Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for cleaning a rock surface, and more particularly to a technique devised so that it can be cleaned by using an existing powered excavator having an excavating bucket such as a backhoe. It is.

[0002]

2. Description of the Related Art For example, in the construction of a dam, it is usually necessary to clean a rock surface or a surrounding rock surface which is a foundation of the dam body before constructing the dam body. Cleaning the rock surface involves performing various tasks such as securing the bond strength between the rock and concrete or between the rock and the contact clay, checking for cracks in the rock, applying filler material when cracks are present, and leveling the rock surface. This is because it is needed above.

[0003] Such a work of cleaning the rock surface is generally performed manually by many workers. At that time, a so-called air cleaning method of blowing compressed air is also used as needed.

[0004]

However, such a conventional rock cleaning method requires labor and time, resulting in a problem that the construction period is lengthened and the construction cost is increased. In particular, since the work area for cleaning the rock surface in the construction of dams is wide, some countermeasures are required. As a solution to this point, it is conceivable to separately manufacture a dedicated powered machine for cleaning and use this.However, in addition to the conventionally required civil engineering machines such as backhoes, new Due to the cost of civil engineering equipment, this is not a very good solution.

The present invention has been made in view of the above points, and focuses on the existence of an existing powered excavator such as a backhoe used for excavation of rock or earth and sand. It is an object of the present invention to provide a technology that can improve the efficiency of cleaning work by making it possible to effectively use the cleaning work, and that the production cost for the cleaning work can be extremely low.

[0006]

According to the present invention, there is provided an apparatus for cleaning a rock surface, comprising: a power-driven excavator having a bucket for digging; And a lock brush for sweeping a rock surface with a brush portion on a tip side thereof. Here, when there is a claw for excavation at the tip of the bucket, a lock brush can be detachably attached to the claw. On the other hand, the present invention provides a cleaning method including the steps of: cleaning a rock surface using a power of a power-driven excavator having a bucket for excavation; and an air cleaning step. A rock brush for sweeping the rock surface is attached to the part, and the air cleaning process is performed while moving the rock brush on the rock surface by the power of the excavator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to FIGS. FIG.
FIG. 2 is a perspective view showing a state in which the rock surface is cleaned using the rock cleaning device according to the present invention, FIG. 2 is an enlarged perspective view showing a main part thereof, and FIG. It is a perspective view.

As can be understood from these drawings, the rock cleaning apparatus according to the present embodiment includes
A backhoe widely known as a hydraulic excavator is used. The excavator K composed of this backhoe has an arm 1
The bucket B is provided with a swingable bucket B provided at the tip of the rocker, and a rock or the like can be excavated while performing an operation of pulling the bucket B toward the near side.

At the tip of the bucket B of the excavator K, there is a claw 2 for excavation, and a lock brush 10 for sweeping the surface of the rock G is detachably attached to the claw 2. In the illustrated example, five pawls 2 are provided in one horizontal row, and a lock brush 10 is attached to each pawl 2.

The lock brush 10 has improved teeth (tooth) mounted on the claw 2, and has an attachment portion 11 for the claw 2 and a brush portion 12 as shown in FIGS. 2 and 3. The brush portion 12 is, for example, a bundle of a large number of piano wires, and is designed to have elasticity and sufficient toughness required for cleaning the surface of the bedrock G. Of course, the present invention is not limited to the piano wire, and may be made of a linear material having another similar function.

An insertion hole 11a and a bolt hole 11b are provided in the mounting portion 11 of the lock brush 10 for stably mounting and fixing the lock brush 10 to the claw 2. One of the claws 2 has a bolt hole 2b. Is provided. Then, as shown in FIG. 2, with the lock brush 10 attached to the claw 2, it is firmly fixed with bolts 14 and nuts 15, whereby the lock brush 10 is detachably attached to the claw 2. Of course, the attachment of the lock brush may use another existing method.

When the cleaning operation is performed using the rock cleaning apparatus having such a configuration, as shown in FIG. 1, the caterpillar C of the backhoe (excavator) K moves to the place to be cleaned, and the bucket is moved. Operate B to lock brush 10
It is sufficient to sequentially clean the surface of the bedrock G while sweeping the surface of the bedrock G with the brush portion 12. At this time, it is preferable to perform the cleaning together with an air cleaning operation method in which compressed air is discharged from the tip of the air injection nozzle 20. By doing so, relatively large rocks, crushed stones, earth and sand souls, etc. can be swept with the lock brush 10 and the particles having a small particle size can be cleaned by blowing them off with compressed air.

Such an operation can be performed very easily by moving the backhoe K to an arbitrary position using the caterpillar C and swinging the bucket B. Therefore, it can be performed efficiently without relying only on human power.

Further, since a backhoe normally used at the site of dam construction is used for the power-driven mechanical portion, there is no need to separately manufacture or prepare a high-cost power portion. Further, since the lock brush 10 is configured to use the claw 2 in the bucket B as it is for attachment, the production cost can be extremely low. In addition, since the lock brush 10 is detachable, if the lock brush 10 is removed, the backhoe K returns to the form in which the original function can be exhibited.

The bolt holes 11b provided in the mounting portion 11 of the lock brush 10 are vertically elongated holes, so that the bolts 14 and the nuts 15 can be easily attached and detached. Generally, the portion of the claw 2 of the bucket B may be damaged by repeated work of excavation or the mud may be strongly adhered.
It is expected that it will be difficult to attach the bolts exactly, but it is very effective to form the bolt holes 11b as long holes.

In the embodiment, an example is shown in which a backhoe is used for the power portion of the cleaning device. However, any power machine having a similar function can be applied.
Further, although the case where the object to be cleaned is the rock surface of the dam has been described, it is needless to say that the present invention can be applied to other similar objects to be cleaned.

[0017]

As described above, in the rock cleaning apparatus according to the present invention, a power type excavator having a bucket for excavation, a detachable attachment to the tip of the bucket, and a brush portion on the tip side. Because it is configured to include a rock brush for sweeping the rock surface, it is possible to effectively use an existing powered excavator such as a backhoe used for excavating rock and earth and sand as a powered cleaner. As a result, the cleaning work can be made more efficient, and the production cost for that can be extremely low.

Further, when the bucket has an excavating claw at the tip portion, the lock brush is detachably attached to the claw, so that the bucket can be constructed without any processing. it can. Therefore, not only the manufacture of the lock brush is sufficient, but also a function as a cleaning device can be added to the excavator in addition to its original function.

In the cleaning method of the present invention, when cleaning the rock surface, a rock brush for sweeping the rock surface is attached to the tip of the bucket of the excavator, and the rock brush is mounted on the rock surface by the power of the excavator. The cleaning efficiency can be further improved by performing the air cleaning process while moving the cleaning device, and the entire cleaning process can be performed mechanically.
