The present invention relates to an automatic device for cleaning the head of concrete piles, and more particularly, to automate cutting and grinding work, which accounts for more than 80% of the total work cycle time, in order to reduce time and work cycles. The present invention relates to a tofu cleaning automation device that improves productivity through reduction.

Ready-made concrete pile foundations are commonly used in large-scale construction and civil engineering works, and the demand is continuously increasing as more and more buildings are being weighted, large-scaled, and high-rise, and construction of structures on soft ground has increased. In Korea, the demand for reclamation projects, apartment houses, and multi-composite buildings, which mainly use ready-made concrete pile foundations, is expected to increase in the future.

The ready-made concrete pile construction is classified into pile inspection, excavation and pile purchase, and tofu cleanup.In the case of pile tofu cleanup, if the crack occurs in the process of crushing the concrete pile, the pile strength of the part connected to the foundation is remarkably increased. In addition, it is difficult to secure sufficient bearing strength to support the building, and it is difficult to maintain the uniformity of concrete pile quality because it is impossible to adequately cope with invisible cracks that are difficult to identify.

In particular, the results of recent field work observations show that when crushing the head using a crusher, the principle is to crush it from the head cutting section to the 1D point. Because it occurs, the concrete is being crushed close to the cutting line, which means that the steel wire of the pile is excessively pulled in the process of crushing the concrete with the crusher, causing cracks on the inside and outside of the bottom and greatly affecting the quality of the tofu cleanup. In addition, this crack is a major cause of air delay and increase of construction cost since it requires reinforcement work after the tofu cleanup work.

On the other hand, cutting work using a grinder during tofu cleaning involves the risk of electric shock, and the cutting of steel wires may cause injury to workers due to the use of cutters and hydraulic cutters. Therefore, the work is performed in a weak working environment where safety is not secured, and there is an urgent need for the development of an automated technology capable of performing tofu cleanup work in a safe working environment.

In order to solve the problems described above, the present invention analyzes the process of arranging the head of the concrete pile to improve productivity and quality by automating the cutting and grinding work that requires a relatively longer working time and input time than other work Its purpose is to provide an automatic tofu cleanup device that reduces work time and costs.

In order to achieve the above object, fixing of end-effector and concrete pile and rotating around piles with cutting technology that can grind on cutting line and shredding technology that can break up the upper and the head clearance surface. There is a technical problem that requires the basic mechanism of the automation equipment for tofu cleansing.

Referring to the work process of the tofu cleanup device configured as described above are as follows.

First, the excavator is connected to the link unit 50 of the tofu cleanup device to be inserted into the upper PHC pile 700 to work, and the cutting surface of the PHC pile 700 with a leveling sensor provided separately on one side of the tofu cleanup device. When it recognizes, it generates a beeping sound, and the hydraulic supply device is activated to supply hydraulic pressure to the equipment. When the hydraulic pressure is supplied, the holder is operated to fix the PHC pile 700 to coincide with the center of the equipment and the center of the PHC pile 700. The inserted PHC pile 700 has a holder frame 46 of the holder portion 40. One vertical surface is in close contact with), and the hydraulic cylinder 44 provided at the other side is driven to fix the holder block 421 of the holder plate 42 to the other vertical surface of the PHC pile 700.

The fixed PHC pile 700 drives the hydraulic cylinder 36 of the cutting unit 30 to advance the lower grinder cover 31 connected to the support shaft 33 and to rotate the grinder 32 mounted therein. By cutting the grinding mark on the head clearance surface by using the blade, the base frame 10 is cut in the forward direction by the rotational force of the gear 471 and the turntable bearing 49 of the hydraulic motor 47, and then the link portion ( The stopper 53, which is a forward stop sensor provided in 50), stops rotation, and then rotates in the reverse direction again to return to its original position.

When the cutting operation is completed, the hydraulic cylinder 21 of the crushing unit 20 is driven to perform a horizontal reciprocating motion of the crushing bracket 23 so that the crushing blade 26 on the front of the crushing bracket 23 is PHC pile 700 After breaking the PHC pile 700 into four bands in four directions of), the breaker 27 sequentially crushes the PHC pile 700 on the crushing blade 26, and the rotational force of the turntable bearing 49.
