Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see the appendix Figure 1 Appendix Figure 4 and attached Figure 5 An embodiment of this utility model provides a rail transport limiting and anti-derailment device, including a base plate 1, a plurality of outer shells 3 fixedly connected to the top of the base plate 1, a motor 4 fixedly connected to the inner wall of the plurality of outer shells 3, an end cap 10 slidably connected to the opposite side of the plurality of outer shells 3, a disc 21 fixedly connected to the output end of the motor 4, a transmission rod 5 fixedly connected to the rear side of the disc 21 near the edge, a plurality of elliptical rings 6 slidably connected to the outer wall of the transmission rod 5, a slider 7 fixedly connected to the outer wall of the plurality of elliptical rings 6, a rotating shaft 8 rotatably connected to the opposite side of the slider 7, a buffer wheel 9 fixedly connected to the outer wall of the rotating shaft 8, and a gripping and fixing mechanism 2 fixedly connected to the top of the plurality of outer shells 3, the gripping and fixing mechanism 2 being used for rail fixed transport;

[0033] Specifically, the base plate 1 provides a stable bearing platform for the equipment, ensuring that it can withstand the weight of the rails and various forces generated by the operation of the equipment itself during transportation, maintaining the stability of the overall structure. The outer shell 3 prevents external dust and debris from entering and resists collisions and squeezing that may be encountered during transportation. The motor 4 converts electrical energy into mechanical energy, laying the foundation for the subsequent transmission process. The slider 7 and the outer shell 3 work together to ensure the accuracy of the slider 7's movement and, through the constraint of the outer shell 3, prevent deviation or shaking during movement, ensuring the stability of the entire transmission system.

[0034] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 6 The gripping and fixing mechanism 2 includes a bracket 201. The bottom of the bracket 201 is fixedly connected to the top of the outer shell 3. A lead screw 202 is rotatably connected to the inner wall of the bracket 201. A crank handle 203 is fixedly connected to the front end of the lead screw 202. A crossbeam 204 is threadedly connected to the outer wall of the lead screw 202. A protective shell 205 is slidably connected to the top of the crossbeam 204. A second motor 206 is fixedly connected to the inner wall of the protective shell 205. A wheel 207 is fixedly connected to the output end of the second motor 206. Multiple sliding grooves 208 are opened on the inner wall of the wheel 207. A column 209 is slidably connected to the inner wall of the multiple sliding grooves 208. A gripper 210 is fixedly connected to the bottom of the column 209.

[0035] Specifically, bracket 201 ensures that the entire mechanism will not deform or be damaged during operation, providing a stable physical environment for fixing the rail. Slide 208 provides precise guidance for the movement of column 209. Grip 210 can fit tightly against the surface of the rail, increasing the contact area and improving the stability and reliability of gripping. It ensures that sufficient friction and gripping force are provided when gripping the rail, preventing the rail from slipping during transportation. Protective shell 205 provides a safe protective environment for motor 206, preventing external dust, moisture and debris from entering the interior, avoiding damage to motor 206 due to external factors, and extending the service life of motor 206.

[0036] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The bottom of the base plate 1 is fixedly connected to multiple support columns 12, the top of the outer shell 3 is fixedly connected to a control box 17, the bottom of the support columns 12 is fixedly connected to a chassis 13, the bottom of the chassis 13 is fixedly connected to an anti-slip pad 14, the top of the base plate 1 is rotatably connected to multiple rotating columns 15, and the outer wall of the multiple rotating columns 15 is fixedly connected to rollers 16.

[0037] Specifically, the support column 12 and the chassis 13 work together to withstand the weight of the equipment itself and various dynamic loads generated during rail transportation, ensuring that the equipment will not tilt or shake when stationary or during transportation. The anti-slip pad 14 can effectively prevent the equipment from sliding, ensuring that the equipment is fixed in position during rail loading and unloading or waiting for transportation. The roller 16 can maintain good rolling performance, ensuring that the rail can smoothly reach the designated position.

[0038] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 A hinge 11 is fixedly connected to the front side of the outer shell 3. Multiple ventilation holes 18 are opened on the outer wall of the outer shell 3. The outer wall of the slider 7 is slidably connected to the inner wall of the outer shell 3. The outer wall of the end cap 10 is fixedly connected to the outer wall of the hinge 11. A nameplate 19 is fixedly connected to the top of the protective shell 205. Rubber pads 20 are fixedly connected to the adjacent sides of the gripper 210.

[0039] Specifically, the end cap 10 is fixedly connected to the hinge 11, ensuring that the end cap 10 and the hinge 11 will not loosen or fall off during use. This also facilitates the maintenance and repair of the equipment, greatly shortens the repair time, and improves work efficiency. The nameplate 19 is printed with important parameters. Operators can understand the performance characteristics and usage requirements of the equipment by checking the information on the nameplate 19, thus avoiding equipment damage or safety accidents caused by misoperation.

[0040] Working principle: When motor 4 is turned on, the rotation of motor 4 drives the rotation of disc 21. The transmission rod 5, which is fixedly connected to the edge of disc 21, makes a circular motion and drives the elliptical wheel 6 to move back and forth, converting the rotational motion of transmission rod 5 into horizontal movement. The slider 7 will gradually extend out of the outer shell 3 to fix the rail and realize the lateral movement of the rail during transportation for precise positioning. After pressing, the buffer wheel 9 will rotate with the movement of the rail, making transportation more stable.

[0041] Crank the crank 203 to rotate the lead screw 202 inside the bracket 201. The rotation of the lead screw 202 will drive the crossbeam 204 to move back and forth to transport the rail. Then turn on the motor 206. The rotation of the motor 206 will drive the wheel 207 to rotate together. The slide groove 208 on the wheel 207 will cooperate with the column 209 to retract the gripper 210, so that the gripper 210 can grab and fix the rail, allowing the rail transportation process to proceed safely and stably.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
