Line steel rail frog abrasion inspection ruler

Abstract

The invention discloses a line steel rail frog abrasion inspection ruler, and relates to the technical field of line steel rail inspection. The ruler comprises a ruler plate, a control box, a first adjusting frame and a second adjusting frame, the middle of the ruler plate is fixedly sleeved with the second adjusting frame, and the parts, on the two sides of the second adjusting frame, of the ruler plate are symmetrically and slidably matched with the first adjusting frame; one end surface of the ruler plate is fixedly connected with a control box, wherein a first measuring frame and a secondmeasuring frame are respectively and fixedly arranged on the bottom surfaces of the two first adjusting frames in a matched manner, and a first measuring ruler is arranged on the second adjusting frame in a matched manner; an iron bar is fixedly clamped in the middle of the rear side face of the ruler plate in the extending direction of the ruler plate. Through the arrangement of the first electromagnetic column, the control box, the second electromagnetic column, the iron bar, the permanent magnetic column, the first abutting column, the placing groove, the first rotating sleeve, the second rotating sleeve, the rotating column, the second abutting column and the quantitative hole, the device is more efficient and convenient in measurement adjustment process, good in folding and storage effect and more efficient and accurate in positioning of the measuring ruler at the one-third position of the rail surface.

Description

technical field [0001] The invention belongs to the technical field of line rail inspection, in particular to a line rail frog wear inspection ruler, which is mainly used for checking the wear degree of line rail frogs. Background technique [0002] Frog refers to the equipment that makes the wheel cross the other rail from one rail. It is composed of fork core, wing rail and connecting parts. In the process, there will be a certain degree of wear and tear. In the case of severe wear, it will affect the normal use of the frog. For this reason, railway maintenance personnel will regularly check the wear of the frog with an inspection ruler. At present, the existing frog wear inspection ruler In the process of use, the measuring claws need to be moved frequently and measured after being positioned by the locking bolts. However, because there are many items for frog wear inspection and the measurement points are wide, it is troublesome to adjust the measuring claws so frequentl...

Problems solved by technology

[0004] The object of the present invention is to provide a line rail frog wear inspection scale, through the adsorption fit between the first electromagnetic column and the iron bar, after moving the measuring claw, the positioning after the movement can be realized without manually tightening the bolts, through the second The same-sex repulsion between the electromagnetic column and the permanent magnetic column can realize the fixing of the first measuring rod by the first contact column, through the rotatable connection between the first measuring frame and the second measuring frame and the first adjusting frame and the placement slot The setting of the first measuring frame, the second measuring frame and the first measuring ruler can be folded and stored. Through the setting of the second column and the quantitative hole, the advance adjustment of the measuring ruler at one-third of the rail surface is more accurate. It solves the problems that the existing frog wear inspection ruler needs to be frequently adjusted when the measuring claw is used, the operation is troublesome and time-consuming, the inspection ruler itself cannot be folded and stored, and the manual adjustment of the measuring ruler at one-third of the rail surface causes increased errors.
