Description

TECHNICAL FIELD

[0001] The utility model relates to a tire production equipment field, in detail is a kind of anti-falling type bead storage rack device. BACKGROUND

[0002] It is known that the role of the boss under the lead screw of the tire production storage rack in the bead equipment and its importance, the role of the boss under the lead screw of the storage rack directly affects the normal work of the equipment, when the lead screw is running, the lead screw produces torsional vibration, when the natural frequency of its vibration makes other components resonate, noise will be produced, which not only pollutes the environment, but also seriously damages human health;In addition, the lead screw runs under the load of 6 steel wires, produces huge tension, the current fixing mode of the lead screw only relies on the locking nut above the lead screw, the lead screw produces friction twist for a long time, which easily causes the wear of the locking nut on the upper end of the lead screw, causes the falling of the lead screw, and affects the personal safety of the operating personnel. SUMMARY

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a kind of anti-falling type bead storage rack device, can prevent the falling in the movement process of lead screw.

[0004] The utility model discloses the technical scheme that solves its technical problem is: a kind of anti-falling type bead storage rack device, be equipped with lead screw fixed support, the lower part of lead screw fixed support is fixed with storage rack lower axle base, the upper part of lead screw fixed support is fixed with storage rack upper axle base, characterized in that, the boss hole of circular is processed on storage rack lower axle base, cylindrical lower boss is installed in boss hole, lower boss is fixed together with storage rack lower axle base, the center of lower boss is processed with the lead screw hole, the upper part of lead screw hole is processed with the circular step, push bearing is placed on step, storage rack lead screw is inserted in push bearing, storage rack lead screw is installed on storage rack upper axle base, and push bearing is installed between storage rack lead screw and the lead screw hole of lower boss.

[0005] The utility model has the advantages that the assembly mode of hole shaft cooperation is used between each component to facilitate assembly and replacement, push bearing is arranged to prevent the falling in the movement process of lead screw. BRIEF DESCRIPTION OF DRAWINGS

[0010] In the figure, the utility model is provided with screw fixing support 5, the lower part of which is fixed with storage rack lower shaft table 9, and the upper part of which is fixed with storage rack upper shaft table 6. A circular boss hole is processed on storage rack lower shaft table 9, and a cylindrical lower boss 1 is installed in the boss hole. The lower boss 1 is arranged at the lower end of storage rack screw 7 and is used to cooperate with storage rack lower shaft table 9 to form a stable support point. The circular edge of lower boss 1 is fixed with storage rack lower shaft table 9 through a bolt, and a screw hole is processed in the center of lower boss 1. A circular step 3 is processed in the upper part of the screw hole, and the step 3 is used to position thrust bearing 4. The lower part of storage rack screw 7 is inserted into thrust bearing 4, and thrust bearing 4 is installed on lower boss 1 to bear the axial load of storage rack screw 7 and reduce the risk of falling of storage rack screw 7. The upper part of storage rack screw 7 is installed on storage rack upper shaft table 6 through a bearing assembly. A screw sleeve 8 is installed between storage rack screw 7 and the screw hole of lower boss 1. The bearing outside the screw sleeve 8 is limited at the lower end of lower boss 1 through hole stopper 2, and the screw sleeve 8 is sleeved outside storage rack screw 7 to protect the screw from external damage. Hole stopper 2 is installed around the screw hole of lower boss 1 to limit the axial movement of storage rack screw 7 and enhance the fixing effect. Storage rack lower shaft table 9 is located at the lower part of the storage rack and cooperates with lower boss 1 to form an anti-falling structure.
