An efficient drive apparatus for a robot

Abstract

This utility model discloses a high-efficiency drive device for robots, relating to the field of robot technology. It includes a chassis on which a drive motor is mounted. A reducer is connected to the output end of the drive motor, and a rotating shaft is fixedly connected to the output end of the reducer. A first bevel gear is fixedly connected to the rotating shaft, and a second bevel gear is meshed with one side of the first bevel gear. An axle is fixedly connected inside the second bevel gear, and a movable wheel is fixedly mounted on the axle. This utility model allows the drive motor to move the movable wheel, enabling the device to move forward and backward. Conversely, a driver moves a translation wheel downward, lifting it off the ground. A dual-axis motor then drives the translation wheel to rotate, allowing the device to quickly translate along a direction perpendicular to the direction of movement when needed, improving the device's flexibility. The combined use of the translation wheel and the movable wheel results in high drive efficiency.

Description

Technical Field

[0001] This utility model relates to the field of robot technology, specifically a high-efficiency drive device for robots. Background Technology

[0002] Industrial inspection robots are automated devices specifically designed to perform inspection tasks in industrial environments. They can replace or assist manual labor in completing repetitive, hazardous, or precision-critical inspection tasks. These robots are widely used in the inspection of facilities and equipment in industries such as power, petroleum, chemical, and mining.

[0003] Traditional inspections typically employ manual inspections and fixed-point monitoring with cameras. Manual inspections are inefficient and lack quality assurance. Fixed-point monitoring with cameras has a limited monitoring range, requires the deployment of numerous cameras, resulting in a large workload for image monitoring and storage, extensive installation and wiring, and challenging maintenance, leading to very low overall efficiency.

[0004] For inspection robots, a drive device is needed to propel the robot back and forth along a fixed route to complete inspection tasks. The flexibility of existing drive devices needs improvement; therefore, this invention proposes a high-efficiency drive device for robots. Summary of the Invention

[0005] Technical problems to be solved

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-efficiency drive device for robots.

[0007] Technical solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency drive device for a robot, comprising a chassis, a drive motor mounted on the chassis, a reducer connected to the output end of the drive motor, a rotating shaft fixedly connected to the output end of the reducer, a first bevel gear fixedly connected to the rotating shaft, a second bevel gear meshing with one side of the first bevel gear, an axle fixedly connected inside the second bevel gear, and a movable wheel fixedly mounted on the axle. By setting up a chassis and installing the drive motor, reducer, rotating shaft, first bevel gear, second bevel gear, axle, and movable wheel in the chassis, the movable wheel can be moved by the drive motor during use, thereby enabling the device to move forward and backward.

[0009] Fixed rods are also fixedly installed at the four corners of the chassis. Liftable supports are installed inside the fixed rods. Rotatable translation wheels are installed at both ends of the supports. A driver is connected to the center of the supports. The driver is fixed to the chassis, and its output end is fixedly connected to the supports. A dual-axis motor is fixedly installed inside the supports. The output ends of the dual-axis motor are connected to drive rods via a second reducer. The end of the drive rod away from the second reducer is fixedly connected to the translation wheel. The arrangement of the fixed rods, supports, translation wheels, driver, dual-axis motor, second reducer, and drive rods allows the device to move the translation wheel downwards and lift it off the ground when needed via the driver. Then, the dual-axis motor can drive the translation wheel to rotate, enabling the device to quickly move along a direction perpendicular to the direction of movement when needed. This improves the flexibility of the device. The translation wheel and the translation wheel work together for high driving efficiency.

[0010] Preferably, the translation wheels are rotatably mounted at both ends of the bracket via bearings.

[0011] Preferably, the fixing rod has a groove inside for mounting the bracket, and a guide rod is fixedly connected inside the groove.

[0012] Preferably, the bracket has a guide hole inside that matches the guide rod.

[0013] Preferably, each of the axles is provided with multiple movable wheels.

[0014] Preferably, there are several first bevel gears on the rotating shaft.

[0015] Preferably, the actuator is one of an electric telescopic rod, a cylinder, or a hydraulic rod.

[0016] Beneficial effects:

[0017] Compared with existing technologies, this efficient drive device for robots has the following advantages:

[0018] This invention features a chassis in which a drive motor, reducer, shaft, first bevel gear, second bevel gear, axle, and moving wheel are installed. During use, the drive motor moves the moving wheel, enabling the device to move forward and backward. Furthermore, the device incorporates a fixed rod, bracket, translation wheel, driver, dual-axis motor, reducer, and drive rod. When needed, the driver can lower the translation wheel, lifting it off the ground. The dual-axis motor then rotates the translation wheel, allowing the device to quickly move perpendicular to its direction of travel, thus improving its flexibility. The combined use of the translation wheel and moving wheel ensures high driving efficiency. Attached Figure Description
