Description

Technical Field

[0001] This utility model relates to the field of robotics technology, specifically to a railway inspection robot. Background Technology

[0002] Railway inspection robots are intelligent robots equipped with artificial intelligence and Internet of Things technologies, specifically designed for railway line inspection. Their core functions include autonomous navigation, data collection, fault detection and identification, defect location, and fault early warning.

[0003] Patent publication number CN 214520224 U discloses a novel railway inspection robot, including a base block, a support column at the upper end of the base block, a motor at the upper end of the support column, a gear connected to the rotating shaft of the motor, a rack meshing on the gear, the rack being fixedly set in the inner wall of the groove of the fixed block, a rubber strip on the outer side of the fixed block, and sliding grooves on both sides of the fixed block, with sliding columns slidably set in the inner wall of the sliding grooves, the sliding columns extending out of the sliding grooves and connected to the base block, and the motor driving the gear to rotate.

[0004] To address the problem that existing inspection robots have a single height position, making it inconvenient to inspect points at different heights and greatly limiting the effectiveness of the robots, the current technology uses a motor to drive a gear, which in turn drives a rack to move up and down. This causes a fixed block on the rack to move the inspection mechanism body up and down, making it easy to change the height of the inspection mechanism body to adapt to inspection methods at different heights. However, the above device still has the problem that during use, the inspection mechanism body can only simply inspect railways in the horizontal direction, and it is difficult to inspect railways with a certain slope, thus limiting the applicability of the device.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0025] Example 1

[0026] like Figure 1-5 As shown, this utility model provides a railway inspection robot, including a vehicle body mechanism 1. A rotating mechanism 3 is provided on the top surface of the vehicle body mechanism 1, and an adjusting mechanism 4 is provided on the top surface of the rotating mechanism 3.

The output shaft of the servo motor 21 drives the bidirectional lead screw of the bidirectional lead screw 22 to rotate, which in turn causes the bidirectional lead screw 22 to drive the two slide bars 23 to move towards each other inside the slide groove 15 through the ball nuts at both ends. Then, the hydraulic telescopic rod 24 is adjusted according to the height of the rails, and then the stepper motor 25 is started. The output shaft of the stepper motor 25 drives the brush 26 to rotate, and the surface of the rails can be cleaned by the brush 26.

When needed, only the second servo motor needs to be activated. The output shafts of servo motors 35 and 36 drive turntable 37 to rotate inside the rotating groove 32 via rotating rod 34, thereby making the rotation of turntable 37 more stable. Then, the robot body 41 controls hydraulic rod 42 to drive connecting arm 45 to rotate. Then, the robot body 41 controls the extension and retraction of hydraulic rod 43 to control the rotation angle of connecting arm 46. Then, the robot body 41 controls hydraulic rod 44 to control the rotation angle of adjusting plate 47, thereby making the inspection mechanism body 48 on the bottom of adjusting plate 47 adapt to various terrains.

[0031] The working principle of this railway inspection robot will be explained in detail below.

The output shaft of the first servo motor 21 drives the bidirectional lead screw of the bidirectional lead screw component 22 to rotate, which in turn causes the bidirectional lead screw component 22 to drive the two sliding rods 23 to move towards each other inside the slide groove 15 through the ball nuts at both ends. Then, the hydraulic telescopic rod 24 is adjusted according to the height of the rail. Then, the stepper motor 25 is started, and the output shaft of the stepper motor 25 drives the brush 26 to rotate, so that the surface of the rail can be cleaned by the brush 26. Then, the second servo motor 35 is started, and the second... The output shaft of the servo motor 35 drives the turntable 37 to rotate inside the rotating groove 32 via the rotating rod 34, thereby making the rotation of the turntable 37 more stable. Then, the robot body 41 controls the first hydraulic rod 42 to drive the first connecting arm 45 to rotate. Then, the robot body 41 controls the extension and retraction of the second hydraulic rod 43 to control the rotation angle of the second connecting arm 46.
