Description

Excavator having movable multi-drill}

The present invention relates to an excavator, and more particularly, to an excavator for heavy equipment equipped with a multi-drill (Multi-drill) having a plurality of drills for drilling the ground or rock, mounted on heavy equipment such as excavators.

In general, the excavator for heavy equipment is mounted on a link provided at the end of the arm of the heavy equipment such as the fork-lane is used for drilling the ground or rock during civil engineering.

Figure 1 schematically shows the configuration of a excavator for heavy equipment according to the prior art. The excavator for heavy equipment disclosed in Korean Laid-Open Patent Publication No. 2005-35488 is provided with a core tube 20 having a main body 10 connected to a link of heavy equipment, and a drill bit 21 at a lower portion thereof. The hydraulic motor 30 for rotating the core tube 20 receives hydraulic pressure from the hydraulic supply unit of heavy equipment, the driving motor 40 for raising and lowering the core tube 20, the rack 42 and the pinion ( Pinion (43) gears.

The excavator having the above configuration rotates the core tube 20 by driving the hydraulic motor 30 in a state where the drilling bit 21 under the core tube 20 is positioned at the excavation target point, and drives the drive. By operating the motor 40, the sliding plate 41 supporting the core tube 20 is lowered to proceed the excavation to a desired depth. The pinion 43 rotates through the belt 44 during the operation of the drive motor 40, and the sliding plate 41 is the rack 42 due to the mechanical interaction between the rotating pinion 43 and the rack 42. By moving along the core tube 20 is lowered.

By the way, the excavator equipped with a single core tube as described above should be carried out by moving the core tube to all excavation targets one by one, so not only the work speed is slow, but also fine adjustment for moving the core tube to the desired point one by one. It is not easy, since the upper rotor of the heavy equipment to move frequently to move the core tube has a problem of poor workability. In practice, when a plurality of holes are drilled at a predetermined interval using a single core tube, swing operation or forward / reverse driving frequently rotating the upper rotor of the heavy equipment to the left or right should be frequently performed. Incorrect work is often caused by incorrect alignment, and fuel consumption is very long and the work time is very long.

In addition, an excavator equipped with a single core tube has a disadvantage in that the core tube breaks and the work is inevitably stopped when the core tube is replaced with another core tube or another core tube with a different diameter for drilling. There is this.

Alternatively, the Republic of Korea Patent Publication No. 602162 has a support plate partitioned into a plurality of core tube installation space, each core tube installation space can be installed at the same time through a single drilling operation by installing a core tube in a plurality of holes A rock drilling device is disclosed. As such, when a plurality of core tubes are mounted and used simultaneously, the drilling efficiency and workability can be improved.

The rock mill mill is equipped with an upper fixing plate and a connecting plate at the upper ends of both support plates forming a plurality of core tube installation spaces, and an excavator coupling hole is formed at the upper portion of the connecting plate and is connected to the link portion of the excavator to be mounted on the excavator. However, according to this structure, as in a conventional excavator bucket, a plurality of core tubes can be moved collectively only by the "pruning" and "unfolding" operations, thereby moving the plurality of core tubes to a desired working position. In order to achieve this, there is a vulnerability that requires swinging the upper rotor of heavy equipment or frequently performing forward / reverse driving. As a result, when the core tube array including a plurality of core tubes is not accurately adjusted to be moved, work defects often occur, and as with a single core tube, fuel consumption is high and difficulty in alignment There is a vulnerability that takes a very long time. On the other hand, it is difficult to move the core tube array in accordance with the swing operation only because it is difficult to move the heavy equipment straight forward or backward due to the terrain conditions, there is also a problem that it is impossible to move the core tube array exactly straight. For example, as shown in FIG. 2, when the upper rotary body of heavy equipment is swinged to move the core tube array 1 to P point, a deviation occurs between the moving position of the core tube array 1 and the P point line. This can lead to malfunction.

SUMMARY OF THE INVENTION An object of the present invention is to provide a fabric mill for an excavator equipped with a multi-drill having a structure that is mounted on the link portion of heavy equipment and that can be horizontally moved without swinging the upper rotating body of the heavy equipment.
