Prestress tensioning equipment
The invention provides prestress tensioning equipment, and belongs to the technical field of road and bridge construction equipment. The equipment comprises a cylinder sleeve, a first tensioning cylinder body and a second tensioning cylinder body, the first tensioning cylinder body is located between the second tensioning cylinder body and the cylinder sleeve, a first hydraulic cavity is formed between the cylinder sleeve and the first tensioning cylinder body, a second hydraulic cavity is formed between the first tensioning cylinder body and the second tensioning cylinder body, and a plurality of cable penetrating units are arranged on the second tensioning cylinder body. The cable penetrating unit comprises a steel strand guide sleeve, a balance piston fixed to the steel strand guide sleeve, a balance sliding hole formed in a cylinder body bottom plate of the second tensioning cylinder body and an anchoring plate fixed to the second tensioning cylinder body. The outer end of the steel strand guide sleeve is provided with a first conical clamping piece plug capable of fixing the steel strand penetrating through the steel strand guide sleeve in a one-way mode. A closed balance cavity is formed between the anchoring plate and the cylinder body bottom plate of the second tensioning cylinder body, all the balance sliding holes communicate with the balance cavity, and the prestress tensioning equipment has the advantages that all the steel strands can be evenly stressed.
本发明提供了一种预应力张拉设备，属于路桥施工设备技术领域。包括缸套、第一张拉缸体和第二张拉缸体，第一张拉缸体位于第二张拉缸体与缸套之间，缸套与第一张拉缸体之间具有第一液压腔，第一张拉缸体与第二张拉缸体之间具有第二液压腔，第二张拉缸体上具有多个穿索单元，穿索单元包括钢绞线引导套、固定在钢绞线引导套上的平衡活塞、开设在第二张拉缸体的缸体底板上的平衡滑孔和固定在第二张拉缸体上的锚定板，钢绞线引导套的外端设置有能够对穿过钢绞线引导套的钢绞线进行单向固定的第一锥形夹片塞；锚定板与第二张拉缸体的缸体底板之间形成一密闭的平衡腔，各平衡滑孔均与平衡腔相通，本发明具有能够使各钢绞线受力均匀等优点。
