Description

Technical Field

[0001] This application relates to the field of wall-climbing robot chassis technology, and in particular to a chassis structure for a wall-climbing robot used for testing. Background Technology

[0002] A wall-climbing robot for inspection is an intelligent robot that can move and perform inspection tasks on vertical or inclined surfaces. It is widely used for wall inspection of chemical storage tanks, ships, large industrial equipment, etc., and for inspecting the surface of ship hulls during ship manufacturing and maintenance. The adsorption capacity of the robot's chassis directly affects the efficiency of its inspection work.

[0003] The existing wall-climbing robot chassis includes a frame, adsorption platforms installed on both sides of the frame, a rotating component installed on the adsorption platform, and a magnet component fixed on the rotating component. When the staff uses the wall-climbing robot to carry out inspection work, the staff places the wall-climbing robot on the working wall, and then starts the wall-climbing robot. Under the adsorption of the magnet component, the wall-climbing robot slides stably on the wall. The rotating component allows the staff to change the adsorption angle of the magnet component.

[0004] The aforementioned wall-climbing robot only adheres to the wall surface through magnetic attraction. When working on non-magnetic wall surfaces, the robot is prone to falling, indicating a need for improvement. Utility Model Content

[0005] In order to increase the way the wall-climbing robot can adhere to the wall surface, so that the wall-climbing robot can maintain stable operation when working on non-magnetic material walls, this application provides a chassis structure for a wall-climbing robot for testing.

[0006] This application provides a chassis structure for a wall-climbing robot used for testing, which adopts the following technical solution:

[0007] A chassis structure for a wall-climbing robot for detection includes a base frame, power components disposed on both sides of the base frame, and a drive component disposed on the side wall of the base frame. The power components are capable of adsorbing magnetic wall surfaces, and the drive component is used to drive the power components to move. The side wall of the base frame is also provided with a turbine fan, which is used to adsorb non-magnetic wall surfaces.

[0008] By adopting the above technical solution, when staff use the wall-climbing robot for inspection work, they place the wall-climbing robot on a non-magnetic wall surface. At this time, the turbine fan rotates to provide the wall-climbing robot with an adsorption force, and the drive component drives the power component to slide on the non-magnetic wall surface. This setting increases the way the wall-climbing robot can adhere to the wall surface, so that the wall-climbing robot can maintain stable operation when working on non-magnetic material walls.

[0009] Optionally, a plurality of turbofans are provided, and the plurality of turbofans are arranged in pairs facing each other.

[0010] By adopting the above technical solution, this setting makes the suction force provided by the turbofan stronger and keeps the wall-climbing robot stable during sliding, thus increasing the stability of the wall-climbing robot during operation.

[0011] Optionally, the power assembly includes a power shaft, a power wheel fixed to the end of the power shaft, a support frame fixed to the side wall of the power wheel, and a driven wheel fixed to the end of the support frame away from the power wheel. The end of the power shaft away from the power wheel is connected to the driving member, and the driving member drives the power shaft to rotate.

[0012] By adopting the above technical solution, the power shaft transmits the torque of the driving component to the power wheel, thereby driving the power wheel to rotate. The support frame fixes the relative position of the power wheel and the driven wheel, making the sliding process of the wall-climbing robot more stable.

[0013] Optionally, the power assembly further includes a magnetic track installed on the outside of the drive wheel, the magnetic track being wound around the outside of the driven wheel, and the magnetic track being able to attract magnetic surfaces.

[0014] By adopting the above technical solution, the magnetic track increases the contact area between the wall-climbing robot and the magnetic wall surface, thereby improving the stability of the wall-climbing robot when sliding on the wall surface. The magnetic setting enhances the adhesion of the wall-climbing robot, further reducing the possibility of the wall-climbing robot falling off the magnetic wall surface.

[0015] Optionally, the outer rings of the drive wheel and the driven wheel are each fixed with a number of locking strips at intervals, and the inner ring of the magnetic track is provided with a number of locking slots at intervals. The locking strips and the locking slots are arranged opposite to each other, and the number of locking slots and the locking strips are evenly spaced apart.

[0016] By adopting the above technical solution, the setting of the clip and slot reduces the possibility of the magnetic track slipping on the outer wall of the drive wheel and driven wheel respectively, thereby improving the efficiency of power transmission. The meshing of the clip and slot also increases the friction of the magnetic track, thereby improving the traction of the wall-climbing robot.

[0017] Optionally, an auxiliary wheel is fixed to the side of the drive wheel away from the drive rod, and a distance sensor is installed on the side wall of the auxiliary wheel.

[0018] By adopting the above technical solution, the auxiliary wheels provide support for the wall-climbing robot, and the distance sensor facilitates the wall-climbing robot to detect the distance between itself and the wall, which helps the wall-climbing robot adjust its position to avoid collisions. This setting improves the wall-climbing robot's environmental adaptability and enables it to maintain stable operation in complex environments.

[0019] Optionally, a plurality of detection modules are fixed to the side wall of the base frame, and the plurality of detection modules are used to detect the wall surface condition.

[0020] By adopting the above technical solution, the detection module setting increases the detection range of the wall-climbing robot, and the modular setting makes it easy for staff to disassemble and assemble the detection module. This setting increases the working range of the wall-climbing robot, thereby improving the detection efficiency of the wall-climbing robot.

[0021] Optionally, each of the two support frames has a support seat fixed to its side wall, and the support seat is fixed near both ends of the support frame.

[0022] By adopting the above technical solution, the support base makes it easier for workers to add more components of the wall-climbing robot to the chassis structure. At the same time, the support base increases the rigidity of the support frame, thereby reducing the possibility of deformation of the support frame.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] A chassis structure for a wall-climbing robot for detection includes a base frame, power components disposed on both sides of the base frame, and drive components disposed on the side walls of the base frame. The power components are capable of adsorbing magnetic wall surfaces, and the drive components are used to drive the power components to move. The side walls of the base frame are also provided with turbine fans for adsorbing non-magnetic wall surfaces.

[0025] 1. When workers use the wall-climbing robot for inspection, they place the robot on a non-magnetic wall and start it. The drive unit then activates the power unit, causing the robot to slide on the non-magnetic wall. Under the suction of the turbine fan, the robot adheres to the side wall of the non-magnetic wall. When workers use the wall-climbing robot on a magnetic wall, the turbine fan and power unit work together to provide suction force. This design increases the ways in which the wall-climbing robot can adhere to the wall, ensuring stable operation when working on non-magnetic wall surfaces.

[0026] 2. When the wall-climbing robot is performing inspection work on the magnetic wall, the distance sensor detects the distance between the wall-climbing robot and the adjacent magnetic wall, and the detection module detects the state of the magnetic wall. This setting makes the working process of the wall-climbing robot more stable and increases the working range of the wall-climbing robot. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] This application discloses a chassis structure for a wall-climbing robot used for testing.

[0033] Reference Figure 1 A chassis structure for a wall-climbing robot for detection includes a base frame 1, power components 2 mounted on both sides of the base frame 1, drive components 3 disposed on the side walls of the base frame 1, and a plurality of turbofans 4 fixed on the base frame 1. The drive components 3 are located between two power components 2 and are used to drive the power components 2. In this embodiment, the drive components 3 are preferably drive motors and are mechanically connected to the power components 2. The turbofans 4 are preferably four in number and are arranged in pairs on the front and rear sides of the base frame 1. The power components 2 are capable of providing magnetic adsorption force.

[0034] Reference Figure 1 and Figure 3 The power assembly 2 includes a power shaft 21, a power wheel 22 fixed to the end of the power shaft 21 away from the base frame 1, a support frame 23 fixed to the side of the power wheel 22 away from the power shaft 21 by bolts, a driven wheel 24 fixed to the support frame 23 away from the power wheel 22 by bolts, and a magnetic track 25 installed on the outside of the power wheel 22. The end of the power shaft 21 near the drive member 3 meshes with the rotating shaft of the drive member 3 through a gear, and the end of the power shaft 21 away from the drive member 3 is interference-fitted with the inner wall of the power wheel 22. The magnetic track 25 is wound around the outside of the power wheel 22 and the driven wheel 24 respectively. An auxiliary wheel 7 is fixed to the end of the power wheel 22 away from the power shaft 21. The diameter of the auxiliary wheel 7 is larger than the diameter of the power wheel 22, and the lower side of the auxiliary wheel 7 is flush with the lower side of the magnetic track 25.

[0035] Reference Figure 1 and Figure 2 Several locking strips 5 are fixed on the outer side of the drive wheel 22 and the outer side of the driven wheel 24. The locking strips 5 are evenly spaced along the outer side of the drive wheel 22 and the driven wheel 24. Several slots 6 are opened on the inner wall of the magnetic track 25. The slots 6 are evenly spaced along the inner wall of the magnetic track 25. The locking strips 5 and the slots 6 are arranged opposite each other. Several friction strips are evenly welded to the outer side of the magnetic track 25 and the auxiliary wheel 7. The side wall of the friction strip abuts against the wall surface.

[0036] Reference Figure 1 and Figure 3 A distance sensor 8 is installed at the end of the auxiliary wheel 7 away from the power shaft 21. The distance sensor 8 is located at the axial center of the auxiliary wheel 7. An extension plate is fixed to the side wall of the base frame 1. The extension plate is located above the base plate. A detection module 9 is fixed to the side wall of the extension plate. The detection module 9 can carry various types of detection equipment. Support seats 10 are fixed to both sides of the support frame 23. The support seats 10 are fixed to the side walls of the two support frames 23 by bolts. The support seats 10 are located above the base frame 1. The setting of the support seats 10 makes it convenient for workers to install more components of the wall-climbing robot on the support seats 10.

[0037] The implementation principle of the chassis structure of a wall-climbing robot for testing in this application embodiment is as follows: When the worker uses the wall-climbing robot, the worker places the wall-climbing robot on a magnetic wall surface. At this time, the magnetic track 25 and the turbine fan 4 jointly provide the adsorption force. When the magnetic track 25 cannot work normally, the turbine fan 4 provides the necessary adsorption force for the wall-climbing robot. When the wall-climbing robot works on a non-magnetic wall surface, the turbine fan 4 provides the adsorption force for the wall-climbing robot. Subsequently, the drive component 3 drives the power shaft 21 to rotate, and the power shaft 21 drives the power wheel 22 to rotate. The magnetic track 25 moves on the non-magnetic wall surface, realizing the wall-climbing robot's work on the non-magnetic wall surface. This setting increases the way the wall-climbing robot adsorbs onto the wall surface, so that when the wall-climbing robot works on a non-magnetic material wall surface, the wall-climbing robot maintains stable operation.

[0038] 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.
