The application discloses a limiting mechanism for sleigh vehicle braking and a sleigh vehicle, and comprises a braking component, which comprises a main mounting shaft, a fixing buckle fixed on the main mounting shaft and used for fixing the main mounting shaft, and single-side braking structures arranged on the two sides of the main mounting shaft respectively and controlled separately, wherein each single-side braking structure comprises an inner partition plate and an outer partition plate, and the two plates are arranged on the single side of the main mounting shaft in cooperation. Compared with the prior art, the application has the advantages that the left and right single-side braking structures are provided, the driver can control the brake switches on the two sides respectively, the proportional pressing of the single-side braking shaft structure on any side can be realized, when the sleigh vehicle deviates, the sleigh vehicle can be quickly returned to the normal state through the increased braking force on the other side, when the braking shaft structure touches the ground, the rigid impact is converted into elastic buffering through the compression of the buffering spring along the buffering shaft, the instantaneous excessive braking force is avoided to cause the sleigh vehicle to lose control or violently shake, and the compression degree of the buffering spring can be adjusted and set, so that the application is suitable for different terrains and grounds.

The utility model relates to the technical field of single crystal furnace supporting structures, in particular to a single crystal furnace damping supporting structure which comprises a plurality of damping assemblies, each damping assembly comprises a fixing sleeve, a connecting rod, a damping spring, a limiting sleeve and a sealing ring, and the end of the connecting rod penetrates through the fixing sleeve and is in sliding connection with the fixing sleeve; a mounting groove is formed in the top of the connecting rod in the axial direction, and the connecting rod is sleeved with the damping spring. The extension section of the damping spring is matched with the mounting groove to limit offset of the spring and improve stability, the limiting sleeve is in threaded connection with the connecting rod, the compression amount of the spring can be adjusted during mounting, the damping spring is convenient to disassemble and replace during later maintenance, and the defect that a traditional fixedly-mounted spring is difficult to replace is overcome. By means of the design, the stability of the damping spring in the using process is guaranteed, later maintenance is facilitated, and compared with a traditional damping spring installation mode, the practicability and reliability of the single crystal furnace damping supporting structure are improved.
