[0026] The embodiment of the utility model provides a reciprocating rail sliding structure.

[0027] See also Figure 1 , including a horizontal fixing plate 1, the outer surface of which is equipped with a power supply, which can supply power to the electrical equipment in this application.

[0028] See also Figure 1 、 Figure 2 and Figure 3 A rail pulling mechanism 2 is provided below the horizontal fixed plate 1. The rail pulling mechanism 2 includes two active worm gears 201. The two ends of the active worm gears 201 are rotatably connected to the horizontal fixed plate 1. A driving motor is installed inside the horizontal fixed plate 1. The output end of the motor is fixedly connected to the active worm gear 201, so that when the motor is turned on, the two active worm gears 201 can effectively rotate in the same direction or rotate relative to each other at the same time.

[0029] The drive motor is a common electrical device in the prior art. This application will not elaborate on its model or internal structure. It can also be replaced by other power sources.

When the two active worm gears 201 are driven to rotate in the same direction at the same time, the driven worm gear 202 can be driven to move horizontally. When the two active worm gears 201 are driven to rotate relative to each other at the same time, the driven worm gear 202 can be driven to rotate.

[0031] The bottom surface of the driven worm gear 202 is fixedly connected to the gear 1 203 through a connecting rod. The outer surface of the gear 1 203 is meshedly connected to two tooth plates 1 204. The outer surface of the tooth plate 1 204 is slidably connected to a sliding frame 205. The top surface of the sliding frame 205 is slidably connected to the horizontal fixed plate 1. Through the setting of the sliding frame 205, the tooth plate 1 204 is effectively supported and limited. The bottom surface of the sliding frame 205 is fixedly installed with a sliding bar, which slides into the inner wall of the horizontal fixed plate 1, so that the sliding frame 205 is more stable when moving.

[0032] The bottom surface of the gear 1 203 is fixedly connected to a telescopic rod 1 206, and the telescopic end of the telescopic rod 1 206 is fixedly connected to a screw 1 207. The outer surface of the screw 1 207 is threadedly connected to the sliding frame 205. Through the rotation of the telescopic rod 1 206, the screw 1 207 can be driven to rotate at the same time and move up and down on the inner wall of the sliding frame 205.

[0033] One end of each tooth plate 204 is fixedly connected to a connecting plate 1 208, and the top surface of the connecting plate 1 208 is slidably connected to the horizontal fixed plate 1.

The outer surface of the clamping plate 210 is slidably connected to the sliding frame 205. The outer surfaces of the clamping plate 1 209 and the clamping plate 210 are fixedly installed with anti-slip pads. The provision of the anti-slip pads provides more sufficient friction when clamping the new rails.

[0034] See also Figure 1 and Figure 4 A fixing mechanism 3 is provided below the horizontal fixed plate 1. The fixing mechanism 3 includes a driving rod 301. The outer surface of the driving rod 301 is rotatably connected to the horizontal fixed plate 1. A rotating handle is fixedly installed at one end of the driving rod 301. Through the setting of the handle, the driving rod 301 can be driven to rotate more conveniently.

[0035] One end of the driving rod 301 is fixedly connected to the gear 2 302, the outer surface of the gear 2 302 is meshedly connected to two tooth plates 2 303, one end of the two tooth plates 2 303 is fixedly connected to the connecting plate 2 304, the top surface of the connecting plate 2 304 is slidably connected to the horizontal fixed plate 1, and through the setting of the horizontal fixed plate 1, the connecting plate 2 304 is effectively supported and limited, making the two connecting plates 2 304 more stable when moving.

[0036] The outer surface of the tooth plate 303 is slidably connected to the fixing frame 305, the top surface of the fixing frame 305 is fixedly connected to the horizontal fixing plate 1, and a sliding hole is provided on the bottom surface of the fixing frame 305. A sliding rod is fixedly installed on the top surface of the fixing plate 309, and the sliding rod slides in the sliding hole, which effectively limits the fixing plate 309, so that the rotation of the screw rod 307 can only drive the fixing plate 309 to move up and down, and thus cannot rotate.

[0037] The bottom surface of gear 2 302 is fixedly connected to telescopic rod 2 306, the telescopic end of telescopic rod 2 306 is fixedly connected to screw 2 307, the outer surface of screw 2 307 is threadedly connected to the fixing frame 305, and by driving telescopic rod 2 306 to rotate, screw 2 307 can be driven to rotate at the same time.

[0038] One end of the connecting plate 2 304 away from the tooth plate 2 303 is fixedly connected to the fixing plate 1 308, and one end of the screw 2 307 away from the telescopic rod 2 306 is rotatably connected to the fixing plate 2 309. The outer surface of the fixing plate 2 309 is slidably connected to the fixing frame 305, and the inner wall of the connecting plate 2 304 is slidably connected to the ground spike 310. By deeply inserting the ground spike 310 into the roadbed, effective supporting force is provided when pulling the rail, avoiding the situation that the new rail cannot be aligned with the original rail when pulling the rail.

[0039] Working principle: First, rotate the driving rod 301 to drive gear 2 302 to rotate. The rotation of gear 2 302 drives the connecting plate 2 304 at one end of the two tooth plates 2 303 to move closer to each other, and at the same time, the driving screw 2 307 rotates to drive the fixed plate 2 309 to move downward. The movement of the connecting plate 2 304 drives the fixed plate 1 308 to move closer to each other, and cooperates with the downward movement of the fixed plate 2 309 to effectively fix the device on the original rail surface. At this time, the ground spike 310 is again deeply inserted into the roadbed, so that the device effectively provides the supporting force when pulling the rail. Secondly, drive the two active worm gears 201 to rotate relative to each other at the same time, thereby driving the driven worm gear 202 to rotate. The rotation of the driven worm gear 202 drives the connecting plate 1 208 at one end of the two tooth plates 1 204 on the surface of gear 1 203 to move closer to each other. Connecting plate 1 The movement of 208 drives the two clamping plates 209 to approach each other and tightly adhere to the surface of the new rail. At the same time, the rotation of gear 1 203 will drive the rotation of screw 1 207. The rotation of screw 1 207 drives the clamping plate 2 210 to move down and tightly adhere to the top surface of the new rail. At this time, the two active worm gears 201 are driven again to rotate in the same direction at the same time, thereby effectively driving the driven worm gear 202 to move horizontally in the inner wall of the horizontal fixed plate 1 through the meshing force. The movement of the driven worm gear 202 drives the sliding frame 205 and the connecting plate 1 208 to clamp the new rail and move toward the original rail, effectively achieving the ability to clamp the new rail on multiple sides and then slide and pull the rail, avoiding the situation where the device slides when pulling the rail due to insufficient friction on the clamping surface of the new rail, and further making the device more stable.
