Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The device for replacing the grinding stone of the steel rail grinding wagon shown in fig. 1 to 5 comprises a base 1, a lifting platform 3, a rotating platform 4 arranged on the top surface of the lifting platform 3 and a lifting mechanism 2, wherein the lifting platform 3 is connected with the base 1 through the lifting mechanism 2, and the plane where the lifting platform 3 is located is always parallel to the plane where the base 1 is located.
A rail grinding wagon is mainly used for grinding railway rails to eliminate defects such as corrugation, flash, fine cracks on the surface, decarburized layers and the like, and can also be used for repairing the profile of the rails. The grinding stone is a tool used by the rail grinding wagon for grinding the rail, belongs to a consumable product and is similar to a grinding wheel of a grinding machine. The utility model discloses when in-service use, only need set up the grindstone on rotary platform 4 at first, drive 3 parallel lifting of lift platform and realize the accurate location of grindstone afterwards, rotate rotary platform 4 at last and let the grindstone on rotary platform 4 follow the installation that rotates and realize the grindstone. The general grindstone is provided with threads for rotary installation, so that convenient and efficient installation is realized. Because the rotary platform can rotate 360 degrees, the labor intensity of the installation of the grinding stone is greatly reduced.
In order to realize the simplification of the structure on the premise of ensuring the corresponding functions, the following scheme can be selected: the lifting platform 3 is provided with a platform rotating shaft 43, and a bearing 42 is arranged between the rotating platform 4 and the platform rotating shaft 43. As shown in fig. 4, the rotating platform 4 has a bearing 42, so that convenient rotation can be realized, and the installation of the grinding stone is convenient. In general, deep groove ball bearings are preferred for the bearings 42.
In order to realize more accurate positioning of the grinding stone and prevent the grinding stone from sliding off the platform, the following scheme can be selected: a positioning boss 41 is arranged at the geometric center of the rotating platform 4. As shown in fig. 1, 2 and 4, a cavity is provided at the center of the general grinding stone to be matched with the positioning boss 41, and the cavity at the center of the grinding stone can also be provided with a mounting thread, so that the assembly of the boundary during rotation is realized. For the purpose of optimizing the structural arrangement, it is preferable that the bearing 42 is disposed below the positioning boss 41, thereby making the structure more compact.
