Abstract

An apparatus for fixing hydraulic pipes for construction equipment is provided, which can facilitate joint connection of return pipes having a large size to a hydraulic tank (2), in an environment where a working space of an upper frame (6) is narrow such as in a small swing radius construction equipment, by a return pipe block (13) for returning hydraulic fluid of a main control valve (1) to the hydraulic tank (2) without being interfered with a swing motor (4) and so on. The apparatus for fixing hydraulic pipes includes a first return joint pipe (10) having an inlet port joint-connected to a main control valve (1), a second return joint pipe (11) having an outlet port joint-connected to an oil cooler (5), a return pipe block (13) mounted on an upper frame (6) between a frame to which a working device is fixed and a swing motor (4), and joint-connected to an outlet port of the first return joint pipe (10) and an inlet port of the second return joint pipe (11), respectively, and a third return joint pipe (14) having an inlet port joint-connected to the return pipe block (13) and an outlet port joint-connected to the hydraulic tank (2).
The return pipe block (13) is mounted on the upper frame (6) to joint-connect the first and second return joint pipes (10,11), and the third return joint pipe (14) is joint-connected to the return pipe block (13) and the hydraulic tank (2), respectively, after the swing motor (4) is mounted on the upper frame (6).
