Description

Technical Field

[0001] This utility model relates to the field of inspection robot technology, specifically a locking structure for the traveling device of an inspection robot. Background Technology

[0002] Inspection robots are intelligent devices with autonomous movement, sensing, monitoring, and data collection capabilities. They are specifically designed to replace or assist humans in inspecting and patrolling specific areas, equipment, or environments. Inspection robots are typically equipped with a variety of sensors, such as cameras, infrared sensors, lidar, temperature sensors, and humidity sensors, which can acquire images, sounds, temperature, humidity, and other information about the surrounding environment in real time and analyze and process this data through built-in intelligent algorithms.

[0003] During the use of inspection robots, there will be specific positions or situations where they need to stop or remain stationary. In some working environments where high positional accuracy is required, the locking structure of the traveling device is particularly important. Therefore, we propose a locking structure for the traveling device of an inspection robot. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 3 This utility model provides a technical solution: a locking structure for a patrol robot's traveling device, including a chassis 1, a plurality of brackets 2 fixedly connected to the bottom of the chassis 1, an axle 3 rotatably connected to the internal bearing of the bracket 2, a brake wheel 4 fixedly connected to the outer side of the axle 3, a first collar 12 sleeved on the outer side of the axle 3, a second collar 14 sleeved on the outer side of the axle 3, a second connecting block 13 fixedly connected to the outer side of the first collar 12, a first rotating rod 11 rotatably connected to the inside of the second connecting block 13 via a rotating shaft, an mounting block 5 fixedly connected to the bottom of the chassis 1, a connecting seat 9 slidably connected to the outer side of the mounting block 5, two corresponding first connecting blocks 10 fixedly connected to the outer side of the connecting seat 9, and one end of the first rotating rod 11 rotatably connected to the inside of the first connecting block 10 via a rotating shaft;

[0021] The mounting block 5 has a T-shaped groove 6 inside, and a T-shaped slider 7 is slidably connected inside the T-shaped groove 6. The T-shaped slider 7 is fixedly connected to the connecting seat 9. An electric telescopic rod 8 is fixedly installed at the bottom of the chassis 1. The output end of the electric telescopic rod 8 is fixedly connected to the T-shaped slider 7. Through the cooperation of the electric telescopic rod 8 and the T-shaped slider 7, the connecting seat 9 can be moved, thereby pushing the first rotating rod 11 to move through the two first connecting blocks 10, thereby pushing the two second connecting blocks 13, and then pushing the two first collars 12 to move accordingly.

[0022] Two corresponding fourth connecting blocks 17 are fixedly connected to the outer side of the first ring 12, and two corresponding third connecting blocks 15 are fixedly connected to the outer side of the second ring 14. A push rod 16 is rotatably connected inside the third connecting block 15 through a rotating shaft, and one end of the push rod 16 is rotatably connected to the inside of the fourth connecting block 17 through a rotating shaft.

[0023] The second ring 14 has two corresponding insertion slots 21 inside. Insertion rods 20 are inserted into the insertion slots 21. An arc block 18 is fixedly connected to one side of the insertion rod 20. A brake disc 19 is fixedly connected to one side of the arc block 18. A brake seat 25 is fixedly connected to the outside of the axle 3. The brake disc 19 and the brake seat 25 cooperate with each other.

[0024] The second ring 14 has multiple positioning grooves 22 inside, and two corresponding positioning rods 23 are fixedly connected to the outside of the mounting arc block 18. The positioning rods 23 are inserted into the inside of the positioning grooves 22.

[0025] The second collar 14 is provided with a fixing bolt 24, and the plug rod 20 is fixed to the inside of the second collar 14 by the fixing bolt 24.

[0026] One of the brackets 2 has a guide groove inside, and the bottom of the first ring 12 and the second ring 14 are fixedly connected to a guide rod, which is slidably connected in the guide groove.

[0027] In summary, the locking structure of the inspection robot's traveling device, when braking, activates the electric telescopic rod 8 via the control device to extend, pushing the T-shaped slider 7 to slide inside the T-shaped groove 6, then driving the connecting seat 9 to move outside the mounting block 5. Then, the two first connecting blocks 10 drive the two first rotating rods 11 to move, thereby pushing the first collar 12 to move. Then, the two push rods 16 push the second collar 14 to move, and then the mounting arc block 18 pushes the brake disc 19 to move, so that the brake disc 19 and the brake seat 25 fit together, thereby increasing the friction for braking. By disassembling the fixing bolt 24, the fixing of the plug rod 20 is released, thus facilitating the removal of the plug rod 20 and the positioning rod 23 from the inside of the plug groove 21 and the positioning groove 22, and then replacing the brake disc 19 and the mounting arc block 18.
