The specific embodiment
Be described in further detail below in conjunction with the utility model of embodiment, but embodiment of the present utility model is not limited thereto.
Embodiment 1:
For overcoming the defective that adopts fixed forms such as railway spike, pre-embedded bolt, perforated bolt to occur in the existing sleeper technology, the utility model proposes the solid anchoring position of sunken bottom circumference pass sleeper, can not only strengthen the stability of sleeper body 1, can also improve the safety of rail transport, the structure of sleeper body 1 as shown in Figure 1, in actual application, sleeper body 1 is arranged by the track direction, rail 2 is layed in the two ends of sleeper body 1 equally along the track direction, and by pressing guidance tape to fix, as shown in Figure 2.The utility model improves the structure of pressing guidance tape, make press guidance tape in fixing rail 2 inlay card in the top of sleeper body 1, and fix by the bolt assembly of being located on the sleeper body 1, the design of inlay card part, make its structure more stable, effectively prevented from pressing guidance tape with becoming flexible that rail 2 vibrations may occur, it is very reasonable to design, can be applicable to as in the track transmission fields such as colliery transportation applied range.And in the utility model, sleeper body 1 forms for being built by steel concrete, also has advantages such as good stability, long service life, maintenance expense are low.
Fig. 3 as shown in Figure 3, presses the integrative-structure of guidance tape for being welded by pressing plate 7 and projection 8 for pressing the mounting structure schematic diagram of guidance tape, and is fixed in the top of sleeper body 1 by bolt assembly.In the utility model, the structure of this bolt assembly comprises bolt 3 and the nut 4 that is threaded, when reality is used, bolt 3 can adopt T type bolt, fixed by the installing hole of being located on the sleeper body 15, as shown in Figure 3, Figure 4, installing hole 5 is for vertically being arranged in the sleeper body 1 and for the strip channel that bolt T type termination is passed through, being the rectangular channel 6 that is provided with clamping bolt T type termination bottom it.When set bolt 3, the T type termination of bolt 3 is put into along installing hole 5, when rectangular channel 6 positions, rotating bolt 3 can be connected in the T type termination of bolt 3 in the rectangular channel 6, prevents that bolt 3 is suggested outside the installing hole 5.
For better realizing the utility model, also be provided with the groove 9 of inlay card projection 8 at the top of installing hole 5, as shown in Figure 3, pressing plate 7, projection 8 from top to bottom set gradually, projection 8 is connected in the groove 9, and pressing plate 7 is positioned at projection 8 tops and forms the fixedly positioner of rail 2 with sleeper body 1.And by said structure as can be known, pressing guidance tape is the positioner that is set on the bolt 3, therefore, also is provided with the connecting hole 10 for bolt 3 suits on its structure, and this connecting hole 10 is located at respectively on pressing plate 7, the projection 8.When the pressure guidance tape is installed, only need bolt 3 is got final product along connecting hole 10 suits, projection 8 just with the placement of pressing guidance tape with groove 9 phase clampings, 4 tops of being located at pressing plate 7 of nut, and be threaded with bolt 3, maintenance and change also very convenient is installed firmly, only need tighten or unclamp nut 4 can operate, and has many advantages such as save time, laborsaving.
In the actual fabrication process, projection 8 can be designed to square structure, and namely the cross section of projection 8 is square, certainly, is the use of better fit projection 8, and the cross section of groove 9 also should be arranged to square structure, makes projection 8 lucky energy inlay cards in the groove 9 of installing hole 5.When practical application, the practical function of projection 8 then is equivalent to timber wedge (that is: the space of filling implements makes its firm short wooden stake, wood chip etc.) and is filled in the installing hole 5, reduced the space of bolt 3 at installing hole 5, reduce the bolt 3 front, rear, left and right amplitude of rocking in use, improved the security performance of track.When actual fabrication, projection 8 can carry out welding processing on existing pressing plate 7 bases and be made, and simultaneously, digs groove 9 at sleeper body 1, and manufacturing process is very simple, and the more effective cost of manufacture of having saved has market value.
For further strengthening the stability of said structure, improve the safety factor of track, the utility model has also proposed following design: as shown in Figure 5, the screw rod cross section of bolt 3, the cross section of connecting hole 10 structure that all is square, in the time of in screw rod is set in connecting hole 10, be subjected to the restriction of square structure, can prevent that bolt 3 from the screwing and rotate of nut 4, using very convenient.Certainly, the utility model also can adopt the rounded structure of traditional screw rod, and namely as shown in Figure 6, the screw rod cross section of bolt 3, the cross section of connecting hole 10 be rounded structure all.
The utility model is simple in structure, and is reasonable in design, adopts the design of projection 8 and square bolt to strengthen the stability of track greatly, its installation, changes also very conveniently, comprises the steps: that (1) lay sleeper body 1 successively by the diatom direction; (2) T type termination one end with bolt 3 inserts in the installing hole 5, and rotation T type termination makes in its rectangular channel 6 that is connected in installing hole 5 bottoms; (3) press guidance tape at the other end suit of bolt 3, make projection 8 inlay cards of pressing the guidance tape bottom in the groove 9 at installing hole 5 tops, screw nut 4 then and fix.When needs are changed sleeper body 1, unclamp nut 4, take out and press guidance tape, propose can change and keep in repair it behind the bolt 3, simple to operate, quick.
Embodiment 2:
The only difference of present embodiment and embodiment 1 is: adopt the design of cushion block 11 replacement projections 8 as shown in Figure 7.In the present embodiment, press guidance tape mainly to be formed by pressing plate 7 and cushion block 11, shown in Fig. 8 structure, pressing plate 7 and cushion block 11 from top to bottom set gradually, same, be provided with the groove 9 of inlay card cushion block 11 at the top of installing hole 5,7 of pressing plates are to form the fixedly positioner of rail 2 with sleeper body 1, also are provided with the connecting hole 10 for bolt 3 sockets on pressing plate 7 and cushion block 11.In said structure, the effect of cushion block 11 is consistent with projection 8 effects, what can prevent also that bolt 3 from may occur when rail 2 vibrations rocks, certainly, in actual application, because cushion block 11 separates setting with pressing plate 7, during making, only need are processed cushion block 11 separately, are used in combination with pressing plate 7 of the prior art then to get final product; It is also extremely convenient to use, after fixing bolt 3, and socket cushion block 11, pressing plate 7 successively, screwing nut 4 can fix, swift to operate.
In the present embodiment, the connecting hole of being located on the cushion block 11 10 is identical with embodiment 1, its cross section all can adopt square or circular configuration, connecting hole 10 on the pressing plate 7 that is used in combination with it is corresponding with it, also can adopt square or circular configuration, further strengthen the stability of sleeper body 1, improved the security performance of track.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all falls within the protection domain of the present utility model any simple modification, equivalent variations that above embodiment does.
