The invention belongs to the technical field of mining machinery, and particularly relates to an overspeed brake vehicle for a toothed rail clamping vehicle. The overspeed brake vehicle comprises a bottom frame, and bearing wheel sets and driving assemblies are arranged at the two ends of the bottom frame; A bearing wheel set is arranged on a clamping rail; A driving assembly is matched with a toothed rail; A top frame is arranged above the bottom frame, the two ends of the top frame are each provided with a brake assembly, and the brake assemblies are located on the outer sides of the clamping rails and suitable for pressing the clamping rails when the top frame moves downwards; An elastic assembly is arranged between the bottom frame and the top frame; An overspeed protector comprises aspeed limiting assembly and an execution part; One end of an execution part is connected with the top frame, and the other end thereof is connected with a bottom frame; A speed limiting assembly is arranged on the bottom frame, connected with the executing component and suitable for driving the executing component when the bottom frame is overspeed. The braking structure of the structure is compact, and the gravity center of the whole overspeed brake vehicle is low. Therefore, the rollover phenomenon caused by the fact that the brake vehicle is heavy in head and light in foot when heavy objects are conveyed is avoided, and then the toothed rail clamping vehicle can stably run.
本发明属于矿山机械技术领域,具体涉及一种用于齿轨卡轨车的超速制动车。包括:底架,底架的两端均设有承载轮组和驱动组件;承载轮组置于卡轨上;驱动组件与齿轨适配;顶架,顶架设于底架的上方,且两端均设有制动组件,制动组件位于卡轨的外侧,适于在顶架下移时压紧卡轨;弹性组件,设于底架和顶架之间;超速保护器,包括限速组件和执行部件;执行部件的一端与顶架连接,另一端与底架连接,适于驱动所述顶架上下移动;限速组件设于底架上,并与执行部件连接,适于在底架超速时驱动执行部件。上述结构的制动结构紧凑,整个超速制动车的重心较低,从而避免了制动车因输送重物时头重脚轻而导致的侧翻现象,继而使齿轨卡轨车行驶稳固。
