The rack rail is a rail traffic system suitable for short-distance, medium and small passenger traffic transportation in mountain areas. At present, the standard vehicle is mainly used for coal mine transportation in China, and is mainly used for mountain tourism railways in foreign countries. Although its climbing ability is somewhat weaker than that of a cable plant, it is suitable for longer and more complex routes. In order to realize the climbing effect of the toothed rail, the sleeper of the railway is required to be reliably connected with the toothed rail. At present, no actual operation line of the toothed rail is available in China, and the technology related to the standard rail transit is still in a research and reserve stage, so that the method for connecting the toothed rail and the sleeper is one of the problems to be solved urgently by those skilled in the engineering field. In view of this, it is necessary to design a spring strip type connecting fastener for a rack and a sleeper, to achieve reliable connection of the sleeper and the rack, so as to ensure the safety of running of the rack vehicle.
The situation that the toothed rail and the toothed rail seat cannot be installed in the installation and construction process of the toothed rail is likely to occur due to manufacturing errors or installation errors, particularly in the application of the toothed rail railway, due to the longer line length, after the installation and construction of the multi-section toothed rail, the manufacturing errors or installation errors of the fine toothed rail are likely to be amplified to a certain extent, so that the dislocation phenomenon, namely the problem that the toothed rail and the toothed rail seat cannot be installed or are not installed well, is caused;
