Description

Technical Field

[0001] This utility model relates to the technical field of non-vacuum tire disassembly and assembly tools, and in particular to non-vacuum tire disassembly and assembly lines for engineering machinery and wide-body vehicles. Background Technology

[0002] In the field of construction machinery and wide-body vehicles, the installation and removal of non-vacuum tires is a crucial step in ensuring the normal operation of equipment. Due to the large size, heavy weight, and complex structure of non-vacuum tires, traditional installation and removal processes rely heavily on manual labor or semi-automated equipment.

[0003] In existing technologies, the tire separation process typically employs a manual-assisted mechanical pushing method to forcibly separate the tire from the rim. This process has significant drawbacks: firstly, manual operation requires frequent adjustments to the tire position and relies on worker experience to control the separation force, resulting in low separation efficiency and a long separation time per tire; secondly, the high degree of human intervention leads to insufficient tire positioning accuracy during separation, easily causing damage to the rim or tire edges and increasing the wear rate of parts. This low-automation and low-efficiency separation method not only limits the overall capacity of the assembly and disassembly line but also makes it difficult to meet the needs of large-scale production due to the high intensity of manual labor, becoming a key bottleneck restricting the improvement of tire maintenance efficiency for construction machinery. Therefore, these problems need to be addressed. Utility Model Content

[0029] Working principle: In use of this utility model, a drive motor is externally connected to the tire conveyor roller 44, the hub conveyor roller 45, and the side where the conveyor roller 46 and the discharge conveyor roller 47 are installed. The equipment is powered on, and the tire is transported to the separation disc 7 in the tire separator frame 1 through the external conveyor rollers. Since the first universal ball 8 is installed on the upper end of the separation disc 7, the first tilting cylinder 6 is activated. The up and down movement of the first tilting cylinder 6 drives the separation disc 7 to correct the tire back and forth, so that the tire is fixed by the first fixed platform 9. The first electric push cylinder 4 is activated to lift the first support platform 5 to the lower end of the separation disc 7. Then, the separation cylinder 11 installed on the upper end of the fixed plate 10 is activated. The separation cylinder 11 separates the tire and the hub. Due to gravity, the hub passes through the wheel. The wheel is inserted into the first support platform 5 through the through hole opened on the axis of the separating disc 7. Then, the first electric push cylinder 4 is reset, driving the first support platform 5 to move down. The external drive motor is manually started. The wheel hub is checked. If the wheel hub is damaged, it is manually replaced and then pushed to the wheel hub transfer roller 45. The tire is checked. If the tire is damaged, it is manually replaced and then pushed to the tire transfer roller 44. The tire reaches the fitting disc 29 installed at the upper end of the tire fitting frame 2.

On the rotating platform 21, the second electric push cylinder 20, installed on the upper end of the first mounting platform 19, is activated to raise the first lifting platform 52 a certain distance. The stepper motor 53 then drives the first bevel gear 54 to drive the second bevel gear 55, thereby rotating the rotating platform 21 to rotate the hub to a suitable mounting angle. The stepper motor 53 is then turned off, and the second electric push cylinder 20 is reset, allowing the hub to be placed on the conveying platform 22. The first drive electric push cylinder 17 and the second drive electric push cylinder 49, respectively installed on one side of the first abutment platform 16 and the second abutment platform 48, are activated to push the conveying platform 22 into the second empty chamber 14 via the first sliding platform 15 and the second sliding platform 18.

The platform 25 is pushed up, and the fourth electric pusher cylinder 26 installed on the upper end of the second lifting platform 25 is activated to push up the second support platform 27, raising the wheel hub placed on the upper end of the conveying platform 22. Then the components in the first empty chamber 13 are reset. The fourth electric pusher cylinder 26 continues to push up the second support platform 27 to combine the wheel hub with the outer tire. The assembled tire passes through the installed conveyor roller 46 to reach the tire pressing frame 3. The assembled tire is moved on the locking platform 36 by rotating the wheel 51. The fifth electric pusher cylinder 39 installed at the front end of the third fixed platform 37 is activated. The fifth electric pusher cylinder 39 pushes the limiting platform 38 to fix the assembled tire. The seventh electric pusher cylinder 33 installed on the third mounting platform 32 is activated to push up the pressing platform 34 to install the retaining ring 35 on the tire.After the locking ring is manually positioned and installed in advance on the locking ring platform 43, the sixth electric pusher cylinder 41, installed on the fourth mounting platform 40, drives the third lifting platform 42 to move down and install the locking ring on the tire. After installation, the fifth electric pusher cylinder 39, the seventh electric pusher cylinder 33, and the sixth electric pusher cylinder 41 are reset. Subsequent tires will then push the installed tires to the discharge conveyor roller 47 to deliver the installed tires.
