[0022] Reference Figure 1-3 , further, the position limiting reinforcement mechanism is composed of a slide groove A104, a thread groove 105, a sliding frame 3, a reinforcement block 301 and an adjusting screw 302;

[0023] Slide grooves A104 are embedded on both sides of the upper middle part of the sleeper 1, and a sliding frame 3 is slidably arranged between the inner sides of the slide groove A104. A reinforcement block 301 is fixedly installed below the sliding frame 3. There are several reinforcement blocks 301, which are arranged in parallel in a trapezoidal shape and at equal distances. Adjustment screws 302 are rotatably arranged on both sides of the upper part of the sliding frame 3 through bearings. Thread grooves 105 are embedded on both sides of the upper part of the sleeper 1 near the lower sides of the sliding frame 3, and the adjustment screws 302 are threadedly engaged and rotatably arranged on the inner side of the thread groove 105. The reinforcement block 301 is made of isoprene rubber. When the staff fixes the sleeper 1 and the rail 2, they screw the two sides of the sliding frame 3 to adjust the The screw 302 rotates through the bearing, so that the adjusting screw 302 rotates in engagement with the inner thread of the thread groove 105, pushing the sliding frame 3 to slide downward on the inner side of the slide groove A104, driving a number of trapezoidal reinforcement blocks 301 to slide into a large amount of gravel, which will increase the contact area between the gravel and the gravel, so that when the train runs on the surface of the rail 2 and passes the sleeper 1, the sleeper 1 will not move easily. At the same time, when the outer surface of the reinforcement block 301 made of isoprene rubber with good elasticity, wear resistance and aging resistance comes into contact with a large amount of gravel, the friction between the gravel and the reinforcement block 301 will be increased, so that when the gravel and the reinforcement block 301 have a large friction, it will not easily cause wear.

[0024] Embodiment 2

[0025] like Figure 1-3 As shown, in addition to the embodiment in which the reinforcing block 301 is made of isoprene rubber, the utility model also has another embodiment in which the reinforcing block 301 is made of natural rubber. Since natural rubber has the characteristics of high mechanical strength, wear resistance, high elasticity and pressure resistance, the reinforcing block 301 can slide into a large amount of gravel, so that when extrusion occurs between the reinforcing block 301 and the large amount of gravel, the surface of the reinforcing block 301 will not be easily subjected to a large extrusion force and cracked and damaged.

[0026] Working principle: First, when the staff needs to lay the rails 2, they carry several sleepers 1 and rails 2 to the work site, and place several sleepers on the gravel road surface used for laying the rails in turn, then place two rails 2 between the two sides above the several sleepers 1, and take two pairs of limit frames 4, and push the sliding plates 402 to slide on the inside of the slide groove B401 respectively, drive the damping telescopic rod 403 and the outer spring to expand, and then slide the two pairs of limit frames 4 into the limit grooves A101 close to the two sides of the rails 2 respectively, and drive the limit rod 405 to slide into the inside of the limit grooves B201 on both sides of the rails 2, and then the rubber block B406 under the limit rod 405 slides into the groove B103, squeezing the "U" shaped rubber block B406 to deform, and making the rubber block B406 deform. After the arc surfaces on both sides slide to the arc surfaces on both sides of the inner wall of the slot B103, the rubber block B406 rebounds, so that the arc surfaces on both sides of the rubber block B406 fit with the arc surfaces on both sides of the inner wall of the slot B103, and while completing the clamping, the staff pushes the sliding plate 402 in the opposite direction to slide inside the slide slot B401, driving the opened damping telescopic rod 403 and the outer spring to retract, and then the rubber block A404 slides into the inside of the slot A102, squeezing the "U"-shaped rubber block A404 to deform, and after the arc surfaces on both sides of the rubber block A404 slide to the arc surfaces on both sides of the inner wall of the slot A102, the rubber block A404 rebounds, so that the arc surfaces on both sides of the rubber block A404 fit with the arc surfaces on both sides of the inner wall of the slot A102, and the limited fixation of one of the sleepers 1 is completed. After that, the staff limit and fix other sleepers 1 in the same way, and make the sleepers 1 be used for a long time. When the staff needs to disassemble and replace one of the sleepers 1, they push the sliding plate 402 to slide on the inside of the slide groove B401, drive the rubber block A404 to slide out of the groove A102, and drive the damping telescopic rod 403 and the outer spring to expand, and then pull the limit frame 4 and the limit rod 405 to slide out from the inside of the limit groove A101 and the limit groove B201, drive the rubber block B406 to slide out from the inside of the groove B103. After completing the disassembly of the limit frame 4, the staff pushes the sleeper 1 to slide out from under the rail 2, and slides the new sleeper 1 between the rails 2 and buries the sleeper 1 with a large amount of gravel again. The sleeper 1 and the rail 2 are limited and fixed in the same way. Finally, the staff twists the adjusting screws 302 on both sides of the sliding frame 3 to rotate through the bearings, so that the adjusting screws 302 are engaged and rotated in the inner thread groove 105, and the sliding frame 3 is pushed to slide downward on the inner side of the slide groove A104, driving a number of trapezoidal reinforcement blocks 301 to slide into a large amount of gravel, which will increase the contact area with the gravel, so that when the train travels on the surface of the rail 2 and passes the sleeper 1, the sleeper 1 will not easily move. At the same time, when the outer surface of the isoprene rubber reinforcement block 301 with good elasticity, wear resistance and aging resistance comes into contact with a large amount of gravel, the friction between the gravel and the reinforcement block 301 will be increased, so that when the gravel and the reinforcement block 301 have a large friction, it will not easily cause wear.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
