specific Embodiment

[0039] Such as Figure 1-2 As shown, a special pantograph includes a base 7 and a cylinder 6 arranged in the base 7. The cylinder 6 is connected to the spring 3 through a wire rope 11, and the spring 3 is connected to the bow arm 8 to form a lifting bow system. The bow head includes slide plates 1 and 10, a bow head insulator 8 and an elastic buffer device. The double bows are flexibly connected by the bow connector 9 made of insulating material.

[0040] In the pantograph structure of the present invention, when the pantograph is raised, the air cylinder 6 intakes air, the cylinder piston moves vertically, the piston rod drives the wire rope 11 to pull the bow raising spring 6, the spring 6 elongates and deforms, and acts on the bow arm 4, the bow arm 4 is pulled up to raise the pantograph to the working height. The positive sliding plate 1 and the negative sliding plate 10 are respectively in contact with the positive and negative wires of the catenary 12 to receive electr...

Abstract

The invention discloses a pantograph for road heavy trucks, which includes a bow arm, the upper end of the bow arm is connected with a bow head insulator, a slide plate is connected with the bow head insulator, the lower end of the bow arm is installed on the bottom box, and the bow head insulator is connected with the bow head insulator. A balance bar is connected between the bottom boxes; the bow arm is a single bow arm structure, and the balance bar is hidden in the bow arm. The bow-raising system includes a bow-raising cylinder, a fixed pulley, a wire rope and a bow-raising spring. The double-bow insulated connecting piece between the positive sliding plate and the negative sliding plate is a flexible connecting piece. It has the characteristics of long service life, high safety, and reliable strength. It solves the problem that electric heavy-duty trucks receive electricity from the road catenary to drive the vehicle stably, ensuring safe, reliable and normal operation of electric trucks.

Description

technical field [0001] The invention relates to a high-speed heavy-duty truck equipment for electrified highway with centralized power supply by a power grid, in particular to a pantograph for a heavy-duty highway truck. Background technique [0002] At present, the demand for green development continues to promote the process of vehicle electrification. Driven by national policies, pure electric vehicles, especially pure electric light trucks, passenger cars and buses, have been applied on a large scale in areas such as regional logistics and transportation, personal travel, and public transportation. Long-distance heavy-duty new energy trucks have also received attention. How truck pantographs get power from the road grid is the key technology that combines the efficiency of electrified railways with the flexibility of truck transportation. [0003] Pantographs are mainly used in electric locomotives or trains. The technical problems to be solved when the existing pantogr...
