Example Embodiment

[0036] The rail gauge adjuster as shown in Fig. 1 includes a connecting rod 4 with the right end connected to the right holder 2 and the left end connected with the hydraulic cylinder 3, the piston rod connector 15 of the hydraulic cylinder 3 is insulated from the left holder 1, and the piston The rod connector 15 is equipped with a scale 10 that can be elastically stretched between the piston rod connector 15 and the cylinder head of the hydraulic cylinder 3. The hydraulic cylinder 3 is connected to the hydraulic control pump 17 through the oil pipe 16, and the hydraulic control pump 17 is connected to the oil cylinder 14. .
[0037] As shown in Figs. 3, 6, and 7, the inner ends of the left clamp 1 and the right clamp 2 for clamping the rail 25 are correspondingly provided with axial connecting plates 26 with radial concentric holes on the front and rear sides. As shown in Fig. 5, the inner end of the piston rod connector 15 of the hydraulic cylinder 3 is provided with an axial screw hole 21, and the outer end is provided with a radial connection hole 22. As shown in FIG. 4, the connecting rod 4 is provided with a stud section 18 at the left end and a radial connecting hole 27 at the right end. As shown in Figure 1, Figure 2, and Figure 3, the inner end of the piston rod connector 15 of the hydraulic cylinder 3 is screwed to the piston rod 8, and the outer end passes through the insulating sleeve 9 with shoulders at both ends and the pin 7 and the left card seat 1. Connected, the connecting hole 22 at the outer end of the piston rod connector 15 and the insulating sleeve 9 are in interference fit; the cotter pin 13 at the outer end of the pin shaft 7 is fixed by a flat washer 11 and a hexagonal slotted nut 12; the left end of the connecting rod 4 and the bottom of the piston cylinder 3 The screw connection, the right end and the right holder 1 are connected by an insulating sleeve 9 with shoulders at both ends and a pin shaft 7, and the connecting hole 22 at the right end of the connecting rod 4 and the insulating sleeve 9 are in interference fit.
[0038] As shown in Fig. 1 and Fig. 2, the outside of the ruler cavity 19 is buckled and compressed with a pressing plate 5 with an arc-shaped recess on the inside. Both ends of the pressing plate 5 are fixed on the piston rod connector 15 of the hydraulic cylinder 3 by screws 6. As shown in Figures 8 and 9, the scale 10 includes a scale cavity 19 fixedly connected to the piston rod connector 15 of the hydraulic cylinder 3 and a movable scale 20 slidable therein, between the movable scale 20 and the bottom of the scale cavity 19 Connected with a spring 24. The hydraulic control pump 17 is a manual pump with an operating handle 23.
