Jackstay device

Abstract

The invention discloses a jackstay device. The jackstay device comprises a jackstay unit. A carrying wheel support comprises a plurality of carrying support plates arranged side by side. The left side and the right side of the carrying wheel support is each fixedly provided with a carrying shaft sequentially penetrating through the carrying support plates. Carrying wheels corresponding in number and position are arranged in the positions, between every two adjacent carrying support plates, of the two carrying shafts. A cable rope hanger comprises a plurality of cable rope hanging plates arranged side by side. A hanger long shaft penetrating through all the cable rope hanging plates in sequence is arranged at the upper end of the cable rope hanger. The cable rope hanger is hinged to the middle of the carrying wheel support through the hanger long shaft. The cable rope hanger is further provided with an upper jackstay long shaft and a lower jackstay long shaft which sequentially penetrate through all the cable rope hanging plates. An upper jackstay wheel is arranged on the upper jackstay long shaft. A lower jackstay wheel is arranged on the lower jackstay long shaft. Each upper jackstay wheel corresponds to the corresponding lower jackstay wheel up and down. Through the jackstay device, the technical problem that pulling ropes and hoisting ropes of pulling hoisters hang down excessively or bother each other can be solved.

Description

technical field [0001] The invention relates to the technical field of a cable supporting device used for a cable crane in a bridge building process, in particular to a supporting device for supporting a cable. Background technique [0002] In the process of constructing a long-span bridge, it is necessary to set up a cable crane on both sides of the construction site and install a sports car for hoisting. Below the cable, there are traction cables and hoisting cables suspended between the sports cars of the cable crane. In order to prevent excessive sagging or mutual disturbance between the traction rope and the hoisting rope, a supporter is usually provided on the main cable, and the traction rope and the hoisting rope are suspended on the main cable through the supporter. But the existing cable support is simple in structure, and the cable support is a fixed shape, and the shape of the cable support cannot produce corresponding changes with the inclination of the main cab...

AI Technical Summary

Problems solved by technology

But the existing cable support is simple in structure, and the cable support is a fixed shape, and the shape of the cable support cannot produce corresponding changes with the inclination of the main cable. There is a dead angle in the sliding range of the main cable, and the support The rope catch cannot be slid to both ends of the main rope

[0003] The existing cable crane used for component installation pulls the sports car through the traction cable to realize the operation in the span direction on the load-bearing cable, but the original sports car is heavy and inconvenient to install, and the cable crane is mostly located in complex terrain, without suitable installation tools Increased the difficulty of installation
