PE pipe quality detection and positioning instrument

Abstract

A pe pipe quality detection and positioning instrument comprises a first supporting plate, a second supporting plate, a third supporting plate, a fourth supporting plate, a positioning assembly and a pe pipe. The second supporting plate, the third supporting plate and the fourth supporting plate are arranged on the first supporting plate, and an electric telescopic rod is arranged on the fourth supporting plate. A first cylinder is arranged on the second supporting plate, and multiple sets of first through holes are formed in the first cylinder; the first clamping rods penetrate through the first through holes in a matched manner; and a first ball head is rotationally arranged at one end of the first clamping rod. The inner circumferential wall of the pe pipe makes contact with the multiple sets of first clamping rods, a second cylinder is arranged on the second supporting plate, and multiple sets of second through holes are formed in the second cylinder. A second clamping rod is attached to the peripheral wall of the pe pipe, a second ball head is arranged at the end part of the second clamping rod, and two sets of positioning assemblies are arranged. According to the invention, even if the pe pipe is deformed in the quality detection process, the clamping and positioning effects cannot be influenced; and meanwhile, the third supporting plate can slide, so that the pe pipe quality detection and positioning instrument is suitable for the PE pipes with different lengths.

Description

technical field [0001] The invention relates to the technical field of PE pipe detection, in particular to a PE pipe quality detection and locator. Background technique [0002] Compared with steel pipe, PE pipe has simple construction process and certain flexibility. What’s more, it is not used for anti-corrosion treatment, which will save a lot of processes. Exposed to the air and sunlight, and sensitive to chemicals, it is necessary to prevent leakage of sewage pipes. In order to ensure the normal use of PE pipes, the quality of PE pipes needs to be inspected. The main items of PE pipe quality inspections include flat test, hydrostatic light test, tensile strength test, elongation at break test and drop weight impact test. During the quality inspection process, one or both ends of the PE pipe need to be clamped and positioned. The existing clamping and positioning device is clamped by external pressure. This method is likely to cause clamping and positioning failure due ...

[0002] Compared with steel pipe, PE pipe has simple construction process and certain flexibility. What’s more, it is not used for anti-corrosion treatment, which will save a lot of processes. Exposed to the air and sunlight, and sensitive to chemicals, need to prevent leakage of sewage pipes

In order to ensure the normal use of PE pipes, the quality of PE pipes needs to be inspected. The main items of PE pipe quality inspections include flat test, hydrostatic light test, tensile strength test, elongation at break test and drop weight impact test. During the quality inspection process, one or both ends of the PE pipe need to be clamped and positioned. The existing clamping and positioning device is clamped by external pressure. This method is likely to cause clamping and positioning failure due to deformation of the PE tube and affect the quality. The inspection is carried out smoothly, and it is time-consuming and labor-intensive to re-clamp again
