Abstract
Disclosed is a load-bearing joint bar used for railway track, which relates to a railway rail mounting block. The formation includes an inside joint bar and an outside joint bar, the outside joint bar has an upper brim leaning against the lateral side of the rail head, the upper brim has a transition shape with the middle part higher than the two ends, and the top face of the upper brim is an inclined plane matching the inclined plane of the wheel. The utility model has advantages that the bar can bear the pressure from wheels while connecting two rails, and the breakage to the joints of rails by wheels is reduced, which is favorable for decreasing joint diseases.
Description
Technical field
The utility model relates to a kind of railway installing component.
Background technology
Joint bar is the parts that are used for connecting two rails.Existing joint bar constitutes the inside and outside two clamping plates that is clipped in the rail web of the rail by two.Rail joint will bear the impact of wheel, vibration and wearing and tearing, rail in use for some time, the joint often easily forms triangular shaped recess, influences traffic safety, on the other hand, rail rolls down for a long time train wheel, and the height of rail often is lower than standard gauge, when the old rail that replacing is worn away, for solving itself and the discrepancy in elevation problem that new rail transition portion exists, the on-the-spot method that adopts the new rail of polishing usually.The shortcoming of this way is both to have reduced the rail surface strength, has caused waste of material, has also increased the site work amount greatly.And the joint bar that is in the joint only works to connect two rails, function singleness.
The utility model content
The purpose of this utility model is for solving the problems referred to above that the rail joint place exists, a kind of connection that can finish two rails is provided, also can making wheel steadily pass through the bearing-type joint bar at rail joint place.
The formation of this bearing-type joint bar comprises inner contact clamping plate and lateral joint clamping plate, it is characterized in that described lateral joint clamping plate have the last eaves that a side leans against the rail head side, described upward eaves is that two ends are low, middle high transition forms, and the end face of last eaves is an inclined-plane that matches with the wheel inclined-plane.This bearing-type joint bar is installed during use in the usual way, and the last eaves height degree of its lateral joint clamping plate matches with the tread height of rail.Train is through the joint time, the moving line of wheel is transferred to the last eaves of lateral joint clamping plate gradually by rail, and then get back on the rail, the pressure of wheel is also by rail joint bar transition gradually laterally, the surge that former cause rail joint place is born changes by the lateral joint clamping plate carries, thereby avoided because of triangular shaped recess or new, relayable rail height difference causes beats, and has improved the stationarity of train operation.For the connection between new rail, can avoid the formation of triangular shaped recess.
Compare with existing like product, the utility model has the advantages that the pressure that also can carry wheel when two rails connects, alleviated the damage of wheel, help reducing joint disease the rail joint place finishing; Also solved the manpower that on-the-spot rail grinding causes when adopting conventional mounting means, the waste on the material resources has improved efficiency.
Content of the present utility model further illustrates with the following Examples.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is that the A of lateral joint clamping plate is to view
Fig. 3 is the schematic diagram that the lateral joint clamping plate are used for the triangular shaped recess joint
Fig. 4 is that the lateral joint clamping plate are used for newly, the schematic diagram of relayable rail joint
The specific embodiment
Shown in Fig. 1～2, the formation of this bearing-type joint bar comprises inner contact clamping plate 8 and lateral joint clamping plate 2, described lateral joint clamping plate 2 have the last eaves 11 that a side leans against rail head 13 sides, the described eaves 11 of going up is that low, the middle high transition in two ends forms, and the end face 12 of last eaves is an inclined-plane that matches with wheel 7 inclined-planes.Inner contact clamping plate 8 can be continued to use the original structure thickening and constitute, and with bolt 9 and locknut 10 this bearing-type joint bar are installed in the usual way.14 is rail among the figure.
What Fig. 3 provided is the schematic diagram that the lateral joint clamping plate are used for the triangular shaped recess joint.1 is rail among the figure, and 3 is triangular shaped recess.
What Fig. 4 provided is that the lateral joint clamping plate are used for newly, the schematic diagram of relayable rail joint.4 is new rail among the figure, and 5 is relayable rail.6 are lower than the depression of new rail for relayable rail.
Claims (1)
1, railway bearing-type joint bar, comprise inner contact clamping plate and lateral joint clamping plate, it is characterized in that described lateral joint clamping plate have the last eaves that a side leans against the rail head side, the described eaves of going up is that low, the middle high transition in two ends forms, and the end face of last eaves is an inclined-plane that matches with the wheel inclined-plane.
