[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] Example: Figure 1 , 2 As shown in Figure 6, a turnout rail lifting device includes a lifting beam 1 and toothed hook plates 9. Each end of the lifting beam 1 is pin-hinged to one end of two arm plates 5, and the other end of each arm plate 5 is pin-hinged to one end of a chain plate 8. The other end of each chain plate 8 is pin-hinged to the corresponding toothed hook plate 9. The pin-hinging here can be understood as a pin-driven hinge. A chain plate sleeve 2 is fixedly connected between the inner chain plates 8 at both ends of the lifting device. Both ends of the chain plate sleeve 2 are fixedly connected to the middle of the corresponding chain plates 8. A chain plate pin 12 is provided inside the chain plate sleeve 2. The chain plates 8 at both ends of the lifting beam 1 are rotatably connected through the chain plate pin 12. The sleeve 2 prevents displacement of the two opposing chain plates 8 during use, while also improving rigidity and ensuring the stability and reliability of the rail lifting device. To improve the safety of the rail lifting device of this utility model, an anti-detachment mechanism 3 is provided between the chain plate 8 sleeve and the lifting device crossbeam 1. The upper end of the anti-detachment mechanism 3 is connected to the lifting device crossbeam 1, and its lower end is connected to the chain plate sleeve 2. The toothed hook plates 9 at both ends of the lifting device crossbeam 1 are respectively hinged to the side plates 10, and the hook teeth of the toothed hook plates 9 at both ends of the lifting device crossbeam 1 are opposite in direction, thereby ensuring effective and stable clamping of the rail. The two ends of the two side plates 10 are respectively fixedly connected by end plates 11, and the two ends of the side plates 10 are respectively fixedly connected to the corresponding end plates 11 by welding. The hook teeth of each toothed hook plate 9 extend out of the lower end face of the side plate 10 to clamp the rail 13.

[0027] In this embodiment, as Figure 3As shown, the lifting beam structure of this embodiment is as follows: The lifting beam 1 includes a main lifting plate 101, a flat lifting plate 102, large lifting lugs 105, and small lifting lugs 104. It should be noted that the large lifting lugs 105 and small lifting lugs 104 of this utility model are relative; the length and width of the large lifting lugs 105 are both greater than the length and width of the pin lifting lugs 104. The flat lifting plate 102 is arranged horizontally, and its upper surface is fixedly connected to the main lifting plate 101. The main lifting plate 101 and the flat lifting plate 102 are fixed by welding and are arranged perpendicularly. Two small lifting lugs 104 are fixedly welded to the bottom surface of the flat lifting plate 102, which are spaced apart along its length. The two small lifting lugs 104 are symmetrically arranged, with the center of symmetry being the centerline of the length direction of the flat lifting plate 102. Two large lifting lugs 105 are fixed to both ends of the main lifting plate 101 and are fixedly connected to the flat lifting plate 102 by welding.

[0028] Furthermore, each of the two large lifting lugs 105 is provided with a connecting hole 14 adapted to the flat lifting plate 102. The large lifting lug 105 is fitted onto the outside of the flat lifting plate 102 through the connecting hole 14 and is fixedly connected to the flat lifting plate 102 by welding. That is, both ends of the flat lifting plate 102 are inserted into the connecting hole 14 respectively and fixedly connected to the large lifting plate 105 by welding. This connection method not only facilitates the welding of the flat lifting plate 102 and the large lifting plate 105 and makes processing easier, but also improves the rigidity of the lifting beam 1 and reduces the probability of deformation during use.

[0029] The two boom plates 5 at each end of the lifting beam 1 are divided into an inner boom plate 501 and an outer boom plate 502. The inner boom plate 501 and the outer boom plate 502 at each end of the lifting beam 1 are located between the large lifting lug 105 and the small lifting lug 104, respectively. In order to improve the rigidity and stability of the lifting device of this utility model, gaskets 4 are provided on the outside of the beam pin 7 between the inner boom plate 501 and the outer boom plate 502, and between the inner boom plate 501, the outer boom plate 502 and the corresponding large lifting lug 105 and small lifting lug 401. The gaskets 4 and the large lifting lug 105 and small lifting lug 401 limit the axial displacement of the inner boom plate 501 and the outer boom plate 502, preventing them from shifting and shaking during operation, and ensuring the stability and safety of the lifting device of this utility model.

[0030] In this embodiment, see Figure 2 and Figure 3 A crossbeam sleeve 106 is fixedly connected between two small lifting lugs 104. The two ends of the crossbeam sleeve 106 are welded to the corresponding small lifting lugs 104 respectively. A crossbeam pin 7 is installed inside the crossbeam sleeve 106. One end of the crossbeam pin 7 is inserted through the outer side of one of the large lifting lugs 105 and passes through the outer arm plate 502, the inner arm plate 501, one of the small lifting lugs 104, the crossbeam sleeve 106, the other small lifting lug 104, the inner arm plate 501, and the outer arm plate 502 in sequence. It then exits through the other large lifting lug 105 and is locked by a slotted nut 7.

[0031] In an embodiment of this utility model (not shown in the figures), a fixing plate is fixedly connected to the upper middle part of the outer side of the two boom plates 5, which is arranged along the length direction of the crossbeam pin 7. Specifically, the two ends of the fixing plate are fixedly connected to the inner boom plates 501 at both ends of the crossbeam sleeve 106. The fixing plate is located on one side of the crossbeam sleeve and is arranged away from the length direction of the crossbeam sleeve. A fixing plate is also fixedly installed on the upper middle part of the outer side of the two outer boom plates 502 on the other side of the crossbeam sleeve 106. The fixing plate can improve the working stability of the boom plates, and markings can also be sprayed on the fixing plate to identify the lifting equipment of different types of rails for easy use.

[0032] like Figure 4 and 5 As shown, the anti-detachment mechanism structure of this embodiment is as follows: The anti-detachment mechanism 3 includes a guide rod 303, a cylinder 302, and a hook seat 306. The top of the cylinder 302 is fixed to the crossbeam sleeve 106 via a base 301. The upper part of the guide rod 303 is fitted inside the cylinder 302, and its bottom extends out of the cylinder 302 and is fixedly connected to the hook head 305. The hook seat 306 is fixed to the chain plate 8 sleeve via a fixing block. A rectangular groove is provided on the top surface of the hook seat 306 for the hook head 305 to pass through, and the hook head 305 is inserted into the hook seat 306 through the rectangular groove. The cylinder 302 is a cylindrical structure, with one end fixedly connected to the base 301 and the other end provided with a sealing plate 314. The guide rod 303 passes through the center of the sealing plate 314 and is inserted into the cylinder 302. To facilitate the rotation of the guide rod 303, a bearing is provided between the guide rod 303 and the sealing plate 314. The sealing plate 314 and the base 301 are respectively connected to the cylinder by bolts. In some other embodiments, the base 301 and the cylinder 302 can also be connected by welding. As long as the fixed connection between the base 301 and the cylinder 302 is met, there is no limitation on the connection method.

[0033] As an optional embodiment of this utility model, such as Figure 4 As shown, a movable locking block 309 is fixedly connected to the top of the guide rod 303. The movable locking block 309 slides up and down inside the cylinder 302 along with the guide rod 303, and the movable locking block 309 can rotate inside the cylinder 302. A fixed locking block 308 is provided above the movable locking block and is fixed inside the cylinder 302. In this embodiment, the fixed locking block 308 is fixed on the base 301. The end faces of the fixed locking block 308 and the movable locking block 309 are both provided with wave-shaped surfaces. The peaks and troughs of the wave-shaped surfaces on the fixed locking block 308 and the movable locking block 309 are formed by corresponding slides. A guide pin (not shown in the figure) is fixed on the cylinder 302. One end of the guide pin is connected to the side wall of the cylinder 302, and the other end extends into the slide, so that the guide rod moves along the trajectory of the slide.

[0034] In some embodiments, the fixing block 308 is fixed to the inner wall of the cylinder 302, such as by welding or bolts. Any connection method that can fix the fixing block 308 and the cylinder 302 can achieve the purpose of this example, and there is no limitation on the connection method between the two.

[0035] One section of the guide rod 303 has four planes 304 parallel to its axial direction on its outer periphery. In this embodiment, the lead screw plane 304 is located below the movable locking block 304. A pressure head 309 is provided on the outer side of two of the planes 304 that are arranged opposite to each other. The height of each of the four planes 304 is greater than the distance that the guide rod 303 moves linearly along the cylinder 302, so as to ensure that the pressure head 309 keeps in contact with the corresponding plane when the guide rod 303 moves up and down. The pressure head 309 is connected to the pressure cap 312 connected to the cylinder 302 through the pressure rod 311. One end of the pressure rod 311 is fixedly connected to the pressure head 309, and the other end is fitted into the pressure cap 312 and slidably connected to the pressure cap 312. An elastic element is fitted on the outer side of the pressure rod 311. In this embodiment, the elastic element is a spring. In other embodiments, other elastic elements, such as rubber elastic sleeves, can be used instead of springs. One end of the spring 310 is fixedly connected to the pressure head 309, and the other end is fixedly connected to the pressure cap 312, so that the pressure head 309 abuts against the corresponding plane 304 under the action of the spring 310. The two pressure heads 309 are arranged symmetrically about the axis of the guide rod 303. The symmetrical pressure heads 309 are not on the same straight line. Under the action of the spring 310, they provide elastic force to the guide rod 303, forming a torque, so that the guide rod cannot rotate in the opposite direction. The spring 310 in the compressed state has a certain preload. The symmetrical arrangement of the two springs 310 acts on the guide rod 310, forming a torque, so that the guide rod can only rotate counterclockwise and will not rotate in the opposite direction. This prevents the guide rod from rotating out of position due to wear on the working surfaces of the fixed block 308 and the movable block 309, and prevents the guide rod from reversing under external force. This ensures the stability of the lifting device during opening and closing, and ensures the safety of the lifting device during operation.

[0036] In other embodiments of this utility model (not shown in the figure), four planes 304 are provided on the part of the guide rod 303 extending above the fixing block 307. Correspondingly, the mounting hole 313 on the cylinder 302 is also provided on the upper part of the cylinder 302. At this time, there is a certain distance between the fixing block 307 and the base 301, so that the top of the guide rod 303 protrudes from the fixing block 307.

[0037] In this embodiment, the pressure cap 312 is connected to the cylinder 302 in the following way: two mounting holes 313 are provided on the cylinder 302, penetrating its side wall. The two mounting holes 313 are centrally symmetrical, with the center of symmetry being the axis of the guide rod 303. The mounting holes 313 are threaded holes, and the pressure cap 312 is threadedly connected to the mounting holes 313. The top of the pressure cap 312 is provided with an internal hexagon for easy assembly.

[0038] In order to improve the overall strength and rigidity of the rail lifting device of this utility model, a connecting sleeve is provided at the hinge point between the two side plates 10 and the toothed hook plate 9, and the two ends of the connecting sleeve are fixedly connected to the corresponding side plates 10 respectively.

[0039] To improve the ease of use of the rail lifting device of this utility model, a lifting hole 103 is provided on the crossbeam 1 of the lifting device, and a lifting ring is provided in the lifting hole 103.

[0040] This utility model of a rail lifting device comprises a lifting beam, an anti-derailment mechanism, a toothed hook plate, a fixing frame, chain plates, a lifting guide plate, pins, and sleeves. The overall structure is rationally designed and easy to manufacture. The lifting beam is connected to four arm plates and four chain plates via pins. An anti-derailment mechanism is installed between the upper and lower pins, adjusting the position of the chain plates and the large chain plate. During operation, the anti-derailment mechanism activates once for each lifting and lowering of the lifting beam, allowing the toothed hook plate to switch between locked and released states, ensuring high safety. It automatically completes the lifting and unloading of rails, is easy to operate, and enables simultaneous lifting of multiple rails without the need for additional binding procedures during the lifting process. The turnout rail lifting device of this utility model facilitates the lifting and transportation of rails, makes it easy to clamp the rails, and facilitates movement after clamping.
