The folding cylinder is used to adjust the distance between two track assemblies at the same end of the chassis.

[0005] Preferably, a first support rod and a second support rod are provided between the support beam and the track assembly. The two ends of the first support rod are respectively hinged to the support beam and the track assembly, and the two ends of the second support rod are respectively hinged to the support beam and the track assembly. A first luffing cylinder is hinged between the first support rod and the second support rod.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] See attached document Figure 1 and attached Figure 2 This embodiment provides a walking device suitable for confined spaces, including a chassis 1. Support beams 2 are rotatably mounted at both the front and rear ends of the chassis 1. There are four support beams 2 in total, with two distributed at each end of the chassis 1. The two support beams 2 at each end of the chassis 1 can open or close, thereby adjusting the distance between two track assemblies 3 at the same end of the chassis 1. Track assemblies 3 are located below the support beams 2, and a first amplitude-adjusting mechanism 4 is provided between the support beams 2 and the track assemblies 3. The first amplitude-adjusting mechanism 4 is used to adjust the distance between the track assemblies 3 and the chassis 1. (See attached figure.) Figure 3 When the track assembly 3 extends outward, the width or length of the walking device increases, which helps maintain a stable center of gravity and provides a safer operating environment for the robotic arm. (See attached diagram.) Figure 4 When the track assembly 3 retracts, the width or length of the walking device decreases, which is beneficial for passing through narrow spaces. A folding cylinder 5 is provided between the chassis 1 and the track assembly 3 or between the chassis 1 and the support beam 2. The distance between the two support beams 2 at the same end of the chassis 1 is adjusted by the folding cylinder 5, thereby adjusting the distance between the two track assemblies 3 at the same end of the chassis 1. This utility model drives the track assembly 3 to extend outward or retract inward through the first amplitude-changing mechanism 4, thereby adjusting the width or length of the walking device. The folding cylinder 5 drives the two track assemblies 3 at the same end of the chassis 1 to open or close, which can further adjust the width or length of the walking device. When the track assembly 3 retracts inward, it is convenient for the walking device to pass through narrow spaces; when the track assembly 3 extends outward, it is convenient to maintain the stability of the center of gravity during operation.

[0025] One embodiment of the first luffing mechanism 4: A first support rod 41 and a second support rod 42 are provided between the support beam 2 and the track assembly 3. The two ends of the first support rod 41 are hinged to the support beam 2 and the track assembly 3, respectively. The two ends of the second support rod 42 are also hinged to the support beam 2 and the track assembly 3, respectively. A first luffing cylinder 43 is hinged between the first support rod 41 and the second support rod 42. The hinge points between the first support rod 41 and the first luffing cylinder 43, the hinge points between the first support rod 41 and the track assembly 3, and the first luffing cylinder 43 are also connected. The hinge points between the luffing cylinder 43 and the track assembly 3 form the three vertices of a triangle. The hinge points between the second support rod 42 and the first luffing cylinder 43, the second support rod 42 and the support beam 2, and the second luffing cylinder and the support beam 2 also form the three vertices of a triangle. Through this structural design, the first luffing mechanism 4 can form a stable support structure between the support beam 2 and the track assembly 3. Furthermore, the extension or retraction of the track assembly 3 can be adjusted by the extension and retraction of the first luffing cylinder 43.

[0026] In another embodiment of this utility model, the first support rod 41 is parallel to the second support rod 42.

[0027] In another embodiment of this utility model: a first shaft 44 is fixed on the support beam 2, and the first support rod 41 and the first luffing cylinder 43 are rotatably connected to the first shaft 44. A second shaft 45 is fixed on the track assembly 3, and the second support rod 42 and the first luffing cylinder 43 are rotatably connected to the second shaft 45.

[0028] Specifically, the first support rod 41, the second support rod 42, and the first luffing cylinder 43 are all located between the two track assemblies 3 at the same end of the chassis 1.

[0029] In another embodiment of this utility model: the second support rod 42 is a second variable amplitude hydraulic cylinder, as shown in the attached drawing. Figure 5 The second variable-amplitude cylinder drives the track assembly 3 to rotate around the first shaft 44, thereby adjusting the angle between the track assembly 3 and the horizontal plane, making it easier to climb over obstacles, such as stairs.

[0030] As another embodiment of this utility model: the lower end of the support beam 2 is provided with a receiving groove, and the upper ends of the second support rod 42 and the first luffing cylinder 43 both extend into the receiving groove. During operation, the upper receiving groove can protect the second support rod 42 and the first luffing cylinder 43.

[0031] In another embodiment of this utility model: a third shaft 46 is fixed on the track assembly 3, the first support rod 41 is rotatably connected to the third shaft 46, and a connecting rod 47 is fixed between the third shaft 46 and the second shaft 45.

[0032] As another embodiment of the present invention: the chassis 1 is provided with mounting grooves 11 at both the front and rear ends, one end of the folding cylinder 5 is installed in the mounting groove 11, and the other end of the folding cylinder 5 is installed on the track assembly 3.

[0033] One embodiment of the folding cylinder 5: The folding cylinder 5 is connected to the second shaft 45 through the first hinge shaft. The folding cylinder 5 swings left and right around the first hinge shaft and swings up and down around the second shaft 45. In this structural design, the folding cylinder 5 can support the track assembly 3 while driving the support beam 2 to swing left and right.

[0034] Another implementation of the folding cylinder 5: The two ends of the folding cylinder 5 are connected to the chassis 1 and the track assembly 3 respectively by ball joints.

[0035] The third implementation of the folding cylinder 5: The two ends of the folding cylinder 5 are hinged to the chassis 1 and the support beam 2 respectively. This design is simple in structure, but compared with the first two methods, it cannot provide support for the track assembly 3.

[0036] As another embodiment of this utility model: the upper end of the track assembly 3 is provided with a protective shell 31, which can effectively protect the track, drive wheel, driven wheel and other components.

[0037] As another embodiment of this utility model: the chassis 1 is provided with a rotating hole 12 to provide space for the installation of the rotating base.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
