Description

Technical Field

[0001] The utility model relates to the technical field of turnover machines, in particular to a cavity wall prefabricated component turnover machine. Background Art

[0002] Cavity wall is a commonly used precast concrete component, which generally includes two opposite precast concrete panels and a steel cage connected between the two precast concrete panels. In the prior art, the production principle of cavity wall is generally as follows: the A-side component is cast on the formwork, and after the steel cage is embedded, it is sent to the curing kiln for the first curing; after the curing is completed, the B-side component is cast, and the cured A-side component is turned 180° and placed on the B-side component.

[0003] In the prior art, there are mainly two ways to fix the A-surface component:

[0004] The first method is to use a pressure plate to press the A-side component. The pressure plate is generally bulky and needs to be manually inserted and removed, which is time-consuming and labor-intensive. Manual insertion and removal of the pressure plate is also not in line with the trend of future development;

[0005] The second method is to use a suction cup to hold the A-side component. This method requires the A-side component to be transferred to the suction cup first, which requires additional lifting equipment, is costly, and the component may shift during the transfer process, affecting the mold clamping accuracy. Utility Model Content

[0006] The purpose of the utility model is to provide a cavity wall prefabricated component flipping machine, which can clamp, lift and flip the A-side components through the mold table clamping and flipping mechanism.
