FIG. DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, an embodiment of a moving and installing device for a full-circle rotary excavator 1 according to the present invention will be described with reference to the drawings.

[0017] As shown in Figures 1 to 5, the full-circle rotary excavator 1 comprises a horizontally positioned base plate 2 that is placed on the ground and has a casing insertion hole, and an excavator main body 3 that grips the excavation casing and applies rotational and vertical forces to the excavation casing to press it into the ground, and the excavator main body 3 is mounted so that it can be raised and lowered relative to the base plate 2 by a lifting drive device 4 that has a hydraulic cylinder 4a.

[0018] The excavator main body 3 comprises an elevator drive device 4 erected on a base plate 2 and equipped with a plurality of hydraulic cylinders 4a; an elevator frame 5 located above the base plate 2 and supported in a horizontal position by the plurality of hydraulic cylinders 4a of the elevator drive device 4, and raised and lowered by the elevator drive device 4; a rotating frame 6 rotatably supported on the elevator frame 5; a main chuck device 7 provided on the rotating frame 6 and consisting of a plurality of clamping claws and clamping cylinders for gripping the excavation casing; and a rotation drive device 8 provided on the elevator frame 5 and consisting of a plurality of hydraulic motors and gear reduction devices for rotating the rotating frame 6.

[0019] The mobile installation device of the present invention, which moves and installs the full-circle rotary excavator 1 to the excavation position at the work site, comprises a frame-type cart 10 having a pair of left and right side frames 11 with self-propelled wheels 12 at their lower ends, and a plurality of frame members 13 spanning between the left and right side frames 11, as shown in Figures 6 to 8.

[0020] As shown in FIG. 9, the frame type truck 10 is formed to a size that allows the full-circle rotary excavator 1 to be housed within the space surrounded by the left and right side frames 11 and the frame member 13.

[0021] In the illustrated embodiment, the self-propelled wheels 12 use crawlers, but are not limited to crawlers and may be tires.

[0022] As shown in Figures 7 and 8, the frame member 13 in the illustrated embodiment consists of four members, from front to rear: a gate frame 13a, two central suspension frames 13b and 13c, and a rear back frame 13d.

[0023] As shown in FIGS. 10 and 11, extension frames 14 are detachably attached to the left and right ends of the four frame members 13.

[0024] The left and right side frames 11 are attached to the frame member 13 so as to be slidable in the left-right direction.

[0025] Of the four frame members 13, the front gate frame 13a and the rear back frame 13d are equipped with widening cylinders 15 that push the left and right side frames 11 outward and pull the spread left and right side frames 11 toward the center.

[0026] Furthermore, left and right adjustment cylinders 16 are installed between the left and right side frames 11 in front and behind the two central hanging frames 13b and 13c.

[0027] By extending and retracting the widening cylinder 15 and the left and right adjustment cylinder 16, the spacing between the left and right side frames 11 can be changed between a narrow spacing located at both ends of the frame member 13 shown in Figures 10 and 11, and a wide spacing located at the ends of the extension frame 14 shown in Figure 12.

[0028] As shown in Figure 13, by narrowing the distance between the left and right side frames 11 to the distance at both ends of the frame member 13 from which the extension frame 14 has been removed, the width of the frame-type trolley 10 can be made large enough to be loaded onto a truck.

[0029] By using the widening cylinder 15 and the left / right adjustment cylinder 16 to push the left and right side frames 11 out to the ends of the extension frames 14 attached to both ends of the four frame members 13, the width distance between the left and right side frames 11 can be made wider than the width of the full-circle rotary excavator 1, as shown in Figure 9.

[0030] 7, the left and right side frames 11 include a lower frame 11a on which the self-propelled wheels 12 are mounted, a pair of front and rear vertical frames 11b, 11c erected on the lower frame 11a, an upper frame 11d provided at the upper ends of the pair of vertical frames 11b, 11c, and a front vertical frame 11e provided at the front ends of the upper frame 11d and the lower frame 11a, and a gate frame 13a is attached to the front vertical frame 11e via a slide member 11f so that it can be raised and lowered relative to the front vertical frame 11e. A lifting cylinder 17 is installed on the front vertical frame 11e to raise and lower the gate frame 13a relative to the front vertical frame 11e.

[0031] Figure 6 shows the state in which the gate frame 13a has been raised upward by the lifting cylinder 17. By raising the gate frame 13a, as shown in Figure 9, the gate frame 13a can be made higher than the overall height of the 360° rotation excavator 1, and the 360° rotation excavator 1 can be accommodated in the internal space of the frame cart 10 from the front side of the frame cart 10.

[0032] On the other hand, the left and right side frames 11 are pushed apart by the widening cylinders 15 and the left and right adjustment cylinders 16 to both ends of the extension frame 14 attached to the frame member 13, as shown in Figure 12, and when narrowing the left and right side frames 11 to the end positions of the frame member 13 from which the extension frame 14 has been removed, as shown in Figure 11, the gate frame 13a is lowered by the lifting cylinders 17, and the spacing between the left and right side frames 11 is changed.

[0033] Of the four frame members 13, the two central hanging frames 13b and 13c in the front-to-rear direction are installed on the upper surface of the upper frame 11d, and the rear frame 13d at the rear end is installed at the rear end of the lower frame 11a.

[0034] In addition, above the two central hanging frames 13b and 13c, as shown by dashed lines in Figures 6 and 7, a control unit 19 equipped with a hydraulic source for driving the widening cylinder 15, left / right adjustment cylinder 16, lifting cylinder 17, etc. is installed.

[0035] As shown in Figures 14 and 15, the hanging frames 13b, 13c are provided with hanging fittings 20 that are connected to the hanging rings 9 provided on the top surface of the excavator body 3 of the 360° rotary excavator 1 when the 360° rotary excavator 1 is suspended by the frame-type cart 10.

[0036] The transport and installation device according to the present invention has the above-described configuration, and can transport and install the 360° rotation excavator 1 to the excavation position at the work site without using a crane, as follows.

[0037] First, the full-circle rotary excavator 1 and the frame type cart 10 are transported by truck to the vicinity of the excavation position at the work site.

[0038] When transporting the frame-type trolley 10 by truck, as shown in Figure 13, the extension frames 14 at both the left and right ends of the four frame members 13 are removed, and the width gap between the left and right side frames 11 is narrowed by the widening cylinders 15 and the left and right adjustment cylinders 16.

[0039] Then, the frame type cart 10 is transported by truck to near the excavation position at the work site, and as shown in Figure 11, extension frames 14 are attached to both left and right ends of the four frame members 13 of the frame type cart 10 that has been lowered from the truck bed, and then the spacing between the left and right side frames 11 is widened using the widening cylinder 15 and left and right adjustment cylinder 16 to the ends of the extension frames 14 attached to both ends of the four frame members 13, as shown in Figure 12.

[0040] Next, as shown in Figure 6, the gate frame 13a is raised upward by the lifting cylinder 17, and in this state, the self-propelled wheels 12 of the frame type cart 10 are driven to move the frame type cart 10 so that the full-circle rotating excavator 1 can enter between the left and right side frames 11 from the front of the frame type cart 10, as shown in Figure 9.

[0041] After this, as shown in Figure 14, the hydraulic power source of the control unit 19 of the frame type cart 10 is connected to the 360° rotation excavator 1, and the hydraulic power source of the frame type cart 10 is used to drive the lifting drive device 4 of the 360° rotation excavator 1, thereby raising the excavator body 3 relative to the base plate 2 and connecting the lifting ring 9 provided on the top surface of the excavator body 3 to the lifting fittings 20 of the hanging frames 13b, 13c of the frame type cart 10.

[0042] After this, when the base plate 2 is pulled up by the lifting drive device 4 of the 360° rotary excavator 1, the 360° rotary excavator 1 is lifted off the ground and is suspended from the frame-type cart 10, as shown in Figure 15.

[0043] In this state, the self-propelled wheels 12 of the frame type carriage 10 are driven, and the full-circle rotary excavator 1 is moved to an excavation position at the work site while being hoisted by the frame type carriage 10.

[0044] In this way, the 360° rotary excavator 1 is moved to the excavation position at the work site by the frame type cart 10, and then the hydraulic power source of the frame type vehicle 10 is connected to the hydraulic power source of the 360° rotary excavator 1, and the base plate 2 is lowered using the lifting drive device 4 of the 360° rotary excavator 1 while aligning it with the excavation position at the work site.After the base plate 2 is placed on the ground, the connection between the lifting ring 9 of the 360° rotary excavator 1 and the lifting fitting 20 of the frame type cart 10 is released.

[0045] After the full-circle rotary excavator 1 has been installed at the excavation position at the work site in this way, the frame type carriage 10 is moved and the full-circle rotary excavator 1 starts excavation work.

[0046] As described above, according to the transport and installation device of the present invention, the 360° rotation excavator 1 can be moved by the frame-type cart 10 without using a crane, and the 360° rotation excavator 1 can be installed at the excavation position at the work site.

[0047] Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the illustrated embodiments. Various modifications and variations can be made to the illustrated embodiments within the same scope as the present invention or within an equivalent scope. [Explanation of symbols]
