Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of tracked walking mechanisms for support transport vehicles, specifically, to a tracked walking mechanism for support transport vehicles. Background Technology

[0002] In modern industrial production and various engineering operations, the support transport vehicle is a key transportation equipment, and its tracked walking mechanism plays a decisive role in the stable operation under complex terrain.

[0003] Currently, common tracked walking mechanisms suffer from an unreasonable distribution of power sources. Most devices rely on a single or a few centralized hydraulic reducers for power output, resulting in ineffective power distribution. Furthermore, due to the lack of a backup power switching mechanism, if one hydraulic reducer fails, the entire tracked walking mechanism becomes immobile. Taking underground coal mine operations as an example, the tunnel environment is complex, with rugged terrain, numerous obstacles, and varying slopes. Support transport vehicles operate frequently in such conditions, placing high pressure on the hydraulic reducers and increasing their failure rate. A failure not only interrupts the current task and halts the vehicle but may also impede the passage of other vehicles and even disrupt the entire production process.

[0004] From an equipment maintenance perspective, once a malfunction occurs, the power cannot be switched back to continue operation, requiring immediate repairs by maintenance personnel. The complex underground environment makes maintenance extremely difficult, consuming significant manpower, resources, and time. Furthermore, delayed repairs can lead to production stoppages and substantial economic losses.

[0005] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a tracked walking mechanism for a support transport vehicle, which solves the technical problem in the prior art that the lack of a backup power switching mechanism means that the entire tracked walking mechanism cannot move once a hydraulic reducer fails.

[0007] According to one aspect, at least one embodiment of the present disclosure provides a tracked walking mechanism for a support transport vehicle, comprising:

[0008] The system includes a support platform, a pair of side plates, a pair of drive wheels, and a pair of tracks. The side plates are fixed to both sides of the support platform, the drive wheels are rotatably connected between the support platform and the side plates, and the tracks are connected to the drive wheels.

[0009] The inner plate is fixed to the bottom surface of the support platform, and the drive assembly is disposed on the inner plate and the support platform.

[0010] A cleaning assembly, wherein the cleaning assembly is disposed in the support platform;

[0011] The drive assembly includes a stabilizing frame, a pair of sliding rods are provided on the side surface of the stabilizing frame, and the sliding rods are movably fitted inside the side surface of the inner plate. The stabilizing frame is connected to the inner plate by a linear drive. A main shaft is provided in the inner plate, and a main motor is mounted on the stabilizing frame. Both the output end of the main motor and the main shaft are provided with transmission gears.

[0012] As a further technical solution, auxiliary motors are installed on both sides of the support platform. The auxiliary motors are connected to the driving wheels on both sides respectively. Transmission grooves are opened at one end of the rotating shaft of the other driving wheel and at both ends of the main shaft.

[0013] As a further technical solution, a coaxial rod is slidably fitted between the transmission grooves, and a fixing plate is rotatably fitted onto the coaxial rod. Side frames are provided on both sides of the support platform, and a pair of stabilizing rods are provided inside the side frames.

[0014] As a further technical solution, the fixing plate is slidably mounted on a pair of stabilizing rods, the fixing plate is connected to the side surface of the side frame by a linear drive, and the transmission groove and the coaxial rod have a polygonal cross-section.

[0015] As a further technical solution, the cleaning assembly includes a pair of side cavities, which are respectively opened on both sides of the support platform. A rotating shaft is rotatably connected inside the support platform, and both ends of the rotating shaft are located inside the side cavities.

[0016] As a further technical solution, a cleaning brush is provided at both ends of the rotating shaft, a drive motor is provided on the inner plate, and a transmission wheel is provided at the output end of the drive motor and on the rotating shaft. The transmission wheels are connected by belt drive.

[0017] As a further technical solution, both the inner and outer surfaces of the track are toothed structures.

[0018] As a further technical solution, the surface of the support platform is provided with several positioning and mounting holes.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] In this disclosure, the drive assembly solves the problem of lack of backup power in traditional mechanisms through a main and auxiliary motor coordination and power switching mechanism. The auxiliary motor can flexibly steer with independent drive, while the main motor achieves centralized power output through gears and coaxial rods, adapting to complex terrain. The gear meshing and coaxial rod connection of the linear drive control make power switching convenient and reliable, avoiding mechanism stagnation caused by the failure of a single power source. This design improves the reliability of the equipment in harsh environments, reduces production interruptions caused by failures, and the two drive modes adapt to different working conditions, enhancing the passability and practicality of the support transport vehicle.

[0033] like Figures 1-4 As shown, it illustrates a tracked walking mechanism for a support transport vehicle according to an embodiment of the present disclosure, comprising:

[0034] The platform consists of a support platform 1, a pair of side plates 2, a pair of drive wheels 3, and a pair of tracks 4. The side plates 2 are fixed to both sides of the support platform 1, the drive wheels 3 are rotatably connected between the support platform 1 and the side plates 2, and the tracks 4 are connected to the drive wheels 3.

[0035] The inner plate 5 and the drive assembly 6 are provided. The inner plate 5 is fixed to the bottom surface of the support platform 1, and the drive assembly 6 is disposed on the inner plate 5 and the support platform 1.

[0036] Cleaning component 7 is disposed in the support platform 1;

[0037] The drive assembly 6 includes a stabilizing frame 6-1. A pair of sliding rods 6-2 are provided on the side surface of the stabilizing frame 6-1. Both sliding rods 6-2 are movably fitted within the side surface of the inner plate 5. The stabilizing frame 6-1 is linearly driven onto the inner plate 5. A main shaft 6-3 is provided within the inner plate 5. A main motor 6-4 is mounted on the stabilizing frame 6-1. Both the output end of the main motor 6-4 and the main shaft 6-3 are provided with transmission gears 6-5. Auxiliary motors 6-6 are installed on both sides of the support platform 1. The auxiliary motors 6-6 are respectively connected to the driving wheels 3 on both sides. The other driving wheel 3... One end of the rotating shaft 7-2 and both ends of the main shaft 6-3 are provided with transmission grooves 6-7. A coaxial rod 6-8 is slidably fitted between the transmission grooves 6-7. A fixing plate 6-9 is rotatably fitted onto the coaxial rod 6-8. Side frames 6-10 are provided on both sides of the support platform 1. A pair of stabilizing rods 6-11 are provided in the side frames 6-10. The fixing plate 6-9 is slidably fitted onto the pair of stabilizing rods 6-11. The fixing plate 6-9 is connected to the side surface of the side frame 6-10 by linear drive. The cross-section of the transmission groove 6-7 and the coaxial rod 6-8 is a polygonal structure.

[0038] In some examples, to achieve flexible power switching, a drive assembly 6 is designed. This assembly includes a sliding rod 6-2 on the side surface of the inner plate 5 and a movable mounting bracket 6-1. The linear drive pushes the mounting bracket 6-1 to slide along the sliding rod 6-2, adjusting the relative position of the main motor 6-4 and the main shaft 6-3. The output end of the main motor 6-4 can engage or disengage with the transmission gear 6-5 on the main shaft 6-3. Both ends of the main shaft 6-3 are connected to the transmission groove 6-7 of the rotating shaft 7-2 of the drive wheel 3 via polygonal coaxial rods 6-8 to ensure slippage-free power transmission.

[0039] The auxiliary motor 6-6 within the support platform 1 is directly connected to the two drive wheels 3, enabling it to independently drive the tracks 4. The stabilizing rod 6-11 within the side frame 6-10 provides a sliding guide for the fixed plate 6-9. The coaxial rod 6-8 on the fixed plate 6-9 moves along the stabilizing rod 6-11 with the linear drive, allowing the transmission groove 6-7 to be inserted into or separated from the coaxial rod 6-8. Under normal conditions, the coaxial rod 6-8 is separated from the transmission groove 6-7, and the auxiliary motor 6-6 drives the two drive wheels 3 independently, enabling flexible steering. When concentrated power is required, the linear drive pushes the fixed plate 6-9, causing the coaxial rod 6-8 to embed into the transmission groove 6-7 between the main shaft 6-3 and the drive wheel 3. Simultaneously, the main motor 6-4 approaches the main shaft 6-3 via the linear drive, the transmission gear 6-5 meshes, and the power of the main motor 6-4 is transmitted to the drive wheel 3 via the main shaft 6-3 and the coaxial rod 6-8. The auxiliary motor 6-6 then stops working, forming a concentrated drive mode.

[0040] The slide bar 6-2 ensures smooth movement of the stable frame 6-1, while the polygonal transmission groove 6-7 and coaxial rod 6-8 ensure efficient power transmission. The switching between two drive modes adapts to different road conditions, improving the passability of the support transport vehicle in complex terrain.

[0041] like Figures 1-4 As shown in the figure, the cleaning assembly 7 in this embodiment includes a pair of side cavities 7-1, which are respectively opened on both sides of the support platform 1. A rotating shaft 7-2 is rotatably connected inside the support platform 1. Both ends of the rotating shaft 7-2 are located in the side cavities 7-1. A cleaning brush 7-3 is provided at both ends of the rotating shaft 7-2. A drive motor 7-4 is provided on the inner plate 5. A transmission wheel 7-5 is provided at the output end of the drive motor 7-4 and on the rotating shaft 7-2. The transmission wheels 7-5 are connected by a belt drive.

[0042] In some examples, to achieve continuous cleaning of the track 4, a cleaning assembly 7 is designed. This assembly includes side cavities 7-1 on both sides of the support platform 1, providing space for the cleaning structure. An internal rotating shaft 7-2 is rotatably connected via bearings, and cleaning brushes 7-3 at both ends are located within the side cavities 7-1, contacting the inner surface of the track 4. The output end of the drive motor 7-4 on the inner plate 5 is connected to the transmission wheel 7-5 on the rotating shaft 7-2 via a belt, forming a transmission structure.

[0043] During operation, the drive motor 7-4 drives the rotating shaft 7-2 to rotate via the transmission wheel 7-5 and belt. The cleaning brushes 7-3 at both ends rotate synchronously with the rotating shaft 7-2. The brushes are in close contact with the inner side of the track 4, which can sweep off the dirt, gravel and other impurities attached to the track 4, preventing the accumulation of impurities from affecting the transmission of the track 4. The cleaning brushes 7-3 at both ends of the rotating shaft 7-2 are symmetrically distributed to ensure that the track 4 on both sides is cleaned evenly. The belt drive has a buffering effect to prevent the cleaning brushes 7-3 from damaging the motor when they encounter hard objects.

[0044] The enclosed structure of the side cavity 7-1 prevents debris from splashing during cleaning, and the stable transmission relationship between the drive motor 7-4 and the rotating shaft 7-2 ensures that the sweeping brush 7-3 rotates at a uniform speed. This component maintains the contact between the track 4 and the drive wheel 3 through continuous cleaning, reduces wear on the track 4 caused by debris, extends the service life of the walking mechanism, and adapts to the usage needs of environments with many impurities, such as mines and construction sites.

[0045] For example, such as Figure 1 As shown, both the inner and outer surfaces of the track 4 are toothed structures.

[0046] In some examples, the toothed structure on the inner surface of the track 4 meshes with the toothed grooves of the drive wheel 3, while the toothed structure on the outer surface increases the friction with the ground. The toothed structure on the inner surface ensures precise transmission between the track 4 and the drive wheel 3, preventing slippage; the toothed structure on the outer surface can embed itself into the ground in complex terrain, improving grip and preventing slippage during movement, adapting to muddy or rugged environments such as mines and construction sites.

[0047] For example, such as Figure 1 As shown, the surface of the support platform 1 has several positioning and mounting holes 8.

[0048] In some examples, the positioning mounting holes 8 on the surface of the support platform 1 are evenly distributed for securing the transport bracket. The mounting holes mate with the connectors at the bottom of the bracket, and by tightening bolts, the bracket can be firmly fixed to the platform, preventing swaying during transport. The placement of the positioning mounting holes 8 enhances the platform's versatility, allowing it to accommodate brackets of different sizes and ensuring safe transport.

[0049] In actual use: The bracket is fixed on the positioning mounting hole 8 of the support platform 1. The equipment is started. Under normal conditions, the auxiliary motor 6-6 drives the two drive wheels 3 to drive the track 4 to move. Steering is achieved through independent control. At this time, the coaxial rod 6-8 is separated from the transmission groove 6-7, and the transmission gear 6-5 of the main motor 6-4 is not engaged. When encountering complex terrain and needing concentrated power, the linear drive pushes the stabilizing frame 6-1 to move along the slide bar 6-2, so that the transmission gear 6-5 of the main motor 6-4 meshes with the gear of the main shaft 6-3. At the same time, the fixing plate 6-9 slides along the stabilizing rod 6-11, causing the coaxial rod 6-8 to embed into the transmission groove 6-7 between the main shaft 6-3 and the drive wheel 3. The main motor 6-4 drives the track 4 through the main shaft 6-3 and the coaxial rod 6-8, enhancing the power output. During the movement, the drive motor 7-4 drives the rotating shaft 7-2 to rotate through the transmission wheel 7-5 and belt. The cleaning brushes 7-3 at both ends rotate synchronously to clean the impurities attached to the inner surface of the track 4, ensuring that the track 4 and the drive wheel 3 are in close contact. After the operation is completed, the reverse operation is performed to switch to the auxiliary motor 6-6 for drive and the equipment is turned off.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
