Embodiment Construction

[0030] The present invention will be described in detail below in combination with specific embodiments.

[0031] The electrified high-speed railway catenary design system is designed for constant tension compensation. An anchoring device for compensation is installed at the end of each anchor section. At present, the ratchet compensation device is used in the design. It has a compact structure, high compensation efficiency and has a braking function. The product is more mature.

[0032] The adaptability of electrified railway catenary to train speed also depends on the tension and power supply capacity of the conductor. The higher the speed, the greater the tension. When the tension of the conductor is greater than 30kN, the terminal anchoring device does not meet the technical requirements, so a heavy-duty cable must be designed. Type ratchet compensation device.

[0033] In the busy route of cargo transportation, in order to improve the efficiency of transportation capacit...

Abstract

The invention relates to a double-winding-rope heavy load vertical tooth ratchet wheel compensation device used for overhead line system compensation anchorage. The device comprises a vertical tooth type bisymmetric wide ratchet wheel body, the two sides of the vertical tooth type bisymmetric wide ratchet wheel body are fixed to whole connecting crank arms, the whole connecting crank arms on the two sides are fixed to L-shaped ratchet wheel shaft supporting frames, and the L-shaped ratchet wheel shaft supporting frames are connected with a ratchet wheel fixing support through a stainless steelratchet wheel shaft. The ratchet wheel body of the device is of a double-set end face vertical tooth structure, and a lengthened toothed plate is adopted as a brake plate and can be effectively clamped in teeth when a fault occurs and a line is broken; and output and input compensation rope sheave grooves are symmetrically formed, double steel wire ropes are output and input, the anchoring forceof a overhead line system terminal is reduced by 1 / 2 in the position of a balancing wheel, force distributed on the wheel body is evenly distributed, the wheel body adopts symmetric wide wings, stability and reliability are high, and an instability phenomenon is avoided.

Description

technical field [0001] The invention relates to the technical field of electrified railway catenary, in particular to a double rope heavy-duty vertical tooth ratchet compensation device for catenary compensation anchoring. Background technique [0002] With the vigorous development of high-speed railways, the technology of 350 kilometers per hour high-speed railways and even ultra-high-speed railways has been fully implemented. As the power supply unit of electric locomotives, the tension system of the wires has been continuously improved, from the original 5-ton system to 6-ton system or even higher. High, the bearing capacity of the matching terminal force anchorage device of the catenary also increases accordingly. [0003] At the anchorage point of the rigid-flexible transition terminal of the movable catenary, the contact line and the catenary cable are merged and anchored, and the output tension is doubled. Ordinary ratchets and compensating devices cannot meet the re...
