An outrigger oil circuit system

Abstract

The invention provides a support oil circuit system which comprises a movable support box and a fixed support box, wherein the movable support box is sleeved by one inner end of the fixed support box; a set of oil circuit components are arranged on the fixed support box and the movable support box, and comprise an oiling block I, an oiling block II and a partition plate connector; the oiling block I is fixed in the fixed support box and used for introducing an external oil source into the fixed support box; the oiling block II is fixed under the tail end surface of the movable support box; the oiling block I and the oiling block II are connected through a hose; the partition plate connector is fixed inside the movable support box, and connected with the oiling block II through a hard tube; and meanwhile, the partition plate connector is connected with a hydraulic lock of a vertical oil cylinder through a connecting tube. Compared with the prior art, the support oil circuit system provided by the invention has the advantage that the problem about difficulty in the oil circuit trend of a manual support box can be effectively solved, and is successfully applied to small-sized engineering equipment.

Description

technical field [0001] The invention relates to a structural layout of the horizontal outrigger oil passage direction. Especially for the direction of the hydraulic oil circuit without oil cylinder for rigid guidance when the manual horizontal outrigger box is telescopic, it is suitable for the equipment that introduces the oil circuit into other actuators through the horizontal telescopic outrigger box. The power oil source is introduced into the vertical outrigger hydraulic cylinder through the horizontal outrigger box. Background technique [0002] Horizontal outriggers and vertical outriggers are ubiquitous in construction machinery and equipment, and the current main technologies are as follows. [0003] (1) Full-hydraulic automatic expansion and contraction of hydraulic oil delivered by steel pipes outside the horizontal cylinder. Such as figure 1 As shown, the direction of the oil path of the horizontal outrigger and the vertical outrigger is transmitted by the ste...

Problems solved by technology

Although Method 4 provides a manual outrigger oil circuit direction, it still has the following disadvantages: First, the section of the movable outrigger box is quite different from that of the fixed outrigger box. The gap between the sections is large, there will be upturning when the force is applied, and the force is concentrated on the end surface, which has a discount on the structural performance

Second, when pulling out and pushing back, the rubber hose will rub against the pulley bracket at the end of the movable outrigger box, which is easy to damage the hose, especially when pushing the outrigger box, the oil pipe should fall between the movable outrigger box and the fixed outrigger box In the small gap, the edge of the tail of the upper plate of the movable outrigger box forcibly pushes the rubber hose, which makes the local bending radius of the rubber hose too small and the force is too large, and also damages the rubber hose to a certain extent, affecting the use and life.
