Tensioning equipment and tensioning method for fork lug type steel strand
The invention discloses tensioning equipment for a fork lug type steel strand. The tensioning equipment comprises a first mounting piece, a second mounting piece and an adjusting device, the first mounting piece and the second mounting piece are fixedly connected with two parts of the fork lug type steel strand, the distance of which is to be adjusted; the adjusting device comprises an adjusting rope and a jack; the jack is arranged at one end of the first mounting piece; the first end of the adjusting rope is connected to the other end of the first mounting part, the adjusting rope bypasses the second mounting part, and the second end of the adjusting rope penetrates through the first mounting part and is connected to the jack; the jack is used for pulling the second end of the adjusting rope away from the first installation piece so as to drive the first installation piece to be close to the second installation piece. According to the tensioning equipment, the two parts with the adjustable distance in the fork lug type steel strand can be close to each other only by pulling the steering adjusting rope through one jack, a user can conveniently adjust the fork lug type steel strand to be tensioned, the pretension force of the steel strand is improved, and the tensioning equipment is simple in structure and convenient to use by the user. The invention further discloses a tensioning method of the fork lug type steel strand.
本发明公开一种叉耳式钢绞线的张拉设备，包括第一、二安装件和调节装置；第一、二安装件分别与叉耳式钢绞线中待调节距离的两部分固定连接；调节装置包括调节绳和千斤顶；千斤顶布置于第一安装件的一端；调节绳中第一端连接于第一安装件的另一端，并且调节绳绕过第二安装件，其第二端穿过第一安装件并连接于千斤顶；千斤顶用于牵拉调节绳的第二端远离第一安装件，以驱动第一安装件靠近第二安装件。上述张拉设备仅利用一个千斤顶牵拉转向的调节绳即可实现使叉耳式钢绞线中距离可调的两部分相互靠近，方便用户调节该叉耳式钢绞线至张紧并提高钢绞线的预拉力，并且该张拉设备的结构简单，方便用户使用。本发明还公开一种叉耳式钢绞线的张拉方法。
