[0029] Track support frame 10;

[0030] At least one pair of rail clamping assemblies 20, each pair of rail clamping assemblies includes two rail clamping assemblies, the two rail clamping assemblies are symmetrically arranged on both sides of the track support frame 10, and the two rail clamping assemblies are respectively used to clamp the two rails in the working area;

[0032] A longitudinal moving assembly 40, the moving end of which is connected to the track support frame 10;

[0033] The transverse moving assembly 50 has a moving end connected to the track lifting support frame 10 .

[0034] In the present application, a rail clamping assembly is used to clamp the rails in the working area, and then the track is lifted through the track lifting drive assembly. During the track lifting process, the track lifting support frame is longitudinally adjusted through the moving end of the longitudinal movement assembly, thereby longitudinally adjusting the entire track lifting device, so that when an obstacle is encountered during the operation, the rail clamping assembly is longitudinally moved to avoid the obstacle, which can not only meet the track lifting operations of straight or curved tracks, but also adapt to the track lifting operations of complex track lines in the turnout area; the track lifting support frame is transversely adjusted through the moving end of the transverse movement assembly, thereby transversely adjusting the entire track lifting device, so that the transverse position of the rail clamping assembly can be adjusted at any time during the operation, and then the rail clamping assembly is adapted to the position of the rail that needs to be lifted, which can meet the use requirements of straight or curved tracks. The coordinated use of the longitudinal movement assembly and the transverse movement assembly improves the adaptability and maneuverability of the track lifting device provided by the present application, reduces the impact of obstacles during the track lifting process, and greatly improves the operation quality and efficiency.

[0035] The track-lifting device provided in the present application may include a pair of rail clamping assemblies, or may include multiple pairs of rail clamping assemblies, which are longitudinally arranged between the multiple pairs of rail clamping assemblies, and the multiple pairs of rail clamping assemblies have the same working principle, and can better clamp the rails. For the purpose of brevity and saving space, a pair of rail clamping assemblies will be used as an example for explanation below. Furthermore, each rail clamping assembly may include a rail clamping component to clamp or release one side of the track, or may include two rail clamping components to clamp or release both sides of the track at the same time. Figure 2 A front view of a track lifting device for track operation provided in an embodiment of the present application, such as Figure 2 As shown, Figure 2 The utility model comprises two rail clamping parts.

[0036] Further, the rail clamping assembly 20 comprises:

[0037] A rail clamping housing 201, wherein the bottom of the rail clamping housing 201 is provided with an opening;

[0038] The rail clamping component includes a tilting cylinder 202 and a rail clamp 203. The fixed end of the tilting cylinder 202 is connected to the inner wall of the rail clamp housing 201, and the rail clamp 203 is connected to the movable end of the tilting cylinder 202. After the tilting cylinder 202 drives the rail clamp 203 to tilt through the bottom opening of the rail clamp housing 201, the rail clamp clamp clamps one side of the rail in the working area.

[0039] Specifically, the top of the rail clamping housing may also be provided with an opening, and the fixed end of the tilting cylinder 202 is connected to the top opening of the rail clamping housing.

[0040] In the present application, the rail clamp housing supports the turning cylinder and protects the side of the rail clamp to prevent the rail clamp from being damaged by external obstacles; the rail clamp can be controlled by the turning cylinder. When the rail clamp is not clamped, it retracts into the rail clamp housing to avoid interference with the rail row and damage.

[0041] Furthermore, there are two rail clamping parts, which are arranged adjacent to each other in the longitudinal direction and in opposite directions; after the turning cylinders 202 on the two rail clamping parts drive the corresponding rail clamps 203 to turn through the bottom opening of the rail clamping housing 201, the two rail clamps respectively clamp the two sides of the rails in the working area towards each other or release them away from each other. During use, one of the turning cylinders can be used alone to drive the corresponding rail clamp to clamp the rails, or the two turning cylinders can be used together.

[0043] Furthermore, the track-lifting device further includes a locking assembly 60; the locking assembly 60 includes:

[0044] The locking seat 601 is arranged on the top of the track support frame 10, and a locking hole is arranged on the top of the locking seat 601;

[0045] The locking bracket 602 is spaced and arranged just above the locking seat 601;

[0046] The locking moving block 603 is disposed between the locking seat 601 and the locking bracket 602. The top end of the locking moving block 603 is rotatably connected to the locking bracket 602. The bottom end of the locking moving block 603 is provided with a locking hook.

[0047] A locking drive component 604, one end of which is hinged to the locking bracket 602, and the other end of which is hinged to the locking moving block 603. The locking drive component 604 drives the locking moving block 603 and the locking hook to rotate, and when the locking hook rotates to the locking position, it is locked with the locking hole on the locking seat 601, and when the locking hook rotates to the unlocking position, it is unlocked with the locking hole on the locking seat 601.

[0048] In the present application, a locking assembly is provided so that the entire track-lifting device can be locked by locking the track-lifting support frame in a non-operating state, so that the track-lifting drive assembly is not subjected to the downward force of the support frame in a non-operating state, which can protect the track-lifting drive assembly, increase the service life of the track-lifting drive assembly, and make it safer and more stable. In the present application, the locking driving component can drive the locking moving block to move toward or away from the locking seat, thereby achieving locking and unlocking, and the structure is simple and easy to operate.

[0049] Figure 4 A top view of a track lifting device for track operation provided in an embodiment of the present application, such as Figure 4 As shown, further, the longitudinal movement assembly 40 includes a longitudinal movement fixing frame 401 and a longitudinal movement driving component 402, the moving end of the longitudinal movement driving component 402 is hinged to the track support frame 10, and the fixed end of the longitudinal movement driving component 402 is hinged to the longitudinal movement fixing frame 401.

[0050] Furthermore, the transverse movement assembly 50 includes a transverse movement fixing block 501 and a transverse movement driving component 502 , the movable end of the transverse movement driving component 502 is hinged to the track support frame 10 , and the fixed end of the transverse movement driving component 502 is hinged to the transverse movement fixing block 501 .

[0051] In the present application, the track lifting support frame is driven to move longitudinally by a longitudinal driving component, thereby driving the rail clamping assembly to move longitudinally to avoid obstacles; the track lifting support frame is driven to move laterally by a transverse driving component, thereby driving the rail clamping assembly to move laterally to adapt to the position of the rail. The track lifting support frame can be conveniently adjusted in the longitudinal and transverse directions, and the operation is simple and easy to use.

[0052] Furthermore, a support guide column 80 is also provided on the top of the track lifting support frame 10, and the track lifting drive assembly 30 and the support guide column 80 are respectively arranged on the front end top and the rear end top of the track lifting support frame 10; the support guide column 80 and the track lifting drive assembly 30 jointly provide an upward supporting force for the track lifting support frame 10; the rail clamping assembly is arranged on one end of the track lifting support frame 10 close to the track lifting drive assembly 30.

[0053] In the present application, the structure of the track-lifting device is made more stable by setting the support guide column. In the operating state, the support guide column and the track-lifting driving assembly respectively provide an upward force to the front and rear ends of the track-lifting support frame, so that the track-lifting support frame remains balanced. In the non-operating state, the support guide column and the locking assembly provide an upward force to the track-lifting support frame. This is suitable for use in an environment where the track-lifting support frame is relatively long.

[0054] Specifically, there are two track-lifting drive assemblies, and the two track-lifting drive assemblies can be respectively connected to the top of the track-lifting support frame just above the two rails. When the rail clamping assembly clamps the two rails respectively, the rails can be conveniently lifted by the two track-lifting drive assemblies just above the two rails, which is more labor-saving, avoids damage to the track-lifting support frame, and has a better track-lifting effect.

[0055] Furthermore, the track lifting device further includes two roller assemblies 70, which are respectively used to run on two rails in the working area; each roller assembly 70 includes:

[0056] A roller housing 701, the roller housing 701 is connected to the front end of the rail clamp housing 201, and an opening is provided at the bottom of the roller housing 701;

[0057] The guide wheel 702 is rotatably connected to the inside of the roller housing 701 via a rotating shaft. The guide wheel 702 contacts the corresponding rail through the bottom opening of the roller housing 701.

[0058] In the present application, the roller assembly is used to make the track lifting device more compatible with the rail. Through the coordinated use of the support guide column and the roller assembly, the longitudinal movement assembly can accurately grasp the direction during use, making it easier to avoid obstacles and other positions that cannot be clamped, thereby achieving a better use effect.

[0059] The embodiment of the present application also provides a working vehicle for track operation, including a working vehicle body and a track-lifting device for track operation as described above, which is arranged on the working vehicle body; one end of the track-lifting driving assembly 30 away from the track-lifting support frame 10, one end of the support guide column 80 away from the track-lifting support frame 10, the top of the locking bracket 602, one end of the longitudinal moving assembly 40 away from the track-lifting support frame 10, and one end of the transverse moving assembly 50 away from the track-lifting support frame 10 are all connected to the working vehicle body. Specifically, the working vehicle can be a cleaning vehicle.

[0060] Since the work vehicle provided by the present application includes the above-mentioned track-lifting device, it can be considered to have the same beneficial effects as the above-mentioned track-lifting device, and no further description is given here. In addition, the top of the track-lifting drive assembly, the top of the support guide column, the top of the locking bracket, the end of the longitudinal movement assembly away from the track-lifting support frame, and the end of the transverse movement assembly away from the track-lifting support frame are all connected to the work vehicle body, making the overall connection structure more stable and capable of realizing track-lifting operations in complex environments of the turnout area.

[0061] Furthermore, an operating device is also provided on the operating vehicle body, and the track-lifting device is located at the front end or the rear end of the operating device; the operating device is one of an excavating device and a tamping device.

[0062] In the present application, the track-lifting device is adjacently arranged at the front end or the rear end of the working device, and is used in conjunction with the working vehicle so that the working vehicle can smoothly perform operations such as excavation and tamping.

[0063] Specifically, the locking drive component 604, the longitudinal drive component 402, the transverse drive component 502, and the track lifting drive assembly are all cylinders.

[0064] More specifically, a hydraulic device is also provided on the work vehicle body to provide hydraulic power for the entire work vehicle.

[0067] Unlocking: The locking driving component 604 drives the locking moving block 603 to rotate to the unlocking position, that is, the locking hook of the locking moving block 603 is unlocked from the locking hole of the locking seat 601; in the unlocking state, the guide wheel 702 contacts the corresponding rail;

[0068] Clamping the rails: Select the rail clamping component to be used, and then drive the corresponding turning cylinder 202 to make the corresponding rail clamp 203 extend downward to clamp the rails in the working area; during the process of clamping the rails, when there are obstacles on the rails, the direction is controlled by the guide wheel 702 and the support guide column 80, and the longitudinal driving component 402 is driven to drive the track lifting support frame 10 to drive the rail clamping assembly 20 to move longitudinally to avoid the obstacles; when there is a distance deviation between the rail clamping component and the corresponding rail in the lateral direction, the track lifting support frame 10 can be driven by the transverse driving component 502 to drive the rail clamping component to make lateral adjustments, so that the rail clamping component can smoothly clamp the corresponding rails;

[0069] Track lifting: The track lifting drive assembly 30 is driven to provide an upward track lifting force to the front end of the track lifting support frame 10, so that the clamping component and the rail clamped by the clamping component can perform the track lifting operation.

[0070] After the track lifting operation is completed, the locking driving component 604 drives the locking moving block 603 to rotate to the locking position, that is, the locking hook portion of the locking moving block 603 is locked with the locking hole of the locking seat 601.
