Abstract
The utility model provides a safety connecting device for a fork-heel switch rail, which at least comprises a safety connecting plate, wherein the whole safety connecting plate is in an inverted T shape and is arranged between two adjacent spacing irons; threaded holes are formed in horizontal supporting legs on two sides of the safety connecting plate and are fixed on the spacer iron through bolt pairs, and a gap of 1-2mm is reserved between a boss of the safety connecting plate and one side, facing the wing rail, of the fork-heel switch rail. The utility model is applied between the fork-heel switch rail and the wing rail, and the welding spacer iron of the fork-heel switch rail is connected into a whole through the bolt pair, thereby increasing the overall firmness of the fork-heel switch rail; meanwhile, the lug boss of the safety connecting plate plays a role in limiting transverse displacement of the fork and the switch rail, and potential safety hazards caused by the fact that wheels impact the broken surfaces when the fork and the switch rail are broken are prevented.
Description
Technical Field
The utility model belongs to the technical field of fork and point rail technique and specifically relates to a safe connecting device for fork and point rail.
Background
In the prior art, the fork-heel switch rail and the wing rail are fixedly connected through the spacing iron and the high-strength bolt, but gaps exist among the spacing iron, and the collision of wheels can cause the breakage of the fork-heel switch rail at the gaps, so that potential safety hazards are caused.
SUMMERY OF THE UTILITY MODEL
In view of the above, the present invention provides a secure connection for a fork and heel switch rail.
A safety connecting device for a fork-heel switch rail at least comprises a safety connecting plate, wherein the whole safety connecting plate is in an inverted T shape and is arranged between two adjacent spacing irons; threaded holes are formed in horizontal supporting legs on two sides of the safety connecting plate and are fixed on the spacer iron through bolt pairs, and a gap of 1-2mm is reserved between a boss of the safety connecting plate and one side, facing the wing rail, of the fork-heel switch rail.
Furthermore, an adjusting sheet used for adjusting the distance between the lug boss of the safety connecting plate and one side of the fork-heel switch rail facing the wing rail is arranged between the safety connecting plate and the spacing iron.
Further, the adjusting sheet is L-shaped, so that the bottom of the adjusting sheet is conveniently inserted between the safety connecting plate and the spacing iron; the adjusting sheet is internally provided with a notch from the insertion side, and the notch extends inwards to the middle rear part.
The utility model is applied between the fork-heel switch rail and the wing rail, and the welding spacer iron of the fork-heel switch rail is connected into a whole through the bolt pair, thereby increasing the overall firmness of the fork-heel switch rail; meanwhile, the lug boss of the safety connecting plate plays a role in limiting transverse displacement of the fork and the switch rail, and potential safety hazards caused by the fact that wheels impact the broken surfaces when the fork and the switch rail are broken are prevented.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
Example 1
A safety connection device for a fork-heel switch rail is used for connecting and fixing a fork-heel switch rail 1 and a wing rail 2, as shown in figure 1, a first spacer iron 3, a second spacer iron 4 and a third spacer iron 5 are arranged between the fork-heel switch rail 1 and the wing rail 2 at intervals, a first safety connection plate 6 is arranged between the first spacer iron 3 and the second spacer iron 4, and a second safety connection plate 7 is arranged between the second spacer iron 4 and the third spacer iron 5.
The safety connecting plate is integrally in an inverted T shape, threaded holes are formed in the horizontal supporting legs on the two sides of the safety connecting plate, and the safety connecting plate is fixed on the spacing iron through bolt pairs 8, as shown in figure 2.
Because the fork and the switch rail can have longitudinal relative displacement when the turnout is moved, the safety connecting plate can not be tightly attached to the fork and the switch rail. A gap of 1-2mm is reserved between the lug boss of the safety connecting plate and one side of the fork and heel switch rail facing the wing rail. This gap is adjusted by providing a tab 9 between the safety tie plate and the spacer iron.
Specifically, in this embodiment, the adjustment sheet is L-shaped, so that the bottom of the adjustment sheet is inserted between the safety connection plate and the spacer iron; the tab 9 is provided with a notch 10 inwardly from the insertion side, said notch extending inwardly to the middle rear portion. The adjustment of the gap between the lug boss of the safety connecting plate and one side of the fork and the switch rail facing the wing rail is realized through adjusting sheets with different thicknesses.
Finally, it should also be noted that the above list is only one specific embodiment of the present invention. Obviously, the present invention is not limited to the above embodiments, and many modifications are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
