Problems solved by technology

However, this material still has insufficient impact resistance, is easy to fall off, and also has intermittent contact with the contact line, which limits its application.
[0003] During the actual use of the current carbon skateboard, the carbon strip and the contact wire often spark, and then there is a problem of high temperature ablation of the contact wire or carbon strip, which leads to unstable flow between the contact wire and the train, affecting driving safety

Embodiment Construction

[0021] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0022] A keyboard type pantograph slide, such as Figure 1-Figure 7 As shown, the skateboard is composed of a bow angle 1, a base 2, an elastic conductive component 3 and fasteners. The bow angle 1 is a profile with the structure of the cavity 7 in the bow angle, that is, the bow angle 1 is a rectangular tube structure with a certain wall thickness in section, and the bow angle 1 has a straight section 5 of the bow angle and a curved section 4 of the bow angle. There is a smooth transition between the angle straight section 5 and the bow angle bending section 4. On the bow angle straight section 5 of the bow angle 2, a transparent bow angle counterbore 6 is processed, and the bow angle fastener 8 can be used to fasten ...

Abstract

The invention discloses a keyboard type pantograph slide plate which comprises a pantograph horn, a base and elastic conducting assemblies. After the keyboard type pantograph slide plate makes contact with a contact line, due to the fact that the multiple rows of elastic conducting assemblies have elasticity and are arranged on the base at intervals in a staggered mode, the contact line always makes contact with contact blocks which is directly pressed by the bottom of the contact lines or pressed by the side face of the contact line, the contact line is kept in contact with the contact blocks of the elastic conducting assemblies all the time, and stable current collection between the contact line and a vehicle is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mechanical devices and transportation, and in particular relates to a keyboard-type pantograph slide. Background technique [0002] With the rapid development of the national economy, the scale of the city continues to expand, the population of the city center and the number of vehicles increase sharply, and the problem of traffic congestion is becoming more and more serious. Transportation methods such as public transport and private cars are far from meeting people's requirements for fast and punctual travel. The way of traveling by rail transit has been widely welcomed by people. Rail transit has the characteristics of large transport volume, fast speed, high punctuality, safety and reliability, energy saving and environmental protection. At present, cities with serious congestion have started or planned rail transit projects to alleviate the problem of traffic difficulties. At present, rail transit...
