Description

Technical Field

[0002] Rails are the main components of railway tracks. The function of rails is to guide the wheels of locomotives and vehicles forward, bear the huge pressure of the wheels, and transfer it to the sleepers. When installing rails, rail clamps are required to complete the clamping and fixing of the rails. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses a wear-resistant rail presser with publication number: CN213142655U, comprising a sleeper, a guide rail, a rail pressing mechanism, a pressing tongue, a wedge-shaped locking plug, a pressure plate, a base, bolts, protective pads, spring pads, flat washers, pressure blocks and nuts. When in use, the installation hole on the sleeper is used to accurately position the rail presser so that the rail presser is firmly fixed on the sleeper through bolts, and then the protective pad is used to effectively isolate the internal mechanism from the external air to prevent rusting of the device, and the guide rail is pressed by the pressing tongue arranged in the rail pressing mechanism, and then the nut is threadedly connected to the bolt to fix the rail pressing mechanism. At the same time, the arrangement of the spring pad and the flat washer strengthens the bolt fixing and stabilizing effect of the device, and then the anti-wear pad arranged at the connection between the pressing tongue and the guide rail reduces the wear between the components of the device when it is in use, thereby improving the wear resistance of the device and extending the service life. The operation of the device is completed through the above.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a double-body reinforced anti-drop rail clamp, which has the following features:

[0018] Beneficial effects:

The gas can push a group of piston plates on the same side. The group of piston plates on the same side will drive a group of T-shaped cross bars on the same side to move horizontally. In this process, the group of piston plates on the same side and the group of gantry frames on the same side will squeeze the group of Elastic spring, at this time, close the two groups of control valves on the same side. When the internal space of a group of square tubes on the same side is not sealed, the gas inside a group of transparent gas cylinders on the same side will leak.

When one end of the multiple groups of plug columns 19 respectively passes through the multiple groups of plug holes 21, the installation of the multiple groups of T-shaped columns 9 is completed. When the two groups of pressing tongues 7 press down the rails, when the extension shaft 22 rotates, the inclined surfaces of the multiple groups of inclined blocks 25 push the multiple groups of rotating plates 29 respectively, and the multiple groups of rotating plates 29 rotate with the multiple groups of positioning columns 26 as the central axis respectively. The multiple groups of rotating plates 29 push the multiple groups of metal balls 31 respectively, and the multiple groups of metal balls 31 and the multiple groups of mounting plates 28 squeeze the multiple groups of telescopic springs 32.

By setting the mounting box 2, a group of threaded structures can be rotated to achieve the two The adjustable use of the tongue pressing device 7 improves the practicality of the double-body reinforced anti-falling rail pressure device. At the same time, according to the above operation, when the two groups of tongue pressing devices 7 contact the rails, the installation of the rails is completed. At this time, the output end of the external inflation device can be clamped with one end of a group of air inlet pipes 33. When the external inflation device is powered on, the gas can enter the interior of a group of square tubes 12 on the same side through a group of air inlet pipes 33. The gas inside this group of square tubes 12 can enter the interior of a group of transparent air storage cylinders 14 on the same side through a group of air outlet pipes 34 on the same side. The gas can push a group of piston plates 36 on the same side. The group of piston plates 36 on the same side will drive a group of T-shaped cross bars 38 on the same side to move horizontally.
