[0002] As a core material conveying equipment in industries such as thermal power and steel, the operating status of coal conveyor belts directly affects the continuity of production. With its all-round monitoring advantages, the rail-mounted inspection robot has become the mainstream inspection tool. This type of robot is suspended above the conveyor belt by a rail assembly, and the connection structure is the core to achieve a stable connection between the robot and the rail body.

[0003] However, existing connection structures have low assembly efficiency, mostly using bolted hard connections. The docking of the robot body with the rail and functional modules requires sequential tightening and special tools. At the same time, the stability after connection is poor. The high-frequency vibration of the coal conveyor belt during operation can easily cause the bolts to loosen, which can lead to an increase in connection gaps and affect the inspection accuracy. In addition, the maintenance convenience is insufficient. Disassembly is difficult after the bolts are corroded or stripped. Fault repair requires stopping the machine for disassembly, which is time-consuming and labor-intensive. Therefore, there is an urgent need for a fast and efficient connection structure for coal conveyor belt inspection robots to solve the above problems. Utility Model Content

[0018] 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.

[0019] Please see Figures 1-7 This utility model provides a fast and efficient connection structure for a coal conveyor belt inspection robot, including the main body 1 of the inspection robot, and also including: A connecting component is provided on the top surface of the inspection robot body 1 and is used to quickly connect the inspection robot body 1 to the hanging rail. A contact component is provided on the top surface of the connecting component to improve the stability of the connection between the main body 1 of the inspection robot and the hanging rail; The connecting components allow the sliding parts to move under the weight of the inspection robot body 1. This movement causes the two sets of tightening parts on the left and right to move closer to the center of the rail, facilitating a quick connection with the rail. Conversely, when the inspection robot body 1 is lifted from the bottom after use, it can be quickly detached from the rail. Simultaneously, the contact components allow the first and second contact parts to come into contact with the inner wall of the rail under the influence of gravity. The contact points generated by the two forces of gravity improve the stability of the inspection robot body 1 during movement.

[0020] Furthermore, the connecting assembly includes a sliding frame 201, which is disposed on the top surface of the inspection robot body 1. A connecting plate 203 is slidably connected to the inner wall of the sliding frame 201. Limiting frames 204 are fixedly connected to both sides of the connecting plate 203. Two tightening frames 205 are provided on the inner wall of the limiting frames 204. Two rotating columns 207 are rotatably connected to the inner walls of the two limiting frames 204. Multiple spur gears 208 are fixedly connected to the surface of the rotating columns 207. Multiple first gears 208 are provided on both sides of the sliding frame 201. The bottom surface of the first toothed groove 202 and the tightening frame 205 has multiple second toothed grooves 206. Both the first toothed groove 202 and the second toothed grooves 206 are meshed with the spur gear 208. Through the set connecting components, the sliding frame 201 is pulled to move under the gravity of the inspection robot body 1. The movement of the sliding frame 201 drives the rotating column 207 to rotate through the set spur gear 208. When the rotating column 207 rotates, it drives the tightening frame 205 to move through the spur gear 208. The multiple tightening frames 205 are divided into left and right groups. When the sliding frame 201 descends under the gravity of the inspection robot body 1, the two rotating columns 207 and multiple spur gears 208 work together to drive the two sets of tightening frames 205 on the left and right to move closer to the center of the sliding frame 201, thus facilitating a quick connection with the hanging rail. Conversely, when the inspection robot body 1 is lifted from bottom to top after use, the sliding frame 201 moves upward, causing the two sets of tightening frames 205 to open, thus quickly detaching the inspection robot body 1 from the hanging rail. Through the cooperation of multiple first tooth grooves 202, second tooth grooves 206 and spur gears 208, when the sliding frame 201 moves, the first tooth grooves 202 drive the multiple spur gears 208 located in the middle to rotate. The multiple spur gears 208 located in the middle drive the rotating columns 207 to rotate. The rotation of the rotating columns 207 drives the two spur gears 208 at both ends of the rotating columns 207 to rotate. The rotation of the two spur gears 208 at both ends of the rotating columns 207 drives the tightening frames 205 to move through the second tooth grooves 206.

[0021] Furthermore, the contact assembly includes two mounting boxes 301, which are fixedly connected to the top surfaces of two tensioning brackets 205. A semi-circular block 302 is provided on the inner wall of each mounting box 301, and a connecting post 303 is fixedly connected to the inner wall of the semi-circular block 302. A first contact wheel 304 is rotatably connected to the surface of the connecting post 303. Multiple limiting grooves 305 are formed on the inner wall of the mounting box 301, and the semi-circular block 302 is rotatably connected to the inner walls of two of the limiting grooves 305. A mounting bracket 309 is fixedly connected to the surface of the connecting post 303. A movable column 310 is rotatably connected to the inner wall of the mounting frame 309. A second contact wheel 311 is fixedly connected to the surface of the movable column 310. Multiple small motors 312 are provided on the top surface of the mounting frame 309. The small motors 312 are fixedly connected to the top surface of the mounting frame 309. The surface of the movable column 310 is fixedly connected to the output end of the small motors 312. Through the provided contact components, the two mounting boxes 301 fix the two sets of tightening frames 205 together. Through the provided multiple first contact wheels 304, the inspection robot body... When connected to the rail, multiple first contact wheels 304 are in close contact with the rail due to the gravity of the inspection robot body 1, thus ensuring the stability of the inspection robot body 1 during travel. Secondly, multiple limiting grooves 305 are provided to limit the semicircular block 302, allowing the first contact wheels 304 to drive the semicircular block 302 to rotate under the constraint of the limiting grooves 305 according to the curvature of the rail during travel, thereby improving the flexibility of the inspection robot body 1 when turning on the rail. Through the cooperation of the mounting bracket 309 and the second contact wheel 311, when the sliding frame 201 is pulled down by the gravity of the inspection robot body 1 and the two mounting boxes 301 move towards the center, the second contact wheel 311 contacts and abuts against the inner wall of the rail, thus providing a second contact point in addition to the first contact wheel 304, thereby improving the stability of the inspection robot body 1 when moving. At the same time, the small motor 312 provides power for the rotation of the second contact wheel 311, thereby driving the inspection robot body 1 to move.

[0022] Furthermore, the inner wall of the mounting box 301 is provided with multiple first fixing grooves 306, and the side wall of the semicircular block 302 is provided with two second limiting grooves 307. The first fixing grooves 306 and the second limiting grooves 307 are fixedly connected with the same compression spring 308. With the multiple compression springs 308, each side wall of the semicircular block 302 has two compression springs 308. The compression of the two compression springs 308 keeps the side wall of the semicircular block 302 parallel to the inner wall of the mounting box 301, so that the semicircular block 302 can be reset under the push of the compression springs 308 after turning with the rail. The first fixing grooves 306 and the second limiting grooves 307 work together to limit the compression springs 308.

[0023] Furthermore, a sliding hole 210 is provided on the bottom surface of the left tightening frame 205, and an elongated hole 215 is provided on the side wall of the right tightening frame 205. The left tightening frame 205 is slidably connected to the inner wall of the right elongated hole 215, and the right tightening frame 205 is slidably connected to the inner wall of the left sliding hole 210. Both tightening frames 205 are slidably connected to the inner wall of the limiting frame 204. Two rotating holes 209 are provided on the inner wall of the limiting frame 204, and the surface of the rotating column 207 rotates with the inner wall of the rotating hole 209. The moving connection uses the sliding hole 210 and the elongated hole 215 to cooperate with each other, which makes it easy to avoid interference between the left and right sets of tightening frames 205 when they move, and at the same time, it is easy to synchronously limit the left and right sets of tightening frames 205, thereby improving the stability of the tightening frame 205 when it moves. The rotating hole 209 makes it easy to limit the rotating column 207, and the limiting frame 204 makes it easy to limit the tightening frame 205, thereby allowing the tightening frame 205 and the limiting frame 204 to move in parallel.

[0024] A mounting plate 211 is fixedly connected to the top surface of the inspection robot body 1. Multiple connection holes 212 are provided on the bottom surface of the mounting plate 211. The top surface of the mounting plate 211 is fixedly connected to the bottom surface of the sliding frame 201. Two limiting holes 213 are provided on the bottom surface of the connecting plate 203. Limiting posts 214 are slidably connected to the inner walls of the limiting holes 213. The upper ends of the two limiting posts 214 are fixedly connected to the inner walls of the sliding frame 201, and the lower ends of the two limiting posts 214 are fixedly connected to the top surface of the mounting plate 211. The mounting plate 211 and the connection holes 212 work together to facilitate the connection between the inspection robot body 1 and the sliding frame 201. The limiting holes 213 work together to limit the movement between the connecting plate 203 and the sliding frame 201, thereby allowing the sliding frame 201 to move horizontally up and down, thus improving the stability of the connection between the sliding frame 201 and the connecting plate 203.

[0025] Working principle: During use, the connecting components allow the sliding frame 201 to move under the weight of the inspection robot body 1. The movement of the sliding frame 201 drives the rotating column 207 to rotate via the spur gear 208. When the rotating column 207 rotates, it drives the tightening frame 205 to move via the spur gear 208. The tightening frames 205 are divided into two groups, left and right. When the sliding frame 201 descends under the weight of the inspection robot body 1, the two rotating columns 207 and the multiple spur gears 208 work together to move both groups of tightening frames 205 toward the center of the sliding frame 201, thus facilitating quick connection with the hanging rail. Conversely, when the inspection robot body 1 is lifted from bottom to top after use, the sliding frame 201 moves upward, causing the two groups of tightening frames 205 to open, thus quickly detaching the inspection robot body 1 from the hanging rail.

[0026] The contact components allow the two mounting boxes 301 to securely connect the two sets of tensioning frames 205. Multiple first contact wheels 304 ensure close contact between the inspection robot body 1 and the rail under the influence of the robot body 1's gravity when the robot body 1 is connected, thus guaranteeing the stability of the robot body 1 during movement. Furthermore, multiple limiting grooves 305 facilitate the limiting of the semi-circular block 302, allowing the first contact wheels 304 to move freely during movement. According to the curvature of the rail, the semicircular block 302 is driven to rotate under the constraint of the limiting groove 305, thereby improving the flexibility of the inspection robot body 1 when turning on the rail. At the same time, the mounting bracket 309 and the second contact wheel 311 work together to make the sliding bracket 201 pull down the two mounting boxes 301 towards the center under the gravity of the inspection robot body 1, so that the second contact wheel 311 contacts and abuts against the inner wall of the rail, thereby providing a second contact point in addition to the first contact wheel 304, thereby improving the stability of the inspection robot body 1 when moving.
