Description

Wedge type steel tie

Technical field

The utility model belongs to Machine Design manufacturing field, and in particular to a kind of wedge type steel tie.

Background technique

Common sleeper has wooden sleeper, reinforced concrete sleeper, three kinds of pressure ring steel tie on mine rail route.Wooden rail Pillow mainly carries out Ka Dao by railway spike, general only to exist since wooden sleeper is apt to rot, service life is short, timber cost is again high It is laid with and uses on the longer panel track circuit of the length of service.Reinforced concrete sleeper and pressure ring steel tie are by sleeper Pressure ring rail is fixed, pressure ring when reinforced concrete sleeper and pressure ring steel tie are recycled in underground, on sleeper It can not be just multiplexed again by external force destruction.Either belong to can not for wooden sleeper or reinforced concrete sleeper and steel tie The material being used in turn is repeated in underground.In addition during being laid with and removing rail, the iron hammer swung is easy to that railway spike will be helped Personnel hurt, and are also easy to stick up sky when raising track using crowbar, personnel are operationally very dangerous, also inconvenient.

It can not be reused to solve regular sleeper, reducing sleeper overlapping investment and underground, frequently to transport bring various Cost.We determine to design it is a kind of it is more scientific, be suitable for the Novel sleeper that underground is frequently used in turn feature.It is this Novel sleeper should guarantee that the track gauge after being laid with controls between 898mm ~ 905mm, and allow for bearing underground most The current needs of large-tonnage mine car.We seek technical breakthrough from the principle of regular sleeper Ka Dao first.Pass through early period Demonstration repeatedly determine the original pressure ring Ka Dao of steel tie being designed to drift card road mode, sleeper can be efficiently solved in this way The problem of pressure ring can not reuse after being destroyed by external force.Wedge type I-steel sleeper is designed from the preceding phase and is processed, to scene batch Amount examination installation demonstration is modified repeatedly, total time-consuming eight wheat harvesting periods in front and back.Technology is mature at present, and adopts in Fenghuangshan Mine underground Popularize in an all-round way on pick crossheading track circuit and use.

Utility model content

In order to solve above-mentioned the shortcomings of the prior art, the utility model provides one kind, and to can adapt to underground frequently all Turn the wedge type steel tie used, structure is simple, ingenious in design, easy to use.

To achieve the above object, the wedge type steel tie of the utility model design, including pillow, setting are on the pillow Interior fixture block and outer fixture block, the interior fixture block bottom end is provided with and matched first groove of rail foot surface, the outer fixture block bottom end It is provided with the second groove, first groove and second groove are relatively set into the card slot that can place rail foot surface, institute It states and is provided with drift Ka Dao in the second groove, the drift card is provided with dismountable drift in road.

Preferably, the drift and rail contact position are arranged to inclined-plane.When use between card slot and rail Gap fits like a glove, and to avoid drift not be the not tight rail of card, is exactly drift card problem not in place.

Preferably, the spacing between the interior fixture block and the outer fixture block is 80 ~ 90mm.

Preferably, the interior fixture block and outer fixture block are fixed by welding on the pillow.

Preferably, the drift length is 190 ~ 210mm, with a thickness of 20mm, drift inclined-plane segment length is 160 ~ 180mm。

Preferably, one end of the drift is provided with limit hole, is provided with pin shaft in the limit hole.

The utility model has the beneficial effects that:

First, the wedge type steel tie of the utility model is convenient for disassembly and assembly, can repeat to be used in turn in underground, both solve general Logical sleeper is apt to rot, can not repeat the problem of being used in turn, and reduces the overlapping investment of material and underground transportation cost；

Second, the sweep of the utility model card slot must fit like a glove with the sweep of rail foot surface, outer fixture block The drift Ka Dao of drift must be reserved in design, drift inclined design must fit like a glove with card slot reserved space, keep away The not tight rail of drift card or drift card problem not in place are exempted from, very strict to whole welding process requirement, effect is aobvious It writes；

Third, clamping structure is stablized when steel rail laying, is laid with and removes the mode of rail than original railway spike and pressure ring card Road mode is operationally more convenient, can repeat to be used in turn in underground.

In figure: fixture block, 3- outer fixture block, the first groove of 4-, the second groove of 5-, 6- drift Ka Dao, 7- wedge in 1- pillow, 2- Iron, 8- limit hole, 9- pin shaft, 10- rail.

Specific embodiment

The utility model is described in further detail in the following with reference to the drawings and specific embodiments.

As shown in Figure 1, the wedge type steel tie of the utility model, including pillow 1, the interior card being arranged on the pillow 1 Block 2 and outer fixture block 3, interior 2 bottom end of fixture block are provided with and matched first groove 4 in 10 bottom surface of rail, outer 3 bottom end of fixture block It is provided with the second groove 5, first groove 4 is relatively set into the card that can place 10 bottom surface of rail with second groove 5 Slot is provided with drift card road 6 in second groove 5, dismountable drift 7 is provided in drift card road 6.

Specifically, as shown in Fig. 2 ~ 4, the drift 7 is arranged to inclined-plane with 10 contact position of rail.When use with card slot and steel Gap between rail 10 fits like a glove, and to avoid drift 7 not be the not tight rail 10 of card, is exactly that drift 7 blocks problem not in place.It is described Spacing between interior fixture block 2 and the outer fixture block 3 is 80 ~ 90mm.The interior fixture block 2 and outer fixture block 3 are fixed by welding in institute It states on pillow 1.7 length of drift is 190 ~ 210mm, and with a thickness of 20mm, drift inclined-plane segment length is 160 ~ 180mm.It is described One end of drift 7 is provided with limit hole 8, and pin shaft 9 is arranged in the limit hole 8.

Specific embodiment of the present utility model is as follows: the distance between fixture block 3 is 896mm, interior fixture block outside 1 both ends of pillow The distance between 2 and outer fixture block 3 are 84mm, and the sweep in fixture block size and card slot must comply fully with layout design and want It asks.The sweep of card slot must fit like a glove with the sweep of 10 bottom surface of rail, and outer fixture block 3 must be reserved in design 6 space of drift card road of drift 7.In addition the design length of drift 7 is 200mm, and with a thickness of 20mm, drift inclined-plane segment length is 170mm, drift inclined design must fit like a glove with the card slot reserved space at 1 both ends of pillow.

When steel rail laying 10, rail 10 is put into the card slot at 1 both ends of pillow, the drift 7 of insertion is squeezed into card with iron hammer In slot, it is clamping rail 10 that pin shaft 9 is inserted into when the limit hole 8 on drift 7 gets groove position.When removing rail 10, only It needs to get the drift 7 in 1 both ends card slot of pillow using iron hammer opposite direction.The mode of this dismounting rail 10 is than original Railway spike and pressure ring card road mode it is operationally more easy, while also solve regular sleeper can not underground repeat turnover make The problem of using.

Specific embodiment of the present utility model described above does not constitute the restriction to scope of protection of the utility model. Any other various changes and modifications that any technical concept according to the present utility model is made should be included in practical In novel scope of protection of the claims.
