Simplified Attachment Piping of Construction Equipment

The present invention relates to a working device of an excavator that is easy to clean up the hydraulic hose, easy to clean up the hydraulic hose to connect the hydraulic hose connected to each cylinder of the working device through the boom using a terminal block. It relates to an excavator working device.

In general, an excavator is composed of an upper turning body, a lower driving body, and a work device, each of which is connected by a hydraulic hose, which requires a large force such as digging, chopping, and picking by simply operating the lever inside the cab. Heavy equipment used for work.

The upper swing structure of the excavator is provided with an engine, a pump, a fuel tank, and a hydraulic oil tank, and the main hydraulic pressure is used to deliver hydraulic oil to a work device and a lower driving body, which receive hydraulic pressure from them and perform various tasks. A hose and a pilot hydraulic hose are installed to guide the hydraulic system.

In the past, the main hydraulic hoses supplying hydraulic pressure from the main control valve to the cylinder of the work machine performing the direct work are connected to the outside of the work machine by using a pipe, so the hydraulic hoses are exposed to the rough environment where the excavator is located. While such an external environment has been a cause of various problems such as rust generation and breakage of hydraulic hoses and pipes, and to prevent such a problem, there was an inconvenience of installing a protector or the like separately on the hose.

The present invention for solving the above problems, when working in rough terrain by connecting the hydraulic hose for delivering hydraulic fluid to the cylinder portion of the working device to the boom and the arm of the working device using a terminal block, or the equipment for a long time It is to eliminate the problem of hose breakage or rust that may occur when exposed to the outside. Furthermore, the pipes and hoses that are exposed to the outside are installed and arranged inside the work equipment to enhance the appearance of the excavator. The present invention provides an excavator working device that can easily arrange a hydraulic hose.

The present invention to achieve the object as described above and to solve the problems of the conventional, the boom, the boom cylinder for operating the boom, the arm connected to the boom and the arm cylinder for operating the arm, the arm In the excavator working device comprising a bucket and a bucket cylinder for operating the bucket connected to, the boom and the arm is formed inside the hollow so that the hydraulic hose can be piped therein, the boom and the arm inside It characterized in that the terminal block is installed so that the hydraulic hose can be piped to the hollow portion.

In addition, the terminal block is provided with a plurality of ports so that the hydraulic hose can be piped through the hollow portion of the boom and is piped to the hollow portion of the boom through the first terminal block and the first terminal block installed in the boom. It is characterized in that it comprises a second terminal block is provided with a plurality of ports and installed in the boom so that the pressure oil provided through the hydraulic hose is supplied to each cylinder and the breaker.

As described above, according to the present invention, since the hydraulic hose is piped inside through the hollow part of the boom, it prevents damage to the hydraulic hose during operation and eliminates rusting, and guides the hydraulic hose through the pipe, thereby simplifying installation. It is made, and the hydraulic hose is piped into the interior of the boom is a very useful invention that cleans up the appearance of the excavator by arranging various hydraulic hoses.

Hereinafter, the configuration and the operation of the embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.
