Detailed Description
The following describes the technical solution of the present invention with reference to the accompanying drawings and specific embodiments.
Example one
Referring to the attached drawings 1-3, the utility model provides a railway line switch rail spare position laser inspection appearance, including left thigh rail and right thigh rail, left thigh rail includes first concatenation rail 11 and second concatenation rail 12, right thigh rail includes third concatenation rail 21 and fourth concatenation rail 22, all fix through sleeper 30 between first concatenation rail 11 and second concatenation rail 12, third concatenation rail 21 and the fourth concatenation rail 22, still include laser instrument 41 installed on left thigh rail, base 42 is installed through dismantling the subassembly in the bottom of laser instrument 41;
the outer wall of the base 42 is symmetrically provided with clamping plates 424, the clamping plates 424 are fixedly provided with positioning blocks 425, wherein the positioning blocks 425 are arranged to prevent the fat edge of the steel rail on one side of the non-acting edge of the steel rail head from influencing the measurement precision during measurement (the fat edge of the steel rail means that the top of the steel rail is pressed by a wheel to extrude a thin sheet);
the disassembling component comprises a fixing hole 423 arranged on the base 42, a fixing groove 421 for fixing the laser instrument 41 is arranged on the side wall of the base 42 far away from the clamping plate 424, a fastening bolt is arranged outside the fixing hole 423, and the fastening bolt penetrates through the fixing hole 423 to be fixedly arranged on the laser instrument 41;
