[0034] In order to make the technical solutions and advantages in the embodiments of the present application clearer and more understandable, the exemplary embodiments of the present application will be further described in detail below 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.

[0035] In this embodiment, the direction along the extension of the railway line is called the longitudinal direction (the L direction in the figure), the horizontal direction perpendicular to the extension direction of the railway line is called the transverse direction (the W direction in the figure), and the direction perpendicular to the horizontal plane is called the vertical or vertical direction (the H direction).

[0036] Figure 1 It is a schematic structural diagram of a railway switch laying and replacing operation vehicle provided by an embodiment of the present application. Figure 2 It is a top view of a railway switch laying and replacing operation vehicle provided by an embodiment of the present application. Figure 1 , Figure 3 It is a top view of a railway switch laying and replacing operation vehicle provided by an embodiment of the present application. Figure 2 . As Figures 1 to 3 shown, this embodiment provides a railway switch laying and replacing operation vehicle, including: a longitudinal beam device 1, at least two groups of traveling devices 2, at least two groups of supporting devices 3, and at least two groups of rail lifting devices 4.

[0037] Among them, the longitudinal beam device 1 extends along the longitudinal direction, and its length can be set according to the length of the switch. The longitudinal beam device 1 includes a main longitudinal beam part and a telescopic longitudinal beam part arranged at the longitudinal end of the main longitudinal beam part. The telescopic longitudinal beam part can telescopically move along the longitudinal direction with respect to the main longitudinal beam part, so that the overall length of the longitudinal beam device 1 is adjustable. One implementation method: a telescopic longitudinal beam part is arranged at one end of the main longitudinal beam part, or telescopic longitudinal beam parts are arranged at both ends of the main longitudinal beam part.

[0038] Furthermore, it further includes a telescopic beam. The telescopic beam extends longitudinally, and one end of it is telescopically connected to the end of the main longitudinal beam part and / or telescopically connected to the end of the telescopic longitudinal beam part.

[0039] At least two groups of running devices 2 are arranged at intervals along the longitudinal direction, and each running device 2 spans across the two sides of the longitudinal beam device 1. The running devices 2 can rotate horizontally relative to the longitudinal beam device 1 (such as the R direction in the figure). At least one group of running devices 2 is arranged on the telescopic longitudinal beam portion. One implementation method: Assuming that the number of running devices 2 is two, one running device 2 is arranged on the main longitudinal beam portion, and the other running device 2 is arranged on the telescopic longitudinal beam portion. By adjusting the length of the telescopic longitudinal beam portion relative to the main longitudinal beam portion, the longitudinal distance between the two running devices 2 can be adjusted. Another implementation method: When the telescopic longitudinal beam portions are arranged at both ends of the main longitudinal beam portion, the two running devices 2 are respectively arranged on the telescopic longitudinal beam portions. By adjusting the length of the two telescopic longitudinal beam portions relative to the main longitudinal beam portion, the longitudinal distance between the two running devices 2 can be adjusted.

[0040] At least two groups of support devices 3 are arranged at intervals along the longitudinal direction, and each support device 3 spans across the two sides of the longitudinal beam device 1. The support device 3 includes a support body and a support base that can be raised and lowered relative to the support body. The support body is connected to the longitudinal beam device, and the support base can be lowered to contact the ground. When the support base is in contact with the ground, the longitudinal beam device 1 can be supported and can be lifted to a certain height. At least one group of support devices 3 is arranged on the telescopic longitudinal beam portion. Referring to the arrangement of the above-mentioned running device 2, it is assumed that the number of support devices 3 is two groups, one of which is arranged on the main longitudinal beam portion, and the other is arranged on the telescopic longitudinal beam portion; or the two groups of support devices 3 are respectively arranged on the telescopic longitudinal beam portions at both ends of the main longitudinal beam portion.

[0041] At least two groups of rail lifting devices 3 are arranged at intervals in the longitudinal direction for hanging and placing the turnout. The number of rail lifting devices 3 can be multiple, and can be arranged on the main longitudinal beam portion, can also be arranged on the telescopic longitudinal beam portion, and can also be arranged on the telescopic beam.

[0042] During the laying process of the turnout, firstly, the above-mentioned laying and replacement work vehicle is transported to the construction site by a transport vehicle, and the support device 3 is lowered to the ground. After the work vehicle is supported to a certain height by the support device 3, the running device is lowered to the ground and the work vehicle is supported, and then the support device 3 is folded. The transport vehicle leaves the construction site. Then, the turnout transport vehicle is used to transport the turnout to the construction site, and the work vehicle is moved to the top of the turnout transport vehicle by the running device 2, and the turnout is lifted by the rail lifting device 4, and the turnout transport vehicle leaves the construction site. Finally, the work vehicle moves the turnout to the specific laying and replacement position, and adjusts the turnout position by rotating the longitudinal beam device 1 to complete the laying and replacement of the turnout.

[0043] In the above process, adjust the elongation dimension of the telescopic longitudinal beam part relative to the main body longitudinal beam part, and adjust the distances between the support devices 3 and between the traveling devices 2 to adapt to the length of the turnout, ensure the stability of the working vehicle, and keep the turnout balanced during the lifting process.

[0044] Figure 2 It is a view of the telescopic longitudinal beam part contracting relative to the main body longitudinal beam part. Figure 3 It is a view of the telescopic longitudinal beam part extending relative to the main body longitudinal beam part.

[0045] The technical solution provided in this embodiment adopts the traveling devices straddling both sides of the longitudinal beam device, which can rotate horizontally with the longitudinal beam device. The working vehicle is driven by the traveling devices to move freely on the ground without being restricted by the track. The support devices straddle both sides of the longitudinal beam device. The support device includes a support main body and a support base that can be lifted 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, and the whole working vehicle can be lifted to a certain height, which is convenient for the longitudinal beam device to rotate by a certain angle to adjust the position of the turnout. The rail lifting devices are arranged on the longitudinal beam device at intervals along the length direction of the longitudinal beam device and are used for lifting and lowering the turnout. The above working vehicle can flexibly lift, move, and rotate the turnout, adjust the position of the turnout, and quickly lay the turnout. In addition, the longitudinal beam device includes a main body longitudinal beam part and a telescopic longitudinal beam part. The telescopic longitudinal beam part can extend or contract longitudinally relative to the main body longitudinal beam part. At least one traveling device is arranged on the telescopic longitudinal beam part, and at least one support device is arranged on the telescopic longitudinal beam part. By adjusting the length of the longitudinal beam part extending relative to the main body longitudinal beam part, the distances between the traveling devices and between the support devices can be adjusted to adapt to turnouts of different lengths, so that the turnout remains balanced and stable during the lifting process.

[0046] On the basis of the above technical solution, this embodiment provides an implementation manner of the longitudinal beam device 1:

[0047] Figure 4 It is a top view of the longitudinal beam device in the railway turnout laying and replacing working vehicle provided by the embodiment of the present application. Figure 1 , Figure 5 It is a top view of the longitudinal beam device in the railway turnout laying and replacing working vehicle provided by the embodiment of the present application. Figure 2 . Figure 4 It shows a view of the telescopic longitudinal beam part in the longitudinal beam device contracting relative to the main body longitudinal beam part. Figure 5 It shows a view of the telescopic longitudinal beam part extending relative to the main body longitudinal beam part.

[0048] Such as Figure 4 and Figure 5As shown, the main longitudinal beam portion includes: two longitudinal beams 11 arranged side by side, with a preset spacing left between the two longitudinal beams 11, and the two longitudinal beams 11 are connected by a transverse connection structure 15. There can be multiple transverse connection structures 15, which are respectively arranged at different positions of the longitudinal beam 11. The transverse connection structure is specifically a cross beam.

[0049] The longitudinal beam 11 can specifically be a box beam with a rectangular cross-section, and there is a cavity at the end. The telescopic longitudinal beam portion includes two sub-longitudinal beams 14, and the two sub-longitudinal beams 14 are arranged side by side. One sub-longitudinal beam 14 is slidably inserted into the cavity at the end of one longitudinal beam 11. The two sub-longitudinal beams 14 are also connected by a cross beam connection structure 15.

[0050] Another implementation method: The longitudinal beam 11 and the sub-longitudinal beam 14 are arranged side by side and penetrate into the same sleeve. The sleeve is fixedly connected to the longitudinal beam 11, and the sub-longitudinal beam 14 telescopically moves relative to the sleeve.

[0051] One end of the telescopic beam 12 is telescopically inserted into the cavity at the end of the longitudinal beam 11 and / or the cavity at the end of the sub-longitudinal beam 14, 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 1 can be further adjusted to lay turnouts of different lengths. When the telescopic beam 12 extends to the longest, the overall length of the working vehicle can reach 36 meters.

[0052] In this embodiment Figure 4 and Figure 5 The shown solution: The right end of the longitudinal beam 11 is slidably connected to the sub-longitudinal beam 14, and the right end of the sub-longitudinal beam 14 is slidably connected to the telescopic beam 12. The left end of the longitudinal beam 11 is slidably connected to the telescopic beam 12.

[0053] The above 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 examples to elaborate on the implementation method of the working vehicle. On the basis of the above technical solution, this embodiment provides a specific implementation method of the traveling device 2:

[0054] The traveling device includes: a turntable, a first transverse translation sleeve, a first transverse translation 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 1. The first transverse translation sleeve is connected to the turntable and rotates horizontally relative to the longitudinal beam device 1 through the turntable. One end of the first transverse translation beam is telescopically inserted into the first transverse translation sleeve. The top of the first vertical telescopic mechanism is connected to the other end of the first transverse translation 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.

[0055] Figure 6 It is a schematic structural diagram of the traveling device and the rail lifting device in the railway turnout laying and replacement working vehicle provided by the embodiment of the present application. As Figure 6As shown in the figure, 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 support sliding sleeve 24, a first support 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 between 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 can be specifically arranged on the transverse connection structure 15. The rotating part can rotate relative to the fixed part.

[0056] 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 horizontally, and is fixed to the rotating part of the turntable 21.

[0057] The first transverse sliding beam 23 extends horizontally, and one end of it is telescopically inserted into the first transverse sliding sleeve 22. The first support 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 support sliding sleeve 24 is a cylindrical structure with a rectangular cross-section and extends vertically.

[0058] The first support sliding beam extends vertically, and its top end is telescopically inserted into the first support sliding sleeve 24. The slewing bearing 25 is arranged at the bottom end of the first support sliding beam. The slewing bearing 25 includes two relatively rotating rotating parts. The bottom end of the first support 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 support sliding beam.

[0059] The above-mentioned first support sliding sleeve 24 and the first support sliding beam can form the above-mentioned first vertical telescopic mechanism, also called a primary vertical telescopic structure, or can also form a two-stage vertical telescopic member structure. When the first support sliding beam is a beam-like structure, a primary vertical telescopic structure is formed. Or the following scheme is adopted to form a two-stage vertical telescopic structure:

[0060] As Figure 6 shown, the first support sliding beam includes: a secondary support sliding sleeve 27 and a secondary support sliding beam 28. Among them, the top end of the secondary support sliding sleeve 27 is telescopically inserted into the first support sliding sleeve 24. The secondary support sliding sleeve 27 is a cylindrical structure with a rectangular cross-section and extends vertically. The secondary support sliding beam 28 extends vertically, its top end is telescopically inserted into the secondary support 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 support sliding beam 28. The two-stage telescopic scheme can reduce the volume of the traveling device and save the occupied space.

[0061] Furthermore, a slewing locking cylinder 29 is used to connect between the longitudinal beam device 1 and the running device 2. When the support device 3 props up the work vehicle to make it unloaded, the slewing locking cylinder 29 is used to limit the relative rotation between the longitudinal beam device 1 and the running device 2, so that the two remain relatively fixed, thereby preventing the longitudinal beam device and the running device 2 from rotating at will when unloaded.

[0062] The running device 2 can be extended and retracted in the horizontal and vertical directions relative to the longitudinal beam device 1 , and can be rotated relative to the longitudinal beam device 1 .

[0063] This embodiment also provides a method for implementing the rail lifting device 4: Figure 6 As shown, 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 or the telescopic beam 12 through a lifting cylinder 43. The lifting 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 there can be two of them, which are used to lift the turnout from both sides in the transverse direction.

[0064] This embodiment provides a specific implementation method: the main beam 41 is an I-beam, including a top plate and a bottom plate extending in the horizontal direction and a web plate vertically connected between the middle of the top plate and the bottom plate. The top of the rail lifting hook 42 can slide along the two sides of the bottom plate.

[0065] Figure 7 This is a schematic diagram of the structure of the extension beam and the main beam of the rail lifting device in the railway turnout laying and changing operation vehicle provided in the embodiment of the present application. Figure 6 and Figure 7 As shown, further, the rail lifting device 4 also includes: an extension beam 44, which 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 hinged parts, which are connected between the main beam 41 and the extension beam 44 in an articulated manner. When the length of the main beam 41 meets the requirements of the turnout, 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 requirements of the turnout, the extension beam 44 is lowered and docked at the end of the main beam 41 (such as Figure 7 As shown in FIG. 4 , the rail lifting hook 42 can slide on the main beam 41 and the extension beam 44, thereby increasing the distance between the two rail lifting hooks 42. The number of the extension beams 44 can be two, which are symmetrically arranged on the main beam 41.

[0066] The extension beam 44 can also be made of I-beam, so that the rail lifting hook 42 can slide back and forth on the main beam 41 and the extension beam 44. The extension beam 44 includes: a top plate and a bottom plate extending in the horizontal direction, and a web plate vertically connected between the middle of the top plate and the bottom plate; the bottom plate of the extension beam is connected to the bottom plate of the main beam, and the top of the rail lifting hook slides along the two sides of the bottom plate of the extension beam.

[0067] The working vehicle can be provided with six sets of rail lifting devices 4, which are arranged at intervals along the longitudinal direction and can lift the turnout from multiple positions, effectively preventing the turnout from deforming during hoisting. The rail lifting device 4 can be specifically arranged on the longitudinal beam 11, or on the sub-longitudinal beam 14 or the telescopic beam 12.

[0068] The above-mentioned rail lifting device 4 performs vertical telescopic movement with the longitudinal beam device 1, so as to lift and lower the turnout.

[0069] The function of the above-mentioned support device 3 is to support on the ground and lift the whole working vehicle to a certain height. The present embodiment provides a specific implementation manner of the support device 3: Figure 8 It is a schematic structural diagram of the support device in the railway turnout laying and replacing working vehicle provided by the embodiment of the present application. As Figure 8 shown, the support device 3 includes: a support main body and a support base. Among them, 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 or the sub-longitudinal beam 14. The second transverse sliding sleeve 31 is a cylindrical structure with a rectangular cross-section and extends along the transverse direction.

[0070] The second transverse sliding beam 32 extends along the transverse direction, and one end of it can be 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 end of the support base 34, and the support column can be telescopically inserted into the second pillar sliding sleeve 33. The telescoping of the second transverse sliding beam 32 enables the support device 3 to perform transverse telescoping, and the telescoping of the support base 34 enables up and down movement.

[0071] The telescoping of the support device 3 can be driven hydraulically. The support device 3 can adopt single-stage vertical telescoping or two-stage vertical telescoping, and can be specifically set with reference to the above-mentioned running device. The above-mentioned support device 3 can perform transverse and vertical telescoping movements relative to the longitudinal beam device 1.

[0072] Figure 9 It is a schematic diagram of the railway turnout laying and replacing working vehicle provided by the embodiment of the present application in the transportation state. As Figure 9 shown, the turnout laying and replacing working vehicle is transported to the construction site by the flatbed truck 5. During transportation, the running device 2 and the support device 3 are both lifted and retracted. The working vehicle is fixed to the flatbed truck 5 through the fixing seat 51, and the fixing seat 51 can be a structure arranged on the flatbed truck 5. The fixing seat 51 can be a hydraulic driving mechanism.

[0073] Figure 10 It is a schematic diagram of the railway turnout laying and replacing working vehicle getting off provided by the embodiment of the present application. AsFigure 10 As shown in the figure, when the flatbed truck 5 transporting the working vehicle arrives at the construction site, the fixed seat 51 is opened, the support device 3 is laterally deployed and lowered to the ground. After the working vehicle is lifted to a certain height, the traveling device 2 is laterally deployed and vertically moved to the ground to support the working vehicle. Then the support device 3 is raised and laterally moved back. The flatbed truck 5 leaves the site, completing the unloading operation of the working vehicle.

[0074] Figure 11 This is a schematic diagram of the railway turnout laying and replacement working vehicle provided by the embodiment of the present application for lifting and lowering the turnout on the turnout transport vehicle. As Figure 11 shown, the turnout transport vehicle 6 transports the turnout 7 to the laying site. The working vehicle moves above the turnout transport vehicle 6 through the traveling device 2, specifically straddling above the turnout transport vehicle 6. Then the turnout is lifted by the rail lifting device 4, and the turnout transport vehicle 6 leaves the site. The working vehicle moves 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.

[0075] The working vehicle provided by this embodiment adopts the longitudinal beam device 1, the traveling device 2, the support 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 turnout laying and replacement alignment, aiming to solve the construction pain points of turnout laying and replacement.

[0076] 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 support 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 random rotation between the traveling device 2 and the longitudinal beam 11.

[0077] 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 lateral movement of the crawler traveling mechanism 26 can avoid obstacles and bypass obstacles on the ground.

[0078] 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. When one power system fails, the other power system can independently drive the whole machine to operate.
