[0003] Traditional ballast cleaning excavators often have problems of inconvenient movement and low transfer efficiency in design and use. Especially when it is necessary to frequently change the operation location or move over a long distance, the moving method of traditional ballast cleaning excavators is often time-consuming and laborious, and is likely to cause unnecessary damage to the equipment itself and the railway line. Summary of the Invention

[0004] The purpose of the utility model is to provide a fast walking assembly for the problems existing in the prior art.

[0005] To achieve the above purpose, the utility model is realized by adopting the following technical solutions: a fast walking assembly, including a ballast cleaning excavator, with a driven main frame and a driving frame respectively installed at both ends of the ballast cleaning excavator, and hydraulic cylinders connected to the ballast cleaning excavator are respectively arranged on the driven main frame and the driving frame; a pin shaft is installed on the driven main frame, a driven sub-frame is sleeved on the pin shaft, a pair of motors are respectively installed on the driven sub-frame and the driving frame, transmission shafts are respectively installed at the output ends of the two pairs of motors, and railway wheels are respectively installed at the other ends of the transmission shafts.

[0006] By adopting the above technical solutions, this fast walking assembly realizes the stability, flexibility and high efficiency of the ballast cleaning excavator during the walking process through a clever structural design and advanced power configuration, providing strong support for fields such as railway maintenance and construction.

[0007] Optionally, a driven baffle is installed at one end of the driven main frame far away from the ballast cleaning excavator, the number of the driven baffles is multiple, and the driven baffle in the middle is larger than the driven baffles on both sides.

[0008] By adopting the above technical solutions, this design effectively enhances the protection ability at the front end of the assembly, prevents external objects (such as gravel, sundries, etc.) from directly hitting the driven main frame and internal key components, thereby protecting the overall structure of the assembly, reducing the maintenance cost and downtime. At the same time, the larger middle baffle can more effectively disperse the impact force, further improving the protection effect.

[0009] Optionally, mounting seats are respectively installed on the side walls on both sides of the driven main frame. A backing plate is provided on the mounting seat, and an oil groove and an oil hole are formed on the surface of the backing plate.

[0010] By adopting the above technical solution, this design reduces the friction and wear of the driven sub-frame within the driven main frame through the backing plate, prolongs the service life of the components. The arrangement of the oil groove and the oil hole ensures the continuous supply of lubricating oil, reduces the friction coefficient, improves the flexibility and smoothness of the movement of the driven sub-frame, and thus enhances the efficiency and reliability of the entire traveling system.

[0011] Optionally, an active baffle is installed at one end of the active frame away from the screening excavator, and a protective cover and a wheel seat are installed inside the active frame.

[0012] By adopting the above technical solution, the setting of the active baffle further enhances the protection ability at the rear end of the component, and together with the driven baffle, constitutes a comprehensive protection system. The addition of the protective cover improves the structural stability and safety of the equipment, provides additional protection for key components such as the wheel seat, prevents damage caused by vibration, impact or external environmental factors, and enhances the overall durability and reliability of the system.

[0013] Optionally, the number of the hydraulic cylinders is two pairs, and both ends of the two pairs of hydraulic cylinders are respectively connected to the screening excavator, the driven main frame and the active frame through connecting shafts.

[0014] By adopting the above technical solution, this layout design ensures the stable support and precise adjustment ability of the traveling system. By controlling the telescopic amount of the hydraulic cylinders, the precise adjustment of the lifting height of the driven main frame and the active frame can be realized, so as to adapt to different working environments and track conditions.

[0015] Optionally, the pin shaft is located at the middle position of the driven main frame, the pin shaft penetrates and extends to the outside of the driven main frame, and both ends of the pin shaft are respectively connected to the driven main frame through fixing parts.

[0016] By adopting the above technical solution, this design ensures the precise positioning and stable connection of the pin shaft, provides a stable rotation axis for the driven sub-frame. At the same time, this design fully considers the possible height difference in the left-right direction of the railway track in actual application, enables the screening excavator to automatically adjust its posture during driving, ensures good contact between the rail wheels and the track, and improves the adaptability and stability of the equipment.

[0017] Optionally, a metal sleeve is provided between the pin shaft and the driven sub-frame, and gaskets are provided at both ends of the metal sleeve.

[0018] By adopting the above technical solution, a metal sleeve and a gasket are provided between the pin shaft and the driven sub-frame. The metal sleeve and the gasket have excellent lubrication and wear resistance properties, effectively reducing the friction and wear between the pin shaft and the driven sub-frame, and extending the service life of the components. In addition, this design also improves the stability and reliability of the driven sub-frame, ensuring the smooth operation of the traveling system.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] 1. By providing hydraulic cylinders on the driven main frame and the active frame, the fast-traveling component of the present utility model can flexibly switch the traveling state according to different working environments and requirements. The combination of the motor, the transmission shaft, and the rail wheels constitutes an efficient traveling drive system. The motor provides power, which is transmitted to the rail wheels through the transmission shaft, enabling the ballast cleaning excavator to move smoothly and quickly along the rails. At the same time, due to the design of the rail wheels fully considering the matching with the rails, the friction and resistance during the movement are reduced, further improving the movement efficiency. 2. The driven sub-frame in the fast-traveling component is connected to the driven main frame through a pin shaft and can swing up and down within a certain range. This design fully considers the possible height difference in the left-right direction of the railway track in actual applications, enabling the ballast cleaning excavator to automatically adjust its posture during driving, ensuring good contact between the rail wheels and the track, and improving the adaptability and stability of the equipment. 3. The settings of the driven baffle and the active baffle, as well as the protective cover and the wheel seat inside the active frame, not only enhance the overall structural strength of the equipment but also improve the safety performance during movement. These protective measures can effectively prevent accidental collisions and damages, ensuring the safety of construction personnel. BRIEF DESCRIPTION OF THE DRAWINGS

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0031] As Figure 1 As shown in -7, the specific solution of the embodiment is as follows: A fast walking assembly includes a ballast cleaning excavator 1. The ballast cleaning excavator 1 is used as the core equipment. The ballast cleaning excavator 1 is mainly responsible for cleaning debris such as ballast and gravel under the track, ensuring the stability of the railway line and the safe operation of the train. Through efficient cleaning operations, the maintenance quality of the railway line is improved, the service life is extended, and the safe operation of the train is guaranteed at the same time.

[0032] The two ends of the ballast cleaning excavator 1 are respectively installed with a driven main frame 2 and a driving frame 3. The driven main frame 2 and the driving frame 3 are used as supporting and connecting structures. They not only carry key components such as a hydraulic cylinder 4, a motor 7, a transmission shaft 8, and a rail wheel 9, but also achieve the overall stability and flexibility of the walking system through reasonable design. At the same time, the walking state can be flexibly adjusted according to different working environments;

[0033] One end of the driven main frame 2 away from the ballast cleaning excavator 1 is provided with a driven baffle 201. The number of the driven baffles 201 is three, and the driven baffle 201 in the middle is larger than the driven baffles 201 on both sides. Mounting seats 202 are respectively installed on the side walls on both sides of the driven main frame 2. A backing plate 203 is provided on the mounting seat 202. The mounting seat 202 is installed on the side walls on both sides of the driven main frame 2 to support the backing plate 203. An oil groove 204 and an oil hole 205 are formed on the surface of the backing plate 203. The design of the backing plate 203 reduces the friction and wear of the driven sub-frame 6 in the driven main frame 2. The arrangement of the oil groove 204 and the oil hole 205 ensures the continuous supply of lubricating oil, further reduces the friction coefficient, and improves the movement flexibility and service life of the driven sub-frame 6. One end of the active frame 3 away from the ballast cleaning excavator 1 is provided with an active baffle 301. The arrangements of the driven baffle 201 and the active baffle 301 effectively prevent the impact and damage of external objects on the components, and at the same time enhance the overall rigidity and anti-deformation ability of the components. A protective cover 302 and a wheel seat 303 are installed inside the active frame 3. The protective cover 302 is installed inside the active frame 3, further enhancing the structural stability and safety of the equipment, providing a stable support for the wheel seat 303, preventing loosening or damage caused by vibration or impact, and improving the overall reliability and durability of the system.

[0034] Hydraulic cylinders 4 connected to the ballast cleaning excavator 1 are respectively provided on the driven main frame 2 and the active frame 3. The hydraulic cylinders 4 are hydraulically driven to realize the lifting adjustment of the driven main frame 2 and the active frame 3. By controlling the telescopic amount of the hydraulic cylinders 4, the precise adjustment of the lifting height of the driven main frame 2 and the active frame 3 can be realized. The number of the hydraulic cylinders 4 is two pairs, and both ends of the two pairs of hydraulic cylinders 4 are respectively connected to the ballast cleaning excavator 1, the driven main frame 2 and the active frame 3 through connecting shafts 401;

[0035] A pin shaft 5 is installed on the driven main frame 2. The pin shaft 5 serves as the rotation axis of the driven sub-frame 6 and is connected to the driven main frame 2 through a fixing member 501; a metal sleeve 502 and a gasket 503 are respectively arranged between the pin shaft 5 and the driven sub-frame 6 to reduce friction and wear. The pin shaft 5 is located at the middle position of the driven main frame 2. The pin shaft 5 penetrates and extends to the outside of the driven main frame 2. Both ends of the pin shaft 5 are respectively connected to the driven main frame 2 through fixing members 501. A metal sleeve 502 is arranged between the pin shaft 5 and the driven sub-frame 6. Gaskets 503 are arranged at both ends of the metal sleeve 502. The metal sleeve 502 and the gasket 503 have excellent lubrication and wear resistance, effectively extending the service life of the pin shaft 5 and the driven sub-frame 6; at the same time, the precise positioning and stable connection of the pin shaft 5 also ensure the stability and reliability of the driven sub-frame 6. The driven sub-frame 6 is sleeved on the pin shaft 5, and the size of the driven sub-frame 6 is smaller than that of the driven main frame 2.

[0036] A pair of motors 7 are respectively installed on the driven sub-frame 6 and the active frame 3. The motors 7 serve as power sources and drive the rail wheels 9 to rotate through transmission shafts 8, thereby enabling the fast-walking assembly to move on the rails. The efficient and stable output of the motors 7 provides sufficient driving force for the fast-walking assembly; the output ends of the two pairs of motors 7 are respectively installed with transmission shafts 8, and the precise transmission of the transmission shafts 8 ensures the smooth rotation of the rail wheels 9; the other ends of the transmission shafts 8 are respectively installed with rail wheels 9, and the good matching between the rail wheels 9 and the rails ensures the stability and safety of the movement. At the same time, this combined design also enables the fast-walking assembly to cope with rail environments with different gradients, curvatures and speed requirements.

[0037] The working steps of the above embodiment on the rails are as follows:

[0038] The working steps on the rails: Place the screening and digging machine 1 on the rails and adjust the position of the screening and digging machine 1 so that its rail wheels 9 are accurately aligned with the rails. By starting the hydraulic cylinder 4, the driven main frame 2 and the active frame 3 are lowered, synchronously driving the rail wheels 9 so that the rail wheels 9 are accurately placed on the rails. Continue to start the hydraulic cylinder 4 to support the screening and digging machine 1 so that the crawlers of the screening and digging machine 1 are suspended. When the screening and digging machine 1 is working on the ground, its moving main frame and the active frame 3 are raised by the hydraulic cylinder 4;

[0039] Start the motor 7, drive the rail wheel 9 to rotate through the transmission shaft 8, and make the fast-walking assembly start to move on the rails;

[0040] When the fast-walking assembly travels to the section that needs to be cleaned, start the screening and digging machine 1 to clean the ballast, gravel and other sundries under the track.
