Description
Technical field
The utility model belongs to a kind of rail joint.
Background technology
Existing rail is when laying a railway track because rail is in its length direction phenomenon of can expanding with heat and contract with cold, therefore rail with leave the shrinkage joint between rail is connected; Use rail joint clamping plate and bolt to dock, this joint design is simple, and is easy to loading and unloading; But owing to leave the butt joint rail gap, the train wheel that is in operation is increased the impact force of rail gap, thereby the running resistance of train is increased; And generation vibrations; Application life of rail reduces, and maintenance cost increases, and can slide down when serious, security incident such as overturning.And dislocation or " low joint " phenomenon up and down about be prone to taking place.
In order to overcome the operation problem, on March 26th, 2003, Chinese utility model notice of authorization CN2541507Y disclosed a kind of railway track joint, and it mainly comprises two rail, clamping plate and a junction plate; On the rail head face of two rail adjacent end portions, be processed with the groove that adapts with junction plate, junction plate is fixed in the groove through sunk screw, leaves uniform dilatation joint between junction plate sidewall and the recess sidewall, and the junction plate surface is equal with the rail head of rail.But this railway track joint, its junction plate are on the work plane of rail head, and junction plate is connected sunk screw with rail head be again the weakest part of mechanical strength, least withstand shock power.And rail head is directly to contact the parts that train wheel rolls, nature, and the sunk screw silking of this joint design damages many, and application life is not long, and the sunk screw silking damages the maintain and replace trouble.
The utility model content
The utility model technical problem to be solved is: a kind of rail joint is provided; Existing railway interface is improved; Dislocation or " low joint " phenomenon up and down about avoiding the two rails junction to take place, the wheel that reduces operation produces bump and noise in the two rails junction.
The utility model solution is: a kind of rail joint, and it mainly comprises two rail and a pair of yin, yang clamping plate, the yin, yang clamping plate is contained in the junction of two end of rail through bolt clip; It is characterized in that: the web of the rail middle part at two rail adjacent end portions is processed with locating slot respectively one; When two end of rail being drawn close relatively install, the locating slot on two rail forms microscler splicing hole relatively; Above-mentioned positive clamping plate is the positive middle part of a side wherein, has one to connect and perpendicular to the microscler pilot pin of plate face; The generous size of microscler pilot pin is equivalent to two rail when putting together fully, and the formed microscler splicing hole size of growing tall can the holding elongate pilot pin; The positive middle part of above-mentioned cloudy clamping plate also has the through hole that equates with the generous size of microscler pilot pin of positive clamping plate; The length of described microscler pilot pin is greater than a cloudy clamping plate thickness and a rail web of the rail thickness sum, make microscler pilot pin on the positive clamping plate pass the through hole of the microscler splicing hole on the rail, cloudy clamping plate successively after, also leave one section extension.
For the more connection of firm end of rail of a step, avoid dislocation about the generation of two rails junction, the utility model also at two locating holes of extension design of said microscler pilot pin, is inserted with " T " font alignment pin on the locating hole.
Make " T " font alignment pin out of stock for fear of the rail operational shock, the utility model is also established lock pin in the end of said " T " font alignment pin.
Adopt this rail joint of the utility model; Through the microscler pilot pin strictness on the positive clamping plate controlled two sections rail junctions about dislocation and " low joint " phenomenon up and down; Thereby impact that the wheel that has reduced to go produces herein and noise; Prolong the application life of wheel and axletree, bearing and track, improved its operational safety performance.The utility model can carry out online transformation to existing railway and cost is low, saving of work and time.

The specific embodiment
Below in conjunction with the specific embodiment and accompanying drawing, to the further detailed explanation of structure of the utility model.
With reference to accompanying drawing 1 and accompanying drawing 2, a kind of rail joint, it mainly comprises two rail 1 and a pair of yin, yang clamping plate, the yin, yang clamping plate is installed in the junction of two rail 1 ends through bolt 4.
Accompanying drawing 3 expressions; The length of described microscler pilot pin 6 is greater than cloudy clamping plate 2 thickness and a rail web of the rail thickness sum; After making microscler pilot pin 6 on the positive clamping plate 3 pass the through hole 7 of microscler splicing hole on the rail 1, cloudy clamping plate 2 successively, also leave one section extension.Two locating holes 8 of extension design of said microscler pilot pin 6 are inserted with " T " font alignment pin 9 on the locating hole 8; Lock pin 10 is established in the end of said " T " font alignment pin 9.
Accompanying drawing 4 and accompanying drawing 5 expressions, the web of the rail middle part at two rail adjacent end portions is processed with locating slot 5 respectively one; When two end of rail being drawn close relatively install, the locating slot 5 on two rail forms microscler splicing holes relatively.
