[0021] See attached Figure 1 and 2The utility model is a point rail straightener structure, the main structure includes a frame 1, the bottom of the frame 1 is supported by a plurality of legs, the frame 1 is provided with a plurality of conveyor rollers 2, the conveyor rollers 2 are driven to rotate by a motor, the point rail is hoisted onto the conveyor rollers 2 during the straightening operation, and the movement of the point rail is achieved by the rotation of the conveyor rollers 2, the frame 1 is symmetrically connected to the sliding connection with a moving frame 3 on both sides, the frame 1 is provided with a telescopic rod 4 for driving the moving frame 3 to slide, the specific telescopic rod 4 adopts an oil cylinder structure, which has more sufficient power and can realize efficient and accurate hydraulic straightening operation, the telescopic rod 4 is used to drive the moving frame 3 to move toward the point rail, one of which Support blocks 5 are symmetrically welded or bolted on the moving frame 3, and a straightening block 6 is welded or bolted on the other moving frame 3. Such a structure uses the conveying roller 2 to convey the portion of the point rail that needs to be straightened to the moving frame 3, and one of the moving frames 3 moves toward the point rail so that the support block 5 on it contacts one side of the point rail, and then the moving frame 3 on the other side also moves toward the point rail so that the straightening block 6 contacts the other side of the point rail, and after contact, the straightening block 6 is continuously driven to move to achieve mechanical pressure on the point rail by the straightening block 6, thereby achieving mechanical straightening of the bent portion of the point rail. After the bent portion is straightened, the conveying roller 2 is used to drive the point rail to continue to move, so that the point rail Another part that needs to be straightened is transported to the mobile frame 3, so that continuous straightening operations at multiple positions on the entire pointed rail can be achieved, which greatly improves the efficiency of straightening the pointed rail; the straightening block 6 is located in the area between the two supporting blocks 5. Such a structure enables both sides of the curved part of the pointed rail to be effectively supported when the straightening block 6 applies force, thereby avoiding excessive bending during the straightening process of the pointed rail and ensuring the accuracy of straightening. A replacement groove 7 is provided on the straightening block 6, and the replacement groove 7 runs through the side of the straightening block 6 facing the pointed rail. A top block 8 is movably connected in the replacement groove 7. Such a structure enables the straightening block 6 to indirectly contact the side of the pointed rail through the top block 8, and the top block 8 and the pointed rail are in direct contact. The degree of inclination of the side surface that contacts the rail varies according to the model of different point rails. Therefore, when straightening point rails of different shapes, it is only necessary to replace the matching top block 8 to achieve uniformity of the force applied by the straightening block 6 to the point rail, making the straightening of the point rail more efficient and accurate. A positioning column 9 is connected to the replacement groove 7 along a transverse sliding path. The positioning column 9 is movably connected to one side of the top block 8. When the top block 8 is disassembled and assembled, it is only necessary to slide horizontally to release the connection between the positioning column 9 and the top block 8, making the replacement step of the top block 8 simpler, and the structure of the replaced top block 8 more solid, ensuring the accuracy and adaptability of the straightening of different types of point rails.

[0022] Preferably, see Attachment Figure 3The top block 8 is slidably connected to the replacement groove 7 along the vertical direction, and one side of the top block 8 is inclined. The inclined structure can better fit the side of the point rail. Such a structure makes it possible for the top block 8 to be positioned only vertically before and after replacement, and the plug-in cooperation of the laterally sliding positioning column 9 and the top block 8 is used to realize the accurate limitation of the vertical position of the top block 8, thereby making the vertical position of the top block 8 more secure, avoiding the tilting or shaking of the top block 8 during the straightening process, and further ensuring the accuracy of the straightening operation.

The positioning column 9 is slidably connected in the slide groove 10, and a compression spring 11 is provided between the positioning column 9 and the end of the slide groove 10. Such a structure can slide the positioning column 9 toward the inside of the slide groove 10 to compress the compression spring 11 before the top block 8 is replaced, leaving space for the replacement of the top block 8. After the replacement is completed, the positioning column 9 is released, and under the action of the compression spring 11, the positioning column 9 automatically slides and plugs into the side of the top block 8, and maintains the plug-in state with the top block 8 under the action of the elastic force, thereby making the limiting operation of the top block 8 simpler and the limiting effect more solid.

[0024] Preferably, a shift block 12 is provided on the positioning column 9, and the positioning column 9 can be slid by moving the shift block 12, thereby avoiding the situation where the depth of the replacement groove 7 is too large to facilitate the sliding operation of the positioning column 9, and further improving the efficiency of replacing the top block 8.

[0025] Preferably, see Attachment Figure 4 , the limit blocks 13 are symmetrically welded or bolted on both sides of the top block 8. The setting of the limit blocks 13 can prevent the reverse bending and deformation of the two sides of the point rail during the process of the straightening block 6 applying force to the point rail, thereby avoiding the reverse bending of the point rail caused by excessive straightening, thereby ensuring the accuracy of the point rail straightening. The limit blocks 13 are provided with a pressure sensor 14. The setting of the pressure sensor 14 can monitor the bending degree on both sides during the straightening process of the point rail, and realize real-time control of the force applied to the point rail, so as to accurately adjust the degree of force when the force is insufficient, and further ensure the strength and accuracy of the point rail straightening.

[0026] Preferably, a top plate 15 is provided on the top of the support block 5. The setting of the top plate 15 allows the support block 5 to contact the side of the point rail while the top plate 15 limits the top position of the point rail, preventing the point rail from slipping vertically when the inclined side is compressed, thereby ensuring the stability of the point rail position during the straightening process.
