[0002] A turnout is the assembly of connection and crossing equipment between lines. It is an important part of the railway crossing and also the weakest part of the line. Railway turnouts have the characteristics of large quantity, complex structure, short service life, limited vehicle speed, large maintenance workload, low driving safety, heavy rails and sleepers on the line. Therefore, replacing turnouts on railway lines is a task with huge workload. And the current development trend is to use mechanization to realize the laying and replacement of turnouts. According to the analysis of existing technologies at home and abroad, the current turnout laying and replacement equipment mainly includes the following types:

[0004] 2. Through the joint operation of multiple groups of upper computers and lower computers. This method requires pre-laying process tracks and also needs to be equipped with a special crane to unload the upper computer from the transport vehicle. The labor demand is large, the organization of construction is difficult, the process is relatively complex, and it is not conducive to improving the operation efficiency.

[0005] 3. The turnout laying machine transports turnouts by hoisting.

[0006] In short, the difficulties in transporting turnout materials, the large construction difficulty of manual cooperation with mechanical operation, the high safety risk, the difficulty in lifting long turnouts, the inflexible installation, and the easy serious deformation of turnouts are all problems that need to be solved urgently at present.

[0042] Embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. Although some embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided to more thoroughly and completely understand the present utility model. It should be understood that the drawings and embodiments of the present utility model are only for exemplary purposes and are not used to limit the protection scope of the present utility model.

[0043] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0044] In this embodiment, as Figure 1 and Figure 2 shown, a special hoisting tool for turnouts includes a hoisting frame 1, an inner frame 2, hoisting balance ropes 3, lifting lugs 5, a hoisting device 6, a lower lifting lug 7, and a hoisting ring buckle 8. The hoisting frame 1 is a trapezoidal structure adapted to the turnout structure. The trapezoidal structure is adapted to the turnout structure and can closely fit the shape of the turnout, so that during the hoisting process, the contact between the hoisting frame and the turnout is more sufficient and stable.

[0045] The number of the lifting lugs 5 and the hoisting balance ropes 3 is four each. The four lifting lugs 5 are respectively welded at the four corners of the trapezoidal structure, and one end of each of the four lifting lugs 5 is welded to the hoisting frame 1. The other ends of the four lifting lugs 5 are respectively shackle-connected to one end of the corresponding hoisting balance ropes 3. The other ends of the four hoisting balance ropes 3 are all shackle-connected to the hoisting ring buckle 8. During the hoisting process, the four lifting lugs 5 jointly bear the weight of the turnout, so that the turnout can be lifted smoothly. This helps to keep the turnout in a horizontal state during the hoisting process, prevent the turnout from tilting or shaking, and improve the safety and stability of the hoisting.

[0046] Further, more lifting lugs 5 and hoisting balance ropes 3 can also be added on the basis of the four lifting lugs 5 to share the weight of the turnout with more lifting lugs 5 and hoisting balance ropes 3.

[0047] The inner frame 2 is arranged inside the hoisting frame 1, and both ends of the inner frame 2 are welded to the two waists of the trapezoidal structure, providing additional support for the hoisting frame 1. This support can effectively prevent the hoisting frame 1 from deforming when bearing the weight of the turnout or being affected by external forces, and enhance the stability of the entire hoisting structure. One end of the lower lifting lug 7 is welded to the inner frame 2. The hoisting device 6 is shackle-connected below the lower lifting lug 7, and the other end of the hoisting device 6 is used to connect the turnout to be hoisted. The hoisting device 6, as a key component connecting the turnout to be hoisted and the hoisting structure, ensures that the turnout can be firmly connected to the entire hoisting tool. Through cooperation with the lower lifting lug 7, the force bearing from the hoisting frame 1 and the inner frame 2 to the turnout is realized, providing a reliable way for the hoisting of the turnout.

[0048] As Figure 1 shown, in this embodiment, the inner frame 2 includes a first inner frame 21 and a second inner frame 22. The first inner frame 21 is welded to one side of the lifting frame 1 close to the upper base of the trapezoidal structure, and the second inner frame 22 is welded to one side of the lifting frame 1 close to the lower base of the trapezoidal structure. During the lifting process, the turnout may tilt due to unstable center of gravity or external force. The first inner frame 21 and the second inner frame 22 can respectively restrain the turnout to be lifted from the head end and the tail end, prevent the turnout to be lifted from tilting at a large angle, and ensure that the turnout always remains in a relatively stable position.

[0049] As Figure 1 shown, in this embodiment, the lifting frame 1 includes a first lifting rod 11, a second lifting rod 12, a third lifting rod 13 and a fourth lifting rod 14. One end of the first lifting rod 11 is welded to one end of the second lifting rod 12, the other end of the second lifting rod 12 is welded to one end of the third lifting rod 13, the other end of the third lifting rod 13 is welded to one end of the fourth lifting rod 14, and the other end of the fourth lifting rod 14 is welded to the other end of the first lifting rod 11, thereby constructing a specific trapezoidal structure.

[0050] As Figure 1 shown, in this embodiment, the lower lifting lug 7 includes a first lower lifting lug 71 and a second lower lifting lug 72. The number of the first lower lifting lugs 71 is six, and the six first lower lifting lugs 71 are welded to the lower surface of the first inner frame 21 according to the lifting points of turnouts with different specifications. The number of the second lower lifting lugs 72 is six, and the six second lower lifting lugs 72 are welded to the lower surface of the second inner frame 22 according to the lifting points of turnouts with different specifications. When setting the position of the lower lifting lug 7, first perform a finite element analysis on turnouts to be lifted with different specifications to obtain the center of gravity positions of multiple turnouts, and then set multiple lifting lugs on the lower surface of the inner frame according to the center of gravity positions of multiple turnouts. During the lifting operation, select the corresponding lower lifting lug for lifting according to the center of gravity of the specific turnout to be lifted.

[0051] As Figure 1 shown, in this embodiment, the number of the lifting devices 6 is multiple, and the multiple lifting devices 6 are respectively shackle-connected to the corresponding lower lifting lugs 7, thereby completing the lifting work.

[0052] As Figure 3 and Figure 4 shown, in this embodiment, the lifting device 6 includes a wire rope assembly 61, a U-shaped shackle 62, a shackle bolt 63, an ear plate 64 and a lifting tong mechanism 65;

[0053] One end of the wire rope assembly 61 is connected to the lower lifting lug 7, and the other end of the wire rope assembly 61 is connected to the U-shaped shackle 62; the U-shaped shackle 62 is connected to the ear plate 64 through a shackle bolt 63. As a commonly used connecting element, the U-shaped shackle 62 can be conveniently connected to and disassembled from other components. The ear plate 64 is welded to the upper surface of the tong mechanism 65. As an interface for connecting the tong mechanism 65, the ear plate 64 can bear the force from the tong mechanism 65 and transmit it to the wire rope assembly 61;

[0054] The tong mechanism 65 includes a tong body 651, a curved surface groove 652, adjustment holes 653 and adjustment bolts 654;

[0055] The tong body 651 includes a vertical portion 6511 and a horizontal portion 6512. The number of the vertical portions 6511 is two, and the two vertical portions 6511 are perpendicular to the lower surface of the horizontal portion 6512; the number of the curved surface grooves 652 is two, and the two curved surface grooves 652 are respectively arranged at one end of the two vertical portions 6511 away from the ear plate 64 and are adapted to the rail bottom; the number of the adjustment holes 653 is 2, and the two adjustment holes 653 are respectively arranged at one end of the two vertical portions 6511 close to the ear plate 64. The number of the adjustment bolts 654 is two, and the two adjustment bolts 654 are respectively threadedly connected to the adjustment holes 653 and are used to be inserted into the rail web. When facing turnouts with different rail web thicknesses, the position of the adjustment bolts 654 in the adjustment holes 653 can be adjusted to achieve tight insertion into the rail web, improving the versatility and adaptability of the tong body 651.

[0056] Overall, the tong body 651 can fit the shape of the turnout. Through the adaptation of the curved surface groove 652 to the rail bottom and the insertion of the adjustment bolts 654 into the rail web, the tong body 651 can firmly grip the turnout, ensuring that the turnout will not loosen or fall off during the hoisting process.

[0057] The wire rope assembly 61 includes a wire rope 611 and wire rope clamps 612. The wire rope clamps 612 are arranged at both ends of the wire rope 611 and are used to fix the wire rope 611.

[0058] In this embodiment, as Figure 1 shown, the hoisting tool further includes a reinforcing rod 4. The reinforcing rod 4 includes a first reinforcing rod 41 and a second reinforcing rod 42, and the first reinforcing rod 41 and the second reinforcing rod 42 are in a cross shape; the cross arrangement of the reinforcing rod 4 can make the force on the hoisting tool more uniform. By dispersing the force to different directions and positions, the situation of excessive local force is reduced, and the risk of fatigue damage of the hoisting tool is lowered. At the same time, the balanced force distribution also helps to improve the hoisting accuracy and safety.

[0059] The lower surface of one end of the first reinforcing rod 41 is welded to the upper surface of one end of the first inner frame 21, and the lower surface of the other end of the first reinforcing rod 41 is welded to the upper surface of one end of the second inner frame 22, effectively preventing one end of the first inner frame 21 and one end of the second inner frame 22 from deforming or twisting due to the weight of the switch.

[0060] The upper surface of one end of the second reinforcing rod 42 is welded to the lower surface of the other end of the first inner frame 21, and the upper surface of the other end of the second reinforcing rod 42 is welded to the lower surface of the other end of the second inner frame 22; effectively preventing the other end of the first inner frame 21 and the other end of the second inner frame 22 from deforming or twisting due to the weight of the switch.

[0061] During operation, the curved groove 652 of the lifting tong mechanism 65 is fitted to the bottom of the rail of the switch. According to the rail waist thickness of the switch to be lifted, the position of the adjusting bolt 654 in the adjusting hole 653 in the lifting tong mechanism 65 is correspondingly adjusted to achieve tight clamping of the rail waist and firmly grip the switch. Then, the entire lifting tool and the switch are lifted together by connecting the four lifting lugs 5 on the lifting frame 1 through a lifting device; during the lifting process, the first inner frame 21 and the second inner frame 22 are arranged in a trapezoidal lifting frame adapted to the switch structure, respectively close to one side of the upper base and the lower base of the trapezoidal structure, and connected to the waist of the trapezoidal structure. They closely fit the switch, provide a stable support base for the switch, adapt to the shape of the switch while sharing part of the weight of the switch and evenly distributing it on the lifting tool. One end of the lower lifting lug 7 is connected to the inner frame 2, providing a clear connection point for the lifting device 6 to achieve force transmission, and at the same time playing a role of positioning and guiding to ensure that the lifting device 6 can be accurately connected to the inner frame 2. One end of the wire rope assembly 61 of the lifting device 6 is connected to the lower lifting lug 7, and the other end is connected to the U-shaped shackle 62, and the force on the lifting tong mechanism 65 is transmitted to the inner frame 2 through the wire rope assembly 61 by the shackle bolt 63 and the ear plate 64. During the lifting process, the lifting device transmits the weight of the switch to the inner frame 2 and the lifting frame 1 through the lower lifting lug 7, and can be adjusted according to the specific situation of the switch. For example, the length of the wire rope assembly can adapt to different lifting devices and working environments, and the adjusting bolt 654 on the lifting tong mechanism 65 can be adjusted according to the rail waist size of the switch to firmly grip the switch. The reinforcing rod 4 includes a first reinforcing rod 41 and a second reinforcing rod 42, which are cross-connected to the inner frame 2 so that the reinforcing rod 4 provides additional support force for the inner frame 2 in the horizontal and vertical directions, preventing the inner frame 2 from deforming or twisting during the lifting process. The cross-shaped structure can effectively disperse stress and improve the stability of the entire lifting structure. At the same time, the reinforcing rod 4 works together with components such as the inner frame 2, the lower lifting lug 7, and the lifting device 6 to jointly bear the weight of the switch and the external force during the lifting process, coordinate the force on each component, ensure uniform and stable force transmission, prevent local overloading and damage, and ensure that the switch remains stable without tilting, shaking or falling off.

[0062] The above are only the preferred embodiments of the present utility model, and do not impose any limitations on the present utility model. Any simple modifications, changes, and equivalent structural transformations made to the above embodiments according to the technical essence of the present utility model still fall within the scope of protection of the technical solution of the present utility model.
