end | tip guide part 12a can be adjoined or separated from the ground surface GL, and the space | interval suitable for insertion of the bar 40 can be obtained.

  In the pipe insertion machine 11 of this embodiment, the angle of the guide rail 12 is changed for each bar 40, and the bar is under substantially the same conditions (angle, interval, insertion force) in different directions a, c, b, and d. 40 can be inserted. For this reason, even if a plurality of through-holes 64 in different axial directions L are formed in one base plate 60, the traveling movements (1) to (4) of the bar material embedding device 100 are kept linear and to the minimum distance. (See FIG. 10).

  At this time, as shown in FIG. 15, the base plate 60 is fixed in the fixing means 74 by the fixing tool 80. The frame portion 76 constituting the fixing means 74 is connected to the long positioning member 72 of the base plate installation jig 70. For this reason, even if force is applied to the base plate 60 when the bar 40 is inserted by the bar embedding device 100, there is no possibility that the position of the base plate 60 is shifted.

  When the bar 40 is inserted from the ground surface GL into the ground and reaches a desired embedding position, a bolt member (not shown) is inserted into a bolt hole 64b (see FIG. 5) formed in the peripheral wall of the guide tube portion 64a. Is inserted. By screwing the bolt member, the tip of the bolt member is brought into contact with or engaged with the side surface of the bar 40. Thereby, the bar 40 is fixed to the base plate 60 so as not to move in the axial direction L.

  17 and 18 show a state in which the bar 40 is inserted from four different directions toward the ground. In this state, the four bar members 40 are inserted obliquely in different circumferential directions by 90 degrees. For this reason, the base plate 60 is stably fixed to the ground surface GL against an external force in any direction.

Further, in this embodiment, the base plate installation jig 70 is used for the installation of installing the base plate 60. Thereby, the plurality of base plates 60 are regularly arranged at predetermined intervals in the arrangement direction W and the width direction X, respectively, as shown in FIG.
For this reason, connection with the mount frame etc. of the solar panel (not shown) mounted above the base plate 60 can be performed easily.

Further, the bars 40 of the base plates 60 arranged adjacent to each other are embedded in four directions at positions rotated 45 degrees about the vertical axis 61 with respect to the arrangement direction W and the width direction X, respectively.
For example, when the axial direction is the same direction, and the direction in which the external force is applied and the longitudinal direction all match, each bar 40 is easy to come off, and the solar panel pedestal or the like placed above is overturned. There is a risk of causing it.
In particular, the gantry may have a square shape in a top view according to the shape of the solar panel. In such a case, the external force in the same removal direction in the arrangement direction W or the width direction X is applied to the base plates 60 arranged close to each other to support the same frame, and the bar 40 may be pulled out at the same time.
On the other hand, in the base plate installation jig 70 of this embodiment, the arrangement direction W or the width direction X and the insertion direction of each bar 40 are shifted by 45 degrees. For this reason, the force applied to the base plate 60 from the same base is unlikely to coincide with the direction in which the bar 40 is pulled out, and the bar 40 is not easily pulled out from the ground surface GL.
For this reason, compared with the case where the bar 40 is inserted in the ground in the same direction as the arrangement direction W or the width direction X, the construction stability is better.

  Further, after the base plate 60 is fixed, the base plate installation jig 70 can be removed, and the base plate installation jig 70 can be moved and reused. For this reason, the increase in construction cost is further suppressed.

In a state where the base plate 60 is fixed to the ground surface GL, a structure such as a solar panel gantry is placed above the base plate 60 as a base. In this foundation construction method, for example, the base plate 60 can be easily fixed to the ground surface GL by inserting the bar 40 into the ground as compared with the case where the base plate 60 is fixed to the ground surface GL with mortar.
Moreover, no time is needed to cure the mortar. For this reason, construction workability | operativity is favorable and the convenience of the whole construction can be improved.

  The present invention is not limited to the above-described embodiments, and various modifications are possible. The above-described embodiments are illustrated for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. Further, a part of the configuration of an embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of an embodiment. Further, it is possible to delete a part of the configuration of each embodiment, or to add or replace another configuration. Possible modifications to the above embodiment are as follows, for example.

  In this embodiment, the positioning member 72 includes a pair of left and right ladder frames 72a and 72a extending along the arrangement direction W of the base plate 60, and a predetermined interval between the ladder frames 72a and 72a. It has connecting members 72b and 72b. However, the present invention is not limited to this, and any number may be used as long as a plurality of fixing means 74 can be attached, such as using one or three or more frame materials, and the number and shape of the frame materials are not limited. .

  Further, in this embodiment, the base plate 60 is shown and described as being inserted and fixed with the four bar members 40, but is not limited thereto. For example, the number of bars 40 and the insertion angle are not particularly limited as long as the bar 40 can be fixed to the ground surface GL using one or two or more bars 40.

  Furthermore, the shape of the bar 40 is not a pipe shape such as a cylindrical shape or a rectangular tube shape, but may be a solid rod body or may not be made of metal. Further, the length dimension of the bar 40 is not limited to the length of the embodiment. For example, as long as a desired fixing strength can be obtained, the shape may be short, and the cross-sectional shape, dimensions, and material are not particularly limited.

  Moreover, in the bar | burr material embedment apparatus 100 of this embodiment, although the thing using an endless track was shown and demonstrated as the traveling body 2, it is not restricted to this especially, Other forms, such as a wheel and a leg-shaped walking body, are shown. A traveling body may be sufficient. Furthermore, it is not restricted to what can be self-propelled with a power source. For example, a trailer type towed by a towing vehicle may be used.

  Further, the base plate 60 may be fixed by inserting the bar 40 toward the ground using a handy type insertion machine or a hammer without using the bar embedding device 100. That is, any device and tool may be used as long as the base plate 60 positioned and installed can be fixed to the ground surface GL by inserting a member such as the bar 40.
