Description

Technical Field

[0001] The utility model relates to a sleeve type open bridge deck fastener, in particular to a sleeve type open bridge deck fastener used in the field of railway track technology. Background Art

[0002] An open bridge deck generally refers to the deck of a railway steel bridge. The load-bearing surface is composed of multiple steel beams. When laying railway tracks on an open bridge deck, ballast is generally not laid. Instead, the sleepers are directly fixed to the steel beams with bolts and other components. The sleepers used in this track structure are generally wooden sleepers or composite (or synthetic) material sleepers. This is to improve the stability of the track structure, reduce the impact of the wheel and rail at the rail joint, and reduce track vibration and noise.

[0003] The specification of Chinese patent CN209353169U discloses a fastener assembly for an open bridge deck track, comprising a sleeper, a buffer pad, an iron pad, a threaded spike, a rail, a gauge block, a T-bolt, a spring bar, a flat washer and a nut. A buffer pad is laid on the sleeper, an iron pad is placed on the buffer pad, the iron pad and the buffer pad are fixed to the sleeper through threaded spikes, a rail is placed in the rail bearing groove of the iron pad, and a gauge block is placed between the rail and the iron pad; the T-bolt is embedded in the plum blossom hole of the iron pad, the U-shaped mouth of the spring bar is clamped on the T-bolt, the spring bar and the flat washer are connected and fixed to the T-bolt through a nut, one end of the spring bar is fixed on the gauge block, and the other end of the spring bar is fixed on the iron pad. Through the above technical scheme, it is convenient to adjust the left and right and high and low positions of the rails, and it is convenient to adjust the longitudinal resistance of the rails to achieve different line resistances.

[0004] The specification of Chinese patent CN203334183U discloses a fastener structure for the open bridge deck track of a steel beam bridge, wherein a shoulder is arranged on the iron pad, a gauge adjustment block is arranged on the inner side of the shoulder, one side of the gauge adjustment block forms a snap fit with the track, and the other side forms a limit fit with the shoulder, and the elastic bar is buckled on the gauge adjustment block. The advantages of this utility model are: simple structure and easy installation; low cost and convenient promotion; the gauge adjustment block can adjust the gauge at will, which can effectively ensure the geometric shape of the track; the pads are classified, and the fastener resistance value can be adjusted in a targeted manner to effectively reduce the interaction between the beam and the rail; the component performance is stable and can be used permanently.

[0005] When adjusting the track gauge and height of the bridge line and replacing the anti-wear pad, it is often done by unscrewing the threaded spikes that fix the iron pad, which causes damage to the regional wood fiber near the spike holes. Repeated unscrewing of the threaded spikes will cause the wooden bridge sleeper to lose its holding force and rainwater will flow into the spike holes, causing the internal corrosion of the bridge sleeper and failure, thus failing to maintain the track gauge well. Utility Model Content

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that the traditional method is to unscrew the threaded spikes that fix the iron pad, which causes damage to the regional wood fiber near the spike holes. Repeated unscrewing of the threaded spikes will cause the wooden bridge sleeper to lose its nail holding force and rainwater will flow into the spike holes, causing the inside of the bridge sleeper to decay and fail, thereby failing to maintain the track gauge well.

[0007] In order to solve the above problems, the utility model provides a sleeve type open bridge deck fastener, including a sleeper, a rail is fixedly connected to the top of the sleeper, two groups of spike holes are symmetrically drilled on the top of the sleeper on both sides of the rail, threaded spikes are detachably connected in the spike holes, a pad is symmetrically and detachably connected above the sleeper, and one end of the two pads close to each other both contacts the rail, screw holes corresponding to the spike holes are drilled on the pad, sleeves extending into the threaded spikes are threadedly connected in the screw holes, a clamping block is fixedly connected to the top of the pad close to the rail, a limit block is sleeved on the clamping block, and the limit block contacts the rail at the bottom close to the rail, and the limit block and the clamping block are fixedly connected to the pad by bolts.

[0008] In the above-mentioned open bridge deck fastener, it is effectively achieved that the wood fibers inside the sleeper will not be damaged when the sleeve is unscrewed multiple times, thereby better maintaining the track gauge and extending the service life of the sleeper.

[0009] As a further improvement of the present application, the threaded spike and the spike hole are fixedly connected by anchoring glue.

[0010] As a further improvement of the present application, a rubber sleeve is sleeved on the threaded spike located above the base plate, and the bottom of the rubber sleeve is in contact with the base plate.

[0011] As a further improvement of the present application, a dust box mechanism is detachably connected to the sleeper, and the dust box mechanism includes a connecting plate that engages with the sleeper.

[0012] As another improvement of the present application, storage boxes are symmetrically fixedly connected to both ends of the connecting plate, and the two storage boxes and the connecting plate form a U shape.

[0013] As another improved supplement of the present application, a clamping sleeve is fixedly connected to one end of the storage box away from the rail, a cylindrical handle is detachably connected inside the clamping sleeve, and a cleaning brush is detachably connected to the bottom end of the cylindrical handle.

[0014] As another improved supplement of the present application, a thread groove is bored at the bottom end of the cylindrical handle, a connecting shaft corresponding to the thread groove is fixedly connected to the top end of the cleaning brush, and the connecting shaft is threadedly connected to the thread groove.

[0015] To sum up, this scheme can be realized. When the track gauge and height of the bridge line are adjusted and the anti-wear pad is replaced, two spike holes can be punched on the sleeper first, and then a high-strength and tough threaded spike is embedded in the spike hole through anchor glue, so that the threaded spike fits tightly with the spike hole, and rainwater will not penetrate into the sleeper through the spike hole. At this time, the pad is placed on the sleeper so that the screw hole and the threaded spike coincide, and then the sleeve is inserted into the threaded connection of the threaded spike, which effectively achieves the goal of not damaging the wood fiber inside the sleeper when the sleeve is unscrewed multiple times, thereby better maintaining the track gauge and extending the service life of the sleeper.

[0025] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0026] The first implementation method:

[0027] Figure 1-4A sleeve-type open bridge deck fastener is shown, comprising a sleeper 1, a rail 2 is fixedly connected to the top of the sleeper 1, two groups of spike holes 7 are symmetrically drilled on the top of the sleeper 1 on both sides of the rail 2, threaded spikes 5 are detachably connected to the spike holes 7, a pad 3 is symmetrically and detachably connected to the top of the sleeper 1, and the two pads 3 are in contact with the rail 2 at one end close to each other, a screw hole 4 corresponding to the spike hole 7 is drilled on the pad 3, a sleeve 6 extending into the threaded spike 5 is threadedly connected in the screw hole 4, a clamping block 15 is fixedly connected to the top of the pad 3 close to the rail 2, a limit block 16 is sleeved on the clamping block 15, and the limit block 16 is in contact with the rail 2 at the bottom close to the rail 2, the limit block 16 and the clamping block 15 are fixedly connected to the pad 3 by bolts, and the threaded spike 5 and the spike hole 7 are fixedly connected by anchor glue.

[0028] This solution can be realized. When the track gauge and height of the bridge line are adjusted and the anti-wear pad 3 is replaced, two spike holes 7 can be first punched on the sleeper 1, and then a high-strength and tough threaded spike 5 is embedded in the spike hole 7 through reinforcing bar glue, so that the threaded spike 5 fits tightly with the spike hole 7, and rainwater will not penetrate into the inside of the bridge sleeper through the spike hole 7. At this time, the pad 3 is placed on the sleeper 1 so that the screw hole 4 and the threaded spike 5 coincide with each other, and then the sleeve 6 is inserted into the threaded connection of the threaded spike 5, which effectively achieves the goal of not damaging the internal wood fiber of the sleeper 1 when the sleeve 6 is unscrewed multiple times, thereby better maintaining the track gauge and extending the service life of the bridge sleeper.

[0029] The second implementation method:

[0030] Figure 5-7 It is shown that a rubber sleeve 10 is sleeved on the threaded spike 5 located above the pad 3, and the bottom of the rubber sleeve 10 is in conflict with the pad 3. A dust box mechanism is detachably connected to the sleeper 1, and the dust box mechanism includes a connecting plate 8 that engages with the sleeper 1. Storage boxes 9 are symmetrically fixedly connected to both ends of the connecting plate 8, and the two storage boxes 9 and the connecting plate 8 form a U shape. A clamping sleeve 11 is fixedly connected to the end of the storage box 9 away from the rail 2, and a cylindrical handle 12 is detachably connected to the clamping sleeve 11, and a cleaning brush 13 is detachably connected to the bottom end of the cylindrical handle 12. A threaded groove is cut at the bottom end of the cylindrical handle 12, and a connecting shaft 14 corresponding to the threaded groove is fixedly connected to the top end of the cleaning brush 13, and the connecting shaft 14 is threadedly connected to the threaded groove.

[0031] The present invention can realize that when the pad 3 is installed, the connecting plate 8 can be clamped on the sleeper 1, so that the storage box 9 is respectively clamped on both sides of the sleeper 1 and fits therewith, and the U-shape formed by the storage box 9 and the connecting plate 8 just leaves an installation position for the pad 3, and then holes are punched through the pile head. The debris generated during the drilling will fall on the surface of the sleeper 1 or fall into the storage box 9. After the holes are punched, the cleaning brush 13 clamped in the clamping sleeve 11 can be taken out to sweep the debris on the surface into the storage box 9 for collection. Then, after the pad 3 is installed in turn, the rubber sleeve 10 is put on the sleeve 6 to prevent rainwater leakage from rusting the threaded spikes 5 and the sleeve 6 and making them difficult to disassemble. The cleaning brush 13 will be damaged after repeated use, and the pad 3 can be taken out of the threaded groove by twisting the connecting shaft 14 for replacement.

[0032] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted by this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
