[0010] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0011] In the description of the embodiments of the present invention, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0012] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0013] In the description of the embodiments of the present invention, "multiple" means at least two.

[0014] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0015] Example:

[0016] Combined with appendix Figure 1-5 This embodiment discloses a stair-climbing machine, including a chassis 1. Tracked walking mechanisms 2 are arranged on both sides of the chassis 1, and a scissor-lifting mechanism 3 is arranged on the upper part of the chassis 1. The tracked walking mechanism and the scissor-lifting mechanism can be selected from mature products in the prior art according to specific needs. A load-bearing top plate 4 is slidably arranged on the top of the scissor-lifting mechanism 3. A hydraulic push rod mechanism is arranged between the top of the scissor-lifting mechanism 3 and the load-bearing bottom plate, so that the load-bearing top plate 4 can move back and forth along the top of the scissor-lifting mechanism 3. Hydraulic telescopic columns 5 are respectively arranged at the front and rear ends of the bottom of the chassis 1. Universal walking wheels 6 are arranged at the bottom of the hydraulic telescopic columns 5. When the hydraulic telescopic columns 5 extend downward, the universal walking wheels 6 contact the ground, suspending the tracked walking mechanism 2. When the hydraulic telescopic columns 5 retract upward, the universal walking wheels 6 suspend the tracked walking mechanism 2 in contact with the ground.

[0017] The top plate 4 is snapped onto the top of the scissor lift mechanism 3. The hydraulic push rod mechanism includes a hydraulic push rod 7 arranged parallel to the walking direction of the tracked walking mechanism on the top of the scissor lift mechanism 3. The extended end of the hydraulic push rod 7 is connected to the bottom of the top plate 4 through a push block 8, and the other end is connected to the top of the scissor lift mechanism 3 through a mounting bracket 9. Several support columns 10 are arranged upward on the end of the scissor lift mechanism 3 away from the moving seat 9. The top of the support columns 10 is rotatably connected to a support wheel 11 that contacts the inner bottom surface of the top plate 4. Slide rails 12 are also provided on both sides of the scissor lift mechanism 3, and a slider bar 13 that is slidably connected to the slide rails 12 is provided at the bottom of the top plate 4.

[0018] An anti-slip pad 16 is provided on the upper part of the supporting top plate 4. The anti-slip pad 16 has several anti-slip patterns that are perpendicular to the moving direction of the supporting top plate 4.

[0019] One end of the chassis 1 is equipped with a control box and a battery 14 connected to a tracked walking mechanism 2, a scissor lift mechanism 3, a hydraulic telescopic column 5, and an electric screw 7; the chassis 1 is equipped with multiple drive motors 17 of the tracked walking mechanism 2 inside, and several handles 15 are provided at the end of the chassis 1 away from the control box and battery box 14.

[0020] In practice, the load can be fixed to the upper part of the supporting top plate. By driving the hydraulic push rod mechanism, the horizontal position of the supporting top plate in the stair climber can be adjusted, and the position of the load can be adjusted. By driving the scissor lift mechanism, the height of the supporting top plate can be adjusted, thereby adjusting the height of the load. Then, by driving the crawler walking mechanism, the stair climbing operation can be performed. When encountering a corner, the hydraulic telescopic column is extended, so that the universal walking wheels contact the ground. At this time, the operator rotates the stair climber to turn to the next step, and then drives the hydraulic telescopic column to retract, so that the crawler walking mechanism contacts the ground, and the stair climbing to the next step can proceed.

[0021] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
