The invention discloses a four-point bending test device for
pipe full-size evaluation, and relates to the technical field of testing device of
engineering pipes and supporting components. A device of the prior art cannot meet
engineering requirements in the aspects of test precision,
load capacity, test safety and the like. For overcoming the shortcomings of the prior art, the technical scheme provided by the invention comprises that the four-point bending test device for
pipe full-size evaluation includes an electric lifter, a force measuring sensor, a clamp
assembly, a guyed displacement sensor, a magnetic suction block for connecting the displacement sensor and a sample, a lifting bridge, and lifting lugs for connecting the lifting bridge and a full-size evaluation test
machine. With a ball head
connection form of the clamp
assembly, the test is closer to on-service real working conditions of a
pipe, the electric lifter is used as a bending load loading mechanism, the supporting load is large, safe and stable, and loaded data are accurate; the displacement sensor replaces a strain gage acquisition
system, so the efficiency is improved, and the financial resources are saved; and the four-point bending test device can meet the needs of
engineering technology.
