Description

Technical Field

[0001] This utility model belongs to the field of rubber ball maintenance technology, and relates to a convenient maintenance structure for rubber balls. Background Technology

[0002] Existing rubber ball positioning systems have several drawbacks in positioning accuracy, including insufficient accuracy, high maintenance costs, and limited lifespan. These drawbacks stem from the physical properties of rubber materials, such as elastic deformation, wear, and aging, as well as the dynamic loads and environmental factors experienced by the ball during use. Under prolonged stress and environmental erosion, rubber balls are prone to deformation and wear, leading to decreased positioning accuracy. Furthermore, the inhomogeneity of rubber materials makes it difficult to ensure completely consistent physical properties during ball manufacturing, thus affecting overall positioning performance.

[0003] Conventional solutions include regularly replacing the rubber ball bearing, using higher-quality rubber materials, and increasing maintenance frequency. However, these methods increase operating costs and do not fundamentally solve the problem of rubber ball bearing wear and aging. Regular replacement, while ensuring a certain level of positioning accuracy, leads to high material and labor costs due to frequent replacements. Using high-quality rubber materials can extend service life, but it is more expensive and cannot completely prevent wear and aging in extreme environments. Increasing maintenance frequency allows for timely detection and handling of problems, but it increases manpower and time costs and cannot completely prevent unexpected failures. Therefore, there is an urgent need for a convenient maintenance structure for the rubber ball bearing to address these issues. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a convenient maintenance structure for rubber ball bearings, and to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a convenient maintenance structure for a rubber ball, including: a pneumatic pump and a side support seat. The pneumatic pump is provided with a set of top seats for supporting it on the outer side of its lower end. The top seat has a diamond-shaped cross-section when viewed from above. The pneumatic pump is installed inside the middle position of the top seat, and the airflow release end of the pneumatic pump is located at the lower end of the top seat. A threaded inner groove is opened on the outer side, and an inner bearing seat is provided inside the threaded inner groove.

[0006] The inner bearing includes a threaded connecting post and a flow hole. The threaded connecting post has an external thread on its outer side. The upper outer side of the threaded connecting post is screwed into the inner groove thread. An air chamber for guiding air from the air pump is opened inside the threaded connecting post. A set of connectors for penetrating the interior of the top inflation end of the rubber ball is provided at the lower end of the threaded connecting post. Several sets of inner abutments for supporting the interior of the top inflation end of the rubber ball are provided on the outer side of the upper end of the connectors.

[0007] In a preferred embodiment, several sets of inner abutment seats are evenly distributed, and the lower end of the connector is provided with a set of sealing rings for sealing and fitting the inside of the inflatable end of the rubber ball.

[0008] In a preferred embodiment, the lower end of the sealing ring is provided with a set of flow holes for releasing and replenishing the air inside the rubber ball. The lower ends of the left and right sides of the top seat are respectively provided with a set of inner fitting grooves for positioning and engaging with the upper telescopic rod. When the worker needs to maintain the rubber ball, first adjust the extension height of the upper and lower telescopic rods according to the actual height of the rubber ball, and place the air pressure release end of the rubber ball at the top until the height between the top seat and the lower body is consistent with the height of the rubber ball to be maintained, and then make fine adjustments. Then, the worker inserts the inner support into the air pressure release end of the rubber ball, and then uses an air pump to pre-inflate the rubber ball so that the outer surface of the rubber ball is in contact with the inner surface of the two sets of side heating rollers. Then, the worker starts the motor, and the motor drives the lower body to rotate, so that the rubber ball follows the rotation of the lower body, and the two sets of side heating rollers are in contact with the outer surface of the rubber ball, melting and filling the uneven rubber material on the surface, thereby completing the repair and maintenance of the outer surface of the rubber ball.

[0009] In a preferred embodiment, each set of the inner fitting grooves is provided with a set of upper telescopic rods for adjusting the height of the top seat, and the lower end of the upper telescopic rods is provided with a set of side heating rollers for welding and maintaining the outer side of the rubber ball.

[0010] In a preferred embodiment, the upper and lower sides of the side heating roller are respectively provided with a set of inner limiting bearings for movably connecting with the outer side of the lower end of the upper telescopic rod and the outer side of the upper end of the lower telescopic rod. Each set of the upper telescopic rod, the lower telescopic rod and the side heating roller constitutes a set of side support components.

[0011] In a preferred embodiment, the side support assembly is provided in two sets to support the lower end of the top seat. Each set of the side support assembly has a set of side support seats at its lower end for supporting its lower end. The inner side of the two sets of side support seats is provided with a set of motor housing for protecting the motor.

[0012] In a preferred embodiment, the motor housing is provided with a set of motors for driving the download body to rotate and move.

[0013] In a preferred embodiment, the download body has a circular cross-section when viewed from above, and has a groove inside for supporting the bottom of the rubber ball. Inside the groove, there is a set of inner support springs for inner lining support and limiting the bottom of the rubber ball. When the worker puts the bottom of the rubber ball into the groove inside the download body, the inner support springs will adaptively support it according to the degree of expansion of the bottom of the rubber ball, so as to ensure that the bottom of the rubber ball and the download body maintain a certain fit, thereby ensuring that the rubber ball will not fall off during rotation, thus ensuring normal maintenance work.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: by inserting the inner support into the air pressure release end of the rubber ball, the worker then uses an air pump to pre-inflate the rubber ball, so that the outer surface of the rubber ball is in contact with the inner surface of the two sets of side heating rollers. Then, the worker starts the motor, and the motor drives the download body to rotate, so that the rubber ball follows the download body to rotate, and the two sets of side heating rollers are in contact with the outer surface of the rubber ball, melting and filling the uneven rubber material on the surface, thereby completing the repair and maintenance of the outer surface of the rubber ball;
