Centrifugal concrete pile mold and flat car for shelving centrifugal concrete pile mold

Abstract

The invention relates to a centrifugal concrete pile mold which is composed of a mold body (1) folded by a lower half mold (11) and an upper half mold (12) and a mold closing bolt assembly (2) for connecting the lower half mold (11) and the upper half mold (12). A front supporting plate (3a) and a back supporting plate (3b) are separately fixed to a front end surface (1a) and a back end surface (1b) of the mold body (1). The mold body is characterized in that annular wedge-shaped surfaces (33) are arranged on the peripheries of the end surfaces, attached to the mold body (1), of the front supporting plate (3a) and the back supporting plate (3b). The mold is the centrifugal concrete pile capable of positioning mold closing of the mold precisely and provides probability that a mold hosting route and a centrifugal machine are on same axis, so that a centrifugal concrete pile production line is optimized favorably. The invention also relates to a flat car matched with the mold in use.

Description

technical field [0001] The invention relates to a mold for a centrifugal concrete pile and a flatbed truck for shelving the mold. Background technique [0002] Pretensioned prestressed centrifugal concrete pile is an important pile foundation material in my country, which belongs to the technical field of concrete products. Its factory production can be traced back to the 1960s. In the 1980s, with the As a kind of heavy-duty prefabricated component, its main process is to cut the steel bar to length, form the steel bar into a cage shape, install the end plate, put the steel bar cage with the end plate into the bottom mold, and clean the upper mold. And base formwork, coating release agent, concrete mixing, fabric distribution, mold clamping, tensioning, centrifugal forming, steam curing, formwork removal and other processes, in order to realize the factory production of centrifugal prefabricated piles, we need to adjust each The process is arranged to form a reasonable assembl...

Problems solved by technology

[0004] The fed and prestressed and stretched molds need to be hoisted horizontally to the centrifuge by a crane. The process of the mold on the assembly line is to move the mold from one operation point to another by the crane. When running between two-span factory buildings When it is used, it is mainly transported by trolley, that is, the mold is hoisted onto the trolley by a crane, and when it reaches another cross-factory, it is hoisted from the trolley to the work site. There are many control procedures, and the centrifuge and the trolley transportation line are not in the same On the axis, it must be misaligned, resulting in an increase in space. With the additional increase in space, it will also cause unreasonable and difficult layout of other related processes. For example, the length of the workshop will be extended, and the corresponding other related to the workshop Workshop procedures also need to be adjusted, so that the entire process layout is not compact, which also increases the workload of the cross-factory crane and causes work conflicts between multiple cranes

As a result, the production capacity of the processes in the multi-span workshop is unbalanced, and there is a waiting phenomenon in some operations, which is not convenient for the automation and intelligence of the centrifuge process.
