Technical Field

[0001] This utility model relates to the field of tire changing technology for mining trucks, specifically to a mechanical arm for changing tires on a mining truck based on a loader platform. Background Technology

[0002] In mining operations, mining trucks serve as crucial transportation tools, carrying large quantities of ore, soil, and other mineral resources. These trucks typically possess strong traction and high load capacity, enabling them to adapt to the complex and harsh working environments of mines, such as rugged roads, high temperatures, dust, and intense workloads. Consequently, mining truck tires frequently face problems such as damage, wear, and leaks, especially after prolonged periods of high-load operation, increasing the risk of tire failure and necessitating regular tire replacement.

[0003] However, changing tires on mining trucks is extremely challenging. First, due to the large size and weight of the tires, changing them requires significant physical strength and skill. Traditional manual tire changing methods are not only time-consuming and inefficient, but also prone to accidents or injuries due to improper operation. Second, mining trucks are typically parked on uneven ground or in hazardous areas, presenting numerous safety risks for manual operation. Furthermore, changing mining truck tires usually requires multiple workers to work together, increasing labor costs, and working in harsh environments can easily lead to worker fatigue and reduce work efficiency.

[0004] To address these issues, those skilled in the art have proposed a mining truck tire-changing robotic arm based on a loader platform to solve the problems mentioned in the background section. Utility Model Content

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0023] Example:

[0024] Please see Figures 1-3 In this embodiment, a mining truck tire changing robotic arm based on a loader platform is provided, including a main support 3. A movable support plate 4 is installed on one side of the main support 3. The movable support plate 4 is installed on a fixed support plate 5. The fixed support plate 5 is connected to the loader and is installed at the front end of the loader's working mechanism. The robotic arm can be raised, lowered, lifted or lowered using the loader's working mechanism. Moreover, the hydraulic and electrical circuits in the robotic arm are connected to the power output of the loader platform.

[0025] Two symmetrical clamps 2 are provided on the side of the main support 3 away from the movable support plate 4. A claw 1 is installed on the side of the end of each clamp 2 that is close to each other. The two claws 1 interact with each other to clamp the tire. In the clamped state, they can drive the tire to rotate 360 ​​degrees, which can provide convenience when installing the tire.

[0026] The clamping device 2 includes multiple connecting rods and clamping cylinders. The connecting rods and clamping cylinders interact to achieve mechanical transmission of multiple joints, which in turn can drive the gripper 1 to perform translation and clamping of the tire. The connection method between the connecting rods and clamping cylinders adopts existing technology, which is conventional technology for those skilled in the art. Therefore, its specific structure and connection and installation method will not be described in detail here.

[0027] A video probe and a gripping status sensor 6 are installed on the top of the fixed support plate 5 to accurately determine the working status of the robotic arm.

[0028] The video probe is mainly used to observe the situation at the tire clamping site. The tire clamping sensor is connected to the clamping cylinder. By detecting whether the working pressure of the clamping cylinder is stable, the tire clamping status is determined, which makes the operation of the robotic arm more reliable and safe.

[0029] When installing tires on mining trucks, the tires need to be able to rotate left and right or move and swing back and forth in order to align with the bolt holes. Therefore, a hydraulic motor is installed between the movable support plate 4 and the main support 3. The hydraulic motor drives the main support 3 to rotate the tire 360 ​​degrees radially. At the same time, a hydraulic cylinder is installed between the movable support plate 4 and the fixed support plate 5. The hydraulic cylinder can drive the movable support plate 4 to move the tire left and right, and the gripper 1 can swing the tire back and forth, providing all-round convenience for tire changing.

[0030] This utility model utilizes a hydraulic multi-joint mechanical transmission to achieve 360-degree clamping and installation of large tires, with the hydraulic and electrical circuits connecting to the power output of the loader platform. Simultaneously, it uses visual information transmission to detect and resolve blind spots during installation and achieve automatic correction of actions, avoiding blind spots in human vision and reducing the occurrence of accidents.

[0031] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
