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.

Embodiment Construction
[0023] Such as figure 1 , figure 2 As shown, the large-scale prefabricated component hoisting device provided by the present invention has an inverted T-bar 5 and an auxiliary device. The auxiliary device includes a fixed block 2 and a locking device. The locking device is welded on the inverted T-bar The pin hole 3 and the pin 4 used in conjunction therewith are provided with an insertion hole 6 on the fixed block. The fixed block is located on the upper side of the T-shaped head 1 of the inverted T-bar, and a rotating handle 7 is arranged above the inverted T-bar.
[0024] The method for hoisting large-scale prefabricated components provided by the present invention firstly installs the spreader on land. The operator hoists the inverted T-shaped boom and the auxiliary device to the top of the component at the same time, and the constructor moves it synchronously to directly above the hoisting hole reserved for the component. ; Make the fixed block and the T head on the same hor...

The invention discloses a large-sized prefabricated part hoisting device and a hoisting method, relates to the technical field of the hoisting of a large-sized prefabricated part, and particularly belongs to a device and a method for hoisting the large-sized prefabricated part by utilizing an inverted T-shaped hoisting rod. The large-sized prefabricated part hoisting device is provided with an inverted T-shaped rod (5) and an auxiliary device, and is characterized in that the auxiliary device comprises a fixed block (2) and a locking device, the locking device consists of a pin hole (3) which is welded on the inverted T-shaped rod and a pin (4) which is matched with the pin hole to use, an insertion hole (6) is formed in the fixed block, the fixed block is arranged on the upper side of a T-shaped head (1) of the inverted T-shaped rod, and a rotating handle (7) is arranged above the inverted T-shaped rod. The hoisting method comprises the steps of installing a lifting appliance on the ground and installing parts under the water, and removing the lifting appliances under the water. The large-sized prefabricated part hoisting device has the beneficial effects of simplicity in operation, safety, reliability and high working efficiency.
Description
Technical field [0001] The invention relates to the technical field of hoisting large-scale prefabricated components, and particularly belongs to a device and method for hoisting large-scale prefabricated components by using an inverted T-shaped boom. Background technique [0002] At present, with the development of water transportation engineering construction technology, the concrete component hoisting technology is becoming more and more mature. However, in the construction of ports and wharfs, most of them use hoisting rings and "inverted T-shaped booms" as spreaders for hoisting concrete components. When the "inverted T-shaped boom" is hoisted, because the hoisting holes are reserved deeper, it is easy to cause problems such as difficulty in installing the sling on land, removing the sling underwater, and low work efficiency. Summary of the invention [0003] The purpose of the present invention is to provide a new type of large-scale prefabricated component hoisting device a...
