Description

Technical Field

[0001] The utility model relates to the technical field of glass production, in particular to a turning platform structure. Background Art

[0002] Laminated glass is a special composite glass product, which consists of one or more layers of organic polymer interlayers sandwiched between two or more pieces of glass. The glass of this product needs to be pre-pressed at a special high temperature (or vacuumed) before being unloaded by a special loading trolley. The loading trolley is pushed along two pre-buried tracks to the inside of a high-temperature and high-pressure pressure vessel (autoclave) for processing, so that the glass and the interlayer are tightly bonded together and finally become a finished product. Before packing, the finished laminated glass on the loading trolley needs to be manually rotated 90 degrees through the on-site transfer and steering platform and then transported to the glue repair process and packed.

[0003] The transfer and steering platform designed on site has a simple structure and poor load-bearing capacity. The center is centered by a tapered roller bearing, and the circumference is rolled by a deep groove ball bearing on the working surface below the ground. Foreign objects or rubber strips often fall on the working surface where the bearings roll, causing the platform to be unable to rotate normally. The platform needs to be hoisted by a crane and the foreign objects on the working surface need to be thoroughly cleaned before it can work normally.

[0004] On the other hand, with the increase of loading rate, the weight of the loading trolley increases greatly, which makes the platform easy to shake when entering or leaving the turning platform, the supporting bearings are easy to break, and there is a risk of derailment when the loading trolley passes by, which is not conducive to safe production. At the same time, it is very difficult for on-site operators to rely on manual steering, which is not conducive to reducing the intensity of manual labor.

[0005] After searching, the applicant found that the Chinese patent document with publication number 211643778U disclosed a turning platform for special-shaped sheet metal parts on October 9, 2020, including a rotating platform and a conveying mechanism, wherein the conveying mechanism is arranged on the rotating platform, and a rotating shaft for rotation is arranged in the middle of the rotating platform. The bottom of the rotating shaft is installed on the support frame through a bearing, and the bottom of the rotating platform is installed with the support frame through a rotating gear. A conveying groove is arranged on the upper part of the rotating platform, and a conveying mechanism is installed in the conveying groove; this device also cannot solve the above-mentioned technical problems.

[0006] Therefore, in order to improve or solve at least one of the above problems, it is necessary to optimize the existing turning platform structure. Utility Model Content
