Problems solved by technology

A disadvantage of the four-bar linkage structure is that the pantograph cannot guarantee vertical lifting during the lifting process, resulting in the tilt of the pantograph bow head; the tilt of the pantograph bow head directly affects the contact between the carbon slide plate and the catenary, resulting in contact The phenomenon of uneven force, once the contact force is insufficient, it will easily cause the phenomenon of pantograph off-grid, forming arcing or insufficient carrying capacity, and in serious cases, the train will be shut down due to power failure; Carbon Skateboard Lifespan

Embodiment Construction

[0019] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0020] As shown in the figure, the present invention includes a base 1, a middle carriage 4 arranged in parallel above the base, a lower arm 2 and a support arm 5 respectively hinged between the two ends of the middle carriage and the base, and an upper arm hinged to the middle carriage. 3. Wherein, the two ends of the support arm are hingedly connected to the intermediate carriage and the base through ear sockets 10 respectively.

[0021] The lower arm and the support arm are arranged parallel to each other, the top end of the upper arm and the bottom end of the lower arm are hinged on the same end of the middle carriage and the upper arm and the lower arm are mutually axisymmetric with respect to the middle carriage; th...

Abstract

The invention belongs to the technical field of mechanical devices and traffic power transmission and particularly relates to a novel umbrella-shaped vertical-lifting pantograph body. The novel umbrella-shaped vertical-lifting pantograph body comprises a base, a lower arm, an upper arm, a middle slide rack, a support arm and an air cylinder. The pantograph body has the advantages that the pantograph body adopts the umbrella-shaped structure, and vertical lifting of a pantograph head can be guaranteed; the lower arm drives a traction part to drive a sector support plate through a transmission chain, and the positive pressure between the pantograph head and an overhead line system can be kept unchanged when the pantograph head works at optional working heights.

Description

technical field [0001] The invention belongs to the technical field of mechanical devices and rail transit power transmission, and in particular relates to a novel umbrella-shaped vertical lifting pantograph bow. Background technique [0002] The pantograph is the electrical equipment used by the electric traction locomotive to obtain electric energy from the catenary, and is installed on the roof of the locomotive or motor car. Pantographs can be divided into single-arm bows and double-arm bows, and their structures are composed of slide plates, upper frames, lower arm rods (lower frames for double-arm bows), underframes, bow springs, transmission cylinders, supporting insulators and other components. composition. Diamond pantographs, also known as diamond pantographs, were very common in the past, but they were gradually eliminated due to higher maintenance costs and the tendency to break the catenary when a fault occurs. [0003] In recent years, single-arm bows are mos...
