Abstract

The invention discloses a guardrail height adjustment device for a catenary maintenance vehicle penetrating platform. The guardrail height adjustment device comprises a plurality of height adjustmentsections which are sequentially arranged from left to right. The height adjustment sections comprise first supporting piece, second supporting pieces with length being shorter than the first supporting pieces, third supporting pieces and first bases arranged on the catenary maintenance vehicle penetrating platform. The upper ends of the first supporting pieces are movably connected to a guardrailof the catenary maintenance vehicle left and right, and the lower ends of the first supporting pieces are hinged to the catenary maintenance vehicle penetrating platform. The upper ends of the secondsupporting pieces are hinged to the middle of the first supporting pieces, and the lower ends of the second supporting pieces are hinged to the third supporting pieces. The third supporting pieces aremovably connected to the first bases up and down. The guardrail height adjustment device can realize independent adjustment that only the height of a single guardrail is changed and avoids the problem that each guardrail cannot be adjusted to the same height due to the following actions of other height adjustment sections when one height adjustment section is adjusted.

Description

technical field [0001] The invention relates to the technical field of catenary overhaul, in particular to a guardrail height-adjusting device for a penetrating platform of a catenary overhaul vehicle. Background technique [0002] The catenary is the main frame of the railway electrification project, and it is a special form of transmission line erected along the railway line to supply power to the electric locomotive. [0003] When encountering severe weather such as strong winds, thunderstorms or human sabotage, the catenary will be damaged to varying degrees, such as breakdown of insulators, breakage of pillars, broken wires, damage to pantograph and catenary, or some parts falling off. When the catenary is damaged to a large extent, it will affect the normal operation of the electric locomotive, and even cause serious safety accidents. Therefore, it is necessary to regularly overhaul the catenary to avoid the risk of serious damage to the catenary affecting the normal ...
