Abstract
The utility model relates to a rail joint clamp plate device for railways, in particular to a rail joint clamp plate device capable of eliminating shear stress which is characterized by comprising a rail I, a rail II, a groove, a clamp plate and holes. The groove is arranged on the clamp plate, and the groove has the length L of 35 mm to 45 mm, the depth H of 1.5 mm to 2.5 mm and the radius R of 102.5 mm. The rail joint clamp plate device in the utility model has the advantages of simple structure, low cost, high safety and reliability and simple process, and is convenient in maintenance, and is beneficial to the popularization and application. by using the rail joint clamp plate device, the shear stress on the fishplate can be eliminated, the potential accident when the train runs with heavy load at a high speed is reduced, and the service life of the clamp plate is enhanced.
Description
Technical field: the utility model relates to the railway track joint clamping plate, is specially a kind of elimination shear stress rail joint fixation device.
Background technology: at present, along with the development of China's economic technology, railway is realized at a high speed, heavily loaded, high density means of transportation.Therefore more and more higher requirement has also been proposed for rail and connector clamping plate (being commonly called as splice bar) thereof, also demanding impact toughness and fatigue performance except requiring high strength.Splice bar is the vitals that connects rail, will bear complicated stress effect such as tension and compression, bending, shearing, fretting wear in the work, and operating environment is very complicated abominable, is one of weak link of railway transportation.Be used for checking, keep in repair, change splice bar every year and will spend great amount of manpower and material resources, even more serious is that the splice bar of every hurt is not if discovery in time all may bred once great driving accident.
Summary of the invention: the purpose of this utility model provides at the bottom of a kind of simple in structure, cost honest and clean, safe and reliable, easy to maintenance, has the elimination shear stress rail joint fixation device of groove.The purpose of this utility model is achieved in that it comprises I rail, II rail, groove, clamping plate, hole.Clamping plate are provided with groove.Groove is provided with groove length L, depth of groove H, groove radius R.Groove length L is that 35mm-45mm, depth of groove H are that 1.5mm-2.5mm, groove radius R are 102.5mm.The utility model has the advantages that: honest and clean, safe and reliable, easy to maintenance at the bottom of simple in structure, the cost, and technology simple, be beneficial to and apply.Eliminate the suffered shearing force of splice bar, reduce train high speed, heavy service possibility of accident occurrence, the application life of having improved clamping plate.
Description of drawings: Fig. 1 is the utility model existing product stress deformation figure; Fig. 2 is the utility model structural principle schematic diagram; Fig. 3 is the utility model I-I position structural principle enlarged drawing schematic diagram; Fig. 4 is the utility model I-I position structural principle cross-sectional schematic; Fig. 5 is the utility model groove centre-line cross-section cross-section structure principle schematic; Fig. 6 is the A-A section groove centre-line cross-section generalized section of the utility model groove centre-line cross-section section.
The specific embodiment: it comprises I rail 1, II rail 2, groove 3, clamping plate 4, hole 5.Clamping plate 4 are provided with groove 3.Groove 3 is provided with groove length L, depth of groove H, groove radius R.Groove length L is that 35mm-45mm, depth of groove H are that 1.5mm-2.5mm, groove radius R are 102.5mm.The utility model operating principle and the course of work: clamping plate are placed the both sides of I rail, II rail joint respectively, and bolt passes the hole and fixes, and it is firm to connect.The center of groove is right against two I rail, II rail connection seam center.Because fluted, the power that I rail 1, II rail 2 joints are produced by vibrations can't be concentrated and act on the clamping plate middle part, but peptizaiton is on clamping plate integral body, thereby has eliminated the suffered shearing force of clamping plate.
