Description

Fixing device for hydraulic pipe with hydraulic end hose connector {The apparatus for fixed of oil pressure pipe and hose}

The present invention relates to a fixing device for a hydraulic pipe having a hydraulic end hose connector, and in detail, connecting and fixing a hydraulic pipe and a hydraulic hose used when mounting an auto clamping device on an excavator under construction, The present invention relates to a fixing device for a hydraulic pipe having a hydraulic end hose connector, which is prevented from being separated or damaged by severe vibration, thereby preventing a long-term use.

In general, hydraulic equipment such as heavy equipment that is hydraulically operated, such as an excavator, is to operate various actuators provided in the excavator by using the pressure oil discharged from the pump.

Most of the hydraulic oil used in these hydraulic devices are supplied using metal pipes or rubber hoses. In order to allow equipment that performs complex movements with multiple joints, such as excavators, to flexibly move together according to the movement of joints In general, pipes and rubber hoses are used, and the rubber hoses are generally exposed to the outside of the equipment in order to be able to flexibly move the joints of the heavy equipment and to facilitate their installation, replacement and repair. Will be installed.

As such, the hose exposed to the outside is arranged in two or more strands, and in order to connect several actuators, several strands of hydraulic hoses and pipes are connected and fixed together. Due to the frequent break-up or breakage caused by vibration, it causes a lot of troubles, and in the case of hydraulic hose, it should be able to move flexibly according to the rotation of the bucket, but the repair cost is increased by being pressed against other members such as links. There has been a problem.

Korean Patent Publication No. 232085 includes a winding mechanism that is rotated by an automatic or manual driving means, and a movable wheelchair comprising a support means that is moved up and down according to the winding and unwinding of the wire according to the rotation of the winding mechanism. It is about a lifting device for

In Korea Registration Utility Model Publication No. 158778, an assembly pipe is formed at the tip of the rotating body, and an O-ring is placed on the opposite end of the rotating body, and the ball for preventing the release from the inside can be combined. Insert the insertion hole into one side of the sealed tube to be connected, and then connect the connecting nut in double, and the connecting tube is introduced at the outer end where the O-ring and ball of the rotating body are coupled, and the spring and several packings inside the cylinder. It is related to the rotating connector for the hydraulic hose coupled to each other by releasing the connecting pipe on the outside of the cylinder,

The Korean Utility Model Publication No. 1998-11572 fixes a hydraulic hose for heavy equipment, which consists of a hose clamp integrally formed with a plurality of annular portions, one side of which is cut off so that the hydraulic hose is fitted, and a fixing bracket for fixing the clamp to one side of the equipment. To the device,

Korean Laid-Open Model Publication No. 1999-6172 discloses a base member installed on a frame and a corresponding assembly hole formed on each side of another adjacent base member, so that the plurality of base members are fastened through the assembly hole. In connection with the fixed on the frame, in order to prevent the weakening of the frame to any one of the plurality of base members welded to the frame, characterized in that for the hydraulic pipe coupling structure for heavy machinery,

Since the conventional techniques are in a straight line, the movement of the hydraulic hose is unnatural due to the movement of the hydraulic hose, and the hydraulic hose is squeezed or damaged, and only the base member is welded. However, it does not prevent separation of the fastening bolt or the hydraulic pipe. there is a problem.

In order to solve the above problems, the present invention is a fixture for fixing the hydraulic pipe of the hydraulic line to form a bolt groove in the center of the base plate, by attaching a nut so as to penetrate through the bolt groove and welded to the base plate, the bolt Due to the extended length of the fastening, the fastening bolt is loosened due to the vibration generated during the work, or the work loss and safety accidents are prevented due to breakage or breakage of the hydraulic pipe.

Hydraulic end hose connector of the hydraulic line is to improve the device that was connected in the conventional straight direction by installing a fastener and a connector to connect by turning the direction 180 °, by connecting the connector of the hydraulic end hose to the connector, It is a technical object of the present invention to provide a fixing device for a hydraulic pipe having a hydraulic tip hose connector which prevents the hydraulic tip hose from being damaged by crimping with a clamp peripheral member when the excavator moves. .
