Embodiment Construction

[0027] The design and working principle of the present invention is: the outer wedge-shaped adjustment of the new type of shrapnel type fastener is to buckle the front end of the shrapnel on the bottom of the basic rail, the rear end is raised with a wedge-shaped positioning block, and the supporting boss in the inner cavity of the table plate presses down the shrapnel, that is In the working state, the two ends of the shrapnel are upturned, and the middle is concave. The supporting boss in the middle and the positioning wedge at the rear end make the front end of the shrapnel generate a buckle force of 12KN.

[0028] From the perspective of the overall structure, the new type of shrapnel-type fastener for external wedge adjustment includes base plate 1, shrapnel 2, platen 5, and wedge-shaped positioning block 3. The card slot is fixed between the basic rail and the wedge-shaped positioning block 3; the inclined plane guide iron 7 is fixed on the bottom plate 1 close to the bas...

Abstract

The adjustable outer wedged spring leaf type fastener a one rail track accessory includes one base board, a spring leaf, a wedged locating block, and a platen to fix the spring leaf between the stock rail and the locating block. The wedged locating block is located on the base board and has its tail contacting the vertical wall. The base board has one beveled guide block fixed to its stock rail side and one baffle fixed to its platen side. The adjustable outer wedged spring leaf type fastener has the advantages of simple installation, high safety and reliability, excellent disassembling performance and easy in-situ maintenance.

Description

technical field [0001] The invention belongs to the technical field of construction of roads, railways or bridges, in particular to an improvement of a railway turnout in a railway track accessory. Background technique [0002] After the speed of the railway was increased, domestic sliding bed boards began to use shrapnel and pins to elastically buckle the inner side of the basic rail (Figure 11). According to the comprehensive test results of the Qinshen turnout, the maximum lateral displacement of the basic rail of the switch when the train passed was 1.07 mm, can fully meet the use requirements of passenger-only turnouts, but due to the limitation of the height difference between the basic rail and the AT rail, the strength of the shrapnel and pins is insufficient, and some shrapnel and pins are found to be damaged on site. With the continuous improvement of railway speed, it is an urgent problem to ensure that the sliding bed board is safe, reliable and durable elastical...
