Description

Technical Field

[0001] The utility model relates to the technical field of rail connection, in particular to a reinforced rail connection plate. Background Art

[0002] Rails are the main components of railway tracks. Their function is to guide the wheels of locomotives and vehicles forward, withstand the huge pressure of the wheels, and transmit it to the sleepers. The connection between two adjacent rails requires the use of connecting plates, which have the advantages of simple operation, stable structure and good connection effect.

[0003] The prior art discloses a railway rail joint reinforcement device with announcement number: CN220746453U, which includes rail one, a connecting groove, rail two, a connecting block, a connecting plate, a limiting block, a limiting nail, a limiting sleeve, a limiting groove, a clamping block and a clamping slot. When in use, by inserting the connecting block on rail two into the connecting groove on rail one, and then inserting the limiting block on the connecting plate into the connecting block, the connection between rail one and rail two can be made more stable. Then, the connecting plate is fixed to rail one and rail two by the limiting nail, and then the limiting sleeve is slid into the connecting plate, so that the limiting sleeve slides on the limiting nail, so that the limiting nail slides into the limiting groove on the limiting sleeve, and the clamping block on the limiting sleeve is clamped into the clamping slot on the connecting plate, so that the limiting sleeve can permanently limit the limiting nail.

[0004] In the above-mentioned utility model, the threaded holes connecting the limit pins and the rails 1 and 2 are exposed to the air, and external impurities can easily enter the interior of the threaded holes. Since the internal space of the threaded holes is small, it is difficult to clean the impurities inside, which brings inconvenience to the connection of the utility model. Secondly, since the connecting plates have a certain weight, the operator will accelerate the consumption of physical strength by manually transferring multiple connecting plates, which reduces the practicality of the use of this utility model.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides a reinforced rail connecting plate with the following advantages:

[0018] (1) The present invention adopts a cavity plate. When the reinforced rail connecting plate is actually used, the operator manually pulls out two sets of rubber covers, and then clamps the output end of the external air pump with a set of connecting pipes.

[0019] (2) The present invention adopts ball bearings. Before the installation work, the connecting plate needs to be moved. The operator puts the connecting plate on the surface of the first rail or the second rail by hand. The multiple sets of ball bearings will contact the surface of the first rail or the second rail. At this time, the connecting plate is moved horizontally. The multiple sets of ball bearings are subjected to friction and roll inside the multiple sets of second ball sockets respectively. Since the surfaces of the multiple sets of ball bearings are smooth, the connecting plate can be easily moved and used. When it is necessary to apply lubricating oil to the surfaces of the multiple sets of ball bearings, the control valve is opened and closed, and then the lubricating oil is poured into the interior of the inner cavity through the liquid guide tube. The lubricating oil inside the inner cavity can enter the interior of the multiple sets of second ball sockets through the multiple sets of connecting holes. This part of the lubricating oil can contact the multiple sets of ball bearings. The set ball bearings can save effort in transferring the connecting structure, thereby improving the practicality of the reinforced rail connecting plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Working principle:

[0038] When the reinforced rail connecting plate is actually used, the operator manually pulls out the two sets of rubber covers 19, and then connects the output end of the external air pump to a set of connecting pipes 18. When the external air pump is working, air can enter the interior of a group of cavity plates 10 on the same side through a set of connecting pipes 18, and the air inside the group of cavity plates 10 on the same side can be ejected through the filter screen 20 on the same side. The ejected air can be blown out of the interior of a group of threaded through holes 12 on the same side, and the cleaning of the other group of threaded through holes 12 can be achieved by the same operation. When cleaning is completed, move the connecting plate 7. When the connecting block 8 is inserted into the limiting groove 5, the docking groove 6 and the through groove 28, the two sets of connecting bolts 14 are inserted clockwise into the two sets of threaded blind holes 9 and the two sets of threaded through holes 12. Then, the two sets of sealing covers 15 are respectively inserted into the interiors of the two sets of mounting blind holes 11, and then multiple sets of rubber balls 16 are inserted into the interiors of multiple sets of first ball sockets 13. Through the provided cavity plate 10, the rail surface can be conveniently cleaned. The interior of the threaded hole is provided to facilitate the connection of the reinforced rail connecting plate.

At this time, the connecting plate 7 is moved horizontally, and the multiple sets of balls 23 are subjected to friction and roll inside the multiple sets of second ball sockets 22 respectively. Since the surfaces of the multiple sets of balls 23 are smooth, the connecting plate 7 can be easily moved and used. When it is necessary to apply lubricating oil to the surfaces of the multiple sets of balls 23, the control valve 27 is opened and closed, and then the lubricating oil is poured into the interior of the inner cavity 21 through the liquid guide tube 26. The lubricating oil inside the inner cavity 21 can enter the interior of the multiple sets of second ball sockets 22 through the multiple sets of connecting holes 24, and this part of the lubricating oil can contact the multiple sets of balls 23. Through the provision of the balls 23, the connection structure can be transferred with little effort, thereby improving the practicality of the reinforced rail connecting plate.
