Description

Technical Field

[0001] This application relates to the field of robot wheel assembly technology, and in particular to an active wheel assembly structure made of aluminum alloy. Background Technology

[0002] Wall-climbing robots are a type of robot that can move autonomously on vertical or inclined surfaces. They are often used to perform tasks such as inspection, cleaning, and maintenance on complex surfaces, thereby replacing high-risk manual labor. The driving capability of the active wheel assembly of a wall-climbing robot directly affects its working efficiency.

[0003] The existing wall-climbing robot active wheel assembly includes an active wheel, a rotating rod fixed in the middle of the active wheel, a drive motor installed at the bottom of the wall-climbing robot, and a coupling for connecting the rotating shaft of the drive motor and the rotating rod. When the worker uses the wall-climbing robot to work, the drive motor drives the rotating rod to rotate, thereby controlling the active wheel. The wall-climbing robot has a fixed magnetic adsorption magnet, which is used to adsorb onto the wall. At this time, the active wheel drives the wall-climbing robot to slide on the wall.

[0004] The aforementioned wall-climbing robot has its active wheel assembly and adsorption magnets separated, resulting in a larger robot size and an inability to bear greater loads, which is an area for improvement. Utility Model Content

[0005] In order to combine the pulley assembly of the wall-climbing robot with the adsorption magnet, thereby reducing the size of the wall-climbing robot and enabling it to bear a larger load, this application provides an active wheel assembly structure made of aluminum alloy.

[0006] This application provides a drive wheel assembly structure made of aluminum alloy, which adopts the following technical solution:

[0007] An active wheel assembly structure made of aluminum alloy includes a connecting seat, a driving member disposed on the side wall of the connecting seat, a rotating rod fixed to the end of the driving member away from the connecting seat, and a pulley fixed to the side wall of the rotating rod. The driving member is used to drive the rotating rod to rotate, and an adsorption member is fixed to the side wall of the driving member, with the adsorption member close to the wall.

[0008] By adopting the above technical solution, when the staff uses the wall-climbing robot, they place the robot on the wall. Under the action of the suction device, the robot is stably fixed to the wall. Then, the staff starts the robot, and the drive unit drives the rotating rod to rotate. The rotating rod drives the pulley to rotate, so that the robot slides on the wall. This setting allows the pulley group of the wall-climbing robot to combine with the suction magnet, thereby reducing the size of the robot and enabling it to bear a larger load.

[0009] Optionally, the driving component includes an outer cover fixed to the side wall of the connecting seat and a driving motor fixed to the inner wall of the outer cover. The rotating shaft of the driving motor is fixed to the end of the rotating rod, and the adsorption component is fixed to the outer wall of the outer cover.

[0010] By adopting the above technical solution, the staff can fix the drive motor to the inner wall of the outer casing, which can reduce the influence of the external environment on the drive motor, thereby improving the stability and life of the motor. The outer casing integrates the drive component and the adsorption component, making the pulley block structure more compact and convenient for the staff to install and maintain the pulley block structure.

[0011] Optionally, the adsorption component includes a mounting bracket fixed to the outer wall of the cover and a magnet fixed to the mounting bracket at one end away from the cover, the magnet being used to adsorb onto the wall.

[0012] By adopting the above technical solution, the fixed frame in this setup is used to support the magnet, which makes it easier for staff to adjust the position and angle of the magnet. This allows the wall-climbing robot to better adapt to walls of different shapes. At the same time, the fixed frame facilitates the installation and maintenance of the magnet by staff, thereby extending the service life of the wall-climbing robot.

[0013] Optionally, the rotating rod includes a shaped rod and a sleeve fixed to the end of the shaped rod away from the drive motor. The inner wall of the sleeve is provided with a locking groove, and the inner wall of the locking groove abuts against the side wall of the shaped rod. Two pulleys are provided, one of which is fixed to the end of the shaped rod near the drive motor, and the other of which is fixed to the end of the sleeve away from the drive motor.

[0014] By adopting the above technical solution, the irregular rod and the locking groove are engaged, which reduces the vibration between the irregular rod and the sleeve and improves the stability of the irregular rod during operation. The dual wheels enhance the obstacle-crossing ability, enabling the wall-climbing robot to move stably in complex terrain and further improving the stability of the wall-climbing robot when climbing.

[0015] Optionally, the magnet includes a magnet sleeve rotatably connected to the outside of the sleeve, and a plurality of magnet blocks fixed to the side of the magnet sleeve away from the rotation axis, and the end of the fixing frame away from the outer cover is fixed to the outer wall of the magnet sleeve.

[0016] By adopting the above technical solution, the inner wall of the magnet sleeve is rotatably connected to the outer side of the sleeve, allowing the magnet sleeve to rotate flexibly on the sleeve, thereby adapting to the adsorption requirements of different angles and positions. At the same time, this setting can reduce the wear caused by external forces on the magnet sleeve during use and improve the service life of the magnet.

[0017] Optionally, the outer ring of the pulley is fixed with a friction element, which abuts against the wall.

[0018] By adopting the above technical solution, the setting of friction components reduces the weight of the pulley block structure and provides sufficient friction for the wall-climbing robot when it moves, making the working process of the wall-climbing robot more stable.

[0019] Optionally, the side wall of the outer cover is provided with a plurality of mounting holes, which are located on the side of the outer cover away from the rotating rod.

[0020] By adopting the above technical solution, the installation holes are designed to facilitate the installation of the pulley blocks by the workers, and the installation holes also help dissipate heat from the drive motor, thus increasing the service life of the drive motor.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. When workers use the wall-climbing robot, they place it on the wall. Under the action of the suction device, the robot is fixed to the wall. Then, the drive unit drives the rotating rod to rotate. As the rotating rod rotates, the pulleys roll on the wall, thus enabling the wall-climbing robot to work on the wall. This design allows the pulley system of the wall-climbing robot to be combined with the suction magnet, thereby reducing the size of the wall-climbing robot and enabling it to bear a larger load.

[0023] 2. When the wall-climbing robot is working, the irregular rod and the locking slot reduce the energy loss of the wall-climbing robot, and the simultaneous operation of the two pulleys reduces the possibility of the wall-climbing robot making mistakes in complex environments.

[0028] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0029] This application discloses an active wheel assembly structure made of aluminum alloy.

[0030] Reference Figure 1 An active wheel assembly structure made of aluminum alloy includes a connecting seat 1, a driving component 2 fixed to one side of the plane of the connecting seat 1, a rotating rod 3 fixed to the driving component 2 on the side away from the connecting seat 1, a pulley 4 fixed to the side wall of the rotating rod 3, and an adsorption component 5 fixed to the outside of the driving component 2. The connecting seat 1 is used to install the pulley 4 assembly structure onto the wall-climbing robot, the side wall of the pulley 4 abuts against the wall, and the adsorption component 5 is used to adsorb onto the wall. The driving component 2 includes an outer cover 21 fixed to one side of the plane of the connecting seat 1 and a drive motor 22 fixed to the inner wall of the outer cover 21 by bolts. The connecting seat 1, outer cover 21, rotating rod 3, and pulley 4 are all made of aluminum alloy, which further reduces the weight of the wall-climbing robot.

[0031] Reference Figure 1 and Figure 2 The adsorption component 5 includes a fixing frame 51 fixed to the side wall of the outer cover 21 by bolts, and a magnet 52 fixed to the fixing frame 51 away from the outer cover 21 by bolts. In this embodiment, the fixing frame 51 is made of aluminum alloy and has a bent structure. The magnet 52 is located near the rotating rod 3. Friction components 7 are installed on the periphery of the pulley 4. In this embodiment, the friction components 7 are preferably made of rubber, thereby improving the friction between the pulley 4 and the wall. The outer cover 21 has a mounting hole 8 on the side near the connecting seat 1. In this embodiment, there are preferably two mounting holes 8. The setting of two mounting holes 8 makes it convenient for workers to install the pulley 4 structure.

[0032] Reference Figure 1 and Figure 3 The rotating rod 3 includes an irregular rod 31 and a sleeve 32 installed on the end of the irregular rod 31 away from the drive motor 22. The end of the irregular rod 31 near the drive motor 22 is fixed to the rotating shaft of the drive motor 22 by a coupling. The inner wall of the sleeve 32 is provided with a locking groove 6, and the end of the irregular rod 31 away from the drive motor 22 abuts against the inner wall of the locking groove 6. The magnet 52 includes a magnet sleeve 521 rotatably connected to the outer wall of the sleeve 32 and a plurality of magnet blocks 522 fixed to the side wall of the magnet sleeve 521. The plurality of magnet blocks 522 are fixed sequentially along the periphery of the magnet sleeve 521 to form a fan-shaped structure close to the wall. The magnet sleeve 521 is preferably made of aluminum alloy.

[0033] The implementation principle of the active wheel assembly structure made of aluminum alloy in this application embodiment is as follows: When the worker uses the wall-climbing robot, the worker places the wall-climbing robot on the wall. At this time, under the adsorption of the magnet 522, the wall-climbing robot works stably on the wall. Then the worker starts the wall-climbing robot, and under the drive of the drive motor 22, the two pulleys 4 rotate, driving the wall-climbing robot to work on the wall. This setting allows the pulley 4 of the wall-climbing robot to combine with the adsorption magnet, thereby reducing the size of the wall-climbing robot and enabling it to bear a larger load.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
