Auxiliary device for detecting overall tensile property of silicon core tube and detection method

Abstract

The invention discloses an auxiliary device for detecting the overall tensile property of a silicon core tube and a detection method, and relates to the technical field of silicon core tube performance detection equipment, the auxiliary device comprises an outer shell and an inner rod body arranged in the outer shell; the outer shell comprises a first shell body, a second shell body and a lockingpiece used for connecting the first shell body and the second shell body. Grooves with semicircular sections are formed in the surfaces of the opposite sides of the first shell body and the second shell body correspondingly, and the inner rod body is arranged in a space formed by the two grooves in a penetrating mode. The radius of the inner rod body is smaller than that of the groove, and a gap for accommodating the silicon core tube is reserved between the outer peripheral surface of the inner rod body and the inner wall of the groove; the length of the inner rod body is larger than that ofthe groove. The success rate of the test can be effectively improved, and the silicon core sample is saved.

Description

technical field [0001] The invention relates to the technical field of silicon core tube performance testing equipment, in particular to an auxiliary device and a testing method for testing the overall tensile performance of a silicon core tube. Background technique [0002] High-density polyethylene silicon core plastic pipe, also known as silicon core pipe, is often used as a highway underground communication pipeline. It is a new type of composite pipeline with silicone solid lubricant on the inner wall. It has good sealing performance, chemical corrosion resistance and low engineering cost. Therefore, Widely used in highway optical cable communication network system. [0003] The overall tensile performance is an important physical and chemical property of the silicon core tube. Since the cable is in a suspended state in the pipeline and moves at a high speed, the silicon core tube needs to have a certain tensile performance to prevent the cable from being caused by stre...

Problems solved by technology

[0004] In the above testing process, the two ends of the silicon core tube are clamped by the clamp of the tensile testing machine, but since the silicon core tube is hollow, when the two ends of the silicon core tube are clamped on the clamp, deformation will occur, and the silicon core sample will be deformed. The two ends are easily broken at the edge of the fixture, resulting in invalid experiments, and the sample needs to be replaced for testing. Not only the success rate of the test is too low, but also a large amount of silicon core samples are consumed
