Description

[Detailed Description of the Invention] Industrial Application Field The present invention is used in road construction, land reclamation work, etc.
Regarding the vibration compaction machine installed as a tip attachment on a hydraulic excavator (excavator type), in particular, the vibration compaction machine installed as the accessory has multiple capabilities of light excavation, soil removal, and ground compaction work, and it is difficult to perform these tasks. This makes it possible to do both at the same time.

Traditionally, in road construction and land preparation work, 4-hyperactive work such as earth and sand, asphalt mixture, and backfilling work are performed using excavators such as power sigibels, while soil shaping The work is often carried out by workers using shovels, rakes, etc. In this way, when work is performed using a combination of human power and a plurality of single-function machines, a large number of earthmoving workers and machine operators are required, and there is a problem in that costs increase due to personnel expenses. In addition, it is extremely dangerous to have workers close to operating machinery, and the time involved in moving the machine for each job, as well as increased machine management and transportation costs, are factors that increase the number of construction days and the unit cost of construction. It becomes.

Furthermore, for the compaction work in the above-mentioned road and land development work, conventionally known self-propelled vibrating rollers have been used, and the self-propelled vibrating rollers have guide rollers on the rear wheels.
An eccentric vibrating roller is placed on the front wheel, and the vibrating roller is used to compact the ground while running on its own, but it is difficult to run on slopes and embankments, so compaction cannot be done easily in these areas. As shown in Fig. 1θ, it was difficult to compact the area around the structure 3. That is, as shown in FIG. 1O ([), in the vibrating roller 2, a non-rolling area X is created around the structure 3, so a rolling surface G is created in the non-rolling area X, and more earth and sand is piled up. After the extra embankment Y has been applied, it is compacted with vibrating rollers 2 so that the compaction effect extends to the edge of the structure, and then the raised portion Z is removed and shaped, which is a complicated work.

On the other hand, on slopes and embankments, as shown in Figs. 11 and 12, compaction work is carried out by suspending a vibrating roller 4 with a crane 6 via a wire 5. A hoisting device for moving the roller and heavy machinery that can withstand the load of the vibrating roller and move it laterally are required, resulting in high costs. Furthermore, uniform compaction is not possible and unevenness tends to occur, and the vibrating roller operator is exposed to dangers such as falling rocks and overturning, which poses safety problems and increases construction costs. Ta.

In addition, compaction work on slopes has conventionally been carried out using slope compaction plates; Therefore, the compaction capacity was lower than the linear pressure shown in Figure 8 (1), so strong compaction was not possible, and it was easy to collapse due to changes in wind, rain, and other conditions, which was dangerous.

The present invention was made in view of the above-mentioned conventional problems.
A vibration compaction machine is attached as an attachment to the tip of an arm attached via a boom to a shovel-type hydraulic excavator with a traveling device, making it possible to perform excavation and earth removal work at the same time as vibration compaction work. , by using an attachment with multiple functions,
Perform multiple tasks with a single machine, simplify complex tasks, shorten construction days and reduce construction costs, and reduce dangerous manual labor to ensure work safety. This is to make it possible to do so.

Structure of the Invention In order to achieve the above object, the present invention provides an attachment that is attached to the upper end of the frame as an attachment that is detachably attached to the tip of the arm, and is attached to the boom installed in a hydraulic excavator having a traveling device. A bracket is provided, and the bracket is rotatably attached to the end of the arm,
To provide a vibratory compaction machine to be attached to an excavator, characterized in that an eccentric vibrating roller is attached to the frame via vibration-proof rubber, a bucket is provided at one end of the frame, and a discharge plate is provided at the other end. It is.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be explained in detail with reference to embodiments shown in the drawings.

The excavator according to the present invention has the configuration shown in FIG.
is attached removably.

The vibration compaction machine I3 has a structure shown in FIGS. 2 to 4, and has a bracket 15 fixed to the upper surface of a frame 14 as shown, and a pair of bearings 16 in the center of the bracket 15.
16 is provided protrudingly, and pin mounting holes 17 are bored on both sides of each bearing portion 16.16. The distal end connecting portion of the arm 12 is fitted between these bearing portions 16 and 16, and is rotatably attached.

That is, the set pin 18 shown in FIG. 5 is inserted in a state in which a hole (not shown) drilled in the above-mentioned end connecting portion of the arm 12 is communicated with the above-mentioned pin attachment hole 17, and one end of the set pin 18 is inserted. While the formed stopper part 18a is locked to one of the bearing parts 16, a collar 19 is fitted onto the tip of the set pin 18 that protrudes from the other bearing part 16, and a hole 19a is formed in the collar 19 and the set pin 18. , 18b, and the lock pin 20 is prevented from coming out by an R pin 21 (this method is an example of an attachment method, and other attachment methods can be adopted as appropriate).

The frame 14 of the vibrating compaction machine I3, which is rotatably connected to the arm 12, has left and right side parts 14a, 14.
A bucket portion 2'2a having a V-shaped cross section is formed between the upper end portions of b by a bucket 22 attached adjacent to the bracket attachment portion 14c.
This makes it possible to transport earth and sand. Also, both left and right sides 1
A soil removal plate 23 is provided between the lower parts of 4a and 14b, so that soil can be removed by the soil removal plate portion 23a. As shown in FIG. 3, these buckets 22 and earth removal plates 23 are placed on the frame 1 so that they do not interfere with the vibrating roller 24 installed in the center between the left and right sides 14a and 14b.
They are arranged symmetrically at both the upper and lower ends of 4.

The structure of the vibrating roller 24 is shown in detail in FIG.
The bearing plates 27a and 27b are fixed to the central portions of both sides of the end plate 41, and the main shaft 26 is fixed to the central part of the mirror plate 41 on both sides of the bearing plates 27a.
, 27b via bearings 28a128b so as to be rotatable. One protruding end of the main shaft 26 is connected to a hydraulic motor 29, and an eccentric 30 is fixed to the main shaft 26 at a positionally shifted center inside the drum 25. Therefore, when the main shaft 26 is rotationally driven by the hydraulic motor 29, the rotational movement of the main shaft 26 is converted into an eccentric movement by the eccentric element 30, so that the drum 25 is vibrated. The drum 25 and the frame both sides 14a, 14b are connected by the above-mentioned both side bearing plates 27a127b and bearings 31a,
Connecting plates 32a, rotatably connected via 31b,
32b is fixed to one end surface of vibration isolating rubbers 33a and 33b, and the end surfaces of these vibration isolating rubbers are attached to both sides of the frame 14a and 14b.
This prevents the vibration of the drum 25 from being applied to the frame 14.

As mentioned above, the vibrating compaction machine I3 equipped with the vibrating roller 24, the bucket 22, and the earth removal plate 23 is attached to the tip of the Arno 12 connected to the boom of a hydraulic excavator with a traveling device a. Accordingly, light excavation work and earth removal work with the earth removal vi, 22, transportation work of the earth and sand with the bucket 22, and vibrating roller 24 as shown in FIG.
Ground compaction work can be done simultaneously with one machine.

In particular, in compaction work, the drum 25 of the vibrating roller 24
The rotation of the main shaft 26 by the hydraulic motor 29 causes vibrations to be applied by the eccentric element 30, and the drum 25 itself is rotatable with respect to the connecting plates 32a, 32b and the main shaft 26 via bearings, respectively. , when moved by the traveling device, it rotates as shown in FIG. 8 (1) and provides continuous vibratory compaction action to the ground G.

Therefore, the compaction of the ground G can be done uniformly and quickly. It is clear that the action of the vibrating roller 24 is efficient when compared with the plate compaction machine 40 shown in FIG. 8 (II). That is, plate compaction 44
40 requires an operation to raise it to the position shown by the dotted line and then lower it after one compaction, and the operation is intermittent, making it impossible to perform continuous compaction, which takes time and causes uneven compaction. is likely to occur.

In addition, when compacting the area around the structure shown in FIG. 1O using the vibrating compaction machine 13, the bucket 22 transports earth and sand to fill the entire area, and then the vibrating rollers 24 compact the soil, and then the soil removal plate 23 to discharge the remaining soil, and one machine can perform soil compaction work extremely efficiently.

Furthermore, the slope 50 shown in FIG. 7 can be compacted using the vibrating roller 24 with a stronger force than the conventional slope pressure plate, so there is no risk of it collapsing due to wind and rain, etc. Surface compaction work can be performed easily while maintaining safety.

This vibrating compaction machine has a set pin attached to the arm 12,
1; Because it is removably attached with a lock pin, etc.
If necessary, it can be easily replaced with the bucket 39 shown in FIG. 9 or other suitable attachments. Therefore, it is possible to transform a single excavator-type fine-cutting machine into an all-purpose machine that can be used for multiple purposes.

Effects of the Invention As is clear from the above explanation, according to the present invention, a vibrating compaction machine is attached to the tip of an arm attached to a boom installed in a hydraulic excavator having a traveling device. The vibratory compaction machine has a structure that includes a vibrating roller, a bucket, and an earth removal plate, so that compaction work, excavation, and earth removal work can be performed continuously with one machine.

In this way, multiple functions are provided in a single attachment, which simplifies multiple tasks, significantly shortening construction time, and increasing safety by reducing dangerous manual work. This makes it possible to ensure safety and reduce construction costs.
