Description

Technical Field

[0001] The invention relates to a component on a maintenance device, and more particularly to a clamp of a switch base plate replacement device. Background Art

[0002] Since 2003, China's railways have developed rapidly. As of 2020, the high-speed railway mileage has reached 39,000 kilometers, and the conventional railway mileage has exceeded 100,000 kilometers. China's railways are far ahead in the world in terms of quantity. In order to ensure that they are also second to none in quality, higher and more comprehensive requirements are also put forward for the work of the engineering department. As one of the three key parts of railway line diseases, turnouts occupy an important position in engineering maintenance. They not only directly affect indicators such as line smoothness, but also have a significant impact on line control and other factors that affect the safe operation of the line.

[0003] The inspection and fine-tuning of turnout sections on ballastless high-speed railway lines is an important part of the work of engineering departments. Currently, there is a lack of dedicated equipment at home and abroad, and construction is still at the level of barely using traditional tools. The quality of the work depends on the operator's sense of responsibility and technical level, and the operating efficiency cannot be guaranteed. Some traditional tools (such as rack jacks) not only have poor operating effects, but also pose safety hazards.

[0004] Currently, various hydraulically powered tools have good performance, stable quality and guaranteed safety, but they generally have problems such as high starting height, small lift range and small lifting force, and cannot adapt to existing line conditions.

[0005] There is an even greater lack of supporting tools for the overall lifting of the turnout core. Although various departments have produced a small number of special clamps based on the characteristics of the lines under their jurisdiction, they generally have the disadvantages of poor versatility, bulkiness, low efficiency and poor operating results.

[0006] Especially in the fixation of the turnout rail head, and the relative position during the lifting and lowering process cannot be accurately located, which brings great inconvenience to the actual operation. Summary of the invention
