The wheel assembly 4 is supported in the inner side of the wheel rail by adjusting the adjusting and clamping assembly 5, and the stability of the adjusting and clamping assembly 5 and the wheel assembly 4 during adjustment is ensured by the parallel sliding assembly 2.

[0028] The turnout gauge detection work is a new problem faced by China's railway detection. The gauge detection of railway turnout mainly adopts manual inspection, which is low in efficiency and poor in reliability. The large-scale detection vehicle detection and maintenance cost is high, which makes it lack of effective turnout gauge detection equipment to meet the detection demand in daily maintenance. In order to solve such problems, the adjusting and clamping assembly 5 is proposed.

[0029] Embodiment 2

[0030] On the basis of embodiment 1, embodiment 1 solves the technical problems of high maintenance cost and complex detection process of the existing wheel-rail detection device, but there is still a problem that the adjusting and clamping assembly 5 is not stable enough during the adjusting process. In combination with the problems, the specific implementation process is as follows: Figures 1-6 In order to ensure the stability of the adjusting and clamping assembly 5 and the wheel assembly 4 during the adjusting process, the parallel sliding assembly 2 includes short baffles 25 fixedly connected to both ends of the carrier plate 1, two symmetrical slide rails 23 fixedly connected to the top end of the carrier plate 1, sliding blocks 24 slidingly connected to the slide rails 23, support bases 21 fixedly connected to the top end of the sliding blocks 24, two symmetrical support rods 22 fixedly connected between the two short baffles 25, and the support bases 21 slidingly connected to the outer sides of the support rods 22.
