Description

Technical Field

[0001] The utility model relates to the technical field of track fasteners, in particular to a railway track fastener. Background Art

[0002] The railway track is abbreviated as rail, railway rail, track, etc. The railway track usually consists of two parallel steel rails. The steel rails are fixed on the sleepers, and the roadbed is under the sleepers. The railway track made of steel can bear greater weight than other materials, enabling the train to run without turning.

[0003] When laying the railway track, fasteners are mostly installed on the sleepers, then a certain number of sleepers are laid on the roadbed, and then two parallel steel rails are laid on the sleepers and fixed in position by the fasteners. The existing fasteners mostly fix the screw on the sleeper, then sleeve the pressure plate on the surface of the screw and squeeze the pressure plate by rotating the nut, so that the pressure plate presses down to squeeze and position the steel rail. However, since the screw is directly exposed, it may cause the screw to be frequently eroded by external rainwater and climate during long-term use, resulting in rust on the surface of the screw, which hinders the normal rotation of the nut and affects the later maintenance by personnel.

[0006] The effects achieved by the above components are as follows: First, fix the base to the sleeper, then lay the track on the sleeper so that the track is close to the base. At this time, sleeve the pressure plate on the surface of the screw and rotate the nut with a tool, so that the nut moves up and down along the surface of the screw, and the nut moves along the surface of the screw to squeeze the surface of the pressure plate, so that the pressure plate squeezes one side of the track to complete the extrusion and positioning of the track.

At this time, the winding bolt is rotated by a tool, so that the winding bolt rotates along the inside of the threaded cylinder, and the winding bolt winds and tightens the rope during rotation, causing the rope to pull the second threaded hole tube, thereby completing the auxiliary reinforcement of the pressing plate and reducing the looseness or shaking of the pressing plate during use, and further improving the extrusion and positioning effect of the pressing plate on the track.

[0019] Preferably, a tightening member for fixing the rope end is provided on the side of the pressing plate.

By setting the protection device 5, first manually move the cylinder 51, so that the cylinder 51 drives the round hole block 53 and the rubber pad 52 to move. When the cylinder 51 moves to the position where it completely sleeves on the surfaces of the screw rod 2 and the nut 3, the inner wall of the round hole block 53 coincides with the inner wall of the first screw hole tube 511. At this time, rotate the fastening bolt 54 with a tool, so that the fastening bolt 54 turns into the inside of the round hole block 53 and the first screw hole tube 511 to fix the cylinder 51 and extrude the cylinder 51, so that the cylinder 51 extrudes the rubber pad 52, so that the rubber pad 52 closely fits the surface of the pressing plate 4 under the extrusion of the cylinder 51, so that the cylinder 51 completely wraps the screw rod 2 and intercepts external rainwater.

A rope 63 is fixedly connected to the surface of the winding bolt 62. A second threaded hole tube 64 is fixedly connected to one side of the pressing plate 4. The other end of the rope 63 is sleeved on the surface of the second threaded hole tube 64. By setting the auxiliary device 6, when the pressing plate 4 completes the extrusion positioning of the track, the rope 63 is sleeved on the second threaded hole tube 64. At this time, the winding bolt 62 is rotated by a tool, so that the winding bolt 62 rotates along the inside of the threaded cylinder 61, and the winding bolt 62 winds and tightens the rope 63 during rotation, so that the rope 63 pulls the second threaded hole tube 64, thereby completing the auxiliary reinforcement of the pressing plate 4, reducing the looseness or shaking of the pressing plate 4 during use, and further improving the extrusion positioning effect of the pressing plate 4 on the track.

[0034] Working principle: First, fix the base 1 to the sleeper. At this time, lay the track on the sleeper so that the track is close to the base 1. Then, sleeve the pressing plate 4 on the surface of the screw 2 and rotate the nut 3 with a tool, so that the nut 3 moves up and down along the surface of the screw 2, and the nut 3 moves along the surface of the screw 2 to squeeze the surface of the pressing plate 4, so that the pressing plate 4 squeezes one side of the track to complete the extrusion positioning of the track. At this time, manually move the cylinder 51, so that the cylinder 51 drives the round hole block 53 and the rubber pad 52 to move. When the cylinder 51 moves to the position where it completely sleeves the screw 2 and the nut 3, the inner wall of the round hole block 53 coincides with the inner wall of the first threaded hole tube 511. At this time, rotate the fastening bolt 54 with a tool, so that the fastening bolt 54 turns into the inside of the round hole block 53 and the first threaded hole tube 511 to fix the cylinder 51 and squeeze the cylinder 51, so that the cylinder 51 squeezes the rubber pad 52, and the rubber pad 52 closely fits the surface of the pressing plate 4 under the extrusion of the cylinder 51, so that the cylinder 51 completely wraps the screw 2 and intercepts external rainwater. At the same time, the rubber pad 52 seals the gap between the cylinder 51 and the pressing plate 4, thereby completing the protection of the screw 2 and the nut 3.

[0035] First, the operator can pour lubricating oil into the interior of the storage cylinder 56. The lubricating oil is stored in the storage cylinder 56 under the interception of the film 57. When the operator needs to maintain the screw 2 and the nut 3 after a certain period of time, the ejector pin 58 is manually pressed, so that the ejector pin 58 moves along the interior of the storage cylinder 56 towards the film 57. When the ejector pin 58 moves to the position where it penetrates the film 57, the film 57 is damaged and the interception of the lubricating oil is released, causing the lubricating oil to scatter onto the screw 2 and the nut 3, thus completing the rapid oil filling of the screw 2 and the nut 3.

[0036] When the pressing plate 4 completes the extrusion positioning of the track, the rope 63 is sleeved on the second screw hole tube 64. At this time, the winding bolt 62 is rotated by a tool, so that the winding bolt 62 rotates along the interior of the threaded cylinder 61. During the rotation of the winding bolt 62, the rope 63 is wound and tightened, causing the rope 63 to pull on the second screw hole tube 64, thereby completing the auxiliary reinforcement of the pressing plate 4.
