Description

Technical Field

[0001] The invention discloses a viscous stabilizer for an electrified railway contact network weight, and belongs to the fields of fluid and machinery. Background Art

[0002] At present, on electrified railways, the gravity of the weight is generally used to achieve the tensioning of the contact line and the load-bearing cables, prevent the contact line and the load-bearing cables from excessively falling and affecting the normal operation of the train. At the same time, in order to prevent the weight from rotating and swinging under the action of wind, a fixed weight limiting duct is used to limit it. In order to prevent the formation of excessive vertical viscosity on the surface of the weight limiting duct and affect the tensioning force of the weight's gravity on the contact line and the load-bearing cables, a certain radial distance is set between the weight limiting duct and the weight limiting device, so that under normal conditions, the weight limiting duct and the weight limiting device are in a non-contact state. Since there is a certain radial distance between the sinker weight limiting tube and the sinker weight limiting device, under the action of strong wind force, the sinker weight will drive the sinker weight limiting device to form a radial impact on the sinker weight limiting tube, and this impact force will react on the sinker weight and the sinker weight rod. On the one hand, it will affect the stability of the tensioning force of the contact line and the load-bearing cable. On the other hand, it will also have a certain impact on the service life of the sinker weight rod. Summary of the invention

[0003] The present invention proposes a viscous stabilizer for an electrified railway contact network weight. The viscous fluid in the viscous stabilizer produces a damping effect when the moving and static laminations in the viscous stabilizer move relative to each other, thereby consuming the swing energy of the weight, reducing the swing amplitude and frequency of the weight, and reducing the impact force of the weight when it swings, thereby effectively improving the working stability of the weight tensioning system and ensuring the normal operation of the contact line and the load-bearing cable.
