Problems solved by technology

[0003] There are deficiencies in the existing rail top derusting device for railway track maintenance: when the existing rail top derusting device derusts, the fastening assembly below it contacts the lower surface of the rail, thereby derusting the derusting device. The positioning is fixed. As the rust removal progresses, the contact point between the fastening component and the lower surface of the rail will be worn, and the wear will cause the fastening component to loosen, thereby reducing the tightness of the positioning and fixing, resulting in the fastening component not being able to achieve its intended value. Some functions prevent the derusting components above from completing the derusting operation normally, which affects the derusting effect

Abstract

The invention belongs to the technical field of railway maintenance, in particular to a rail top derusting device for railway track maintenance. When derusting the existing rail top derusting device, the fastening component below it is in contact with the lower surface of the rail, thereby Position and fix the derusting device. As the derusting proceeds, the contact point between the fastening component and the lower surface of the rail will be worn, thereby reducing the tightness of the positioning and fixing and affecting the derusting effect. The following solutions are proposed, including the mounting frame. The present invention is provided with a spring rod, an upper adjusting plate, a lower adjusting plate and an ejecting block, and when the lower surface of the rail is fixed, the ejecting block on the upper adjusting plate is pushed out by adjusting the hydraulic cylinder to contact with the lower surface of the rail, and then The spring rod is squeezed, and the spring rod is compressed to its elastic critical point. During the rust removal process, the ejector block is worn, and its thickness is slightly thinner. The elastic potential energy of the spring rod drives the upper adjustment plate to move and fine-tune, so that the ejector block and the rail The lower surface is again in close contact.

Description

technical field [0001] The invention relates to the technical field of railway maintenance, in particular to a rail top derusting device for railway track maintenance. Background technique [0002] The railway is a track line for trains and other means of transportation. During the long-term use of the railway, the top of the rail will be corroded. This requires the use of a derusting device to remove the rust on the top of the rail, so as to ensure that the rail can be used normally. [0003] There are deficiencies in the existing rail top derusting device for railway track maintenance: when the existing rail top derusting device derusts, the fastening assembly below it contacts the lower surface of the rail, thereby derusting the derusting device. The positioning is fixed. As the rust removal progresses, the contact point between the fastening component and the lower surface of the rail will be worn, and the wear will cause the fastening component to loosen, thereby reduci...
