Description

Technical Field

[0001] The utility model belongs to the field of wheel devices, and particularly relates to a mountain wheel used on an inspection robot. Background Art

[0002] The mountain wheel on the inspection robot is a special wheel designed for the inspection robot to walk in complex mountain environments. At present, there are some disadvantages in the mountain wheels on the inspection robot. First of all, the lack of an anti-slip structure will lead to insufficient grip when walking on complex terrains such as mountains, and it is easy to slip, especially on wet, muddy or sloping ground, which greatly affects the walking stability and safety of the inspection robot. This disadvantage is mainly due to the fact that the requirements of complex terrains are not fully considered during the design, or the anti-slip structure is omitted in order to reduce costs, reduce weight, etc. For this disadvantage, the conventional countermeasure may be to reduce the walking speed of the robot, but this will reduce the inspection efficiency, prolong the inspection time, and in some emergency situations, it may not be able to reach the designated position in time for inspection. Another method is to choose a relatively flat route to walk, but this will limit the activity range of the inspection robot, and some important areas may not be inspected, affecting the comprehensiveness and accuracy of the inspection. At the same time, this method may also increase the walking distance of the robot, consume more energy, and shorten the battery life of the robot. Therefore, a new structure needs to be proposed to solve the above technical problems. Summary of the Utility Model

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] Please refer toFigures 1 to 3 , the present utility model provides a technical solution: a mountain wheel used on an inspection robot, including: a first wheel body assembly, a second wheel body assembly, and a connecting rod 240. The first wheel body assembly and the second wheel body assembly are connected by the connecting rod 240. The diameter of the first wheel body assembly matches the diameter of the second wheel body assembly. The first wheel body assembly includes: a hub 100, a wheel spoke 130, a wheel axle 120, and a tire 110. A wheel axle 120 is installed at the center position inside the hub 100 through the wheel spoke 130. An installation hole one 121 is installed through the center of the surface of the wheel axle 120. A tire 110 is installed on the outer surface of the hub 100. An anti-slip pattern 111 is provided on the outer surface of the tire 110. The connecting rod 240 is installed inside the installation hole one 121 of the wheel axle 120. The outer surface of the end of the connecting rod 240 away from the first wheel body assembly is installed with the second wheel body assembly. The second wheel body assembly includes: a first wheel plate 200, a second wheel plate 210, an airbag wheel 220, a fixing bolt 221, and an installation hole two 230. A plurality of airbag wheels 220 are installed between the first wheel plate 200 and the second wheel plate 210 through the fixing bolt 221. The installation hole two 230 penetrates between the first wheel plate 200 and the second wheel plate 210.

[0020] Please refer to Figures 1 to 3 , as the first embodiment of the present utility model: a plurality of wheel spokes 130 are evenly installed on the inner wall of the hub 100. One end of the wheel spoke 130 away from the hub 100 is connected to the outer surface of the wheel axle 120. A tire 110 is clamped on the outer surface of the hub 100. A strip-shaped anti-slip pattern 111 is provided at the center position of the outer surface of the tire 110. The connecting rod 240 is installed in the installation hole one 121 at the center position of the wheel axle 120. The outer surface of the end of the connecting rod 240 away from the wheel axle 120 is installed inside the installation hole two 230;

[0021] The structures of the installation hole one 121 and the installation hole two 230 match. The rear surface of the first wheel body assembly and the front surface of the second wheel body assembly are connected by mutual abutment through the connecting rod 240. The front surface of the second wheel plate 210 abuts against the front surface of the hub 100;

[0022] When in use, the user can install a wheel body formed by connecting the first wheel body component and the second wheel body component through a connecting rod 240 at the wheel of the inspection robot (as for how to install or drive it, the user can choose according to the actual situation and will not be elaborated here). After the wheel body is installed, at this time, the second wheel body component faces inward. Since the first wheel body component and the second wheel body component are connected by the connecting rod 240, a more stable structure is formed. In complex mountain terrains, the two wheel bodies can better share the weight of the robot, improving the overall stability. Especially on rough roads, it can reduce the shaking and tilting of the robot, ensuring the smooth progress of the inspection work. Moreover, the anti-slip patterns 111 on the outer surface of the tire 110 of the first wheel body component, in combination with the second wheel body component, can increase the friction between the tire 110 and the ground, preventing slipping when walking on mountains. Especially in wet, muddy or sloped terrains, the anti-slip patterns 111 can provide better traction, enabling the inspection robot to smoothly pass through various complex terrain conditions.

[0023] Please refer to Figures 1 to 3 , as the second embodiment of the present utility model: The central axes of the mounting holes two 230 on the surfaces of the first wheel plate 200 and the second wheel plate 210 are collinearly aligned with the central axis of the mounting hole one 121 of the wheel axle 120. The structures of the first wheel plate 200 and the second wheel plate 210 are matched. Airbag wheels 220 are installed at an angle of 25 degrees between the outer edges of the first wheel plate 200 and the second wheel plate 210 respectively through fixing bolts 221;

[0024] The outer surface of the airbag wheel 220 abuts against the ground, and the outer surface of the airbag wheel 220 is flush with the outer surface of the tire 110. The structures of multiple airbag wheels 220 are the same;

[0025] A plurality of fixing rings are evenly installed on the front surface of the first wheel plate 200 in an annular structure. A pin 250 is fixed inside the fixing ring through a screw. The pin 250 is installed on the front surface of the first wheel plate 200 in an annular structure through a fixing ring 251. One end of the pin 250 away from the fixing ring 251 abuts against the ground;

[0026] When in use, the second wheel body assembly is installed on the inner surface of the first wheel body assembly. When the first wheel body assembly rotates, the pin 250 on the outer surface of the second wheel body assembly will also rotate accordingly, thus achieving a certain anchoring effect, preventing the second wheel body assembly from slipping on the mountain road surface, and then preventing the entire wheel body from slipping. At the same time, when the second wheel body assembly rotates, the combination of multiple pneumatic wheels 220 on its outer surface increases the contact area between the second wheel body assembly and the ground. Combined with the anti-slip pattern 111 of the first wheel body assembly, in complex terrains such as mountains, the larger contact area can provide better grip, preventing the robot from slipping during walking. Especially on wet or sloping terrains, this increased grip is particularly important, ensuring that the robot can perform inspection work safely and stably. Since the hub 100 and tire 110 structures of the first wheel body assembly are combined with the pneumatic wheels 220 of the second wheel body assembly, a combination with both stability and flexibility is formed. On relatively flat terrains, the first wheel body assembly can provide the main support and traction, while in complex terrains, the pneumatic wheels 220 of the second wheel body assembly play their advantages, jointly providing good walking performance for the robot.

[0027] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
