Problems solved by technology

The existing problems are: because the low-carbon steel strips are wound into a helical spring shape, the dimensional stability is not good, and it is easy to elongate, causing the hose to break; because the outer layer of rubber is thick, it is not resistant to folding and is not soft, and the softness is not easy to control, and More materials are used, because the surface inside the tube is relatively smooth, the lubricating oil is easy to flow off, causing dry friction, wasting energy, low production efficiency, high cost, not durable, and short service life

Abstract

The invention belongs to the technical field of construction machinery, and specifically relates to a mechanical hosepipe. A large-pitch spring 1 is movably connected with a double-buckle galvanized spiral snakeskin tube 2, and the double-buckle galvanized spiral snakeskin tube 2 is fixedly connected with a rubber tube 4, and large-pitch spring 1, the double-buckle galvanized spiral snakeskin tube2 and the rubber tube 3 are tightly integrated. The cross section of an inner layer is a circle with the diameter being 2-20 mm, or rectangular, and high carbon steel strips or steel wires with widthand thickness of 2-20 mm are made into the large-pitch spring 1 with a pitch from 2 mm to 50 mm according to the diameter of the double-buckle galvanized spiral snakeskin tube. The middle layer is the double-button galvanized spiral snakeskin tube 2 made of low carbon steel sheets, copper plates and stainless steel plates with thickness of 0.5-4 mm, and the pitch of the double-button galvanized spiral snakeskin tube 2 is 2-20 mm. The outer layer is made of the NBR tube 4 or a rubber -plastic tube sandwiched with cord fabric 3, the thickness of the inner layer of the rubber tube 4 is 0.1-1 mm,the thickness of the cord fabric 3 is 0.01-1 mm, and the thickness of the outer layer is 1-20 mm.

Description

technical field [0001] The technology belongs to the technical field of construction machinery, in particular to a mechanical hose. Background technique [0002] Today's mechanical hoses are usually constructed of two layers: an inner layer of mild steel strips wound into a coil spring shape, and an outer layer of thick rubber with a ply. The existing problems are: because the low-carbon steel strips are wound into a helical spring shape, the dimensional stability is not good, and it is easy to elongate, causing the hose to break; because the outer layer of rubber is thick, it is not resistant to folding and is not soft, and the softness is not easy to control, and Also many materials are used, and because the surface in the pipe is relatively smooth, the lubricating oil is easy to flow off, causing dry friction, wasting energy, low production efficiency, high cost, not durable, and short service life. Contents of the invention [0003] In order to overcome the above exis...
