Technical Field

[0001] The utility model relates to a measuring ruler, in particular to a measuring ruler for measuring the height between a gear box and a sand spreading pipe and a rail surface. Background Art

[0002] The distance between the locomotive gearbox and the track surface needs to meet the design requirements, so it is necessary to measure the distance between the locomotive gearbox and the track surface. The industry currently uses a flat ruler and a steel ruler to measure the distance between the locomotive gearbox and the track surface. The flat ruler is placed on the track surface, and the steel ruler measures the distance from the flat ruler to the bottom of the locomotive gearbox to the flat ruler surface. This measurement method is easy to slide because the flat ruler and the steel ruler are unstable during the measurement process, and the position needs to be adjusted repeatedly, resulting in low measurement efficiency and large measurement errors.

[0003] The sand sprayed from the locomotive sand-spreading pipe can increase the friction of the wheels. The damage and deformation of the sand-spreading pipe will affect the performance of the locomotive and may even cause an accident. Therefore, the distance between the sand-spreading pipe and the track surface must also meet the design requirements, otherwise the sand-spreading pipe needs to be replaced and repaired. The industry currently uses a flat ruler and a steel ruler to measure the distance between the sand-spreading pipe and the track surface. The flat ruler is placed on the track surface, and the steel ruler measures the distance between the bottom of the sand-spreading pipe and the surface of the flat ruler. This measurement method uses a flat ruler and a steel ruler to slide easily, and the positioning of the flat ruler and the steel ruler is unstable during the measurement process.

DETAILED DESCRIPTION

[0022] like Figure 1 , Figure 2 As shown, the utility model gearbox, sand-spreading tube and rail surface height measuring ruler comprises a horizontal ruler body 3, a horizontal ruler sliding ruler frame 4, a rotating seat 6, a vertical ruler body 10, a vertical ruler frame 9, a digital display reading device 7, and a measuring plate 11. The horizontal ruler body 3 extends in the horizontal direction, and the horizontal ruler body 3 can be slidably positioned in the horizontal ruler sliding ruler frame 4. The horizontal ruler sliding ruler frame 4 is a rectangular frame structure that penetrates the horizontal opposite ends. The horizontal ruler body 3 passes through the horizontal ruler sliding ruler frame 4 and the two ends protrude out of the horizontal ruler sliding ruler frame 4 respectively. The horizontal ruler sliding ruler frame 4 can slide left and right relative to the horizontal ruler body 3. The back side wall of the horizontal ruler sliding ruler frame 4 is provided with a threaded hole, and the fixing bolt passes through the threaded hole to locate the relative position of the horizontal ruler sliding ruler frame 4 and the horizontal ruler body 3. The surface of the horizontal ruler body 3 adjacent to the port of the horizontal ruler sliding ruler frame 4 is provided with a scale line and a reading. The bottom surfaces of the two ends of the horizontal ruler body 3 are respectively connected with a positioning base 2 that can be positioned on the rail surface, and the positioning base 2 is connected to the bottom of the two ends of the horizontal ruler body 3 by welding or riveting. The inner bottom end of the positioning base 2 is also connected with a positioning probe 1 that can be mutually clamped and positioned with the side wall of the track 14. When the measuring ruler is positioned on the track surface of the track 14, the bottom surface of the positioning base 2 is attached to the track surface of the track 14, and the positioning probe 1 and the inner side wall of the track 14 are mutually clamped and positioned. The positioning probe 1 can effectively prevent the horizontal ruler body 3 from slipping, ensuring that the horizontal ruler body 3 of the measuring ruler is stably and reliably positioned on the track 14.
