Description

Technical Field

[0001] This utility model relates to the field of tensile strength technology for cable protection pipes, specifically a cable protection pipe with tensile strength. Background Technology

[0002] Cable protection pipes often need to withstand tensile and bending forces during installation, especially during long-distance overhead or trenchless construction, where the tensile strength requirements for the pipe body are even higher. Existing protection pipes mainly improve tensile strength by increasing wall thickness or using fiber reinforcement (such as glass fiber), but such designs may lead to increased weight and decreased flexibility. While some metal protection pipes have excellent tensile properties, they suffer from drawbacks such as susceptibility to corrosion, heavy weight, and inconvenient installation. Ordinary plastic protection pipes are prone to creep deformation and even breakage under long-term tensile loads.

[0003] In existing technologies, traditional tensile reinforcement methods (such as simply increasing material usage) struggle to balance the demands for lightweighting and high strength, and the insufficient interfacial bonding of fiber-reinforced protective pipes easily leads to delamination failure. Furthermore, existing technologies have limited research on the resistance to dynamic tension (such as periodic tensile forces caused by earthquakes or geological subsidence), making the pipe prone to microcracks that propagate under repeated stress, ultimately causing structural damage. Therefore, developing a cable protection pipe that combines high tensile strength with flexible adjustment is crucial. Utility Model Content

[0004] The purpose of this utility model is to provide a cable protection pipe with tensile strength, so as to solve the problems mentioned in the background art and overcome its technical defects.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a cable protection pipe with tensile strength, including a protection pipe and a corrugated pipe, wherein the protection pipe and the corrugated pipe are arranged alternately, the protection pipe and the corrugated pipe are hinged by a swivel joint, and a compensation space is provided between the protection pipe and the corrugated pipe for space compensation of the hinge between the protection pipe and the corrugated pipe.

[0006] As a further embodiment of this utility model: a cable protection pipe with tensile strength, further comprising a cable spiral clamp, wherein the cable spiral clamp is fixedly installed on the inner circumference of the protection pipe and the corrugated pipe, and the inner ring of the cable spiral clamp is clamped to the cable.

[0007] As a further embodiment of this utility model: a cable protection pipe with tensile strength, the protection pipe including a fixed protection pipe body and an adjusting protection pipe body, the corrugated pipe including a fixed corrugated pipe body and an adjusting corrugated pipe body, the adjusting protection pipe body being fixedly connected to the fixed protection pipe body, the adjusting corrugated pipe body being fixedly connected to the fixed corrugated pipe body, and the adjusting corrugated pipe body being adapted to the adjusting protection pipe body.

[0008] As a further embodiment of this utility model: a cable protection pipe with tensile strength, wherein the outer periphery of the adjusting protection pipe body and the adjusting corrugated pipe body are both fixedly connected with joints, and the rotating seat is rotatably connected to the joints.

[0009] As a further embodiment of this utility model: a cable protection tube with tensile strength, further comprising a screw, wherein the screw is screwed into a joint and movably connected to a swivel seat.

[0010] As a further embodiment of this utility model: a cable protection pipe with tensile strength, wherein the ratio of the compensation space to the diameter of the corrugated pipe is 0.7:18.

[0011] As a further embodiment of this utility model: a cable protection pipe with tensile strength, wherein the corrugated pipe is made of nylon PA with good tensile properties.

[0012] As a further embodiment of this utility model: a cable protection tube with tensile strength, wherein the protection tube, the rotating seat, the joint and the screw are all made of wear-resistant polyurethane (PU).

[0013] Compared with the prior art, the beneficial effects of this utility model include:

The compensation space 4 is used to compensate for the space of the hinge between the protective tube 1 and the corrugated tube 2. Specifically, the protective tube body 12 is fixedly connected to the fixed protective tube body 11, the corrugated tube body 22 is fixedly connected to the fixed corrugated tube body 21, and the corrugated tube body 22 is adapted to the protective tube body 12.
