The invention relates to a novel railway rail splice connecting joint which comprises a steel rail joint and two rail splices. The two rail splices are mounted on the two sides of the steel rail jointthrough bolt fixing. The novel railway rail splice connecting joint further comprises rubber shock pads, and the rubber shock pads are fixed between the steel rail joint and the rail spices. The novel railway rail splice connecting joint further comprises bonding materials. The rubber shock pads are bonded between the steel rail joint and the rail spices through the bonding materials. According to the novel railway rail splice connecting joint, the rubber shock pads are bonded to the outer side of the steel rail joint and the inner sides of the rail splices through the bonding materials, bolts are connected with two steel rails through two lines of bolt holes, a good buffer function is achieved on vibration generated by train running through good shock absorption performance of the rubbershock pads, and a certain function is achieved on safety of train running; and the technical problems that in the existing rail splice connecting technology, it can be guaranteed that the phenomena of loosening and breaking do not happen after long-time connection of the steel rails, and a slowdown function cannot be achieved on vibration noise generated by train running are solved.
Description
technical field [0001] The invention relates to a connection joint of railway rails, in particular to a novel railway rail fishplate connection joint. Background technique [0002] The current rail connection method is the fishplate connection technology, and the fishplate (track joint splint), commonly known as the splint, plays a connecting role at the track joint. The method of using the fishplate technology is to use the fishplate at the broken joint of the two rails, that is, place the two fishplates on both sides of the two rails, and the two rails and the fishplate have bolt holes of the same specification. The two steel rails are fixedly connected by bolts to fix the two fishplates on the two steel rails, and finally the two steel rails become a whole, and the train can run. However, the existing technology of connecting rails with fishplates only connects two rails through fishplates. During the operation of the train, it will produce adverse effects such as vibrat...
