Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a compaction finishing device used in civil engineering work.

(Prior Art) In civil engineering work, it is often necessary to compact the earthwork glue surface. Examples include shaping and compacting the surface of a road construction embankment, shaping and finishing a floor surface for installing concrete block frames, and shaping and compacting colomo soil when installing striated turf on the embankment surface.

Conventionally, a mechanical construction method has been known for shaping and compacting clayey soil by pressing it with a nori surface bucket attached to a backhoe. However, this mechanical construction method cannot be applied to sandy or silty soils because it is impossible to compact them even by pressing the paste surface bucket, so manual construction using doba-kari is relied on.

(Problems to be Solved by the Invention) In the conventional glue surface compaction method, mechanical construction methods cannot be applied to the glue surface of sandy soil or silty soil, and the method is limited to manual construction using clay panels. For this reason, a great deal of effort and time is spent on the work, which, combined with the recent labor shortage, has become a serious problem.

(Means for Solving the Problems) The compaction finishing device of the present invention comprises: a backhoe; a bucket held at the tip of an arm of the backhoe; A vibrating compaction machine is provided at the tip of the arm, facing the top plate of the bucket, so as to be rotatable back and forth and to the left and right, and to be translatable up and down via parallel links.

Hereinafter, the operation of the present invention will be explained in detail together with examples.

(Example) Fig. 1 is a side view showing the overall configuration of a compaction finishing device according to an embodiment of the present invention, Fig. 2 is a front view of a vibrating compaction machine and a bucket located behind it, and Fig. The figure is a sectional view taken along the line AA' in FIG.

For convenience of explanation, orthogonal coordinates (X.

Y, Z) are set.

1 to 3, 1 is a backhoe, 2 is a mounting tool, 3 is a bucket device, and 4 is a vibratory compaction unit consisting of a vibratory compaction machine and its holding mechanism.

As the backhoe 1, a general-purpose commercial product is used as is.

This backhoe 1 includes a main body part 1a which is equipped with a remote control mechanism for each part of the compaction finishing apparatus and which can move forward and backward, and a bendable arm part 1b which projects forward of the main body part 1a. A bucket device 3 and a vibrating compaction section 4 are attached to the tip of the arm section 1b of the backhoe via a mounting tool 2.

The bucket device 3 includes a main body portion 3a for scooping up earth and sand, and a top plate 3b that can be opened and closed when supplying the scooped earth and sand to the vibration compaction machine 4.

The main body part 3a of the bucket is composed of a bottom plate and both side plates,
It preferably has a triangular shape. The top plate 3b corresponds to that of a general-purpose bucket with a top plate, and a pin mounting stand 3C is fixed to the front left and right ends, and a pin mounting stand 3e is fixed to the front center part. The pin mounting bases 3C fixed to the left and right ends of the top plate 3b are for mounting the bin 3d and the hydraulic cylinder 3f. A hydraulic cylinder 3f opens and closes the space between the bucket body 3a and the top plate 3b centering on the bin 3d.

The pin mounting base 3e has a pin 3h and fan-shaped internal teeth (3) (4). Hydraulic cylinders 3f are arranged on both sides of the top plate 3b for opening and closing the main body 3a of the bucket and the top plate 3b. H-type frame 3g and H-type frame 4e
are connected to each other so as to be rotatable parallel to each other and laterally (within the XY plane) via a torque actuator 4h. The lower end of one H-shaped frame 3g is rotatably attached to a stand 3e via a pin 3h, and a small gear 3j rotated by a hydraulic motor 31 with a reducer is attached to its upper end. It is being This pinion 3j is meshed with the sector-shaped internal gear 3, and when the pinion 3j is rotated by the hydraulic motor 3i with a reducer, the H-shaped frame 3g moves back and forth (Y-Z plane) around the bin 3h. within) rotate.

The vibration compaction unit 4 includes a vibration compaction machine consisting of a matrix compaction plate 4a and an exciter 4b, a pin mounting table 3e, an H-shaped frame 3g, 4e, four parallel links 4f, and an L-shaped frame. 4d and a bottle connecting these to each other, the vibrating compaction machine is attached to the tool 2 by a holding mechanism that holds it rotatably in the front, rear, left and right directions and translatable up and down. This vibrating compaction section performs compaction by vibrating the boat-shaped rolling compaction plate 4a with a vibrator 4b while leveling the soil supplied from the bucket device 3 with a scraper. The vibration compaction machine can be rotated left and right (around the Z-axis) over a predetermined angular range by a torque actuator 4h attached to the front center of the frames 3g and 48 that constitute the H-shaped frame.

The vibratory compaction machine is mounted so that it can be translated up and down by a parallel linkage mechanism. The boat-shaped rolling plate 4a is elastically supported by an L-shaped frame 4d with four vibration-proof rubbers 4C interposed therebetween, and is caused to vibrate up and down by a vibrator 4b fixed to the central lower part of the matrix rolling plate 4a. It will be done. The vibrator 4b is fixed to the bottom plate of the boat-shaped rolling plate 4a, and generates vibration force by a hydraulic motor driven by hydraulic power supplied from the backhoe 1.

(5) (6) The L-shaped frame 4d has an L-shaped side shape, a gate-shaped rigid frame structure in front, and its lower part is fixed to the bottom plate, and supports the boat-shaped rolling plate 4a via vibration-proof rubber 4c at the four corners of the lower part. At the same time, parallel links 4f are attached at four locations on the top and bottom by pins 4g on both the left and right sides. One of the frames 4e constituting the frame is H-shaped in front, has pin holes on both left and right sides for attaching parallel links 4f, and has a pin mounting stand fixed to it, and a torque actuator in the center of the front. Eta 4h is installed. Since the bearing of the H-shaped frame 3g is press-fitted into the shaft end of the torque actuator 4h, the 11-shaped frame 4e and the H-shaped frame 3g are rotatable in the left and right directions.

The parallel link 4f, the L-shaped frame 4d, and the IJ-shaped frame 4e are rotatably connected via a pin 4g. L
The shaped frame 4d vertically translates with respect to the frame 4e via a total of four parallel links 4f arranged vertically and horizontally. The stoppers 41 are fixed to pin mounts at the left and right ends of the H-shaped frame 4e, and are used to limit the range of inclination of the parallel link 4f, and therefore the range of vertical translation of the boat-shaped rolling plate 4a.

Figures 4 (A) and (B) show the bucket main body 3a and the top plate 3.
The pin is attached to the stand 3 by the hydraulic cylinder 3f between the
It shows how the opening/closing operation is performed centering on the pin 3d of c.

Figures 5 (A) and (B) show a hydraulic motor 31 with a reducer.
As the pinion 3j rotates, the pinion 3j moves along the direction in which the fan-shaped internal gear 3 extends, causing the frame 3g to rotate back and forth (around the X axis) around the pin 3h. It shows how to do it.

6(A) and (B) show that even if the tool 2 and the bucket device 3 move upward, the L-shaped frame 4d is connected to the parallel link 4f and the pin 4g until it is stopped by the stopper 41.
This figure shows how the boat-shaped compacting plate 4a of the vibratory compaction machine and the glue surface are kept in close contact by being inclined with respect to the link 3g via the link 3g.

(7) (8) The scraper 4j is attached to the end surface of the L-shaped frame 4d on the bucket side so as to be adjustable in the vertical direction, and is capable of adjusting the amount of compacted earth and sand supplied from the bucket device 3 and uniformly distributing it. This is for supplying it to the vibrating compaction surface while smoothing it.

Although the compaction finishing device of the present invention has been described above, taking as an example the case where the target is a glued surface, the scope of application of the compaction finishing device of the present invention is not limited to only a glued surface. In other words, by using a backhoe as a self-propelled mechanism and a bucket device as a compaction soil supply mechanism, a small-capacity plate, which is currently being constructed by workers while driving on foot, can be used for vibratory compaction of horizontal roadbeds. The compaction finishing device of the present invention can be utilized as an alternative to a compactor.

(Effects of the Invention) As explained in detail above, the compaction finishing device of the present invention has a configuration in which the bucket device and the vibrating compaction machine are integrally attached to the tip of the arm of the backhoe. It becomes possible to excavate and compact the surface.

In addition, the compaction finishing device of the present invention adopts a compaction method using vibration, so it can be applied to the surface of any soil type, such as clay soil, sandy soil, silty soil, etc., using a completely mechanical method. This makes it possible to significantly reduce work effort and time.

Furthermore, since the compaction finishing device of the present invention uses a bucket device whose top plate can be opened and closed, the amount of soil to be compacted can be adjusted and supplied to the finished surface.
Work efficiency is greatly improved and a good finish is possible.

In addition, the compaction finishing device of the present invention has a structure in which the vibrating compaction machine is held at the tip of the arm so that it can rotate back and forth, left and right, and can translate up and down via a parallel link. This makes it possible to bring the material into close contact with surfaces to be finished, such as surfaces, which greatly improves compaction efficiency and provides a good finish.
