[0026] It should be noted that the bias tire blank 500 is placed upright on the mobile chassis 100, and the bias tire blank 500 is supported by the lifting assembly 300 and the hoisting assembly 400 to avoid deformation of the blank and ensure the quality of the bias tire product; at the same time, the bias tire blank 500 is convenient to move with the help of the mobile chassis 100 and the rotatable suspension arm 200, reducing the labor intensity of workers; in addition, the hoisting assembly 400 can support bias tire blanks 500 of various specifications, and has a wide range of applications. Preferably, the lifting assembly 300 is a manual hoist.

[0027] In the bias tire blank transport device of this embodiment, please refer to Figures 1 to 3The rotatable suspension arm 200 includes a support frame, a column 201 and a crossbeam 202. The support frame is connected to the mobile chassis 100. At the same time, the interior of the support frame is a cavity. The bottom of the column 201 can be rotatably embedded in the interior of the support frame, and the top of the column 201 is connected to the lifting assembly 300 through the crossbeam 202.

[0028] Specifically, the bottom of the column 201 is set to a conical structure to reduce the rotation resistance. At the same time, in order to assist manual operation and more labor-saving rotation of the column 201, a rotating handrail is set on the column 201. In addition, a reinforcing rib is set between the crossbeam 202 and the column 201 to enhance stability.

[0029] In the bias tire blank transport device of this embodiment, please refer to Figure 1 to Figure 2 The mobile chassis 100 is provided with a hook 101 and / or a handle 102 for easy movement.

[0030] In the bias tire blank transport device of this embodiment, please refer to Figures 1 to 6 The hoisting assembly 400 includes a guide rod 402 and a fixed plate 403. The outer sleeve of the guide rod 402 is provided with a guide sleeve 404 that can slide along its axial direction. The bottom of the guide rod 402 is connected to the fixed plate 403. The support shoe 401 is set to an arc structure that matches the curvature of the tire shoulder to support the bias tire blank 500. The support shoe 401 is rotatably connected to the fixed plate 403 and the guide sleeve 404 respectively.

[0031] It should be noted that the support tile 401 can rotate relative to the fixed plate 403 and the guide sleeve 404 to change the angle between the support tile 401 and the guide rod 402 to adapt to different specifications of the bias tire blank 500; at the same time, the support tile 401 is set to an arc structure that matches the curvature of the tire shoulder, which can reduce the deformation of the bias tire blank 500 and ensure the quality of the bias tire product. In addition, a lifting ring 408 is set above the guide rod 402, and the lifting ring 408 is connected to the hook end of the lifting assembly 300.

[0032] In the bias tire blank transport device of this embodiment, please refer to Figures 1 to 6 The guide rod 402 is provided with a plurality of first positioning holes along its axial direction, the guide sleeve 404 is provided with a second positioning hole, and a positioning pin is connected between the first positioning hole and the second positioning hole.

[0033] It should be noted that when the positioning pin is pulled out, the guide sleeve 404 drives the support shoe 401 to slide down along the axial direction of the guide rod 402 under the action of its own gravity; and when the positioning pin is inserted, the guide sleeve 404 can be locked.

[0034] In the bias tire blank transport device of this embodiment, please refer to Figures 1 to 6 The hoisting assembly 400 also includes a plurality of limit rods 407 symmetrically arranged around the central axis of the guide sleeve 404 . The limit rods 407 are located above the support shoe 401 and connected to the guide sleeve 404 .

[0035] It should be noted that the multiple support tiles 401 are arranged in a circle, that is, the multiple support tiles 401 are located on the same circumference to form a support ring. As the angle between the support tile 401 and the guide rod 402 changes, the diameter of the support ring changes accordingly to adapt to tire blanks of different specifications.

[0036] Specifically, the diameter of the support ring is calculated based on the inner diameter of the bias tire blank and the diameter of the maximum blank support point.

[0037] The minimum tire inner diameter is 24 (inch) × 25 = 600mm-20mm (reserved gap) = 580mm;

[0038] The maximum tire embryo support point diameter is 32 (inches) × 25 = 800mm + 100mm (tire shoulder position) = 900mm;

[0039] Therefore, the diameter of the support ring is 580 mm-900 mm. Figure 6 The support ring is in the smallest diameter state. At this time, the angle between the support shoe 401 and the guide rod 402 is the smallest. Figure 5 The support ring is in the largest diameter state. At this time, the angle between the support shoe 401 and the guide rod 402 is the largest.

[0040] In the bias tire blank transport device of this embodiment, please refer to Figures 1 to 6 The support shoe 401 is connected to the fixed plate 403 via a first connecting rod 405 , and the first connecting rod 405 is connected to the guide sleeve 404 via a second connecting rod 406 .

[0041] It should be noted that the bottom of the first connecting rod 405 is rotatably connected to the fixed plate 403 , the middle of the first connecting rod 405 is rotatably connected to one end of the second connecting rod 406 , and the other end of the second connecting rod 406 is rotatably connected to the guide sleeve 404 .

[0042] In the bias tire blank transport device of this embodiment, please refer to Figures 1 to 6 The lengths of the limiting rod 407 and the first connecting rod 405 are both greater than the radius of the bias tire blank opening, and the diameter of the fixing plate 403 is smaller than the diameter of the bias tire blank opening.

[0043] While working, see Figures 1 to 6The bias tire blank is stored vertically. When the support ring has the smallest diameter, it is positioned by a positioning pin. The lifting assembly 300 is manually started so that the limit rod 407 overlaps the tire shoulder. The positioning pin is manually pulled out, and the guide sleeve 404 automatically moves downward due to its own gravity. The lifting assembly 300 is manually started to rise, driving the fixed plate 403 to move upward. The fixed plate 403 drives the support tile 401 and the first connecting rod 405 to move upward, and the guide sleeve 404 drives the second connecting rod 406 downward. The two reverse operations drive the first connecting rod 405 and the second connecting rod 406 to expand outward until the support tile 401 contacts and supports the bias tire blank, completing the tire blank support process. When the bias tire blank is transported to the vulcanizer, it is manually lowered so that the limit rod 407 overlaps the tire shoulder. At this time, the guide sleeve 404 stops descending. The lifting assembly 300 continues to descend, and the fixed plate 403, the guide rod 402 and the first connecting rod 405 descend under the action of their own weight, so that the support shoe 401 approaches the guide rod 402, the support ring is reduced to the smallest diameter state, the first positioning hole is aligned with the second positioning hole, and the positioning pin is manually inserted. The lifting assembly 300 is started to rise, so that the fixed plate 403 leaves the bias tire blank. The rotating handrail is rotated to drive the column 201 and the crossbeam 202 to rotate, and the lifting assembly 400 is moved to the waiting position to facilitate the vulcanizer manipulator to descend and grab the tire.

[0044] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
