Description

Technical Field

[0001] The utility model relates to the technical field of cement pipes, in particular to a socket-and-spigot type cement pipe mould. Background Art

[0002] Cement pipes are also called cement pressure pipes and reinforced concrete pipes. They can be used as sewage pipes in urban construction foundations, for flood control and drainage, as well as water pipes and farmland wells used in some special factories and mines. During the production of cement pipes, in order to increase their strength, steel cages are added to the mold, and the steel cages are buried in the cement pipes after pouring.

[0003] Most of the existing cement pipe molds use manual positioning to place the steel cage at the work station. The next step is to let the forklift master take the outer cylinder to cover the steel bars, and then use an external crane to place the inner mold cylinder for positioning.

[0004] There are some problems. For example, a single mold cannot realize continuous cement pipe production operations in a short period of time. The steel cage cannot be automatically and accurately placed between the outer mold and the inner mold. The positioning method is single and there will be a certain degree of deviation, which will affect the strength and stability of the cement pipe. The manual participation time is long and the repetitiveness is strong. For this reason, we propose a socket-type cement pipe mold. Utility Model Content
