Electronic railway contact net stand column passing device

Abstract

The invention discloses an electrified railway catenary column crossing device, which comprises a main beam, a left beam and a right beam connected to both sides of the main beam, and the main beam is divided into an upper main beam, a lower main beam and a telescopic connecting main beam sleeve, and the bottom end of the upper main beam or the top of the lower main beam is sleeved and connected with a main beam telescopic sleeve; the left side beam includes a left upper side beam, a left lower side beam and a left telescopic sleeve, and the left upper side beam The bottom end or the top of the left lower side beam is fitted with a left telescopic sleeve, the right side beam includes a right upper side beam, a right lower side beam and a right telescopic sleeve, and the bottom end of the right upper side beam or the top of the right lower side beam The upper sleeve is connected with a right telescopic sleeve. The present invention utilizes the expansion and contraction effect of the telescopic sleeve, and when the telescopic sleeve is retracted, a gap is formed to realize the avoidance of the column, and the main beam, the left beam and the right beam form gaps in sequence to realize the avoidance, and when any beam body forms When avoiding the gap, the other two beams are in a connected load-bearing state, which does not affect the safety of the overall mechanical equipment.

Description

technical field [0001] The invention relates to the field of electrified railways, in particular to an electrified railway catenary column crossing device. Background technique [0002] The catenary column of the electrified railway plays an important role in supporting the power network, and a column is erected every tens of meters on both sides of the electrified railway. However, the column has a very large impact on the operation of some mechanical construction and testing equipment, resulting in the inability of the mechanical equipment to work continuously. When a construction machine encounters a column, it must take back the equipment extending outside the line, avoiding the column and then stretching out to work, which greatly affects the work efficiency. See figure 1 , a schematic diagram of the relationship between the column and the main beam of the mechanical arm; when the main beam 1 moves to the right, it cannot pass due to the blocking of the column 4.
