For example, patent CN201560368U discloses a manual hydraulic gauge adjuster suitable for ordinary bolt fastening sleepers, but it adopts a unilateral gauge adjustment method and requires a ground fulcrum. At present, ballastless integral track beds are generally used in my country's high-speed railways. It is impossible to find the support point, and once the gauge is over-adjusted, it is inconvenient to return to the adjustment
There are also some gauge adjusters that are time-consuming and labor-intensive to carry because of their heavy weight, making it inconvenient to move

Embodiment Construction
[0030] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These descriptions are descriptive and exemplary only.
[0031] see Figure 1~3 , Figure 9 as well as Figure 10 , the hydraulic rail gauge adjuster of the present invention includes a fixed hook part 10 and a moving hook part 20 hooked to two rails 100 and 200 respectively, and a connecting rod part 30 connecting the fixed hook part 10 and the moving hook part 20, A pair of hydraulic cylinders 21, 22 are symmetrically installed on the movable hook portion 20 and can respectively apply thrust to both sides of the rail bottom of the rail 200. When the movable hook portion 20 hooks the rail 200, the pair of hydraulic cylinders 21, 22 22 are respectively positioned at the inside and the outside of hooked steel rail 200 rail bottoms.
[0032] The hydraulic rail gauge adjuster of the present invention also includes a handle 31 to facilitate the di...

The invention relates to a hydraulic rail gauge adjuster. The hydraulic rail gauge adjuster comprises a fixed hook part and a movable hook part which respectively hook the two side surfaces of the rail bottoms of the two rails, as well as a connecting rod part connected with the fixed hook part and the movable hook part, wherein a pair of hydraulic cylinders respectively applying thrust to the two side surfaces of the rail bottoms of the rails are symmetrically mounted on the movable hook part, and when the movable hook part hooks a rail, and the pair of the hydraulic cylinders are respectively positioned on the inner side and the outer side of the rail bottom of the hooked rail. Through the adoption of the hydraulic rail gauge adjuster, the accuracy of the gauge adjustment is ensured, and the work efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of rail gauge adjustment; in particular, the invention relates to a hydraulic rail gauge adjuster. Background technique [0002] When the train runs on the line, a lateral force is generated on the rail, and the deviation of the gauge will cause the train to snake. Track gauge is an important content of track static precision. For ballastless lines, China’s standard inspection requires a gauge deviation of ±1mm and a gauge change rate of 1 / 1500. A higher standard is adopted in some sections of Guangzhou-Shenzhen, Shanghai-Hangzhou, and Beijing-Shanghai: gauge deviation -0.5mm. Fine gauge gauge adjustment has become an important part of ballastless line laying and routine maintenance. The higher and higher requirements for gauge accuracy also require corresponding operating tools and operating methods to match it. [0003] Some railway gauge adjustments in my country adopt the traditional manual crowbar mo...
