Problems solved by technology

In 2012, the louvers of the air duct on the top of the track at Baogong Street Station of Shenyang Metro Line 1 fell off, causing the pantograph to touch the louvers when the train arrived at the station, resulting in a power outage of the catenary, which in turn led to the train suspension of the entire line for 2 hours

Embodiment Construction

[0008] Reconstruction of rail top air vents in subway stations, such as figure 1 As shown, the shutters of the tuyere are located on the lower side of the tuyere of the air duct on the top of the track and at the top of the catenary. According to the starting point of the station, the center line of the station and the end point of the station, the up and down track area can be divided into four identical areas. From the end point of uplink to the center line of the station, from the starting point of downlink to the center line of the station, and from the end point of downlink to the center line of the station, the twenty-four sets of rail top air outlets are divided into four exactly the same places, each with six groups, and the start point and end point of the station are close to the wind end, the center line of the station is the far wind end. There are 12 small units in the six groups, and the size of each small unit is the same, and the size is 1000mm×500mm.

Abstract

The invention relates to rail top air port modification for subway stations. According to the modification, air port louver windows are arranged on the lower sides of rail top air channel air ports and the upper ends of overhead line systems, an up and down rail running area is divided into four identical areas according to the station starting point, the station center line and the station terminal point, one of the four areas starts from the up starting point to the station center line, the subway rail top air channel air ports are located right above the overhead line systems of the rail running area, and the construction method needs to be reasonable and reliable due to the special position. Installing and debugging of the rail top air channel pull plate type air ports of the stations of double-layer island type structures are introduced in the article; compared with other installing modes, the installing mode of the pull plate type air ports has the advantages that installing is reliable, debugging is convenient and the safety is higher though the direct economic value is not obvious and is innovative for installing of rail top air channel air ports.

Description

technical field [0001] The invention relates to a reconstruction of a rail top air outlet, in particular to a rail top air outlet reconstruction of a subway station. Background technique [0002] The air outlets of the track top air ducts of Shenyang Metro Lines 1 and 2 are directly fixed below the civil engineering reserved air outlets with shutters. The tuyere louver is on the lower side of the air duct tuyere on the top of the rail and the upper end of the contact net. In 2012, the louvers of the rail top air channel at Baogong Street Station of Shenyang Metro Line 1 fell off, causing the pantograph to touch the louvers when the train arrived at the station, resulting in a power outage of the catenary, which in turn led to a 2-hour train suspension on the entire line. The shutters of the air vents at Baogong Street Station are in accordance with figure 1 in the way to fix it. Contents of the invention [0003] The object of the present invention is to provide a kin...
