When oil tank, hydraulic pump or pipeline needs to be repaired, the whole unit needs to be disassembled or operated in narrow space, which is time-consuming and labor-intensive and easy to damage seals. In addition, fixed design is difficult to adapt to frequent maintenance scenarios (such as on-site repair of engineering machinery), which reduces equipment availability. Some improved designs use sliding rails or movable supports to realize push-pull repair of hydraulic power unit, but do not effectively solve the problem of oil pipe management. Because the oil outlet pipe and the oil return pipe are long and lack of winding structure, the pipe is easy to wind, bend and even rub with surrounding parts during movement, which accelerates the aging of the pipe and causes leakage risk.

[0004] Therefore, we provide an installation support frame for hydraulic power unit to solve the above problems. CONTENT OF THE UTILITY MODEL
