Description

Technical Field

[0001] This utility model relates to the field of mobile wheels for inspection robots, specifically a mobile wheel for inspection robots that is easy to replace. Background Technology

[0002] The inspection robot's wheels, an important component mounted on its bottom, are responsible for providing movement support. Since these wheels are in constant contact with the ground, they are prone to wear or cracking due to material aging, and therefore require regular inspection and timely replacement.

[0003] The casters are typically connected directly to the output shaft of the mobile motor via a flange and secured with four or more bolts. However, due to the relatively small size of the flange and casters, when attempting to precisely align the bolt holes on the casters with the screws on the flange, operators often encounter difficulties because the inspection robot itself and the casters obstruct the screws, making it hard for the screws to pass smoothly through the corresponding holes. This results in low installation efficiency and increased operational difficulty. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an easily replaceable mobile wheel for an inspection robot, which allows for more convenient connection of the mobile wheel to the robot body.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a replaceable inspection robot moving wheel, comprising a moving wheel body installed on one side of the four motor flanges of the robot body, four rods fixedly connected to the side walls of the four motor flanges, four holes penetrating the surface of the four moving wheels, the outer walls of the four rods being slidably connected to the inner walls of the four holes respectively, an elastic alignment component being connected to the side of the moving wheel body near the motor flange, the other end of the elastic alignment component being connected to the motor flange, and the moving wheel body and the motor flange being fastened together by a bolt located inside the elastic alignment component.

[0006] Furthermore, a storage opening is provided on the side of the movable wheel near the motor flange, and the end of the elastic alignment component away from the motor flange is located inside the storage opening.

[0007] Furthermore, the elastic alignment assembly includes a collar, a tube, and a guide assembly. One side of the collar is fixedly connected to the side of the motor flange near the moving wheel. The outer wall of the tube is slidably connected to the inner wall of the collar. The side of the tube away from the motor flange is connected to the guide assembly. The other end of the guide assembly is connected to the receiving port. The outer wall of the tube away from the collar is also slidably connected to the inner wall of the receiving port. A bolt passes through the tube and the collar and is slidably connected to the point where the tube and the collar pass through.

[0008] Furthermore, the guide assembly includes two multi-segment telescopic rods and two thrust springs. One end of each of the two multi-segment telescopic rods and two thrust springs is fixedly connected to the side wall of the insertion tube, and the other end of each of the two multi-segment telescopic rods and two thrust springs is fixedly connected to the inner wall of the receiving port.

[0009] Furthermore, four limiting components are connected to the side of the moving wheel away from the motor flange, which can limit the four plug rods respectively.

[0010] Furthermore, each of the four insertion rods has a through-hole at one end, and the four limiting components are connected to the four through-holes respectively.

[0011] Furthermore, the limiting assembly includes a mounting block, a pull button, a limiting rod, a push block, and a limiting spring. One side of the mounting block is fixedly connected to the side wall of the movable wheel. A spring cavity is formed in the inner wall of the mounting block. One end of the limiting spring is fixedly connected to the inner wall of the spring cavity, and the other end of the limiting spring is fixedly connected to one side of the push block. The outer wall of the push block is slidably connected to the inner wall of the spring cavity. The inner wall of the push block is fixedly connected to the outer wall of the limiting rod. Both ends of the limiting rod extend to the outside of both ends of the mounting block, and the outer wall of one end of the limiting rod is slidably connected to the inner wall of the socket. The outer wall of the other end of the limiting rod is fixedly connected to the pull button.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This type of easily replaceable inspection robot's moving wheels, through the sliding cooperation between the insertion rod and the insertion hole, and the elastic guiding effect of the elastic alignment component, allow the moving wheels to automatically adjust their position, significantly reducing the difficulty of manually aligning the insertion hole and the insertion rod, and achieving rapid preliminary positioning;

[0014] 2. This type of easily replaceable inspection robot's moving wheels only require a single bolt to finally fix the moving wheel body to the motor flange. Compared with the traditional multi-bolt connection method, it greatly reduces the operation steps and tool dependence, and improves replacement efficiency.

[0015] 3. The easily replaceable moving wheels of this inspection robot have a limiting component that automatically locks the insertion port after the insertion rod is fully inserted, forming a double fixation and effectively preventing the moving wheels from loosening or falling off during operation.

[0022] 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.

[0023] Please see Figures 1-5 A replaceable inspection robot moving wheel includes a moving wheel body 2 installed on one side of four motor flanges 6 of the robot body 1. Four plug rods 4 are fixedly connected to the side walls of the four motor flanges 6. Four plug holes 202 are opened through the surface of the four moving wheel bodies 2. The outer walls of the four plug rods 4 are slidably connected to the inner walls of the four plug holes 202 respectively. An elastic alignment component is connected to the side of the moving wheel body 2 near the motor flange 6. The other end of the elastic alignment component is connected to the motor flange 6. The moving wheel body 2 and the motor flange 6 are fastened together by a bolt located inside the elastic alignment component.

[0024] like Figures 1 to 5As shown, the easy-to-replace inspection robot's mobile wheels in this utility model are installed by first lifting one corner of the robot body 1 where the wheels need to be installed. Then, align one end of the elastic alignment component on the mobile wheel body 2 with the other end of the elastic alignment component on the motor flange 6 of the robot body 1. Continue pressing the mobile wheel body 2 towards one side of the robot body 1 until the two parts of the elastic alignment component overlap. After the two parts of the elastic alignment component overlap, the four protruding rods 4 on the motor flange 6 will not be aligned with the insertion holes 202 on the mobile wheel body 2. Therefore, the rods 4 will abut against the surface of the mobile wheel body 2. At this time, due to the initial connection of the elastic alignment component, the mobile wheel body 2 can be rotated using the elastic alignment component as an axis. As the mobile wheel 2 rotates, the rods 4 will... Slide the movable wheel 2 on the hub until the insertion rod 4 aligns with the insertion hole 202. There will be a slight misalignment and jamming. At this point, stop rotating the movable wheel 2. Then, pass a bolt through the movable wheel 2 and the elastic alignment component and align it with the threaded hole on the motor flange 6. Then, rotate the bolt manually or with the help of an external tool. As the bolt is gradually tightened, the bolt head can continue to press the movable wheel 2. At this time, the elastic alignment component is further compressed. At the same time, the four insertion rods 4 are inserted into the four insertion holes 202 respectively. After reaching the other side of the insertion hole 202, the bolt is fully tightened, and the elastic alignment component can no longer be compressed. At this point, the insertion rods 4 stop. Thus, the movable wheel 2 and the motor flange 6 can be stably and quickly installed and fixed by one bolt and four insertion rods 4.

[0025] Please refer to the following: Figures 1-5 The movable wheel 2 has a storage opening 201 on the side near the motor flange 6, and the end of the elastic alignment component away from the motor flange 6 is located in the storage opening 201.

[0026] More specifically, by setting up the storage opening 201, the elastic alignment component can be stored, reducing the space occupied by it.

[0027] Please refer to the following: Figures 1-5 The elastic alignment assembly includes a collar 7, a tube 8, and a guide assembly. One side of the collar 7 is fixedly connected to the side of the motor flange 6 near the moving wheel 2. The outer wall of the tube 8 is slidably connected to the inner wall of the collar 7. The side of the tube 8 away from the motor flange 6 is connected to the guide assembly. The other end of the guide assembly is connected to the receiving port 201. The outer wall of the end of the tube 8 away from the collar 7 is also slidably connected to the inner wall of the receiving port 201. A bolt passes through the tube 8 and the collar 7 and is slidably connected to the point where the tube 8 and the collar 7 pass through.

[0028] The guide assembly includes two multi-segment telescopic rods 9 and two thrust springs 10. One end of each of the two multi-segment telescopic rods 9 and the two thrust springs 10 is fixedly connected to the side wall of the insertion tube 8, and the other end of each of the two multi-segment telescopic rods 9 and the two thrust springs 10 is fixedly connected to the inner wall of the receiving port 201.

[0029] More specifically, when installing the movable wheel 2 with the motor flange 6, simply align the insertion tube 8 on the movable wheel 2 with the collar 7 of the motor flange 6. Because of the action of the two multi-segment telescopic rods 9 and the two thrust springs 10, the distance between the movable wheel 2 and the motor flange 6 is relatively far at this time, and will not completely obstruct the line of sight, thereby improving the alignment speed.

[0030] After aligning the insertion tube 8 with the collar 7, slightly press the movable wheel 2 towards the robot body 1 so that the hub of the movable wheel 2 abuts against the four insertion rods 4 on the motor flange 6. At this point, the two multi-stage telescopic rods 9 and the two thrust springs 10 can no longer be compressed. Then rotate the movable wheel 2 to any side. When the insertion hole 202 on the movable wheel 2 aligns with the insertion rod 4, there will be a misalignment between the insertion rod 4 and the insertion hole 202. At this point, pass a bolt through the movable wheel 2 and tighten the bolt's thread end. Insert the bolt into the threaded hole of the motor flange 6, and then manually or with the help of an external tool turn the bolt. Turning the bolt will continue to press the moving wheel 2 to continue compressing the two multi-stage telescopic rods 9 and the two thrust springs 10 until the two multi-stage telescopic rods 9, the two thrust springs 10 and the end of the insertion tube 8 away from the collar 7 are completely retracted into the storage port 201 and can no longer be compressed. Then, simply release the force that originally lifted the robot body 1, and the robot body 1 will fall down by itself due to gravity and stand stably on the ground.

[0031] Please refer to the following: Figures 1-5 The side of the movable wheel 2 away from the motor flange 6 is connected to four limiting components that can limit the four plug rods 4 respectively.

[0032] Each of the four insertion rods 4 has a socket 401 through one end of the insertion hole 202, and the four limiting components are respectively connected to the four sockets 401.

[0033] The limiting assembly includes a mounting block 3, a pull button 5, a limiting rod 11, a push block 12, and a limiting spring 13. One side of the mounting block 3 is fixedly connected to the side wall of the movable wheel 2. A spring cavity 301 is formed in the inner wall of the mounting block 3. One end of the limiting spring 13 is fixedly connected to the inner wall of the spring cavity 301, and the other end of the limiting spring 13 is fixedly connected to one side of the push block 12. The outer wall of the push block 12 is slidably connected to the inner wall of the spring cavity 301. The inner wall of the push block 12 is fixedly connected to the outer wall of the limiting rod 11. Both ends of the limiting rod 11 extend to the outside of both ends of the mounting block 3, and the outer wall of one end of the limiting rod 11 is slidably connected to the inner wall of the socket 401. The outer wall of the other end of the limiting rod 11 is fixedly connected to the pull button 5.

[0034] More specifically, during installation, after the bolts securely connect the movable wheel 2 to the motor flange 6, the four insertion rods 4 will fully penetrate the movable wheel 2 to the side away from the motor flange 6. After passing through the insertion hole 202, the insertion rods 4 will abut against the inclined surface of the limiting rod 11. As the movable wheel 2 gets closer to the motor flange 6, the insertion rods 4 will extend further, and the limiting rod 11 will descend further, compressing the limiting spring 13. When the insertion rods 4 move to the moving position, the limiting rod 11 aligns with the insertion port 401. At this point, under the action of the limiting spring 13, the limiting rod 11 can be inserted into the insertion port 401, thus allowing for four additional fixings in conjunction with the bolts, further increasing the connection between the movable wheel 2 and the motor flange 6.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
