[0015] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] like Figures 1-3 As shown, a dual-purpose road-rail tamping machine includes a main frame 1, which has an arched structure. An arched gantry in the middle of the main frame 1 carries a working unit. A power system 9 and a driver's cab 8 are mounted on both sides of the main frame 1. Multiple tires 2 are located below the main frame 1. Main mounting seats 10 are located at the front and rear ends of the main frame 1. Guide wheel modules are connected below the main mounting seats 10. The guide wheel modules have liftable rail guide wheels 3. When traveling on the road, the rail guide wheels 3 are retracted and higher than the lowest point of the tires 2. When the rail guide wheels 3 are switched onto the rails, the tires 2 are lifted off the ground. Rotatable auxiliary arms 7 are also located at the front and rear ends of the main frame 1.

[0018] This dual-purpose road-rail tamping machine, through improvements to its travel module, can quickly switch between road travel mode, railway travel mode, and railway operation mode to reach the work site, and it is flexible in entering and exiting the track. The built-in work unit can realize automated tamping operation, which not only retains the operation quality and efficiency of large tamping machines, but also solves the difficulty of small and medium-sized tamping equipment not being able to automatically detect track lifting.

[0019] Compared to other small and medium-sized tamping equipment, this dual-purpose road and rail tamping machine has higher operating efficiency and quality, and can significantly reduce the number of construction workers during operation; compared to large tamping machines, it can be used for both road and rail, making the construction method more flexible, with greater scalability, and significantly reducing equipment production and maintenance costs.

[0020] The auxiliary arms 7 set at the front and rear of the main frame 1 can not only be used in conjunction with the excavator bucket for excavation, but also serve as support arms to transfer the entire road surface in the tamping vehicle to the track. When going up and down the track, the support and deflection of the front and rear auxiliary arms 7 ensure the good passability and climbing ability of the whole vehicle.

[0021] Furthermore, in combination Figure 4 As shown, the guide wheel module includes a drive-end guide wheel assembly disposed at one end of the main frame 1. The drive-end guide wheel assembly includes a first connecting frame 13, which is connected to the mounting position of the main mounting seat 10 via a hinge shaft. A pair of first support cylinders 14 are provided on the first connecting frame 13, and the upper end of the first support cylinders 14 is connected to the main mounting seat 10 via a cylinder pin. A pair of rail guide wheels 3 are provided at both ends of the first connecting frame 13. A drive motor 15 that connects to and drives the rail guide wheels is also provided on the first connecting frame 13.

[0022] By extending and retracting the first support cylinder 14, the first connecting frame 13 (with guide wheels) rotates around the fixed hinge axis, thus completing the switching of the module's retraction and extension states.

[0023] Furthermore, in combination Figure 5 As shown, the guide wheel module includes a floating end guide wheel assembly disposed at one end of the main frame. The floating end guide wheel assembly includes a second connecting frame 16. The second connecting frame 16 is connected to the corresponding mounting position of the main mounting seat 10 via a hinge shaft. A pair of second support cylinders 17 connected to the main mounting seat are mounted on the second connecting frame 16. The second connecting frame 16 is connected to a floating frame 19 via a floating hinge shaft 18. The rail guide wheels 3 are respectively provided at both ends of the floating frame 19. A locking cylinder 20 is provided on the inner side of the floating frame 19, which is connected to and cooperates with the second connecting frame 16.

[0024] Unlike the drive end, the second connecting frame of the floating end has a hinge point, with the floating hinge shaft connecting to the floating frame. The floating frame can swing around the hinge point at a certain angle. Locking cylinders are located on both sides inside the second connecting frame, connected by bolts. When necessary, the piston rod can extend and contact and hold with the locking cylinder support block on the floating frame, thus locking the floating function. A disc brake is located near the inner side of the guide wheel on the rail, used for braking and adjusting the overall vehicle speed.

[0025] The nearly vertically arranged support cylinders offer structural stability, good stress distribution, and a longer service life. The application of the mature disc brake 21 is cheaper and easier to maintain compared to a hydraulic motor-integrated brake solution. The locking cylinder 20 can lock the floating function at any time, adjusting the vehicle's stability and the rigidity of the guide wheel structure.

[0026] Furthermore, the main mounting base 10 has a connecting lug 22 on its side, which is connected to the auxiliary arm hinge seat 23 at the end of the auxiliary arm 7. The end of the main frame 1 has an auxiliary arm control cylinder 24, which is connected to the auxiliary arm hinge seat 23. The main mounting base 10 has a clearance hole for the auxiliary arm control cylinder 24 to pass through. The auxiliary arm control cylinder 24 can control the direction of the swing of the auxiliary arm 7, allowing for flexible control of the auxiliary arm 7.

[0027] Furthermore, the main frame 1 includes a central bow-shaped mast 101 and support frames 102 disposed on both sides of the bow-shaped mast 101. The working unit is installed inside the bow-shaped mast 101. The power system 9 is mounted on one side of the support frame 102, and the cab 8 is disposed on the other side of the support frame 102. The main mounting seat 10 is disposed at the end of the support frame 102. A plurality of vertical connecting rods 11 are also provided above the main mounting seat 10. A top frame 12 is also provided above the main frame 1. The top frame 12 is connected to the plurality of vertical connecting rods 11 at the front and rear ends respectively.

[0028] The main frame 1, through the setting of the bow-shaped gantry and the two side support frames, can obtain an upward-concave installation space in the middle, which can be used to arrange the working units that need to move. At the same time, the space on both sides is used to arrange the cab and hydraulic and power systems, which not only makes reasonable use of the space on both sides, but also balances the weight of the whole vehicle.

[0029] The cab 8 is equipped with a driver's seat that can rotate 180 degrees. When the tamping machine is in motion, the driver faces directly forward along the route. When tamping operations are being performed, the driver's seat can rotate 180 degrees to allow the driver to see behind, specifically the tamping module. The tamping module is located on the side furthest from the cab, which further expands the driver's field of vision, ensuring that the driver can better and more comprehensively observe the operation of the tamping module during operation.

[0030] Furthermore, in combination Figure 6 As shown, the working unit includes a measurement module 5, which includes a measurement trolley frame 501. A retractable connecting sleeve 502 is provided above the measurement trolley frame 501, and the connecting sleeve 502 is connected to the main frame 1. A pair of measurement wheels 503 that self-adhere to the track are provided below the trolley frame 501, and a displacement sensor 504 is provided below the trolley frame 501.

[0031] The pair of measuring wheels 503 are positioned on a pair of rails during use. The measuring wheels 503 allow the trolley frame 501 to straddle the rails, moving in real-time along with the main frame 1. During this movement, multiple displacement sensors 504 located beneath the trolley frame monitor the lateral and longitudinal distances of the rails, providing their lateral and longitudinal positions. When the main frame stops at the working position, the measuring wheels 503 remain stationary on the rails. During operation, the displacement sensors 504 monitor the lateral and longitudinal distances of the rails, providing their lateral and longitudinal positions. Because the rail positions change during construction, measuring these positions sequentially facilitates subsequent rail restoration.

[0032] Furthermore, the working unit also includes a track-setting module 4, combined with... Figure 7-10 As shown, the track-setting module 4 includes a track-setting frame 401, on which a pair of track-setting cylinders 402 and a pair of track-setting cylinders 403 are provided. A pair of track-setting clamps and a pair of track-setting wheels 408 are installed at the lower end of the track-setting frame 401. The pair of track-setting cylinders 403 are arranged in a cross configuration. The upper end of each track-setting cylinder 403 is connected to the main frame 1 via a track-setting mounting seat, and the lower end is hinged to the track-setting frame 401. The upper end of the lifting cylinder component 402 is connected to the main frame 1 via a lifting mounting seat, and the lower end is hinged to the lifting track frame 401. The lifting track frame 401 is also provided with a traction seat 404, which is connected to the lifting track frame 401 via a transverse connecting member. The traction seat 404 is provided with a lifting guide shaft 409, and a fixed seat 410 is installed on the lifting guide shaft 409. The fixed seat 410 is connected to the main frame 1.

[0033] Through the coordinated design of components such as the traction seat 404, the lateral connecting member, the lifting guide shaft 409, and the fixed seat, the track lifting mechanism can be adjusted in multiple directions with multiple degrees of freedom. The lateral connecting member allows the track lifting frame to move laterally and swing at a certain angle relative to the traction seat. The cooperation between the lifting guide shaft and the fixed seat realizes the lifting adjustment of the mechanism. This multi-degree-of-freedom design enables the mechanism to flexibly adapt to changes in the track line in the lateral, longitudinal, and height directions, meet the operational needs under different working conditions, and enhance the adaptability and flexibility of the equipment.

[0034] The rail clamping device includes two clamping seats 405 connected to the rail lifting frame 401. A clamping cylinder 407 is provided between the two clamping seats 405, and adjustable rail clamping wheels 406 are respectively installed below the two clamping seats 405. With the cooperation of the clamping cylinder 407, the rail clamping wheels 406 are opened and closed to clamp and release the rail. This connection method allows the clamping seats to move flexibly to adapt to rails of different specifications and shapes, improving the stability and reliability of rail clamping.

[0035] Furthermore, the lateral movement connector includes a lateral movement guide shaft 411 mounted on the traction seat 404. A lateral movement sleeve 412 is fitted around the outer periphery of the lateral movement guide shaft 411, and a lateral movement seat 413 is mounted around the outer periphery of the lateral movement sleeve 412. A first swing shaft 414 connected to the track-setting frame 401 is mounted on the lateral movement seat 413, and a buffer pad 415 is also mounted around the outer periphery of the first swing shaft 414. The lateral movement connector enables the track-setting frame 401 to move laterally and swing at a certain angle relative to the traction seat 404, increasing the degree of freedom of the track-setting mechanism in the lateral direction. This design allows the track-setting mechanism to better adapt to lateral changes in the track line, such as track bending and offset. The buffer pad reduces the impact force on the swing shaft during movement, protecting the components from damage and improving the service life and operational stability of the lateral movement connector.

[0036] Furthermore, the work unit also includes a tamping module 6, combined with... Figure 11 and Figure 12 As shown, the tamping module 6 includes a tamping transverse shaft 601 connected to the main frame 1. A movable guide frame 602 is provided below the tamping transverse shaft 601. A movable lifting seat 603 is provided inside the guide frame 602. Rotary shaft seats 604 connected to the lifting seat 603 are provided on both sides of the guide frame 602. The lower part of the rotary shaft seat 604 is connected to a swing seat 605 through a rotary shaft seat pivot 608. The two ends of the swing seat 605 are respectively connected to a deflectable tamping pick seat 606. Multiple detachable tamping picks 607 are provided below the tamping pick seat 606. A flywheel energy storage assembly is also provided on the rotary shaft seat 604. The flywheel energy storage assembly is connected to the swing seat trunnion plate 610 on the swing seat 605 through a telescopic clamp 617.

[0037] The guide frame 602 is located below the transverse axis 601 and can move relative to the transverse axis 601, thereby adjusting the lateral position of the tamping pick seat 606 and tamping pick 607 connected and installed below it for tamping construction in different areas; the guide frame 602 is provided with multiple lifting guide columns 613, and the lifting seat 603 is connected to the lifting guide columns 613; a vertical lifting telescopic component 612 is also connected to one side of the guide frame 602; the lifting seat 603 is located inside the guide frame 602 and can move up and down relative to the guide frame 602 to drive the rotating shaft seat 604 to move up and down synchronously, thereby adjusting the height position of the tamping pick seat 606 and tamping pick 607 connected and installed below it. The swing seat 605 can rotate relative to the pivot seat 604, and the swing seat will rotate around the pivot at a certain angle to achieve clamping of the tamping pick; the tamping pick seat 606 can deflect relative to the swing seat 605, and will rotate around the swing axis at a certain angle to achieve deflection of the tamping pick.

[0038] Each guide frame 602 has a swing seat 605 on both sides along its length. A connecting plate 609 is provided above the swing seat 605 near the pivot seat, and the connecting plate is connected to the pivot. A pair of ear plates of the tamping pick seat 606 are connected to the swing seat 605 through a second swing shaft 618. A deflection telescopic member 611 is also connected to one side of the tamping pick seat 606. The other end of the deflection telescopic member 611 is connected to the connecting plate 609 or the swing seat trunnion plate 610 above the swing seat 605.

[0039] Furthermore, the flywheel energy storage assembly includes an eccentric shaft 614 rotatably connected to and passing through the lifting seat 603. One end of the eccentric shaft 614 is connected to an energy storage flywheel 615, and the other end of the eccentric shaft 614 is connected to a vibration motor 616. The energy storage flywheel 615 is mounted on one side of one of the rotating shaft seats 604 via a flywheel bracket, and the vibration motor 616 is mounted on one side of the other rotating shaft seat via a motor support.

[0040] One end of the eccentric shaft 614 is connected to the vibratory motor 616, and the other end is connected to the energy storage flywheel 615. The middle part is fixed to the rotating shaft seat 604 by a bearing. When the vibratory motor 616 rotates, it drives the eccentric shaft 614 to rotate, providing tamping excitation force for vibration. The energy storage flywheel 615 rotates synchronously. The fan-shaped energy storage flywheel 615 not only provides energy storage but also generates a certain amount of wind force, which can cool the bearings on the eccentric shaft, reduce their operating temperature, and prevent the bearings and transmission components from overheating. This not only helps to ensure work efficiency and safety but also effectively improves the service life of the bearings.
