Problems solved by technology
[0002] At present, with the development of water transportation engineering construction technology, the hoisting technology of concrete components is becoming more and more mature. However, in the construction of ports and wharfs, most of them use rings and "inverted T-shaped booms" as spreaders to hoist concrete components. When the "inverted T-shaped boom" is hoisted, because the hoisting hole is reserved deep, it is easy to cause the installation of the spreader on land, the difficulty of removing the spreader underwater, and low work efficiency.

The invention relates to a large-scale prefabricated component hoisting device and method, which relate to the technical field of large-scale prefabricated component hoisting, and particularly belong to a device and a method for hoisting large-scale prefabricated components by using inverted T-shaped suspenders. It has an inverted T-shaped bar (5) and an auxiliary device, which is characterized in that the auxiliary device includes a fixed block (2) and a locking device, and the locking device is a pin hole (3) welded on the inverted T-shaped bar and connected with it The pin (4) used in conjunction is provided with a jack (6) on the fixed block, and the fixed block is located on the T-head (1) upper side of the inverted T-bar, and a rotary handle (7) is arranged above the inverted T-bar. The hoisting method includes steps such as land installation of the spreader, underwater installation of components, and underwater removal of the spreader. The utility model has the positive effects of simple and convenient operation, safety and reliability, and high work efficiency.
Description
technical field [0001] The invention relates to the technical field of hoisting of large prefabricated components, in particular to a device and method for hoisting large prefabricated components using an inverted T-shaped suspender. Background technique [0002] At present, with the development of water transportation engineering construction technology, the hoisting technology of concrete components is becoming more and more mature. However, in the construction of ports and wharfs, most of them use rings and "inverted T-shaped booms" as spreaders to hoist concrete components. When the "inverted T-shaped boom" is hoisted, because of the deep hoisting holes reserved, it is easy to cause the phenomenon of installation of the spreader on land, difficulty in removing the spreader underwater, and low work efficiency. Contents of the invention [0003] The object of the present invention is to provide a new type of large-scale prefabricated component hoisting device and method,...
