Description

Cutting Apparatus and Construction Equipment comprising to be capable of replacing the same}

The present invention relates to a cutting device and a construction machine including the same, and more particularly, to a wheel-saw rock cutting device configured to be detachable to a drilling device and a construction machine including the same.

Excavators, which are construction machines, are widely used for civil works such as large-scale pipeline construction where water and sewage pipes, gas pipes, or communication pipes are buried in the ground, and for civil works such as arranging the ground or excavating.

These excavators have excellent maneuverability even on uneven ground, and are especially used for demolition of fork-type buckets used for excavating the ground or scooping up soil at the tip of the boom depending on working conditions, breakers for breaking rock, and concrete structures. It is widely used in various civil works because it has the advantage of being able to selectively install equipment such as a crusher.

When performing ground excavation using an excavator that can selectively use various equipment as described above, a fork-type bucket is installed at the tip of the excavator's boom and excavation is performed. When a large-sized rock mass is buried, the bucket is disassembled and a breaker is installed to remove the rock mass. The above breaker strikes the rock mass by reciprocating the striking tool with hydraulic pressure to break it.

However, when the hitting tool of the breaker strikes the rock, the hitting noise is very loud, and there is a disadvantage that a lot of dust is generated and the vibration is also severe. If a livestock house is adjacent to each other, it becomes the subject of civil complaints, and there are many difficulties in proceeding with the construction.

Therefore, in consideration of the above, instead of using a breaker, the rock is destroyed by drilling a hole in the rock by using a rock drill that can drill the rock while suppressing noise and vibration as much as possible.

[0003] In order to drill a hole in a rock or the ground, a conventional rock drilling machine is used that is configured to lift a cylindrical drilling machine that drills rock while rotating by a hydraulic motor with a hydraulic cylinder.

The rock that is cut by the perforation is removed to the outside, and the construction machine is moved to repeat the above-described perforating operation. After drilling the rock mass, a rock crusher is inserted into the hole formed in this way to crack the rock mass, that is, a halam work is performed.

However, there is a disadvantage in that the work is inefficient and the construction period is long, and even if the desired work range is set, it is not possible to accurately work up to the set range.

In the direction change member 122, the joint member 121 communicates with the upper side of the outer housing, and the first teeth 1251 communicate with the front side of the outer housing, so that the direction of the rotational force transmitted from the joint member 121 is a bevel gear. It may be configured to transfer to the first teeth 1251 after the conversion.

As another example, the direction change member 122 may be configured such that the first teeth 1251 communicate with the front side of the outer housing without a role of changing the direction, and the joint member 121 communicates with the rear side of the outer housing to be fixed. That is, the direction change member 122 may be configured such that the first teeth 1251 communicate with the front side of the outer housing without the bevel gear disposed therein, and the joint member 121 communicates with the rear side of the outer housing to be fixed. At this time, the direction change of the rotational force may be implemented by changing the configuration of the replacement device 30 to be described later.

In addition, the direction change member 122 may be formed such that a connection member 124 to be described later is fixedly connected to the lower side of the outer housing.

The power transmission member 125 may include a first tooth 1251, a second tooth 1252, and a chain 1253.

The first teeth 1251 may be formed on the direction changing member 122. The first teeth 1251 may be formed in a tooth shape, and may be rotatably formed on the direction changing member 122. The first teeth 1251 are formed to mesh with the chain 1253, and may transmit a rotational force whose direction is changed from the direction changing member 122 to the chain 1253. That is, the first teeth 1251 may supply a rotational force whose direction is changed from the direction change member 122 to the second teeth 1252 through the chain 1253.

The second teeth 1252 may be formed on the power supply member 123. The second teeth 1252 may be formed in a tooth shape and may be rotatably formed on the power supply member 123. The second teeth 1252 may be formed to mesh with the chain 1253, and may be rotated by receiving a rotational force supplied from the first teeth 1251 through the chain 1253. The second teeth 1252 may be connected to the cutting portion 11 and transmit a rotational force supplied from the first teeth 1251.

In this way, the cutting device 10 according to the present invention may be coupled to the perforation unit 100 due to the power cutting unit 12. In particular, the cutting device 10 according to the present invention has the effect of being interchangeable with the drilling device 20 to the drilling unit 100 simply and quickly through the chain-shaped power transmission member 125, Due to the chain-shaped power transmission member 125, there is an effect that the cutting device 10 can be miniaturized.

Here, the cutting device 10 does not have its own power source, and receives power through a power source 31 formed outside, that is, formed in the replacement device 30. For this reason, the cutting device 10 of the present invention may be compactly formed without having a separate power source, and may be easily attached and detached. In the present invention, the external power source 31 may be a power source formed in the drilling unit 100, that is, a separate power source formed in the replacement device 30, not driven by pressure oil supplied from the construction machine 1. Of course, the present invention is not limited thereto, and the external power source 31 may be driven by receiving pressure oil from the construction machine 1. However, the cutting device 10 itself does not have a separate power source.

In this case, the outer housing member 131 may be formed such that the diameter of the open end of the lower end gradually decreases in the lower direction.

The outer housing member 131 may be formed so that the cut portion 11 passes through the center of the longitudinal axis, and for this purpose, the outer housing member 131 may have openings formed in the longitudinal direction on both sides of the outer housing member 131. In this case, the outer housing member 131 may be maintained in shape by a member and a fixing member 126 connecting the power transmission unit 12 and the cutting unit 11.
