Problems solved by technology

[0002] The existing piping systems between the oil cylinders of forklifts all use n-type piping systems. This type of n-type piping contains more connecting pipe joints, making it more likely to cause oil leakage after long-term use At the same time, the original n-type tube uses high-pressure rubber hose to connect the hy

Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing:

[0019] like Figure 1-7 The shown adjustable special-shaped hard-connected hydraulic pipeline suitable for narrow spaces includes a special-shaped high-pressure steel pipe assembly 7 arranged in the space formed between the outer mast beam 5 and the bottom of the axle housing bulge 6. The special-shaped high-pressure The steel pipe assembly 7 is bent and arranged along the outer contour of the axle housing bulge 6, and is close to the inside of the outer mast beam 5. The two ends of the special-shaped high-pressure steel pipe assembly 7 are horizontally bent and arranged, and the special-shaped high-pressure steel pipe assembly 7 is about The vertical central axis of the pipe body is symmetrically arranged, and the middle part of the special-shaped high-pressure steel pipe assembly 7 is concave-convex and bent along the outer contour of the axle housing bulge 6 to avoid the co

Abstract

The invention discloses an adjustable abnormal-shaped hard connecting hydraulic pipeline suitable for a narrow space. The adjustable abnormal-shaped hard connecting hydraulic pipeline comprises an abnormal-shaped high-pressure steel pipe assembly arranged in a space region formed between an outer portal frame crossbeam and the bottom of an axle housing bulge, wherein the abnormal-shaped high-pressure steel pipe assembly is bent along the peripheral outline of the axle housing bulge; a nut is in threaded connection to each connector core; and the axis length of the connector cores is greater than or equal to that of the nuts. According to the adjustable abnormal-shaped hard connecting hydraulic pipeline disclosed by the invention, through the design of the adjustable abnormal-shaped hard connecting hydraulic pipeline, the length of the pipeline is substantially reduced, and the effect that the pressure loss of the pipeline is reduced is achieved; two ends are connected with the hydraulic cylinder through a steel pipe assembly, so that the heat dissipation performance is substantially improved; the abnormal-shaped high-pressure steel pipe assembly adopts a curve structure design, sothat the effect of directly connecting a left side oil cylinder with a right side oil cylinder is fundamentally achieved; a structure that each pipe connector nut is adjustable in the axial directionof the corresponding connector core shaft in a large range is adopted, so that the production and assembly are convenient, and the efficiency is high; and besides, in the hydraulic pipeline system, aprospective sealing effect can be achieved.
