[0030] In order to make the technical solutions and advantages in the embodiments of the present application clearer and more understandable, the following further details the exemplary embodiments of the present application with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0031] In this embodiment, the direction along the extension direction of the railway line is called the longitudinal direction (L direction in the figure), the horizontal direction perpendicular to the extension direction of the railway line is called the transverse direction (W direction in the figure), and the direction perpendicular to the horizontal plane is called the vertical or vertical direction (H direction).

[0032] Figure 1 It is a structural schematic diagram of a railway turnout laying and replacing operation vehicle provided by an embodiment of the present application. Figure 2 It is a top view of a railway turnout laying and replacing operation vehicle provided by an embodiment of the present application. As Figure 1 and Figure 2 shown, this embodiment provides a railway turnout laying and replacing operation vehicle, including: a longitudinal beam device 1, at least two groups of traveling devices 2, at least two groups of support devices 3, and at least two groups of rail lifting devices 4.

[0033] Among them, the longitudinal beam device 1 extends along the longitudinal direction, and its length can be set according to the length of the turnout.

[0034] At least two sets of traveling devices 2 are arranged at intervals longitudinally, each traveling device 2 straddles both sides of the longitudinal beam device 1, and the traveling device 2 can rotate horizontally relative to the longitudinal beam device 1.

[0035] At least two sets of support devices 3 are arranged at intervals longitudinally, each support device 3 straddles both sides of the longitudinal beam device 1. The support device 3 includes a support main body and a support base that can be lifted and lowered relative to the support main body. The support main body is connected to the longitudinal beam device, and the support base can be lowered to contact the ground. When the support base contacts the ground, it can support the longitudinal beam device 1 and can lift the longitudinal beam device 1 to a certain height.

[0036] At least two sets of rail lifting devices 3 are arranged at intervals longitudinally on the longitudinal beam device 1 for lifting and placing the switch.

[0037] During the laying process of the switch, first, use a transport vehicle to transport the above-mentioned track replacement operation vehicle to the construction site, lower the support device 3 to the ground, lift the operation vehicle to a certain height through the support device 3, then place the traveling device on the ground and lift the operation vehicle, and then retract the support device 3. The transport vehicle leaves the construction site. Then use a switch transport vehicle to transport the switch to the construction site. The operation vehicle moves above the switch transport vehicle through the traveling device 2, lifts the switch through the rail lifting device 4, and the switch transport vehicle leaves the construction site. Finally, the operation vehicle moves the switch to the specific laying and replacement position and adjusts the position of the switch by rotating the longitudinal beam device 1 to complete the laying and replacement of the switch.

[0038] The technical solution provided in this embodiment uses the traveling device to straddle both sides of the longitudinal beam device and can rotate horizontally with respect to the longitudinal beam device. The traveling device drives the operation vehicle to walk freely on the ground without being restricted by the track; the support device straddles both sides of the longitudinal beam device. The support device includes a support main body and a support base that can be lifted and lowered relative to the support main body. The support main body is connected to the longitudinal beam device, and the support base can be lowered to contact the ground, which can lift the whole operation vehicle to a certain height, facilitating the longitudinal beam device to rotate a certain angle to adjust the position of the switch; the rail lifting device is arranged at intervals along the length direction of the longitudinal beam device on the longitudinal beam device for lifting and placing the switch. The above-mentioned operation vehicle can flexibly lift and place, move, and rotate the switch, adjust the position of the switch, and quickly lay the switch.

[0039] The above-mentioned traveling device 2 can not only rotate relative to the longitudinal beam device 1, but also move horizontally and vertically relative to the longitudinal beam device 1. In this embodiment, two longitudinal beam devices 1 are taken as an example to elaborate on the implementation manner of the operation vehicle. On the basis of the above technical solution, this embodiment provides a specific implementation manner of the traveling device 2:

[0040] The traveling device includes: a turntable, a first transverse sliding sleeve, a first transverse sliding beam, a first vertical telescopic mechanism, and a crawler traveling mechanism. Among them, the turntable is arranged on the top of the longitudinal beam device. The first transverse sliding sleeve is connected to the turntable and rotates horizontally relative to the longitudinal beam device through the turntable. One end of the first transverse sliding beam is telescopically inserted into the first transverse sliding sleeve. The top of the first vertical telescopic mechanism is connected to the other end of the first transverse sliding beam. The crawler traveling mechanism is connected to the bottom end of the first vertical telescopic mechanism and can rotate horizontally relative to the first vertical telescopic mechanism.

[0041] Figure 3 This is a schematic structural diagram of the traveling device and the rail lifting device in the railway switch laying and replacement operation vehicle provided by the embodiment of the present application. As Figures 1 to 3 shown, a specific implementation: The traveling device 2 includes: a turntable 21, a first transverse sliding sleeve 22, a first transverse sliding beam 23, a first pillar sliding sleeve 24, a first pillar sliding beam, a slewing bearing 25, and a crawler traveling mechanism 26. Among them, the turntable 21 is arranged on the top of the longitudinal beam device 1, specifically at the position in the middle of the two longitudinal beam devices 1. The turntable 21 includes a fixed part and a rotating part. The fixed part is fixed on the longitudinal beam device 1, and the rotating part can rotate relative to the fixed part.

[0042] The first transverse sliding sleeve 22 is connected to the turntable 21 and rotates horizontally relative to the longitudinal beam device 1 through the turntable. Specifically, the first transverse sliding sleeve 22 is a cylindrical structure with a rectangular cross-section, extends in the horizontal direction, and is fixed to the rotating part of the turntable 21.

[0043] The first transverse sliding beam 23 extends in the horizontal direction, and one end of it is telescopically inserted into the first transverse sliding sleeve 22. The first pillar sliding sleeve 24 is connected to the other end of the first transverse sliding beam 23 and moves synchronously with the first transverse sliding beam 23. The first pillar sliding sleeve 24 is a cylindrical structure with a rectangular cross-section and extends in the vertical direction.

[0044] The first pillar sliding beam extends in the vertical direction, and its top end is telescopically inserted into the first pillar sliding sleeve 24. The slewing bearing 25 is arranged at the bottom end of the first pillar sliding beam. The slewing bearing 25 includes two rotating parts that rotate relative to each other. The bottom end of the first pillar sliding beam is connected to one of the rotating parts, and the crawler traveling mechanism is connected to the other rotating part to realize the horizontal rotation of the crawler traveling mechanism relative to the first pillar sliding beam.

[0045] The above-mentioned first pillar sliding sleeve 24 and the first pillar sliding beam can form the above-mentioned first vertical telescopic mechanism, also called a first-level vertical telescopic structure, or can also form a two-level vertical telescopic member structure. When the first pillar sliding beam is a beam-like structure, a first-level vertical telescopic structure is formed. Or the following scheme is adopted to form a two-level vertical telescopic structure:

[0046] As Figure 3As shown in the figure, the first pillar sliding beam includes: a secondary pillar sliding sleeve 27 and a secondary pillar sliding beam 28. Among them, the top end of the secondary pillar sliding sleeve 27 is telescopically inserted into the first pillar sliding sleeve 24. The secondary pillar sliding sleeve 27 is a cylindrical structure with a rectangular cross-section and extends in the vertical direction. The secondary pillar sliding beam 28 extends vertically, and its top end is telescopically inserted into the secondary pillar sliding sleeve 27, and its bottom end is connected to the rotating part of the slewing bearing, so that the crawler traveling mechanism can rotate horizontally relative to the secondary pillar sliding beam 28. The two-stage telescopic solution can reduce the volume of the traveling device and save the occupied space.

[0047] Furthermore, a slewing locking cylinder 29 is connected between the longitudinal beam device 1 and the traveling device 2. When the supporting device 3 props up the work vehicle to make it in an unloaded state, the slewing locking cylinder 29 is used to limit the relative rotation between the longitudinal beam device 1 and the traveling device 2, so that the two remain relatively fixed and prevent the longitudinal beam device and the traveling device 2 from rotating randomly when unloaded.

[0048] This embodiment provides an implementation manner of the longitudinal beam device: As Figure 1 and Figure 2 shown in the figure, the longitudinal beam device includes: a longitudinal beam 11 and a telescopic beam 12. Among them, the longitudinal beam 11 extends in the longitudinal direction, and a cavity is provided at its end. The longitudinal beam 11 can specifically be a box girder with a rectangular cross-section. The number of longitudinal beams 11 is two, and the two longitudinal beams 11 are arranged side by side with a preset distance left between them, and the two longitudinal beams 11 are connected together through a transverse connection structure. There can be multiple transverse connection structures, which are respectively arranged at different positions of the longitudinal beam 11. The above-mentioned turntable 21 can specifically be arranged on the transverse connection structure.

[0049] The telescopic beam 12 extends longitudinally. One end of it is telescopically inserted into the cavity at the end of the longitudinal beam 11, and the other end can be provided with a rail lifting device 4. By setting the telescopic beam 12, the length of the longitudinal beam device can be adjusted to lay turnouts of different lengths. When the telescopic beam 12 extends to the longest, the overall length of the work vehicle can reach 32 meters.

[0050] Of course, another implementation manner of the longitudinal beam device is: only including the longitudinal beam 11, and the rail lifting device is arranged on the longitudinal beam 11.

[0051] This embodiment also provides an implementation manner of the rail lifting device 4: As Figure 3 shown in the figure, the rail lifting device 4 includes: a main beam 41 and a rail lifting hook 42. The main beam 41 extends in the transverse direction and is connected to the longitudinal beam device 1 through a lifting oil cylinder 43. The lifting oil cylinder 43 can drive the main beam 41 to move up and down. The rail lifting hook 42 can slide along the main beam 41, and the number of them can be two, which are used to lift the turnout from the transverse sides.

[0052] This embodiment provides a specific implementation: the main beam 41 is an I-beam, including a top plate, a bottom plate extending in the horizontal direction, and a web vertically connected between the middle parts of the top plate and the bottom plate. The top of the rail lifting hook 42 can slide along both sides of the bottom plate.

[0053] Figure 4 It is a schematic structural diagram of the butt joint between the extension beam and the main beam of the rail lifting device in the railway turnout laying and replacement operation vehicle provided by the embodiment of the present application. As Figure 3 and Figure 4 shown, further, the rail lifting device 4 further includes: an extension beam 44, and the extension beam 44 is connected to the main beam 41 through a hinge mechanism 45, so that the extension beam 44 can rotate relative to the main beam 41. The hinge mechanism 45 may include at least two hinge members, and is connected between the main beam 41 and the extension beam 44 in a hinged manner. When the length of the main beam 41 meets the turnout requirements, the extension beam 44 is stored above the main beam 41, and the rail lifting hook 42 slides on the main beam 41 to lift the turnout; when the length of the main beam 41 cannot meet the turnout requirements, the extension beam 44 is lowered and butted at the end of the main beam 41 (as Figure 4 shown), and the rail lifting hook 42 can slide on the main beam 41 and the extension beam 44, increasing the distance between the two rail lifting hooks 42. The number of extension beams 44 can be two, symmetrically arranged on the main beam 41.

[0054] The extension beam 44 can also be an I-beam, so that the rail lifting hook 42 can reciprocate on the main beam 41 and the extension beam 44. The extension beam 44 includes: a top plate, a bottom plate extending in the horizontal direction, and a web vertically connected between the middle parts of the top plate and the bottom plate; the bottom plate of the extension beam is butted against the bottom plate of the main beam, and the top of the rail lifting hook slides along both sides of the bottom plate of the extension beam.

[0055] The operation vehicle can be provided with six groups of rail lifting devices 4, which are arranged at intervals in the longitudinal direction, and lift the turnout from multiple positions, which can effectively prevent the turnout from deforming during the lifting process.

[0056] The function of the above-mentioned support device 3 is to support on the ground and lift the whole operation vehicle to a certain height. This embodiment provides a specific implementation of the support device 3: the support device 3 includes: a support main body and a support base, wherein the support main body includes a second transverse sliding sleeve 31, a second transverse sliding beam 32, a second pillar sliding sleeve 33 and a support base 34. Among them, the second transverse sliding sleeve 31 is arranged on the top of the longitudinal beam device 1, specifically on the top of the longitudinal beam 11. The second transverse sliding sleeve 31 is a cylindrical structure with a rectangular cross-section and extends in the transverse direction.

[0057] The second transverse sliding beam 32 extends in the transverse direction, and one end of it is telescopically inserted into the second transverse sliding sleeve 31. The second pillar sliding sleeve 33 is connected to the other end of the second transverse sliding beam 32. The second pillar sliding sleeve 33 is a cylindrical structure with a rectangular cross-section and extends vertically. A support column can be arranged at the top of the support base 34, and the support column is telescopically inserted into the second pillar sliding sleeve 33. The telescoping of the second transverse sliding beam 32 enables the support device 3 to telescopically move horizontally, and the telescoping of the support base 34 enables it to move up and down.

[0058] The telescoping of the support device 3 can be achieved by a hydraulic drive method. The support device 3 can adopt single-stage vertical telescoping or two-stage vertical telescoping, and specifically can be set with reference to the above-mentioned traveling device.

[0059] Figure 5 It is a schematic diagram of the railway turnout laying and replacement operation vehicle provided by the embodiment of the present application in the transportation state. Figure 6 is Figure 5 the enlarged view of area A in Figure 5 and Figure 6 As shown in

[0060] As shown in Figure 5 shown, further, a longitudinal sliding seat 35 and a longitudinal drive mechanism 36 can be arranged on the top of the longitudinal beam device 1. Among them, the longitudinal sliding seat 35 is slidably connected to the second transverse sliding sleeve 31 in the support device 3, and the second transverse sliding sleeve 31 can move longitudinally relative to the longitudinal sliding seat 35. The longitudinal drive mechanism 36 is used to drive the second transverse sliding sleeve 31 to move longitudinally, so as to adjust the longitudinal position of the support device 3, adjust the center of gravity and balance of the operation vehicle, and also facilitate the accurate alignment of the turnout.

[0060] As shown in Figure 5 shown, the turnout laying and replacement operation vehicle is transported to the construction site by the flatbed truck 5. During the transportation process, the traveling device 2 and the support device 3 are both lifted and retracted, and the fixed seats 13 at both ends of the longitudinal beam device are downwardly abutted against the surface of the flatbed truck 5 for fixing the operation vehicle. The fixed seat 13 can be a hydraulic drive mechanism.

[0061] Figure 7 It is a schematic diagram of the railway turnout laying and replacement operation vehicle getting off provided by the embodiment of the present application. As shown in Figure 7 shown, when the flatbed truck 5 transports the operation vehicle to the construction site, the fixed seat 13 is opened, the support device 3 is horizontally expanded and lowered to the ground. After the operation vehicle is lifted to a certain height, the traveling device 2 is horizontally expanded and vertically moved to the ground to support the operation vehicle. Then the support device 3 is raised and horizontally retracted. The flatbed truck 5 leaves the site to complete the unloading operation of the operation vehicle.

[0062] Figure 8 It is a schematic diagram of the railway turnout laying and replacement operation vehicle lifting and lowering the turnout on the turnout transport vehicle provided by the embodiment of the present application. As shown in Figure 8As shown in the figure, the turnout transporter 6 transports the turnout 7 to the laying site. The working vehicle moves above the turnout transporter 6 through the traveling device 2, specifically spanning above the turnout transporter 6. Then, the turnout is lifted by the rail-lifting device 4, and the turnout transporter 6 leaves the site. The working vehicle moves with the turnout to the laying position, can move horizontally and longitudinally, and the longitudinal beam 11 can rotate relative to the traveling device to adjust the position and angle of the turnout for laying construction.

[0063] The working vehicle provided in this embodiment adopts the longitudinal beam device 1, the traveling device 2, the supporting device 3, and the rail-lifting device 4 to realize functions such as short-distance transportation, loading and unloading, lateral movement, lifting, and rotation of the turnout, with high flexibility, and has the characteristics of convenient transfer, strong single-machine lifting capacity, and accurate alignment of the turnout laying and replacement, aiming to solve the construction pain points of the turnout laying and replacement.

[0064] When the working vehicle is traveling, the swing locking cylinder 29 becomes in a floating state, then the longitudinal beam 11 and the traveling device 2 can freely rotate according to the steering needs; when the supporting device 3 supports the working vehicle and the traveling device 2 is in an unloaded state, the swing locking cylinder 29 is locked to prevent the traveling device 2 and the longitudinal beam 11 from rotating randomly.

[0065] The above-mentioned traveling device 2 adopts a crawler traveling mechanism 26, which can travel on the ground without being restricted by tracks. Moreover, the crawler traveling mechanism 26 can rotate in the horizontal direction, improving the flexibility of the working vehicle. The distance between the two crawler traveling mechanisms 26 can be set according to the width of the turnout, for example: 10 m. The crawler traveling mechanism 26 can move laterally to avoid obstacles and bypass obstacles on the ground.

[0066] A dual-power system 8 and a hydraulic system 9 that provide power for the working vehicle are arranged on the longitudinal beam 11. The two sets of power transmission systems are arranged side by side in the middle position of the longitudinal beam 11 and share an engine room, and one of the power systems can be used for rescue.

[0067] This embodiment also provides a turnout laying and replacement operation system, including: the above-mentioned railway turnout laying and replacement working vehicle, a flatbed vehicle for transporting the railway turnout laying and replacement working vehicle, and a turnout transporter for transporting the turnout, which jointly complete the turnout laying operation.
