Abstract
Description
Technical Field
[0001] This utility model relates to the field of robotics, and in particular to a rope-driven snake robot with an omnidirectional mobile lifting platform. Background Technology
[0002] Currently, the most common lifting platforms on the market are scissor lifts and aluminum alloy lifts. The former mainly relies on hydraulic power to drive the scissors for lifting, while the latter relies on belt drive to move the aluminum alloy bars in a staggered manner, thereby lifting the platform. Although these two types of lifting platforms can provide a large load capacity and lifting distance, their platform dimensions tend to be standard, mainly used for lifting operators and some special equipment. They are not specifically designed for snake-like robots and cannot be used in various working conditions and operating environments.
[0003] Snake-like robotic arms, modeled after the biological snake, possess advantages such as high flexibility, high redundancy, and small cross-sectional area, enabling them to operate in confined, complex, and high-risk environments, and have experienced rapid development in recent years. In current technologies, the moving arm of a snake-like robotic arm is mounted on a general-purpose or specially designed mobile platform. The combined movement of the mobile platform and the robotic arm achieves propulsion and obstacle avoidance in narrow spaces. However, this method, due to the large range of motion of the pushing platform, often requires a large workspace to house the mobile platform, hindering the practical application of snake-like robotic arms. Furthermore, because the pushing platform and the snake-like robotic arm are designed separately, the snake-like robotic arm is usually in an extended state when not in operation, occupying a significant amount of space and posing a disadvantage to the structural protection of the snake-like robotic arm itself. Utility Model Content

Suitable for retractable snake-like robotic arms, it offers vertical lifting and adjustable platform angles, enabling the snake-like robot to operate from multiple angles to meet specific work requirements. By integrating the snake-like robotic arm with the pushing platform, the arm can retract within the platform, improving the space utilization of the entire system. Furthermore, the omnidirectional lifting platform enhances the snake-like robot's flexibility and maneuverability.

The two base plates 6.4 are fixedly connected to the main housing 6.1 to form a closed box, which serves as the housing of the rope drive mechanism. An opening is provided on the main housing 6.1, and the serpentine robotic arm connector 6.2 is located in the opening, extending out of the rope drive mechanism. The outer shell is then connected to the serpentine robotic arm 7, which is coiled between two outer shell base plates 6.4.

Inside the rope driving mechanism, a wire groove base 6.5 is provided on one of the outer shell base plates 6.4, and the rope driving device is provided on the wire groove base 6.5.
[0047] The rope drive device includes a rope groove 6.6, a groove drive motor 6.7, and ropes. Fifteen grooves are provided on the groove base 6.5, and each groove contains a rope groove 6.6. A groove drive motor 6.7 is provided on the upper part of each rope groove 6.6, and a rope is wound inside each rope groove 6.6. One end of the rope is connected to the groove drive motor 6.7 and driven by the groove drive motor 6.7. The fifteen ropes pass through the snake-shaped robotic arm connector 6.2 and are connected to the snake-shaped robotic arm 7, pulling and driving the snake-shaped robotic arm 7.
[0048] A schematic diagram of the structure of the snake-shaped robotic arm 7 is shown below. Figure 6 As shown, the serpentine robotic arm 7 includes serpentine robotic arm joints 7.1 and universal joints 7.2, forming a 10-DOF super-redundant serpentine arm.

[0049] In practical implementation, when the present invention is in its initial state, the bottom support 1 is supported by the Mecanum wheel 2, and the snake-shaped robotic arm 7 is coiled on the rope drive mechanism 6; when the present invention is in its working state, the Mecanum wheel 2 is driven to move the robot to the working position, and then the leg external drive device 4 is driven to unfold the leg device 3. The optimal rotation angle is 120°, and then the first electric push rod 3.9 is driven to drive the slider 3.7 to slide along the linear slide rail 3.6, thereby extending the leg device 3. Due to the effect of gravity, the support... The leg base 3.14 is perpendicular to the ground, thus fixing and supporting the robot. Then, the second electric push rod 5.6 is driven to lift the rope drive mechanism 6 upward, with a maximum lifting angle of 60°. After being lifted to the appropriate angle, the drive groove drive motor 6.7 is driven. Under the pull of the rope, the snake-shaped robotic arm 7 slowly detaches from the outer groove of the rope drive mechanism 6 and slowly extends outward from the initial coiled state. Through the cooperation of the snake-shaped robotic arm joint 7.1 and universal joint 7.2, it achieves flexible movement of 10 degrees of freedom.
[0050] In practical applications, if necessary, the rotating pair structure of the rotating lifting device 5 can be added according to actual needs to achieve the purpose of lifting to a higher distance. The number of snake-shaped robotic arm joints 7.1 and universal joints 7.2 can also be increased or decreased according to actual needs to improve the robot's flexibility or reduce the robot's cost.
