Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled vibration compaction device used for backfilling excavated ground and the like, and more particularly, to a self-propelled vibration compaction device capable of compacting cleanly and efficiently along the boundary of excavated ground. The present invention relates to a traveling vibration compaction device.

[0002]

BACKGROUND OF THE INVENTION Electricity,
Gas and water lines and pipes are usually buried under paved roads, so repairing them requires excavating the paved roads in certain sections. In such a construction site, the pavement surface is cut first, the soil in the construction section is excavated with a shovel car, the soil is backfilled after repairing the specified line or pipe, and the pavement work is performed after compacting the soil. Do. Both manual and self-propelled devices are widely used for compaction of backfilled soil.

As a manual compacting device, for example, Japanese Patent Application Laid-Open
5-287706, 6-173215, 6-93011, 6-212605
Nos. 7-18652, 6-93039, and 7-113209 propose various structures. Further, as a self-propelled compacting device, Japanese Patent Application Laid-Open No. 4-31603 is known.
The self-propelled compacting device disclosed in Japanese Patent Application Laid-Open No. Hei 4-312603 is composed of a small caterpillar wheel that is operated by a handle like a lawn mower, and the lower end of a hammer rod fixed to an arm in front of the caterpillar vehicle A vibration plate member is swingably attached to the vibration plate member. The vibrating plate member has a general shape in which the front is curved in an arc shape like a sled plate or a ship bottom.

However, it has been found that a vibration plate member having a general shape in which a forward portion is curved in an arc shape like a sled plate or a ship bottom has various problems whether it is a manual type or a self-propelled type. For example, when cutting the pavement surface almost linearly with a cutter as in the construction of electricity, gas, water supply, etc.,
Compaction of the backfilled soil must be performed without any gaps at the boundaries of the excavation area, but it is difficult to efficiently compact the soil without damaging the pavement surface of the self-propelled type. For this reason, the compaction in the boundary region has to be performed slowly by a manual vibration compaction device, and there is a limit in improving the work efficiency.

When compacting grounds of various sizes, it is desirable to use differently sized vibrating plate members, but the vibrating plate members are not detachable in the conventional compacting apparatus. Was. For this reason, the efficiency is poor because a large area is compacted with a small vibrating plate member, or the boundary of a pavement surface is often damaged because a small area is compacted with a large vibrating plate member.

Accordingly, it is an object of the present invention to provide a self-propelled vibration compaction device capable of compacting efficiently even in areas of various sizes.

[0007]

In view of the above object, as a result of intensive studies, the present inventor has formed a vibrating plate member into a box shape having an open rear end, and oscillated with respect to a vibration transmitting shaft member. It was discovered that by making it free, compaction of the boundary of the excavation area can be performed cleanly and efficiently,
The present invention has been made.

That is, the self-propelled vibration compaction device of the present invention compacts the ground by vibrating force of a flat plate member, and the plate member has a substantially flat bottom plate and a portion other than a rear end portion. A substantially vertical side member integrally provided on the side of the vehicle, and the plate member is swingable via a rotation mechanism to a vibration transmitting shaft member attached to the arm of the self-propelled vehicle. It is characterized by being attached.

[0009]

FIG. 1 shows an example of the self-propelled vibration compaction device of the present invention, and FIGS. 2 and 3 show cross sections in the front-rear direction, respectively. FIG. 4 is a view showing the whole of a self-propelled vibration compaction device attached to a self-propelled vehicle.

The vibration compaction apparatus 1 of the present invention is mounted on an arm 12 of a self-propelled vehicle 10 via a mounting 2. The self-propelled vibration compaction device 1 includes a flat plate member 4 that presses the ground while vibrating, a vibration transmitting shaft member 7 swingably connected to the plate member 4, and a vibration transmitting shaft member 7. And a vibration force applying device 8 attached to the attachment 2 of the arm portion 12 for applying a force.

The plate member 4 comprises a substantially flat rectangular bottom plate 41 and substantially vertical side members 42a, 42b and 42c integrally provided on the sides other than the rear end. It has a box-like shape. Three sides of the bottom plate 41 are side members 42a,
Since the plate member 4 is surrounded by 42b and 42c, the plate member 4 has a large resistance to deformation when pressed. While soil and gravel enter the plate member 4 while compacting the ground while vibrating, no side member is provided at the rear end of the bottom plate 41 in order to easily remove them. As shown in FIG. 3, when the plate member 4 is vibrated while being lifted, the plate member 4 swings.
Dirt and gravel inside is easily removed.

A pair of projections 43a, 43b are provided on the upper surface of the bottom plate 41.
Has been fixed. As shown in FIG.
It is preferable that the arrangement directions of a and 43b are perpendicular to the traveling direction D of the plate member 4, but may be the same as the traveling direction D. Openings 44a, 44b are provided at the center of each of the projections 43a, 43b, and the shaft member 5 is fitted into the openings 44a, 44b. A fastener 52 is fixed to one end of the shaft member 5, and a detachable fastener (not shown) is attached to the other end.
Are locked by pins or the like, so that the shaft member 5 does not fall off the pair of projections 43a and 43b. In order to take out the shaft member 5 from the pair of protrusions 43a and 43b, a notch 45 is provided in at least one of the side members 42b and 42c.

A cylindrical member 6 surrounding the shaft member 5 is provided between the pair of projections 43a and 43b. The lower end of the vibration transmitting shaft member 7 is fixed to the center of the cylindrical member 6 by welding or the like. I have. The cylindrical member 6 is rotatable with respect to the shaft member 5, and both constitute a rotation mechanism. Because of this rotation mechanism, the plate member 4 is swingable with respect to the vibration transmitting shaft member 7.

Since the upper end of the vibration transmitting shaft member 7 is engaged with the vibration applying device 8, the shaft member 6 transmits the vibration to the plate member 4. The vibration force applying device 8 may be the same as a known device used for a hydraulic breaker or the like. Therefore, the detailed description is omitted here. The vibration force imparting device 8 is detachably mounted on the fixture 2 by a plurality of bolts 2a.
The fixture 2 is also removably attached to the arm 12.

The vibration transmitting shaft member 7 is detachable from the vibration force applying device 8 by a known mechanism. Therefore, by exchanging the set of the plate member 4 and the vibration transmitting shaft member 7, it is possible to cope with excavation areas of various sizes. The same can be performed by removing the plate member 4 from the shaft member 5. In any case, since the plate member 4 is detachable, if various sizes are prepared in advance, it is possible to cope with compaction regions of any size.

FIG. 5 shows an example of compaction work using the self-propelled vibration compaction apparatus 1 of the present invention. This is an example in which a hole 50 excavated in a slender rectangular shape for repair work of a line or a pipe for electricity, gas, water or the like is backfilled and then compacted. At the central portion of the hole 50 (a portion far from the periphery of the hole), the plate member 4 is advanced while applying vibration to the plate member 4 in the same manner as in the normal compaction work. Since the plate member 4 is provided at the tip of the arm portion 12 of the self-propelled vehicle 10, it can move forward at a constant speed.
Therefore, not only can it be compacted without unevenness, but also the operation can be performed with extremely high efficiency. In addition, since the vertical side members 42a, 42b, and 42c are provided on the side surfaces of the rectangular plate member 4, the plate member 4 is
It is possible to move along each of 1, 52, 53, 54 without a gap.

For example, compaction of the area near the side 51 is performed by moving the plate member 4 so that the side member 42c of the plate member 4 is along the side 51. When the compaction of the area near the side 51 is completed and the plate member 4 reaches the vertex X, the plate member 4 is moved laterally. Similarly, compaction of the area near the side 52 is performed by moving the plate member 4 to the vertex Y so that the side surface member 42a of the plate member 4 is along the side 52. In this way, compaction of the area near all sides 51, 52, 53, 54 can be performed easily and efficiently. As described above, in a normal rectangular site, there is an advantage that compaction can be performed without a gap by the rectangular plate member 4 having the vertical side members.

Although the self-propelled vibration compaction device of the present invention has been described with reference to the illustrated embodiments, the present invention is not limited to these embodiments, and various modifications may be made within the scope of the technical concept of the present invention. Can be applied. For example, the bottom plate 41 of the plate member 4 is not limited to a rectangular shape, and may be another shape such as a circle. Further, the swing angle of the plate member 4 may be limited by providing an appropriate stopper on the shaft member 5. Further, instead of using a combination of the shaft member 5 and the cylindrical member 6, a cylindrical member to which the vibration transmitting shaft member 7 is fixed is positioned between the pair of protrusions 43a and 43b, and stoppers are screwed on both ends thereof. Or it may be pinned.

[0019]

As described above in detail, in the self-propelled vibration compaction device of the present invention, a plate member having a box-like shape having an open rear end is swingably attached to a vibration transmission shaft member. With such a structure, clean compaction can be efficiently performed without gaps in any excavation / backfill area. Since the self-propelled vibration compaction device of the present invention can be attached to a power shovel, a bulldozer, or the like,
There is an advantage that excavation, backfilling and compaction can be efficiently performed by one device.
