Description
Technical Field
[0001] The utility model relates to the field of subway fixed catenary grinding, in particular to a catenary grinding system with a transverse reciprocating grinding function. Background Technique
[0002] In recent years, abnormal wear of catenaries has occurred in subways across the country. Due to the lack of experience in rectification, it is rather difficult for operation managers to handle such problems. The abnormal wear of the catenary and the accelerated wear rate of the pantograph carbon skate will have a serious impact on operation safety. Therefore, it is of great significance to grind and dispose of the abnormal wear of the catenary and pantograph. The main reasons for the abnormal wear of the catenary include: First, one of the contact wire pull-out value, height, and mid-span contact wire does not meet the specification requirements, which leads to large force fluctuations when the pantograph passes through the contact wire, causing local abnormal wear of the catenary; Second, the contact wire surface is greatly skewed, which affects the position of the positioning clamp, resulting in poor contact between the pantograph and the catenary, causing local abnormal wear of the catenary; Third, the suspension string is not fully stressed, resulting in bow scraping, causing local abnormal wear of the catenary; In addition, affected by environmental factors such as wind, temperature, and humidity, the surface characteristics such as the friction force of the contact wire change, resulting in local abnormal wear of the catenary. For local abnormal wear of the catenary, the contact wire will be damaged to a certain extent, and the phenomenon is that the contact wire will show metal drawing, but the serious consequences caused by it will not appear immediately. When this metal drawing falls off or contacts other subway electrical equipment, serious short-circuit accidents and secondary hazards will occur. Therefore, it is very important to remove the drawing of the contact wire, avoid serious secondary accidents of bow scraping, and regularly grind the contact wire.
[0003] In the existing contact wire grinding device, the grinding wheel mainly grinds along the contact wire in the forward or reverse direction. This grinding method has a certain effect, but due to the lack of transverse grinding force during the grinding process, the grinding effect on the tiny drawing at the edge of the contact wire is not good. Therefore, there is an urgent need for a catenary grinding system with a transverse reciprocating grinding function to improve the grinding effect of the catenary. Summary of the Invention
