Abstract

The utility model relates to a shockproof oblique end face steel rail. A perpendicular end face steel rail is slantwise cut into an oblique end face steel rail which is inclined to the side face of the steel rail and is perpendicular to the treading face of the steel rail. Two oblique end face steel rails are connected by a clamping plate to form an oblique rail gap. Contact lines formed after the abrasion of wheels of a locomotive and a vehicle and the steel rails are crossed with the oblique rail gap, namely, when the wheels of a locomotive and a vehicle pass through the oblique rail gap, the wheels simultaneously contact the two oblique end face steel rails. As a result, the utility model effectively prevent the strong impact, the vibration and the noise generated in the way that when the wheels of a locomotive and a vehicle pass through a vertical rail gap, the wheels suddenly separate from one steel rail, and then suddenly contact the other steel rail.

Description

Vibrationproof formula angled end-face rail

The utility model belongs to the rail track technical field, and what relate to is a kind of vibrationproof formula angled end-face rail.

Rail track is connected into by thousands of one steel rails, because the influence of temperature and the restriction of prior art condition, rail must leave certain clearance between the end face when connecting, this gap is rail gap, rail gap brings many serious harm to railway operation, locomotive, the wheel of vehicle produces strong impact through rail gap the time, vibration and noise, seriously influencing locomotive, the quality of vehicle and circuit and application life, limited the speed of service of train, comfort level when influencing the passenger and riding, people are in order to solve because of the caused a series of disastrous effects of rail gap, adopted multiple complicated technology method to reduce rail gap, for example: weld long guiding principle rail, because welded long rail technical sophistication, costly, system-wide has been promoted the use of certain difficulty, therefore the existence of rail track rail gap is inevitable in the near future, capturing on the difficult problem of rail gap, people only pay attention to eliminating rail gap, can change the structural performance of rail gap and ignored change end of rail shape, thereby can prevent to impact, the practicality of vibration and noise.

The end of existing rail exists following scarce limit:

1, the end face of rail is vertical promptly perpendicular to the side and the tread of rail, therefore rail has been formed a vertical rail gap perpendicular to rail side and tread after connecting, the wheel of locomotive, vehicle during through vertical rail gap be suddenly with the end separating of an one steel rail, contact with the end of another one steel rail suddenly again, therefore produce strong impact, vibration and noise, along with the load-carrying of train and the raising of speed, this impact, vibration and noise be aggravation thereupon also.

2, two one steel rails are clamped and connected with bolt, clamping plate, the impact during through vertical rail gap of the wheel of locomotive, vehicle, and vibration has a shearing force to clamping plate, this power concentrates on the rail gap place, influence the application life of clamping plate, and easily cause the pine of nut to move back, jeopardize traffic safety.

3, the formed rail gap of rail that under the low temperature in locality, connects by load be to rail when ground temperature raises be heated expand give and stay distance, this is not apart from dwindling, rail gap is too little, can cause bloated rail accident.Make the circuit torsional deformation, jeopardize traffic safety.Rail gap is too big, can increase impact, vibration.

The purpose of this utility model provides a kind of vibrationproof formula angled end-face rail, the wheel that it can effectively prevent locomotive, vehicle separates with an one steel rail suddenly during through the perpendicular end surface rail, suddenly contact with another one steel rail again and produce strong impact, vibration and noise, and can disperse to reduce shearing force and the corresponding rail gap that dwindles connecting cleat.

Locomotive, the wheel of vehicle is a contact with contacting of rail tread theoretically, this is that given shape by the tread of wheel and rail tread is determined, but in practice, because the plastic strain when wheel contacts with rail, and the wearing and tearing of wheel and rail, the point contact just disappears in the short period of time, and then be formed on the contact wire that transversely has certain width of rail, this contact wire prolongs along with the increase of the wearing and tearing of wheel and rail, and the inclination rail gap that connects in the angled end-face rail intersects, when wheel process inclination rail gap, contact with two angled end-face rail simultaneously, therefore separate with an one steel rail suddenly when effectively having prevented wheel through vertical rail gap, suddenly contact with another one steel rail again and produce impact, vibration and noise, also disperse simultaneously to have reduced shearing force to clamping plate, because the rail gap that the angled end-face rail is formed favours the side of rail, so rail gap is along the vertical distance of the distance of rail on vertically greater than rail gap, therefore compare with vertical rail gap under identical temperature condition, the slit of inclination rail gap can reduce corresponding.

Do detailed explanation below with reference to the accompanying drawings:

Fig. 1 is the three-dimensional assembly diagram of angled end-face rail.

The end face of rail (1) favours rail (5) in Fig. 1, (6) side (3), perpendicular to rail (5), (6) tread (2), with clamping plate (4) with rail (5), (6) formed an inclination rail gap after the connection, because locomotive, the wheel of vehicle and rail tread (2) plastic strain and wearing and tearing and the contact wire and the rail (5) that form when contacting, (6) side (3) is perpendicular, so this contact wire and inclination rail gap intersect, while and rail (5) when wheel process inclination rail gap, (6) tread (2) contacts, effectively prevented locomotive, the wheel of vehicle separates with an one steel rail suddenly during through vertical rail gap, suddenly contact with another one steel rail again and produce strong impact, vibration and noise, also disperse simultaneously, reduced shearing force to clamping plate (4), since between the angled end-face rail both ends of the surface along the distance of rail on vertically greater than the vertical distance between the both ends of the surface, so under identical temperature condition, rail gap can correspondingly reduce.

Claims

1, a kind of vibrationproof formula angled end-face rail, will be in the side (3) that rail (5), (6) vertical end face (7) are cut sth. askew and become to favour rail (5), (6), inclined end face (1) perpendicular to rail (5), (6) tread (2), with clamping plate (4) the inclination rail gap has been formed after connecting in rail (5), (6), it is characterized in that: the end face (1) of rail (5), (6) favours the side (3) of rail (5), (6).
