Description

[0001] VARIABLE TYPE CHIPPING ATTACHMENT DEVICE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable chipping attachment device, and more particularly, to a variable chipping attachment device capable of easily adjusting a chipping position according to a working environment and performing a chipping operation of a selected area quickly and precisely.

Generally, chipping refers to the removal of unnecessary parts by cutting the surface of an object such as metal or concrete. In the case of concrete, it is a phenomenon in which the surface is laitance, It has been necessary to remove these unnecessary parts since the paint which is applied to the paint weakens the adhesion force and deteriorates the water tightness (water tightness, water penetration, absorption, property to prevent permeation).

Particularly, when the condition of the road surface becomes poor, such as pumping phenomenon or crack caused by weakening of bearing capacity of a roadbed, or plastic deformation due to load of a vehicle, the existing bad road surface is broken, and then, asphalt or cement . In order to improve adhesion and watertightness, a chipping operation using a water jet system is performed prior to packaging.

The water jet system comprises a power pack for generating ultra-high-pressure water, a high-pressure hose for delivering ultra-high-pressure water from the power pack, and an injection nozzle for jetting ultra-high-pressure water supplied through the high-pressure hose toward the target surface. It is mainly used for chipping work because it can reduce the incidence, prevent damage of reinforced concrete placed in concrete, and selectively remove only the parts requiring repair.

Conventionally, since it is difficult to change the position of the injection nozzle according to the working environment, the time required for the chipping operation is increased. Therefore, there is a need for improvement.

The background art of the present invention is disclosed in Korean Patent Registration No. 10-0705356 (April, 09, 2007, entitled "Chipping device of water jet system").
