Abstract

The invention provides a rigid contact net grinding and polishing device which is used for automatically grinding and polishing a contact line and comprises a frame body, two pairs of guide wheels are arranged on the two sides of the upper end of the frame body, a positioning wheel is arranged below each pair of guide wheels, and clamping parts used for clamping a busbar are formed by the wheel faces of the guide wheels and the wheel faces of the positioning wheels; the lower end of the frame body is provided with at least one polishing wheel, the polishing wheels are parallel to rotating shafts of the guide wheels, the polishing wheels are connected with an output shaft of the motor, the polishing wheels polish contact lines at the lower end of the busbar, and the polishing wheels rotate to drive the frame body to move on the busbar. And compared with an original construction method, the rigid contact net grinding device can achieve automatic grinding, the construction difficulty is greatly reduced, safety is higher, and working efficiency is higher.

Description

technical field [0001] The invention relates to the technical processing field of urban rail power supply, in particular to a grinding and polishing device for a rigid catenary. Background technique [0002] Rigid catenary, as a low-clearance overhead catenary suspension form, was introduced from abroad to Guangzhou Metro Line 2 for the first time in 2003. Due to its simple structure, easy maintenance, and good performance in years of operation, It has been widely used in major cities in recent years. [0003] In actual operation, the rigid catenary often has poor elasticity in local sections, high wear rate of contact wire, and uneven wear. At the same time, there is also the problem of irregular wear of the carbon slide plate of the electric bus pantograph. The irregular wear of the carbon skateboard aggravates the uneven wear of the contact line, worsens the pantograph-catenary relationship, and has a serious impact on the safe operation of the subway. [0004] Contact ...
