Abstract

The invention discloses a detection device for a tensile test of a bridge steel strand, a U-shaped box is welded and mounted at the bottom of a top plate, a hydraulic rod and a U-shaped placement box are welded and mounted at the top of the top plate, the U-shaped placement box covers the hydraulic rod, the number of top transverse moving grooves of the top plate is two, the top transverse moving grooves are respectively located at two sides of the U-shaped placement box, transverse moving blocks are slidably mounted in the two transverse moving grooves, fixing blocks are welded to the tops of the transverse moving blocks, a rotary clamping and positioning mechanism is arranged in the position, on the top side of the fixing blocks, of the rack, a transmission type circulating downward pressing mechanism is arranged in the U-shaped placement box, and a mechanical opening type pushing mechanism is arranged in the U-shaped box. According to the detection device, the steel strand can be powerfully clamped, the steel strand can be rapidly stretched, and a certain position of the fixed steel strand can be circularly beaten, so that relatively strict steel strand detection data can be obtained, and manual detection of workers is not needed.

Description

technical field

[0001] The invention relates to the technical field of bridge steel strands, in particular to a detection device for tensile testing of bridge steel strands. Background technique

[0002] Steel strand is a steel product composed of multiple steel wires, which can be divided into prestressed steel strand, unbonded steel strand, galvanized steel strand, etc. Its carbon steel surface can be added with galvanized layer, zinc-aluminum alloy layer, aluminum-clad layer, copper-plated layer, epoxy resin coating, etc. according to needs. Steel strands are mostly used in bridge construction, and with the development of the times, steel strands Production companies have sprung up all over the country.

[0003] However, the existing steel strand manufacturing companies cannot perform good strength and elongation tests on the steel strands after the production of the steel strands is completed. Ensuring the rigor of the data may lead to some serious incidents during the...
