Line rail frog wear inspection ruler

Abstract

The invention discloses a line rail frog wear inspection ruler, which relates to the technical field of line rail inspection. The invention includes a ruler plate, a control box, a first adjustment frame and a second adjustment frame, the middle part of the ruler plate is fixedly fitted with a second adjustment frame, and the ruler plates on both sides of the second adjustment frame are symmetrically slidingly fitted with a first adjustment frame A control box is fixedly connected to one end surface of the ruler plate; wherein, a first measuring frame and a second measuring frame are respectively fixedly fitted on the bottom surfaces of the two first adjusting frames, and a first measuring frame is arranged on the second adjusting frame. ruler; the middle part of the rear side of the ruler plate is fixedly engaged with iron bars along the direction in which the ruler plate extends. The present invention uses the first electromagnetic column, the control box, the second electromagnetic column, the iron bar, the permanent magnet column, the first abutting column, the placement groove, the first rotating sleeve, the second rotating sleeve, the rotating column, the second abutting column and quantitative The setting of the hole makes the adjustment process of the device measurement more efficient and convenient, the effect of folding and storage is good, and the positioning of the measuring ruler at one-third of the rail surface is more efficient and accurate.

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.
