Abstract
The utility model relates to an overhead crossing frog, which is composed of a basic rail, a movable wing rail, a movable core rail, a draw rod, etc. The draw rod is connected with the movable wing rail and the movable core rail, and is used to draw the movable wing rail and the movable core rail to unfold and fold at both sides of the basic rail. When folding, the movable wing rail and the movable core rail can be folded at the contact point with the basic rail and can ride on the basic rail. The idle space of the stationary type frog is eliminated safely, and therefore, the line of the straight strand running of the train is the same as the ordinary line, and the running speed of the side strand running is near to the stationary type frog. The workloads of the curing and the maintenance of the switch are reduced, and the running speed of the straight strand is ensured.
Description
The utility model relates to a kind of railway frog of railway switch.
The railway frog of common railway track switch partly exists idle space, particularly drives a vehicle seldom and the busy situation of main track for the side thigh, and the straight strand eccentric wear of railway frog is serious, application life is short, the maintenance difficulty, in order to address this problem, Japan adopts a kind of formula railway frog more of taking advantage of, this railway frog partly connects with lead curve for straight strand, eliminate idle space, on the side thigh wing rail is raised, make wheel summit and stock rail contour, so take advantage of from the stock rail end face and to cross, finish path and intersect.So straight burst of condition improves, but vehicle all will produce one-shot at every turn by the side thigh, has limited road speed to a great extent, can only be used for small size code channel trouble.
The purpose of this utility model provides a kind of straight strand can eliminate idle space, and side thigh wheel rolls across continuously, operates steadily the railway frog that speed is higher.
The purpose of this utility model is achieved in that
The utility model is made of stock rail, movable wing rail, movable point frogs and pull bar, movable point frogs and movable wing rail are positioned at the stock rail both sides, pull bar links to each other with movable wing rail with movable point frogs, and affect them to move away from the stock rail both sides or close up, a side that contacts with stock rail at movable point frogs and movable wing rail, the flange of rail bottom surface height of movable point frogs and movable wing rail is identical with stock rail rail head apical side height, and its flange of rail bottom shape and stock rail rail head shape are complementary.
The utlity model has following advantage:
1, eliminated idle space just as common line for straight strand, thereby reduced power additional force between wheel track, train operation is steady, and permanent way maintenance is convenient.
2, side thigh train by the time also eliminate idle space, wheel rolls across continuously, the speed of service can be approaching with stiff frog, the permanent way maintenance workload is little, the time and labour saving.
Fig. 1 is the utility model vertical view on the line
A-A sectional drawing when Fig. 2 opens for the side thigh
A-A sectional drawing when Fig. 3 opens for straight thigh
Further narrate the utility model below in conjunction with accompanying drawing:
Referring to accompanying drawing, when train passes through the side thigh, movable wing rail 1 and movable point frogs 2 are by pull bar 3 tractions, close up in contact position and ride on the stock rail 4 with stock rail 4, the supporting rail level is raised, and train is gone over from stock rail 4 crossing-aboves, and the horizontal applied force of wheel is born by the abrasionproof load guard rail 6 that is positioned at side thigh lateral stock rail 5 inboards, abrasionproof load guard rail 6 has reduced the friction of vehicle to movable wing rail 1, and assurance movable wing rail 1 is not opened by crowded.When train passed through straight burst, pull bar 3 traction movable wing rails 1 and movable point frogs 2 were moved away from beyond the gauge of stock rail 4, and train passes through from stock rail 4.
Claims (1)
1, a kind of three-dimensional great-leap-forward railway frog of railway switch, constitute by stock rail, movable wing rail, movable point frogs and pull bar, pull bar links to each other with movable wing rail and movable point frogs, it is characterized in that: movable wing rail and movable point frogs are positioned at the stock rail both sides, a side that contacts with stock rail at movable wing rail and movable point frogs, the rail head bottom surface height of movable wing rail and movable point frogs is identical with stock rail rail head apical side height, and its rail head bottom shape and stock rail rail head shape are complementary.
