Problems solved by technology

[0007] The bracket of the second structure also has problems similar to those of the first structure, and even more serious, because the insulating fastener of the second bracket has one more flange than the first one, and one more bend. In this way, when die-casting The position of the wing plate is less accessible to the casting liquid, the pressure is smaller, the material density is thinner, and the strength is weaker. After assembly, this position is more likely to be broken and damaged, and it is more likely to cause the bracket to be fixed to the track. Failure, stability and firmness Worse, with greater safety hazards

Abstract

The invention discloses a subway third-rail insulating bracket. The subway third-rail insulating bracket comprises an insulating fastener (1), an insulating carrier frame (2) and a base (3), wherein the insulating bracket (2) comprises a top beam (2.1), a lower supporting plate (2.2) and an inclined arm (2.3); the rear end of the top beam (2.1) and the rear end of the lower supporting plate (2.2) are fixed on the front end surface of the inclined arm (2.3); the insulating fastener (1) is composed of a vertical plate (1.1) and an inclined supporting plate (1.2); the upper end surface of the vertical plate (1.1) is a lower inclined surface (1.3); the front end of the bottom surface of the top beam (2.1) is an upper inclined surface (2.4); the insulating fastener (1) is in threaded connection with the top beam (2.1) through a bolt (4) perpendicular to the upper inclined surface (2.4); and the lower supporting plate (2.2), the inclined arm (2.3), the top beam (2.1) and the insulating fastener (1) form a chamber for accommodating the upper part of a third rail (5). The bracket is good in stability and firmness, and can avoid potential safety hazards.

Description

technical field [0001] The invention relates to the field of urban traffic, in particular to a third-rail insulating support for a subway track. Background technique [0002] At present, most urban subways adopt the third-rail power receiving method, that is, an I-beam is laid in parallel outside the two rails as the third rail (contact rail), and the subway tram receives power from the third rail through the power receiving device. [0003] The third rail is suspended in the air, and the third rail is provided with a third rail insulating support for suspending and fixing the third rail every certain distance (such as 4.5 meters). [0004] In 2010, our company applied for an invention patent with the patent number CN201010190891.3 and the name of the insulation support for the third rail of the subway, such as figure 1 As shown, the support includes an insulating bracket 101, an insulating fastener 102 and a base 103 fixed on the track foundation; the insulating bracket 10...
