Embodiment Construction

[0036] The rail gauge adjuster shown in Figure 1 includes a connecting rod 4 whose right end is insulatedly connected to the right deck 2, and the left end is connected to the hydraulic cylinder 3. The piston rod connector 15 of the hydraulic cylinder 3 is insulated and connected to the left deck 1. 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 Fig. 3, Fig. 6 and Fig. 7, the inner ends of the left card holder 1 and the right card holder 2 for clamping the rail 25 are correspondingly provided with axial connecting plates 26 with radial concentric holes. As shown in FIG. 5 , the inner end of the connecting head 15 of the piston rod of the hydraulic cylinder 3 is provided...

Abstract

A gauge adjuster used for railing and railway repair, includes a right end insulated connected to the right lock and a left end connected to the coupling bar of a hydraulic cylinder with the piston head insulated connected to the left lock. A retractable dividing ruler is fixed on the piston head which is extendable between the piston head and the cylinder cover. The cylinder is connected to a control pump via an oil pipe.

Description

technical field [0001] The invention relates to a rail gauge adjusting device. Background technique [0002] The gauge adjustment of the existing lines in our country all adopts the manual crowbar method to adjust the rails based on experience, it is difficult to grasp the accuracy, and the labor intensity of group work is high. The maximum speed of the trains running on the passenger dedicated line is 350km / h, which has high requirements on the parallelism, level difference and gauge error of the rails. The disadvantages of manual crowbar shifting are obvious, and it is not suitable for the laying and maintenance of high-speed passenger dedicated lines. Contents of the invention [0003] The purpose of the present invention is to provide a rail gauge adjuster. [0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: rail gauge adjuster, including the connecting rod whose right end is insulatedly connected wit...
