[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model discloses a tracked chassis that, during operation, can be configured with a single-piece or two-piece working mode by including a walking component I, a walking component II, and a limiting assembly. When the device moves on flat ground, the chassis operates as a single piece, resulting in smoother movement.

[0022] The track assembly includes a traveling component I2 and a traveling component II3. Traveling component I2 is fixedly connected to the side of the connecting bracket 1, and traveling component II3 is rotatably mounted on the side of the connecting bracket 1, forming a rotating pair on the side of the connecting bracket 1. A limiting component 4 is provided between traveling component I2 and traveling component II3. By providing the limiting component 4, traveling component I2 and traveling component II3 can be a single unit or separated into two individual parts.

[0023] In a preferred embodiment, the connecting bracket 1 is composed of a support frame consisting of round rods and square rods in the middle, the walking component I2 is fixedly installed at the end of the square rod, and the walking component II3 is rotatably installed at the end of the round rod.

[0024] In a preferred embodiment, the walking component I2 includes a fixed bracket 21 and a load-bearing wheel I22. The fixed bracket 21 is fixedly connected to the side of the connecting bracket 1, thereby forming a rigid support between the fixed bracket 21 and the connecting bracket 1. The load-bearing wheel I22 is rotatably mounted below the fixed bracket 21. The load-bearing wheel I22 is responsible for supporting the weight of the vehicle and ensuring the stability of the vehicle on the ground.

[0025] In a preferred embodiment, the walking component II 3 includes a movable support 31, a load-bearing roller II 32, an auxiliary roller 33, and a tensioning roller 34. The movable support 31 is rotatably mounted on the side of the connecting support 1, forming a rotating pair on the side of the connecting support 1. The load-bearing roller II 32 is rotatably mounted below the movable support 31, while the auxiliary roller 33 is rotatably mounted above it. The auxiliary roller 33 helps guide the track along a predetermined trajectory, thereby ensuring that the track does not deviate during operation. The tensioning roller 34 is rotatably mounted on the side of the movable support 31. The tensioning roller 34 can be adjusted to increase or decrease the tension of the track, thereby ensuring that the track does not loosen or fall off during operation.

[0026] In a preferred embodiment, the track assembly further includes tracks 5 and a motor gearbox 6. The tracks 5 on the outer sides of the traveling components I2 and II3 on ​​the same side are wrapped around the load-bearing rollers I22, II32, auxiliary rollers 33, and tension rollers 34. The motor gearbox 6 is located on both sides of the connecting bracket 1 and inside the two tracks 5, and is powered by the tracks 5.

The movable pin 42 can be inserted into the pin groove 43.

[0029] The working principle of this utility model:

[0030] When the device moves on flat ground, the movable pin 42 is driven by the hydraulic cylinder 41 to insert into the pin slot 43, so that the walking component I2 and the walking component II3 form a whole, and then the walking chassis is driven to move by the motor gearbox 6.

[0031] When one side of the device encounters an obstacle, the hydraulic cylinder 41 on that side drives the movable pin 42 to leave the pin slot 43, causing the walking component I2 and the walking component II3 to separate. At this time, the walking component II3 will rotate when it encounters an obstacle. After the walking chassis passes the obstacle, the hydraulic cylinder 41 drives the movable pin 42 to insert into the pin slot 43, so that the walking component I2 and the walking component II3 form a whole.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
