A kind of early warning double grid detection railway fence of railway crossing

Abstract

The invention discloses an early-warning double-power-grid detection railway fence for a railway crossing. The early-warning double-power-grid detection railway fence structurally comprises an anti-climbing-over top fence, a fixing bottom frame, jointing insert openings, an inner grid and fixing feet; the anti-climbing-over top fence is horizontally placed at the top of the fixing bottom frame, and the bottom of the anti-climbing-over top fence is fixed in a welded mode; the two jointing insert openings are formed in the left side of the fixing bottom frame; and the inner grid is tightly nested in an inner groove of the fixing bottom groove. To sum up, after the early-warning double-power-grid detection railway fence is improved, vibration and airflow generated by high-speed traveling of atrain serve as detection conditions, early warning is conducted on the position, close to the railway crossing, of the early-warning double-power-grid detection railway fence to warn surrounding personnel not to approach in time, meanwhile a communication pull rope for triggering of the early-warning double-power-grid detection railway fence serves as a detection line to ensure the that after being damaged and broken off, the fence can be detected in time to be maintained.

Description

technical field [0001] The invention relates to a railroad fence for railway crossing detection, in particular to a railroad fence for early warning double grid detection of railway crossings.
