Embodiment Construction

[0017] The present invention will be further described below in conjunction with drawings and embodiments.

[0018] Such as figure 1 and figure 2 As shown, the present invention includes a pair of fatigue test fixtures 1 and a seawater tank 2, and the end faces of a pair of fatigue test fixtures 1 are relatively horizontally arranged in both ends of the seawater tank 2. The fatigue test fixture 1 includes a fixture body 11 and a fixture cross pin 12. The fixture body 11 is integrally processed by forgings, including a sequentially connected fork-shaped end 111, a middle cylindrical section 112 and a tail plate 113, which are immersed in the seawater of the seawater tank 2 The ring body 31 at one end of the three-link sample 3 is inserted into the fork-shaped end 111, and is connected to one end of the three-link sample 3 through the clamp cross pin 12 passing through the fork-shaped end 111 and the ring body 31. The longitudinal ends of the seawater tank 2 are respectively ...

Abstract

The invention discloses a marine engineering mooring anchor chain fatigue test device, which comprises a pair of fatigue test fixtures and a seawater tank. The pair of fatigue test fixtures are horizontally arranged in both ends of the seawater tank. , the two ends of the three-link sample immersed in the seawater of the seawater tank are respectively connected to one end of the fixture body through the horizontal pin of the fixture, and the other end of the fixture body protrudes out of the seawater tank, and are respectively connected to the fixed clamping end of the horizontal fatigue testing machine or Active clamp end connection. The lower side of the seawater tank is supported in the frame of the horizontal fatigue testing machine by several floating support mechanisms. The invention has simple structure and convenient operation, can prevent the leakage of seawater in the seawater tank, can carry out the fatigue test of the mooring anchor chain of marine engineering in seawater, and solves the difficult problem of performing the fatigue test on the mooring anchor chain sample of marine engineering immersed in seawater , which improves the accuracy of the fatigue test of marine engineering mooring anchor chains.

Description

technical field [0001] The invention relates to a fatigue test device for anchor chains, in particular to a fatigue test device for simulating an ocean engineering mooring anchor chain subjected to alternating stress under complex sea conditions, and belongs to the technical field of ocean engineering mooring devices. Background technique [0002] With the continuous utilization and development of marine resources by humans, marine energy development devices such as marine mineral resource exploration and development projects, offshore tidal power stations, wave power stations, and thermal power stations have been continuously put into use to provide new energy for humans. These engineering structures anchored in the ocean are positioned in the sea through the marine engineering mooring anchor chain. Therefore, the marine engineering mooring anchor chain is an important outfitting piece related to the safety of marine engineering. Due to the long service life of marine engin...
