Abstract
Description
Technical Field
[0001] The utility model relates to the field of tire production equipment, in particular to an expansion and contraction type tire bead storage vehicle, which is used for storing large-sized tires such as engineering radial tires and jumbo tires. Background Art
[0002] As we all know, in the field of tire manufacturing, a tire consists of components such as the tread, carcass, sidewall, and bead. The entire vehicle load is borne by the tire mounted on the rim. The bead is the part of the tire that contacts the rim, and its quality plays a crucial role in the tire's dynamic performance and service life. Due to the large and heavy beads of OTR tires and jumbo tires, improper storage can easily cause deformation. This leads to poor bead alignment during tire production, and deformation can cause defects such as bubbles and glue shortages due to uneven material distribution, seriously affecting the product's service life.
[0003] The tire beads are stacked freely in multiple layers on a flat rack, and are separated by bead spacers. Under the action of the tire bead's gravity (the heaviest bead is about 130 kg / piece), the layers are compacted and severely deformed. There is adhesion and stretching elliptical deformation during use and removal. The deformed position is extremely difficult to restore to its original state during the production process. During the production and use of the tire, the tire bead is in close contact with the rim and is subjected to very large forces. The rubber material at the bead heel is uneven in thickness due to the deformation of the bead, and there are defects such as internal bubbles and lack of rubber. The tire heel generates a lot of heat during use. When the heat accumulates to a certain level, it causes performance degradation and early damage to the tire. Summary of the Invention
[0004] In order to overcome the shortcomings of the existing technology, the utility model provides an expanding and contracting tire bead storage cart, which can solve the problems of tire bead being freely stacked in multiple layers on a flatbed cart, resulting in compaction and serious deformation between layers, adhesion and tensile deformation during use and removal, and difficulty in restoring to the original state during production, thereby improving the elliptical accuracy of tire bead storage.
[0005] The technical solution adopted by the utility model to solve its technical problems is: an expanding and contracting tire bead storage vehicle is provided with a base frame, a supporting vertical frame is fixed in the middle of the base frame, and its characteristic is that an expanding and contracting device support frame is installed on the upper half of the supporting vertical frame, and a guide support frame is horizontally installed on the expanding and contracting device support frame at the upper position of the supporting vertical frame, and a sliding bearing is set at the end of the guide support frame, and the sliding bearing is connected to the expanding and contracting device guide bracket, and the sliding bearing drives the expanding and contracting device guide bracket to retract and retract, and a fixed roller frame perpendicular to the direction of the guide support frame is symmetrically provided at the top position of the supporting vertical frame, and fixed roller brackets are respectively installed on the fixed roller frames, and the fixed roller brackets are arranged in an orderly interval by the fixed device movable roller shaft, the fixed device movable roller fixing wire, and the fixed device movable roller spacer to form two groups of fixed roller roller groups, and the expanding and contracting device support frame and the fixed roller are connected. The two ends of the two short links are hinged to each other at one end, and the other end of the two short links is hinged to the inner side of the two long links by a rolling bearing sleeve. The middle intersection of the two long links is hinged to the link positioning frame via a rotating shaft. The front ends of the two long links are embedded in the bearing sleeve guide groove of the front expansion and contraction device movable plate through rolling bearing sleeves, and the rear ends of the two long links are embedded in the bearing sleeve guide groove of the rear expansion and contraction device movable plate through rolling bearing sleeves.

The base frame 1, the supporting frame 4, and the expansion and contraction device support frame 5 are reinforced and connected by the lower reinforcement support frame 6-1 and the upper reinforcement support frame 6-2. The expansion and contraction device support frame 5 is symmetrically installed on the upper position of the supporting frame 4 and is perpendicular to the supporting frame 4. A guide support frame 7 is installed horizontally at the end of the guide support frame 7. A sliding bearing 8 is set at the end of the guide support frame 7. The sliding bearing 8 is connected to the expansion and contraction device The guide bracket 9 is connected, and the sliding bearing 8 drives the expansion and contraction device guide bracket 9 to slide and retract. Fixed roller frames 10 perpendicular to the direction of the guide support frame 7 are symmetrically provided on both sides of the top position of the support frame 4. Fixed roller brackets 11 are respectively installed on the fixed roller frames 10. The front and rear sides of the fixed roller bracket 11 are arranged in an orderly manner through the fixed device movable roller shaft 15, the fixed device movable roller fixing wire 16, and the fixed device movable roller spacer 17 to form two groups of fixed roller groups. A connecting rod positioning frame 18 is installed on the support frame 4 between the expansion and contraction device support frame 5 and the fixed roller frame 10. The connecting rod positioning frame 18 is connected to the adjusting screw 20 through the adjusting screw positioning cover 19, the adjusting screw 20 is screwed with an adjusting nut 22, and the end of the adjusting screw 20 is installed with an adjusting handwheel 21. The adjusting handwheel 21 drives the adjusting nut 22 to make a linear motion on the adjusting screw 20. The adjusting nut 22 is hinged to one end of the two short connecting rods 23, and the other end of the two short connecting rods 23 is hinged to the inner side of the end of the two long connecting rods 24 through a rolling bearing sleeve 25. The middle intersection of the two long connecting rods 24 is hinged to the connecting rod positioning frame 18 through the rotating shaft. The front end of the two long connecting rods 24 is embedded in the bearing sleeve guide groove 27 of the front expansion and contraction device movable plate 26 through the rolling bearing sleeve. The rear end of each long connecting rod 24 is embedded in the bearing sleeve guide groove 27 of the rear expansion and contraction device movable plate 26 through a rolling bearing sleeve, and the front expansion and contraction device movable plate and the rear expansion and contraction device movable plate are respectively connected to the front and rear expansion and contraction device guide brackets 9, and the expansion and contraction device guide brackets 9 are arranged in an orderly interval through the expansion and contraction device movable roller shaft 28, the expansion and contraction device movable roller spacer sleeve 30 and the expansion and contraction device movable roller 13 and are fastened and installed with the expansion and contraction device guide bracket 9 through the expansion and contraction device movable roller fixing wire 29 to form two groups of movable roller groups, with a total of 2 groups of fixed roller groups and 2 groups of movable roller groups. A limit stop rod 12 is fixed to the upper right end of the fixed roller frame 10.
[0019] By adjusting the hand wheel 21 to drive the adjusting nut 22, the short connecting rod 23 and the long connecting rod 24 are driven to move on the adjusting screw 20 with the connecting rod positioning frame 18 as the center. The rolling bearing sleeves 25 installed at the four ends of the long connecting rod 24 are embedded in the bearing sleeve guide groove 27. The rolling bearing sleeve 25 makes a linear motion parallel to the adjusting screw 20 along the bearing sleeve guide groove 27. Under the guiding action of the sliding bearing 8, the expanding and contracting device movable roller shaft 28, the expanding and contracting device movable roller spacer 30, the expanding and contracting device movable roller 13, and the expanding and contracting device movable roller fixing wire 29 fixed on the expanding and contracting device guide bracket 9 are driven to make expansion and contraction movements along the guide support frame 7, thereby realizing the expansion and contraction function of the storage car, and stretching the tire bead during storage, effectively preventing the risk of tire bead extrusion deformation, extrusion adhesion and elliptical deformation, so as to ensure the tire bead accuracy, improve the durability of the tire bead, and eliminate the hidden dangers of early tire damage.
[0020] The specific operation plan is that the operator places the produced tire bead fitting parts on the fixed roller frame 10, and supports them through the fixed device movable roller 14 installed on the fixed roller bracket 11, the fixed device movable roller shaft 15, the fixed device movable roller fixing wire 16, and the fixed device movable roller spacer 17. They are placed on the fixed roller group and the movable roller group in an orderly spaced manner of one partition C and one tire bead D. The first group of partitions C and tire bead D are limited by the limiting lever 12 and are arranged one by one from the right side to the left. After the placement is completed, the adjusting hand wheel 21 is used to drive the adjusting nut 22 to move linearly left and right on the adjusting screw 20 under the support of the adjusting screw positioning cover 19. During the linear motion, the adjusting nut 22 drives the short connecting rod 23 connected to it, and is connected to the long connecting rod 24 through the rolling bearing sleeve. When the adjusting hand wheel 21 rotates, the adjusting nut 22 drives the short connecting rod 23 and the long connecting rod 24 to make linear motion on the adjusting screw 20 with the connecting rod positioning frame 18 as the center. The rolling bearing sleeves 25 installed at the four ends of the long connecting rod 24 are in the bearing sleeve guide groove 27, and make linear motion parallel to the adjusting screw 20, thereby driving the expansion and contraction device guide bracket 9 and the expansion and contraction device movable roller 13 to do expansion motion (such as Figure 1 、 Figure 4A in the figure is the expansion limit state), thereby realizing the expansion function of the storage vehicle, after the inner diameter of the tire bead D is adjusted to a position that matches the inner diameter size by the support of the movable roller 14 of the fixing device and the tension of the movable roller 13 of the expansion and contraction device, the self-locking directional wheel 2 and the self-locking steering wheel 3 are released and pulled to the tire bead storage area or machine for use. When in use, while adjusting the adjustment hand wheel 21 in the opposite direction, the adjustment nut 22 is driven to drive the short connecting rod 23 and the long connecting rod 24 to make opposite linear motion on the adjusting screw 20 with the connecting rod positioning frame 18 as the center. The rolling bearing sleeves 25 installed at the four ends of the long connecting rod 24 make opposite linear motion in the bearing sleeve guide groove 27 in the direction parallel to the adjusting screw 20, thereby driving the expansion and contraction device guide bracket 9 and the expansion and contraction device movable roller 13 to make a closing motion along the guide support frame 7 (as shown in FIG. Figure 1 、 Figure 3 (B is the closed initial state, shown in the figure), thus achieving the reduction function for the storage vehicle. After the bead inner diameter is reduced to a position smaller than the inner diameter of the bead D by the support of the fixing device movable roller 14 and the reduction of the movable roller 13 of the expansion and contraction device, the bead is removed and the expansion function is completed again to ensure the dimensional stability of the bead D during storage, thus completing the entire process of expanding the bead for storage and reducing it for removal. The risks of bead extrusion deformation, extrusion adhesion, and elliptical deformation are effectively prevented, thereby ensuring the bead accuracy, improving the bead durability, and eliminating the potential risk of early tire damage.
