Abstract

The invention provides a constructional engineering optical cable impact testing device and testing method, and belongs to the technical field of optical cable tests. The constructional engineering optical cable impact testing device comprises a testboard, stand columns and a conveying mechanism, the stand columns are vertically and symmetrically arranged at the top of the testboard, and the conveying mechanism is arranged at the top of one side of the testboard; and symmetrical clamping mechanisms are arranged at the top of the other side of the testboard, an impact table is arranged between the clamping mechanisms; each clamping mechanism comprises a U-shaped fixing plate, a threaded rod, a fixed clamping block and a movable clamping block, and the U-shaped fixing plates are fixedly arranged at the top of the testboard. A mounting block and an impact hammer on the mounting block can be moved to a proper height through a lifting mechanism so as to adapt to impact tests of optical cables with different heights, and a fixing mechanism for fixing and releasing the impact hammer is arranged on the mounting block so as to avoid defects caused by traditional rope traction; in addition, the conveying mechanism is arranged, so that the optical cable can be conveyed conveniently.

Description

technical field [0001] The invention relates to the technical field of optical cable testing, in particular to a construction engineering optical cable impact testing device and a testing method thereof. Background technique [0002] Fiber optic cable is manufactured to meet optical, mechanical or environmental performance specifications. It uses one or more optical fibers placed in a sheath as the transmission medium and can be used individually or in groups. Communication cable assemblies, summed up , Optical cable is a communication line in which a certain number of optical fibers form a cable core in a certain way, and is covered with a sheath, or covered with an outer sheath, to realize optical signal transmission. Optical cables play an important role in modern communication infrastructure. As a neural network in the 5G era, the demand is constantly growing. In view of the variety of environments in which optical cables are used, the requirements for reliability and m...
