A kind of adaptive superelevation sleeper, it is characterized in that, upper sleeper, one end of lower sleeper are connected by shaft, upper sleeper, lower sleeper the opposite face of the other end on be respectively equipped with upper idler wheel channel and bottom roller slot, hoisting system is installed between upper idler wheel channel, bottom roller slot, hoisting system is made of bolt, supporting rod, idler wheel, roller shaft, it is connected with bolt in the middle part of two crossed longitudinally supporting rods, the upper and lower end parts of supporting rod are flexibly connected with roller shaft, simultaneously on roller shaft, idler wheel contacts idler wheel with upper idler wheel channel, bottom roller slot；The roller shaft of inner terminal is fixed by upper idler wheel channel, the limit of bottom roller slot inward flange, and the roller shaft of outermost end is connect with the thrustor being located on lower sleeper.The adaptive superelevation sleeper of the present invention, can effectively solve the defect present in existing cant setting method, substantially reduce the maintenance workload of railway, and can improve the abnormal abrasion of rail, ensure circuit smooth-going and improve passenger's comfort and travel safety.
Description
Technical field
The present invention relates to railway traffic equipment, especially a kind of adaptive superelevation sleeper.
Background technology
On curved section when driving, due to inertial centrifugal force effect, the dead weight of rolling stock can focus on outside rolling stock
On stock rail, the pressure of foreign stock rail is increased, leads to phenomena such as passenger generates uncomfortable or displacement of goods occur.Therefore handle is needed
High rail is suitably raised, and so that its own gravity of rolling stock is generated an inside horizontal component, to offset inertial centrifugal
Power, reaching makes inside and outside two strands of forces acted on rail uniformly with vertical abrasion equalization, improve stability and the safety of circuit.
China mainly has outer rail to improve two methods of method and wire center height not political reform when superelevation of outer rail is arranged.Mesh
It is preceding it is widely used be that outer rail improves method, that is, keep internal rail absolute altitude constant and only raise outer rail.When superelevation of outer rail value is arranged, adopt
It is calculated with formula, refers to by the average speed of each secondary train of curve in formula, be sweep, on both wired, average speed
It is to be calculated by the speed and weight of consideration every train of diel；When new line designs, average speed is direct line taking
0.8 times of road highest desin speed, therefore each curved section of actual track can only be arranged according to a determining average speed
Unique corresponding superelevation of outer rail fixed value.But during actually runing, operation that different trains pass through the curved section
Speed is different, thus the centrifugal force that train generates also differs, and when train speed is more than average speed, curve sets super in fact
Height is not enough to the effect of equilibrium centrifugation power, and superelevation is owed to generate；Conversely, being then superelevation.In this periodical train load
Under effect, the bad phenomenons such as damaged, the abnormal abrasion of rail of sleeper crush-cutting, concrete crosstie shoulder block easily occur for 3 in Curve Segment, accelerate
The deterioration of line status increases 3 in Curve Segment track maintenance and repair workload, and even traffic safety is threatened when serious.
Invention content
It is an object of the invention to provide one kind can automatic adjusument superelevation of outer rail, reduce maintenance workload, protect
It demonstrate,proves circuit smooth-going and improves the adaptive superelevation sleeper of passenger's comfort and traffic safety.
The adaptive superelevation sleeper of the present invention, including sleeper, which is characterized in that sleeper is divided into sleeper, lower sleeper, upper rail
Pillow, one end of lower sleeper are connected by shaft, and shaft is located in lower sleeper, immovable to rotate, and upper sleeper can be around the shaft
Rotation；Upper sleeper, lower sleeper the opposite face of the other end on be respectively equipped with upper idler wheel channel and bottom roller slot, upper idler wheel channel, lower rolling
Hoisting system is installed, hoisting system is made of bolt, supporting rod, idler wheel, roller shaft, crossed longitudinally two supports between race
It is connected with bolt in the middle part of bar, the upper and lower end parts of supporting rod are flexibly connected with roller shaft, and idler wheel on roller shaft, rolls simultaneously
Together by multiple rows of crossed longitudinally supporting rod parallel series, idler wheel contacts wheel shaft with upper idler wheel channel, bottom roller slot；Inner terminal
Roller shaft is fixed by upper idler wheel channel, the limit of bottom roller slot inward flange, and the roller shaft of outermost end and the pushing tow being located on lower sleeper fill
Connection is set, the oil cylinder pushing hoisting system of thrustor makes sleeper rotate around the axis, to be lifted upper sleeper.
The adaptive superelevation sleeper of the present invention is the principle that can be rotated upwardly and downwardly under hoisting system effect using upper sleeper,
According to the different actually required superelevation values of running speed automatic adjusument train, operation principle is,
Pushing tow by thrustor and outer drawing, make hoisting system be moved back and forth in slot, and supporting rod angle of inclination increases therewith
Or reduce so that upper sleeper is rotated upwardly and downwardly around the shaft positioned at lower sleeper, to reach increase and reduce foreign stock rail absolute altitude
Purpose the actual motion speed of train is transmitted to by speed measuring device when train also has certain distance apart from point of tangent to spiral
Central processing unit is computed rear thrustor real-time pushing tow respective horizontal distance and then adjusting superelevation of outer rail again, reaches row
Superelevation value needed for vehicle completes the automatic adjustment of the adaptive superelevation of outer rail.
The adaptive superelevation sleeper of the present invention, can effectively solve the defect present in existing cant setting method, significantly
The maintenance workload of railway is reduced, and the abnormal abrasion of rail can be improved, ensure circuit smooth-going and improves passenger's comfort
With travel safety.
