Problems solved by technology

[0004] At present, the detection of transverse rigidity value of tubular conveyor belt is mainly based on HG / T4225-2011 "Fabric Core Tubular Conveyor Belt" and HG / T4224-2011 "Steel Cord Tubular Conveyor Belt" standard appendix A (normative appendix) "Tubular Belt Transverse Rigidity Value Test Method", the above methods are all static test methods, but there is a temporary lack of relevant standards for the test method of dynamic flex fatigue performance of tubular conveyor belts

Embodiment 1

[0025] The dynamic flex fatigue performance test of 2 tubular conveyor belts with a skeleton material of canvas and a pipe diameter of 500mm.

[0026] The detection method of the dynamic flex fatigue performance of the tubular conveyor belt includes the following steps:

[0027] (1) Stand still: take the tubular conveyor belt, and prepare a tubular conveyor belt sample of a certain length, and the sample length is 500 mm. Place it in an environment with a temperature of 22-24°C for more than 4 hours before testing;

[0028] (2) Adjustment: Adjust the pipe diameter of the tubular conveyor belt to 500mm;

[0029] (3) Test: The prepared sample is installed on the tubular conveyor belt dynamic flex fatigue testing machine, so that the center line of the overlapping part of the tubular conveyor belt is aligned with the center line of the pressure roller on the tubular conveyor belt dynamic flex fatigue testing machine; adjust the sample to In a balanced position, set the displace...

Embodiment 2

[0034] Three skeleton materials are steel wire ropes, and the dynamic flexion fatigue performance test of tubular conveyor belts with a pipe diameter of 450mm. The core rubber thicknesses of samples A, B, and C are 1mm, 4mm, and 6mm respectively, and the rest of the materials and specifications are the same.

[0035] The detection method of the dynamic flex fatigue performance of the tubular conveyor belt includes the following steps:

[0036] (1) Stand still: take the tubular conveyor belt, and prepare a tubular conveyor belt sample of a certain length, and the sample length is 450 mm. Place it in an environment with a temperature of 22-24°C for 12 hours before testing;

[0037] (2) Adjustment: Adjust the pipe diameter of the tubular conveyor belt to 450mm;

[0038] (3) Test: The prepared sample is installed on the tubular conveyor belt dynamic flex fatigue testing machine, so that the center line of the overlapping part of the tubular conveyor belt is aligned with the cente...

Abstract

The invention provides a method for detecting the dynamic flexural fatigue performance of a tubular conveyor belt, which comprises the following steps: (1) standing: preparing a tubular conveyor belt sample, and standing for more than 2 hours in an environment at the temperature of 22-24 DEG C before testing; (2) adjusting: adjusting the pipe diameter of a finished pipe of the dynamic flex fatigue testing machine for the tubular conveying belt according to the pipe diameter of the sample; and (3) testing: mounting the sample prepared in the step (1) on a dynamic flex fatigue testing machine for the tubular conveying belt, aligning the central line of the lap joint part of the tubular conveying belt with the central line of a compression roller on the dynamic flex fatigue testing machine for the tubular conveying belt, adjusting the sample to a balanced position, and performing a dynamic flex fatigue test. According to the method for detecting the dynamic flex fatigue performance of the tubular conveyor belt, the blank of the method for testing the dynamic fatigue of the tubular conveyor belt is filled, continuous long-time periodic dynamic testing is adopted, and errors of measurement results caused by contingency of personnel and machines in the single static testing process are avoided.

Description

technical field [0001] The invention relates to the technical field of conveyor belt detection, in particular to a detection method for the dynamic flex fatigue performance of a tubular conveyor belt. Background technique [0002] Tubular conveyor belt is a new type of conveyor belt used for material transmission, mainly used for conveying powdery, granular and other easily polluted materials. It is opened at the head and tail of the conveyor for feeding and discharging; while it is bent into a tube during the conveying stage to seal the feeding. [0003] In recent years, tubular conveyor belts have developed rapidly in many industries due to their advantages such as good sealing, turnability, two-way transportation, and flexible arrangement. Although the tubular conveyor belt is still a flat conveyor belt, it needs to be bent into a round tube during the conveying process to ensure airtightness, and it is required to be bent into a tube many times during the long-term tran...
