Description

Technical Field

[0001] This utility model belongs to the field of track technology, specifically relating to a multi-terrain tracked walking device. Background Technology

[0002] In numerous fields such as engineering operations, agricultural production, military operations, and special rescue, mobile operations are frequently required in various complex and varied terrains. Traditional locomotives, such as ordinary wheeled structures, have significant limitations when facing uneven terrain, mud, sand, rugged mountain roads, and other special terrains. Individual wheels struggle to adapt to large elevation differences, easily leading to vehicle center of gravity shifting, instability, or even getting stuck.

[0003] While tracked locomotives have improved traversability on complex terrain to some extent, most existing tracked locomotives suffer from uneven load distribution. When traveling on uneven ground, the force at the contact points between the tracks and the ground is uneven, with the weight concentrated in a few areas. This not only accelerates localized wear of the tracks and reduces their service life, but also affects the overall maneuverability and stability of the locomotive, increasing energy consumption and operational risks. Utility Model Content

[0004] The purpose of this invention is to provide a multi-terrain tracked walking device that enables multiple load-bearing wheels to push the track body against uneven ground, allowing multiple load-bearing wheels to bear weight, reducing the concentration of gravity, and making the gravity evenly distributed.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A multi-terrain tracked walking device includes a support frame, a drive shaft rotatably connected to the upper side of the support frame, a drive wheel fixedly connected to the outer side of the drive shaft, a bottom support on the lower side of the support frame, a plurality of load-bearing wheels rotatably connected to the lower side of the bottom support, a first guide wheel rotatably connected to one end of the support frame, a tension wheel mechanism installed at the other end of the support frame, and track belts installed on the outer sides of the drive wheel, the first guide wheel, the tension wheel mechanism, and the plurality of load-bearing wheels, with the drive wheel and the track belts being vehicularly connected.

[0007] The bottom support has multiple auxiliary oil chambers inside, and a first sealing plate is vertically slidably connected inside the auxiliary oil chamber. A push rod is fixedly connected to the lower side of the first sealing plate. The lower end of the push rod extends to the lower side of the bottom support, and the load-bearing wheel is rotatably connected to the lower end of the push rod.

[0008] The bottom bracket also has a main oil chamber and multiple oil guide channels inside. The upper ends of the multiple bottom brackets are connected to the lower ends of the main oil chamber through the oil guide channels. The main oil chamber is filled with hydraulic oil, and a pressurizing mechanism for pressurizing the hydraulic oil is installed on the bottom bracket.

[0009] Furthermore, the pressurizing mechanism includes a second hydraulic cylinder fixedly connected to the upper side of the bottom support, and the piston rod of the second hydraulic cylinder extends into the main oil chamber and is fixedly connected to a second sealing plate.

[0010] The technical effects achieved by this utility model are as follows:

[0011] This utility model discloses a multi-terrain tracked walking device that uses hydraulic pressure to push multiple push rods and load-bearing wheels downwards. When the multi-terrain tracked walking device travels on uneven ground, it can make multiple load-bearing wheels push the track body against the ground, thereby enabling multiple load-bearing wheels to bear the weight, reducing the concentration of gravity, and making the gravity evenly distributed.

[0018] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0019] like Figures 1-4 As shown, a multi-terrain tracked walking device includes a support frame 1, on which a suspension bridge 2 can be fixedly connected. The suspension bridge 2 allows the track belt 11 to have better walking performance on special terrains. This design enables the track belt 11 to maintain continuous contact when encountering obstacles or uneven terrain, avoiding slippage or jamming.

[0020] The upper side of the support frame 1 is rotatably connected to the drive shaft 3, and the outer side of the drive shaft 3 is fixedly connected to the drive wheel 4. The drive shaft 3 is used to connect the vehicle's power equipment and drive the drive wheel 4 to rotate. The lower side of the support frame 1 is the bottom bracket 12, and the lower side of the bottom bracket 12 is rotatably connected to multiple load-bearing wheels 7. One end of the support frame 1 is rotatably connected to the first guide wheel 5, and the other end of the support frame 1 is equipped with a tension wheel mechanism. The drive wheel 4, the first guide wheel 5, the tension wheel mechanism and the multiple load-bearing wheels 7 are mounted on the outer side of the track belt body 11, and the drive wheel 4 and the track belt body 11 are connected in a transmission. When the drive wheel 4 rotates, it can drive the track belt body 11 to move on the outer side of the drive wheel 4, the first guide wheel 5, the tension wheel mechanism and the multiple load-bearing wheels 7. A pentagonal structure is formed between the drive wheel 4, the first guide wheel 5, the tension wheel mechanism and the multiple load-bearing wheels 7, which provides stable support and helps to maintain the stable operation of the track belt body 11 on uneven ground.

[0021] The drive wheel 4 is made of steel-aluminum alloy and has light-reducing holes, providing a high-strength and lightweight structural design, which brings advantages in many aspects such as convenient manufacturing, high resistivity, wear resistance, vibration resistance and impact resistance.

[0022] The track body 11 adopts an anchor pattern track, which increases the contact area with the ground, improves traction, reduces ground compaction, and has good stability and passability. At the same time, anti-wear blocks 13 are installed on the track body 11, which can reduce the wear on the track body 11.

[0023] The tensioning wheel mechanism includes a sub-support 10 fixedly connected to the end of the support frame 1. The sub-support 10 has a groove, inside which a drive shaft 9 is slidably connected and can rotate. A second guide wheel 6 is fixedly connected to one side of the drive shaft 9, and a first hydraulic cylinder 8 is also fixedly connected to one side of the sub-support 10. An annular ring is fixedly connected to the piston rod of the first hydraulic cylinder 8, and this annular ring is rotatably connected to the outside of the drive shaft 9. Activating the first hydraulic cylinder 8 moves the second guide wheel 6 and the drive shaft 9. The track belt 11 is mounted on the outside of the second guide wheel 6. The tension of the track belt 11 can be adjusted by moving the second guide wheel 6, making it suitable for different terrains. For example, on snow or sand, the track belt 11 requires tighter tension to increase the contact area with the ground, while on hard ground, looser tension is needed to reduce wear.

[0024] like Figures 1-4 As shown, the installation method of the push rod 16 is disclosed here. The bottom bracket 12 has multiple auxiliary oil chambers 14 inside. The number of auxiliary oil chambers 14 is the same as the number of load-bearing wheels 7. The first sealing plate 15 is vertically slidably connected inside the auxiliary oil chamber 14. The push rod 16 is fixedly connected to the lower side of the first sealing plate 15. The lower end of the push rod 16 extends to the lower side of the bottom bracket 12, and the load-bearing wheel 7 is rotatably connected to the lower end of the push rod 16. At this time, the height of the load-bearing wheel 7 can be adjusted by adjusting the height of the push rod 16.

[0025] Furthermore, the bottom support 12 is equipped with a main oil chamber 17 and multiple oil guide channels 20. The upper ends of the multiple bottom supports 12 are connected to the lower ends of the main oil chamber 17 through the oil guide channels 20. The main oil chamber 17 is filled with hydraulic oil. A pressurizing mechanism is installed on the bottom support 12 to pressurize the hydraulic oil, thereby pushing the hydraulic oil into the interior of the first sealing plate 15. Under the action of the hydraulic oil flow, the pressure inside the multiple drive wheels 4 will be the same, thereby pushing the multiple push rods 16 to descend. Since the push rods 16 are pushed by hydraulic pressure, when the multi-terrain tracked walking device travels on uneven ground, the multiple load-bearing wheels 7 can push the track body 11 to abut against the ground, thereby enabling the multiple load-bearing wheels 7 to bear the load, reducing the concentration of gravity and making the gravity evenly distributed.

[0026] Among them, such as Figures 3-4 As shown, the pressurizing mechanism includes a second hydraulic cylinder 19 fixedly connected to the upper side of the bottom bracket 12. The piston rod of the second hydraulic cylinder 19 extends into the main oil chamber 17 and is fixedly connected to a second sealing plate 18. By starting the second hydraulic cylinder 19, the second sealing plate 18 is driven to move downward, thereby pressurizing the hydraulic oil inside the main oil chamber 17 downward.

[0027] Furthermore, a pressure detection device, such as a pressure sensor, can be installed on the lower side inside the main oil chamber 17. The pressure detection device is electrically connected to a controller. The first hydraulic cylinder 8 and the second hydraulic cylinder 19 are both electrically connected to the controller. When the pressure detection device detects that the oil pressure inside the main oil chamber 17 is low, the controller can control the first hydraulic cylinder 8 to drive the second guide wheel 6 to move, thereby reducing the tension on the track belt 11. At the same time, the controller controls the second hydraulic cylinder 19 to push the second sealing plate 18 downward, thereby increasing the tension on the track belt 11.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
