A suspension bridge pylon top main cable saddle hoist device and construction method are provided, According to the tower top structure, a group of hoisting brackets are arranged on the tower top, thetruss structure is adopted, the pre-embedded cross beam is used as the foundation of the brackets, the single cross beam is strengthened by double-splicing I-steel upper surface covering steel plate,and the two cross beams are connected with steel bars to enhance the stability; According to the weight of the main cable saddle, a 8t winch is used to hoist the main cable saddle by using multiple wire ropes, and a group of traveling cranes are arranged on the brackets so as to translate the main cable saddle into position. By using the lifting and installing device, the small working surface ofthe tower top construction is overcome, the conventional lifting device cannot meet the lifting weight requirements, the working efficiency is improved, the construction accuracy and safety of the main cable saddle are guaranteed, and the lifting and installing device has the construction superiority.
Description
technical field [0001] The invention relates to the technical field of engineering surveying, in particular to a hoisting device and a construction method for a main cable saddle on a tower top of a suspension bridge tower. Background technique [0002] In the construction process of the suspension bridge, in order to erect permanent structures such as saddles and main cables, and construct temporary facilities such as catwalks, traction systems, and cable-strand tensioning systems, the construction work area on the top of the tower is small, and the designed main cable saddle is heavy. Traditionally used conventional hoisting equipment has the disadvantages of being difficult to accurately adjust the position of the main cable saddle, the height of the cable tower is large, and the working surface on the top of the tower is narrow and inconvenient for construction. Therefore, it is very practical to use a hoisting device to install the main cable saddle safely and reliably ...
