Description

Technical Field

[0001] The utility model relates to the technical field of electrified railway component machinery, in particular to a multi-dimensional deviation correction device for a catenary compensation pulley block. Background Art

[0002] The catenary is a special form of transmission line that is erected in a "zigzag" shape above the rails along the railway line to supply power to electric locomotives. The catenary compensation device mainly consists of a compensation pulley block, a counterweight, and a counterweight restraint frame. One end of it is connected to an anchor post through a double-loop rod and a lower anchor angle steel, and the other end is connected in series with the catenary wire through a clamp. The counterweight moves up and down to keep the wire tension constant.

[0003] Compensation pulley devices are widely used in electrified railways in China. It mainly consists of a fixed pulley, a movable pulley, a compensation wire, etc. Different combinations of fixed pulleys and movable pulleys are used to achieve the required tension of the catenary.

[0004] At present, one end of the fixed pulley of the compensation pulley block in the market is rigidly connected to components such as a double-loop rod through a bolt pin and an anchor post. One end of the movable pulley is connected to the wire of the non-working support. There is a certain angle and inconsistent force directions between the non-working support and the working support (in the same direction as the rail direction). Moreover, the wires and components of both meet and are fixed at the conversion post position, and are erected and connected at multiple angles, resulting in the working state of the compensation pulley block being superimposed with multi-directional forces and torques. It is not easy to adjust in real time after skewing. On the other hand, when the temperature changes, the wire expands and contracts, and the counterweight moves up and down. Due to the cumulative installation process, component matching errors, and the influence of the restraint frame, the compensation pulley block is skewed and not perpendicular to the ground, and the compensation wire installed with the counterweight cannot be completely vertical upward.

[0005] The skewed operation of the compensation pulley block causes the compensation wire to rub against the side wall of the fixed pulley groove. The superimposed forces and torques also exacerbate the wear degree of the side wall of the fixed pulley groove and even cause out-of-groove jamming, resulting in insufficient tension of the catenary wire and triggering accidents. For this reason, we propose a multi-dimensional deviation correction device for a catenary compensation pulley block. Content of the Utility Model
