Abstract

The invention provides a tensile hose. The tensile hose comprises a force bearing inhaul cable, a joint connecting piece and at least one hose body, a hose hoisting and pulling force application joint is arranged on each hose body, an inhaul cable force application joint is arranged on the force bearing inhaul cable, and the joint connecting piece is used for connecting the hose hoisting and pulling force application joint and the inhaul cable force application joint. An assembly used for enhancing the strength of a hose comprises the hose hoisting and pulling force application joint and a joint connecting piece, the hose hoisting and pulling force application joint comprises a hose connector, and the joint connecting piece is provided with a first connecting part used for pulling the hose connector and a second connecting part used for pulling the force bearing inhaul cable. The tensile property of the hose in the axial direction can be improved under the condition that the compression strength and the radial deformability of the hose are achieved.

Description

technical field [0001] The invention relates to the technical field of hoses, in particular to a stretch-resistant hose and components for enhancing the strength of the hose. Background technique [0002] Compared with rigid pipes, hoses have high deformability and are easy to install and maintain. Theoretically, the higher the radial deformability of the hose, the better, but the higher the radial deformability of the hose, the higher its stretchability in the axial direction. If the hose is longer When the hose is pulled by its own weight, it may cause damage to the hose. For this reason, the axial tensile strength of the hose is generally improved by setting reinforcing ribs in the pipe wall of the hose. Common reinforcing ribs include spiral steel wires and composite material rope nets. However, the material of the reinforcing rib is different from that of the hose, and its combination is poor, which will reduce the compressive strength of the hose. [0003] The oil c...
