Embodiment Construction

[0028] The present invention will be further described below in conjunction with drawings and embodiments.

[0029] Embodiment 1 of the present invention, see figure 1 and Figure 4 . The casing 5 is set in the jacking pipe 8 and can rotate freely in the jacking pipe 8 , and the two ends of the casing 5 are respectively fixedly equipped with supports 4 . Skateboard 1 is designed as a single slideboard, and the width of slideboard 1 is at least twice the width of each slideboard in the pantograph head of double slideboards. The cross section of slideboard 1 is streamlined and designed with equal thickness. Limiting holes 6 are respectively provided at both ends, and "U"-shaped springs 3 are provided at both ends of the slide plate 1. One end of each "U"-shaped spring 3 is fixedly connected to the slide plate 1, and the other end is fixed to the sleeve 5. The support 4 is fixedly connected, and the central axis of the two "U"-shaped springs 3 is perpendicular to the running d...

Abstract

The invention discloses a direct-connection-type high-speed pantograph head which comprises a sliding plate (1), two pantograph horns (2), two springs (3) or (31) and two balance supports (4). The two ends of the sliding plate (1) are provided with limiting holes (6) respectively. The two pantograph horns (2) penetrate through the limiting holes (6) respectively. The two ends of the sliding plate (1) are connected with the balance supports (4) through the leaf springs. According to the direct-connection-type high-speed pantograph head, the balance supports are directly connected with the sliding plate through the simple leaf springs, the structure is simple, the size is small, the weight is low, and the aerodynamic characteristics are greatly improved.

Description

technical field [0001] The invention relates to a high-speed pantograph bow head, in particular to a streamlined high-speed pantograph bow head. Background technique [0002] The pantograph is the equipment used by the catenary to supply power to the EMU or electric locomotive. Since the EMU or electric locomotive is in contact with the catenary in motion, the requirements for the dynamic characteristics of the pantograph are very high. The bow head is the key part of the pantograph. The requirements of the pantograph for the bow head are simple structure, light weight, small size and good aerodynamic characteristics. At present, there are many kinds of high-speed pantographs in the world, and there are also many kinds of high-speed pantograph heads. However, the cross-section of the pantograph slide is not streamlined, at most it is diamond-shaped; the spring suspension structure supporting the pantograph slide does not have streamlined features; at present, the spring su...
