Embodiment Construction

[0013] Such as figure 1 As shown, the line switch body 1 is an aluminum alloy body with a groove body, and the two ends of the aluminum alloy body are embedded in the groove-shaped body with aluminum alloy plates 9, and then two rivets 7 are used to connect the aluminum alloy body of the groove body and the aluminum alloy body. The plates 9 are riveted together. There are installation holes on the aluminum alloy plate 9 corresponding to the holes at the two ends of the switch body 1 respectively, and the distance between the holes at the two ends of the switch body 1 is 1960mm. The lag bolt 2 passes through the hole of the switch body 1, and the positioning clamp 8 and the washer 5 are installed under it, and the washer 5, the spring washer 4, the nut 3 and the cotter pin 6 are installed on the top. The positioning wire clamp 8 plays a positioning role, and the positioning wire clamp 8 is connected with the lag bolt 2 and can rotate around the lag bolt 2. The upper and lower ...

Abstract

The invention belongs to a crossover applied to two intersecting contact wires in an electrified railway contact system, which is characterized in that aluminum alloy plates (9) are embedded at two ends of a groove-shaped crossover body (1) and riveted together by rivets (7). The crossover has light weight and large anti-bending section modulus, low possibility of bending and deformation under force and no resistance against contact wire movement, and the phenomena like pantograph scratch and pantograph drilling which influence transportation safety are avoided.

Description

technical field [0001] The invention belongs to a line switch applied at two intersecting contact lines of an electrified railway catenary. Background technique [0002] At present, the turnout bodies used in my country's electrified railway turnouts are basically made of steel pipes or aluminum tubes. Due to the long body of the turnout and poor bending resistance, the body of the turnout is easily bent and deformed after being stressed, resulting in two contact lines. The installation position changes, the movement of the contact wire is blocked, and even the two contact wires cannot be raised at the same time, and the pantograph cannot pass smoothly. In severe cases, there is a danger of drilling the bow and even scratching the pantograph, which brings hidden dangers to the normal operation of the railway. Contents of the invention [0003] In order to overcome the poor bending and deformation resistance of the above-mentioned line switch body, the present invention prov...
