Problems solved by technology
That is, due to the repeated swinging operation of the boom 6, the external alignment state of the hydraulic hoses 9 and 10 becomes poor when the hydraulic hoses 9 and 10 are twisted or bent, and this may cause damage to the equipment within a short operating time
[0009] In addition, since it is difficult to align corresponding hydraulic hoses due to the addition of various optional devices required by the equipment user, the number of optional devices that can be additionally installed on the equipment is limited
On the other hand, since the hydraulic hoses 9 and 10 are disposed on the outside to be exposed, there is a limit in protecting the hydraulic hoses 9 and 10 from external impact during traveling or working of the equipment.

Disclosed is a hydraulic line fixing apparatus which arranges a hydraulic hose for the attachment of a boom swing-type excavator and a hydraulic hose for additional optional equipment at a preset position in a boom supporter. The hydraulic line fixing apparatus according to the present invention comprises: a clamp defining mounting slots on which a hydraulic hose for attachments including a boom and a hydraulic hose for additional optional equipment are mounted so as to enable the hydraulic hose for the attachments and the hydraulic hose for additional optional equipment to be arranged at a preset position in a boom supporter; and a hydraulic hose fixing cover which is detachably fixed to the clamp by means of a fastening member so as to prevent the separation of the hydraulic hoses from the mounting slots, and to prevent contact of the hydraulic hoses with a boom cylinder fixing member when work fluid is supplied to the hydraulic hoses and flows toward the boom cylinder.
Description
technical field [0001] The invention relates to a hydraulic pipe fixing device for a boom swing excavator. More particularly, the present invention relates to a hydraulic pipe fixing device for a boom swing type excavator, in which a boom support is installed at a front end portion of an upper frame to swing, which is used for an attachment device such as an arm hydraulic hoses for additional optional devices such as swivels are provided in predetermined positions within the boom support, thus improving the work of setting up and assembling hydraulic hoses for attachments and optional devices ability. Background technique [0002] Such as figure 1 and 2 As shown, prior art hydraulic pipe fixing devices for boom swing excavators include: [0003] boom support 4, which is mounted on the front end portion of the upper frame 1 to be swiveled by the upper pin 2 and the lower pin 3; [0004] boom 6 and boom cylinder 7, which are rotatably mounted on the boom support 4 via fix...
