Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of inverted arch block hoisting device, especially a kind of inverted arch block hoisting mechanism. BACKGROUND

[0002] In recent years, TBM technology is more and more mature and widely used in domestic tunnel construction. Inverted arch block is the main component in the process of TBM excavation. After the inverted arch block is transported to the hoisting position of the supporting trolley of TBM, the hoisting device of the inverted arch block hoists and transports the inverted arch block to the installation position. Due to the limited space of the hoisting position of the inverted arch block on the TBM, and the heavy weight of the inverted arch block itself, the traditional inverted arch block hoisting device reserves the inverted arch block hoisting hole, which not only makes the inverted arch block prefabrication process more complex, but also increases the construction time.
