A stepping self-moving tail train equipped with a drag-reducing moving mechanism

Abstract

The invention belongs to the field of supporting technology and equipment after efficient and rapid tunnelling. In order to reduce running resistance, increase running speed and achieve self-moving of the train by reducing or avoiding manpower, the invention provides a train with a reducing resistance moving mechanism for a stepping self-moving tail. A pair of lifting arms which control the self-moving train to lift up and drop down is arranged between a rigid frame unit of the self-moving train and support sliding rails corresponding to the two sides of the bottom of the self-moving train, the lifting arms are driven by rigid frame lifting oil cylinders, piston rods of the rigid frame lifting oil cylinders are connected with the lifting arms, and cylinder bodies of the rigid frame lifting oil cylinders are connected with a rigid frame unit. According to the train with the reducing resistance moving mechanism for the stepping self-moving tail, by means of lifting and dropping of the lifting arms, the stepping tail train and the supporting rails conduct supporting and running alternatively, the self-moving resistance is reduced, rolling steel wheels of the lifting arms run relative to the supporting rails in a rolling mode, and the frictional resistance in the running process is reduced.

Description

technical field [0001] The invention belongs to the field of high-efficiency and rapid excavation post-excavation supporting technology and equipment, and specifically relates to a rear-use train with a moving mechanism for reducing resistance. Background technique [0002] The tail of the self-moving machine is the key equipment for ensuring transportation after efficient and rapid excavation. Its tail is connected to a self-moving train with a length of about 160 meters. , the overall weight is large and the walking resistance is large. In the past, there are two walking methods: one is to use tires to walk, but this mechanism cannot meet the equipment’s walking under harsh working conditions on the bottom plate; the other is to lay tracks and use roller walking mechanisms. The method has strong adaptability, but the track cannot move by itself, and the laying of the track increases the labor intensity and auxiliary working time of the workers, and the cost is relatively h...
