Cutting machine for steel strands in anchor recesses of railway box girder

Abstract

The invention relates to a cutting machine for steel strands in anchor recesses of a railway box girder, and belongs to the technical field of cutting devices. The cutting machine comprises a plate frame mechanism, an up-and-down moving mechanism, a left-and-right moving mechanism, a front-and-back moving mechanism and a cutting mechanism, wherein the cutting mechanism comprises a cutting motor and a cutting blade, and the cutting blade is installed at the output end of the cutting motor; the cutting mechanism is fixedly connected with the front-and-back moving mechanism, a front-and-back moving pair is formed between the front-and-back moving mechanism and the left-and-right moving mechanism, and a left-and-right moving pair and an up-and-down moving pair are formed between the left-and-right moving mechanism and the up-and-down moving mechanism respectively; and the plate frame mechanism can be connected with a mechanical arm. The cutting machine can accurately and effectively cut the steel strands in anchor recesses, and the labor intensity of cutting the steel strands in the anchor recesses is greatly reduced.

Description

technical field [0001] The invention relates to a machine for cutting steel strands in anchor holes on the end faces of railway prefabricated box girders, and belongs to the technical field of cutting devices. Background technique [0002] my country's railway construction accounts for a large proportion of bridges, most of which are simply supported beam bridges with standard spans. The construction of these bridges requires the manufacture of a large number of prefabricated box girders for railways. In the manufacture of railway prefabricated box girders, after demoulding, concrete pouring needs to go through processes such as tensioning, grouting, cutting of steel strands, chiseling and sealing of anchor hole holes, among which cutting of anchor steel strands requires mechanical cutting. In the current cutting process of anchor hole steel strands, most of them are cut by manual hand-held cutting machines, which have the disadvantages of low work efficiency, high labor in...

AI Technical Summary

Problems solved by technology

In the current cutting process of anchor hole steel strands, most of them are cut by manual hand-held cutting machines, which have the disadvantages of low work efficiency, high labor intensity, and high safety risks.

It is difficult to adapt to the running displacement of the small space in the anchor hole by using a general mechanical cutting device, so the steel strands in the anchor hole cannot be cut accurately and efficiently
