Description

Technical Field

[0001] This utility model relates to the field of inspection robot technology, and in particular to an anti-tipping device for an inspection robot. Background Technology

[0002] With the increasing intelligence and automation of industry, inspection robots are being used more and more widely in complex environments such as power, petrochemical, and warehousing. These robots need to move autonomously in terrains such as narrow passages, slopes, and steps, while carrying high-definition cameras, sensors, and other precision equipment to complete inspection tasks. However, when facing uneven, slippery working surfaces, they are prone to tipping over due to a shift in center of gravity and insufficient grip. Existing anti-tipping devices for inspection robots have a small contact area and support span with the ground when the robot encounters sudden external interference, resulting in insufficient anti-tipping ability and reduced stability. Furthermore, when the support components experience wear, mechanical failure, or component damage after long-term use, it is inconvenient to remove the damaged support components, leading to low maintenance convenience.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-5 The present invention provides an embodiment of an anti-tipping device for an inspection robot, comprising a base 1 that can be installed under the robot, a control component 22 connected to the bottom of the base 1, and a support component 2 for improving stability and maintenance convenience connected inside the base 1.

[0030] The support assembly 2 includes a motor 3 and a connecting plate 4. The motor 3 is fixedly installed on the outside of the base 1 by bolts. One end of the connecting plate 4 is fixedly connected to the top of the base 1. A connecting rod 5 is rotatably connected inside the connecting plate 4. One end of the connecting rod 5 passes through the base 1 and is fixedly connected to the output shaft of the motor 3. One end of the connecting rod 5 rotates inside the base 1. The other end of the connecting rod 5 is fixedly connected to a driving bevel gear 6. A driven bevel gear 7 is meshed on one side of the driving bevel gear 6. The top of the driven bevel gear 7 is rotatably connected to the top of the base 1.

[0031] Support assembly 2 also includes a threaded rod 8, one end of which is fixedly connected to the bottom of the driven bevel gear 7, and the other end of which rotates at the bottom of the base 1. An active plate 9 is threadedly connected to the outside of the threaded rod 8, and a slider 11 is fixedly connected to the outside of the active plate 9. A groove 10 is provided on the side of the base 1, and one end of the slider 11 passes through the groove 10 and slides inside it, ensuring the movement path of the slider 11. Support assembly 2 also includes a limiting plate 12, the rear end of which is fixedly connected to one end of the slider 11, and a mounting plate 13 is fixedly connected to the front end of the limiting plate 12. A guide groove 14 is provided inside the limiting plate 12, and a guide block 15 is slidably connected inside the guide groove 14. One end of the guide block 15 passes through the guide groove 14 and is fixedly connected to a mounting plate 16, allowing adjustment of the position of the mounting plate 16 and improving the fixation. In addition, the support assembly 2 also includes a mounting plate 3 17, one end of which is fixedly connected to a support leg 21. Mounting holes 18 are opened inside the mounting plate 3 17, mounting plate 13, and mounting plate 2 16. A screw 19 is slidably connected inside the mounting hole 18, and a nut 20 is threadedly connected to the outside of the screw 19 for easy disassembly and installation. The control assembly 22 includes a controller 23 and a tilt sensor 24. The controller 23 and the tilt sensor 24 are both connected to the bottom of the base 1, which can start the support assembly 2 in time. The controller 23, the tilt sensor 24, and the motor 3 are electrically connected. A protective shell 25 is fixedly installed on the bottom of the base 1 by bolts. The protective shell 25 is located outside the controller 23 and the tilt sensor 24, which improves the protection performance. Multiple sets of pulleys 26 are connected to the bottom of the base 1.

[0032] Working principle: When the inspection robot moves in the work area on the pulleys 26, the tilt sensor 24 installed at the bottom of the base 1 monitors the robot's posture changes in real time and continuously transmits data such as tilt angle and acceleration to the controller 23. Once the robot encounters sudden external interference such as strong wind, collision or sudden terrain change, and the tilt angle detected by the tilt sensor 24 exceeds the preset threshold, the controller 23 immediately sends a start command to the motor 3. After receiving the signal, the output shaft of the motor 3 drives the connecting rod 5 fixed to it to rotate, which in turn drives the active bevel gear 6 to rotate. The active bevel gear 6 transmits power to the driven bevel gear 7 through meshing transmission. The driven bevel gear 7 drives the threaded rod 8 connected to the bottom to rotate synchronously. As the threaded rod 8 rotates, the threaded connection with it... Guided by the slider 11 and the slide groove 10, the active plate 9 moves smoothly downward along the axis of the threaded rod 8, simultaneously driving the limit plate 12, mounting plate one 13, mounting plate two 16 and mounting plate three 17 to descend synchronously, allowing the support leg 21 to quickly extend and touch the ground. By increasing the contact area with the ground and the support span, the robot's center of gravity is effectively lowered, external force interference is offset, and tipping accidents are avoided. When the support assembly 2 wears or malfunctions due to long-term use, maintenance personnel can unscrew the nut 20, pull out the screw 19, and quickly separate the mounting plate one 13, mounting plate two 16 and mounting plate three 17 to remove the damaged support leg 21. Subsequently, the new support leg is re-fixed to the nut 20 through the mounting hole 18 with the screw 19, completing the quick replacement.

[0033] All electrical components mentioned in this article are electrically connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and known components is omitted in the specific embodiments disclosed herein. To ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

The structural technology of inspection robots is already very mature and has been widely used. Inspection robots are common knowledge in this field and will not be elaborated here. At the same time, this application does not protect the specific structure of the inspection robot.
