Zusammenfassung: | The utility model relates to a special gland for a double-rubber-ring steel spigot for core mold vibration, in particular to a double-rubber-ring steel spigot assembling tool. According to the special gland, a pretightening limiting device is arranged on a rolling disk, the double-rubber-ring steel spigot is fixed to the rolling disk by clamping a rubber ring groove in the spigot, and finally the double-rubber-ring steel spigot is assembled onto a concrete pipeline. The special gland is composed of a lifting hydraulic cylinder (1), a swing arm (2), a first rolling telescopic rod (3), a second rolling telescopic rod (4), a ball journal (5), the rolling disk (6) and fixing bolt pins (7). By adopting the special gland, the double-rubber-ring steel spigot can be well assembled onto the concrete pipeline on a core mold vibration equipment mold; meanwhile, the quality of products and convenience of concrete mold dismantling are guaranteed, and the production efficiency of pipelines is improved. |
