The walking mechanism provided by the application can be used on various types of tool equipment and used for realizing walking and lifting of the equipment. A typical apparatus is a cutting machine, and the following takes the cutting machine as an example to specifically describe the traveling mechanism provided in the present application.

In a specific cutting machine structure, the cutting machine is powered by an automatic diesel engine, a main shaft of the engine drives a gearbox through an electromagnetic clutch, and the gearbox drives a saw blade to perform cutting operation through belts on two sides. In addition, a power take-off port on the engine is provided with a hydraulic pump for driving the rear wheels to run and the front wheels to lift.

Referring to fig. 1 to 3, an embodiment of the present application provides a liftable traveling mechanism, including: main girder 10, rear axle 20, front axle 30, drive element 40. Rear axle 20 has rear wheels 21 and front axle 30 has front wheels 31, so that it can be used for walking movements.

Specifically, the running mechanism further includes a power source for driving the rear wheels 21 to rotate. Under the drive of the power source, the rear wheel 21 starts to rotate, and the whole travelling mechanism is driven to advance. The number of front wheels 31 and rear wheels 21 can be set according to the actual situation, and in a specific example, the number of rear wheels 21 is 2, and the number of front wheels 31 is 1. In a specific example, the number of rear wheels 21 is 1 and the number of front wheels 31 is 2. In a specific example, the number of rear wheels 21 is 2 and the number of front wheels 31 is 2.

The front axle 30 includes a front wheel 31, and a link member 32. The link member 32 is rotatably connected to the main beam 10, and the front wheel 31 is rotatably connected to the link member 32. The driving element 40 is connected to the main beam 10 and the link member 32 respectively, and is used for driving the link member 32 to rotate relative to the main beam 10, so as to lift or lower one end of the main beam 10.

Further, the driving element 40 is a telescopic member, for example, the driving element 40 is a pneumatic element, a hydraulic element, or an electric element. In a specific example, the drive element 40 is embodied as a hydraulic cylinder. The driving element 40 is connected to the main beam 10 at one end and to the link member 32 at the other end, and when the driving element 40 extends and contracts to change the length, the link member 32 rotates relative to the main beam 10, so that one end of the main beam 10 is raised or lowered. Referring to fig. 1, when the front wheel 31 of the front axle 30 is grounded, the link member 32 rotates clockwise when the driving element 40 is extended, the front axle 30 supports the main beam 10, the main beam 10 rotates counterclockwise, and the front end of the main beam 10 near the side of the front axle 30 is lifted upward. When the driving element 40 is contracted, the link member 32 rotates counterclockwise, the main beam 10 rotates clockwise, and the front end of the main beam 10 near the front axle 30 side moves forward, decreasing the height. Therefore, the height of the front end of the main beam 10 can be controlled by controlling the extension and contraction of the driving element 40. When the driving element 40 is automatically extended and retracted under the control of the controller, the main beam 10 can automatically swing up and down, and the front end of the main beam can automatically lift up and down.

In one embodiment, front axle 30 includes a front axle 33, and one front wheel 31 is mounted at each end of front axle 33; the link member 32 is connected to the front axle 33, and is rotatably connected to the front wheel 31 via the front axle 33.

A plurality of link members 32 are arranged along the axial direction of the front axle 33, and the plurality of link members 32 are rotatably connected to the main beam 10 by the same hinge shaft 34. It should be noted that the link members 32 and the main beam 10 can be directly connected together, or can be connected together by connecting components, and no matter what connection method is adopted, it should be ensured that the link members 32 and the main beam 10 can rotate relatively.

Further, the number of link members 32 is not necessarily large, and the number of driving elements 40 is not necessarily large, and the driving elements 40 may be provided only in a part of the link members 32. Referring to fig. 3, 2 link members 32 are arranged along the axial direction of the front axle 33, and a drive element 40 is provided between only one of the link members 32 and the main beam 10, and the entire front axle 30 is driven by driving one of the link members 32. Therefore, the driving elements 40 may or may not correspond to the link members 32 one by one, and the driving elements 40 are provided only on a part of the link members 32. Further, it should be understood that the link member 32 need not be a rod-like structure.

Referring to FIG. 1, in one embodiment, the diameter of the rear wheel 21 is greater than the diameter of the front wheel 31. The rear wheels 21 are driving wheels for power output and steering.

In some embodiments, rear axle 20 further includes a rear axle 22, and one rear wheel 21 is mounted at each end of rear axle 22. Under the drive of the power source, the rear wheel 21 can rotate automatically and is used as a driving wheel to drive the whole travelling mechanism to move forwards or backwards. The power source may be an internal combustion engine, an electric motor, or the like. Additionally, in some embodiments, rear axle 20 may also be used for steering.
