[0030] Please refer to Figures 1-6 This utility model provides a specific embodiment of a miniature tracked wall-climbing inspection robot. For ease of explanation, it is described below. Figure 1 Based on this, the movement direction of the wall-climbing mechanism 11 is set to forward and backward.
[0031] like Figures 1-6 As shown, this utility model provides a miniature tracked wall-climbing inspection robot, including a wall-climbing mechanism 1, a detection mechanism 2 installed on the wall-climbing mechanism 1, and a control mechanism 3 for remotely controlling the movement of the wall-climbing mechanism 1;
[0032] The wall-climbing mechanism 1 includes a base frame 11, a left track drive module 12 and a right track drive module 13 respectively installed on the left and right sides of the base frame 11, and a magnet 14 installed at the bottom of the base frame 11 for adsorbing metal walls. The left track drive module 12 includes a first reduction motor 121 installed at the front end of the base frame 11, a first drive pulley 122 installed on the output shaft of the first reduction motor 121, a first driven pulley 124 installed at the rear end of the base frame 11, and a first track 123 sleeved on the first drive pulley 122 and the first driven pulley 124. The right track drive module 13 includes a second reduction motor 131 installed at the rear end of the base frame 11, a second drive pulley 132 installed on the output shaft of the second reduction motor 131, a second driven pulley 134 installed at the front end of the base frame 11, and a second track 133 sleeved on the second drive pulley 132 and the second driven pulley 134.
[0033] In this embodiment, after the first geared motor 121 receives a remote command and sends out current, the first drive pulley 122, coaxially connected to the output shaft of the first geared motor 121, begins to rotate. The track sleeved and connected to the first drive pulley 122 and the driven pulley located at the rear end of the base frame 11 also move accordingly. Simultaneously, after the second geared motor 131 receives a remote command and sends out current, the second drive pulley 132, coaxially connected to the output shaft of the second geared motor 131, begins to rotate. The track sleeved and connected to the second drive pulley 132 and the driven pulley located at the front end of the base frame 11 also move accordingly. When both the first track 123 and the second track 133 begin to move... The wall-climbing mechanism 1 begins to move. When the first motor and the second motor carry current in the same direction, the wall-climbing mechanism 1 can move forward or backward. When the current direction is opposite, the wall-climbing mechanism 1 can turn left or right. The speed of the wall-climbing mechanism 1 can be controlled by adjusting the magnitude of the current. By setting tracks with strong grip, the wall-climbing mechanism 1 has a strong ability to overcome obstacles, which improves its adaptability to complex structures. The magnet 14, which is generally a neodymium magnet, is set at the bottom of the base frame 11, which enhances the wall-climbing mechanism 1's ability to attract the metal inner wall of large equipment, effectively improving its wall-climbing ability and load capacity inside the equipment.
[0034] like Figure 4 As shown, the detection mechanism 2 includes a main handle 22, a camera transmission cable assembly, and an endoscope 21 installed at the front end of the wall-climbing mechanism 1; one end of the camera transmission cable assembly is connected to the endoscope 21, and the other end is connected to a camera control joystick 23; the rotation of the endoscope 21 is controlled by the camera control joystick 23.
[0035] In this embodiment, the camera drive cable assembly consists of four control cables (up, down, left, and right) that control the endoscopic camera 21 to swing up, down, left, or right, respectively. The four control cables are controlled by an external operator shaking the camera control joystick 23, thereby controlling the up, down, left, and right swing of the endoscopic camera 21. The up, down, left, and right swing of the endoscopic camera 21 enhances the external observer's judgment of the internal structure and terrain of the equipment. At the same time, the images recorded by the endoscopic camera 21 can be clearly read onto the monitor through remote operation, allowing the operator to make timely adjustments based on the real-time images. This not only ensures safety and reliability but also enhances the adaptability to complex environments.
[0036] like Figure 4 As shown, the camera transmission cable assembly is fitted with a flexible connecting rod 24, which is fixedly mounted on the base frame 11 by a fixing bracket 16.
[0037] In this embodiment, the flexible connecting rod 24 is mainly used to protect the camera transmission line assembly. The flexible connecting rod 24 is a flexible component that can be bent. The flexible connecting rod 24 is fixedly installed on the base frame 11 of the wall climbing mechanism 1. When the location to be detected is deep or complex, the flexible connecting rod 24 can be extended and bent as needed. In conjunction with the movement of the wall climbing mechanism 1, the endoscope 21 at its top can be clearly detected.
[0038] like Figures 2-3 As shown, multiple drive wheels 15 for supporting and guiding the tracks are meshed on the lower drive surfaces of the first track 123 and the second track 133.
[0039] In this embodiment, the multiple transmission wheels 15 are mainly used to support the movement of the first track 123 and the second track 133, so that the first track 123 and the second track 133 can move better, and the movement of the climbing mechanism 1 is smoother.
[0040] like Figures 5-6 As shown, the control mechanism 3 includes a control box housing 31, a display bracket 32 fixedly mounted on the upper part of the control box housing 31, and a control component 33 disposed inside the control box housing 31; the control box housing 31 has an observation hole 34 on its side wall; the control component 33 includes a battery 331 and an Arduino board 332 and a voltage regulator module 333 fixedly mounted on the inner wall of the control box housing 31; a support bar 334 for supporting the battery 331 is disposed on the inner bottom surface of the control box housing 31; a climbing mechanism operation joystick 35 for controlling the movement of the climbing mechanism 1 is disposed on the display bracket 32, and the climbing mechanism operation joystick 35 controls the movement trajectory of the climbing mechanism 1 through the information transmission of the control component 33.
[0041] In this embodiment, the control mechanism 3 is mainly used to control the movement trajectory of the climbing mechanism 1. The pre-written code is written into the Arduino board 332, so that the climbing mechanism operation joystick 35 can control the direction and magnitude of the current of the first motor and the second motor in the climbing mechanism 1 according to the code, thereby realizing the control of the climbing mechanism 1 to move forward, backward, turn left, and turn right by the climbing mechanism operation joystick 35. There can be two climbing mechanism operation joysticks 35, one of which controls forward or backward movement, and the other controls left or right turn. When the output current of a certain mechanism is too large, the voltage regulator module 333 can control the output voltage within a certain range to ensure the overall operation of the robot. A support bar 334 is set below the battery 331, which is mainly used to fix and protect the battery 331 to prevent the battery 331 from colliding with the control box shell 31 during the operation of the control mechanism 3. The display bracket 32 is mainly used to place the display and communicate with the endoscope camera 21 through a remote wireless connection to provide real-time feedback of the images captured by the camera. The observation hole 34 is mainly used to observe the inside of the control box, so that the situation inside the control box can be detected in time.
[0042] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention. Obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
