Detection scale of relative height difference of upper slope of railway turnout base plate and upper surface of bedplate

Abstract

The invention discloses a detection scale of relative height difference of an upper slope of a railway turnout base plate and an upper surface of a bedplate, which is composed of a base, a main scale, a vernier frame, a cross rod and a scale base, wherein the bottom surface of the base is a slope of which the gradient and the slant are coincident with the gradient and the slant of the base plate; the main scale is vertically fixed on the upper end surface of the base; the vernier frame is sheathed on the main scale to slide up and down along the main scale; the upper part of the vernier frame is a vernier, and the lower part is provided with a horizontal through hole; the cross rod is horizontally inserted in the horizontal through hole to slide left and right; and the scale base is fixed on the right end of the cross rod, and the front end surface of the scale base is provided with a measure meter holder. The detection scale of the invention has simple structure, flexible operation, accurate measurement and favorable adaptability, and can detect the relative height difference of all railway turnout base plates with the slopes and the bedplate as well as detect the slope manufacturing error situation.

Description

Technical field [0001] The invention relates to a detection ruler for the relative height difference between the inclined surface of a railway switch backing plate and the upper surface of the platform plate. Background technique [0002] In the high-speed passenger-dedicated turnout switch part, due to the need for repulsion and close adhesion between the basic rail and the tip rail, the rail under the rail adopts a backing plate with a sliding bed platen, and the 1:40 slope of the backing plate is opposite to the surface of the platen. The height difference will directly affect the relative position of the basic rail and the switch rail in the height direction and whether the railway laying can meet the needs of line operation. At present, for the detection of the relative height difference between the inclined surface of the backing plate and the surface of the platen at 1:40, the ordinary depth gauge is used for measurement. Due to the small contact surface of the ordinary de...

Problems solved by technology

At present, for the detection of the relative height difference between the 1:40 slope of the backing plate and the upper surface of the platen, ordinary depth gauges are used for measurement. Due to the small contact surface between the ordinary depth gauge, the plane of the backing plate, and the upper surface of the platen, and the contact area is limited And the processing error of the backing plate plane in the measurement area, the value measured by this method cannot completely and accurately reflect the actual situation of the relative height difference between the 1:40 slope and the upper surface of the platen
